Some other types are known by the acronyms ESFJ, ENFP, INFP, ISFJ, and INTP. People with ENFJ personality type are often described as warm, outgoing, loyal, and sensitive. Illustration by JR Bee, Verywell Of all the personality types, the ENFJ is often perceived as being the strongest people person. They are capable of forging friendships of all personality types, even with more introverted or reticent individuals. Because of their ability to sense what others feel and affect how people behave, they do have the ability to influence and even manipulate others. This is balanced by their strong value system and desire to help other people be the best that they can be. ENFJ is the opposite of the ISTP personality type. Psychologist David Keirsey suggests that approximately two to five percent of all people have an ENFJ personality. Key ENFJ Characteristics ENFJs are strong extraverts; then sincerely enjoy spending time with other people. They have great people skills and are often described as warm, affectionate and supportive. Not only are people with this personality type great at encouraging other people, they also derive personal satisfaction from helping others.ENFJs are often so interested in devoting their time to others that they can neglect their own needs. They also have a tendency to be too hard on themselves, blaming themselves for when things go wrong and not giving themselves enough credit when things go right. Because of this, it is important that people with this personality type regularly set aside some time to attend to their own needs.They are also good at bringing consensus among diverse people. For this reason, they can be outstanding leaders and bring an enthusiasm to a group that can be motivating and inspirational.One common myth about ENFJs is that they are always sociable. While they love people, they do need time alone in order to assimilate and organize their thoughts. Strengths Outgoing and warm-hearted Empathetic Wide social circle Encouraging Organized Weaknesses Approval-seeking Overly sensitive Indecisive Self-sacrificing Cognitive Functions Each MBTI personality type can be identified by a hierarchical stack of cognitive functions that represent how each person interacts with the world. These functions focus on how people take in information about the world and how they then use this information to make decisions. Dominant: Extraverted Feeling ENFJs express this cognitive function through their engaging social behavior and harmonious social relationships. They are in tune with other peoples feelings, often to the point that they ignore their own needs in order to please others. ENFJs place a stronger emphasis on personal, subject considerations rather than objective criteria when making decisions. How a decision will impact others is often a primary concern. Auxiliary: Introverted Intuition ENFJs like to think about the future rather than the present. They may often become so focused on the larger goal that they lose sight of the immediate details. As ENFJs take in information about the world, their introverted intuition processes this data in order to create impressions, ideas, and thoughts. This allows them to spot patterns and make sense of complex or abstract data. Tertiary: Extraverted Sensing In an ENFJs personality, extraverted sensing causes them to take in the present moment, gathering concrete details and sensory information from the environment. Because of this, they will often seek out novel or interesting experiences and sensations. People with this personality type tend to be very aware of their present environment. This can lead to a great appreciation of aesthetics and a desire to create a pleasing space. Inferior: Introverted Thinking ENFJs are organized and enjoy structure and careful planning. Sticking to a predictable schedule helps ENFJs feel in control of the world around them. Because this is an inferior function, ENFPs may not have a great deal of confidence in their own ability to be logical and organized. Developing this function can help people with this personality type feel more balanced and in control of their decision-making process. Neglecting this aspect of personality can lead to relying solely on personal values when making decisions and neglecting the need for logic. ENFJs You Might Know Abraham Maslow, psychologistPeyton Manning, football playerBarack Obama, U.S. presidentBono, musicianElizabeth Bennet, character in Pride and Prejudice Personal Relationships ENFJs value other people highly and are warm, nurturing, and supportive in personal relationships. At times they can become very wrapped up in other peoples problems. They are altruistic and interested in helping others, which can sometimes come off as a bit overbearing. Despite this, they are usually very well liked and people appreciate their genuine concern and care. As parents, ENFJs are nurturing and warm, although they can sometimes be accused of being so-called helicopter parents. They are directly involved in their childrens lives, although they can sometimes be quite strict and even rigid at times. ENFJs need to remember to give their children room to explore and express their individuality, particularly as children age into adolescence. ENFJs have an outgoing personality and enjoy spending time with other people. Being in social settings helps them feel energized. In friendships and other relationships, people typically describe ENFJs as supportive and fun to be around. They are particularly good at relating to others and are known to help bring out the best in the people with whom they spend their time. Career Paths ENFJs often do best in careers where they get to help other people and spend a great deal of time interacting with others. Because of their strong communication and organizational skills, ENFJs can make great leaders and managers. They are good at organizing activities, helping each group member achieve their potential and resolving interpersonal conflicts. They strive to create harmony in all situations, and always seem to know what to do to ease tensions and minimize disagreements.

