Science, Technology, Engineering, And Mathematics
Science, technology, engineering, and mathematics (STEM) is an umbrella term used to group together the distinct but related technical disciplines of science, technology, engineering, and mathematics. The term is typically used in the context of education policy or curriculum choices in schools. It has implications for workforce development, national security concerns (as a shortage of STEM-educated citizens can reduce effectiveness in this area), and immigration policy, with regard to admitting foreign students and tech workers. There is no universal agreement on which disciplines are included in STEM; in particular, whether or not the ''science'' in STEM includes social sciences, such as psychology, sociology, economics, and political science. In the United States, these are typically included by the National Science Foundation (NSF), the Department of Labor's O*Net online database for job seekers, and the Department of Homeland Security. In the United Kingdom, the social scien ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MARS-500
The MARS-500 mission was a psychosocial isolation experiment conducted between 2007 and 2011 by Russia, the European Space Agency, and China, in preparation for an unspecified future crewed spaceflight to the planet Mars. The experiment's facility was located at the Russian Academy of Sciences' Institute of Biomedical Problems (IBMP) in Moscow, Russia. Between 2007 and 2011, three different crews of volunteers lived and worked in a mock-up spacecraft at IBMP. The final stage of the experiment, which was intended to simulate a 520-day crewed mission, was conducted by an all-male crew consisting of three Russians (Alexey Sitev, Sukhrob Kamolov, Alexander Smoleevskij), a Frenchman (Romain Charles), an Italian (Diego Urbina), and a Chinese citizen (Yue Wang). The mock-up facility simulated an Earth-Mars shuttle spacecraft, an ascent-descent craft, and the Martian surface. The volunteers who participated in the three stages included professionals with experience in engineering, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Microbiologist
A microbiologist (from Greek ) is a scientist who studies microscopic life forms and processes. This includes study of the growth, interactions and characteristics of microscopic organisms such as bacteria, algae, fungi, and some types of parasites and their vectors. Most microbiologists work in offices and/or research facilities, both in private biotechnology companies and in academia. Most microbiologists specialize in a given topic within microbiology such as bacteriology, parasitology, virology, or immunology. Duties Microbiologists generally work in some way to increase scientific knowledge or to utilise that knowledge in a way that improves outcomes in medicine or some industry. For many microbiologists, this work includes planning and conducting experimental research projects in some kind of laboratory setting. Others may have a more administrative role, supervising scientists and evaluating their results. Microbiologists working in the medical field, such as clini ...

Structural Engineer
Structural engineers analyze, design, plan, and research List of structural elements, structural components and structural systems to achieve design goals and ensure the safety and comfort of users or occupants. Their work takes account mainly of safety, technical, economic, and environmental concerns, but they may also consider aesthetic and social factors. Structural engineering is usually considered a specialty discipline within civil engineering, but it can also be studied in its own right. In the United States, most practicing structural engineers are currently licensed as civil engineers, but the situation varies from state to state. Some states have a separate license for structural engineers who are required to design special or high-risk structures such as schools, hospitals, or skyscrapers. In the United Kingdom, most structural engineers in the building industry are members of the Institution of Structural Engineers or the Institution of Civil Engineers. Typical struct ...

Doctor Of Osteopathic Medicine
Doctor of Osteopathic Medicine (DO or D.O., or in Australia DO USA) is a medical degree conferred by the 38 osteopathic medical schools in the United States. DO and Doctor of Medicine (MD) degrees are equivalent: a DO graduate may become licensed as a physician or surgeon and thus have full medical and surgical practicing rights in all 50 US states. , there were 186,871 osteopathic physicians and medical students in DO programs across the United States. Osteopathic medicine (as defined and regulated in the United States) emerged historically from the quasi-medical practice of osteopathy, but has become a distinct and proper medical profession. , more than 28% of all U.S. medical students were DO students. The curricula at DO-granting medical schools are equivalent to those at MD-granting medical schools, which focus the first two years on the biomedical and clinical sciences, then two years on core clinical training in the clinical specialties. One notable differenc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Doctor Of Medicine
A Doctor of Medicine (abbreviated MD, from the Latin language, Latin ) is a medical degree, the meaning of which varies between different jurisdictions. In the United States, and some other countries, the ''MD'' denotes a professional degree of physician. This generally arose because many in 18th-century medical professions trained in Scotland, which used the MD degree nomenclature. In England, however, Bachelor of Medicine, Bachelor of Surgery (MBBS) was used: in the 19th century, it became the standard in Scotland too. Thus, in the United Kingdom, Republic of Ireland, Ireland and other countries, the MD is a research doctorate, honorary degree, honorary doctorate or applied clinical degree restricted to those who already hold a professional degree (Bachelor's/Master's/Doctoral) in medicine. In those countries, the equivalent professional degree to the North American, and some others' usage of MD is still typically titled Bachelor of Medicine, Bachelor of Surgery. History The fi ...

Airlock
An airlock is a room or compartment which permits passage between environments of differing atmospheric pressure or composition, while minimizing the changing of pressure or composition between the differing environments. An airlock consists of a chamber with two Hermetic seal, airtight doors or openings, usually arranged in series, which do not open simultaneously. Airlocks can be small-scale mechanisms, such as Fermentation lock, those used in fermenting, or larger mechanisms, which often take the form of an antechamber. An airlock may also be used underwater to allow passage between the air environment in a pressure vessel, such as a submarine, and the water environment outside. In such cases the airlock can contain either Atmosphere of Earth, air or water. This is called a floodable airlock or underwater airlock, and is used to prevent water from entering a submersible vessel or underwater habitat. Operation The procedure of entering an airlock from the external or am ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mars Analog Habitat
A Mars analog habitat is one of several historical, existing or proposed research stations designed to simulate the physical and psychological environment of a Martian exploration mission. These habitats are used to study the equipment and techniques that will be used to analyze the surface of Mars during a future crewed mission, and the simulated isolation of the volunteer inhabitants allows scientists to study the medical and psychosocial effects of long-term space missions. They are often constructed in support of extensive Mars analogs (see List of Mars analogs). However, sometimes existing natural places are also valued as Mars analogs. Crewed Mars habitats are featured in most human Mars missions; an alternative may be terraforming or telepresence. The ISS has also been described as a predecessor to Mars expedition. In relation to a Mars habitat, it was noted that they are both essentially closed systems. Scientific motivation Mars analog habitats are established to prep ...

Construction 3D Printing
Construction 3D Printing (c3Dp) or 3D construction Printing (3DCP) refers to various technologies that use 3D printing as a core method to fabricate buildings or construction components. Alternative terms for this process include "additive construction." "3D Concrete" refers to concrete extrusion technologies whereas Autonomous Robotic Construction System (ARCS), large-scale additive manufacturing (LSAM), and Point-to-point construction, freeform construction (FC) refer to other sub-groups. At construction scale, the main 3D-printing methods are extrusion (concrete/cement, wax, foam, polymers), powder bonding (polymer bond, reactive bond, sintering), and additive welding. A number of different approaches have been demonstrated to date, which include on-site and off-site construction, off-site fabrication of buildings and construction components, using industrial robots, gantry crane, gantry systems, and tethered autonomous vehicles.
