Aqua Silencer Essay

This project is an attempt to reduce the toxic content of diesel exhaust, before it is emitted to the atmosphere. This system can be safely used for diesel power packs which could be used in inflammable atmospheres, such as refineries, chemicals processing industries, open cost mines and other confined areas, which demands the need for diesel power packs. WORKING PRINCIPLE The aqua silencer is more effective in the reduction of emission gases from the engine exhaust gas using perforated tube. By using perforated tube the back Pressure. Will remain constant and the sound level is reduced. Using the perforated tube the fuel consumption remains same as conventional system. By using water as a medium the sound can be lowered and also by using activated charcoal in water. We can control the exhaust emission to a grater level. The water contamination is found to be negligible in aqua silencer, because the amount of acidity level in aqua silencer is expected to be below the dangerous acidity. It is smokeless and pollution free emission and also very cheap. The aqua silencer’s performance is almost equivalent to the conventional silencer. ADVANTAGES Diesel engines are playing a vital role in Road and sea transport, Agriculture, mining and many other industries. Considering the available fuel resources and the present technological development, Diesel fuel is evidently indispensable In general, the consumption of fuel is an index for finding out the economic strength of any country.

Effects of Temperature on Catalase

QUEENSLAND ACADEMY FOR HEALTH SCIENCES INTERNATIONAL BACCALAUREATE Term 1 2013 SUBJECT: BIOLOGY YEAR 11 HL & SL Name of Student: Name of Teacher: FORMATIVE ASSESSMENT ITEM: Chemistry of Life Practical Investigation Term 1 Task: Investigation of a Factor Affecting Enzyme ActionAspects Assessed: D DCP CE MS Introduction:Thousands of enzymes are found in living cells. In addition to making life possible, many enzymes have numerous applications that affect our daily lives in other ways such as food processing, clinical diagnoses, sewage treatment, and the textile industry.In this activity you will investigate how a particular factor influences the action of an enzyme. Conditions: Students are NOT required to design an experiment. Experimental design has been provided for you to use instead. You are however required to submit a Risk Assessment for the investigation. Students are to work independently. However, you will need to collect raw data from 4 other students to make the 6 trials. T he final version is to be submitted to TURNITIN and then class teacher. A journal will need to be included as part of the final submission.Time Allowed: 4 weeksDue Dates Task Out first lesson week1, term 1, 2013Risk Ass Due: last Lesson week 2, Term 1, 2013Final: First lesson week 6, Term 1, 2013Procedure: Your task is to investigate the effect of temperature on the activity of enzyme catalase found in beef liver. Use the experimental design and the BioLab Guide provided to assist with your report write up.Safety Considerations:You must have the risk assessment checked before continuing. NOTE: For this task you are required to submit a journal which documents your progress. You are also required to include photographs which display the techniques you used in the experimental procedures. This evidence will be used in assessing your manipulative skills in this experiment| RESULTS: REFER TO the Assessment Grading Matrix| Effect of temperature on the activity of Catalase Design Aspect 1: Research QuestionThis lab will be driven by the research question, Do changes in temperature (from 0? C, 7? C, 19? C, 37? C, and 100? C) have an effect on the activity of the enzyme catalase (found in beef liver) in the breakdown of hydrogen peroxide? Hypothesis If liver is placed in different temperatures of 0? C, 7? C, 19? C, 37? C, and 100? C and hydrogen peroxide is added to each piece of liver, then the liver placed in 37? C will have the largest reaction height. The liver in 100? C will have the smallest reaction height, followed by the liver in 0? C, then 7? C, and then 19?C. Introduction Pearson Baccalaureate: Standard Level Biology Developed Specifically for the IB Diploma defines enzymes as â€Å"protein molecules which act as catalysts for reactions. As catalysts, the real function of enzymes is to lower the activation energy of the reactions that they catalyze† (166). Enzymes are proteins; therefore the liver has a particularly high concentration of catalase. W hen hydrogen peroxide (H2O2) is added to liver, catalase catalyzes a reaction in which the hydrogen peroxide is broken down into oxygen gas (O2) and liquid water (H2O).Hydrogen peroxide is a toxic chemical that is produced as a byproduct of many normal cellular reactions, so it is crucial that catalase in the liver breaks the hydrogen peroxide down into the two harmless substances of oxygen gas and liquid water. The hydrogen peroxide must be quickly degraded or converted, and catalase accomplishes this task because one molecule of catalase can deal with six million molecules of hydrogen peroxide in one minute. Enzymes and