My ambitions in life Essay Example for Free

My ambitions in life Essay My name is Jennis Dave Mirafuentes, I am now 16 years old. Were all 5 children in my father side, why I say in my father side only? It is because my father before was having his first family but they were separated because of some instances. We have 3 girls that is daughter of my father in his first wife and we are 2 in my mother side and we are both boys. We are now living in Km. 8 Ulas, Davao City. I finnish my primary study in Talomo Central Elementary School and my secondary in Talomo National High School. My first ambition in life when I was only a child is to become an architect because I love making an illustration of an house before but it was changed when I grow up because I realize that having an architecture course is difficult. When I was in my fourth year in high school I was still thinking of what course I will take in college. And from that time I realize in myself what if I will follow the steps of my mother. I will continue her job in teaching other people because before my mother was graduated of education and she is also a board passer but when the time that she raise me and my younger brother she doesn’t have enough time in teaching so that she decide to stop teaching and focus in caring of us. That’s why I decided to become a BS-Math student, Math because it was my favorite subject. Why I should become a teacher? Maybe now I still don’t have an ability to teach wisely other people but I didn’t refuse my ambition because the reason I studied is to learn the techniques on how to become an effective teacher. Maybe now I was only holding one quality to become a teacher and that is my determination and willingness to teach.

Indo-US civilian nuclear deal

Indo-US civilian nuclear deal INDIAS ENERGY SECURITY WITH SPECIALREFERENCE TO INDO-US NUCLEAR DEAL â€Å"Consider the past 400 years of history. The world developed a new source of power, steam, and the industrial age came in. India with all her many virtues did not develop that source of power and it became a backward and a slave country. Now, we are on the verge of the atomic age. If we are to remain abreast in the world as a nation which keeps ahead of things, we must develop this atomic energy quite apart from war†¦of course, if we are compelled as a nation to use it for other purposes, no pious sentiments of any one of us can stop the nation from using it that way.† Jawaharlal Nehru, 06 April 1948 CHAPTER I INTRODUCTION AND METHODOLOGY The energy security encompasses the oil natural gas, fuel and electricity. However in the backdrop of Indo-US civilian nuclear deal we are referring to the electrical energy security generated from nuclear sources. The Indias nuclear reactors are fueled by uranium. Indias uranium is low grade and quantity and is about seven times costlier than whats available in the world market. The Indo US civilian nuclear deal encompasses the transfer of sensitive technology for reprocessing, enrichment of fuel and importing uranium for generation of electricity from nuclear energy. In recent years, if there is one issue that has been on the headlines at regular intervals besides terrorist attacks in different parts of our country, is the Indo-US civilian nuclear deal. So much so that it was on the verge of bringing down the worlds largest democracy. Never before in the history of independent India where any subject thought about, deliberated, argued and counter argued by the political, bureaucr atic and the scientific elites. The main advantage of this deal is that the India not only got the assurance from the world to increase its electricity generating capacity but India can continue its nuclear weapon programme unhindered. The deal also gave strategic advantages to US. METHODOLOGY Statement of Problem 2. This paper aims to analyse â€Å"Will India be able to fulfill its power demand by 2030 by generating electricity from nuclear power plants in light of Indo-US civilian nuclear deal.† Hypothesis 3. The extent of Indias strategic interest has expanded and span from the Gulf of Hormuze up to the Malacca Strait. It implies that India is on the threshold of becoming a regional super power, having a large say in the geopolitical affairs in South Asia. This situation has come about as a result of the economic liberalisation in last decade of the twentieth century, causing the economy to grow at appreciable rates of 7-8 % per year. Economic opportunities in India have made the world sit up and take notice, causing a huge influx of investments in all business and industrial sectors. 4. Given the above situation, Indias electrical energy needs are growing by leaps and bounds, and at a very rapid pace. The sources for generation of electricity to support this unprecedented growth are not adequate. Therefore, it is imperative that India must look for alternative sources to generate sufficient electricity not only to cater for future growth but also to bridge the gap between the demand and supply. This will also help India for realisation of her role as a regional power to satisfy her strategic aspirations. Justification of the Study 5. India is concern for energy security in general and electrical energy in particular for its economic development and uplifting the standard of living of its citizen. Indo-us civilian nuclear deal is a step towards to solve Indias energy problem which encompasses the generation of electricity from nuclear energy and transfer of sensitive technology including supply of raw material. But the deal has more strategic and international connotation. If we adopt the perspective of twenty years hence, will India be able to achieve its energy security? Scope 6. The scope of this study would be to look into Indias electric energy requirement by 2030, highlighting the electricity generating capacity and gap between demand and supply. Also to analyze the nuclear power plants generating capacity in a backdrop of Indo-US civilian nuclear deal with its strategic implications for India. The study would also suggest a way ahead for India to achieve total energy security. Other related issues such as electrification, transmission, distribution, billing, electrical energy conservation and regulatory commissions are not considered in this study. Operational Definitions 7. Energy Security.[1] A countrys ability to optimize its energy resource portfolio and supply of energy services for the desired level of services that will sustain economic growth and poverty reduction. It is a broad umbrella covers all type of energy and economic growth. 8. Nuclear Energy and Energy Security.[2] Nuclear Energy is the kinetic energy of the fragments that result from the fissioning or splitting of uranium and plutonium nuclei when they absorb neutrons. The kinetic energy is converted to heat as the fragments are slowed, and this heat is use to convert water into steam which in turn used for rotation of turbine thus producing electricity. This nuclear energy supplements the total energy requirement of our country with an aim to achieve energy security from all the sources including renewable, hydro and coal.

