2.4.0 Parent functions Essays - Fields Of Mathematics, Mathematics

2.4.0 Parent functions Today we will look at the graphs, domains, and ranges of four parent functions. Parent functions are the base functions, upon which transformations are applied. The line Grade 9 math focussed on the line. In function notation, the basic line is defined by [pic]. |x |y | |-2 |-2 | |-1 |-1 | |0 |0 | |1 |1 | |2 |2 | This line continues forever to the left and right, up and down. [pic] The parabola Grade 10 focussed on the parabola. In function notation, the basic parabola is defined by [pic]. |x |y | |-2 |4 | |-1 |1 | |0 |0 | |1 |1 | |2 |4 | The parabola continues forever to the left and right, continues forever up, but has a minimum y value of zero. [pic] The radical function The radical function is related to the parabola. In function notation, the basic radical function is defined by [pic]. The radical function has serious restrictions on the domain and range. In the real number system, we cannot take the square root of a negative number, and the square root function yields only positive values. |x |y | |0 |0 | |1 |1 | |4 |2 | |9 |3 | |16 |4 | Starting at the origin, the radical function continues right forever and up forever. [pic] The reciprocal function: Rectangular hyperbola. In function notation, the basic reciprocal function is defined by [pic]. The reciprocal function has some interesting properties. Reciprocation does not cause a change in sign. Reciprocating a number close to zero yields a number far from zero, and reciprocating a number far from zero yields a number close to zero. Notice that we can not reciprocate zero, nor can a reciprocation yield zero. |x |y | |-4 |[pic] | |-1 |-1 | |[pic] |-4 | |0 |undefined| |[pic] |4 | |1 |1 | |4 |[pic] | Note the restriction, [pic]. This function continues left and right forever, up and down forever, but x can never be zero, and neither can y. [pic] The graph approaches the axes, but never crosses or touches. This behaviour is call asymptotic. A line that the graph approaches indefinitely is called an asymptote. Determining domain and range from equations This can be done from a sketch, if you know how to sketch. This can be done when using transformations, when you know how to transform. For now, search for problems in the equation (zeroes in the denominator, negatives under square roots, and maxima or minima). Determine the domain and range: Ex1. [pic] No problems here. [pic] Ex2. [pic] No problems for x. The smallest [pic] can be is 0, so the smallest y can be is 3. This can also be identified if you know this is a parabola that opens up with a vertex of [pic]. [pic] Ex3. [pic] [pic] cannot be negative, that is, [pic], so [pic]. The smallest [pic] can be is zero, so the smallest y can be is 2. [pic]

