Insulting Language and Swear Words free essay sample

Has insulting become a Nowadays the use of swear-words has become a normal form of speech among population, and probably even more extensive among teenagers. The reasons why insulting is so widespread in modern society may range substantially amongst the different social groups in which society is stratified. It is clear that nowadays insulting might seem to be more natural than some decades before, but this fact becomes very clear once we take into account the evolution concerned to freedom of speech. This aspect does not mean that insulting is something new in todays culture; using swear words in our daily speech is as ancient as life itself, but because of the abovementioned freedom of speech, we are used to hearing or reading this part of our vocabulary in any circumstance, whether on television or on radio or on any situation. One of the main means for the use and, consequently, for the learning of these words is television. We will write a custom essay sample on Insulting: Language and Swear Words or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page It is almost impossible not to watch a film or a television aerogram in which a swear word is not mentioned.It is on television where people learn not only the meaning of swear words but also the situation In which has to, or might, be used. A very different aspect is to try to analyses whether insulting has become a habit In our society or Just a mean of showing different emotions before a particular situation. Insulting Is not Just using words with more or less strength in their meaning, but it also Implies a deliberate Increase in the tone of the utterance.By intensifying the tone of our speech when we Insult means an attempt to let clear the seriousness of our Intimidation or threaten. To affirm that Insulting has turned out to be a habit In the use of language In modern society might represent a risky statement, but It Is clear that Is not unusual or strange to hear these sorts of words In any situation because all In all they are part of the richness of our vocabulary. What should be analyses Is to try to explain to what extend the use of these words are necessary.

The continuing foreign control over much of china, and ever-increasing influence of Japan doomed china for a state of political and social destress from 1911 to communist victory of 1914

The continuing foreign control over much of china, and ever-increasing influence of Japan doomed china for a state of political and social destress from 1911 to communist victory of 1914 On January first, 1912 the Republic of China was established, signaling the end of the Manchu-dominated Qing Empire. Sun Yat-sen of the Kuomintang, was proclaimed provisional president of the republic. However, Yuan Shikai, a former Qing general who had defected to the revolutionary cause, soon forced Sun to step aside and took the presidency for himself. For the years to come up until the Communist Victory in 1949, the Country of China was faced with various levals of policital distress. Increasing pressure from neighbour Japan, as well as the selfish betrayal of the Republics well being by political leaders Yuan Shikai and Chiang Kaishek lead to a testing time for the Country.Thanks to strong military backup, Yuan was officially swarn in as President of the Chinese Republic on the 10th of October 1913. He had gradually dissolved the provincial and national paliaments thus leaving him the unchallanged dictator of China.Yuan Shikai sworn in as Provisional President of t...Yuan was Th e President of the Republic of China for a short period of time, due to his death at age fifty-six of Kidney failture on June 6th 1915.

When Japan fronted the Twenty One Demands in 1915 he accepted the main demands, resulting in nationwide protest. The Chinese people were outraged when...

