PH Lab Report testing household liquids Essay Example

PH Lab Report testing household liquids Paper Introduction: Substances, even household substances, can be acidic, basic, or neutral. Acids and bases are called aqueous solutions, or mixtures of certain substances dissolved in water. The amount of acidity or basicity can be measured by using the pH scale. The scale runs from 1-14. The scale has to do with the amount of hydrogen ions [resent in a substance. Hypothesis: Our hypothesis for this experiment consists of twelve different substances. The tomato juice will be acidic; the distilled water will be neutral; the Windex will be basic; the vinegar will be basic; the soda will be basic; the milk will be neutral; the buttermilk will be neutral; the baking soda solutions will be acidic; the green cleaner will be basic; the household cleaner will be acidic; the Lemon Juice will be acidic. Materials: For this lab we need pH paper, a spot plate, water (distilled, if available), and substances with varying pH. Safety: In this lab we must were goggles and aprons to avoid skin contact with all chemicals that are going to be used in this experiment.

Procedure: First we get a spot plate and put three to four drops of each liquid substance in each of the wells. The liquid must correspond with the label on the spot plate to avoid contamination. Then we test each substance using the pH paper. The color of the part of the paper that was dipped in the substances was then matched with the indicator colors. After we test each substance, we recorded the data in a data table. Data Table: Substance pH Value Acid, Base or Neutral. Tomato Juice 4 Acid Distilled Water 6 Acid Windex 9 Base Vinegar 2 Acid Soda 4 Acid Milk 7 Neutral Buttermilk 5 Acid Baking Soda Solution 9 Base Green Cleaner 7 Neutral Household Cleaner 10 Base Lemon Juice 3 Acid Tap Water 6 Acid Analysis: 1. ) The pH scale is a measure of the concentration of which ion? * The pH scale is a measure of the concentration of the Hydroxide ion. 2. ) Briefly describe the different properties of acids and bases. * Acids have the lowest pH values or less than 7 on the pH scale. They have the highest concentration of hydrogen ions. The high concentration of these ions gives acids their properties like sour taste. Acids damage living tissue by causing burns upon contact. Bases, however, have the highest values or greater than 7 on the pH scale. They have the lowest concentration of hydrogen ions. Bases have higher levels of hydroxide ion, which gives bases their identifying properties, such as bitter taste and slippery feel. Bases damage living tissue by dissolving it upon contact. 3. ) Give one possible explanation why the pH value for the tap water being different from the pH value for distilled water.

Social Justice Example

Social Justice Example Social Justice – Coursework Example Social Justice Living in social environment has always been considered to be one of the most important prerequisites for the development of the inner potential of a human being. However, there are also instances when one group is able to exercise its influence over another one and dominate in all the areas of social life. A good example is colonization. This paper will analyze the notion of social justice with regard to indigenous people and those who conquered them. Speaking of the former, one might suggest that justice may be manifested in the form of granting them a considerable amount of freedom in various affairs. For example, it would be advantageous if â€Å"indigenous people, as a specific form of exercising their right to self determination, have the right to autonomy or self government† (Churchill, 2003, 424). This way they will be able to preserve their traditional ways of life. As for those who dominate the social life on their territories, one should note that the se conquerors should exercise their powers within a defined framework, so that their rule would not be despotic. Indeed, in this case social justice will come in the form of laws that both parties will strictly comply with. So, the situation of conquering land of indigenous people surely distorts the social justice, but it may be restored in the following way: for aboriginals – in form of granting self government; for conquers – in form of setting just laws that they would comply to so that their rule will be fair and not oppressing.ReferencesChurchill, W. (2003). Perversions of justice: indigenous peoples and Anglo-American law. San Francisco: City Lights Books.

