Curling is a sport in which players slide stones on a sheet of ice toward a target area which is segmented into four concentric circles. It is related to bowls, boules and shuffleboard. Two teams, each with four players, take turns sliding heavy, polished granite rocks, also called stones, across the ice curling sheet toward the house, a circular target marked on the ice. Each team has eight stones, with each player throwing two. The purpose is to accumulate the highest score for a game; points are scored for the stones resting closest to the centre of the house at the conclusion of each end, which is completed when both teams have thrown all of their stones. A game usually consists of eight or ten ends.
The player can induce a curved path, described as curl, by causing the stone to slowly turn as it slides. The path of the rock may be further influenced by two sweepers with brooms or brushes, who accompany it as it slides down the sheet and sweep the ice in front of the stone. "Sweeping a rock" decreases the friction, which makes the stone travel a straighter path (with less "curl") and a longer distance. A great deal of strategy and teamwork go into choosing the ideal path and placement of a stone for each situation, and the skills of the curlers determine the degree to which the stone will achieve the desired result.

George Herbert Walker Bush (June 12, 1924 – November 30, 2018) was an American politician, diplomat, and businessman who served as the 41st president of the United States from 1989 to 1993. A member of the Republican Party, Bush also served as the 43rd vice president from 1981 to 1989 under Ronald Reagan, in the U.S. House of Representatives, as U.S. Ambassador to the United Nations, and as Director of Central Intelligence.
Bush was raised in Greenwich, Connecticut, and attended Phillips Academy before serving in the United States Navy Reserve during World War II. After the war, he graduated from Yale and moved to West Texas, where he established a successful oil company. After an unsuccessful run for the United States Senate, he won the election to the 7th congressional district of Texas in 1966. President Richard Nixon appointed Bush to the position of Ambassador to the United Nations in 1971 and to the position of chairman of the Republican National Committee in 1973. In 1974, President Gerald Ford appointed him as the Chief of the Liaison Office to the People's Republic of China, and in 1976 Bush became the Director of Central Intelligence. Bush ran for president in 1980, but was defeated in the Republican presidential primaries by Ronald Reagan. He was then elected vice president in 1980 and 1984 as Reagan's running mate.
In the 1988 presidential election, Bush defeated Democrat Michael Dukakis, becoming the first incumbent vice president to be elected president since Martin Van Buren in 1836. Foreign policy drove the Bush presidency, as he navigated the final years of the Cold War and played a key role in the reunification of Germany.

Ötzi, also called the Iceman, is the natural mummy of a man who lived between 3400 and 3100 BCE, discovered in September 1991 in the Ötztal Alps (hence the nickname "Ötzi") on the border between Austria and Italy.
Ötzi is believed to have been murdered, due to the discovery of an arrowhead embedded in his left shoulder and various other wounds. The nature of his life and the circumstances of his death are the subject of much investigation and speculation.
He is Europe's oldest known natural human mummy, offering an unprecedented view of Chalcolithic (Copper Age) Europeans. His body and belongings are displayed in the South Tyrol Museum of Archaeology in Bolzano, South Tyrol, Italy.


== Discovery ==

Ötzi was found on 19 September 1991 by two German tourists, at an elevation of 3,210 metres (10,530 ft) on the east ridge of the Fineilspitze in the Ötztal Alps on the Austrian–Italian border, near Similaun mountain and the Tisenjoch pass. When the tourists, Helmut and Erika Simon, first saw the body, they both believed that they had happened upon a recently deceased mountaineer. The next day, a mountain gendarme and the keeper of the nearby Similaunhütte first attempted to remove the body, which was frozen in ice below the torso, using a pneumatic drill and ice-axes, but had to give up due to bad weather. Within a short time, eight groups visited the site, among whom were mountaineers Hans Kammerlander and Reinhold Messner. The body was semi-officially extracted on 22 September and officially salvaged the following day.

A sneeze (also known as sternutation) is a semi-autonomous, convulsive expulsion of air from the lungs through the nose and mouth, usually caused by foreign particles irritating the nasal mucosa. A sneeze expels air forcibly from the mouth and nose in an explosive, spasmodic involuntary action. This action allows for mucus to escape through the nasal cavity. Sneezing is possibly linked to sudden exposure to bright light, sudden change (fall) in temperature, breeze of cold air, a particularly full stomach, exposure to allergens, or viral infection. Because sneezes can spread disease through infectious aerosol droplets, it is recommended to cover one's mouth and nose with the forearm, the inside of the elbow, a tissue or a handkerchief while sneezing. In addition to covering the mouth, looking down is also recommended in order to change the direction of the droplets spread and avoid high concentration in the human breathing heights.
The function of sneezing is to expel mucus containing foreign particles or irritants and cleanse the nasal cavity. During a sneeze, the soft palate and palatine uvula depress while the back of the tongue elevates to partially close the passage to the mouth so that air ejected from the lungs may be expelled through the nose. Because the closing of the mouth is partial, a considerable amount of this air is usually also expelled from the mouth. The force and extent of the expulsion of the air through the nose varies.