The Black Codes and Why They Matter Today

The Black Codes and Why They Matter Today It’s hard to understand why African Americans are incarcerated at higher rates than other groups without knowing what the black codes were. These restrictive and discriminatory laws criminalized blacks after slavery and set the stage for Jim Crow. They are also directly linked to today’s prison industrial complex. Given this, a better grasp of the Black Codes and their relationship to the 13th Amendment provides a historical context for racial profiling, police brutality, and uneven criminal sentencing. For far too long, blacks have been dogged by the stereotype that they’re inherently prone to criminality. The institution of slavery and the Black Codes that followed reveal how the state essentially penalized African Americans just for existing. Slavery Ended, but Blacks Weren’t Truly Free During Reconstruction, the period that followed the Civil War, African Americans in the South continued to have work arrangements and living conditions nearly indistinguishable from those they had during slavery. Because the cost of cotton was so high at this time, planters decided to develop a labor system that mirrored servitude. According to America’s History to 1877, Vol. 1: â€Å"On paper, emancipation had cost the slave owners about $3 billion - the value of their capital investment in former slaves - a sum that equaled nearly three-fourths of the nation’s economic production in 1860. The real losses of planters, however, depended on whether they lost control of their former slaves. Planters attempted to reestablish that control and to substitute low wages for the food, clothing, and shelter that their slaves had previously received. They also refused to sell or rent land to blacks, hoping to force them to work for low wages.† The enactment of the 13th Amendment only amplified the challenges of African Americans during Reconstruction. Passed in 1865, this amendment ended the slave economy, but it also included a provision that would make it in the South’s best interest to arrest and imprison blacks. That’s because the amendment prohibited slavery and servitude, â€Å"except as a punishment for crime.† This provision gave way to the Black Codes, which replaced the Slave Codes, and were passed throughout the South the same year as the 13th Amendment. The codes heavily infringed on the rights of blacks and, like low wages, functioned to trap them in a slave-like existence. The codes were not the same in every state but overlapped in a number of ways. For one, they all mandated that blacks without jobs could be arrested for vagrancy. The Mississippi Black Codes in particular penalized blacks for being â€Å"wanton in conduct or speech, neglect[ing] job or family, handl[ing] money carelessly, and ...all other idle and disorderly persons.† How exactly does a police officer decide how well a person handles money or if he’s wanton in conduct? Clearly, many of the behaviors punishable under the Black Codes were completely subjective. But their subjective nature made it easier to arrest and round up African Americans. In fact, a variety of states concluded that there were certain crimes for which only blacks could be â€Å"duly convicted,† according to The Angela Y. Davis Reader. Therefore, the argument that the criminal justice system works differently for whites and blacks can be traced back to the 1860s. And before the Black Codes criminalized African Americans, the legal system deemed runaway slaves fugitives for stealing property - themselves!   Fines, Forced Labor, and the Black Codes Violating one of the Black Codes required offenders to pay fines. Since many African Americans were paid low wages during Reconstruction or denied employment at all, coming up with the money for these fees all too often proved impossible. Inability to pay meant that the county court could hire out African Americans to employers until they worked off their balances. Blacks who found themselves in this unfortunate predicament usually did such labor in a slavery-like environment. The state determined when offenders worked, for how long and what kind of work was performed. More often than not, African Americans were required to perform agricultural labor, just as they had during slavery. Because licenses were required for offenders to perform skilled labor, few did. With these restrictions, blacks had little chance to learn a trade and move up the economic ladder once their fines were settled. And they could not simply refuse to work off their debts, as that would lead to a vagrancy charge, resulting in more fees and forced labor. Under the Black Codes, all African Americans, convicts or not, were subject to curfews set by their local governments. Even their day-to-day movements were heavily dictated by the state. Black farm workers were required to carry passes from their employers, and meetings blacks took part in were overseen by local officials. This even applied to worship services. In addition, if a black person wanted to live in town, they had to have a white sponsor. Any African Americans who skirted the Black Codes would be subject to fines and labor. In short, in all areas of life, blacks lived as second class citizens. They were emancipated on paper but certainly not in real life. A civil rights bill passed by Congress in 1866 sought to give African Americans more rights. The bill, for example, permitted them to own or rent property, but it stopped short of giving blacks the right to vote. It did, however, allow them to make contracts and bring their cases before courts. It also enabled federal officials to sue those who violated the civil rights of African Americans. But blacks never reaped the benefits of the bill because President Andrew Johnson vetoed it.   