Albatros C.IV. The Albatros C.IV, (Company post-war designation L.12). was a German military reconnaissance aircraft built in the autumn of 1915 by Albatros Flugzeugwerke. It was a single-engined biplane, and was based on the Albatros C.III, with which it shared many parts. It was eventually abandoned, in favour of the C.V.

Design and development
The C.IV shared the same fuselage, landing gear, and tail section with the C.III, but Albatros changed the design of the wings and cockpit; the pilot was located in the rear cockpit. When it was tested in 1916, the expected results of the changes did not occur, and the project was abandoned in favour of a more promising prototype, which became the Albatros C.V.

The C.IV was armed with a forward-firing LMG 08/15 machine gun, and a rear-firing, Parabellum MG14 machine gun.

Jan Ridders. Jan Ridders (Roosendaal, 1941) is a Dutch machinist, engineer and machine designer.

Ridders' designs, freely distributed, along with assistance to engineers building these motors, has brought him world reputation. He has designed and created motors which had previously been conceived only theoretically, such as a low temperature difference Stirling engine which works on heat at the tip of the hand. These motors, besides spurring engineer's imagination have also been followed up by some companies selling products based on these Ridder's design.

He is the maker of small Stirling Engines, "flame eater", steam engines and other types of small practical heat engines. Ridders gives free plans for building his motors and offers advice with his experience in various places on the web.

After years of stagnation, once shown working models and the simplicity of the design, companies began to invest in developing  concentrated light thermal solar energy solutions.

Biography 
Ridders studied physics at the Technical College of Eindhoven and continued to work for 40 years at Philips company in Roosendaal.

Upon retiring in October 2001 he began designing and building machinery, with skills which he taught himself at Philips, by closely observing their practice, while working with the mechanical department. In 2004 he received the Dutch Glacius award for his continued contribution to the Dutch National Association of Model Builders He regularly wrote in articles in "De Modelbouwer" Magazine, as well as the UK based Model Engineer magazine and the US "ModelBuilder" magazine.

Until 2007 he had been building steam engine models, but then turned to more elaborate and unusual Heat Engines, especially vacuum engines such as the flame thrower, Stirling and Rankyne engines (closed cycle Butane based steam engines). He has also been building models of unusual 2 stroke and 4 stroke motors.

Cornelius XBG-3. The Cornelius XBG-3 was an American "bomb glider", developed by the Cornelius Aircraft Corporation for the United States Army Air Forces. Using an unconventional design that included a forward-swept wing, a single prototype was ordered in 1942; however the contract was cancelled later that year before the aircraft had been constructed.

History
Early in World War II, the United States Army Air Forces initiated research into the possibility that gliders, towed by other, conventional aircraft to the area of a target, then released and guided to impact via radio control, could be a useful weapon of war. Essentially an early form of (very large) guided missile, the concept was similar to a Navy project underway at the same time, known as Glomb (from "glider-bomb"), and led to the establishment of the 'BG' series of designations, for 'Bomb Glider', in early 1942.

Among the designs considered for use as a bomb glider was an unconventional design submitted by the Cornelius Aircraft Company. Cornelius, having established a reputation for unconventional aircraft designs, proposed a design that featured a "tail-first" configuration, with canard foreplanes and a radical forward-swept wing. The USAAF considered the design interesting enough to award a contract to Cornelius for the construction of a single prototype, designated XBG-3. However the project was cancelled in late 1942, when the bomb glider concept was abandoned by the USAAF.

An enlarged, tailless, forward-swept wing glider would be built by Cornelius later in the war, acting as a "flying fuel tank" for long-range bombers, as the XFG-1.

Nanjing Dashengguan Yangtze River Bridge. The Nanjing Dashengguan Yangtze River Bridge, formerly Third Nanjing Yangtze Bridge, is the first cable-stayed bridge with steel tower stanchions located in Nanjing, China. It is the third crossing of the Yangtze River at Nanjing. The cable-stayed portion is just a part of the 4.7 kilometers of the complete bridge. Constructed in slightly more than two years at a cost of $490 million, this bridge features dual 215 meters towers.  The main span measures 648 meters. When it was completed in 2005 it was the third longest cable stayed span in the world. It still ranks among the top 20. The bridge carries the G42 Shanghai–Chengdu Expressway and the G2503 Nanjing Ring Expressway. The bridge has renamed on 20 December 2019.

Structure 
The deck superstructure is an orthotropic box girder 3.2 m deep and 37.5 wide that accommodates three lanes of traffic in each direction. Also the bridge has a center lane used in case of emergency. The deck is supported by 168 stay cables. Each cable is formed by 109 to 241 wires 7 mm in diameter and 215 m in height.

