...Master Diver Diving Equipment Open circuit demand scuba is the most commonly used by recreational divers, but closed circuit and semi-closed rebreathers are now available. Test Pressure: the pressure to which the cylinder is subjected to during hydrostatic testing. For a 200 bar cylinder it is 300 bars, for a 232 bar cylinder it is 348 bars. If internal inspection reveals corrosion, it may have to be cleaned by tumbling. The tumbling process involves filling the cylinder approximately half full of an abrasive material such as carbide chips, or aluminum oxide chips, and rotating it for a number of hours. A dual valve for a single cylinder, known as a Y-valve, or an H-valve, allows a diver to mount 2 regulator systems on a single cylinder. The first stage reduces cylinder pressure to an intermediate pressure (or low pressure) of approximately 90-150 psi (6 to 10 bar). The second stage reduces the intermediate (low) pressure to ambient pressure. Because of their tendency to fail in a closed position, upstream valves are rare in modern scuba regulators. In a Balanced Valve regulator the operation of the regulator is independent of the cylinder or applied pressure. (Breathes the same at low tank pressure) The internal valves of scuba regulator first stages are available in 2 basic types, diaphragm and piston. The main valve of a Pilot Valve regulator is opened and closed with air pressure, rather than mechanical leverage. Some regulators may...

...career of a commercial diver entitles doing all sorts of different jobs, such as repair or salvage, while submerged in water. People who are extremely comfortable being underwater and like the metal business would love this job. The conditions divers would be in is, outside and underwater the majority of the time. While working, the time will matter since customers want to be in the water. Divers could be located anywhere they need repairs or salvage including world-wide or even close to home. A divers morning routine is to wake up and start gearing up for the day, as well as a daily inspection of all gear to make sure it’s in perfect working condition. This career will start at 50 thousand in a year, but the potential year salary is upwards of 250k dollars a year. Unlike pipefitters, divers are submerged so the pipefitters can earn upwards of 100k a year. In this decade the jobs in the commercial diver career are dropping.

...Problématique : Coral Divers Resort (CDR) est une entreprise évoluant dans l’industrie de la plongée sous-marine dans le sud-ouest des Bahamas. Malgré le fait qu’entre 1989 et 2001 le marché ait présenté une croissance stable de 10 % par année en terme de plongeurs certifiés, cette entreprise est maintenant en difficulté financière et semble avoir atteint la saturation. La demande de l’organisation est devenue stagnante et l’entreprise enregistre des pertes depuis quelques années en raison de la baisse de ses revenus et de la faible diminution de ses coûts depuis 3 ans. Nous estimons que l’une des raisons de la dégringolade de CDR est liée à la concurrence accrue dans son secteur d’activité et dans sa région géographique. Également, même si nous pouvons dire que l’offre d’un service sécuritaire et le haut niveau de compétence des employés composent la compétence fondamentale de CDR, cette dernière n’est pas difficile à imiter, ainsi, l’entreprise ne possède plus un avantage concurrentiel durable. Qui plus est, son modèle d’affaires ne lui permet pas de se différencier de ses compétiteurs. En effet, la proposition de valeur offerte par CDR est plus faible que ses concurrents situés à Nassau où l’ambiance est plus touristique. D’autre part, en plus des déficits des 2 dernières années, CDR n’est plus en mesure d’augmenter ses revenus ni sa part de marché. Afin d’assurer la survie de son entreprise, M.Greywell devra examiner de près les trois niveaux de sa stratégie. En ce qui concerne...

...Compare and Contrast: Jay Gatsby and Dick Diver Griffin Gilmore Mrs. Clark Humanities 28 November 2012 In the novels Great Gatsby and Tender is the Night by Scott Fitzgerald the two main characters, Jay and Dick both face problems in achieving their dreams and face much adversity trying to achieve it. In both novels pursuing their dreams leads to their demise due to their failure to realize that success is from within, not from the superficial qualities that the society around them looks up to. The first difference between Gatsby and Dick is how they value money. Jay Gatsby believes that with money he can buy his happiness, he plans on using his money to fall in love with him and have her leave her current husband (Tom) to be with himself. Dick on the other hand doesn't like all the wealth of Nicole and trues to distance himself way from it. When Nicole and himself start out they are living off of his few thousand a year. Nicole's parents then buy them their own clinic. Much like Gatsby his wealth by no means that he is happy. “had wedded a desire for money to an essentially unacquisitive nature … he had never felt more sure of himself … than at the time of his marriage to Nicole. Yet he has been swallowed up like a gigolo, and somehow permitted his arsenal to be locked up in the Warren safety deposit vaults.” This just goes to show how even with their almost endless income, they were not satisfied, which properly illustrates the time period which took place then,...

