Architect of the Capitol

The Architect of the Capitol is the federal agency responsible for the maintenance, operation and preservation of the United States Capitol Complex, the head of that agency. The Architect of the Capitol is in the legislative branch and is accountable to the United States Congress and the Supreme Court. President Trump nominated Brett Blanton as architect of the Capitol on December 9, 2019. On December 19, 2019, the United States Senate confirmed his nomination by voice vote, he was sworn in on January 16, 2020. Blanton replaced acting architect of the Capitol Thomas J. Carroll, who replaced former acting architect of the Capitol Christine A. Merdon. Prior to that, Stephen T. Ayers served as acting architect of the Capitol since February 2007, was unanimously confirmed by the Senate on May 12, 2010, becoming the 11th architect of the Capitol, he retired on November 23, 2018. The architect of the Capitol sits on the Capitol Police Board, which has jurisdiction over the United States Capitol Police, on the United States Capitol Guide Board, which has jurisdiction over the United States Capitol Guide Service.

Until 1989, the architect of the Capitol was appointed by the president of the United States for an indefinite term. Legislation in 1989 provides that the president appoints the architect for a term of ten years, with the advice and consent of the Senate, from a list of three candidates recommended by a congressional commission. On confirmation by the Senate, the architect becomes an official of the legislative branch as an officer and agent of Congress; the architect is eligible for reappointment after completion of the term. The architect of the Capitol is responsible to the United States Congress and the Supreme Court for the maintenance, operation and preservation of 17.4 million square feet of buildings and more than 553 acres of land throughout Capitol Hill. The architect's office is responsible for the upkeep and improvement of the Capitol Grounds, the arrangement of inaugural ceremonies and other ceremonies held in the building or on the grounds. Legislation over the years has placed additional buildings and grounds under the architect of the Capitol.

The Capitol Complex includes the following facilities: the Capitol the Capitol Visitor Center the seven congressional office buildings Cannon Ford Longworth Rayburn Russell Dirksen Hart the Library of Congress buildings the United States Supreme Court Building the United States Botanic Garden the Thurgood Marshall Federal Judiciary Building the Capitol Power Plant the Senate page dormitory the United States Capitol Police headquarters and K9 division facilities other facilities Office of the Supervising Architect for the U.

Archetype (information science)

In the field of informatics, an archetype is a formal re-usable model of a domain concept. Traditionally, the term archetype is used in psychology to mean an idealized model of a person, personality or behaviour; the usage of the term in informatics is derived from this traditional meaning, but applied to domain modelling instead. An archetype is defined by the OpenEHR Foundation as follows: An archetype is a computable expression of a domain content model in the form of structured constraint statements, based on some reference model. OpenEHR archetypes are based on the openEHR reference model. Archetypes are all expressed in the same formalism. In general, they are defined for wide re-use, they can be specialized to include local particularities, they can accommodate any number of natural terminologies. The modern Archetype formalism is specified and maintained by the openEHR Foundation, although developed for the health IT domain, is domain-independent, has been used in geospatial modelling, telecommunications, defence.

The Archetype Formalism consists of a number of specifications including:'ADL 1.4': original release of Archetype Definition Language and Archetype Object Model. The Archetype Technology Overview provides a short technical overview of the archetype formalism useful for new users; the ADL/AOM 1.4 specifications were provided to ISO TC 215 in 2008 by the openEHR Foundation and became the ISO 13606-2 standard, extant until 2019. ISO TC 215 accepted the AOM 2 specification as the basis for a revision of this standard, issued in 2019. In late 2015, the Object Management Group accepted an RfP entitled'Archetype Modeling Language' as a new candidate standard; this specification is a form of ADL re-engineered as a UML profile so as to enable archetype modelling to be supported within UML tools. A number of tools area available for working with archetypes. Most are listed on the openEHR modelling tools page, they include: ADL Designer - modern AOM2-based web editing application Archetype Editor - original desktop clinical modelling tool Template Designer - original desktop clinical templating tool LinkEHR - archetype and data integration tool ADL Workbench - reference compiler and visualiser tool.

Polyelectrolyte

Polyelectrolytes are polymers whose repeating units bear an electrolyte group. Polycations and polyanions are polyelectrolytes; these groups dissociate in aqueous solutions. Polyelectrolyte properties are thus similar to both electrolytes and polymers and are sometimes called polysalts. Like salts, their solutions are electrically conductive. Like polymers, their solutions are viscous. Charged molecular chains present in soft matter systems, play a fundamental role in determining structure and the interactions of various molecular assemblies. Theoretical approaches to describing their statistical properties differ profoundly from those of their electrically neutral counterparts, while technological and industrial fields exploit their unique properties. Many biological molecules are polyelectrolytes. For instance, glycosaminoglycans, DNA are polyelectrolytes. Both natural and synthetic polyelectrolytes are used in a variety of industries. Acids are classified as either strong. Polyelectrolytes can be divided into "weak" and "strong" types.

