Henri Rouart. Stanislas-Henri Rouart (2 October 1833, Paris – 2 January 1912, Paris) was a French engineer, industrialist, art collector and painter.

Biography 
His father was a wealthy manufacturer of military uniforms. He was a student at the Lycée Louis-le-Grand, where he became a friend of Edgar Degas. Later, he attended the École Polytechnique and studied engineering, but also took art classes. He was an artillery captain in the Franco-Prussian War, and rescued Degas during the Siege of Paris.

He was involved in numerous engineering projects, including tubes for the Paris pneumatic post, a prototype for making "artificial ice", and an engine with external fins for cooling. In his fifties, having participated in the occasional exhibition since 1868, he decided to devote himself entirely to painting. A former student of Corot and Millet, his works were largely Impressionistic in nature.

In addition to painting, he was an avid art collector and a patron of several artists, including Berthe Morisot, Toulouse-Lautrec, and Renoir, as well as his old friend, Degas. Three exhibitions of Impressionist works were held, thanks to his financial support.

In 1891, he was elected Mayor of La Queue-en-Brie, in Val-de-Marne; a position he held until his death. After almost a year following his death, his daughter and four sons decided to sell his collection. The sale brought in a huge sum, and had the effect of increasing the value of Impressionist paintings in general. One of his sons, Ernest, also became a painter.

Honoured Navigator of the USSR. The Honorary Title "Honoured Navigator of the USSR" () was a civilian state award of the Soviet Union established on September 30, 1965 by Decree of the Presidium of the Supreme Soviet of the USSR № 3993-VI to recognise excellence in civilian aviation.  It was abolished on August 22, 1988 by Decree of the Presidium of the Supreme Soviet № 9441-XI.

Award Statute 
The honorary title "Honoured Navigator of the USSR" was awarded to qualified civilian navigators 1st class for special merit in the development of modern aircraft, in the use of the most advanced navigating techniques, for the highest standards in education and training of flight personnel, for long-term trouble-free flying and for outstanding achievements in the use of aviation in the national economy.

The Presidium of the Supreme Soviet of the USSR was the main conferring authority of the award based on recommendations of the Minister for Civil Aviation of the USSR.

The chest badge "Honoured Navigator of the USSR" was worn on the right side of the chest and in the presence of other orders, placed over them. If worn with honorary titles of the Russian Federation, the latter have precedence.

Award Description 
The "Honoured Navigator of the USSR" chest badge was a 27mm wide by 23mm high silver and nickel polygon with raised edges. At the top of the obverse, the relief inscription in two lines covered to the left "HONOURED NAVIGATOR" (Russian: ЗАСЛУЖЕННЫЙ ШТУРМАН), in the center, the gilt tombac image of a jet transport aircraft climbing diagonally towards the right, at the bottom, the relief inscription "USSR" (Russian: СССР) superimposed over a laurel branch.

The badge was secured to a standard Soviet square mount by a silver-plated ring through the suspension loop. The mount was covered by a red silk moiré ribbon.  It was secured to clothing with a pin attachment or with a threaded stud and nut.

Metallic soap. A metallic soap is a metallic salt of a fatty acid. Theoretically, soaps can be made of any metal, although not all enjoy practical uses. Varying the metal can strongly affect the properties of the compound, particularly its solubility.

Alkali, alkaline earth soaps

Alkali metal and alkaline earth soaps are white solids. The most commonly encountered are traditional household soaps, which are the fatty acid salts of sodium (hard soap) and potassium (soft soap). Lithium soap or greases, such as lithium stearate, are insoluble in water and find use in lubricating grease. 

Calcium and magnesium soaps are most commonly encountered as soap scum but the pure materials have a variety of uses. Magnesium stearate and calcium stearate are used as excipients, lubricants, release agents, and food additives, with the later use being covered by the generic E numbers of E470b and E470 respectively.

Other metal soaps
Aluminium soaps are used as thickening agents, in the production of cosmetics. Other examples include mixed calcium/zinc soaps which are used as heat stabilizer for polyvinyl chloride.  Soaps of iron, cobalt and manganese are used as drying agents in paints and varnishes and work by promoting the oxidation and crosslinking of unsaturated oils.

Catamount (operating system). Catamount is an operating system for supercomputers. 

Catamount is a lightweight kernel that provides basic functionality and aims for efficiency. The roots of Catamount go back to 1991 when SUNMOS was developed by Sandia National Laboratories and the University of New Mexico as a lightweight operating system. The Cray XT3 uses Catamount on compute nodes and Linux on server nodes.

