The Power of Love in Moulin Rouge and To Dance With the White Dog Essay

The Power of Love in Moulin Rouge and To Dance With the White Dog      Ã‚  Ã‚   The power of love is exposed in the films Moulin Rouge and To Dance With the White Dog. In each movie, each individual must overcome obstacles within themselves in order to overcome the obstacles in their relationships. Although the love shared by each couple is different, both cases of love are real and run deeply. Satine and Sam Peek each handle their romantic relationships differently according to their situations.      Ã‚  Ã‚  Ã‚  Ã‚   The film, Moulin Rouge, takes place during the Bohemian period in which things such as truth, beauty, and love are key elements to live by.   Christian, A young writer falls deeply in love with Satine, the star dancer of the Moulin Rouge. They are forced to keep their love for each other a secret because a Duke wants Satine for himself and has become the funder for Christian's play. The Duke also promises Satine a chance to become a real actress. When Christian and Satine's relationship is found out by the Duke, their lives become endangered and though they were able to be together in the end, as was foretold throughout the movie, Satine dies, leaving Christian with a disillusioned view of love.      Ã‚  Ã‚  Ã‚  Ã‚   To Dance with the White Dog is a movie about love as well. An elderly widower, Sam Peek, is forced to deal with the sudden death of his wife after over fifty years of marriage. Throughout the movie his recollections of happy times spent with her are shown to the audience. Peek's children and his own illnesses cause him to suffer through the entire ordeal of dealing with losing his spouse and true love. One day, a very white dog appears at Peek's doorstep and from that point on that dog seems to ... ...for so long that having someone try to take her place was simply inconceivable. Maybe the backgrounds of Sam versus the background of Satine made the way they chose what they did in their lives so different. Possibly, the fact that To Dance With the White Dog was actually an account of a true event made a difference when comparing to the fictitious story, Moulin Rouge. Whatever the reason, each individual proved that true love can overcome all obstacles with the exception of death. And even that will not limit the longevity of love. Sam Peek and Satine each showed their undying love for their mate in different ways but managed to get the message across to them just the same.    Works Cited    Moulin Rouge. Dir. Baz Luhmann.

CEO of Ventura Electronics Essay

Financial statement analysis is done by every successful corporation, as your team at Ventura Electronics very well knows. â€Å"Comparisons within a company are often useful to detect changes in financial relationships and significant trends† (Kimmel, Weygandt, and Keiso p. 653). Financial statement analysis is done by horizontal analysis, vertical analysis, and ratio analysis. â€Å"Horizontal analysis, also known as trend analysis, is a technique for evaluating a series of financial statement data over a period of time (Kimmel, Weygandt, and Keiso p. 54). If Ventura Electronics is interested in determining any increase or decrease in, for example, net sales (as an amount or percentage) than horizontal analysis are appropriate. Vertical analysis analyzes more specific data on the financial statement. â€Å"Vertical analysis, also called common-size analysis, is a technique for evaluating financial statement data that expresses each item in a financial statement as a percen t of a base amount†(Kimmel, Weygandt, and Keiso p. 656). Ventura Electronics can not only analyze the relative size of each category on the financial statement, but can also see the percentage change in the individual asset, liability, and stockholders’ equity. Ventura Electronic can also use this analysis when comparing its financial statements to the competition. The last tool commonly used for financial statement analysis is ratio analysis. These ratios are useful in evaluating the financial health and performance of a company. In ratio analysis we use three different ratios; liquidity ratios, solvency ratios, and profitability ratios. Liquidity ratios are important because it evaluates the short-term ability of a business to pay their obligations as well as meet their unexpected cash flow needs. When Ventura Electronics wants to measure the ability of the company to survive over a long period of time then solvency ratios are appropriate. Profitability ratios evaluate the income of the business or their operating success over a given period of time. Ventura Electronics would find this ratio very important in analyzing the company’s income and to evaluate the ability for the business to obtain debt and equity financing, its liquidity position, and its ability to grow. As CEO, this ratio would be useful when determining the managements operating effectiveness. It is very important for Ventura Electronics to provide â€Å"full and transparent information that will not confuse or mislead users of the financial statements† (Kimmel, Weygandt, and Keiso p. 61) this is called quality of earnings. When Ventura Electronics performs a financial statement analysis to evaluate the financial performance of the company using the methods above, it is important to maintain a high quality of earnings. Factors that affect quality of earnings are; alternative accounting methods, pro forma income, improper recognition, and price-earnings ratio. Though financial statement analysis is important for Ventura Electronics, it also has its limitations  The limitation of financial statement analysis occurs with ratio analysis. Though this analysis is very useful to the company in analyzing internal factors, Ventura Electronics cannot compare ratios to their competitors accurately. Differences in accounting methods limit ratio analysis in comparing companies. As the CEO you understand the importance of knowing where the company stands as compared to its competitors. Ratio analysis also limits Ventura Electronics to analyze the definite future of the organization. They do not account for industry trends, technological changes, changes in consumer tastes, changes in broad economic factors, and changes within the firm itself. Though ratio analysis has its limitations; horizontal and vertical analysis makes up for these limitations. So as you can see, if the methods for financial statement analysis listed above are used, Ventura Electronics can receive a great knowledge and insight into how successful the company is and could be and make proper decisions based off these evaluations.

