Belairbus. Belairbus is a Belgian aerospace manufacturer. It is a consortium established to allow a number of Belgian companies to participate in the manufacturing of Airbus aircraft while fulfilling Airbus' stipulation that it only deal with one entity in each European country that wants to be a part of the Airbus manufacturing program. It is an associated partner of Airbus, manufacturing parts for the Airbus A320 family, the Airbus A340 and the Airbus A380.

History

Belairbus was formed in 1979 as a consortium of the Belgian government; the development authority of Wallonia; and the companies SONACA (formerly Avions Fairey), Fabrique Nationale and Asco. The consortium was established to participate in manufacturing the Airbus A310, being responsible for A310 wing leading edge slats, slat tracks and Krueger flaps. Airbus called Belairbus an "associate", along with Fokker, as both companies were involved with manufacturing Airbus aircraft without being shareholders in Airbus.

The consortium partners are now Sonaca, Asco Industries and Eurair, a subsidiary of Watteeuw Group. Belairbus subcontracts manufacturing to these three consortium members. Each consortium member's share in Belairbus is in proportion to the value of its production for the consortium; Sonaca's share is approximately 58%, Asco's 35%, and Eurair's 7%, with a single share also held by Belgian aerospace company SABCA.

Bismole. Bismole is a theoretical heterocyclic organic compound, a five-membered ring with the formula C4H4BiH. It is classified as a metallole. It can be viewed as a structural analog of pyrrole, with bismuth replacing the nitrogen atom of pyrrole. The unsubstituted compound has not been isolated due to the high energy of the Bi-H bond. Substituted derivatives, which have been synthesized, are called bismoles.

Reactions
2,5-Bis(trimethylsilyl)-3,4-dimethyl-1-phenyl-1H-bismole, for example, can be formed by the reaction of (1Z,3Z)-1,4-bis(trimethylsilyl)-1,4-diiodobuta-2,3-dimethyl-1,3-diene and diiodophenylbismuthine. Bismoles can be used to form ferrocene-like sandwich compounds.

Intersect (video game). Intersect, known as Digidrive in North America and Japan, is a puzzle video game developed by Q-Games and published by Nintendo for the Game Boy Advance in 2006 exclusively in Japan. It is the only game in the bit Generations series to not be developed by Skip Ltd. It was later re-released for the Nintendo DSi's DSiWare digital distribution service, where it was released outside Japan for the first time.

The inspiration came from the police direction of the floats during the Gion Festival in Kyoto.

Gameplay
The objective of the game is to propel the disc-shaped corevto as many meters as possible before the piston collides into the core and ends the game. The player must direct up to three different varieties of "vehicle," each of a different color, into one of four different lanes. If five of the same vehicle fill up the same lane, a triangle will appear and the lane will change to the same color as the type of vehicle that entered this lane.

Once the player get all five cars of the same color in all four directions, it results in an overdrive, where they can send vehicles of their color in the direction of that color before the color in that direction goes away, but once the vehicle goes in the right direction, it fills that direction up.  Overdrive ends when either a vehicle goes in the direction that does not match the color, or if a direction did not have a vehicle of that color in that direction in the last few seconds.

Reception

Intersect has received a score of 83/100 on Metacritic based on 6 reviews, indicating "generally favorable" reviews.

Northwest Power and Conservation Council. The Northwest Power and Conservation Council is a regional organization that develops and maintains a regional power plan and a fish and wildlife program to balance the Northwest's environment and energy needs. Based in Portland, Oregon, the Council was created in 1980 when the U.S. Congress passed the Pacific Northwest Electric Power Planning and Conservation Act. The council's main task is to develop a 20-year electric power plan that will guarantee adequate and reliable energy at the lowest economic and environmental cost to the Northwest. Member states of the organization are Idaho, Montana, Oregon, and Washington.

Power plan
The council updates the 20-year electric power plan every five years. The process relies on broad public participation to inform the plan and build consensus on its recommendations. The plan generally targets energy efficiency and predicts that a large percentage of the new demand for electricity over the next 20 years in the Northwestern United States can be met by using energy more efficiently. The sixth plan was unanimously approved by the council on February 10, 2010.

