Regen SW. Regen is a not-for-profit organisation which promotes renewable energy and energy efficiency across the UK.

The organisation works with industry, communities and the public sector to change the way we generate, supply and use energy. Its functions are to help towards the development of renewable energy in the South West, by giving independent advice to decision makers, assisting independent developers, investing in trial microgeneration or utility scale projects and informing the public about renewable energy.

Regen SW was funded by the South West of England Regional Development Agency until that agency was abolished in March 2012. Since then, funding has come from subscription-based membership and partner organisations, advisory work, and grant funding.

Its chief executive, Merlin Hyman, was previously director of the Environmental Industries Commission, where he worked to help British companies in the rapidly growing worldwide market for low-carbon products and services.  He sits on the government’s Shared Ownership Taskforce, working to provide communities with a right to buy into commercial projects, and the National Solar Strategy group.

Maitighar Mandala. The Maitighar Mandala () is a symbolic monument located in the heart of Kathmandu, Nepal. It is an island at the intersection of roads from Thapathali, New Baneshwor, Bhadrakali and at the southeast corner of Singhadurbar, the administrative centre of Nepal. It forms an important landmark in the beautification of Kathmandu city and a master piece of art depicting Buddhist relics. It also marks the initiation mark stone of one of the major highways of Nepal, Araniko Highway, that links Nepal with China.

History 
The Mandala was built in 2001 for the 11th SAARC summit in Nepal to showcase Nepali culture after clearing many multi-story buildings during the tenure of mayor Keshav Sthapit.

Etymology 
The name "Maitighar" literally means the "Parental Home' of the married women. Actually, there was a movie theater in today's Maitighar in the past, and a classic Nepal film, Maithighar (1966) was run for about a year. As there was a large poster depicting the name of the movie, people started calling the place as Maitighar.

The native name of the monument in Newar language is Fibwa Khya ().

Symbolism 
The Mandala was designed to be in the form of a series of concentric circles. The outer-most has 32 vajras, the one next to it has 16 lotus petals and the inner has 32 garlands. Various colors on the Mandala (blue background, black, orange, and blue circles)  symbolize man's characteristics - too much of one would result in an imbalanced temperament. Black stands for  Krodh (anger), orange for Prem (love) and blue for Karuṇā (compassion). At the four corners of the mandala are symbols of the Ashtamangal.

Significance 
During the Nepalese Civil War, peace advocates gathered at the Mandala to show solidarity for peace and against violence.

The government declaring the Mandala area a protest-free-site.

Maintenance 
By 2010, the Mandala artwork fell into disrepair. In 2011, the Agriculture Development Bank, Nepal pledged to devote resources to restore the Mandala. The Mandala got a face-lift for the 18th SAARC summit along with the overall enhancement of roads in Kathmandu.

Alpe Gera Dam. The Alpe Gera Dam is a gravity dam on the Cormor River in a lateral valley of Valmalenco  northeast of Sondrio in the Lombardy region of Italy. It is  tall and supports a 35 MW hydroelectric power station.

The dam was constructed between 1958 and 1964 and is best known for the concrete placement techniques used during its construction. Instead of concrete being poured into conventional monoliths, it was poured in layers with a lean mix. Next, the concrete was settled with immersed vibrators and then contraction joints were cut into the layer. These methods were not only cost-saving but instrumental in the development of roller-compacted concrete in dam construction.

Imogolite. Imogolite is an aluminium silicate clay mineral with the chemical formula . It occurs in soils formed from volcanic ash and was first described in 1962 for an occurrence in Uemura, Kumamoto prefecture, Kyushu Region, Japan. Its name originates from the Japanese word , which refers to the brownish yellow soil derived from volcanic ash. It occurs together with allophane, quartz, cristobalite, gibbsite, vermiculite and limonite.

Imogolite consists of a network of nanotubes with an outer diameter of ca. 2 nm and an inner diameter of ca. 1 nm. The tube walls are formed by continuous  (gibbsite) sheets and orthosilicate anions ( groups). Owing to its tubular structure, natural availability, and low toxicity, imogolite has potential applications in polymer composites, fuel gas storage, absorbents, and as a catalyst support in chemical catalysis.