While the president’s decision dashed the hopes of African Americans, their hopes were renewed when the 14th Amendment was enacted. This legislation gave blacks even more rights than the Civil Rights Act of 1966 did. It declared them and anyone born in the United States to be citizens. Although it did not guarantee blacks the right to vote, it  gave them â€Å"equal protection of the laws.† The 15th Amendment, passed in 1870, would give blacks suffrage. The End of the Black Codes By the end of the 1860s, many Southern states repealed the Black Codes and shifted their economic focus away from cotton farming and onto manufacturing. They built schools, hospitals, infrastructure and asylums for orphans and the mentally ill. Although the lives of African Americans were no longer dictated by the Black Codes, they lived separately from whites, with fewer resources for their schools and communities. They also faced intimidation by white supremacist groups such as the Ku Klux Klan when they exercised their right to vote. The economic woes blacks faced led to an increasing number of them to be incarcerated. That’s because more penitentiaries in the South were built along with all of the hospitals, roads, and schools. Strapped for cash and unable to get loans from banks, former slaves worked as sharecroppers or tenant farmers. This involved working other people’s farmland in exchange for a small cut of the value of the crops grown. Sharecroppers frequently fell prey to shopkeepers who offered them credit but charged exorbitant interest rates on farm supplies and other goods. Democrats at the time made matters worse by passing laws that allowed merchants to prosecute sharecroppers who couldn’t pay their debts. â€Å"Indebted African American farmers faced imprisonment and forced labor unless they toiled on the land according to the instructions of the merchant-creditor,† states America’s History. â€Å"Increasingly, merchants and landlords cooperated to maintain this lucrative system, and many landlords became merchants. The former slaves had become trapped in the vicious circle of debt peonage, which tied them to the land and robbed them of their earnings.† Angela Davis laments the fact that black leaders of the time, such as Frederick Douglass, did not campaign to end forced labor and debt peonage. Douglass primarily focused his energies on bringing an end to lynching. He also advocated for black suffrage. Davis asserts that he may not have considered forced labor a priority due to the widespread belief that incarcerated blacks must have deserved their punishments. But African Americans complained that they were frequently jailed for offenses for which whites were not. In fact, whites usually eluded prison for all but the most egregious crimes. This resulted in blacks jailed for petty offenses being incarcerated with dangerous white convicts. Black women and children were not spared from prison labor. Children as young as 6 years old were  forced to work, and incredibly women in such predicaments were not segregated from male inmates, making them vulnerable to sexual abuse and physical violence at the hands of both convicts and guards. After taking a trip to the South in 1888, Douglass witnessed firsthand the effects of forced labor on the African Americans there. It kept blacks â€Å"firmly bound in a strong, remorseless and deadly grasp, a grasp from which only death can free [them],† he noted. But by the time Douglass made this conclusion, peonage and convict leasing had been in effect for more than 20 years in certain places. And in a short stretch of time, the number of black prisoners grew rapidly. From 1874 to 1877, Alabama’s prison population tripled, for example. Ninety percent of new convicts were African American. Crimes formerly considered low-level offenses, such as cattle theft, were reclassified as felonies, ensuring that impoverished blacks found guilty of such crimes would be sentenced to longer prison terms. African American scholar W.E.B. DuBois was disturbed by these developments in the prison system. In his work, Black Reconstruction, he observed, â€Å"The whole criminal system came to be used as a method of keeping Negroes at work and intimidating them. Consequently there began to be a demand for jails and penitentiaries beyond the natural demand due to the rise of crime.† Legacy of the Black Codes Lives On Today a disproportionate amount of black men are behind bars. In 2016, the Washington Post reported that 7.7 percent of black men between the ages of 25 to 54 are institutionalized compared to 1.6 percent of white men. The newspaper also stated that the prison population has quintupled over the past four decades and that one out of nine black children has a parent in prison. Many ex-convicts can’t vote or get jobs after their release, increasing their chances of recidivism and trapping them in a cycle as relentless as debt peonage. A number of social ills have been blamed for the large numbers of blacks in prison - poverty, single-parent homes and gangs. While these issues may be factors, the Black Codes reveal that since slavery ended those in power have used the criminal justice system as a vehicle to strip African Americans of their liberty. This includes the glaring sentencing disparities between crack and cocaine, a higher police presence in black neighborhoods, and a bail system that requires those  arrested to pay for their release from jail or remain incarcerated if they’re unable to. From slavery onward, the criminal justice system has all too often created insurmountable hurdles for African Americans.

