Queensland Railways 1250 class. The 1250 class were a class of diesel locomotive built by English Electric, Rocklea for Queensland Railways between 1959 and 1963.

History

The design of the 1250 class was unusual being a cab unit with a cab similar to the 1200 class but with a narrow long hood. They were based on a design built for use in Brazil five years prior. A derivative was also built for Rhodesia Railways in 1962.

The first five units had a  engine and screw couplers.

The subsequent units fitted with a  engine, auto couplers and were wired for multiple unit operation.

They were used on ore traffic on the Great Northern line, and on general freight on the North Coast and Southern lines. A characteristic addition to the 1250 class in 1961 was a sun visor to help reduce glare.

Withdrawal & disposal
Two were withdrawn in the early 1980s, donating parts to the rebuild of the single 1225 class locomotive. The remainder were withdrawn in 1987. Two units have been preserved:
1262 was retained by the Queensland Rail Heritage Division and is on static display as a cutaway at the Workshops Rail Museum, North Ipswich
1263 is owned by the Australian Railway Historical Society and stored in Townsville

Bolon (flooring company). Bolon is a Swedish design company based in Ulricehamn, Sweden. Bolon is known for inventing the woven vinyl flooring. The company was founded by Nils-Erik Eklund back in 1949.

History
Bolon was founded by Nils-Erik Eklund in Stockholm 1949. Eklund began to use textile waste to manufacture woven rag rugs from a nearby factory. Later on in the 1960s Nils-Erik's son Lars and his wife Monica took over and continued developing the concept of the rag rug and also began to awn mats for caravans.

In 2003 the third generation of the family, the sisters Marie and Annica Eklund, took over the enterprise. With the sisters running the company Bolon repositioned themselves as a global design brand with projects all over the world including Australia, China, Japan, Italy, the UK and the US . Its clients include brands such as Google, Mercedes and Armani. During the last couple of years Bolon have collaborated with several designers and architects such as Missoni and Jean Nouvel

In 2011 Bolon won the Elle Decoration International Design Awards for their Botanic collection. Marie and Annica Eklund were awarded with "Näringslivsmedaljen"  from The Royal Patriotic Society, Kungliga Patriotiska Sällskapet in 2015.

Other
The company's name is a combination of the first and last letters of the Swedish words for cotton (bomull) and nylon.

Percy White (nuclear scientist). Percival Albert Frederick White OBE (16 July 1916 – 8 January 2013) was a British chemist, metallurgist and nuclear scientist who was involved in the creation and testing of Britain's first nuclear weapon during Operation Hurricane in 1952. He also made significant contributions to the advancement of explosives manufacturing, chemical engineering and civilian nuclear technology, and authored numerous books on engineering.

Early life and education
White was born in London in 1916 and moved to South Wales at an early age. He studied chemistry at University College, Swansea, graduating in 1936 at the age of 19 with first-class honours. He went on to study chemical engineering at University College London, and then began a career in industrial metallurgy.

Second World War
During the Second World War, White worked for the British government as a specialist in ammunition and chemical warfare. While working for the Royal Ordnance Factories, he patented a method of efficiently manufacturing high explosive shells. After the war, White worked in military research at the Defence Research Establishments at Waltham Abbey and Porton Down, before moving to the Woolwich Arsenal.

Nuclear weapons research and later career

In 1949, White joined the secret High Explosives Research (HER) project, which was tasked by Lord William Penney with producing Britain's first nuclear bomb. In 1950, HER was moved to Aldermaston, where White served as the chief chemical engineer and helped create a crucial radioactive liquid treatment plant. The HER project culminated in the successful Operation Hurricane, Britain's first nuclear test, on 3 October 1952.

Thereafter, White continued to work in nuclear science, collaborating with American researchers and contributing to the development of the Dounreay civilian nuclear reactor. He was appointed OBE in 1966, and retired in 1972, though he continued to advise the British government and private companies on the use of chemical engineering and nuclear technology. He also authored a number of books on chemical engineering and air filtration.

Personal life
White married Jean Bracey in 1940; they had two children, and remained married until her death in 2007. At the time of White's death in 2013, he had two children, four grandchildren and six great-grandchildren. White was a keen amateur artist, training as an enameller at Southampton College of Art in his retirement, and exhibiting his artworks in London and Winchester.

