Sickle Cell Anemia Essays (247 words) - Hemoglobins, Hematopathology

Sickle Cell Anemia Hemoglobin, an oxygen carrying protein in blood, is sometime altered in people causing interruptions in the circulation of blood. This is known as Sickle-Cell Anemia. In the United States, Sickle-Cell Anemia is found mostly in blacks. About 1 in 400 blacks in the United States have the disorder. In Africa, and parts of the Middle East, Sickle-Cell Anemia can be found, not just in the United States. In infants, it only takes about 6 months after birth for symptoms of Sickle-Cell Anemia to appear. These symptoms include the following: swelling of hands and feet; and enlargement of heart and abdomen. Sexual maturation may be delayed in the adolescence stage of life. Later in life, leg ulcers and infections can occur due to blood flow disturbance caused by the disease. Sickle-Cell Anemia gets its name from the sickle, a sharp, crescent- shaped tool. When a person has Sick-Cell Anemia, their red blood cells change in shape due to the altered hemoglobin in the blood. When the oxygen in the blood cells is reduced for any reason, the cells become oddly shaped. They are shaped like a sickle. This blood disease is inherited from the parents, much like other traits. The gene for Sickle-Cell Anemia is codominant with the gene for normal blood hemoglobin. When the heterozygous form occurs, that person is said to be a Sickle-Call Carrier. He or she has the gene for the Sickle-Cell Anemia, but does not show the symptoms of the disorder. Sickle-Cell carriers are partially resistant to Malaria.

Brown Black and white all over essays

Brown Black and white all over essays Thoughts on: Brown and Black and White all Over Racism is a wild fire, fed by fear, and hate, sparked by ignorance, and misunderstanding. This was the feeling I got while and after viewing the play Brown and Black and White all Over, played by Antonio Sacre. Many parts of his play hit and emotional nerve inside me. Antonio Sacres play contained passages that had me riding an emotional roller coaster. Sacre, a self proclaimed storyteller had me in a state of indecision, somewhere between laughing at and feeling sorry for the characters of his story. Antonio Sacres play was put on by his drama class, which consisted of about 5 girls from a school whose average student read at 15% of the national level. Sacre had me laughing at these kids antics and speech. They spoke in broken English and slang saying Hey man. How do expect me to learn all dis man? Huh? So I gotta learn all dis words? This had me and most of the audience laughing. Haha. these kids talked with different speech patterns than most of us. They are funny. HaHaHa. Then it hit me. These were underprivileged kids who didnt think they talked funny because this was how they talked, every day. I was laughing at them because of this? How could I be that rude? I and about 300 other people sitting in a nice padded chair, in a beautiful gy m, at a private school in one of the most affluent towns in the world, was laughing at these kids who were stumbling over lines and talking with a different accent. I was hard pressed to laugh at anything for the rest of that segment. Another part of Antonio Sacres play that stood out to my psyche was when Antonio was visiting the conference on Racism in the Californian redwood forest. The group was talking about stereotypes until a person of color says: Man, I cant believe the injustices in this world, man. My bro got caught wit a little bit of pot and got 2 years....