Fish and wildlife
The council updates a fish and wildlife plan about every five years. As a planning, policymaking and reviewing body, the Council develops the program, and then monitors its implementation by the Bonneville Power Administration, the United States Army Corps of Engineers, the United States Bureau of Reclamation, and the Federal Energy Regulatory Commission and its licensees. The Northwest Power Act directs the council to develop its program and make periodic major revisions by first requesting recommendations from the region’s federal and state fish and wildlife agencies, appropriate Indian tribes (those within the basin) and other interested parties. The council also takes comment from designated entities and the public on those recommendations. The council then issues a draft amended program, initiating an extensive public comment period on the recommendations and proposed program amendments that includes extensive written comments, public hearings in each of the four states, and consultations with interested parties.

Standard Gibbs free energy of formation. The standard Gibbs free energy of formation (Gf°) of a compound is the change of Gibbs free energy that accompanies the formation of 1 mole of a substance in its standard state from its constituent elements in their standard states (the most stable form of the element at 1 bar of pressure and the specified temperature, usually 298.15 K or 25 °C).

The table below lists the standard Gibbs function of formation for several elements and chemical compounds and is taken from Lange's Handbook of Chemistry. Note that all values are in kJ/mol.  Far more extensive tables can be found in the CRC Handbook of Chemistry and Physics and the NIST JANAF tables.  The NIST Chemistry WebBook (see link below) is an online resource that contains standard enthalpy of formation for various compounds along with the standard absolute entropy for these compounds from which the standard Gibbs free energy of formation can be calculated.

Neutron-acceptance diagram shading. Neutron-acceptance diagram shading (NADS) is a beam simulation technique.  Unlike Monte-Carlo simulation codes like McStas, NADS does not trace individual neutrons but traces linearly-related bunches in a reduced-dimensionality phase space.  Bunches are subdivided where necessary to follow accurately a simplified surface reflectivity model.  This makes jnads results equivalent to Monte-Carlo simulations but about 5 orders of magnitude faster for difficult modelling tasks.

Speed
The raw speed of NADS makes it a particularly attractive tool for beam modelling where evolutionary algorithms are used.  Tests on the C++ prototype engine could calculate the on-sample flux of a SANS instrument in 55 milliseconds on a single 2 GHz intel core 2 core.  The java release (jnads) performs the same calculation in 0.8 seconds on the same hardware.  A Monte-Carlo simulation of the same instrument would take 25 hours to complete with 1% statistical errors.

Performing the same, unoptimised SANS simulation with full beam monitors in jnads (i.e. not just calculating the on-sample flux) takes about 45 seconds on the same hardware and gives you an idea of the beam divergence and homogeneity at the same time.

Reliability
NADS results are generally in excellent agreement with Monte-Carlo calculations.  In strictly controlled tests, NADS and Monte-Carlo both produced identical results when simulating a SANS instrument.  To date, no discrepancy has been found.

Limitations
It's strictly monochromatic (but you can get away with a 15% spread typical of velocity selectors)
Your instrument must have independent horizontal and vertical planes. No crosstalk.
Polarisation and time-of-flight are further complications that users have to consider manually. It's not a black box technique

NADS provides the neutron flux.  To calculate the neutron beam current NADS result must be multiplied by the wavelength band width.

History
NADS was born out of necessity.  If simulating an instrument takes more than one CPU-day, then performing a full optimisation of a neutron guide hall requires more than two CPU-decades.  NADS was designed with the goal of reducing the CPU time to less than one minute for all instrument geometries, making an optimisation of a neutron guide hall feasible within a week on a single desktop computer.

The name NADS arose partly due to referee comments on the original article (ADS is already used widely in Astronomy, the authors should use a different acronym), and partly due to tongue-in-cheek discussions over coffee.

NADS was used with particle-swarm optimisation to design a guide system for the ILL.  The new guide system will feed two neutron spin echo instruments, a SANS instrument, a new three-axis spectrometer, a new reflectometer and fundamental physics beamlines at the ILL.

Stits Playboy. The Stits SA-3A Playboy (also called the Stitts SA-3A Playboy) is a single seat, strut-braced low-wing monoplane that was designed by Ray Stits for amateur construction. The aircraft was designed and the prototype was completed in a three-month period during 1952. The design went on to become one of the most influential in the post-war boom in aircraft homebuilding.

A side-by-side two seat version is known as the SA-3B.

Design and development
The Playboy was the third of fifteen different aircraft designs created by Stits, who migrated in the 1960s from selling plans to developing the Polyfiber line of aircraft coverings and related paint formulas.

The Playboy was designed to be constructed from either plans or from a series of partial kits. The construction is mixed  with the fuselage made from welded steel and the wings built from wood. The aircraft is fabric-covered and incorporates a sliding canopy. The aircraft is unusual in that the low wings are strut-braced.

The engine range is from  with the  Continental C85 the most commonly used.

