Tanker may refer to:
A 'tanker (or tank ship or tankship) is a merchant vessel designed to transport liquids or gases in bulk. Major types of tankship include the oil tanker, the chemical tanker, and gas carrier. In the United States Navy and Military Sealift Command, any type of tanker used to refuel other ships is called an oiler
Tankers can range in size of capacity from several hundred tons, which includes vessels for servicing small harbours and coastal settlements, to several hundred thousand tons, for long-range haulage. Besides ocean- or seagoing tankers there are also specialized inland-waterway tankers which operate on rivers and canals with an average cargo capacity up to some thousand tons. A wide range of products are carried by tankers, including:
Tankers are a relatively new concept, dating from the later years of the 19th century. Before this, technology had simply not supported the idea of carrying bulk liquids. The market was also not geared towards transporting or selling cargo in bulk, therefore most ships carried a wide range of different products in different holds and traded outside fixed routes. Liquids were usually loaded in casks—hence the term "tonnage", which refers to the volume of the holds in terms of how many tuns or casks of wine could be carried. Even potable water, vital for the survival of the crew, was stowed in casks. Carrying bulk liquids in earlier ships posed several problems:
Aerial refueling, also referred to as air refueling, in-flight refueling (IFR), air-to-air refueling (AAR), and tanking, is the process of transferring aviation fuel from one military aircraft (the tanker) to another (the receiver) during flight.
The procedure allows the receiving aircraft to remain airborne longer, extending its range or loiter time on station. A series of air refuelings can give range limited only by crew fatigue and engineering factors such as engine oil consumption. Because the receiver aircraft can be topped up with extra fuel in the air, air refueling can allow a takeoff with a greater payload which could be weapons, cargo, or personnel: the maximum takeoff weight is maintained by carrying less fuel and topping up once airborne. Alternatively, a shorter take-off roll can be achieved because take-off can be at a lighter weight before refueling once airborne. Aerial refueling has also been considered as a means to reduce fuel consumption on long distance flights greater than 3,000 nautical miles (5,600 km; 3,500 mi). Potential fuel savings in the range of 35-40% have been estimated for long haul flights (including the fuel used during the tanker missions).
Forum (plural forums or fora) may refer to:
Penthouse Forum, sometimes simply Forum, is a magazine owned by FriendFinder Networks, the publishers of Penthouse magazine.
Penthouse Forum was started in March 1970 as a supplement to Penthouse. Unlike the main Penthouse title, Penthouse Forum is more journalistic than pornographic, and features editorials and opinion pieces on controversial contemporary topics. It features regular monthly columns titled "On the Boards", "On the Beltway", and "On the Edge". It also features a section for the "Letter of the Month".
Alastair Campbell, a journalist and Tony Blair's former Director of Communications, was a contributor to the magazine, as was Chad Varah, the founder of The Samaritans charity and an Anglican priest, who was a consultant on sex education for the magazine.
In July 2006 the rights to the UK edition were licensed to Trojan Publishing.
Forum is a two-hour live call-in radio program produced by KQED-FM, presenting discussions of local, state, national and international issues, and in-depth interviews. The program began in 1990 as a politics-oriented talk show, created and hosted by Kevin Pursglove. Since 1993, it has been hosted by scholar, author, professor, and former KGO Radio host Michael Krasny, who broadened the program's scope to a cross-section of current events.
The format of Forum varies from show to show, but generally involves an in-person interview followed by public Q&A via phone or email with one or more subjects, often nationally prominent authors and scholars. The program airs for two hours on weekday mornings, with an hour repeated in the evening.
