Oxonitridosilicate. The oxonitridosilicates, also called sions (Si + O + N) or silicon-oxynitrides  are inorganic ceramic compounds in which oxygen and nitrogen atoms are bound to a silicon atom. A common variant also has aluminium replacing some silicon. They can be considered as silicates in which nitrogen partially replaces oxygen, or as nitridosilicates with oxygen partly replacing nitrogen.

Formation
A possible way to make these compounds is to heat metal oxides or carbonates with silicon nitride and silica in a nitrogen atmosphere.

Properties
Oxonitridosilicates have diverse structures. At the small scale silicon forms tetrahedral shapes surrounded by four oxygen or nitrogen atoms. With oxygen, one point of a tetrahedron can be bridged to another denoted O[2], or the oxygen can be a terminal atom denoted O[1]. With nitrogen, it can be shared in more ways: terminal N[1], bridged between two tetrahedra N[2], or even three or four: N[3], N[4]. With nitrogen, tetrahedra can be fused on an edge, or a point, whereas oxygen only connects tetrahedra at a vertex.

The condensation ratio, denoted by K indicates how condensed the tetrahedra are. K is the number of silicon atoms divided by the sum of oxygen and nitrogen. For SiN48− or SIO24+ K is 1/4 and it increases to 1/2 for SiO2.

Use
Oxonitridosilicates doped with europium have been used as phosphors in white LEDs, as they convert some blue light to other colours that can mix to white.

Otto A.G.O. 80/100 hp. The Otto A.G.O. 80/100 hp aircraft engine from 1911 was a four-cylinder, water cooled inline engine built by the German Gustav Otto Flugmaschinenwerke.

Design and development

The Otto A.G.O. (Aeromotor Gustav Otto) 80/100 hp engine was designed by Hans Geisenhof in 1911 at the Gustav Otto Flugmaschinenwerke.
It had a bore and stroke of  and was rated at  with a normal speed of 1,200 rpm.

As with the smaller Otto A.G.O. 50 hp engine, the cylinders were cast separately from iron and then machined. They were grouped together to a single block, joined at their cooling jackets by means of flanges and bolts.
The conjoined cylinder block incorporated a single intake duct running through the water jackets, fed by a single carburettor which was installed at the control end.
There were two overhead valves per cylinder, which were operated via pushrods and rocker arms from the camshaft on the left side of the engine, with the camshaft being driven from the crankshaft by spur gears at the control end.
The magneto also was located at the control end of the engine to the right, driven from the crankshaft via an intermediate spur gear.

The crankshaft was supported by three intermediate and two outer plain bearings, with two additional thrust ball bearings at the propeller end.
Lubrication was pressure fed, with an oil pump feeding oil to the crankshaft bearings.

In 1912 the engine was also produced as a six-cylinder with the same cylinder dimensions, rated at .

ENS Tahya Misr. ENS Tahya Misr (FFG 1001) is a FREMM multipurpose frigate of the Egyptian Navy. Tahya Misr was originally constructed as the Aquitaine-class Normandie before being acquired by Egypt and being renamed.

Development and design 
Three original variants of the FREMM were proposed; an anti-submarine variant (ASW) and a general-purpose variant (GP) and a land-attack variant (AVT) to replace the existing classes of frigates within the French and Italian navies. A total of 27 FREMM were to be constructed - 17 for France and 10 for Italy - with additional aims to seek exports, however budget cuts and changing requirements has seen this number drop significantly for France, while the order for Italy remained unchanged. The land-attack variant (AVT) was subsequently cancelled.

On 16 February 2015, the Egyptian Navy ordered one FREMM vessel to enter service before the opening of the New Suez Canal, as part of a larger deal (including 24 Rafales and a supply of missiles) worth US$5.9 billion (€5.2 billion). The SYLVER A70 VLS and NETTUNO-4100 jamming equipment were removed due to export limitations for such sensitive equipment. The crew will be around 126 sailors compared to 108 in the French Navy. The SATCOM antenna for the French Syracuse satellites was also taken down; however, Egypt will use its own military telecommunications satellite, supplied by Airbus Defence and Space and Thales Alenia Space, in conjunction with its naval vessels. From March 2015, DCNS trained the Egyptian crew in the technology of the ship and DCNS and its partners accompanied the crew for a period of 15 months.

