DF-224. The DF-224 is a space-qualified computer used in space missions from the 1980s.  It was built by Rockwell Autonetics.  As with many spacecraft computers, the design is very redundant, since servicing in space is at best difficult and often impossible.   The configuration had three CPUs, one active and two spares.  The main memory consisted of six memory units, each with 8K 24-bit words of plated wire memory, with up to 48K words total.  Four memory modules could be powered up at one time, resulting in a maximum of 32K words of available memory, though some applications such as the Hubble Space Telescope used fewer memory banks to allow for graceful failure modes.  There were three I/O processors, one operational and two backups.  The power supply consisted of 6 independent power converters, with overlapping coverage of the operating functions.  The processor used fixed-point arithmetic with a two's complement format.

Compared to computers that came later, the DF-224 was big and slow.  It was roughly  by  by , weighed , and had a clock speed of 1.25 MHz. 

The DF-224 on HST was augmented with a 386 co-processor on the first servicing mission (SM1). This had a clock speed of 16 MHz.

In Hubble servicing mission 3A the DF-224 (with co-processor) was replaced by the Advanced Computer using a 25 MHz Intel i486, and much more storage

The DF-224 was one of the candidate computers for the Space Shuttle, but was not selected.  It was also baselined in a version of a reusable Agena upper stage for use with the Shuttle, but this was never built.

Wag-Aero CHUBy CUBy. The Wag-Aero CHUBy CUBy is a high-wing four-seat homebuilt cabin monoplane of tube-and-fabric construction, it is a modern representation of the  Piper PA-14 taildragger with elements from other Piper family members. The plane is currently marketed as the Wag-Aero Sportsman 2+2 by Wag-Aero in kit form.

Design and development
The CHUBy CUBy was the third homebuilt replica of a Piper product from parts supplier Wag-Aero. The PA-14 line was a popular aircraft for Alaska floatplane operations and the CHUBy CUBy was put to market to allow new examples to be built. The aircraft has an optional large opening to the baggage compartment similar to the Piper HE-1 ambulance style door.

The CHUBy CUBy closely resembles the Piper PA-14, but has several modifications. The recommended engine is the Lycoming O-320-E2D of  or Lycoming O-290 of  hung on a custom-designed swing-out engine mount. The CHUBy CUBy has swing-up doors on both sides of the cabin and two wing-mounted fuel tanks with a small header tank. The fuselage is welded from 4130 steel tubing rather than 1020 grade steel used in the original. The wings include spoilers to keep the aircraft on the ground and avoid floating.

Wag-Aero company president Dick Wagner flew the CHUBy CUBy for the first time on May 8, 1982.

Remarul 16 Februarie. Remarul 16 Februarie SA based in Cluj-Napoca is a railway rolling stock engineering company with services including repair, maintenance and modernisation.

History
The company's history dates back to the Austro-Hungarian period - 1870, with the creation of a railway workshop to serve the Cluj–Oradea line (Grosswardein-Klausenburg railway.); the works repaired wagons and locomotives.

The initial wooden works building was constructed in 1870, this was replaced by substantial rolling stock works on the current site in 1874 - a locomotive repair shed of 1653m2, a wagon repair shed of 3200m2 and a mechanical workshop of 2190m2. With additional offices, warehouses the site had an area of nearly 36,000m2.

In 1882 the works employed 200, by the 1890 the number had risen to nearly 500. In 1918 (as a result of the Union of Transylvania with Romania) the works became the Atelierele CFR Cluj, and from 1929 to 1940 was named Inspecţia Atelierelor Principale CFR Cluj. The works was expanded and rebuilt during the 1920s and 30s with older buildings demolished - by 1938 the expanded works employed 1675.

In 1971 the works began to repair diesel-hydraulic locomotives whilst still maintaining steam locomotives. In 1990 the works was named Remarul 16 Februarie S.A., and was privatised in 2000. Much of the bankrupt metalworking company Metalurgica SA of Aiud,  Transylvania, Romania (casting including centrifugal casting, hot forging, mechanical engineering) was acquired in 2006.

In 2009 the company entered into partnership with Caterpillar Inc., acting as a centre for rail vehicle re-motorisation in the region. In 2009 the Company's major shareholders were Transferoviar Group SA (32.96%) and Monica Băiculescu (32%) and  Nova Cominvest (6.54%).

