Hallam, Nebraska
Hallam is a village in Lancaster County, Nebraska, United States. It is part of the Lincoln, Nebraska Metropolitan Statistical Area. The population was 213 at the 2010 census. History Hallam was platted in 1892 when the Chicago, Rock Island and Pacific Railroad was extended to that point. The land was sold by Frederick Schneider, who was asked to name the village. However, Schneider's proposals were already names of towns in Nebraska, so the first landowner in the village, Jacob Schadd, was given the honor of naming the settlement. Schadd suggested Hallau, after his hometown in Switzerland. However, due to a transcription error at the post office, the name was recorded as Hallam rather than Hallau, similar to the error which altered Norfork, Nebraska, to Norfolk, Nebraska. Mrs. Maggie Classen owned several lots in Hallam, unusual for a woman in the 1890s, upon which were built the telephone office and a doctor's office. By the early 1900s, Hallam featured a bank, a hardware stor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Village (United States)
In the United States, the meaning of village varies by geographic area and legal jurisdiction. In many areas, "village" is a term, sometimes informal, for a type of administrative division at the local government level. Since the Tenth Amendment to the United States Constitution prohibits the federal government from legislating on local government, the states are free to have political subdivisions called "villages" or not to and to define the word in many ways. Typically, a village is a type of municipality, although it can also be a special district or an unincorporated area. It may or may not be recognized for governmental purposes. In informal usage, a U.S. village may be simply a relatively small clustered human settlement without formal legal existence. In colonial New England, a village typically formed around the meetinghouses that were located in the center of each town.Joseph S. Wood (2002), The New England Village', Johns Hopkins University Press Many of these colon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chicago, Rock Island And Pacific Railroad
The Chicago, Rock Island and Pacific Railroad (CRI&P RW, sometimes called ''Chicago, Rock Island and Pacific Railway'') was an American Class I railroad. It was also known as the Rock Island Line, or, in its final years, The Rock. At the end of 1970, it operated 7,183 miles of road on 10,669 miles of track; that year it reported 20,557 million ton-miles of revenue freight and 118 million passenger miles. (Those totals may or may not include the former Burlington-Rock Island Railroad.) The song "Rock Island Line", a spiritual from the late 1920s first recorded in 1934, was inspired by the railway. History Incorporation Its predecessor, the Rock Island and La Salle Railroad Company, was incorporated in Illinois on February 27, 1847, and an amended charter was approved on February 7, 1851, as the Chicago and Rock Island Railroad. Construction began in Chicago on October 1, 1851, and the first train was operated on October 10, 1852, between Chicago and Joliet. Construction co ...

Population Density
Population density (in agriculture: standing stock or plant density) is a measurement of population per unit land area. It is mostly applied to humans, but sometimes to other living organisms too. It is a key geographical term.Matt RosenberPopulation Density Geography.about.com. March 2, 2011. Retrieved on December 10, 2011. In simple terms, population density refers to the number of people living in an area per square kilometre, or other unit of land area. Biological population densities Population density is population divided by total land area, sometimes including seas and oceans, as appropriate. Low densities may cause an extinction vortex and further reduce fertility. This is called the Allee effect after the scientist who identified it. Examples of the causes of reduced fertility in low population densities are * Increased problems with locating sexual mates * Increased inbreeding Human densities Population density is the number of people per unit of area, usuall ...

Census
A census is the procedure of systematically acquiring, recording and calculating information about the members of a given population. This term is used mostly in connection with national population and housing censuses; other common censuses include censuses of agriculture, traditional culture, business, supplies, and traffic censuses. The United Nations (UN) defines the essential features of population and housing censuses as "individual enumeration, universality within a defined territory, simultaneity and defined periodicity", and recommends that population censuses be taken at least every ten years. UN recommendations also cover census topics to be collected, official definitions, classifications and other useful information to co-ordinate international practices. The UN's Food and Agriculture Organization (FAO), in turn, defines the census of agriculture as "a statistical operation for collecting, processing and disseminating data on the structure of agriculture, covering th ...

2013 El Reno Tornado
During the early evening of Friday, May 31, 2013, a very large and powerful tornado occurred over rural areas of Central Oklahoma. This rain-wrapped, multiple-vortex tornado was the widest tornado ever recorded and was part of a larger weather system that produced dozens of tornadoes over the preceding days. The tornado initially touched down at 6:03 p.m. Central Daylight Time (2303 UTC) about west-southwest of El Reno, rapidly growing in size and becoming more violent as it tracked through central portions of Canadian County. Remaining over mostly open terrain, the tornado did not impact many structures; however, measurements from mobile weather radars revealed extreme winds up to within the vortex. These are among the highest observed wind speeds on Earth, just slightly lower than the wind speeds of the 1999 Bridge Creek–Moore tornado. As it crossed U.S. 81, it had grown to a record-breaking width of , beating the previous width record held by the 2004 Ha ...

