NEDU
The United States Navy Experimental Diving Unit (NEDU or NAVXDIVINGU) is the primary source of diving and hyperbaric operational guidance for the US Navy. It is located within the Naval Support Activity Panama City in Panama City Beach, Bay County, Florida. Purpose The functions of the Navy Experimental Diving Unit are to test and evaluate diving, hyperbaric, and other life-support systems and procedures, and to conduct research and development in biomedical and environmental physiology. NEDU also provides technical recommendations to the Naval Sea Systems Command to support operational requirements of the US armed forces. History Brooklyn Navy Yard Experimental diving in the US Navy started in 1912 at the Brooklyn Navy Yard under the leadership of Chief Gunner George D. Stillson. Stillson's research program ultimately led to increasing diver capabilities from to over of depth based on Haldane's decompression work with the Royal Navy. This resulted in the first pub ...

(August 8, 1903 – January 16, 1992) was an American physician, who was principally responsible for developing the U.S. Naval Medical Research Institute. Behnke separated the symptoms of Arterial Gas Embolism (AGE) from those of decompression sickness and suggested the use of oxygen in Recompression chamber, recompression therapy. Behnke is also known as the "modern-day father" of human body composition for his work in developing the Hydrostatic weighing, hydrodensitometry method of measuring body density, his standard man and woman models as well as a somatogram based on Anthropometry, anthropometric measurements. Early life Behnke was born August 8, 1903, in Chicago, Illinois. He moved to New Mexico and settled in Whittier, California, by 1912.

Naval Support Activity Panama City
Naval Support Activity Panama City (NSA PC), is a military shore installation of the United States Navy located in Bay County, just outside Panama City, Florida. Among its various tenant commands, it houses the Naval Surface Warfare Center Panama City Division (NSWC PCD), the Center for Explosive Ordnance Disposal & Diving (CENEODDIVE), the Navy Experimental Diving Unit (NEDU), and Coast Guard Station Panama City. History The NSA PC was founded as the U.S. Navy Mine Countermeasures Station on 20 July 1945, as a result of the transfer of the test station from Solomons, Maryland, but was renamed ca. 1955 to the U.S. Navy Mine Defense Laboratory. In 1972, it was renamed the Naval Coastal Systems Laboratory which changed to Naval Coastal Systems Center in 1981. The base has been a subsidiary of several other commands in the past including Naval Surface Warfare Center Carderock Division, and Naval Surface Warfare Center Dahlgren Division, under which it was designated Naval Surfa ...

Naval Sea Systems Command
The Naval Sea Systems Command (NAVSEA) is the largest of the United States Navy's five "systems commands," or materiel (not to be confused with "material") organizations. From a physical perspective, NAVSEA has four shipyards for shipbuilding, conversion, and repair, ten "warfare centers" (two undersea and eight surface), the NAVSEA headquarters, located at the Washington Navy Yard, in Washington D.C., and other locations in 15 states and 3 overseas continents. NAVSEA's primary objective is to engineer, build, buy, and maintain the U.S. Navy's fleet of ships and its combat systems. NAVSEA's budget of almost $30 billion accounts for nearly one quarter of the Navy's entire budget, with more than 80,200 personnel and 150 acquisition programs under its oversight. History The origin of NAVSEA dates to 1794, when Commodore John Barry was charged to oversee the construction of a 44-gun frigate and ensure that all business "harmonized and conformed" to the public's interest.

Commercial Diving
Commercial diving may be considered an application of professional diving where the diver engages in underwater work for industrial, construction, engineering, maintenance or other commercial purposes which are similar to work done out of the water, and where the diving is usually secondary to the work. In some legislation, commercial diving is defined as any diving done by an employee as part of their job, and for legal purposes this may include scientific, public safety, media, and military diving. That is similar to the definition for professional diving, but in those cases the difference is in the status of the diver within the organisation of the diving contractor. This distinction may not exist in other jurisdictions. In South Africa, any person who dives under the control and instructions of another person within the scope of the Occupational Health and Safety Act, 1993, is within the scope of the Diving Regulations, 2009.

Helium
Helium (from el, ἥλιος, helios, lit=sun) is a chemical element with the symbol He and atomic number 2. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas and the first in the noble gas group in the periodic table. Its boiling and melting point are the lowest among all the elements. It is the second lightest and second most abundant element in the observable universe (hydrogen is the lightest and most abundant). It is present at about 24% of the total elemental mass, which is more than 12 times the mass of all the heavier elements combined. Its abundance is similar to this in both the Sun and in Jupiter, due to the very high nuclear binding energy (per nucleon) of helium-4, with respect to the next three elements after helium. This helium-4 binding energy also accounts for why it is a product of both nuclear fusion and radioactive decay. The most common isotope of helium in the universe is helium-4, the vast majority of which was formed during t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