People with this personality type enjoy helping their friends, and it is important to show that you accept and appreciate what they have to offer. However, it is also important that you offer your support in return. ENFJs are not always good at asking for help when they need it. In many cases, simply being willing to listen to whatever they have to share can be very helpful. Parenting Children of ENFJs might find it difficult to live up to their parents high exceptions. At times, the ENFJ parents hands-on approach to parenting can be stifling and make it difficult for kids to explore the world on their own terms. Parents of ENFJ children should recognize that their children are extremely empathetic, sometimes to the point that they may feel overwhelmed by the strong emotions that other people evoke. These children are giving and caring but may find it difficult to burden others with their own struggles. Parents should encourage their children to care for others, while still taking care of their own emotional well-being. Relationships Because ENFJs are so sensitive to the feelings of others, your happiness is critical to your partners happiness. Remember that your partner may even put their own needs last in order to ensure that your needs are met. Let your ENFJ partner know how much you appreciate all the support and care that they offer and be willing to provide the same support in return â" even if he or she struggles to ask for help.

Ethics refers to the principles that influence how a person or a group of people behaves. It is what dictates what is right or wrong but in some cases what may be right to a person may be wrong to another person. The idea of what is right or wrong is influenced by factors of religion, the society, past experience and individual perceptions about different issues (Carroll Buchholtz, 2014). Ethics dictates what values are and the social responsibility that an individual or a group of people play towards the society. The purpose of this article is to discuss the ethical issues that affect the field of organizational behavior. Organizational behavior refers to the study of how people interact with each other in organizational settings and this forms the culture of the organization (McShane Von, 2015). Naturally people are different; the values they uphold and what they consider to be right or wrong differs. Their interests also differ and getting them to unite on a similar background can be very hectic. For this reason, ethical issues have to be considered in an organization so that people treat each other fairly and are able to interact with each other. Among the major ethical issues that affect organizational behavior include health and safety of employees, legal and government compliance, transparency, fair working conditions and technology.

Thousands of species have become extinct over the last four decades as a result of changes in land use and as a result of global warming. Whether or not the millions of species can adapt and evolve to climate changes is debatable. As this brief overview will report, the human species is not adapting well to the changes. It must be remembered that increases in the levels of carbon dioxide are certainly responsible for the risk many species face, but so is the way land is used, e.g., rain forest destruction. There is a feedback loop wherein plant life and the climate are interdependent. Each affects the other. When forests are cut down, temperatures in that area will rise. Rising temperatures cause other plant life requiring coolerÃ¢â¬ ¦show more contentÃ¢â¬ ¦The results of these acts of nature have taken lives; a heat wave in France claimed 15,000 lives (King, 2004) and one in Chicago caused 500 heat related deaths (Journal of Environmental Health, 2001). Carbon dioxide levels are higher than at any time in our history (King, 2004). It is projected that more carbon dioxide will cause these levels to cause increased temperatures by 1.0 degrees to 4.5 degrees Celsius during the next century. Furthermore, climate changes have brought more diseases especially vector borne diseases, like malariaÃ¢â¬ (Journal of Environmental Health, 2001, p. 30). Different attempts have been made to stop global warming or to slow down its progress. For instance, the Kyoto Protocol was signed by numerous countries in 1997 (Retallack, 2000). This agreement called for countries to reduce their greenhouse gas emissions by 2012 (Retallack, 2000). Since that time, the levels identified in this Protocol would do very little in terms of stabilizing the concentration of these gases (Retallack, 2000). In 2001, the Organization for Economic Cooperation and Development (OECD) adopted a 10-year Environmental Strategy (OECD Observer, 2004). In 2004, they acknowledged they are not on track w ith the strategy (OECD Observer, 2004).