Funding 
The bridge was financed by a joint venture of Chinese public-sector and corporate entities. China's Highway Planning and Design Institute, part of the Ministry of Communications, led the design team.

Two Lines Oblique Down, Variation III. Two Lines Oblique Down, Variation III is a kinetic artwork by American artist George Rickey and located at the Indianapolis Museum of Art, near downtown Indianapolis, Indiana. The sculpture was made in 1970, and it is constructed from stainless steel.

Description
The pendulum-inspired design of Two Lines Oblique Down, Variation III is typical of Rickey’s geometric, kinetic artwork. Measured by the greatest extension of the sculpture's "arms," its size is 31' x 42' x 8'. It is constructed from at least five primary, stainless steel components which have been welded and bolted together to form linear shapes. The overall form is a Y-shaped stationary piece with two wind-powered moving pieces.

The stationary piece is square at the base and tapers up to the split of the Y.  The ends of the Y are equipped with rotating joints by which the smaller moving pieces are attached to the sculpture. Each moving piece is a triangular, tapering beam that is connected at a point approximately one fourth of its length away from the wider end of the beam. Small greased bearings keep the sculpture moving freely.

Rickey relies on random wind currents to introduce movement into his sculptures, similarly to other kinetic artists such as Alexander Calder. In contrast to the biomorphic forms of Calder's mobiles, however, Rickey's linear, oscillating forms trace paths in space that reject organic motifs in favor of geometry. The large scale of Two Lines combined with the gracefulness of the sculpture's movements emphasize the relationship between space, movement, and time.

Historical information
George Rickey made several editions of this sculpture during the years 1969 and 1970, and they can be found at various institutions across the United States.

Location History
Two Lines Oblique Down, Variation III was first displayed on the IMA's main terrace. A more protected arrangement for the artwork was desired, however, and it was moved to accommodate for extra surrounding space. The sculpture is positioned prominently next to the Efroymson Pavilion, the main entrance of the IMA, and encircled by an area of decorative landscaping.

Acquisition
The Indianapolis edition of Two Lines was accessioned by the Indianapolis Museum of Art in 1975 through The Orville A. and Elma D. Wilkinson Fund.

Datteln-Hamm Canal. The Datteln-Hamm Canal () is a canal in the German state of North Rhine-Westphalia. It links the Dortmund-Ems Canal at Datteln to the city of Hamm.

The canal is  long and has two locks, at Hamm and Werries, with a total rise of . In Hamm a water exchange facility of the Wasserverband Westdeutsche Kanäle is located that feeds the waterway with water out of the river Lippe to compensate evaporation, infiltration and operation of locks. When the water level of the river Lippe falls below a flow rate of 10 m³/second water out of the Datteln-Hamm Canal is pumped into the Lippe and the canal receives water via pumps from the Ruhr and Rhine.

History 
Canal was constructed between 1906 and 1914 for heavily industrialized area. It has given a commercial navigation. It's one of the most important canals in Germany.

Triethylgallium. Triethylgallium is the organogallium compound with the formul Ga(C2H5)3.  Also called TEGa, it is a metalorganic source of gallium for metalorganic vapour phase epitaxy (MOVPE) of compound semiconductors. It is a colorless pyrophoric liquid, typically handled with air-free techniques. It was discovered by Cornell University chemists L. M. Dennis and Winton Patnode in 1931.

Preparation and reactions
The main routes involve alkylation of gallium trichloride.  When this alkylation is effected with ethyl Grignard reagent in ether, the product is the diethyl ether adduct of triethylgallium.  The ether is not easily removed.  Thus an alternative route involves transmetalation with triethylaluminium according to this simplified equation:

Triethylgallium readily converts to the air-stable, colorless alkoxide by two routes, oxidation and alcoholysis:

The sweet odor associated with triethylgallium is due to the alkoxide.

Redistribution reactions occur with gallium trichloride:

Applications
TEGa can be a useful alternative to trimethylgallium in the metalorganic vapour phase epitaxy of compound semiconductors because films grown using TEGa have been shown to have a lower carbon impurity concentration.

Related compounds

Pratt-Read LBE. The Pratt-Read LBE-1 was a prototype glide bomb, or "Glomb", developed for the United States Navy during World War II. Although there were high hopes for the concept, the limitations of the Glomb led to the production contract for the LBE-1 being reduced, then cancelled, and only four examples of the type were ever built.

