wave equation is an important second-order linear partial differential equation for the description of waves – as they occur in physics – such as sound waves‚ light waves and water waves. It arises in fields like acoustics‚ electromagnetic‚ and fluid dynamics. Historically‚ the problem of a vibrating string such as that of a musical instrument was studied by Jean le Rond d’Alembert‚ Leonhard Euler‚ Daniel Bernoulli‚ and Joseph-Louis Lagrange.

process of distillation. Distillation is the separation of volatile substances mixed with nonvolatile substances by boiling the mixture to alter the phase of the volatile substance. The researchers used the simple distillation set up to conduct the experiment. 25 ml of The Bar Vodka was used and 7 ml of distillate was collected before a temperature of 95 degrees Celsius was reached. Collected distillate was then subjected to a flammability test to confirm ethanol content. The percent ethanol was computed

“Human error versus human capability: Which way should the pendulum swing?” Human factors can be defined as “the technology concerned to optimize the relationship between people and their activities by the systematic application of the human sciences‚ integrated within the framework of system engineering” (Edwards‚ 1988‚ p. 9). Human factors have evolved over the years since the birth of tools many millennia ago (Civil Aviation Authority‚ 2002). The modern evolution of human factors happened in

Medication errors are among the biggest issues in health care settings today. The effect of managed care is one of the causative factors. The need to contain costs has invariably doubled the nurses ’ workload making them less efficient as caregivers. Example of problem is the high incidence of medication errors. Nurses ’ workload has increased tremendously regardless of the fact that most of these patients are of great acuity‚ thereby predisposing them to a greater risk of medication errors. Medication

Errors of overregularization is a common error that Marcus (1996) proposes to stem from the existence of mental rules denoted by the acquisition of a rule‚ the lexicon store through memory of past tense forms and the an irregularity always is superior to the acquired rule. The paper states four types of evidence where overregularization may not be explained by the draw towards regular stem-past pairs. In analyzing this piece of literature‚ we have to be aware of the limitations of this paper. The