string(134) " On the other manus, curdling consequences in a larger mass of primary sludge that is frequently more hard to inspissate and dewater\." Water constitutes over 70 % of the Earths surface and is a really of import resource for all people and the environment. If H2O gets polluted it cant be the elixr of life any longer to aquatic and to the wild life that depend on it. Rivers and watercourses polluted with chemical contaminations account as one of the most important environmental jobs. We will write a custom essay sample on A Comparison Of Wastewater Treatment Methods Environmental Sciences Essay or any similar topic only for you Order Now Water pollution is fundamentally a human fallacy.This used H2O is called Ã¢â¬Å" effluent Ã¢â¬ . Turning population and rapid industrialization has increased the volume of effluent manifold finally deteriorating the fresh H2O resources and environing environment due to inappropriate management.It is 99.94 per centum H2O, with merely 0.06 per centum of the effluent being dissolved and suspended solid stuff. Infiltration/inflow: immaterial H2O that enters the cloaca system through indirect and direct agencies such as through leaking articulations, clefts, or porous walls.Inflow is storm H2O that enters the cloaca system from storm drain connexions, roof headings, foundation and cellar drains or through manhole screens ; Features: Fresh, aerophilic, domestic H2O has been said to hold the smell of kerosine or newly turned Earth. Aged, infected sewerage is well more violative to the olfactory nerves.The characteristic rotten-egg smell of H sulphide and the mercaptans is declarative of infected sewage.Fresh sewerage is typically gray in colour.septic sewerage is black.The category of chemical compounds found in effluent are illimitable and so they are better known by the name of the trial used to mensurate them which are BOD5 and COD test.Industrial procedures generate a broad assortment of effluent pollutants.The features and degrees of pollutants vary significantly from industry to industry. Waste-water quality is assessed based on physical, chemical, and biological features. Physical parametric quantities include coloring materials, smell, temperature, and turbidness. Insoluble contents such as solids, oil and lubricating oil, are to be considered under this category.. Solids may be farther subdivided into suspended and dissolved solids every bit good as organic ( volatile ) and inorganic ( fixed ) fractions. Chemical factors to be considered are: biochemical O demand ( BOD ) , chemical O demand ( COD ) , entire organic C ( TOC ) , and entire O demand ( TOD ) . Inorganic chemical parametric quantities include salt, hardness, pH, sourness and alkalinity, every bit good as concentrations of ionised metals such as Fe and manganese, and anionic entities such as chlorides, sulphates, sulphides, nitrates and phosphates. Bacteriological parametric quantities include coliforms, fecal coliforms, specific pathogens, and viruses. Both components and concentrations vary with clip a nd local conditions. VARYING FLOW Issue: Waste-water flow fluctuates with fluctuations in H2O use, which is affected by a battalion of factors including clime, community size, life criterions, dependableness and quality of H2O supply, H2O preservation demands or patterns, and the extent of metre services, in add-on to the grade of industrialization, cost of H2O and supply force per unit area. Wide fluctuations in effluent flow rates may therefore be expected to happen within a community Effluent does non flux into a municipal effluent intervention works at a changeless rate. The flow rate varies from hr to hr. In most metropoliss, the form of day-to-day activities sets the form of sewerage flow and strength. Above-average sewerage flows and strength occur in mid-morning.The invariably altering sum and strength of effluent to be treated makes efficient procedure operation difficult.Also, many intervention units must be designed for the maximal flow conditions encountered which really consequences in their being oversized for mean conditions.Flow equalisation is non a intervention procedure in itself, but a technique that can be used to better the effectivity of both secondary and advanced effluent intervention processes.The intent of flow equalisation is to stifle the fluctuations so that the effluent can be treated at a about changeless flow rate.Flow equalisation can significantly better the public presentation of an bing works and increase its utile capacity.In ne w workss, flow equalisation can cut down the size and cost of the intervention units. Wastewater intervention options may be classified into groups of procedures harmonizing to the map they perform and their complexness: The basic methods of handling municipal effluent autumn into the undermentioned phases, which is shown in the signifier