In the end, recommendations for way ahead for India to achieve total energy security. CHAPTER II INDIAS ELECTRICAL ENERGY NEED AND PRESENT STATUS Indias Energy Security Challenge[3] 1. Electricity is one of the most important inputs to support the growing economy. Today, there is the requisite buying power to support the rapid growth of the power sector. At the same time, there are severe resources constrains looming large. The non-availability of power in required amounts could, in fact, severely restrict our developmental aspirations. 2. There is a need to look at nuclear energy associated with processes involving the nucleus of an atom in several million folds higher than the energy associated with processes that involve electron that orbit around the nucleus. The later forms the basis of energy through burning of fossil fuels. Nuclear energy released through fission or fusion of atomic nuclei and solar energy that we receive from the sun are the only two viable basic energy sources capable of meeting our long term energy needs. 3. Electricity Present Status in India?[4] India is a power deficit country with a high base and peak load deficit of around 9.8% and 16.6%, respectively. Currently, though coal-based plants contribute around 58 % of the installed capacity, that alone would not be sufficient to secure and fulfill Indias long-term Energy requirements. A broad estimate suggests that if the countrys coal consumption continues to grow at 5% pa, going ahead we might run out of coal reserves over the next 40-50 years, and even if new coal reserves are discovered and extracted, we might still run out of coal in the next 70-80 years. Installed Capacity > 120 GW. Gross Generation is 620 billion kWh. The current per capita power consumption in India is about 612 KWH per year. While the world average is 2596 KWH. Out of total power available in India, thermal power constitutes 64.6%, hydro power 24.7% and nuclear power 2.9%. The present power status of India is shown in fig 1. The details of nuclear power is s hown in fig 2 Indian Energy Scenarios: 2030 4. Nuclear Power[5] will play a significant role in the long-term energy mix of the country with the government planning to raise its contribution from the current level of 2.9% (4,120 MW) to around 10% (64,000-65,000 MW) of the countrys installed capacity by 2030.[6] 5. Details of Nuclear Power Plants in India.[7] Currently, seventeen nuclear power reactors produce 4,120 MW (2.9% of total installed base).

