Relativistic electron beam. Relativistic electron beams are streams of electrons moving at relativistic speeds. They are the lasing medium in free electron lasers to be used in atmospheric research conducted at entities such as the Pan-oceanic Environmental and Atmospheric Research Laboratory (PEARL) at the University of Hawaii and NASA. It has been suggested that relativistic electron beams could be used to heat and accelerate the reaction mass in electrical rocket engines that Dr. Robert W. Bussard called quiet electric-discharge engines (QEDs).

Brac Systems. Brac Systems, Inc assets were acquired by Greyter Water Systems in May 2012. Brac was a company that specialized in the development of water saving products for both residential and commercial use. Brac Systems Inc. was founded by Dennis Yasar in Montreal, Quebec, in February 2005.

Brac Systems began with the development of the GRS greywater recycling systems in 2005. Later, it manufactured and marketed greywater, rainwater and blackwater recycling systems. Brac's residential greywater recycling systems (RGW Systems) capture greywater from the showers, bathtubs, lavatories and laundry washing machines after which it's redistributed to the toilets or used for irrigation. Based upon statistics from Environment Canada, the company asserted that the use of their system will cut the average home's water consumption and sewage effluent by approximately one third.

In 2007, Brac Systems was named the Best New Product in the Energy Efficiency category at Mécanex/Climatex 2007, an annual plumbing and mechanical trade show held in Montreal. Brac's recycling system was also named one of the "Top Ten Green Building Products of 2007" by Sustainable Industries Journal, a publication for the green building industry.

Brac's greywater and rainwater assets were purchased by Greyter Water Systems in 2012. Greyter advanced Brac's commercial buildings technology which has been sold to customers such as the US and Canadian military and the Ontario Ministry of Education.

Optare Prisma. The Optare Prisma was a single-decker bus body that was fitted to the Mercedes-Benz O405 chassis, produced between 1995 and 1998, when it was discontinued in favour of the integral Optare Excel low-floor bus.

Design
The Optare Prisma body was constructed on the O405 chassis with an OM447H  engine, and was built with Alusuisse aluminium framework, retaining a Mercedes-Benz built front cowl and destination display as standard. The sides and back end of the body, however, followed the styling of other Optare products at that time, such as the Delta and Vecta. The Prisma was also designed with the ability to have equipment for use on a guided busway fitted, with a demonstrator operated by Stagecoach Busways in 1996 being fitted with an AEG electronic guidance system.

Capable of seating up to 54 passengers, to meet Disabled Persons Transport Advisory Committee (DiPTAC) accessibility recommendations, the Prisma has a  step at the entrance door, capable of being reduced to  with a kneeling front air suspension. The passenger compartment could be optioned with three further low steps towards the rear of the bus or a ramped floor towards the rear. Gasket-glazed tinted side windows were fitted as standard.

Operators
The most popular operator of Optare Primas was the GRT Group, who took delivery of a total of 35 Prismas for its main Grampian Regional Transport subsidiary between 1995 and 1997, the first ten of which were equipped with double-glazed windows and air-conditing, as well as ten for its SMT "Diamond" services in Edinburgh, and ten for the Leicester Citybus subsidiary. After the company had rebranded to FirstBus, subsidiaries First Midland Bluebird and Lowland took further deliveries of Prismas.

Another large operator was North East Bus subsidiary Tees & District, who took delivery of 25 Prismas in late 1995, followed by East Yorkshire Motor Services, who took delivery of 16 Prismas between 1996 and 1998; three delivered to the operator from stock in 1998 were the last Optare Primsas produced. Smaller operators of Prismas included Sargeants of Kingston upon Thames, the first new full-size bus delivered to the company since World War II, Black Prince Buses of Morley, the Tillingbourne Bus Company of Cranleigh, MacEwan of Dumfries, and Rhondda Buses.

CyberQuery. Cyberquery is a software product of Cyberscience Corporation Inc. Originally developed for data handling and analysis on Data General AOS and AOS/VS minicomputers, then the available platforms for Cyberquery were extended to all major UNIX platforms, OpenVMS, and Microsoft Windows.