Energy-dispersive X-ray diffraction. Energy-dispersive X-ray diffraction (EDXRD) is an analytical technique for characterizing materials. It differs from conventional X-ray diffraction by using polychromatic photons as the source and is usually operated at a fixed angle. With no need for a goniometer, EDXRD is able to collect full diffraction patterns very quickly. EDXRD is almost exclusively used with synchrotron radiation which allows for measurement within real engineering materials.

History 
EDXRD was originally proposed independently by Buras et al. and Giessen and Gordon in 1968.

Advantages 
The advantages of EDXRD are (1) it uses a fixed scattering angle, (2) it works directly in reciprocal space, (3) fast collection time, and (4) parallel data collection. The fixed scattering angle geometry makes EDXRD especially suitable for in situ studies in special environments (e.g. under very low or high temperatures and pressures). When the EDXRD method is used, only one entrance and one exit window are needed. The fixed scattering angle also allows for measurement of the diffraction vector directly. This allows for high-accuracy measurement of lattice parameters. It allows for rapid structure analysis and the ability to study materials that are unstable and only exist for short periods of time. Because the whole spectrum of diffracted radiation is obtained simultaneously, it enables parallel data collection studies where structural changes can be determined over time.

The Triplets bridges. Three consecutive Extradosed bridges are part of a north beltway of La Paz in Bolivia.

The project was funded by CAF (Corporación Andina de Fomento) through a credit to the Municipality in 2006. In 2007, the Municipal Government of La Paz awarded the design and construction of The Triplets Bridge Project to the JV “Consorcio Asociación Accidental Progreso”. As part of this contract, PEDELTA carried out the conceptual and final detailed design.

There was a preliminary design that defined three three-span cable-stayed bridges with central spans between  and two cable-stay planes, similar to another existing in the city: the Bridge of the Americas. After a study of alternatives, where the bridge should have a cable supported deck in order to fulfill the technical specifications of the contract, it was proposed to modify the structural type to improve the visual impact on the landscape of La Paz. Therefore, it was proposed an extradosed bridge type, which reduces the height of the pylon, and a single plane of stays to allow a more transparent view

Description
The Triplets have similar structural pattern and basic idea, but the dimensions are different. All bridges are extradosed with a three-span deck and single central plane of stays.

The bridge deck is  wide and carries four vehicular lanes, two lateral sidewalks  wide, and a central median of  where stays anchor, protected on each side by a rigid concrete barriers.

The deck is connected monolithically with the two piers, forming a portal frame, and rests on neoprene bearings at the abutments. The deck is a single-cell box  wide, whose depth varies between  between the piers and central areas or near abutments.
The piers, with a single shaft in their full height, are made of reinforced concrete. Some of the piers reach 40 m in height. The pylon coincides with the pier axis under the box girder. Pylon is  high and has rectangular cross-section linearly variable.

The geometric main features of the bridges are as follows:

Kantutani Bridge: the bridge has three spans of 
Choqueyapu Bridge: the bridge has three spans of 
Orkojahuira Bridge: the bridge has three spans of 

The total cost of the structure was approximately US$18.3 million.

The project was awarded with the Eugene C. Figg, Jr. Medal for Signature Bridges at the International Bridge Conference (Pittsburgh, June 2012),
at a city that also has 3 very similar bridges -- Three Sisters (Pittsburgh).

Construction
The bridge construction began in November 2007 and was completed in mid-2010 to coincide with the commemoration of the Bicentennial of Independence.

New South Wales S type carriage stock. The S type carriage stock was a type of steel passenger carriage operated by the New South Wales Government Railways from 1935 until 1989.

History
Between 1935 and 1937, Clyde Engineering built 35 first class BS carriages with 42 seats and 86 second class FS side corridor carriages with 64 seats at its Granville factory.

Over the years, they operated on services from express passenger and mail trains to branch line services. Withdrawals commenced in the 1970s but some lasted until the late 1980s on mail trains to Dubbo, Moree and Tenterfield and Interurban services to Newcastle, Bathurst, Goulburn and Bomaderry.

During the period spanning 1974 to 1982, eight were gutted internally and fitted with suburban throw over seating and Beclawat windows for use on interurban services. These received the IFS and MFS classifications. As of June 1986, 32 remained in service with the State Rail Authority.

Surviving S type cars

Preservation
Many were sold to preservation organisations with East Coast Heritage Rail, Canberra Railway Museum, Lachlan Valley Railway and New South Wales Rail Transport Museum (now NSW Rail Museum) all having operational examples. Four were purchased by Hamersley Iron in Western Australia for use with their preserved British steam locomotive 4079 Pendennis Castle.