Capital Asset Pricing Model Assignment Example | Topics and Well Written Essays - 1000 words

Capital Asset Pricing Model - Assignment Example Usually, the overall volatility of the market is measures through proxies when implementing this model, for instance, the use of FTSE index. Such proxies are not usually the true measures of the market volatility which is at the core of the CAPM assumptions. Therefore, the model estimations from CAPM with use of market proxies for volatility can only predictions that are approximates and not the accurate measures of risk and return relationships. Another unrealistic assumption the CAPM model makes is the existence of a free risk security. In reality, there is not security that is free from risk. Usually, researchers use government security as a risk free security. The truth is while the government may not default (thus considered no risk), other factors such as inflation are uncertain and may impact on the real rate of return. There is also the assumption in the CAPM that the lending and borrowing rates are equal. In reality, this is incorrect as these rates usually differ. The model also makes an assumption that investors will hold highly diversified portfolios. This is not always the case as investors may not hold such highly diversified portfolios and therefore the entire market indices may not be well diversified. This therefor affects the results of CAPM model in estimating market returns. It is therefore unlikely, given these assumptions, that investors behaviour can be accurately explained by this model and also accurately measure the risk of investment. Another limitation of the CAPM model is that given the assumptions it makes, it is difficult to establish its practical validity as well as its empirical validity. Empirical results on whether there is a significant relationship between beta and expected return has been mixed. For instance, some studies have found positive but weak correlations. Others have revealed that returns were not only related to betas but also with other risks such as firm specific risks. Further, other studies find no relationsh ip between beta and returns. Returns have also been found to be highly correlated with other factors such as size of the firms, market and book value ratios, among other factors. These call for need to establish whether beta can be used to measure the risk of securities and whether it is correlated with expected return. Without this, practical and empirical validity cannot be assumed. Another conceptual problem that is linked to validity is the fact that empirical studies on CAPM model have used actual past data and not expected prices to test the model. This introduces bias and there is need to use expected prices to test the model to examine its validity. Another assumption of capital asset pricing model is that betas are assumed to remain stable over time. This is not possible. From the model, beta is a measure of future risk of securities. Investors on the other hand only have past data of share prices and market portfolios, and not future data. Beta can therefore only be estima ted from past data. When past data is used to measure beta, such beta can only be a reliable measure of future risk if it can remain stable over time. This is not possible as studies have found that individual securities do not remain stable over time. Therefore, historical betas are not good predictors of future risk of securities. Describe Roll’s critique of the early empirical tests of the CAPM. Roll has two issues with the CAPM model. The first criticism is stemmed from one of the

Food Conflict in the World Research Paper Example | Topics and Well Written Essays - 2500 words

Food Conflict in the World - Research Paper Example In addition, intensive subdivision of land has made it very hard for these people to produce enough food to support their family (Runge, 2003). The subdivision of land has created more conflicts as there are no documents that were used during land adjudication. Family wrangles have therefore slowed the production process. This is affecting the level of food security in the society. With the increasing levels of globalization resulting from liberalization of markets, efficient flow of information, and integration of economies, the conflicts of interest in the global market has increased tremendously. The multinational companies have shifted their attention towards the agricultural sector as a way of diversifying their source of revenues. This is to reduce the risks and uncertainties associated with focusing on a single product. However, majority of these firms have no interest of the people at hand. Instead, they venture in agriculture in order to make immense profits at the expense of poor farmers. They have therefore leased large tracks of land which have the potential to produce enough foods for the population. They then plant cash crops such as flowers which fetch high prices in the global market. They go ahead and hire a lot of employees who have the necessary skills and experience to produce food for the population (Labonte, 2009). This aspect is negativel y affecting the agricultural sector. Globalization has led to the liberalization of market, an aspect that has a major impact on food security in the world.