Description of Cyberquery

Invented in 1980, Cyberquery is a declarative "4GL" fourth-generation programming language. Its early design was slightly influenced by RAMIS and other data access and analysis languages such as the query language on GE time sharing systems. Cyberquery automates the process of accessing files or tables and reading records or rows. This basic operation allows the user/developer to concentrate on the details of working with the data within each record, in effect working almost entirely within an implicit program loop that runs for each record. Compared to general-purpose programming languages, this automation allows the user/developer to ignore the technical details of the data and how it is stored, and concentrate on the information contained in the data.

Cyberquery has a data dictionary to describe the datasets users wish to access. This removes all the physical details of the file structure from each program and from the user/developer. The original target customers for Cyberquery were personnel departments, so ease of use by non computer specialists was an early design goal. This architecture had the advantage that Cyberquery is portable, reports written for one database run unmodified on any other provided the underlying data is logically similar. Differences are hidden in the data dictionary. Cyberquery is now widely deployed in Industries including Manufacturing, Finance, Medical and Retail.

Cardington test. The Cardington Fire Tests were a series of large-scale fire tests conducted in real structures (wood, steel-concrete composite, and concrete) at the BRE Cardington facility near Cardington, Bedfordshire, England, during the mid-1990s.  After the tests, extensive computational and analytical studies of the behaviour of steel-framed composite structures in fire conditions were carried out by, among others, the University of Edinburgh, Sheffield University, and Imperial College London.

The results were presented in the form of a main report, which identified the main findings, together with numerous supplementary reports exploring various phenomena in detail.

Poshlib. Posh is a software framework used in cross-platform software development. It was created by Brian Hook. It is BSD licensed and , at version 1.3.002.

The Posh software framework provides a header file and an optional C source file.

Posh does not provide alternatives where a host platform does not offer a feature, but informs through preprocessor macros what is supported and what is not. It sets macros to assist in compiling with various compilers (such as GCC, MSVC and OpenWatcom), and different host endiannesses. In its simplest form, only a single header file is required. In the optional C source file, there are functions for byte swapping and in-memory serialisation/deserialisation.

Brian Hook also created SAL (Simple Audio Library) that utilises Posh. Both are featured in his book "Write Portable Code". Posh is also used in Ferret and Vega Strike.

Sieving coefficient. In mass transfer, the sieving coefficient is a measure of equilibration between the concentrations of two mass transfer streams.  It is defined as the mean pre- and post-contact concentration of the mass receiving stream divided by the pre- and post-contact concentration of the mass donating stream.

where
 S is the sieving coefficient
 Cr is the mean concentration mass receiving stream
 Cd is the mean concentration mass donating stream

A sieving coefficient of unity implies that the concentrations of the receiving and donating stream equilibrate, i.e. the out-flow concentrations (post-mass transfer) of the mass donating and receiving stream are equal to one another.  Systems with sieving coefficient that are greater than one require an external energy source, as they would otherwise violate the laws of thermodynamics.  

Sieving coefficients less than one represent a mass transfer process where the concentrations have not equilibrated.  

Contact time between mass streams is important in consider in mass transfer and affects the sieving coefficient.

In kidney
In renal physiology, the glomerular sieving coefficient (GSC) can be expressed as:
sieving coefficient = clearance / ultrafiltration rate

Moheshkhali Upazila. Moheshkhali () is an upazila of Cox's Bazar District in the Division of Chittagong, Bangladesh. 

The government's ambitious project to transform Maheshkhali Island in the Bay of Bengal into a thriving energy hub aims to establish power plants and a liquefied natural gas (LNG) terminal by 2027. This endeavor is driven by the objective of strengthening the country's economy and achieving self-reliance in the power and fuel sector. As a result of this initiative, the country's energy crisis will improve significantly, and the socio-economic landscape of the region will become more sustainable.

