The Effects Of HIV Mutations On The Immune System Science C.J. Stimson

The Effects of HIV Mutations on the Immune System Science C.J. Stimson INTRODUCTION The topic of this paper is the human immunodeficiency virus, HIV, and whether or not mutations undergone by the virus allow it to survive in the immune system. The cost of treating all persons with AIDS in 1993 in the United States was $7.8 billion, and it is estimated that 20,000 new cases of AIDS are reported every 3 months to the CDC. This question dealing with how HIV survives in the immune system is of critical importance, not only in the search for a cure for the virus and its inevitable syndrome, AIDS (Acquired Immunodeficiency Syndrome), but also so that over 500,000 Americans already infected with the virus could be saved. This is possible because if we know that HIV survives through mutations then we might be able to come up with a type of drug to retard these mutations allowing the immune system time to expunge it before the onset of AIDS. BACKGROUND In order to be able to fully comprehend and analyze this question we must first ascertain what HIV is, how the body attempts to counter the effects of viruses in general, and how HIV infects the body. Definition HIV is the virus that causes AIDS. HIV is classified as a RNA Retrovirus. A retrovirus uses RNA templates to produce DNA. For example, within the core of HIV is a double molecule of ribonucleic acid, RNA. When the virus invades a cell, this genetic material is replicated in the form of DNA . But, in order to do so, HIV must first be able to produce a particular enzyme that can construct a DNA molecule using an RNA template. This enzyme, called RNA-directed DNA polymerase, is also referred to as reverse transcriptase because it reverses the normal cellular process of transcription. The DNA molecules produced by reverse transcription are then inserted into the genetic material of the host cell, where they are co-replicated with the host's chromosomes; they are thereby distributed to all daughte r cells during subsequent cell divisions. Then in one or more of these daughter cells, the virus produces RNA copies of its genetic material. These new HIV clones become covered with protein coats and leave the cell to find other host cells where they can repeat the life cycle. The Body Fights Back As viruses begin to invade the body, a few are consumed by macrophages, which seize their antigens and display them on their own surfaces. Among millions of helper T cells circulating in the bloodstream, a select few are programmed to ?read? that antigen. Binding the macrophage, the T cell becomes activated. Once activated, helper T cells begin to multiply. They then stimulate the multiplication of those few killer T cells and B cells that are sensitive to the invading viruses. As the number of B cells increases, helper T cells signal them to start producing antibodies. Meanwhile, some of the viruses have entered cells of the body - the only place they are able to replicate. Killer T cells will sacrifice these cells by chemically puncturing their membranes, letting the contents spill out, thus disrupting the viral replication cycle. Antibodies then neutralize the viruses by binding directly to their surfaces, preventing them from attacking other cells. Additionally, they precipitate chemical reactions that actually destroy the infected cells. As the infection is contained, suppresser T cells halt the entire range of immune responses, preventing them from spiraling out of control. Memory T and B cells are left in the blood and lymphatic system, ready to move quickly should the same virus once again invade the body. HIV's Life Cycle In the initial stage of HIV infection, the virus colonizes helper T cells, specifically CD4+ cells, and macrophages, while replicating itself relatively unnoticed. As the amount of the virus soars, the number of helper cells falls; macrophages die as well. The infected T cells perish as thousands of new viral particles erupt from t he cell membrane. Soon, though, cytotoxic T and B lymphocytes kill many virus-infected cells and viral particles. These effects limit viral growth and allow the body an opportunity to temporarily restore its supply of helper cells to The Effects Of HIV Mutations On The Immune System Science C.J.

