DRDC Toronto
DRDC Toronto is a major military research station located at the former site of CFB Downsview in Toronto, Ontario, Canada. It is one of several centres making up Defence Research and Development Canada (DRDC). History The Centre's roots go back to 1939 when the Department of National Defence (DND) recognized the vital importance of human factors in the ability of Canada's armed forces to safeguard the nation in peacetime and at war. Recognizing the importance of aviation medicine to defence, an inter-departmental committee, the Associate Committee on Aviation Medical Research, was established in June, 1939, chaired by Sir Frederick Banting. Laboratory studies in pressure physiology began in the Banting and Best Institute, University of Toronto, where the first decompression chamber for human studies in Canada was set up. To expand the effort, in 1940, the No.1 Clinical Investigation Unit (No1 CIU) was formed at the former Eglinton Hunt Club at 1107 Avenue Road with the construc ...

Research Station
Research stations are facilities where scientific investigation, collection, analysis and experimentation occurs. A research station is a facility that is built for the purpose of conducting scientific research. There are also many types of research stations including: biological field stations, space stations etc. Research station sites might include remote areas of the world, oceans, as well as outer space, such as the International Space Station. Biological research stations developed during a time of European colonization and imperialism where naturalists were employed to conduct observations on fauna and flora. Today, the discipline is represented by a number of organizations which span across multiple continents. Some examples include: the Organization of Biological Field Stations and the Organization for Tropical Studies. Space stations were also developed over a number of decades through scientific analysis and writing, with the first design aspects of early space stat ...

Oran
Oran ( ar, وَهران, Wahrān) is a major coastal city located in the north-west of Algeria. It is considered the second most important city of Algeria after the capital Algiers, due to its population and commercial, industrial, and cultural importance. It is west-south-west from Algiers. The total population of the city was 803,329 in 2008, while the metropolitan area has a population of approximately 1,500,000 making it the second-largest city in Algeria. Etymology The word ''Wahran'' comes from the Berber expression ''wa - iharan'' (place of lions). A locally popular legend tells that in the period around AD 900, there were sightings of Barbary lion, Barbary lions in the area. The last two lions were killed on a mountain near Oran, and it became known as ''la montagne des lions'' ("The Mountain of Lions"). Two giant lion statues stand in front of Oran's city hall, symbolizing the city. History Overview During the Roman Empire, a small settlement called ''Unica Colonia'' ...

Human Factors
Human factors and ergonomics (commonly referred to as human factors) is the application of psychological and physiological principles to the engineering and design of products, processes, and systems. Four primary goals of human factors learning are to reduce human error, increase productivity, and enhance safety, system availability, and comfort with a specific focus on the interaction between the human and the engineered system. The field is a combination of numerous disciplines, such as psychology, sociology, engineering, biomechanics, industrial design, physiology, anthropometry, interaction design, visual design, user experience, and user interface design. Human factors research employs methods and approaches from these and other knowledge disciplines to study human behavior and generate data relevant to the four primary goals above. In studying and sharing learning on the design of equipment, devices, and processes that fit the human body and its cognitive abilities, the ...

Science, Technology And Society
Science and technology studies (STS) is an interdisciplinary field that examines the creation, development, and consequences of science and technology in their historical, cultural, and social contexts. History Like most interdisciplinary fields of study, STS emerged from the confluence of a variety of disciplines and disciplinary subfields, all of which had developed an interest—typically, during the 1960s or 1970s—in viewing science and technology as socially embedded enterprises. The key disciplinary components of STS took shape independently, beginning in the 1960s, and developed in isolation from each other well into the 1980s, although Ludwik Fleck's (1935) monograph ''Genesis and Development of a Scientific Fact'' anticipated many of STS's key themes. In the 1970s Elting E. Morison founded the STS program at Massachusetts Institute of Technology (MIT), which served as a model. By 2011, 111 STS research centers and academic programs were counted worldwide. Key theme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Security
National security, or national defence, is the security and defence of a sovereign state, including its citizens, economy, and institutions, which is regarded as a duty of government. Originally conceived as protection against military attack, national security is widely understood to include also non-military dimensions, including the security from terrorism, minimization of crime, economic security, energy security, environmental security, food security, and cyber-security. Similarly, national security risks include, in addition to the actions of other nation states, action by violent non-state actors, by narcotic cartels, and by multinational corporations, and also the effects of natural disasters. Governments rely on a range of measures, including political, economic, and military power, as well as diplomacy, to safeguard the security of a nation state. They may also act to build the conditions of security regionally and internationally by reducing transnational caus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hyperbaric Medicine
Hyperbaric medicine is medical treatment in which an ambient pressure greater than sea level atmospheric pressure is a necessary component. The treatment comprises hyperbaric oxygen therapy (HBOT), the medical use of oxygen at an ambient pressure higher than atmospheric pressure, and therapeutic recompression for decompression illness, intended to reduce the injurious effects of systemic gas bubbles by physically reducing their size and providing improved conditions for elimination of bubbles and excess dissolved gas. The equipment required for hyperbaric oxygen treatment consists of a pressure chamber, which may be of rigid or flexible construction, and a means of delivering 100% oxygen. Operation is performed to a predetermined schedule by trained personnel who monitor the patient and may adjust the schedule as required. HBOT found early use in the treatment of decompression sickness, and has also shown great effectiveness in treating conditions such as gas gangrene and carbon mo ...

