Management Research and Consultancy Essay Example | Topics and Well Written Essays - 1500 words

The board Research and Consultancy - Essay Example It is self-evident, that the examples of HRM in family and non-privately-owned company are unique, in this manner it ought to have been exceptional to discover the distinctions in HRM designs between various privately-owned companies, to plot the central point that impact these conduct and the methods of making these practices work for organizations of little and medium organizations. The work takes note of, that the terms HRM is now and again utilized in the incorrect manner, to supplant the renowned term of Public Management. In any case, it ought to be recollected that HRM is to some degree distinctive circle of examination, than the PM is. Along these lines, as the work is aggregated at looking at the HRM examples of various types of little and medium undertakings, less consideration is paid to privately-owned company itself, as a brilliant case of abnormal and remarkable human relations inside every venture. Simultaneously, the current examination is an endeavor to fulfill the pressing requirement for considering the HRM forms in the little and medium firms; as such exploration has consistently been made for enormous enterprises. The significance of HRM in each firm, either huge, or little, isn't contended. It is one of the key ways for the turn of events and progress of any association. 2. Assess the writing audit and the way that the analysts have utilized it to set examination questions and structure of the task. The examination depends on a major number of artistic works, identifying with human asset practices and privately-run company as the monetary wonder. There is no contention about the reality, that it is simpler to oversee in the littler condition, and the examination identifies with crafted by Story and Guest (1987), which recommend, that the key ideas of any human asset the board are high adaptability, excellent, high joining and high duty, yet Guest's book was composed for the enormous organizations, and along these lines it is somewhat vague, regardless of whether his thoughts are relevant to the littler business; this issue needs further exploration. Unexpectedly, the Story's thoughts concerning the significant job of correspondence and rationale are pertinent for little privately-owned company, as the correspondence in any human relations plays one of the first, if not the main, job. The writing, picked for the examination, is rarely given to HRM in little firms, as this conversation has consistently needed consideration and intrigue, however it is comprehended, that the thriving of little firms, and fruitful HRM, as an extensive piece of this flourishing, is the principle incitement for the general monetary development. (Dundon, 2001) The writers, who have given their time and books to the HRM, never truly focused on the littler and medium business, basically laying out the need for such examination, without going further into the subject.

Accounting as an Information System, Hasstrengths and Weaknesses Free Essays

The Disadvantages of Accounting Information Systems 1. A bookkeeping data framework is intended for organizations to use for recording their budgetary exchanges. Data is entered, handled, put away and dispersed through this kind of framework. We will compose a custom exposition test on Bookkeeping as an Information System, Hasstrengths and Weaknesses or then again any comparable theme just for you Request Now Bookkeeping data frameworks have numerous advantages; in any case, there are likewise a few hindrances to them. Learning the System 2. Learning a bookkeeping data framework can frequently be troublesome and tedious. People must be prepared on a framework, and this can make an impediment organizations as far as time and labor. A bookkeeping data framework is comprised of a wide range of segments, and practically all frameworks are automated. Due to their multifaceted nature, a few people may discover them difficult to utilize. It can take weeks or months for an individual to comprehend a bookkeeping framework, and typically the individual despite everything doesn't see totally what the framework is able to do. On the off chance that the representative stops working at the association, it can take weeks or months, by and by, to prepare another worker. Loss of Information 3. Bookkeeping data frameworks are normally electronic. Along these lines, there is constantly a danger of losing data through force blackouts or framework crashes. At the point when this occurs, quite possibly all the data in the framework could be lost. Organizations avoid potential risk for this issue by sponsorship up their records normally and performing standard upkeep on all PC frameworks. They additionally introduce hostile to infection programming as another safety measure. In any case, none of these means wipes out the potential issue that may happen. Bookkeeping data frameworks store a company’s money related data for a considerable length of time. On the off chance that a framework crash happens, it makes a significant inconvenience the organization. All, or a few, data is lost, and there’s a possibility it might never be recuperated. Re-assessment 4. Organizations frequently change their method of working together to stay aware of the most recent patterns. To keep up in a requesting business world, these progressions may affect a bookkeeping framework. A bookkeeping data framework is hard to set up on the grounds that each organization is special in its own particular manner. So as to stay aware of changes, bookkeeping data frameworks must be rethought regularly. Changes frequently should be made in a framework so as to process data proficiently.

Completing your FAFSA and Budgeting COLUMBIA UNIVERSITY - SIPA Admissions Blog

Completing your FAFSA and Budgeting COLUMBIA UNIVERSITY - SIPA Admissions Blog Thanks to Cecilia Granda, Associate Director of Financial Aid, for this guest post.   The idea of budgeting makes everyone cringe. Picture days of peanut butter and jelly sandwiches followed by nights of staying at home staring at a spreadsheet wondering where all your money has gone. But take it from a lifelong New Yorker who has lived in the Upper West Side, Gramercy, Inwood, and the Bronx by creating budgeting plans, I have been able to continue to call New York my home, raise a family, create an emergency fund, and enjoy the occasional Sunday brunch. The FAFSA and federal student aid If you are a U.S. citizen or permanent resident applying to SIPA and would like to be considered for a scholarship, you must submit your FAFSA with your SIPA application.  The FAFSA for 2020-21 is available as of October 1st, so you can complete it before you submit the SIPA application. The SIPA school code is 002707. Be sure to input your 2018 income information; do not include your parent’s information. Once this is done, you will have at least put yourself in the running for any potential SIPA scholarship funding.   But don’t stop there.   Start researching external funding sources to determine if you are eligible.   Keep track of application deadlines and requirements so that you don’t miss opportunities. Photo: FAFSA Facebook page Budgeting For me, budgeting is all about planning ahead, self-awareness, and adjusting habits in order to save small amounts of money that can add up fast to help me reach my goal. When budgeting, I like to prioritize needs versus wants. Everyone’s priorities are going to be different. For graduate students the top three needs are clear: food, shelter, and education. The first step is an inventory check. How much money do you have? How much do you spend in one week or one month? Keep all your receipts and calculate how much you spent. Categorize your expenses between essential and discretionary; then priorities your expenses. If you are considering a graduate program, you can start early in transitioning your lifestyle from working to grad student. Next, set your goals. Once you’ve determined how much you have and how much you are currently spending, decide how much you need to save. Become familiar with the tuition and fees associated with each program youre considering. Consider how you will manage these costs and how much you need to save now in order to achieve your educational goals. You can start small by calculating how much you need to save on a weekly basis. It might be $50 a week, which becomes $200 a month, and turns into $2,400 a year. Once you find the right number, see if you can find ways to increase your weekly savings. One easy way to save, and a habit that you can bring to the big city, is shopping generic brands. Non-perishables like tissues, toilet paper, medicine, paper towels, toothpaste, toothbrushes, cleaning products, detergents, shampoo, and soap are all great options. This small change in purchasing can save you hundreds of dollars. Now you want to be sure your able to track and not touch your savings. Be honest with yourself. This is where self-awareness comes in handy. Can you set aside $50 each week? Do you need a budgeting app like Mint or Digit that will help you manage your money, track your spending, and force you to save? You might decide to give yourself an allowance for the week, only spend the amount in your wallet, and not use a credit card. Find a method that you can stick to and hold yourself accountable. Remember, you don’t have to do this alone. You most likely have friends who have similar financial goals. Make a pact! Agree to only go out to dinner once a week. This will help you transition to graduate school life. Many Seeples are very responsible about their finances. Some share a Costco membership so they can buy food in bulk and split the quantities (there’s a Costco in East Harlem). Others put together meal prep plans, share recipes, and organize pot lucks. One great thing about Seeples is they come from all over the world and have wonderful cuisine to share! I hope this information is helpful and don’t fret if you aren’t able to do it all. Even the smallest change in habit or savings will help you prepare for your next step. *Disclaimer: The applications identified in this article are based on personal recommendations, and SIPA is not receiving any form of compensation for mentioning them in this blog post.

