Data Loading and Analysis System. The Data Loading and Analysis System (DaLAS) is an electronic database used by the Federal Bureau of Investigation and United States Intelligence Community for counterintelligence and counterterrorism investigations. It is used to store copies of seized digital media, including disk images of CD-ROMs, DVDs, hard drives, mobile phones, and raw network feeds, as well as scans of physical documents. DaLAS supports the upload, processing, and classification of media, and provides a central, remotely accessed, searchable repository of data. The full details of DaLAS, including the number of files and total amount of stored data, are classified.

During a 2011 investigation in the aftermath of the 2009 Fort Hood shooting, a query of Nidal Malik Hasan's personal email account returned a result on a hard drive image stored on DaLAS. The drive had been seized in 2007 in an unrelated New Jersey tax case. The match was a message posted to a web forum by Hasan on February 10, 2005, asking whether doctors should prescribe intoxicating medications under Sharia law.

Bauernfeind prism. A Bauernfeind prism is a type of reflecting prism used to deviate a beam of light by 45° to 60°, depending on its construction, while neither flipping nor rotating the image. It is named for its inventor, the German expert of geodesy Karl Maximilian von Bauernfeind.

The beam is reflected twice in the prism, with one reflection happening at less than the critical angle.  Therefore, the prism requires a reflective coating for this surface to be usable in practice.

A Bauernfeind prism with 45° beam deviation is also known as a half-penta prism or semipentaprism. A Bauernfeind prism is used together with a Schmidt roof prism to form a Schmidt–Pechan prism.

Applications 
The Bauernfeind prism is commonly used in microscope tubes and in geodesy to deviate the path to the eyepiece in order make the device more ergonomic.

More recent applications are glasses that deflect the viewing angle either downwards (for relaxed reading or watching TV), or upwards (as in belay glasses for watching a climber while belaying).

Manganvesuvianite. Manganvesuvianite is a rare mineral with formula . The mineral is red to nearly black in color. Discovered in South Africa and described in 2002, it was so named for the prevalence of manganese in its composition and its relation to vesuvianite.

Occurrence and formation
Manganvesuvianite crystals occur as long prisms up to . Small crystals are transparent and red to lilac in color; large crystals are opaque and nearly black in color with dark-red internal reflections. Strongly zoned crystals less than  in size constitute rock-forming manganvesuvianite.

, manganvesuvianite has been found at two locations in South Africa. It formed at temperatures of  by the hydrothermal alteration of sedimentary and metamorphic manganese ores. Crystallization occurred in fault planes and lenticular bodies in the ore bed or by filling veins and vugs. Manganvesuvianite has been found in association with calcite, manganese-poor grossular, hydrogrossular-henritermierite, mozartite, serandite-pectolite, strontiopiemontite-tweddillite, and xonotlite.

Manganvesuvianite is a member of the vesuvianite group and is the manganese analogue of vesuvianite.

History
In 1883, Arnold von Lasaulx made the first detailed description of vesuvianite containing up to 3.2 wt% MnO from Lower Silesia in Poland. Studies in the 1980s and 1990s revealed that the vesuvianite group was more complex than previously assumed, necessitating the definition of new minerals. In 2000, vesuvianite was found containing up to 14.3 wt% MnO from the Kalahari manganese fields of Northern Cape Province, South Africa. Manganvesuvianite proper was discovered in the Wessels () and N'Chwaning (shaft II; ) mines of the Kalahari manganese fields and described in 2002 in the journal Mineralogical Magazine. It was named manganvesuvianite for the significant manganese in its formula and its relation to vesuvianite. The mineral and name were approved by the IMA Commission on New Minerals and Mineral Names (IMA 2000-40). The type specimen from the N'Chwaning II Mine is held at the Natural History Museum of Bern in Switzerland.

6th Engineer Support Regiment (Australia). The 6th Engineer Support Regiment (6 ESR) is a specialised engineer regiment of the Australian Army. Established in early 2003, the regiment was formed by grouping several previously independent engineer squadrons – each providing different engineer support functions – together under a single headquarters. Headquartered at RAAF Base Amberley in Queensland, the regiment's sub-units are also based in Queensland.

History
The regiment was formed on 13 January 2003, in order to serve as the administrative headquarters for a number of squadron-level subunits, which had previously been independent.

Attached to the 6th Brigade, the regiment's subunits – the 17th and 21st Construction Squadrons, the 1st Topographical Survey Squadron and the 20th Explosive Ordnance Disposal Squadron – were spread across three different locations: Gallipoli Barracks in Enoggera; RAAF Base Amberley in Amberley; and Holsworthy Barracks in Holsworthy. These subunits are supported by a fifth subunit, the Operational Support Squadron.

