Underreamer. An underreamer is a device used to enlarge the borehole below an existing casing or restriction, during a well drilling operation.
It can be positioned either above the drill bit or above a pilot assembly run inside the existing borehole.

Numerous designs exist, in sizes varying from a couple of inches to above 40". It is typically used in hydrocarbon drilling operations, but also geothermal or water wells drilling.

This device is typically composed of a body connected to the drillstring, and of mobile parts ("arms", "blocks" or "blades", typically 3 of them) retracted in the body during the descent and extended downhole for the reaming operation. Reaming itself can be conducted either in an existing borehole ("pilot reaming") or during the drilling operation ("reaming while drilling").

Underreaming is primarily used to allow a wider clearance for running and cementing the casing correctly, either due to restrictions (swelling shales, tortuosity) or to be able to run a larger casing size. It is commonly used for offshore drilling operations, exploration wells, extended reach drilling or to increase the size of the production liner.

3 primary designs have been developed over the years. In chronological order :
- "Roller-cone" type underreamers, based on roller cone cutters technology, were often plagued by low reliability and limited bottom hole time
- "hinge-and-pin" PDC 
- "block-type" PDC, commonly used today, suitable for reaming-while-drilling operations.

Underreamers are also required for directional casing-while-drilling (or "drilling with casing") services, to allow the directional BHA to be retrieved through the casing, either at the end of drilling, or when a change of equipment is needed.

Effective fragment potential method. The effective fragment potential (EFP) method is a computational approach designed to describe intermolecular interactions and environmental effects. It is a computationally inexpensive means to describe interactions in non-bonded systems. It was originally formulated to describe the solvent effects in complex chemical systems. But it has undergone vast improvements in the past two decades, and is currently used to represent intermolecular interactions (represented as rigid fragments), and in molecular dynamics (MD) simulations as well.

Sikorsky S-33 Messenger. The Sikorsky S-33 Messenger was an American two-seat sesqiuplane designed and built by the Sikorsky Manufacturing Corporation in 1925.

The first of two examples built participated in the Sixth Pulitzer Trophy Race at Mitchel Field, Long Island, New York on October 12, 1925 and was piloted by Al Krapish, an employee of Sikorsky.

The first aircraft is reported to have been powered by a Wright Gale of  and the second by a Lawrance L-3 of . These were essentially the same engine type, post- and pre- acquisition of the Lawrance Aero Engine Company by the Wright Aeronautical Corporation, respectively. Some sources assert that the aircraft was powered by an Anzani engine, but this is most likely to be a mis-identification.

BS Nymph. The BS Nymph was a fibreglass monocoque British buggy based on running gear from the Hillman Imp, including its rear-mounted 875 cc engine. While meant by Chrysler UK to enter series production to the tune of 4000 cars per annum, the Chrysler corporation discontinued the Imp before the Nymph was released. Rather than competing globally with the Mini Moke as intended, the Nymph entered small-scale production as a kit car and only 42 cars were finished. The designers, Peter Bohanna and Robin Stables, are perhaps best known for having designed the "Diablo GT", which later was developed into the AC 3000ME.

Design
The Nymph used almost all of the Imp parts aside from the body, with most of the hardware bolted directly to its GRP monocoque. This body was moulded in colour and also fire-retardant. At the time of introduction, a construction time of 50-60 hours were claimed. Doors and a hardtop, as well as a "Surrey"-style softtop, were available as options. By 1977, production had ended as Bohanna and Stables had moved on to other projects and given up on manufacturing.

Dammam Metro. Dammam Metro is a proposed metro rail system for the Dammam metropolitan area in the Eastern Province of Saudi Arabia. The project is estimated to cost SAR 60 billion (US$ 16 billion), and was originally expected to be completed by 2021.

History
An integrated public transport system for Dammam was approved by the Council of Ministers on 19 May 2014, and publicly announced by Eastern Province Mayor Fahad Al Jubair on 21 May 2014. The project includes 50 km of light rail, 110 km of bus rapid transit, and 350 km of feeder buses to link the outskirts of the city. The Council also approved the establishment of a private company to monitor the implementation of the project.

The light rail system will have two lines. The first line will link Tarout Island with King Fahd Causeway via Qatif, Dammam and Dhahran. The second line will connect King Fahd Road in Dammam to the King Fahd International Airport. Studies to finalize the alignment and location of the stations will take an estimated 18 months.

At the Middle East Rail 2017 conference and exhibition in Dubai on 7 March 2017, President of the Public Transport Authority Rumaih Al Rumaih stated that the Dammam Metro project would be developed as a public private partnership.

Juan Rivero Torres. Juan Ramón Rivero Torres (January 17, 1897 – June 29, 1951), was a Bolivian engineer and businessman responsible for the development of several cross-border infrastructure projects that improved regional integration in South America during the first half of the 20th century. The completion of the railroad connecting Santa Cruz, Bolivia to Corumbá, Brazil effectively linked South America's Atlantic and Pacific coasts.

In 1941, President Getúlio Vargas awarded him with the Ordem Nacional do Cruzeiro do Sul, the highest award bestowed by the Brazilian government to a foreigner, for his services in the development of regional transport infrastructure.