Design and development
Late in 1940, the United States Navy began seriously considering the possibility of developing gliders that would be remotely controlled to carry bombs to a target, reducing the risk to aircrew. The concept called for the glider to be towed by an ordinary carrier-based aircraft to the target area, then released, to be guided via a TV camera in the glider's nose which would transmit signals to the carrier aircraft, an operator then using radio control to steer the aircraft to its target. Considered to be feasible, the project, called "Glomb" for "Glider-Bomb", became an official program in the late spring of 1941.

Following trials using conversions of existing gliders that proved the concept viable, Pratt-Read was awarded a contract in September 1943 for the development of a purpose-built Glomb, designated by the navy as LBE-1. Intended to carry between 2,000 and 4,000 pounds (910-1,800 kg) of bombs, the LBE-1 was a fairly conventional low-wing aircraft, fitted with fixed tricycle landing gear and perforated dive brakes of the type used by dive-bombers. In addition to its radio-command guidance, the LBE-1 could be flown by a pilot for training and evaluation.

Operational history
Although the initial contract called for the production of 100 examples of the LBE-1, continued trials of the Glomb showed that the combination of the glider's low performance and technical issues with the intended television guidance system made the concept operationally unworkable; accordingly, the contract was reduced to only 35 aircraft in early 1945. In August 1945, with the end of World War II, the contract for production was cancelled entirely; only four LBE-1s would be completed, being used only for evaluation purposes.

Piper LBP. The Piper LBP was a glide bomb, or "Glomb", developed by Piper Aircraft for the United States Navy during World War II. Developed as one of three "Glomb" aircraft, the inherent limitations of the Glomb and the technology of the time, combined with difficulties encountered in testing of the prototype, led to the production contract for the LBP-1 being reduced, then cancelled, with none of the Glomb aircraft ever seeing operational service.

Design and development
During late 1940, a proposal was made to the United States Navy outlining a concept called "Glomb", for "glider bomb". The Glomb concept called for the construction of inexpensive gliders that would be remotely controlled from another aircraft to carry bombs to a target, thus reducing the risk to aircrew. Glomb was intended to be towed by an ordinary carrier-based aircraft to the area of the target, where it would be released; guidance following release would be provided via a TV camera located in the nose of the glider, which would transmit its signal to a piloted aircraft, an operator then using radio control to steer the Glomb to its target. Following consideration the Glomb concept was deemed to be potentially feasible, the project was given official status by the Bureau of Aeronautics in the April 1941.

Initial trials of Glomb involved conversions of existing gliders to remotely controlled status; these tests showed that the concept had promise and following a design competition, three companies were awarded contracts to develop operational "Glomb" aircraft. These contracts were given to Pratt-Read, Taylorcraft, and Piper Aircraft. Piper's design, designated LBP-1, was a conventional high-wing monoplane, fitted with tricycle landing gear, and intended to carry  of bombs. Although the LBP-1 was fully capable of being remotely piloted via its TV-and-radio guidance system, it retained a cockpit, allowing the aircraft to be flown by a pilot on board for training and evaluation.

Operational history
Although the initial contract awarded by the Navy called for the production of 100 LBP-1 Glombs, continued trials of the concept indicated that the glider's inherent low performance, combined with technical issues with the television guidance system, made the concept operationally unworkable. As a result, the LBP-1 production contract was reduced to only 35 aircraft in early 1945. In June of that year, the LBP-1 program was terminated, the aircraft having been determined to have dangerous characteristics when attempting landing at loaded weights.

AppStream. AppStream is an agreement between major Linux vendors (i.e. Red Hat, Canonical, SUSE, Debian, Mandriva, etc.) to create an infrastructure for application installers on Linux and sharing of metadata.

The initiative was started as early as 19-21 January, 2011.

The project describes itself as: "an initiative of cross-distro collaboration, which aims at creating an unified software metadata database, and also a centralized OCS (Open Collaboration Services) user-contributed content database, thus providing the best user experience."

With the 0.6 release, the scope of the project was expanded to include more metadata for other software components, such as fonts, codecs, input-methods and generic libraries, which will allow applications to query information about software which is available in a distribution-independent way. This enhances the quality of data displayed in software-centers, but also makes it possible for 3rd-party application installers like Listaller to find the components a new application needs to run in the distribution's package database. Additionally, the new metadata allows easier installation of prerequisites needed to build software in the first place, as well as matching upstream applications with distribution packages and matching packages across distributions, which might improve the process of exchanging patches.

AppStream is also used by packaging methods such as Snap, Flatpak, and AppImage.
