An oil is any nonpolar chemical substance, a viscous liquid at ambient temperatures and is both hydrophobic and lipophilic. Oils have a high carbon and hydrogen content and are flammable and surface active; the general definition of oil includes classes of chemical compounds that may be otherwise unrelated in structure and uses. Oils may be animal, vegetable, or petrochemical in origin, may be volatile or non-volatile, they are used for food, medical purposes and the manufacture of many types of paints and other materials. Specially prepared oils are used in some religious rituals as purifying agents. First attested in English 1176, the word oil comes from Old French oile, from Latin oleum, which in turn comes from the Greek ἔλαιον, "olive oil, oil" and that from ἐλαία, "olive tree", "olive fruit"; the earliest attested forms of the word are the Mycenaean Greek, e-ra-wo and, e-rai-wo, written in the Linear B syllabic script. Organic oils are produced in remarkable diversity by plants and other organisms through natural metabolic processes.
Lipid is the scientific term for the fatty acids and similar chemicals found in the oils produced by living things, while oil refers to an overall mixture of chemicals. Organic oils may contain chemicals other than lipids, including proteins and alkaloids. Lipids can be classified by the way that they are made by an organism, their chemical structure and their limited solubility in water compared to oils, they have a high carbon and hydrogen content and are lacking in oxygen compared to other organic compounds and minerals. Crude oil, or petroleum, its refined components, collectively termed petrochemicals, are crucial resources in the modern economy. Crude oil originates from ancient fossilized organic materials, such as zooplankton and algae, which geochemical processes convert into oil; the name "mineral oil" is a misnomer, in that minerals are not the source of the oil—ancient plants and animals are. Mineral oil is organic. However, it is classified as "mineral oil" instead of as "organic oil" because its organic origin is remote, because it is obtained in the vicinity of rocks, underground traps, sands.
Mineral oil refers to several specific distillates of crude oil. Several edible vegetable and animal oils, fats, are used for various purposes in cooking and food preparation. In particular, many foods are fried in oil much hotter than boiling water. Oils are used for flavoring and for modifying the texture of foods. Cooking oils are derived either from animal fat, as butter and other types, or plant oils from the olive, maize and many other species. Oils are applied to hair to give it a lustrous look, to prevent tangles and roughness and to stabilize the hair to promote growth. See hair conditioner. Oil has been used throughout history as a religious medium, it is considered a spiritually purifying agent and is used for anointing purposes. As a particular example, holy anointing oil has been an important ritual liquid for Judaism and Christianity. Color pigments are suspended in oil, making it suitable as a supporting medium for paints; the oldest known extant oil paintings date from 650 AD. Oils are used for instance in electric transformers.
Heat transfer oils are used both as coolants, for heating and in other applications of heat transfer. Given that they are non-polar, oils do not adhere to other substances; this makes them useful as lubricants for various engineering purposes. Mineral oils are more used as machine lubricants than biological oils are. Whale oil is preferred for lubricating clocks, because it does not evaporate, leaving dust, although its use was banned in the USA in 1980, it is a long-running myth that spermaceti from whales has still been used in NASA projects such as the Hubble Telescope and the Voyager probe because of its low freezing temperature. Spermaceti is not an oil, but a mixture of wax esters, there is no evidence that NASA has used whale oil; some oils burn in liquid or aerosol form, generating light, heat which can be used directly or converted into other forms of energy such as electricity or mechanical work. To obtain many fuel oils, crude oil is pumped from the ground and is shipped via oil tanker or a pipeline to an oil refinery.
