Clear! The physics behind the electrical life savers, defibrillators “Defibrillation has become an integral part of the emergency response routine. In fact, the American Heart Association considers defibrillation a basic life support skill for paramedics and rescue workers.” (DIRECT QUOTE) The human heart is arguably the most vital organ of the human body, as its coordinated and controlled two-part pumping is necessary to supply blood to the entire body. This supply rate is regulated by the…

Machining of GFRP laminate materials is difficult due to their anisotropic and non homogeneity in nature which consist of distinctly different phases, their response to machining. Machining of composite materials is rarely avoided in view of losing the strength of components due to interlayer fracture and delamination damage. In specific situations where metal inserts are inevitable in case of joining or affixing with other mating part, in this situation milling and drilling operations can’t be…

Nurse executives (NE) face endless ethical issues and challenges in today’s healthcare environment in efforts to improve the delivery of quality patient care. The objective of the paper is to include a focus on the NEs role in patient safety and how pay for performance and reimbursement are established on clinical outcomes. Furthermore, concentration will be placed on the influence the institute of medicine (IOM) has on the significance of a culture of safety. Finally, discussion of how the…

Reflection High-Energy Electron Refraction Intensity Oscillations Reflection high-energy electron refraction (RHEED) has been used as a surface probe for in situ observation of monolayer growth using molecular beam epitaxy (MBE) because of its high surface sensitivity and a near grazing incidence. It utilizes diffraction of electrons by surface atoms[1] and the RHEED intensity oscillation can convey morphological information of the growth surface if the intensity oscillation pattern is properly…

After the epidemic of the Revolutionary War, the thirteen colonies of the United States of America yearned to form a government that would essentially replace the British system. The first attempt of restitution began with the Founding Fathers’ and their deliverance of the Articles of Confederation. The Articles of Confederation was “a written agreement ratified in 1781 by the thirteen original states; it provided a legal symbol of their union by giving the central government no coercive power…

Elements above the atomic number 95 are produced in a particle accelerator by accelerating a small charged nuclei (such as Helium, Boron or Carbon) in a particle accelerator to combine with a heavy nucleus (often of a previously made transuranic element) target. The transuranic elements have short half-lives as the atomic number increases. The smaller nuclei combines within the target nucleus, creating a new unstable nuclide or radioactive isotope. The high speeds are required to overcome the…

Engineering Design Project: “Bread Maker” Introduction to the Project Parker (2017) claims that bread makers are highly controversial kitchen units. Most critics declare that the loaves produced by the existing commercially available brands often resemble self-kneaded bread. Notwithstanding, this appliances tend to cut down considerable effort and time needed to produce a sufficient quantity of home-made loaves. Worth noting, the pieces of bread produced are cheaper than those sold in commercial…

wingspan of 125 feet fit into a 16 by 20 foot initial impact hole” (911 Blogger), wouldn’t there be some damage from the wings hitting the pentagon, the wings wouldn’t disintegrate on impact because there was not enough time, it’s made out of aluminum alloy which a strong metal. This attack on the pentagon seems more of a cover up than an attack. After the incident and further investigation on the pentagon the damages given do not related to the damages estimated by the size of the plane. Could…

After his return to England, in 1941 Fuchs was invited by Rudolf Peierls, another German-born British physicist, to Birmingham to work on the British nuclear weapon project, codenamed Tube Alloys. While there were concerns regarding the security of hiring Fuchs, good scientists were in such short demand that Britain decided that Fuchs was worth the risk. He was cleared by MI5 and also by the Department of Scientific and Industrial Research for this position. This decision was later criticized in…
