Primary mission of archives: institutional versus collecting approach effects
Archives serve as historical repositories for organizations. They offer organization and security for information - including documents, files, photos, manuscripts and other reference material - that may have significance for future use or the operations of the institution. This paper examines how archivists can structure practices in ways that relate to the over-arching mission. Paper length is 5 pages.
Marijuana Shouldn't Be Legalized
Introduction
Physical Health Concerns
According to a Harvard University Law School document, it would be "…fallacious to conclude that because the chemicals in marijuana have been found to present fewer dangers…" than cocaine, heroin, alcohol and tobacco, that the recreational use of marijuana "is safe" (Harvard). In fact, even though many states authorize the use of cannabis for medical purposes (for AIDS sufferers and for those experiencing harmful side effects from cancer chemotherapy and glaucoma), marijuana has "potentially dangerous side effects" (Harvard).
Those "dangerous [physical] side effects" include: a) damage to cells in the bronchial passages that could cause chronic bronchitis; b) a decrease in the ability of the body's immune cells to "fight off fungi, bacteria, and tumor cells"; c) the possibility of getting "pulmonary infections and respiratory cancer"; and d) since one joint of powerful cannabis has "four times more tar than a cigarette," lungs are exposed to the same dangers that cigarettes create (Harvard).
History of Ultrasound of Physics and the Properties of the Transducer
Physics – History of Ultrasound Physics and Properties of Transducer
Ultrasound Physics developed from discoveries made by many professions from numerous countries over several centuries. At first, the discoveries were not related to medicine and were made by scientists in several other fields. However, as these discoveries were gradually combined, health care professionals began to see the usefulness of ultrasound physics for detection, diagnosis and treatment of many ailments. One constant in the history of ultrasound physics is the transducer, which converts energy to an image, and is still used in various forms, depending on the depth of the object to be imaged. The continued refinement of transducers and of Ultrasound Physics in general shows how valuable Ultrasound Physics is to the medical profession and to humanity. Though Ultrasound Physics will continue to develop, the current state of the art is so well-developed that ultrasound can now be accomplished in remote locations in real time with iPhones.
