Natural rubber

Natural rubber, also called India rubber or caoutchouc, as initially produced, consists of polymers of the organic compound isoprene, with minor impurities of other organic compounds plus water. Malaysia is a leading producer of rubber. Forms of polyisoprene that are used as natural rubbers are classified as elastomers. Natural rubber is used by many manufacturing companies for the production of rubber products. Currently, rubber is harvested mainly in the form of the latex from certain trees. The latex is a sticky, milky colloid drawn off by making incisions into the bark and collecting the fluid in vessels in a process called "tapping". The latex then is refined into rubber ready for commercial processing. Natural rubber is used extensively in many applications and products, either alone or in combination with other materials. In most of its useful forms, it has a large stretch ratio and high resilience, and is extremely waterproof.

Uses

Compared to vulcanized rubber, uncured rubber has relatively few uses. It is used for cements; for adhesive, insulating, and friction tapes; and for crepe rubber used in insulating blankets and footwear. Vulcanized rubber, on the other hand, has numerous applications. Resistance to abrasion makes softer kinds of rubber valuable for the treads of vehicle tires and conveyor belts, and makes hard rubber valuable for pump housings and piping used in the handling of abrasive sludge.

Rubber (2010 film)

Rubber is a 2010 French independent dark comedy film about a tire that comes to life and kills people with its psychic powers. It was directed and written by Quentin Dupieux. The film was shown at the Cannes Film Festival in 2010. The film received positive reviews from critics, but it was a box office failure, grossing only US $100,370 on its US $500,000 budget.

Plot

A group of people in a California desert are gathered to watch a "film". A sheriff, Chad (Stephen Spinella), points out that many moments in cinema happen for "no reason", that life is full of this "no reason", and that "this film" (presumably a dual reference to both the "film" to be watched by the assembled group and Rubber itself) is an homage to "no reason".

An accountant (Jack Plotnick) then passes out binoculars to the group and rides off on a bicycle. The spectators then start looking through their binoculars into the distance, waiting for the "film" to start. Throughout the film, this group of people return in order to gauge their reactions to what has taken place so far.

Rubber (1936 film)

Rubber is a 1936 Dutch film directed by Johan De Meester and Gerard Rutten. It tells the story of Dutch newlyweds trying to adjust to a difficult life on a Sumatran plantation. The majority of the film is believed to be lost; a 63-minute fragment remains in the archives of the Dutch Film Museum.

Calculus

Calculus is the mathematical study of change, in the same way that geometry is the study of shape and algebra is the study of operations and their application to solving equations. It has two major branches, differential calculus (concerning rates of change and slopes of curves), and integral calculus (concerning accumulation of quantities and the areas under and between curves); these two branches are related to each other by the fundamental theorem of calculus. Both branches make use of the fundamental notions of convergence of infinite sequences and infinite series to a well-defined limit. Generally, modern calculus is considered to have been developed in the 17th century by Isaac Newton and Gottfried Leibniz. Today, calculus has widespread uses in science, engineering and economics and can solve many problems that algebra alone cannot.

Calculus is a part of modern mathematics education. A course in calculus is a gateway to other, more advanced courses in mathematics devoted to the study of functions and limits, broadly called mathematical analysis. Calculus has historically been called "the calculus of infinitesimals", or "infinitesimal calculus". The word "calculus" comes from Latin (calculus) and refers to a small stone used for counting. More generally, calculus (plural calculi) refers to any method or system of calculation guided by the symbolic manipulation of expressions. Some examples of other well-known calculi are propositional calculus, calculus of variations, lambda calculus, and process calculus.

National Association of Local Councils

The National Association of Local Councils (NALC) is an association of approximately 9,000 independently elected community, parish and town councils in England. The Head Office of the organisation is at 109 Great Russell Street in Bloomsbury, central London.

The main duties of the NALC include lobbying national government on behalf of its members, and their electorates. The association also provides support, advice and training for member councils, as well as holding an annual conference. The NALC also offers advice and technical guidance to individuals or groups who plan to create new councils for unrepresented communities or areas.

All member councils are represented on one of 38 local county associations of the NALC. It is the county associations who coordinate most of the support offered by the NALC to its members. Every county association then elects one representative from their members, who then sits on the associations National Council. It is the National Council that is largely responsible for representing members to national government.

She has been quite active as an actress on movies and mostly on stage since her debut. She also has written some lyrics for her mother Seiko Matsuda's songs.

She made her Kōhaku Uta Gassen debut in December 2011 singing "Ue o Muite Arukō" alongside her mother, Seiko Matsuda.

In July 2012 she debuted as a voice actress on TV animation Good Luck Girl!, which led her to be cast as Anna in Japanese version of Frozen.

In April 2014, she formed a duo called TRUSTRICK with a guitarist Billy. They released debut album "Eternity" on June 25.

Sayaka Kanda appeared as a special guest in the Alan Symphony Concert from December 20, 2014 alongside Tibetan Chinese diva Alan Dawa Dolma, and together, they sang a music piece originally performed by Alan titled "風の手紙"/"Kaze no Tegami" (Letter in the Wind).