Understanding PTSD Flashbacks

Understanding PTSD Flashbacks A flashback is an intrusive, unintentional, vivid memory of a traumatic event. Flashbacks are one symptom of post-traumatic stress disorder (PTSD). Defining PTSD Post-traumatic stress disorder (PTSD) occurs in the aftermath of a traumatic event, including military conflict,  assault, interpersonal violence, a car accident, or a natural disaster.  PTSD can also occur among first responders,  as well as  people whose loved one experienced a traumatic event. To be diagnosed with PTSD, an individual must experience symptoms in the following four categories  for at least a month after the trauma: Re-experiencing the event. People suffering from  PTSD often re-experience the event in unwanted, unintentional ways, including flashbacks and nightmares.  Avoidance of the event. Someone who is experiencing PTSD will often  try to avoid reminders of the event.Negative thoughts or emotions. The person may experience negative emotions (or a lack of positive emotions), feel self-blame, or lose interest in activities they previously enjoyed.Hypervigilance.  PTSD patients typically feel as thought they are constantly on â€Å"high alert.† They may have trouble sleeping, be irritable, or become easily startled, for example. While many people may develop some of these symptoms immediately after a traumatic event, not everyone who experiences a trauma develops PTSD. What a PTSD Flashback Feels Like Flashbacks can  be incredibly  vivid  and involve  re-experiencing the sights, sounds, and smells that were present during the traumatic event. Some people become flooded with the emotions that they felt at the time of the trauma.  Flashbacks can be so overwhelming and immersive that the person experiencing the flashback may temporarily feel that they have physically returned to the moment of the traumatic event. In some cases, a person experiencing a flashback may behave as though they were back in the traumatic event. Flashbacks can occur as a result of a  trigger- that is, when they notice something in the environment that reminds them of  the traumatic event. However, people can also experience a flashback without being aware of a particular trigger that caused it. Flashbacks vs. Memories Flashbacks occur when individuals involuntarily re-experience a memory of a  traumatic event. Importantly, the psychological definition of a flashback  differs from the common colloquial use of the term. A flashback is  not  simply a â€Å"bad memory. Rather, it is an experience in which an individual actually feels as if they  are re-living parts of the traumatic event. Flashbacks in PTSD are different from intentional memories because they occur without the person trying to do anything to bring back the memory. In fact, psychologist Matthew Whalley and his colleagues have found that patterns of brain activation are different when people are exposed to words that they associate with flashbacks, compared to words that they associate with non-flashback memories. Studies on PTSD Flashbacks   Psychologists have investigated whether it is possible to prevent the development of flashbacks after a traumatic event. Researcher Emily Holmes and her colleagues have suggested that, since flashbacks are often powerful visual images, it may be possible to reduce the severity by distracting the visual system. To test this idea out, Holmes and her colleagues conducted an experiment in which participants watched a potentially traumatizing video.  Afterwards, some participants played Tetris, and others did not. The researchers found that participants who played Tetris only had about half as many flashbacks as the participants who didn’t. In other words, it appears that a neutral activity such as Tetris kept the visual systems in the participants brains occupied, making flashback images less likely to occur. In another paper  by Dr. Holmes’  team, researchers asked emergency room patients who had experienced a traumatic event to participate in a similar study. Some participants played Tetris while others did not, and the researchers found that participants who played Tetris had fewer intrusive memories of their traumatic event over the next week. More broadly, researchers have found that psychotherapy and medication can reduce the severity of PTSD symptoms, including flashbacks. One type of therapy,  Prolonged Exposure,  involves discussing the traumatic event in a safe, therapeutic setting. Another therapeutic technique,  Cognitive Processing Therapy, involves working with a therapist to change ones beliefs about the traumatic event. Researchers have found that both types of therapy are able to lessen the severity of PTSD symptoms. PTSD Flashbacks Key Takeaways Post-traumatic stress disorder is a mental health condition that can occur in the aftermath of a traumatic event.Flashbacks are a PTSD symptom that involve re-experiencing memories of the traumatic event.PTSD flashbacks can be extremely  vivid and may make  individuals feel as though they are re-living the traumatic event.  Several treatments are currently available for PTSD, and new research is investigating whether PTSD flashbacks can be prevented.

Organizational Management Essay Example | Topics and Well Written Essays - 1750 words

Organizational Management - Essay Example Similarly they identify a set of category constructs in the transactional leadership also. For instance concentration on the task at hand, short term goals and tactics, confusion concerning causes and symptoms, too much involvement in power relations, politics and statistics, fulfillment of expectations based on readily available systems, reliance on human interrelations and the persistent support for organizational structures, systems and relations. Warren Bennis (1995) holds the view that less hierarchical more democratic institutions with the ability to adapt to the unfolding environment are the best. A competency-based contingency framework or model like this requires a series of sub-level functions or competencies to be outlined as of consequence though such heterogeneous elements which lie outside the functional domain of the manager's/leader's tasks could be avoided with convenience. For example the manager's/leader's common competencies are always inclusively treated in the theoretical framework for the purpose of reference. This is illustrated by the following diagram. The above diagram (Fig. ... ged framework identifies and addresses the management/leadership competencies and issues that correlate with each other to produce an integral system of reference and analysis (Covey, 2004). For instance the vision & mission of the organization are identified with the long term corporate and business goals, irrespective of the size of the business. Such goals or objectives are essentially strategic in nature because they necessitate a degree of dependence on the organizational culture and leadership to bring about the appropriate environmental characteristics to achieve those long term objectives. Theoretical outline of the competency frameworkDavid Kolb's Experiential Learning teaches the manager to take experience as the source of learning (Kolb, 1983). On the other hand the Myers-Briggs Type Indicator (MBTI) is based on an evaluation of psychometrics that is designed to assess the different psychological behaviors concerning perceptions and decision making preferences of individuals (Myers, McCaulley, Quenk and Hammer, 1998). The manager/leader is a functionary whose primary function/competency to determine the organizational goals is set out in the mission statement and the annual reports to its stakeholders. Thus organizational goals will have to be achieved by utilizing and organizing the available resources and combining them with people or employees in a manner to maximize both output and minimize costs. Towards this end the manager seeks to combine supplies and provisions and then integrate suppliers and creditors into the whole process of management. Next, he needs t o adopt methods in order to build integrated networks or process for easy control and execution of strategy (Williams, 2002). Leadership theories and teamwork models