Department of Atomic Energy. This independent department has all matter related to atomic energy under its purview, and is responsible for designing, commissioning, constructing and operating nuclear power plants. 12. National Electricity Policy.[8] The GOI decided and notified the National Electricity Policy in Feb 2005 (Min of Power, 2005). The policy aims at accelerated development of power sector, providing supply of electricity to all areas and protecting interests of consumers. The policy prescribes development of rural electrification distribution backbone to be completed in next five years, Some of the points on which the policy emphasizes on are:- (a) Nuclear power is an established source of energy to meet the base load demand. Share of nuclear power in the overall capacity profile will need to be increased significantly. (b) Creation of adequate generation capacity with a spinning reserve of a least 5% by 2012 with availability of installed capacity at 85%. (c) Full development of hydro potential. (d) Development of National Grid. (e) Exploitation of non-conventional energy such as small hydro, solar, biomass and wind for additional power generation capacity. 13. Outcome of the Deal. The Indian nuclear power industry is expected to undergo a significant expansion in the coming years thanks in part to the passing of the Indo-US nuclear deal. This agreement will allow India to carry out trade of nuclear fuel and technologies with other countries and significantly enhance its power generation capacity. India is expected to generate an additional 25,000 MW of nuclear power by 2020, bringing total estimated nuclear power generation to 45,000 MW. Following a waiver from the Nuclear Suppliers Group in September 2008 which allowed it to commence international nuclear trade, India has signed nuclear deals with several other countries including France, United States, Namibia, Mongolia and Kazakhstan while the framework for similar deals with Canada and United Kingdom are also being prepared. In February 2009, India also signed a $700 million deal with Russia for the supply of 2000 tons nuclear fuel. India now envisages to increase the contribution of nuclear power to overall electricity generation capacity from 4.2% to 9% within 25 years. In 2010, Indias installed nuclear power generation capacity will increase to 6,000 MW. As of 2009, India stands 9th in the world in terms of number of operational nuclear power reactors and is constructing 9 more, including two EPRs being constructed by Frances Areva. Indigenous atomic reactors include TAPS-3, and -4, both of which are 540 MW reactors. Indias $717 million fast breeder reactor project is expected to be operational by 2010. 14. Nuclear Power Growth. India, being a non-signatory of the Nuclear Non-Proliferation Treaty, has been subjected to a defacto nuclear embargo from members of the Nuclear Suppliers Group (NSG) cartel. This has prevented India from obtaining commercial nuclear fuel, nuclear power plant components and services from the international market, thereby forcing India to develop its own fuel, components and services for nuclear power generation. The NSG embargo has had both negative and positive consequences for Indias Nuclear Industry. On one hand, the NSG regime has constrained India from freely importing nuclear fuel at the volume and cost levels it would like to support the countrys goals of expanding its nuclear power generation capacity to at least 20,000 MW by 2020. Also, by precluding India from taking advantage of the economies of scale and safety innovations of the global nuclear industry, the NSG regime has driven up the capital and operating costs and damaged the achievable safe ty potential of Indian nuclear power plants. On the other hand, the NSG embargo has forced the Indian government and bureaucracy to support and actively fund the development of Indian nuclear technologies and industrial capacities in all key areas required to create and maintain a domestic nuclear industry. This has resulted in the creation of a large pool of nuclear scientists, engineers and technicians that have developed new and unique innovations in the areas of Fast Breeder Reactors, Thermal Breeder Reactors, the Thorium fuel cycle, nuclear fuel reprocessing and Tritium extraction production. Ironically, had the NSG sanctions not been in place, it would have been far more cost effective for India to import foreign nuclear power plants and nuclear fuels than to fund the development of Indian nuclear power generation technology, building of Indias own nuclear reactors, and the development of domestic uranium mining, milling and refining capacity. 15. India has already been using imported enriched uranium and are currently under International Atomic Energy Agency (IAEA) safeguards, but it has developed various aspects of the nuclear fuel cycle to support its reactors. Development of select technologies has been strongly affected by limited imports. Use of heavy water reactors has been particularly attractive for the nation because it allows Uranium to be burnt with little to no enrichment capabilities. India has also done a great amount of work in the development of a Thorium centered fuel cycle. While Uranium deposits in the nation are limited, there are much greater reserves of Thorium and it could provide hundreds of times the energy with the same mass of fuel. The fact that Thorium can theoretically be utilized in heavy water reactors has tied the development of the two. A prototype reactor that would burn Uranium-Plutonium fuel while irradiating a Thorium blanket is under construction at the Madras/Kalpakkam Atomic Power Station. CHAPTER III NUCLEAR ENERGY ITS MYTH AND REALITY Nuclear Energy in India[9] 1. Nuclear energy is the fourth-largest source of electricity in India after thermal, hydro and renewable sources of electricity. As of 2008, India has 17 nuclear power plants in operation generating 4,120 MW while 6 other are under construction and are expected to generate an additional 3,160 MW. Since early 1990s, Russia has been a major source of nuclear fuel to India. Due to dwindling domestic uranium reserves, electricity generation from nuclear power in India declined by 12.83% from 2006 to 2008. To appreciate the Indo US nuclear deal better, let us understand the basics of generation of nuclear energy. 2. Nuclear Reactor. The basis of nuclear power is the fission process. This is the process of splitting of a fissionable atoms nucleus, releasing energy in the form of heat, which can be converted through steam turbine and a generator into electricity. The only naturally occurring fissionable material is Uranium and said to be fissile because its nucleus has an affinity to a colliding neutron which it absorbs, splits into two smaller particles and emits two or more neutrons and produces vast amounts of energy. This process is called fission chain reaction. The neutrons produced as result of fission reaction in the reactor have excessive energy levels and they move at a great speed. In a nuclear reactor a chain reaction cannot be sustained with fast moving neutrons. So the fast paced neutrons are slowed down by an element called a moderator. The two substances that are used as a moderator in a Uranium reactor are heavy water and graphite. A majority of the nuclear reactors in the worl d use natural uranium as fuel and light water as moderator and hence they are called the Light Water Reactor. These are essentially boiling water reactor (BWR) or Pressurized water reactor (PWR). In a BWR, the cooling water is allowed to boil inside the reactor at a temp of 290 deg and pressure of 70 atmospheres. The steam is then fed directly to the turbines and re-circulated to the reactor. In a PWR the pressure inside the reactor vessel is kept at 150 atmospheres so as to prevent the cooling water from boiling at temperatures up to 350 deg. This water is fed out of the reactor vessel to a steam generator where it passes through thousands of tubes immersed in water at a much lower pressure. The secondary cooling water boils and drives the turbines. The other type of reactors those use heavy water as moderator is called Pressurised Heavy Water Reactor (PHWR). 