There, it is converted from crude oil to diesel fuel, fuel oils, jet fuel, kerosene and liquefied petroleum gas. A 42-US-gallon barrel of crude oil produces 10 US gallons of diesel, 4 US gallons of jet fuel, 19 US gallons of gasoline, 7 US gallons of other products, 3 US gallons split between heavy fuel oil and liquified petroleum gases, 2 US gallons of heating oil; the total production of a barrel of crude into various products results in an increase to 45 US gallons. Not all oils used as fuels are mineral oils, see biodiesel and vegetable oil fuel. In the 18th and 19th cent
Atchison, Topeka and Santa Fe Railway
The Atchison and Santa Fe Railway referred to as the Santa Fe or AT&SF, was one of the larger railroads in the United States. Chartered in February 1859, the railroad reached the Kansas-Colorado border in 1873 and Pueblo, Colorado, in 1876. To create a demand for its services, the railroad set up real estate offices and sold farm land from the land grants that it was awarded by Congress. Despite the name, its main line never served New Mexico, as the terrain was too difficult; the Santa Fe was a pioneer in intermodal freight transport, an enterprise that included a tugboat fleet and an airline. Its bus line extended passenger transportation to areas not accessible by rail, ferryboats on the San Francisco Bay allowed travelers to complete their westward journeys to the Pacific Ocean; the AT&SF was the subject of a popular song, Harry Warren and Johnny Mercer's "On the Atchison and the Santa Fe", written for the film, The Harvey Girls. The railroad ceased operations on December 31, 1996, when it merged with the Burlington Northern Railroad to form the Burlington Northern and Santa Fe Railway.
The Atchison, Topeka & Santa Fe Railway was chartered on February 11, 1859, to join Atchison and Topeka, with Santa Fe, New Mexico. In its early years, the railroad opened Kansas to settlement. Much of its revenue came from wheat grown there and from cattle driven north from Texas to Wichita and Dodge City by September 1872. Rather than turn its survey southward at Dodge City, AT&SF headed southwest over Raton Pass because of coal deposits near Trinidad and Raton, New Mexico; the Denver & Rio Grande Railroad was aiming at Raton Pass, but AT&SF crews arose early one morning in 1878 and were hard at work with picks and shovels when the D&RGW crews showed up for breakfast. At the same time the two railroads had a series of skirmishes over occupancy of the Royal Gorge west of Cañon City, Colorado. Federal intervention prompted an out-of-court settlement on February 2, 1880, in the form of the so-called "Treaty of Boston", wherein D&RG was allowed to complete its line and lease it for use by Santa Fe.
D&RG paid an estimated $1.4 million to Santa Fe for its work within the Gorge and agreed not to extend its line to Santa Fe, while Santa Fe agreed to forego its planned routes to Denver and Leadville. Building across Kansas and eastern Colorado was simple, with few natural obstacles, but the railroad found it economically impossible because of the sparse population, it set up real estate offices in the area and promoted settlement across Kansas on the land, granted to it by Congress in 1863. It offered discounted fares to anyone. AT&SF reached Albuquerque in 1880. In March 1881 AT&SF connected with the Southern Pacific at Deming, New Mexico, forming the second transcontinental rail route; the railroad built southwest from Benson, Arizona, to Nogales on the Mexican border where it connected with the Sonora Railway, which the AT&SF had built north from the Mexican port of Guaymas. AT&SF purchased the Southern California Railway on Jan. 17, 1906. The Atlantic & Pacific Railroad was chartered in 1866 to build west from Springfield, along the 35th parallel of latitude to a junction with SP at the Colorado River.
The infant A&P had no rail connections. The line, to become the St. Louis–San Francisco Railway would not reach Springfield for another four years, SP did not build east from Mojave to the Colorado River until 1883. A&P started construction in 1868, built southwest into what would become Oklahoma, promptly entered receivership. In 1879 A&P struck a deal with the Santa Frisco railroads to construct a rail line for each; the railroads would jointly own the A&P railroad west of Albuquerque. In 1883 A&P reached Needles, where it connected with an SP line. A&P built a line between Tulsa, Oklahoma and St. Louis, Missouri for the Frisco, but the Tulsa-Albuquerque portion remained unbuilt; the Santa Fe began to expand: a line from Barstow, California, to San Diego in 1885 and to Los Angeles in 1887. By January 1890, the entire system consisted of some 7,500 miles of track; the Panic of 1893 had the same effect on the AT&SF. In 1895 AT&SF sold the Frisco and the Colorado Midland and wrote off the losses, but it still retained control of the A&P.
