Brine Shrimp Hatching Experiment

Brine Shrimp Hatching Experiment Wherever salt water is evaporated on a large scale, or salt lakes develop, brine shrimp will eventually appear. How do they get there? Certain birds visit salt waters   shorebirds such as gulls and stilts, for example. Could they transport the adult brine shrimp or eggs? Could brine shrimp eggs travel by wind? An interesting fact to remember is that although brine shrimp grow very well under artificial conditions, brine shrimp are not found in the open ocean. This is because the brine shrimps only defense mechanism against predators (fish and other invertebrates) is hyper-saline bodies of water. For this reason, brine shrimp have developed the most efficient osmo-regulatory system in the animal kingdom. Ask the pupils to provide an explanation of why brine shrimp are present only in salt ponds and soda lakes and not in the ocean. Use a glass container as a hatching tank for the brine shrimp, either a wide-mouth quart jar or a shallow glass pan at least two inches deep (this will work best). Fill the container with one quart of salt-water solution: mix 1 to1-1/2 teaspoons of sea salt mixture or non-iodized table salt per cup of bottled water. (If you want to use tap water, let it sit for an hour so the chlorine settles. You can also use rock or aquarium salt.) The shrimp will die in salt water that is either too weak or too strong. Sprinkle about one sixteenth of a teaspoon of brine shrimp eggs into the dish: you dont need to cover more than one square inch on the surface of the water. Leave the container in a room where bright sunlight can reach it. Your brine shrimp should start hatching in just 24 hours! The shrimp will live 1-3 days without food. If you want to keep them longer for a more in-depth study, feed them a very tiny amount of yeast a few grains as needed. You might also need to change the water occasionally, if it gets cloudy. Clean out unhatched eggs from the top of the container, which will allow more oxygen to get into the water. Observing Brine Shrimp You can study your brine shrimp close up with a magnifying glass, stereo microscope, or compound microscope. Use a pipet or medicine dropper to catch some of the shrimp and transfer them with sufficient water into a petri dish for easy observation. Look at them closely with low power (10-30x) magnification. What parts of the brine shrimp can you identify? What are their swimming habits? Eating habits? How do they use their phyllopods? How do they respond to light? If you can, compare the larval stage with the adult stage. Keep track of your observations in a notebook and include sketches of the shrimp. Learn about the effects of the surrounding conditions on brine shrimp! To start, test the pH level in the brine shrimps tank water: ideal conditions are a pH of around 8, but no lower than 5 and no higher than 10. Use pH paper for the test. To raise the pH level in the tank, add a little bit of baking soda. Discover more with a project where you change the tank environment by adding pollutants. Transfer about an equal number of brine shrimp to several petri dishes to be your test samples. Try adding 1-3 drops of a different solution to the water in each petri dish: vegetable oil, soap, vinegar, ammonia, or anything else that comes to mind. Observe the samples at low power magnification and record whats going on. How do the pollutants affect the sample? Is there a difference visible in twenty minutes? One hour? Three? How might you counteract the pollutants? You can also try hatching several batches of shrimp at a time, using different hatchery conditions for each batch. Fill 3-4 petri dishes with different solutions: you might use plain tap water, water with a low pH (acidic), and regular salt water to be the control that you can compare the results to. Before you start, hypothesize which solution will have the best results and which will have the worst. Sprinkle a small amount of eggs into each dish. After 24 hours, check on the dishes again. Has anything happened? What are the results after 48 hours? 72 hours? Use a magnifying glass for your observations, and make sketches. Were you right about which solutions would work best and worst? How do you think factors such as temperature (colder or warmer) or more or less light might affect the hatching success rate of the brine shrimp? PROBLEM STATEMENT What is the total number of successful hatching of brine shrimp? HYPOTHESIS The number of hatching is the most at the temperature of 30 à Ã‚ ¦ C. number of hatching is the lowest at 34 à Ã‚ ¦ C. VARIABLES Manipulated: temperature of incubation Responding: number of eggs hatch Fix: concentration of salt solution, number of eggs APPARATUS AND MATERIALS Brine shrimp cysts, 25ml salt, 100cm ³ dechlorinated water, 40cm ³ beaker of salt water, 100cm ³ beakers, water baths of temperature 30 à Ã‚ ¦ C and 34 à Ã‚ ¦ C, stirring rod, forceps, pipette, microscope,  ¼ saptula of eggs PROCEDURE Place 25ml of sea salt into a 100cm ³ beaker. 100cm ³ of de-chlorinated water and stir until the salt is completely dissolved. The beaker is labeled with the group name, class and the temperature in which it will be tested.  ¼ saptula of eggs is added into the beaker. Placed the beaker in incubator of temperature 30 à Ã‚ ¦ C, 34 à Ã‚ ¦ C and at room temperature. The cysts are left for one night. On the following day, the cysts is calculated. Stir the solution containing the cysts gently to make sure they are evenly distributed. 0.5 cm ³ of the solution is pipetted and put into Petri dish. Calculate the total amount of the cysts which is hatched and unhatched at all temperature under light microscope. The experiment is repeated three times to get the average value of the amount calculated. all the values calculated is multiplied by 50 to get the total amount of brine shrimp in 25ml of solution. DISCUSSION According to the tabulated data above, total cysts hatched is the highest at temperature of 30 à Ã‚ ¦ C because higher temperature is needed to make the surrounding warmer and suitable for hatching. The lowest eggs hatch being recorded is at temperature of 34 à Ã‚ ¦ C because the temperature is too high. The eggs, being the enzyme might be denatured at this point and most eggs do not hatch. There are more eggs that has not been hatch compared to those which has hatch. This might be due to the short term experiment. The eggs are allowed to soak in the solution for only a day and most of them have not hatch yet. Conducting this experiment has risen up a few conflict and ethical issue. The cysts which has and has not hatched will be thrown after the experiment end. For public, it is not ethical to kill animal which is still alive and used as a study purpose. Although they are tiny but they do play their part in food chain. They dont have right to live freely as other organism do. But, for scientists, conducting an experiment on them may bring good advantages to human. Human will get the beneficiary as new medicine and discovery is discovered without involving any human life in the research. People doesnt put too much attention when small animal like bribe shrimp is used in the experiment. LIMITATION The size of brine shrimp eggs are too small and almost impossible to be counted manually. Hence, only  ¼ spatula of the eggs are used in approximation. But there is limitation in using approximation. The number of cysts used is not the same in each test tubes makes the result. This makes the result less reliable. A larger number of cysts is needed because the results of experiment may vary and by using big group of sample, the result may be more reliable. There might be some mistakes while calculating the number of cysts that has hatched or not because the number of eggs per o.5ml is a lot and to calculate them under light microscope is almost impossible. Some students taking the number of which can be seen under lense, some takes average. The likelihood to get the real number is low. In counting the number of the eggs, the average is taken. Only 0.5ml out of 25ml is being used to be observed under the microscope. The distribution of the eggs in the solution might not be the same even after it has been stirred using glass rod. SOURCE OF ERROR The test tube which should be put under room temperature is being put in the laboratory which has air conditioner. This makes the temperature of surrounding lower than the room temperature and affect the result of experiment in making a conclusion that the earth is facing global warming. Hence, we are not sure whether or not, the room temperature has risen. Since they are too small, somehow, their hatched eggs are counted as unhatched eggs. This happens as there are no big difference in structure of the hatched and unhatched eggs. This may lead to wrong counting of the result and will affect the experiment. PRECAUTION STEP Be careful when pipetting the cysts because they are so small and might be easily get hurt. They need to be handled with care and gently. use a low light power while using microcopeas higher temperature might gives effect on the brine shrimp. CONCLUSION The hatching success of the brine shrimp is the highest at 34 à Ã‚ ¦ C

How Democratic Britian Was by the 1928? Essay

â€Å"Democracy is the government of the people, for the people, by the people† (Abraham Lincoln, President of the USA, 1860-1865)† For any country to be called democratic, certain conditions have to exist. Firstly, all adults should have the right to vote but the right to vote did not in itself make Britain democratic. Between 1850 and 1928, other features of a democracy were created. These features included a fair system of voting, a choice of who to vote for and access to information to make an informed choice. It should also be possible for people from all backgrounds to become Members of Parliament themselves and parliament should be accountable to the voters. Although the transition from a political system dominated by aristocracy to one of universal suffrage was a long and protracted one by 1928, most of the features of a democracy had been met. Consequently Britain had become more democratic than it was in 1850. It is no wonder that John Kerr describes Britain as being â€Å"nowhere near being democratic in 1850.