European Parliamentary Technology Assessment
The European Parliamentary Technology Assessment (EPTA) is a network of technology assessment (TA) institutions specialising in advising parliamentary bodies in Europe. Objectives The EPTA partners advise parliaments on the possible social, economic and environmental impact of new sciences and technologies. The common aim is to provide impartial and high quality analysis and reports of developments in issues such as for example bioethics and biotechnology, public health, environment and energy, ICTs, and R&D policy. Such work is seen as an aid to the democratic control of scientific and technological innovations, and was pioneered in the 1970s by the Office of Technology Assessment (OTA) of the US Congress. EPTA aims to advance the establishment of technology assessment (TA) as an integral part of policy formation in parliamentary decision-making processes in Europe, and to strengthen the links between TA units in Europe. History and organization The EPTA network was formall ...

European Pulsar Timing Array
The European Pulsar Timing Array (EPTA) is a European collaboration to combine five 100-m class radio-telescopes to observe an array of pulsars with the specific goal of detecting gravitational waves. It is one of three pulsar timing array projects in operation, the others being the Parkes Pulsar Timing Array and the North American Nanohertz Observatory for Gravitational Waves. Pulsars and high-precision timing Pulsars are rapidly rotating, highly magnetised neutron stars that emit radio waves from their magnetic poles that are, due to the star's rotation, observed on Earth as a string of pulses. Due to the extremely high density of neutron stars, their rotation periods are very stable, hence the observed arrival time of the pulses are highly regular. These arrival times are called TOAs (time of arrival) and can be used to perform high-precision timing experiments. The stability of the TOAs from most pulsars is limited due to the presence of red noise, also called "timing noise" ...

Phosphotungstic Acid
Phosphotungstic acid (PTA) or tungstophosphoric acid (TPA), is a heteropoly acid with the chemical formula . It forms hydrates . It is normally isolated as the ''n'' = 24 hydrate but can be desiccated to the hexahydrate (''n'' = 6). EPTA is the name of ethanolic phosphotungstic acid, its alcohol solution used in biology. It has the appearance of small, colorless-grayish or slightly yellow-green crystals, with melting point 89 °C (24 hydrate). It is odorless and soluble in water (200 g/100 ml). It is not especially toxic, but is a mild acidic irritant. The compound is known by a variety of names and acronyms (see 'other names' section of infobox). In these names the "12" or "dodeca" reflects the fact that the anion contains 12 tungsten atoms. Some early workers who did not know the structure called it phospho-24-tungstic acid, formulating it as 3H2O·P2O5 24WO3·59H2O, , which correctly identifies the atomic ratios of P, W and O. This formula was still quoted in papers as late ...

Expanded Programme Of Technical Assistance
The United Nations Development Programme (UNDP)french: Programme des Nations unies pour le développement, PNUD is a United Nations agency tasked with helping countries eliminate poverty and achieve sustainable economic growth and human development. Headquartered in New York City, it is the largest UN development aid agency, with offices in 170 countries. The UNDP emphasizes developing local capacity towards long-term self-sufficiency and prosperity. It administers projects to attract investment, technical training, and technological development, and provides experts to help build legal and political institutions and expand the private sector. The UNDP operates in 177 countries and is funded entirely by voluntary contributions from UN member states. Also, UNDP is governed by a 36-member executive board overseen by an administrator, who is third-highest ranking UN official after the Secretary-General and Deputy Secretary-General. Founding The UNDP was founded on 22 Novem ...
