Imaduddin (activist). Imaduddin Abdulrahim (21 April 1931 – 2 August 2008), also known as Bang Imad, was an Indonesian religious and political activist and the spiritual head of the Indonesian Association of Muslim Intellectuals (ICMI). During 1960s and 1970s he served for 17 years as an electrical engineer by training at the Bandung Institute of Technology. In May 1978 Imaduddin was imprisoned for 14 months by the Suharto regime for his Islamic activism.

From 1979 he went to exile, got scholarship and studied industrial engineering in Iowa State University. After coming back to Indonesia at 1986 he moved to Jakarta, founded YAASIN (Yayasan Pembina Sari Insan) - the Foundation for the Development and Management of Human Resources  and Islamic TV programme.

In December 1990, he was permitted to organise ICMI under the patronage of the Indonesian vice-president, B. J. Habibie.

His conversation (interview) with V.S. Naipaul (Nobel Laureate 2001 - Literature) is the opening "story" of the book titled "Beyond Belief" 

Abdulrahim died on 2 August 2008, at the age of 77.

Sequence of events recorder. A sequence of events recorder (SER) is an intelligent standalone microprocessor based system, which monitors external inputs and records the time and sequence of the changes. They usually have an external time source such as a GPS or radio clock. When wired inputs change state, the time and state of each change is recorded.

SERs enable rapid root cause analysis after multiple events have occurred due to the secure recording of the sequence of events in the order of occurrence. SERs are therefore utilized as a diagnostic tool to minimize plant downtime. SERs are often interfaced with a SCADA system, distributed control system or programmable logic controller (PLC). 

SER reports are used by electrical engineers to analyze large and small electrical system blackouts. After the Northeast blackout of 2003, the North American Electric Reliability Corporation specified that electrical system data should be time-tagged to the nearest millisecond. 

In 1984, the Tetragenics Company, a subsidiary of the Montana Power Company, introduced the first remote terminal unit (RTU) that time-tagged events to the nearest millisecond, and now there are also other RTUs with this capability. Digital protective relays and some PLCs now also include time-tagging to the nearest millisecond; SCADA systems that incorporate these devices provide SER functions without a dedicated SER device.

121 Squadron, Republic of Singapore Air Force. The 121 Squadron "Brahminy Kite" ("Gannet" before 1994) of the Republic of Singapore Air Force (RSAF) currently operates the Fokker 50 Utility Aircraft (UTA) and Maritime Patrol Aircraft (MPA) based at Changi Airbase (West). The squadron goes by the motto of "Seek and Destroy" and the mascot is the brahminy kite.

History
Set up in 1973 with the commissioning of the SH 7 Skyvan 3M into the service of SADC. In 1993, the squadron found a new chapter to their successful career when they began operating the Fokker F50 MPA and UTL. With this move, the squadron's mascot was changed from the gannet to the brahminy kite, which is also reflected as the current centerpiece of the squadron's crest. As of September 2008, the Squadron has maintain an impressive safety record of over 124,000 accident-free flying hours, spanning a period of 35 years since the squadron's inception.

Roles and Missions
The primary role of the F-50 is to provide dedicated wide area maritime air surveillance for search and rescue operations, aeromedical evacuations and the transportation of personnel. The 121Sqn is unique in the RSAF, it is the first RSAF squadron to be crewed by both RSAF and RSN personnels as the pilots are drawn from the RSAF while the equipment/system specialists are from the RSN. As such, the F-50 MPA is part of a MINDEF system that comprises both Republic of Singapore Air Force and Republic of Singapore Navy assets that are capable of operations in tandem for seeking out and destroying a naval surface or sub-surface target, they can be quickly re-armed with the Harpoon Anti-ship missiles or EuroTorp A244/S ASW torpedoes as and when they are required to. The other squadron which integrate both Naval and Air operations are personnel from 123 Squadron with the Seahawks.

The squadron covers a wide spectrum of operations round the clock. These include Humanitarian Assistance and Disaster Relief (HADR) efforts such as Operations Flying Eagle in the aftermath of the Asian tsunami in December 2004, regular patrols of Singapore’s Sea Lines of Communication as well as participation in the Malacca Straits “Eyes-in-the-Sky” Joint Air Patrol with Indonesia and Malaysia.

SAF award
Also, the squadron has won the Best Tactical Support Squadron award (Singapore Armed Forces Best Unit Competition) for the fourth time in 2008; its past achievements being in 1997, 2002 and 2003.