Reading Report - Essay Example Donovan was not expected to be omitted due to his being a three- time veteran of world cup and the best known American player. Dempsey was however picked due to his absolute advantage over his other fellow players including Donovan. In economics, absolute advantage therefore occurs when an individual, a group or company or a country is more efficient and effective in producing the same good or service than any other individual, company or country. In this case therefore, Clint Dempsey has an absolute advantage over his other players. For instance, he has managed to score eight goals in nine games meaning he scored almost in every game. This is a trait that only a few would achieve. He also has that innate ability of finding a goal in every game he is involved in. The coach of Los Angeles Galaxy Bruce Arena says that he has that driving force with which he does things for himself you can’t keep on telling him during the entire game. He is also very well motivated and uses that as his secret to play well. Another concept in economics is the opportunity cost. This refers to the value of the best forgone alternative. In this case both Dempsey and Donovan are alternatives but the coach has decided to prefer Donovan to Dempsey, thus risking a certain value. The coach has given up the chance to use Donovan and sacrificed the wins they would have had. It meant that Donovan and the value of Donovan was forgone, therefore being the opportunity cost. Opportunity cost is therefore a scenario experienced by most of us in our daily lives (online.wsj.com). Comparative advantage is the ability of an individual or country to produce services or goods at a lower opportunity cost than any other individual or country. Dempsey and Donovan can both play well though Dempsey seems to have an absolute advantage over Donovan. In this case, we don’t look at the absolute advantages but the opportunity costs. The Dempsey can play a