A Brief History of Chinese Opera

A Brief History of Chinese Opera Since the time of the Tang Dynastys Emperor Xuanzong from 712 to 755- who created the first national opera troupe called the Pear Garden- Chinese opera has been one of the most popular forms of entertainment in the country, but it actually started nearly a millennium before in the Yellow River Valley during the Qin Dynasty.   Now, more than a millennium after Xuanzongs death, it is enjoyed by political leaders and commoners alike in many fascinating and innovative ways, and Chinese opera performers are still referred to as Disciples of the Pear Garden, continuing to perform an astonishing 368 different forms of Chinese opera. Early Development Many of the features that characterize modern Chinese opera developed in northern China, particularly in the Shanxi and Gansu Provinces, including the use of certain set characters like Sheng (the man), Dan (the woman), Hua (the painted face) and Chou (the clown). In Yuan Dynasty times- from 1279 to 1368- opera performers began to use the vernacular language of the common people rather than Classical Chinese. During the Ming Dynasty- from 1368 to 1644- and the Qing Dynasty- from 1644 to 1911- the northern traditional singing and drama style from Shanxi was combined with melodies from a southern form of Chinese opera called Kunqu. This form was created in the Wu region, along the Yangtze River. Kunqu Opera revolves around the Kunshan melody, created in the coastal city of Kunshan. Many of the most famous operas that are still performed today are from the Kunqu repertoire, including The Peony Pavilion, The Peach Blossom Fan, and adaptations of the older Romance of the Three Kingdoms and Journey to the West. However, the stories have been rendered into various local dialects, including Mandarin for audiences in Beijing and other northern cities. The acting and singing techniques, as well as costumes and makeup conventions, also owe much to the northern Qinqiang or Shanxi tradition. Hundred Flowers Campaign This rich operatic heritage was almost lost during Chinas dark days in the mid-twentieth century. The Communist regime of the Peoples Republic of China- from 1949 to present- initially encouraged the production and performance of operas old and new. During the Hundred Flowers Campaign in 1956 and 57- in which the authorities under Mao encouraged intellectualism, the arts and even criticism of the government- Chinese opera blossomed anew. However, the Hundred Flowers Campaign may have been a trap. Beginning in July of 1957, the intellectuals and artists who had put themselves forward during Hundred Flowers period were purged. By December of that same year, a stunning 300,000 people had been  labeled  rightists and were subjected to punishments from informal criticism to internment in labor camps or even execution. This was a preview of the horrors of the Cultural Revolution of 1966 through 1976, which would imperil the very existence of Chinese opera and other traditional arts. Cultural Revolution The Cultural Revolution was the regimes attempt to destroy old ways of thinking by outlawing such traditions as fortune telling, paper-making, traditional Chinese dress and the study of classic literature and arts. An attack on one Beijing opera piece and its composer signaled the start of the Cultural Revolution. In 1960, Maos government had commissioned Professor Wu Han to write an opera about Hai Rui, a minister of the Ming Dynasty who was fired for criticizing the Emperor to his face. Audiences saw the play as a critique of the Emperor- and thus Mao- rather than of Hai Rui representing disgraced Minister of Defense Peng Dehuai. In reaction, Mao performed an about-face in 1965, publishing harsh criticism of the opera and of composer Wu Han, who was eventually fired. This was the opening salvo of the Cultural Revolution. For the next decade, opera troupes were disbanded, other composers and scriptwriters were purged and performances were banned. Until the fall of the Gang of Four in 1976, only eight model operas were allowed. These model operas were personally vetted by Madame Jiang Qing and were entirely politically innocuous. In essence, Chinese opera was dead. Modern Chinese Opera After 1976, Beijing opera and the other forms were revived, and once more placed within the national repertoire. Older performers who had survived the purges were allowed to pass on their knowledge to new students again. Traditional operas have been freely performed since 1976, though some newer works have been censored and new composers criticized as the political winds have shifted over the intervening decades. Chinese opera makeup is particularly fascinating and rich in meaning. A character with mostly red makeup or a red mask is brave and loyal. Black symbolizes boldness and impartiality. Yellow denotes ambition, while pink stands for sophistication and cool-headedness. Characters with primarily blue faces are fierce and far-seeing, while green faces show wild and impulsive behaviors. Those with white faces are treacherous and cunning- the villains of the show. Finally, an actor with only a small section of makeup in the center of the face, connecting the eyes and nose, is a clown. This is called xiaohualian, or the little  painted  face. Today, more than thirty forms of Chinese opera continue to be performed regularly throughout the country. Some of the most prominent of which are the Peking opera of Beijing, Huju opera of Shanghai, the Qinqiang of Shanxi, and Cantonese opera.   Beijing (Peking) Opera The dramatic art form known as Beijing opera- or Peking opera- has been a staple of Chinese entertainment for more than two centuries. It was founded in  1790 when the Four Great Anhui Troupes went to Beijing to perform for the Imperial Court. Some 40 years later, well-known opera troupes from Hubei joined the Anhui performers, melding their regional styles. Both the Hubei and Anhui opera troupes used two primary melodies adapted from the Shanxi musical tradition: Xipi and Erhuang. From this amalgam of local styles, the new Peking or Beijing opera developed. Today, Beijing Opera is considered  Chinas  national art form. Beijing Opera is famous for convoluted plots, vivid makeup, beautiful costumes and sets and the unique vocal style used by performers. Many of the 1,000 plots- perhaps not surprisingly- revolve around political and military strife, rather than romance. The basic stories are often hundreds or even thousands of years old involving historic and even supernatural beings.   