TouchLight. TouchLight is an imaging touch screen and 3D display for gesture-based interaction. It was developed by Microsoft Research employee Andrew D. Wilson and made known to the public in late 2005. The technology was licensed to Eon Reality in July 2006.

Abilities
The TouchLight can both record and project simultaneously, and due to its 3D capabilities can be used almost as a mirror.  This same principle  could be applied to link two TouchLights together allowing two people anywhere in the world to communicate with each other as if they were sitting on opposite sides of the same desk.  It can capture a high definition image of anything placed up against the screen. This image is then displayed in 2D.  The user of the TouchLight can manipulate the size, position and orientation of the image by performing the corresponding action with his or her hands.  The screen has a microphone built in that can detect vibration, thus allowing the user to change setting simply by tapping the screen.

Cost
In 2006, the high end product cost upwards of $60,000.

Dnepr M-72. The M-72 was a motorcycle built by the Soviet Union. Conceived as a replacement for the two heavy motorcycles used by the Red Army, the TIZ-AM-600 and PMZ-A-750, both of which had performed unsatisfactorily during the Winter War against Finland and were considered outdated designs. The replacement chosen was the BMW R71, which had been rejected by the German Wehrmacht as a replacement for the R12. As a result of the Molotov–Ribbentrop Pact, the necessary legal, political and economic procedures were in place for BMW to provide the design, tooling and training for the manufacture of the motorcycle and military sidecar.

History
The M-72 was intended to be built at three factories located in Moscow, Leningrad and Kharkiv, with ancillary items coming from several other factories. Only the MMZ factory in Moscow produced any complete motorcycles prior to the German invasion in 1941 and commencement of the Eastern Front.

Then, the Moscow factory was moved east to the town of Irbit in Western Siberia, becoming the Irbit Motorcycle Factory (IMZ). The Kharkiv and Leningrad factories were relocated to Gorky on the outskirts of the GAZ plant, becoming the Gorky Motorcycle Plant (GMZ). During the war, motorcycles were produced at both factories. However, all sidecars for both the M-72 and Lend-Lease bikes were produced at Gorky only.

In 1952, 500 M-72 engines were shipped from the IMZ to the KMZ factory in Kyiv to produce their first batch of M-72s. KMZ produced the M-72 until 1956. A closely related model, the M-72N, was produced later.

In 1957, the Soviets sold the M-72 production line to the People's Republic of China. The IMZ plant supplied M-72s to China up to the transfer of the production line in 1957 and continued to supply parts to China until 1960. Production continued in China through the mid-1980s. The M-72's current descendant is the CJ750 of the Chang Jiang series.

Design

M-72 motorcycles were predominantly produced with a sidecar attached, although some solos made appearances for escort duties and the like.

M-72 were produced at IMZ in Irbit from 1942 until 1955. A subsequent model, the M-72M was produced from 1955 until 1960.

Haringvlietdam. The Haringvlietdam, incorporating the Haringvliet sluices, are hydraulic engineering structures which closed off the estuary of the Haringvliet, Netherlands, as part of the Delta Works. The structure consists of 17 sluices, several kilometres of dam and a shipping lock, and formed the sixth project of the Delta Works.

The northernmost of the Delta Works, it was supposed to be finished by 1968 as the first part of the project. Building started in 1957 and was finished in 1971. Instead of damming the estuary it was decided to  build sluices in order to be able to let in salt water to prevent freezing of the rivers Meuse and Rhine and to drain these rivers in case of flood. 

The height of the dam crest is 18.5m above Normaal Amsterdams Peil (NAP), and 17.3m above the water level in the Haringvliet. The width between piers is 56.5 metres, and the depth of the sill of the gates was partly determined by the need for ice breakers to pass through them at low tide, being fixed at 5.5 metres below NAP.

The sluice complex has 17 openings and an effective total aperture of about 6,000 square metres at half tide. The sluices have two doors each, of which the door on the sea side is the lowest. This was undertaken to mitigate the effect of waves on the doors. On the seaward side of the sluice complex, there is a 7m deep step to induce wave breaking against a concrete wall, thus reducing the strain on the gates by around 50%.

The subsoil consists of clay and soft sandy layers to depths ranging from 20 to 30 metres below NAP. The sluice structures are founded on pile foundations.

In 2011, Rijkswaterstaat implemented a ‘Kierbesluit’ policy, which directed that the Haringvliet sluices be opened slightly when the Haringvliet water level is lower than the sea water level, allowing limited saltwater intrusion and the migration of fish into the Haringvliet. The policy was implemented in order to improve the ecological situation in the Meuse and Rhine. The change has also resulted in a minor return of the tides in areas like Tiengemeten and the Biesbosch, both of which are important nature reserves.