...Health Promotion Among Diverse Populations Shannon Tumblin Grand Canyon University Family-Centered Health Promotion NRS-429V Denice Gibson February 22, 2015 Health Promotion Among Diverse Populations A person’s culture often delineates an individual or a group of individuals that have shared values, religious preferences, languages and lifestyles. Culture is typically passed from one generation to the next while lifestyle choices and tradition are picked up along the way. These choices have a great impact on the ability to live a healthy life. While there are many ethnic groups residing in the United States today, Hispanics have this highest number of residents with a sixty percent increase from 1990 to 2000. The United States is expected to populate up to 97 million Hispanics by the year 2050 which will account for approximately one-quarter of the U.S. population. (Escarce, 2002) The words Hispanic and Latino have a tendency to be used interchangeably here in the United States with regard to Spanish-speaking countries such as Mexico, Brazil and Costa Rica. The remainder of this paper will elaborate on the health promotion of the diverse population of Hispanics in the United States as well as the disparities and barriers associated with the health of these residents. Current Health Status of the Hispanic Population The health status of the Hispanic population, according to several government studies, is quite favorable in relation to other U.S. ethnic groups...

Bean, Sears, IBM, and the World Bank. The impetus for the Work- Out was the belief by GE’s CEO that the company’s culture was too bureaucratic and slow to respond to change. He wanted to create a vehicle that would effectively engage and empower GE workers. Essentially, Work-Out brings together employees and managers from many different functions and levels within an organization for an informal 3-day meeting to discuss and solve problems that have been identified by employees or senior management. Set into small teams, people are encouraged to challenge prevailing assumptions about “the way we have always done things” and develop recommendations for significant improvements in organizational processes. The Work-Out teams then present their recommendations to a senior manager in a public gathering called a Town Meeting. At the town Meeting, the manager in charge oversees a discussion about the recommendation and then is required to 4 The Institute reserves the right to conduct a separate Viva exam on telephone, as a part of the student's exam in case the Subject Lecturer recommends it in any particular student’s case. make a yes-or-no decision on the spot.

...diving experience, which was unheard of before the invention of the rebreather. By controlling and maintaining the partial pressure of the gasses, one breathes at depth, thus restricting the nitrogen loaded into his or her system. After the dive, the circulatory system is cleaner than when the diver entered the water. The air all humans breathe contains 21% oxygen, 79% nitrogen, and slight trace gases. Circulatory systems maintain these averages. However, when using a rebreather, it changes these parameters to 45% oxygen and 55% nitrogen at a prescribed depth. Imagine the consequences; divers will no longer have a "NO-FLY" restriction after diving, so the long- anticipated diving vacation can be enjoyed right up to the time the flight leaves. The only thing that stands between them and experiencing the Closed Circuit Rebreather diving vacation is training. Closed Circuit Rebreather Closed circuit rebreathers will revolutionize the dive industry. Individuals will experience a longer, more comfortable diving experience, with safety features that can eliminate nitrogen narcosis when diving within recreational limits. Before the invention of the rebreather, all divers experienced nitrogen narcosis in some form. The latest evolution to be introduced into the Self Contained Underwater Breathing...

The owner of the coral diving resort, Jonathan Greywell with his promotional strategy had been enhanced by the resort (Beamish & Neupert, 2008). According to the case study “Coral Divers Resort (Revised)” (Beamish & Neupert, 2008), over the years, Greywell had established a solid reputation for the Coral Divers Resort as a safe and knowledgeable scuba diving resort. Coral Diver Resort offered not only a divers wild renege selection of diving activities, but also a beachfront location. As a small well regarded all round dive resort in the Bahamas, however, many divers had come to prefer coral diving resort over the other crowded tourists resort in the Caribbean" (Beamish & Neupert, 2008). However, Greywell was able to found this niche by creating short weekend and mid-week diving ventures, which was a service that attracted the public. Furthermore, Coral Divers Resort has targeted both the aficionado divers and the tyro; as a matter of fact, both of them want maximum diving pleasure at a minimum expense. Jonathan Greywell, the owner of a small scuba diving operation in the Bahamas is reassessing his strategic direction in the light of declining revenues (Beamish & Neupert, 2008). Among the changes being considered are shark diving, family diving, exit, and shifting operations to another Caribbean location. The owner...

