Knowing Your Audience ans Communication Release The news of a devastating accident is not easy to prepare or communicate to any one involved. Being the bearer of bad news is never easy. The way in which the news is delivered‚ and what must be done before and after the news is relayed is also important. The needs of the employees is different than the needs of the family members of those men who were trapped in the mine. It is vital to make sure to address each of these groups in a

Introduction: This case study focuses on two mountaineering companies‚ Adventure Consultants and Mountain Madness‚ and what went wrong on May 10‚ 1996‚ when a total of five climbers from these two teams died while on a final summit push on Mount Everest. Even more troubling is the fact that two of these people‚ Rob Hall and Scott Fischer‚ were the leaders of the companies‚ and each had impressive experience on Everest. Many factors combined to create this tragedy‚ including weather‚ varying ability

spectrophotometric analysis of copper sulphate Introduction: In the modern usage. The term spectroscopy includes a large group of techniques which differ widely in their mode of application and information they reveal. As a useful working definition‚ spectroscopy is a study of interaction of electromagnetic radiation with matter in the experiment it means it’s the usage of ultra-light to measure the absorbance of the copper sulpate. The regions of the electromagnetic spectrum immediately adjacent

“The Synthesis of Zinc Chloride”‚ what a peculiar name for a lab that does not even involve synthesis. Synthesis‚ by definition‚ is when two elements are combined in a chemical reaction‚but that is not the case. In this lab we are combining zinc‚ an element‚ and hydrochloric acid‚ a compound‚ but combining a compound and an element is not synthesis‚ it is single replacement. We are taking zinc and hydrochloric acid and making zinc chloride and hydrogen‚ a single replacement‚ but what occurred during

$2.00 a Day: Living on Almost Nothing in America‚ “welfare is dead‚” and the cause is the 1996 welfare reform. While welfare is not actually extinct in theory‚ in practice‚ the number of people benefiting from welfare has decreased significantly‚ while the amount of money being spent has increased‚ proving the ineffectiveness of the current system (Edin‚ Shaefer 2015: 7-9). The changes made to welfare in 1996 has worked against people unable to find or keep reliable work‚ meaning that it is generally

In 1996‚ a number of expedition teams ascended Mount Everest. During May‚ a storm hit Everest‚ causing lives to be lost. This event is now known as the 1996 Mount Everest disaster‚ and it brought changes to mountain climbing. Numerous individuals wrote about the events that occurred during this climb. Among these individuals was Jon Krakauer‚ a writer and member of Rob Hall’s expedition team‚ who provided his account of the events in his book Into Thin Air: A Personal Account of the Mt. Everest Disaster

Mass of Zinc Determination on Galvanized Nails Introduction. In this experiment the mass of zinc on galvanized iron nails was calculated to determine the appropriate price that should be charged to coat a nail with zinc (galvanize) it. The effectiveness of gasometric and gravimetric analysis were assessed by carrying out both methods mathematically using values determined by this experiment‚ and then comparing these values using their percent differences. The mass of zinc found on each nail can