Many fans of Beijing Opera are worried about the fate of this art form. The traditional plays make reference to many facts of pre-Cultural Revolution  life and history that are unfamiliar to young people. Furthermore, many of the stylized movements have particular meanings that can be lost on uninitiated audiences. Most troubling of all, operas must now compete with films, TV shows, computer games, and the internet for attention. The Chinese government is using grants and contests to encourage young artists to participate in Beijing Opera. Shanghai (Huju) Opera Shanghai opera (Huju) originated at about the same time as Beijing opera, around 200 years ago. However, the Shanghai version of opera is based on local folk-songs of the Huangpu River region rather than deriving from Anhui and Shanxi.  Huju  is performed in the Shanghainese dialect of Wu Chinese, which is not mutually intelligible with  Mandarin. In other words, a person from Beijing would not understand the lyrics of a  Huju  piece. Due to the relatively recent nature of the stories and songs that make up  Huju, the costumes and makeup are comparatively simple and modern. Shanghai opera performers wear costumes that resemble the street clothing of ordinary people from the pre-communist era. Their makeup is not much more elaborate than that worn by western stage actors, in stark contrast to the heavy and significant grease-paint used in the other Chinese Opera forms. Huju  had its heyday in the 1920s and 1930s. Many of the stories and songs of the Shanghai region show a definite western influence. This is not surprising, given that the major European powers maintained trading concessions and consular offices in the thriving port city, prior to World War II. Like many of the other regional opera styles,  Huju  is in danger of disappearing forever. Few young actors take up the art form since there is much greater fame and fortune to be had in movies, TV, or even Beijing Opera. Unlike Beijing Opera, which is now considered a national art form, Shanghai Opera is performed in a local dialect and thus does not translate well to other provinces. Nevertheless, the city of Shanghai has millions of residents, with tens of millions more in the near vicinity. If a concerted effort is made to introduce younger audiences to this interesting art form,  Huju  may survive to delight theater-goers for centuries to come. Shanxi Opera (Qinqiang) Most forms of Chinese opera owe their singing and acting styles, some of their melodies, and their plot-lines to the musically fertile Shanxi province, with its thousand-year-old Qinqiang  or  Luantan  folk melodies. This ancient form of art first appeared in the  Yellow River  Valley during the  Qin Dynasty  from B.C. 221 to 206 and was popularized at the Imperial Court at modern-day  Xian during the  Tang Era, which spanned from 618 to 907 A.D. The repertoire and symbolic movements continued to develop in Shanxi Province throughout the  Yuan Era  (1271-1368) and the Ming Era (1368-1644). During the Qing Dynasty (1644-1911), Shanxi Opera was introduced to the court at Beijing. The Imperial audiences so enjoyed Shanxi singing that the form was incorporated into Beijing Opera, which is now a national artistic style. At one time, the repertoire of Qinqiang included over 10,000 operas; today, only about 4,700 of them are remembered. The  arias  in Qinqiang Opera are divided into two types:  huan  yin, or joyous tune, and  ku  yin, or sorrowful tune. Plots in Shanxi Opera often deal with fighting oppression, wars against the northern barbarians, and issues of loyalty. Some Shanxi Opera productions include special effects such as fire-breathing or acrobatic twirling, in addition to the standard operatic acting and singing. Cantonese Opera Cantonese Opera, based in southern China and overseas ethnic Chinese communities, is a very formalized operatic form that emphasizes gymnastic and martial arts skills. This form of Chinese Opera predominates in Guangdong,  Hong Kong, Macau,  Singapore,  Malaysia, and in Chinese-influenced areas in western countries. Cantonese Opera was first performed during the reign of the Ming Dynasty Jiajing Emperor from 152 to 1567. Originally based on the older forms of Chinese Opera, Cantonese Opera began to add local folk melodies, Cantonese instrumentation, and eventually even Western popular tunes. In addition to traditional Chinese instruments such as the  pipa,  erhu, and percussion, modern Cantonese Opera productions may include such Western instruments as the violin, cello, or even saxophone. Two different types of plays make up the Cantonese Opera repertoire- Mo, meaning martial arts, and  Mun, or intellectual- wherein the melodies are entirely secondary to the lyrics.  Mo performances are fast-paced, involving stories of warfare,  bravery  and betrayal. The actors often carry weapons as props, and the elaborate costumes may be as heavy as actual armor. Mun, on the other hand, tends to be a slower, more polite art form. The actors use their vocal tones, facial expressions, and long flowing water sleeves to express complex emotions. Most of the Mun stories are romances, morality tales, ghost stories, or famous Chinese classic tales or myths. One notable feature of Cantonese Opera is the makeup. It is among the most elaborate makeup systems in all of Chinese Opera, with different shades of color and shapes, particularly on the forehead, indicating the mental state, trustworthiness, and physical health of the characters. For example, sickly characters have a thin red line drawn between the eyebrows, while comic or clownish characters have a large white spot  on  the bridge of the nose. Some Cantonese Operas also involve actors in open face makeup, which is so intricate and complicated that it resembles a painted mask more than a living face. Today, Hong Kong is at the center of efforts to keep Cantonese Opera alive and thriving. The Hong Kong Academy for the Performing Arts offers two-year degrees in Cantonese Opera performance, and the Arts Development Council sponsors opera classes for the citys children. Through such concerted effort, this unique and intricate form of Chinese Opera may continue to find an audience for decades to come.