...Current performance and strategy Overview of current strategy, structure and performance Coral Divers Resort, located in a small but quiet island, has been a safe and knowledgeable scuba diving resort with solid reputation over the past ten years. Its current strategy is to provide not only a wonderful place for diving, but an ideal beachfront location. For ten years’ operations, Coral Divers’ annual revenues are as high as $554,000. However, situations get worse reflected directly by continually declining revenues. Critical issues, key decisions, opportunities and challenges The biggest issue for Coral Divers is the lack of specialized features to distinguish itself from the competition. From Greywell’s perspective, Coral Divers has not provided any different services in aspect of diving or resort. Accordingly, Greywell has proposed three main choices to improve the current dilemma. As families are a growing market segment, engaging in family diving vacations would be a feasible solution, with the aid of Rascals in Parades; a travel company specialized in family diving vacations. Another potential strategy is to develop adventure diving. Although associated with threats that other resorts in the Bahamas also offer adventure-oriented dives, Coral Divers Resort enjoys natural underwater attractions such as Shark Wall and Shark Buoy, which are popular and close to Coral Divers. The final option is to leave New Province and relocate elsewhere. But he is still wondering whether...

...The Risks of Scuba Diving The Risks of Scuba Diving Western Governors University The Risks of Scuba Diving The Risks of Scuba Diving Scuba diving is a very popular sport, but a lot of amateurs are not aware of the risks they might face during or after a dive. Every year, 15 million divers engage in 250 million dives worldwide. Thanks to advanced technology and awareness training, accidents can be either prevented or minimized. Unfortunately, the biggest threat to divers is the divers themselves. Hastiness (“I don't have time to check the equipment, it will be alright...”,) proudness and group pressure (“Come on, let's dive even deeper...”,) or simply underestimating one's physical limits can often lead to injuries, or in some unfortunate cases even fatalities. This article will review the various risks that divers might face under the water's surface or after ascent back to the main land. Although scuba diving is considered a high risk sport, this article is intended to spark some interest and to encourage the reader to take more interest in the magnificent and amazing world of scuba diving. Medical risks Cardiovascular incidents One of the major causes for fatalities is drowning. There are different issues that can lead to drowning. A lot of those issues have one common denominator: cardiovascular incidents. Looking at statistics of the general population, it does not come as a big surprise that also under water one of the biggest risks, which lead to cardiovascular...

...various risks that need to be considered while scuba diving. It discusses in great detail and very accurate the medical issues that divers can potentially face not only during the activity, but also days after the action. Although this article uses a lot of medical terms, it is very useful, because it gives a lot of facts and statistics, which I can incorporate into my presentation. Without going into medical details, I will also be able to use his examples about health concerns. Dr. Peter Germonpré, MD, is the Medical Director of the Centre for Hyperbaric Oxygen Therapy of the Belgian Armed Forces, as well as Medical Director of the Divers Alert Network, and has treated numerous divers, who suffered from injuries during their dives. He is also active in research projects and has published several research articles about diving injuries. This article has been written mainly for medical professionals, similar to a lot of other sources, which I have been using during my research. Hilchey, T. (1995, June 6). Risks to Spine Seen in Scuba Diving. New York Times. Tim Hilchey discusses an article by Dr. Jurgen Reul, who examined the brains, spinal cords, and spines of amateur divers and compared the results to those of nondivers. He concluded that amateur divers are at a higher risk to suffer from nervous system lesions than professional divers or nondivers. I can use this article to add another important risk of diving to my presentation. Although Dr. Reul was writing his article...

...Lynn Divers thought she had heard the worst of it when doctors told her that her daughter Alyssa had cancer. But the diagnosis was only the first in a series of emotional bombshells: Alyssa’s cancer, osteosarcoma, is rare, and in her case, aggressive, requiring a cocktail of different chemotherapy drugs. She didn’t respond well to the first regimen that doctors tried, which led to their adding three other punishing medications to her treatment. Because of the chemotherapy, Alyssa’s kidneys were in danger of failing, so she would need nightly infusions of phosphorous to keep her organs functioning. Then came the truly heartbreaking news. In late February, when Divers called the hospital to confirm Alyssa’s upcoming chemotherapy treatment, the nurse informed her that there was a drug shortage. The hospital couldn’t be sure that there would be enough methotrexate — the cornerstone of therapy for some childhood cancers, including leukemia and osteosarcoma — to treat Alyssa, now 10. Divers was told she might have to reschedule the session; the hospital would let her know. “It made me sick to my stomach to hear that,” says Divers, a former chaplain from Palmyra, Va. “Alyssa was in treatment for over a year already, and the last thing you want to do is add unnecessary delays in treatment, which gives the cancer a chance to catch up.” Divers explains that her daughter’s cancer doubles in tumor load every 34 days, “so you need to hit it again and again to eradicate it.” The story...