Development of Emulsion Property

Development of Emulsion Property Student’s name: Yang Jiang Abstract In recent years, emulsion has taken an important port in our life, such as cosmetic and some other cosmetic industries. The property of the emulsion has a direct impact on our daily life. This paper chose the process of produce bath gel to provide what makes the property change, how to control it and how to make it better. In technically, chose different viscosity, speed rate and concentrate to get different product. Aim to find the best one. Introduction An emulsion is formed when two more insoluble phases are blended together with one of them is in the form of liquid drop. Emulsions belong to a two-phase system ofmatter which is calledcolloids. The emulsion is generally non-transparent and inherently unstable. The diameter of drop is between 100nm to 10mm, and the size of it could be observed by an optical microscope. However in this work, an emulsion consisting of two liquids is the objective many companies and institutions tend to take advantages of. To sum up, two types of this emulsion can be formed by mixture. The one which shapes into a water-in-oil system is called W/O emulsion and another is oil-in-water system which is called O/W emulsion. Emulsion is widely used in manufacturing as a common form of formulated products, and whose properties have been studied in agriculture, medicine, cosmetics and food. Some kinds of emulsion are necessities in daily life, such as: milk, ice cream, vinaigrettes, rubber, latex, crude oil emulsions and even some cutting fluids formetal working. However, an emulsion cannot be obtained easily because emulsions cannot be formed spontaneously. Energy is needed to form an emulsion through shaking, stirring, homogenizing or exposure to power ultrasound. And in this proposal, the emulsion is formed by stirring. Some mixing devices will be adopted to blend Silicon oil and water together. So it is apparent that some parameters can be fixed as constant and the others are what we are interested in to investigate. A number of the physicochemical properties of emulsions can only be understood with reference to their dynamic nature. Many properties depend on the volume fraction of both phases and the type of emulsifier present. Because of the low solubility of oil in water it is usually assumed that the oil in an emulsion droplet is isolated from that in neighboring droplets. Emulsion stability refers to as the ability of resisting change in its properties over time. Coalescence happens when droplets crash into each other and combine to form a larger droplet, so the mean droplet size increases over time. Emulsions can also undergocreaming, in which the droplets rise to the top of the emulsion. In order to keep the emulsion stability, an appropriate surface active agent should be decided to add into the system to increase the kinetic stability of an emulsion so that the size of the droplets keep unchangeable significantly with time. The emulsions produced by dispersion of a liquid into another insoluble liquid is an aspect of great benefits in cosmetic, pharmaceutical, chemical, and food industries. Present industrial methods applied in emulsification processes have been fully developed and studied. For example, rotor stator devices, and static mixers techniques are well-accepted as important ways of producing small droplets but with another side effects on the liquids, bringing potential hazards to the properties of compounds. It has been proved by plenty of researchers that droplet size is one factor of the most difficult ones to control because some instability phases will be produced among this during the controlling process. Rotor-stator mixers are usually used for processing of disperse/break solid particles and aggregates and also to colloidal liquid-liquid systems. Such as cosmetic, food, pharmaceutical, health care products and many other industries. As the drop size affects the processing and the properties of the products in the emulsification. The mechanisms that break the drops is the key for design process. Rotor and stator are the two main mechanisms which can break drops in rotor-stator devices. For emulsification, the industrial processing and some of the product properties are influenced by the drop size. In a two-phase process, the mass transfer rate is proportional to the interfacial area between the two phases. The drop size distribution is varied with the conditions inside the vessel and the length of mixing time and thus the interfacial area is changed with it. Hence successful processing steps are designed by establishing deep understanding of the mechanism of drop breakup. In general, two competing theories have been proved on drop breakup mechanisms to give a good explanation to this phenomenon. So one theory shows that droplet breakup is produced by turbulent eddies (energy dissipation rate) and another is due to the agitator shear rate. Another widely used mixing device: static mixers, which are also called motionless mixers, have become standard equipment in the process industries. Their application in continuous processes is a good choice to traditional agitation because generally better performance can be obtained with this device at lower cost. There are also some other kinds of mixing devices such as CSTR and batch reactor. But according to the cost, property of