of block flow: The procedure flow diagram of a basic effluent intervention procedure is as follows: Conventional WASTEWATER TREATMENT PROCESSES: General footings used to depict different grades of intervention in order of increasing intervention degree are preliminary, primary, secondary and third and/or advanced effluent intervention. Preliminary intervention: Preliminary intervention prepares waste-water influent for farther intervention by cut downing or extinguishing non-favourable waste-water features that might otherwise impede operation or overly increase care of downstream procedures and equipment. These features include big solids and shreds, scratchy grit, smells, and, in certain instances, intolerably high extremum hydraulic or organic burdens. Preliminary intervention processes consist of physical unit operations, viz. testing and comminution for the remotion of dust and shreds, grit remotion for the riddance of coarse suspended affair, and floatation for the remotion of oil and lubricating oil. Other preliminary intervention operations include flow equalization, septage handling, and odour control methods. Primary Treatment: Primary intervention is designed to take organic and inorganic solids by the physical procedures of deposit and flotation. About 30 Ã¢â¬â 40 % of the pollutants are removed from the waste Waterss. Primary intervention acts as a precursor for secondary intervention. Secondary intervention: The intent of secondary intervention is the remotion of soluble and colloidal organics and suspended solids that have escaped the primary intervention. This is typically done through biological procedures, viz. intervention by activated sludge, fixed-film reactors, or laguna systems and deposit. Chemical intervention utilizes a coagulator such as Fe or aluminium.Then solid organic affair and P are precipitated into larger pieces which are separated as sludge. Suspended solids removal through chemical intervention involves a series of three unit operations: rapid commixture, flocculation and settling..A once-through chemical intervention system is shown below the tabular array. Advantage: greater remotion efficiency, the feasibleness of utilizing higher overflow rates, and more consistent public presentation. On the other manus, curdling consequences in a larger mass of primary sludge that is frequently more hard to inspissate and dewater. You read "A Comparison Of Wastewater Treatment Methods Environmental Sciences Essay" in category "Essay examples" It besides entails higher operational costs and demands greater attending on the portion of the operator. Adsorption WITH ACTIVATED CARBON Adsorption is the procedure of roll uping soluble substances within a solution on a suited interface. In waste-water intervention, surface assimilation with activated carbon-a solid interface-usually follows normal biological intervention, and is aimed at taking a part of the staying dissolved organic matter.Particulate affair nowadays in the H2O may besides be removed.. The two most common types of activated C are farinaceous activated C ( GAC ) , which has a diameter greater than 0.1 millimeter, and powdered activated C ( PAC ) , which has a diameter of less than 200 mesh. A schematic of an activated C contactor is shown below the tabular array. Advantage: Exploitation powdered activated C in concurrence with traditional biological intervention provides first-class outflowing bio-assay consequences, provides for toxicity control within the bioreactor, and proAÃ motes higher nitrification efficiency than that of a conventional activated-sludge system. CWAO Oxidation is a procedure widely used for effluent intervention by which the pollutants are removed or converted into more biodegradable substances. Catalytic moisture air oxidization ( CWAO ) is a liquid stage reaction between organic stuff in H2O and O. CWAO is an attractive intervention for waste watercourses, which are excessively dilute to incinerate and excessively concentrated for biological intervention. It can be defined as the oxidization of organic and inorganic substances in an aqueous solution or suspension by agencies of O or air at elevated temperatures and force per unit areas. It is besides called flameless burning Typical conditions for CWAO scope from 125 to 300a-Ã ¦C and at force per unit areas from 0.5 to 20 MPa. Residence times may alter from 15 to 120 min, and the chemical O demand ( COD ) remotion may typically be about 75-90 % . DECHLORINATION Dechlorination is the remotion of free and entire combined Cl residue from chlorinated effluent wastewater before its reuse or discharge to having Waterss. Chlorine compounds react with many organic compounds in the wastewater to bring forth unsought toxic compounds that cause long-run inauspicious impacts on the H2O environment and potentially toxic effects on aquatic microorganisms.

