Dielectric gas. A dielectric gas, or insulating gas, is a dielectric material in gaseous state. Its main purpose is to prevent or rapidly quench electric discharges. Dielectric gases are used as electrical insulators in high voltage applications, e.g. transformers, circuit breakers (namely sulfur hexafluoride circuit breakers), switchgear (namely high voltage switchgear), radar waveguides, etc.

For high voltage applications, a good dielectric gas should have high dielectric strength, high thermal stability and chemical inertness against the construction materials used, non-flammability and low toxicity, low boiling point, good heat transfer properties, and low cost.

The most common dielectric gas is air, due to its ubiquity and low cost. Another commonly used gas is a dry nitrogen.

In special cases, e.g., high voltage switches, gases with good dielectric properties and very high breakdown voltages are needed. Highly electronegative elements, e.g., halogens, are favored as they rapidly recombine with the ions present in the discharge channel. The halogen gases are highly corrosive. Other compounds, which dissociate only in the discharge pathway, are therefore preferred; sulfur hexafluoride, organofluorides (especially perfluorocarbons) and chlorofluorocarbons are the most common.

The breakdown voltage of gases is roughly proportional to their density. Breakdown voltages also increase with the gas pressure. Many gases have limited upper pressure due to their liquefaction.

The decomposition products of halogenated compounds are highly corrosive, hence the occurrence of corona discharge should be prevented.

Build-up of moisture can degrade dielectric properties of the gas. Moisture analysis is used for early detection of this.

Dielectric gases can also serve as coolants.

Vacuum is an alternative for gas in some applications.

Mixtures of gases can be used where appropriate. Addition of sulfur hexafluoride can dramatically improve the dielectric properties of poorer insulators, e.g. helium or nitrogen. Multicomponent gas mixtures can offer superior dielectric properties; the optimum mixtures combine the electron attaching gases (sulfur hexafluoride, octafluorocyclobutane) with molecules capable of thermalizing (slowing) accelerated electrons (e.g. tetrafluoromethane, fluoroform). The insulator properties of the gas are controlled by the combination of electron attachment, electron scattering, and electron ionization.

Atmospheric pressure significantly influences the insulation properties of air. High-voltage applications, e.g. xenon flash lamps, can experience electrical breakdowns at high altitudes.

* The density is approximate; it is normally specified at atmospheric pressure, the temperature may vary, though it is mostly 0 °C.

Warp3D. Warp3D was a project founded by Haage & Partner in 1998 that aimed to provide a standard API that would enable programmers to access, and therefore use, 3D hardware on the Amiga.

Its design was similar to that of both the Picasso96 graphics card drivers and operated in a similar fashion to the 3dfx Glide API, which provided a uniform and standardised way for programmers to create software for the 3D graphics cards that were available at the time.

It was hoped that the creation of this API would not only encourage the development and release of more 3D graphics cards, but also move away from the situation where a new piece of hardware had been developed with no software available to run on it. If the particular piece of software used the Warp3D API (enabled through a shared library), any current or newly developed hardware would be able to be used. Hyperion Entertainment developers created OpenGL subset called MiniGL sitting on top of Warp3D to ease porting of games such as Heretic II.

At time of its release, Warp3D provided significant speed increase over software rendering. Years later however, newer 3D APIs (e.g. TinyGL in MorphOS) offered better performance on the same hardware.

In 2014, it was announced that Warp3D was now jointly owned by British company A-EON Technology Ltd.  On April 1, 2015, A-EON Technology subsequently released Warp3D for RadeonHD (Southern Islands chipset).

In March 2016, A-EON Technology Ltd announced that they had developed the new Warp3D Nova featuring support for Shaders. Warp3D Nova was originally mentioned as planned complete rewrite and Shader-centric design in the AmigaOS 4.0 Feature List more than decade earlier. Development of the new release intentionally took some inspiration from this original Warp3D Nova plan. The pre-release version 1.15 was published on 1 May 2016 in the Enhancer Software package for AmigaOS 4. Apart from its name and being related to 3D graphics, Warp3D Nova has nothing in common with the original Warp3D.

Also in March 2016 A-EON Technology Ltd announced that Daniel Müßener / GoldenCode.eu had been hired to create an OpenGL ES 2 implementation on top of Warp3D Nova. The first public version 1.4 was released on 31 August 2016 as part of the Enhancer Software package version 1.1.

