Mass Media and Younger Generation Essay

The media can definitely change your perception of intimacy, as well as alter your ability to be intimate. As the media displays false images of the human body and makes false descriptions of what humans desire sexually. There are too many subjects and issues to go on about here, but a small example of the two issues i mentioned before are in magazines the pictures of the models are airbrushed to display, what most call a â€Å"flawless† body and in movies and sitcoms the most desired people are medium height, and very slender and so on. Giving the receivers of this idea the false realization that’s what you have to have to be sexually attractive. which would cause embarrassment of their own bodies or thinking some thing is wrong if they are attracted to some one that’s 4 foot and heavy.Possibly leading them to involvement with someone they are not sexually attracted to and embarrassed to take their clothes off in front of. This is definitely, in my opinion, going to cause intimacy issues and is an excellent description of proof how mass media plays a role in shaping your meaning of intimacy. the mass media, including TV, radio, newspapers have a great influence on people and especially on the younger generation. It plays an important role in shaping the opinions and position of the younger generation. Argue for or against this statement. The peril from Mass media In the present, the younger generations are influenced by the mass media, including TV, radio, and newspapers. They think this is the model for them because in daily life is necessary for everyone therefore it is not unusual that it have a great influence on the people and especially on the younger generation. .It plays an important role in shaping the opinions and position of the younger generation. The younger imitate by the mass media and it has impact for younger that is impact for dressed, language, and behavior. Nowadays the younger or teen have been sensitive because the younger is the people who has been 13-18 years old and they want to find something for them that is their dream, acceptance from other people so they want to find inspiration and don’t have limited. So the mass media are important for the younger that they want to be the same the star or some thing when they think is good for them. If they were persuaded by vice maybe they will be scoundrel. Some of people are think it is unsuitable dressed. Although the younger want to be one that who are the modern of them. Some of people think it is suitable but the younger can not consider. The stars are good dress but adult think it is unsuitable. The mass media have good or bad but we do not know so we must warn you child before late time. However it has impact for family because when the younger use the mass media be the model neither it bad nor it not bad I think it is directly for the younger especially language. It was influenced by younger because when the stars are speaking, the younger are listen it I think they copy the speech from the stars if it is bad I think it is not good.

My Dream Job Essay

What is a bad boss or manager? We all have had some good managers and some bad managers. In most cases people don’t care too much for their boss. One of the biggest characteristics flaws in a poor manager is poor communications skills. They possess little to no listening skills and don’t seek out advice or suggestions from their employees. When a big decision needs to be made they normally make the decision on their own with little input from their subordinates. Another characteristic of a poor boss is a one who is afraid of confrontation. In management, I believe that any time there is an issue, the boss should not be afraid to address it. Some employees will take advantage and lose respect for their boss if that happens. I call those types of managers â€Å"buddy bosses,† which is not a good thing their needs to be a healthy balance. Bosses should be nice most of the time yet they also needs to be firm when the time calls for it. Good management skills don’t always come naturally. Managers have to continue to have ongoing training on leadership skills just like the workers need to have ongoing training on the jobs. In management; it is hard to please everyone in fact, if everyone is happy with you all the time you are probably a â€Å"buddy boss. † There will always come a time when you are going to have to say no to someone’s request. I believe that sometimes bad employees force a boss to become more firm most of with the employees. There are several types of bosses that I would consider bad. The first one is called an incompetent boss. They really don’t know the job and rely on the employee’s knowledge to get them through. When an issue occurs, they are no help at all. When an incompetent boss tries to help, they often make the situation worse. The second type of poor boss is a unchangeable leader. This is someone who does not like change and is unwilling to do what it takes to make the team more effective. This person doesn’t listen to the advice of the team, eve when they might tell them something that might help a process run smoother. The next type of poor leader I would call the abuser of power. They are people that get into leadership and use their power for personal gain. An example of this would be a boss that leaves early for the day all the time to take care of their personal business. The next type of poor leader is a leader that can’t be trusted. This is someone who employees don’t trust with information that can be used against them. When they have a problem the don’t feel comfortable talking to their leader in fear that they will tell someone else or use it against them in the future. They can’t tell them how they really feel. There is always going to be corrupt people in the world but when a leader is corrupt in any organization it breeds more corruption. There are some leaders that are down rite evil. They may have had a hard life and just don’t like to see others happy so they always find a reason to be upset and not satisfied with anything that is done within their department. Manager that operate in this manor normally don’t last long in leadership because there would make their employees unhappy and we all know that an unhappy employee won’t be a good producer. There ways to improve a bad boss if they want to improve. One way to do that is to make sure that middle level supervisors and managers have the support they need from upper management. I believe that leadership training should be an ongoing thing. I feel that in every organization there should be a hotline that employees can call to give feedback on how they feel their leadership is going. Once that feedback is collected it should be used as a training tool. Listening to the employees and responding to their needs and wants is in my opinion, the most effective way to go. During the hiring process employers should make sure that the leader they has the characteristic of a good leader. No one wants a bossy dictator as a boss. I have been in the workforce for over ten years and in that time I have had more good managers than bad. I think that is because it all comes down to respecting a person and there position. There have been times when my coworker s has come to me complaining about our boss. What I have found is that most of the time it not the boss at all it’s the employee view of their boss. Most people who don’t like their boss don’t like their job. I believe that if a person doesn’t like their job there is a likely chance they don’t like their boss because that the boss is only there to enforce the rules and doesn’t care employee’s personal feeling. In some cases they are right. The next time you are trying to determine if you have a good leader look for key traits. One key trait of a good boss is vision. Do they have a vision for the department that they will be managing? What is that vision? Does the vision line up with the companies mission statement? Ask yourself these questions. The next trait you should look for is wisdom. What useful knowledge can this person bring to the organization? Good leaders are strategic, wise and perceptive. The next question you should ask yourself about your boss is if he people are they passionate about what he or she does? Good bosses are very passionate people. They operate with such a high level of passion that they get consumed in it. They take action! Good leaders are determined to attain their goals. They know that the journey reaching their destination can be filled with problems. However, they are persistent people and are willing to put in the long hour and hard work to ensure that th eir goal is meet. Good leaders mean what they say. They have integrity. They’re individuals who keep their guarantees and they do not play the old political games that plenty of others do. People find them reliable and as such are dedicated to them. Not all good bosses carry every single trait. They might be strong in some areas and lacking in others. But just remember, it isn’t about being perfect, but understanding that bosses are human too; no one is perfect. Make an effort to try and get to know your boss and be a little more understanding about what they might be challenged with in their day to day duties.

Satellite Offices Help Improve Work-Life Balance

Satellite offices to help improve work-life balance TAN WEIZHEN – 09 MARCH SINGAPORE — To support the quest for better work-life balance, the Government will be carrying out various initiatives to support working from home, such as the introduction of satellite offices located nearer to homes. These Smart Work Centres will come with facilities and will be shared by employees of different companies, said Minister for Communications and Information Dr Yaacob Ibrahim, who also announced improvements to infrastructure for services like  [email  protected], during his ministry’s Committee of Supply debate yesterday.Noting that several Members of Parliament (MPs) had called for greater use of technology to boost productivity, Dr Yaacob said home-based work â€Å"can help Singaporeans better balance their work-life commitments and minimise travel during peak hours†. Singapore’s economy would also benefit from the increased labour force participation, w hile businesses could derive long-term cost savings in office space rental. The Infocomm Development Agency (IDA) is working with the National Library Board to pilot such centres at selected libraries.The Public Service will also be piloting this concept at several ministry buildings, including the Treasury, for use by public officers from participating agencies. The agency has also embarked on pilots for home-based work with six companies from the healthcare, education and telecommunications industries. Among them is home-nursing care provider Rasa Sayang, which allows nursing staff to access assignments and information on patients remotely.Meanwhile, the capacity and speed [email  protected]  will be ramped up and its login process simplified. Instead of having to repeatedly enter one’s login information, the improved network will be able to recognise registered users through the SIM cards in their phones. The IDA will also be revising the Code of Practice for Infocommu nication Facilities in Buildings to ensure buildings set aside adequate space to support quicker deployment of mobile services.Telcos have long had issues with building owners who either delayed the process or rejected such requests, leading to a slowdown in works to improve the mobile networks. Five MPs yesterday called for the greater use of ICT to help businesses, especially small and medium enterprises, to boost their productivity, as they undergo restructuring over the next few years.Mr Sitoh Yih Pin (Potong Pasir) said: â€Å"This can include a one-stop training centre to equip SME staff with the skills to use ICT, as well as getting SME owners to adopt ICT in their business in a holistic way, so as to overcome the current and near future manpower crunch. † Mr Low Thia Khiang (Aljunied GRC) added that internet speed is critical to home-based work initiatives, and questioned why speed is not part of the IDA’s quality standards. Responding, Dr Yaacob said the minis try does its own studies for broadband speeds. Tan Weizhen

