Private Company
A privately held company (or simply a private company) is a company whose shares and related rights or obligations are not offered for public subscription or publicly negotiated in the respective listed markets, but rather the company's stock is offered, owned, traded, exchanged privately, or over-the-counter. In the case of a closed corporation, there are a relatively small number of shareholders or company members. Related terms are closely-held corporation, unquoted company, and unlisted company. Though less visible than their publicly traded counterparts, private companies have major importance in the world's economy. In 2008, the 441 largest private companies in the United States accounted for ($1.8 trillion) in revenues and employed 6.2 million people, according to ''Forbes''. In 2005, using a substantially smaller pool size (22.7%) for comparison, the 339 companies on '' Forbes'' survey of closely held U.S. businesses sold a trillion dollars' worth of goods and services ...

Technetium-99
Technetium-99 (99Tc) is an isotope of technetium which decays with a half-life of 211,000 years to stable ruthenium-99, emitting beta particles, but no gamma rays. It is the most significant long-lived fission product of uranium fission, producing the largest fraction of the total long-lived radiation emissions of nuclear waste. Technetium-99 has a fission product yield of 6.0507% for thermal neutron fission of uranium-235. The metastable technetium-99m (99mTc) is a short-lived (half-life about 6 hours) nuclear isomer used in nuclear medicine, produced from molybdenum-99. It decays by isomeric transition to technetium-99, a desirable characteristic, since the very long half-life and type of decay of technetium-99 imposes little further radiation burden on the body. Radiation The weak beta emission is stopped by the walls of laboratory glassware. Soft X-rays are emitted when the beta particles are stopped, but as long as the body is kept more than 30 cm away these should ...

Single-photon Emission Computed Tomography
Single-photon emission computed tomography (SPECT, or less commonly, SPET) is a nuclear medicine tomographic imaging technique using gamma rays. It is very similar to conventional nuclear medicine planar imaging using a gamma camera (that is, scintigraphy), but is able to provide true 3D information. This information is typically presented as cross-sectional slices through the patient, but can be freely reformatted or manipulated as required. The technique needs delivery of a gamma-emitting radioisotope (a radionuclide) into the patient, normally through injection into the bloodstream. On occasion, the radioisotope is a simple soluble dissolved ion, such as an isotope of gallium(III). Most of the time, though, a marker radioisotope is attached to a specific ligand to create a radioligand, whose properties bind it to certain types of tissues. This marriage allows the combination of ligand and radiopharmaceutical to be carried and bound to a place of interest in the body, ...

Positron Emission Tomography
Positron emission tomography (PET) is a functional imaging technique that uses radioactive substances known as radiotracers to visualize and measure changes in metabolic processes, and in other physiological activities including blood flow, regional chemical composition, and absorption. Different tracers are used for various imaging purposes, depending on the target process within the body. For example: * Fluorodeoxyglucose ( 18F">sup>18FDG or FDG) is commonly used to detect cancer; * 18Fodium fluoride">sup>18Fodium fluoride (Na18F) is widely used for detecting bone formation; * Oxygen-15 (15O) is sometimes used to measure blood flow. PET is a common imaging technique, a medical scintillography technique used in nuclear medicine. A radiopharmaceutical – a radioisotope attached to a drug – is injected into the body as a radioactive tracer, tracer. When the radiopharmaceutical undergoes beta plus decay, a positron is emitted, and when the positron interacts with an or ...

Vancouver Sun
The ''Vancouver Sun'', also known as the ''Sun'', is a daily broadsheet newspaper based in Vancouver, British Columbia, Canada. The newspaper is currently published by the Pacific Newspaper Group, a division of Postmedia Network. Published six days a week from Monday to Saturday, the ''Sun'' is the largest newspaper in western Canada by circulation. The newspaper was first published on 12 February 1912. The newspaper expanded in the early 20th century by acquiring other papers, such as the ''Daily News-Advertiser'' and '' The Evening World''. In 1963, the Cromie family sold the majority of its holdings in the ''Sun'' to FP Publications, who later sold the newspaper to Southam Inc. in 1980. The newspaper was taken over by Hollinger Inc. in 1992, and was later sold again to CanWest in 2000. In 2010, the newspaper became part of the Postmedia Network as a result of the collapse of CanWest. History The ''Vancouver Sun'' published its first edition on 12 February 1912. Th ...

Richmond, British Columbia
Richmond is a coastal city in the Lower Mainland region of British Columbia, Canada. It occupies almost the entirety of Lulu Island (excluding Queensborough), between the two estuarine distributaries of the Fraser River. Encompassing the adjacent Sea Island (where the Vancouver International Airport is located) and several other smaller islands and uninhabited islets to its north and south, it neighbours Vancouver and Burnaby on the Burrard Peninsula to the north, New Westminster and Annacis Island to the east, Delta to the south, and the Strait of Georgia to the west. The Coast Salish peoples were the first people to inhabit the area of Richmond, with the Musqueam Band naming the site near Terra Nova "spələkʷəqs" or "boiling point". As a member municipality of Metro Vancouver, Richmond is composed of eight local neighbourhoods: Sea Island, City Centre, Thompson, West Richmond, Steveston, South Arm, East Richmond and Hamilton. As of 2022, the city has an estim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cyclotrons
A cyclotron is a type of particle accelerator invented by Ernest O. Lawrence in 1929–1930 at the University of California, Berkeley, and patented in 1932. Lawrence, Ernest O. ''Method and apparatus for the acceleration of ions'', filed: January 26, 1932, granted: February 20, 1934 A cyclotron accelerates charged particles outwards from the center of a flat cylindrical vacuum chamber along a spiral path. The particles are held to a spiral trajectory by a static magnetic field and accelerated by a rapidly varying electric field. Lawrence was awarded the 1939 Nobel Prize in Physics for this invention. The cyclotron was the first "cyclical" accelerator. The primary accelerators before the development of the cyclotron were electrostatic accelerators, such as the Cockcroft–Walton accelerator and Van de Graaff generator. In these accelerators, particles would cross an accelerating electric field only once. Thus, the energy gained by the particles was limited by the maximum ...
