Behavioral Enrichment
Behavioral enrichment is an animal husbandry principle that seeks to enhance the quality of captive animal care by identifying and providing the environmental stimuli necessary for optimal psychological and physiological well-being. Enrichment can either be active or passive, depending on whether it requires direct contact between the animal and the enrichment. A variety of enrichment techniques are used to create desired outcomes similar to an animal's individual and species' history. Each of the techniques used is intended to stimulate the animal's senses similarly to how they would be activated in the wild. Provided enrichment may be seen in the form of auditory, olfactory, habitat factors, food, research projects, training, and objects. Purpose Environmental enrichment can improve the overall welfare of animals in captivity and create a habitat similar to what they would experience in their wild environment. It aims to maintain an animal's physical and psychological health b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Enrichment
Enriched uranium is a type of uranium in which the percent composition of uranium-235 (written 235U) has been increased through the process of isotope separation. Naturally occurring uranium is composed of three major isotopes: uranium-238 (238U with 99.2739–99.2752% natural abundance), uranium-235 (235U, 0.7198–0.7202%), and uranium-234 (234U, 0.0050–0.0059%). 235U is the only primordial nuclide, nuclide existing in nature (in any appreciable amount) that is fissile with thermal neutrons. Enriched uranium is a critical component for both civil Nuclear power, nuclear power generation and military nuclear weapons. The International Atomic Energy Agency attempts to monitor and control enriched uranium supplies and processes in its efforts to ensure nuclear power generation safety and curb nuclear proliferation, nuclear weapons proliferation. There are about 2,000 tonnes of highly enriched uranium in the world, produced mostly for nuclear power, nuclear weapons, Nuclear ...

GO Term Enrichment
Gene Ontology (GO) term enrichment is a technique for interpreting sets of genes making use of the Gene Ontology system of classification, in which genes are assigned to a set of predefined bins depending on their functional characteristics. For example, the gene FasR is categorized as being a receptor, involved in apoptosis and located on the plasma membrane. Researchers performing high-throughput experiments that yield sets of genes (for example, genes that are differentially expressed under different conditions) often want to retrieve a functional profile of that gene set, in order to better understand the underlying biological processes. This can be done by comparing the input gene set with each of the bins (terms) in the GO – a statistical test can be performed for each bin to see if it is enriched for the input genes. The output of the analysis is typically a ranked list of GO terms, each associated with a p-value. Background The Gene Ontology The Gene Ontolog ...

Enriched Category
In category theory, a branch of mathematics, an enriched category generalizes the idea of a category by replacing hom-sets with objects from a general monoidal category. It is motivated by the observation that, in many practical applications, the hom-set often has additional structure that should be respected, e.g., that of being a vector space of morphisms, or a topological space of morphisms. In an enriched category, the set of morphisms (the hom-set) associated with every pair of objects is replaced by an object in some fixed monoidal category of "hom-objects". In order to emulate the (associative) composition of morphisms in an ordinary category, the hom-category must have a means of composing hom-objects in an associative manner: that is, there must be a binary operation on objects giving us at least the structure of a monoidal category, though in some contexts the operation may also need to be commutative and perhaps also to have a right adjoint (i.e., making the category sym ...

Living Enrichment Center
Living Enrichment Center (LEC) was a New Thought organization and retreat center in the U.S. state of Oregon. It was founded in the farmhouse of senior minister Mary Manin Morrissey of Scholls, Oregon, in the mid-1970s; the church moved to a 94,500 square foot (8,800 m²) building on a forested area of 95 acres (384,000 m²) in Wilsonville in 1992. Over the course of its existence, the congregation grew from less than a dozen to an estimated 4,000, making it the biggest New Thought church in the state. Living Enrichment Center maintained an in-house bookstore, retreat center, café, kindergarten and elementary school, and an outreach television ministry. Living Enrichment Center closed in 2004 as a result of a $10.7 million financial scandal. Edward Morrissey pleaded guilty to money laundering and using church money for the personal expenses of himself and his wife. He was sentenced to two years in federal prison. He was released in early 2007. Living Enrichment Center dissolve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Enrichment Center Percussion Ensemble
The Enrichment Center Percussion Ensemble is a musical group based at the Enrichment Center, Winston-Salem, North Carolina formed from adults with developmental disabilities and professional musicians. It was founded in 1997 by director Aaron Bachelder from members of the existing student body of the Enrichment Center, an arts-based alternative day program for adults with disabilities. In spite of its members' lack of prior musical experience, the group began performing within months, and was soon attracting the attention of many in the arts and human services communities. Before long, they had performed for thousands of people, alone and in collaboration with such groups as The African American Dance Ensemble, Chimaera Physical Theatre, and more recently, The Open Dream Ensemble. The group's music is highly varied, ranging from neo-serialism to post- minimalist rock, as well as arrangements of American folk song and works drawing on Asian, Latin, and jazz traditions. Their first ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unjust Enrichment
In laws of equity, unjust enrichment occurs when one person is enriched at the expense of another in circumstances that the law sees as unjust. Where an individual is unjustly enriched, the law imposes an obligation upon the recipient to make restitution, subject to defences such as change of position. Liability for an unjust (or unjustified) enrichment arises irrespective of wrongdoing on the part of the recipient. The concept of unjust enrichment can be traced to Roman law and the maxim that "no one should be benefited at another's expense": ''nemo locupletari potest aliena iactura'' or ''nemo locupletari debet cum aliena iactura''. The law of unjust enrichment is closely related to, but not co-extensive with, the law of restitution. The law of restitution is the law of gain-based recovery. It is wider than the law of unjust enrichment. Restitution for unjust enrichment is a subset of the law of restitution in the same way that compensation for breach of contract is a subset of ...

