Fluoromethylidyne
Fluoromethylidyne is not a stable chemical species but a metastable radical containing one highly reactive carbon atom bound to one fluorine atom with the formula CF. The carbon atom has a lone-pair and a single unpaired (radical) electron in the ground state.

Ground-state fluoromethylidyne radicals can be produced by the ultraviolet photodissociation of dibromodifluoromethane at 248 nanometer wavelength.

It readily and irreversibly dimerises to difluoroacetylene, also known as difluoroethyne, perfluoroacetylene, or di- or perfluoroethylyne. Under certain conditions it can hexamerise to hexafluorobenzene.

Difluoroacetylene
Difluoroacetylene is a compound of carbon and fluorine having molecular formula C2F2. A linear molecule, its two carbons are joined by a triple bond and have terminal fluorines: F−C≡C−F. The molecule is the perfluorocarbon analog of acetylene, C2H2. Preparation of difluoroacetylene is difficult, with danger of explosions and with low yields. Nevertheless, the compound has been made, isolated, and characterized by various spectroscopical methods (MS, NMR, Photoelectron- and IR spectroscopy). The compound is of interest as a precursor to fluoropolymers containing double bonds, analogous to polyacetylene.

Difluoroacetylene is stable in the gaseous phase under low pressure. At liquid nitrogen temperature, it is slowly changing to tetrafluorobutatriene, most likely through an intermediate of difluorovinylidene.
Tell England (film)
Tell England is a 1931 British drama film directed by Anthony Asquith and Geoffrey Barkas and starring Fay Compton, Tony Bruce and Carl Harbord. It is based on the 1922 novel Tell England by Ernest Raymond which featured two young men joining the army, and taking part in the fighting at Gallipoli. Both directors had close memories of Gallipoli, as did Fay Compton's brother, Compton Mackenzie. Asquith's father H. H. Asquith had been Prime Minister at the time of the Gallipoli Landings, a fact which drew press attention to the film, while Barkas had fought at Suvla Bay in the Gallipoli campaign.

In the United States it was released under the alternative title The Battle of Gallipoli.

Suvla
Suvla (Greek: Σούβλα, "spit") is a bay on the Aegean coast of the Gallipoli peninsula in European Turkey, south of the Gulf of Saros.

On 6 August 1915, it was the site for the Landing at Suvla Bay by the British IX Corps as part of the August Offensive during the Battle of Gallipoli. The landing and others at various points along the peninsula were designed to capture the peninsula from Turkish troops defending it, and to open the Dardanelles Straits to Allied warships, thus facilitating a planned naval attack on Constantinople (Istanbul). The Gallipoli campaign ended in failure and high casualties for the Allied side, which included numbers of Australian, New Zealand, Indian, Irish, French, and Newfoundland troops.

The area is notable for viticulture and winemaking. The well-known wine producer "Suvla" is located here.
Bioenergy village
A bio-energy village is a regionally oriented concept for the use of renewable energy sources in rural areas. The system uses biomass from local agriculture and forestry in a biogas powerplant to meet the complete energy requirements of a village, such as electricity and district heating.

These villages tend to be self-powered and independent from external grids, despite being connected to overland grids for feeding surplus energy. The term "bio-energy village" refers to a dependency on fresh biological material as a source of energy only whereas an "ecovillage" includes a variety of networks.

Examples of such villages are Jühnde near Göttingen, Mauenheim near Tuttlingen and Bollewick near Berlin in Germany.

Biomass
Biomass is material produced by the growth of microorganisms, plants or animals. Beyond this general definition, there are differences in how the term is used and applied depending on industry or subject-matter norms. For example, it may be more narrowly defined as just plant matter, or as a combination of plant and animal matter.

