Vác
Vác (; ; ; ) is a thousand-year old city in Pest county in Hungary with approximately 35,000 inhabitants. The archaic spelling of the name is ''Vácz''. Location Vác is located north of Budapest on the eastern bank of the Danube river, below the bend where the river changes course and flows south. The town is seated at the foot of the Naszály Mountain in the foothills of the Carpathian Mountains, Carpathians. Modern Vác Vác is a commercial center as well as a popular summer resort for citizens of Budapest. The Vác Cathedral, built 1761–1777, was modelled after St. Peter's Basilica in Rome. The Bishop, episcopal palace houses a museum for Roman and medieval artifacts. The city is also known for its 18th-century arch of triumph and for its beautiful baroque city center. History Settlement in Vác dating as far back as the Roman Empire has been found. The origin of its name is debated. One hypothesis says that the name comes from a Hungarian tribal name "Vath". It has bee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Doctor Of Technology
The Doctor of Technology, or Doctor of Engineering Sciences, or Doctor of Technical Sciences, or Doctor of Science (abbreviated and translated variously in different countries) is a degree normally conferred upon candidates after having completed a course of study in technology and a dissertation or a project of lengthy duration in a technologically related field. Like other doctorates, it is usually an academic degree at the highest level equivalent to a PhD. While the details of the degree vary, a doctor of technology program usually enables graduates to obtain an advanced level of knowledge in specialist fields and aims to produce graduates capable of advancing knowledge within their industry. The degree focuses on developing practical solutions in the workplace, critical analysis, synthesis, and innovation. As a substantive degree In Austria, universities of technology, such as TU Wien, grant the title of "Dr.techn." (in German: "Doktor der technischen Wissenschaften" which tra ...

Hungarian Parliamentary Election, 1994
Parliamentary elections were held in Hungary on 8 May 1994, with a second round of voting in 174 of the 176 single member constituencies on 29 May.Dieter Nohlen & Philip Stöver (2010) ''Elections in Europe: A data handbook'', p899 Nohlen & Stöver, p925 They resulted in the return to power of the Hungarian Socialist Party, the former Communist party, under the leadership of Gyula Horn, who became prime minister. The Socialists achieved a remarkable revival, winning an overall majority of 209 seats out of 386, up from 33 in 1990. The governing Hungarian Democratic Forum was severely defeated, falling from 165 seats to 38 for third place. It was also a disappointment for the principal opposition party of the previous parliament, the Alliance of Free Democrats, which failed to capitalize on the government's unpopularity and lost seats. Poor economic performance, apparent government incompetence and a certain nostalgia for the social security of the communist era appear to be the mai ...

National Democratic Alliance (Hungary)
The National Democratic Alliance (; NDSZ) was a short-lived centre-left party in Hungary, founded and led by Zoltán Bíró and Imre Pozsgay, defectors from the Hungarian Democratic Forum (MDF) and the Hungarian Socialist Party (MSZP), respectively. History The NDSZ was formed on 17 May 1991 by intellectuals from both left–right political spectrum, including Sándor Sára, Barna Tálas, Sándor Püski, István Kukorelli and András Mezei. By 1993, in addition to Pozsgay, three other Members of Parliament; Kata Beke, a former Political Secretary of State of Education, Péter Szél and Zoltán Varga had joined the party, all of them from the MDF. The party wanted to retain the spirit of the Hungarian Round Table Talks and the Lakitelek meeting, the benefits of peaceful democratic change. The NDSZ had a third way The Third Way is a predominantly centrist political position that attempts to reconcile centre-right and centre-left politics by advocating a varying synthesis of ...

Hungarian Parliamentary Election, 1990
Parliamentary elections were held in Hungary on 25 March 1990, with a second round of voting taking place in all but five single member constituencies on 8 April. They were the first completely free and competitive elections to be held in the country since 1945, and only the second completely free elections with universal suffrage in the country's history. The conservative, nationalist Hungarian Democratic Forum (MDF) beat the liberal and more internationalist Alliance of Free Democrats, which had spearheaded opposition to Communist rule in 1989, to become the largest party in parliament. The Hungarian Socialist Party, the former Communist party, suffered a crushing defeat, winning only 33 seats for fourth place. MDF leader József Antall became prime minister in coalition with the Christian Democratic People's Party and Independent Smallholders' Party. It was the first government since the end of World War II with no Communist participation. Background Hungary's trans ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alliance For The Protection Of Nature And Society
The Alliance for the Protection of Nature and Society (; TTVSZ), was a political party in Hungary between 1990 and 1995. History The TTVSZ was founded in January 1990 by biochemist and ''Természet Világa'' editor-in-chief Tibor Gánti, who also led the party as President of the Coordination Board. The party contested in the 1990 parliamentary election with two individual candidates, who received 0.03 percent of the votes, gaining no seats. Nohlen, D & Stöver, P (2010) ''Elections in Europe: A data handbook'', p. 899. The TTVSZ did not participate solely in the 1994 parliamentary election, its leader Gánti ran as a candidate on the national list of the National Democratic Alliance The National Democratic Alliance (NDA; ISO 15919, ISO: ''Rāṣṭrīya Lokatāntrik Gaṭhabandhan'') is an Indian big tent Political group, multi-party political alliance, led by the country's biggest political party, the Bharatiya Janata Pa ..., but did not obtain a mandate.

