Felsenau Power Plant. The Felsenau power plant () is a hydroelectric power plant located on the river Aar in Bern, Switzerland. It was built in 1909 by the city's utility company, Energie Wasser Bern. After a 1989 modernisation, the turbine hall is now used as a museum. The plant's current power output is 11.5 megawatts.

The main building was designed by Eduard Locher and Alfred Brunschwyler in a then-popular historicising style as a "palace of technology". The 1989 expansion is by Vladimir Grossen and Bea Baumann.

AeroVironment FQM-151 Pointer. The AeroVironment FQM-151 Pointer is a small UAV used by the United States Army and Marine Corps for battlefield surveillance. It was designed by AeroVironment Incorporated, formerly led by Paul MacCready, noted for such pioneering aircraft as the human-powered Gossamer Condor and a robotic flying pterodactyl replica. The Pointer was developed with company funds, with the US Army and Marine Corps obtaining a total of about 50 units beginning in 1990.

The radio-controlled Pointer was built mostly of high-impact Kevlar. It resembled hobbyist's RC sailplane with a small engine added, with the wing standing up above the fuselage on a pylon and a pusher propeller on the wing behind the pylon. A lithium battery pack powered the UAV's compact electric motor to rotate the propeller. The little Pointer was hand-launched. It was recovered simply by putting it into a flat spin, allowing it to flutter down to the ground.

The Pointer carried a CCD camera fixed in its nose, meaning it had to be directly pointed at its target to see it, which is how the machine got its name. The CCD camera had a resolution of 360 x 380 pixels and a viewing aperture of 22 x 30 degrees. Video could be fed back to the ground station by radio or fiber-optic link.

The ground station recorded flight imagery on an eight-millimeter video cassette recorder. Digital compass headings were superimposed on the imagery and the controller could add verbal comments. The imagery could be inspected with normal, freeze-frame, fast, or slow-motion replay. The aircraft system and the ground control station were carried in separate backpacks. It required a pilot and an observer.

The Pointers in US military service have now been upgraded with a GPS/INS capability, and it has led to a number of derivatives. chapter. The Pointer itself remains in use, having seen action during the intervention in Afghanistan in 2001 and the invasion of Iraq in 2003.

Deviation survey. In the oil industry, a deviation survey, or simply a survey, is the measurement of a borehole's departure from the vertical, expressed in degrees (°).

When a well plan dictates the drilling of a straight borehole, surveys are periodically taken to ensure that it will hit its target and also to ensure that it does not trespass underneath different property lines. These surveys can be taken fairly simply with a mechanical drift recorder, more commonly known as a Totco or Totco barrel (named after the company that perfected the device). This device is run inside the drill string attached to a wire on a wireline unit, down to the bottom of the drill pipe where the device (which is simply an inverted pendulum with a timer that punches a pin-hole onto a round paper tab delineated with concentric circles indicating increments of degrees) measures the angle of the hole and then is pulled back out to visually inspect to determine the angle. There are versions of this device that actually take a picture on film and are often used in situations where the azimuth (direction) needs to be determined also.

When a well plan dictates a directional or horizontal borehole, more sophisticated tools are normally used. One such tool is the MWD (measurement while drilling) tool that uses electronic accelerometers and gyroscopes, to continually take surveys while drilling (as the name suggests) and also measures the azimuth (direction). This tool is attached to the drill string itself and requires extra support personnel to use and interpret the data, and its costs are much more substantial. (See well logging)

Kang Rixin. Kang Rixin (; born August 1953) is a Chinese former nuclear engineer and politician. He served as chief manager of China National Nuclear Corporation (CNNC) and was a member of the 17th Central Committee of the Chinese Communist Party. He was sentenced to life imprisonment in 2010 for corruption.

Biography
Kang was born in Datong, Shanxi, China and graduated from the department of nuclear engineering of Shanghai Jiaotong University in August 1978. He joined the Chinese Communist Party (CCP) in December 1982. In January 2005, he graduated from the graduate school of the CCP Central Party School, majoring in economics management. In June 2005, he obtained an EMBA certificate from Tsinghua University. He is a senior engineer at the researcher level.