the emulsion, the conditions in the lab and many other factors I chose rotor-stator mixer as the agitator. The working principle of rotor-stator mixture is shown as below in Figure 1. Figure 1: Basic principle of rotor – stator mixture when running In this essay, comparing different emulsion got from different conditions of the mixing due to different conditions of mixing have a direct result that the droplet size changed. The property of the emulsion is influenced by the droplet size. The viscosity and storage modulus of W/O and O/W fine concentrated emulsions were increased by the reduction of droplet size. And the shear-thinning effects got stronger in the fine emulsions As silicon oil is the resource which is manly used in cosmetics. How bath gel be different by the different size of droplet is the main purpose. As the rheology of emulsion is influenced by the droplet size, various of bath gel might be produced with different property. Background 3.1Theory 3.2. Literature review There have been a large amount of methods of producing polymer emulsions in industrial manufacturing. One of the mainly way of them is emulsion polymerization. Emulsion polymerization has large polymer relative molecular mass, fast reaction rate, low pollution and the equipment and technology with which to produce the emulsion products is easy to get and operated in generation. Recently, more and more scientists have focused on this area. Many factors have an important influence on both yield and quality of the polymerization product in the process of emulsion polymerization, such as the type and concentration of emulsifier, the sorts and concentration of initiator, the intensity of stirring, reaction temperature, the category and concentration of electrolyte and some other technological parameters. Emulsion polymerization system is a multiphase system, the effect of stirring turn the monomer into droplet separately, which is good for heat transfer and mass transfer. And keep the system mixing, constant temperature, avoid from local overheating. The yield and quality of the emulsion polymer are controlled by stir directly. Many scholars carried out extensive research on the influence of the mixing of emulsion polymerization. Such as Shunmukhan et al, Omi et al, Nomura et al who had studied the effects of mixing on low solid content of the emulsion. Vanderhoff, M. Zubitor, S. Oprea et al, Matejicek et al who has studied the effects of mixing on high solid content emulsion polymerization (> 50%).This paper elaborated how the mixing effects on the quality of products. Influence of the style of agitator on polymerization The production capacity of reactor, the quality of product and the accident caused by cooling or heating are all related to the type of agitator. Shearing action, circulating mode and the mixed-ability which were generated by mixing are given by the specific style of agitator. And so does the state of macro-flow. 3 factors should be considered when selecting the style of agitator: 1. High heat transfer coefficient should be ensure from the reactor wall or Immersion coil to the reactants; 2. An obvious effect should be provided in the stirring; 3. Low consumption of energy in the stirring. Therefore, in the process of emulsion polymerization, especially for the industrialized production, we should find out the most appropriate style of agitator by strengthen the research about the relation between mixer and emulsion polymerization. Influence of mixing intensity on the emulsion polymerization 2.1 The influence of mixing intensity on latex particle size In the process of emulsion polymerization, mixing intensity has a direct impact on the latex particle size. With the revolution of mixing higher, monomer was divided into smaller beads, the surface area of monomer droplet was larger per cubic centimeter of water, the amount of emulgator adsorbed on the surface was increased, the numbers of micelle were reduced per cubic centimeter of water, the rate of nucleation decreased in phase 1, so does the emulsion grains generated, if the initial monomer amount is fixed, the particle size of latex increases. With the increase of stirring intensity, latex particle size also increases in the process of semi-continuous emulsion polymerization are analyzed and verified by M. Zubitur et al, S. Opera. And they further points out that the stirring intensity also affect the nucleation mechanism: under the low intensity, the micellar nucleation and monomer droplet nucleation were presented. And the distribution of particle size is unimodal features. T herefore, in the emulsion polymerization, the diameter of latex particle is related to the number of latex particle, with the increase of stirring intensity, the number of latex particle decreased, the diameter of latex particle increased, vice versa. 