Decoupling (meteorology). In weather forecasting, decoupling is a process in which two adjacent layers of Earth's atmosphere stop interacting.

Process 
During the day when the sun shines and warms the land, air at the surface of the earth is heated and rises. This rising air mixes the atmosphere near the earth. At night, this process stops and air near the surface cools as the land loses heat by radiating in the infrared. If winds are light, air near the surface of the earth can become much colder, compared to the air above it, than if more mixing of air layers occurred.

Climate impacts 
In mountain valleys at high altitudes, such as those in the Cascade Mountains, decoupling may alter the localized impacts of climate change, as it causes a drastic change in surface and atmospheric temperatures. In coastal regions of the Greenland ice sheet, decoupling may simultaneously help conserve ice sheet mass while limiting new accumulation of ice.

Reckoning board. The reckoning board, also called a memory board or hole board, could be used on its own as a basic counting device or used with an abacus for engineering.

There were two types of reckoning board. The older type was a simple 10 × 10 grid of holes. A peg would be inserted into a hole and moved along, starting from the top and working downwards. It was used as a memory aid when counting certain units. For every sack of grain or bar of steel, the peg would be moved forward and after a day or a week, the total number counted could be seen.

The more advanced type had columns of holes, with the columns indicating place value.

Browett, Lindley & Co. Browett, Lindley & Co was a British engineering company established in 1886, which manufactured stationary steam engines used to power cotton mills and early power stations.

The company built the Sandon Engine Works, Clifford Street, Patricroft in 1890. The works was later extended in 1901 by the addition of a new erecting shop and boilerhouse.

In 1902, the company supplied eight large triple expansion steam engines, driving 775 kW Mather & Platt dynamos, to Salford Corporation for its Frederick Road generating station.

The company built engines for several Lancashire cotton mills including Alder Mill, Leigh, and Fernhurst Mill, Chadderton.

The Sandon Engine Works closed in 1921.

In 1931, the company was bought by George Cohen, Sons and Company.

A. A. Bere Tallo Airport. A.A. Bere Tallo Airport, previously known as Haliwen Airport  is located in Atambua, East Nusa Tenggara, Indonesia.

It changed its name in 2013, to match local government's regulation on airport naming.

History
The airport was a stop-over location in the early days of pioneering aviation for Bill Lancaster and Jessie Maude "Chubbie" Miller in 1927.  This journey was one of the longest flights made in a small aircraft and the first attempted flight between England and Australia.  However, the flight was overtaken by Bert Hinkler, who was the first to complete the journey. 

In 2006, the airport had a runway length of just 900 meters. It was extended several times, with plans to extend the runway to 2,500 meters eventually.

Ulrich Kortz. Ulrich "Uli" Kortz is a German chemist and professor, working in the area of synthetic polyoxometalate chemistry.

Biography

Ulrich Kortz obtained his education in Chemical Engineering in the period 1982–1989 and was awarded his Diplom from Darmstadt University of Applied Sciences. In the period of 1989–1995 he was working on his doctorate degree at Georgetown University in Washington, DC, under close supervision of Michael T. Pope. He spent his postdoctoral years with Dante Gatteschi at Florence University, Italy, from 1995 to 1996, and with Andre Tézé and Gilbert Hervé at Versailles University, France, from 1996 to 1997. In 1997 he was hired as assistant professor at the American University of Beirut in Lebanon, and he was promoted to associate professor in 2001. In 2002 he returned to Germany to join the newly established International University Bremen, now Constructor University, as associate professor and he was promoted to full professor in 2007.

Highlights

The Kortz group ("The POM Lab") has discovered the class of polyoxopalladates(II) in 2008 with the synthesis of {Pd13As8}, and the class of polyoxoaurates(III) in 2010 with the synthesis of {Au4As4}. Ever since they have systematically developed the field of polyoxo-noble-metalates further. They have also pioneered the chemistry of the wheel-shaped {P8W48} by preparing {Cu20P8W48}, which contains a highly symmetrical Cu20 core with copper(II) ions in three different coordination geometries, and another highlight example was {Fe16P8W48}. Kortz and his team have also discovered the dilacunary heteropolytungstate {GeW10} in 2006, and systematically explored its reactivity towards transition metal ions. They have also explored the reactivity of many other lacunary heteropolytungstates with d and f block metal ions, two highlight products being {Mn19Si6W60} and {Ce20Ge10W100}. The Kortz group has also reported on POMs with interesting magnetic properties. In the area of catalysis, they have reported mainly on olefin epoxidation, alkane/alkene oxidation, as well as oxidative and reductive water splitting. Finally, they are also interested in the biological properties of POMs.