From 2003 to 2009, he managed the China National Nuclear Corporation (CNNC), before being accused of corruption and bribery. Kang was sentenced to life imprisonment and confiscation of his possessions by a Beijing court in 2010 because he accepted about one million US dollars in bribes between 2004 and 2009.

Kang was a member of the 17th Central Committee of the Chinese Communist Party from 2007. He was expelled from the CCP after his bribery conviction.

BAE Systems SkyEye. The BAE Systems SkyEye is a reconnaissance UAV developed in the United States in the early 1970s by Developmental Sciences Inc, later called Developmental Sciences Corporation, a division of Lear Astronics Corporation and ultimately part of BAE Systems. Developmental Sciences Inc was one of the first US companies to investigate battlefield UAVs, flying the first prototype of the SkyEye series in 1973, leading to the first flight of the improved R4E variant in 1981. The R4E has been continuously refined since then in a sequence of subvariants.

The R4E SkyEye is in service with a number of countries, including Egypt and Morocco, for battlefield surveillance, and has also been used commercially for pesticide spraying. Apparently a few stock R4Es were also purchased by the US Army's South Command in Latin America and used for border patrols. The US Army had also considered a variant of it, the McDonnell Douglas Sky Owl, for the short-range UAV competition. As the Sky Owl, McDonnell Douglas leveraged it into the company's proposal for the Army competition, but apparently it proved generally inferior to the RQ-5 Hunter.

The SkyEye has the common pusher-propeller twin-tailboom configuration, but it has distinctive slightly swept wings and antennas on top of the tailplanes. It is powered by a UAV Engines Limited (UEL) 39 kW (52 hp) rotary engine. The SkyEye can carry two underwing stores along with its other payload. It lands on a retractable centerline skid or can be recovered by parachute.

Rotary table (drilling rig). A rotary table is a mechanical device on a drilling rig that provides clockwise (as viewed from above) rotational force to the drill string to facilitate the process of drilling a borehole. Rotary speed is the number of times the rotary table makes one full revolution in one minute (rpm).

Components
The rotary table is also called a turntable. Most rotary tables are chain driven. These chains resemble very large bicycle chains. The chains require constant oiling to prevent burning and seizing. Virtually all rotary tables are equipped with a rotary lock'. Engaging the lock can either prevent the rotary from turning in one particular direction, or from turning at all. This is commonly used by crews in lieu of using a second pair of tongs to makeup or break out pipes. The rotary bushings are located at the center of the rotary table. These can generally be removed in two separate pieces to facilitate large items, e.g. drill bits, to pass through the rotary table. The large gap in the center of the rotary bushings is referred to as the "bowl" due to its appearance. The bowl is where the slips are set to hold up the drill string during connections and pipe trips as well as the point the drill string passes through the floor into the wellbore. The rotary bushings connect to the kelly bushings to actually induce the spin required for drilling.

Alternatives
Most recently manufactured rigs no longer feature rotary drives. These newer rigs have opted for top drive technology. In top drive, the drill string is turned by mechanisms located in the top drive that is attached to the blocks. There is no need for the swivel because the top drive does all the necessary actions. The top drive eliminates the need for a kelly bar or kelly bushings.

Redgate. Redgate Software is a software company based in Cambridge, England. It develops tools for developers and data professionals and maintains community websites. The company describes itself as offering end-to-end Database DevOps to help organizations streamline software development and get value from their data faster. 

Redgate produces database management tools for Microsoft SQL Server, PostgreSQL, Oracle, MySQL and Microsoft Azure. It also produces advanced developer tools for .NET Framework, such as SmartAssembly and .NET Reflector.

From 2007 to 2013, Redgate was featured in the Sunday Times 100 best companies to work for in the United Kingdom. It has won numerous industry awards for its SQL Server management software.

History 
The company was founded by Neil Davidson and Simon Galbraith in October 1999. It is named after Via Porta Rossa (Red Gate Street) in Florence, Italy, close to where Davidson used to live.