2.2 The influence of mixing intensity on the stability of emulsion Emulsion stability is one of the most valuable properties in researches involving emulsions concerned by numerous scientists. The influence of stirring intensity on the emulsion stability is mainly manifested in polymerization stability. During the process of emulsion polymerization, droplet condensation may happen raised by coalescence of latex particles within the emulsion, as a result of the loss of polymer emulsion stability. In other cases, during the emulsion polymerization, the condensate may deposit on the reactor components which are accumulated in a thick layer. This is one kind of phenomenon of gel. These phenomena may make the color of emulsion fade away, delicate feeling disappear, affecting the quality of the product seriously. Stability of high solid content emulsion has two important areas which should be concentrated on to investigate further. On one hand, with an increase in stirring intensity and collision frequency, the emulsion stability which plays an important role in manufacturing products will be decreased. On the other hand, due to the solid content increased inside the emulsion, and the high emulsion viscosity, the emulsion stability in the heat transfer process impact much on the quality of emulsion products. Especially when the mixing intensity is too high, the material internal shearing action is too frequent; the stability of the emulsion polymerization is easy to destroy so finding some methods to keep its stability should be paid special attention to control the mixing intensity. In  pharmaceutics,  hairstyling,  personal hygiene, and  cosmetics, emulsions are frequently used. These are usually oil and water emulsions but dispersed, and which is continuous depends in many cases on the  pharmaceutical formulation. These emulsions may be called  creams,  ointments,  liniments  (balms),  pastes,  films, or  liquids, depending mostly on their oil-to-water ratios, other additives, and their intended  route of administration.[10][11]The first 5 are  topical  dosage forms, and may be used on the surface of the  skin,  transdermally,  ophthalmically,  rectally, or  vaginally. A highly liquid emulsion may also be used  orally, or may be  injected  in some cases.[10]Popular medications occurring in emulsion form include  calamine lotion,  cod liver oil,Polysporin,cortisolcream,Canesten, andFleet. Microemulsions are used to deliver  vaccinesand kill  microbes.[12]Typical emulsions used in these techniques are nanoemulsions of  soybean oil, with particles that are 400-600nm in diameter.[13]The process is not chemical, as with other types of  antimicrobial  treatments, but mechanical. The smaller the droplet the greater the  surface tension  and thus the greater the force required to merge with other  lipids. The oil is emulsified with detergents using a  high-shear mixer  to stabilize the emulsion so, when they encounter the lipids in the  cell membrane  or envelope of  bacteria  or  viruses, they force the lipids to merge with themselves. On a mass scale, in effect this disintegrates the membrane and kills the pathogen. The soybean oil emulsion does not harm normal human cells, or the cells of most other  higher organisms, with the exceptions of  sperm cells  and  blood cells, which are vulnerable to nanoemulsions due to the peculiarities of their membrane structures. For this reason, these nanoemulsions are not currently used  intravenously  (IV). The most effective application of this type of nanoemulsion is for the  disinfection  of  surfaces. Some types of nanoemulsions have been shown to effectively destroy  HIV-1  and  tuberculosis  pathogens on non-porous  surfaces. Objectives 3.3.1 In this experiment, the first objective is to find the relationship of drop size and stirring intensity. In most cases, an increase in stirring intensity will cause an decrease in the size of every droplet inside of the oil-in-water emulsion. In order to keep the stability of the system, a fixed concentration of surfactant (SLES) will be added in each experiment to keep a balance between the forces in both directions. Furthermore, the quantity of SLES used in every system should be kept the same. Besides, the time for this kind of experiments is not enough to carry out all, so only one type of the agitator will be investigated. Therefore, the parameters which can be changed are the speed of the agitator, the oil viscosity and different time intervals. The second objective is to link droplet size to the viscosity of oil. Different concentration and viscosity of oil may render the emulsion system unstable with respect to time, because different oil viscosity means different Reynolds number showing different flow regime that the emulsion is. And thus the other important properties of the emulsion should be affected by the mean viscosity of the oil phase and water phase. The third objective is to investigate the effect of concentration of aqueous phase have on the droplet size. At the same time, the mixing time can influence the size of the oil droplet and its distribution. So that is another meaningful point to investigate. Methodology Viscosity of the oil is: 10, 1000,12500and 30000 cSt. The agitator rotor can run from 10000 to 20000 RPMs for a rotor stator system. Resources requirements Laboratory Safety The author has attended an introduction about health and safety and will obey all rules in the lab. While working with lots of harmful chemicals, I have read the instruction of chemical use which provides some vital information in case of emergency. All the cutters using by stirring operations must be assessed before use. Lab coat, safety glasses and nitrile rubber gloves should be dressed in case of potential danger. I have been working safety in the lab for about half a year in my college and I claim that I have known what I should do for emergent situation and decrease the degree of danger to the least.

