N-Methyltaurine. N-Methyltaurine (2-methylaminoethanesulfonic acid) is an aminosulfonic acid which is present as a zwitterion in the crystalline state and in polar solvents (just like amino acids). In contrast to the widespread taurine, N-methyltaurine has been found in nature only in red algae, where it is formed by methylation of taurine. It is suitable for esterification (actually amide formation) with long-chain carboxylic acids to taurides (acylaminoethansulfonaten) because of its high polarity and the relatively good solubility of its alkaline earth metal salts, which are also used as mild anionic surfactants.

Preparation 
The synthesis of N-methyltaurine was reported as early as 1878, with methylamine being reacted with the silver salt of 2-chloroethanesulfonic acid. An obvious modification for this reaction is the replacement of the silver salt of 2-chloroethanesulfonic acid by the sodium salt of 2-chloroethanesulfonic acid. The addition of methylamine to sodium vinylsulfonate in aqueous solution gives N-methyltaurine in 85% yield after acidification with acetic acid. The purification of the crude product and preparation of the N-methyltaurine can also be accomplished by passage of the sodium salt solution through a cation exchange resin in its H form and then through an anion exchange resin in its OH form. The reaction of sodium isethionate with methylamine in water at high temperature and pressure yields the sodium salt of N-methyltaurine

which yields pure N-methyltaurine upon saturation with CO2 and removal of the precipitated sodium bicarbonate.

Properties 
N-Methyltaurine is a white powdery solid which is readily soluble in water.

Use 
N-Methyltaurine (or its sodium salt) is used as a polar head group in surfactants from the class of taurides (acylaminoethanesulfonates), sometimes also called methyltaurates. The Taurides are characterized by excellent foaming - even in the presence of oil and skin fats - and foam stability, with good skin compatibility and broad pH stability. The market breakthrough for N-methyltaurine as a hair restorer is still pending.

Lethal synthesis. Lethal synthesis, or suicide metabolism, is the biosynthesis of a toxin from a precursor which is not itself toxic, such as the synthesis of fluorocitrate from fluoroacetate or the synthesis of methylglyoxal from glycerol.

The term was first publicised by Rudolph Peters in his Croonian Lecture of 1951.

Lethal synthesis of methylglyoxal 
A 1971 study published by the Harvard Medical School identified methylglyoxal, a form of glycerol, as a product of lethal synthesis in a specific E.coli mutant. In E.coli, the synthesis of triose phosphate from glycerol is a reaction regulated by the synthesis rate of glycerol kinase and by feedback inhibition by fructose-1,6-bisphosphate. The study demonstrated that, in E.coli mutants that had lost both control mechanisms, glycerol kinase no longer reacted to feedback regulation and instead produced the cytotoxic methylglyoxal. A more recent review of research done on methylglyoxal metabolism concluded that the compound's cytotoxic nature is dependent on its ability to form advanced glycation end products (AGEs). These compounds, which are thought to be factors in ageing and in the progression of degenerative diseases, have been shown to hinder the functions of the proteins they target.

Sdaw. Sdaw is a 1990 action game developed by Fabrice Caillaud, Lionel Caillaud and Arnaud Dewilde, and published by Lankhor for the Amstrad CPC.

Plot 
The world has been destroyed by a global disaster (World War III), and most of the humans have turned into mutants. A few survivors created a perfect robot named S.D.A.W. (System de Defense Anti-Wobblegobbledigook). Players take control of S.D.A.W. and live in sewers. They have been given a mission to clean the area of its unwanted occupants by restraining and disarming them.

Development 
Sdaw has a 16 colour palette and the game world's labyrinth has around 200 screens. its use of "mode 0" allowed for graphics that were very difficult to find at the time.

Reception 
Sdaw received an 82% from Amstrad 100%, 60% from Joystick, and Tilt gave it a B.

MicroNews felt that a bit of extra care to the design, for instance in its animations, would have livened up the game.

Suswa–Isinya–Rabai High Voltage Power Line. Suswa–Isinya–Rabai High Voltage Power Line is an operational high voltage (400 kilo Volts) electricity power line connecting the high voltage  substation at Suswa, Kenya to another high voltage substation at Rabai, Kenya.

Location
The power line starts at Suswa, in Narok County, about , by road, north-west of Nairobi, and runs in a south-easterly direction for approximately  to the Ketraco Power Substation at Isinya, in Kajiado County.

From Isinya, the power line follows a south-easterly course to end at Rabai, in Kilifi County, approximately , away, as the crow flies. The power line measures about .