Profile of Richard Speck, Serial Killer

Profile of Richard Speck, Serial Killer The words Born to Raise Hell were tattooed on the arm of the tall, pocked-faced man with a southern drawl who entered a nursing students dormitory on a warm July night in 1966. Once inside he committed a series of crimes that shocked America and sent Chicago authorities on a massive manhunt for a madman who they soon identified as Richard Speck. This is a profile of the man, his life, and his crimes, both during his life and after his death. Childhood Years Speck was born December 6, 1941, in Kirkwood, Illinois. When he was six, his father died. His mother remarried, and the family moved to Dallas, TX. Before marrying her new husband, she raised the family under strict religious rules including the abstinence of alcohol. After her marriage, her attitude changed. Her new husband had violent drunken episodes, often making young Richard the victim of his abuse. Speck grew up to become a poor student and juvenile delinquent prone to violent behavior. Spousal Rape and Abuse At age 20, Speck married 15-year-old Shirley Malone and fathered a child. Specks violent nature extended into the marriage and he regularly abused his wife and her mother. The abuse included spousal rape at knifepoint, often several times a day. He worked as a part-time garbage man and petty thief but his criminal activity escalated, and in 1965 he held a woman at knifepoint and attempted to rob her. He was caught and sentenced to jail for 15 months. By 1966 his marriage was over. A Walking Time Bomb After prison Speck moved to his sisters home in Chicago to avoid being questioned by authorities for various crimes in which he was suspected of being involved. He tried to find work as a merchant seaman but spent most of his time hanging in bars drinking and bragging about past crimes. He moved in and out of sisters home, opting to rent rooms in sleazy hotels when possible. Speck, tall and unattractive, was a drug addict, alcoholic, and jobless, with a violent streak waiting to be unleashed. Speck Meets the Chicago Police Department On April 13, 1966, Mary Kay Pierce was found dead behind the bar where she worked. Speck was questioned by police about the murder but feigned illness, on promising to return to answer questions on April 19. When he didnt show, the police went to the Christy Hotel where he was living. Speck was gone, but police searched his room and found items from local burglaries including jewelry belonging to 65-year-old Mrs. Virgil Harris, who had been held at knifepoint, robbed, and raped that same month.​ On the Run Speck, on the run, tried to get work on a barge and was registered at the National Maritime Union Hall. Directly across the street from the union hall was student housing for nursing students working at the South Chicago Community Hospital. On the evening of July 13, 1966, Speck had several drinks at a bar under the rooming house where he was staying. Around 10:30 p.m. he walked the 30-minute walk to the nurses townhouse, entered through a screen door and rounded up the nurses inside. The Crime At first, Speck reassured the young women that all he wanted was money. Then with a gun and a knife, he scared the girls into submission and got them all into one bedroom. He cut strips of bed sheets and bound each of them and began removing one after another to other parts of the townhouse where he murdered them. Two nurses were murdered as they returned home and walked into the mayhem. The girls waiting their turn to die tried to hide under beds but Speck found them all but one. The Victims Pamela Wilkening - Gagged, stabbed through the heart.Gloria Davy - Raped, sexually brutalized, strangled.Suzanne Farris - Stabbed 18 times and strangled.Mary Ann Jordan - Stabbed in the chest, neck, and eye.Nina Schmale - Stabbed in her neck and suffocated.Patricia Matusek - punched resulting in a ruptured liver and strangled.Valentina Paison - Her throat was cut.Merlita Gargullo - Stabbed and strangled. The One Who Survived Corazon Amurao slid under the bed and pushed herself tight against the wall. She heard Speck return to the room. Paralyzed with fear she heard him rape Gloria Davy on the bed above. He then left the room, and Cora knew she was next. She waited hours, fearing his return at any moment. The house was silent. Finally, in the early morning, she pulled herself from underneath the bed and climbed out the window, where she huddled in fear, crying until help came. The Investigation Cora Amurao provided investigators with a description of the killer. They knew he was tall, maybe six feet in height, blond, and had a deep southern accent. Specks appearance and unique accent made it difficult for him to blend into a Chicago crowd. People who encountered him remembered him. This assisted investigators to eventually capturing him. Speck Attempts Suicide Speck found a low-rent hotel that had cell-like rooms for the patrons who were mostly drunks, drug addicts, or insane. When he discovered police knew his identity – his face and name appeared across the front page of the newspapers – he decided to take his life by cutting his wrists and inner elbow with jagged glass. He was found and taken to the hospital. It was there that first-year-resident, Leroy Smith, recognized Speck and called the police. The End of Richard Speck Cora Amurao, dressed as a nurse, entered Specks hospital room and identified him to police as the killer. He was arrested and stood trial for murdering the eight nurses. Speck was found guilty and sentenced to death. The Supreme Court ruled against capital punishment, and his sentence was changed to 50 to 100 years in prison. Speck Dies Speck, age 49, died from a heart attack in prison on December 5, 1991. When he died, he was fat, bloated, with ash-white pockmarked skin and hormone-injected breasts. No family members claimed his remains; he was cremated, and his ashes were thrown in an undisclosed place. Beyond the Grave In May 1996, a videotape sent to news anchor Bill Curtis showed Speck with female-like breasts having sex with a fellow prisoner. He could be seen doing what appeared to be cocaine, and in an interview-like discussion, he answered questions about the murders of the nurses. Speck said he felt nothing about murdering them and that it was just not their night. His old bragging habits returned as he described prison life and added, If they only knew how much fun I was having, theyd turn me loose. Source:The Crime of the Century by Dennis L.

