Malaysian Space Agency. The Malaysian Space Agency (), abbreviated MYSA, is the national space agency of Malaysia. On 20 February 2019, the Malaysian Cabinet had approved the establishment of MYSA through the merging of Malaysian Remote Sensing Agency (MRSA) and National Space Agency (ANGKASA).

In March 2019, the Minister of Energy, Science, Technology, Environment and Climate Change, Yeo Bee Yin said MYSA would focus on technology, infrastructure and strategic space application development. It would be tasked with gathering comprehensive satellite data and information systems to assist various public agencies effectively in terms of environment, natural resources, food security, disaster management and climate change management. The collected data and information can be shared with the private sector, to help them develop and achieve their own modelling system. The merge of MRSA and ANGKASA into one agency would improve work efficiencies by optimising the use of existing resources and facilities.

, the director general is Tuan Haji Azlikamil Napiah.

Aluminium monohydroxide. Hydroxyaluminium(I), also known as Aluminium(I) hydroxide, is an inorganic chemical with molecular formula AlOH. It consists of aluminium in the +1 oxidation state paired with a single hydroxide. It has been detected as a molecular substance in the envelope of an oxygen-rich red supergiant star, a place where substances containing metals or hydroxides are thought to be rare.

Production
In the laboratory AlOH can be made by heating aluminium, so that it vapourises into low pressure hydrogen peroxide vapour. Another method is to condense a mixture of aluminium vapour, hydrogen and oxygen with argon into a solid at 10K. Along with AlOH, there are also Al(OH)2, Al(OH)3, HAl(OH)2, cyc-AlO2 and AlOAl molecules formed.

Properties
The bond lengths are, Al-O 1.682 Å, and for O-H 0.878 Å. The rotational constants are B0=15,740.2476 MHz and D0=0.02481 MHz.

Franklin Sport. The Franklin Sport is a two seat sport and training biplane built in the U.S. in 1930. Several different engines, in the power range , were fitted. Two remained airworthy in 2011.

Design and development

The Sport is a single bay, unequal span biplane. Its wings are built around twin spruce spars and, like the rest of the aircraft, fabric covered. Upper and lower wings have the same chord and outward-leaning, N-form interplane struts between their spars provide a wide interplane gap of about . The upper wing is without dihedral but the lower, equipped with Frise ailerons, is set at 2°. Both wings are rectangular in plan out to rounded tips though the upper wing, held centrally over the fuselage on a cabane, has a semi-circular cut-out to increase the pilot's upwards field of view.

All the Sport variants were powered by one of three types of five cylinder radial engine, nose-mounted on a frame which allowed easy exchanges between types. The fuselage has a flat-sided steel tube Warren girder structure with two open cockpits, one between the wings and the other just aft of the upper trailing edge with an extended, faired headrest. It is normally piloted from the rear seat, though the forward cockpit also has flight controls. Some instruments like the fuel gauge are visible from either seat. At the rear the tail also has a steel tube structure. The tailplane and elevators are mounted on top of the fuselage and the fin and unbalanced rudder have a rounded profile.

The landing gear is fixed and of the split axle type, with mainwheels on V-struts from the central fuselage underside and with vertical oleo struts from the outer axle to the wing leading edges, where single bracing struts connect to the upper fuselage longerons. A short tailskid is mounted on the extreme rear fuselage.

Operational history

The Sport prototype, powered by a  Velie M-5 engine, first flew on 27 January 1930. After tests this was abandoned and production aircraft had either a  M-5 (Sport A, 8 built) or a  Lambert R-266 (Sport 90, 6 built) engine.

The histories of most of these club aircraft is uncertain. Further production ended in 1933 when Franklin Aircraft ceased trading. Two, both Sport 90s, remained airworthy in U.S. museums in 2011, though only one was on public display.

List of keyboard switches. 

Commonly used mechanical switches on pre-built keyboards 

Manufacturers frequently build computer keyboards using switches from original equipment manufacturers (OEMs). The switches used determine the feel of the keyboard.

Mechanical keyboard switches for custom keyboards 
On the custom mechanical keyboard space, there are far greater quantity of keyboard switches. It is important to note that these do not portray the diversity and number of switches currently on the market.

Future 
As time goes on, there are more and more switches being developed and manufactured across the world. Some are by new manufacturers, some are collaborations between companies and manufacturers, and some are consumer made. Some  bigger databases that involve more than just our main manufacturers listed here.

On top of a variety of new switches being made, consumers are taking parts of different switches and then going on to make their own switches, called “Franken-switches.”

Branston Water Park. Branston Water Park is a local nature reserve near Burton upon Trent, in Staffordshire, England, adjacent to the village of Branston.

History
The lake is a former gravel pit, one of several along the Trent Valley. There was gravel extraction here from the 1930s to the 1950s, after which wildlife habitats developed naturally. In the mid 1980s the land was leased by East Staffordshire Borough Council; public access was introduced, and the site was developed as a country park, with pathways, signage and a visitor centre.

The reserve was designated a local nature reserve (LNR) in 2010. , it has held the Green Flag Award since 2005.

Description
The Trent and Mersey Canal passes alongside the site to the north-west; to the south- east is the A38 road.

Its area is . It is a notable wetland site, and around the lake is woodland, predominantly of willow and birch, and wildflower meadow. There is a large reed bed, which is a Grade 1 Staffordshire Site of Biological Importance.