Hypobaric Chamber
A hypobaric chamber, or altitude chamber, is a chamber used during aerospace or high terrestrial altitude research or training to simulate the effects of high altitude on the human body, especially hypoxia (low oxygen) and hypobaria (low ambient air pressure). Some chambers also control for temperature and relative humidity. Procedure One or more subjects (usually, pilots or crew members, though anyone interested in the effects of high altitude can usually arrange a visit) are placed in the chamber. Before "ascending" to the desired altitude, subjects breathe oxygen from oxygen masks to purge nitrogen from their bloodstream so decompression sickness (DCS) does not occur. With masks in place, the atmospheric pressure inside the chamber is then reduced to simulate altitudes of up to tens of thousands of feet. The subjects then remove their oxygen masks and experience the symptoms of hypoxia. An inside safety observer, breathing oxygen by mask, should always be present to pla ...

Environment Chamber
An environmental chamber, also called a climatic chamber or climate chamber, is an enclosure used to test the effects of specified environmental conditions on biological items, industrial products, materials, and electronic devices and components. Such a chamber can be used: # as a stand-alone test for environmental effects on test specimens # as preparation of test specimens for further physical tests or chemical tests # as environmental conditions for conducting testing of specimens Overview An environmental test chamber artificially replicates conditions which machinery, materials, devices or components might be exposed to. It is also used to accelerate the effects of exposure to the environment, sometimes at conditions not actually expected. Chamber testing involves testing and exposing products to various environmental conditions in a controlled setting. Climatic Chamber testing and Thermal Shock testing are part of chamber testing. Climatic Chamber testing is a broad c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Centrifuge
A centrifuge is a device that uses centrifugal force to separate various components of a fluid. This is achieved by spinning the fluid at high speed within a container, thereby separating fluids of different densities (e.g. cream from milk) or liquids from solids. It works by causing denser substances and particles to move outward in the radial direction. At the same time, objects that are less dense are displaced and moved to the centre. In a laboratory centrifuge that uses sample tubes, the radial acceleration causes denser particles to settle to the bottom of the tube, while low-density substances rise to the top. A centrifuge can be a very effective filter that separates contaminants from the main body of fluid. Industrial scale centrifuges are commonly used in manufacturing and waste processing to sediment suspended solids, or to separate immiscible liquids. An example is the cream separator found in dairies. Very high speed centrifuges and ultracentrifuges able to provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canadian Forces
} The Canadian Armed Forces (CAF; french: Forces armées canadiennes, ''FAC'') are the unified military forces of Canada, including sea, land, and air elements referred to as the Royal Canadian Navy, Canadian Army, and Royal Canadian Air Force. Personnel may belong to either the Regular Force or the Reserve Force, which has four sub-components: the Primary Reserve, Supplementary Reserve, Cadet Organizations Administration and Training Service, and the Canadian Rangers. Under the '' National Defence Act'', the Canadian Armed Forces are an entity separate and distinct from the Department of National Defence (the federal government department responsible for administration and formation of defence policy), which also exists as the civilian support system for the Forces. The Canadian Armed Forces are a professional volunteer force that consists of approximately 68,000 active personnel and 27,000 reserve personnel, increasing to 71,500 and 30,000 respectively under "Strong, Secure ...

Downsview, Ontario
Downsview is a neighbourhood in the north end of Toronto, Ontario, Canada, located in the district of North York. The area takes its name from the Downs View farm established around 1842 near the present-day intersection of Keele Street and Wilson Avenue. It now extends beyond the intersection of Sheppard Avenue and Dufferin Street (the latter which is bypassed by Allen Road in the vicinity of the intersection), though it is popularly seen as including the areas to the north right up to the Toronto city limit at Steeles Avenue. The area includes several large post-World War II subdivisions. Within the area is Downsview Airport, the former site of Canadian Forces Base Downsview, which has since been largely converted following the end of the Cold War into an urban park known as Downsview Park. The airport is still used as a manufacturing and testing facility for Bombardier Aerospace. Description From the east side of Dufferin Street to areas to the east, the area is primarily r ...

Occupational Safety And Health
Occupational safety and health (OSH), also commonly referred to as occupational health and safety (OHS), occupational health, or occupational safety, is a multidisciplinary field concerned with the safety, health, and welfare of people at work (i.e. in an occupation). These terms also refer to the goals of this field, so their use in the sense of this article was originally an abbreviation of ''occupational safety and health program/department'' etc. The goal of an occupational safety and health program is to foster a safe and healthy occupational environment. OSH also protects all the general public who may be affected by the occupational environment.Fanning, Fred E. (2003). Basic Safety Administration: A Handbook for the New Safety Specialist, Chicago: American Society of Safety Engineers Globally, more than 2.78 million people die annually as a result of workplace-related accidents or diseases, corresponding to one death every fifteen seconds.