Enzyme Lab Report - 1676 Words

The purpose of the enzyme lab conducted was to observe the chemical composition of cells. In order to do so we tested for the presence of organic molecules. Molecules are what forms when atoms bond together. Organic molecules of cells include proteins, carbohydrates, and lipids, which are composed of smaller molecules known as monomers and polymers. Polymers are joined monomers. A chemical reaction links monomers together occurs and releases a water molecule, this is called dehydration synthesis. Hydrolysis separates polymers into monomers by using water to break bonds. Organic catalysts called enzymes are proteins that increase the speed of a chemical reaction. In the lab we used Biuret reagent to test for proteins, iodine solution to†¦show more content†¦When Benedict’s reagent was added to the glucose solution it turned to a dark orange-red, indicating a high sugar concentration. Next we added Benedict’s reagent to the starch solution which remained blue, indicating no sugar presence. The onion juice also turned a red-orange color as a reaction to the addition of Benedict’s reagent indicating a very high sugar concentration. Lastly, when Benedict’s reagent was added to potato juice a yellow-orange color was visible, indicating a moderate concentration of sugar. Our following experiment of the lab tested for lipids. We placed a drop of water on a piece of brown paper and a drop of water on a separate piece of brown paper. Observation after allowing the drops to sit on the paper for 15 minutes included that the water remained bead on the paper and subject to evaporation indicating the absence of lipids. On the other hand, the oil drop sample was absorbed by the paper and the paper became translucent. To further study lipids, we experimented with the emulsification of lipids. An emulsifier has both polar and non polar ends, which change the polarity and causes fat to disperse in water. Two test tubes were used. The first was marked at three and four centimeters. The second labeled at one three and four centimeters. In tube one we added water to the three centimeters, and filled oil to the marking on the center tube and shook the tube.

Statement of Purpose Santosh G Vattam MS Free Essays

Statement of purpose Santosh G Vattam MS, Embedded Systems (CIS), May 2012 Research Interest I am a Master of Science and Engineering student majoring in Embedded Systems from University of Pennsylvania, graduating in May 2012. I am interested in embedded systems modeling and model based code generation. This interest has developed thanks to my research project with Prof. We will write a custom essay sample on Statement of Purpose Santosh G Vattam MS or any similar topic only for you Order Now Insup Lee as well as the Embedded and Cyber Physical Systems and the Principles of Embedded Computation courses I took at Penn with Prof. Insup Lee and Prof. Rajeev Alur respectively. The Embedded and CPS course involved modeling and implementation of a pacemaker, while the Principles of Embedded Computation course provided the much needed theoritical foundation for developing embedded system models and verifying and validating thus developed models. Research projects In Jan 2011, I started working on the Medical Device Dongle(MDD) Project with Prof. Insup Lee. The idea was to make patient monitoring, patient centric rather than device centric by developing a standards-based interface for medical device interoperability. We decided to use the existing device interoperability standard – IEEE11073-PHD with slight modications. I implemented the rst prototype of the IEEE11073 Manager and Agent state machines. We later encountered the problem of providing a medium for using the services of the MDD and thus we designed and implemented an interface to sit on top of the MDD. We have since presented our work at the Wireless Health Conference 2011, San Diego, CA and at Embedded Software Week Android competition, Taipei, Taiwan. We shall also be presenting at the International Health Informatics Symposium, Miami, FL in Jan 2012. Prior to this, I have worked on the Coverage Analysis of RTEMS(Real Time Executive for Multiprocessor Systems) as part of Google Summer of Code 2009 and mentored another student in 2010 for the same project. This project was my rst step into the embedded world. I wrote test cases to validate that every single line of object code generated was executed. I worked on the RTEMS-core codebase and in 2010 I mentored a student to work on the extended codebase. Research focus I would like to focus my research on model based code generation and validating the conformation of code to the model on which it was based. This is a problem that I have come across while working on the MDD project. We have based our design on the IEEE11073 architecture but there are no open implementations of it through which we can verify our implementation. There are certain validation tools but these just analyze the packet structure of the 11073 packets but not the ow of these packets within the network of devices. I am partly tackling this problem through my Masters thesis by writing test cases to validate the exchange of the right packets. This method, however, does not provide insight into the internal state ow of the code. I would like to study, n depth, the ways of validating code to the state model. I believe that by pursuing a PhD I shall not only gain the necessary skill set to tackle this problem, but also the insight of looking at unstructured data and obtaining structured information from it. Prof Insup Lee and his team at the PRECISE Center work on model based design and validation in the medical device domain. I have been working with Prof. Insup Lee and his team for close to a year now on the MDD project. I believe that the environment and the expertise at the PRECISE Center will provide me with the encouragement and the academic stimulus to excel at my research.

To investigate how surface area effects the rate of reaction in Calcium Carbonate Essay Example