A camel is an even-toed ungulate in the genus Camelus that bears distinctive fatty deposits known as "humps" on its back. Camels have long been domesticated and, as livestock, they provide food (milk and meat) and textiles (fiber and felt from hair). Camels are working animals especially suited to their desert habitat and are a vital means of transport for passengers and cargo. There are three surviving species of camel. The one-humped dromedary makes up 94% of the world's camel population, and the two-humped Bactrian camel makes up 6%. The Wild Bactrian camel is a separate species and is now critically endangered.
The word camel is also used informally in a wider sense, where the more correct term is "camelid", to include all seven species of the family Camelidae: the true camels (the above three species), along with the "New World" camelids: the llama, the alpaca, the guanaco, and the vicuña. The word itself is derived via Latin: camelus and Greek: κάμηλος (kamēlos) from Hebrew, Arabic or Phoenician: gāmāl.

The average life expectancy of a camel is 40 to 50 years. A full-grown adult dromedary camel stands 1.85 m (6 ft 1 in) at the shoulder and 2.15 m (7 ft 1 in) at the hump.

A language is a structured system of communication used by humans, including speech and gesture (spoken language), sign, and often writing. The most widely-spoken languages have writing systems of glyphs that enable sounds or gestures to be inscribed for later reactivation.
The scientific study of language is called linguistics. Critical examinations of languages, such as philosophy of language, the relationships between language and thought, etc, such as how words represent experience, have been debated at least since Gorgias and Plato in ancient Greek civilization. Thinkers such as Rousseau (1712 – 1778) have debated that language originated from emotions, while others like Kant (1724 –1804), have held that languages originated from rational and logical thought. Twentieth century philosophers such as Wittgenstein (1889 – 1951) argued that philosophy is really the study of language itself. Major figures in contemporary linguistics of these times include Ferdinand de Saussure and Noam Chomsky.
Estimates of the number of human languages in the world vary between 5,000 and 7,000. However, any precise estimate depends on the arbitrary distinction (dichotomy) between languages and dialect. Natural languages are spoken or signed (or both), but any language can be encoded into secondary media using auditory, visual, or tactile stimuli – for example, in writing, whistling, signing, or braille.

Sharks are a group of elasmobranch fish characterized by a cartilaginous skeleton, five to seven gill slits on the sides of the head, and pectoral fins that are not fused to the head. Modern sharks are classified within the clade Selachimorpha (or Selachii) and are the sister group to the rays. However, the term "shark" has also been used for extinct members of the subclass Elasmobranchii outside the Selachimorpha, such as Cladoselache and Xenacanthus, as well as other Chondrichthyes such as the holocephalid eugenedontidans.
Under this broader definition, the earliest known sharks date back to more than 420 million years ago. Acanthodians are often referred to as "spiny sharks"; though they are not part of Chondrichthyes proper, they are a paraphyletic assemblage leading to cartilaginous fish as a whole.  Since then, sharks have diversified into over 500 species. They range in size from the small dwarf lanternshark (Etmopterus perryi), a deep sea species of only 17 centimetres (6.7 in) in length, to the whale shark (Rhincodon typus), the largest fish in the world, which reaches approximately 12 metres (40 ft) in length. Sharks are found in all seas and are common to depths of 2,000 metres (6,600 ft). They generally do not live in freshwater although there are a few known exceptions, such as the bull shark and the river shark, which can be found in both seawater and freshwater. Sharks have a covering of dermal denticles that protects their skin from damage and parasites in addition to improving their fluid dynamics.

The sea otter (Enhydra lutris) is a marine mammal native to the coasts of the northern and eastern North Pacific Ocean. Adult sea otters typically weigh between 14 and 45 kg (31 and 99 lb), making them the heaviest members of the weasel family, but among the smallest marine mammals. Unlike most marine mammals, the sea otter's primary form of insulation is an exceptionally thick coat of fur, the densest in the animal kingdom. Although it can walk on land, the sea otter is capable of living exclusively in the ocean.

The sea otter inhabits nearshore environments, where it dives to the sea floor to forage. It preys mostly on marine invertebrates such as sea urchins, various mollusks and crustaceans, and some species of fish. Its foraging and eating habits are noteworthy in several respects. First, its use of rocks to dislodge prey and to open shells makes it one of the few mammal species to use tools. In most of its range, it is a keystone species, controlling sea urchin populations which would otherwise inflict extensive damage to kelp forest ecosystems. Its diet includes prey species that are also valued by humans as food, leading to conflicts between sea otters and fisheries.

The Volvo Group (Swedish: Volvokoncernen; legally Aktiebolaget Volvo, shortened to AB Volvo, stylized as VOLVO) is a Swedish multinational manufacturing company headquartered in Gothenburg. While its core activity is the production, distribution and sale of trucks, buses and construction equipment, Volvo also supplies marine and industrial drive systems and financial services. In 2016, it was the world's second largest manufacturer of heavy-duty trucks.Automobile manufacturer Volvo Cars, also based in Gothenburg, was part of AB Volvo until 1999, when it was sold to the Ford Motor Company. Since 2010 it has been owned by the Chinese multinational automotive company Geely Holding Group. Both AB Volvo and Volvo Cars share the Volvo logo and cooperate in running the Volvo Museum in Sweden.
The company was first listed on the Stockholm Stock Exchange in 1935, and was on the NASDAQ indices from 1985 to 2007.Volvo was established in 1915 as a subsidiary of SKF, a ball bearing manufacturer; however both the Volvo Group and Volvo Cars regard the rollout of the company's first car series, the Volvo ÖV 4, on 14 April 1927, as their beginning. The building remains (57°42′50″N 11°55′19″E).

