Kannagawa Hydropower Plant. The Kannagawa Hydropower Plant (神流川発電所) is an under construction pumped-storage hydroelectric power plant near Minamiaiki in Nagano Prefecture and Ueno in Gunma Prefecture, Japan. The power plant utilizes the Minamiaiki River along with an upper and lower reservoir created by two dams, the upper Minamiaiki Dam and the lower Ueno Dam. The power station in between the two dams will contain six  pump-generators for a total installed capacity of . Unit 1 commenced commercial operation in 2005 and Unit 2 in 2012. When completed, the plant will have the third-largest (after Fengning Pumped Storage Power Station and Bath County Pumped Storage Station) pumped-storage power capacity in the world.

Construction
In July 1993, the Kannagawa Hydropower Field Survey Office was initiated and in July 1995, the power plant was approved by the Electric Power Development Coordination Council. In May 1997, construction on the project began and by October 2003, the area behind the Ueno Dam was being inundated with water and the next year, the Minamiaiki Dam's reservoir began to fill as well. Both dams were completed and the upper reservoir was filled by 2004. The first generator was commissioned on 22 December 2005 and the second on 7 June 2012. The remaining units 3-6 are scheduled for commissioning by 2032.

Power station
The power station is  underground and measures  long,  wide, and  high. It will contain 6 x 470 MW pump generators for a total capacity of 2,820 MW. Water from the upper Minamiaiki Reservoir is transferred through the power house and after producing electricity, it runs to the lower Ueno Reservoir. The pump-generators can then pump water from the lower reservoir back up to the upper reservoir for re-use in hydroelectric power production. The water tunnel connecting the two reservoirs is  long. The power station also has an effective hydraulic head of  and maximum discharge of .

Dams
The Minamiaiki Dam is located in Nagano Prefecture and is a  high and  long rock-fill dam. It is made of  of material and withholds a  reservoir. The Ueno Dam, in Gunma Prefecture, is a  high and  long concrete-gravity dam. It is made of  of material and withholds a  reservoir.

SystemsGo. SystemsGo is a classroom program used in the United States promote the study of engineering and the development of work force skills. It is intended to encourage students to pursue careers in science, technology, engineering, and mechanics. It is based in Fredericksburg, Texas. It allows students to learn more about the past, present, and future of rocket technology, as well as use information learned from independent study to complete hands-on projects.

Annual Rocket Meet
Every spring, teams from high schools in the US gather in at several sites to launch their semester project rockets. The program offers high school students three different levels of projects, ranging from a mid-sized rocket traveling to a one mile apogee to rockets weighing several hundred pounds with the potential to reach near-space altitudes.

Program levels

Tsiolkovsky Level : The first stage of the Program, named after the Soviet rocket scientist Konstantin Tsiolkovsky, requires students to propel a research package to an altitude of 5,280 feet (one mile) and to recover it after launch.

Oberth Level : The intermediate stage, named after the German physicist Hermann Oberth, gives students the goal of designing and launching a rocket able to reach transonic velocity while maintaining a maximum altitude of less than 13,000 feet.

Goddard Level : The most advanced level, named after the American engineer and rocket scientist Robert H. Goddard, challenges students to create a rocket from scratch that can reach an altitude of 50,000 feet, which is considered to fall within the near space region of Earth’s atmosphere. Rockets for this level are often several hundred pounds and can reach velocities of Mach 3 or even Mach 4. Launches for this level are hosted by the US Army at the White Sands Missile Range, New Mexico.

Recognition
The SystemsGo program has been recognized and supported by such organizations as SpaceX, Dow Chemical, Boeing, NASA, and The Space Foundation.

Cray CX1000. The Cray CX1000 is a family of high-performance computers which is manufactured by Cray Inc., and consists of two individual groups of computer systems. The first group is intended for scale-up symmetric multiprocessing (SMP), and consists of the CX1000-SM and CX1000-SC nodes. The second group is meant for scale-out cluster computing, and consists of the CX1000 Blade Enclosure, and the CX1000-HN, CX1000-C and CX1000-G nodes.

The CX1000 line sits between Cray's entry-level CX-1 Personal Supercomputer range and Cray's high-end XT-series supercomputers.