The Santa Fe Railway still wanted to reach California on its own rails, the state of California eagerly courted the railroad to break SP's monopoly. In 1897 the railroad traded the Sonora Railway of Mexico to SP for their line between Needles and Barstow, giving AT&SF its own line from Chicago to the Pac
Texas is the second largest state in the United States by both area and population. Geographically located in the South Central region of the country, Texas shares borders with the U. S. states of Louisiana to the east, Arkansas to the northeast, Oklahoma to the north, New Mexico to the west, the Mexican states of Chihuahua, Nuevo León, Tamaulipas to the southwest, while the Gulf of Mexico is to the southeast. Houston is the most populous city in Texas and the fourth largest in the U. S. while San Antonio is the second-most populous in the state and seventh largest in the U. S. Dallas–Fort Worth and Greater Houston are the fourth and fifth largest metropolitan statistical areas in the country, respectively. Other major cities include Austin, the second-most populous state capital in the U. S. and El Paso. Texas is nicknamed "The Lone Star State" to signify its former status as an independent republic, as a reminder of the state's struggle for independence from Mexico; the "Lone Star" can be found on the Texan state seal.
The origin of Texas's name is from the word taysha. Due to its size and geologic features such as the Balcones Fault, Texas contains diverse landscapes common to both the U. S. Southern and Southwestern regions. Although Texas is popularly associated with the U. S. southwestern deserts, less than 10% of Texas's land area is desert. Most of the population centers are in areas of former prairies, grasslands and the coastline. Traveling from east to west, one can observe terrain that ranges from coastal swamps and piney woods, to rolling plains and rugged hills, the desert and mountains of the Big Bend; the term "six flags over Texas" refers to several nations. Spain was the first European country to claim the area of Texas. France held a short-lived colony. Mexico controlled the territory until 1836 when Texas won its independence, becoming an independent Republic. In 1845, Texas joined the union as the 28th state; the state's annexation set off a chain of events that led to the Mexican–American War in 1846.
A slave state before the American Civil War, Texas declared its secession from the U. S. in early 1861, joined the Confederate States of America on March 2nd of the same year. After the Civil War and the restoration of its representation in the federal government, Texas entered a long period of economic stagnation. Four major industries shaped the Texas economy prior to World War II: cattle and bison, cotton and oil. Before and after the U. S. Civil War the cattle industry, which Texas came to dominate, was a major economic driver for the state, thus creating the traditional image of the Texas cowboy. In the 19th century cotton and lumber grew to be major industries as the cattle industry became less lucrative, it was though, the discovery of major petroleum deposits that initiated an economic boom which became the driving force behind the economy for much of the 20th century. With strong investments in universities, Texas developed a diversified economy and high tech industry in the mid-20th century.
As of 2015, it is second on the list of the most Fortune 500 companies with 54. With a growing base of industry, the state leads in many industries, including agriculture, energy and electronics, biomedical sciences. Texas has led the U. S. in state export revenue since 2002, has the second-highest gross state product. If Texas were a sovereign state, it would be the 10th largest economy in the world; the name Texas, based on the Caddo word táyshaʼ "friend", was applied, in the spelling Tejas or Texas, by the Spanish to the Caddo themselves the Hasinai Confederacy, the final -s representing the Spanish plural. The Mission San Francisco de los Tejas was completed near the Hasinai village of Nabedaches in May 1690, in what is now Houston County, East Texas. During Spanish colonial rule, in the 18th century, the area was known as Nuevo Reino de Filipinas "New Kingdom of the Philippines", or as provincia de los Tejas "province of the Tejas" also provincia de Texas, "province of Texas", it was incorporated as provincia de Texas into the Mexican Empire in 1821, declared a republic in 1836.
