Victor Mayer
Victor Mayer (1857 in Pforzheim – 1946) founded the jewellery manufacture Victor Mayer in Pforzheim in 1890. In the time of Jugendstil / Art Nouveau, the company created pieces based on the designs of well-known artists such as the jewellery designer Professor Georg Kleemann or Anton Krautheimer of the Munich Secession. In the art deco period and in the 1950s the manufacture focused mainly on fine gold and silver ware. From the 1970s onwards again more jewellery was manufactured. Until 1988 the company produced Fabergé jewelry for Fabergé & Cie in Paris with the label 'Fabergé Paris'. From 1925 until 2009, the company continued to produce Fabergé jewelry under license from Unilever New York until the brand license was sold. The manufacture Victor Mayer is well known for its high-end jewellery and the preservation of historical artisan techniques such as authentic fire enamel or guilloché. Life Victor Mayer was born in 1857 into a family of thriving entrepreneurs. His father ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Norton's Theorem
In direct-current circuit theory, Norton's theorem, also called the Mayer–Norton theorem, is a simplification that can be applied to networks made of linear time-invariant resistances, voltage sources, and current sources. At a pair of terminals of the network, it can be replaced by a current source and a single resistor in parallel. For alternating current (AC) systems the theorem can be applied to reactive impedances as well as resistances. The Norton equivalent circuit is used to represent any network of linear sources and impedances at a given frequency. Norton's theorem and its dual, Thévenin's theorem, are widely used for circuit analysis simplification and to study circuit's initial-condition and steady-state response. Norton's theorem was independently derived in 1926 by Siemens & Halske researcher Hans Ferdinand Mayer (1895–1980) and Bell Labs engineer Edward Lawry Norton (1898–1983). To find the equivalent, the Norton current ''I''no is calculated as th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mayer, Arizona
Mayer is a census-designated place (CDP) in Yavapai County, Arizona, United States. The population was 1,408 at the 2000 census. Mayer includes three sites listed on the National Register of Historic Places: Mayer Apartments, Mayer Business Block, and Mayer Red Brick Schoolhouse. History The place was originally called Wi:kidoʼyoʼ in Yavapai. From May to June 1942, 245 Japanese Americans were confined at the Mayer Assembly Center, one of 17 temporary detention camps built to hold Japanese Americans removed from the West Coast after the U.S. entered World War II. The 69 families were mostly from Maricopa County's Salt River Valley area, and lived in military-style barracks on the converted Civilian Conservation Corps camp for just under a month before being transferred to the more permanent and isolated internment camp at Poston, Arizona. 2017 wildfire The Goodwin Fire sparked on June 24, 2017, in the Bradshaw Mountains near the town of Mayer, which days later led to t ...

Mayer Brown
Mayer Brown is a global white-shoe law firm, headquartered in Chicago, Illinois, United States. It has offices in 27 cities across the Americas, Asia, Europe, and the Middle East, with its largest offices being in Chicago, Washington, D.C., New York City, Hong Kong, and London. Mayer Brown has more than 1,800 lawyers and by revenue is the 19th largest law firm in the world. History The three firms that now form the core of Mayer Brown were all founded in the 19th century. The US portion of the firm was founded in 1881 in Chicago, by Adolf Kraus and Levy Mayer, and was shortly thereafter known as ''Kraus, Mayer & Brackett''. After several changes in name to reflect its changing membership, the firm eventually became known in the US as ''Mayer, Brown & Platt''. The English portion of the firm, ''Rowe & Maw'', was established in 1895 in London and operated under that name until joining with ''Mayer, Brown & Platt'' in 2002 to form ''Mayer, Brown, Rowe & Maw''. In 2007, the amalgama ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cluster Expansion
In statistical mechanics, the cluster expansion (also called the high temperature expansion or hopping expansion) is a power series expansion of the partition function of a statistical field theory around a model that is a union of non-interacting 0-dimensional field theories. Cluster expansions originated in the work of . Unlike the usual perturbation expansion which usually leads to a divergent asymptotic series, the cluster expansion may converge within a non-trivial region, in particular when the interaction is small and short-ranged. Classical case General theory In statistical mechanics, the properties of a system of noninteracting particles are described using the partition function. For N noninteracting particles, the system is described by the Hamiltonian : \big. H_0=\sum_i^N \frac, and the partition function can be calculated (for the classical case) as :\big. Z_0 =\frac\int \prod_i d\vec_i\;d\vec_i \exp\left\ =\frac\left( \frac \right)^. From the partition functio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mayer F-function
The Mayer f-function is an auxiliary function that often appears in the series expansion of thermodynamic quantities related to classical many-particle systems.Donald Allan McQuarrie, ''Statistical Mechanics'' (HarperCollins, 1976), page 228 It is named after chemist and physicist Joseph Edward Mayer. Definition Consider a system of classical particles interacting through a pair-wise potential :V(\mathbf,\mathbf) where the bold labels \mathbf and \mathbf denote the continuous degrees of freedom associated with the particles, e.g., :\mathbf=\mathbf_i for spherically symmetric particles and :\mathbf=(\mathbf_i,\Omega_i) for rigid non-spherical particles where \mathbf denotes position and \Omega the orientation parametrized e.g. by Euler angles. The Mayer f-function is then defined as :f(\mathbf,\mathbf)=e^-1 where \beta=(k_T)^ the inverse absolute temperature in units of (Temperature times the Boltzmann constant k_)−1 .

Mayer's Relation
In the 19th century, German chemist and physicist Julius von Mayer derived a relation between specific heat at constant pressure and the specific heat at constant volume for an ideal gas. Mayer's relation states that :C_ - C_ = R, where is the molar specific heat at constant pressure, is the molar specific heat at constant volume and is the gas constant. For more general homogeneous substances, not just ideal gases, the difference takes the form, :C_ - C_= V_ T\frac\, (see relations between heat capacities), where V_ is the molar volume, T is the temperature, \alpha_ is the thermal expansion coefficient and \beta is the isothermal compressibility. From this latter relation, several inferences can be made: * Since the isothermal compressibility \beta_ is positive for nearly all phases, and the square of thermal expansion coefficient is always either a positive quantity or zero, the specific heat at constant pressure is nearly always greater than or equal to specific heat at c ...