United States Enrichment Corporation
Centrus Energy Corp. (formerly USEC Inc.) is an American company that supplies nuclear fuel for use in nuclear power plants and works to develop and deploy advanced centrifuge technology to produce enriched uranium for commercial and government uses, including for national security. In 2019, Centrus began work under a contract with the U.S. Department of Energy to build a cascade of 16 centrifuges in Piketon, Ohio to demonstrate production of High-Assay, Low-Enriched Uranium, or HALEU. HALEU is required for many next generation reactor designs, including nine of the ten reactor designs selected under the Energy Department’s Advanced Reactor Demonstration Program. In June 2021, the U.S. Nuclear Regulatory Commission approved a license amendment request for Centrus to enrich uranium up to a Uranium-235 concentration of 20 percent, making it the first U.S. facility licensed for HALEU production. This is higher than the 5 percent level found in Low-Enriched Uranium that is used in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Job Enrichment
Job enrichment is a method of motivating employees where a job is designed to have interesting and challenging tasks which can require more skill and can increase pay. Origin Frederick Herzberg, an American psychologist, originally developed the concept of 'job enrichment' in 1968, in an article that he published on pioneering studies at AT&T.Frederick Herzberg, HBR Jan 2003, One More Time: How Do You Motivate Employees? Retrieved from https://hbr.org/2003/01/one-more-time-how-do-you-motivate-employees/ar/1 The concept stemmed from Herzberg's motivator-hygiene theory, which is based on the premise that job attitude is a construct of two independent factors, namely job satisfaction and job dissatisfaction. Job satisfaction encompasses intrinsic factors which arise from the work itself, including achievement and advancement, whilst job dissatisfaction stems from factors external to the actual work, including company policy and the quality of supervision. He came up with this term w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Data Management
Data management comprises all disciplines related to handling data as a valuable resource. Concept The concept of data management arose in the 1980s as technology moved from sequential processing (first punched cards, then magnetic tape) to random access storage. Since it was now possible to store a discrete fact and quickly access it using random access disk technology, those suggesting that data management was more important than business process management used arguments such as "a customer's home address is stored in 75 (or some other large number) places in our computer systems." However, during this period, random access processing was not competitively fast, so those suggesting "process management" was more important than "data management" used batch processing time as their primary argument. As application software evolved into real-time, interactive usage, it became obvious that both management processes were important. If the data was not well defined, the data wo ...

Nitrox
Nitrox refers to any gas mixture composed (excepting trace gases) of nitrogen and oxygen. This includes atmospheric air, which is approximately 78% nitrogen, 21% oxygen, and 1% other gases, primarily argon. In the usual application, underwater diving, nitrox is normally distinguished from air and handled differently. The most common use of nitrox mixtures containing oxygen in higher proportions than atmospheric air is in scuba diving, where the reduced partial pressure of nitrogen is advantageous in reducing nitrogen uptake in the body's tissues, thereby extending the practicable underwater dive time by reducing the decompression requirement, or reducing the risk of decompression sickness (also known as ''the bends''). Nitrox is used to a lesser extent in surface-supplied diving, as these advantages are reduced by the more complex logistical requirements for nitrox compared to the use of simple low-pressure compressors for breathing gas supply. Nitrox can also be used in hyper ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chaptalization
Chaptalization is the process of adding sugar to unfermented grape must in order to increase the alcohol content after fermentation. The technique is named after its developer, the French chemist Jean-Antoine-Claude Chaptal. This process is not intended to make the wine sweeter, but rather to provide more sugar for the yeast to ferment into alcohol. Chaptalization has generated controversy and discontent in the French wine industry due to advantages that the process is perceived to give producers in poor-climate areas. In response to violent demonstrations by protesters in 1907, the French government began regulating the amount of sugar that can be added to wine. Chaptalization is sometimes referred to as enrichment, for example in the European Union wine regulations specifying the legality of the practice within EU. The legality of chaptalization varies by country, region, and even wine type. In general, it is legal in regions that produce grapes with low sugar content, such as ...