Philosophy - Essay Example ble in the sense that it does not label any theories wrong, but treats all assumptions and viewpoints, even the most controversial ones, as possible and justified. The notion of philosophy and the search for wisdom are closely associated with ethical behaviors and metaphysics. That the value of ethics is metaphysical cannot be denied: ethical statements and prescriptions are equally absolute, constraining, and metaphorical, i.e., they are difficult to explain by factual language. In my opinion, the metaphysics of ethics assigns individuals with the responsibility to follow the principal ethical commands without trying to understand the philosophic utility of these ethical standards. Simply stated, the philosophy of life is in complying with the society’s ethical demands, without looking too far into their distant meanings and effects. Here, I cannot but agree to Wittgenstein in that ethics is a road which everyone must go or be ashamed for not going, but the meaning of such a road can hardly be explained, as long as it lies beyond the realm of explicable things (7). Whether we have more knowledge than the ancients is a complex issue. We live at the time of the rapid technological and knowledge advancement and sometimes come to view ourselves as the people, who know (or can know) everything about anything. However, there are still things which we cannot explain. More importantly, most of our knowledge is rooted in the facts, theories, and opinions produced by our predecessors. Objectively, there are things which were available to the ancients but are unavailable to us, and there are things of which previous generations were unaware. The point is in being able to value, preserve, enrich, and use the knowledge of the ancients to build a more systematic vision of the world – the goal any philosopher seeks to pursue. In this context of ethics, metaphysics, and philosophy, the question is in what place God occupies and whether God must be moral and happy. Some

Unit Journal - Essay Example Indeed, the economic integration through liberalization of trade and de-regulation by the states has redefined global economy in terms of inter-dependency of resources. Most importantly, it is designed towards more equitable distribution of resources vis-Ã  -vis goods and human capital across the geographical boundaries. Role of non state actors is emphasized in conflict resolution, negotiation process and raising issues that influence common interests like international peace, environment and sustainable development, human rights, financial aid etc. The barriers in cooperation develop due to exigencies and political dichotomy within the states and nexus between goals of non state actors and international trade (Gourevitch, 2002). The external factors like socio-economic, political and environment have huge impact on trade. They create a nexus between the non state actors and issues that considerably impact civil society. Stiglitz (2007) says that interests of nations are compromised by the American hegemony in the international financial institutes like World Bank and IMF. NGOs mostly use social concerns to influence international trade policies and methods of operations. As such, major barrier to cooperation occurs when the wider interests of the society are threatened by the vested interests of the few like TNCs and international agencies and financial institutions which are influenced by powerful nations like America. (words: 302) Within the broader precinct of security, the national and international policies that address the factors which are threat to people and climate, have emerged as vital issues in international relations. Climate security is intrinsically linked to human security (ipcc, 2008). The limited natural resources like water, land and fresh air are being taken for granted with scarce regard for

As a group, we performed relatively well. Several issues came up in the course of the meeting and it affected the way in which we completed the task. The lecturer required that we form our own groups that we would all be comfortable working with. This we did, and it was convenient to us because we had similar background in terms of the course we studied at the university and this made us to cope well. In addition, we had worked previously together in group work for other subjects that we studied together. In the course of the group work, several issues manifested themselves as we worked together. Time management was not accomplished well because some group members lived far away from the university and therefore, the time that we had agreed on was at no particular adhered to and we obviously had to accommodate all group members in order to work as a team. Conflict in the process of group work was a big issue that arose. At times, the participants in the group openly attacked each other and this at one point brought the discussion to a halt for some time. The way the group members stated some major points during the discussion brought out both the negative and positive criticism. Despite all these challenges, we were finally able to complete the assignment on time. What I would change to the process. For the group members who were not living within the university, I would ensure that we set the time that is convenient to them and comfortable to us as a team. I would convince other group members to agree on a time limit in which the discussion would take. For instance, one hour for each meeting scheduled to take place so as to allow the affected persons to attend and leave the meeting at their own pleasure. In the issue of conflict, I as the group leader would ensure that if there were any disagreements, they would be constructive and not directed to any particular person. I would also ensure that there was room for free expression of thoughts while coordinating the group and encourage criticism (Hansen, et al 2002). How to improve performance as a group. I as the group leader would manage the group well for it to work effectively. I would ensure that the set aims and objectives of the group work are incorporated from each and every member. For example, all participants in the group would make contributions in the setting of aims and objectives. This would help each individual develop personally .The group would also benefit as a whole. Other benefits would be to that the participants would learn academically. We would also ensure that the responsibilities that we adapt help us to achieve the desired success together. My individual role and contribution. My group members

Fashion industry management Essay Example | Topics and Well Written Essays - 2500 words

Fashion industry management - Essay Example According to the research findings it can therefore be comprehended that the fashion industry is fast moving and extremely trendy. Working in a fashion company requires one to keep up with fashion trends and to be open about adapting with fashion services and products. An advantage in working with a fashion company is that there is no need to get tied up with a single product for a long time because it is possible to change offerings on a frequent basis. Such circumstances create the necessity to remain open about new fashions and trends. It is beneficial to establish link with fashion professionals such as models, socialites, trend setters, stylists and designers. This helps a great deal in establishing good relations with manufacturers and distributors of fashion products, but the specific relationship depends upon the kind of business that is being considered. It is important for fashion companies to organize fashion shows to attract attention to the business, in addition to hirin g publicists and event planners to make the events successful. In view of the extensive competition in the fashion industry it is better to keep finding new ways to reduce costs. Pricing policy should be adopted whereby the consumer gets value for his money. In addition to complying with these processes, one must keep a close tab on the budget as provided for in the business plans. Fashion is a wide term that includes products or markets characteristically encompassing elements of style that tend to be short lived. Fashion markets mostly exhibit certain characteristics such as short life cycles, high volatility, low predictability and high impulsive purchases. Fashion products are typically transient because they are designed for capturing the mood of people during any given period. Therefore, the period in which a fashion product is sold will mostly be ephemeral; a few months or weeks. The demand for fashion products are seldom stable and are prone to be impacted by the vagaries of weather or the actions of sports personalities or pop stars. It is extremely difficult to forecast the demand of fashion products because of the given unpredictability. Most purchase decisions for fashion products are made on impulse at the points of sale because consumers are motivated to buy the product only after seeing what varieties and items are available. The fashion industry is also known as the Rag Trade because the involvement of designer clothes and high fashion creates difficult and competitive market conditions. The business environment is characterized with constant change as fashions and trends keep coming and going. The working of a fashion company can be bifurcated into four distinct sections; retailing, wholesaling, manufacturing and designing. But all these functions complement each other, which clearly reveal that the industry is more about information than just clothing and design. In this industry, people are required to make a place for themselves in a social environment and to associate with specific social groups. It is recognized that fashion products are a means of communication and make statements about the individual wearing them, in identifying him or her with a specific group. Changing fashions demonstrate the working of a dynamic system and such changes are irregular and vary with circumstances. There are times when people in the industry experience a literal chaos in terms of the mixture of fashions that may exist at one time and then suddenly a new emergent style replaces them, thus making it imperative for the fashion company to change its strategies and goals. Under these circumstances, I realized that it is better to ignore