Responsible tourism - Essay Example However, the Park has untapped natural resources such as rivers, rocks, lava flow and dust-elephants. All of these can be utilized to generate streams of revenues for the survival and growth of the region. Literature on responsible tourism suggests that poverty alleviation is possible if all the stakeholders work in cooperation to achieved the defined goals. However, this requires all the stakeholders to accept and discharge responsibility. Through a case study analysis it has been identified that the locals play a critical role in the sustainable development of any region. Motivating the locals becomes a major issue which can be shouldered by the NGOs. The tourists, the hotel operators and the tour operators, each have responsibility towards sustainable development. ... km. It is nine times bigger than the Maasai Mara National Reserve (Expert Africa, n.d.). The Park lies to the east of the Nairobi –Mombasa road, equidistant between Nairobi and Mombasa, amidst flora and fauna, and the meandering Galana River (Kenya Wildlife Service, 2013). The Tsavo river flows west to east through the national park, it borders the Chyulu Hills National Park and the Mkomazi Game Reserve in Tanzania. The climate here is warm and dry. The Tsavo East National Park was once home to 35,000 elephants, reduced 4,300 by 1988 due to poaching from Somalia (Joshua, 1993). However, under pressure from conservationists and western donors, and under new leadership, corruption was cleaned up and there was ban on trading in ivory. Investments were brought in which facilitated the growth of herds; tourism too picked up as infrastructure was enhanced. The elephant population in the entire Tsavo ecosystem as of 2011 was 12,570 (McKnight, n.d.). The biggest draw of the Park is th e herds of dust-red elephants that bulldoze their way around. Visitors to the park can watch wildlife under a huge sky and experience the wilderness in solitude (Expert Africa, n.d.). In addition, is the Aruba Dam, located on the North Bank of the Voi River, which makes a great game viewing destination.