Reducing Gases Emitted from Car Engines Essay Example for Free

Reducing Gases Emitted from Car Engines Essay The automobile industry has become one of the leading pollutants in most urban centers today. The emission of various gases from million of vehicles in roads has contributed to major global problem. Personal cars have emerged as the most notorious ones for this problem especially when they are moving at slow speeds or idling in traffic jams. This is the time when this man made gadgets produces the maximum emissions to the atmosphere with every body around that traffic absorbing the poison. Gasoline and diesel fuels combustion produces a mixture of hydrocarbons mainly carbon atoms, hydrogen as well as oxygen. The hydrocarbons are emitted as fragments of molecules of fuels which are burned partially. They do reactions with nitrogen oxides and in sunlight’s presence to create ground level ozone which becomes a main part of smog. This Ozone is harmful to human health as well as being toxic and sometimes causes cancer. Nitrogen Oxides (NOX) is produced in conditions of high pressure and temperature in the engine. Some nitrogen and oxygen atoms form nitrogen oxides after the reaction. NOX also contribute to creation of ozone as well as acidic rains which are harmful to the environment. NO2 which is much more potential than carbon dioxide as a green house gas is produced in the engine by catalytic conversion of heavy nitrogen gases in car exhausts systems. It contributes up about 7. 2 percent of gases responsible for global warming. Carbon monoxide, a colorless, odorless and poisonous gas is emitted from car engines after incomplete combustion of hydrocarbon-based fuels. It comprises of one atom of carbon and one oxygen atom interlinked together. Jeff Cohen asserts that, these results from having too low air-to fuel ratios in the car engine during the starting process of the car or when the car is not tuned on in the proper way. 1 This also takes place in higher altitudes in which case the amount of oxygen available for burning the fuel is greatly lowered. Transportation sources especially personal cars contributes to about two thirds of carbon monoxide. Carbon dioxide has been perceived as complete combustion product but of late it has been seen as a pollutant since it is a green house gas which traps the heat from the earth resulting to global warming. Of late, Bio-diesel has come up as one of the main renewable fuels and a provider of good opportunity for getting fossil fuel alternatives that assist in reducing emission of these green gases. It is capable of creating good blends in different ratios with diesel either fresh or the used up oil. This implies that Bio-diesel when used either completely or partially with diesel fuel in deferent vehicle engines brings about some economical, environmental as well as social merits. On the other hand, while Bio-diesel contributes to these changes, it also has some challenges on the uncontrolled substances which comprises of carbonyl compounds that are released in the process of emitting the combusted bio-diesels or bio-diesel and diesel blends. Since the fuels are quite different from the normal diesel fuels, they can change the injection as well as ignition processes. Due to this, the emission of green house gases such as CO, CO2, and NOX are greatly affected. This research aims at evaluating the effects of bio-diesel on combustion of diesel fuels as well as their emissions and control in order to obtain a picture of the opportunities and challenges provided by the bio-diesel fuels. 1. Jeff, C. Does Idling Your Car Hurt Gas mileage? Solve Your Problem. com, 2007, retrieved 28 May 2009, http://www. solveyourproblem. com/save-money-on-gas/idling-car-gas-mileage. shtml. Problem statement Most the current car engines are designed to use diesel fuel which is notorious for emitting green house gases. Other engines which employ diesel and bio-diesel mixture have not indicated the most appropriate ratio of mixing the fuels and the optimum speed and rack to emit the least amount of these gases to the atmosphere. The research therefore seeks to obtain the best ration of mixing diesel with bio-diesel or waste oil and the best rack to emit the least amount of gases to the atmosphere. Theses Statement Obtaining the most appropriate ratio of mixing fuels for car engines would assist in reducing the amount of green house emitted from these cars. This would help to aviate the global challenges imposed by the foresaid problem. Objectives Main Objective The main aim of the research is to reduce the amount of green house gases emitted from car diesel engines. Specific objectives These include obtaining the best ratio of mixing several fuels; either diesel with bio-diesel, diesel with waste oil or bio-diesel with waste oil or the best engine speed and rack for this. Scope of the research The research would investigate the most appropriate ratio of mixing different fuels but it has some limitations of financial resources and time. Literature Review There is much concern all over the globe to reduce the emission of green house gases by 10% in the near future. Much emphasis has been on emissions of these gases from transportation fuels. In 2005, the Indian Institute of Technology (IIT) New Delhi came up with a passenger car engine that operated on bio-diesel fuel. This was developed from modifications of the traditional Indica diesel engine that was made some few years ago. The engine used 10 per cent of bio-diesel fuel mixed with diesel to operate the engine. This development, however experiences some significant challenges in that it would take a lot of duration for any manufacture to come up with fully developed bio-diesel engine cars. In March 2009, United Environment and Energy LLC chemists came up with fixed-bed reactor design that was considered energy-efficient and high through in put continuous flow. It was perceived as cost-effective for production of algae oil bio-diesel. This was termed as the first economical approach in production of bio-diesel from algae oil. Although, the design has been able to reduce cost by 40% it did not reduce the emission of green house gases to an effective percentage. Tsinghua University researchers in China in May 2009 tried to use sugarcane juice as a good feedstock indented for production of bio-diesel if utilized to give support to alga Chlorella protothecoides through the process of heterotrophic fermentation. This produced oil content of about 53. 0% by weight of dry cell. In May 2009, Iowa State University Researchers presented a proposal on dissolution of waste polystyrene (PS) in bio-diesel. This aimed at making the bio-diesel for consumption in motor vehicles more so in diesel engines as an approach to recover energy from the waste plastic. The researchers pointed out that the use of polystyrene-bio-diesel blends would lead to increase in engine power thus reduced emissions of green house gases. This still intents increase polystyrene concentrations with 5% as per the study. To help reduce the emissions of green house gases, Tom Harkin and some US senators, in June 2009 proposed to the Environmental Protection Agency (EPA) to halt inclusion of in direct land use change effects as contributor to life-cycle greenhouse gas emissions in rule making indented for carrying out updated Renewable Fuels Standard that demands all bio-fuels to meet some defined life-cycle green house gas emission reduction targets prior to qualification. This research intents to come up with a more convenient approach of reducing the gases emitted from motor car diesel engines by obtaining the most optimum ratio of mixing bio-diesel, waste oil and diesel in car engine at the optimum engine speed. Research Methodology The research is conducted by experimenting the amount of green gases released from a diesel engine when diesel, bio-diesel, and waste oil are used at different to obtain different engine torques while the engine is increases from initial speed of 1500 rpm to 3200 rpm. The three fuels are used either purely or mixed with each other at different ratios while the rack is either maintained at 50% or at 100%. The amount of gases emitted for each condition is recorded in a table. The calves for the different gases emitted obtained at different speeds and racks are then plotted in several graphs. This is used to obtain the best fuel mixture and optimum speed and rack which release the least amount of gases to the atmosphere.