Gender and Socialization Essay

The main purpose of this paper is to focus on gender socialization. Human beings that belong to different societies have varied perceptions, opinions, and manners toward socializing with the same or opposite sex. Categorized in the main gender types, male and female are known to react in different ways when given and exposed in the same situation. Regardless of cultural norms or mores of any society in particular, interaction with peers, family, classmates, and other people depend on the male’s and female’s orientation in gender socialization and gender roles. Some concepts attempt to explain the gender issues faced by the two gender types. These attributions of concepts then play an important role in understanding the different societies’ construct of their existing mechanisms of gender roles and expectations including the societies’ gender markers as determinants of sex and gender (SparkNotes, 2008). Gender Socialization Gender and socialization are two different terms that have a relationship with each other. Gender refers to the behavioral characteristics of an individual regarding an individual’s essence of womanhood or manhood, masculinity or femininity, while socialization refers to the social and interpersonal instincts of human in interacting, communicating, and dealing with others. A newborn infant for instance, may be oriented towards its gender by its first experience of socialization after being born. The infant may be more exposed to male socialization rather than female socialization or vice versa which would later on affect the behavior of the infant while growing up. Another example is the way parents choose what the appropriate toy is to be played by their sons and daughters. Usually, parents buy their baby girl a mini-kitchen or ironing set to orient them (however, it is subconscious for the parents’ part) with the future maternal role. For the baby boy’s part, they are usually given toy trucks or tools for various chores in the house for the same underlying purpose. Moreover, upon receiving the presents, the girls usually react more appreciative and smiling than the boys. The essence of gender socialization then, is for the infants to learn the behavior appropriate for their designated sexes (SparkNotes, 2008). Reaction By the time an infant reaches ten months after the day of birth, gender socialization is already executed through the infant’s interaction with the environment, its family members, and caretakers. This is the time when the infant starts to identify him- or herself in either of the two sexes: male or female. Thus, this is also the time for newborn infants to associate the specific gender roles (the attributes and behavior that the culture constructively defines) that are appropriate for their sex and gender. Later in the life of infants, the effects of the previous experience in gender orientation would reflect in their current behavior. Meanwhile, I should say from personal experience that I was mostly given a Barbie doll for Christmas or birthday present. In so doing, I grew up to become a very neat lady who has the taste for fashion and luxury Further, I attribute the idea that I have become a fashionable and finesse lady to my previous hobby of playing, dressing and undressing my Barbie doll (SparkNotes, 2008). Conclusion Gender socialization teaches the infants that would grow as adults the appropriate roles defined by culture and behaviors that are expected of them by the society. Submission to the expectations of the culture and society is important, as every living individual has to interact with others in whatever society he or she belongs to in order to survive and attain a sense of belongingness. Family, peer groups, school, mass media, and some texts play a part in honing this cultured set of beliefs regarding the appropriate roles and expected behaviors for men and women. Men who are accustomed to playing tough games in their childhood result to be future tough guys and women are the opposite. Reference SparkNotes. (2008). Gender socialization.
