Ball Jacks. is a 1993 action video game developed and published by Namco for the Sega Mega Drive in Japan and Europe.

Gameplay

Ball Jacks is a futuristic action game that involves an ultra-competitive sporting event. Two robot crabs are controlled by men who play the game merely to become wealthy and famous. There is a conveyor belt behind them that spews metal balls at them. The goal is to capture balls that belong to the opponent and keep them from him until time runs out. Balls can also be knocked out from the mechanical hands of the opponent. All damaged crabs must return to the pit area for a quick maintenance and repair session.

There are several modes: a world championship against increasingly tougher opponents, a multiplayer versus mode, a training mode, and a time trial where the time limit is the only foe.

Reception

The game was poorly received, with Andy Dyer criticising the graphics, sound, gameplay and size.

Godofredo García. Godofredo García (born in Lima, Peru, November 8, 1888 - July 16, 1970) was a Peruvian mathematician and engineer. He was the author of more than 80 publications covering mathematics, physics, astronomy, astrophysics, and engineering.

Background
He studied at the Colegio de Lima, under Pedro A. Labarthe. In 1906 he entered the Faculty of Sciences of the National University of San Marcos, where he received a bachelor's degree (1909) and later his doctorate degree in Mathematical Sciences (1912), with his thesis on "Singular points of flat curves" and "Resistance of Columns of reinforced concrete", respectively. Simultaneously, he studied at the School of Engineers of Peru, now called the National University of Engineering (1908-1910), graduating from Civil engineer in 1911.

From 1912, he taught at the Chorrillos Military School, where he was in charge of the courses of Flat, Descriptive and Analytical Geometry, Infinitesimal Calculus, Rational Mechanics and Exterior Ballistics. He was also professor of Rational Mechanics in the Faculty of Sciences of the University of San Marcos beginning in 1919 and later served as dean (1928-1940). He became Rector (1941-1943). He was also a professor at the School of Engineers corresponding with Albert Einstein.

In the 1920s he worked with the Polish mathematician Alfred Rosenblatt in San Marcos. In 1938, together with Rosenblatt and other San Marcos mathematicians, he founded the National Academy of Exact, Physical and Natural Sciences of Peru, an institution that he presided over from 1960 until he died in 1970. He also directed the publication Actas de la Academia".

García was elected to the American Philosophical Society in 1943. He was awarded the national prize for scientific research, in recognition of his contributions in the field of mathematical sciences and his "Exact equations and exact solutions to the movement and stresses of viscous fluids" (1948).

He organized conferences in Lima with the participation of Tullio Levi-Civita, Arthur Compton and Garret Birkhoff, among others. In each conference Godofredo García presented a review of the work of these scientists.

He married Alicia Rendón (Ecuadorian) and fathered four children.

Golden Gate Mosquito. The Golden Gate Mosquito is an American ultralight aircraft that was produced by Golden Gate Aviation. The aircraft was supplied as a kit for amateur construction.

Design and development
A copy of the popular Phantom X1, the Mosquito was designed to comply with the US FAR 103 Ultralight Vehicles rules, including the category's maximum empty weight of . The aircraft has a standard empty weight of . It features a strut-braced or optionally cable-braced high-wing, a single-seat, open cockpit, tricycle landing gear and a single engine in tractor configuration.

The aircraft is made from aluminum tubing, with the flying surfaces covered in Dacron sailcloth. Its  span wing was available in a strut-braced or cable-braced configuration, the cable bracing giving better negative g performance. On the cable-braced version the ground wires are supported by an inverted "V" kingpost. The aircraft is rated for load limits of +10/-6 g. The pilot is accommodated on a seat within a semi-enclosed fiberglass pod that includes a windshield. The standard engine is a Kawasaki 440 snowmobile engine of , mounted at the front of the main fuselage keel tube, above the pilot. The cruciform tail is mounted at the aft end of the same keel tube.

Miguel Lebrija. Miguel Lebrija Urtetegui (20 November 1887 — 15 December 1913) was a Mexican aviation pioneer. In 1909, built and flew his own glider. He was active in the service of the Mexican government during the Mexican Revolution, and his service would help to establish the Mexican Air Force.

Flying over Metropolitan Cathedral in Mexico City, he proved that planes can work at an altitude over 2,000 meters.

Career
The first of Miguel Lebrija's known experiments with aviation came in April 1908, when he used an automobile to tow a biplane, coaxing it into flight.
In 1910 Miguel Lebrija acquired the first plane in Mexico, a plane from Blériot Aéronautique owned by El Buen Tono, who were selling it because it could not fly. He fixed its engine and became the second person in Mexico to ever fly on 14 May 1910, flying for five minutes. In doing so, he also proved that an airplane could fly at the altitude of Mexico City, which is approximately 2,200 meters. He also acquired a Deperdussin.