Differences Between Male and Female Orientated Magazine Articles Essay

Investigating the Difference Between Male and Female Orientated Magazine Articles For my investigation I decided to take stories sent in by readers to the magazines FHM and Cosmopolitan. FHM is aimed at men aged around 16 to 30, while Cosmopolitan is aimed at women of the same age. I thought it would be interesting to look at the differences between the two formats because I read FHM quite a lot, and some female friends of mine read Cosmopolitan, and I have often wondered what and how many differences and indeed similarities there are between the two magazines. I was also interested in the different ways similar topics were portrayed for the two different sexes. It helps me understand some of the language and gender issues I dealt with last year in English Language, and that is why I chose a stories page, it tells me more about the people who actually read the magazines than the people who write them. The stories I hoped would reflect the people who wrote them, and therefore the people who bought and read the magazines. It is also interesting for me because I want to become a magazine journalist when I leave university. Doing this investigation allows me to take a more in-depth look at what kind of people enjoy these kinds of magazines, and also it gives me a chance to look at the way these types of articles are presented in magazines, looking at things such as layout. I aim to find differences between the subject matter of the letters, the lexis used by the writers, the differences in grammar, the layout of the letters pages in the magazines and the general tenor of the stories. I also aim to reach a conclusion as to what... ... and "freezing my arse off". These slangy informal descriptions are very suitable for the FHM stories but hardly sensible for the Cosmopolitan story. Overall the articles conform closely with my hypothesis. The variances in the tenor were often and obvious. The male stories also conformed to my hypothesis in that they were competing as an incentive to win a prize, whereas the woman was not. The subject matters also matched my hypothesis. The male stories use mostly a different style of writing to the female articles, and indeed these contribute to them having very different effects on the reader. I think that my investigation has been a success. I have proved many of my hypotheses and my aim has been met. There is a large difference in male and female orientated magazine articles, in both style and substance.

Odysseus’ Obstacles

Epic heroes must overcome obstacles in order to prove themselves true heroes. In The Odyssey by Homer many of the obstacles Odysseus encounters are female, monsters, and seducers. Odysseus overcomes many female obstacles such as Scylla, Circe, Sirens, and Calypso. Ancient Greeks felt women were dangerous. Things would be different if Odysseus encountered more male obstacles because he would have just fought them and won. Odysseus has many experiences with female characters such as Scylla, Circe, Sirens, and Calypso. In order to overcome these obstacles Odysseus had to go threw many difficulties. He ended up having affairs with Calypso and Circe. To overcome these obstacles he left them for Penelope. When Odysseus was stranded on Circe’s island he tried to escape waiting for boats to save him. He came in contact with many other female characters also after he escaped. The ancient Greeks thought women were very dangerous and tempting. If Odysseus never came in contact with Calypso or Circe he would have never had any affairs. If those affairs never started Odysseus would not have had an affair with Calypso for seven years. He also would not have had an affair with Circe meaning he would have returned to Ithaca sooner. His affairs were part of the reason for his delay. Things would have been different if Odysseus encountered more male obstacles because he could have fought them and would have won but from what we see Odysseus did not believe in physical abuse toward women, so he was also sexist. He did not believe in killing or hitting women. Throughout the book the only women he killed were his maids because they had sexual relations with the suitors. Therefore he could not kill or hit Circe or Calypso because they were good to him. If Odysseus did not encounter so many female obstacles he would have gotten to Ithaca quicker but he was an epic hero therefore he had to prove himself a true hero.