By virtue of the regiment's function, the majority of its 600 personnel are regular soldiers drawn from the Royal Australian Engineers, although various other corps provide administration clerks, drivers, mechanics and quartermasters. Personnel from the regiment have undertaken numerous deployments since its establishment, and the regiment provided the headquarters element for Reconstruction Task Force 4, which deployed to Afghanistan in 2008 as part of Operation Slipper.

The 1st Topographical Survey Squadron was reassigned to the 1st Intelligence Battalion. The 17th Construction Squadron relocated to RAAF Base Amberley in Queensland from Holsworthy Barracks in New South Wales.

When the 6th Brigade was disbanded in December 2014 the 6th Engineer Support Regiment was transferred to the 17th Sustainment Brigade.

Structure
The regiment consists of the following units:

Amberley
Regimental Headquarters
17th Construction Squadron
21st Construction Squadron
Operational Support Squadron
20th Explosive Ordnance Disposal Squadron

Kylesku Bridge. The Kylesku Bridge (officially known since 2019 by its Gaelic name Drochaid a' Chaolais Chumhaing) is a distinctively curved concrete box girder bridge in north-west Scotland that crosses Caolas Cumhann (Gaelic for "narrow strait", pronounced "Kyles Cuan"); the channel that connects Loch Glencoul and Loch Glendhu with Loch a' Chàirn Bhàin in Sutherland. It is listed as category A, the highest grade.

History
In June 1978, the Highland Regional Council asked Ove Arup & Partners Scotland to prepare a feasibility study for a bridge, in their capacity as consulting civil engineers, and it was prepared by March 1979.

Construction for the approach roads, costing £4 million, began in summer 1981. Construction of the bridge began in August 1982, with Morrison Construction and Lehane, Mackenzie and Shand the chief contractors.

It was constructed by building out the supporting legs and then lifting into place the central span, which weighed .

The cost of the bridge was £4 million, although was earlier budgeted at £2.75 million. The bridge opened to traffic in July 1984, and was formally opened by the Queen on 8 August 1984.

In 2019, the bridge was classified by Historic Environment Scotland as a Category A structure, recognising it as "visually striking and technically innovative". It was also officially renamed to the Gaelic translation of its name, Drochaid a' Chaolais Chumhaing.

Geography
The bridge crosses water which is approximately  wide and up to  deep, leading to fast tidal currents. It replaced the ferry between Kylesku and Kylestrome, which was approximately  to the east.

Design
The bridge is  long with a  long main span. The bridge deck is at a height of  above high water to provide navigation for ships.

The bridge deck is supported by V-shaped inclined piers, with eight inclined legs, in order to reduce the length of the main span. The lateral forces from each leg balance, so the total force on the foundations is vertically downwards. The spread of legs supports the bridge in winds which can exceed , and also loads resulting from the curvature of the bridge. There is no joint between the legs and the deck of the bridge, with the expansion joints and bearings being located at the abutments to facilitate straightforward maintenance. The legs are formed from reinforced concrete and the deck from prestressed concrete using cables tensioned at up to 52,200 kN.

The bridge is designed to be sympathetic to the surrounding country, and the approaches were chosen to minimise changes to the landscape.

Verville-Packard R-1. The Verville-Packard R-1 was a military racing aircraft that was modified from Alfred V. Verville's previous Verville VCP-1 design.  The R-1 is sometimes known also as the Verville-Packard VCP-R or the Verville-Packard 600.  The R-1 was the first racing aircraft built for the United States Army Air Corps.

Development
The first R-1 was created from a VCP-1 in 1919, by installing the Packard V-12 engine.

Operational history
On November 27, 1920, Capt. Corliss Moseley, flying an R-1 racer, out of 24 track finishers, won the Pulitzer Trophy Race at Mitchel Air Force Base.  The top speed was 156.54 mph.

It also raced in the 1920 Gordon Bennet Trophy air race.

Artifact Puzzles. Artifact Puzzles is a manufacturer of wooden jigsaw puzzles operating out of Port Townsend, Washington (previously in Fremont, California). The business was founded in 2009 by University of Washington electrical engineering professor Maya Gupta, and was originally based in Seattle, Washington. Unlike traditional wooden jigsaw puzzles which are hand-cut by jigsaw, Artifact Puzzles laser-cuts 1/4" thick high quality 3-ply environmentally-friendly plywood and uses soy-based inks.