Biography 

Born in Cochabamba, Bolivia, one of two landlocked South American countries, he was the son of industrialist Ramón Rivero and the nephew of poet Adela Zamudio. He was educated at the Swiss Federal Institute of Technology at Zurich, Switzerland, where in 1921 he received an honors degree in civil engineering. As a young engineer, he was driven and determined to address the special challenges faced by his landlocked country and help Bolivia overcome its geographical disadvantages.

Pan-American Highway 

After he took part as a student in the Bolivian delegation in Geneva, Switzerland, as the initial sessions of the General Assembly of the League of Nations were called to order, President Bautista Saavedra recognized his unique diplomatic skills and sent him as an engineer to the initial meetings of the Pan-American Highway Commission, in 1924 at Washington, D.C., and the following spring of 1925, at Buenos Aires, Argentina, where he served as vice president of the commission. A modern highway from the northern part of North America to the southern part of South America had been under official consideration since 1923, when the Fifth International Conference of American States met at a Santiago, Chile. He came to believe in the project, and became an early advocate for it in Bolivia, which signed the Convention on the Pan-American Highway in 1937.

Lloyd Aéreo Boliviano 

Between 1923 and 1937, he served as chief engineer of rail and air transport for the Ministry of Economic Development, where he was instrumental in the creation of Lloyd Aereo Boliviano, one of South America's oldest airlines.

Santa Cruz-Corumbá Railway 

In 1938, he was appointed chief of the Bolivian delegation to help organize the Mixed Bolivian-Brazilian Railway Commission; until 1951, he served as delegate engineer of Bolivia in the construction of the Santa Cruz-Corumbá Railway, thereby forming a rail corridor to connect South America's Atlantic ports with its Pacific ones.

General Dynamics Mission Systems - Canada. General Dynamics Mission Systems - Canada, formerly Computing Devices Canada, is a technology-based electronic systems, systems integration, and in-service support to defence organizations and public security markets in Canada and abroad. Its parent company is General Dynamics.

History
Computing Devices Canada was incorporated on August 31, 1948 as a global defence contractor. The company was founded by two Polish immigrants to Canada, George Glinski and Joe Norton, to support the rebuilding of Canada's military after the Second World War. The company got its start by manufacturing the Position and Homing Indicator (PHI), a device developed at the National Research Council that kept track of an aircraft's position and indicated its return route to base. One large contract that had a significant influence on the company's growth was for the Kicksorter, a digital-pulse counter designed for the Atomic Energy of Canada Laboratories (AECL) in Chalk River. If the Kicksorter had been slightly modified to do simple arithmetic operations, it would have been a rudimentary computer. AECL purchased a large number of these devices between 1957 and 1963, when they were replaced by one of the early computers in the PDP series manufactured by the Digital Equipment Corporation (DEC). Another contract was to design and construct a large digital simulator for the Royal Canadian Navy that was never completed.

During the 1990s, Computing Devices Canada implemented the Iris Digital Communications System, which was a thorough communications upgrade for the Canadian Army, and on the strength of that effort, was awarded the Bowman contract to perform a similar effort for the British Army.

In 1998, General Dynamics purchased the company, renaming it to General Dynamics Canada.

Products and programs

The Aurora Program is the mid-life upgrade of the CP140 Aurora aircraft operated by the Canadian Department of National Defence as a long-range maritime patrol platform for surface and undersea surveillance roles. GD Mission Systems — Canada has been contracted to develop the Data Management System (DMS) and Acoustic Suite subsystems. The latest release brings with it new capabilities in terms of Link 16, BLOS-WGS satcom and self-defence in the form of a Directed IR Countermeasures system (DIRCM).

In 2014, they were awarded two contracts on the Mercury Global Project.  The first contract is for the design-and-build of a network of Mercury Global anchor stations valued at $59.1 million.  Through this network of antennas, the Department of National Defence will access the Wideband Global Satellite (WGS) constellation and will be able to provide secure communications for deployed Canadian Forces. The second contract provides ongoing in-service support and is valued at $8.5 million.

Altgeld Hall (SIUC). Altgeld Hall is a building on the campus of Southern Illinois University Carbondale. It is the oldest currently occupied structure on the campus.

History and architecture
Construction was authorized by Governor John Peter Altgeld in 1895 as part of a program of expansion of state funding for education. The architect was C. W. Rapp of Chicago, a Carbondale native, and the contractors were M. T. Lewman & Company of Louisville, Kentucky. The cornerstone was laid July 21, 1896 by Owen Scott, former United States Representative. The building was dedicated December 22, 1896 by then president of the school, Harvey W. Everest.

As originally designed, the building housed the university library and laboratories for the departments of physics, chemistry and biological science, as well as a gymnasium. Following a major remodeling project in 1958, Altgeld Hall became the home of the SIUC School of Music. From 2002 to 2004 the building underwent a major restoration and renovation project, which included a large addition to the west side. The architects of the project were White & Borgognoni of Carbondale.

Altgeld Hall is one of a group of five buildings known as Altgeld's castles. Altgeld authorized these buildings as part of increased state investment in education, but also wielded influence over their design. Four of the five, including the SIUC building, were designed in what Altgeld described as the "Tudor-Gothic style," his preferred style for public buildings built during his term of office. Through his influence these buildings were part of the larger Collegiate Gothic movement.
