Berwyn, Pennsylvania
Berwyn is a census-designated place (CDP) in Chester County, Pennsylvania, United States. Berwyn is located in Tredyffrin and Easttown townships. The area is part of the Philadelphia Main Line suburbs. History In 1877, the town received its current name, Berwyn, which a Welsh settler proposed after the Berwyn range overlooking the River Dee in Denbighshire, Wales. Prior to 1877, the village was named Cocheltown, Reeseville, Glassley, and Gaysville. The Berwyn School Fight was a 1930s campaign against school segregation. In 1932, local school districts tried to segregate elementary schools by race. Black families sued to stop the segregationists and boycotted the segregated schools until the school districts finally conceded defeat in 1934. Occurring 20 years before '' Brown v. Board of Education'' (1954) declared school segregation to be unconstitutional nationwide, the Berwyn School Fight was a landmark early victory for the civil rights movement. Geography Berwyn ...

VTI Instruments
VTI Instruments Corporation sells precision instrumentation for electronic signal distribution, data acquisition and monitoring. The company's products are used to automate the functional testing of complex electronic systems as well as to monitor and record data that characterizes the physical integrity of aircraft, engines, and other large structures. Formerly known as VXI Technology, it changed its name in 2009. VTI serves the following markets: aerospace, defense, and energy and power generation. VTI's headquarters is located in Irvine, California. History Founded in 1990, VTI initially developed prototyping tools and offered custom design services. By 1997, VTI had introduced two new VXI-based instrumentation and signal switching platforms for functional test/ATE – the VMIP and SMIP series. In 2003, VTI purchased Agilent's mechanical test business unit, which expanded the company's product offering to address precision data acquisition and signal conditioning applications. ...

X-ray Fluorescence
X-ray fluorescence (XRF) is the emission of characteristic "secondary" (or fluorescent) X-rays from a material that has been excited by being bombarded with high-energy X-rays or gamma rays. The phenomenon is widely used for elemental analysis and analytical chemistry, chemical analysis, particularly in the investigation of metals, glass, ceramics and building materials, and for research in geochemistry, forensic science, archaeology and art objects such as paintings. Underlying physics When materials are exposed to short-wavelength X-rays or to gamma rays, ionization of their component atoms may take place. Ionization consists of the ejection of one or more electrons from the atom, and may occur if the atom is exposed to radiation with an energy greater than its ionization energy. X-rays and gamma rays can be energetic enough to expel tightly held electrons from the inner atomic orbital, orbitals of the atom. The removal of an electron in this way makes the electronic structu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Viscosity
Viscosity is a measure of a fluid's rate-dependent drag (physics), resistance to a change in shape or to movement of its neighboring portions relative to one another. For liquids, it corresponds to the informal concept of ''thickness''; for example, syrup has a higher viscosity than water. Viscosity is defined scientifically as a force multiplied by a time divided by an area. Thus its SI units are newton-seconds per metre squared, or pascal-seconds. Viscosity quantifies the internal friction, frictional force between adjacent layers of fluid that are in relative motion. For instance, when a viscous fluid is forced through a tube, it flows more quickly near the tube's center line than near its walls. Experiments show that some stress (physics), stress (such as a pressure difference between the two ends of the tube) is needed to sustain the flow. This is because a force is required to overcome the friction between the layers of the fluid which are in relative motion. For a tube ...

Public Company
A public company is a company whose ownership is organized via shares of share capital, stock which are intended to be freely traded on a stock exchange or in over-the-counter (finance), over-the-counter markets. A public (publicly traded) company can be listed on a stock exchange (listing (finance), listed company), which facilitates the trade of shares, or not (unlisted public company). In some jurisdictions, public companies over a certain size must be listed on an exchange. In most cases, public companies are ''private'' enterprises in the ''private'' sector, and "public" emphasizes their reporting and trading on the public markets. Public companies are formed within the legal systems of particular states and so have associations and formal designations, which are distinct and separate in the polity in which they reside. In the United States, for example, a public company is usually a type of corporation, though a corporation need not be a public company. In the United Kin ...

Metrology
Metrology is the scientific study of measurement. It establishes a common understanding of Unit of measurement, units, crucial in linking human activities. Modern metrology has its roots in the French Revolution's political motivation to standardise units in France when a length standard taken from a natural source was proposed. This led to the creation of the decimal-based metric system in 1795, establishing a set of standards for other types of measurements. Several other countries adopted the metric system between 1795 and 1875; to ensure conformity between the countries, the ''International Bureau of Weights and Measures, Bureau International des Poids et Mesures'' (BIPM) was established by the Metre Convention. This has evolved into the International System of Units (SI) as a result of a resolution at the 11th General Conference on Weights and Measures (CGPM) in 1960. Metrology is divided into three basic overlapping activities: * The definition of units of measurement * ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