Pharmacy Essay Example | Topics and Well Written Essays - 1500 words

Pharmacy - Essay Example Of course, there are many other formulations that I could become as a drug: powder, gel capsules, even nasal spray. But the most common types are the tablet and suspension forms. All of the equipment I come into contact with between now and when I am ingested by a patient must be clean and sterile. I must be sealed away from outside contact, so that I do not become contaminated with debris, bacteria, or other microscopic particles. Every canister, tank, mixer, pipe, hose, and bottle has to be sterilized completely. Many of the items I will come in contact with have been steam-sterilized, because using clean steam prevents me from being contaminated by the cleaning products themselves. I am pumped from a delivery vehicle into a tank to be stored at the manufacturing site. The tank I am in is only one of many in the tank farm at this pharmaceutical plant. In order to assure safety, the tanks are sterilized before I am pumped into them through an airtight transfer pump. After a period o f storage, I am then pumped from the storage tanks into a make-up and boot tank, and then from there into a reactor tank to start the manufacturing process. The plant keeps very careful track of the arrival times of all the ingredients for their products, including me, in order to ensure that nothing is stored too long. They also have to keep track of the temperature and humidity of the storage areas, because some ingredients cannot be exposed to temperatures that are too high or too low, and some cannot be exposed to humid air in case they react with the oxygen. Some chemicals must even be kept away from contact with the oxygen in the air, because they will oxidize and change form. At the start of the manufacturing process, I am weighed with great precision, as are the excipients that will make up the tablets or suspension with me. The weights of the various ingredients will depend on batch size and dosage amount, and all of the weights are recorded for quality assurance. Each of t he ingredients are all weighed individually in separate sterile canisters because having the right amounts of each ingredient is vital to the properties of the final product. The reactor mixes us together in the right proportions, according to the size of the batch and the dosage amount of the final product. Depending on my properties and the properties of the other ingredients in my mixture, the next steps will vary. If I and the other active and inactive ingredients are dry powder that can be mixed together smoothly, we can be sent on to the next step of tablet pressing without further processing. If the right mixtures cannot be obtained through simple stirring in the reactor, there are two other possibilities to create the necessary homogeneity of the mixture for the creation of tablets. These possibilities are wet granulation or dry granulation. If I can be mixed with water, the manufacturer will use an aqueous solution, as that will be safer; if, like many pharmacological chemi cals, I cannot come in contact with water without reacting to it and degrading, I will be mixed with a solvent solution. If I go through wet granulation, a liquid binder-adhesive will be added to me in the reactor, where we will be thoroughly mixed together. Using the correct amounts of the liquid binder-adhesive is vital, because if too much of the liquid is added to me, my granules will come out to be too

Should drivers pay fine for talking on cell phones or texting while Essay

Should drivers pay fine for talking on cell phones or texting while they drive - Essay Example e increasingly focusing on building mobile phones into car systems, the debate surrounds around not the device being hand-held or hands-free; rather the debate is on the act of phone communication. Although some people may argue about safety regarding hands-free devices, it is the topic of conversation that can distract the attention level of drivers. However, due to the extreme importance of cell phones in modern life drivers do not heed the dangers associated with using the device while driving. Therefore, it is necessary that laws need to be applied to discourage drivers from using cell phones. Despite the conveniences of using cell phones in modern days of communication, drivers should be fined for talking and texting while driving because doing so texting and talking increases the probability of accidents, they put lives at danger, and they are a driving distraction. Texting and talking while driving increase the probability of accidents. Let me begin by giving some statistical figures to prove my point of argument. According to an estimation given by CDC report, every day in the United States 9 people meet with fatal accidents and 1,153 people get injured as a result of mishaps caused by a distracted driver. A driver becomes distracted when he remains busy doing activities other than driving that include talking on the cell phone or texting. A study was conducted by CDC in 2011 to analyze the reasons of distraction. It was revealed that 69 percent of U.S. drivers between the age of 18 to 64 have talked on their cell phone while driving in the 30 days prior to the study. In Europe, it was 21 percent in UK and 59 percent in Portugal (â€Å"Distracted Driving†). According to another 2011 report by National Highway Traffic Safety Administration (NHTSA), distracted drives attribute towards 22 percent of injuries and 16 percent of deaths by ro ad accidents (Trempel et al., 6). In another report published by the U.S. government, in the year 2008, 6,000 people have

Ethics in Health Care Services Essay Example | Topics and Well Written Essays - 1750 words

Ethics in Health Care Services - Essay Example There are exceptions in Ethics Code in extraordinary circumstances where health providers with closely related expertise can offer services if no one else can (Beauchamp & Childress, 2001). It is, however, to a condition that they take a reasonable approach to acquiring competence required.Respect of people’s autonomy forms another crucial tool in minimizing cases of unethicality in the health sector (Duncan, 2010). Health care providers need to offer clients with the information they require to give their informed accord at the start. Failure to give details may cause sticky situations. For example, when a health practitioner fails to explain own duty to report abuse to an adolescent client before treatment commences, an unsure scene may occur if abuse is later revealed the client did not want to report. Important discussion should be the estimated length of therapy, fees, and billing practices, whom to involve in case of emergency and any alternative treatment approaches.Whe n one of his twins died and one survived with brain injuries, Charles Munro argued that the results came about, because of year’s delay in handling the physiotherapy. He complained that, the delay was unacceptable as the disciplinary measures of those involved aimed at safeguarding everybody. He complained of the inaction of the ministry and Minister of Health.Munro viewed that the physiotherapy requires maximum care and dedication to ensuring the achievement of maximum results. If practitioners can take, maximum care to their parents.

Responsibilities of an Authorized Supervisor - Essay Example The Regulation necessitates facilities to install safety glass – if the Building Code of Australia necessitates the area to be furnished with safety glass, or put on glass treatments to glass installed on the buildings below 75 meters in areas reachable to children. As an all-purpose rule this would only be valid for glass – in doors, windows however, where there is other glass in these areas that is deliberated to pose a threat to children, the facility should safeguard the glass from breakage, put a an obstruction in front of it, or take it away from the area (Services, 2004).1.3 Maintaining the Group sizesThe largest group size for children from three to five years of age is condensed from 25 to 20.