A Case Study On Aspergers Syndrome Education Essay

A Case Study On Aspergers Syndrome Education Essay The Aspergers Syndrome is a mild form of autism which is seen in children of school bearing age. Yet since it is a mild form of the neurobiological disorder, some children who are suffering from Aspergers Syndrome are enrolled in mainstream classroom in order to interact with other children without the disability. This research will disclose how a child who is suffering from Aspergers Syndrome might react into the learning development when they are exposed with other students. Over the years it has been noticed that it is not always in the best interests of children with Aspergers Syndrome, a mild form of autism to be working in groups in a mainstream classroom for their social development. Yet recent studies show that incorporating Aspergers children in mainstream schools might be able to help the childs social development. Those children whose needs are not at the severe end of the spectrum disorder were successfully included in mainstream schools and were able to cope accordingly. There will be a need for flexibility and recognition that the child may need some approaches different to those used for other learners. These techniques and practices will be disclosed in the latter parts of the paper. Currently the writer is working with a child who was diagnosed with Aspergers Syndrome. Though the child displays a mild form of autism, the child was enrolled in a mainstream school. Due to this, the researcher would want to determine how a mainstream classroom would be able to support this child. According to Downshen (2010), there are few facilities which specialises in providing the special needs of children diagnosed with Aspergers Syndrome. Some of the children with this disorder were placed in mainstream schools, and their development would depend greatly upon the support and encouragement they can receive from parents, teachers, caregivers, and peers. For those other families, they prefer to place their children in a specialised institution for those with learning disabilities or autism. Many people with Aspergers Syndrome can function accordingly in most aspects, so the condition does not limit a childs development and success in academic and social standing. They will still be able to cope and learn as well as their peers in the classroom (ibid). Accordingly, in a study conducted by Epp (2008), she has indicated that kids with Aspergers Syndrome can still excel in mainstream classrooms and be enrolled in public schools. Since some schools do not accept children who have violent and screening behaviors, there is an instrument being used by schools to determine the verbal and cognitive skills of children. This tool will be discussed in detail in the latter parts of the study. Aspergers Syndrome is named after Hans Asperger, a paediatrician who first described the behaviour patterns which defines the illness. In 1940s, most of Aspergers patients who were suffering from the condition were males. Though they had normal language development and intelligence, the boys were impaired in their social skills, and have poor motor skills and coordination, as well as inefficient when communicating with other peers (Downshen, 2010). The illness was then diagnosed as a mild form of autism by the Asperger Syndrome Coalition of the United States. Most patients who suffer from the illness are children in the ages of 3 to 9 (Ibid). It is characterized by displaying poor social interactions, odd speech patterns, obsessive behaviours, and other unusual mannerisms in the age group of the child. Medical practitioners and educational staff were able to determine who among the children displays Aspergers Syndrome since sufferers have limited facial expressions and some were known to be obsessive in their routines. A small change in routine might set a tantrum, wherein the child would have unusual sensitivity to given sensory stimuli, such as sensing a bright light which the other kids are not able to see, and hearing a high-pitched sound which was unheard by other children. According to Downshen (2010), most children with Aspergers Syndrome were able to function and cope normally in daily activities. Aside from some odd behaviors and being socially immature, there are few other indicators that a child might be suffering from the illness. A child with Aspergers Syndrome might have motor delays, limited interests which would depend on routines, clumsiness, and unusual preoccupations. They tend to be aloof from other children with no social understanding of their actions. When they enter adulthood, they would have difficulty in demonstrating empathy for their peers, as well as be socially unable to relate to their peers. Some say that the disease lasts a lifetime with no immediate cures, yet the symptoms could wane over time, and early detection of the disease could help the child development in the areas wherein they need support (ibid). Similarly, Aspergers Syndrome is a part of Autism Spectrum Disorders. Autism Spectrum Disorders are a wide-range of developmental disabilities which includes but are is not limited to autism and other neurobiological disorders with similar characteristics and symptoms (ibid).The term spectrum disorders is made in such a way that symptoms are similar with each other, and though there different combinations of such symptoms, the degree of the illnesses severity could be on completely opposing sides. For example, two children might be diagnosed with the same neurobiological disorder, yet they might display different coping mechanisms and speeches. One might be extremely intelligent in academic works, but lacking in coordination skills in sports, whilst the other might be extremely gifted in physical activities, yet have a hard time coping with academic reports. There is a wide range of skills and abilities which could affect a child who is suffering from spectrum disorders (ibid). The study will only focus on the autism behaviour of Aspergers Syndrome, which is a mild form of autism. The researcher will not include studies and references for other forms of behaviours, and is limited on the study for AS only. The researcher does not wish to find a cure for the disorder, but aims to determine how to help children with AS be able to cope properly in mainstream classrooms without compromising their ability to learn. The research will focus on one case study of a boy with AS whom the researcher is currently working with. This boy is enrolled in a mainstream school and a mainstream classroom, both of which information will not be disclosed for the sake of keeping the boys personality and the schools name anonymous. The researcher does not wish to make the boy and the school as inanimate objects of the study, but would rather use them as a means of gathering information for the general welfare of children with AS. Lastly, the research will not include other documented cases of AS aside from the case study, except for references sake for the literature review. The educational instructors and practitioners in the said school will be interviewed for their opinions about the behaviour of the boy, and how he is able to cope in the mainstream school with his peers of the same age. The final format of this paper will contain six chapters. The first chapter is for the introduction, wherein the basics of the research would be disclosed. The Introduction would also contain the research questions and objectives. This would be followed by the second chapter which is the literature review which will inform the readers of what are articulately known today about the topic. All literatures which will be reviewed will be followed by the researchers narratives, explanations and opinions about them about the information they contain. There would be a confidentiality agreement between the participants of the case study, interviews, and other participants in the study. Before the start of the case study, the researcher will ask for the permission of parents and caregivers of the peers and classmates of the boy with AS. These caregivers and parents might have qualms about involving their children in such a study, but there could also be those who would willingly give their children the chance to be involved in such a complex study which could help children with AS in the future. After gaining the permission of the caregivers of children, the researcher will then set up the period of case study for the child with AS, and his educational providers and instructors. The researcher would establish the environment and basics of the case study, and will prepare all the needed materials to create a holistic environment. Finally, the researcher would give all educational instructors and participants their own forms for confidentiality agreement. They would be assured that their personal information will not be disclosed to any third party, and all results of the study would be purely academic. 3.8 Data Collection Methods Both primary and secondary data methodologies would be utilized in this research. The following would be the sources of data and information: 3.8.1 Primary Data All the primary data would be gathered from the primary sources of information of the researcher. These methodologies would be comprised of the case study, observation, and interviews with concerned individuals such as primary caregivers, parents, peers, and teachers of the child. They will be asked and gauged according to their proximity with the topic, as well as their experiences in coordinating with the child with AS. The primary data will also be taken from the researchers observation of the participants. These observations would be able to say a lot about the details of the research such as the credibility of their narratives and experiences. They will be asked about their experiences, and the researcher would be able to see how accurate their responses are based on their facial expressions and reasoning. 3.8.2 Secondary Data The secondary data would be derived from the contextual analysis to be done by the researcher. The researcher would perform a thorough and diverse investigation of the topic about recently published materials and articles for the line of research. The author would also indicate which among the materials are the most relevant to the study. 3.9 Conclusion The researcher would be an explanatory research with the interpretative approach which would be used to explain how the boy is coping up in a mainstream situation, as well as accurately interpret the situations and consequences of what the case study. After thoroughly explaining the researchs methodologies, the researcher have clarified the following: Case study the case study would be used in order to observe the child from his natural environment and how he is coping in a mainstream classroom for normal children. By having the case study, the researcher would be able to actively comprehend how practitioners could provide the child with adequate care for his situation. Observation the researcher would use the power of observation, such as observation sheets and narratives which would be compiled and scrutinized upon completion of the materials and data. Interviews people with close ties to the child would be interviewed for their intervention and advices about the topic, as well as how the child copes in an everyday setting. Contextual analysis by using this research method, the researcher would be able to understand how other experienced individuals have dealt with the research topic. These methods would help the research determine how working in a mainstream classroom will support a child with Aspergers Syndrome. He will also be gauged based on his ability to cope with other children who do not have neurobehavioral disorder, and how his learning in the classroom impacts the learning of other people. The researchs aims would be closely tied with the research methodologies. The data would be analyzed in a timely and accurate manner. The researcher would only focus on one child with Aspergers Syndrome, and focus on how he is coping and what are his needs in a mainstream environment. Doing such will keep the research accurate and valid. The narratives of other involved people would be judged according to their reactions and based on the observation, which would be based on how they react and answer questions. With the researcher asking in such close proximity, there would be little room for untruthful narratives.