Inclusive Education and SEN Essay Example | Topics and Well Written Essays - 3000 words

Inclusive Education and SEN - Essay Example In this essay, l will demonstrate an understanding, of implications of including, children with additional needs in the mainstream school setting. I will consider the different models of disability. I will also demonstrate my ability to collect evidence about a child’s needs from a variety of sources and use the evidence to inform practice. Show my understanding of individual educational Plan (I.E.P), and how it can be developed to support inclusion. I will then evaluate the use of appropriate resources and strategies to support the child. Implications of including children with additional needs in a mainstream setting: The concept of inclusive education is as a result of parents and disabled people putting pressure on successive governments to change the education system, so as to allow all children to have a fair and equal access to education (Tassoni 2003, p.11). Including children with, special needs within the mainstream school has got its own implications. One of these implications will be ensuring, whether the layout and resources are appropriate, and inclusive. The environment plays a key role in supporting and extending children’s development and learning (Early year’s foundation Stage (E.Y.F.S, 2008). For example, having a child, who uses a wheelchair, will not be able to move in and out of the building independently without ramps. Although the issue of inclusive education is a highly debated issue, it has garnered unanimous support internationally, which is apparent from the fact that governments worldwide, have introduced policy initiatives whereby the cause of including st udents with special needs in regular schools has been supported, and treated as a human rights issue (OECD Publishing, 19992). This entails that schools today, are required to have trained staff who is specialized in supporting students with SEN (Special Education Needs) for instance, those diagnosed with autism. This is because, the educational needs of an autistic child is starkly different than those of a regular child, and hence special courses are required to be designed, developed and implemented to meet the special needs of such children. The SEN code of practice makes it the responsibilities of schools and early years setting to be able to identify children’s difficulties in terms of ‘graduate approach’, to the identification, assessment and recording of any difficulties these children may face (Linda, Carrie and Jane, 2005.p.132). The teachers, needs to adapt a positive attitude towards children with special needs, and ensure that there is no barrier of access. They need to ensure that, they are taking into account, views of the child, parents, colleagues and other professionals into consideration to meet the child’s needs, and adapt change to the environment accordingly. The attitudes of all adults who work in the schools, need to be such that, they are working to encourage the participation of all children in both academic and social life of the school (Halliwell 2003, p.20). Within my setting layout of equipment, is at every child’s level, this means, they can choose toys independently to play with, without any hindrance. And will playa vital role towards achieving independence. The school will need to make sure that; there are appropriate policies and procedures in place in conjunction with the ‘code of practice’. These policies will be ensuring that, children with special needs are given, full access to education, as any ordinary child. The

Business strategy in Chinese restaurant Assignment - 1

Business strategy in Chinese restaurant - Assignment Example The purpose of this report is to explore the marketing strategies of Hai Di Lao hot pot by applying the PESTEL and SWOT framework. The strategic options for expansion of the restaurant are discussed in this report and finally the recommendations are suggested. Political: The Chinese government has been following liberalization policies and this includes a drive of opening foreign based fast food chains in the country. Since 2007, the government have banned all the unlicensed food suppliers. This implies that the restaurant owners have to be highly careful in terms of procurement of food from suppliers. The Chinese government’s policy on food safety is paramount. Economic: China is one of the fastest growing markets among the emerging market economies with an average rate of growth of 9.10 % from 1990 to 2014 (Trading Economics, 2014). The growth of the Chinese economy has been coupled with the growth of disposable income of middle class (Wang, 2012). The average rate of per capita GDP of China is estimated to be about $ 2611 dollars (World Bank, 2014). According to statistics, the fast food restaurant in China is expected to grow by 6% in terms of value sales (Euromonitor International, 2014). Social: Based on social taste and preferences, Chinese fast food market can be differentiated on the basis of domestic fast food industry and foreign fast food industry (Deloitte, 2012). Though, the consumers are acquiring a taste of foreign fast foods yet the domestic Chinese fast food is very popular representing 70% of market share (Research and Markets, 2011). Technological: Technological elements like using Electronic Funds Transfer at Point of Sale (EFTPOS) and advanced equipments in the kitchen reduce cost of production of the company. Using social media marketing and using internet technology to manage inventory can also help companies reduce their costs. Legal: Legislations for restaurant industry in China is