† The state of democracy in Britain had been set by the Great Reform Act of 1832 which increased the number of men who could vote in a general election and redistributed parliamentary seats so that there was a more equal ratio of MPs to constituents. However Britain was still far from being democratic. The system was not fair as voting took place in hustings meaning there was no secret ballot, making it possible for candidates to bribe and intimidate the voters and general elections were only held every seven years. Another aspect of the British political system that was undemocratic was the unequal distribution of seats and MPs still representing county and borough constituencies with great variations in size of population. Moreover, the Tory dominated House of Lords was unelected and it could stop the elected majority of the House of Commons getting bills though parliament a nd only wealthy men could stand as candidates for election as there was a property qualification. It could be suggested that Britain was undemocratic in 1850 as working class men and all women were excluded from the franchise and only 7% of the population were entitled to vote. Between 1850 and 1928 a series of acts were introduced that extended the franchise. The Second Parliamentary Reform Act of 1867 was the first piece of legislation that tried to amend the political system. As a result of this Act, the size of the electorate increase to 2.5 million including the skilled working class meaning a third of males were now able to vote. However, the vote still depended on property and the one year residency requirement discriminated against a large proportion of the working class. The introduction of the Representation of the People Act in 1884 doubled the electorate making the number of voters five million and the franchise qualification was now the same in both boroughs and counties. Although Sir Albert Maine described the new system as an â€Å"unmoderated democracy† there was still a long way to go until Britain became democratic. The men who did not have the franchise in 1867 such as the soldiers and male domestic servants were still deprived of the vote in 1884 and as with 1867 plural voting still existed and no women were allowed to vote. The Representation of the People Act 1918 extended the franchise to all adult males because of their important role in the Great War meaning that all males over the age of twenty one were now enfranchised. For the first time, women over the age of 30 were given the vote provided they were educated, married and had a home. Although this was a major step towards democracy as regards women’s suffrage, it mus t be noted that there was not equal universal suffrage, and that women would have to wait until the 1928 Equal Franchise Act to be set on equal voting terms as men without qualifications, to receive the vote at the age of 21. As a result of the increase in voters in towns, changes were made to National Party Organisation as party leaders had to find ways of persuading the electors to vote for their candidate. National organisations such as the Conservative Central Office in 1870 and the National Liberal Federation in 1877, were developed by the parties to canvass support at elections. Liberal and Conservative Associations were developed in all major towns and electors were encouraged to join and attend meetings. Liberal and Conservative clubs were set up as social centres to encourage support such as the Reform Club in Manchester and the Carlton Club. This led to more central co-ordination of policy and strategy. Propaganda and persuasion would be the means of enlisting the support of the voters and the parties had to ensure that their known supporters were registered as voters. The Conservative Primrose League was created to canvass support in small towns and the counties. Tighter discipline was imposed in both parties and the result was a development of political parties and their organisations. Overall, better representation helped the growth of democracy as well as better access to information as manifestos had to be created and distributed to the population. The 1970 Education Act (1872 in Scotland) increased the literacy levels in the country so that information about political parties and their policies became more accessible to the population. By the late 19th century literacy was fairly well established and daily national newspapers became vital sources of information. The development of the railways was crucial in giving the population better access to information. The population was able to make more informed choices in elections as they became more aware of political issues. Socialist groups eventually joined with the Trade Union movement to form the Labour Representation Committee in 1900 which in 1906, became the Labour Party- a party that claimed to represent the working class. This meant that the electorate had a genuine choice of parties with different political ideologies: the Conservatives, Liberals and the Labour Party. Consequently, this pushed Britain forward towards democracy as different can different parties can voice different views on how to deal with the problems the country faces. Although Britain had become more democratic with better access to information and a choice of parties certain aspects of the system were unfair until legislation was introduced to improve this. The Reform Act of 1867 improved the distribution of seats making the system fairer in addition to extending the franchise. The facts