Introduction

Sentinel events occur unexpectedly within the working areas. When this event occurs, they can lead to serious injuries or deaths at a time. The injuries can be physical or psychological depending on the extent of injury (Valentin et al. 2006). However, the Joint Commission defines sentinel event as any unexpected incident in the health care sector, which can end in demise or solemn physical or mental damage to the patient in place. Nevertheless, sentinel events are not in any case related to the natural sickness of the patient neither the illness result into the occurrence of sentinel events. The ...

What does the margin of error tell us about a sample taken from a large population? How does the confidence level for a sample outcome differ from the sample’s margin of error? The margin of error is a numerical value that expresses or estimates the likelihood of error in an experiment’s results. Thus, it can somehow account for the statistical significance of a result. If it is smaller, then the likelihood of error is also small, making the results more credible. Smaller sample sizes from a large population generally have a larger margin of error while larger ...

Introduction:

Corrosion refers to the partial and gradual dissolution of materials used in water treatment and supply systems, pumps, pipes, tanks and valves. In most circumstances, almost all water is corrosive and this may lead to structural failure, water leaks, capacity losses and deterioration of the microbial and chemical water quality (WHO 2011). The pipes used in water distribution are made of different materials such as plastic, metals (galvanized steel, copper, lead and iron), and even concrete. Pipes made from concrete and plastic tend to be corrosion resistant. In piping systems, however, there are several water quality factors working singly ...