To investigate how surface area effects the rate of reaction in Calcium Carbonate Essay This experiment is working on the theory of diffusion. Diffusion is the movement of particles. Three main things effect the rate of diffusion:- The distance of particles. Diffusion is quickest in gases as gas has a larger space between molecules making diffusion occur faster.- The energy of particles. The temperature effects the rate of reaction because the higher the temperature the faster the reaction.- The mass of particles. The effect of mass is caused by the relationship between the speed of particles and their temperature.Diffusion occurs in all the states of matter. However they most noticeably take place in liquids and gases. An example of this is Brownian Motion. Robert Browning noticed that when looking under a microscope pollen grains were moving in a random way. This movement is explained by assuming water molecules were hitting the pollen grains in a random way causing the pollen to move erratically.Brownian motion and diffusion provide evidence to support the kinetic th eory. The kinetic theory is kinetic energy cannot be created loss or destroyed. Instead it is converted to another form of energy. Particles have kinetic energy the energy of movement. Gases have the greatest kinetic energy and solids the least.This experiment also works on the Collision theory. Chemical reactions can be explained by the collision theory. For particles to react they must collide and they must have sufficient energy to react. There are many factors that effect the rate of reaction.- If the size of the reacting particles is decreased, there is more surface area available for reacting and so the speed of reaction increases.- When a solution becomes more concentrated, the number of particles present in the solution increases.- Increasing temperature increases the speed at which the particles move. Thus speeding up the reaction.Factors effecting the rate of reactionI am looking at the pros and cons of investigating each factor on the rate of reaction.CatalystsPro- This speeds up the rate of reaction by helping bonds between atoms to break and form more easily. It is also reusableCon- The problem with this would be it makes this an unfair experiment unless you carefully measure out the same amount of catalayse.TemperaturePro-Heating it would speed up the experiment, and keeping it cold would slow it down. This is because if you heat it up it makes the water particles collide and move about more breaking up the marble chips faster.Con- Heating it is can be very dangerous and it could make the test tube explode.ConcentrationPro- You can see a definite difference if you use different concentrations.Con- It can be quite expensive using a large concentration of the chemical.Surface areaPro-Its inexpensive, practical and not dangerous.Con-It is a little inaccurate if not measured in exact sizes.ChoiceI have chosen to test the rate of reaction on surface area. This is because of all the reasons above can get around the con by using roughly the same size c hip.PlanPre-testIve carried out the pre-test using different quantities of calcium carbonate and different quantities of Hydrochloric acid. The quantities with long and most vigorous reaction will be the quantity I will use in the investigation because it will give me a good set of results.ApparatusMedium sized Calcium carbonate chipsThree Test tubesScalesTimerMethod1. Measure 5g of calcium carbonate and measure 20ml of Hydrochloric acid.2. Put the calcium carbonate in the test tube, pour the acid in and quickly start the timer.3. Observe every ten seconds the weight of the marble chips and acid. Stop when the same weight occurs four times in a row.4. Repeat steps 1-3 with 10g of calcium carbonate and 40ml of hydrochloric acid.5. Repeat steps 1-3 with 15g of calcium carbonate and 60ml of hydrochloric acid.Results5g and 20ml of hydrochloric acid-Fast reaction and not very vigorous.10g and 40ml of hydrochloric acid-Long reaction and very vigorous.15g and 60ml of hydrochloric acid-Long reaction and quite vigorous.Conclusion:This pre-test showed me that the best results to use in my investigation would be 10g and 40ml of Hcl. This was because this was the most vigorous and the longest results without wasting too much Hcl and Calcium carbonate.EvaluationThis pre-test was quite accurate. There was only one problem, acid was loss to the spitting I will use cotton wool to cover the top. The reason I will not use a cork stop is this will prevent all gas escaping. I will use wool because this will let gas escape but not acid.PredictionI predict that the large marble chips are going to take the longest to diffuse. The medium a fair amount of time to diffuse and the smallest chips will be the quickest to diffuse. I know this by my theory on diffusion and the collison theory. I know that If the size of the reacting particles is decreased, there is more surface area available for reacting and so the speed of reaction increases.EquipmentSmall, medium and Large marble chips.C onical flaskElectronic ScalesMeasuring cylinderHydrochloric acidCotton woolMethod1.

The loss of mass is the largest in the big chips. However the loss in the medium chips is not as large as the small chips. The small chips loss of mass was consistent in the experiment. This is because the larger the surface area the faster the rate of reaction is. As you can see my results link back to my planning. In my planning it was said that if the size of the reacting particles is decreased, there is more surface area available for reacting and so the speed of reaction increases. This is true and matches up to my results.EvaluationMy experiment worked extremely well in the plan but didnt work a s well when I did the whole experiment. My results were not as accurate as expected. The flaws in my experiment were probably due to the following factors:* Timer wasnt started at exactly the time the marble chips went in.- To rectify this I will observe more carefully when to start the timer.* The cottons mass was not taken and deducted at the end.- I should next time take the mass of the cotton* Hydrochloric acid was not measured out properly.- I could maybe weigh the amount of hydrochloric acid used on some electronic scales.* Lots of people were in the room and were all walking about. People could have knocked the table causing the mixture to be swirled around a bit. Making the results slightly unfair.- I could possibly of done the experiment in a quite room on my own without distractions and lots of people walking about knocking the table.* The Calcium carbonate chips were not all the same size.- When choosing the chips I could of looked for similar sized chips to use so surfac e area was still the same.However even with these factors taken into account the experiment gave me my expected results. So I presume that these flaws in my experiment did not really effect the results.To further on my work I could look at how a catalyst would effect the rate of reactions. I could also look at all the other factor such as temperature and concentration and how they effect the rate of reaction.

One important question to ask is, "Were the European colonists/missionaries wrong in the fact that they invaded a society that did not want to be changed?" The Europeans condemned the Ibo people as "barbarians" and "savages," which were justifiable by the European religious and social definitions of the words. The similar mentalities are present in the three quotes by F. Hegel, R. Burton, and S. Baker. Ultimately, the Europeans began a moral crusade to "save" the barbarians from what they saw as their own ultimate "demise." In Things Fall Apart, Chinua Achebe presents to us the destruction of a traditional native culture, the weakening of Ibo spirituality, as well as the death of the tribe's livelihood. He reveals that the ever apparent cause can be found in a seemingly good intended mission, acting as a gateway for the intrusion of a foreign government. Throughout the failures and defeats of this society (in response to European colonialism) Achebe shows us the true vision of these African civilizations, and the African Mind, Spirit, and Presence is celebrated. The ideological system of colonization has been a violent destructive force on the world, as we know it. Slavery, murder, violence, rape, and torture of non-European peoples was the cruel reality of colonization. European nations, with the motives of sheer greed, brought Africans into slavery. This hostile take over was rationalized through the racist ideology that native peoples were inferior savages: "He would appear rather a degeneracy from the civilized man than a savage rising to the first step were it not for his total incapacity for improvement." (R. Burton) In the eyes of the Europeans, their idea of "improvement" was a society that was a match to theirs, one that they could actually live in. This crusade was as unjustified at the turn of the century as it would ...

10 Interesting Facts About Nelson Mandela

10 Interesting Facts About Nelson Mandela Nelson Mandela will forever be remembered for the key role he played in dismantling South Africa’s system of racial apartheid. The activist and politician, who died on Dec. 5, 2013, at the age of 95, became an international symbol of peace and tolerance. While Mandela is a household name across the globe and hes been immortalized in motion pictures documentaries and books, many aspects of his life aren’t particularly well known to the American public. This list of interesting facts about Mandela’s life help to illuminate Mandela, the man. Discover the impact his father’s death from lung cancer had on him as a youth or  why Mandela, a good student in spite of his humble origins, was expelled from university. Born July 18, 1918, Mandela’s birth name was Rolihlahla Mandela. According to Biography.com, â€Å"Rolihlahla† is often translated as â€Å"troublemaker† in the Xhosa language, but strictly translated, the word means â€Å"pulling the branch of a tree.† In grade school, a teacher gave Mandela the Western first  name of â€Å"Nelson.†The death of Mandela’s father from lung cancer was a huge turning point in his life. It resulted in the then 9-year-old’s adoption by Chief Jongintaba Dalindyebo of the Thembu people, which resulted in Mandela leaving the small village he’d grown up in, Qunu, to travel to the chief’s palatial home in Thembuland. The adoption also allowed Mandela to pursue his education at institutions such as the Clarkebury Boarding Institute and Wesleyan College. Mandela, the first in his family to attend school, proved not only to be a good student, but also a good boxer and track runner.Mandela pursued a Bachelor of Arts degree at the University College of Fort Hare but was expelled from the institution because of his role in student activism. This news upset Chief Jongintaba Dalindyebo, who ordered Mandela to return to school and renounce his actions. The chief also threatened Mandela with an  arranged marriage, causing him to flee to Johannesburg with his cousin and pursue a career on his own. Mandela suffered the losses of two close family members while imprisoned. His mother died in 1968 and his eldest son, Thembi, died the following year. Mandela wasn’t permitted to pay his respects at their funerals.Although many people associate Mandela with his ex-wife Winnie, Mandela actually married three times. His first marriage, in 1944, was to a nurse named Evelyn Mase, with whom he fathered two sons and two daughters. One daughter died as a baby. Mandela and Mase split in 1955, formally divorcing three years later. Mandela married social worker Winnie Madikizela in 1958, fathering two daughters with her. They divorced six years after Mandela’s release from prison for his anti-apartheid activism. When he turned 80 years old in 1998, Mandela married his last wife, Graà §a Machel.While in prison from 1962 to 1990, Mandela wrote a secret autobiography. The contents of his prison writings were published as a book called Long Walk to Freedom in 1994.Mandela reportedly received at least three offers to be set free from prison. However, he declined each time because he was offered his freedom on the condition that he reject his earlier activism in some way. Mandela voted the first time ever in 1994. On May 10 of that year, Mandela became South Africa’s first black elected president. He was 77 at the time.Mandela not only fought against racial apartheid but also raised awareness about AIDS, a virus that has ravaged scores of Africans. Mandela’s own son, Makgatho, died from complications of the virus in 2005.Four years before Mandela’s death, South Africa would observe a holiday in the activist’s honor. Mandela Day, celebrated on his birthday, July 18, marks a time for people in and outside of South Africa to serve charitable groups and to work towards world peace.

