Rear Admiral (Australia)
Rear admiral (abbreviated as RADM) is the third-highest active rank of the Royal Australian Navy and was created as a direct equivalent of the British rank of rear admiral. It is a two-star rank. Rear admiral is a higher rank than commodore, but lower than vice admiral. Rear admiral is the equivalent of air vice-marshal in the Royal Australian Air Force and major general in the Australian Army. Since the mid-1990s, the insignia of a Royal Australian Navy vice admiral is the Crown of St. Edward above a crossed sabre and baton, above two silver stars, above the word "AUSTRALIA". The stars have eight points as in the equivalent Royal Navy insignia. Prior to 1995, the RAN shoulder board was identical to the UK shoulder board. The UK shoulder board changed in 2001. Rear Admiral Robyn Walker became the first female admiral in the Royal Australian Navy when she was appointed Surgeon-General of the Australian Defence Force on 16 December 2011.

Asbestos
Asbestos ( ) is a group of naturally occurring, Toxicity, toxic, carcinogenic and fibrous silicate minerals. There are six types, all of which are composed of long and thin fibrous Crystal habit, crystals, each fibre (particulate with length substantially greater than width) being composed of many microscopic "fibrils" that can be released into the atmosphere by Abrasion (mechanical), abrasion and other processes. Inhalation of asbestos fibres can lead to various dangerous lung conditions, including mesothelioma, asbestosis, and lung cancer. As a result of these health effects, asbestos is considered a serious Health hazard, health and safety hazard. Archaeological studies have found evidence of asbestos being used as far back as the Stone Age to strengthen ceramic pots, but large-scale mining began at the end of the 19th century when manufacturers and builders began using asbestos for its desirable physical properties. Asbestos is an excellent Thermal insulation, thermal and In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lung Cancer
Lung cancer, also known as lung carcinoma, is a malignant tumor that begins in the lung. Lung cancer is caused by genetic damage to the DNA of cells in the airways, often caused by cigarette smoking or inhaling damaging chemicals. Damaged airway cells gain the ability to multiply unchecked, causing the growth of a tumor. Without treatment, tumors spread throughout the lung, damaging lung function. Eventually lung tumors metastasize, spreading to other parts of the body. Early lung cancer often has no symptoms and can only be detected by medical imaging. As the cancer progresses, most people experience nonspecific respiratory problems: coughing, shortness of breath, or chest pain. Other symptoms depend on the location and size of the tumor. Those suspected of having lung cancer typically undergo a series of imaging tests to determine the location and extent of any tumors. Definitive diagnosis of lung cancer requires a biopsy of the suspected tumor be examined by a patholo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pleural
The pleural cavity, or pleural space (or sometimes intrapleural space), is the potential space between the pulmonary pleurae, pleurae of the pleural sac that surrounds each lung. A small amount of serous fluid, serous pleural fluid is maintained in the pleural cavity to enable lubrication between the pleurae, membranes, and also to create a pressure gradient. The serous membrane that covers the surface of the lung is the visceral pleura and is separated from the outer membrane, the parietal pleura, by just the film of pleural fluid in the pleural cavity. The visceral pleura follows the fissures of the lung and the root of the lung structures. The parietal pleura is attached to the mediastinum, the upper surface of the thoracic diaphragm, diaphragm, and to the inside of the ribcage. Structure In humans, the left and right lungs are completely separated by the mediastinum, and there is no communication between their pleural cavities. Therefore, in cases of a unilateral pneumothor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HMAS Melbourne (R21)
HMAS ''Melbourne'' (R21) was a Majestic-class aircraft carrier, ''Majestic''-class light aircraft carrier operated by the Royal Australian Navy (RAN) from 1955 until 1982, and was the third and final conventional aircraft carrier to serve in the RAN. ''Melbourne'' was the only Commonwealth of Nations, Commonwealth naval vessel to sink two friendly warships in peacetime ship collision, collisions. ''Melbourne'' was laid down for the Royal Navy as the lead ship of the ''Majestic'' class in April 1943, and was launched as HMS ''Majestic'' (R77) in February 1945. At the end of the Second World War, work on the ship was suspended until she was purchased by the RAN in 1947. At the time of purchase, it was decided to incorporate new aircraft carrier technologies into the design, making ''Melbourne'' the third ship to be constructed with an angled flight deck. Delays in construction and integrating the enhancements meant that the carrier was not commissioned until 1955. ''Melbou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HMAS Supply (AO 195)
HMAS ''Supply'' (AO 195) was a of the Royal Fleet Auxiliary (RFA) and the Royal Australian Navy (RAN). Originally named ''Tide Austral'' and intended to be the first ship of a post-World War II Royal Australian Fleet Auxiliary, manpower and financial shortages meant that when the Belfast-built ship was launched in 1955, she could not be accepted into Australian service. Instead, she was loaned to the RFA, operating RFA ''Tide Austral'' (A99). In August 1962, the ship was commissioned directly into the RAN, then renamed a month later to HMAS ''Supply''. ''Supply'' operated as part of the RAN until her decommissioning at the end of 1985. Design, construction, and acquisition In the early 1950s, the RAN considered acquiring a fleet tanker to support their forces.Donohue, ''From Empire Defense to the Long Haul'', p. 106 It was suggested that Australia order a from the United Kingdom (the Royal Navy having ordered three ships of the design), as the backlog of Navy construction in Au ...

The ship was sunk as a target by in June 1999. Images and footage of the ship sinking have been used and adapted for various purposes, including in movies and as propaganda. Construction ''Torrens'' and sister ship were ordered in 1964 as replacements for , a destroyer lost following a collision with the aircraft carrier in 1964. Although intended to be the same as the previous River class ships (themselves based on the British Type 12 frigate), the design was changed from 1965 to incorporate many of the improvements of the British s. Work on the two vessels started without specifications or a contract, and the evolving design meant changes were being made as the ships were being constructed, with resulting delays and cost increases attributed to a lack of planning. ''Torrens'' was laid down by the Cockatoo Docks and E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HMAS Queenborough (G70)
HMAS ''Queenborough'' (G70/D270/F02/57) (originally HMS ''Queenborough'' (G70/D19)) was a Q-class destroyer that served in the Royal Navy (RN) and Royal Australian Navy (RAN).

After the war ended, the ship was transferred on loan to the RAN in exchange for an N-class destroyer, then given to Australia as a gift in 1950. ''Queenborough'' was converted to an anti-submarine frigate, and served with the RAN until 1966. During this time, she was deployed to the Far East Strategic Reserve on multiple occasions, participated in numerous fleet exercises, and took on a partial training role. She was decommissioned and placed in reserve, but reactivated in 1969 as a training ship.

She was built for the Royal Navy and was launched as HMS ''Terrible'' (93) in 1944, but was not completed before the end of World War II. The carrier was sold to Australia in 1947, completed, and commissioned into the RAN as ''Sydney'' in 1948. ''Sydney'' was the first of three conventional aircraft carriers to serve in the RAN, and operated as the navy's flagship during the early part of her career. From late 1951 to early 1952, she operated off the coast of Korea during the Korean War, making her the first carrier owned by a Commonwealth Dominion, and the only carrier in the RAN, to see wartime service. Retasked as a training vessel following the 1955 arrival of her modernised sister ship, , ''Sydney'' remained in service until 1958, when she was placed in reserve as surplus to requirements. The need for a sealift capability saw the ship modified for service as a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