Influence of Western European Economy on Migration Since 1945 Essay

After the end of the second world war, many European countries suffered from the effects of the war and the future of the continent was in doubt. Most countries had a hard time rebuilding and recuperating their economies from the aftershocks of the war. The western part of Europe, after a torrid time of economic and political hardship, began to recover and rebuild their countries. In the years that came after the war, the countries in the western region had to enact cooperative measures with each other as opposed to competing with each other to ensure that they survived the torrid period together. This period was marked by complex processes with the rolling out economic programs that would reduce trade barriers among the countries and this kick started a period of significant economic development in the region. The migration history of Europe represents an unplanned development and unintended occurrence. It represented a combination of labor migrants, colonial migrants and asylum see kers (Schönwälder, 2003). This essay will establish the link between successful economic periods in western Europe and the levels of migration into these areas. The postwar migration can be categorized into two phases; a regime which involved colonial migration and that which involved the migration of guest workers. Those migrated came to look for work opportunities which were created by the ten recovering and booming economies in Western Europe. In the 1970’s, there was an interaction of economic deficiencies with colonial migration before the war. This also interacted with the existing citizenship regulations in countries such as France, Belgium, UK and the Netherlands while countries such as Austria , Denmark, Germany Sweden and Switzerland had implemented guest-workers policies that were a major attraction for foreign migrants. Germany enacted a currency reform in 1948 which instigated the recovery of its economy. In mid 1950’s, the country along with the others in the western region of Europe experienced high labor demand levels that could not be satisfied locally. A unanimous pattern in Western Europe at that time involve d sourcing of labor from the eastern parts of Europe as they believed that migrants from those parts could be integrated easily into their systems. This expanded into the northern countries in Africa and countries near the periphery of middle east such as Turkey. The countries arranged guest-worker schemes among themselves and other interested countries out of their region. Trade unions especially in Germany saw the guest-worker programs as a threat to existing wage rates as they feared that they would experience a downward spiral at the end. Governments in Western Europe particularly Germany’s incorporated measures that ensured that the guest workers enjoyed the equal work conditions as their European counterparts. The basic principle behind the scheme of guest-workers was that that the foreign workers would remain in the countries as long as they held their jobs and would leave back to their native countries once the economy started to perform badly. In Germany for example, many guests-workers left the country during the 1968 economic recession with the guarantee that they could return when the economy recovered and the labor demand went up again. In the early 1970’s, the huge numbers of migrant workers in the European market were causing an economic slowdown and most of the countries responded to this by stopping the migration programs in 1973. This, however did not result into the intended result of migrants moving back to their countries. Many guests-workers remained in the countries where they received help from NGOs and charitable organizations in addition to favorable court judgements which permitted their stay. This case was most prevalent in Germany. Countries such as France, Sweden, Austria, Belgium, Switzerland and Holland implemented varying forms of the guest-workers policies which sharply decreased the extent of migration related to labor from 1973 onwards. In the other regime of labor migration touching on colonial background, bilateral and multilateral agreements in regard to guest-workers became the sole supply of migrant labor. UK, Netherlands, France and Belgium had the capability of drawing huge numbers of unskilled laborers. Policymakers were thought to have tapped at the opportunity colonial labor offered to satisfy the boom experienced after the war but this was not the case. The inability to secure domestic workers meant that the policymakers had to rely on colonial migrants to feed the labor demand. This was mostly practiced in France and UK with limited implementation in Belgium and the Netherlands (Schönwälder, 2003). In the postwar period, UK put into trial its version of the migrant worker scheme by sourcing workers from the Eastern part of Europe. However, the local economy became sluggish and this reduced the pull factor that UK had on migrant workers. Countries such as Germany, France, Austria and Switzerland were more appealing and attractive to migrant workers from eastern Europe countries. The UK economy was not on the same level with the rest of western Europe but its situation with guest-workers were enhanced by its citizenship program which integrated over half a billion colonial subjects into the country’s fold. In 1948, UK had in place legislation that confirmed all of its former colonial subjects as the country’s citizens with rights to enter and enjoy all social, economic and political rights within the country. The resulting occurrence was the inflow of migrants of Indian and Pakistan origin in the country. The economy of the country enjoyed a full employment rate at the time and there were labor shortages which the migrants helped to correct. By 1962, UK had over half a million non-white colonial migrants and this