Aerodynamics and Propulsion Principles Coursework - 2

Aerodynamics and Propulsion Principles - Coursework Example An example of using this technique is Bell X – I which is the first airplane to break the sound barrier. The achievement of this amazing feat, considered impossible until then, is attributed largely to its ‘super thin wings’ (Bell X-I). The supercritical airfoils differ from the conventional airfoils such that they have comparatively flat at the top. Their unique design limits the rise of drag forces even after the critical Mach number is reached. Such airfoils have successfully been utilized in TACT aircraft program run by NASA Dryden Flight Research Center (Cury). The figure shows the above-mentioned control surfaces and the functions they perform. All the control surfaces work on the principle of creating drag for the incoming wind thereby changing the direction of the wind. Due to this change in velocity, a momentum change occurs which causes a force to act on the control surface and the desired movement of the aircraft is achieved this way. The ailerons tilt the aircraft around the longitudinal axis. They are always installed in pairs. The opposite motion of the two ailerons creates a couple which acts on the longitudinal axis to cause the desired motion. Anderson defines static stability in these words â€Å"If the forces and moments on a body caused by a disturbance tend initially to return the body towards its equilibrium position, the body is statically stable†. Hence a statically stable plane will be that aircraft which can maintain a continuous balanced flight with a constant angle of attack. In case of a wind gust causing the angle of attack to increase, the resultant center of pressure (the point where resultant lift force acts) will shift forwards from the center of gravity of the aircraft and a resultant moment will act that will restore the initial position of the aircraft.

Oncology Our department of oncology delivers comprehensive treatment for cancer for both the adults and children with hematologic malignancies or solid tumours. Our aim is to provide the best possible care to patients,  build a world recognized environment for clinical research and laboratory. Biological, novel drug and immunologic targeted therapies and gene therapies are being intensively studied within the department to determine if these therapies can be used for cancer treatment. Members of the department collaborate with allied health professionals and physicians in related medical specialties for example: the Pain Clinic, Radiology, Psychology and Psychiatry, Infectious Diseases and also all the surgical subspecialties in order to ensure that cancer patients with their families have access to total care for their psychological, physic al, spiritual and emotional needs. The department of oncology diagnosis and treatment of every kind of cancer, including: head and neck tumors, brain tumors, kidney cancer, ovarian cancer, sarcomas melanoma, gynaecological and pancreatic cancer, biliary cancer, neuroendocrine and hepatoma. A few days back, our specialists successfully grafted patient’s brother’s bone marrow into hers. The patient was only a few months old and the doctors were really happy with the outcome as the cancer was in its last stages (Oncology in Minnesota, 2011). Gastroenterology Gastroenterology department provides medical treatment and expert diagnosis for patients with disorders of the liver, gallbladder, oesophagus, pancreas, stomach, small intestine and colon.  Our Gastroenterologists use the most recent endoscopic advances to carry out hundreds of minimally invasive procedures every month. These include sigmoidoscopy, colonoscopy  and state-of-the-art procedures such as endoscopic ul trasound (EUS) capsule endoscopy and  endoscopic retrograde cholangiopancreatography (ERCP). Apart from these services, other innovative procedures and treatments options include: Endoscopic Pancreatic Function Test, Cryoablation for Barrett’s Oesophagus, Endoscopy Therapy for IBD and Extracorporeal and intraductal Lithotripsy. The most common diseases we see in this department are Constipation in children and adults, diverticulitis, diarrhea, helicobacter pylori, gall bladder diseases, iron deficiency anemia, peptic ulcers, ulcerative colitis, nausea and vomiting, sigmoidoscopy and inflammatory bowel disease. A few days back, the department treated a patient who was unable to swallow food and liquid. Initially we could not find the cause but then it came out to be achalasia. In achalasia the oesophageal sphincter muscle does not relax normally. As medications are not an effective we performed a surgery, which fortunately was successful (Department of Gastroenterology & Hep atology, 2011). Pulmonary: We use the radiology department and the path lab for various tests, and X-rays. Radiological tests such as echocardiogram, ventilation perfusion scans, electrocardiogram, and CT scans are performed on these patients for their quick and efficient diagnosis. Several of the blood tests that we carry out are the LFTs