Many software systems employ graphical user interface. What sorts of Essay

Many software systems employ graphical user interface. What sorts of user interface were employed before GUIs was available How - Essay Example On the other hand, liveware refers to the users i.e. human beings, who operate the systems by issuing commands to be executed by the system (Anderson 2001). However, for these users to be able to input data and commands, which instruct the system to perform various actions, there must be a way through which they can interact with the computer, which is commonly referred to as human computer interface (HCI) (Stephenson 2001). For example, if a user wants to open an already existing document, he must issue an ‘open’ command to the system through the computer interface available in his system. Currently, there are two major HCI i.e. command line (CLI) and the graphical user interfaces (GUI). Command line interfaces were the most widely used before technological advances in programming resulted to the designing of window based operating systems, which enabled users to interact with their computers through GUI. In a command driven interface, the user uses the keyboard to type commands, which are acceptable to the computer, after which the results are displayed on the screen in form of text. This type of interface came in to use in the early 1950s, an invention which was motivated by the introduction of teletypewriters, which demanded instant display of results (Stephenson 2001). Before this, batch interfaces were used, which are considered to have been non-interactive as they only required the user to input all the data in order for processing to begin, after which there was no opportunity for inputting more data until after all the data was processed and output was given (Stephenson 2001). The disc operating system (DOS) is one of the environments that make use of the command line interface. In order to be able to operate such an interface, it is a must for one to have excellent skills and understanding of the various internal and external commands, which follow predetermined syntaxes (Gookin 2004). For example, if a user intends to view files located in the hard drive i.e. the hard disk, he would have to type a command, which would order the system to display all the files as per the user’s request. The syntax in such a context would appear as follows; c:\dir after which you press enter to display the contents. To access a removable storage media named drive E, one has to type a special command designed for that purpose. This would appear as follows; c:\e: then press enter. C:\ in this case is the root directory, while e: is the destination drive. This implies that command driven interface is tedious to use as one must follow the exact syntax and path in order to get results, which may be the reason why it is widely used by programmers and other IT specialists, who are well conversant with the commands (Gookin 2004). The graphical user interface as opposed to command line interface uses images, which are event driven. This means that once the user clicks on the image, a predetermined action is triggered and as such, click ing becomes a command executor in contrary to CLI where one had to type a specific command on a command prompt (Anderson 2001). However, it is important to note that GUI enables the user to use both the keyboard and the mouse to execute commands. Images in this context are for example; radio buttons, windows, icons, menus among others, which are designed in a

Utilitarianism and Deontology Assignment Example | Topics and Well Written Essays - 750 words

