Half-Life (series)
''Half-Life'' is a series of first-person shooter (FPS) games developed and published by Valve. The games combine shooting combat, puzzles and storytelling. The original ''Half-Life,'' Valve's first product, was released in 1998 for Windows to critical and commercial success. Players control Gordon Freeman, a scientist who must survive an alien invasion. The innovative scripted sequences were influential on the FPS genre, and the game inspired numerous community-developed mods, including the multiplayer games ''Counter-Strike'' and ''Day of Defeat''. ''Half-Life'' was followed by the expansions ''Opposing Force'' (1999), ''Blue Shift'' (2001) and ''Decay'' (2001), developed by Gearbox Software. In 2004, Valve released ''Half-Life 2'' to further success, with a new setting and characters and physics-based gameplay. It was followed by the extra level ''Lost Coast'' (2005) and the episodic sequels '' Episode One'' (2006) and '' Episode Two'' (2007). The first game in the ''Port ...

Half-life
Half-life (symbol ) is the time required for a quantity (of substance) to reduce to half of its initial value. The term is commonly used in nuclear physics to describe how quickly unstable atoms undergo radioactive decay or how long stable atoms survive. The term is also used more generally to characterize any type of exponential (or, rarely, non-exponential) decay. For example, the medical sciences refer to the biological half-life of drugs and other chemicals in the human body. The converse of half-life (in exponential growth) is doubling time. The original term, ''half-life period'', dating to Ernest Rutherford's discovery of the principle in 1907, was shortened to ''half-life'' in the early 1950s. Rutherford applied the principle of a radioactive element's half-life in studies of age determination of rocks by measuring the decay period of radium to lead-206. Half-life is constant over the lifetime of an exponentially decaying quantity, and it is a characteristic unit for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
House Of Lords
The House of Lords, also known as the House of Peers, is the Bicameralism, upper house of the Parliament of the United Kingdom. Membership is by Life peer, appointment, Hereditary peer, heredity or Lords Spiritual, official function. Like the House of Commons of the United Kingdom, House of Commons, it meets in the Palace of Westminster in London, England. The House of Lords scrutinises Bill (law), bills that have been approved by the House of Commons. It regularly reviews and amends bills from the Commons. While it is unable to prevent bills passing into law, except in certain limited circumstances, it can delay bills and force the Commons to reconsider their decisions. In this capacity, the House of Lords acts as a check on the more powerful House of Commons that is independent of the electoral process. While members of the Lords may also take on roles as government ministers, high-ranking officials such as cabinet ministers are usually drawn from the Commons. The House of Lo ...

Heilongjiang
Heilongjiang () formerly romanized as Heilungkiang, is a province in northeast China. The standard one-character abbreviation for the province is (). It was formerly romanized as "Heilungkiang". It is the northernmost and easternmost province of the country and contains China's northernmost point (in Mohe City along the Amur) and easternmost point (at the junction of the Amur and Ussuri rivers). The province is bordered by Jilin to the south and Inner Mongolia to the west. It also shares a border with Russia (Amur Oblast, Jewish Autonomous Oblast, Khabarovsk Krai, Primorsky Krai and Zabaykalsky Krai) to the north and east. The capital and the largest city of the province is Harbin. Among Chinese provincial-level administrative divisions, Heilongjiang is the sixth-largest by total area, the 15th-most populous, and the second-poorest by GDP per capita. The province takes its name from the Amur River (see the etymology section below for details) which marks the border bet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Headline
The headline or heading is the text indicating the content or nature of the article below it, typically by providing a form of brief summary of its contents. The large type ''front page headline'' did not come into use until the late 19th century when increased competition between newspapers led to the use of attention-getting headlines. It is sometimes termed a news ''hed'', a deliberate misspelling that dates from production flow during hot type days, to notify the composing room that a written note from an editor concerned a headline and should not be set in type. Headlines in English often use a set of grammatical rules known as '' headlinese'', designed to meet stringent space requirements by, for example, leaving out forms of the verb "to be" and choosing short verbs like "eye" over longer synonyms like "consider". Production A headline's purpose is to quickly and briefly draw attention to the story. It is generally written by a copy editor, but may also be written by t ...

