Sound and visual media - Essay Example Other architectural configurations in arena stages allow for podiums with lifting and dropping abilities. In such cases, the audience often rests on temporary seats that facilitate more flexibility. This configuration allows performers to understand the conditions their viewers are in while performing. Engaging the audience based on these conditions makes the performance better (Condee 9). Better detail and expressiveness is necessary for all production factors (Collins and Kapralos). Even though the audience configuration in an arena stage is raised above the stage, their scenery is often limited to cover optimum lines of sight for viewers on all sides. This condition is different for viewers in a Proscenium Arch Stage whose lines of sight are level before a raised platform. Arena theatres often lack a fly system apart from possibly lighting purposes (Hischak 147). The requirement of giving equal lines of sight for all viewers puts distinct limits on the kind of scenery used and on the activities of the performers. This is because, certain audiences in an arena stage will inevitably be seeing an actor’s back at all times. This configuration allows for good recording and production of sound from real sources. However, certain sounds appear false when produced electronically in an arena theatre. As a result, a surrounding architectural configuration for audience s in an arena call for the building of mechanical instruments that mimic sounds like thunder and rain. Architectural configurations carve up an understanding of the conditions audiences are in through sound reflection (Hischak 147). Sound reflection rare occurs in isolation since sound usually finds a surface on its path where refection is takes place. Knowing the arrangement of audience seats in a theatre is imperative for making predictions of the behavior of sound within that theatre. All surfaces echo and absorb sound to some

Diabetes and Stem Cell Treatment Essay Example | Topics and Well Written Essays - 1000 words

Diabetes and Stem Cell Treatment - Essay Example Stem cells in the treatment of diabetes play a crucial role due to their capabilities in differentiation, in the early stages of development, they can develop into any tissue found in the body ranging from body organs to full body parts (Pileggi, p.1355). Their functionality lies in the way they differentiate into these tissues. To ensure that they can turn into any body tissue their ability must not be lost through the differentiation process. This is because differentiation makes the stem cells into tissue specific cells (Burns et al 438). In diabetes, they are used to regenerate certain parts of the pancreas. To reproduce this vital part that is affected by diabetes, there is a need to modify the stem cells that remain in a patient’s body, in spite of the limited reserves (Holger et al 2). Diabetes is a disease that results from the autoimmune destructions of pancreatic cells that are responsible for an individual’s ability to control and regulate blood glucose (Marko et al 1). Diabetes causes poor blood circulation, heart disease, stroke, infection, kidney failure and sometimes it even results in death (Zhao 2). Due to destruction of these pancreatic cells, the body is unable to produce insulin and thus insulin is administers, however, the role of insulin is to regulate the levels of glucose in the blood of an individual. The destruction of the pancreatic cells responsible for the production of insulin, pancreatic islet B cells, has yet to have a cure. For long periods, scientists have been unable to find a cure as the treatment involves individual approaches that are too complex and expensive. However, in recent times, studies and researches have revealed of a possibility that stem cells can be used to cure or at least reverse diabetic conditions by restarting pancreatic function in an individual and, as a result, eradicate if or
