Three Kids Mine
The Three Kids Mine is a defunct open-pit manganese mine in Henderson, Nevada, United States which operated from 1917 to 1961. The abandoned mine—located near Nevada State Route 564 just south of the Lake Las Vegas neighborhood—now stands popularly used as a location for graffiti art and is planned for redevelopment to a residential area as of 2023. History Operations In 1917, three men—B.R. Jefferson, B. Edwards, and J. Marrs—discovered a manganese deposit with a high concentration of 20% to 40%. Coinciding with World War I, open-pit mining operations began at the mine the same year, supplying the United States military with manganese for military equipment such as steel combat helmets. As the war ended in 1918, demand for manganese decreased significantly and the mine remained almost dormant for two decades until World War II reignited the demand for the component. A mill for processing manganese at the site of the mine was constructed in 1942 to help meet the demand f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Environmental Remediation
Environmental remediation deals with the removal of pollution or contaminants from environmental media such as soil, groundwater, sediment, or surface water. Remedial action is generally subject to an array of regulatory requirements, and may also be based on assessments of human health and ecological risks where no legislative standards exist, or where standards are advisory. Remediation standards In the United States, the most comprehensive set of Preliminary Remediation Goals (PRGs) is from the Environmental Protection Agency (EPA) ''Regional Screening Levels'' (RSLs). A set of standards used in Europe exists and is often called the Dutch standards. The European Union (EU) is rapidly moving towards Europe-wide standards, although most of the industrialised nations in Europe have their own standards at present. In Canada, most standards for remediation are set by the provinces individually, but the Canadian Council of Ministers of the Environment provides guidance at a fed ...

Petroleum
Petroleum, also known as crude oil, or simply oil, is a naturally occurring yellowish-black liquid mixture of mainly hydrocarbons, and is found in geological formations. The name ''petroleum'' covers both naturally occurring unprocessed crude oil and petroleum products that consist of refined crude oil. A fossil fuel, petroleum is formed when large quantities of dead organisms, mostly zooplankton and algae, are buried underneath sedimentary rock and subjected to both prolonged heat and pressure. Petroleum is primarily recovered by oil drilling. Drilling is carried out after studies of structural geology, sedimentary basin analysis, and reservoir characterisation. Recent developments in technologies have also led to exploitation of other unconventional reserves such as oil sands and oil shale. Once extracted, oil is refined and separated, most easily by distillation, into innumerable products for direct use or use in manufacturing. Products include fuels such as gasolin ...

Arsenic
Arsenic is a chemical element with the symbol As and atomic number 33. Arsenic occurs in many minerals, usually in combination with sulfur and metals, but also as a pure elemental crystal. Arsenic is a metalloid. It has various allotropes, but only the gray form, which has a metallic appearance, is important to industry. The primary use of arsenic is in alloys of lead (for example, in car batteries and ammunition). Arsenic is a common n-type dopant in semiconductor electronic devices. It is also a component of the III-V compound semiconductor gallium arsenide. Arsenic and its compounds, especially the trioxide, are used in the production of pesticides, treated wood products, herbicides, and insecticides. These applications are declining with the increasing recognition of the toxicity of arsenic and its compounds. A few species of bacteria are able to use arsenic compounds as respiratory metabolites. Trace quantities of arsenic are an essential dietary element in rats, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Unanimous Consent
In parliamentary procedure, unanimous consent, also known as general consent, or in the case of the parliaments under the Westminster system, leave of the house (or leave of the senate), is a situation in which no member present objects to a proposal. Purpose Generally, in a meeting of a deliberative assembly, business is conducted using a formal procedure of motion, debate, and vote. However, if there are no objections, action could be taken by unanimous consent. The procedure of asking for unanimous consent is used to expedite business by eliminating the need for formal votes on routine questions in which the existence of a consensus is likely. The principle behind it is that procedural safeguards designed to protect a minority can be waived when there is no minority to protect. In non-legislative deliberative bodies operating under ''Robert's Rules of Order'', unanimous consent is often used to expedite the consideration of uncontroversial motions. It is sometimes used simp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
