Manufactoring case study Example | Topics and Well Written Essays - 1500 words

Manufactoring - Case Study Example This part is also required to be stronger. Moreover, the extreme humidity may also damage the same by the formation of rust throughout the metallic body of the tool. However, there also some of the punch tools that are made up of plastic, especially the lever (Paper Pro Inc., â€Å"Home.†). The product generally stays in the normal room temperature and humidity. However, with the extreme humidity it might rust its surface. It generally stays in the hands of users therefore the presence of moisture in the hands might also form rust. Moreover, it is also observed in the table or shelf of an office or an educational institute or in the living room (Davis 1-58). The parts that are more vulnerable to be damaged after the execution of physical pressure are the punches and the lever. These parts are directly connected to the body of the punch machine and with the holes of the same. It is also connected with the part of the instrument, where the pressure is exerted (Davis 1-58). The inside dimensions of the lever and punch are very important aspect for a punch machine to be effective. The proper dimension of the lever for the satisfaction of the customer can be achieved by exerting less pressure for making paper holes. Moreover, the proper dimension of the punches is also important as leads to the formation of the holes at the specific dimension in papers (Davis 1-58). There are also certain non-dimensional attributes that are required to be considered. These include proper smoothness and color throughout the body of the tool. The body of the tool is also required to be designed as per the segments of the customers. If the tool is used in the corporate offices, it is desirable to have a corporate look. Further, if the tool is used by a young boy or a girl, it is required to be designed accordingly (Davis 1-58). The material that is used in the punches and in the lever is generally of steel. Steel is one of the strongest alloys of the

Sciavo Case Study Example | Topics and Well Written Essays - 1000 words

Sciavo - Case Study Example Later in the year 1990, Mrs. Shiavo was diagnosed with a â€Å"Persistent Vegetative State† (PVS). Her husband Mr. Schiavo accepted that her condition was very critical, and her recovery was remote since all healthcare means had failed to revive her. He decided to work on what he assumed his wife would wish. He said my wife would not have chosen to continue being kept on an artificial life-supporting machine. Mrs. Shiavo’s parents strongly opposed her husband’s stand and subsequently one of the most popular ethical dilemmas unfolded (Perry,Churchill and Kirshner, 2005). This case spurred controversy in the legal, medical, ethical, political and social domains. The case threatened to loosen the long-standing legal and ethical positions, which enabled individuals to control medical interventions executed on them. After so many petitions, hearings and numerous appeals, the Florida Supreme Court sanctioned the feeding tube to be removed on 31 of March 2005 in spite of opposition from President George Bush and the Congress but she died on 31 of March 2005. Terri’s case resonated with other cases that obviously influenced the Supreme Court’s decision to have the feeding tube removed, which included, the case of â€Å"Karen Quinlan Ann in 1976,† â€Å"Paul Brophy in 1986,† and â€Å"Nancy Cruzan in 1990† in which the patients who didn’t have written advance directives. In all these cases, the courts viewed the freedom and privacy interest of the patients as supreme and thus, the judge argued that she would not hav e wished to continue living under life-prolonging measures all her life hence sanctioned the that the feeding tube be remove from her (Perry, Churchill and Kirshner, 2005) A number of legal considerations were put into perspective in the determination of this case. Firstly, she had not made any healthcare directive other than private conversations with her