OScar. OScar was the first attempt to design an open-source car as open source hardware. The aim of the project is mainly to produce blueprints, using essentially open-source CAD. The project commenced in 1999, founded by Markus Merz with Tiago do Vale as design director, and launched its 0.2 release in 2006, but no further progress has been made.

Goal and challenges 

The goal of the project is not to produce a sophisticated car, but rather a simple and functional basic one, which answer people's basic transportation needs. A long-term goal is also to introduce standardization in parts manufacturing (very much in the open-source way) to use economies of scale. This is a radical change from the car industry's current practices and business model, where every manufacturer has their own standards. This monopoly on brand-specific parts often constitutes an important part of the manufacturers' revenues.

Among the challenges this car will have to overcome, before reaching the manufacturing phase, are to conduct crash tests and also to abide by very strict security legislation and pollution norms in the car industry. This has led to proposals for low-carbon alternative propulsion OScars (hybrid, hydrogen vehicle, and electric versions).

Soundcraft. Soundcraft is a British designer and importer (formerly a manufacturer) of mixing consoles and other professional audio equipment. It is a subsidiary of Harman International Industries, which is owned by South Korean company Samsung Electronics.  It was founded by sound engineer Phil Dudderidge and electronics designer Graham Blyth in 1973.

History
Soundcraft first made its mark by manufacturing the Series 1, the first mixing console built into a flight-case. It was available with 12 or 16 input channels and 4 outputs—main stereo, plus a post-fader ‘echo’ send and pre-fader foldback.  Each channel had four-band fixed-frequency EQ.  The Series 1 also included a multi-pin connector that integrated with a multi-channel microphone snake to route signals from and to the stage from a mix position in the audience.

The Series 1S was introduced in 1975 as an upgraded Series 1.  The Series 1S introduced the classic Soundcraft four-band EQ with two sweepable mid-range sections. In addition to The Series 1S added a second foldback send and was available in a 20 channel version.

In 1975, Soundcraft introduced the Series 2 console as a live and recording console. The Series 2 began to build Soundcraft's reputation for quality desks with the classic British sound.  The Series 2 launched as a four-bus console, and was later available in an eight-bus version.  It was initially offered in 12 and 16 channel versions, and a 24 channel version was later added.  The design used a semi-modular approach with individual channels in separate modules. The master section was made up of echo return, group output, cue master and monitoring modules. The input channels were available in fixed-frequency EQ standard channel and swept EQ versions.  The swept EQ version also allowed switching between microphone input and line input, which was typically attached to a multi-track recorder output.  All channels provided stereo pan as well as four cue send buses that could be configured as pre- or post-fader and allowed individual monitoring via a pre-fade listen (PFL) function. Each channel could be routed directly to the left–right mix bus or to odd/even pairs of sub-mix buses.

Baffle spray scrubber. Baffle spray scrubbers are a technology for air pollution control.  They are very similar to spray towers in design and operation. However, in addition to using the energy provided by the spray nozzles, baffles are added to allow the gas stream to atomize some liquid as it passes over them. 

A simple baffle scrubber system is shown in Figure 1. Liquid sprays capture pollutants and also remove collected particles from the baffles. Adding baffles slightly increases the pressure drop of the system.

This type of technology is a part of the group of air pollution controls collectively referred to as wet scrubbers.

A number of wet-scrubber designs use energy from both the gas stream and liquid stream to collect pollutants. Many of these combination devices are available commercially. 

A seemingly unending number of scrubber designs have been developed by changing system geometry and incorporating vanes, nozzles, and baffles.

Particle collection

These devices are used much the same as spray towers - to preclean or remove particles larger than 10 μm in diameter. However, they will tend to plug or corrode if particle concentration of the exhaust gas stream is high.

Gas collection

Even though these devices are not specifically used for gas collection, they are capable of a small amount of gas absorption because of their large wetted surface.

Summary

These devices are most commonly used as precleaners to remove large particles (>10 μm in diameter). The pressure drops across baffle scrubbers are usually low, but so are the collection efficiencies. Maintenance problems are minimal. The main problem is the buildup of solids on the baffles.Table 1 summarizes the operating characteristics of baffle spray scrubbers.

Coedty Reservoir. Coedty Reservoir is a reservoir in Snowdonia, North Wales.  It is fed by the waters of Afon Porth-llwyd which flows from Llyn Eigiau. The reservoir lies at a height of , and measures some  in size. It contains brown trout.