show that many small boroughs lost one or even both of their MPs who were then redistributed to areas of the country that were under-represented. For example, Scottish constituencies were allocated 5 seats. However, democracy was still far from being reached in Britain as MPs were still not evenly distributed, the electorate largely remained the same and balance of political power was not altered. The Redistribution of Seats Act of 1885 moved Britain closer towards democracy as it aimed to construct constituencies of equal size to have a fairer representation of the people. As result of the Act, 79 towns with a population of under 15,000 lost both their seats and the total number of MPs was increased from 652 to 670. In fact, in his book â€Å"The extension of the Franchise 1832-1931† puts forward his opinion: â€Å"together, the 1884 Franchise Act and the 1885 Redistribution Act brought about one of the most radical changes in the parliamentary election system during the nineteenth century. Bribery and corruption were still present in elections in the late 1860s and two laws were passed in an effort to eliminate this. The Secret Ballot Act of 1872 allowed voting to be done in secret so electorates were free from intimidation. It meant that the newly enfranchised working class would not be pressurized into voting for their landlords in fear of losing their home or jobs. The secret ballot was an improvement in Britain towards democracy and the Chief Commissioner of Police in London reported there had been no trouble at the elections. However, employers were still bribing their workers and between 1867 and 1885 four towns were disenfranchised due to corrupt practices. Moreover, an opponent of the Act Lord John Russell, argued it would undermine the â€Å"legitimate influence of the aristocracy, over people who looked to them for leadership†. Many believed that it was you duty to tell people how you voted, it was considered† honest and British† and there was a belief that secrecy would lead to further corruption. The Corrupt and Illegal Practices Act was introduced in 1883 and it meant that if there was any corruption in any election it would lead to a heavy fine or imprisonment. There was less intimidation; the new code of ethics had moved Britain forward towards democracy. S.Wood said that â€Å"elections certainly became more orderly†. Despite these steps towards democracy, plural voting still existed and MPS were still not paid. Even though the property qualification for MPs was abolished in 1857 meaning that ownership of land was no longer a prerequisite for becoming an MP but one issue that still had to be resolved was the payment of MPs. This made the Parliament Act of 1911 a â€Å"great achievement† according to Stephen J. Lee as MPs finally got a salary of  £400, meaning that anyone could stand as an MP, whether they are working, middle or upper class. However, in reality working class men could not afford to give up their day job to become a politician so very few working class men stood as candidates. In addition, the Act reduced the life of the government from seven years to five years .The House of Lords which Lloyd George described as â€Å"five hundred men, ordinary men chosen accidentally from among the unemployed,† no longer had power over bills to do with taxation or government spending and could only delay bills for up to two years. Despite the fact this made the elected house more accountable to the voters, Britain was still not fully democratic as the House of Lords still had some power despite being an unelected body. Although Britain had made strides towards democratic by 1928 there were still other factors that were undemocratic such as universities still having Seats in Parliament until 1949 and the franchise was not being given to 18 year olds until 1969.Moreover, elections in Britain use the First Past the Post System meaning the person with the most votes wins the election. However this could be seen as being unfair in that the percentage of seats the larger parties end up with in Parliament is always greater than the percentage of votes they have achieved in the election. For example, in the 2005 General Election although the Labour Party got 36.2% of the votes, they had 55% of the Seats in Parliament. For many years, smaller parties like the Liberals gave argued for a system of Proportional Representation which makes the proportion of seats a party has equal to the percentage of votes the party got in the election. First Past the Post was confirmed as the voting system for general elections in the United Kingdom in 1918 and this has not changed since. By 1928, Britain had become a more democratic country as all the features that would be expected in a democracy were in place such as universal suffrage, the secret ballot and better representation. There was a choice for voters of different backgrounds of three main political parties and working class candidates were able to stand for election as MPs were paid. Furthermore, access to information was greater than it had been in 1850. However, 18 year olds were not given the vote until 1969 and the electoral system is still an issue today as many people argue that Proportional Representation should be used in British elections.