Social theories help Essay Example for Free

Social theories help Essay Social theories help us to understand the world and the society in which we live in and to interpret why people behave the way they do in the context of the existing social norms. In sociology, rational choice theory and the institutional paradigm aid us in exploring various social aspects in clear detail. The key difference between the rational choice theory and the institutional paradigm rests on the focus of each of the theories. For instance, rational choice theory addresses the pursuit for self-interest of human beings and their capacity to make choices that are generally based on the costs and benefits of their individual actions. On the other hand, the institutional paradigm maintains the belief that social structures have important roles in social relations and that these social structures influence the behaviors of human beings in every possible way. Rational choice theory also asserts that even our most altruistic actions and decisions have their innate strands of self-interest despite the observation that such actions and decisions are seen as selfless. Moreover, the theory also seeks to understand why people are inclined to work as a group in meeting a common goal even though the realization of the goal or even the process of reaching that goal may become inconsistent with the personal welfare of each of these individuals. The theory also finds that issue intriguing in more complex and larger human organizations since the difficulties present become larger as well. While rational choice theory espouses the idea of individuals able to come-up with informed decisions which in turn lead to how the society becomes structured, the institutional paradigm gives room for â€Å"accidents† or unintended consequences. More specifically, the institutional paradigm asserts that even historical accidents can happen, outcomes that are not the results of the rational decision-making process of an individual or a group of individuals. There may be people who were simply at the right place and at the right time, thereby resulting to consequential decisions that are neither planned nor carefully thought of in a rational way. Another key idea of the paradigm is the idea that the social institutions created by human beings such as social rules are open to change since human beings can undo the things in the society that they have set forth for themselves. Both the rational choice theory and the institutional paradigm can explain the issue of the widespread influence of religion such as Christianity and its religious practices in the contemporary society since it began. Rational choice theory will argue that Christianity and its practices have survived the years because people have chosen to integrate the religious edicts into their lives based on how they promote the interest of the followers. People tend to devote themselves to religion in general because of the benefits they can get weighed against the costs of their decision to follow the religion. Without the benefits, people will hardly join Christianity or any religion in general. On the other hand, the institutional paradigm will interpret the influence of Christianity as a result of the force of social norms on people. The rulers at the time and the high-ranking officials at the time may have compelled their subjects to join Christianity and that force was carried over through the following generations until it became a social norm. People may not necessarily have resorted to their rational decision-making capabilities since they do not have the power to resist the social norm. As a result, individuals become simply inclined to become Christians or followers of any other religion even without depending on their rationality and their pursuit of self-interest.