A case study by the IEEE assessed the performance of a particle transport code on AWE's Cray XT3 8,000-core supercomputer  while running images of the Catamount and the Cray Linux Environment (CLE) operating systems. This work demonstrated that by running a number of small benchmarks on a test machine it is possible to speculate as to the performance impact of upgrading from one operating system to another on the system as a whole. The study's findings enabled researchers to minimise system downtime while exploring software upgrades. The results show that benchmark tests run on less than 256 cores would suggest that the impact of upgrading the operating system to CLE was less than 10%.

Air-mixing plenum. An air-mixing plenum (or mixing box) is used in building services engineering and HVAC construction for mixing air from different ductwork systems.

Usage 
Air streams are mixed to save energy and improve energy efficiency by partially recirculating conditioned air.

The most common application for an air-mixing plenum is the mixing of return air (or extract air) with fresh air to provide a supply air mixture for onward distribution to the building or area which the ventilation system is serving. The air transferred from the return air stream to the supply air stream is termed recirculated air. All air not mixed is rejected to the atmosphere as exhaust air.

Operation 
The mixing plenum normally combines two air streams, and includes for three sets of dampers: one for the fresh air, one for the exhaust air, and a mixing damper between the two air streams. The mix of fresh air and recirculated air can thus be adjusted to suit the needs of the building's occupants. Most systems will use motorized dampers to control the air mixing, and controlled by the building management system (BMS), or controls system. Typically as the fresh air and exhaust air dampers are driven from 0% open to 100% open, the mixing damper will in turn be driven from 100% open to 0% open, so as to always ensure a constant volume of supply and extract air.

Energy efficiency 

Air supply to a building is generally performed by an air handling unit. The process may include filtering, heating, cooling, humidification, or dehumidification, all of which consume energy. Since building occupants demand less than 100% fresh air, only a fraction of that amount is admitted to the system, with and equal amount of treated air exhausted to the atmosphere; fresh air is mixed with conditioned air in a plenum.

Enhanced controls systems may monitor the return air quality or carbon dioxide concentration in order to automatically modulate the air mix for optimum energy efficiency while maintaining desired fresh air requirements. Such systems work very well in buildings where the occupancy rate can vary greatly throughout the day, or seasonally. Additionally, when outside air conditions are such, typically mid-season weather conditions, it may be that ambient temperatures are suitable for free cooling purposes. In such conditions the mixing damper will be set to close and the system use full fresh air for optimum energy efficiency. Where fresh air is not required, such as early morning pre-heat or pre-conditioning periods, the mixing damper can be automatically set to full recirculation, again for optimum energy efficiency.

LNWR Class G. The London and North Western Railway (LNWR) Class G were several related classes of 0-8-0 steam locomotives. These 0-8-0s were the principal work-horses for freight traffic on the latter-day London & North Western.

History 
32 of this class were rebuilt from 4-cylinder compound Class B between 1906 and 1917.  The outside high-pressure cylinders were removed and the inside low-pressure cylinders were re-used, in their original position, to make a two-cylinder simple expansion engine. The boiler pressure was reduced from 200 psi to 160 psi to keep the tractive effort approximately the same.  The rebuilt engines retained their old numbers. Additionally, 60 new Gs were built in 1910. The rebuilt engines were easily distinguished from the new builds by having "piano fronts".

Rebuilding 
The first of the class, LNWR No. 2653, was rebuilt to Class G1 in 1912.  The remaining 91 engines were inherited by the LMS in 1923.  LMS numbers were 9077-9144. The LMS rebuilt them all to Class G1 between May 1924 and 1937, thus rendering the class extinct.

Cryometer. A cryometer is a thermometer used to measure very low temperatures of objects. Ethanol-filled thermometers are used in preference to mercury for meteorological measurements and can measure temperatures in the range of . Their main physical limitation is the freezing and boiling point of the liquid used.

There are many types of devices used as cryometers to measure temperatures below the freezing point of common liquids:
thermocouples: these can be used down to measure about 1 K temperature.
vapour pressure thermometers: these can be used to measure temperatures down to about 0.5K
resistance thermometers: these can be used to measure temperatures at 0.01 K.
melting curve thermometers: these can be used to measure temperatures between about 0.001K and 0.5K
resistance noise thermometers: these can be used to down to about 0.001K
magnetic thermometers: which are used at 0.001 K temperatures.
nuclear-resonance thermometers: these are required to measure very low temperatures such as 0.0000001 K.