PESO Online Job Posting System Essay

INTRODUCTION Today, we are living in a modern age engaged in highly computerized technology where computer devices manifest everywhere aiming to enhance individual lifestyle and most especially in the world of business. Manual operations are considered out of date and are left behind because of modern technology. Using computers and modern technology is a great help to every individual most especially to business transaction. Individuals and companies today wants manual operations to be replace with an automated one in order for them to have a better and easy lifestyle and operations. But today, many companies even local government offices are using manual operations that consume a lot of time, money and effort that gives every individual and companies a hard time. As modern technology continues to improve, all processes are automated and are moved onto the web or cloud based. The online job posting system replace the manual operation of the office regarding the posting of jobs, referral and screening of applicants, recording and creation of reports and information and screening and communication with companies. Online job posting will improve the office services and provides convenience on the applicants, employers and office staff. EXECUTIVE SUMMARY The Public Employment Service Office or PESO is a multi-service facility that was established to provide information and assistance to DOLE clients and constituents of local government units (LGU’s). It makes available under one roof the various employment programs and services of the Department of Labor and Employment (DOLE) to enable all types of clientele to know more about them and to provide assistance on employment and income opportunities or other specific assistance needed. It’s services are to provide job fairs, livelihood and self-employment bazaars, Special Credit Assistance for Placed Overseas Workers, Special Program for Employment of Students and Out-of-School Youth, Work Appreciation Program, Workers Hiring for  Infrastructure Projects and Other programs/activities developed by DOLE to enhance provision of employment assistance to PESO clients HISTORY This study focuses on the ordering process in Public Employment Service Office. The Public Employment Service Office or PESO is a non-fee charging multi-employment service facility or entity established or accredited pursuant to Republic Act No. 8759 otherwise known as the PESO Act of 1999. The Republic Act No. 8759 was signed in to law on February 14, 1999. Its purpose is to carry out full employment and equality of employment opportunities. Duties: 1. Ensure the prompt, timely and efficient delivery of employment service and provision of information on the other DOLE programs. 2. Provide a venue where people could explore simultaneously various employment options and actually seek assistance they prefer. 3. Serve as referral and information center for the various services and programs of DOLE and other government agencies present in the area. 4. Provide clients with adequate information on employment and labor market situation in the area. 5. Network with other PESOs within the region on employment for job exchange purposes. Functions: 1. Encourage employers to submit to the PESO on a regular basis a list of job vacancies in their respective establishments in order to facilitate the exchange of labor market information services to job seekers and employers by providing employment services to job seeker, both for local and overseas employment, and recruitment assistance to employers. 2. Develop and  administer testing and evaluation instruments for effective job selection, training and counseling. 3. Provide persons with entrepreneurship qualities access to the various livelihood and self-employment programs offered by both government and non-governmental organizations at the provincial/city/municipal/barangay levels by undertaking referrals for such program. 4. Undertake employability enhancement trainings/seminar for jobseekers as well as those would like to change career or enhance their employability. This function is presently supervised by TESDA and conducted by other training. 5. Provide employment and occu pational counseling, career guidance, mass motivation and values development activities. 6. Conduct pre-employment counseling and orientation to prospective local and overseas workers. 7. Provide reintegration assistance services to returning Filipino migrant workers. 8. Perform such functions as willfully carry out the objectives of this Act. ORGANIZATIONAL CHART Figure 1: PESO Organization Chart RESEARCH LOCALE Figure 2: PESO Location Map PROBLEM DEFINITION Currently, the Public Employment Service Office at San Jose Del Monte Bulacan is using a manual operation in posting of jobs, referral and screening of applicants, recording and creation of reports and information and screening and communication with companies. Companies having a hard time on submitting reports about the applicants they hire because of the manual operation, thus, the PESO staff are also having a hard time creating reports.  