Requests For Adminship
On Wikipedia, trusted users may be appointed as administrators (also referred to as admins, sysops or janitors), following a successful request for adminship. Currently, there are administrators on the English Wikipedia. Administrators have additional technical privileges compared with other editors, such as being able to protect and delete pages and being able to block users from editing pages. On Wikipedia, becoming an administrator is often referred to as "being given r taking upthe mop", a term which has also been used elsewhere. In 2006, ''The New York Times'' reported that administrators on Wikipedia, of whom there were then about 1,000, were "geographically diverse". In July 2012, it was widely reported that Wikipedia was "running out of administrators", because in 2005 and 2006, 40 to 50 people were often appointed administrators each month, but in the first half of 2012, only nine in total were appointed. However, Jimmy Wales, Wikipedia's co-founder, denied that this ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flow Battery
A flow battery, or redox flow battery (after reduction–oxidation), is a type of electrochemical cell where chemical energy is provided by two chemical components dissolved in liquids that are pumped through the system on separate sides of a membrane. Ion transfer inside the cell (accompanied by flow of electric current through an external circuit) occurs through the membrane while both liquids circulate in their own respective space. Cell voltage is chemically determined by the Nernst equation and ranges, in practical applications, from 1.0 to 2.43 volts. The energy capacity is a function of the electrolyte volume and the power is a function of the surface area of the electrodes. A flow battery may be used like a fuel cell (where the spent fuel is extracted and new fuel is added to the system) or like a rechargeable battery (where an electric power source drives regeneration of the fuel). While flow batteries have certain technical advantages over conventional rechargeabl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dry Cell
upLine art drawing of a dry cell: 1. brass cap, 2. plastic seal, 3. expansion space, 4. porous cardboard, 5. zinc can, 6. carbon rod, 7. chemical mixture A dry cell is a type of electric battery, commonly used for portable electrical devices. Unlike wet cell batteries, which have a liquid electrolyte, dry cells use an electrolyte in the form of a paste, and are thus less susceptible to leakage. The dry cell was developed in 1886 by the German scientist Carl Gassner, after development of wet zinc–carbon batteries by Georges Leclanché in 1866. A type of dry cell was also developed by the Japanese Sakizō Yai in 1887. History left, upDry cell battery by Wilhelm Hellesen 1890 Many experimenters tried to immobilize the electrolyte of an electrochemical cell to make it more convenient to use. The Zamboni pile of 1812 is a high-voltage dry battery but capable of delivering only minute currents. Various experiments were made with cellulose, sawdust, spun glass, asbestos fiber ...

Alkaline Batteries
An alkaline battery (IEC code: L) is a type of primary battery where the electrolyte (most commonly potassium hydroxide) has a pH value above 7. Typically these batteries derive energy from the reaction between zinc metal and manganese dioxide, nickel and cadmium, or nickel and hydrogen. Compared with zinc–carbon batteries of the Leclanché cell or zinc chloride types, alkaline batteries have a higher energy density and longer shelf life, yet provide the same voltage. The alkaline battery gets its name because it has an alkaline electrolyte of potassium hydroxide (KOH) instead of the acidic ammonium chloride (NH4Cl) or zinc chloride (ZnCl2) electrolyte of the zinc–carbon batteries. Other battery systems also use alkaline electrolytes, but they use different active materials for the electrodes. Alkaline batteries account for 80% of manufactured batteries in the US and over 10 billion individual units produced worldwide. In Japan, alkaline batteries account for 46% of ...