Justification Report Part 2 Assignment Example | Topics and Well Written Essays - 500 words

Justification Report Part 2 - Assignment Example Miller Park construction in Milwaukee which failed to take the equipment efficiency guidelines of OSHA seriously exceeded its deadline by one full year. Their crane collapsed killing three workers on the spot. This caused them unnecessary law suit, loss of talent, labor issues and the construction cost exceeded enormously. Miller Park projects total budget was $413.9 million. This was 28.5% higher the estimated amount due to the one year delay. The crane repair costs and compensation accounted for $100 million. OSHA has reported four potentially dangerous accidents prior to the crane fatality. But the construction company ceased to lend ears to them causing this massive loss of money and man power. Paul Brown stadium was completed in 2.5 years. Its proposed completion budget was $453 million. The project was completed within the proposed amount on the given deadline without any casualties. Construction sites being highly vulnerable places to work, the project recorded a total of 92 minor accidents, 16 of which stalled work causing delays in the building construction. But, severe implementation of strict safety measures saved them nearly $4.6 million and loss of life. The worker compensation went into speeding up the work making up for the delays. OSHA states, implementing the safety measures strictly helped the project save nearly 58% of the money set aside to handle accidents and work place injury. A common debate arouse in this comparison as to why the Millers Park project was initially assigned very little amount for construction. While both the projects involved nearly the same features, Mitsubishi Heavy Industries America, Inc. and Lampson International Ltd agreed to give only $322 million to the Danny’s construction company. This led to compensation in employee safety and use of age old equipments leading to massive losses. Hence, the US government fined Mitsubishi heavily than the other two companies ($240,500). This proves awareness and education

The Death of Socrates Assignment Example | Topics and Well Written Essays - 750 words

The Death of Socrates - Assignment Example â€Å"The Death of Socrates† was completed in 1784 by Jacques-Louis David. David’s painting is a fine example of academic art which was a prevalent form in his day and age. The work was commissioned by the Tredaine de Montigny brothers, both of whom were active supporters of open public discussions and the free market system. This work of David’s would, ultimately, become an image of inspiration during the French Revolution.("Boston College") Academic artists rely on some very specific elements in order to qualify within the discipline. Firstly, it must contain historical relevance. The major subject of the work must contain a â€Å"sense of universal experience† within heroic terms; and nothing is allowed to distract from the subject or events that are being represented.(Goldstein 103) Socrates was a man of differing ideals and inspiring orations that earned him the accusations of being disruptive and of corrupting the Grecian youth. He was, ultimately, p ut on trial for this â€Å"crime† and found to be guilty. He was given the option of banishment or death by the consumption of hemlock. He accepts death rather than give up his principles. ... There are six people on either side of the philosopher. This includes the three individuals, one of which is Socrates’ wife, that are exiting up the distant stairs. The balance uses perspective that prevents the small, confining cell space from becoming overcrowded and helps keep the overall focus upon the main subject. The use of the neutral brown wood and gray stone has little texture, the majority of texture, as well as, color come from the people presented. Blue, rust, and yellow fabric is being worn repeatedly throughout the work, including by those exiting on the stairs. This retains the connected nature of everyone in the work. After all, in this style nothing can detract from the subject. This color continuity guarantees the perception that everyone is there or was there because of Socrates. The people on the stairs are not mistaken for people visiting another condemned prisoner. The only other character present that is even remotely distinguishable from the rest is, P lato, who is, also, wearing white robes. However, his robes remain more heavily shadowed. The light does not reflect as brightly upon his robes nor upon his skin as it does upon his mentor. Unity is extremely important within academic art, as well as, relevant in any piece of art. Unity is responsible for achieving an air of commonality within the end result and provides a sense of harmony of all the elements present.(Jirousek ) We know that all the individuals in â€Å"The Death of Socrates† belong there. We can look upon the environment and wardrobe and we accept that a moment of Grecian history has been captured. Everything appears and feels right. The intended function of the work and the artist’s purpose in creating it plays a huge role in the overall unity of the piece, as well.