CX1000 scale-up symmetric multiprocessing nodes 

The CX1000-SM and CX1000-SC nodes can be used for cluster computing, but they are designed for scale-up Symmetric Multi-Processing  (SMP). When used for cluster computing, the CX1000-SM node is intended to be the master (service) node, although it can instead be a compute node. Similarly, the CX1000-SC node, when used for cluster computing, is intended to be a compute node, but can instead act as the master (service) node. Either or both the CX1000-SC and/or CX1000-SM nodes can be deployed in a HPC cluster. The CX1000-SM and CX1000-SC nodes, when used for SMP, are connected by a cache-coherency interconnect which is a built-in subassembly of the CX1000-SM and CX1000-SC nodes, rather than a standalone device, and is called the Drawer Interconnect Switch in Cray literature. The Drawer Interconnect Switch uses the Intel QuickPath Interconnect technology.

CX1000 scale-out cluster computing nodes 

The CX1000 scale-out cluster computing group of systems consists of the CX1000 Blade Enclosure, CX1000-C compute Node, CX1000-G GPU Node and CX1000-HN Management Node. Unlike the CX1000-SM and CX1000-SC nodes, these nodes cannot be used for scale-up SMP, as they were designed without a cache-coherency capability. The CX1000-C and CX1000-G nodes both have blade form factors, and the CX1000-HN node is a rackmount 2U Server. The CX1000-HN is intended to act as the head (service) node in an HPC cluster, with CX1000-C and/or CX1000-G compute nodes.

Priestman Brothers. Priestman Brothers was an engineering company based in Kingston upon Hull, England that manufactured diggers, dredgers, cranes and other industrial machinery. In the later 1800s the company also produced the Priestman Oil Engine, an early design of oil fuelled internal combustion engine.

History

Priestman family ownership (1870–1895)
The company was founded in 1870; William Dent Priestman bought the Holderness Foundry with money from his father, a Leeds corn-miller. William's brother Samuel also joined the company.

It is said the company's entry into the construction of dredging equipment began in 1876 when they were asked to construct machinery to recover lost gold from the sea west of the coast of Spain. No gold was found but the company's equipment proved useful for dredging of harbours and docks; the company pioneered the manufacture of steam powered cranes with grab (clamshell) buckets.

From 1888 to 1904 the company produced various versions of the Priestman Oil Engine, an early example of an internal combustion engine. Models were produced with engine power from  up to  for a double cylindered version. The company opened a factory in Philadelphia (USA) in 1892, also producing engines. In 1894 the company produced one of the earliest recorded examples of an internal combustion engine for railway, based on an 1888 prototype – the 20 h.p. two axle machine was tested on the Hull Docks.

In 1895 bad debts and a decline in sales made the company insolvent, the business was reformed but William and Samuel lost their seats on the board.

Public ownership (1895–)

The company was reformed and began business again; after the First World War its products were used in the rebuilding of French villages, in 1921 a machine for digging field drainage drains was produced and the company received investment from the Ministry of Agriculture.

The company constructed a factory in Marfleet, Hull in 1950, which eventually covered .

In 1928 production of excavators named after animals began; models named "Lion", "Tiger" and "Panther" were produced.

The company merged with Coles Cranes of Sunderland in 1970.

In 1972 the Steels Group, Priestman's parent company, was taken over by the Acrow Group.

The Priestman division was sold off in 1984 and was eventually merged with Coles Cranes. The remnants of the company are owned by Gardner Denver, and it no longer supports the Priestman range of products.

The Priestman Grab & VC Excavators Divisions were sold to RB International, this business continues to be supported by Delden Cranes Ltd, through their RB Cranes Division.

William C. Davis Jr.. William C. Davis Jr. (1921–2010) was an American ballistics engineer, best remembered as a writer and editor on ballistics for American Rifleman magazine.

Early life
After graduating from Shinglehouse High School in 1937, Davis received a degree in physics and mathematics from Saint Bonaventure University in 1941.  He joined the United States Army in 1942, was a qualified expert with rifle, pistol, and carbine, and served through World War II advancing to the rank of captain.

