PTC rubber. PTC rubber is a silicone rubber which conducts electricity with a resistivity that increases exponentially with increasing temperature for all temperatures up to a temperature where the resistivity grows to infinity. Above this temperature the PTC rubber is an electrical insulator. PTC rubber is made from polydimethylsiloxane (PDMS) loaded with carbon nanoparticles. PTC stands for Positive temperature coefficient.

Properties
If the electric field strength inside the material is large enough (typically larger than 30 V/mm), the carbon nanoparticles trigger a quantum mechanical tunneling effect current to flow through the material. The contribution from a large number of small tunneling effect currents can add up to macroscopic currents in the range of amperes.
The quantum mechanical tunneling effect inside the material is highly temperature dependent. The current decreases exponentially with increasing temperature. This means that the resistivity of the material grows exponentially with increasing temperature. At a specific temperature the quantum mechanical tunneling effect current ceases. At temperatures higher than this the PTC rubber is an electrical insulator and no electrical current can flow through it. This temperature can be adjusted between 0 and +80 °C during the production of the PTC rubber. Hence, PTC rubber is a PTC material with very strong PTC characteristics. In fact, PTC rubber has the strongest PTC effect of all known materials, and over a wide temperature range. It has PTC properties for all temperatures.

Applications
The PTC rubber can be rolled into thin sheets and laminated with copper. The copper is in turn connected to a voltage to provide the electrical field inside the material necessary to trigger the tunneling effect. The sheets can be formed into any shape and size.

PTC rubber sheets can be used as thin flexible PTC heaters. These heaters will provide high power when they are cold and rapidly heat up themselves to a constant temperature and remain there virtually unaffected by changes in the ambient conditions. They can be powered with any voltage between 5 and 230 V, AC or DC.

The PTC rubber material is a self-regulating heater. It produces the same amount of heat in each point of the heater as is conducted and radiated away from the heater to the object it is attached to, and its surroundings. It is in constant thermal equilibrium with the environment, point by point. A measure of the power produced by the heater is actually a measurement of the heat transfer between the heater and the object. Hence, it can be used as a heat transfer sensor.

Cécile Réal. Cécile Réal (; born 29 November 1973) is a French biomedical engineer and business executive. In 2012, as president of Endodiag, she won the Cartier Women's Initiative Award for developing tools to diagnose and treat endometriosis.

Biography

Réal, who studied biomechanical engineering at the University of Technology of Compiègne (1991–1996) also has a master's degree in business and technology management from Lappeenranta University of Technology in Finland. In 1999, when she was only 25, she founded and ran Bioprofile which produced orthopaedic implants with pyrocarbon. She sold the company in 2007, deeming it important to allow more experienced players to bring the products to market. While serving as chief operating officer at Ariana Pharma (2008–2010), a company specializing in biomarkers, in 2009 she founded Fluoptics which handles fluorescence imaging for cancer surgery. In 2011, she co-founded Endodiag where she is CEO.

Endodiag specializes in endometriosis which occurs when small pieces of the lining of the womb migrate to other parts of the body. The cells cause pain and can lead to infertility. It is not unusual for diagnosis to take up to nine years. The company is developing methods to improve diagnosis with tools such as EndoGram, based on biopsy, and EndoDiag, relying on a simple blood test.

In 2016, Réal was the speaker for a TEDx Talk on "Endometriosis-The Mystery Disease of Women."

William Allan (trade unionist). William Allan (August or September 1813 – 15 October 1874) was a British trade unionist.

Born in Ulster, Allan grew up in Glasgow, working in a cotton mill from the age of twelve, then later serving an engineering apprenticeship.  However, before completing the apprenticeship, he married and moved to Liverpool, soon finding work with the Grand Junction Railway Company.  He later moved to Crewe to further his career, and while there joined the Manchester Society of Mechanics and also the Journeymen Steam Engine and Machine Makers' Friendly Society ("Old Mechanics"), two early trade unions.

In 1847, Henry Selsby, the secretary of the Old Mechanics, was arrested for supporting engineers who were on strike, and the following year he resigned, with Allan elected to take his place.  Allan was in favour of union amalgamations, and he worked with William Newton to bring together several branches of other unions to form the Amalgamated Society of Engineers, the first example of what became known as a "New Model Union".  Some branches of the Old Mechanics did not join, but Allan persevered and by the end of 1851 had brought membership up to over 10,000.

Allan was also prominent in the national trade union movement.  He instigated the formation of the London Trades Council, and was close to the members of the "Junta".  He joined the Reform League, attended the first Conference of Amalgamated Trades and first Co-operative Congress, was the treasurer of the Labour Representation League, and although he was initially suspicious of the Trades Union Congress, he soon came to support it, becoming treasurer in 1871.  He also became chair of the Bee-Hive newspaper for the labour movement in 1870.

During the 1870s, Allan gradually became less active due to suffering from Bright's disease, but he remained in his posts until his death in 1874.

Nano aquarium. Nano aquariums are aquariums with the emphasis on small scale inhabitants inside smaller sized aquariums. They can be either freshwater nano aquariums or saltwater nano aquariums. Nano fish species are chosen from any smaller sized species of tropical fish. Other possible inhabitants are freshwater and seawater shrimps. Any plants for a nano aquarium also have to be of the smaller species.

The marine nano aquarium is more difficult to maintain than the nano freshwater aquarium.

DB Class 611. The DBAG Class 611 is a two car, tilting, diesel multiple unit operated by Deutsche Bahn for fast regional rail services on unelectrified lines.

General information 

Class 611, successor to the DB Class 610, was developed using tilting systems from German military technology in favour of the Hydraulic Fiat systems used by its predecessor Because of environmental concerns over the potential hazards of leaking hydraulic fluid an electrically actuated option based on equipment used to keep the guns of tanks level while traversing uneven terrain was used. The Class 611 suffered teething troubles following its entry into service just two years after the contract was awarded and was largely considered a failure. However, 40 are still in use as of November 2015.

Tilting technology issues 
The trains came into service in 1996 and by March 1997 the first problems with the tilting technology occurred. The Federal Railway Authority limited the Class 611 to 120 km/h and required the tilting technology to be disabled, this was only reversed in May 1999 when they were satisfied the issues had been resolved. The tilting was disabled again in August 2004 when cracks were found in the 611's successors wheel sets, the DBAG Class 612, during ultrasound examinations of the axles. Tilting was disabled and speed limits on curved tracks were reduced until 2006 when the problematic wheel sets were replaced. However further issues were experienced and in October 2009, the tilting technology was disabled once again. Since April 3, 2011, Class 611 trainsets have been used in Baden-Württemberg with tilting technology enabled once more.