Current Air Quality Trend In Malaysia

Current Air Quality Trend In Malaysia Dimitriou and Christidou (2007) mentions air pollution is one of the most pressing global environmental problems that threaten the wellbeing of living organisms, leading to a loss of biodiversity or disrupting the function of the environment as a system. Air pollution occurs as a consequence of natural processes as well as human activity (anthropogenic). Examples of natural causes of air pollution include volcanic eruptions, forest fires and windblown dust. Anthropogenic air pollution from sources like motor vehicles and industries continues to be a serious harm to human health and welfare is more likely, namely the more densely populated urban areas. The health effects of air pollution have been reported in research studies over the past 30 years. These effects include respiratory diseases such as asthma, cardiovascular diseases, changes in lung function, and death. Colls (1997) reported particles in the atmosphere primary or secondary, solid or liquid. They come into the atmosphere, and leave it again by a wide variety of routes. Particulate matter is characterized by its physical and chemical properties Nader (1975). In addition, particle size and particle composition are characteristic that play a significant role in the assessment of health effect. In response to this information, regulatory agencies with a mandate to protect public health must now consider how to implement monitoring networks that will allow measuring the particulate matter concentration. In recent years, a increasing of number of monitoring system for particulate matter (PM) are available and are wide ranging in type, cost, flexibility and accuracy. According to Kingham et al. (2006), accurate and reliable monitoring of PM aerosol in the respirable size fraction ( In 2001, Chung et al pointed about traditional monitoring networks (Continuous Aerosol Mass Monitor, Integrating Nephelometer, Tapered Element Oscillating Microbalance) for airborne particulate matter. A small number of past studies have evaluated the tapered element oscillating microbalance (TEOM) and a series of manual gravimetric methods (Allen et al., 1997, Ayers, 2004, Cyrys et al., 2001, Hauck et al., 2004, Williams et al., 2000) but fewer still have compared other commercial monitors (Baldauf et al., 2001, Chung et al., 2001, Heal et al., 2000, Monn, 2001, Salter and Parsons, 1999). CURRENT AIR QUALITY TREND IN MALAYSIA There are 52 National Air Quality Monitoring Stations (AQMS) in Malaysia, function to monitor continuously 5 major pollutants, namely Particulate Matter (PM10), Ozone (O3), Sulphur Dioxide (SO2), Nitrogen Dioxide (NO2) and Carbon Monoxide (CO). For the northern region of Malaysia (Perlis, Kedah, Pulau Pinang and Perak), the overall air quality levelwas lies between good to moderate. However, there are curtain places (Tanjung Malim, Alor Star and Sungai Petani) recorded unhealthy level of the day especially in the mid of the day till late afternoon due to high concentration of ground level ozone (O3). In tanjung Malim, one unhealthy day was recorded due to high level of particulate matter (PM10) Air Pollutant Index (API) system were used in reporting the air quality status in Malaysia. The API compute from the monitoring of Ground level Ozone (O3), Carbon Monoxide (CO), Nitrogen Dioxide (NO2), Sulphur Dioxide (SO2) and Particulate Matter of less than 10 microns in size (PM10). Air quality status can be categorized in five main level (good, moderate, unhealthy, very unhealthy and hazardous as in Table 1.1. Table 1.1 Malaysia : Air Pollution Index (API) (Malaysia Environmental Quality Report 2011, DoE) API Air Quality Status DoE in Malaysia Environmental Quality Report 2011 highlights the annual average of PM10 was 43m3 , but was slightly increased compared to 2010 (39m3 ). However, for both year (2010 and 2011) value still below the Malaysian Ambient Air Quality Guidelines value (50m3 ). The trend of the annual average levels of PM10 concentration in the ambient air between 1999 and 2011 complied with the Malaysian Ambient Air Quality Guidelines as shown in Figure 1.1 and Figure 1.2 shows the trend based on land use categories (Urban, Sub Urban, Background and Rural). MONITORING METHODS AND INSTRUMENTS The underway monitoring of airborne particulate matter in the ambient atmosphere is mainly for determination of the mass of the particle. The methods used for monitoring of concentration of PM can differ and are very dependent upon the aim of monitoring, sites, monitoring problem and resource that available during monitoring period. Usually, monitoring is to determine the concentration of total suspended particulate (TSP) and suspended particulate matter (SPM) have become outdated with the awareness that PM effects varies depending on sizes of the particle. QUARG (1996) pointed that the latest method of monitoring (gravimetric and direct reading method) are designed to determine the concentration of particle in the different sizes (PM10 and PM2.5). Table 1.2 displays the examples of the instrument for PM10 monitoring and the detection methods. Table 1.2 Examples of instruments used in PM monitoring Instrument Principle of detection Beta Attenuation Monitor (BAM) The beta ray sources used in BAM are 14C. Directly measured the particle based on relationship between beta ray attenuation to particle mass. Depends on the near exponential decrease in the total number of beta particle transmitted through a thin sample as the density increase (William et al., 1993) The gravimetric method that only the mass of particle can be affect the detector not by the size of distribution, physical size, shape or either by chemical composition (Chow et al., 1996) Tapered Element Oscillating Microbalance (TEOM) Tapered hollowed channel will act as a gateway where the particles are collected on a filter. For minimum thermal expansion that occurred at the tapered channel, the sample area is maintained at 50 °C. Thermal expansion may affect the oscillation frequency and might be reduce the total amount of particle bound water. DustTrak 8520 Hands carry instrument and highly portable direct reading monitor. Using light scattering laser to detect the particles. Particles scattered the light which is from laser diode drawn through a constant stream. Liu et al., (2002) mentions the amount of light scatter find out the particles mass concentration. PROBLEM STATEMENT In Malaysia, PM10 monitoring was conducted by Alam Sekitar Malaysia Sdn. Bhd. (ASMA). Md Yusof et al (2010) lists two instruments used for monitoring are high volume sampler (HVS) and beta attenuation monitor (BAM). BAM is the standard instrument used by Department of Environment (DoE) to measure particulate matter in 51 monitoring station in Malaysia. Air quality of these new areas cannot be monitored and observed due to the lack of monitoring stations of air quality. To develop these new monitoring stations, definitely it will be costly and need good maintenances. Additionally, air quality at the rural areas also cannot be monitored. Therefore, a new alternative instrument such as Direct Reading Monitors (DRM) will enable air pollutants to be monitored more comprehensively. Even though DoE has set up their monitoring station, the number of monitoring stations is limited. With the use of simple instruments and cost effective, the air quality in areas without monitoring stations can be monitored and assessed. For this study, direct reading monitor (DRM) was used to monitor PM10 concentration at selected stations. However, PM10 concentration recorded using DRM and BAM was different. This is due to different detection method between both instruments (DRM used laser and BAM used beta ray) and response time for DRM was set to one minutes, while BAM records hourly PM10. In addition, the mobile factor that is owned by DRM is also affecting the reading. Therefore, an appropriate coefficient needed to make sure the reading obtained from the DRM is the same as the reading derived from the BAM. OBJECTIVES The objective of this project is:- To estimate coefficient that relates DRM and BAM by using regression techniques. To investigate the best coefficient based on performance indicator. To determine the influence of meteorology on PM10 concentration. SCOPE OF STUDY In Malaysia, Beta Attenuation Monitor (BAM) is the standard instrument used by DoE to measure particulate matter in 52 monitoring stations. This instrument automatically measures and records hourly particulate mass concentration in ambient air. It uses beta ray attenuation to calculate collected particle mass concentration units of  µg/m ³. For this study, Direct Reading Monitor (DRM) was used to monitor PM10 concentration at Air Quality Monitoring Station (AQMS) conducted by Alam Sekitar Malaysia (ASMA). The station selected for this research is Prai and Seberang Jaya. Both stations are situated in the north part of Peninsular Malaysia. They are many researches comparing the mass concentration results of the BAM and gravimetric methods. Salminen and Karlsson (2003) reported the agreement between PM10 concentration measured by BAM and gravimetric method. PM10 concentration recorded by the DRM was compared with data monitored using BAM provided by DoE. Three method of linear regression was used to investigate the relationship between the DRM and BAM monitoring record which is method of ratio, method of quartile and method of quantile. Performance indicators were used to evaluate the goodness of fit for the ratio,quartile and quantile method to determine which method is the best.