the temperature of their environment are particularly important to the human ody because â€Å"Many of the reactions which represent the digestive process would need far higher temperatures than we are able to maintain safely if enzymes were not involved† (166). The prediction in the hypothesis is based on the concept of denaturation. As Pearson Baccalaureat e: Standard Level Biology Developed Specifically for the IB Diploma states, â€Å"Reactions which use enzymes do have an upper limit. That limit is based on the temperature at which the enzyme (as a protein) begins to lose its three-dimensional shape due to intramolecular bonds being stressed and broken.When an enzyme loses it shape, including the shape of the active site, it is said to be denatured† (75). Due to denaturation, the liver placed in 100? C will have the smallest reaction height because at this temperature catalase will begin to denature. Because â€Å"reactions with or without enzymes will increase their reaction rate as temperature (and thus molecular motion) increases†, the liver placed in 0? C, 7? C, and 19? C will have small reaction heights, but the heights will increase as temperature increases (75). The liver placed in 37?C will have the greatest reaction height because â€Å"human catalase works at an optimum temperature of 37? C, which is approx imately the temperature of the human body†. Although this lab is using beef liver instead of a human liver, the optimum temperature for beef liver should be similar to that of humans. The predictive graph on the previous page represents how as the temperature of beef liver originally increases, the height of the reaction increases as well due to an increase in molecular collisions. At a certain temperature, the catalase will reach its optimum temperature and have the greatest height of reaction.However, as the temperature continues to increase the enzyme will begin to lose its shape and denature, so the height of the reaction will decrease. This lab will be using beef liver, which contains the specific enzyme catalase, and by placing the liver into different temperatures it will be assessed how catalase performs under certain conditions. After the liver has been placed in different temperatures, hydrogen peroxide will be added to each piece of liver, and by measuring the heigh t of the chemical reaction it will be determined which temperatures catalase performs the best in.Reactions with a high height will represent catalase quickly and efficiently breaking down the hydrogen peroxide, and reactions with a low height will represent catalase slowly and inefficiently breaking down the hydrogen peroxide. This lab will serve as a model for the role of enzymes in the human body, and will outline the importance of enzymes for the human body. Independent Variables The independent variable is the temperature of the liver, and it will be measured in ? C. The different temperatures used will be 0? C, 7? C, 19? C, 37? C, and 100? C. Dependent VariablesThe dependent variable is the height of the reaction, and the bubbles of gas produced will be measured in millimetres (mm). Control Variables Table 1: Control variables and their treatments Variable | Effect | Control | Size of liver | Could increase or decrease the height of the reaction. A larger piece of liver means more catalase, which could break down the H2O2 at a more efficient rate than smaller pieces of liver. | Cut every piece of liver the same size by weighing each piece on an electric beam balance. Each piece of liver is approximately 1. 4g. pH | pH has an effect on enzymes and each enzyme has an optimal pH. By making the liver more acidic, basic, or neutral the height of the reaction could increase or decrease as it deviates from its optimal pH. | Do not change the pH of any of the solutions. This lab is only investigating the effect of temperature on enzyme activity, not the effect of pH on enzyme activity, so nothing should be added to the liver that would increase or decrease the pH. | Time | If some pieces of liver are kept in their specific temperatures longer than others, the height of the reaction could be greatly affected.By keeping the liver in its temperature for a shorter period of time, the liver itself has less time to change temperature which could greatly alter the resu lts. | Keep all of the pieces of liver in their specified temperatures for five minutes. | Size of test tube| Different sized test tubes will hold different volumes of O2 and will give incorrect measurements with the ruler| Keep all the test tubes the same size – with volume of 30cm3| Uncontrolled Variables The variables that will be difficult to control include air pressure in the lab and the volume of the liver.Measures will be taken to reduce the effect of these on the experiment by keeping air conditioning at 24? C and cutting the liver close to the same shape and size. Control Experiment The control experiment for this investigation will be the experimental setup at 0? C. All the steps in the method will be followed at this temperature. At 0? C the experiment should not proceed as the energy needed for enzyme action is unavailable.