A "strong" polyelectrolyte is one that dissociates in solution for most reasonable pH values. A "weak" polyelectrolyte, by contrast, has a dissociation constant in the range of ~2 to ~10, meaning that it will be dissociated at intermediate pH. Thus, weak polyelectrolytes are not charged in solution, moreover their fractional charge can be modified by changing the solution pH, counter-ion concentration, or ionic strength; the physical properties of polyelectrolyte solutions are strongly affected by this degree of charging. Since the polyelectrolyte dissociation releases counter-ions, this affects the solution's ionic strength, therefore the Debye length; this in turn affects other properties, such as electrical conductivity. When solutions of two oppositely charged polymers are mixed, a bulk complex is formed; this occurs because the oppositely-charged polymers attract bind together. The conformation of any polymer is affected by a number of factors: notably the polymer architecture and the solvent affinity.

In the case of polyelectrolytes, charge has an effect. Whereas an uncharged linear polymer chain is found in a random conformation in solution, the charges on a linear polyelectrolyte chain will repel each other via double layer forces, which causes the chain to adopt a more expanded, rigid-rod-like conformation. If the solution contains a great deal of added salt, the charges will be screened and the polyelectrolyte chain will collapse to a more conventional conformation. Polymer conformation of course affects many bulk properties. Although the statistical conformation of polyelectrolytes can be captured using variants of conventional polymer theory, it is in general quite computationally intensive to properly model polyelectrolyte chains, owing to the long-range nature of the electrostatic interaction. Techniques such as static light scattering can be used to study polyelectrolyte conformation and conformational changes. Polyelectrolytes that bear both cationic and anionic repeat groups are called polyampholytes.

The competition between the acid-base equilibria of these groups leads to additional complications in their physical behavior. These polymers only dissolve when there is sufficient added salt, which screens the interactions between oppositely charged segments. In case of amphoteric macroporous hydrogels action of concentrated salt solution does not lead to dissolution of polyampholyte material due to covalent cross-linking of macromolecules. Synthetic 3-D macroporous hydrogels shows the excellent ability to adsorb heavy-metal ions in a wide range of pH from diluted aqueous solutions, which can be used as an adsorbent for purification of salty water All proteins are polyampholytes, as some amino acids tend to be acidic, while others are basic. Polyelectrolytes have many applications related to modifying flow and stability properties of aqueous solutions and gels. For instance, they can be used to initiate flocculation, they can be used to impart a surface charge to neutral particles, enabling them to be dispersed in aqueous solution.

They are thus used as thickeners, conditioners, clarifying agents, drag reducers. They are used for oil recovery. Many soaps and cosmetics incorporate polyelectrolytes. Furthermore, they are added to concrete mixtures; some of the polyelectrolytes that appear on food labels are pectin, carrageenan and carboxymethyl cellulose. All but the last are of natural origin, they are used in a variety of materials, including cement. Because some of them are water-soluble, they are investigated for biochemical and medical applications. There is much research in using biocompatible polyelectrolytes for implant coatings, for controlled drug release, other applications, thus the biocompatible and biodegradable macroporous material composed of polyelectrolyte complex was described, where the material exhibited excellent proliferation of mammalian cells and muscle like soft actuators. Polyelectrolytes have been used in the formation of new types of materials known as polyelectrolyte multilayers; these thin films are constructed using a la

Leda (river)

Leda is a river in north-western Germany in the state of Lower Saxony. The Leda is a right tributary of the Ems and originates at the confluence of the Sagter Ems and the Dreyschloot near Barßel; the Leda flows into the Ems near the town of Leer. On the southern bank of the Leda, in the Overledingen Land, opposite Leer, lies the small settlement of Kloster Muhde; the total length of the river is 24.2 kilometres. The lower 1.85 kilometres until the port of Leer are navigable for large ships, a further 7 km until the mouth of the Jümme for Class II ships and a further 16 km until the Elisabethfehnkanal are navigable but not classified. In East Frisia the Sagter Ems, a headstream of the Leda, is known as the Leda. List of rivers of Lower Saxony

Gray Television

Gray Television, Inc. is an American publicly traded television broadcasting company based in Atlanta, Georgia. Founded in 1946 by James Harrison Gray as Gray Communications Systems, the company owns or operates 145 stations across the United States, based in markets as large as Cleveland and as small as North Platte, Nebraska. James H. Gray started his communication business with the purchase of The Albany Herald in 1946 after he returned from World War II. Gray launched WALB-TV in 1954. In 1960, Gray purchased WJHG-TV in Panama City, FL, followed it in the decade with KTVE serving Monroe, LA and southern Arkansas. In 1986 Gray died, leaving his 50.5% share of the stock in a trust for his children with stipulation that they run the business together, sell their stock with each other or sell out together. This caused difficulties. In 1991, to break the stalemate, the board of directors had the company purchase 25% of their shares; the company was taken public on NASDAQ's small-cap market in the 2nd quarter 1992.

