Philip Vassar Hunter. Philip Vassar Hunter CBE (c. 1883 – ) was a British engineer and businessman. Born in 1883 in Emneth Hungate, Norfolk, he attended Wisbech Grammar School and was later educated at Faraday House, an engineering college in Charing Cross, London.

During the First World War, he served as the Engineering Director in the experiments and research section of the anti-submarine division of the Naval Staff and was appointed a CBE in January 1920. In the Second World War, he invented the buoyant cable, which significantly contributed to the defeat of the magnetic mine. In 1933,  he held the position of president of the Institution of Electrical Engineers, of which he became on honorary fellow in 1951, recognized for his "outstanding service to the electrical industry and to the institution".

He served as president of the British Ice Hockey Association from 1934 to 1958 and was responsible for hiring John F "Bunny" Ahearne as the Manager of the Great Britain national ice hockey team in 1934. Under his leadership, the team achieved the remarkable feat of winning the gold medal at the 1936 Winter Olympics. He died at the age of 73 at his home in Addington, Surrey.

UNS C69100. UNS C69100, also known as Tungum alloy, CW700R and CZ127, is a bronze copper alloy. It has a naturally occurring oxide layer, which on exposure to reagents develops into a very thin protective coating. Tungum resists both pitting and crevice corrosion in marine environments/atmospheres. This offers excellent service-life, even at intermittent duty in the corrosive "splash" zone.

Tungum is non-magnetic and has non-sparking properties. This allows Tungum to be used in high pressure gas pipework systems (oxygen and inert gases). Unusually for a copper alloy, it can be precipitation hardened using heat treatment techniques. This enables its physical properties to be modified as required, to suit various applications. It can be used for low temperature (cryogenic) applications.

In the decade after World War I, Sidney Tungay, a metallurgist, was experimenting with a new copper-based alloy which he hoped would look like gold when polished and which would be durable in everyday use. In an article in the 1934 British Trade Review, Tungum alloy was introduced thus:

"Tungum is an alloy discovered by a well known metallurgist from whose name the alloy is derived. Experimenting with a view to finding a combination of metals suitable for a special purpose he had in view, he produced a compound which is known as TUNGUM. Recognising that its close likeness to 22 carat gold would make it a marketable commodity the inventor carried out a series of tests which satisfied him that he had discovered a wonderful alloy."

The material is now mainly used in commercial diving and offshore applications, for the material's resistance to salt water corrosion.

Its composition is: 81-84% Cu, 0.70-1.20 Al, 0.8-1.40 Ni, 0.80-1.30 Si, with the remainder Zn

Core data integration. Core data integration is the use of data integration technology for a significant, centrally planned and managed IT initiative within a company. Examples of core data integration initiatives could include:

 ETL (Extract, transform, load) implementations
 EAI (Enterprise Application Integration) implementations
 SOA (Service-Oriented Architecture) implementations
 ESB (Enterprise Service Bus) implementations

Core data integrations are often designed to be enterprise-wide integration solutions. They may be designed to provide a data abstraction layer, which in turn will be used by individual core data integration implementations, such as ETL servers or applications integrated through EAI.

Because it is difficult to promptly roll out a centrally managed data integration solution that anticipates and meets all data integration requirements across an organization, IT engineers and even business users create edge data integration, using technology that may be incompatible with that used at the core. In contrast to a core data integration, an edge data integration is not centrally planned and is generally completed with a smaller budget and a tighter deadline.

Data management
Data integration
Edge data integration. An edge data integration is an implementation of data integration technology undertaken in an ad hoc or tactical fashion. This is also sometimes referred to as point-to-point integration because it connects two types of data directly to serve a narrow purpose. Many edge integrations, and actually the vast majority of all data integration, involve hand-coded scripts. Some may take the form of Business Mashups (web application hybrids), Rich Internet applications, or other browser-based models that take advantage of Web 2.0 technologies to combine data in a Web browser.

Examples of edge data integration projects might be:

 extracting a list of customers from a host Sales Force Automation application and writing the results to an Excel spreadsheet
 creating a script-driven framework for managing RSS feeds
 combining data from a weather Web site, a shipping company's Web site, and a company's internal logistics database to track shipments and estimated arrival times of packages

It has been claimed that edge data integration do not typically require large budgets and centrally managed technologies, which is in contrast to a core data integration.