In February 1913 Lebrija was refused a bombing run over Mexico City from Victoriano Huerta. Instead, he dropped test bombs at Llanos de Balbuena, the first airport in Mexico, in April 1913. Lebrija was promoted to the rank of 'Honorary Major' in the air force, then the Army's Auxiliary Aerial Militia Squadron (), and was sent off to New York and later France to purchase 20 airplanes and two dirigibles for the fledgling air force. Previously, similar missions had been denied to exist by Luis Perez Figueroa in July 1910. Regardless, Lebrija died in December in Paris after a surgery.

Lebrija was of the opinion that there would be thousands of Mexican airmen fighting in the Mexican air fleet in only a few years.

Phenyl acetate. Phenyl acetate is the ester of phenol and acetic acid. It can be produced by reacting phenol with acetic anhydride or acetyl chloride.

Phenyl acetate can be separated into phenol and an acetate salt, via saponification: heating the phenyl acetate with a strong base, such as sodium hydroxide, will produce phenol and an acetate salt (sodium acetate, if sodium hydroxide were used).

Closed-cycle gas turbine. A closed-cycle gas turbine is a turbine that uses a gas (e.g. air, nitrogen, helium, argon, etc.) for the working fluid as part of a closed thermodynamic system. Heat is supplied from an external source. Such recirculating turbines follow the Brayton cycle.

Background
The initial patent for a closed-cycle gas turbine (CCGT) was issued in 1935 and they were first used commercially in 1939. Seven CCGT units were built in Switzerland and Germany by 1978. Historically, CCGTs found most use as external combustion engines "with fuels such as bituminous coal, brown coal and blast furnace gas" but were superseded by open cycle gas turbines using cleaner-burning fuels (e.g. "gas or light oil"), especially in highly efficient combined cycle systems. Air-based CCGT systems have demonstrated very high availability and reliability. The most notable helium-based system thus far was Oberhausen 2, a 50 megawatt cogeneration plant that operated from 1975 to 1987 in Germany. Compared to Europe where the technology was originally developed, CCGT is not well known in the US.

Nuclear power
Gas-cooled reactors powering helium-based closed-cycle gas turbines were suggested in 1945. The experimental ML-1 nuclear reactor in the early-1960s used a nitrogen-based CCGT operating at 0.9 MPa. The cancelled pebble bed modular reactor was intended to be coupled with a helium CCGT. Future nuclear (Generation IV reactors) may employ CCGT for power generation, e.g. Flibe Energy intends to produce a liquid fluoride thorium reactor coupled with a CCGT.

Development
Closed-cycle gas turbines hold promise for use with future high temperature solar power and fusion power generation.

They have also been proposed as a technology for use in long-term space exploration.

Supercritical carbon dioxide closed-cycle gas turbines are under development; "The main advantage of the supercritical CO2 cycle is comparable efficiency with the helium Brayton cycle at significantly lower temperature" (550 °C vs. 850 °C), but with the disadvantage of higher pressure (20 MPa vs. 8 MPa). Sandia National Laboratories had a goal of developing a 10 MWe supercritical CO2 demonstration CCGT by 2019.

Applied Maths. Applied Maths NV, a bioMérieux company headquartered in Sint-Martens-Latem, Belgium, is a bioinformatics company developing software for the biosciences.

History

Applied Maths was founded in 1992 and gained worldwide recognition with the software GelCompar, used as a standard tool for the normalization and comparative analysis of electrophoresis patterns (PFGE, AFLP, RAPD, REP-PCR and variants, etc.).

GelCompar II was released in 1998 to deal with the ever growing amounts of information following the success and expansion of electrophoresis and other fingerprinting techniques in various application fields in microbiology, virology and mycology. Following the introduction of the concepts of polyphasic taxonomy  and the growing need to combine genotypic, phenotypic, electrophoresis and sequence information, Applied Maths released in 1996 the software package BIONUMERICS which still today is a platform for the management, storage and (statistical) analysis of all types of biological data. BIONUMERICS and GelCompar II are used by several networks around the globe, such as PulseNet and CaliciNet, to share and identify strain information.

In January 2016, Applied Maths was acquired by bioMérieux. In October 2021, the company announced the phase out of its flagship software BIONUMERICS by the end 2024. Applied Maths merged with bioMérieux in June 2023.

Products

BIONUMERICS: BIONUMERICS is a commercial suite of 4 configurations used for the analysis of all major applications in (microbial) bioinformatics: 1D electrophoresis gels, chromatographic and spectrometric profiles, phenotype characters, microarrays, nucleic acid sequences, whole genome sequences etc.

Åmodt bro. Aamodt bru is a suspension bridge located Oslo, Norway.   It is a pedestrian bridge over the Aker River in the Oslo district of  Grünerløkka.

