Prescription, Nonprescription, and Herbal Medication Research Paper

Prescription, Nonprescription, and Herbal Medication - Research Paper Example As the essay declares the aging process is defined by numerous impairments of several regulatory processes that play a critical role in cells and organs. In addition, other physiological changes are evident in advanced age, and have the capacity to affect the absorption, distribution, metabolism, and excretion of drugs. The geriatric population exhibits cardiac dysfunctions. The relaxation and contraction of heart muscles change remarkably a one ages. Blood flow becomes slower, a factor that may affect drug distribution. In addition, aging brings about the reduction of renal mass. Fewer nephrons define the reduction of renal mass. According to the research findings there is a notable delay in the kidney functions, a factor that affects the elimination of drugs. The gastrointestinal system is also affected by aging because elderly people have lower rates of hydrochloric acid and pepsin. Research has highlighted that aging may contribute to potential changes in the enzyme secreting cells or hormonal glands a factor that minimizes the efficiency of the gastrointestinal system. In the small intestines, absorption of some substances reduces with age, while in the colon, the transit time may prove to be slower. Other digestive enzymes such as lipase and trypsin usually decrease as one age. The liver is a critical organ in the metabolism of drugs. With advancing age comes a remarkable reduction in the liver blood flow. In other cases, the liver structure may change over time while enzymes may cease to function effectively.

Five Essay Questions-Operations Management Assignment

Five Essay Questions-Operations Management - Assignment Example That is the only way an organization can get its resulting products and services to the right market and in the right manner while considering the time and cost aspects of the processes. It is through the knowledge of OM that an organization develops its innovation towards competitive advantages, which exist inextricably alongside processes. The processes range from the use of emerging and appropriate technology to the use of existing resources to create new ones and new values. It is only when operations are managed in ways that create the notion of differentiation that such processes lead to organizational success (Chase, Jacobs & Aquilano, 2007). CPM/PERT analyzes the tasks involved in a certain project in terms of the required time to complete each. The use of CPM/PERT techniques for managing projects is founded on the concept that a certain set of critical activities that constitute the longest path through the network of activities will control the entire project. The identification of the critical activities is important because they can then be assigned to responsible teams, allowing the management resources to be used optimally by concentrating on the key activities that determine the entire project’s fate. As a statistical tool, its design is intended to map, schedule and manage complex projects and analytically represent the necessary tasks to complete a project, employing time as the variable reflecting planned performance specifications. Advantages of CPM/PERT techniques include defining dependencies and making them visible and also potentially reducing project duration. This is possible because precedence r elationships between the structures of work breakdown are better understood, facilitating the potential to reduce a project’s lifecycle. However, the disadvantage is that individual dependency relationships can