Design Of Wastewater Treatment Plant Environmental Sciences Essay

Design Of Wastewater Treatment Plant Environmental Sciences Essay Industrial wastewater treatment covers the mechanisms and processes used to treat waters that have been contaminated in some way by industrial or commercial activities prior to its release into the environment or its re-use. It involves mainly three stages, called primary, secondary and tertiary treatment. Activated sludge process can be used to treat the wastewater produces from Oushadi Ayurvedic Pharmaceuticals. Contaminants include oils, particulate solids, materials having high concentrations of biochemical oxygen demand (BOD) and suspended solids (SS). Primary treatment consists of temporarily holding the sewage ,where heavy solids can settle to the bottom while oil, grease and lighter solids float to the surface. The settled and floating materials are removed and the remaining liquid may be discharged or subjected to secondary treatment. One major problem faced by Oushadi was the complete removal of oil from wastewater and this posed a threat to the use of treated water for the ir boilers. Secondary treatment removes dissolved and suspended biological matter. Secondary treatment is typically performed by natural, water-borne micro-organisms in a managed habitat. Secondary treatment may require a separation process to remove the micro-organisms from the treated water prior to discharge or tertiary treatment. Tertiary treatment is sometimes defined as anything more than primary and secondary treatment. Comprising over 70% of the earths surface, water is undoubtedly the most precious natural resource that exists on our planet. Recycling of wastewater in industries is therefore a process, which is a necessity rather than a luxury. Wastewater treatment is the process of removing contaminants from wastewater. It includes physical, chemical, and biological processes to remove physical, chemical and biological contaminants. Its objective is to produce a waste stream (or treated effluent) and a solid waste or sludge suitable for discharge or reuse back into the environment. This material is often inadvertently contaminated with many toxic organic and inorganic compounds. Wastewater can cause contamination of ground water, lakes, streams and rivers. It wastes and decreases the amount of potable water available on earth, causes an imbalance in aquatic ecosystems and wastes the nutrients contained in wastewater by not recycling them. Many industries use large volumes of water in their manufa cturing operations. Because some of this water becomes contaminated, it requires treatment before discharge. Improvements in determining the effects of industrial waste discharges have led to the adoption of stringent environmental laws, which define the degree of treatment necessary to protect water quality. Discharge permits, issued under the National Pollutant Discharge Elimination System (NPDES), regulate the amount of pollutants that an industry can return to the water source. The permitted quantities are designed to ensure that other users of the water will have a source that meets their needs, whether these needs are for municipal water supply, industrial or agricultural uses, or fishing and recreation. Consideration is given to the feasibility of removing a pollutant, as well as the natural assimilative capacity of the receiving stream. This assimilative capacity varies with the type and amount of pollutant. Wastewater treatment plants are designed to convert liquid wastes into an acceptable final effluent and to dispose of solids removed or generated during the process. In most cases, treatment is required for both suspended and dissolved contaminants. Special processes are required for the removal of certain pollutants, such as phosphorus or heavy metals. Wastewater can be recycled for reuse in plant processes to reduce disposal requirements. This practice also reduces water consumption. Sahradaya College Of Engineering Technology, Kodakara 1 Design Of Wastewater Treatment Plant 1.1 POLLUTANTS IN WASTEWATER Organic Compounds The amount of organic material that can be discharged safely is defined by the effect of the material on the dissolved oxygen level in the water. Organisms in the water use the organic matter as a food source. In a biochemical reaction, dissolved oxygen is consumed as the end products of water and carbon dioxide are formed. Atmospheric oxygen can replenish the dissolved oxygen supply, but only at a slow rate. When the organic load causes oxygen consumption to exceed this resupply, thus dissolved oxygen level drops, leading to the death of fish and other aquatic life. Under extreme conditions, when the dissolved oxygen concentration reaches zero, the water may turn black and produce foul odours, such as the rotten egg smell of hydrogen sulphide. Organic compounds are normally measured as chemical oxygen demand (COD) or biochemical oxygen demand (BOD). Nutrients Nitrogen and phosphorus are essential to the growth of plants and other organisms. However, nitrogen compounds can have the same effect on a water source as carbon- containing organic compounds. Certain organisms use nitrogen as a food source and consume oxygen. Phosphorus is a concern because of algae blooms that occur in surface waters due to its presence. During the day, algae produce oxygen through photosynthesis, but at night they consume oxygen. Solids Solids discharged with a waste stream may settle immediately at the discharge point or may remain suspended in the water. Settled solids cover the bottom-dwelling organisms, causing disruptions in population and building a reservoir of oxygen-consuming materials. Suspended solids increase the turbidity of the water, thereby inhibiting light transmittance. Deprived of a light source, photosynthetic organisms die. Some solids can coat fish gills and cause suffocation. Sahradaya College Of Engineering Technology, Kodakara 2 Design Of Wastewater Treatment Plant Acids and Alkalies The natural buffering system of a water source is exhausted by the discharge of acids and alkalies. Aquatic life is affected by the wide swings in pH as well as the destruction of bicarbonate alkalinity levels. Metals Certain metals are toxic and affect industrial, agricultural, and municipal users of the water source. Metals can cause product quality problems for industrial users. Large quantities of discharged salts necessitate expensive removal by downstream industries using the receiving stream for boiler makeup water. The contaminants in wastewater are removed by physical, chemical and biological methods. The specific method are classified as physical unit operations, chemical unit processes and biological unit processes. 1.2 Unit Operations and Process in Wastewater Treatment TABLE 1.1 Operations and Process in Wastewater Treatment Contaminant Unit Operations/ Processes Classifications Suspended solids Screening Sedimentation Floatation Filtration Physical Biodegradable Organics Activated Sludge Trickling Filters Rotating Biological Contactors Biological Phosphorus Lime Coagulation Chemical Heavy Metal Chemical Precipitation Chemical Sahradaya College Of Engineering Technology, Kodakara 3 Design Of Wastewater Treatment Plant CHAPTER 2 WASTEWATER CHARACTERISTICS 2.1 WASTEWATER CHARACTERISTICS To design a treatment process properly, characterization of wastewater is perhaps the most critical step. Wastewater characteristics of importance in the design of a treatment process can be grouped into the following categories:  · Temperature  · pH  · Colour and Odour  · Carbonaceous substrates  · Nitrogen  · Phosphorous  · Chlorides  · Total and volatile suspended solids (TSS and VSS)  · Toxic metals and compounds  · Density  · Oil grease  · Alkalinity 2.1.1 Temperature: The temperature of wastewater is commonly higher than that of the local water supply, because of the addition of warm water from household activities. As the specific heat of water is much greater than that of air, the observed wastewater temperatures are higher than the local air temperatures during most of the year and are hotter only during the hottest summer months. Depending on the location and time of the year the effluent temperatures can either higher or lower than the corresponding influent values. 2.1.1.1 Effect of temperature The temperature of water is a very important parameter because of its effect on chemical reactions and reaction rates, aquatic life, and the suitability of the water for beneficial purposes. In addition, oxygen is less soluble in warm water than in cold water. The increases in rate of biochemical reactions that accompanies an increase in temperature, combined with the decrease in the quantity of oxygen present in surface waters, can often cause serious depletions in dissolved oxygen concentrations in summer months. Optimum temperatures for bacterial activity are in range from 25 to 35oC.Aerobic digestion and nitrification stops when the temperature rises to 50oC. When the temperature drops to about 15oC, methane producing bacteria become quite inactive and at about 5oC, the autotrophic nitrifying bacteria practically Sahradaya College Of Engineering Technology, Kodakara 4 Design Of Wastewater Treatment Plant cease functioning. At 2oC, even the chemo heterotrophic bacteria acting on carbonaceous material become essentially dormant. 2.1.2 pH: The hydrogen ion concentration is an important quantity parameter of both natural waters and wastewaters. The usual means of expressing the hydrogen ion concentration is as pH, which is defined as the negative logarithm of hydrogen ion concentration. The concentration range for the existence of most biological life is quite narrow and critical typically 6 to 9. Wastewater with a extreme concentration of hydrogen ion is difficult to treat by biological means, an if concentration is not altered before discharge, the wastewater effluent may alter the concentration in the natural waters. For treated effluents, discharged to the environment the allowed pH range usually varies from 6.5 to 8.5. The pH of fresh domestic waste water is slightly more than that of the water supply to the community. However, the onset of septic conditions may lower the pH while the presence of industrial wastes may produce extreme fluctuations. 2.1.3 ODOUR AND COLOUR: Fresh domestic waste water has slightly soapy and earthy odour and cloudy appearance depending upon its concentration, With the passage of time, the waste water becomes stale, darkening in colour with a pronounced colour due to microbial activity. 2.1.3.1 Odour: Odours are usually caused by gases produced by the decompositions of organic matter or by substances added to the waste water. Fresh wastewater has a distinctive, somewhat disagreeable odour which is less objectionable than the odour of wastewater which has undergone anaerobic decomposition. The most characteristic odour of stale or septic wastewater is hydrogen sulfide. Odours have been rated as the foremost concern of public relative to wastewater treatment facilities. Within the past few years, the control of odour has become major consideration in the design and operation of wastewater collection, treatment and disposal facilities, especially with respect to public acceptance of these facilities. Effect of Odours: The importance of odours at low concentrations in human terms is related primarily to psychological stress they produce rather than to the harm they do to the body. Offensive odours can cause poor appetite, lower water consumption, impair respiration, nausea and vomiting and mental perturbation. Some odorous compounds are toxic at elevated concentrations. Sahradaya College Of Engineering Technology, Kodakara 5 Design Of Wastewater Treatment Plant 2.1.3.2 Colour: Historically, the term condition was used along with composition and concentration was used to describe waste water. Conditions refer to the age of wastewater, which is determined qualitatively by its colour and odour. Fresh wastewater is usually a light brownish grey colour. However as the travel time in collection system increases, and more anaerobic conditions develop, the color of waste water changes sequentially from grey to dark grey and ultimately black . When the color of wastewater is black, the wastewater is described as septic . In most cases the grey , dark grey and black color of wastewater is due to formation of metallic sulphites which form as the sulphide produced under anaerobic conditions react with metals in the wastewater. 2.1.4 CARBONACEOUS CONSTITUENTS: Carbonaceous constituents are measured by BOD, COD or TOC analyses. While the BOD has been the common parameter to characterize carbonaceous material in wastewater, COD is becoming more common in most current comprehensive computer simulation design models. 2.1.4.1 Biochemical Oxygen demand: The BOD test gives a measure of the oxygen utilized by bacteria during the oxidation of organic material contained in a waste water sample. The test is based on the premise that all the biodegradable organic material contained in the wastewater sample will be oxidized to CO2 and H2O, using molecular of oxygen as the electron acceptor. Hence, it is a direct measurement of oxygen requirements and an indirect measure of biodegradable organic matter. 2.1.4.2 Chemical oxygen demand: The COD test is based on the principal that most organic compounds are oxidized to CO2 and H2O by strong oxidizing agents under acid conditions. The measurement represents the oxygen that would be needed for aerobic microbial oxidation, assuming that all organics are biodegradable. 2.1.4.3 Total Organic Carbon: The total carbon analyzer allows a total soluble carbon analysis to be made directly on an aqueous sample. In many cases TOC can be correlated with COD and occasionally with BOD values. Sahradaya College Of Engineering Technology, Kodakara 6 Design Of Wastewater Treatment Plant Table 2.1: Definition of Solids Found in Wastewater Test Description The residue remaining after a wastewater Total Solids (TS) Total Volatile Solids(TVS) sample has been evaporated and dried at a specified temperature (103-105oC). Those solids that can be volatilized and burned off when the TS are ignited (500 ±50 oC). oTotal Fixed Solids (TFS) The residue that remains after TS are ignited (500 ±50 C). Portion of the TS retained on a filter with a specified pore size, measured after being dried at a specified temperature (105oC). The Total Suspended Solids (TSS) Volatile Suspended Solids (VSS) Settle able Solids filter used most commonly for the determination of TSS is Whatman glass fiber filter which has a nominal pore size of about 1.58 µm. Those solids that can be volatilized and burned off when the TSS are ignited (500 ±50 oC). Suspended solids, expressed as mL/L, that will settle out of suspension with in a specified period of time. Sahradaya College Of Engineering Technology, Kodakara 7 Design Of Wastewater Treatment Plant CHAPTER 3 STAGES OF WASTEWATER TREATMENT 3.1 STAGES OF WASTEWATER TREATMENT 1) Preliminary Treatment: Removal of wastewater constituents such as rags, sticks, floatable grit and grease that may cause maintenance or operational problems with treatment operations, process and ancillary systems. 2) Primary treatment: Removal of a portion of suspended solids and organic matter from the wastewater. 3) Advanced Primary: Enhanced removal of suspended solids and organic matter from the wastewater typically accomplished by chemical addition to wastewater. 4) Secondary treatment : Removal of biodegradable organic matter (in solution or suspension) 5) Secondary with nutrient removal: Removal of biodegradable organics, suspended solids and nutrients. (N2, P or both N2 and P). 6) Tertiary treatment: Removal of residual suspended solids (after secondary treatment) usually by granular medium filtration or micro screens. Disinfection is also typically a part of tertiary treatment. Nutrient removal is often included in this definition. 7) Advanced Tertiary: Removal of dissolved and suspended materials remaining after normal biological treatment when required for various water reuse applications. 3.2TREATMENT PROCESS FLOWSHEET: Depending on the contaminants to be removed, an almost limitless number of process combinations can develop using the unit operations and process. The term flow sheet is used to describe particular combinations of unit operations and process used to achieve a specific treatment objective. Apart from the analysis of the technical feasibility of the individual treatment methods, the exact flow-sheets configuration will depend on factors such as (1) the needs of the of the clients needs, (2) the designers past experience, (3) regulatory agency policies on the application of specific treatment methods, (4) the availability of equipment suppliers, (5) what use can be made of existing facilities, (6) the availability of qualified operating personnel, (7) initial construction costs and (8) future operation and maintenance costs.

