Area of Critical Environmental Concern (Massachusetts)
The Massachusetts Area of Critical Environmental Concern Program is a list of state-designated places within the Commonwealth that receive special attention due to their natural and cultural resources. The program was established in 1975 and includes a list of thirty ACECs covering over 268,000 acres in seventy six communities throughout the state; the ACEC Program is administered by the Department of Conservation and Recreation on behalf of the Secretary of Energy and Environmental Affairs
Area of Critical Environmental Concern
Areas of Critical Environmental Concern is a conservation ecology program in the Western United States, managed by the Bureau of Land Management. The ACEC program was conceived in the 1976 Federal Lands Policy and Management Act, which established the first conservation ecology mandate for the BLM; the FLPMA mandate directs the BLM to protect important riparian corridors and endangered species habitats and archeological resources and unique scenic landscapes that the agency assesses as in need of special management attention. To be considered a potential ACEC an area must meet criteria of both importance. An area meets the relevance criteria of an ACEC if it contains one or more of the following: A significant historic, cultural, or scenic value. A fish or wildlife resource. A natural process or system Natural hazards An area meets the importance criteria if it is characterized by one or more of the following: Has more than locally significant qualities. Has qualities or circumstances that make it fragile, irreplaceable, unique, etc.
Has been recognized as warranting protection to satisfy national priority concerns or to carry out the mandates of the Federal Land Policy and Management Act. Has qualities which warrant concern about safety and public welfare. Poses a significant threat to human life and safety, or to property.

Australian Computers in Education Conference
This National Conference is the biennial conference of the Australian Council for Computers in Education. The conference brings together educators from across Australia and around the world who are interested in the use of information and communication technologies to support and enhance teaching and learning in school classrooms, as opposed to a focus on its use in higher education, or school administration. Affiliate member organisations of ACCE take turns to host the national conference, in place of their own state conference; the affiliates are: TASITE - Tasmanian society for IT in Education DLTV - ICT in Education Victoria ICTENSW - ICT in Education New South Wales QSITE - Queensland Society for IT in Education ITEANT - IT Educators Association of the Northern Territory EdTEchSA - South Australia ECAWA - Educational Computing Association of Western Australia The first conference took place in Melbourne in 1983. Since that time it has continued to provide teachers around the country a forum to exchange information on classroom activity, make connections with each other, learn from experts in the field.
The conference proceedings provide an insight into the nature of educational computing practice since the early 1980s and the papers are cited in the research field literature. In 2008 the conference was held in Canberra and the Education Minister Julia Gillard delivered the opening Keynote Address, highlighting the importance of digital technologies in her education reform agenda. 2016: Brisbane, theme: IF 2014: Adelaide, theme: Now ITs Personal.

Ateliers de Constructions Electriques de Charleroi
SA Ateliers de Constructions Electriques de Charleroi was a Belgian manufacturer of electrical generation, transport and industrial equipment, with origins dating to the late 19th century as a successor to the Société Électricité et Hydraulique founded by Julien Dulait. After World War II the company expanded into electronics, became a contractor to the nuclear industry; the company was acquired by Westinghouse in 1970. The company operated at a loss during the 1980s, was split and sold; the remnants of the company were merged into Union Minière in 1989. In 1878 Julien Dulait, son of steelworks engineer Jules Dulait began experiments into electrical and hydraulic machines. In 1881 the Compagnie générale d'Electricité was formed in Charleroi with Dulait as consulting engineer, constructing machines to Dulait's designs and those of Zénobe Gramme. In 1886 the company was renamed becoming Société anonyme Électricité et Hydraulique à Charleroi, by this time the factory was producing dynamos with over 100 kW power.
By 1900 the company had supplied electric lighting to the cities of Liege and Schaerbeek, opened a new 50 ha factory in Marcinelle/Marchienne. In 1904 the company supplied trams for a line in Cointe, Liege- - the first Belgian built trams; the company's product range included dynamos, carbon arc lamps, electric traction motors for trams and drilling equipment. In 1898, the company established a factory in France in Jeumont. On 7 July 1904, the company became Ateliers de Constructions électriques de Charleroi, having been acquired by Baron Edouard Empain; the Jeumont, France factory was renamed Ateliers de constructions électriques du Nord et de l'Est in 1906. After foundation in 1904 the company expanded in the next decade, establishing several new factories including ones for electrical cables and tool making, large scale machines. In 1914 the company began manufacturing motor vehicles, with an electric transmission system, to the design of Balachowsky & Caire. During World War I the factory was stripped of machines by occupying German forces.
In the interwar period ACEC began to produce vacuum-based electronics, including mercury arc rectifiers - in 1929 mercury-arc retifiers were installed on Bruxelles tram system replacing rotary converters. The company produced a high-power test installation, capable of producing 2.5GW in short circuit, with currents and voltages of up to 267kA and 250kV. In 1939 ACEC began to collaborate with Constructions Electriques de Belgique, with the two companies rationalising their combined production. During the buildup to World War II the factory was commissioned to manufacture 75mm anti-aircraft guns, 47mm antitank guns and other weapons, as well as variable-pitch propellers and parts for Hispano-Suiza aircraft. After the outbreak of war preparations were made to relocate the factories - some production was restarted at a Hispano-Suiza factory near Tarbes, France; the Charleroi plant was taken under the control of the German armed forces. By 1942 raw materials, manufactured parts and tools were beginning to become scarce, in 1942/2 workers at the plant began to be commandeered to work in factories in Germany those of AEG, Siemens and Brown-Boveri.
