The Physics Of A Wind Tunnel - 1397 Words

A wind tunnel is a key instrument used by Aerospace engineers to accurately measure the aerodynamic forces and moment on an aircraft model. The aerodynamic forces and moments that the model experience then can be compared to the real-life conditions that an aircraft experiences in real-time. An important in tool that allows us to find these different force is the L.A. Comp wind tunnel’s pyramidal balance. This kind of balance allows aerospace engineers to measure all the force: lift, drag, and side force; as well as all the moments: pitching, yawing, and rolling [1]. Figure 1, you are able to see where each of these forces are action and along which axis. Figure 1: Forces and Moments on an Aircraft It is important to understand where all these forces and moments are acting on an aircraft to understand how each one affects and aircraft. A crucial step before actually gathering these force and moments is to calibrate our balance. The objective of this experiment was to calibrate the L.A. Comp wind tunnel and to develop calibration plots that will later be used in future experiments. The L. A. Comp wind tunnel is a closed circuit wind tunnel that has been at the University of Oklahoma. It is a subsonic wind tunnel powered by a 400hp electric motor that spins three-seven-foot propeller at a constant speed. The speed of the air in this wind tunnel is adjusted by the pitch of the propellers adjusted by a hydraulics. The L.A. Comp wind tunnels usually operates at 150mph.

Well, there are programs our government provides to our elderly to help them buy food, find a place to live and most importantly, help insure them. Medicare is a program that was initially created by Harry S. Truman in 1948, but Congress failed to enact it (â€Å"Curing the Health Care System†). Later it was refined by LBJ in 1965 as part of â€Å"Great Society† to help the â€Å"war on poverty†. Medicare benefits millions of senior citizens over 65 by giving them free health care or helping pay part of it. Before Medicare there was private insurance that helped people, but with Medicare a lot more people have access to health insurance. Today, Medicare provides over 52.3 million Americans with affordable health insurance. The government started taking action to help the elderly through social problems in the mid-19th century. In May of 1964, Johnson had summed up his grand vision for America in a speech at the University of Michigan, he declared that â€Å"the Great Society demands an end to poverty and racial injustice... just the beginning†(Johnson). Before LBJ and Congress brought about the first major change in Social Security, any government system that provides monetary assistance to people with an inadequate or no income, by establishing Medicare for the seniors, elderly people bought their health insurance from privateShow MoreRelatedLanguage Bridges And Barriers Of Language1198 Words   |  5 Pagesfirst amendment, diversity, and the quality of education received in the U.S. Therefore, my stance is that the U.S. should not have an official language and that the state of Arkansas does not need language related legislation.

Literature Review on Liver Biopsy Samples †MyAssignmenthelp.com

Question: Discuss about the Literature Review on Liver Biopsy. Answer: Introduction The human body is composed of extracellular materials and cells, which have been produced by cells. Histology is the discipline focusing on the microscopic examination of the human body components(Alturkistani, Tashkandi, Mohammedsaleh, 2016). Through histology, it is possible to understand the organization of human body organs and tissues. It consists of broader aspects of microscopic anatomy. There are different methods that can be used to examine structures of cells and tissue characteristics. Histological studies are important in the autopsy, forensic investigations, education, and diagnosis (Black, 2012). This article focuses on the literature review on the advantages and limitations of histology technique used to examine the liver tissues. Literature Review Liver biopsy Needle biopsy is an important histological technique used to examine liver tissue. With this technique, studies have found that it is possible to manage liver diseases(Aziaripour, Lagerweij, Scharfbilling, Jadczak, Willershausen, Van Noorden, 2016). Liver biopsy seems to be easier and safer to use as it involves the use of open and laparoscopic, transjugular, and percutaneous biopsies(Suriawinata Thung, 2015). Percutaneous allows for the use of suction needle and cutting needle techniques in examining liver tissues. This technique is least invasive, least costly and most common liver biopsy. In fact, suction needle technique offers an adequate specimen for evaluating the histologic and related ancillary studies(Liversupport.com, 2017). However, the complications leading to specimen outcome can cause inadvertent biopsy of adjacent organs like intestine, pancreas, and kidney(Suriawinata Thung, 2015). Additionally, transjugular or transvenous is an important liver biopsy method. It involves the use of catheter through the inferior vena cava, right vein, and internal jugular vein(Suriawinata Thung, 2015). The catheter technique provides a second-line procedure, especially in patients suffering from coagulation disorders, gross ascites, fulminant hepatic failure and severe obesity. Studies have indicated that transjugular technique poses considerable costs, time, and effort(Suriawinata Thung, 2015). Indeed, the percutaneous biopsy is affordable technique compared to transjugular. This is because; it involves the use of smaller fragmented specimens. Nonetheless, catheter technique allows for the use of better needles thus improved the specimen quality(Liversupport.com, 2017). The complications relating to this technique because of the multiple specimens include inadvertent biopsy, contrast-related reaction, and arrhythmia. Laparoscopic method of liver biopsy offers direct visualization of peritoneal and liver cavity. The technique allows for the use of wedge and needle biopsy, as it involves the use of larger specimen. The users of the technique have recognized the sensitivity of the chronic liver diseases and cirrhosis like viral hepatitis, primary sclerosing cholangitis, and nodular regenerative hyperplasia(Black, 2012). Conversely, laparoscopic bariatric surgery is viewed as an expensive and invasive method. With this technology, Avwioro, Iyiola, and Aghoghovwia explained that the risk of hemorrhage and anesthesia due to the invasive nature of the method(Avwioro, Iyiola, Aghoghovwia, 2010). Laparoscopic bariatric surgery is popular for the obese patients thus increase the evaluation of intraoperative biopsies for fibrosis and steatohepatitis. Computed tomography has also been used as a liver biopsy technique. This ultrasound-guided technique involves the use of fine-needle aspiration. The computed tomography avoids the use of intersecting vessels and visualizes hepatic lesion(Suriawinata Thung, 2015). For cytologic or histologic diagnosis, it is possible to handle complex anatomy cases based on the space-occupying lesion. Scholars have argued that multiple aspirations ensure adequate specimen thus makes the interpretation achievable(Black, 2012). Similarly, the cell block evident in the ultrasound-guided technique allows for the additional staining and increase sensitivity(Suriawinata Thung, 2015). However, controversial issues have emerged regarding the computed tomography because it allows for the persistent of malignant cells. Interestingly, this technique is beneficial to cirrhotic patients has it reduces the hemorrhage risks compared with transcutaneous biopsy. The liver biopsy has proved useful in evaluating patients with liver problems, especially space-occupying lesion(Liversupport.com, 2017). This technique is critical for patients with allograft dysfunction, steatohepatitis, and chronic viral hepatitis thus assesses the level of liver damage. In most cases, where the clinical diagnosis generates doubt regarding acute hepatitis, liver biopsy becomes critical. In fact, where there are multifactorial causes of acute hepatitis or mistaken working diagnosis, the liver biopsy defines the situation accurately(Ong, Gravante, Metcalfe, Dennilson, 2013). Liver biopsy has proved to be relatively safe despite being an invasive procedure. Conclusion The liver biopsy is an important histological examination technique that is based on specific routine. The systematic approach ensures diagnostic findings are accurate. It considers various anatomic structures of the tissue leading to a meaningful diagnosis. Importantly, the article has focused on the liver biopsy techniques in examining the damages and injuries on the liver tissues. It has analyzed the findings of different studies relating to the histological techniques for examining liver tissue. Bibliography Alturkistani, H. A., Tashkandi, F. M., Mohammedsaleh, Z. M.