To support this transformation, the government is constructing substantial oil storage infrastructure at Kalamarchara in Maheshkhali as part of the Single Point Mooring (SPM) project. This pipeline system will not only save time but also reduce expenses by approximately TK 800 crore annually. The Maheshkhali terminal will be equipped with six storage tanks, three for diesel and three for crude oil, allowing for storage capacities of approximately 115,000 tonnes of crude oil and 75,000 tonnes of diesel. This strategic storage capability will further bolster the country's energy security and reinforce its position as a robust energy hub in the region. According to the Maheshkhali Upazila Nirbahi, the Single Point Mooring (SPM) project holds paramount importance to the prime minister. The successful execution of this project is expected to generate employment opportunities for the local population, leading to the eradication of unemployment in this region.

Electronic carillon. Electronic carillon is a blanket term used to refer to an automated system which imitates the sound of a carillon.  These systems simulate and amplify bell sounds which are then played from loudspeakers housed in a bell tower.

Due to the costs associated with installing, maintaining, and operating traditional carillons, many churches and universities now use these types of systems.

Bell Sound Emulation
While a traditional carillon uses actual bells, electronic systems simulate a bell sound in several ways
 By striking semantra (rectangular metal bars roughly the diameter of a pencil, but of varying lengths) with an electric solenoid.
 By striking tubular bells similarly
 By playing back a previously recorded bell sound
 By striking a small number of actual bells in combination with the methods above

Operation
Electronic carillons use internal electronic clocks to determine when chimes or music will be played.  The Westminster Quarters are commonly programmed to chime the hour and its divisions, along with musical selections. The musical score is stored on media which can typically be changed or expanded.  

Systems may also provide a keyboard or console.  This allows a musician to operate the instrument in a manner similar to the way a traditional carillon is operated.  These keyboards are sometimes integrated with or attached to an organist's console.

Early automated carillons used electric timers that simply played selected bell strikes or tunes.  Modern computerized carillons can be programmed to play selections for Easter, as well as other fixed and movable holidays.

Since these systems use an amplifiers and loudspeakers, many are being expanded to also provide emergency notification systems to college campuses.

Enhanced television. Enhanced Television (ETV) is a collection of specifications developed under the OpenCable project of CableLabs (Cable Television Laboratories, Inc.) that define an ETV Application consisting of resources (files) adhering to the Enhanced TV Binary Interchange Format (EBIF) content format as well as:

PNG images
JPEG images
PFR downloadable fonts

An ETV application is normally delivered through an MPEG transport stream and accompanies an MPEG program containing video and audio elementary streams.

ETV Application 

An ETV Application is a collection of resources (files) that include one or more EBIF resources that represent viewable information in the form of pages.

Two forms of a given ETV Application may be distinguished: (1) an interchange form and (2) an execution form. The interchange form of an ETV Application consists of the resources (files) that represent the compiled application prior to its actual execution by an ETV User Agent. The execution form of an ETV Application consists of the stored, and possibly mutated forms of these resources while being decoded, presented, and executed by an ETV User Agent.

ETV User Agent 

An ETV User Agent is a software component that operates on a set-top box, a television, or any other computing environment capable of receiving, decoding, presenting, and processing an ETV Application. This component usually provides, along with its host hardware environment, one or more mechanisms for an end-user to navigate and interact with the multimedia content represented by ETV Applications.

BM/85 mine. The BM/85 is an Italian blast resistant bounding anti-personnel mine that was produced by Tecnovar italiana SpA. The mine is cylindrical with a three pronged tilt/pressure fuze on the top with a central post for attaching a tripwire. A plastic safety clip prevents the fuze from tilting when in transit. Once the pressure clip is removed the mine is armed. Once the fuze is pulled sideways by a trip wire or by downward pressure, the mine is triggered. A small charge launches the mine to a height of about 0.45 meters where it explodes scattering 1,000 fragments to a lethal radius of about 25 meters.

The mine is similar to the Valmara 69, both share a similar fuze mechanism which is resistant to blast overpressure making them difficult to clear rapidly.

The mine was in service with the Italian army but all operational stocks of the mine have been destroyed.
