IntelliServ. IntelliServ is a National Oilwell Varco brand that manufactures and sells a broadband networked drilling string system used to transmit downhole information to the surface in a drilling operation.

Background

The IntelliServ network is a broadband telemetry system that allows instant transmission of data between the surface and the measurement tools positioned in the drill string bottom-hole assembly near the drill bit. IntelliServ originated in a 1997 project on hydraulic mud hammers sponsored by the company Novatek and the United States Department of Energy. The project addressed the need for instant transmission of downhole data (data acquired within the wellhole) through drill pipe, leading to Novatek’s beginning on a networked drill pipe development project.  In 2001, the National Energy Technology Laboratory (NETL) began providing funding for the drill pipe project and an additional drill pipe data transmission project.

in 2006, research resulted in the IntelliServ network and Intellipipe, a drill pipe with an embedded data cable. In 2005, Grant Prideco bought the IntelliServ technology and launched the first IntelliServ network. Grant Prideco was purchased by National Oilwell Varco (NOV) in 2008, and the NOV-IntelliServ joint venture was formed in 2009 with 55% National Oilwell Varco and 45% Schlumberger ownership.

The first commercial deployment of a drill string telemetry network occurred using IntelliServ’s product in Myanmar in December 2006.

Technology
The IntelliServ network components are embedded in drill string components, known as IntelliPipe, which transmit subsurface data at 57,000 bits per second. The IntelliServ network upgrade raised the speed to one million bits per second. The two-way data communication between downhole Measurement while drilling (MWD) and Logging while drilling (LWD) measurement tools and the operators  at the surface allow the operators to command rotary-steering tools, or configure downhole tools such as the formation pressure testing tool or sonic tools.

The IntelliServ network includes measurement nodes along the full length of the drill string that allow operators to acquire data along the wellbore. The measurement nodes measure and transmit temperature and pressure data acquired along the drill string, which can improve well site efficiency and reduce risks associated with hole cleaning, such as pack offs. The transmission of information is not affected by the depth, formation resistivity, drilling fluid properties, or required flow of the well. Surface operating parameters can control items detected by the sensors, such as shock and vibration.

The networked drill pipe can transmit data acquired by most large service companies.  As of March 2012, the system has been deployed on 90 wells totaling more than 1 million feet of drilling.

Iron Sky: Invasion. Iron Sky: Invasion is an official video game based on the 2012 Finnish science fiction comedy Iron Sky. The game is developed by Reality Pump Studios, and is published by TopWare Interactive.

Iron Sky: Invasion is a space fighter simulator, enhanced with strategic and RPG elements, set in the universe of Iron Sky and expanding upon its foundations. The core of the gameplay is based on ship-to-ship dogfights, combined with assaults on giant spaceships (such as the space Zeppelins, portrayed in the film), as well as tactical thinking and resource management.

The game was first announced on August 19, 2012, by the video game publisher TopWare Interactive, during the Gamescom trade fair in Cologne, Germany. It was released in Europe on December 12, 2012, for the Windows, Xbox 360, PlayStation 3, iOS, Android, and Mac OS platforms. It has received mixed to negative reviews from critics.

Gameplay
The game takes place in outer space, where the players must defend the Earth from the invasion of the Moon Nazis, as depicted in the 2012 film. The players can control most of the spaceships from the movie, to freely roam the space and attack Nazi vessels. There are weapons and equipment at their disposal, from offensive systems to defensive drones and satellites. The vessels are also equipped with military countermeasures which protect them from enemy fire, and can be recharged, upgraded, or traded for other models. Upgrades require special resources, which can be scavenged from destroyed enemy units or found in outer space. A tactical space map can be used to spot the positions of Nazi forces or ongoing battles, with the destruction of the secret Nazi base hidden on the Dark Side of the Moon set as the ultimate goal.

Hydration energy. In chemistry, hydration energy (also hydration enthalpy) is the amount of energy released when one mole of ions undergoes solvation.  Hydration energy is one component in the quantitative analysis of solvation. It is a particular special case of water. The value of hydration energies is one of the most challenging aspects of structural prediction.  Upon dissolving a salt in water, the cations and anions interact with the positive and negative dipoles of the water.  The trade-off of these interactions vs those within the crystalline solid comprises the hydration energy.

Examples
If the hydration energy is greater than the lattice energy, then the enthalpy of solution is negative (heat is released), otherwise it is positive (heat is absorbed).

The hydration energy should not be confused with solvation energy, which is the change in Gibb's free energy (not enthalpy) as solute in the gaseous state is dissolved. If the solvation energy is positive, then the solvation process is endergonic; otherwise, it is exergonic.