marked the start of restrictive measures that regulated the inflow of colonial migrants. The figure of non-white colonial migrants had risen to over a million by 1972, a period which saw UK cut on the privileges associated with UK nationality status at the time (Strayer, 2009). France on the other hand concentrated on migrants from northern Africa particularly from Algeria though not a former French colony. The supply of the labor migrants was hampered by completion from Germany and Switzerland which were experiencing increased economic growth. This shortened the supply of labor in France and the interest of the European nations in colonial labor resulted to an increased migration of Algerians into the country as they had the right to enter France, a case similar to that of UK. French companies sourcing for cheap labor looked to Algeria, Tunisia and Morocco as credible sources of such labor. The system was tighter in Austria, Germany and Switzerland but the French took the opportunity to directly hire colonial migrants into their companies and confirm their nationality status afterwards through the National Immigration Office (Foley, 1998). In recent decades from the 1980’s, the largest percentage of migrants into Europe have come from West Africa. This has been accentuated by extreme poverty levels, high rates of unemployment and political instability in some of the nations. This has been enhanced by the perception held by many people that Africa is a continent plagued by miseries of all kinds. Despite these challenges afflicting people in Africa, the promise of a better life and economic conditions in the dominant Western Europe countries offers a unique attraction to African migrants into the economically developed countries. The European economy is a major contributor to the success of the global economy and presents numerous lucrative and medium scale job opportunities for skilled, semi-skilled and unskilled laborers from all walks of life. The prevailing excellent economic conditions act as the main pull factors for migration into the more popular countries in Europe such as Germany, France and UK. These co untries offer a chance for many migrants who are driven by the sheer aspiration to live in a western country. After many African countries gained independence, the education systems were hugely improved and this resulted into the outlet of highly learned and qualified personnel . The demand for expatriates and skilled labor in the Western European economy presented a great chance for the ;learned people to move abroad and try their luck with corporate and technological jobs. Most colonial powers had projects that flew talented students in their countries to present better academic opportunities for Africans. In the current era, a significant number of migrants in the Western part of Europe are students who come to achieve advanced educational dreams. The European countries are well economically developed which translates into quality education structures which are among the best in the world. Many students of African, Indian and Asian descent migrate to these countries to tap into t he great educational opportunities that are present in these countries (Schönwälder, 2003). Migration patterns are created through network functionality. Which leads to the rise of migration systems that act as links to origin and destination countries through an established exchange of products, people, information and capital remittances. The systems may be legal or informal but all contribute to the continous cycle of family and labor migration . Currently,many countries in Western Europe pay more attention to migration of skilled laborers who are viewed as capable of bettering their economic growth. The UK and Germany have taken significant steps towards this priority by issuing work permits to the highly-skilled labor migrants. This attracts many professionals who believe they have a great chance of succeeding in those countries. In 2000, Germany introduced a ‘green card’ program aimed at attracting over 20000 highly qualified workers. This was in pursuit of further economic progress, a factor that acted well in raising the migration levels in the country and therefore into Europe. In a period spanning from 1999 to 2004, France has seen the number of foreign migrant rise from 376000 to more than 570000 which signifies a rise of 35000 migrants annually. These migrants were mostly of African descent who came to France for educational. Job and resettlement purposes. In Britain and the Netherlands, the levels are not too far apart from those in France with an annual inflow of more than 10000 migrants being reported. These migrants come into these countries either illegally or legally. The legal form of migration differs with the driving motive of the migrants (Foley,1998). This brings in the third aspect migration into Western Europe fuelled by the economic success enjoyed in this region. Many countries in Western Europe enjoy unperturbed peace and economic stability. All of them are members of the United Nations and are bound by the regulations and principles that are core to the operations of the United nations. In recent years dating from the 1970’s into the new millennium some African countries have suffered from political instabilities which have resulted into civil unrests in those countries. The civil unrest acted as the push factor which caused many migrants to leave their war stricken countries. However, the choice of their destination country was mainly influenced by , the economic stability of that country. Many western European countries presented this option and represent viable choices where the migrants can be granted asylum and thrive under better humanitarian conditions as opposed to neighboring countries. The migrants go against all odds to reach the European mainland with the hope that once they are there, they will find ways of