Osteosarcoma
An osteosarcoma (OS) or osteogenic sarcoma (OGS) (or simply bone cancer) is a cancerous tumor in a bone. Specifically, it is an aggressive malignant neoplasm that arises from primitive transformed cells of mesenchymal origin (and thus a sarcoma) and that exhibits osteoblastic differentiation and produces malignant osteoid. Osteosarcoma is the most common histological form of primary bone sarcoma. It is most prevalent in teenagers and young adults. Signs and symptoms Many patients first complain of pain that may be worse at night, may be intermittent and of varying intensity and may have been occurring for a long time. Teenagers who are active in sports often complain of pain in the lower femur, or immediately below the knee. If the tumor is large, it can present as overt localised swelling. Sometimes a sudden fracture is the first symptom because the affected bone is not as strong as normal bone and may fracture abnormally with minor trauma. In cases of more deep-seated tumors t ...

Open Scripting Architecture
AppleScript is a scripting language created by Apple Inc. that facilitates automated control over scriptable Mac applications. First introduced in System 7, it is currently included in all versions of macOS as part of a package of system automation tools. The term "AppleScript" may refer to the language itself, to an individual script written in the language, or, informally, to the macOS Open Scripting Architecture that underlies the language. Overview AppleScript is primarily a scripting language developed by Apple to do inter-application communication (IAC) using Apple events. AppleScript is related to, but different from, Apple events. Apple events are designed to exchange data between and control other applications in order to automate repetitive tasks. AppleScript has some processing abilities of its own, in addition to sending and receiving Apple events to applications. AppleScript can do basic calculations and text processing, and is extensible, allowing the use of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
9K33 Osa
The 9K33 ''Osa'' (, literally "wasp"; NATO reporting name SA-8 ''Gecko'') is a highly mobile, low-altitude, short-range tactical surface-to-air missile system developed in the Soviet Union in the 1960s and fielded in 1972. Its export version name is Romb. Development Design work on an entirely new, self-propelled air defense guided missile system began in 1960 and was assigned to the Moscow-based () research and design institute under lead designer M.M. Kosichkin. The program initially suffered numerous delays and setbacks due to poorly formulated performance and tactical requirements, as this was a pioneering battlefield air defense system with no equivalents in existence at the time, and no doctrinal experience with such a weapon. P.M. Chukadov was assigned project leader in 1965 after a thorough review of the stalled program. The Osa had service acceptance in 1972 after a period of trials. Description The Osa was the first mobile air defense missile system incorporating it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ontario Society Of Artists
The Ontario Society of Artists (OSA) was founded in 1872. It is Canada's oldest continuously operating professional art society. When it was founded at the home of John Arthur Fraser, seven artists were present. Besides Fraser himself, Marmaduke Matthews, and Thomas Mower Martin were there, among others. Charlotte Schreiber was the first woman member in 1876 and showed work in the Society's Annual show of that year. The list of objectives drawn up by the founding executive included the "fostering of Original Art in the province, the holding of Annual Exhibitions, the formation of an Art Library and Museum and School of Art". Prominent businessman William Holmes Howland was invited to be President of the Society. Fostering art The OSA, in its early years, had a major effect on the development of art in Ontario, if not in Canada. Its annual shows were reviewed regularly by major Toronto newspapers and the development of its artists and their work was followed in detail. For instance ...

M79 Osa
The M79 Osa ( sr, Оса; "wasp") is a Yugoslav-made portable 90 mm anti-tank weapon made of fibre-reinforced plastics. It resembles the French portable anti-tank launcher 89 mm LRAC F1. It consists of the launcher, a CN-6 sighting piece, rocket and carrying case for the rocket. The M79 shoots unguided projectiles in direct sight and is effective against armoured fighting vehicles and fortifications. Operation The M79 Osa is operated by a two-man team, an operator and a loader. The loader inserts the rocket container through the rear of the launcher. The operator then takes aim at the target through the CN-6 sight. The CN-6 sight has 3.5x magnification and a 10 degree field of view. It also features anti-laser filters to protect the operator from blinding battlefield lasers. When the trigger is pressed, the rocket motor is fired electronically. The rocket leaves the launcher at a speed of approximately 250 meters per second. It is accurate enough to be used against a ...

Obstructive Sleep Apnea
Obstructive sleep apnea (OSA) is the most common sleep-related breathing disorder and is characterized by recurrent episodes of complete or partial obstruction of the upper airway leading to reduced or absent breathing during sleep. These episodes are termed "apneas" with complete or near-complete cessation of breathing, or "hypopneas" when the reduction in breathing is partial. In either case, a fall in blood oxygen saturation, a disruption in sleep, or both may result. A high frequency of apneas or hypopneas during sleep may interfere with restorative sleep, whichin combination with disturbances in blood oxygenationis thought to contribute to negative consequences to health and quality of life. The terms obstructive sleep apnea syndrome (OSAS) or obstructive sleep apnea–hypopnea syndrome (OSAHS) may be used to refer to OSA when it is associated with symptoms during the daytime (e.g. excessive daytime sleepiness, decreased cognitive function). Most individuals with OSA are un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Osa (handgun)
The PB-4 Osa (russian: ПБ-4 «ОСА», "wasp"), is a family of Russian non-lethal pistols that can be also used as a flare gun, a flashbang gun or a starting pistol. The system consists of the pistol (2-4 cartridges, laser target pointer, electronic ignition capsule), and various ammunition types. The Osa was developed in the 1990s by G.A. Bideev. It was designed and is manufactured by the state-owned Federal Center for Research and Manufacturing and the Institute for Science and Research in Applied Chemistry. The pistol is available in the civilian market. Design details The PB-4 is a four-barreled break-action gun. It has two horizontal "8"-shaped chambers in its aluminum chamber block, each housing two rounds. There is no need for a separate chamber for each round, because the gas pressure is contained by the cartridges' thick cylindrical case (the external case diameter is 18mm, while the bullet caliber is 15.3mm). This design aims to prevent the gun from operating proper ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