For instance, water warms when treated with CaCl2 (anhydrous calcium chloride) as a consequence of the large heat of hydration. However, the hexahydrate, CaCl2·6H2O cools the water upon dissolution. The latter happens because the hydration energy does not completely overcome the lattice energy, and the remainder has to be taken from the water in order to compensate the energy loss.

The hydration energies of the gaseous Li+, Na+, and Cs+ are respectively 520, 405, and 265 kJ/mol.

Crepelle. Crepelle is a French manufacturer of compressors and engines. Founded as Crepelle and Company in 1837, it has a history going back to the early days of industrial engine manufacturing in France. Crepelle was acquired by the Swedish group Atlas Copco in 1997.

History

Founded in 1837 in Lille, France, the company was an early innovator of steam engine technology. The company became Crepelle and Garand in the late 19th century. The company's steam engines were to be found in many steam ships operating in the 19th century. The company later produced diesel (oil) engines and compressors, introducing its first gas compressors in 1930.

Several examples of the industrial engines produced by Crepelle in the 19th century survive. One notable example is a large 1889 Corliss valve horizontal single cylinder steam engine. From 1974 until 2006, it was on exhibit at the British Engineerium museum in West Blatchington, Brighton and Hove, East Sussex, United Kingdom. This engine won a gold medal at the 1889 Paris Exhibition. The engine is a restored working engine. It was used to generate electricity for a hospital in France until 1940.

Kometa-Standard. The Kometa-Standard was a Standard Class glider, designed and built in Bulgaria in the early 1960s. Thirty were flown by local gliding clubs.

Design and development
The Kometa-Standard was the second glider designed by Pavlov and Panchovsky, a fully aerobatic Standard Class aircraft of almost entirely wooden construction, though with fabric covered control surfaces.  The wings, straight tapered in plan and set at mid-wing position, were single spar structures with leading edge plywood covered D-boxes. They had 4° of dihedral. There were salmon type fairings, tapering, slender, streamlined bodies, at the tips. The Kometa-Standard had mass-balanced, slotted ailerons and spoilers at 60% chord which opened above and below the wing.

The fuselage of the Kometa-Standard was a plywood covered monocoque with the cockpit extending close to the metal nose cone.  The canopy of the prototype was of long bubble form, proud of the rear fuselage line, but this was lowered and reshaped on the production Kometa-Standard II, merging into the rear fuselage from which it was hinged. The cockpit was changed again in the Kometa-Standard III which had a sliding canopy over a reclining seat, making this variant 30 km/h (19 mph) faster than the Kometa-Standard II. Overall, the fuselage tapered uniformly from the cockpit to the tail. The Kometa-Standard had a 110° butterfly tail, its plywood and fabric covered surfaces terminating, like the wings, in little salmon fairings.  Its undercarriage was a fixed monowheel, fitted with a brake and assisted by a forward, rubber sprung skid.

Operational history
The prototype was flown for the first time on 5 August 1960 and an initial batch of 10 Kometa-Standard IIs was built, followed by two batches, each of 10, of Kometa-Standard IIIs. Flown by Bulgarian clubs, they were fully aerobatic, though not cleared for cloud flying.

Variants

S2o design and engineering. S2o Design and Engineering were the detailed designers of the London 2012 whitewater venue.  The selection of this team to design the Olympic venue was unique because the designer was a former Olympic competitor ('92, '96, '00) who started a firm to design whitewater parks after receiving a degree in Engineering.  The company was started in 2003 by Scott Shipley.  Scott Shipley is a registered professional engineer who was formerly a World Cup Slalom Champion and World Silver Medalist in both freestyle kayaking and slalom kayaking.

S2o Design and Engineering worked with Engineering Paddler Designs to create the Rapidblocs Obstacle system.  The  system is currently patent pending and was used in the design of the London 2012 whitewater venue at the Lee Valley White Water Centre.

RapidBlocs. RapidBlocs are a movable obstacle system for artificial whitewater courses. The system was developed by Scott Shipley of S2o Design and Engineering and Andy Laird of Engineering Paddler Design. The system was developed for the Lee Valley White Water Centre that was used for the 2012 London Olympic Games. The system is made of modular blocks that can be secured via unistruts at any point in a compatible channel. The blocks are stackable and can therefore be combined to create a variety of shapes. These shapes are configured to create waves, eddies other hydraulic jumps. There are also a variety of utilitarian configurations that can be created to make stairs, rescue platforms, and to configure varying rescue scenarios for rescue training. At the London Games the RapidBloc system created all of the waves and features and was also used to create the starting gate.

The system has been used in a variety of channels that were either custom built for the system or have been retrofitted to an existing channel – as in the case for the Tees Barrage International White Water Course and the Prague-Troja Canoeing Centre in Prague.