The Royal Spanish Academy recognizes both spellings and Texas, as Spanish-language forms of the name of the U. S. State of Texas; the English pronunciation with /ks/ is unetymological, based in the value of the letter x in historical Spanish orthography. Alternative etymologies of the name advanced in the late 19th century connected the Spanish teja "rooftile", the plural tejas being used to designate indigenous Pueblo settlements. A 1760s map by Jacques-Nicolas Bellin shows a village named Teijas on Trinity River, close to the site of modern Crockett. Texas is the second-largest U. S. state, with an area of 268,820 square miles. Though 10% larger than France and twice as large as Germany or Japan, it ranks only 27th worldwide amongst country subdivisions by size. If it were an independent country, Texas would be the 40th largest behind Zambia. Texas is in the south central part of the United States of America. Three of its borders are defined by rivers; the Rio Grande forms a natural border with the Mexican states of Chihuahua, Nuevo León, Tamaulipas to the south.
The Red River forms a natural border with Arkansas to the north. The Sabine River forms a natural border with Louisiana to the east; the Texas Panhandle has an eastern border with Oklahoma at 100° W, a northern border with Oklahoma at 36°30' N and a western
Terry County, Texas
Terry County is a county located in the U. S. state of Texas. As of the 2010 census, its population was 12,651, its county seat is Brownfield. The county was created in 1876 and organized in 1904, it is named for a colonel in the Confederate Army. Terry County is now a moist county. In 1877, the ill-fated Nolan Expedition crossed the county in search of livestock stolen by Comanche renegades; the various Indian tribes had moved on by the time of white settlement, due to the depletion of the buffalo herds by hunters. Terry County was formed from Bexar County in 1876 and named for Col. Benjamin Franklin Terry, who commanded the Terry's Texas Rangers in the Civil War. Terry County was organized in 1904. Brownfield as became the county seat; the county was settled by ranchers such as Ira J. Coulver, J. R. Quinn, Englishman Q. Bone and Marion V. Brownfield. By 1910 Terry County had 235 farms and 23,000 acres of improved land, with corn being the most important crop. Oil was discovered in the county in 1940 Terry County lies in the oil-rich north Permian Basin, the discovery of oil led to production.
By 1991 363,143,000 barrels of crude had been extracted from Terry County lands since 1940. In 1991 Terry County was among the leading cotton counties in Texas. According to the U. S. Census Bureau, the county has a total area of 891 square miles, of which 889 square miles is land and 2.1 square miles is water. U. S. Highway 62 U. S. Highway 82 U. S. Highway 380 U. S.

Culpeper County, Virginia
Culpeper County is a county located in the central region of the Commonwealth of Virginia. As of the 2010 census, the population was 46,689, its county seat and only incorporated community is Culpeper. Home to some of Virginia's most famous plantation homes and thousands of acres of farmland, the rolling hills of the Piedmont region and the westernmost flats of the Northern Neck collide in rural Culpeper County. Culpeper County is included in the Washington-Arlington-Alexandria, DC-VA-MD-WV Metropolitan Statistical Area. At the time of European encounter, the inhabitants of the area that became Culpeper County were a Siouan-speaking sub-group of the Manahoac tribe called the Tegninateo. Culpeper County was established in 1749 from Orange County; the county is named for Thomas Colepeper, 2nd Baron Colepeper, colonial governor of Virginia from 1677 to 1683. During the Civil War the Battle of Cedar Mountain took place on August 9, 1862 and the Battle of Brandy Station on June 9, 1863, in Culpeper County.