Trench shoring. Trench shoring is the process of bracing the walls of a trench to prevent collapse and cave-ins.  The phrase can also be used as a noun to refer to the materials used in the process.

Several methods can be used to shore up a trench.  Hydraulic shoring is the use of hydraulic pistons that can be pumped outward until they press up against the trench walls.  This is typically combined with steel plate or a special heavy plywood called Finform.  Another method is called beam and plate, in which steel I-beams are driven into the ground and steel plates are slid in amongst them.  A similar method that uses wood planks is called soldier boarding.  Hydraulics tend to be faster and easier; the other methods tend to be used for longer term applications or larger excavations.

Shoring should not be confused with shielding by means of trench shields.  Shoring is designed to prevent collapse, whilst shielding is only designed to protect workers should collapse occur. Most professionals agree that shoring is the safer approach of the two.

Beaver River sandstone. Beaver River sandstone is a rock material locally found in northern Alberta, Canada, that was extensively used by First Nations people in prehistoric times to make tools with a sharp edge.  

Many projectile points and other tools made from the Beaver River sandstone have been found at archaeological sites in the Oil Sands region of Alberta. The source of this material has been identified as a site on the east side of the Muskeg River where native peoples quarried rock for use in making tools.

Jig (tool). A jig is a type of custom-made tool used to control the location and/or motion of parts or other tools.

Description

A jig's primary purpose is to provide repeatability, accuracy, and interchangeability in the manufacturing of products. 

An example of a jig is when a key is duplicated; the original is used as a jig so the new key can have the same path as the old one. Since the advent of automation and computer numerical controlled (CNC) machines, jigs are often not required because the tool path is digitally programmed and stored in memory. Jigs may be made for reforming plastics.

Jigs or templates have been known long before the industrial age. There are many types of jigs, and each one is custom-tailored to do a specific job.

Drill jig
A drill jig is a type of jig that expedites repetitive hole center location on multiple interchangeable parts by acting as a template to guide the twist drill or other boring device into the precise location of each intended hole center. In metalworking practice, typically a hardened drill bushing lines each hole on the jig plate to keep the tool from damaging the jig.

Drill jigs started falling into disuse with the invention of the jig borer.

Since the widespread penetration of the manufacturing industry by CNC machine tools, in which servo controls are capable of moving the tool to the correct location automatically, the need for drill jigs (and for the jobs of the drill press operators who used them) is much less than it used to be.

PCB jig

Printed circuit board (PCB) jigs are used to test PCBs. They have a dump board inside the jig which can find faults in the PCBs.

Jewelry jig
A jig used in making jewelry, a specific type of jig, is a plate or open frame for holding work and helping to shape jewelry components made out of wire or small sheets of metal. A jig in the jewelry making application is used to help establish a pattern for use in shaping the wire or sheets of metal. In the jewelry application, the shaping of the metal is done by hand or with simple hand tools like a hammer.

Daly detector. A Daly detector is a gas-phase ion detector that consists of a metal "doorknob", a scintillator (phosphor screen) and a photomultiplier. It was named after its inventor Norman Richard Daly. Daly detectors are typically used in mass spectrometers.

Principle of operation
Ions that hit the doorknob release secondary electrons. A high voltage (about ) between the doorknob and the scintillator accelerates the electrons onto the phosphor screen, where they are converted to photons. These photons are detected by the photomultiplier.

The advantage of the Daly detector is that the photomultiplier can be separated by a window, which lets the photons through from the high vacuum of the mass spectrometer, thus preventing an otherwise possible contamination and extending life span of the detector. The Daly detector also allows a higher acceleration after the field-free region of a time-of-flight mass spectrometer flight tube, which can improve the sensitivity for heavy ions.

Norman Richard Daly

Norman Daly was awarded 6 patents in the years 1962–1973 relating to ion detection and mass spectrometers, from his work at the United Kingdom Atomic Energy Authority.

Culver Dart. The Culver Dart was a 1930s American two-seat light monoplane aircraft produced by the Dart Aircraft Company (later the Culver Aircraft Company).

Design and development
In the early 1930s Al Mooney was working for the Lambert Aircraft Corporation, builders of the Monocoupe series aircraft. He designed a small two-seat monoplane, the Monosport G. When the company ran into financial difficulties Mooney bought the rights to his design and with K.K. Culver formed the Dart Aircraft Company. The aircraft was renamed the Dart Dart or Dart Model G.