The price per share dropped to $8. The company put itself-or any part up-for sale by the end of 1992. While the board of directors received about 40 offers, Bull Run Corporation purchased the remaining shares of the Gray siblings, who as part of the deal resigned from the board. New management was put in place at all three TV stations. Bull Run Corporation owned by J. Mack Robinson, decided to make Gray a Southeast regional media company, expanding its focus beyond the state of Georgia. Gray purchased two TV stations from the failed and government seized Kentucky Central Life Insurance Co. in September 1994 after a court challenge to the sale by Kentucky Central builder Garvie Kincaid. In 1994 and 1995, Gray purchased two newspapers, the Rockdale Citizen and Gwinnett Post-Tribune and seven advertising weeklies. In 1995, the company moved its stock listing to the New York Stock Exchange. By this time, directly or through Bull Run, owned 44% of the company's stock. Gray had started to focus on its TV station segment over the newspaper holding while TV produced more income and the newspapers' income were declining.

Just months after doubling the Daily Post's staff, one third were laid off and a quarter of The Albany Herald's staff followed in January 1996. Newspaper leaders resigned during this period–from the corporate president in late 1995 to the Citizens' editor and publisher. In 1996, Gray added additional TV stations while entering additional communication industry segments; the company was considered in 1996 by Fortune magazine as the 81st fastest growing company, having a 48% percent growth rate. WRDW-TV was purchased in January 1996. In September 1996 a basket purchase from Inc.. Gray got two TV stations and Production Business Services, renamed Lynqx Communications and PortaPhone paging business. In August and September 1996, Gray raised additional operating funds by various means. On August 20, KTVE accounts receivable; the company issued and sold Class B common stock, senior subordinated notes and preferred stock in September. A new bank credit facility was arranged; this brought the company total to $534.5 million in available funds with $409.5 million directly available.

In September 1996, Ralph Gabbard, the newly named president and CEO, died from a heart attack at age 50. Robinson, Bull Run's chair, took over as interim CEO and president with Bull Run CEO Robert Prather as interim executive vice-president, acquisitions. With its additional funds, Gray continued purchasing in 1997 with two announcements in January and February; the company bought Gulflink Communications, Inc. a transportable satellite uplink business based in Baton Rouge, Louisiana, in April 1997 to go along with Lynqx. With Raycom Media acquiring a station from AFLAC Broadcast Group, Inc. forcing them to sell WITN-TV to Gray, finalized on August 1, 1997. The Gwinnett Daily Post increased circulation in 1997 through a deal with Genesis Cable Communications to provide the paper to its metro Atlanta subscribers at Genesis's expense. In 1998, Gray started to expand beyond its Southeast region; as the company agreed to purchase the Busse Broadcasting Corporation, which owned KOLN, KGIN-TV and WEAU.

Gray's ownership of a newspaper and TV station in Albany, Georgia while grandfathered was examined under the Media cross-ownership rule of the FCC due to this potential purchase. WALB was thus sold to Liberty Corp.'s Cosmos Broadcasting in August 1998. In 2002, Robinson became Chairman and CEO, his son-in-law Hilton Howell vice chairman, Prather president/COO and Jim Ryan senior vice president, they had Gray purchase 14 Benedek Broadcasting stations. In 2006, the company spun off its five daily newspapers and wireless messaging business into the newly formed Triple Crown Media is renamed Southern Community Newspapers. A new strategy of purchasing stations in college towns or capitals was put into place; the company had overpaid for a pair of stations and was over leveraged like many other station groups entering the Great Recession. Advertising revenues dropped; the twin problems caused its shares to trade at its lowest at 16 cents in 2008, thus the NYSE indicated they might delist the company.

Loan covenants could have forced the company into default. Robinson stepped down with Howell replacing him in 2008. On July 30, 2009, Gray was awarded a contract to manage seven Young Broadcasting-owned stations. Through December 31, 2012, Gray would earn $2.2 million and an opportunity to earn additional specified incentive fees