3. Nuclear Fuel Cycle. Nuclear fuel needs to be processed optimally for use and thereafter disposed off safely. All these activities form part of the nuclear fuel cycle. Indias share of Natural Uranium reserve of the entire globe is 0.8 %. At the same time that of Thorium is over 32% of the worlds reserve. A Uranium Mill is a chemical plant designed to extract uranium from ore. The final product that goes out of from the mill, commonly referred to as yellow cake, contains more than 60% of uranium. 4. Nuclear Waste Reprocessing. The fuel which went into the reactor is removed after anywhere between 18 months to about 3 years. This spent fuel highly radioactive waste. The Uranium which comprises about 96% of the spent fuel can be recycled as fresh fuel elements. It could be used to fuel breeder reactors or can be used to make a nuclear bomb. 5. Uranium Enrichment. Purification and chemical conversion of uranium concentrate to uranium hexafluoride is needed since yellowcake is not directly usable as nuclear reactor fuel. The uranium hexafluoride is used in a natural uranium fuel reactor. The enriched uranium is now sent to a fuel fabrication plant where it is changed into uranium dioxide powder. The powder is pressed into small pellets, which are then put into metal tubes, forming fuel rods. These fuel rods are put together to form a fuel assembly. Advantages and Disadvantages 6. The advantages of electricity produced from nuclear source are as follows :- (a) Cost- Effective Option. A kilogram of uranium can produces a million times more energy as compared to a kilogram of coal or a kilogram of hydrocarbon. One kg uranium can produce as much electricity as 1500 tons of coal. It will not only diversify Indias power generation portfolio but also reduces pressure on railway transportation of coal for the thermal power plants. (b) Environmentally Sustainable. Non-emission of greenhouse gases that have threatened the global climate. The reduction in annual coal consumption ~ 100 Million Tons. Reduction in annual CO2 Emissions > 170 Million Tons. This will help ease global demand for crude oil and natural gas. 7. The disadvantages of nuclear power plants are as follows :- (a) Initial Cost. Conventional nuclear plants are expensive, being perhaps two to three times the cost of comparable coal or gasification plants, with much of this expenditure required to insure the safety of the public. The production process is relatively simple and involves using nuclear heat to create steam that subsequently drives a turbine generator. However, the high cost of the plants (billions of dollars) can introduce potentially high financial risks to owners and investors alike, as history has demonstrated. While the plants are relatively inefficient (~33%), the price of nuclear fuel, as with coal, is a fraction of the cost of natural gas. Nuclear plants operate at full power for technical reasons and avoid the daily routine large load swings of the electrical grid. Fossil plants are normally used for such purposes. Indias Nuclear Energy Programme 8. Indias nuclear resource endowments are modest in terms of uranium, which is the only naturally available material that contains a fissionable component. On other hand thorium endowments are vast. But unlike uranium it is non fissionable. 9. Three-StageProgramme Indias strategies for large scale development of nuclear energy focused towards utilization of thorium and three stages nuclear power program is as given under : (a) The first stage of Indian Nuclear Power employs the PHWRs fuelled by uranium, to produce plutonium. (b) The second stage, Plutonium put in Fast breeder reactor with uranium, with a blanket of thorium, to convert some of the thorium into uranium. (c) In the third stage, Advanced Heavy Water Reactors (AHWRs) would burn Thorium and U 233 as fuel. This is what we finally want to achieve in the years to come. The AHWR test reactor is in final phase of design. 10. Nuclear Energy for Indias Energy Security.[10][11] The CHAPTER IV Indo US Civilian Nuclear Deal Indo-US Relations 1. Historical Perspective. The nuclear energy history started way back in 1950 when US helped India to develop nuclear energy under the atoms for peace program. In 1968 India refused to sign the Non-Proliferation Treaty (NPT) claiming it was biased. India, Pakistan and Israel never signed NPT and North Korea signed but withdrew later. In 1974 came a turning point when India tested its first nuclear bomb made by the materials from the Canadian reactor. Canada and US stopped selling nuclear fuel to India and US placed severe restrictions on transfer of dual use technologies to India. India was a target of American ideological and geopolitical antagonism. Bilateral relations between the two countries were victims of incompatible obsessions of Indias with Pakistan and Americas with the erstwhile USSR. 2. Post Pokharan II. Indias nuclear blasts of 1998 not only shook the Thar desert, but also rocked the very foundations of the Global Nuclear Order. US administration promptly imposed sanctions and also mobilized other nations in doing so. Indias nuclear policy thus became the single most contentious issue in bilateral relations. The country was treated like pariah, especially by the US and 45 member Nuclear Suppliers Group (NSG) countries and isolated India for more than three decades, refusing nuclear co-operation. Sanctions were heaped on India. Indian nuclear scientists were unwelcome at international seminars in their field. 3. Post 9/11. In 2000, the US has moved to build a strategic partnership with India. The terrorists strike of 11 Sep 01 resulted in convergence of strategic interests of both the sides. India supported American actions whole heartedly and defence cooperation was at new heights. An agreement on Next Steps in Strategic Partnership (NSSP) was signed in Jan 2004 which included areas such as missile defence, cooperation in civilian nuclear, space programme and high technology trade. The foundation and indeed the underpinning of the nuclear agreement was the signing of a ten year New Framework for Defence Relationship (NFDR) in June 2005 as a prelude to the historic agreement of 18 Jul 05, when India and the US agreed to cooperate in the field of civilian nuclear agreement. Landmark Deal 4. On 18 Jul 2005, India and the US sign the landmark Civilian Nuclear Deal in Washington DC and surprise the world. The deal was signed by US President Mr George Bush and Indian Prime Minister Dr Manmohan Singh. The US dismantle the complex architecture that it had set up to isolate India after 1974 nuclear test and deny it access to civilian nuclear technology. 5. Hyde Act. On 18 Dec 2006, the US congress passed the Henry J Hyde United States-India peaceful atomic energy co-operation act 2006 (PAEC Act 2006) popularly called as ‘Hyde Act, amending the atomic energy act that had prohibited American entities from trading with countries that didnt sign the NPT or had done a nuclear test. India fitted into both categories. The US Senate voted emphatically in favor of 86 to 13. In reality, the Hyde Act is an enabling legi