Robert H. Widmer. Robert Henry Widmer (May 17, 1916 – June 20, 2011) was an American aeronautical engineer who specialized in designing aircraft for the military. He spent his career working for  Convair which became General Dynamics, then Lockheed, and then Lockheed Martin. His feisty personality and at times insubordinate attitude at one time led company leaders to strongly consider firing him. However, his brilliance at envisioning and designing desirable aircraft years before there was even a market for them led to his appointment as Vice President for science and engineering for all of General Dynamics.

Born in Hawthorne, New Jersey, Widmer earned degrees from Rensselaer Polytechnic Institute and the California Institute of Technology. He began his career working for the California division of Convair, initially as a designer of marine aircraft. He eventually joined the company's main branch in Fort Worth, Texas, where he notably designed the Convair B-58 Hustler which was the first United States Air Force's bomber capable of Mach 2. He went on to lead the design teams for the General Dynamics F-111 Aardvark and the General Dynamics F-16 Fighting Falcon. In 1983 he was awarded the Reed Aeronautics Award by the American Institute of Aeronautics and Astronautics. The award credited him with leading the design of four major Air Force aircraft, the B-36, B-58, F-111, and F-16, and for "pioneering the eras of supersonic cruise and fly-by-wire computerized flight control".  In 1962, he was awarded the Spirit of St. Louis Medal by the American Society of Mechanical Engineers for his work on the B-58. In 2007, he was inducted into the Rensselaer Alumni Hall of Fame.

Widmer died in Fort Worth, Texas in 2011 at the age of 95.

Rajendra Setu. Rajendra Setu, or Simaria Bridge, is a bridge across the Ganges that was the first to link the northern and southern portions of the state of Bihar. The location of the bridge was based on the work of M. Visvesvaraya, who was more than 90 years old at the time. In a wheelchair, he visited the bridge site on the special request of Bihar's chief minister, Shri Krishna Sinha. It was the first bridge over the Ganges to be built in independent India.

The foundation stone of this bridge was laid by Dr Rajendra Prasad on 26 February 1956 in the seventh year of India's independence.

The road-cum-rail bridge near Hathidah in Patna district and Simaria in Begusarai district was inaugurated in 1959 by Jawaharlal Nehru, prime minister of India, and Shri Krishna Sinha. The bridge was constructed by Braithwaite, Burn & Jessop Construction Company. It is about  long and carries a two-lane road and a single-line railway track.

A new bridge, carrying the four-lane NH 31 and double-track rail, 25 metres upstream from the existing rail and road bridge, was planned in 2011.

The construction of the new parallel double-line railway bridge was inaugurated by prime minister Narendra Modi on 12 March 2016. The new 1.9 km railway bridge was supposed to be operational by February 2021, but is now expected to be operational by 2024. The contract for construction of the new bridge was awarded to M/s AFCONS Infrastructure Ltd by the Indian Railway Construction International Limited (IRCON) on an EPC contract basis. Construction has also started on a new six-lane road bridge, which has a span of 34 metres, parallel to it, which is supposed to become operational by December 2024.

Nanochannel glass materials. Nanochannel glass materials are an experimental mask technology that is an alternate method for fabricating nanostructures, although optical lithography is the predominant patterning technique.

Nanochannel glass materials are complex glass structures containing large numbers of parallel hollow channels. In its simplest form, the hollow channels are arranged in geometric arrays with packing densities as great as 1011 channels/cm2. Channel dimensions are controllable from micrometers to tens of nanometers, while retaining excellent channel uniformity. Exact replicas of the channel glass can be made from a variety of materials. This is a low cost method for creating identical structures with nanoscale features in large numbers.

Characteristics
These materials have high density of uniform channels with diameters from 15 micrometres to 15 nanometers. These are rigid structures with serviceable temperatures to at least 300 °C, with potential up to 1000 °C. Furthermore, these are optically transparent photonic structures with high degree of reproducibility.