Health and Women as Healers in the African American Culture Research Paper

Health and Women as Healers in the African American Culture - Research Paper Example African Americans have a long health tradition and practices of health that shape what they do to care for themselves today. According to Becker, Rahima, and Edwina (par. 9), the traditional medicine of African Americans can be traced back past enslavement in America to their native cultures in Africa. Fundamental facets of the African American culture are key self-care strategy development. There is a basic self-care approach that builds on extensive values and practices. These practices and values comprise of social support, spirituality and traditional medicine. Each of these practices of culture is vital in shaping the understanding of an individual of self-care. Together, they form the foundation for the activities of self-care that are cultured further so as to manage illnesses. Nonetheless, when the cultural approach to self-care was applied to particular health concerns, the establishment of additional self-care strategies was impacted by access to health care. Health care accessibility made a difference in how individuals managed their illnesses Healing has a long alliance with faith, spirit, family support and altered consciousness state. Women have traditionally been healers in the society in all cultures, as healing has been viewed as the natural duty of wives and mothers. Healing has also been regarded as a natural display of the feminine principle. Healing is the return toward the integrity natural state and individual wholeness. Healers facilitate the process of healing. The woman healer learns or inherits skills and abilities of healing from family, apprenticeships or spirits. The woman healer can holistically observe the intricate nature of the illness. Then, she treats the mind, body and spirit with stress in the spirit and practice prevention of disease. Moreover, their clients trust them. These women have a distinct connection to the spirit world that empowers them to heal. Additionally, they are wise to

(GC Instrument Experiment) Determination of Ethanol Concentration in Lab Report

(GC Instrument Experiment) Determination of Ethanol Concentration in Biological Fluids using Gas Chromatography - Lab Report Example The BAC level in all 50 states of the US is set by law at 0.08% w/v a value, which is much higher in comparison to other countries. Other countries have BAC limits of 0.03% w/v or even less (International Center for Alcohol Policies). The use of gas-liquid chromatography in the modern science has eliminated the complex nature of the matrix affecting the analysis of ethanol in blood previously (Jones and Pounder 12). The sample size employed in gas-liquid chromatography is also small hence making the method convenient for analysis of small samples. In gas chromatography, the gaseous mobile phase, which is referred to as the carrier gas, conveys the analyte in the column (Harris 528). Mostly, inert gas such as helium and nitrogen are used as mobile phase while non-polar liquids such as polyethylene glycol can be used as stationary liquid phase (Harris 528). Separation is founded on the dispersal of the analytes between the mobile and stationary phases. The analyte concentration in the gas phase affects its elution since high analyte concentration means more time is spent in the mobile phase as well as the stationary phase (Colin 19). Short analysis time and high precision make it a method of choice. A comparison between flame ionization detectors (FID) and electron capture detectors (ECD) shows that FIDs are highly sensitive to almost all organic compounds, have a wide linear response range that surpasses 107, have low maintenance requirements and are less expensive to acquire and operate compared to ECDs (Harris 543). Five ethanol standards were prepared in a 20 mL gas-tight vial by mixing ca. 0.5% w/w ethanol and ca. 0.5% w/w of tert-butanol in water. The table below summarizes the preparation. tert-Butanol was used as the internal standard. A Shimadzu 14A GC with a flame ionization detector was used. Polyethylene glycol was used as the stationary phase, and the column temperature

Discuss the pros and cons of floating against fixed exchange rate Essay

Discuss the pros and cons of floating against fixed exchange rate regime using the Mundell-Fleming and the Dornbusch models - Essay Example With increased supply of money, people will transform that non interest-bearing asset, money into interest bearing assets, bonds. Therefore, the demand for bonds will rise. That will lead to an increase in bond price. (Obstfeld and Rogoff, 1984) Due to the inverse relationship between bond price and market rate of interest, the market rate of interest will fall. This fall in market rate of interest will be followed by a huge capital outflow. Now, same amount of domestic money will run after less amount of foreign currency resulting in domestic currency depreciation. To maintain the domestic currency at a fixed level, the central bank will have to sell its foreign currency reserve in exchange of domestic money. This phenomenon will lead to a contraction in money supply and it will continue till the market rate of interest rises to its initial level, that is, till the initial expansionary monetary policy gets fully crowded out. (Obstfeld, 2000) From the above, it is clear that the monetary policy will be fully ineffective under fixed exchange rate regime. Now, if the government chooses a fiscal expansion through a rise in government expenditure, then income rises. With a rise in income, transaction demand for money increases. With a rise in transaction demand for money, people will sell bonds in order to meet that increased transaction demand. So, bond supply will rise, bond price will fall and market rate of interest will rise. With the increase in market rate of interest a huge capital inflow will occur, resulting in a currency appreciation. In order to maintain the fixed exchange rate the central bank will purchase that extra supply of foreign exchange. It will result in an increase in money supply, increasing the demand for bond, which will eventually lower the initial rise in interest rate to its initial level. However income will be higher than the initial level. So fiscal policy will