Challenges in Mozambique

MOZAMBIQUE’S CHALLENGES By Alina Sandra Silvi Abstract Mozambique, by its official name the Republic of Mozambique is a country in south-eastern Africa which in 1505 was colonized by Portugal. The country became independent in 1975 but in 1977 a civil war started and lasted for 15 years†¦ by the end an estimated one million lives were lost. However, lots of things have changed for Mozambique in a decade; â€Å"from being one of the poorest countries on Earth, it has joined a rare group of success stories† (Vines A. , 2004).Today, its economy is booming, absolute poverty has fallen and all is due to increased production in agriculture – the main source through which people sustain their livelihoods. â€Å"The country’s economic performance has been spectacular since 1994, making it one of the greatest recipients of foreign capital inflows in Africa. These inflows and increasing domestic growth enabled government expenditure on social and infrastructur e projects to be doubled. Investment has included the two billion dollars BHP – Billiton aluminium smelter – the largest single investment in Mozambique’s history† (Vines A. 2004) Introduction This report will analyze some of the problems that Mozambique is still facing because despite the positive aspects presented, Mozambique is still struggling to achieve the eight Millennium Development Goals. The paper will focus on three inequalities although all of them are interrelated and all need to be achieved equally for a sustainable development of the country. First of all, the eradication of absolute poverty and hunger will be evaluated because half of Mozambique’s population is still living below poverty line.Secondly, the achieving of universal education will be assessed because through education people become more informed and develop skills which can help them to improve their lives; someone once said, â€Å"Give a man a fish and he will eat for a day, teach a man to fish and he will eat for a lifetime† (Madi M. and Wilson E. , 2005). In the end, the report will look at the impact of HIV/AIDS and other diseases on people and at how they can be combated. 1. Extreme poverty and hunger Every day we hear on the news or read in the newspapers that more and more people are starving and live in extreme poverty.This is also the case of Mozambique, a rich country due to its natural resources, with an economy considered of huge potential but where people still live in unimaginable conditions and got to bed with their stomachs aching due to the lack of food. Lappe et al (1998) present in their book some of the ‘causes’ of the hunger and also prove that they are only myths†¦ myths which can be contradicted. For example, one of the myths says that there is not enough food in the world and that is why some people go hungry†¦ ut, in fact, the world today produces enough grain itself in order to feed everyone a nd to provide them with thirty-five hundred calories per day. The American Association for the Advancement of Science found in a study that 78% of all undernourished children under five live in developing countries with food surpluses (Lappe, F. M. et al, 1998). Also countries such as India, Africa and Bangladesh, where hunger is at a high level, export much more in agricultural goods than they import. All these facts led to a single conclusion: that food scarcity is clearly not the cause of hunger.The main conclusion of the book – World hunger: 12 myths (Lappe, F. M. et al, 1998) – is that hunger is driven by poverty because people are too poor to buy readily available food and all this requires political not agrotechnical solutions. Allen, T. and Thomas, A. (2000) stated, â€Å"Chronic hunger is related to poverty and a persistent failure to generate sufficient entitlements in a society†. The World Bank measures poverty by the percentage of people living below an income of one US dollar per day. (see appendix 1, fig. ) The proportion of the population living under the poverty line declined from 69. 4% in 1997 to 54. 1% in 2003. The main factor that led to such an improvement was the economic growth rate which was above 7% for much of the past decade. To continue the strong commitment and leadership proved since the achievement of PARPA I the Government of Mozambique have now implemented PARPA II which will be developed under the â€Å"areas of macro-economy and poverty, governance, economic development, human capital and cross-cutting issues† (Mozambique second MDG report, 2005). 2. EducationThe second Millenium Development Goal’s – Achieve universal primary education – target is â€Å"to ensure that, by 2015, all boys and girls are able to complete a full course of primary schooling† (Mozambique second MDG report, 2005). In 1975, when the Portuguese left the country, Mozambique’s only university lost most of its teaching staff and was forced to play its role in developing skilled manpower for the socialist experiment. The system of primary education in Mozambique contains two cycles: a lower level of five years (EP1) followed by two years of higher level (EP2).The net enrolment rate (NER) for EP1 increased substantially between 1997 and 2003, from 44% to 69. 4% (Mozambique second MDG report, 2005). Despite this progress Mozambique is still facing a high level of geographical and residential disparities, and also a gender gap – the NER for girls in EP1 was 66. 4% compared to 72. 4% among boys (Mozambique second MDG report, 2005). The completion rates in EP1 also increased from 22% in 1997 to 38. 7% in 2003, however, the country will not achieve the MDG target for 2015 if substantial and financial resources are not invested in the system.The World Bank stated in a report in 1985 that the role of literacy it is very powerful in determining a population’s level o f mortality and also suggested that â€Å"this factor carries far more weight than many others, including income growth† (Allen, T. and Thomas, A. , 2000) Female education also has an important role in providing good health because an educated woman is capable of creating a healthier environment for her family. This idea has been supported by two of the World Bank’s publications – one in 1983 and the other in ten years later (Allen, T. and Thomas, A. , 2000).In order to solve the education problem a first Education Sector Strategic Plan (ESSP I) was implemented for 1999-2003 period. The plan’s goal was to improve the education system in order to promote economic and social development and poverty reduction in Mozambique (Mozambique second MDG report, 2005). In 2005, the second ESSP was approved covering the period 2005-2009; its role is to continue the work of the first ESSP but also to strengthen it. 3. HIV/AIDS and other diseases The death rate of child ren under five years old in the least developed countries is 40% and the rate for people under 65 is 84% compared with only . 7% and 23% respectively in rich countries (Allen, T. and Thomas, A. , 2000) . All these deaths are generated by diseases attack, especially the infectious and parasitic ones. The greatest threats for Mozambique’s development are HIV/AIDS. From 1998 to 2004 the HIV/AIDS prevalence among adults has increased from 8. 2% to 16. 2% although it varies greatly between the three regions of the country. (see appendix 1, fig. 2) In 2003 1. 5 million Mozambicans had HIV/AIDS (8% of total population) the majority being represented by women (58%). Among those living with HIV/AIDS 5. 8% were children under 15 years old.An important thing to bear in mind is that just as HIV and AIDS generate poverty and inequalities so do poverty and inequality facilitate the transmission of HIV. This happens because people in poor areas do not have the necessary income in order to b uy condoms or an easy access to health facilities and HIV infection programmes. Today, HIV accounts for considerable mortality and morbidity and â€Å"the UN programme UNAIDS recently estimated that by the end of 1996 more than 23 million people worldwide were infected with HIV and more than 6 million people had died with AIDS† (World Bank, 1997).Moreover, HIV/AIDS facilitate the transmission of other infectious diseases such as tuberculosis (TB); the most vulnerable one being again the poor ones who live in overcrowded conditions and have very low incomes. In fact, â€Å"TB is now one of the leading causes of death among adults in many developing countries and it is estimated that it kills about three million people a year. The increase in fatal cases parallels the AIDS epidemic in many countries† (Allen, T. and Thomas, A. , 2000).In order to confront this problem, in 2002, a multi-sectoral National AIDS Council (NAC) was created to lead and coordinate the national re sponse to HIV/AIDS. The government also revised its National Strategic Plan to Combat HIV/AIDS and created a second one, for the period 2005-2009, that â€Å"will prioritise the following seven areas: prevention, advocacy, stigma and discrimination, treatment, mitigation, research and investigation and coordination of the national response† (Mozambique second MDG report, 2005). ConclusionThis report presented only three of the inequalities facing Mozambique when, in fact, there are much more and all of them are interrelated, creating a vicious cycle that needs to be broken in order to achieve a full and satisfactory development. The Secretary-General has outlined a number of priorities for UN action to sustain the development of all countries in Africa: * Regional structures must be strengthened; * Their economies have to be diversified and increase the promotion of ‘free-market’ and ‘free-trade’; * Promotion of a Green-Revolution by financing the de velopment of high-yield food crops etc. UN Chronicle, 1995) List of references: Allen, T. and Thomas, A.