Repeat this for all 10 test tubes, and record the measurements in your data table. 15. Pour the liver from each test tube into a waste beaker, clean each of the test tubes out, and put all materials away. 16. Combine the data that your own group obtained with the data from two other groups.This will allow for six trials worth of data, and once you obtain this sufficient amount of data, calculate the average height of the reaction for each of the five temperatures over the six trials, and then calculate the standard deviation for each of the five temperatures over the six trials as well. Variable | Unit of Precision | Error/Unc ertainty | Temperature | ? C | +/- 0. 5? C | Height | mm | +/- 0. 5mm | In the procedure, the maximum height of the reaction will be determined by marking the position of the tallest bubble that results from the reaction.

By viewing the average height of the reaction, these results are supported/rejected. The liver placed in 37 °C had an average reaction height of (state) mm, (also state the average reaction heights of the other experimental setups). This data coincides/differs with the predictions stated in the hypothesis, where I stated â€Å"The liver in 100?C (complete). † By observing the constructed graph in Introduction, it is clear that the average height of the reaction initially increased as the temperature increased, but when temperatures increased past optimum (37 °C), (complete). Graph 1 constructed from the obtained data shows (discuss Graph 1). Graph 2 shows (discuss Graph 2). These results outline the effect of temperature on enzyme activity, and it is apparent that changes in temperature do/do not have an effect on the enzyme catalase. Conclusion ExplanationThe results obtained give increased insight into the role of enzymes in the human body. The beef live r closely modelled the human liver, and it is clear that catalase works best at an optimum temperature of (state). This is important because humans maintain a stable body temperature of (state), and with the aid of enzymes this temperature provides enough activation energy for metabolic reactions, in this case the breakdown of hydrogen peroxide into oxygen gas and liquid water. (Discuss why the liver placed in lower temperatures and 100 °C did not react well.Remember to cite the references used correctly). CE Aspect 2: Evaluation: Reliability While the results obtained from this lab clearly support/reject my hypothesis, the examination of the calculated standard deviation for each temperature (discuss STDEV). This range in standard deviation is due to errors that may have occurred throughout the lab. The liver placed in 0? C had a standard deviation of (sate), the liver placed in (discuss other STDEV’s). The larger the standard deviation, the less/more reliable the data. Al so discuss error bars and number of trials. Note: larger error bars = less reliable data; more trials = more reliable data). Errors/Limitations in Experimental procedure List as many errors you think may have occurred in the experimentation – from measurement as the reaction was slow, to timing, to others you can think of (preferably 5). Discuss how each of the errors could have affected your data. Significance Write a paragraph on how much the errors listed above could have impacted on your experiment’s reliability. CE Aspect 3: Suggestions for Improvements:For each of the errors mentioned above (about 5) suggest what can be done to improve this experiment in the future. Also state how these improvements will help. References Damon, Alan, Randy McGonegal, Patricia Tosto, and William Ward.

