Managerial Decision Kathy Stamps BUS. 640: Managerial Economics Michael Thirtle March 19‚ 2011 oAbstract Should we buy a new machine or upgrade the old one? One of the managerial decisions that our local hospital had to make was whether to transition into a digital format with our portable x-ray machines by performing transformation upgrades to both existing analog units or to trade them in and use their value to offset the total price incurred by the purchase of new units.

radiograph (XRAY) was taken. The XRAY film is then developed so it can be read by the radiologist; film development requires a technician in a special room with specific equipment and chemicals. The developed film is then physically delivered to‚ and read by‚ a radiologist. Reading the XRAY film generally means the radiologist is on-site (within the hospital‚ clinic or office). If a radiologist is not on-site‚ i.e. after hours or weekends‚ he/she is called in to do the reading. Once the XRAY is read

and Somerville from 1928-1932. she analyzed glass tessellate from Jerash. She decided to do research on X-ray Crystallography. She did a lot of research on crystals and x-rays. Later in her life she became a teacher in chemistry for the women’s college. She became the university reader for x-ray crystallography in 1956. she also worked in the department of mineralogy and crystallography. She continued her research on interesting biological molecules. One of those molecules was insulin. Her research

lab‚ where Watson and Crick did their research and he was the founder of the crystallography. Erwin Chargaff was an Australian born biochemist that discovered the four bases paring of the DNA. Francis Crick who was Watson’s colleague in the discovering the structure of the DNA is described to be very outspoken and bright. Rosalind Franklin also called Rosy was Maurice Wilkin’s assistant who was trained in crystallography. Maurice Wilkins was physicist turned biologist who studied the molecular structure

Perutz also shared important X-ray crystallography imagery with Watson and Crick that he had received from Maurice Wilkins and Franklin. Whether he was supposed to give this information to Watson and Crick without Franklin’s knowledge is unknown‚ nor is it entirely known how important her work was to the discovery of the structure. * Sir Lawrence Bragg – the head of the Cavendish

were chosen? Explain why. The three pieces of equipment; CT scanner‚ Xray and US machine‚ all were in need of replacing. There were three options for each of them in regard to financing. The organization chose to purchase a refurbished CT scanned due to the fact that it has a moderate working life and when it is done the option to upgrade is there. For the Xray machine the organization chose to use a capital lease. Xray machines have a relatively long working life span‚ 15 years generally‚

first year‚ but passed the next (Adler). A few years later‚ after getting out of college‚ Pasteur decided to study in crystallography‚ which soon made him famous (Encyclopedia of Life Sciences). At age 26‚ decided he was tired of studying crystallography and tried a different field: bacteria (Manning 193). Studying bacteria was far more successful than studying crystallography. He had discovered three new types of bacteria: staphylococcus‚ streptococcus‚ and pneumococcus (Dakes 165). He also discovered