Comparison OF CHEMICAL AND BIOLOGICAL PHOSPHORUS REMOVAL IN WASTEWATER: Factor BIOLOGICAL PHOSPHORUS REMOVAL CHEMICAL PHOSPHORUS REMOVAL EFFLUENT QUALITY Biological P remotion was observed to make a lower limit of 0.4mg/l in the wastewater Chemical P remotion was observed to make whatever outflowing quality demand as more and more chemicals are dosed SLUDGE PRODUCTION ( The production of sludge is considered as a really of import factor in the pick of a effluent intervention method presents ) Sludge production is less compared to chemical method. Chemical P remotion produces more sludge, approximately 25 % more sludge than by biological agencies. NEEDED PLANT VOLUME As the volume of the anaerobiotic zone of the Bio -P procedure is reduced, there are alterations in the outflowing quality and the efficiency of P remotion is reduced The decrease of the volume of the anaerobiotic zone has no effects on the chemical P remotion Consumption OF ENERGY It was possible to cut down the capacity of the aeration device down to 1000kg O2/hr and still hold good intervention consequences in footings of COD and nitrogen remotion in the Bio-P process.Beyond this bound ( less than 100kg O2/hr ) COD and the Nitrogen in the wastewater are excessively high. Same sum of COD and Nitrogen in the wastewater is observed at 500kgO2/hr.So chemical method is more immune to decrease in aeration capacity than the Bio-P procedure by atleast 500kgO2/hr aeration capacity. ECONOMIC COST OF TREATMENT ) Annual cost for sludge disposal is saved by Bio-P compared to chemical method. The cost of buying chemicals is high and no nest eggs with respect to sludge disposal compared to Bio-P remotion. The economic cost of intervention has been evaluated based on a summing up of the single costs associated with sludge production, cost of chemicals, energy cost and costs associated to volume nest eggs. The purpose of an economic cost is non to reflect the exact fiscal cost but an estimation that could be used as a guideline for the building of a new works or for comparing of the two procedures. Discussion: Chemical VS BIOLOGICAL TREATMENT: Biological procedure removes solid organic affair and dissolved organic affair. The chemical procedure removes solid organic affair and phosphorus.Chemical precipitation cleans the H2O really quickly, say in less than 15mins after the induction of the procedure, we have clean H2O, whereas with biological intervention it will take 3 hour to accomplish the same.Biological procedure stopping points relatively long clip and is dependent on the effectivity of the microorganisms.Chemical and Biological interventions work in different ways and accomplish different results.We have to find the major causes of O lack in Waterss and choose the intervention in conformity with local environmental requirements.Purification in itself demands resources.Biological intervention requires a long abode clip and energy is consumed when air is blown into the sewerage water.Consequently the Biological works is large and more complex.The micro-organisms have to be adapted to the pollution which sensitises th e whole system.Chemical purification requires add-on of coagulators which is done in a little pool and at lower energy consumption.The entire energy used for chemical intervention is merely 15 % of that required for biological intervention, even if the energy used for production and distribution of coagulators is included.In footings of the entire ecological emphasis, the chemical procedure is favoured.Life rhythm appraisals show the biological procedure to be a larger consumer of resources and therefore it is more negative interms of its full environmental impact.If there is no demand to take dissolved organic affair a biological procedure could make greater ecological harm than chemical procedure due to the entire energy ingestion and the natural stuffs used when building the works. The environment makes demands on the purification procedure and if advanced purification is necessary both biological and chemical methods must be used..In Norway, the bing chemical works built wholly within bedrock was extended with the N remotion system due to the increased food load.With the alone combination of chemical and biological procedures this works occupies less than half the volume of the conventional biological procedure. CONCLUSION AND RECOMMENDATIONS: Effective effluent aggregation and intervention are of great importance from the point of view of both environmental and public wellness. Any effluent intervention works needs important investing and Operation Maintenance and control, and hence any determination to implement such a installation should be carefully considered. It is non a good thought to reason that any intervention method is better than the other.Each one has its ain advantages and disadvantages.The pick of which method is to be used will depend on the society, the discharge demands and the costs they are ready to incur.As a concluding decision, the winning construct these yearss should non be based on which procedure should be used in isolation to the other, but instead utilizing the advantages of both processes together to obtain best consequences, while at the same clip understating their disadvantages. Extensive research activity in this field has led to important betterment and variegation in the procedures and methods used for waste-water intervention and sludge direction. Public wellness jeopardies are frequently associated with waste-water reuse, and accordingly it is indispensable to circulate cognition and information about the danger of natural waste-water reuse and issue safe reuse guidelines.

