AISI316L Stainless steels (SS) are widely used in biomedical industries to produce orthopedic implants‚ screws‚ cardiovascular stents and other surgery devices because of their proper mechanical properties and corrosion resistance at low cost [1–5]. However‚ they have represented some premature damages when utilized in the body environment. This sort of steels is susceptible to pitting corrosion and release of Ni‚ Mo and Cr ions in body environment which can intensify the risk of cancer and inflammatory

Guns‚ Germs‚ and Steel Assignment From the beginning‚ the Europeans had an advantage over the Native Americans. They had the horses and the guns. Guns played a major role in the success of the Europeans. Guns not only aided in overthrowing the Native Americans‚ but also aided in keeping the Europeans alive by allowing them to hunt and gather food. Horses also played a huge role. They made battle and travel easier. Over time‚ the use of animals began advancing. Animals provided warmth and tools

If you think animal testing is okay in any way shape or form‚ imagine you as a dog‚ rat‚ or any other animal getting tested on and harmed or even killed by the product that was tested on you? You would not want or like that one but. So why are we making actual animals suffer? Because we just need them? Because they are our only source of testing? There are many different ways of testing that do not involve animals

Solid state physics II Testing a Peltier Element Abstract The purpose of the experiment was to investigate the cooling properties of a Peltier element and specifically the relation between the electric current through the element and the temperature in a refrigerator cooled by the element. The “refrigerator” consisted of a cavity in a block of polystyrene foam with the Peltier element covering the opening of the cavity. A fan on top

2.9 Erbium Doped Fiber Laser The EDFLs can operate in several wave-length regions‚ ranging from visible to far infrared. The 1.55 region has attracted the most attention because it coincides with the low-loss region of silica fibers used for optical-communications [14]. The erbium absorption line that best matches with available high power pump diodes is in the 980 regime. At this wave-length‚ the absorption cross section of erbium is so low that an excessive amount of fiber would be required for