Utilitarianism and Deontology - Assignment Example There are many different philosophical perspectives that one could apply to the issue of human cloning; it is the utilitarian and deontological perspective that offer two interesting comparative views. Human cloning has dominated science fiction for decades with scenarios revealing how the practice could go terribly wrong. Ethical debates have proposed many other unique issues with cloning; everything from the development of unforeseen genetic flaws, to the devaluation of life, to whether, or not, a cloned being will have rights and even a soul. (McGee) However, it is the incredible potential of medical â€Å"miracles† that cloning might allow, in all its forms, which includes, ending infertility, eradicating genetic diseases, curing illnesses, replacing damaged organs, and last but not least, the ability to create life as they see fit, that continues to lure supporters. The potential positives and plausible negatives of human cloning are not an easy controversy to weigh. Utilitarianism essentially takes an ultimate stand of; do the ends justify the means? The philosophy cares less about how you accomplish something as long as the overall outcome leads to the greatest amount of overall good and happiness. (Moreland 1) While deontology considers less the outcomes and more about the intention behind doing it. The moral intent is more important in deciding whether something is good or bad, or right or wrong, has greater than the outcomes and results. The ideology embraces the â€Å"Categorical Imperatives,† which include a "universality" within the principles, all humans are rational agents, and must be treated as such.

Philosophy Contemporary Moral Problems - Essay Example In that context a sense of duty gains preponderance over claim over rights in the sense that it raises the issue of propositions related to duties (Tuck 5). Any attempt to elaborate on the meaning of a term like ‘rights’, is dependant to a great extent on the enjoining theories and since times immemorial, varied theories have played a pivotal role in the determination of the meaning and the spirit of the term ‘rights’ (Tuck 8). This raises many questions pertaining to the meaning of ‘rights’, as to whether rights are something whose application and expression could be directly controlled by its possessors, or is it the moral and political duty of the public institutions and laws to make way for a hassle free extension of rights (Tuck 8)? Thus, the natural rights theory pertaining to the basic freedoms and rights which should be accessible to all individuals is not that simplistic and straightforward in its philosophical and political scope. Before delving on a philosophical delineation of the concept of natural rights and the successive developments and the emergence of varied classifications, it will be really pragmatic to delve on the notion of natural rights in a simplistic context. Natural rights are the rights that tend to be universal in their scope and application and that are readily accessible to all the individuals simply by the virtue of their being human. Natural rights include within their ambit a range of rights affiliated to civil, cultural, political, social, and economic rights. The theory of natural rights is quintessentially based on the notion of human dignity and worth. In a historical perspective, the notion of natural rights could be traced back to the tablet of Hammurabi. Though the codifications of Hammurabi tended to protect the individuals from arbitrary persecution and exploitation, they