In May 1749, the first Culpeper Court convened in the home of Robert Tureman, not far from where the Town of Culpeper is now located. In July 1749, Tureman commissioned 17-year-old George Washington as the first County surveyor. One of his first duties was to lay out the County's courthouse complex, which included the courthouse, stocks and accessory buildings. By 1752 the complex stood at what is now the northeast corner of Main Streets; the courthouse village was named the Town of Fairfax after Thomas Fairfax, 6th Lord Fairfax of Cameron. During the Virginia convention held in May 1775, the colony was divided into sixteen districts; each district had instructions to raise a battalion of men "to march at a minute's notice." Culpeper and Fauquier, forming one district, raised 350 men in "Clayton's old field" on the Catalpa estate, who came to be called the Culpeper Minute Men. In December, the Minute Men, marching under their flag depicting a rattlesnake and inscribed with the words "Liberty or Death" and "Don't Tread on Me", took part in the Battle of Great Bridge, the first Revolutionary battle on Virginia soil.
The Culpeper Minute Men reorganized in 1860 in response to the impending Civil War and became part of 13th Infantry's Company B. The Culpeper Minutemen were again organized for World War I, joined the 116th Infantry. In 1833, based on the county's growing population and those in the northwestern area needing to have better access to a county seat, Rappahannock County, Virginia was founded by an act of the Virginia General Assembly; the 267 square miles of that county's land was carved from Culpeper County. Culpeper was the site of the Battle of Brandy Station and the boyhood home to Civil War General A. P. Hill; the negative impact of the Massive Resistance campaign against school integration led to the statewide election of a pro-desegregation governor. By the middle of the 1970s, Culpeper was the last county in Virginia to desegregrate its public schools. In 2018 Culpeper County Public Schools has two middle schools and two high schools. In 1935 the Rotary Club of Culpeper began a college loan fund, which in 1966 became a four-year scholarship based on academic achievement.
The group provides a Technical School scholarship based on academic achievement. Culpeper County is home to site for many world-class equestrian events, it was here. The town of Culpeper was rated #10 by Norman Crampton, author of "The 100 Best Small Towns in America," in February, 1993. In April 2016, the county Board of Supervisors denied a routine request from the Islamic Center of Culpeper for a pump and haul permit to serve their envisioned mosque; this act resulted in a lawsuit by the U. S. Department of Justice in December. Culpeper County is in the foothills of the Blue Ridge Mountains, which are accessed beginning with Old Rag Mountain and the Skyline Drive just up Route 522. According to the U. S. Census Bureau, the county has a total area of 383 square miles, of which 379 square miles is land and 3.3 square miles is water.

Recent media investigations regarding law enforcement procurement of military equipment through the "1033" program offered by the Defense Logistics Agency identified Culpeper County as having received, as donations, a "Mine Resistant Vehicle" in 2013 worth $412,000 and twenty night vision optics worth an additional $136,000.00. This equipment, valued at more than half a million dollars, was obtained at no additional cost to Culpeper County residents.

United States Census Bureau
The United States Census Bureau is a principal agency of the U. S. Federal Statistical System, responsible for producing data about the American people and economy; the Census Bureau is part of the U. S. Department of Commerce and its director is appointed by the President of the United States; the Census Bureau's primary mission is conducting the U. S. Census every ten years, which allocates the seats of the U. S. House of Representatives to the states based on their population; the Bureau's various censuses and surveys help allocate over $400 billion in federal funds every year and it helps states, local communities, businesses make informed decisions. The information provided by the census informs decisions on where to build and maintain schools, transportation infrastructure, police and fire departments. In addition to the decennial census, the Census Bureau continually conducts dozens of other censuses and surveys, including the American Community Survey, the U. S. Economic Census, the Current Population Survey.
