The primary challenge of inhabiting a high salinity environment is balancing osmotic pressure. Since these environments contain high salt concentrations‚ water from the cells of organisms spontaneously diffuses out of the cytoplasm in order to restore osmotic balance. This leaves cells dehydrated and thus‚ eventually causes cell death. In order to ameliorate this predicament‚ halophiles use one of two unique strategies that function to increase the osmolarity of the cell‚ both of which as illustrated

FLUID FLOW UNIT Keywords: Pressure loss‚ straight pipe‚ pipe bend‚ orifice meter‚ venturi meter. 3.1.1. Object The object of this experiment is to investigate the variations in fluid pressure for flow in straight pipes‚ through pipe bends‚ fittings‚ orifice and venturi meters. 3.1.2. Theory When a fluid flows along a pipe‚ friction between the fluid and the pipe wall causes a loss of energy. This energy loss shows itself as a progressive fall in pressure along the pipe and varies with

Prevention of Communicable Diseases Tuberculosis: Infection control strategies: There are three levels of infection control (IC) measures: administrative (managerial)‚ environmental‚ and personal respiratory protection. Administrative controls are the most important since environmental controls and personal respiratory protection will not work in the absence of solid administrative control measures. Each level operates at a different point in the transmission process: • Administrative

Yidi Wang (Joseph) WR 98 Summary of “College Pressures” In the article “College Pressures‚” William Zinsser analysis the four reasons which cost pressures on college students: economic pressure‚ parental pressure‚ peer pressure‚ and self-induced pressure. All college students are under the shadow of these four kinds of pressure. The pressure is so heavy that current college students couldn’t enjoy their college life. Zinsser first cites some messages from a students and the dean to show how

Peer pressure is real. Like a disease it infects the mind and moves into the heart tearing the definition of your original being apart. It has no remorse‚ like a deadly lion on the hunt for prey it marks its weak target carefully and attacks with deadly precision. By definition‚ peer pressure is the strong influence exerted by those who you associate with. Peer pressure starts when kids start growing older and have a sense of the world‚ and an opinion to go with it. Some of us are smart enough to

Physics Tutorial Tonometry for Intra-Ocular Pressure In the linear non-elastic collision of the rod with the eyelid‚ there are 4 notable forces in action (Figure 1). 1. The force (or pressure) of the rod (rod/size of rod) exerted is equal and opposite to the force (or pressure) the cornea re-exerting pressure on the rod. 2. The force (or pressure) required to applanate a constant area of a cornea is equal and opposite to the force (or pressure) of the rebound on the rod exerted by the flattening

committing to the college of their choice are unaware of the peer pressures that arise when one attends school. Many may feel as though peer pressures tend to happen more often when one lives on campus‚ but it can occur off campus too. For example‚ peer pressures can lead to partying‚ drinking and drugs. The want to attend class is a daily pressure because there aren’t any consequences when no attending. Another main college pressure is financial stress. The percentage of partying that goes on throughout

Pressure groups in USA A pressure group is an organised interest group in which members hold similar beliefs and actively pursue ways to influence government. Unlike political parties‚ which seek to win control of government‚ pressure groups are principally interested in influencing those who determine policy. Pressure groups in the US operate at all levels of government be it federal‚ state and local and seek to bring their influence to bear on all three branches of government. There are wide