=== Early years and international expansion ===

The brand name Volvo was originally registered as a trademark in May 1911 with the intention to be used for a new series of SKF ball bearings. It means "I roll" in Latin, conjugated from "volvere". The idea was short-lived, and SKF decided to simply use its initials as the trademark for all its bearing products.In 1924, Assar Gabrielsson, an SKF sales manager, and a KTH Royal Institute of Technology educated engineer Gustav Larson, decided to start construction of a Swedish car.

A barcode or bar code is a method of representing data in a visual, machine-readable form. Initially, barcodes represented data by varying the widths and spacings of parallel lines. These barcodes, now commonly referred to as linear or one-dimensional (1D), can be scanned by special optical scanners, called barcode readers, of which there are several types. Later, two-dimensional (2D) variants were developed, using rectangles, dots, hexagons and other patterns, called matrix codes or 2D barcodes, although they do not use bars as such. 2D barcodes can be read using purpose-built 2D optical scanners, which exist in a few different forms. 2D barcodes can also be read by a digital camera connected to a microcomputer running software that takes a photographic image of the barcode and analyzes the image to deconstruct and decode the 2D barcode. A mobile device with an inbuilt camera, such as smartphone, can function as the latter type of 2D barcode reader using specialized application software. (The same sort of mobile device could also read 1D barcodes, depending on the application software.)
The barcode was invented by Norman Joseph Woodland and Bernard Silver and patented in the US in 1951. The invention was based on Morse code that was extended to thin and thick bars. However, it took over twenty years before this invention became commercially successful.

A library is a collection of materials, books or media that are easily accessible for use and not just for display purposes. It is responsible for housing updated information in order to meet the user's needs on a daily basis. A Library provides physical (hard copies documents) or digital access (soft copies) materials, and may be a physical location or a virtual space, or both. A library's collection can include printed materials and other physical resources in many formats such as DVDs, CDs and Cassette as well as access to information, music or other content held on bibliographic databases.
A library, which may vary widely in size, may be organized for use and maintained by a public body such as a government, an institution/ schools, a corporation, or a private individual. In addition to providing materials, libraries also provide the services of librarians who are trained and experts at finding, selecting, circulating and organizing information and at interpreting information needs, navigating and analyzing very large amounts of information with a variety of resources. Hence, librarians go an extra mile to meet the user's need by ensuring that their users are satisfied with the information provided. A Librarian is one person who is expected to be very vibrant and innovative especially in this digital world.Library buildings often provide quiet and conducive areas for studying, as well as common areas for group study and collaboration, and may provide public facilities for access to their electronic resources for instance Computers and Desktop and access to the Internet. The library's clientele and therefore the services offered vary depending on its type: users of a public library have different needs from those of a special library, for example. Libraries may also be community hubs, where programs are delivered and people engage in lifelong learning.

Benjamin Franklin  (January 17, 1706 [O.S. January 6, 1705] –  April 17, 1790) was one of the Founding Fathers of the United States. A polymath, he was a leading writer, printer, political philosopher, politician, Freemason, postmaster, scientist, inventor, humorist, civic activist, statesman, and diplomat. As a scientist, he was a major figure in the American Enlightenment and the history of physics for his discoveries and theories regarding electricity. As an inventor, he is known for the lightning rod, bifocals, and the Franklin stove, among other inventions. He founded many civic organizations, including the Library Company, Philadelphia's first fire department, and the University of Pennsylvania.Franklin earned the title of "The First American" for his early and indefatigable campaigning for colonial unity, initially as an author and spokesman in London for several colonies. As the first United States ambassador to France, he exemplified the emerging American nation. Franklin was foundational in defining the American ethos as a marriage of the practical values of thrift, hard work, education, community spirit, self-governing institutions, and opposition to authoritarianism both political and religious, with the scientific and tolerant values of the Enlightenment. In the words of historian Henry Steele Commager, "In Franklin could be merged the virtues of Puritanism without its defects, the illumination of the Enlightenment without its heat." To Walter Isaacson, this makes Franklin "the most accomplished American of his age and the most influential in inventing the type of society America would become."Franklin became a successful newspaper editor and printer in Philadelphia, the leading city in the colonies, publishing the Pennsylvania Gazette at the age of 23. He became wealthy publishing this and Poor Richard's Almanack, which he authored under the pseudonym "Richard Saunders". After 1767, he was associated with the Pennsylvania Chronicle, a newspaper that was known for its revolutionary sentiments and criticisms of the policies of the British Parliament and the Crown.He pioneered and was the first president of Academy and College of Philadelphia which opened in 1751 and later became the University of Pennsylvania.