Call Signs In Korea
Call signs in Korea are unique identifiers for telecommunications and broadcasting on the Korean peninsula. Call signs are regulated internationally by the ITU as well as nationally in South Korea by the ''Korea Communications Commission'' in the ''Ministry of Information and Communication''. Not much is known outside of North Korea how amateur radio is regulated, although a foreign amateur was asked to appear before the "Radio Regulation Board" in 2002. Also, North Korea's '' Cultural Relations with Foreign Countries'' recently issued an operating permit, which was countermanded by the ''Ministry of Telecommunications and Posts''. Call sign blocks for telecommunication The International Telecommunication Union has assigned the Koreas the following call sign blocks for all radio communication, broadcasting or transmission: While not directly related to call signs, the International Telecommunication Union (ITU) further has divided all countries assigned amateur radio prefixes into ...

Hypotenuse Leg
In geometry, two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other. More formally, two sets of points are called congruent if, and only if, one can be transformed into the other by an isometry, i.e., a combination of rigid motions, namely a translation, a rotation, and a reflection. This means that either object can be repositioned and reflected (but not resized) so as to coincide precisely with the other object. Therefore two distinct plane figures on a piece of paper are congruent if they can be cut out and then matched up completely. Turning the paper over is permitted. In elementary geometry the word ''congruent'' is often used as follows. The word ''equal'' is often used in place of ''congruent'' for these objects. *Two line segments are congruent if they have the same length. *Two angles are congruent if they have the same measure. *Two circles are congruent if they have the s ...

Hydrogen Line
The hydrogen line, 21 centimeter line, or H I line is the electromagnetic radiation spectral line that is created by a change in the energy state of neutral hydrogen atoms. This electromagnetic radiation has a precise frequency of , which is equivalent to the vacuum wavelength of in free space. This frequency falls below the microwave region of the electromagnetic spectrum, which begins at 3.0 GHz (10 cm wavelength), and it is observed frequently in radio astronomy because those radio waves can penetrate the large clouds of interstellar cosmic dust that are opaque to visible light. This line is also the theoretical basis of the hydrogen maser. The microwaves of the hydrogen line come from the atomic transition of an electron between the two hyperfine levels of the hydrogen 1 s ground state that have an energy difference of []. It is called the ''spin-flip transition''. The frequency, , of the quantum, quanta that are emitted by this transition between tw ...

Hotline
A hotline is a point-to-point communications link in which a call is automatically directed to the preselected destination without any additional action by the user when the end instrument goes off-hook. An example would be a phone that automatically connects to emergency services on picking up the receiver. Therefore, dedicated hotline phones do not need a rotary dial or keypad. A hotline can also be called an automatic signaling, ringdown, or off-hook service. For crises and service True hotlines cannot be used to originate calls other than to preselected destinations. However, in common or colloquial usage, a "hotline" often refers to a call center reachable by dialing a standard telephone number, or sometimes the phone numbers themselves. This is especially the case with 24-hour, noncommercial numbers, such as police tip hotlines or suicide crisis hotlines, which are staffed around the clock and thereby give the appearance of real hotlines. Increasingly, however, the te ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hodgkin's Lymphoma
Hodgkin lymphoma (HL) is a type of lymphoma, in which cancer originates from a specific type of white blood cell called lymphocytes, where multinucleated Reed–Sternberg cells (RS cells) are present in the patient's lymph nodes. The condition was named after the English physician Thomas Hodgkin, who first described it in 1832. Symptoms may include fever, night sweats, and weight loss. Often, nonpainful enlarged lymph nodes occur in the neck, under the arm, or in the groin. Those affected may feel tired or be itchy. The two major types of Hodgkin lymphoma are classic Hodgkin lymphoma and nodular lymphocyte-predominant Hodgkin lymphoma. About half of cases of Hodgkin lymphoma are due to Epstein–Barr virus (EBV) and these are generally the classic form. Other risk factors include a family history of the condition and having HIV/AIDS. Diagnosis is conducted by confirming the presence of cancer and identifying RS cells in lymph node biopsies. The virus-positive cases are classified ...