Companies to Watch: The Gap and Nordstroms :: essays research papers fc

  Ã‚  Ã‚  Ã‚  Ã‚  I chose to research two very different apparel retail stores. The GAP, Inc. and Nordstrom, Inc. are very interesting companies to me because they deal with something that is very important to me and a lot of people, clothes. Everyone buys and wears clothes, and these are two companies who have succeeded in this venture. They both started out with the same intentions, to sell apparel through specialty stores, but at this point Nordstrom’s has been more successful.   Ã‚  Ã‚  Ã‚  Ã‚  In theory these two companies are very similar because they are trying to accomplish the same thing. They both sell apparel, shoes and accessories for women, men and children through specialty and clearance stores. The clearance stores mentioned are Nordstrom Rack and GAP factory outlet stores. They also stress the use of personalized customer service. The GAP and Nordstrom feel that good customer service is the way to keep customers happy and thus keep them loyal. Because of this, they have many employees to serve their customers and spend a lot of time training these employees.   Ã‚  Ã‚  Ã‚  Ã‚  These companies are also set up in the same way. They each have a chairman, president, and a couple of vice presidents. They both operate on the New York Stock Exchange. Another interesting similarity is that they both are based out of the west coast, The GAP in San Francisco and Nordstrom in Seattle. But this is where the similarities end.   Ã‚  Ã‚  Ã‚  Ã‚  The sizes of these two companies are very different. The GAP is a global retailer with about 3,700 stores and 166,000 employees worldwide. Nordstrom on the other hand has about 77 stores nationwide and 43,000 employees. It does operate one international boutique, Faconnable, mainly in Europe. The GAP has three brands including GAP, Banana Republic and Old Navy, all operating in their own stores. Because of this huge difference in size, the GAP has much higher revenue than Nordstrom, but this doesn’t mean that it’s a better company.   Ã‚  Ã‚  Ã‚  Ã‚  In the news lately, the GAP has been under a lot of scrutiny because its sales have been down so much causing their credit rating to lower as well. Investors feel that this is due to the sharp slowdown in consumer spending, growing competition and series of fashion misses. It has too many stores open to sustain this major hit on sales. They have very little debt, but analysts think that this combination spells a future bankruptcy.

Wireless network management

The 802.11 protocol is defined for a wireless LAN (Local Area Network) and is based on a cellular architecture in which the network is divided into cells where each cell (called a Basic Service Cell (BSS)) is controlled by a base station called an Access Point (AP).The basic access mechanism implemented in the protocol is a Carrier Sence Multiple Access with Collision Avoidance (CSMA/CA). The CSMA protocol works as follows:Â   if a station wishes to transmit information through it network, it senses the medium. In case the medium is busy (another station in the network is currently transmitting information) then the station will delay its transmission requests to a later time. Otherwise, the medium is free and the station is allowed to transmit the desired information.The problem with the CSMA protocol is the case where a collision occurs. A collision may occur if two different stations sense the medium as free and begin to transmit information. For this purpose, we use a collision avoidance mechanism: a station willing to transmit senses the medium. If the medium is busy, it defers its request.Otherwise, it sends an RTS (Request To Transmit) which includes the source, destination and the duration of the transaction. If the medium is free then the destination station will respond with a packet called CTS (Clear To Send) which will include the same duration information and once the source station receives this packet, it starts to transmit. The destination station checks the CRC (Cyclic Redundancy Check) and sends an acknowledgment package (ACK).Receiving the ACK informs the source station that no collision had occurred. If the source station does not receive the ACK it will keep resending the data or will throw it away after a given number of retransmissions.When a station wishes to join an existing BSS, it needs to receive synchronization information from the BSS’s AP. First, the station needs to go through the AP’s authentication process. Durin g this process, the station and the AP exchange information proving to each other that each side is familiar with a specific password.

The Hippocratic Oath - 1099 Words

What makes us who we are? What makes our history, religion, and our literature? What about our philosophy, science and our art? All of this is are the humanities. The humanities studies every aspect of the human experience all the way from the beginning of time. It is such an open and vast topic, that I will mostly focus on the medical part of the humanities, because that is where my field of study is. The medical field goes all the way back to the Hippocratic Oath which was written in the early 5th century BC. There were also many people that helped push the medical advancements along like Leonardo Da Vinci, Herophilus, and Erasistratus. Leonardo Da Vinci studied anatomy and drew diagrams of the human body that never had been seen before. Herophilus and Erasistratus studied neuroscience and the study of the human brain. Herophilus discovered the difference between sensory and motor nerves, and Erasistratus theories contradicted those of Herophilus. I will also discuss the responsibi lities of a learner, and what learners should do to help themselves and our society. As I started my research, I realized that the humanities is a very complex topic. But in simpler terms, the humanities is the study of us, humans. The humanities pose the â€Å"what if† question in every aspect of our lives from literature to scientific discoveries.