History 
Aamodt bru was originally built over the Drammen River  in Buskerud near the mouth of the Simoa river at Åmot in Modum.   The bridge was built during 1851–1852 of cast iron chains made with cast iron from the Nes Jernverk.   The bridge was one of the earliest chain hangers in Norway.

Aamodt bru was later replaced by a new bridge due to poor condition and was given to Oslo municipality. During 1952 Aamodt bru was dismantled and moved piece by piece to a new site on the Aker River. It was intended to serve as an entrance to the Technical Museum which was planned to be built at the Aker River. However, the museum was later built elsewhere. Today the bridge is only used as a bicycle and pedestrian bridge.

Inscription 

The bridge has an inscription which serves as a warning in . An English language translation of this is: "100 men I can bear, but [I will] fail during a rhythmic march".

Track gauge in Switzerland. Switzerland has an extensive network of  metre gauge railways, many of which interchange traffic (most prominent is the Rhaetian Railway).  They are concentrated in the more heavily mountainous areas. The Jungfrau Railway terminates at the highest station in Europe. Dual gauge (combined metre- and standard gauge trackway) also exists in many areas. Also, nearly all street tramways in Switzerland have always been meter gauge.

Gauge changing trains 
Since December 2022, / gauge changing trains have started operating between Lake Geneva and Interlaken. Zweisimmen is the location of the gauge change. While the carriage gauge is changed, the locomotives do not change gauge and they have to be interchanged.

3 ft gauge railways. Three foot gauge railways have a track gauge of  or 1 yard. This gauge is a narrow gauge and is generally found throughout North, Central, and South America. In Ireland, many secondary and industrial lines were built to  gauge, and it is the dominant gauge on the Isle of Man, where it is known as the Manx Standard Gauge. Modern  gauge railways are most commonly found in isolated mountainous areas, on small islands, or in large-scale amusement parks and theme parks (see table below). This gauge is also popular in model railroading (particularly in G scale), and model prototypes of these railways have been made by several model train brands around the world, such as Accucraft Trains (US), Aristo-Craft Trains (US), Bachmann Industries (Hong Kong), Delton Locomotive Works (US), LGB (Germany), and PIKO (Germany).

Blue Vixen. 

Blue Vixen was a British airborne radar designed and built for the Royal Navy by Ferranti Defence Systems (later, GEC-Marconi), Edinburgh, Scotland. It was the primary radar of later models of the British Aerospace Sea Harrier, replacing the Ferranti Blue Fox used on earlier models of the Harrier.

Design and development
Blue Vixen was a lightweight (145 kg) multimode, coherent, pulse-Doppler I band airborne radar, developed from the previous Ferranti Blue Fox radar, and designed for use on the British Aerospace Sea Harrier FA2. It was a multimode radar for airborne interception and air-to-surface strike roles over water and land, with look-down/shoot-down and look-up modes.  Designed from the start to have full AIM-120 AMRAAM compatibility, it was also compatible with Sea Eagle and AIM-9 Sidewinder missiles.

Development aircraft used

Two British Aerospace 125 aircraft were used for the flight trial's program. The first (XW930 serial number 25009) was a Series 1 aircraft which had previously been used by the CAFU (Civil Aviation Flying Unit) before it was absorbed into the Royal Aircraft Establishment. It was equipped with a modified nose and carried out the initial development work. This was joined by the dedicated trials aircraft (a series 600 serial number 256059 registered ZF130), fitted with a replica of the Sea Harrier cockpit at the co-pilot's station as well as a Sidewinder acquisition round on a pylon beneath the starboard wing.

Elitar-202. The Elitar-202 or Elitar (Samara VVV-Avia) 202 is a conventionally laid out, single engine ultralight aircraft which seats two in side-by-side configuration. Designed in Russia, production of the Type 202 began in 2003.

Design and development

Like the Elitar Sigma, the Elitar-202 is manufactured at Samara by VVV-Avia. It is a low wing monoplane constructed largely of composites, with foam filled GRP surfaces and GRP/carbon fibre wing spars.  The wings are fitted with flaps and in plan have rounded leading edges near the upturned tips.  The leading edge of the fin is strongly swept; the rudder is less swept and has a cut-away at its base for elevator movement.  There is a small ventral fin.

The side-by-side seating is enclosed by a rear hinged, largely transparent canopy, with another transparency behind on each side of the rearward tapering fuselage. The 202 is powered by a 73.5 kW (98.6 hp) Rotax 912ULS flat four engine driving a three blade propeller.  It has a fixed, tricycle undercarriage, with faired mainwheels mounted on cantilever spring legs and a trailing link nosewheel. A MVEN K-700-00 ballistic recovery parachute is an option.

Operational history
The 202 was first seen in public in 2003 at MAKS '03 in Moscow. Ten were reported built and twelve more on order at this time. It was predicted that certification would be completed by November 2003 but in 2009 this remained unconfirmed.