integrating i nto the local population and tap into the available opportunities of work and settlement. In the 1980’s, asylum applications had reached 320000 and more than doubled from 1992 in Germany. In Britain the numbers hit the 100000 mark. Most of these migrants are offered refugee status but their main aim of coming to these countries is to find a better a life away from their native countries. This notion is enhanced by the high economic performance levels identified with the European economy(Strayer, 2009). In the European region, specifically the western part offers the second largest intra-regional migration of workforce behind America. Most of the migrants in this region have been attracted to this place by the prospect of successful lives in countries and regions experiencing economic booms. However, the uncontrolled number of illegal migrants poses a challenge to them and the same economy that attracted them to these countries. Most of these migrants are mostly concentrated in low-skill tertiary sectors of the various industries present in the region. With the recent economic crisis in the world and in the European region, most of the migrants were faced with various vulnerabilities associated with economic pressure as they depended on unsustainable resources and their status as migrants only made matters worse for them. In light of the economic problems that afflicted the region in 2008,. The countries in the region in conjunction the whole EU body started to enact immigration pol icies that would control the levels of migration during the hard economic conditions. These policies were proposed and enacted to shield the labor sector from increased worsening conditions and to protect the existing wage rates which had a significant effect of the economic downturn at the time (Kaelble, 2011). In conclusion, it is clearly evident that many push and pull factors that have influenced migration into Western Europe. However, the economic success that the region has enjoyed in the years after the second world war in the current era of economic recessions and recoveries acted as a major influence in determining which part the migrants moved to. The economic conditions in this region provided numerous opportunities for the migrants to progress their lives and mould a successful future. With the demand for labor souring in the region at one time and the advent of excessive inflow of migrants through various economic periods shaped by both success and downturns, the main pull for migrants to the western part of Europe was the economic development that Europe was identified with.

Star Clusters

Star Clusters Star clusters are just what the name says they are: groupings of stars that can include anywhere from a few dozen to hundreds of thousands or even millions of stars! There are two general types of clusters: open and globular.   Open Clusters The open clusters, such as the Beehive in the constellation of Cancer and the Pleiades that grace the sky in Taurus, are groups born in the same area of space but are only  loosely  gravitationally bound together. Eventually, as they travel through the galaxy, these stars  wander apart from each other. Open clusters usually have up to  a thousand or so members, and their  stars are  not more than 10 billion years old. These clusters  are much more likely to be found in the disks of spiral and in irregular galaxies, which contain more star-forming material than older, more evolved elliptical galaxies. The Sun was born in an open cluster that formed about 4.5 billion years ago. As it moved through our rotating galaxy, it left its siblings behind long ago. Globular Clusters Globular clusters are the mega-clusters of the cosmos. They orbit the central core of our galaxy, and their thousands and thousands of  stars are held together by a strong mutual gravity  that creates a sphere or globe of stars. Generally speaking, stars in globulars are among the oldest  in the universe, and they formed early in a galaxy’s history. For example, there are stars in globulars orbiting our galaxys core that were born when the universe (and our galaxy) was quite young.   Why Are Clusters Important to Study? Most stars are born in these big batches within large stellar nurseries.Observing and measuring stars in clusters gives astronomers great insight into the environments in which they formed. Stars born recently often are more metal-rich than those that formed much earlier in history.  Metal-rich means that they contain more elements heavier than hydrogen and helium, such as carbon and oxygen.  If their birth clouds were rich in certain kinds of elements, then those stars will contain higher amounts of those materials. If the cloud was metal-poor (that is, if had a lot of hydrogen and helium, but very few other elements), then the stars it formed will be metal-poor. Stars in some globular clusters in the Milky Way are quite metal-poor, which indicates they formed when the universe was very young and there hadnt been time to form enough of the heavier elements.   When you look at a star cluster, youre seeing the the basic building blocks of galaxies. Open clusters provide the stellar population of a galaxys disk while the globulars hark back to a time when their galaxies were forming through collisions and interactions. Both stellar populations are clues to the ongoing evolution of their galaxies and of the universe. For stargazers, clusters can be fantastic observation targets. A few well-known open clusters are naked-eye objects.  The Hyades is another choice target, also in Taurus. Other targets include the Double Cluster (an pair of open clusters in Perseus), the Southern Pleiades (near Crux in the Southern Hemisphere), the globular cluster 47 Tucanae (a  fabulous sight in Southern Hemisphere constellation Tucana), and the globular cluster M13 in Hercules (easy to spot with binoculars or a small telescope).