Thomas William Moseley. Thomas William Henry Harrison Moseley (November 28, 1813 – March 10, 1880) was a builder and designer of wrought-iron arch bridges. He is best known for his "Wrought-Iron Lattice Girder Bridge" patent of August 30, 1870. The only known surviving example of this type of bridge structure is the Hares Hill Road Bridge located in Chester County, Pennsylvania.

Biography
Thomas W.H. Moseley was born near Mt. Sterling, Kentucky on November 28, 1813. He died in Scranton, Pennsylvania on March 10, 1880. He was referred to at times as "Gen. Moseley" because of his time as state adjutant-general in Ohio in the 1840s to early 1850s. He got started in business in Cincinnati, Ohio in the 1850s, which is when Zenas King was on board. By 1861, T.W.H Moseley had made his move to Boston, Massachusetts, and Zenas King started his own company in Cleveland, Ohio. By the early 1870s Thomas Moseley was living in Pennsylvania; Philadelphia first, then in Scranton.

Saint Paul City Hall and Ramsey County Courthouse. The Saint Paul City Hall and Ramsey County Courthouse, located at 15 Kellogg Boulevard West in Saint Paul, Ramsey County, in the U.S. state of Minnesota, is a twenty-story Art Deco skyscraper completed in 1932. Built during the Great Depression—a period of high unemployment and falling prices—the building's four-million-dollar budget was underspent, resulting in higher quality materials and craftsmanship than initially expected.

The exterior consists of smooth Indiana limestone in the Art Deco style known as "American Perpendicular." The building was designed by Thomas Ellerbe & Company of Saint Paul and Holabird & Root of Chicago, drawing inspiration from Finnish architect Eliel Saarinen. The vertical rows of windows are connected by plain, flat, black spandrels. Above the Fourth Street entrance and flanking the Kellogg Boulevard entrance are relief sculptures carved by Lee Lawrie.

The interior design, in the "Zigzag Moderne" style, was inspired by the Exposition Internationale des Arts Décoratifs et Industriels Modernes, which emphasized soft ornamentation and sensuous curves. In Memorial Hall, the white marble floor contrasts with three-story black marble piers that lead to a gold-leaf ceiling. At the end of the hall stands the 60-ton,  white onyx sculpture Indian God of Peace by Carl Milles, later renamed Vision of Peace.

Other notable features include woodwork crafted from twenty-three different species of wood and five types of imported marble. Murals were painted by John W. Norton, and the six bronze elevator doors were created by Albert Stewart.

Aaron D. Wyner. Aaron D. Wyner (March 17, 1939 – September 29, 1997) was an American information theorist noted for his contributions in coding theory, particularly the Gaussian channel. He lived in South Orange, New Jersey.

Wyner was born in the Bronx, New York. In 1955, he graduated from the Bronx High School of Science, and in 1960 completed a five-year joint engineering program with Queens College of the City University of New York and Columbia University. In 1963 he received his Ph.D. in electrical engineering from Columbia University for a thesis that worked out the algebra for convolutional codes.

After a summer job at the IBM Thomas J. Watson Research Center, Wyner joined Bell Laboratories at Murray Hill, New Jersey, as a member of the technical staff. In 1974 he became head of its Communications Analysis Research Department and led it until 1993, when he became a researcher in the information theory department.

His research included coding theory, optical communications, cryptography, and stochastic process. In a 1975 paper, he introduced the "wire-tap channel", showing how one could obtain "perfect secrecy" when a receiver enjoys a better channel than does the wire-tapping opponent.

Wyner was a member of the National Academy of Engineering, an IEEE Fellow, and received all the IEEE Information Theory Society awards, i.e., the Claude E. Shannon Award, Prize Paper Award, and designation as Shannon Lecturer.

