MP-448 Skyph
The MP-448 ''Skyph'' (MP-448 '' Скиф'') is a Russian pistol. History The MP-448 was developed during the late 1990s by engineer-constructor and weapon designer Dmitry Bogdanov. It was initially offered by Izhevsk Mechanical Plant (IzhMech) for export sales and for private security companies as an enhanced version of the famous Makarov PM pistol (which is also manufactured by IzhMech). In November 2000 one MP-448 pistol and one MP-448C pistol were presented at "INTERPOLITEX-2000" Arms exhibition in Moscow, they were offered for export.Юрий Амелин.

Semi-automatic Pistol
A semi-automatic pistol is a type of repeating single-chamber handgun ( pistol) that automatically cycles its action to insert the subsequent cartridge into the chamber (self-loading), but requires manual actuation of the trigger to actually discharge the following shot. As a result, only one round of ammunition is fired each time the trigger is pulled, as the pistol's fire control group disconnects the trigger mechanism from the firing pin/ striker until the trigger has been released and reset. Additional terms sometimes used as synonyms for a semi-automatic pistol are self-loading pistol, autopistol, autoloading pistol, and automatic pistol (E.G.: Automatic Colt Pistol). A semi-automatic pistol recycles part of the energy released by the propellant combustion to move its bolt, which is usually housed inside the slide. After a round of ammunition is fired, the spent cartridge casing is extracted and ejected as the slide/bolt moves rearwards under recoil, the hammer/s ...

Gram
The gram (originally gramme; SI unit symbol g) is a Physical unit, unit of mass in the International System of Units (SI) equal to one one thousandth of a kilogram. Originally defined as of 1795 as "the absolute weight of a volume of pure water equal to Cube (algebra), the cube of the hundredth part of a metre [1 Cubic centimetre, cm3], and at Melting point of water, the temperature of Melting point, melting ice", the defining temperature (~0 °C) was later changed to 4 °C, the temperature of maximum density of water. However, by the late 19th century, there was an effort to make the Base unit (measurement), base unit the kilogram and the gram a derived unit. In 1960, the new International System of Units defined a ''gram'' as one one-thousandth of a kilogram (i.e., one gram is Scientific notation, 1×10−3 kg). The kilogram, 2019 redefinition of the SI base units, as of 2019, is defined by the International Bureau of Weights and Measures from the fixed numeric ...

Semi-automatic Pistols Of Russia
Semi-automatic - ''Noun'': "Partially automatic and partially manual in operation (i.e., operated both automatically and manually, by hand); not ''fully-automatic''." This may refer to: * A semi-automatic firearm, a firearm which automatically loads the next round, but will only fire one round per trigger pull ** Semi-automatic rifle ** Semi-automatic pistol ** Semi-automatic shotgun * Semiautomatic switching system, a term used in telecommunication * Semi-automatic transmission: a manual transmission with an automated clutch (i.e., no physical clutch pedal), but the driver is still required to shift gears manually, by hand. Also called: ''clutchless manual transmission'' or ''automated manual transmission''. * "Semi-Automatic", a song from Twenty One Pilots' 2013 album '' Vessel'' [Baidu] |

Mikhail Kalashnikov
Mikhail Timofeyevich Kalashnikov ( rus, Михаи́л Тимофе́евич Кала́шников, p=kɐˈlaʂnʲɪkəf; 10 November 1919 – 23 December 2013) was a Soviet and Russian lieutenant general, inventor, military engineer, writer, and small arms designer. He is most famous for developing the AK-47 assault rifle and its improvements, the AKM and AK-74, as well as the PK machine gun and RPK light machine gun. Kalashnikov was, according to himself, a self-taught tinkerer who combined innate mechanical skills with the study of weaponry to design arms that achieved battlefield ubiquity. Even though Kalashnikov felt sorrow at the weapons' uncontrolled distribution, he took pride in his inventions and in their reputation for reliability, emphasizing that his rifle is "a weapon of defense" and "not a weapon for offense". Early life Kalashnikov was born in the village of Kurya, in present-day Altai Krai, Russia, as the seventeenth child of the 19 children of Aleksandra F ...

Private Security Company
A private security company (PSC) is a business entity which provides armed or unarmed security services and expertise to clients in the private or public sectors. Overview Private security companies are defined by the U.S. Bureau of Labor Statistics as companies primarily engaged in providing guard and patrol services, such as bodyguard, guard dog, parking security and security guard services. Many of them will even provide advanced special operations services if the client demands it. Examples of services provided by these companies include the prevention of unauthorized activity or entry, traffic regulation, access control, and fire and theft prevention and detection. These services can be broadly described as the protection of personnel and/or assets. Other security services such as roving patrol, bodyguard, and guard dog services are also included, but are a very small portion of the industry. During the COVID-19 pandemic, some security companies engaged in vaccine supply c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ergonomics
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, t ...

Blowback Operation
Blowback is a system of operation for self-loading firearms that obtains energy from the motion of the cartridge case as it is pushed to the rear by expanding gas created by the ignition of the propellant charge. Several blowback systems exist within this broad principle of operation, each distinguished by the methods used to control bolt movement. In most actions that use blowback operation, the breech is not locked mechanically at the time of firing: the inertia of the bolt and recoil , relative to the weight of the bullet, delay opening of the breech until the bullet has left the barrel. A few locked breech designs use a form of blowback (example: primer actuation) to perform the unlocking function. The blowback principle may be considered a simplified form of gas operation, since the cartridge case behaves like a piston driven by the powder gases. Other operating principles for self-loading firearms include delayed blowback, blow forward, gas operation, and recoil operation. ...

Pounds Per Square Inch
The pound per square inch or, more accurately, pound-force per square inch (symbol: lbf/in2; abbreviation: psi) is a unit of pressure or of stress based on avoirdupois units. It is the pressure resulting from a force of one pound-force applied to an area of one square inch. In SI units, 1 psi is approximately equal to 6895 Pa. Pounds per square inch absolute (psia) is used to make it clear that the pressure is relative to a vacuum rather than the ambient atmospheric pressure. Since atmospheric pressure at sea level is around , this will be added to any pressure reading made in air at sea level. The converse is pounds per square inch gauge (psig), indicating that the pressure is relative to atmospheric pressure. For example, a bicycle tire pumped up to 65 psig in a local atmospheric pressure at sea level (14.7 psi) will have a pressure of 79.7 psia (14.7 psi + 65 psi). When gauge pressure is referenced to something other than ambient atmospheric pressure, then the u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