Furthermore and foreign trade indicators released by the federal government contain data produced by the Census Bureau. Article One of the United States Constitution directs the population be enumerated at least once every ten years and the resulting counts used to set the number of members from each state in the House of Representatives and, by extension, in the Electoral College; the Census Bureau now conducts a full population count every 10 years in years ending with a zero and uses the term "decennial" to describe the operation. Between censuses, the Census Bureau makes population projections. In addition, Census data directly affects how more than $400 billion per year in federal and state funding is allocated to communities for neighborhood improvements, public health, education and more; the Census Bureau is mandated with fulfilling these obligations: the collecting of statistics about the nation, its people, economy. The Census Bureau's legal authority is codified in Title 13 of the United States Code.
The Census Bureau conducts surveys on behalf of various federal government and local government agencies on topics such as employment, health, consumer expenditures, housing. Within the bureau, these are known as "demographic surveys" and are conducted perpetually between and during decennial population counts; the Census Bureau conducts economic surveys of manufacturing, retail and other establishments and of domestic governments. Between 1790 and 1840, the census was taken by marshals of the judicial districts; the Census Act of 1840 established a central office. Several acts followed that revised and authorized new censuses at the 10-year intervals. In 1902, the temporary Census Office was moved under the Department of Interior, in 1903 it was renamed the Census Bureau under the new Department of Commerce and Labor; the department was intended to consolidate overlapping statistical agencies, but Census Bureau officials were hindered by their subordinate role in the department. An act in 1920 changed the date and authorized manufacturing censuses every two years and agriculture censuses every 10 years.
In 1929, a bill was passed mandating the House of Representatives be reapportioned based on the results of the 1930 Census. In 1954, various acts were codified into Title 13 of the US Code. By law, the Census Bureau must count everyone and submit state population totals to the U. S. President by December 31 of any year ending in a zero. States within the Union receive the results in the spring of the following year; the United States Census Bureau defines four statistical regions, with nine divisions. The Census Bureau regions are "widely used...for data collection and analysis". The Census Bureau definition is pervasive. Regional divisions used by the United States Census Bureau: Region 1: Northeast Division 1: New England Division 2: Mid-Atlantic Region 2: Midwest Division 3: East North Central Division 4: West North Central Region 3: South Division 5: South Atlantic Division 6: East South Central Division 7: West South Central Region 4: West Division 8: Mountain Division 9: Pacific Many federal, state and tribal governments use census data to: Decide the location of new housing and public facilities, Examine the demographic characteristics of communities and the US, Plan transportation systems and roadways, Determine quotas and creation of police and fire precincts, Create localized areas for elections, utilities, etc.
Gathers population information every 10 years The United States Census Bureau is committed to confidentiality, guarantees non-disclosure of any addresses or personal information related to individuals or establishments. Title 13 of the U. S. Code establishes penalties for the disclosure of this information. All Census employees must sign an affidavit of non-disclosure prior to employment; the Bureau cannot share responses, addresses or personal information with anyone including United States or foreign government
1940 United States Census
The Sixteenth United States Census, conducted by the Census Bureau, determined the resident population of the United States to be 132,164,569, an increase of 7.3 percent over the 1930 population of 123,202,624 people. The census date of record was April 1, 1940. A number of new questions were asked including where people were 5 years before, highest educational grade achieved, information about wages; this census introduced sampling techniques. Other innovations included a field test of the census in 1939; this was the first census in which every state had a population greater than 100,000. The 1940 census collected the following information: In addition, a sample of individuals were asked additional questions covering age at first marriage and other topics. Full documentation on the 1940 census, including census forms and a procedural history, is available from the Integrated Public Use Microdata Series. Following completion of the census, the original enumeration sheets were microfilmed; as required by Title 13 of the U.
S. Code, access to identifiable information from census records was restricted for 72 years. Non-personally identifiable information Microdata from the 1940 census is available through the Integrated Public Use Microdata Series. Aggregate data for small areas, together with electronic boundary files, can be downloaded from the National Historical Geographic Information System. On April 2, 2012—72 years after the census was taken—microfilmed images of the 1940 census enumeration sheets were released to the public by the National Archives and Records Administration; the records are indexed only by enumeration district upon initial release.
