Vitamin C


Vitamin C or L-ascorbic acid is an essential nutrient for humans, in which it functions as a vitamin. Ascorbate (an ion of ascorbic acid) is required for a range of essential metabolic reactions in all animals and plants. It is made internally by almost all organisms; notable mammalian exceptions are most or all of the order chiroptera (bats), and the entire suborder Anthropoidea (Haplorrhini) (tarsiers, monkeys and apes). It is also needed by guinea pigs and some species of birds and fish. Deficiency in this vitamin causes the disease scurvy in humans.It is also widely used as a food additive
The pharmacophore of vitamin C is the ascorbate ion. In living organisms, ascorbate is an anti-oxidant, since it protects the body against oxidative stress, and is a cofactor in several vital enzymatic reactions.
Scurvy has been known since ancient times. People in many parts of the world assumed it was caused by a lack of fresh plant foods. The British Navy started giving sailors lime juice to prevent scurvy in 1795. Ascorbic acid was finally isolated in 1933 and synthesized in 1934. The uses and recommended daily intake of vitamin C are matters of on-going debate, with RDI ranging from 45 to 95 mg/day. Proponents of megadosage propose from 200 to upwards of 2000 mg/day. A recent meta-analysis of 68 reliable antioxidant supplementation experiments, involving a total of 232,606 individuals, concluded that consuming additional ascorbate from supplements may not be as beneficial as thought.

3G


International Mobile Telecommunications-2000 (IMT-2000), better known as 3G or 3rd Generation, is a family of standards for mobile telecommunications defined by the International Telecommunication Union,[1] which includes GSM EDGE, UMTS, and CDMA2000 as well as DECT and WiMAX. Services include wide-area wireless voice telephone, video calls, and wireless data, all in a mobile environment. Compared to 2G and 2.5G services, 3G allows simultaneous use of speech and data services and higher data rates (up to 14.0 Mbit/s on the downlink and 5.8 Mbit/s on the uplink with HSPA+). Thus, 3G networks enable network operators to offer users a wider range of more advanced services while achieving greater network capacity through improved spectral efficiency.
The
International Telecommunication Union (ITU) defined the third generation (3G) of mobile telephony standards – IMT-2000 – to facilitate growth, increase bandwidth, and support more diverse applications. For example, GSM (the current most popular cellular phone standard) could deliver not only voice, but also circuit-switched data at download rates up to 14.4 kbps. But to support mobile multimedia applications, 3G had to deliver packet-switched data with better spectral efficiency, at far greater bandwidths.[dubiousdiscuss]

Constitution


A constitution is a set of rules for government—often codified as a written document—that establishes principles of an autonomous political entity. In the case of countries, this term refers specifically to a national constitution defining the fundamental political principles, and establishing the structure, procedures, powers and duties, of a government. By limiting the government's own reach, most constitutions guarantee certain rights to the people. The term constitution can be applied to any overall law that defines the functioning of a government, including several historical constitutions that existed before the development of modern national constitutions.
Constitutions concern different kinds of political organizations. They are found extensively in regional government, at supranational (e.g., European Union), federal (e.g., Indian Constitution), state or provincial (e.g., the constitution of the Commonwealth of Massachusetts or the constitution of the State of New York), and sub-national levels. They are also found in many political groups, such as political parties, pressure groups, and trade unions.
Non-political entities such as corporations and voluntary associations, whether incorporated or not, may also have a constitution. The constitution of a legally incorporated entity is more usually styled as its memorandum and articles of association (U.S. incorporation).
Constitution of India is the longest written constitution of any sovereign country in the world, containing 448 articles, 12 schedules and 94 amendments, thereby totaling 117,369 words in its English language version.


Etymology

The term constitution comes from a Latin term denoting an important law, usually one proclaimed by the Roman emperor ("constitutiones principis": the edicta, mandata, decrera and rescripta). Later, the term was widely used in canon law for an important determination, especially by the Pope, which are now referred to as apostolic constitutions