The first in the series of Van's Aircraft designed by Richard VanGrunsven, the Van's Aircraft RV-1 was a modified Playboy and directly led to the Van's Aircraft RV-3 and the highly successful RV line of aircraft.

Operational history

Having been sold in 1955, the prototype Playboy passed through several owners' hands before being donated to the Experimental Aircraft Association.  Ray Stits was the first member of Chapter 1.  That plane is now in the EAA Airventure Museum in Oshkosh, Wisconsin.

Canada's first licensed amateur-built aircraft was a highly modified Playboy that was built by Keith S. Hopkinson. Hopkinson used the basic Playboy design and incorporated a Piper J-3 cowling, a Cessna 170 propeller spinner, de Havilland Tiger Moth wing struts, Cessna 140 conventional landing gear and Stinson 108 wheel pants.

In March 2010 there were still 41 Playboys registered in the US, six in Canada and two in the UK.

Aircraft maintenance engineer. An aircraft maintenance engineer (AME), also licensed aircraft maintenance engineer (LAME or L-AME), is a licensed person who carries out and certifies aircraft maintenance. The license is widespread internationally and is recognised by the International Civil Aviation Organization (ICAO). The American FAA recognise the qualification in foreign countries but refers to it as aviation maintenance engineer rather than "Aircraft...". Unlicensed mechanics or tradespersons are sometimes informally referred to as "unlicensed AMEs".

Countries which issue or recognize AME licenses internally include Australia, Bangladesh, Canada, India, Ireland, New Zealand, the United Kingdom and much of Asia.

The American equivalent of an AME is an aircraft maintenance technician (AMT), also known as an A&P.

Up until 1998, Type I and Type II aircraft maintenance engineer (AME) licences were distinguished. In 1998 ICAO replaced these with a single AME licence.

In 2005 the relationship between the Canadian AME and the US A&P (AMT) was further revised, through a Bilateral Aviation Safety Agreement (BASA) between the US and Canada.

E-Ship 1. E-Ship 1 is a roll-on/lift-off (RoLo) cargo ship that made its first voyage with cargo in August 2010. The ship is owned by the third-largest wind turbine manufacturer, Germany's Enercon GmbH. It is used to transport wind turbine components. The E-Ship 1 is a Flettner ship: four large rotorsails that rise from its deck are rotated via a mechanical linkage to the ship's propellers. The sails, or Flettner rotors, aid the ship's propulsion by means of the Magnus effect – the perpendicular force that is exerted on a spinning body moving through a fluid stream.

Building history

The hull of E-Ship 1 was built by German shipbuilder Lindenau Werft in Kiel. The ship's launch took place on 2 August 2008, with the delivery date estimated for the first half of 2009. In September 2008, Lindenau-Werft declared insolvency. On 25 January 2009, it was announced that E-Ship 1 would be towed to and completed by German shipyard  in Emden.

Steel construction work was completed in 2010, and the ship was docked at North Sea Works, where final construction took place with the ship in the water. In April 2010, the E-Ship 1 returned to Cassens Werft, where preparations were made for sea trials. The ship set off for a first sea trial from Emden to Bremerhaven on 6 July 2010. Three trial runs were completed until the end of July. The ship made its first voyage with cargo in August 2010, carrying nine turbines for Castledockrell Wind Farm from Emden to Dublin, Ireland.

Structure
The ship's bridge is located at the bow, and it has three decks and two port-related long-boom cranes with payload capabilities of 80 and 120 tonnes. The ship has a rear ramp, and can function as a RoLo cargo ship. It is 130 meters in length and 22.5 meters wide, with  a gross tonnage of 12,968 and a deadweight tonnage of 10,000. It is equipped with fore and aft maneuvering thrusters and has an Ice class GL E3 hull rating.

Propulsion and machinery 
The E-Ship 1 was equipped with nine Mitsubishi marine diesel engines with a total output of 3.5 MW. The ship's exhaust gas boilers are connected to a Siemens downstream steam turbine, which in turn drives four Enercon-developed Flettner rotors. These rotors, resembling four large cylinders mounted on the ship's deck, are 27 meters tall and 4 meters in diameter. The speed and direction of rotation varies up to 300RPM depending on the prevailing wind speed and direction relative to the ship.  Due to technical problems the Mitsubishi diesel generators were replaced by Caterpillar diesel generators in 2013. The new Caterpillar generators generate a total power of 6.3 MW.

Published performance information 
Performance results for the ship (including sea-keeping and wind power) were published by Enercon on 23 September 2013.