Engineer
He became a civilian ordnance engineer in 1951, and worked at Aberdeen Proving Grounds, Frankford Arsenal, and Rock Island Arsenal.  He was the United States representative for the Perdine trials of 1953 leading to the adoption of the 7.62×51mm as the standard NATO military cartridge.  He subsequently assisted the development of the 5.56×45mm cartridge and M16 rifle before retiring from federal employment in 1972.  Davis founded Tioga Engineering Company in 1980.

Author
Davis' first article for the American Rifleman was published in 1949.  He became a contributing editor to the publication in 1974 and was named ballistics editor in 1986.  He wrote the "Ammunition" section of Encyclopædia Britannica and published 14 computer ballistics programs.

Scandium monosulfide. Scandium monosulfide is a chemical compound of scandium and sulfur with the chemical formula ScS. Although its formula might suggest that it is a compound of scandium(II), i.e. [Sc2+][S2−], ScS is probably more realistically described as a pseudo-ionic compound, containing [Sc3+][S2−], with the remaining electron occupying the conduction band of the solid.

Structure
Scandium monosulfide adopts the sodium chloride crystal structure type.

Synthesis
Scandium monosulfide can be prepared by heating a mixture of scandium metal and powdered sulfur in the absence of air to 1150 °C for 70 hours.

Sc + S → ScS

Alliance P.2 Seabird. 

The Alliance P.2 Seabird was a British single-engined long-range biplane designed by J.A. Peters to enter the Daily Mail £10,000 Atlantic Flight Prize. In the end it did not compete but became the first aircraft to fly from London (Acton) to Madrid non-stop on 31 July 1919.

Design and development
The  Alliance Aeroplane Company which had constructed aircraft under licence during the First World War decided to build aircraft for the civil market. The Seabird was a long-range two-seat biplane powered by a  Napier Lion piston engine. With an endurance of 21 hours it had an enclosed cabin for the crew of two and two aircraft were built.

Operational history
On 17 April 1919 Peters the designer paid the £100 entrance fee to the Royal Aero Club as entry fee for the Alliance biplane into the competition for the Daily Mail £10,000 Atlantic Flight Prize. Flown by Peters with Captain W.R. Curtis of the Royal Air Force the first Seabird (registration G-EAGL) carried out a trial flight on 31 July 1919 when it made the first direct non-stop flight between London and Madrid, 900 miles in just under eight hours. The aircraft did not in the end compete in the Atlantic competition.

The second aircraft G-EAOX was entered into an Australian Government prize of £10,000 for a flight from Great Britain to Australia.  Flown by two Australian airmen, Lieutenant Roger Douglas (pilot) and Lieutenant J.S.L. Ross (Navigator), G-EAOX left Hounslow Heath Aerodrome on 13 November 1919 but a few minutes into the flight the Seabird crashed near Surbiton killing both airmen.

The company never recovered from the accident and was closed down in 1920.

Speedy-class brig. The Speedy class brigs were a two-ship class of brig built for the Royal Navy during the later years of the American War of Independence. They survived into the French Revolutionary Wars.

Concept
The Speedy class was designed in 1781 by the shipbuilder Thomas King, of Dover, a specialist builder of such craft. They were designed with a cutter-type hull, and anticipated the development of a new concept of the brig in naval warfare, that of small, fast escort vessels, instead of the slower but more seaworthy ship-sloops. Their names were selected to epitomise this approach, , and . Small, light craft, they were 207  Tons bm, and measured  (overall) and  (keel), with a beam of  and  depth in the hold. Armed with fourteen 4-pounders, giving a broadside weight of 28 pounds, and twelve -pdr swivel guns, they had a crew of 70. This was broken up into 57 officers, seamen and marines; 12 servants and boys; and 1 widow's man.

Careers
Both ships were completed too late to see any significant service in the American War of Independence, and spent most of the years of peace in British waters. Flirt sailed to the Caribbean in 1791, but was laid up in Deptford in November 1792, and did not return to service before being sold in 1795. Speedy was still in service on the outbreak of war with revolutionary France and was assigned to the Mediterranean, where she served under a number of distinguished commanders. She was captured in 1794, but had been retaken within a year. Her last captain, Lord Cochrane, achieved some of his greatest exploits with her, forcing the surrender of a much larger Spanish warship, the Gamo, but was forced to surrender her after being pursued by a large French squadron in 1801. She was donated to the Papal Navy by Napoleon and broken up a few years later.