In 2005, Redgate launched Simple Talk, an online technical journal and community hub for working Microsoft SQL Server and .NET developers, which has since expanded to include PostgreSQL, MySQL, and Oracle Database. The journal is sponsored by Redgate, but retains editorial independence. In addition to publishing articles, Simple Talk publishes books, most of which are available in a digital format.

On 20 August 2008, Redgate announced it was taking responsibility for future development of the free tool .NET Reflector.

On 22 March 2010, HyperBac Technologies (formerly known as Xceleon Technologies) was acquired by Redgate. HyperBac developed SQL software tools and products.

In August 2009, Redgate launched Springboard, a startup incubator based in Cambridge, UK. For a period of three months Redgate provided living expenses and mentoring for teams to work from Redgate's offices. It was similar to Y Combinator and Techstars in that it provided a small amount of capital up front but no equity was taken.

In 2010, Redgate re-launched Springboard with a different model where teams would again receive investment and mentoring, but this time in exchange for an equity stake. One such recipient of investment-for-equity in 2016 was Berlin-based 3T Software Labs, makers of Studio 3T, the IDE for MongoDB, a popular NoSQL database.

On 7 March 2017 Microsoft announced the inclusion of Redgate tools in Visual Studio 2017. Three components were included: ReadyRoll Core and SQL Prompt Core, both in the Enterprise edition of Visual Studio 2017, and SQL Search in all editions.

On 28 January 2021 Redgate announced it had acquired the assets of the Professional Association for SQL Server (PASS).

In December 2021, Redgate announced that Jakub Lamik was taking up the position as CEO of the company, and that Galbraith would remain on the board as a non-executive director.

In 2024, Redgate celebrated its 25th birthday.

Cross bracing. In construction, cross bracing is a system utilized to reinforce building structures in which diagonal supports intersect. Cross bracing is usually seen with two diagonal supports placed in an X-shaped manner. Under lateral force (such as wind or seismic activity) one brace will be under tension while the other is being compressed. In steel construction, steel cables may be used due to their great resistance to tension (although they cannot take any load in compression). The common uses for cross bracing include bridge (side) supports, along with structural foundations. This method of construction maximizes the weight of the load a structure is able to support. It is a usual application when constructing earthquake-safe buildings.

Cross bracing can be applied to any rectangular frame structure, such as chairs and bookshelves. Its rigidity for two-dimensional grid structures can be analyzed mathematically as an instance of the grid bracing problem.

Cross bracing may employ full diagonals, or corner bracing or knee bracing.

The idea of cross bracing is also applied to sport ram-air parachutes to improve their structural integrity.

Mining tunnels

To add rigidity to the construction of mining tunnels, the cross-beam connecting between arches is also a type of cross brace. They are often tubular and modified on the ends with clips or apertures for screw fastening. They serve as a stiffening element for the stability of a design. This brace could also be an ordinary cross-section wooden cross-beam, or even a board.

Cross bracing can be seen in situations like flooring, where cross braces are put between floor joists in order to prevent movement. It is also commonly used for ship making in order to stand against heavy winds or extreme weather.

Niobium monoxide. Niobium monoxide is the inorganic compound with the formula NbO. It is a grey solid with metallic conductivity.

Structure and electronic properties
NbO adopts an unusual cubic structure, similar to the rock salt structure but with some missing atoms compared to it, so that both niobium and oxygen atoms have square planar coordination geometries. The niobium centers are arranged in octahedra, and there is a structural similarity to the octahedral niobium clusters in lower halides of niobium. In NbO the Nb-Nb bond length is 298 pm which compares to 285 pm in the metal. One study of the bonding concludes that strong and nearly covalent bonds exist between the metal centers.

It is a superconductor with a transition temperature of 1.38 K. It is used in capacitors where a layer of Nb2O5 is formed around NbO grains as the dielectric.

Preparation
NbO can be prepared by reduction of Nb2O5 by H2. More typically, it is prepared by comproportionation:
Nb2O5  + 3 Nb → 5 NbO