What really Happened essays

What really Happened essays When someone views this picture for the first time there is usually a feeling of shock at what they see. This feeling is clearly understandable if you are just shown the picture by itself with no caption or background information. It is the lack of facts and truths that have caused this very photograph to be the center of so much controversy and debate. When this photo was taken from a video clip filmed at the bombing of Trang Bang in June of 1972 the correct version of the story was reported. Since then and in other journalist's stories the truth has become distorted over time and this photo has become an icon for the anti-war movement. Although this photo actually had very little impact on the decision to withdrawal troops and end our campaign in Vietnam it has had a profound impact on the American and Vietnamese public. This photograph was taken in June of 1972 by Nick Ut outside the small city of Trang Bang. The small girl with her clothes burned from her body shown running away from the ruin was Kim Phuc. The soldiers seen in the background are Army of the Republic of Vietnam soldiers. The fires in the background is napalm burning. These elements by themselves simply show a small moment in time captured on film. This moment frozen in time displays all the terrors and what is wrong with war. If we add into this mix irresponsible reporting with a public opinion already geared in the direction that our involvement in Vietnam was wrong we have a dangerous mix. What this dangerous mix has evolved into today is a gigantic misconception of what really happened in this frozen moment of time. This photograph not only has effected the American public it has also been used as propaganda against the South Vietnamese government. There have been many myths about this one specific photograph, some are understandable and some have been out right lies or media grabbers getting their moment in the spotlight. As reporters covere...