Effect of Formic Acid Supplementation on Brioler Chickens

Effect of Formic Acid Supplementation on Brioler Chickens Effect of Formic Acid supplementation on some biochemical parameters of broiler chickens Murad K. Al-Fadhli*, Nora Q. Abbas *, Mustafa J. Jalil* * Ministry of Science and Technology, Animal and Fish Research Center Abstract: The aim of this study was to evaluate the effect of adding different concentrations of the organic furmaric acid to the drinking water on some biochemical parameters of broiler chickens aged between 21 and 42 days. Organic formic acid was added to the drinking water in the following concentration (0.1%, 0.2%, and 0.3%) represented the treatment group (T1, T2 and T3) respectively. In the control group (T4), the drinking water was free of formic acids. Blood samples were collected at 21 and 42 days of age. At 21 days of age, data indicated that the first treatment group (T1) showed a significant increase (P†°Ã‚ ¤0.05) in serum total protein and albumin and significant decrease (P†°Ã‚ ¤0.05) in each of serum cholesterol, triglycerides and serum glucose. The second treatment group (T2) was also showed a significant increase (P†°Ã‚ ¤0.05) in serum total protein and albumin, in addition to serum cholesterol but it showed significant decrease (P†°Ã‚ ¤0.05) in both serum triglycerides and serum glucose. Whereas the third treatment group (T3) was showed a significant increase (P†°Ã‚ ¤0.05) in each of serum total protein, albumin, cholesterol, and serum triglycerides, but it was showed non-significant differences (P†°Ã‚ ¥0.05) in serum glucose concentration. The result of the blood samples that was collected at 42 days of age indicated a presence of a significant decrease (P†°Ã‚ ¤0.05) in serum total protein level, non-significant differences (P†°Ã‚ ¥0.05) in both of albumin and cholesterol level, but it was showed a significant increase (P†°Ã‚ ¤0.05) in both serum triglycerides and glucose levels in the first treatment group (T1). The second treatment group (T2) was showed a significant increase (P†°Ã‚ ¤0.05) in each of serum total protein, triglycerides and serum glucose levels, but it was showed non-significant differences (P†°Ã‚ ¥0.05) in serum albumin level and non-significant decrease (P†°Ã‚ ¥0.05) in seru m glucose levels. The result from the third treatment group (T3) indicated non-significant differences (P†°Ã‚ ¥0.05) in each of serum total protein, albumin, cholesterol levels, and non-significant decrease in serum glucose levels. Indicated results showing the importance of adding organic formic acid to the drinking water in the improvement of some physiological traits of broiler chickens. Key words: organic acids, formic acid, physiological traits, broiler chickens. Introduction: Broiler chicken meat is considered one of the most important sources of animal protein and the poultry production rate was 25% of the total global production of meat (1). Broiler chicken meat is characterized by their high nutritional value as it is rich in the essential elements in addition to its easy digestion (2). Poultry production has consistently in recent years to find the ways to improve the growth rates in order to obtain the highest conversion efficiency of food as well as reduction of the negative effects of the diseases that lead to heavy economic losses. One of the most important ways to control the negative effect of the diseases was the introduction of the antibiotics in the poultry production (3). However, use of these antibiotics on a large scale has led to the development of the bacterial resistance to antibiotics. In addition to that, use of antibiotics lead to cumulative harmful effect on poultry meat as it alters the bacterial environment and leading to weakenin g performance of poultry production (4). Therefore, the research tries to find an alternative to antibiotics to control the negative effect of the diseases and among these alternatives to antibiotics was the use of organic acids and the addition of probiotic to poultry feeds (5). Organic acids are weak acids that are commonly found in fruit juices and fermented foods and that are added to foods as preservative agents (6). Organic acids have been used for decades in feed preservation, for protecting feed from microbial and fungal destruction or to increase the preservation effect of fermented feed. Organic acids have increasingly and successfully been supplemented in feed in broiler production. The way of action of organic acids seems to be related to a reduction of pH in the upper intestinal tract, interfering with the growth of undesirable bacteria and modifying the intestinal flora (7). The aim of the present study was to evaluate the effect of adding different concentrations of t he organic formic acid to the drinking water on some physiological traits of broiler chickens. Materials and Methods: This study was conducted in the chicken field of the poultry section in the Center of Animal Resources and Fisheries Agricultural Research Directorate Ministry of Science and Technology, which included the field and laboratory study to examine the effect of adding formic acid in the drinking water on the productive performance of broiler chickens. 84 mixed sexes broiler chickens (Rose Type), one-day old, were used for the experiment. These broiler chickens were distributed randomly inside a closed room into four groups as the following: First group (Treatment 1): The Drinking water treated with 0.1 % formic acid. Second group (Treatment 2): The Drinking water treated with 0.2 % formic acid. Third group (Treatment 3): The Drinking water treated with 0.3 % formic acid. Fourth group (Control group): Free of formic acid. Each group was further sub-divided into three replicates of 7 birds per replicate. A photo period of 24 hours day was maintained since the start of the experiment and until the end of the sixth week by using electric lamps. The ingredient and the chemical composition of the diets presented in Table 1. They were analyzed using N.R.C (1994) procedure. Feed and water were provided ad libitum during the experiment. Table 1: The ingredient and the chemical composition of the diets Ingredients Percentage composition Yellow corn 43 wheat 12 Barley 9 Soybean meal 20 Animal protein concentrate 12 Oil 3 Limestone 0.7 Salt 0.3 Total 100% Calculated levels Crude protein (%) 21.14 ME (Kcal/kg) 3032 Protein-energy ratios 143 Lysine (%) 0.82 Methionine + Cystine (%) 0.73 Crude fiber (%) 2.16 Blood samples were collected at 21 and 42 days of age from the wing vein and centrifuged at 3000 rpm for 5 minutes by using Hettich centrifuge to separate the serum samples and the obtained sera were aspirated into sterile vials and kept in deep freezer (-20 °C) for the later analysis of the serum biochemical parameters that include the serum total protein, albumin, cholesterol, triglycerides and glucose and these analysis was estimated by using the Vegasys chemical analyzer device (AMS Co., Italy). Statistical analysis was performed with statistical program Statistacal Analysis System (SAS) (2001). Means were compared by the Duncans multiple range test at the level of 5% probability (1955). Results and Discussion: The results illustrated in Table (2) indicate the serum biochemical analysis of the broiler chickens at 21 days of age. These data showed a significant increase (P†°Ã‚ ¤0.05) in the concentration of serum total protein and albumin in the treatment groups (T1, T2 and T3) in compartment with the control group (T4). Serum cholesterol concentration was significantly increased (P†°Ã‚ ¤0.05) in the treatment groups (T2 and T3) while it was significantly decreased (P†°Ã‚ ¤0.05) in the treatment group (T1) in compartment with control group (T4). Serum triglycerides concentration showed a significant decrease (P†°Ã‚ ¤0.05) in the treatment groups (T1 and T2), while it was significantly increased (P†°Ã‚ ¤0.05) in the treatment group (T3) in compartment with control group (T4). Serum glucose concentration was also significantly decreased (P†°Ã‚ ¤0.05) in the treatment groups (T1 and T2), but it was non- significantly increased (P†°Ã‚ ¥0.05) in the treatment gr oup (T3) in compartment with control group (T4).