Gender roles Essay Example for Free

Gender roles Essay Well, the topic of gender roles is a ripe one. While there is no specific outline providing benchmarks to use in classifying a person’s gender, a number of factors come into play in helping define one’s gender. One of the factors is cultural prescription as provided for by a person’s social group. A man is a man or a woman a woman depending on how the social group they belong to label or socializes them. But one should remember here that genitalia alone do not determine a person’s gender. While one’s sex is determined by one’s biology, both biology and culture (nature and nurture) determine their gender. There are different roles for different genders. Gender is more of culturally than biologically determined. In fact, a person could be born with male genitalia but be of female gender or vice versa. Differences exist between the male and female genders for instance; men are braver than women and women more emotional than men. Women like being protected while men like to protect. Also, men want to pursue a woman for relationship while women want to be pursued. The differences between the genders emanate from differences in sexes culture, religion among others. Some of the similarities include: both are jealous, self-centered and want to mend the other to live up to their own standards. Again, both genders converge in their need for recognition and love. These among other differences and similarities together with other factors such as legal have succeeded in being constant obstacles on the road to equality. Most social groups, our parents and the media have socialized us to believe that the male gender is superior to the female gender. One can ask, does sex determine one’s abilities? Pursuing such a question may elicit an endless debate but a sex-based approach in determining gender roles is bias and oppressive to women and perpetuates inequalities and patriarchy. No wonder women have to fight for equality. Kyra Sedgwick says that, â€Å"†¦we are still not really supposed to want it as much as guy does. † But I think women should be able to make their own choices. I would want to socialize my children in a manner that they will see both genders as equal and worth as much respect despite the differences. I will also want to allow them freedom to choose what they want to be in life. I will not deny them opportunities on the basis of their gender. I will also encourage them to follow their passion provided they are within the range of acceptable careers and I will endeavor to support them. A number of questions puzzle me. They include; In agitating for equality, do women become more women or less? Is a woman more woman because she enjoys same rights as a man? Is it possible to invent a universally acceptable modality of determining gender roles so as to eschew the controversy? What provisions do our societies make for those individuals who do not qualify as average male/female? These questions leave me lost in the labyrinths. The first and second questions demand that women be careful when agitating for equality lest they lose their identity. Anyway what is so serious about losing one’s identity? If forgoing one’s identity will make one have a happier life then isn’t it better to forgo it. What should be pursued, identity or happiness? Addressing the third question will save us unnecessary debates while the fourth question rises out of my worry that there are some persons that are left out in the classification of genders and this could be unfair- a more inclusive definition needs to be adopted for a fair discussion. In doing away with the dual classification such terms as feminism and others that are so ‘poisoned’ will be avoided and may be a less controversial nomenclature adopted. Andrea Wong is a brave woman. From her early age she tried her leg in leadership, a field that was erroneously perceived as a reserve for men. Also unlike most women, Andrea Wong knows how, after falling, to get up, dust herself off and keep going. Unlike Wong, most women get resigned after their first failure. If women were like her, they would also be leaders like she is today and would be doing great exploits. Rachel Roy is another woman who impresses me. She goes for what she wants and she wants nothing but the best, â€Å" If I couldn’t work at Contempo, I didn’t want to work anywhere. † This shows a resolve that most women lack. She knows what she wants that is to be a designer, â€Å"her passion started in childhood and she has never wavered†. She is final in her decision. These two women not only set good example for me but also are good role models for women. From the pieces, it is clearly depicted that success for women is dependent on their attitude and not their gender. If women changed their attitude then they would favorably compete against men and it would be easier for them and tougher for men. Works cited Newsweek, October 15, 2007.