There is a flat circular path around the lake, and there are picnic areas and a children's play area. The Burton Mutual Angling Association and the Burton Model Boating Club use the park by agreement with East Staffordshire Borough Council.

Worcester Engine Works Company. The Worcester Engine Works Company was a short lived British railway engineering company established in Worcester in 1864. Over the next nine years the company built locomotives for several British and European railway companies before the company went into voluntary liquidation in 1872 with the company being full liquidated by 1874.  The premises built by the company in Worcester still stand and are a Grade II listed building.

History
The Great Western Railway carriage works in Worcester were destroyed in a fire in 1864 and the railway company decided to move the work to Swindon  rather than rebuild in Worcester. A number of local businessmen, led by Alexander Clunes Sheriff, took the decision to provide employment for the men made redundant by establishing their own engineering works.  New locomotive works were built on Shrub Hill Road, close to  station.  For the first three years the company was profitable having received and fulfilling orders from the North Staffordshire Railway, Great Eastern Railway and Bristol & Exeter Railway companies as well as a small number of locomotives for contractors, two of which eventually ran on the Lwów-Czerniowce-Jassy Railway in Austria-Hungary.

After 1867 the effects of the economic panic of 1866 hit the company; orders dried up and lavish spending by the directors (mainly on the company buildings) saw the company make significant losses. A small return to profit was made in 1869 and a contract for the supply of 15 locomotives to the Nicolas Railway in Russia was obtained. But after the completion of the Russian order no further orders were received and the company made further losses resulting in the shareholders agreeing to voluntary liquidation in 1872, with the liquidation being complete by May 1874.

Suez Economic and Trade Cooperation Zone. The Suez Economic and Trade Cooperation Zone (SETC) is an industrial estate near the city of Suez, Egypt, established by a joint partnership between the governments of the People's Republic of China and the Arab Republic of Egypt, for the purposes of inviting Chinese companies to set up industries, as part of the Belt and Road project.

It was built by the Tianjin Economic-Technological Development Area (TEDA). The SETC zone was created in 2008 and extended in 2016 in a ceremony attended by CCP general secretary Xi Jinping on a state visit to Egypt.

The zone hosts several enterprises and manufacturing companies, including Jushi, which produces fiberglass in Egypt primarily for export  The EU introduced significant tariffs on fiberglass imports from Egypt as a result, alleging they were dumping the fiberglass.

Electroless copper plating. Electroless copper plating is a chemical process that deposits an even layer of copper on the surface of a solid substrate, like metal or plastic. The process involves dipping the substrate in a water solution containing copper salts and a reducing agent such as formaldehyde.

Unlike electroplating, electroless plating processes in general do not require passing an electric current through the bath and the substrate; the reduction of the metal cations in solution to metallic is achieved by purely chemical means, through an autocatalytic reaction.  Thus electroless plating creates an even layer of metal regardless of the geometry of the surface – in contrast to electroplating which suffers from uneven current density due to the effect of substrate shape on the electric field at its surface. Moreover, electroless plating can be applied to non-conductive surfaces.

Process
In a typical formulation of the process, the surfaces to be coated are primed with a palladium catalyst and then immersed in a bath containing copper ions , which are reduced by formaldehyde through the overall reactions
 +  →  (gas) +  +  2e
 + 2e →  (metal).

Applications

Electroless copper plating is used in the manufacture of printed circuit boards (PCBs), in particular for the  conductive layer on the walls of through holes and vias.

Rolls-Royce 40 mm cannon. The Rolls-Royce 40 mm Cannon was a project first proposed in late 1938 to produce a cannon for mounting in aircraft which could cause sufficient damage to bring down a large bomber. It was envisaged as a suitable weapon for destroying tanks from the air. Experimental versions of the cannon were produced, including some with a magazine or belt feed for the ammunition. Examples were fitted to a Bristol Beaufighter and Hawker Hurricane for testing, although never used in action. Development of the aircraft cannon to iron out problems came to an end in 1943 when the Air Ministry lost interest in it and had started to favor the RP-3 rocket projectile as its preferred aircraft anti-tank weapon.

The gun was designed by Italian engineer Spirito Mario Viale, Rolls Royce's chief armaments designer, at Littleover, Derby. The gun was tested on a small testing range at Sinfin near the Derby works without the usual precautions like red flags. Later trials were at an Army range at Manorbier of a gun mounted on a 30 cwt Morris truck (which by a fluke hit a target plane on its fourth shot) and at the Royal Navy's waterborne trials off Whale Island.

Although the Rolls-Royce 40 mm cannon was never deployed in aircraft, with the Fall of France in 1940 the Royal Navy found itself lacking armament in its coastal craft to respond to German E-boats. The Admiralty became interested in the development of the 40 mm cannon as a weapon that could knock out an E-boat. The first sea trials of the cannon were undertaken in September 1940 and it entered service in 1941 after teething troubles were ironed out. The "Rolls gun" was deployed mainly on motor gun boats which were used in action in British waters and the Mediterranean, where they were much used in the anti-aircraft role. Over 600 40 mm cannon were manufactured under sub-contract by British United Shoe Machinery (BUSM) in Leicester, since Rolls-Royce was forbidden by Lord Beaverbrook, the Minister of Aircraft Production, to tie up resources on them.