CHAPTER 2 LITERATURE REVIEW 2.1 INTRODUCTION Sherman (2003) defined air pollution as the presence of undesirable levels of physical or chemical impurities. Many organization such as the World Health Organization (WHO, 1999) recognized particulate matter (PM), carbon monoxide (CO), nitrogen dioxide (NO2), ozone(O3), lead (Pb) and sulfur dioxide (SO2), as classical pollutants presenting a hazard to sensitive populations. Air pollution now becomes an increasing source of environmental degradation in the developing nations of East Asia (Alles, 2009). The air pollution in Malaysia has not reached a critical level as in other metropolitan areas in Asia, like Jakarta or Manila. (Malaysian German Technical Cooperation, 2000). However; even outside extreme haze periods, pollution levels increased despite tight regulations and this is added by the increase in the number of vehicle, distance travelled and growth in industrial production. Air quality in Malaysia is a major concern as the nation forged ahead to become an industrialized nation by the year 2020. The Malaysian Air Pollution Index (API) is obtained from the measurement of PM10 and several toxic gases such as SO2, CO, NO2, and O3. The air quality status in Malaysia is determined accordingly to API which indicates the level of pollution in the atmosphere. The API system of Malaysia closely follows the Pollutant Standard Index (PSI) system of the United States of America. According to Department of Environment, based on the Air Pollutant Index (API), the overall air quality for Malaysia in 2010 was between good to moderate levels most of the time. The overall number of good air quality days increased in 2010 (63 percent of the time) compared to that in 2009 (56 percent of the time) while remaining 36 percent at moderate level and one percent at unhealthy level. However, peatland fires resulting in transboundary air pollution that occurred in the Southern Asean region in the month of October resulted in a short spell of haze episode in the southern part of Peninsular Malaysia (DoE, 2009 DoE, 2010) DoE also reported that the overall air quality of the northern region of the West Coast of Peninsular Malaysia (Perlis, Kedah, Pulau Pinang and Perak), was between good to moderate most of the time. However, Tanjung Malim and Tasek recorded four unhealthy days and one unhealthy day, respectively. The pollutants of concerned were ground level Ozone (O3) and PM10. 2.2 AIR QUALITY MONITORING IN MALAYSIA In order to ascertain the quality of the environment in Malaysia, the Department of Environment (DoE) regularly monitor the air quality. The air quality monitoring, which involves measurements of total suspended particulates, atmospheric lead and dust fallout, are conducted at 52 monitoring stations (Figure 2.1 and 2.2) categorised as industrial, urban and sub urban areas (DoE, 2010). In addition to the 52 stations in the National Continuous Air Quality Monitoring Network, manual air quality monitoring stations using High Volume Samplers were also established at 14 different sites for measuring total suspended particulates, particulate matter (PM10) and heavy metals such as lead. A continuous automatic monitor which gives instantaneous measurements of gaseous pollutants such as CO, SO2, oxides of nitrogen and ozone, as well as suspended particulate matter and total hydrocarbon used as the monitoring equipments by the DoE to assess air quality (Abdullah, 1995). The air quality status is reported in terms of Air Pollutant Index (API). The air pollutants used in computing the API are ground level ozone (O3), carbon monoxide (CO), nitrogen dioxide (NO2), sulphur dioxide (SO2) and particulate matter of less than 10 microns in size (PM10). The API is categorized as good, moderate, unhealthy, very unhealthy and hazardous. 2.3 SOURCERS OF PM10 The US EPA defines particulate matter (PM) as a mixture of solid particles and liquid droplets found in the air. PM can be in sizes or colors large or dark enough to be observed or it can be so small that an electron microscope is required to distinguish it. According to Fierro (2000), coarse particles (PM10) have an aerodynamic diameter between 2.5 µm and 10 µm. They are formed by mechanical disruption (e.g. crushing, grinding, abrasion of surfaces), evaporation of sprays, and suspension of dust. PM10 particles are small enough to be inhaled and accumulate in the respiratory system (Colls, 1997). Particulate matter can come from many sources. Generally, any activity which involves burning of materials or any dust generating activities are sources of PM. Some sources are natural, such as volcanoes and water mist (Bates, 1995). PM is introduced to the air through both natural and human causes (Harrisonu Yin, 2000). PM from specific sources typically follow short term and long term (seasonal) trends (Yatin et al. 2000). For example, space heating generates more combustion related PM emissions during the cold seasons while, at the same time, snow cover can inhibit PM emissions from the soil. Quality of Urban Air Review Group (1996), published the report in which they describe that primary particles are those directly emitted to the atmosphere from sources such as road traffic, coal burning, industry, windblown soil and dust and sea spray. On the other hand, secondary particles are particles formed within the atmosphere by chemical reaction or condensation of gases, and the major contributors are sulphate and nitrate salts formed from the oxidation of sulphur dioxide and nitrogen oxides respectively. The primary sources of PM in Malaysia, are motor vehicles diesel trucks, industrial emissions, agricultural, slash and yard waste burning, and even exhaust from lawn mowers and boats (Department of Environment, Malaysia, 2010). PM concentrations tend to be especially high in area with greater population density, nearby industries or agriculture, or where local topography or weather conditions contribute to air stagnation. 2.3.1 Traffic Vehicular particle emissions are the result of a great many processes, an example combustion products from fuel and oil, wear products from brake linings, tyres, bearings, car body and road material, and the resuspension of road and soil dust (Laschober et al. 2004). Traffic is an effective source of both fine and coarse mode primary particles, condensable organic gases, and a major source of nitrogen oxides that then form secondary nitrate aerosols. Particles of condensed carbonaceous material are emitted mainly by diesel vehicles and poorly maintained petrol vehicles (Vardoulakis et al. 2003). Diesel exhaust particles have been shown to display a multimodal size distribution (Kerminen et al. 1997) and are mainly carbonaceous agglomerates below 100 nm in diameter, whereas particles emitted by gasoline vehicles are also mainly carbonaceous agglomerates but considerably smaller, ranging from 10 to 80 nm (Morawska and Zhang 2002). Particulate matter originating from traffic can be pres ent at elevated concentrations especially during high traffic density and poor dispersion conditions, e.g. in street canyons, which can lead to high human exposures to traffic-related pollutants (Vardoulakis et al. 2003). Identification of traffic related particulate matter in source apportionment studies has become difficult due to phasing out of Pb as an additive to gasoline. Elements that have often been associated with vehicular emissions include Cu, Zn, Pb, Br, Fe, Ca and Ba (Huang et al. 1994, Cadle et al. 1997, Kemp 2002, Morawska and Zhang 2002, Sternbeck et al., 2002). Emissions of many metallic elements from vehicular sources are mainly due to non exhaust emissions, examples from the wearing of tyres, brakes and other parts of vehicles (Sternbeck et al. 2002, Adachi and Tainosho 2004, Laschober et al. 2004, Lough et al. 2005). In addition to road traffic, emissions from the main and auxiliary engines of ships can be a significant source of particulate matter and associated elements such as V and Ni (Lyyrà ¤nen et al. 1999) at certain locations (Ohlstrà ¶m et al. 2000, Colvile et al. 2001, Isakson et al. 2001). 2.3.2 Stationary sources The most significant stationary combustion sources include energy production facilities such as municipal power plants, waste incineration, and residential combustion. Several industrial processes, such as iron and steel production, also involve combustion of fossil fuels or biomass for generating power and heat needed for the process. Most of these sources are considered point sources, although smaller and more widespread sources such as residential combustion could also be considered as an area source. Physical and chemical characteristics of the particles emitted from these source categories depends on the combustion process itself, and the type of fuel burnt (solid, liquid, or gas). Combustion processes and properties of particulate matter emitted from these sources have been comprehensively reviewed by Morawska and Zhang (2002). The major industrial processes include factories processing metals and chemicals, materials handling, construction and mining. Particulate matter from t hese sources are partly released as fugitive emissions, which are not collected and released in a controlled manner, but emitted from a variety of points and areas connected to a process (Seinfeld and Pandis 1998). Chemical and physical properties of fugitive emissions depend on the processes by which they are emitted. Since the bulk of most trace metals are nowadays emitted from industrial processes, their concentrations are spatially heterogeneous and subsequently, their measurement is quite sensitive in terms of location; however, the reported concentrations of trace metals in major cities demonstrate rather similar levels of trace metals (Harrison and Yin 2000). PM10 CHARACTERISTIC. PM is characterized by its physical, chemical and optical properties. The quality of air that we breathe in every second determine by the amount of particulate matter in it. These particulate matters measure by their particles size. Those with the particles size less than 10 micron (PM10) is used to monitor the air quality which in turn is related to the health problems of the workers or public at large (Alias et al., 2007). The most important characteristic of particulate matter (PM) is the particle size. This property has the greatest impact on the behavior of particulate matter in control equipment, the atmosphere, and the respiratory tract. Particles of importance in air pollution control span a broad size range from extremely small (0.01 micrometer) to more than 1,000 micrometers (US EPA, 2010). As a frame of reference, a human hair has a diameter of approximately 50 micrometers. The suspended particles vary in size, composition and origin. It is convenient to classify particles by their aerodynamic properties because, (a) these properties govern the transport and removal of particles from the air, (b) they also govern their deposition within the respiratory system and (c) they are associated with the chemical composition and sources of particles (WHO, 2003). 