Japanese escort ship Matsuwa. was one of fourteen s built for the Imperial Japanese Navy during World War II.

Background and description
The Etorofu class was an improved version of the preceding  with a greater emphasis on anti-submarine warfare. The ships measured  overall, with a beam of  and a draft of . They displaced  at standard load and  at deep load. The ships had two diesel engines, each driving one propeller shaft, which were rated at a total of  for a speed of . The ships had a range of  at a speed of .

The main armament of the Etorofu class consisted of three Type 3  guns in single mounts, one superfiring pair aft and one mount forward of the superstructure. They were built with four Type 96  anti-aircraft guns in two twin-gun mounts, but the total was increased to 15 guns by August 1943. 36 depth charges were stowed aboard initially, but this later increased by August 1943 to 60 depth charges with a Type 97  trench mortar and six depth charge throwers. They received Type 22 and Type 13 radars and Type 93 sonar in 1943–44.

Construction and career
Matsuwa was launched by Mitsui, Tumano, on 19 April 1942 and completed on 1 April 1943. On 2 August 1944, she was torpedoed and sunk by the submarine  in Hidai Bay.

High-pressure chemistry. High-pressure chemistry is concerned with those chemical processes that are carried out under high pressure – pressures in the thousands of bars (100 kPa) or higher.  High-pressure processes are generally faster and have a higher conversion efficiency than processes at ambient pressure.  However, they are usually only beneficial on an industrial scale because of the investment in plant required.

The Haber–Bosch process produces ammonia from hydrogen and atmospheric nitrogen.  It was first demonstrated in 1909 and became an important industrial process for Germany during World War One when it played a part in the manufacture of explosives.  Today, it is mostly used to produce fertilizer.

The Bergius process produces hydrocarbon fuel from bituminous coal and hydrogen.  The process was first published in 1913 and was an important source of fuel for Germany during World War Two.  The process was used in the US for a while after the war, but there are currently no commercial plants in the world.

The Bergius process and the Haber-Bosch process were two pioneering methods of high-pressure chemistry.  The invention and development of these two processes led to the award of the Nobel Prize in Chemistry for 1931 jointly to Friedrich Bergius and Carl Bosch.

C.O.R.E. (video game). C.O.R.E. is a first-person shooter video game by Polish developer NoWay Studio that was released in Europe on March 27, 2009 and in North America on August 11, 2009.

Story
The story begins in the year 2028, when a massive meteor impacts California's Mojave Desert. Over the next two decades, an underground research facility is built to examine the extraterrestrial origins and the bizarre effects that the meteor is having on the natural environment and the people who come in contact with it. The game takes place twenty years after the meteor's arrival on Earth, 2048, when all communications are lost with the C.O.R.E. facility. The Special Technologies Unit, an elite unit of U.S. marines are sent in to investigate and re-establish contact. The player takes control of the marine Jason Crane. Crane fights his way through several levels when most of his fellow soldiers are killed or mutated, including his captain. In the main laboratories, Crane discovers ARG radiation, which is capable of speeding up chemical reactions or slowing them down to an "almost lack of existence." Once Crane reaches the command center, he encounters and kills Colonel R. Nightley. Nightley then sets off a self-destruct protocol and destroys the facility. Crane is able to escape into the service tunnels and makes his way to a cave system. At the end of the caves, he finds the meteor that crashed twenty years earlier. His weapons are absorbed by the meteor and Crane is teleported inside of it. The meteor turns out to be an alien ship. Several of the occupants come out of stasis and restore power to the ship. Crane however manages to destroy the ship's core and escape. After completion of the game an epilogue is viewed that shows that Crane is watching as the alien ship lifts out of the ground. It then shows that there are thousands of other ships emerging all over the world. The game ends on a note that, "and so the war begins," implying a possible sequel.

Multiplayer
The multiplayer game mode allows the players play as an orange, green, blue, or red teams. The game modes are team arena, team death match, capture the flag, and free for all.

Weapons
The game includes 8 different weapons: a pistol, shotgun, assault rifle, plasma rifle, beam rifle, shock rifle, rocket launcher, and an unspecified weapon. The game has jumping, full-scale 360 degree movement/view and alternate fire modes for some of the weapons.

