Performing a maintenance task on one of our aircraft, we notice a very clear and visible scratch down to the bare metal. This type of scratch must be reported and should have been as soon as it happened, in order to prevent costly corrosion. It was no doubt a member of our shops who caused the damage but failed to report it. We brought it up to our Lead Petty Officer knowing it was the right thing to do, only to be met with a simple shoulder shrug and the comment of “why would we tell…

end of the 21st century (Gregory, 2013). A mere 0.5m rise will place over 2 billion people worldwide at risk. This is an estimate of 37% of the population within a 60-mile radius of the coast, at a direct or indirect risk of being affected by the corrosion of landmass (Ireland, n.d.). The quantity of assets at risk from being below a 1:100 flood by the end of the century with just a 0.3m rise in sea levels could stand between 17-180 trillion (Hinkel et al,…

Animal testing is the use of any non-human animal in an experiment. It has become more prevalent in the past few decades due to advancements in the medical and scientific fields. Without these experiments, we would not have many of the…

1. “You leading others to achieve a goal” is how the Coast Guard defines leadership. My personal definition adds to those concise words only by acknowledging that the quality with which one leads is vital. A goal can be achieved with brute force or with finesse.

Throughout my 23 years in the Coast Guard, I have been exposed to a wide range of leadership styles and philosophies. Some leaders demonstrated great…

alkalinity of a water give us an valuable information that is used in the practice since this parameter is widely useful in various aspects of environmental engineering. The alkalinity results can be used in chemical coagulation, water softening, corrosion control, buffer capacity control and industrial waste. Alkalinity has little public health significance. Highly alkaline water usually unpalatable and consumer tend to seek other supplies (8). The four methods performed afford us determine…

processed food or body products or in human bodies, meaning that the general public is already exposed or utilizing many of the chemicals used in a well. These chemicals are used for numerous processes including limiting bacterial growth, preventing corrosion of the castings, breaking down minerals, suspension, pH balancers, and maintaining viscosity ("What Chemicals are Used"). Fracking fluid is not used for the intention of harming the environment, but instead, is to prevent any unnatural or…