2.4.1 Physical Characteristic The physical attributes of airborne particulates include mass concentration and size distribution. the size is from a few nanometers (nm) to ten of micrometers ( µm) in diameter. Size is the single most important determinant of the properties of particles and it has implications on formation, physical and chemical properties, transformation, transport, and removal of particles from the atmosphere. Ambient levels of mass concentration are measured in micrograms per cubic meter (ÃŽÂ ¼g/m3), size attributes are usually measured in aerodynamic diameter. Particulate matter (PM) exceeding 2.5 microns (ÃŽÂ ¼m) in aerodynamic diameter is generally defined as coarse particles, while particles smaller than 2.5 microns (PM2.5) are called fine particles (World Bank Group, 1998). Particles of any substances that are less than 10 or 2.5 micrometres diameter. Particles in this size range make up a large proportion of dust that can be drawn deep into the lungs. Larger particles tend to be tr apped in the nose, mouth or throat. The concentration and other characteristics of suspended particulate matter are determined by the presence and activity of sources. Once formed, particles change their size and composition by condensation or evaporation, by coagulating with other particles or by chemical reactions (Seinfeld and Pandis 1998). Pohjola et al., (2000), found that meteorological factors such as wind speed and direction, temperature, amount of precipitation, and the height of the atmospheric boundary layer, are most important in governing the concentration variations of particulate matter. The highest PM concentrations are often reported during stable meteorological conditions such as inversion with low wind speeds (Pohjola et al. 2004). Also the physical and chemical processes affecting the particles are regulated to a great extent by meteorological factors. 2.4.2 Chemical Characteristic The chemical composition of the particulate matter is also important. The chemical composition of PM is highly variable due to pollution sources, chemical reactions in the atmosphere, long-range transport effects and meteorological conditions. Absorption and heterogeneous nucleation of vapor phase pollutants onto existing particles can create toxic particulate matter (US EPA, 2010). The chemical properties vary depending on sources of particles. It is important to note that particulates are not one particular chemical substance but a classification of particles by size rather then chemical properties.The acid component of particulate matter, and most of its mutagenic activity, are generally contained in fine particles, although some coarse acid droplets are also present in fog. Particles interact with various substances in the air to form organic or inorganic chemical compounds. The most common combinations of fine particles are those with sulphates (World Bank Group, 1998). The rela tive abundance of the major chemical components, termed as bulk chemical composition and also about trace element and strong acid contents was reviewed in the studies of Harrison and Jones (1995) and Harrison and Yin (2000). In addition to the bulk composition, Harrison and Yin (2000) also discussed trace element and strong acid contents. In the United States, sulphate ions account for about 40% of fine particulates and may also be present in concentrations exceeding 10 ÃŽÂ ¼g/m3 (US EPA, 1982). 2.5 PARTICULATE MATTER HEALTH EFFECT There are a very limited number of studies that relate air pollution to its health impact in Malaysia. The lack of data gathering for environmental epidemiological analysis makes it difficult to estimate the health impact of air pollution (Afroz et al., 2003). Whilst epidemiological studies have consistently demonstrated adverse effects of particulate matter exposure on human health, the mechanism of effect is currently unclear (Harrisonu Yin, 2000). The US Environmental Protection Agencys 1996 Air Quality Criteria for Particulate Matter reviewed the physiologic, toxicology, and epidemiologic studies related to the inhalation, deposition and health effects of PM exposures (US EPA, 1997). Some research has identified several plausible biological mechanisms for both the initial pulmonary injury and the consequent systemic effects (Neas, 1999). The respiratory system is the major route of entry for airborne particulates. The deposition of particulates in different parts of the human respiratory system depends on particle size, shape, density, and individual breathing patterns (mouth or nose breathing) (World Bank Group, 1998). In adults, PM exposure was associated with increased incidence of respiratory symptoms, transient decrements in pulmonary function levels, and the onset of chronic pulmonary disease in adults (Neas, 1999). Seaton (1995), has identified several plausible biological mechanisms for both the initial pulmonary injury and the consequent systemic effects following PM exposure and the initial pulmonary injury may be related to one or more properties of PM and its constituents including physical, chemical and biological characteristics. Several hypotheses have been proposed to explain the path physiology of PM induced health effects. The most obvious mechanism involves the reduction in pulmonary function in response to the pulmonary inflammation. In the hypoxia hypothesis, the susceptible population consists of individuals with severe respiratory disease whose pulmonary reserve capacity is already near the minimum compatible with life. Exposure to PM further lowers their pulmonary function le vels and results in emergency hospitalization and death (Neas, 1999) Children are especially susceptible to particulate matter pollution for several reasons, their respiratory systems are still developing, they breathe more air (and air pollution) per pound of body weight than adults and theyre more likely to be active outdoors. Older adults are also more likely to be affected by particulate matter pollution, possibly because they are more likely to have chronic heart or lung diseases than younger people. In addition, people who have heart or lung disease, such as congestive heart failure, angina, chronic obstructive pulmonary disease, emphysema or asthma, are likely to experience health effects earlier and at lower particulate matter pollution levels than healthy people (American Lung Association, 1996). The capacity of particulate matter to produce adverse health effects in humans depends on its deposition in the respiratory tract. Particle size, shape, and density affect deposition rates. The most important characteristics influencing the deposition of particles in the respiratory system are size and aerodynamic properties. In Malaysian Ambient Air Quality Guidelines (MAAQG), the level of PM10 concentrations are, 150 micrograms per cubic meter ( µg/m3) for 24 hour and 50 micrograms per cubic meter ( µg/m3) for the annual (Department of Environment, Malaysia, 2010). Some tiny pieces of particulate matter, PM10, are small enough to pass from our lungs to our bloodstream. PM can alter the bodys defense systems against foreign materials, damage lung tissues, aggravate existing respiratory and cardiovascular disease, and can lead to cancer. In some cases, PM exposure can even lead to premature death. Adverse health effects have been associated with exposures to PM over both short periods (such as a day) and longer periods (a year or more). The people who are most at risk are people with asthma, influenza, lung, heart, or cardiovascular disease, the elderly, and children. The human immune system developed in a time and environment where dust was made of large particles. Humans have developed a means of protecting themselves against these large particles. Particles larger than 10 microns generally get caught in the nose and throat, never making it as far as the lungs. Unfortunately, more recent human activity has created many particles that are much s maller, which can make it past our natural defenses, and can enter our systems (Fierro, 2000). The size of particles is directly linked to their potential for causing health problems. Most concerned about particles that are 10 micrometers in diameter or smaller because those are the particles that generally pass through the throat and nose and enter the lungs. Once inhaled, these particles can affect the heart and lungs and cause serious health effects. EPA groups particle pollution into two categories: Inhalable coarse particles, such as those found near roadways and dusty industries, are larger than 2.5 micrometers and smaller than 10 micrometers in diameter. Fine particles, such as those found in smoke and haze, are 2.5 micrometers in diameter and smaller. These particles can be directly emitted from sources such as forest fires, or they can form when gases emitted from power plants, industries and automobiles react in the air.