Illegal Immigration can be curbed by enforcing existing immigration Essay

Illegal Immigration can be curbed by enforcing existing immigration laws, repealing birthright citizenship, and requiring proof - Essay Example In the decades that followed, the number of immigrants entered USA presented a trend of continuous increase; in 1977, 1 million immigrants from Mexico entered USA (Reed 25). It is clear that appropriate measures need to be developed towards the elimination of illegal immigration across the country. These measures should not be considered as an opposition to human rights but rather as an effort to secure the quality of life of citizens. Moreover, appropriate criteria should be used for judging the provision to immigrants of American citizenship. The measures taken for the control of illegal immigration across USA would include the introduction of mechanisms for enforcing existing immigration laws (especially ‘the Personal Responsibility and Work Opportunity Act of 1996 and the Illegal Immigration Reform and Immigrant Responsibility Act of 1996’ (Koven & Gotzke 142)), the repealing of birthright citizenship and the provision of right to apply for social services only to th ose who can prove their citizenship. The above issues are discussed in this paper referring to the literature that has been published in this field. It is assumed that the plans promoted in USA for the control of illegal immigration are important but they are not appropriately monitored; as a result, these plans often fail to address effectively the specific problem. It is assumed that it is not a problem related to the lack of legislation but rather to the lack of effective cooperation among the authorities involved in the relevant processes. In accordance with Anderson (2010) the control of illegal immigration in USA has been proved to be quite difficult; in the context of the above finding, authorities in USA have tried to focus on those forms of immigration that would be easier controlled – reference is made to the legal immigration (Anderson 215). For this reason, the measures developed for the control of illegal immigration in USA may affect legal immigrants also, a pro blem, which needs to be appropriately addressed; however, the above problem should not prohibit the authorities from enforcing the current immigration laws, as such practice would benefit the illegal immigrants across the country. At this point, the following issue needs to be highlighted: under certain terms, immigration laws are not enforced in US because of the existence of a series of interests depended on illegal immigration; the most indicative example of such case is the entrance of illegal immigrants in the workplace. Illegal immigrants cannot ask for normal wage – in terms of its level; in fact, their wage is lower compared to the average wage of employees in a similar job position. As a result, employers prefer illegal immigrants, a fact that makes the entrance in the workplace for citizens and legal immigrants even more difficult (Weissinger 203). The above phenomenon is so extended that the enforcement of immigration laws across the country has become quite proble matic. However, no signs seem to exist regarding the limitation of the above problem. In fact, in a relevant research it has been revealed that the immigration agents across USA are about 2,000 – while the illegal immigrants in USA have been estimated to 11.5 million (Gaines & Miller 124). In accordance with Wepman (2007) the lack of effective enforcement of immigration laws in USA leads to the following assumption: existing illegal immigrants across the country ‘face little or no risk of removal once they entry the country’

African american racial status in the 21st century Essay

African american racial status in the 21st century - Essay Example Racism has been a curse for the American society from its birth in 1751. It has stained the nation’s identity with the African-American’s blood for years until the Civil War in **** and the 13th Amendment. Though the 13th Amendment in the US constitution was a resistive response of the most progressive and conscientious part of the US society to the barbaric practice of slavery, slavery had not been wiped out from the society overnight. Racism was so much deep rooted in an American’s heart that the enactments of anti-slavery laws and the relevant amendments in the US Constitution were merely to redirect a racial mind to find alternatives for white superiority over the Black. Indeed the amended Constitution provided the legal safeguard to the Black, barring the practice of slavery at the state level as well as, to the extent the state could interfere into the public affairs. But it could do nothing to bring about the changes in the culture and the society that int rinsically nourished the racial hostility against their former slaves. The inbred racism in the Americans’ heart continues to discriminate between the White and the Black until today. Therefore the 14th and 15th Amendment with along with numerous other subsidiary laws and government-induced initiatives has been required to wipe out the remainders of racism from the American society. But the question whether racism and discrimination against the African-American black have been wiped out from the society may engender a lot of debates since the question itself is ambiguous. Inbred Racism and Racism in the Heart of America A close analysis of the status of racism in American society in the late 20th century and the 21st century will reveal that America has been significantly successful in wiping out the all the institutional and constitutional racisms. But non-formal and non-institutional racisms still are prevailing in the society. In this regard, Saeed Shahbaazz says, â€Å"A CNN/Opinion Research Corp. poll, released in December 2006, stated that most Americans, White and Black, see racism as a lingering problem in the United States.† (1).

In their article, â€Å"â€Å"A Fly in the Buttermilk†: Descriptions of University Life by Successful Black Undergraduate Students at a Predominately White Southeastern Universityâ₠¬  Davis et al explores deep into the self-realization -from the student’s perspective- of a non-white minority student about his or her position among the white majority. The title of their study explicitly asserts the concerns of the Successful Black Undergraduate Students with their University Life among white majority. The researchers prudently selected 11 black students as the participants of their study. Davis et al’s purposed selection of the successful participants can be justified on the pointed that information and experiences provided by the participants would remain free of any fear of being discriminated. The participants were chosen ensuring the following conditions: a. successful students were chosen, because they experienced the full, 2. successful students would be free of being the victim of racial discrimination academically, 3. these students would be able to track any change during their four or five years graduation. Devis et al’s research shows that even in the 21st centur