Use of Math in Auto Racing Essay -- mathematics math car racing

  Ã‚  Ã‚  Ã‚  Ã‚  Mathematics is found everywhere in life and work and auto racing is no exception. There are many applications of math in racing. The purpose of racing is to win and in order to do that there must be a lot of math involved. If you don’t use math and use it correctly then you will not win. Mathematics is involved in racing in two ways, the car setup and scoring an measurements. The car setup involves tire pressure, down force, wedge, aerodynamic Drag, camber, track bar and valance. The scoring system also uses math. In addition to scoring math is also used to measure different racing related subjects such as car weight, gas mileage time interval, qualifying, and the track characteristics.   Ã‚  Ã‚  Ã‚  Ã‚  Tire pressure is used as a setup tool that is akin to adjusting spring rates in the vehicles suspension. Increasing the air pressure in the tires raises the spring rate in the tire itself and changes the vehicles handling characteristics. In order for optimal performance the teams must know the proper p.s.i ( Pressure per square inch) for a certain tire on a certain track for a certain air temperature.   Ã‚  Ã‚  Ã‚  Ã‚  Math is also used in measuring the â€Å"downforce.† Downforce is the air pressure traveling over the surface of the car. This air pushes the car downwards which creates the term downforce. The greater the psi the greater the downforce which creates better tire grip for higher speeds through turns.   Ã‚  Ã‚  Ã‚  Ã‚  Wedge is another racing term that relies on math. Wedge refers to the relationship from corner to corner of the weight of the car. The weight on any corner of the vehicle affects the weight of the other three corners in direct proportion. The wedge determines how the car handles by either stiffening the wedge or loosening it up.   Ã‚  Ã‚  Ã‚  Ã‚  Aerodynamic drag is another math related racing factor. A number that is a coefficient of several factors indicates how well a car will travel through the air is the aerodynamic drag. Teams use specific tests to determine how to achieve the least amount of drag on the car in order to obtain the fastest speed possible.   Ã‚  Ã‚  Ã‚  Ã‚  Math is involved in the camber of a tire which is also very critical in creating the fastest car possible. Camber is the angle at which a tire makes contact with the track surface. The camber varies from tire to tire dep... ... degree of the angle of the track, usually the banking is the steepest in the turns. The banking can range from 0 degrees to 34 degrees which is significant to the team when preparing for a race.   Ã‚  Ã‚  Ã‚  Ã‚  Math is very important in the world of racing. In order to be the most competitive teams must know how to use math and use it correctly. Incorrect calculations can cause dismal performance, fines and be dangerous to the driver. Due to these reasons race teams accept no error in calculations and always make sure to use the math to their advantage. Math is used in different ways in racing. Math is used to determine the proper setup of a car and is used to determine the scoring and measurements of racing subjects. The car setup involves math in the tire pressure, downforce, wedge, aerodynamic drag, camber, track bar and the valance. Math is used in the scoring to determine how many points a driver receives each race and is used in measuring the car weight, gas mileage, time interval, qualifying and the track specifications. All of these are just some of the many examples of how math is relevant in all areas of life including auto racing.