Chemistry Vocabulary - Definitions of Chemistry Terms This is a list of important chemistry vocabulary terms and their definitions. A more comprehensive list of chemistry terms can be found in my alphabetical chemistry glossary. You can use this vocabulary list to look up terms or you can make flashcards from the definitions to help learn them. absolute zero - Absolute zero is 0K. It is the lowest possible temperature. Theoretically, at absolute zero, atoms stop moving. accuracy - Accuracy is a measure of how close a measured value is to its true value. For example, if an object is exactly a meter long and you measure it as 1.1 meters long, that is more accurate than if you measured it at 1.5 meters long. acid - There are several ways to define an acid, but they include any chemical that gives off protons or H in water. Acids have a pH less than 7. They turn the pH indicator phenolphthalein colorless and turn litmus paper red. acid anhydride - An acid anhydride is an oxide that forms an acid when it is reacted with water. For example, when SO3- is added to water, it becomes sulfuric acid, H2SO4. actual yield - The actual yield is the amount of product you actually obtain from a chemical reaction, as in the amount you can measure or weigh as opposed to a calculated value. addition reaction - An addition reaction is a chemical reaction in which atoms add to a carbon-carbon multiple bond. alcohol - An alcohol is any organic molecule that has an -OH group. aldehyde - An aldehyde is any organic molecule that has a -COH group. alkali metal s of alkali metals include lithium, sodium, and potassium. alkaline earth metal s of alkaline earth metals are magnesium and calcium. alkane - An alkane is an organic molecule that only contains single carbon-carbon bonds. alkene - An alkene is an organic molecule that contains at least one CC or carbon-carbon double bond. alkyne - An alkyne is an organic molecule that contains at least one carbon-carbon triple bond. allotrope - Allotropes are different forms of a phase of an element. For example, diamond and graphite are allotropes of carbon. alpha particle - An alpha particle is another name for a helium nucleus, which contains two protons and two neutrons. Its called an alpha particle in reference to radioactive (alpha) decay. amine - An amine is an organic molecule in which one or more of the hydrogen atoms in ammonia have been replaced by an organic group. An example of an amine is methylamine. base - A base is a compound that produces OH- ions or electrons in water or that accepts protons. An example of a common base is sodium hydroxide, NaOH. beta particle - A beta particle is an electron, although the term is used when the electron is emitted in radioactive decay. binary compound - A binary compound is one made up of two elements. binding energy - Binding energy is the energy that holds protons and neutrons together in the atomic nucleus. bond energy - Bond energy is the amount of energy required to break one mole of chemical bonds. bond length - Bond length is the average distance between the nuclei of two atoms that share a bond. buffer - A liquid that resists change in pH when an acid or base is added. A buffer consists of a weak acid and its conjugate base. An example of a buffer is acetic acid and sodium acetate. calorimetry - Calorimetry is the study of heat flow. Calorimetry may be used to find the heat of reaction of two compounds or the heat of combustion of a compound, for example. carboxylic acid - A carboxylic acid is an organic molecule containing a -COOH group.