Secondary Removal of biodegradable matters and suspended solids Secondary with Nutrient removal Removal of biodegradable organics and nutrients. Tertiary Removal of residual suspended solids usually by granular medium filtration or micro screen Sahradaya College Of Engineering Technology, Kodakara 9 Design Of Wastewater Treatment Plant CHAPTER 4 LITERATURE REVIEW 4.1 SCREENING The first unit operation generally encountered in wastewater is screening. A screen is a device with opening, generally of uniform size, that is used to retain solids found in the influent wastewater to the treatment plant. The principle role of screening is to remove coarse material from the flow stream that could damage subsequent process equipment, reduce overall treatment process reliability and effectiveness and contaminate waterways. Fine screens are sometimes used in place of or following coarse screens where greater removal of solids are required to protect process equipment and eliminate materials that may inhibit the beneficial reuse of bio-solids. All aspects of screening, removal, transport and disposal must be considered in the application of screening devices including 1. The degree of screening removal required, because of potential effects of downstream processes 2. Health and safety of operators as screenings contain pathogenic organism that attract insects 3. Odour potential 4. Requirements for handling transport and disposal 5. Disposal options Two general types of screens, coarse screens and fine screens are used in preliminary treatment of wastewater. Coarse screens have clear opening ranging from 6 -150mm, Fine screens have openings ranging less than 6mm. Micro screens will generally have screen opening less than 50 µ m, are used principally in removing fine solids from treated effluents. Bar rack for the removal of coarse solids. 4.2 GRIT REMOVAL Removal of grit from wastewater may be accomplished in grit chambers or by the centrifugal separation of solids. Grit chambers are designed to remove grit, consisting of sand, gravels, cinders or other heavy solid materials that have subsiding velocities of specific gravities substantially greater than those of the organic putrescible solids in wastewater. Grit chamber are most commonly located after the bar screen and before the primary sedimentation tanks. Sahradaya College Of Engineering Technology, Kodakara 10 Design Of Wastewater Treatment Plant Locating grit chamber ahead of wastewater pump when desirable, would involve placing them at considerable depth at added expense. It is therefore deem more economical to pump the wastewater, including the grit to grot chamber located at a convenient position ahead of the treatment plant units, recognising that pumps may require greater maintenance. 4.2.1 Why Grit is removed?  · Prevent wear on pumps  · Accumulation in clarifiers  · Accumulation in aeration tank  · Accumulation in digesters  · Clogging of sludge piping 4.2.2 TYPES OF GRIT CHAMBERS Grit chambers are provided to (1) Reduce formation of heavy deposits in pipelines, channels and conduits (2) reduce the frequency of digester cleaning caused by excessive accumulation of grit (3) Protect moving mechanical equipment from abrasion and accompanying abnormal wear. There are three general type of grit chamber: Horizontal flow either rectangular or square configuration; aerated or vortex type. The aeration type consists of a spiral flow aeration tank where the spiral velocity is induced and controlled by the tank dimension in and quantity if air supplied to the unit. The vortex type consists of cylindrical tank, in which the flow enter tangentially vortex flow pattern; centrifugal and gravitational forces causes the grit to separate. Design of grit chamber is commonly based on removal of grit particles having a specific gravity of 2.65 and wastewater temperature 15.5oC. However analysis of grit removal data indicates the specific gravity ranges from 1.3-2.7. Horizontal Flow Grit Chambers In the horizontal flow type the flow passes through the chamber in a horizontal direction and the straight line velocity of flow is controlled by the dimension of the unit, an effluent distribution gate and a weir at the effluent end. Rectangular and square Horizontal flow grit chambers have been used for many years. Sahradaya College Of Engineering Technology, Kodakara 11 Design Of Wastewater Treatment Plant Typical Design Information for Horizontal Flow Grit Chamber Table 4.1 Item Detention time Horizontal velocity Settling velocity for removal of .21mm material Settling velocity for removal of .15mm material SI Unit Range Typical s 45-90 60 m/s .25-.4 .3 m/min 1-1.3 1.15 m/min .6-.9 .75 % 30-40 36 % 25-50 30 Head loss in a control section as % depth in channel Added length allowance for inlet and outlet turbulence Horizontal- Velocity Grit Chambers: They are controlled by either a  · Parshall flume  · Proportional weir Parshall fume is used more widely due to less head loss than the weir. The flume and weir are also used to measure flow rates. In the chamber, a constant horizontal velocities is maintained by proper cross-sectional geometry of the chamber.  · Horizontal velocity must be adequate to keep the organic matter in suspension.  · Horizontal velocities should be sufficient so as to prevent scouring of settled grit along the bottom of the channel. Values of .23-.38m/s are common. 4.3 FLOW EQUALIZATION Process for water treatment works best with uniform conditions. Shock to the bioprocesses in the form of sudden change in the concentration of nutrients can upsets. If the concentrations or flow rates of the waste vary greatly, dosages for treatment must be constantly be readjusted. Flow equalization is a method used to overcome the operational problems caused by flow rate variation, to improve the performance of downstream process, and to reduce the size and cost of t downstream treatment facilities. Flow equalisation is damping of flow rate variations to achieve a constant or nearly constant flow rate and can be applied in a number of different situations depending on characteristics of collection system. There may be aeration both to keep the fluid from becoming anaerobic and smelly and to biodegrade some of the organic compound present. Sahradaya College Of Engineering Technology, Kodakara 12 Design Of Wastewater Treatment Plant The principle applications are for the equalisation of: 1. Dry weather flow to reduce the peak flow and loads. 2. Wet weather flow in sanitary collection systems experiencing inflow and infiltration. 3. Combined storm water and sanitary system flows. In the line arrangement all of flow passes through equalisation basin. This arrangement can be used to achieve considerable amount of concentration and limits its divert into equalisation basin. Although the pumping requirements are reduced in this arrangement, the amount of constituents concentration damping is considerably reduced. The principle benefits that are cited as derived from application of flow equalisation are: 1. Biological treatment is enhanced, because shock loadings are eliminated or minimised, inhibiting substances can be diluted and pH can be stabilised. 2. The effluent quality and thickening performance of secondary sediment tank following biological treatment is improved consistency in solid loading. 3. Effluent filtration surface area requirements are reduced, filtered performance is improved and more uniform filter back wash cycles are possible by lower hydraulic loading. 4. In chemical treatment, damping of mass loading improves chemical feed control and process reliability. 5. Often the rest of the plant designed with a smaller equipment( less capital investment) because of this improvement in performance. Disadvantage of flow equalisation include  · Relatively large land areas are required.  · Equalisation facilities may have to be covered for odour control near residential area.  · Additional operation and maintenance required  · Capital cost is increased. 4.4 PRIMARY SEDIMENTATION The objective of treatment by sedimentation is to remove readily settle able solids and floating materials and thus reduce the suspended solids content. Primary sedimentation is used as a preliminary step in the further processing of the waste water. Efficiently designed and operated primary sedimentation tanks should remove from 50-70% of the suspended solids and from 25-40% of the BOD. Sedimentation tanks have also been used as storm water retention tanks which are designed to provide a moderate detention period (10-30mins) for overflows from either combined sewers and storms sewers. The purpose of sedimentation is to remove a substantial portion of organic solids that otherwise would be discharged directly to the receiving waters. Sedimentation tanks have also been used to provide detention periods sufficient for effective disinfection of such overflows. Sahradaya College Of Engineering Technology, Kodakara 13 Design Of Wastewater Treatment Plant 4.4.1DESCRIPTION Almost all treatment plants are mechanically cleaned sedimentation tanks of standardized circular or rectangular design. The selection of the type of sedimentation unit for a given application is governed by the size of the installation, by rules and regulations of local control authorities, by local site conditions and by the experience and judgment of the engineer. Two or more tanks have to be provided so that the process may remain in operation when one tank is out of service for maintenance and repair work. RECTANGULAR TANKS Rectangular sedimentation tanks may use either chain and flight solids collectors or travelling bridge type collectors. The solids settling in the tank are scraped solids hoppers in small tanks and transfers troughs in large tanks. In every long unit two collection mechanisms can be used to scrape solids to collection points near the middle of the tank length. Where possible, it is desirable to locate solids pumping facilities close to the collection hoppers. 4.4.2 SEDIMENTATION TANK PERFORMANCE The efficiency of sedimentation basins with respect to removal of BOD and TSS is reduced by 1. Eddy currents formed by inertia of incoming fluid 2. Wind induced circulation cells formed in uncovered tanks 3. Thermal convection currents BOD AND TSS REMOVAL R= Where R expected removal efficiency t- detention time a, b empirical constants 4.4.3 DETENTION TIME The bulk of finely divided solids reaching primary sedimentation tanks is incompletely flocculated but is susceptible to flocculation. Flocculation is aided by eddying motion of the fluid within tanks and proceeds through the coalescence of fine particles at a rate that is a function of their concentration and of the natural ability of the particles to coalesce upon collision. Coalescence of a suspension of solids becomes more complete as time elapses, thus detention time is a consideration in the design of sedimentation tank. Normally primary sedimentation tanks are designed, to provide 1.5-2.5hrs of detention based on the average rate of waste water.