The hunger games book review

Catkins Overseen, along side fellow tribute PETA Mallard, is forced to fight for her life against stronger competitors from wealthier districts, some of whom have trained for this their whole lives. If Catkins Is going to win then Catkins will need to kill everyone In the games. The only question Is, are the odds ever In her favor? I personally admire the way that Catkins would willingly take her sister's place In the Ames, when there is a one in a million chance that she could win.The author has truly grasped the idea of what it's like to be in a situation like Catkins' – no father, a mother that's stuck in the past, and a 13-year-old sister that needs looking after. I was compelled after hearing about the games in the story. The whole prospect Just made me shatter with excitement. It's a very unusual and out-of-the ordinary plot for a book, but I think that its originality is what makes it Just that bit better than your tankard teen fiction.I think that the author's use of d escriptive techniques, Like personification, was extremely noticeable because of Its effectiveness on the story. Overall, I really enjoyed the book and highly recommend to those who love teen fiction or Just enjoy the adrenaline rush. Good Job Suzanne Collins, and I would definitely read it again.

Data Sources For Sociological Research

In conducting research, sociologists draw upon data from a variety of sources on different subjects: economy, finance, demography, health, education, crime, culture, environment, agriculture, etc. This data is gathered and made available by governments, social science scholars, and students from various disciplines. When the data are available electronically for analysis, they are typically called data sets. Many sociological research studies do not require the gathering of original data for analysis, especially since there are so many agencies and researchers gathering, publishing, or otherwise distributing data all the time. Sociologists may explore, analyze, and illuminate this data in new ways for different purposes. Below are a few of the many options for accessing data, depending on the topic you are studying. U.S. Census Bureau The United States Census Bureau is the government agency that is responsible for the United States Census and serves as a leading source of data about Americas people and economy. It also gathers other national and economic data, many of which are available online. The U.S. Census Bureau website includes data from the Economic Census, the American Community Survey, the 1990 Census, the 2000 Census, and current population estimates. Also available are interactive internet tools that include mapping tools and data at the national, state, county, and city level. The United States Bureau of Labor Statistics The Bureau Of Labor Statistics is a branch of the United States Department of Labor and is the government agency that is responsible for collecting data about employment, unemployment, pay and benefits, consumer spending, work productivity, workplace injuries, employment projections, international labor comparisons, and the National Longitudinal Survey of Youth. Data can be accessed online in a variety of formats. The National Center for Health Statistics The National Center For Health Statistics (NCHS) is a part of the Centers For Disease Control And Prevention (CDC) and is responsible for collecting data from birth and death records, medical records, interview surveys, and through direct physical exams and laboratory testing in order to provide important surveillance information that helps identify and address critical health problems in the United States. Data available on the website include Healthy People 2010 data, Injury data, National Death Index data, and the National Health and Nutrition Examination Survey. TheDataWeb Data Web: Data Ferrett is a network of online data libraries based on datasets provided by several U.S. government agencies including the Census Bureau, Bureau of Labor Statistics and the Center for Disease Control. Data topics include census data, economic data, health data, income, and unemployment data, population data, labor data, cancer data, crime and transportation data, family dynamics, and vital statistics data. Users need to download the DataFerret application (available from that site) in order to access and use the datasets. The National Survey of Families and Households National Survey Of Families And Households (NSFH) was designed to provide a broad range of information on family life to serve as a resource for research across disciplinary perspectives. A considerable amount of life-history information was collected, including the respondents family living arrangements in childhood, departures and returns to the parental home, and histories of marriage, cohabitation, education, fertility, and employment. The design permits the detailed description of past and current living arrangements and other characteristics and experiences, as well as the analysis of the consequences of earlier patterns on current states, marital and parenting relationships, kin contact, and economic and psychological well-being. Interviews were conducted in 1987-88, 1992-94, and 2001-2003. The National Longitudinal Study of Adolescent Health National Longitudinal Study of Adolescent Health (Add Health) is a longitudinal study of a nationally representative sample of adolescents in grades 7 to 12 in the United States during the 1994/1995 school year. The Add Health cohort has been followed into young adulthood with four in-home interviews, the most recent in 2008 when the sample was aged 24 to 32. Add Health combines longitudinal survey data on respondents social, economic, psychological and physical well-being with contextual data on the family, neighborhood, community, school, friendships, peer groups, and romantic relationships, providing unique opportunities to study how social environments and behaviors in adolescence are linked to health and achievement outcomes in young adulthood. The fourth wave of interviews expanded the collection of biological data in Add Health to understand the social, behavioral, and biological linkages in health trajectories as the Add Health cohort ages through adulthood.

Imagecreatetruecolor() PHP Function

The imagecreatetruecolor() function is used in PHP to create a new true color image using the GD Library. True color uses a 24-bit color depth when displaying an RGB image. Its two parameters are the width and height of the image you are creating. Sample Code Using Imagecreatetruecolor() Function This code generates a PNG image that is 130 pixels wide by 50 pixels high. The imagecreatetruecolor() function specifies a shape that is 130 pixels wide by 50 pixels high. The text color is set using RGB values. The text that will print on the shape is A Simple Text String, in size 1 (of 1-5) with an x ordinate of 5 and a y-ordinate of 5. Return Values When successful, this function returns an image identifier that represents a black image of the specified size. If not successful, it returns False. Considerations The GD library must be enabled for this function to work properly; otherwise, the return value is False. It can be downloaded free from the internet if you dont already have it installed. Imagecreatetruecolor() vs. Imagecreate() Function Although the imagecreate() function still works in PHP, the PHP manual recommends the use of the newer imagecreatetruecolor() function, which creates images with many more colorsmakes color transparency possibleallows advanced image processes