Enzymes are proteins that act as catalysts for biochemical reactions. cathode - A cathode is the electrode which gains electrons or is reduced. In other words, it is where reduction occurs in an electrochemical cell. chemical equation - A chemical equation is a description of a chemical reaction, including what reacts, what is produced, and which direction(s) the reaction proceeds. chemical property - A chemical property is a property that can only be observed when a chemical change occurs. Flammability is an example of a chemical property, since you cant measure how flammable a substance is without igniting it (making/breaking chemical bonds). covalent bond - A covalent bond is a chemical bond formed when two atoms share two electrons. critical mass - Critical mass is the minimum quantity of radioactive material needed to cause a nuclear chain reaction. critical point - The critical point is the endpoint of the liquid-vapor line in a phase diagram, past which a supercritical liquid forms. At the critical point, the liquid and vapor phases become indistinguishable from one another. crystal - A crystal is an ordered, repeating three-dimensional pattern of ions, atoms, or molecules. Most crystals are ionic solids, although other forms of crystals exist. delocalization - Delocalization is when electrons become free to move all over a molecule, such as when double bonds occur on adjacent atoms in a molecule. denature - There are two common meanings for this in chemistry. First, it can refer to any process used to make ethanol unfit for consumption (denatured alcohol). Second, denaturing can mean breaking down the three-dimensional structure of a molecule, such as a protein is denatured when exposed to heat. diffusion - Diffusion is the movement of particles from an area of higher concentration to one of lower concentration. dilution - Dilution is when a  solvent is added to a solution, making it less concentrated. dissociation - Dissociation is when a chemical reaction breaks a compound into two or more parts. For example, NaCl dissociates into Na and Cl- in water. double displacement reaction - A double displacement or double replacement reaction is when cations of two compounds switch places. effusion - Effusion is when a gas moves through an opening into a low-pressure container (e.g., is drawn by a vacuum). Effusion occurs more quickly than diffusion because additional molecules arent in the way. electrolysis - Electrolysis is using electricity to break the bonds in a compound to break it apart. electrolyte - An electrolyte is an ionic compound that dissolves in water to produce ions, which can conduct electricity. Strong electrolytes completely dissociate in water, while weak electrolytes only partially dissociate or break apart in water. enantiomers - Enantiomers are molecules that are non superimposable mirror images of each other. endothermic - Endothermic describes a process that absorbs heat. Endothermic reactions feel cold. endpoint - The endpoint is when a titration is stopped, typically because an indicator has changed color. The endpoint need not be the same as the equivalence point of a titration. energy level - An energy level is a possible value of energy that an electron can have in an atom. enthalpy - Enthalpy is a measure of the amount of energy in a system. entropy - Entropy is a measure of the disorder or randomness in a system. enzyme - An enzyme is a protein that acts as a catalyst in a biochemical reaction. equilibrium - Equilibrium occurs in reversible reactions when the forward rate of the reaction is the same as the reverse rate of the reaction. equivalence point - The equivalence point is when the solution in a titration is completely neutralized. It is not the same as the endpoint of a titration because the indicator may not change colors precisely when the solution is neutral. ester - An ester is an organic molecule with a R-CO-OR function group. excess reagent - Excess reagent is what you get when there is leftover reagent in a chemical reaction. excited state - An excited state is a higher energy state for an electron of an atom, ion, or molecule, compared with the energy of its ground state. exothermic - Exothermic describes a process that gives off heat. family - A family is a group of elements sharing similar properties. It is not necessarily the same thing as an element group. For example, the chalcogens or oxygen family consists of some different elements from the nonmetal group. Kelvin - Kelvin is a unit of temperature. A Kelvin is equal in size to a degree Celsius, although Kelvin starts from absolute zero. Add 273.15 to a Celsius temperature to get the Kelvin value. Kelvin is not reported with a  ° symbol. For example, you would simply write 300K not 300 °K. ketone - A ketone is a molecule that contains a R-CO-R functional group. An example of a common ketone is acetone (dimethyl ketone). kinetic energy - Kinetic energy is energy of motion. The more an object moves, the more kinetic energy it has. lanthanide contraction - The lanthanide contraction refers to the trend in which lanthanide atoms become smaller as you move left to right across the periodic table, even though they increase in atomic number. lattice energy - Lattice energy is the amount of energy released when one mole of a crystal forms from its gaseous ions. law of conservation of energy - The law of conservation of energy states the energy of the universe may change form, but its amount remains unchanged. ligand s of common ligands include water, carbon monoxide, and ammonia. mass - Mass is the amount of matter in a substance.