Plant Pigments and Photosynthesis

Plant Pigments and Photosynthesis Analysis 1. The solubility and the intermolecular bonds formed between the solute and the solvent are involved in the separation of pigments as it moves through a filter paper. 2. The Rf values would be different if a different solvent was used because the solvent would have different characteristics which affects the capillary action (because the Rf value is distance pigment migrated (mm) / distance solvent front migrated (mm), the capillary action would have a large impact on the Rf value), attraction of solvent molecules to one another, and each pigment will not be equally soluble to the original solvent. 3. The reaction center of photosynthesis contains chlorophyll a. Other chlorophyll a molecules, chlorophyll b, carotenes and xanthophylls capture light energy and transfer it to the chlorophyll a located in the reaction center. Carotenoids also protect the photosynthesis system from damaging ultraviolet rays. Part B Purpose Condition of Chloroplast vs. Rate of Photosynthesis: The purpose of this lab is to observe and measure the effect of boiled and unboiled chloroplast on the rate of photosynthesis of a chloroplast suspension made from spinach leaves. Presence of Light vs. Rate of Photosynthesis: The purpose of this lab is to observe and measure the effect of the presence of light on the rate of photosynthesis of a chloroplast suspension made from spinach leaves. Variables Condition of Chloroplast vs. Rate of Photosynthesis  · Independent Variable: Condition of chloroplast  · Dependent Variable: Rate of Photosynthesis; this will be measured by determining the percent transmittance of each chloroplast suspension.  · Controlled Variables: Amount of DPIP (mL), Temperature ( °C), and Amount of Phosphate Buffer (mL) Presence of Light vs. Rate of Photosynthesis  · Independent Variable: Presence of Light  · Dependent Variable: Rate of Photosynthesis; his will be measured by determining the percent transmittance of each chloroplast suspension.  · Controlled Variables: Amount of DPIP (mL), Temperature ( °C), and Amount of Phosphate Buffer (mL) Hypothesis If the condition of the chloroplast in the suspension was unboiled, and there was light present, then there will be photosynthesis occurring in the cuvette. Photosynthesis the process by which the chloroplast within the leaf cells of green plants use sunlight to synthesize foods from carbon dioxide and water. In order for photosynthesis to occur, the chloroplast needs to be functioning, and light needs to be present to excite electrons for NADP to bind with. Because unboiled chloroplast and light are both present in cuvette 3, photosynthesis occurred rapidly. But if boiled chloroplast and light were present, photosynthesis would not occur. Boiling the chloroplast would rupture and destroy the chloroplast, therefore ceasing the process of photosynthesis. If unboiled chloroplast was in the cuvette, but light was absent, photosynthesis would not occur. Light is important in the process of photosynthesis. Light striking photosystem II is the cause of the excited electrons that bind to th e NADP, but in this experiment, the compound, DPIP, will be used as a substitute to determine percent transmittance. Therefore, without properly functioning chloroplast and light present, photosynthesis in the cuvette will not occur. Procedure First set up an incubation area that includes a light and a heat sink. Use a 100 mL beaker or flask filled with water to be placed between the light source and the cuvettes. Then, because you need to keep the chloroplast suspension cool, fill a bucket three quarters full with ice. Prepare the cuvettes by wiping all sides clean. Remember to handle them by touching the sides with the ridges. All solutions should be free of bubbles. Place cuvette position with the clear side facing the light source in the colorimeter. Label the caps of the cuvettes with numbers 1, 2, 3, 4, and 5. Then make a foil container and a cap for cuvette 2 and make sure it can be easily removed so you it can be placed into the colorimeter for percent transmittance readings. This will keep the light out of cuvette 2 because it is a control. Remember to replace the foil between readings. Label the provided pipettes â€Å"B† for boiled chloroplast and â€Å"U† for unboiled chloroplast. Obtain the boile d and unboiled chloroplasts. Fill the bulb of each pipette to about one-third its total size. Invert the pipettes and place them in your ice bath. Be sure to keep both chloroplasts on ice at all times. When you are dispensing the chloroplasts into the cuvette, gently shake the pipette to resuspend the chloroplasts. To cuvette 1 add 1 mL of phosphate buffer, 2.5 mL of distilled water, and 3 drops of unboiled chloroplasts; cuvette 2 add 1 mL of phosphate buffer, 1.5 mL of distilled water, 1 mL of DPIP, and 3 drops of unboiled chloroplasts; cuvette 3 add 1 mL of phosphate buffer, 1.5 mL of distilled water, 1 mL of DPIP, and 3 drops of unboiled chloroplasts; cuvette 4 add 1 mL of phosphate buffer, 1.5 mL of distilled water, 1 mL of DPIP, and 3 drops of boiled chloroplasts; cuvette 5 add 1 mL of phosphate buffer, 1.5 mL + 3 drops of distilled water, and 1 mL of DPIP. Link the computer to the colorimeter, and prepare Logger Pro. Add three drops of unboiled chloroplasts to the water and ph osphate buffer as indicated in the table. Cap the cuvette, place it into the colorimeter and use it to calibrate the colorimeter. Finally, add three drops of unboiled chloroplasts to cuvette 2, immediately start your stopwatch, and record the time and transmittance in the data table. Return the cuvette to its foil container and place it behind the heat sink. Add three drops of unboiled chloroplasts to cuvette 3, immediately record the transmittance and time. Add three drops of boiled chloroplast to cuvette 4, and record the time and transmittance. Check and record the transmittance of cuvette 5, which is the control. Record time and transmittance. Remember to check the transmittance of each cuvette at five-minute intervals from when the chloroplasts were added up to 15 minutes. Conclusion Functioning chloroplasts and the availability of light are two important factors for the rate of photosynthesis. Light is needed to excite the electrons from the water molecule. Then the excited electron binds with NADP, or in this case, DPIP. When the DPIP accepts the electron, the compound begins to degrade. A greater concentration of DPIP is easily seen inside a cuvette because of the dark blue dye associated with the DPIP. As DPIP degrades, the color of the chloroplast solution begins to get lighter. A solution without DPIP would be clear. Percent transmittance would be greater if more light passes through the solution in the colorimeter. If a cuvette had functioning chloroplasts and was exposed to light, the DPIP would be breaking down at a faster rate in the controlled time, which would mean there are less DPIP compounds in the cuvette, resulting in a lighter colored suspension; the amount of DPIP is directly related to the shade of the solution. The percent transmittance is de termined from the shade of the suspension; the lighter the solution, the smaller the amount of DPIP remaining. Therefore, the decrease of DPIP in the given time would indicate that photosynthesis is indeed occurring in the cuvette. Our hypothesis is supported by the data because we hypothesized that fully functioning chloroplast with the presence of light would result in the occurrence of photosynthesis. In this experiment, we tested and observed the effect of the condition of chloroplast and the presence of light on the rate of photosynthesis. In cuvette 2, we added unboiled chloroplast and did not allow light to penetrate the cuvette. So we used aluminum foil to block out the light from the light source behind the heat sink. At 0 minutes, the light transmittance was at 17.5%. But 10 minutes later the percent transmittance was at 19.9%. The data indicates that where was a small amount of DPIP reduced. When we removed the cuvettes foil shell to measure transmittance, light was introduced to the suspension. This indicates that the very little photosynthesis that occurred was the result of the light that excited electrons for DPIP to accept during the seconds between the removing and the replacing of the aluminum cuvette castings. In cuvette 3, there was unboiled chloroplast and light introduced to the mixture of distilled water, phosphate buffer, and DPIP. As you can see from the provided data table and graph, at 0 minutes, the transmittance was 18.09%. But 10 minutes later, the percent transmittance rose to 96.26%. Light struck the functioning chloroplast, excited electrons, and caused DPIP to break down as it accepted the electrons. This is evidence of photosynthesis occurring at a very fast rate inside cuvette 3. But 15 minutes later, the transmittance of cuvette 3 was to 96.83%. This shows that the rate of photosynthesis slows down, but this was the cause of the scarce amount of DPIP. The rate of photosynthesis was so fast that it used up almost all of the available DPIP in 10-15 minutes. In cuvette 4, there was boiled chloroplast in the suspension, and light was present. At the initial time, 0 minutes, percent transmittance was at 24.32%. 10 minutes later, the solution had a 28.47% tr ansmittance. There is a slight increase in transmittance, but exposure to light can cause DPIP to break down. If photosynthesis had occurred, it would have occurred at a much faster rate. The data would be similar to cuvette 3s data, but because of the slight increase of transmittance, photosynthesis did not occur. This proves out hypothesis that for photosynthesis to occur, light and functional chloroplast must be present. When the chloroplast was boiled, this destroyed the chloroplast. Therefore, without functioning chloroplast, photosynthesis will not occur. Cuvette 5 was the control; chloroplast was not added to the solution. At 0 minutes cuvette 5 had a transmittance of 25.22%. 10 minutes later cuvette 5s transmittance was 22.60%. This decrease is due to experimental error. Without light, functional chloroplast would be no use. In order for photosynthesis to occur, light must be present to excite the electrons. Because of the absence of light, DPIP will not degrade due to accepting excited electrons, for instance, cuvette 2s data. Without fully functional chloroplast, there will not be any electrons in photosystem II to excite, and the DPIP will not degrade because there arent any excited electrons to bond to, for example, cuvette 4. This data proves that for photosynthesis to occur, fully functional chloroplast and light must be present. Analysis The DPIP will be used to substitute the NADP electron acceptor. When light strikes the chloroplasts, the electrons are boosted to a higher energy level, which will reduce the DPIP, turning it from blue to colorless. The DPIP replaces the NADP molecule. Electrons used to reduce DPIP are obtained when a water molecule is split. The colorimeter in this experiment measures the amount of light received at the sensor across from the light source in the colorimeter. If the chloroplast suspension, which is placed in between the light sensor and the light source, is darker in color, then we can imply that the DPIP in the solution has not yet broken down, which confirms that photosynthesis is not occurring. Darkness inhibits the reduction of DPIP; because the light waves are not exciting the electrons in the chloroplast, the DPIP is not breaking down. Therefore, the DPIP remains in great numbers in the chloroplast suspension. The more DPIP, the darker the solution. Boiling chloroplasts does not affect the reduction of DPIP. When the chloroplast is boiled, it is nonfunctional. Because the chloroplast is nonfunctional, the photosystem II is unable to receive the light and excite the electron. Because the electrons are not excited, the DPIP is not reduced. Chloroplasts that were incubated in the light are able to harness the energy from the light to excite electrons that is then accepted by DPIP. This causes a reduction of DPIP, which makes the originally blue chloroplast suspension to lighten in color. The lighter the solution, the greater the percent transmittance, because more light can pass through the solution in the colorimeter. Chloroplasts that were kept in the dark do not receive light and cannot excite electrons. The DPIP compounds are not broken down, which results in a darker blue suspension. When this is placed into the colorimeter to measure percent transmittance, less light will be able to travel through the suspension due to the dark-blue color of the suspension. Cuvette 1: was used to calibrate the colorimeter. This cuvette did not contain DPIP, which would resemble 100% transmittance because of the lack of dye in the solution. Cuvette 2: contained unboiled chloroplast and was kept in the dark. This was used to confirm that both functional chloroplast and light are needed for photosynthesis to occur because the combination of unboiled chloroplast and the absence of light did not produce a significance increase in percent transmittance. Cuvette 3: contained functional chloroplast and was placed in the light. The significant increase of percent transmittance proves that both functional chloroplast and significant light are necessary for photosynthesis to occur. Cuvette 4: contained boiled chloroplast and was placed in the light. The function of this cuvette was to prove that functional chloroplast and light are needed for photosynthesis to occur, but the small increase in percent transmittance may have been the result due to the light breaking down DPIP. Cuvette 5: did not contain any chloroplast or light. This cuvette was used as a control. It would be used as the â€Å"baseline† when analyzing data because it can reveal any effects that is experienced by the cuvette that did not result from the presence of chloroplast or light.