In 1947 the collaboration with CEB concluded with the two companies forming ACEC Herstal. ACEC acted as a contractor and equipment supplier to the nuclear industry, supplying sensor and handling systems including fuel rod handling, pumps for coolant systems and instrumentation, as well as conventional power plant equipment such as main generators, control systems and computer systems. In 1957, the company entered into a licensing arrangement with Westinghouse relating to PWR reactors. In the three decades after World War II the company expanded into the electronics industry, starting to manufacture products including tape recorders and radios; the Société Electro Meccanique was absorbed in 1960/1. In 1970, it became a member of the Westinghouse group. Over the next two decades the company was restructured and its various operations sold off; the ACEC cable factory was split as a separate company câblerie de Charleroi in 1971, acquired by Compagnie Générale d'Electricité in 1986, as of 2012 a factory in Charleroi is part of Nexans Benelux and manufacturers medium and high voltage electric cable.
Westinghouse reduced its shareholding to less than 50% by the late 1970s,In 1985 Inductotherm Industries acquired four induction heating businesses from ACEC, including Elphiac. The Société Générale de Belgique and Compagnie générale d'électricité agreed to acquire Westinghouse's share in the company in 1985, becoming joint majority shareholders; the company restructured in the 1980s, reducing its workforce from over 5000 in 1985 to 2200 in 1998. The company reported losses of over 4 billion Belgian francs in 1986, over 500million loss in 1987. In 1988 the company was still in poor financial condition.
International Electrotechnical Commission
The International Electrotechnical Commission is an international standards organization that prepares and publishes International Standards for all electrical and related technologies – collectively known as "electrotechnology". IEC standards cover a vast range of technologies from power generation and distribution to home appliances and office equipment, fibre optics, solar energy and marine energy as well as many others; the IEC manages three global conformity assessment systems that certify whether equipment, system or components conform to its International Standards. The IEC charter embraces all electrotechnologies including energy production and distribution, electronics and electromagnetics, multimedia, telecommunication and medical technology, as well as associated general disciplines such as terminology and symbols, electromagnetic compatibility and performance, dependability and development, safety and the environment; the first International Electrical Congress took place in 1881 at the International Exposition of Electricity, held in Paris.
At that time the International System of Electrical and Magnetic Units was agreed to. The International Electrotechnical Commission held its inaugural meeting on 26 June 1906, following discussions among the British Institution of Electrical Engineers, the American Institute of Electrical Engineers, others, which began at the 1900 Paris International Electrical Congress, continued with Colonel R. E. B. Crompton playing a key role. In 1906, Lord Kelvin was elected as the first President of the International Electrotechnical Commission; the IEC was instrumental in developing and distributing standards for units of measurement the gauss and weber. It first proposed a system of standards, the Giorgi System, which became the SI, or Système International d’unités. In 1938, it published a multilingual international vocabulary to unify terminology relating to electrical and related technologies; this effort continues, the International Electrotechnical Vocabulary remains an important work in the electrical and electronic industries.
The CISPR – in English, the International Special Committee on Radio Interference – is one of the groups founded by the IEC. 82 countries are members while another 82 participate in the Affiliate Country Programme, not a form of membership but is designed to help industrializing countries get involved with the IEC. Located in London, the commission moved to its current headquarters in Geneva in 1948, it has regional centres in Latin America and North America. Today, the IEC is the world's leading international organization in its field, its standards are adopted as national standards by its members; the work is done by some 10,000 electrical and electronics experts from industry, academia, test labs and others with an interest in the subject. IEC standards have numbers in the range 60000–79999 and their titles take a form such as IEC 60417: Graphical symbols for use on equipment. Following the Dresden Agreement with CENELEC the numbers of older IEC standards were converted in 1997 by adding 60000, for example IEC 27 became IEC 60027.
Standards of the 60000 series are found preceded by EN to indicate that the IEC standard is adopted by CENELEC as a European standard. The IEC cooperates with the International Organization for Standardization and the International Telecommunication Union. In addition, it works with several major standards development organizations, including the IEEE with which it signed a cooperation agreement in 2002, amended in 2008 to include joint development work. Standards developed jointly with ISO such as ISO/IEC 26300, ISO/IEC 27001, CASCO ISO/IEC 17000 series, carry the acronym of both organizations; the use of the ISO/IEC prefix covers publications from ISO/IEC Joint Technical Committee 1 - Information Technology, as well as conformity assessment standards developed by ISO CASCO and IEC CAB. Other standards developed in cooperation between IEC and ISO are assigned numbers in the 80000 series, such as IEC 82045-1. IEC standards are being adopted by other certifying bodies such as BSI, CSA, UL & ANSI/INCITS, SABS, SAI, SPC/GB and DIN.
IEC standards adopted by other certifying bodies may have some noted differences from the original IEC standard. The IEC is made up of members, called national committees, each NC represents its nation's electrotechnical interests in the IEC; this includes manufacturers, providers and vendors, consumers and users, all levels of governmental agencies, professional societies and trade associations as well as standards developers from national standards bodies. National committees are constituted in different ways; some NCs are public sector only, some are a combination of public and private sector, some are private sector only. About 90% of those who prepare IEC standards work in industry. IEC Member countries include: Source: In 2001 and in response to calls from t