Lithium-ion Batteries
A lithium-ion or Li-ion battery is a type of rechargeable battery which uses the reversible reduction of lithium ions to store energy. It is the predominant battery type used in portable consumer electronics and electric vehicles. It also sees significant use for grid-scale energy storage and military and aerospace applications. Compared to other rechargeable battery technologies, Li-ion batteries have high energy densities, low self-discharge, and no memory effect (although a small memory effect reported in LFP cells has been traced to poorly made cells). Chemistry, performance, cost and safety characteristics vary across types of lithium-ion batteries. Most commercial Li-ion cells use intercalation compounds as the active materials. The anode or negative electrode is usually graphite, although silicon-carbon is also being increasingly used. Cells can be manufactured to prioritize either energy or power density. Handheld electronics mostly use lithium polymer batteries ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reichenbachfall Funicular
The Reichenbachfall Funicular (german: Reichenbachfall-Bahn; RfB) is a funicular in the Bernese Oberland region of the Switzerland, Swiss canton of Berne. It links Willigen, near Meiringen, with the uppermost of the Reichenbach Falls, famous as the site of the apparent death of Sir Arthur Conan Doyle's fictional hero, Sherlock Holmes. On its route the line follows and crosses the lower falls of the Reichenbach.Richard Green (2007). ''Railways in the Berner Oberland - Part 3''. ''Today's Railways Europe: Issue 134: February 2007''. Platform 5 Publishing Ltd. The funicular was opened in 1899, and was rebuilt in 1999 to the original design. Between 1912 and 1956, it was linked to Meiringen by the Meiringen–Reichenbach–Aareschlucht tramway. Today it is owned by the EWR Energie company, which operates the adjacent hydroelectric power plant, but is maintained by the neighbouring Kraftwerke Oberhasli company, which also operates several other lines in the area. It has the following pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Regional Fishery Body
A regional fishery body (RFB) is a type of international organization that is dedicated to the sustainability of fishery resources in a particular region, or of highly migratory species. An RFB is classified as one of the following two types: * regional fishery management organisation (RFMO) * regional fishery advisory body (RFAB). RFABs issue non-binding recommendations only, but they are usually organised as more independent, impartial expert bodies, expected to be guided by science rather than political interests of its members. RFMOs are in turn more politicised, but their decisions are binding for the members and subject to enforcement. Therefore, the usually science-focused recommendations issued by the relatively independent RFABs often constitute the scientific input to the RMFOs, where they are subject to political negotiations between the members, in order to adjust them to social and economic reality and to translate them into politically acceptable and tenable binding dec ...

RFB Protocol
RFB ("remote framebuffer") is an open simple protocol for remote access to graphical user interfaces. Because it works at the framebuffer level it is applicable to all windowing systems and applications, including Microsoft Windows, macOS and the X Window System. RFB is the protocol used in Virtual Network Computing (VNC) and its derivatives. Description By default, a viewer/client uses TCP port 5900 to connect to a server (or 5800 for browser access), but can also be set to use any other port. Alternatively, a server can connect to a viewer in "listening mode" (by default on port 5500). One advantage of listening mode is that the server site does not have to configure its firewall/NAT to allow access on the specified ports; the burden is on the viewer, which is useful if the server site has no computer expertise, while the viewer user would be expected to be more knowledgeable. Although RFB started as a relatively simple protocol, it has been enhanced with additional features ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Comps (casino)
Comps are complimentary items and services given out by casinos to encourage players to gamble. The amount and quality of comps that a player is given usually depends on what game(s) they play, how much they bet, and how long they play. Most casinos have casino hosts responsible for awarding comps and contacting players to bring them back to the casino. Pit bosses can also award comps at table games. Despite the strategic importance of the comps in the casinos' structure, there is no separate profession for it, in different gambling houses, different specialists may be responsible for it. Most casinos ask players to get a player's club card so their play can be tracked and comps awarded accordingly. Levels The lowest level of comp is free alcohol. Many casinos provide free drinks to anyone gambling. The second level of comp is free self-parking, lounge access, or free meals. Many casinos have several players' lounges and restaurants and might require more play to earn a comp to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roter Frontkämpferbund
The (, translated as "Alliance of Red Front-Fighters" or "Red Front Fighters' League"), usually called (RFB), was a far-left paramilitary organization affiliated with the Communist Party of Germany (KPD) during the Weimar Republic. It was officially a non-partisan and legally registered association. The organisation was banned as extremist by the governing Social Democrats in 1929. The first local branches of the RFB were established in July 1924. The group's inaugural nationwide meeting was held in February 1925 in Berlin, where was elected to lead the federal committee. ('The Red Front') was the newspaper of the RFB. The greeting of ( en, Red Front!) while giving a clenched fist salute gave rise to the expression , often used among friends and foes to refer to the organization instead of its full title. The clenched fist "protecting the friend, fighting off the enemy" (german: „schützend den Freund, abwehrend den Feind“) was the symbol of the RFB, used on all its ...