Physics of Hydraulics :: physics hydraulics

Missing Figures/Equations History The type of physics that I will be presenting is a branch of Fluid Mechanics. Fluid mechanics studies the physics of gases and liquids. Hydraulics is defined as: "a branch of science that deals with practical applications of liquid in motion." Merriam-Webster's Medical Dictionary, via www.dictionary.com The science started over thousands of years ago with Aristotle (384-322 B.C.) and Archimedes (287-212 B.C.). Many European scientists also contributed to hydraulics, including da Vinci, Mariotte and Boyle. The scientist who discovered the main principle I will be talking about is Pascal. A French scientist who studied math and physics. His work included studying atmospheric pressure, conic sections and the principles of hydrostatics. After Pascal there is Bernoilli, Franklin and Froud, who all also contributed to the science of hydraulics. How it works (the physics part) The basic rule of using hydraulic power is Pascal's Principle. Pascal's Principle: pressure exerted on a fluid is distributed equally throughout the fluid. Hydraulics uses incompresible liquids so the applied pressure from one end (small arrow) is equal to the desired pressure on the other end (big arrow). The big arrow is pointing toward a piston that is free to move, and is sometimes connected to a rod. When the force is applied, the piston moves up or down. The equations are: equations Of course, as Prof. Newman says, "there is no free lunch," In order to move the larger area, the smaller area has to move a lot in order to move the larger area a little. The larger area is nine times greater than the smaller area. In order to move the larger piston one inch, the smaller piston has to move nine inches. The Uses of Hydraulics Hydraulics are used in many ways. Most of them are used everyday and not even thought about. Here are some examples of how hydraulics are used. They are all machines (I'm a mechanical engineer!) Car Brakes Car brakes work when you push the brake pedal, it pushes the small piston. The piston applies pressure on the brake fluid, which press the brake pads on the large pistons. The brake pads come into contact with the brake drum and slows the car down, eventually stopping the car. Airplanes Airplanes and jet planes use hydraulics in many places. * Adjusting wings * Putting out/bringing in landing gear * opening/closing doors Real Life Hydraulics Unfortunately applying hydraulics in real life isn't so simple. There are a few things to consider if you are planning on designing and building hydraulic equipment.
