In linguistics, a distinctive feature is the most basic unit of phonological structure that may be analyzed in phonological theory.
Distinctive features are grouped into categories according to the natural classes of segments they describe: major class features, laryngeal features, manner features, and place features. These feature categories in turn are further specified on the basis of the phonetic properties of the segments in question. Since the inception of the phonological analysis of distinctive features in the 1950s, features traditionally have been specified by assigning them binary values to signify that the segment being described by the feature either possesses that phonetic property or it does not. Therefore, a positive value, [+], denotes the presence of a feature, while a negative value, [?], indicates its absence. However, in recent developments to the theory of distinctive features, phonologists have proposed the existence of single-valued features. These features, called univalent or privative features, can only describe the classes of segments that are said to possess those features, and not the classes that are without them.

Week News Abstract For SFP Series in 10GTEK:Pests and weeds
The cotton industry relies heavily on chemicals, such as herbicides, fertilizers and insecticides, although a very small number of farmers are moving toward an organic model of production, and organic cotton products are now available for purchase at limited locations. These are popular for baby clothes and diapers. Under most definitions, organic products do not use genetic engineering.
Historically, in North America, one of the most economically destructive pests in cotton production has been the boll weevil. Due to the US Department of Agriculture's highly successful Boll Weevil Eradication Program (BWEP), this pest has been eliminated from cotton in most of the United States. This program, along with the introduction of genetically engineered Bt cotton (which contains a bacterial gene that codes for a plant-produced protein that is toxic to a number of pests such as cotton bollworm and pink bollworm), has allowed a reduction in the use of synthetic insecticides.
Other significant global pests of cotton include the pink bollworm, Pectinophora gossypiella; the chili thrips, Scirtothrips dorsalis; the cotton seed bug, Oxycarenus hyalinipennis; the tarnish plant bug, Lygus lineolaris; and the fall armyworm, Spodoptera frugiperda.

Week News Abstract For SFP Series in 10GTEK:After the Reform Act
The Reform Act extended the boundaries of the constituency, bringing in the neighbouring townships of Tanshelf, Monkhill, Knottingley, Ferrybridge and Carleton, as well as Pontefract Castle and Pontefract Park which had previously been excluded. This doubled the population to just over 10,000, in 4,832 houses.
In 1872, Pontefract was the first British constituency to hold a parliamentary election by secret ballot, at a by-election held shortly after the Act ending the old practice of open voting had come into effect. There was considerable interest in the outcome, many observers believing that support for the parties might be drastically different once voters were able to make their choice in secret; but in the event the shares of the vote were much as they had been at the previous general election. Hugh Childers was re-elected on 15 August 1872 following his appointment as Chancellor of the Duchy of Lancaster. The original ballot box, sealed in wax with a liquorice stamp, is held at Pontefract museum.[1]
In the third Reform Act, which came into effect at the general election of 1885, Pontefract's representation was reduced from two members to one, though the boundaries remained essentially unchanged. In 1918, Pontefract became a county constituency, and its boundaries were extended to cover a much wider area - Pontefract itself, the towns of Knottingley and Goole, and the Pontefract and Goole rural districts.
At the 1950 general election, Pontefract regained its borough status, being redrawn as a wholly urban constituency, consisting of Pontefract, Castleford and Featherstone. From February 1974, the constituency was renamed Pontefract and Castleford, although its composition remained unchanged.

Week News Abstract For SFP Series in 10GTEK:Moraine
A moraine is any glacially formed accumulation of unconsolidated glacial debris (soil and rock) which can occur in currently glaciated and formerly glaciated regions, such as those areas acted upon by a past glacial maximum. This debris may have been plucked off a valley floor as a glacier advanced or it may have fallen off the valley walls as a result of frost wedging or landslide. Moraines may be composed of debris ranging in size from silt-sized glacial flour to large boulders. The debris is typically sub-angular to rounded in shape. Moraines may be on the glacier’s surface or deposited as piles or sheets of debris where the glacier has melted. Moraines may also occur when glacier- or iceberg-transported rocks fall into a body of water as the ice melts.