Silyl modified polymers. Silyl-modified polymers (SMP; also silane-modified polymers, modified-silane polymers, MS polymers, silane-terminated polymers, etc.) are polymers terminating with a silyl group. SMPs are the main components in solvent-free and isocyanate-free sealant and adhesive products. Sealant products manufactured with silyl-modified polymers generally have most of the desirable properties of acrylic- or polyurethane-based products, including high opacity, short drying time, and good paint adhesion, as well as some key properties of silicone-based products, including adhesion to a wider range of substrate materials, higher temperature and UV resistance, higher elasticity, and greater resistance to bacteria and fungi.

MS polymers consist of a polyether backbone with dimethoxy-silyl or trimethoxy-silyl ends, with trimethoxy-silyl groups being more reactive. Backbones can be linear with single or double ends, or branched for an increased amount of cross linking. Precursors can also be varied in the molecular weight and  reactive silyl group concentration, resulting in variable cure times, strength, density, and hardness.

Curing process
The products cure from a liquid or gel state to a solid elastomer. Curing entails crosslinking by the hydrolysis of silyl ethers:
 2 RSi(OCH3)2R' + H2O → [RSi(OCH3)R']2O + 2 CH3OH

In a hydrolysis reaction, a catalyst and moisture is required to form an intermediate silanol, which then reacts to form siloxane linkages in a condensation process.

Akaflieg Braunschweig SB-12. The Akaflieg Braunschweig SB-12 is a single seat, Standard Class sailplane designed around 1980 by German technical university students to test out a new wing profile from the German Aerospace Centre.  It was not intended for production, but the sole SB-12 remains active in 2010.

Design and development

The Akaflieg Braunschweig or Akademische Fliegergruppe Braunschweig () is one of some fourteen German student flying groups attached to and supported by their home Technical University.  Several have designed and built aircraft, often technically advanced and leading the development of gliders in particular.

The Brunswick students began the design of the Standard Class SB-12 in mid-1979 and the first flight was made on 9 April 1980.  It was not intended for production but to test out a new wing aerodynamic profile designed by the German Aerospace Centre (DFVLR) for high cruising performance.  The wing of the SB-12 has single, I-section spars, with carbon fibre flanges and GRP webs.  The skins are carbon fibre and polymeric foam. The wings are mounted at mid-fuselage at an incidence of 0.5° and with 3° of dihedral.  They carry GRP ailerons and wide span airbrakes but no spoiler or flaps.

The fuselage is a GRP monocoque with a front hinged canopy over the single seat cockpit and a tank for 150 kg (331 lb) of water ballast.  The SB-12 has a T-tail, with tailplane and elevators set on top of a straight edged, only slightly tapered fin and rudder.  The fixed surfaces are formed from GRP and plastic foam sandwich, the moving surfaces using only GRP.  Its undercarriage has a retractable, unsprung monowheel, fitted with an internal drum brake, with a fixed, partly recessed tailwheel.

Operational history

The sole SB-12, registration D-1225 and wearing HQ, for its airfoil, on the tail remained with Akaflieg Braunschweig until they sold it in 1989.  About ten years later it was sold to an owner in the German Alps and in 2007 sold again and returned to Brunswick. It remained on the German register in 2010.

Accumulative roll bonding. Accumulative roll bonding (ARB) is a severe plastic deformation (SPD) process. It is a method of rolling a stack of metal sheets, which are repeatedly rolled to a severe reduction ratio, sectioned into two halves, piled again and rolled. It has been often proposed as a method for the production of metal materials with ultrafine grain microstructure. ARB is a modification of repeated forging and folding method which has been in use since the end of Bronze Age or the beginning of Iron for sword making. The earliest works on modern ARB were by N. Tsuji, Y. Saito and co-workers. To obtain a single slab of a solid material, the rolling involves not only deformation, but also roll bonding.