The original dam was built in 1924 to provide hydro-electric power to the aluminium smelting works in Dolgarrog. In 1925, the Eigiau dam broke, and the flood of water from that  also burst Coedty dam. The resultant flood caused the loss of 16 lives in Dolgarrog.

The dam was rebuilt in 1926, and altered again in 1956.

Water from the reservoir, which has a catchment area of around 27 square kilometres, is carried via a 3 km large metal pipe down to the hydro-electric power-station in Dolgarrog.

Coedty dam is a balance tip dam; water flows from it automatically when it reaches high levels.  This excess water flows into a spectacular gorge used by outdoor pursuit groups. Gorge walking here, however, can be dangerous because of the sudden releases of water from the reservoir which can occur.

The eastern side of the lake is skirted by the trackbed of the former Eigiau Tramway, created to aid the construction and maintenance of Llyn Eigiau dam.  Nearby the Cowlyd Tramway branched off, built to aid the construction of the dam at Llyn Cowlyd.

Hani Azer. Hani Azer (, ; born 1948) is an Egyptian-German civil engineer. He was born in Tanta, Egypt to a Coptic family and moved to Cairo for high school and university. In 1973, after earning a BSc(Engg) degree from the Faculty of Engineering, Ain Shams University, he moved to Germany to study for his post-graduate diploma in civil engineering in Bochum.

Azer headed the construction of the tunnel beneath Berlin's Tiergarten in 1994. Subsequently, he became the chief engineer of the Berlin Hauptbahnhof, Germany's fourth-largest train station. The station is a modernistic structure with a roof built almost entirely of glass blocks. The project cost $700 million. Berliners voted Azer 13th in the top 50 Berliners of the year in 2006.

Azer was honored by the German Chancellor Angela Merkel on 26 May 2006 at the inauguration of the Berlin Hauptbahnhof. He was also later honored by Egyptian president Hosni Mubarak. On 1 October 2006, Azer received one of Berlin's most respected distinctions, the Verdienstorden des Landes Berlin (Merit of the State of Berlin), for outstanding service to the state. Azer is also considered one of the top tunneling and bridge engineers at the global level today.

Enterprise encryption gateway. An enterprise encryption gateway (EEG) is a layer 2 encryption device, similar to VPN, that allows for strong authentication and encryption for data across a wireless medium. Unlike a residential gateway, an enterprise gateway typically has both an LAN and WLAN interface, where the EEG acts a bridge between the two. The client devices have client-side authentication/encryption software, and the EEGs are the encryption termination point in the network.  Benefits of these devices include offloading the encryption duties from the access points. Autonomous access points are placed downstream from the EEGs and may act as an 802.1X authenticator.

Rio Adio. Rio Adio () is a 1989 Bulgarian social drama film about the life of an architect, directed by Ivan Andonov. The film is centered on important social themes of self-morality and moral compromise. The film stars Filip Trifonov.

Plot
Stoev (Trifonov) is a talented lead architect whose team wins an international competition for a facility to be built in Rio de Janeiro. Per the terms of the agreement, two members of the winning team (and their spouses) are to go to Brazil, expenses paid, to oversee the construction. All along the design stages, Stoev's understanding has been that he would be going together with his loyal and equally gifted assistant architect. However, the company chief secretly decides to change the terms and go instead of the assistant, threatening Stoev to cancel the whole deal if he doesn't comply. Stoev is left with the dilemma to betray a colleague and friend, or to miss the greatest opportunity in his career (and face the wrath of his nagging overambitious wife). When Stoev is about to choose the former, a mysterious dead body appears in his life, forcing him to take a deeper look into himself and society.

Release and acclaim
The film premiered on 10 April 1989 in Bulgaria. The film was produced by Boyana Film.

Dichloroisocyanuric acid. Dichloroisocyanuric acid, also known as dichlor or dichloro-s-triazinetrione and is marketed under many names (e.g. troclosene), is a chemical compound with the formula (C(O)NCl)2(C(O)NH).

Synthesis
Dichloroisocyanuric acid is manufactured by chlorination of cyanuric acid:
(C(O)NH)3  +  2 Cl2   →   (C(O)NCl)2(C(O)NH)  +  2 HCl
It is a colourless solid.

Mechanism of action

Dichloroisocyanuric acid is an oxidizer, reacting with water to form chlorine gas.

Although the bleaching agent in most chlorine based bleach is sodium hypochlorite, the sodium salt of dichloroisocyanuric acid, sodium dichloroisocyanurate, is the active ingredient in commercial disinfectant bacteriocides, algicides, and cleaning agents such as the pulverized cleanser Comet.