Applications
These can be used as a material for chromatographic columns, unidirectional conductors, Microchannel plate and nonlinear optical devices. Other uses are as masks for semiconductor development, including ion implantation, optical lithography, and reactive ion etching.

Radium, and Other Radioactive Substances. Radium, and Other Radio-active Substances; Polonium, Actinium, and Thorium is a book published in 1903 by William Joseph Hammer, when he was about 50 years old. The book is the text of a lecture delivered at a meeting of the American Institute of Electrical Engineers. The title of the lecture was "Radium and other radioactive substances with a consideration of phosphorescent and fluorescent substances. The properties and applications of selenium and the treatment of disease by the ultra violet light". The lecture was augmented by 38 lantern slides, which are reproduced in the book.

Subjects

Radioactivity
In addition to the matters implied by the title of the lecture (radium, polonium, actinium and thorium), Hammer discusses:
 The work of Pierre and Marie Curie, Dewar, Roentgen, Henri Becquerel, Rutherford, J. J. Thomson and Kelvin
 Uranium
 Ores of various radioactive materials
 Alpha, beta, gamma and X-rays forms of radiation, including radiographs of mice made by the latter, and experiments into the lethal effects of X-rays and radioactive sources

Selenium
There are 21 pages devoted to "The properties and applications of selenium", including the use of its changing electrical resistance in different light levels. A quantitative measurement of an eclipse of the sun, by means of a selenium based sensor, is reported. Use of selenium in a "radiophone" devised by Alexander Graham Bell around 1883 is described. (Bell used the sound waves to be transmitted to vibrate a mirror. A beam of light bounced off the mirror onto a selenium object. The variation in the light falling on the sensor translated to a varying electrical signal which could be transmitted, then turned back into vibrations in the air.) Ernst Ruhmer's photographophone is described. It recorded sound similarly to a phonograph, but the sound waves were used, via a selenium cell, to vary the brightness of a beam falling on a moving strip of photographic film. Ruhmer is also credited with using a selenium cell to turn off the lights of maritime navigation buoys during daylight hours, thus conserving the gas they burned.

Light
The book concludes with nine pages concerning the work of Niels R Finsen of Copenhagen, who was treating various diseases with light. Hammer notes that for a time, "Finsen's work received little credence... but he persisted... to-day the world rings with his praises." It is claimed that by 1903, Finsen's work was approved of "In England by Queen Alexandra, and in Russia by her sister, the Czarina, they both investigating the system while visiting their father, the King of Denmark." There is even a claim that Finsen was able to spare smallpox victims from scarring by keeping them in a room with red glass windows while the disease went through certain stages.

Wittman DFA. The Wittman DFA aka Little Bonzo is a homebuilt racing aircraft designed to compete in midget racing.

Development
Steve Wittman had started air racing in 1926 using various aircraft. In March 1931, he designed his own purpose-built aircraft in Oshkosh, Wisconsin, the Wittman Chief Oshkosh. After World War II, a new class of Midget air racing was formed with Wittmans efforts. Wittman re-engined "Chief Oshkosh" and renamed it "Bonzo". After several successful races in Cleveland in 1948, a cleaner sister ship "Little Bonzo" was built. The name is a reference to Wittman's much larger racer, the Wittman D-12 Bonzo.

Design
The Wittman DFA is a mid-winged conventional geared aircraft built from a welded steel tube fuselage with aircraft fabric covering and wooden wing construction. The DFA differs slightly from Bonzo with a smaller tail surface, a longer tail and a larger canopy.
In 1968, the engine was replaced with a Continental O-200 to compete under new race rules.

Operational history

Steve Wittman and Bill Brennand alternated flying "Buster" and "Little Bonzo". The aircraft was never transported by trailer and was instead always flown to events, where Wittman would perform aerobatics between heats in his racing aircraft.
1948 National Air Races - Cleveland pilot Wittman placed second.
1949 Continental Trophy races - first place
1950 Rebat Trophy - first place
1951 Rebat Trophy - first place
1952 Continental Trophy races - first place
1964 Reno Formula One Championship - second place 
1973 Goodyear race - the last competitive race for Little Bonzo.