Construction and career 
In order to keep to Egypt's deadlines, France offered to send Normandie, originally intended for the French Navy. On 23 June 2015, French naval shipbuilder DCNS transferred the FREMM frigate Tahya Misr ( ex-Normandie) to the Egyptian Navy. A ceremony took place to transfer Normandie, renamed Tahya Misr ("Long Live Egypt") to Egypt, in the presence of General Sedki Sobhy, the Egyptian Minister of Defense, Jean-Yves Le Drian, the French Minister of Defense, Admiral Osama Rabie, Egyptian Navy Commander in Chief, Admiral Bernard Rogel, the French Chief of Navy and Hervé Guillou, Chairman & CEO of DCNS. The frigate sailed for the first time under the Egyptian flag on 24 June 2015, and as the flagship of the fleet on 6 August, it participated in the inauguration of the new Suez Canal.

In August 2018, Tahya Misr carried out a joint exercise with the similar , returning home after having participated in Operation Atalanta in the Indian Ocean.

Light resin transfer moulding. Light resin transfer moulding (Light RTM) is a process by which products of Composite materials are manufactured using a closed mold system.

Procedure 
Similar to the methods performed in resin transfer molding, Light RTM involves a closed mold process. A vacuum holds mold A and mold B together to result in two finished sides with fixed thickness levels. Vacuum rings around the tools hold the molds together for this process after dry fiber reinforcements are loaded into mold A before joining with mold B. 

The air is vacuumed out of the molds with a lower vacuum level, separate from the tooling. After the air is removed the resin is injected into the part. The vacuum remains in effect into the resin is cured.

Richard Price-Williams. Richard Price-Williams (1827–1916) was a British engineer.

Biography

Richard Price-Williams was born in London on 22 November 1827. He served a pupillage under George Heald, who was Thomas Brassey's engineer on the construction of the Lancaster & Carlisle, and Caledonian Railways in 1845–1846. He afterwards served as an apprentice in the locomotive works of Kitson, Thompson and Hewitson at Leeds, being engaged later on, from 1854 to 1860, in designing and preparing plans of girder bridges, and carrying out other works while resident engineer at Leeds on the Great Northern Railway. Subsequently, he acted as consulting engineer for the proposed Metropolitan Outer Circle Railway, and in the preparation of plans and estimates for a number of other railways, both at home and in the Colonies.

He was appointed by the Royal Commission on Coal Supplies in 1866 and subsequent years and in 1868 he was appointed Chief Engineer  for the Royal Commission on Irish Railways. He also acted for most of the principal railway companies in the United Kingdom to prepare and advocate their claims against the Government for the purchase of the telegraphs in 1871.

In 1872 his Railway Map of England & Wales was published by Edward Stanford of Charing Cross, London.

In 1889 he reported upon the condition of the railways in New South Wales and Tasmania, and afterwards acted as arbitrator on behalf of the Tasmanian Main Line Railway Co. for the disposal of the railway to the Tasmanian Government, being subsequently appointed Consulting Engineer by the Governor.

He became a Member of the Institution of Civil Engineers in 1861, and was awarded the Telford, Watt, and Stephenson gold medals. The Iron and Steel Institute awarded him the Bessemer gold medal in 1898 on the recommendation of Sir Henry Bessemer.

He died at Bournemouth on 19 September 1916.

Chinese destroyer Kunming. Kunming (172) is a Type 052D destroyer of the People's Liberation Army Navy. She was commissioned on 21 March 2014.

Development and design 
The basic ship type and layout of the Type 052D guided-missile destroyer is the same as that of the Type 052C destroyer, but compared to the earlier Type 052C destroyer, the Type 052D superstructure has a larger inclination angle and provides better stealth performance. At the same time, the Type 052C helicopter hangar is located on the left side of the hull axis. This was changed to the center axis of the ship on the Type 052D; a pair of small boat storage compartments were added on both sides of the hangar, similar to the design on the Type 054A frigate.