Strong, intelligent, capable, good, and kind, he is the most heroic figure in the novel that bears his name. Tom's most important characteristic is his Christian faith. God has given Tom an extraordinary ability. He can forgive the evil done to him. His self-sacrificing love for others has been called motherly. It has also been called truly Christian. AUNT CHLOE- Aunt Chloe, Uncle Tom's wife, is fat, warm, and jolly. She is a good housekeeper and a superb cook, and justly proud of her skill. She loves Tom, and urges him to escape to Canada rather than to go South with Haley. After Tom is sold, she convinces the Shelbys to hire her out to a baker in Louisville and to use her wages to buy Tom's freedom. She is heartbroken to learn of his death. - MOSE, PETE, AND POLLY - Mose, Pete, and Polly, the children of Uncle Tom and Aunt Chloe, are playful and rambunctious. Polly is Tom's special favorite, and she loves to bury her tiny hands in his hair. ELIZA HARRIS - Eliza Harris is raised by her mistress, Mrs. Shelby, to be pious and good. Described as light-skinned and pretty, Eliza dearly loves her husband, George Harris, and their little boy, Harry. When she learns that Harry is about to be sold, Eliza carries him in her arms to the Ohio River, which she crosses on cakes of ice. Although generally a modest and retiring young woman, Eliza becomes extraordinarily brave because of her love for her son. GEORGE HARRIS- George Harris, portrayed as a light-skinned and intelligent slave, belongs to a man named Harris. He is married to Eliza, who lives on the Shelby plantation, and they have a son, Harry. HARRY AND LITTLE ELIZA - Harry and little Eliza are the children of George and Eliza Harris. Harry, born a slave on the Shelby Plantation, is bright and cute, and sings and dances for Mr. Shelby and Haley. He is so beautiful that he is disguised as a girl in order to escape into Canada. Once there, he does very well in school. Little Eliza is born free in Canada. - SAM AND ANDY- Sam and Andy, slaves on the Shelby plantation, provide comic relief through their mispronunciations and deliberate mishaps. Andy, who likes to makes speeches, is meant to satirize politicians. But Sam and Andy make an important contribution to the novel's plot- their clowning allows Eliza to escape across the Ohio River. MR. SHELBY - Mr. Shelby, the owner of a Kentucky plantation, generally treats his slaves well, but he decides to sell two of them, Uncle Tom and little Harry, to pay off a debt. Although he regrets the sale, Shelby feels he has no other choice. MRS. SHELBY - Mrs. Shelby, a kind, religious woman, tries to raise the family's slaves with Christian values. She attempts to convince her husband not to sell Tom and Harry, and she helps Eliza escape. Warm-hearted Mrs. Shelby treats her slaves like people, crying with Aunt Chloe when Uncle Tom leaves and consoling her when they learn he is dead. - GEORGE SHELBY- George Shelby, the son of Mr. and Mrs. Shelby, is thirteen years old when the novel begins, and eighteen when it ends. He likes to spend time with Uncle Tom and Aunt Chloe, basking in their kindness and attention. He teaches Uncle Tom to read and write, and reads the Bible at the slaves' religious meeting. On Uncle Tom's grave, he swears to do whatever he can to fight against slavery, and he begins by freeing the slaves on his own plantation. George is one of the few characters who changes during the course of Uncle Tom's Cabin, as he develops from a good-hearted but somewhat self-centered boy into a noble and effective man. HALEY-Haley sets the plot of Uncle Tom's Cabin in motion by insisting that Mr. Shelby sell him Tom and little Harry. Haley curses, smokes, drinks, and dresses badly. He claims to be humane because he is not completely cruel to the slaves he buys. But you can see that he's a nasty person. He doesn't believe slaves have feelings, so he doesn't think twice about separating a mother and child- like Eliza and little Harry, or about the woman who

Three Races to Immigrate to the United States In Search for the Promised Land Introduction: The Mystery of the United States It seems that the USA has become the Promised Land for the people dissatisfied with the quality of living standards in their own country; therefore, these people head to their Mecca, the country where every cloud has a silver lining. In the light of the fact that at present, a number of the USA cities are overpopulated, the issue concerning immigration remains unresolved.Advertising We will write a custom essay sample on Three Races to Immigrate to the United States: In Search for the Promised Land specifically for you for only $16.05 $11/page Learn More Unless the given issue is tackled, immigration into the USA might soon become impossible. Therefore, it is necessary to consider what races are most likely to immigrate to the USA in the nearest future, as well as which of these races have the most legitimate reasons to be accepted into the realm of the USA democracy. When the Oriental Culture Merges with the We stern One: The Chinese The first candidates to migrate to the United States, the Chinese, nevertheless, are bound to face a number of difficulties when acculturating to the American lifestyle and trying to build their own mini-society within the realm of the American culture. However, it seems that the Chinese actually integrated into the American society quite a while ago. According to the existing evidence, the concept of an AmericanÃ¢â¬âChinese culture emerged in the distant 1850, when the first immigration wave swept New York and other major cities (Liu). In addition, it is noteworthy that the Americans have been maintaining business relationships with the Chinese for quite long. That being said, it would be reasonable to suggest that the Chinese migrant population is bound to find a common language with the Americans at least in the business field. In Search for Better Working Options: The Mexicans There is no point in denying that the economical and financial state of Mexic o is more than deplorable. The state remains on the list of the so-called third world countries, and with the budget that the government has at the disposal, as well as the policy of the state, there seems to be no way out at present. According to the existing evidence, most of the Mexican population lives beyond the poverty threshold (Ceballos and Palloni). Therefore, it seems rather fair that the Mexican people should search for the place where their professional assets and efforts are going to be evaluated fairly and paid accordingly. However, when considering the migration of the Mexicans into the United States, one rarely takes the possible results into account. To start with, the process of acculturation is bound to take a considerable amount of time. In addition, it is highly recommended that immigrants into the United States, as well as any other state of the world, should perfect their professional skills in order to remain well paid and become successful.Advertising Looking for essay on rhetoric?