Investigating the effects of mutation on active site amino acids of Lab Report

Investigating the effects of mutation on active site amino acids of beta-lactamase - Lab Report Example Using these two techniques it is possible to synthesize a protein that will bind any desired target. As recent studies suggest, it is possible to add random peptide sequences into loops of ?-lactamase subsequently establishing the catalytic properties of the produced ?-lactamase derivatives. The same authors highlighted the fact that there is no correlation between tolerance to insertion and tolerance to mutagenesis. A turn between two ?-strands next to the active site was found to be inactive in random mutagenesis but demonstrated the opposite in insertions. The present work consists of three elements. Initially it is creating a construct (cloning a mutated gene into an expression vector) ?-lactamase a. using traditional cloning methods (overlapping PCR for mutagenesis, digestion, ligation). Then move on to Protein- Prep- expressing and isolating mutated ?-lactamase a, transformation of construct into competent cells b and protein purification by GFC and IEC before, finally, move on to investigating the effects of mutation on the functionality of ?-lactamase a. Activity assay of mutants compared to those of the WT enzyme A Procedure Week 1: PCR- Primer Design/PCR Mutagenesis Two sterile 0.2 ml PCR tubes were loaded with 5 Â µL PFU buffer, 3 Â µL dNSO, 2.5 Â µL template, 0.5 Â µL PFU, 26.5 Â µL H2O each. Also, one tube was loaded with 5 Â µL Reverse Primer and 5 Â µL Forward Primer Mutant while the other was loaded with 5 Â µL Forward Primer and 5 Â µL Reverse Primer Mutant. 23 cycles of PCR were used to generate the required amount of the DNA sequence of interest. Denaturation, annealing, and elongation represent one cycle of PCR. The first minute of DNA generation was conducted at 950C the second at 500C. The temperature for the following three minutes was raised to 720C with subsequent 10 minutes of elongation at 720C before finally cooling down to 40C affording the crude product. Week 2: PCR Fragment Purification and Restriction Digest A. The crude product produced on the previous stage was loaded into the wells of 0.4 % agarose gel, the first run was conducted. All bends were cut and 330 Â µL QG buffer was added. The mixture was heat till the gel dissolved completely after that transferred to the column and span for 2 minutes. 500 Â µL QG buffer was added and spinning was continued for extra three minutes. 30 Â µL EB buffer was added to dissolve DNA and spinning was continued for 2 minutes. In this way DNA was pulled through. B. To generate the required amount of DNA PCR was conducted. Each of the two sterile 0.2 ml PCR tubes were loaded with 5 Â µL PFU buffer, 5 Â µL Forward Primers, 5 Â µL Reverse Primers, 2.5 Â µLdNTP, 0.5 Â µL pfu, Â µL H2O. Also, one tube was additionally loaded with 5 Â µL AB DNA (Forward mutant) while the other 5 Â µL CD DNA (reverse mutant). On the next day the first tube was loaded with DNA 30 Â µL, Eco R1 buffer 4 Â µL, Eco R1 - 1 Â µL, Hind III- 1 Â µL, H2O- 4 Â µL and the second w ith 4 Â µL vector, Eco R1 buffer 4 Â µL, Eco R1- 1 Â µL, Hind III- 1 Â µL, H2O- 4 Â µL. Both tubes were left at 370C overnight. Week 3: Restriction Fragment Purification/Ligation/Agar Plate Preparation The gel run was initiated following purification of the previously generated DNA samples. DNA concentration was measured and was found to be 5 Â µL into 500 Â µL. The following ligation was conducted. The ratio PCR/Vector was 3/1 Week 4: DNA Transformation/