Reception 
The game received generally negative reviews upon release and has a Metacritic score of 44/100 based on 16 reviews. Tom Mc Shea, writing for GameSpot, gave the game a 3.5/10 citing poor level design, controls, and combat.

HMS Snowdrop (1915). HMS Snowdrop was an  sloop  of the Royal Navy. She served during the First World War. Snowdrop survived the war and was sold for scrap in 1923.

Design and construction
The Azalea class was based on the previous , but with a heavier gun armament. They were designed at the start of the First World War as relatively fast minesweepers that could also carry out various miscellaneous duties in support of the fleet such as acting as dispatch vessels or carrying out towing operations, but as the war continued and the threat from German submarines grew, became increasingly involved in anti-submarine duties.

Snowdrop was  long overall and  between perpendiculars, with a beam of  and a draught of . Displacement was  normal. Two cylindrical boilers fed steam to a triple expansion steam engine rated at , giving a speed of .  The Azeleas had a main armament of two 4.7-inch (120 mm) or 4-inch (102 mm) guns, with two 3-pounder (47 mm) anti-aircraft guns also carried. Snowdrop had a crew of 90 officers and other ranks.

Snowdrop was ordered on 4 May 1915 from the Scottish shipbuilder Archibald McMillan & Son, and was built at their Dumbarton shipyard as Yard number 463. She was launched on 7 October 1915, and was completed on 3 December 1915.

Career
Snowdrop joined the 1st Sloop Flotilla, operating under the Vice Admiral Commanding, Coast of Ireland, following commissioning. In March 1916, Snowdrop was employed on escort duties. On 29 March, the sloop  was torpedoed by the German submarine , and Snowdrop and sister ship  were ordered to go to Begonias assistance. Begonia was towed to Queenstown (now Cobh). Following the outbreak of the Easter Rising against British rule in Ireland in April 1916, Snowdrop escorted a transport carrying troops to Galway on 30 April.

On 17 January 1917, Snowdrop and the sloop  were escorting the merchant ship SS Castalia when the German submarine  fired a torpedo which narrowly missed Myosotis. Myosotis opened fire on U-57 s conning tower and the submarine dived away to safety. On 5 April 1917, the merchant ship SS Canadian, which had been torpedoed by  the previous day, sank  west of Bantry Bay. Snowdrop rescued all but one of Canadians crew. On 23 April, the German submarine  attacked the steamer  with a torpedo and gunfire. The British submarine  drove off U-50 and later that day, Snowdrop took Dykland under tow at a speed of only , attempting to bring the damaged ship back to Bantry Bay. On 26 April, the tow parted, and the sloop  took over the towing duties, but Dykland finally sank later that day, still  short of safety. On 16 October 1917, Snowdrop took the American destroyer  in tow, after the Cassin had been torpedoed by  the previous day.

On 17 July 1918, she rescued the survivors from the liner , which had been torpedoed three times and sunk by  (six years earlier Carpathia had rescued the survivors from the ill-fated ).

Snowdrop survived the war and continued in service until being sold for breaking up on 15 January 1923 to the Unity Ship Breaking Company.

Ilyushin I-21. The Ilyushin I-21, (Istrebitel-21, fighter-21), also known as TsKB-32, was a single-engined, single-seat fighter produced in the USSR in 1936-7 in response to a government specification.

Design and development
The I-21 was an all-metal, low-wing, cantilever monoplane with retractable undercarriage and a closed cockpit. The wings were sharply tapered with straight trailing edges, which introduced sweepback on the leading edge. Two specially modified Mikulin AM-34RNF (also written AM-34FRN) liquid-cooled V-12 engines provided the power via a non-reducing gearbox, which was used only to raise the thrust line, and enable the use of shorter undercarriage legs.

Cooling for the first prototype's engine used an evaporative system which dispensed with radiators and used condensers built into the surface of the wing centre section.  The second prototype was fitted with a conventional cooling system using ethylene glycol coolant and a retractable radiator. Flight trials started but soon showed that the evaporative cooling system was inadequate with both the engine and the wing centre section overheating. Ilyushin was also very aware of the vulnerability of the system to combat damage, but he was ordered by GUAP to use this system. Further development was halted in 1939 and the I-21 designation was re-used for the Pashinin I-21.

Variants