Pushing the Science to Its Limits: The Russians and the Brain Drain Naturally, when analyzing the reasons that make people from other countries move to the United States, people rarely consider the possible contributions of the immigrants into the American culture, science and society. When thinking of the opportunities that the so-called Ã¢â¬Å"brain drainÃ¢â¬ from other states to the USA offers to the latter, it is also necessary to evaluate the quality of education in the state, which the i mmigrants come from. According to the latest research, compared to the USA standards, the greatest quality of education can be observed in such countries as New Zealand and South Korea (Miller, Laugesen, Lee and Mick). In the light of the fact that over the past few years, the standards of living in the new Zealand have dropped and a number of people have been considering the option of moving to the United States, it will be reasonable to allow the New Zealanders become the residents of the United States of America. The given situation will be a graphic example of a reciprocal process that has to take place between the receiving country and the immigrating nation. The same can be said about the residents of South Korea; according to the existing researches, they have very high educational standards. However, when choosing between the two nations, one must mention that the South Korean living standards are much higher than the ones of New Zealand at present, which means that the New Zealanders need the USA assistance more. That being said, the immigration of the New Zealanders into the USA should be considered. Conclusion: Acculturation, Togetherness and Other Related Issues There is no doubt that the USA offers a plethora of opportunities for people to develop professionally, contributing to the state and being able to run their own business, at the same time maintaining their national and cultural identity. However, the problems of acculturation and the loss of identity are still worth bringing up. No matter how well developed the structure of a diaspora is, its members will still be isolated from their culture, which will inevitably lead to the loss of cultural roots. Therefore, immigration will always presuppose a dilemma between economical independence and national identity.Advertising We will write a custom essay sample on Three Races to Immigrate to the United States: In Search for the Promised Land specifically for you for only $16.05 $11/page Learn More Ceballos, Miguel and Alberto Palloni.