Fujita Scale
The Fujita scale (F-Scale; ), or Fujita–Pearson scale (FPP scale), is a scale for rating tornado intensity, based primarily on the damage tornadoes inflict on human-built structures and vegetation. The official Fujita scale category is determined by meteorologists and engineers after a ground or aerial damage survey, or both; and depending on the circumstances, ground-swirl patterns (cycloidal marks), weather radar data, witness testimonies, media reports and damage imagery, as well as photogrammetry or videogrammetry if motion picture recording is available. The Fujita scale was replaced with the Enhanced Fujita scale (EF-Scale) in the United States in February 2007. In April 2013, Canada adopted the EF-Scale over the Fujita scale along with 31 "Specific Damage Indicators" used by Environment Canada (EC) in their ratings. Background The scale was introduced in 1971 by Ted Fujita of the University of Chicago, in collaboration with Allen Pearson, head of the National Sev ...

Coal-power Plant
A coal-fired power station or coal power plant is a thermal power station which burns coal to generate electricity. Worldwide, there are about 8,500 coal-fired power stations totaling over 2,000 gigawatts capacity. They generate about a third of the world's electricity, but cause many illnesses and early deaths, mainly from air pollution. A coal-fired power station is a type of fossil fuel power station. The coal is usually pulverized and then burned in a pulverized coal-fired boiler. The furnace heat converts boiler water to steam, which is then used to spin turbines that turn generators. Thus chemical energy stored in coal is converted successively into thermal energy, mechanical energy and, finally, electrical energy. Coal-fired power stations emit over 10 Gt of carbon dioxide each year, about one fifth of world greenhouse gas emissions, so are the single largest cause of climate change. More than half of all the coal-fired electricity in the world is generated in C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Power
Nuclear power is the use of nuclear reactions to produce electricity. Nuclear power can be obtained from nuclear fission, nuclear decay and nuclear fusion reactions. Presently, the vast majority of electricity from nuclear power is produced by nuclear ''fission'' of uranium and plutonium in nuclear power plants. Nuclear ''decay'' processes are used in niche applications such as radioisotope thermoelectric generators in some space probes such as ''Voyager 2''. Generating electricity from fusion power, ''fusion'' power remains the focus of international research. Most nuclear power plants use thermal reactors with enriched uranium in a Nuclear fuel cycle#Once-through nuclear fuel cycle, once-through fuel cycle. Fuel is removed when the percentage of neutron poison, neutron absorbing atoms becomes so large that a nuclear chain reaction, chain reaction can no longer be sustained, typically three years. It is then cooled for several years in on-site spent fuel pools before being tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Power In The United States
Nuclear power in the United States is provided by 92 commercial reactors with a net capacity of 94.7 gigawatts (GW), with 61 pressurized water reactors and 31 boiling water reactors. In 2019, they produced a total of 809.41 terawatt-hours of electricity, which accounted for 20% of the nation's total electric energy generation. In 2018, nuclear comprised nearly 50 percent of US emission-free energy generation. , there are two new reactors under construction with a gross electrical capacity of 2,500 MW, while 39 reactors have been permanently shut down. The United States is the world's largest producer of commercial nuclear power, and in 2013 generated 33% of the world's nuclear electricity. With the past and future scheduled plant closings, China and Russia could surpass the United States in nuclear energy production. As of October 2014, the Nuclear Regulatory Commission (NRC) has granted license renewals providing 20-year extensions to a total of 74 reactors. In early 2014, th ...

Livery Yard
A livery yard, livery stable or boarding stable, is a stable where horse owners pay a weekly or monthly fee to keep their horses. A livery or boarding yard is not usually a riding school and the horses are not normally for hire (unless on working livery - see below). Facilities at a livery yard normally include a loose box or stable and access for the horse to graze on grass. History of livery stables in North America Historically in North America, "livery stable" had a somewhat different meaning: a stable where horses, teams and wagons were for hire, but also where privately owned horses could be boarded for a short time. Because of the temporary boarding aspect, livery stables were often attached to a hotel or boarding house. Located at Buffalo, New York, the C. W. Miller Livery Stable is an example of a multi-story livery stable. The livery stable was a necessary institution of every American town, but its role has been generally overlooked by historians.

Druggist
A pharmacist, also known as a chemist (Commonwealth English) or a druggist (North American and, archaically, Commonwealth English), is a healthcare professional who prepares, controls and distributes medicines and provides advice and instructions on the correct and safe use of medicines to achieve maximum benefit, minimal side effects and to avoid drug interactions. They also serve as primary care providers in the community. Pharmacists undergo university or graduate-level education to understand the biochemical mechanisms and actions of drugs, drug uses, therapeutic roles, side effects, potential drug interactions, and monitoring parameters. This is mated to anatomy, physiology, and pathophysiology. Pharmacists interpret and communicate this specialized knowledge to patients, physicians, and other health care providers. Among other licensing requirements, different countries require pharmacists to hold either a Bachelor of Pharmacy, Master of Pharmacy, or Doctor of Pharmacy d ...