Inconvenience, the applicants need to go to the office from time to time for them to know what jobs are available. And the companies must send a  representative to communicate and present the needed requirements before they can become a qualified employer for PESO. The problems stated above will all be solved using the proposed system which is the Online Job Posting System. OBJECTIVES OF STUDY Generally this study aims to solve issues that happened in the manual operations in Public Employment Service Office. The study is conducted to find out if minimizing the manual operations with an online job posting system could help Public Employment Service Office customers to achieve quality ordering service. Specifically, it aims to; Identify the key issues relating to the development of an online job posting system and understand the flow posting of jobs, referral and screening of applicants, recording and creation of reports and information and screening and communication with companies. Identify the problem that the staffs, employers and applicants encountered in the existing manual operations of PESO Provide a solution for the identified problem. SCOPES AND LIMITATION . The system which is job posting system will be implemented for the Public Employment Service Office. The system will be used by the staffs, employers, and applicants. The system will allow the applicants to browse jobs and be notified to new qualified jobs. It will also make the registrations of the applicants easy by not needing for them to go to the office. It will also benefit the employers, they will be no longer need to go the office just to communicate and give requirements. It will also make the creation of reports easy on the part of staffs and employers. On the other hand, the system limitations are, only citizens of San Jose Del Monte Bulacan can register online; citizens of other city are required to go to the office of PESO of CSJDM for special cases. The said system cannot be used when there is power shortage and can only be used if there is an internet connection. Notifications through SMS are limited to those who provide their contact information and to those who have a good network signal. PROJECT DESCRIPTION Figure 3: Project Sytem Logo SIGNIFICANCE OF STUDY The study will help the PESO to improve and speed up their services. The developed system will greatly improve the processes and replace the manual operations with a more organized and automated processes. It will give benefit the staffs, employers and applicants. Staffs- the proposed system will help the staffs to provide a more reliable and easy to do reports and records, more effective and efficient way of job posting, easier way of screening, giving referrals, communicating with applicants and employers and will eliminate human errors..

Energy Management in Thermal Power Plants - 895 Words

ENERGY MANAGEMENT IN THERMAL POWER PLANT INTRODUCTION Thermal Power Plants are the most important source of power generation. They are based on the Rankine Cycle where high pressure and high temperature steam raised in a boiler is expanded through a steam turbine that drives an electric generator. In a thermal power plant, the chemical energy stored in fossil fuels such as coal, fuel oil, natural gas is converted successively into thermal energy, mechanical energy and finally electrical energy for continuous use and distribution across a wide geographic area. Thermal Power plants have very high availability. Their unplanned or forced outage rates are very low. Thermal Power Plant assets need to be flexible to meet rapidly fluctuating†¦show more content†¦RECENT CONCEPTS Some of the recent concepts are directed at the development of advanced technologies and knowledge products that can enhance the environmental performance of the existing fleet of coal-fired power plants. The overall goal of these efforts is to reduce the amount of freshwater needed for power plant operations and to minimize potential impacts on water quality and increase in reliability due to better control of the operation by providing instrumentation of the latest design. The program is built around four specific areas of research: †¢ Non-Traditional Sources of Process and Cooling Water †¢ Innovative Water Reuse and Recovery †¢ Advanced Cooling Technology †¢ Advanced Water Treatment and Detection Technology Non-Traditional sources of Process and Cooling water: Research and analysis are being conducted to evaluate and develop cost-effective approaches to using non-traditional sources of water to supplement or replace freshwater for cooling and thermal power plant needs. Examples include surface and underground mine pool water, geological carbon sequestration and coal-bed methane produced waters, and industrial and/or municipal wastewater. This will help save freshwater. Innovative water Reuse and Recovery: Research is currentlyShow MoreRelatedNational Thermal Power Corporation Ltd Essay1544 Words   |  7 Pages1.