Week News Abstract For SFP Series in 10GTEK:Film
A film, also called a movie or motion picture, is a series of still or moving images. It is produced by recording photographic images with cameras, or by creating images using animation techniques or visual effects. The process of filmmaking has developed into an art form and industry.
Films are cultural artifacts created by specific cultures, which reflect those cultures, and, in turn, affect them. Film is considered to be an important art form, a source of popular entertainment and a powerful method for educating – or indoctrinating – citizens. The visual elements of cinema give motion pictures a universal power of communication. Some films have become popular worldwide attractions by using dubbing or subtitles that translate the dialogue into the language of the viewer.
Films are made up of a series of individual images called frames. When these images are shown rapidly in succession, a viewer has the illusion that motion is occurring. The viewer cannot see the flickering between frames due to an effect known as persistence of vision, whereby the eye retains a visual image for a fraction of a second after the source has been removed. Viewers perceive motion due to a psychological effect called beta movement.
The origin of the name "film" comes from the fact that photographic film (also called film stock) has historically been the primary medium for recording and displaying motion pictures. Many other terms exist for an individual motion picture, including picture, picture show, moving picture, photo-play and flick. A common name for film in the United States is movie, while in Europe the term film is preferred. Additional terms for the field in general include the big screen, the silver screen, the cinema and the movies.

Week News Abstract For SFP Series in 10GTEK: Early life
Prince Maurice was born on 3 October 1891. He was given the name Maurice after his father Prince Henry of Battenberg and the great-grandfather, Count Maurice von Hauke, Victor after his grandmother the Queen, and Donald in honour of Scotland, as he was born at Balmoral Castle. His father was Prince Henry of Battenberg, the son of Prince Alexander of Hesse and by Rhine and Julie Therese née Countess Hauke. His mother was Princess Henry of Battenberg (née The Princess Beatrice of the United Kingdom), the fifth daughter and the youngest child of Queen Victoria and Albert, Prince Consort.
As his father was the child of a morganatic marriage, Prince Henry of Battenberg took his style of Prince of Battenberg from his mother, Countess Julia Hauke who was created Princess of Battenberg in her own right. As such, Maurice was styled as His Serene Highness Prince Maurice of Battenberg from birth. In the United Kingdom, he was styled His Highness Prince Maurice of Battenberg under a Royal Warrant passed by Queen Victoria in 1886.
The youngest of his four siblings, Maurice most resembled his father, who died when the Prince was only four, the same age his mother was when her own father died. He was his mother's favourite out of his brothers. He was educated at Lockers Park Prep School in Hertfordshire.
His elder sister Victoria Eugenie of Battenberg, married Alfonso XIII of Spain and was Queen Consort of Spain between 1906 and 1931.

Week News Abstract For SFP Series in 10GTEK： Interactive storytelling Geography
Interactive Storytelling [IS] is a form of digital entertainment in which users create or influence a dramatic storyline through actions, either by issuing commands to the story's protagonist, or acting as a general director of events in the narrative. Interactive storytelling is a medium where the narrative, and its evolution, can be influenced in real-time by a user.[1]
Unlike interactive fiction, there is an open debate about nature of the relationship between interactive storytelling with computer games. Crawford states that "Interactive storytelling systems are not "Games with Stories"",[2] whereas much research in the community focuses on applications to computer games. There are several key issues in interactive storytelling, for example: how to generate stories which are both interesting and coherent; and how to allow the user to intervene in the story, without violating any rules of the genre.[3]From north south the delta is approximately 160 km in length. From west to east it covers some 240 km of coastline. The delta is sometimes divided into West and East sections, with the Nile dividing into two main distributaries, the Damietta and the Rosetta, flowing into the Mediterranean at port cities with the same name. In the past, the delta had several distributaries, but these have been lost due to flood control, silting and changing relief. One such defunct distributary is Wadi Tumilat. The Suez Canal runs to the east of the delta, entering the coastal Lake Manzala in the north-east of the delta. To the north-west are three other coastal lakes or lagoons: Lake Burullus, Lake Idku and Lake Maryut
The Nile is considered to be an "arcuate" delta (arc-shaped), as it resembles a triangle or lotus flower when seen from above. The outer edges of the delta are eroding, and some coastal lagoons have seen increasing salinity levels as their connection to the Mediterranean Sea increases. Since the delta no longer receives an annual supply of nutrients and sediments from upstream due to the construction of the Aswan High Dam, the soils of the floodplains have become poorer, and large amounts of fertilizers are now used. Topsoil in the delta can be as much as 70 feet (21 m) in depth.