In this study, the addition of formic acid to the diet resulted in significant decrease in the total cholesterol. The results obtained from the present study are in agreement with the results obtained by (El-Kerawy 1996) (9). The significant reduction in serum cholesterol could be attributed to the probiotic secretion of organic acid that stimulate the probiotic bacteria Lactobacillus acidophilus to reduces the cholesterol in the blood by deconjugating bile salts in the intestine, thereby preventing them from acting as precursors in cholesterol synthesis (Abdulrahim et al., 1996) (10). In the present study, the addition of formic acid to diets was significantly decreased the serum triglycer ides concentration and this decline may be due to secretion of the inuline and the inulin in turn has an inhibitor effect on the triglycerides synthesis processes (11). This experiment was showed a significant age-related difference either in the levels of the serum total protein, albumin and serum glucose. These age-related changes have also been observed in broilers chickens reported by (Sribhen C. et al, 2003) (12). The effect of organic acid supplementation on protein metabolism may be related to improvement of intestinal amino-acids absorption in acidic conditions that consequently enhances protein synthesis (13). This study concluded that the use of organic formic acid had a role in the improvement of some physiological traits in broiler chickens. References:   Ã‚   F.O.A, Statistics and meat. 2000 Rafh M.T.

Gender and Society :: Gender Society Sexism Essays Papers

Society has stamped an image into the minds of people of how the role of each gender should be played out. There are two recognized types of gender, a man and a woman, however there are many types of gender roles a man or a woman may assume or be placed into by society. The ideas of how one should act and behave are often times ascribed by their gender by society, but these ascribed statuses and roles are sometimes un-welcomed, and people will assume who they want to be as individuals by going against the stereotypes set forth by society. This paper will examine these roles in terms of how society sees men and women stereotypically, and how men and women view themselves and each other in terms of stereotypes that are typically ascribed, as well as their own opinions with a survey administered to ten individuals. What I hope to prove is that despite stereotypes playing a predominant role within our society, and thus influencing what people believe about each other in terms of their same and opposite genders, people within our society are able to go against these ascribed stereotypes and be who they want and it be okay. Through use of the survey and my own personal history dealing with gender stereotyping I think I can give a clear idea as to how stereotypes envelope our society, and how people and breaking free from those stereotypes to be more individualistic. The differences between women and men are not solely biological. Our society’s culture has established a set of unwritten cultural laws of how each gender should act, or in other words society has ascribed a stereotype. Men’s gender identity has been one of masculinity, and masculinity is defined as referring to a man or things described as manly. What does manly mean though? Is a male manly if he is â€Å"Mr. Fix-it†, or the jock, or if he sits on the couch on Sunday watching football? This latter statement is a stereotype of men, that has been around for decades, and is current as well, but starting with the 1960’s a man’s role started to change, despite the stereotype not changing to accommodate it. For the past 40 years one can see how men have taken on roles stereotypically ascribed to women, such roles including being the â€Å"stay-at-home mom†, which we can find an excellent example of in the 1980’s film â€Å"Mr.