The close-in weapon system is composed of a H/PJ-12 short-range defense weapon system located in front of the bridge and a 24 Hongqi-10 air defense missile system located on the top of the hangar, which is combined to form a ladder interception. The original  naval gun was replaced by a higher height and better stealth model H/PJ45 naval gun. On 13 May 2019, the extended version of the Type 052DL was exposed. The hull of the Type 052DL is basically the same as the Type 052D, but the helicopter deck is lengthened to prepare for the Zhi-20 to board the ship.

The Type 052D is the first Chinese surface combatant to use canister-based universal vertical launch system (VLS), as opposed to the concentric type VLS carried aboard earlier vessels. 64 cells are carried; 32 forward and 32 aft. The VLS is reportedly an implementation of the GJB 5860-2006 standard. The VLS may fire the extended-range variant of the HHQ-9 surface-to-air missile, YJ-18 anti-ship cruise missiles, and CY-5 anti-submarine missiles.

Construction and career 
Kunming is the lead ship of the class and was laid down on 16 February 2012 at the Jiangnan Shipyard in Shanghai. She was launched on 29 August 2012 and commissioned on 21 March 2014.

On 26 October 2015, a United States Navy destroyer approached within  of Chinese islands and reefs in the South China Sea. Kunming was sent to surveil the American ship.

Flight Commander 2. Flight Commander 2 is a 1994 computer wargame developed by Big Time Software and published by Avalon Hill. It was designed by Charles Moylan.

Gameplay
Flight Commander 2 is a computer wargame that simulates aerial warfare at the tactical level.

Development
Flight Commander 2 was designed by Charles Moylan, later responsible for Combat Mission. It is the sequel to Moylan's board wargame Flight Commander, which William R. Trotter of PC Gamer US wrote had "gained a small but fanatical following, even though it was too complicated to capture a large market."

The game was released for Mac computers in November 1994.

Reception

Flight Commander 2 sold fewer than 50,000 units globally. This was part of a trend for Avalon Hill games during the period; Terry Coleman of Computer Gaming World wrote in late 1998 that "no AH game in the past five years" had reached the mark.

William R. Trotter of PC Gamer US gave Flight Commander 2 a positive review, calling it a "thoughtful, intelligent simulation, and one that really has no current competition."

In 1996, Computer Gaming Worlds wargame columnist Terry Coleman named Flight Commander 2 his pick for the 15th-best computer wargame of all time. In 2017, Tim Stone of Rock, Paper, Shotgun wrote that the game's "brilliant design still hastens heart rates and evaporates evenings more effectively than any other winged wargame I know."

Legacy
Charles Moylan continued working with Avalon Hill on the aerial combat wargames Over the Reich (1996) and Achtung Spitfire! (1997). He went on to found Battlefront.com and designed the game Combat Mission: Beyond Overlord.

Impulse 21. The Impulse 21, built by Impulse Marine Inc is an American trailerable sailboat that was designed by William E. Cook as a one-design racer and day sailer, It was first built in 1986.

Production
The design was initially built by Impulse Marine in the United States. After the first 10-12 boats were completed, it was then built under contract by Johnson Boatworks on behalf of Impulse Marine. A total of 150 boats were completed, but it is now out of production.

Design
The Impulse 21 is a recreational keelboat, built predominantly of fiberglass, with a Klegecell core. It has a fractional sloop rig, a raked stem, a cut-out, walk-through, sharply reverse transom that allows ease of boarding, an internally mounted spade-type rudder controlled by a tiller and a fixed fin keel. It displaces  and carries  of ballast.

The boat has a draft of  with the standard keel.

The design has only a small cuddy cabin for sail and cooler stowage and no sleeping accommodation.

For sailing the design is equipped with a cockpit that is  long. It has a launcher tube for a spinnaker of  and a self-tacking jib. The boat is equipped with foam-fill compartments for buoyancy.

The design has a Portsmouth Yardstick D-PN racing average handicap of 183.

Operational history
In a 1994 review Richard Sherwood wrote, "a day sailer with room for lots of crew, the Impulse’s most unusual feature is a center console housing the control lines for the jib sheet, jib traveler, jib Cunningham, main Cunningham, boom vang, spinnaker halyard, spinnaker retriever, and backstay adjustments. The cockpit is 9 feet long, with seating on the wide decks ... Keel depth is moderate, so that Impulse may be trailered. However, the keel, taken with the wide beam and deck, provides good stability, and foam-filled compartments provide flotation."