The movement attracted not only poets, musicians, and artists (such as Umberto Boccioni, Giacomo Balla, Fortunato Depero, and Enrico Prampolini) but also a number of architects. A cult of the Machine Age and even a glorification of war and violence were among the themes of the Futurists; several prominent futurists were killed after volunteering to fight in World War I. The latter group included the architect Antonio Sant'Elia, who, though building little, translated the futurist vision into an urban form.

George Roussas
George Gregory Roussas (born June 29, 1933) is a Greek-American professor emeritus in statistics at University of California, Davis. He is noted for his contributions in asymptotic statistics and stochastic processes.

Asymptotic theory (statistics)
In statistics, asymptotic theory, or large sample theory, is a framework for assessing properties of estimators and statistical tests. Within this framework, it is often assumed that the sample size n may grow indefinitely; the properties of estimators and tests are then evaluated under the limit of n → ∞. In practice, a limit evaluation is considered to be approximately valid for large finite sample sizes too.
Belgian railway line 59
The Belgian railway line 59 is a railway line in Belgium connecting Antwerp with Ghent. It was opened between 1844 and 1847. Until 1970, the eastern terminus of the railway was a station on the left bank of the river Scheldt, opposite the city centre of Antwerp. Since 1970, the railway is connected to Antwerp central station by a rail tunnel under the Scheldt. The total length of the line between Antwerpen-Berchem and Gent-Dampoort (the section between Gent-Dampoort and Gent-Sint-Pieters is part of line 58 Ghent – Eeklo) is 55.8 km.

Glossary of rail transport terms
Rail transport terms are a form of technical terminology applied to railways. Although many terms are uniform across different nations and companies, they are by no means universal, with differences often originating from parallel development of rail transport systems in different parts of the world, and in the national origins of the engineers and managers who built the inaugural rail infrastructure. An example is the term railroad, used (but not exclusively) in North America, and railway, generally used in English-speaking countries outside North America and by the International Union of Railways. In English-speaking countries outside the United Kingdom, a mixture of US and UK terms may exist.

Various terms, both global and specific to individual countries, are listed here. The abbreviation "UIC" refers to terminology adopted by the International Union of Railways in its official publications and thesaurus.

Grande Riviere
Grande Riviere is a village on the north coast of Trinidad located between Toco and Matelot.  The area was originally settled by immigrants from Venezuela and Tobago who cultivated cacao and subsistence crops.  After falling cocoa prices in the 1920s and expanding pest problems caused the collapse of the cocoa industry, Grande Riviere went into a decline which continued until the development of ecotourism.  Between 1931 and 2000 the population of Grande Riviere fell from 718 to 334.

Grande Riviere is one of the more remote settlement in Trinidad and Tobago.  It is 60 kilometres from Sangre Grande and 100 km from the capital Port of Spain.  It is accessible via a single paved road which runs from Toco to its east and is separated from the rest of the island by the hills of the Northern Range.

Barry Island
Barry Island (Welsh: Ynys y Barri) is a district, peninsula and seaside resort, forming part of the town of Barry in the Vale of Glamorgan, South Wales. It is named after the 6th century Saint Baruc. Barry's stretch of coast, on the Bristol Channel, has the world's second highest tidal range of 15 metres (49 ft), second only to the Bay of Fundy in Nova Scotia, Atlantic Canada.

The peninsula was an island until the 1870s when it was linked to the mainland as the town of Barry expanded. This was partly due to the opening of Barry Docks by the Barry Railway Company. Established by David Davies, the docks now link up the gap which used to isolate Barry Island.

Although Barry Island used to be home to a Butlins Holiday Camp, it is now known more for its beach and Barry Island Pleasure Park. It was used as a setting of the BBC TV shows Gavin & Stacey and Being Human.

Seaside resort
A seaside resort is a city, town, village, or hotel that serves as a vacation resort and is located on a coast. Sometimes the concept includes an aspect of an official accreditation based on the satisfaction of certain requirements such as in the German Seebad. Where a beach is the primary focus for tourists, it may be called a beach resort.