The aircraft was a low-wing monoplane designed to be light with clean lines to enable it to use low powered aero-engines. It had a fixed undercarriage and a tailwheel. The initial version was named the Dart G powered by a 90 hp (67 kW) Lambert R-266 radial engine. That engine was in short supply, so the aircraft was fitted with a  Ken-Royce engine and designated the Dart GK. The final version was the Dart GW powered by a Warner Scarab Junior radial engine. Two special aircraft were built with larger engines. In 1939 the company was renamed the Culver Aircraft Company and the aircraft was renamed the Culver Dart.

HMS Elgin (J39). HMS Elgin was a Hunt-class minesweeper of the Aberdare sub-class built for the Royal Navy during World War I. She was not finished in time to participate in the First World War. A mine badly damaged her in 1944; she was sold for scrap in 1945.

Design and description
The Aberdare sub-class were enlarged versions of the original Hunt-class ships and carried more powerful armament. The ships displaced  at normal load. They had a length between perpendiculars of , and measured  long overall. The Aberdares had a beam of  and a draught of . The ships' complement consisted of 74 officers and ratings.

The ships had two vertical triple-expansion steam engines, each driving one shaft, using steam provided by two Yarrow boilers. The engines produced a total of  and gave a maximum speed of . They carried a maximum of  of coal which gave them a range of  at .

The Aberdare sub-class was armed with a quick-firing (QF)  gun forward of the bridge and a QF twelve-pounder (76.2 mm) anti-aircraft gun aft. Some ships were fitted with six- or three-pounder guns in lieu of the twelve-pounder.

Construction and career
HMS Elgin was built by the William Simons & Company at their shipyard in Renfrew. She was originally to be named Troon, but was renamed before launch to avoid possible misunderstandings of having vessels named after coastal locations. On 4 May 1944, Elgin was nine miles east of the Isle of Portland, when she triggered an acoustic mine that damaged her severely. She was towed to Portsmouth where she was scrapped in 1945.

Bellanca CH-400 Skyrocket. The Bellanca CH-400 Skyrocket is a six-seat utility aircraft built in the United States in the 1930s, a continuation of the design lineage that had started with the Bellanca WB-2. Retaining the same basic airframe of the preceding CH-200 and CH-300, the CH-400 was fitted with a more powerful Pratt & Whitney Wasp radial engine.

Three examples were purchased by the U.S. Navy under the designation RE. Two were used for radio research, and one as an air ambulance for the U.S. Marine Corps. This latter aircraft was reconfigured to carry two stretchers.

The aircraft was also available in a deluxe version for private pilot owners, fitted with a more powerful Wasp variant providing 450 hp (336 kW) and detail enhancements.

Two of these aircraft were purchased by the government of the Dominion of Newfoundland in 1937, and one later ended in private hands. NC10294 was changed to VO-BCD and NC13155 to VO-BDF.

Gorilla Project. The Gorilla Project refers to a former plan for construction of the first major oil refinery in the United States in over 30 years. In 2008, Hyperion Resources Inc., a Dallas-based energy company, had considered placing the ,  capacity refinery near Elk Point, South Dakota and approximately  away from Vermillion, among three other potential locations. Construction was originally intended to begin in 2008, but was progressively delayed.  The state construction permit expired on March 15, 2013.

The facility, which would process  of oil a day and use  of water daily from the Missouri River, caused significant controversy among concerned residents of Elk Point and the surrounding area. Prior to the announcement, the project and the company behind it were kept under considerable secrecy. It was known only as "Project Gorilla" while real estate agents made several purchase agreements on land north and east of Elk Point. Jeff Martin, a newspaper editor at the Argus Leader in Sioux Falls, uncovered two domain names, hyperionelkpoint.com and hyperionsd.com, which led to a news story that identified Hyperion for the first time. Elk Point is the forerunner among three other out-of-state locations Hyperion is considering for the refinery.

Opponents are concerned about air, water, and noise pollution; environmental degradation of nearby food crops such as soy beans, corn, and alfalfa; negative effects on the ethanol fuel market and competition with local ethanol-producing farmers; the displacement of thousands of local residents and negative population resettling; potential industrial disasters including explosions, leaks, and spills, reminiscent of the recent explosion at a similar-capacity Texas City Oil Refinery that caused the deaths of 15 workers and injured over 100; contamination and overuse of important water resources from the Missouri River; potential threats of terrorism; and concerns of the sheer size of the facility, which will be over twice the area of Elk Point.

In 2012 Hyperion allowed its development options on 5,000 acres of land in Union County to expire.  Infrastructure to supply the refinery did not exist, financing had become difficult, demand had fallen, and with the delay of the Keystone XL pipeline, the feedstock to the proposed refinery would not have been available.