N-Nitrosodiethylamine. N-Nitrosodiethylamine (NDEA) is an organic compound with the formula Et2NNO (Et = C2H5).  A member of the nitrosamines, it is a light-sensitive, volatile, clear yellow oil that is soluble in water, lipids, and other organic solvents. It has an amine or aromatic odor. It is used as gasoline and lubricant additive, antioxidant, and stabilizer for industry materials. When heated to decomposition, N-nitrosodiethylamine emits toxic fumes of nitrogen oxides. N-Nitrosodiethylamine affects DNA integrity, probably by alkylation, and is used in experimental research to induce liver tumorigenesis. It is carcinogenic and mutagenic. NDEA has also been found to perturb amino acid biosynthesis including arginine, as well as DNA damage repair and mitochondrial genome maintenance in yeast.

It is found in tobacco smoke.

It is classified as a Group 2A carcinogen (probable human carcinogen) by the World Health Organization.

NDEA involvement in recalls 
In the year 2019, NDEA was found as an impurity in valsartan and other angiotensin II receptor blockers (ARBs) used to treat high blood pressure and heart failure. The U.S. Food and Drug Administration has confirmed levels of NDEA and/or NDMA exceeding the interim acceptable intake limits, and the affected medicines were recalled.

Merocyanine. Merocyanines are a class of polymethine dyes which are clearly defined by set structural properties. Merocyanines belong to the group of dyes referred to as functional dyes, where their applications are not only determined by their colour, but also their valuable chemical properties. 

These dyes are usually intensely colored and have large extinction coefficients.

Merocyanine 540 was the first fluorescent dye used for measuring membrane potential, while Brooker's merocyanine and related compounds are notable for their solvatochromatic properties.

Definition 

Conventionally, merocyanine class includes streptocyanines and their analogues where both the nitrogen atom and carbonyl group (or any other electron-withdrawing group containing a multiple carbon-heteroatomic bond, e.g. amino group) can form part of a heterocyclic system. Like ionic cyanines, merocyanines contain two terminal heteroatoms and a polymethine chain in their chromophores.

Prospect Electricity. Prospect Electricity was the state-owned corporation owned by the Government of New South Wales, Australia, that was responsible for retailing electricity to consumers in the Greater Western Sydney region between 1991 and 1996.

It was founded in 1957 as the Prospect County Council, as a spin-off from the Sydney County Council, which was responsible for supplying electricity to much of the eastern half of Sydney. As with the Sydney County Council, it was controlled by local councils in the area, until 1989 when the state government began to take control of electricity suppliers. Local government control was fully ended in 1991, when Prospect Electricity, a government business enterprise, was formed. On 1 March 1996, Prospect Electricity was merged with Illawarra Electricity to form Integral Energy, in preparation for the National Electricity Market & electricity deregulation.

Unibuffel. The Unibuffel is a mine-protected wheeled MRAP Infantry mobility vehicle used by the Sri Lankan military, which is an improved version of the Unicorn, made by the Sri Lanka Electrical and Mechanical Engineers.

More than 53 Unibuffels had been manufactured as of 2006.

Production history
Although similar to the South African Buffel, it is built entirely by the Sri Lanka Electrical and Mechanical Engineers (SLEME). Initial research and development started in 1997 in an effort to field modernized MRAPs in Sri Lankan military service. First production started in 2000.

In 2019, SLEME began to upgrade Unibuffels with blast shock absorption seats and better protection. In 2020 full Air Conditioning was added to those being sent for UN peacekeeping operations in Mali.

Combat Usage

The Unibuffel proved quite successful in the Sri Lankan civil war, it could transport troops through rough terrain with ease, and had good protection, it participated in all Sri Lankan Army operations 2005 onwards.

When Sri Lankan troops joined United Nations Stabilisation Mission in Haiti, 16 Unibuffels was deployed to serve as their APC. 

In June, 2020 nine Unibuffels were deployed to Mali under urgent operational requirements for peacekeeping operations.

Design
The Unibuffel has an enclosed troop compartment and has gun mounts on the front and back to equip it with machine guns. The Typhoon 25mm cannon can also be equipped as a port defense weapon on a flatbed version.

Vehicles were powered by a TATA engine which can deal easily with rough terrain. Bulletproof glass was initially imported from China on a needed basis but later versions use glass manufactured by local suppliers.

Variants
The variants of the Unibuffel consist of following categories,
 Mark I
 Mark II 
 Mark II Improvised Version (Designed and Manufactured for UN Peacekeeping Missions)

Operators

: Known to be used by the Naval Patrolmen.

 Special Task Force: 15 Unibuffels handed to the STF.