Running Requirements
Warp3D requires the following in order to work properly
 An AmigaOS compatible system with CyberGraphX or Picasso96, containing:
 At least a 68040 processor with FPU for AmigaOS versions predating 4.0
 A PowerPC CPU for AmigaOS 4.0+
 Optionally PowerPC supported on WarpOS
 Any of these graphics cards:
 CyberVision 3D
 CyberVision PPC
 BlizzardVision PPC
 Any 3Dfx Voodoo card
 ATI Radeon R100, R200 
 ATI RadeonHD Southern Islands graphics cards

It also requires 3D hardware to be present, and will not run with graphics cards that are 2D only, or AGA, ECS or OCS.

Other implementations

Alain Thellier created open source clone called Wazp3D. MorphOS included a Warp3D implementation known as Goa3D Graphics Library developed by Nicolas Sallin.

Ocean Therapy Solutions. Ocean Therapy Solutions (OTS) is a company owned by actor Kevin Costner. He acquired the company from the United States government for US$24 million in 1995.   The company specializes in developing centrifugal oil-water separators. After the Exxon Valdez oil spill in 1989, Costner wanted to find a new way to separate oil from water, so he acquired the company. He found it difficult to promote its products, until BP placed an order for several of the company's devices in the aftermath of the Deepwater Horizon oil spill.

OTS's largest machine, the V20, can clean up to  of oily water per day. On July 8, 2010, OTS reported it had 9 centrifuges deployed in the Gulf of Mexico, with 23 additional machines under construction and scheduled for shipment to Louisiana by the end of August 2010.

The machines developed by the company were of little commercial interest until the Deepwater Horizon oil spill, when BP took six of the machines for testing in late May 2010. On June 9, that order was expanded to 32 of the oil-water separation devices.

Lawsuit
Stephen Baldwin and Spyridon Contogouris (plaintiffs) had a joint agreement to market the technology. They filed a lawsuit in the Louisiana District Court claiming securities fraud and misrepresentation in the amount of $10.64 million. The suit claims that Costner held a meeting with BP without notifying plaintiffs. At that meeting, OTS sold BP $52 million worth of product, receiving an $18 million deposit. Costner is then alleged to have used portions of the deposit to buy out plaintiffs shares before they were made aware of the BP purchase, thus cutting them out of the profits from the $52 million sale. Baldwin and Contogouris allege they were misled by Costner into believing BP had no interest in the technology, thus persuading them to accept Costner's lowball offer for their shares. Plaintiffs receipts from their share sales totaled just under $2 million - $1.4 million to Baldwin and $500,000 to Contogouris. On June 15, 2012, the jury ruled in favor of Costner, giving Baldwin and Contogouris nothing.

Advanced Automotive Design. Advanced Automotive Design (AAD) is a South African automobile and kit car manufacturer located in Die Wilgers, Pretoria. The company was founded in 1995 by Brian Glover and Rhys Edwards. Shaka is a registered Trademark of the AAD.

Rhys Edwards lead the design and engineering of AAD. He had experience in constructing race cars and vehicles for the Armed Forces.

Vehicles
In 1997, they showed their first vehicle called Shaka Nynya on the South Florida International Auto Show. This was a concept car similar to the Plymouth Prowler. Sales began in 2000. Glover Designs Inc from Florida distributed the vehicles in the USA .  One source states that production ended in 2010.  In 2000 and 2002 one complete vehicle was built, in 2001 none and in 2003 two.

The model was a sports car.  It used a space frame made of tubes and had an open two-seater body made of fiberglass mounted on it.  The literature describes the vehicle as being in the style of a Lotus Seven but with a more modern body.  Another source describes it as having a similarity to the Plymouth Prowler.  The standard engine was a V8 engine from Oldsmobile with a displacement of 5700 cc, but another engine from Oldsmobile and a V6 engine from Buick are also known to have been used.  Another source mentions engines from Chevrolet.

The companies other model was the Shaka Giotto which was a coupe with a similar shape to the Nissan 300ZX.

Nano-tetherball sensor. The nano-tetherball sensor is one of newly discovered methods in detecting glucose in the human body.  The nano-tetherball sensor for glucose has attracted attention of diabetic medical community due to its methods and high sensitivity in performance. The machine’s name comes from the fact that its design is similar to a small cube-shaped tetherball.  Nano machines have been in the biosensor industry for more than two decades, and they have performed a number of different beneficial roles for diabetic patients. Despite the many opto/electronic mechanisms on the market, from a physical and chemical point of view, the nanomachine optical fiber provides many advantages over the other types.

