Network Of International Christian Schools
The Network of International Christian Schools (NICS) is an organization that consists of 15 schools in 13 countries in Asia, Africa, South America, Europe and includes an online school in North America. There are plans in the works for more schools in the near future. History In 1983, Joe Hale, his wife Ann, and some other missionaries formed Liberty Christian School ( International Christian School) in South Korea. They initially anticipated that this school would educate about 30 students, but on the school’s inaugural day 83 students arrived for classes. The school continued to grow, and currently there are three NICS schools in South Korea with a total enrollment of over 1200 students. It quickly became apparent that the need for international schools, particularly Christian ones, was present in many countries beyond Korea. Schools perpetuating the same approach soon appeared in other countries and on other continents. The vast growth of the initial schools was such that ...

National Instant Criminal Background Check System
The National Instant Criminal Background Check System (NICS) is a background check system in the United States created by the Brady Handgun Violence Prevention Act (Brady Law) of 1993 to prevent firearm sales to people prohibited under the Act. The system was launched by the Federal Bureau of Investigation (FBI) in 1998. Under the system, firearm dealers, manufacturers or importers who hold a Federal Firearms License (FFL) are required to undertake a NICS background check on prospective buyers before transferring a firearm. The NICS is not a gun registry, but is a list of persons prohibited from owning or possessing a firearm. The buyer’s details are discarded after the query and a record on NICS of the firearm purchase is not made, though the seller as a FFL holder is required to keep a record of the transaction. Access to NICS is limited to FFL holders. A prospective buyer is required to complete ATF Form 4473 after which a FFL seller initiates a NICS background check by phon ...

Northern Ireland Civil Service
The Northern Ireland Civil Service (NICS; ga, Státseirbhís Thuaisceart Éireann; Ulster Scots dialects, Ulster-Scots: ''Norlin Airlann Cïvil Sarvice'') is the permanent bureaucracy of employees that supports the Northern Ireland Executive, the devolved government of Northern Ireland. The NICS is one of three civil services in the United Kingdom, the others being the Civil Service (United Kingdom), Home Civil Service and Her Majesty's Diplomatic Service, HM Diplomatic Service. The heads of these services are members of the Permanent Secretaries Management Group. History 1921–1972 Northern Ireland was established by the Government of Ireland Act 1920 and the first devolved Parliament of Northern Ireland took office on 7 June 1921. The first civil servants were transferred from the Irish civil service (pre-independence), Irish civil service headquartered at Dublin Castle. The departments of the Executive Committee of the Privy Council of Northern Ireland, Northern Ir ...

Nucleus-independent Chemical Shift
An aromatic ring current is an effect observed in aromatic molecules such as benzene and naphthalene. If a magnetic field is directed perpendicular to the plane of the aromatic system, a ring current is induced in the delocalized π electrons of the aromatic ring. This is a direct consequence of Ampère's law; since the electrons involved are free to circulate, rather than being localized in bonds as they would be in most non-aromatic molecules, they respond much more strongly to the magnetic field. The ring current creates its own magnetic field. Outside the ring, this field is in the same direction as the externally applied magnetic field; inside the ring, the field counteracts the externally applied field. As a result, the net magnetic field outside the ring is greater than the externally applied field alone, and is less inside the ring. Aromatic ring currents are relevant to NMR spectroscopy, as they dramatically influence the chemical shifts of 1H nuclei ("protons") in ...

National Insurance
National Insurance (NI) is a fundamental component of the welfare state in the United Kingdom. It acts as a form of social security, since payment of NI contributions establishes entitlement to certain state benefits for workers and their families. Introduced by the National Insurance Act 1911 and expanded by the Labour government in 1948, the system has been subjected to numerous amendments in succeeding years. Initially, it was a contributory form of insurance against illness and unemployment, and eventually provided retirement pensions and other benefits. Currently, workers pay contributions from the age of 16 years, until the age they become eligible for the State pension. Contributions are due from employed people earning at or above a threshold called the Lower Earnings Limit, the value of which is reviewed each year. Self-employed people contribute partly through a fixed weekly or monthly payment and partly on a percentage of net profits above a threshold, which is revi ...

National Institute For Computational Sciences
The National Institute for Computational Sciences (NICS) is funded by the National Science Foundation and managed by the University of Tennessee. NICS was home to Kraken, the most powerful computer in the world managed by academia. The NICS petascale scientific computing environment is housed at Oak Ridge National Laboratory (ORNL), home to the world's most powerful computing complex. The mission of NICS, a member of the Extreme Science and Engineering Discovery Environment (XSEDE - formerly TeraGrid), is to enable the scientific discoveries of researchers nationwide by providing leading-edge computational resources, together with support for their effective use, and leveraging extensive partnership opportunities. Systems Kraken Kraken was the University of Tennessee’s petascale computing environment funded by the NSF and fully integrated with XSEDE formerly TeraGrid XD. Kraken was a 1.17-petaflop Cray XT5 system containing 18,816 compute sockets and more than 147 terabytes o ...