Music, Radio and Teens Essay -- Hip Hop Rap Essays Music Musical Essay

Music, Radio and Teens The first thing that teenagers will do when they get into their car is to turn on the radio. They flip through the channels hoping to find that latest hit that all the stations are playing. Whether it's the newest pop rock song, or that catchy country tune, everyone wants to hear it. This is an example of how powerful the radio can be in influencing what teens listen to. Here is a closer look at the specific genres and how these styles are affecting today's teens through the radio. Hip Hop Hip-Hop is one of fastest growing music genres in the United States as its trend has made hip-hop explode everywhere. Hip-Hop comes from the streets using street slang incorporated in the music. Hip-Hop music is rebellious and frightens parents due to the explicit lyrics that it uses. As any type of new generation beat that is rebellious is going to scare a parent. Parents are frightened that if their kids listen to this music it will promote violence, sex, and drugs. Parents need to know that the vibe that teens get from Hip-Hop is just like the vibe our parents got from rock and roll. As teens are influenced by the Hip-Hop culture by the way teens dress themselves wearing brand names like Tommy Hilfiger, Nautica, or Polo to represent the hip-hop culture; getting away from the preppy clothes like for example Abercrombie and Fitch. Hip-Hop music has no color barrier so anybody can listen to the music. Hip-Hop has even reached magazine shelves attracting more teens to read a bout hip-hop magazines like The Source, Jive, and XXL are devoted to just Hip-Hop music. Hip-Hop has influenced a lot of teens and will continue to grow as the new generation of music the so-called ?feels good music? that teens lo... ...the car. HIP-HOP.

A Mother Critical Analysis Essay -- essays research papers fc

A Mother’ ‘A Mother’ is one of the short stories that is part of James Joyce’s literary masterpiece Dubliners. The themes that run through this short story, and indeed the book itself, are: Simony, Gnomon and Paralysis. ‘A Mother’ is written in third person omniscient narration and focuses mainly on the point of view of Mrs Kearney. Who is, as I will try to justify further on, a serial simoniac and a victim of social convention. The first example of Mrs Kearney’s simony is her marriage to Mr Kearney, a bootmaker, who is far older than her. She married, not for love, but in order to keep her status in society respectable: â€Å"her friends began to loosen their tongues about her she silenced them by marrying† (pg 153) Another example of Mrs Kearney’s simony is when she manipulates Mr Holohan into signing into a contract with her daughter. She plies him with alcohol and lends a friendly hand in drawing up the terms of the contract. I believe that when Mrs Kearney is being said to have â€Å"slipped the doubtful items in between the old favourites† (pg 155) as she and Mr Holohan are placing the performers in order for the concert, that Joyce is also hinting that this is what Mrs Kearney had done with the contract. She has confused Holohan with drink so that she can secure a high price for her daughter’s part in the concert. This story is full of the theme of the gnomon also. In the beginning we learn that Mr and Mrs Kearney have two daughters, yet we never learn the younger daughter’...