These advantages include its remote in-situ or actual detection; its wavelength has the highest degree of selectivity, with high information competence and analysis with multi-channels of wide capacity for detecting reagents that are non-responsive in electrical structures.  The cubes rely on the tetherball structure and involve manipulation of tiny amounts of lasers in micro-channel using Nano-tetherballs. The Nano-tetherball process has the potential of being the most reliable in the accumulation of information. Medical statements that emphasize how the machine compares with other digital data storage and retrieval processes, to determine exactly how effective the machine is with processing the data detected and how to use said data. The information collected will be helpful for the formulation of treatments which are more practical than
other digital bio-optical machines provide.

Model

This fresh biosensor is more responsive than others in two very significant roles; glucose sensors need at least six times more glucose to produce an indicator, and the original sensor can gather an overindulgence of a wider variety of glucose application, meaning it can be used for number of functions. Much work has gone into developing the optimal electrode configuration to match biosensing needs. This structure is at times further functionalized to complete the biosensor fabrication process. A multi-wall platinum substrate, subsequently functionalized by oxidation, helps to allow the effectivity on the control of the glucose oxidase enzymes. The open ends of nanotubes, which are carboxylated (CNT), are used for the control of the enzymes and signaling detection monitor by the platinum substrate which gives the actual transduction platform. This glucose oxidase functionalized MWNT biosensor was used to detect various amounts of glucose. In devices such as these the CNTs play a dual role a substrate to attach biologically significant molecules and as the transducer
component of the biosensor.

Bharat Nirman. The Bharat Nirman Yojana was a flagship program launched in 2005 by the United Progressive Alliance (UPA) government under the leadership of then-Prime Minister Dr. Manmohan Singh. It was designed as a time-bound initiative to build and upgrade rural infrastructure in India, aiming to improve the quality of life in villages and boost rural development.

It comprises projects on irrigation, roads (Pradhan Mantri Gram Sadak Yojana), housing (Indira Awaas Yojana), electrification (Rajiv Gandhi Grameen Vidyutikaran Yojana), water supply and telecommunication connectivity.

Progress
By September 2007, significant progress was reported across its six components: Under the rural roads component, 48,215 km of roads were constructed to connect remote habitations. In housing, 36.81 lakh houses were built, progressing towards the target of 60 lakh. Drinking water initiatives focused on addressing contamination issues, covering 2,982 uncovered habitations and other affected areas. The irrigation segment aimed to create potential for 1 crore hectares, with a target of 28.50 lakh hectares for the fiscal year 2007-08. During the twelfth five-year plan, received a substantial budget allocation of 76,435 crore rupees from the Planning Commission in 2012.

The Pradhan Mantri Gram Sadak Yojana (PMGSY) was launched on 25 December 2000. The primary objective of PMGSY is to provide good quality all-weather roads in all the rural areas where urban-rural road connectivity is found to be very weak. All unconnected habitations with a population of more than 500 persons has been provided connectivity by 2007.

Sidney Waterworks and Electric Light Building. The Sidney Waterworks and Electric Light Building is a historic structure on the east side of Sidney, Ohio, United States.  Erected in 1873, the building is a former waterworks and power plant for the city.  This four-story brick building is the third-oldest waterworks in southwestern Ohio, preceded only by those in Cincinnati and Dayton.  After nearly thirty years of operation, the building was converted into a hydroelectric power plant: instead of pumping water to the city's residents, the building's machinery was used to operate a water wheel for the generation of electricity.

Built on a limestone foundation, the building's four floors have always been used for distinct purposes.  While the building's machinery was located on the lower two floors, the upper two floors were used for residential purposes.

In 1978, the Sidney Waterworks and Electric Light Building was listed on the National Register of Historic Places because of its historical and architectural significance.  As an early utility plant, the building is important in statewide history, and it is architecturally notable because of its western facade, which faces the Great Miami River.  Today, the entire structure is used as a house.

Liquid dielectric. A liquid dielectric is a dielectric material in liquid state. Its main purpose is to prevent or rapidly quench electric discharges. Dielectric liquids are used as electrical insulators in high voltage applications, e.g. transformers, capacitors, high voltage cables, and switchgear (namely high voltage switchgear). Its function is to provide electrical insulation, suppress corona and arcing, and to serve as a coolant.

A good liquid dielectric should have high dielectric strength, high thermal stability and inertness against the construction materials used, non-flammability and low toxicity, good heat transfer properties, and low cost.

Liquid dielectrics are self-healing; when an electric breakdown occurs, the discharge channel does not leave a permanent conductive trace in the fluid.

The electrical properties tend to be strongly influenced by dissolved gases (e.g. oxygen or carbon dioxide), dust, fibers, and especially ionic impurities and moisture. Electrical discharge may cause production of impurities degrading the dielectric's performance.

Some examples of dielectric liquids are transformer oil, perfluoroalkanes, and purified water.