temperature on the activity of liver

temperature on the activity of liver Introduction: Catalase is a common enzyme found in living and it acts as a protective mechanism for delicate biochemical machinery of cells. The enzyme catalyzes the exothermic decomposition of hydrogen peroxide to water and oxygen. 2 H2O2 → 2 H2O + O2 Hydrogen Peroxide is a by product produced by many living organisms during the process of metabolism. Hydrogen Peroxide is a very toxic substance (a power oxidizing agent) to cells and must be broken down in order to protect the cells from subsequent damage. Aim: The aim of the experiment is to investigate the effect of varying temperature has on the rate of enzyme catalyzed reaction. The focused reaction is the decomposition of hydrogen peroxide with the enzyme catalyze. The presence of catalase can be demonstrated by dropping a small piece of fresh liver tissue into dilute hydrogen peroxide solution. In this experiment, pieces of liver tissue will be put into different temperatures of water for 5 minutes. After that the liver tissues will be placed into separate solutions of hydrogen peroxide and the amount of oxygen gas produced in a minute will be measured using a gas syringe. Hypothesis: Temperature is a measurement of the degree of hotness or coldness of a body or environment. More specifically, it is a measure of kinetic energy in a sample of matter. On a molecular level, temperature is the result of motion of particles which make up a substance. As the temperature increases, the motion also increases. The motion may be due to external energy applied to the particle of internal energy from the vibration of the particle. As temperature is increased, molecules have increased active energy and reactions between them and the probability that the particles will collide with each other will also be greater, this increasing the rate of reaction. In chemical reactions, for every 10 °C rise in temperature, the rate of reaction approximately doubles. This property is known as the temperature coefficient of a chemical reaction. However in a enzyme catalyzed reaction the effect of temperature is more complex, for proteins change shape by heat. There are many factors that can affect the structure of a protein such as temperature and ph. When a protein is exposed to heat, it causes the atoms to vibrate violently, breaking and disturbing bonds within the protein, therefore changing the chemical characteristics of the protein. I hypothesize that as the temperature of the water bath that the liver tissue is exposed increases; the amount of oxygen gas liberated will also increase up. I believe that there will be an optimum temperature for the enzyme and going pass the optimum level will cause a drastic decrease in enzyme activity (less oxygen gas will be produced). Since catalase is found in almost all living things, including humans, I predict that the optimum temperature for catalase will be Variables: Independent Variable Temperature of water bath liver tissue is placed In ( °C) Dependant Variable Volume of oxygen produced in a minute (ml/min) Controlled Variable Concentration of the Hydrogen Peroxide Volume of Hydrogen Peroxide Mass of liver tissue The concentration of hydrogen peroxide must be kept constant because according to the Collision Theory proposed by Max Trautz and William Lewis in 1916 and 1918, increasing the concentration, increases the chances of particles hitting each other. The volume of hydrogen peroxide should also be kept constant. Increasing the volume of hydrogen peroxide increase the substrate concentration and thus increasing the rate of reaction. Finally the mass of liver tissue should also be kept constant to try control the amount of enzyme molecules present. Increasing the number of enzymes means there are more active sites present and substrate molecules do not have to â€Å"queue up† for access to an active site. Ultimately increasing enzyme concentration can also result in an increase in rate of reaction therefore the mass of the liver tissue should also be controlled.

Dilute with water and wash liquid. Hydrogen peroxide should be stored in a dark brown bottle and care must be taken when removing the cap as it is possible that pressure may have built up inside it. Method: Draw up a suitable table or tables to record the results. Carefully cut 7 pieces of cow liver tissue using a knife and a cutting mat. Weigh each piece of liver tissue carefully on the electric balance. Make sure each liver tissue weighs roughly around 0.5 grams. Place each liver tissue into a separate boiling tube and add 40ml of deionized water to each boiling tube once the liver tissue is situated at the bottom of the boiling tube. Place the heating mat on the table with the tripod on top of the heating mat. Gently place the gauze on the tripod. Once this is done, place the beaker on the tripod and slowly heat up the water with a Bunsen burner. Place a boiling tube with a liver tissue sample into the water and put a thermometer in the tube. Heat the beaker until liver sample solution reaches 70 °C. Measure temperature of water with a thermometer. After that, carefully measure out 100ml of hydrogen peroxide with a measuring cylinder and transfer the solution to a 250ml conical flask. Connect one end of the gas delivery tube to the gas syringe and the other to the conical flask Remove the liver tissue from the boiling tube with a pair of tweezers and place it into the conical flask with the hydrogen peroxide. Quickly cork the conical flask once the liver tissue is dropped into the solution of hydrogen peroxide. Beginning timing the time once the liver tissue touches the hydrogen peroxide solution. Stop the stop watch after 1 minute and record the amount of gas produced. Read off the gas syringe. When the reading is taken, remove the cork and dispose of the hydrogen peroxide in the chemical waste container. Repeat the above steps until data points from 10 °C to 70 °C are recorded.. For readings below 30 °C, cool the liver tissue sample with an ice bath.