The puzzle pieces are designed by an artist for each new puzzle, and do not follow a consistent style of cut. For example, some of their puzzles have traditional knob connectors, while others have piece connectors shape like clouds, hearts, bird feet, horse hooves, and ancient Greek symbols. Like traditional wooden jigsaw puzzles, most of their puzzles have "whimsy pieces", which are pieces shaped like recognizable objects. These pieces are designed to match the theme of each puzzle, and range from a cow jumping over a moon in one of their Daniel Merriam puzzles, to pieces shaped like ballerinas in their Degas puzzle. The company has designed and manufactures over 250 different puzzles of a broad range of art, with an unusually large selection of whimsical neo-surrealist art and 16th century art.

Steel Heddle Manufacturing Company Complex. The Steel Heddle Manufacturing Company Complex is an historic, American factory complex that is located in the Allegheny West neighborhood of Philadelphia, Pennsylvania, United States.

It was added to the National Register of Historic Places in 2010.

History and architectural features
This historic complex consists of four buildings: the plant (1919, 1925–1927), the main office (c. 1919–1922), the chrome plating building (1951), and the lumber storage and garage building (1930). The plant is a five-story, U-shaped, reinforced concrete building that sits on a raised basement.

The Steel Heddle Manufacturing Company manufactured heddles and other textile loom accessories. Its Philadelphia plant remained in operation until 1983.

This complex was added to the National Register of Historic Places in 2010. In 2018, NBC10 erroneously reported that the complex was destroyed by fire, but the buildings that burned were a block away and unrelated to Steel Heddle. The vacant Steel Heddle plant still stands in 2019.

WAGR B class (diesel). The B class were a class of diesel locomotives built by Commonwealth Engineering for the Western Australian Government Railways between 1962 and 1965.

History
The first five B class units entered service in 1962. Three years later, a second batch of five was delivered.

The second batch differed from the first only in having sloping cab sides, to enable the second batch to pass underneath the limited clearance cranes on the Fremantle wharves.

All members of the class spent the whole of their working lives in the Perth metropolitan area, and were written off as a group in September 1984. Some of them have since been preserved.

Reaktor Serba Guna G.A. Siwabessy. Reaktor Serba Guna–Gerrit Augustinus Siwabessy (RSG-GAS) (Multipurpose Reactor–Gerrit Augustinus Siwabessy) is a research reactor located in the Serpong neighborhood of South Tangerang, Banten, Indonesia. The reactor plays an important role in the Centre for Nuclear Industry Development, at Puspiptek, Serpong to serve other supporting laboratories, namely, radioisotope production, nuclear material science, reactor fuel element development, reactor safety, waste treatment, radio-metallurgy and nuclear-mechano laboratories.

The reactor was constructed through a $50 million contract with Interatom Internationale Atomreaktorbau GmbH, a unit of the West German steelmaker Kraftwerke Union, which was awarded in 1981. The reactor's fuel rods have originated in the United States, France and the United Kingdom; the fuel was enriched in the United States and Russia. The International Atomic Energy Agency safeguards the reactor. It was inaugurated by the second President of Indonesia, Suharto on August 20, 1987. The reactor was named after G.A. Siwabessy, Minister of Health and Minister of Atomic Energy under both president Sukarno and Suharto.

RSG-GAS went to its first criticality on July 29, 1987. The nominal power of 30 MW thermal was achieved on March 23, 1992, at the sixth core containing 40 standard fuel elements and 8 control fuel elements.

Air France Flight 406. Air France Flight 406 was a Lockheed L-1649 Starliner that crashed in French Algeria on May 10, 1961, after a bomb exploded on board. All 78 passengers and crew on board were killed. It was the deadliest aviation disaster involving a Lockheed Starliner.

Flight
Air France Flight 406 was an international scheduled passenger flight originating in Brazzaville, Congo, on a route with the final destination Paris, France. Intermediate stops were Fort Lamy, Chad, and Marseille, France. The flight was flown by a Lockheed L-1649 Starliner, F-BHBM De Grasse.

After taking off from Fort Lamy, and while cruising at an altitude of approximately , the Starliner broke up after its empennage failed. The plane crashed to earth approximately  from Edjele oilfield, near the Libya border. All aboard Flight 406 were killed.

Eighteen children were among the dead. Among them were the three young children of the United States Charge d'Affaires in the Central African Republic, who, along with their mother (the charge's wife), were on Flight 406 headed for London. Also among the dead were a count and countess, plus two Central African Republic government ministers. Rumors began to surface after Flight 406's crash that it had been an assassination by enemies of the Central African Republic.

Investigation
The most probable cause of Air France Flight 406 crashing was sabotage with a nitrocellulose explosive.