Overview
The original plan was to build a 220 kilo Volt transmission line. Plans were later revised and the voltage was increased to 400kV. The line serves three main purposes: (a) It transmits power generated from geothermal power stations in the Eastern Rift Valley, to Kenya's coastal region (b) It transmits power from thermal power stations near the coast to the industrial centers in and near Nairobi (c) Through Suswa, the power line connects to Lessos and Tororo, Uganda, allowing the export of electricity to Uganda and Rwanda.

Construction
Construction started in August 2011, with the Rabai–Isinya section. Construction was budgeted at KSh14 billion (US$140 million), funded with loans from (i) the French Development Agency (ii) the European Investment Bank and (iii) the African Development Bank. The Government of Kenya, invested equity in the project. Kalpataru Power Transmission Limited (KPTL) from India, was the lead contractor on this project. Siemens was the substation contractor. After delays, the power line came on-line in the second half of 2017.

Taganrog Aviation Museum. Taganrog Aviation Museum () is one of the eleven Aviation museums in Russia and is the only one of its kind in Southern Russia.

History 
Since 1948, the 325th Aviation Repair Plant (325th ARP) is located at the Taganrog-Central air base. The Aviation Museum currently belongs to ARP.

The 325th ARP repairs of An-12, An-72 transport aircraft and equipment for Il-76, Tu-142, Su-25, Su-27, Mi-8 and Mi-24 helicopters.

However, in the early 1990s, the 325th ARR had one more task: it was to create a "Base for the destruction of Aviation Equipment of Frontline Aviation". This happened according to the Treaty on Conventional Armed Forces in Europe, signed in 1990. Under this agreement, many combat aircraft from the USSR Air Force, and later the Russian Air Force, were to be disposed of. Lieutenant Colonel Vladimir Stoyanov and the commander of the base, Colonel Alexander Kornienko, appealed to the command of the 4th Air Army with the proposal to keep at least one exemplar of each type of aircraft entering the dismantlement, removing their engines and airborne systems. According to the idea of Stoyanov, the rescued machines were to become a base for the Taganrog Museum of Aviation. The commander of the 4th Air Army Vladimir Sergeyevich Mikhaylov approved their idea. On 23 April 1995 he ordered to save MiG-21bis, MiG-23M, MiG-25BM and Su-22 from utilization programme. Soon new aircraft were acquired: Aero L-39 Albatros, Aero L-29 Delfin  Yak-38 and An-2.

Currently the exhibits include 12 types of aircraft. One exhibit is the MiG-25BM, of which only 40 examples were constructed, and the one that is on display in Taganrog seems to be the only one that survived.

Visitors are allowed to get inside each aircraft. As of 2022 the museum keepers were trying to acquire City Status for their museum.

Quartz fiber. Quartz fiber is a fiber created from high-purity quartz crystals. It is made by first softening quartz rods (in an oxyhydrogen flame) and then creating filaments from the rods. Since the creation of high-purity quartz crystals is an energy intensive process, quartz fiber is more expensive than alternatives (glass fiber and high-silica fiber) and has limited applications.

Manufacture 
Quartz fiber is made from heating quartz rods with an oxyhydrogen flame. Then, filaments are drawn out of the quartz rod, creating quartz fibers. For optical fibers, germanium and phosphorus can be added to increase the refractive index.

Properties 
A single quartz fiber can have a tensile strength of . Quartz fibers are chemically stable as they are not affected by halogens (for the most part). Quartz fibers also have a higher thermal resistance than S-glass or E-glass.

Applications 

Since quartz fiber is expensive, it has limited applications. It is used mainly for producing composite materials (due to having higher stability compared to glass fiber) and in electrical applications where thermal resistance and dielectric properties are important. It can be used in filtration applications where alternatives such as glass fiber filters cannot be used. Quartz fiber can also be used for physical devices (such as in quartz fiber dosimeters and quartz fiber electrometers).

Quartz fibers can be used in fiber optics. This is due to a quartz fiber having the ability to transport data at a speed of 1 terabit per second, and having a transmission loss of 1 decibel per kilometer.

Similar to how fiberglass can be made, quartz fiber can be used to make composite materials by combining with a resin. The fiber can be weaved into a cloth ("quartz cloth", "silica cloth"), or chopped to a uniform length. Three-dimensional quartz phenolic is an example of such a material.

Thermostad. A thermostad is a homogeneous layer of oceanic waters in terms of temperature, it is defined as a relative minimum of the vertical temperature gradient.
The term was coined in 1966 by R. Carlton Seitz, at the time at the Chesapeake Bay Institute of Johns Hopkins University.
He proposed it as in opposition to a thermocline, in which the thermal gradient is large. The ending "stad" is from the Greek word στάδην meaning "in an upright position", from the root ἵστημι meaning to stand.

The suffix "-stad" is now widely used in oceanography.