For example, the oxidation number of an oxygen atom is -2. period - A period is a row (left to right) of the periodic table. precision - Precision is how repeatable a measurement is. More precise measurements are reported with more significant figures. pressure - Pressure is force per area. product - A product is something made as a result of a chemical reaction. quantum theory - Quantum theory is the description of energy levels and the predictions about the behavior of atoms at specific energy levels. radioactivity - Radioactivity occurs when the atomic nucleus is unstable and breaks apart, releasing energy or radiation. Raoults Law - Raoults Law states that the vapor pressure of a solution is directly proportional to the mole fraction of solvent. rate determining step - The rate determining step is the slowest step in any chemical reaction. rate law - A rate law is a mathematical expression relating the speed of a chemical reaction as a function of concentration. redox reaction - A redox reaction is a chemical reaction that involves oxidation and reduction. resonance structure - Resonance structures are the set of Lewis structures that can be drawn for a molecule when it has delocalized electrons. reversible reaction - A reversible reaction is a chemical reaction which can go both ways: reactants make products and products make reactants. RMS velocity - The RMS or root mean square velocity is the square root of the average of the squares of individual velocities of gas particles, which is a way of describing the average speed of gas particles. salt - An ionic compound formed from reacting an acid and a base. solute - The solute is the substance that gets dissolved in a solvent. Usually, it refers to a solid that is dissolved in a liquid. If you are mixing two liquids, the solute is the one that is present in a smaller amount. solvent - This is the liquid that dissolves a solute in solution. Technically, you can dissolve gases into liquids or into other gases, too. When making a solution where both substances are in the same phase (e.g., liquid-liquid), the solvent is the largest component of the solution. STP - STP means standard temperature and pressure, which is 273K and 1 atmosphere. strong acid - A strong acid is an acid that completely dissociates in water. An example of a strong acid is hydrochloric acid, HCl, which dissociates into H and Cl- in water. strong nuclear force - The strong nuclear force is the force that holds the protons and neutrons in an atomic nucleus together. sublimation - Sublimation is when a solid changes directly into a gas. At atmospheric pressure, dry ice or solid carbon dioxide goes directly into carbon dioxide vapor, never becoming liquid carbon dioxide. synthesis - Synthesis is making a larger molecule from two or more atoms or smaller molecules. system - A system includes everything you are evaluating in a situation. temperature - Temperature is a measure of the average kinetic energy of particles. theoretical yield - Theoretical yield is the amount of product which would result if a chemical reaction proceeded perfectly, to completion, with no loss. thermodynamics - Thermodynamics is the study of energy. titration - Titration is a procedure in which the concentration of an acid or base is determined by measuring how much base or acid is required to neutralize it. triple point - The triple point is the temperature and pressure at which the solid, liquid, and vapor phases of a substance exist in equilibrium. unit cell - A unit cell is the simplest repeating structure of a crystal. unsaturated - There are two common meanings for unsaturated in chemistry. The first refers to a chemical solution that does not contain all of the solute that can be dissolved in it. Unsaturated also refers to an organic compound which contains one or more double or triple carbon-carbon bonds. unshared electron pair - An unshared electron pair or lone pair refers to two electrons that arent participating in chemical bonding. valence electron - The valence electrons are the atoms outermost electrons. volatile - Volatile refers to a substance that has a high vapor pressure. VSEPR - VSEPR stands for Valence Shell Electron Pair Repulsion. This is a theory used that predicts molecular shapes based on the assumption that electrons stay as far as possible from each other.