APN Interviews: Caring, Competency, and Compassion Essay

The healthcare system is ever changing and the need for advanced practice nurses will be in demand. I had an opportunity to interview two advanced practice nurses. Jolene and I met at her home in St. Charles, IL Jolene graduated from the University of Colorado at Denver in 2005 with a master’s degree in nursing and was granted the title: Family Nurse Practitioner (FNP). She got married and accepted a position as a Primary Care Provider at VNA Health Care in Aurora, Ill. VNA Health Care is a federally qualified health center serving the uninsured. In the year 2000, Jolene’s mother was diagnosed with breast cancer. As a loving daughter, she supported her mother through a cancer free journey today. From this experience, Jolene came in contact with all kinds of nurses and because she loves people of all ages, she became inspired to be a family nurse practitioner. I met Linda at her office at Women First in Aurora, Il. In 1974, Linda graduated from Northern  Illinois Unive rsity with her BSN in nursing. Linda worked many years as a nurse in woman health, especially in the OB Department at Provena Mercy Center in Aurora, Il. In 1980, after her daughter entered grade school, Linda decided she wanted pursue a master’s degree in nursing. In 1983 she graduated from the University of Illinois with a master’s degree in nursing and earned the title: Certified Nurse Midwife (CNM). Linda has worked in many in woman’s health practices with physicians and in 1997 established Woman First, Inc., which specializes in midwifery care and woman’s health from puberty to menopause. Linda entered nursing because with her mother being an RN she was exposed to nursing growing up. When she was working as a labor and delivery nurse at Provena Mercy Center and personally experienced midwifery care with her daughter’s birth, this inspired Linda to become a certified nurse midwife Jolene and Linda’s typical day in the clinic are similar because they see patients. In family practice, Jolene will see 40 patients a day, ranging from school physicals, to immunizations, to managing uncontrolled diabetic patients. At Woman First, their practice is different because of OB care. Along with providing routine health care to women, CNMs take an on-call schedule at the hospital to give labor support and help mothers deliver their babies. They also make hospital rounds with the practice’s inpatients and participate in committee meetings for woman health. Caring and Compassion ring through the practices of these two APNs. At the VNA Health Center, Jolene is happ y with her practice and the support she receives from the VNA family. She feels if she can educate diabetic patients, manage their care and listen to them, evidence from her practice shows the patients are more compliant. Jolene practices with in her role as a FNP meaning she takes a holistic approach: (mind, body, and spirit). Over 20 years Linda has pioneered midwifery care in the Aurora area. She was one of the first CNMs to deliver babies in the hospital setting using labor support and delivery of her patients. The hospital has supported midwifery are for more than 20 years. Linda loves being a CNM. She feels very fortunate to practice and give comprehensive healthcare to women and to empower them to make fully informed choices in their health care. Evidence has shown a decrease of cesarean sections and increases of healthy birth outcomes at Woman First. The APNs sit for certification exam based on knowledge and the need to practice safely in NP specialty area.  Jolene obtained certification from the American Nurses Credentialing Service (ANCS), a national certifying body. She received the title of Family Nurse Practitioner (FNP). Linda became certified through the American College of Nurse Midwives Certification Council (ACNMCC), and granted the title of Certified Nurse Midwife (CNM). Recertification for the FNP is every 5 years and for the CNM is every 8 years. Jolene and Linda have full prescriptive authority and may prescribe schedule II-V but require some degree of physician involvement. The medication schedule II-V involves controlled substances and non- controlled substances. Each practitioner has a DEA and NPI number. The DEA registration is required to prescribe controlled substances and NPI number is required on all non controlled substance prescriptions. Linda explained having full prescriptive authority gives her the freedom to practice midwifery care. Pregnant patients have the option to choose natural childbirth, a birth with some medication, or even epidural anesthesia. In order for APN’s to practice in certain situations in Illinois APNs need collaborative agreements. Jolene commented that she has a supervisory collaborative agreement with a family practice physician at the VNA health center.It is a legal document between the physician and FNP stating the relationship and similar unique practice skills of each individual. Linda has had a collaborative agreement with the same ob./gyn physician for the past 20 years. They have built a close professional and personal relationship to give woman excellent health care. The purpose of this agreem ent is having specific guides for CNM care, protocols and standing orders including prescriptive authority. Both women described their credentialing and privilege process within the VNA health center and at Proverna Mercy Center. Jolene went through an interview process with the human resource department and the medical director of the health center. She supplied them with her application, licensure, education, and documentation of experience and clinical competency. The process was different for Linda because clinical privileges at Provena Mercy Center involve a detailed processing. Credentialing is the first process; same as Jolene the credential and competency documents are supplied  through the HR department. The difference in Linda’s process, she received a recommendation from her sponsored physician and extensively interview with the medical review board. The result of the interview and information supplied is used to make a decision to grant privileges Both Jolene and Linda had a 90-day period of time focused on professional practice under their collaborative physicians. With ever-changing health care in APN practices active membership and participation is needed in professional’s organizations. Jolene expressed she is not a member of the American College of Nurse Practitioners (ACNP) because of personal financial problems. Linda is a member of the American College of Nurse-Midwives (ACNM). The example Linda gave was the ACNM is moving toward integrating certified midwives (CMs) with certified nurse midwives (CNMs). She is very interest in the legislation on this issue. Along that discussion I asked about furthering ones education to Doctor of Nursing Practice (DNP). Jolene commented in the future she would like to pursue her DNP along with her becoming a nurse midwife. The DNP is necessary because the APN scope of practice will widen and more education is needed. Linda received her DNP in 2012 at the University of Illinois. Linda took the clinician expert track in the DNP program because, later in her career, she may want to teach in the clin ical setting. Jolene and Linda are both passionate about their practices—and proud of their contributions to patient recovery. Jolene feels she has helped the underserved and enjoys the variety of disease management. She had a Hispanic man with uncontrolled diabetes. She expressed that patients with chronic diseases tend to have a fatalistic attitude. Jolene, through persistence, convinced him to seek nutritional consults and diabetic education, which caused the man to commit to be compliant and have healthy lifestyle. With Jolene’s help, the man realized he was going to die if he did not take care of himself. Linda contribution to midwifery and woman care is many years of delivering babies, not all deliveries are happy. Some babies are stillborn or babies are born premature, and some with undiagnosed congenital anomalies. Part of  Linda’s spiritual belief is that all babies are gifts from God and all life is precious. An example she related to me was about a Hispanic patient screaming in the labor room. The woman already received some medication for pain. The nurses were getting frustrated at this patient because of the constant yelling. This patient was not a typical midwife patient. Linda was on call when this woman came into the hospital through the emergency room with no prenatal care. Linda came to see the woman and sat down at the bedside and held her hand gently and stroked it her hand. The woman never cried out, Linda did labor support and delivered her baby. After the baby was born, the woman told Linda in broken English that when she touched her the fear lifted from her . It was a pleasure to interview these 2 caring professional women from different APN career paths. Learning about their inspiration entering nursing, sharing day to day details, and the emotion expressed in their compassion for each area of practice. Gaining knowledge of the educational and credentialing process to insure competency in practice and patient safety. Lastly, hearing the personal accounts of their contributions and rewards for giving exceptional patient care.