The graph clearing shows that as the temperature increases, the amount of gas also increases up to 60 °C. From 60 °C onwards, the amount of oxygen gas produced decreases drastically and there is a downward slope of the curve. Discussion: From the data obtained, there is an increase of oxygen produced as the temperature of the water bath increases. This trend however only applies to the data points from 20-60 °C. At 70 °C however, there is a significant drop in the amount of oxygen gas produced and at 80 °C, the amount of oxygen gas produced is less than 5ml. From the graph, the relationship is clearly represented. Up to about 60 °C the amount of oxygen gas produced increases and ten-degree rise in temperature is accompanied by 6-7ml increases in oxygen gas produced. The amount of oxygen gas produced decrease at high temperatures as shown from 70-80 °C. So as the temperature rises, the amount of enzyme progressively decreases and the amount of gas produced is less. As a result of these two effects of heat on enzyme, there is an apparent temperature for an enzyme. Using the graph, the optimum temperature of catalase is approximately at 60 °C. The properties of a protein greatly depends on its three dimensional shape of the molecule. Exposure to heat causes the atoms to vibrate violently and this can cause bonds within the protein between different amino acid to break, resulting in a loss of the proteins biological properties. This is known as denaturation of a protein. Heating causes a proteins biological properties to change such as optical rotation, shape of active site and bonding. The active site of the enzyme is what defines the enzyme. If the active site changes, the substrate molecules will no longer fit the active site of the enzyme. This is shown in the diagram below. A proteins stability depends primary on the hydrophobic effects and to a lesser extent, by the interactions between polar residues and by other types of bonding. There are four levels of protein structure each playing a significant in the stability of the protein. The primary structure of a protein is the sequence of amino acid residues attached by peptide linkages. Proteins differ in the variety, number and the order if their constituent amino acids. Changes is just one specific amino acid in the sequence of a protein can alter a proteins property. The secondary structure of a protein develops when parts of the polypeptide chain take up a particular shape. The most common shapes are either coiling to form ÃŽ ± helixes or into ÃŽ ² sheets. The tertiary structure of a protein is the distinctive and precise structure, unique to that specific protein. This is usually the result of further folding and interactions within the molecule. The shape is held together permanently by four differ ent types of bonds: hydrogen bonding between hydroxyl and ketone functional groups, Van der Waals forces between neighboring atoms, disulphide bonds between two cysteine side chains and ionic bonds between oppositely charged ions. The stability of a protein is dependant of the balance of these three structures. Altering the balance of forces that maintains the native conformation of the protein will lead to denaturation. Conclusion: The hypothesis put forth before the experiment was correct. As the temperature of the water bath that the liver tissue is exposed increases; the amount of oxygen gas liberated will also increase up to a certain level. That level would be the optimum temperature of the enzyme and the optimum temperature of catalase deduced from the experiment is approximately 60 °C. Pass the optimum temperature, the amount of oxygen gas produced drastically decreases as the enzyme is starting to denature. At 80 °C, the enzyme is almost fully denatured and only a small amount of oxygen gas is produced. The literature value for the optimum temperature of catalase in human is about 37 °C which is the body temperature of a typical human being. The liver sample was taken from a cow and both cows and humans are able to regulate their own temperature. From this we can deduce that the optimum temperature of catalase for a cow should be roughly similar to a humans and somewhere around 37 -40 °C. The op timum temperature obtained from the experiment is 60 °C, this suggests that there may have been deviations or variations within the data. Limitation to Experiment: There are several limitations to our experiment to the experiment. One of the main limitations was controlling the temperature of the water baths. The temperature began to drop gradually once the boil tubes were placed into the beaker. This may have caused deviation and variations within the data. Another limitation was that the experiment was only repeated 3 times and there may still be room for anomalies and errors. Evaluation: As long as the temperature of the water baths were kept constant and the amount of gas produced was measured and read correctly, a good approximation of the optimum temperature of catalase in a cow can be found. However there are several key improvements that can be made. When the liver tissues were cut a lot was wasted and some of it got stuck to the spatula and to the top of the test tube. To compact the problem in the near future, the liver tissues stuck onto spatula could be washed off using a tiny amount of water or shook gently to try remove some of the liver tissue. The method for collected the oxygen gas could also have been improved. Some gas was lost due during the time it took me to insert the bung into the test tube. To minimize the amount of gas lost, have a partner put the bung on for you while you drop the liver tissue into the measuring cylinder. The temperature of the water baths started to drop after a few minutes and this may have lead to some slight deviation with in the data. In future make sure that the temperature of the water bath does not change too significantly. A slight modification would be to cover the beakers with a lid to prevent air from escaping. Another problem that arose during the experiment was keeping the temperatures of the water baths constant during tests and between trials. The problem was that different temperatures of liver samples were tested and it wouldnt be feasible to use a electronically controlled water bath to perform each test. The result was that a Bunsen burner was used but this creates several problems. It was extremely difficult to get exact temperatures and maintain them throughout the experiment. In future, the use of a heating plate would be more practical so as to prevent drastic changes in temperatures. To improve the experiment it may be better to use a solution of catalase rather than a liver as a source of catalase. By using a solution, the concentration and volume could be controlled and would be the whole experiment into a fairer test. Overall the results obtained have helped support the hypothesis put forth before the experiment. Finally the experiment could have been repeated a few more times so that a better average could be drawn from the data, resulting in a more reliable and accurate conclusion. References Clegg, C. J.

From Roswell to Dreamland :: essays papers

From Roswell to Dreamland Are we alone in the universe? This has been a common question in modern day. It is very difficult to prove that extraterrestrials exist. However, the evidence to prove that the earth has been visited is very convincing. The Roswell incident in 1947 is one event that proves the existence of extraterrestrials. Another piece of important evidence that proves the existence of UFO's is Bob Lazars testimony of his experience working in the US secret base at Area 51. The earth has been visited by intelligent life because of the witnesses and evidence behind the story of Roswell and Area 51. On July 2nd, 1947, Jim Ragsdale was camping on a three day weekend when he saw an object "as bright as a welding torch" pass through the sky and strike the ground a few miles away. Corporal E.L Pyles saw the same thing from a military compound just outside of town. Shortly after, William Brazel found strange pieces of wreckage on his massive ranch 75 miles outside of Roswell. The newspapers were already running the story Jim Ragsdale and Corporal Pyles told of the bright light in the sky, so William knew that he had found wreckage of a "flying saucer." On July 6th, he drove to Roswell with some of the debris and he showed it to the Chaves County Sheriff, George Wilcox. After examining the debris, Sheriff Wilcox contacted Major Jesse Marcel at The Roswell Army Air Field. Marcel and is commanding officer Colonel William Blanchard both inspected the debris. They both agreed that it was nothing like they had seen before, and went to the ranch to collect more of the debris. On July 8th, Marcell and Blanchard returned with two carloads of debris. The wreckage was then flown to Fort Worth Army Air Field. At noon on July 8th 1947, Blanchard ordered a press release telling the country that the army had found remains of a crashed flying saucer. Only a few hours later, General Clemence McMullen in Washington spoke by telephone with Colonel Thomas Dubose in Fort Worth, and told him to "squash" the saucer story, create a cover story, and immediately send some of the debris to Washington. Later that evening, a press conference was held in which they announced that what had crashed was a weather balloon and not a flying saucer. All of the debris, including one very large piece that appeared to still be operable, was collected and never seen again.

Use of Literary Techniques in Miltons Sonnet Essay -- Milton Sonnet

Use of Literary Techniques in Milton's Sonnet At the prime of his life, Milton was struck with blindness. As a result of this tragedy, Milton created a sonnet about his blindness. He questioned the meaning of this tragedy, of the future, and God for his blindness within the sonnet. Within Milton's sonnet about his blindness: figurative language, personification, his intent and prosody are adopted to   convey his questions and heart felt acceptance of his blindness.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Milton uses figurative language to express his grievances and discontent. He reflects upon his life and "how my light is spent," or the time he had his sight. Milton then expresses the feeling of the "dark world and wide" of the blind as his introduction to his questions. He begins to question his writing that only death can take away ("...one talent which is death to hide.."),   "lodged... useless" within him because of his new blindness. As a result, Milton begins to question God, "Doth God exact day-labour, light denied?" Milton wonders as to the meaning of his blindness; Does God want him to continue to write, even with his blindness, or what does God really mean? At first his tone seems harsh, but his feelings are redirected as he answers his own questions in time. His last question to God, was answered by himself as he realizes that he cannot blame God for his actions. His figurative language from the point he begins to question, up to where he begins to answer his own questions are full of implications of his thought. These implications must be picked out in order to make sense of the feeling and statement Milton is trying to make. ... ... He has accepted the fact that he is blind and has answered his own thoughts on God. Milton believes that he must make a choice to go on with his writing or "stand and wait," as he must bear the burden and continue or stop.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   In conclusion, Milton uses many literary techniques to express himself as he confronts his feelings with blindness within this sonnet. The uses of figurative language to introduce the dilemma and to personification for change to the solution of his problems are effectively used to contrast the mood. His prosody and intention with words creates an imaginative thought process and detail towards the sonnet. Overall, his techniques combine to convey the theme of acceptance and realization. Milton has inferred that whether or not he continues to write depends on himself and serving God.