In November 2010 the company acquired a license for the production of AGC trainsets from Bombardier Transportation - the license is exclusive for the trains produced for Romania, Bulgaria, Greece, Croatia, Bosnia and Serbia. The company is expected to invest €20 million and increase the workforce to 1000 for the production of the AGC.

Products and services
The company specialises in construction and repair of railway rolling stock, the company also manufactures parts for hydraulic diesel locomotives. Much of the company's income is based on modernisation of rolling stock. The company's  suppliers include Inda Craiova, Softronic Craiova, Caterpillar Inc, Integral Consulting R & D Bucurest, Voith, and Knorr Bremse.

As of 2012 in addition to multiple unit and locomotive repair and modernisations the plant still repairs steam locomotives.

Trimethylborane. Trimethylborane (TMB) is a toxic, pyrophoric gas with the formula B(CH3)3 (which can also be written as Me3B, with Me representing methyl).

Properties
As a liquid it is colourless. The strongest line in the infrared spectrum is at 1330 cm−1 followed by lines at 3010 cm−1 and 1185 cm−1.

Its melting point is −161.5 °C, and its boiling point is −20.2 °C.

Vapour pressure is given by , where T is temperature in kelvins.  Molecular weight is 55.914. The heat of vapourisation is 25.6 kJ/mol.

Preparation
Trimethylborane was first described in 1862 by Edward Frankland, who also mentioned its adduct with ammonia. Due to its dangerous nature the compound was no longer studied until 1921, when Alfred Stock and Friedrich Zeidler took advantage of the reaction between boron trichloride gas and dimethylzinc. Although the substance can be prepared using Grignard reagents the output is contaminated by unwanted products from the solvent.  Trimethylborane can be made on a small scale with a 98% yield by reacting trimethylaluminium in hexane with boron tribromide in dibutyl ether as a solvent.  Yet other methods are reacting tributyl borate with  trimethylaluminium chloride, or potassium tetrafluoroborate with trimethylaluminium, or adding boron trifluoride in ether to methyl magnesium iodide.

Reactions
Trimethylborane spontaneously ignites in air if the concentration is high enough.  It burns with a green flame producing soot. Slower oxidation with oxygen in a solvent or in the gas phase can produce dimethyltrioxadiboralane, which contains a ring of two boron and three oxygen atoms.  However the major product is dimethylborylmethylperoxide, which rapidly decomposes to dimethoxymethylborane.

Trimethylborane is a strong Lewis acid. B(CH3)3 can form an adduct with ammonia: (NH3):B(CH3)3. as well as other Lewis bases.  The Lewis acid properties of B(CH3)3 have been analyzed by the ECW model yielding  EA= 2.90 and CA= 3.60. When trimethylborane forms an adduct with trimethylamine, steric repulsion between the methyl groups on the B and N results. The ECW model can provide a measure of this steric effect.

Trimethylborane reacts with water and chlorine at room temperature. It also reacts with grease but not with teflon or glass.  

Trimethylborane reacts with diborane to disproportionate to form methyldiborane and dimethyldiborane: (CH3)BH2.BH3 and (CH3)2BH.BH3.

It reacts as a gas with trimethylphosphine to form a solid Lewis salt with a heat of formation of −41 kcal per mol.  This adduct has a heat of sublimation of −24.6 kcal/mol. No reaction occurs with trimethylarsine or trimethylstibine.

Methyl lithium reacting with the Trimethylborane produces a tetramethylborate salt: LiB(CH3)4. The tetramethylborate ion has a negative charge and is isoelectronic with neopentane, tetramethylsilane, and the tetramethylammonium cation.

Use
Trimethylborane has been used as a neutron counter.  For this use it has to be very pure.  It is also used in chemical vapour deposition where boron and carbon need to be deposited together.

Temperature–entropy diagram. In thermodynamics, a temperature–entropy (T–s) diagram is a thermodynamic diagram used to visualize changes to temperature () and specific entropy () during a thermodynamic process or cycle as the graph of a curve. It is a useful and common tool, particularly because it helps to visualize the heat transfer during a process. For reversible (ideal) processes, the area under the T–s curve of a process is the heat transferred to the system during that process.

Working fluids are often categorized on the basis of the shape of their T–s diagram.

An isentropic process is depicted as a vertical line on a T–s diagram, whereas an isothermal process is a horizontal line.

Davey Hall. Davey Hall (born 1951) is a British trade unionist.

Hall worked as an engineer at the Swan Hunter shipbuilding yard.  He joined the Amalgamated Engineering Union (AEU), and became a shop steward. In 1988, he became the union's Tyne district secretary.