Fru gene is created out of spliced transcripts from four distinct promoters. Lee et. al. (2000) added that, FruM is manifested in w2% of neurons in the Central Nervous System of male. These neurons are arranged into 21 distinct clusters in several regions of the ventral ganglia and brain, including some of the areas or regions implicated in male sexual behavior. Similarly, the complex behaviors of insects are related to the organization of their nervous system; the neural pathways from sensory to motor circuits must be properly explored to understand their behaviors; and focused also in the body electrophysiological nature (Lee, 2000). The male P1 transcripts according to Demir & Dickson (2005), encode male-specific proteins (FruM) which are both important and sufficient for male sexual behavior. The aforemention ed literatures and those which were cited under the discussions and implications are quite reliable which supported the study. This research postulated that there are several fruGAL4-expressing neurons which are interconnected in a circuit and are involved in male sexual behavior. This circuit can be named accordingly: Sensory, central, and motor components. Basically, the study is directed towards exploration o... It also intended to assess whether "fruGAL4 reproduces the endogenous pattern of fru P1 transcripts". To achieve these, the proponents conducted gene targeting for labeling and manipulation of neurons, whereby they particularly add the GAL4 exposed reading frame to the fru P1 transcripts. In other words, various GAL4-responsive UAS transgenes were utilized. In fact, they also have stained brains and anterior nerve cords from fruGAL4, UAS-nlacZ heterozygous males with anti- "-galactosidase (anti-"-gal) and anti- FruM antibodies. The membrane tethered GFP reporter (UAS-mCD8-GFP) was utilized to closely observe the actual projection patterns of fruGAL4 neurons among the males and to find out for the potential differences in these projections among the females. Aside from this, to find out whether fru GAL4 ORNs work in male courtship behavior, an FLP-in strategy analogous to that one being used for their anatomical characterization was employed.Single-pair courtship assays were also prep ared, in which males of these genotypes were joined to the wild-type virgin females. These assays were carried out in the dark in order to get rid of any visual cues that might affect or influence courtship, thereby increasing the male's reliance on chemosensory cues. Behavioral Assays, Immunohistochemistry and FLP-in-Silencing Constructs are all very powerful methods and fitted for the study. If we take a closer look on the assumptions and methods presented, the authors considered the classical as well as updated theories and principles for its variables. Thus, a very strong theoretical basis in the pursuit of the approaches or methods used has been established. Approaches utilized are congruent to the expected outcomes.

Rousseau's Influence on the Critical Theory of Karl Marx Essay

Rousseau's Influence on the Critical Theory of Karl Marx - Essay Example This led to the movement of some sociologists. Theory of Karl Marx is an important milestone in this fightback for the poor and lesser privileges sections of the society. The critical theory of Karl Marx was another fine example in the series of thought provoking ideas of how the sociologists desired the world to be. It was in June 1844 that the critical theory emerged with the Economical and Philosophical Manuscripts of Karl Marx. He continued to work towards symbolizing the class struggle with the Hegelian philosophy as a guiding principle and came out with the first volume of his critical analysis of capitalism, Das Capital in 1867, which was a treatise of the economy and politics prevailing in the the 20th century1. Born on 5th May 1818 in Trier, Prussia (now Germany) Karl Marx was a highly influential thinker and revolutionary who started following the philosophical tradition of G. W. F. Hegel, but turned develop his system of thought mainly on the political aspects of economy (Jones, 2001). While working on the critical theory, Karl Marx took inspiration from a number of contemporary and earlier social thinkers. Jean Jacques Rousseau, a Swiss born political theorist was one such writer which finds an influence in the propounding of the critical theory. ... In the critical theory it was suggested that the class conflict would end up destroying the capitalism and lead to socialist society in which the resources would be equitably distributed instead of benefiting a selected few (Griffiths, 2005). Rousseau was a leading writer who is often considered as one of the earliest torchbearer of the modern socialism and communism. This very thought is echoed in the works of Karl Marx as well. Rousseau too criticized the tendency amongst the individuals towards amassing wealth at the cost of further impoverishing a large section of our society. He postulated man in a 'state of nature', in which he depicted how the man is divested of his social and cultural aspects (Zeitlin, 2000). In his 'Discourse on the Origin of Inequality' Rousseau argued that human beings by nature do not indulge in irrational behavior, but the social inequality becomes the root cause of injustice and moral corruption (Adams and Dyson, 2003). In fact, it has been argued by ma ny sociologists that failings of social structure result in alienation. The failings can be pinpointed as weaknesses in the moral fiber of the social organs or as a deliberate manipulation of social relations. Thinkers like Rousseau and Marx suggested adopting ways and means so that the effects of alienation can be minimized on the masses and the social fabric can be reconstructed for creating a better world. Rousseau suggested that in order to harmonize the social equality concept, the natural man need to be discovered. He stated that conducting experiments for such discoveries might prove to be difficult and therefore he suggested some alternatives to approach the problem. These alternatives included (Zeitlin,
