Xi'an H-8. The Xian H-8 bomber () was a Chinese military aircraft and a possible successor to the aging twin-engined Xian H-6 jet bomber. It is referred to as Xian H-7 in some sources. The proposed designs were reported to be an enlarged H-6 with four or six underwing engines, but the project was canceled in 1971 in early development stage.

Development
On 23 March 1970 the No.603 Research Institute was tasked with developing a strategic bomber to be designated H-8, to reduce costs and development time the Xian H-6 airframe was used as a baseline. The first working sample was expected to be completed in 1973, and production was expected to be as early as in 1974.

However, the development of the H-8 paced slowly and came to a halt as major development resource was transferred to Shanghai Y-10. In September 1971, the H-8 project was canceled, whilst the H-6I was continued on as a substitute.

Variants
Xian H-8I – Two powerplant options were studied, using four WS-6J (Type 910) turbofans or six Pratt & Whitney JT-3D turbofans but no aircraft were built.
Xian H-8II – A H-6 with increased wing span, powered by six WS-6J turbofans in evenly spaced nacelles, and possibly a re-designed flight-deck with an extended solid nose. No aircraft were built.

Glasgow Bridge, Glasgow. The Glasgow Bridge spans the River Clyde in Glasgow linking the city centre to Laurieston, Tradeston and Gorbals.  Formerly known as Broomielaw Bridge, it is  at the bottom of Jamaica Street near Central Station, and is colloquially known as the Jamaica Bridge.

The original bridge was completed in 1772, and was designed by William Mylne and built by civil engineer John Smeaton. Its seven-arch structure was honoured by Thomas Telford, the first president of the Institution of Civil Engineers, who replaced it in 1833 with a design built by John Gibb & Son for £34,000.   One of Telford's colleagues,  Charles Atherton, was the resident engineer for the Works.  It became the first in Glasgow to be lit by electricity. Between 1895 and 1899 it was replaced with the current wider bridge which incorporated Telford's stonework and expanded the arches to accommodate larger ships. The present structure is protected as a category B listed building.

Proposed bridge
The Glasgow Bridge was also the name of a proposed bridge. Designed by the Richard Rogers Partnership, it was to be a curved, ramped deck bridge, using a cable stayed compression arch to provide an additional route from Broomielaw to Tradeston. However, late in 2006 funding was withdrawn for this project. The Tradeston Bridge has since been built to serve this function.

Electrical outlet tester. An electrical outlet tester, receptacle tester, or socket tester is a small device containing a 3-prong power plug and three indicator lights, used for quickly detecting some types of incorrectly-wired electrical wall outlets or campsite supplies.

Tests and limitations

The outlet tester checks that each contact in the outlet appears to be connected to the correct wire in the building's electrical wiring. It can identify several common wiring errors, including swapped phase and neutral, and failure to connect ground. 

The tester confirms continuity and polarity of the electrical connections, but it does not verify current-carrying ability, electrical safety (which requires impedance testing), insulation breakdown voltage, or loop connection of ring mains.

Simple three-light testers cannot detect some potentially serious house wiring errors, including neutral and ground interchanged at the receptacle. There may be a "bootleg ground", where the neutral and ground pins have been connected together at the receptacle, which cannot be detected either. These problems can be detected with a multimeter and a test load, to verify that the ground connection is separate from the neutral and is not carrying normal circuit return current, or more typically by using a more-sophisticated multifunction tester. 

A quick supplemental screening test for these simple miswiring errors can be performed using a non-contact voltage tester (NCVT) or non-contact voltage detector. If a problem is thus identified, it can be investigated further using more-advanced equipment, or the outlet in question can be de-energized and disassembled for careful scrutiny.

Some receptacle testers include an additional test button to test the triggering of GFCI devices, which supplements the built-in test button on the GFCI and can be used for testing outlets downstream from a GFCI receptacle. "Plug-in analyzers" may include earth loop impedance and other checks.

History
An early reference that describes the typical outlet tester circuit was published in Popular Mechanics in the March issue of 1967, and consists of two 27 kΩ resistors, one 100 kΩ resistor, and three NE-51 neon lamp bulbs with 100 kΩ resistors.

Xiaowan Dam. The Xiaowan Dam () is an arch dam on the Lancang (Mekong) River in Nanjian County, Yunnan Province in southwest China. The primary purpose of the dam is hydroelectric power generation and it supports a 4,200 MW power station. Constructed between 2002 and 2010 by Huaneng Power International at a cost of ¥32 billion (nearly US$3.9 billion), it is the world's second highest arch dam at . It is also third highest among dams of all types behind Jinping-I and Nurek and the third largest hydroelectric power station in China.

Background
The feasibility study for the dam was completed in 1992, with it as part of the Lancang River Project. In 1995 the report was reviewed and approved by the Chinese government. Three years later in 1998, a consortium to fund and construct the dam was organized. In 1999, preliminary construction (roads, bridges, river diversion) began. Official construction on the dam started on 1 January 2002. The river was diverted by November 2003 and concrete pouring began in 2005. The river diversion was closed and the reservoir began to impound in November 2007. The first generator was commissioned in September 2009 and the dam was complete in March 2010. The last of the six generators went operational on 22 August 2010. The creation of the dam's reservoir submerged  of land and displaced 32,737 people.

Montgomery C. Meigs Jr.. Montgomery Cunningham "Monty" Meigs Jr. (February 27, 1847 – December 9, 1931) was an American civil engineer.

Background
The son of U.S. Army General Montgomery C. Meigs, he was born in Detroit, Michigan, and educated at Harvard University and in Germany. He worked for a few years for the Northern Pacific Railroad, before taking the post of a civil engineer in Keokuk, Iowa, in 1882.

Civil career
The junior Meigs is best known for his management of the canal and locks at the Des Moines Rapids, as well his involvement in the construction of the dam at the same which inundated the canal.

Although Meigs had not served in the military, he was often referred to as "Major" out of courtesy, because his predecessor at the Des Moines Rapids had been an army officer. Meigs' design for traffic control at the canal and locks prompted Captain F.A. Whitney to tell the Saturday Evening Post in 1924 that he could not recall a single incident having occurred by any vessel passing through the locks, so long as the rules had been obeyed, and that Meigs did not hesitate to become involved personally if needs be.

Other interests and skills
Meigs was an accomplished riverboat pilot. One of his six daughters, author Cornelia Meigs, wrote in the Keokuk Daily Gate newspaper, dated July 30, 1966:
"...It is an unrecorded part of my father’s work that he had the whole picture of the river channel so fully in his mind, with his almost day to day information as to what the mighty Mississippi was about that he felt himself able, where other men would be in doubt, to take the wheel of the big passenger and cargo boats, carrying several hundred people, and pilot them himself down through some treacherous reach of the channel, often rising from his bed at night to do so. He was accepted as a welcome aide by the regular pilots who must know the long stretches of the river but could sometimes not be quite sure in the particularly difficult and rapidly changing channel."

Besides fulfilling this position for the government, Meigs was an inventor.  He invented a "canvas coffer-dam," and pioneered the application of crude oil to dirt roads to improve driving conditions by controlling dust and mud.

He also built and designed steamboats and steam dredge tenders. From 1910 to 1913 he was the local inspecting engineer in the construction of the great lock, dry dock, and power developments on the Mississippi at Keokuk.

Personal life
Meigs and his wife Grace Lynde had six daughters: Mary Meigs Atwater, Louisa Meigs Green, the physician Grace Meigs Crowder, Alice Meigs Orr, writer Cornelia Lynde Meigs, and Emily Meigs Fales.