Art Is an Expression

Art History 6A 19 November 2011 Triumph! Art is an expression that we as humans do as a way to express and communicate with others. Through art every painting/sculpture has an intended purpose and message/story to convey. No matter what race, gender, or class, one can understand what message is being shared or find an entirely opposite interpretation other than what the artist intended. It can relate to the individual on a personal level, and that’s the beauty of art. In this essay I will be writing about two pieces of art that have been around for thousands of years.I will be comparing and contrasting the Palette of King Narmer (back) and the painting â€Å"Ti watching a hippopotamus hunt. † Both murals contain symbolism, as well as concepts of life and death. Each in their individual way conveys a message of importance and triumph. The Palette of King Narmer dates back to the first Egyptian dynasty, from Hierakonpolis, c. 3000 B. C, it is flat in appearance and double -sided with engravings on both sides, each individual side separated into 3 distinctive sections by horizontal lines with the middle being the biggest.It stands approximately 25† inches (63. 5cm) in height and tapers down to a point. The structure of the piece is very similar to the outline of a shield. It is composed of a dark color slate, common rock found in Egypt. Unlike the Palette the painting of â€Å"Ti Watching a Hippopotamus Hunt† is much bigger almost double in size, standing 4 feet tall. It was created during the fifth dynasty, Saqqara, c. 2400 B. C. and is composed of painted limestone. Prior to the creation of the Palette of King Narmer, art was divided throughout Egypt.Egypt was divided geographically and politically into Upper and Lower Egypt. Society had an emphasis on becoming unified and the palate marks the unification of these two lands. King Narmer is famously known as the first king to rule these lands. The palettes’ historical importance m arks the transition from pre-historical to historical period in Egypt and serves as the foundation for generations of art glorifying kings. During the time of â€Å"Ti Watching a Hippopotamus Hunt† Egyptians had a very strong belief and emphasis in death and the afterlife.Death was rarely filled with a sense of fear, but instead embraced with open arms and seen as a necessary transition one must make to live in the afterlife. Egyptians constructed mastabas for the dead. For this reason there was a plethora of funerary offerings including statues, carvings, and paintings made and placed into mastabas. The Egyptians built their mastabas very similar to homes for the dead so when they entered the afterlife they would have all the necessities and luxuries they once had during their lifetime.Narmers palette was an object commonly used in the preparation of eye make up, used by the Egyptians mostly to block and shield out the sun. The palette is most likely a votive or gift to the gods. Whereas the painting of â€Å"Ti Watching a Hippopotamus Hunt† was a funerary gift made to honor loved ones who have passed and entered their next chapter in life. In both works of art, animals are portrayed but only in the palette do animals have true symbolic meaning. On the Back of the palette the upmost section portrays two cow heads one on each side, which appear to have human faces.This representation depicts a variety of interpretations: the goddess Hathor, or the goddess bat, or just a symbolism for the Kings power and strength, which is a common symbolism of a bull throughout Egyptian art. The true meaning of these symbolic bulls is unknown till this day due to the uncommon frontal portrayal of the bulls. Also in the back of the palette there stands a falcon, symbolizing the god Horus- protector of kings. The falcon is placed on top of a head sitting on papyrus representing Lower Egypt. This signifies the triumph and power Upper Egypt had over Lower Egypt.In th e painting of â€Å"Ti Watching a Hippopotamus Hunt† animals individually serve no significant value, but as a whole in Egyptian art a successful hunt is a metaphor for triumph over evil. In the palette of King Narmer there are a series of hieroglyphics used to signify the powerful King Narmer making Narmers palette the earliest existing labeled piece of art. In between the bullheads are hieroglyphics of a catfish (nar) and a chisel (mer) within a frame representing the royal palace. The fish also pays tribute to the Nile River since Egypt strived and lived off the river for all its resources such as food and water.In the painting of â€Å"Ti Watching a Hippopotamus Hunt† there are no hieroglyphics used because it was intended for the dead. Its purpose served to represent and honor the loved ones passed. In â€Å"Ti Watching a Hippopotamus Hunt† the artist incorporates a unique series of lines/patterns to bring structure and organization to the piece. This is po rtrayed in the water beneath the boats by a pattern of wavy lines that embody fish and hippopotami. In the uppermost of the painting the artist uses a series of fine grooves that lead into a commotion of birds and foxes resembling papyrus flowers.Similarly lines play a Important role in the Palette of Narmer. A series of Horizontal lines are used to break the palette into 3 distinctive sections. Without the use of lines, the palette would have no organization and would become chaotic. The portrayal of the body when referencing both Narmer and Ti is very similar. Showing the influence Narmers palette had in art. In both pictures the eye and upper body is in frontal view while the head and legs/feet are in profile view, one in front of the other, which was a very common depiction of important figures.It was believed that by showing the Egyptians in this way all the body parts needed in the afterlife would be properly expressed and available to the deceased when needed. Slaves and anim als were painted more natural and relaxed, and with a smaller scale in drawings to show there limited importance. In both pictures the artists illustrate both Narmer and Ti being the dominating and largest figure (which is called  hierarchical scale). In the palette of King Narmer, Narmer is significantly larger in his ceremonial beard wearing a bowling pin shape crown, which represents Upper Egypt.Attached to the end of his kilt is a bulls tail indicating the power and strength of Narmer. Behind King Narmer is a much smaller servant, most likely of high rank, carrying his sandals making Narmer barefoot. Throughout Egyptian art being barefoot symbolizes the person is on holy ground. In Narmers right hand he holds a club, ready to strike a kneeling warrior he holds by the head with his left hand. This once again signifies the power and strength of Narmer over his enemies. Below this scene are two bearded men most likely enemies of the king lying dead symbolic of how lethal and vict orious of a ruler he is.In the mastaba of a Ti the painting â€Å"Ti Watching a Hippopotamus Hunt† Ti is similarly portrayed. Ti is shown much larger and out of scale compared to his slaves depicted, representing his importance and social status. In Egypt a successful hunt was a metaphor for triumph over evil. Ti and his slaves are roaming through marshes, hunting hippopotami and birds. Ti unlike Narmer is distant away from the hunt, not engaging in the action of killing the hippopotami but yet he is still present over looking his slaves during the hunt.He is a neutral observer of life, resembling his Ka being at peace. Both murals use a variety of lines, symbols, and details not only to focus on the importance and triumph of Narmer and Ti but also make a structured organized piece of art. The palette of Narmer represents this triumph over evil more straightforward being that Narmer has already killed two of his foes about to kill another, holding in the palm of his hand the power to give life or death. On the other hand the painting â€Å"Ti Watching a Hippopotamus Hunt† is metaphorically representing victory and triumph through the hunt.