Unit Of Selection
A unit of selection is a biological entity within the hierarchy of biological organization (for example, an entity such as: a self-replicating molecule, a gene, a cell, an organism, a group, or a species) that is subject to natural selection. There is debate among evolutionary biologists about the extent to which evolution has been shaped by selective pressures acting at these different levels.Okasha, S. (2006) ''Evolution and the levels of selection''. Oxford University Press. There is debate over the relative importance of the units themselves. For instance, is it group or individual selection that has driven the evolution of altruism? Where altruism reduces the fitness of ''individuals'', individual-centered explanations for the evolution of altruism become complex and rely on the use of game theory, for instance; see kin selection and group selection. There also is debate over the definition of the units themselves, and the roles for selection and replication, and whether ...

Origin Of Life
Abiogenesis is the natural process by which life arises from abiotic component, non-living matter, such as simple organic compounds. The prevailing scientific hypothesis is that the transition from non-living to organism, living entities on Earth was not a single event, but a process of increasing complexity involving the formation of a planetary habitability, habitable planet, the prebiotic synthesis of organic molecules, molecular self-replication, self-assembly, autocatalysis, and the emergence of cell membranes. The transition from non-life to life has never been observed experimentally, but many proposals have been made for different stages of the process. The study of abiogenesis aims to determine how pre-life chemical reactions gave rise to life under conditions strikingly different from those on Earth today. It primarily uses tools from biology and chemistry, with more recent approaches attempting a synthesis of many sciences. Life functions through the specialized ch ...

Cell Membrane
The cell membrane (also known as the plasma membrane or cytoplasmic membrane, and historically referred to as the plasmalemma) is a biological membrane that separates and protects the interior of a cell from the outside environment (the extracellular space). The cell membrane consists of a lipid bilayer, made up of two layers of phospholipids with cholesterols (a lipid component) interspersed between them, maintaining appropriate membrane fluidity at various temperatures. The membrane also contains membrane proteins, including integral proteins that span the membrane and serve as membrane transporters, and peripheral proteins that loosely attach to the outer (peripheral) side of the cell membrane, acting as enzymes to facilitate interaction with the cell's environment. Glycolipids embedded in the outer lipid layer serve a similar purpose. The cell membrane controls the movement of substances in and out of a cell, being selectively permeable to ions and organic mole ...

Self-replication
Self-replication is any behavior of a dynamical system that yields construction of an identical or similar copy of itself. Biological cells, given suitable environments, reproduce by cell division. During cell division, DNA is replicated and can be transmitted to offspring during reproduction. Biological viruses can replicate, but only by commandeering the reproductive machinery of cells through a process of infection. Harmful prion proteins can replicate by converting normal proteins into rogue forms. Computer viruses reproduce using the hardware and software already present on computers. Self-replication in robotics has been an area of research and a subject of interest in science fiction. Any self-replicating mechanism which does not make a perfect copy (mutation) will experience genetic variation and will create variants of itself. These variants will be subject to natural selection, since some will be better at surviving in their current environment than others and will o ...

Metabolism
Metabolism (, from ''metabolē'', "change") is the set of life-sustaining chemical reactions in organisms. The three main functions of metabolism are: the conversion of the energy in food to energy available to run cellular processes; the conversion of food to building blocks of proteins, lipids, nucleic acids, and some carbohydrates; and the elimination of metabolic wastes. These enzyme-catalyzed reactions allow organisms to grow and reproduce, maintain their Structures#Biological, structures, and respond to their environments. The word ''metabolism'' can also refer to the sum of all chemical reactions that occur in living organisms, including digestion and the transportation of substances into and between different cells, in which case the above described set of reactions within the cells is called intermediary (or intermediate) metabolism. Metabolic reactions may be categorized as ''catabolic''—the ''breaking down'' of compounds (for example, of glucose to pyruvate by c ...