10 Chlorine Facts (Cl or Atomic Number 17)

10 Chlorine Facts (Cl or Atomic Number 17) Chlorine (element symbol Cl) is an element you encounter every day and need in order to live.  Chlorine is atomic number 17 with element symbol Cl. Fast Facts: Chlorine Symbol: ClAtomic Number: 17Appearance: Greenish-yellow gasAtomic Weight: 35.45Group: Group 17 (Halogen)Period: Period 3Electron Configuration: [Ne] 3s2  3p5Discovery: Carl Wilhelm Scheele (1774) Chlorine Facts Chlorine belongs to the halogen element group. It is the second lightest halogen, after fluorine. Like other halogens, its an extremely reactive element that readily forms the -1 anion. Because of its high reactivity, chlorine is found in compounds. Free chlorine is rare but exists as a dense, diatomic gas.Although chlorine compounds have been used by man since ancient times, pure chlorine was not produced (on purpose) until 1774 when Carl Wilhelm Scheele reacted magnesium dioxide with spiritus salis (now known as hydrochloric acid) to form chlorine gas. Scheele did not recognize this gas as a new element, instead believing it to contain oxygen. It wasnt until 1811 that Sir Humphry Davy determined the gas was, in fact, a previously unidentified element. Davy gave chlorine its name.Pure chlorine is a greenish-yellow gas or liquid with a distinctive odor (like chlorine bleach). The element name comes from its color. The Greek word chloros means greenish-yellow.Chlorine is the 3rd most abundant element in the ocean (about 1.9% by mass) and 21st most abundant element in the Earths crust. There is so much chlorine in the Earths oceans that it would weigh 5x more than our present atmosphere if it were somehow suddenly released as a gas.Chlorine is essential for living organisms. In the human body, its found as the chloride ion, where it regulates osmotic pressure and pH and aids digestion in the stomach. The element is usually obtained by eating salt, which is sodium chloride (NaCl). While its needed for survival, pure chlorine is extremely toxic. The gas irritates the respiratory system, skin, and eyes. Exposure to 1 part per thousand in air may cause death. Since many household chemicals contain chlorine compounds, its risky to mix them because toxic gases may be released. In particular, its important to avoid mixing chlorine bleach with vinegar, ammonia, alcohol, or acetone.Because chlorine gas is toxic and because its heavier than air, it was used as a chemical weapon. The first use was in 1915 by the Germans in World War I. Later, the gas was also used by the West ern Allies. The effectiveness of the gas was limited because its strong odor and distinctive color alerted troops to its presence. Soldiers could protect themselves from the gas by seeking higher ground and breathing through damp cloth since chlorine dissolves in water. Pure chlorine is obtained primarily by electrolysis of saltwater. Chlorine is used to make drinking water safe, for bleaching, disinfection, textile processing, and to make numerous compounds. The compounds include chlorates, chloroform, synthetic rubber, carbon tetrachloride, and polyvinyl chloride. Chlorine compounds are used in medicines, plastics, antiseptics, insecticides, food, paint, solvents, and many other products. While chlorine is still used in refrigerants, the number of chlorofluorocarbons (CFCs) released into the environment has dramatically declined. These compounds are believed to have contributed significantly to the destruction of the ozone layer.Natural chlorine consists of two stable isotopes: chlorine-35 and chlorine-37. Chlorine-35 accounts for 76% of the natural abundance of the element, with chlorine-37 making up the other 24% of the element. Numerous radioactive isotopes of chlorine have been produced.The first chain reaction to be discovered was a chemical reaction involving chlorine, not a nuclear reaction, as you might expect. In 1913, Max Bodenstein observed a mixture of chlorine gas and hydrogen gas exploded upon exposure to light. Walther Nernst explained the chain reaction mechanism for this phenomenon in 1918. Chlorine is made in stars via the oxygen-burning and silicon-burning processes. Sources Greenwood, Norman N.; Earnshaw, Alan (1997). Chemistry of the Elements (2nd ed.). Butterworth-Heinemann.

The Benifits of Quality Early Childhood Education by using curriculum Thesis Proposal

The Benifits of Quality Early Childhood Education by using curriculum and literature - Thesis Proposal Example Last four decades witnessed an increasing attention directed to the education of children who are under five (Barnett & Boocock, 1998). With ongoing changes in family structures and lifestyles, the number of children who are cared for by someone other than a parent has steadily increased. On the basis of information provided by Barnett and Boocock, estimates suggest that almost 65 percent of mothers with preschool children are in the labor force. In 1995, 59 percent of all preschool-aged children within the US were in preschool care and education programs on a regular basis, including 67 percent of three-year-olds and 77 percent of four-year-olds (Hofferth, Shauman, Henke, & West, 1998). According to the study carried out by West, Denton, and Germino-Hausken (1998), US Department of Education (Doe) found that 80 percent of all children beginning kindergarten in the fall of 1998 had been in child care on a regular basis, and about half continued to be in child care before or after sch ool. Suggesting that, currently, the vast majority of children within the US spend much of their day away from their parents, with most attending a center-based preschool program prior to kindergarten. As reported by Yarosz and Barnett (2001), center-based preschool programs in 1999, were frequently attended by preschoolers throughout the US, with program participation at 70% at age four and 45% at age three. As described by Yarosz and Barnett, center-based programs are mostly labeled as child care, preschool, day care, and nursery school and are operated under a number of different auspices, including churches, independent non-profit, for-profits, public schools, and Head Start. According to West, Hausken, and Collins (1993), regardless of how preschool programs are described and labeled, most parents perceive such programs as educational. Further explained by Yarosz and Barnett, augmentation in parental education as well as income is directly related to an increase in the rate of enrollment and participation of children in preschool programs. The finding holds true with greater government support for programs targeting children in low-income families (example Title XX or Child Care Works). Additionally, as reported by Yarosz and Barnett, findings suggests that parents are less likely to enroll children under three in center-based programs, as parents tend to view infant and toddler care as less likely to influence later educational outcomes. Moreover, the implementation of preschool programs in public schools has recently increased. According to information provided by the National Center for Education Statistics (NCES)