Fast food

Fast Food Currently, most of the people depend on fast food which is easily accessible rather than cooking food at home which is a time consuming task. Fast food is the most popular food in America. Does fast food proves to be a healthy option for a daily purpose? Is fast food healthy? Being an argumentative topic this term â€Å"fast food† comes up with many questions. Fast food is a quick way of filling up your stomach but it is followed by many unknown and known disadvantages. As a peek in the â€Å"Consumers reports on fast food: four big names lose† from the book â€Å"TheNorton Field Guide to Writing†, the reporter mentions that † Next time you have a craving for fast food, think twice before slowing down for Burger King, KFC, McDonald's, or Taco Bell†. The fast food restaurants the reporter mentioned here, are the most famous and renowned places, where the consumer is attracted to eat due to food and low prices. In my opinion there is only one reason why anyone should rely on fast food couple of times and that is time saving. It saves time. But there are many other reasons as surveyed by the reporters for people to be attracted towards fast food.One major reason is the low prices. As also mentioned in the research named â€Å"Fast foods† from the â€Å"Black book† by â€Å"Emanuel Goldman- Alfred L. Simon†, that, â€Å"McDonald's might not be ready with the problems with its chicken†. But, if we see as a whole the prices of McDonald's are very low which hides the fact that there have been many issues with the chicken it use. People are attracted to McDonald's even today for their meals. There are many problems caused due to the regular intake of fast foods. Some serious problems are Obesity, weight gain, type two diabetes, coronary artery disease and PCOD.Obesity is one of the most common and erious problems found in Americans. This problem is a clear and direct result of the lifestyle in Ameri ca. The habit of substituting meals with the fast food gives a birth to obesity in an individual. In the Journal, â€Å"Fast Food: Unfriendly and Unhealthy' from â€Å"International Journal of Obesity', the author S Stender, J Dyerberg, and A Astrup has given the example of a documentary film ‘super-size me', where the character Mr. Spurlock ate McDonald's food thrice a day for 30 days and gained 11 kg.This film raises a question that whether fast food poses a special health risk. This is a very mportant question to be answered for all the fast food lovers. The other problems like PCOD and diabetes are a result of fats food intake. The Polycystic ovarian disease found in most of the women these days is caused due to the weight gain. This weight gain is a result of our food habits, like consumption of fast food on a regular basis. Another reason for the increased craving for fast food among the kids is the fast food ads which are made graphically innovative so as to attract t he kids.The recent study shown by â€Å"The Washington Post† in their program, â€Å"Trying to Cut Back on Fast Food Ads for kids†Ã¢â‚¬Ëœ mentioned that the obesity in kids of age group 6-11 has gone down because some fast food chains have cut down in their advertising. This statement shows that the advertisements and obesity in kids are directly proportional to each other. This is a strategic advertisement plan for the fast food agencies to make profit. They invest more on advertisements targeting the kids as their main audience and are women.Young women are facing many problems due to the intake of fast foods. In a Journal â€Å"Dieting Behaviors of Young Women Post-College Graduation†, the uthors â€Å"Soliah, LuAnn Walter, Janele Antosh and Deeanna†, had conducted a survey that included questions about the eating habits of women and their psychological affinity for food. The conclusion of the survey was not shocking but very obvious that three groups of women appeared to be at an increased risk of unhealthy eating and poor food selection decisions.The unhealthy food here is the fast food. Fast food is the most selling food worldwide. There are many reasons one cannot avoid the fast food. Good taste is one of the biggest reasons. Low prices are another reason which attracts the consumer. Fast food has become the regular meal of people. Whenever I visit any food chain I can see a bunch of people spending their valuable money on something which could be harmful for their health. The conclusion, henceforth, is very clear that fast food is not healthy in any terms.Fast food consumed results in many problems which are ignored by the fast food consumers. America faces most of the consequences of eating fast food on a regular basis. Some problems are very serious like obesity and diabetes which are a direct result of fast food consumption. It is still not late for the people to put a light on the articles and surveys conducted n the fas t food being a disaster and learn a lesson through their results. Fast food industries should be responsible enough to advertise less or make their food healthy instead of cheesy and greasy.An individual should keep a track on their diet decisions rationing them with their daily intake fast food and other diet. The comparison would be very useful for an individual to realize how to make their health and wealth lives longer and strong. Fast Food odBradd DentFast Food Nation Questions Introduction America’s fast food industry was founded by self made man who took risk, worked hard, some not even going to collage. Today the industry relies on a low-paid and unskilled workforce, where a handful are able to rise up the corporate ladder, while the vast majority lack fulltime employment, receive no benefits, and end up quitting after a few months. The fast food industry prospered over the last 30 years because minimum wage was lowered, marking was directed at children, federal agencies meant to protect workers and consumers ended up working for the companies, and corporations worked with congress to oppose laws that didn’t help them. The â€Å"American world view† is embodied in fast food because it takes advantage of those who don’t know any better. Chapter 1 The element of car based restaurants like the ones started in Southern California encouraged the spread of fast food because they had good food, became successful, and were very popular among young people. Chapter 2 Disney and Kroc were similar because they both used science to sell their products, made up famous mascots to sell products and both focused selling to kids. They were different because Disney founded his company, and Kroc bought his, they sold different products, and Kroc wasn’t involved in politics, while Disney was. Their companies cooperated when McDonald’s agreed to sell Disney toys and Disney agreed to allow McDonald’s in Disneyland. The fast food industry started with billboard ads to attract kids and evolved to adverting every where, from TV, to the internet, to school hallways. They also make the restaurants themselves fun for kids with play places and selling toys so they want to go more, and even as adults bring their own kids. Personally, I don’t think it is ethical to advertise in schools because it fast food is unhealthy and kids should be learning that, not that the burgers at McDonald’s get and A in taste. Chapter 3 Most employees of fast food restaurants ate teenagers because most are willing to work long hours with little pay. Fast food corporations relentlessly stop their workers from unionizing by doing things like integrating workers with information about a possible union with lie detectors, or closing locations with unions and opening new locations near by. Working conditions at fast food restaurants are unsafe. Typical dangers the employees face ate slips, fall, cuts, burns, and robberies. Problems are dealt with by increasing security with cameras or more parking lot lights. If I worked at a fast food restaurant and I injured my self, I might not tell my manager because I could loose my job because they could blame me for the injury. Chapter 4 The advantages of starting your own business is if it is successful, you could get a lot of money, not to mention you are your own boss so no one besides the government tells you how to run your business. The disadvantages are the business could be unsuccessful and you could loose a lot of money. The advantages of working for someone else are you do not have to make too many tough decisions. The disadvantages are you will not make as much money as your boss, and you may not like your boss for whatever reason. Some legal issues that fast food franchises have been involved in are the Coble’s Bill which makes franchises obey the principles other companies follow. The Subway fast food franchise was involved in the SBA which helps restaurants by giving them government funds. Subway got involved and made it so they would get extra money. Chapter 5 Family farms are disappearing because industry farms take all the business and close family farms because they have no one to sell to. there are only a few small potato farms left because industries take up all the land and business. The take-over of agricultural farms effects communities because local farms go out of business and communities become dependent on the corporate farm. Chapter 6 Development and fast food farms take land and effects cattle pastures because there is less land for the cattle to graze. Since most cowboys and ranchers have gone out of business, they have become irreverent in today’s culture. The government set up the Sherman Antitrust Act and a congressional investigation in the meet packing industry to help ranchers. Later, the Reagan administration allowed the top four meat packing firms to merge and they took over the cattle markets. Corporate domination affected family farms by forcing them to work for them or go out of business. Self-reliance is still a viable goal for Americans, but has become very difficult because of big corporations. The fast food industry makes chicken farmers work for them or they would get no business. In farm culture, the land is a tangible connection to the past, meant to be handed down and not sold. To native Americans, the land meant life and prosperity. In traditional Irish culture, the land is a link to past generations and to loose the land meant to fail your relatives. Their concept of land is similar to the American concept. Chapter 7 The demands of the fast food industry changed towns by making is so almost everyone ends up eating fast food because the industries are aloud to put their restaurants wherever they want and advertise as much as they want until the town’s economy runs on the fast food restaurants. Chapter 8 Meatpacking is dangerous because of the machines and rarely cleaned cutting tools. Since a meatpacking manager’s bonus is based in part on injury rate, many injuries go unreported and the worker is either given an easer job to takes time off to recover. Chapter 9 The meat packing and meat processing industry has been a spreader of disease because the animals are not screened well enough or sick workers spreading disease on the animals. After reading about the pathogens in hamburger meat, I am concerned about food poisoning in fast food. E. coli is not common in restaurant food, but is likely to be in hamburger meat. Chapter 10 Many Americans are obese because of lack of information and improper food laws. Fast food probably plays a big part in obesity because it provides unhealthy food to almost every where. Americans are probably more obese than other countries because fast food started here. Fast food companies increase the size of their meals to effect the calorie count look better for the per serving part. This effects American health because it is misguiding and you eat more than you thought you were going to. People in other countries do not want fast food because they have seen its effect on America. Epilogue The free market Schosser talks about leaves workers unprotected with little interference from the government. In the quote, Schosser is referring to the free market. I agree to what Schlosser says on 216. I believe the government needs to work harder to protect both the workers and consumers of fast food. At the end of the Epilogue, the author remedies his criticisms with the fact that it is a persons choice to eat want. Afterword Mad Cow disease is a disease that slowly destroys the brain and can be spread through hamburger meat. It can be controlled by feeding cows grass instead of corn and hormones, and inspecting the meat better. Cattle get infected by it because they stand in the dung of an effected cattle. It is a very serous threat to humans. Fast food Fast Food Currently, most of the people depend on fast food which is easily accessible rather than cooking food at home which is a time consuming task.