The AEU became part of the Amalgamated Engineering and Electrical Union (AEEU), and Hall served as its president from 1995 to 1998; although he was a supporter of Tony Blair, he was described as the union's most left-wing president since Hugh Scanlon. The AEEU then merged into Amicus, which in turn became part of Unite, with Hall serving as its regional secretary for the North East, Yorkshire and Humberside. He took early retirement in 2011, but later began working for the Prospect trade union, in a similar post.

Ker-Plop. "Ker-Plop" is a science fiction novella by Ted Reynolds, which first appeared in Isaac Asimov's Science Fiction Magazine, January 1979.

Synopsis
Cotter Oren is a checker-pilot, an elite group tasked to 'meet and greet' travellers from deep space who arrive in the automatic net around the planet Randar. His job is to locate and remove the arriving ship's 'sealsafe', thus nullifying any possible hostile intent, and sending the passengers and crew to the surface for psychotherapy, which most require after their long journeys. But during one shift, he is ordered by Flynn Rose, his controller, to check a ship which is supposedly of five thousand kilometers radius - unimaginably large, and therefore considered to be potentially hostile.

On returning from this mission, he is debriefed under hypnosis by an official known as The Examiner. He tries to recall the events of his journey into the ship...

Oren approaches cautiously in his miniaturised checkership, lands and is able to enter via an airlock. A still-functioning security system directs him to remove and deposit his checker-suit and weapons (which render the user invulnerable to almost any attack) and he continues on his way to the ship's centre of gravity, where the sealsafe must be located.

Cotter meets various inhabitants, none of whom exhibit any curiosity and are apparently unaware that their planet is really a spaceship. He sees no evidence of any government or officials in charge. He realises that the ship is populated in three dimensions.

Reaching the ship's core, he meets a man, who identifies himself only as Basho and describes himself as a janitor. Basho explains that the planet, known as Golgaronok, has now returned from the Magellanic Clouds - a journey that started 300,000 years ago. It is a remnant of a former galactic confederation known as the Amalgamate. Basho forces Oren to mentally calculate the living space and possible population of the ship; Oren, with increasing panic, realises that the population could be many times greater than that of the galactic confederation of which Randar is a part.

Basho persuades Oren that, rather than Randar accepting the arrival of Golgaronok, the latter should in fact absorb Randar. Oren then realises that he has been hypnotised by Basho and that Basho is pumping him for information. The Examiner is actually Basho and he is still within the planet-ship.

Ventura Corporate Towers. The Ventura Corporate Towers is an office building in the Centro neighbourhood of Rio de Janeiro, Brazil, fronting the avenue between Chile and Lavradio, the street in front of the Rio de Janeiro Cathedral. It was built by Camargo Correa in partnership with Tishman Speyer, who together invested 500,000,000 reais. Designed by Kohn Pedersen Fox Associates, the building has achieved LEED certification, by presenting streamlined and intelligent use of water. Moreover, the special glass provides natural lighting and is not so warm inside the building, reducing expenses with chilled air and light. Together with the Ventura Corporate Tower II, the venture will strengthen the corridor's commercial avenues in Chile, formed by the BNDES, Petrobras, and Caixa Economica Federal. The tower is 140 meters tall, with 36 floors and a heliport.

KiHa 120. The  is a single-car diesel multiple unit (DMU) train type operated by West Japan Railway Company (JR-West) on its rural lines in Japan. Based on Niigata Tekkō's "NDC" lightweight diesel car design intended for third sector operators (such as Matsuura Railway, Takachiho Railway, and Kumagawa Railway), a total of 89 cars were built, with the class divided into three sub-classes: KiHa 120-0, KiHa 120-200, and KiHa 120-300.

Variants

KiHa 120-200
Eight first-batch cars were built in 1992. These had painted steel bodies, two-pane windows, transverse and longitudinal seating, and no toilets. All cars were later modified with the addition of toilets.

KiHa 120-0
22 second-batch cars were built in 1993, including three cars built at JR-West's Gotō Works. These had uprated engines, stainless steel bodies, single-pane windows, longitudinal seating, and no toilets. All cars were later modified with the addition of toilets.

KiHa 120-300
59 third-batch cars were built between 1994 and 1996, including 19 cars built at JR-West's Gotō Works. These were similar in design to the KiHa 120-0 subclass, but were built with some transverse seating. Although not initially built with toilets, all cars were modified with the addition of toilets from 2005.
