Lab Report Discussion Sample

Lab Report Discussion Paper We have made four set-ups in two different specimens. Onion and Boat of Moses skin with water, 2%, 5% and 10% salt (NCAA) Solution. Based on our experiment, the result of the set up explains that the presence of the salt solution results in outward diffusion of water and the collapse of the protoplasm. In table 1, we have observed under the microscope that the onionskin mounted with water has no results of polymerase cell (0%). This time, we have repeated the procedure with 2% salt solution and it is observed that there are 6 (3. 9%) localized cells. In the 5% salt solution, there are 119 (87. %) polymerase cells. And in the 10% salt solution, there are number of polymerase cells present. In table 2,same procedure was done but with different specimen. We have observed that the boat of Moses mounted with water also has no results of polymerase cell (0%). In the 2% salt solution, there are about 20 (43. 4%) polymerase cells. 46 (88. 5%). Polymerase cells were also observed in the set-u p with 5% salt solution and in the solution, all of the 59 cells are polymerase (100%). Thus, increase in percentage of the salt in a solution also increases the number of the polymerase cells. Water passes out of the cell towards a region of lesser water concentration which results to the shrinkage of the protoplasm (Figure 1). This shrinkage away from the cell wall due to excessive loss of water is called polynomials. Figure 1. Polynomials in Ilium Cheap : The first image in the left shows that the cells mounted with water shows no signs of polynomials, in the middle mounted with 2% NCAA solution shows minimal shrinkage of cells, in the right most image mounted with 5% NCAA solution almost all of the cells were polymerase. After observing the onion and boat of Moses skin in the different solution, we have replaced the solution with distilled water. Based on our observation, when the solution is replaced, the protoplasm regained to its original form simply because of the vacuole that absorbs and stores the water. This then results to the inward diffusion of water. If after a short time, however, the polymerase cells are transferred from the salt solution to pure water, the direction of the et water movement is reversed, for there is now relatively more water outside the cells than there is inside.

Oh My Aching Back Essay examples Oh My Aching Back Essay examples Oh My Aching Back: Low Back Pain in the Adult Population Allyson Pfeil Bond University 22/10/2014 13357540 â€Å"Lower back pain is a major burden to society† that â€Å"many people will experience during their life† (Tulder, Koes & Bombardier, 2002, p.761). In Australia, â€Å"Eighty-percent of Australians experience lower back pain [with] ten-percent [resulting in] disability† (Briggs & Buchbinder, 2009, p.499). With such a high prevalence of low back pain in adults, it is recognized as one of Australia’s â€Å"major health and socioeconomic problems† (Tulder, Koes, & Bombardier, 2002, p.761). This major problem has caught the attention of the National Health Priority Area (NHPA) and they have set up guidelines for Australians on how to manage low back pain. Although â€Å"ninety-five percent of cases [doctors are unable to] pinpoint the cause of the pain,† it is â€Å"not necessary to know the [origin] in order to deal with the pain effectively† (NHMRC, 2003, p.1). Lower back pain (LBP) can be defined as â€Å"pain, muscle tension, or stiffness localized below the costal margin and above the inferior gluteal folds, with or without leg pain.† (Tulder, Koes † becoming the â€Å"second [highest] cause of activity limitation in [the] adult [population]† (Loney meaning that the cause of the symptoms are unknown (Tulder, Koes & Bombardier, 2002, p.762). While lower back pain causes the majority of the Australian adult population physical agony, it causes the Australian government significant financial pain. â€Å"Low back pain is associated with high indirect and direct costs [of] heath care utilization, work absenteeism, and disablement† (Tulder, Koes with an overall cost of† 9.17 billion† (Walker, Muller & Grant, 2003, p.79). â€Å"Ninety-percent of the indirect costs are due to work absenteeism and disablement,† with employers financing â€Å"three to four months of sick leave† (Tulder, Koes & Bombardier, 2002, p.769). This massive amount of money being expended on a preventable health condition represents a â€Å"huge health problem with a significant economic burden† that needs to be addressed promptly and properly, to reduce the enormous suffering and related high costs (Walker, Muller & Grant, 2003, p.79). Predominantly the indirect costs of LBP are work related; therefore the individuals’

Management and Organisational Behaviour - Essay Example These require organizational redesign which is meant to improve organizational effectiveness and the ability to adapt to a constantly changing environment (Douglas, 1999). Two different approaches explain work motivation – the content theories and the process theories (Analoui, 2000). The content theories explain what actually motivates people to work. As per Maslow’s Hierarchy of Needs the basic physiological needs have to satisfied only after which an individual clamours for other needs such as safety needs, need for love, self-esteem or self-actualization. According to Herzberg an employee’s motivation to work is understood when the employee’s attitude to work is understood (Tietjen & Myers, 1998). The attitude of employees depends on two sets of factors – those that generate happy feelings within the worker and hence were task-related and those that give rise to unhappiness but are not task-related. These are directly related to the job but to the conditions surrounding the job. The first sets of factors that give happiness are called motivators which include recognition, achievement, career progression, responsi bility and work itself. Motivation is intrinsic and comes from within. Intrinsic motivation has also been referred to in the self-determination theory (SDT), as the tendency to seek out challenges and novelty. Ryan and Deci (2000) contend that â€Å"motivation produces†. Intrinsic motivation requires autonomy because controlled approaches can stifle innovation. These are the esteem needs as specified by Maslow. An employee derives feelings of self-worth, accomplishment and pleasure as the use of his skills provide him with intrinsic rewards (Gallagher & Einhorn, 1976). As one need is satisfied, he strives for the satisfaction of other needs and this motivates or influences his behaviour. Motivators create positive attitude towards job and satisfies the employees need for self-actualization which is