Calculating Concentrations with Units and Dilutions Calculating the concentration of a chemicalÃ solutionÃ is a basic skill all students of chemistry must develop early in their studies. What is concentration? Concentration refers to the amount of solute that is dissolved in a solvent. We normally think of a solute as a solid that is added to a solvent (e.g., adding table salt to water), but the solute could easily exist in another phase. For example, if we add a small amount of ethanol to water, then the ethanol is the solute, and the water is the solvent. If we add a smaller amount of water to a larger amount of ethanol, then the water could be the solute! How To Calculate Units of Concentration Once you have identified the solute and solvent in a solution, you are ready to determine its concentration. Concentration may be expressed several different ways, using percent composition by mass, volume percent, mole fraction, molarity, molality, or normality. Percent Composition by Mass (%)This is the mass of the solute divided by the mass of the solution (mass of solute plus mass of solvent), multiplied by 100.Example:Determine the percent composition by mass of a 100 g salt solution which contains 20 g salt.Solution:20 g NaCl / 100 g solution x 100 20% NaCl solutionVolume Percent (% v/v) Volume percent or volume/volume percent most often is used when preparing solutions of liquids. Volume percent is defined as:v/v % [(volume of solute)/(volume of solution)] x 100%Note that volume percent is relative to the volume of the solution, not the volume of solvent. For example, wine is about 12% v/v ethanol. This means there is 12 ml ethanol for every 100 ml of wine. It is important to realize liquid and gas volumes are not necessarily additive. If you mix 12 ml of ethanol and 100 ml of wine, you will get less than 112 ml of solution.As another example, 70% v/v rubbing alcohol may be prepared by taking 700 ml of isopropyl alcohol and adding su fficient water to obtain 1000 ml of solution (which will not be 300 ml). Mole Fraction (X) This is the number of moles of a compound divided by the total number of moles of all chemical species in the solution. Keep in mind, the sum of all mole fractions in a solution always equals 1.Example:What are the mole fractions of the components of the solution formed when 92 g glycerol is mixed with 90 g water? (molecular weight water 18; molecular weight of glycerol 92)Solution:90 g water 90 g x 1 mol / 18 g 5 mol water92 g glycerol 92 g x 1 mol / 92 g 1 mol glyceroltotal mol 5 1 6 molxwater 5 mol / 6 mol 0.833x glycerol 1 mol / 6 mol 0.167Its a good idea to check your math by making sure the mole fractions add up to 1:xwater xglycerol .833 0.167 1.000Molarity (M) Molarity is probably the most commonly used unit of concentration. It is the number of moles of solute per liter of solution (not necessarily the same as the volume of solvent!).Example:What is the molarity of a solution made when water is added to 11 g CaCl2 to make 100 mL of solution ? (The molecular weight of CaCl2 110)Solution:11 g CaCl2 / (110 g CaCl2 / mol CaCl2) 0.10 mol CaCl2100 mL x 1 L / 1000 mL 0.10 Lmolarity 0.10 mol / 0.10 Lmolarity 1.0 M Molality (m) Molality is the number of moles of solute per kilogram of solvent. Because the density of water at 25Ã °C is about 1 kilogram per liter, molality is approximately equal to molarity for dilute aqueous solutions at this temperature. This is a useful approximation, but remember that it is only an approximation and doesnt apply when the solution is at a different temperature, isnt dilute, or uses a solvent other than water.Example:What is the molality of a solution of 10 g NaOH in 500 g water? (Molecular weight of NaOH is 40)Solution:10 g NaOH / (40 g NaOH / 1 mol NaOH) 0.25 mol NaOH500 g water x 1 kg / 1000 g 0.50 kg watermolality 0.25 mol / 0.50 kgmolality 0.05 M / kgmolality 0.50 mNormality (N) Normality is equal to the gram equivalent weight of a solute per liter of solution. A gram equivalent weight or equivalent is a measure of the reactive capacity of a given molecule. Normality is the only concentration unit that is reaction dependent.Example:1 M sulfuric acid (H2SO4) is 2 N for acid-base reactions because each mole of sulfuric acid provides 2 moles of H ions. On the other hand, 1 M sulfuric acid is 1 N for sulfate precipitation, since 1 mole of sulfuric acid provides 1 mole of sulfate ions. Grams per Liter (g/L)This is a simple method of preparing a solution based on grams of solute per liter of solution.Formality (F)A formal solution is expressed regarding formula weight units per liter of solution.Parts per Million (ppm) and Parts per Billion (ppb)Used for extremely dilute solutions, these units express the ratio of parts of solute per either 1 million parts of the solution or 1 billion parts of a solution.Example:A sample of water is found to contain 2 ppm lead. This means that for every million parts, two of them are lead. So, in a one gram sample of water, two-millionths of a gram would be lead. For aqueous solutions, the density of water is assumed to be 1.00 g/ml for these units of concentration. How To Calculate Dilutions You dilute a solution whenever you add solvent to a solution. Adding solvent results in a solution of lower concentration. You can calculate the concentration of a solution following a dilution by applying this equation: MiVi MfVf where M is molarity, V is volume, and the subscripts i and f refer to the initial and final values. Example:How many milliliters of 5.5 M NaOH are needed to prepare 300 mL of 1.2 M NaOH? Solution:5.5 M x V1 1.2 M x 0.3 LV1 1.2 M x 0.3 L / 5.5 MV1 0.065 LV1 65 mL So, to prepare the 1.2 M NaOH solution, you pour 65 mL of 5.5 M NaOH into your container and add water to get 300 mL final volume