Video Game Ethical Issues

Kuan-Yu Lin Brenda Varda HMN-101-01 10/28/2012 Ethical Issue Essay: Final Draft Video games have always been an important part of the entertainment industry since its appearance in 1970’s. They have been played worldwide and effect many people. While the children are already playing the games, the number of women gamers, as well as the age level of gamers in general is increasing.As technology advances, video games with more diversity and real-life experience are slowly creeping into parts of our life and gaining its momentum in the society. Due to its quick development, many ethical issues associated with video games have been brought to our attention. Therefore, we should understand how video games are ethically influencing people within its realm. The four major ethical issues which will be discussed are issues of violence, education, stereotyping and addiction. Video games are enjoying fast-growing popularity, becoming a major component of young people's social lives and leisure activities.First of all, a major concern which has been discussed continuously regarding video games is violence. Violence in video games is considered as the visual presentation of characters fighting, gun shooting, physical injury or death to characters. Recently, more and more video games involving violent behavior are taking over the game selection on the shelves. Comparing to games made in the 70’s, 80’s, recent games feature tougher, more aggressive heroines and more games are made specifically for adults.Research consistently declares that most top-selling video games involve violence. In order to prevent the potential harm to children, youth and society of this negative influence, lots of research has focused on the consequence of violent video games. Video game research indicates that playing violent video games increases aggression, hostility, and aggressive thoughts. (Anderson, Buckley, & Gentile, 2007; Anderson & Bushman, 2001; Anderson, Carnagey, F lanagan, Benjamin, Eubanks & Valentine, 2004;Anderson & Dill, 2000).In their research, they conclude that engaging games which have content related to violence may possibly increase a person’s aggressive thoughts, feelings, and behavior in real life. Some other studies focusing on college student playing video games also point out that students playing violent games are also engaging in more aggressive behavior. It has been claimed by many critics of the media industry that the incident at Columbine High School in Littleton, Colorado on April 20, 1999 was caused by the influence of violent video games.It was shown on BBC news that both students shooters, Eric Harris and Dylan Klebold, had played and enjoy violent video games. â€Å"Relatives of people killed in the Columbine massacre are seeking damages from computer game makers, claiming their products helped bring about the killings. † Although video games can help players relieving stress, they can also affect gamer s in a harmful way. It is both the players’ and the game makers’ responsibility to be aware of the negative effects of video gaming. Games with harmful content might be leading negative effects; they still have values considered being beneficial in certain aspect.Games are popular in the community of youth and have many qualities that make them wonderful teaching tools. Through the educational perspective, both adults and children learn many things by playing video games. Games with positive content show positive effects. For example, playing a dancing video game can help children lose weight (Konami’s Dance Dance Revolution, 2007; O’Hannon, 2007; Epstein, Beecher, Graf & Roemmich, 2007). As mentioned before, videogames could be an excellent tool for learning. In particular, players are learning in an active way with practice and feedback.Because they are fun, children are highly motivated with video gaming, when people are motivated, they usually perform better, thus lead in to a better result. Also, games usually have clear objectives with adaptable difficulty levels. Games with increasing difficulty across levels allow player to apply past learning. Lastly, games allow children to apply to what they learn in different problems and contexts. Some believe that video games help improve life skill such as logic and problem solving. They also can improve hand-eye coordination and leadership skills, which can be useful for military training purposes.Having realized the efficiency and the joyful quality of learning experience in gaming, educators are able to take advantage of the positive learning characteristics of games by using the well-designed software in order to teach children more effectively. While the issues associated with violence in video games have caused huge concern among children, gender, and racial stereotypes in video games are also causing problems which require more attention. There is an unbalanced proportion betwe en male and female game players and developers. According to a recent study the average gamer age was in the mid to late 20's with 60% men playing and 40% women. †2 The whole gaming industry is overwhelmed by the male population. Most of the games on the market are targeted to only male players. Dietz’s, one of the earliest studies to examine stereotypical portrayals in video games, analyzed the depiction of women in a sample of 33 most popular Nintendo and Sega Genesis video games. The study categorized the female characters in those games into four possible stereotypes based on their appearances and behaviors. Females as sex objects or prizes, females as victims, females in feminine roles, and females as heroes or action characters. Not surprisingly, Dietz (1998) found that 41% of the games were devoid of female characters. Only 15% (5 out of 33) portrayed women as heroes or action characters, while 21% (7 out of 33) portrayed women as victims or as so called ‘d amsel in distress’. At the same time, in 28% of these games, women were portrayed as sex objects based upon physical appearance or sexually-oriented actions. Following the discussion of female character as indicator of sexuality, most of the female characters in video games have clothing that exposed more skin than the male characters. The research also found out that the female characters appearing in gaming most likely wear low-cut clothing. About half of the female characters have bare arms and legs with big busted figure. * In essence, these female characters in video games were portrayed in a stereotypical way in which they were exaggerated by sexy attire. That leads to the exclusion of female players in video game industry.Although the number of game designed for female gamers is increasing slowly, it is crucial for both consumers and game makers to make the video games more engaging for both sexes either by changing the content of the game or by expanding the choice of games. They should be designed in a way that they are attractive for both male and female players. Finally, the last ethical issue I want to talk about is the addiction of engaging video games. Some people spent immense amount of time playing video games and caused them to lose valuable time participating in activities which are more beneficial for them.However, video games could be considered as one of social activities because friends, siblings, and other relatives can play with it.
