Public School District
A school district is a special-purpose district that operates local public Primary school, primary and Secondary school, secondary schools in various nations. North America United States In the U.S, most K–12 public schools function as units of local school districts, which usually operate several schools, and the largest urban and suburban districts operate hundreds of schools. While practice varies significantly by state (and in some cases, within a state), most American school districts operate as independent local governmental units under a grant of authority and within geographic limits created by state law. The executive and legislative power over locally controlled policies and operations of an independent school district are, in most cases, held by a school district's board of education. Depending on state law, members of a local board of education (often referred to informally as a school board) may be elected, appointed by a political office holder, serve ex offic ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radium
Radium is a chemical element with the symbol Ra and atomic number 88. It is the sixth element in group 2 of the periodic table, also known as the alkaline earth metals. Pure radium is silvery-white, but it readily reacts with nitrogen (rather than oxygen) upon exposure to air, forming a black surface layer of radium nitride (Ra3N2). All isotopes of radium are radioactive, the most stable isotope being radium-226 with a half-life of 1600 years. When radium decays, it emits ionizing radiation as a by-product, which can excite fluorescent chemicals and cause radioluminescence. Radium, in the form of radium chloride, was discovered by Marie and Pierre Curie in 1898 from ore mined at Jáchymov. They extracted the radium compound from uraninite and published the discovery at the French Academy of Sciences five days later. Radium was isolated in its metallic state by Marie Curie and André-Louis Debierne through the electrolysis of radium chloride in 1911. In nature, radium is found ...

Polonium
Polonium is a chemical element with the symbol Po and atomic number 84. Polonium is a chalcogen. A rare and highly radioactive metal with no stable isotopes, polonium is chemically similar to selenium and tellurium, though its metallic character resembles that of its horizontal neighbors in the periodic table: thallium, lead, and bismuth. Due to the short half-life of all its isotopes, its natural occurrence is limited to tiny traces of the fleeting polonium-210 (with a half-life of 138 days) in uranium ores, as it is the penultimate daughter of natural uranium-238. Though slightly longer-lived isotopes exist, they are much more difficult to produce. Today, polonium is usually produced in milligram quantities by the neutron irradiation of bismuth. Due to its intense radioactivity, which results in the radiolysis of chemical bonds and radioactive self-heating, its chemistry has mostly been investigated on the trace scale only. Polonium was discovered in July 1898 by Marie SkÅ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isotopes Of Lead
Lead (82Pb) has four stable isotopes: 204Pb, 206Pb, 207Pb, 208Pb. Lead-204 is entirely a primordial nuclide and is not a radiogenic nuclide. The three isotopes lead-206, lead-207, and lead-208 represent the ends of three decay chains: the uranium series (or radium series), the actinium series, and the thorium series, respectively; a fourth decay chain, the neptunium series, terminates with the thallium isotope 205Tl. The three series terminating in lead represent the decay chain products of long-lived primordial 238U, 235U, and 232Th, respectively. However, each of them also occurs, to some extent, as primordial isotopes that were made in supernovae, rather than radiogenically as daughter products. The fixed ratio of lead-204 to the primordial amounts of the other lead isotopes may be used as the baseline to estimate the extra amounts of radiogenic lead present in rocks as a result of decay from uranium and thorium. (See lead–lead dating and uranium–lead dating). The longes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Employment Discrimination
Employment discrimination is a form of illegal discrimination in the workplace based on legally protected characteristics. In the U.S., federal anti-discrimination law prohibits discrimination by employers against employees based on age, race, gender, sex (including pregnancy, sexual orientation, and gender identity), religion, national origin, and physical or mental disability. State and local laws often protect additional characteristics such as marital status, veteran status and caregiver/familial status. Earnings differentials or occupational differentiation—where differences in pay come from differences in qualifications or responsibilities—should not be confused with employment discrimination. Discrimination can be intended and involve disparate treatment of a group or be unintended, yet create disparate impact for a group. Definition In neoclassical economics theory, labor market discrimination is defined as the different treatment of two equally qualified individu ...

First Amendment To The United States Constitution
The First Amendment (Amendment I) to the United States Constitution prevents the government from making laws that regulate an establishment of religion, or that prohibit the free exercise of religion, or abridge the freedom of speech, the freedom of the press, the freedom of assembly, or the right to petition the government for redress of grievances. It was adopted on December 15, 1791, as one of the ten amendments that constitute the Bill of Rights. The Bill of Rights was proposed to assuage Anti-Federalist opposition to Constitutional ratification. Initially, the First Amendment applied only to laws enacted by the Congress, and many of its provisions were interpreted more narrowly than they are today. Beginning with ''Gitlow v. New York'' (1925), the Supreme Court applied the First Amendment to states—a process known as incorporation—through the Due Process Clause of the Fourteenth Amendment. In '' Everson v. Board of Education'' (1947), the Court drew on Thomas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forum (legal)
In United States constitutional law, a forum is a property that is open to public expression and assembly. Types Forums are classified as public or nonpublic. Public forum A public forum also called an ''open forum'', is open to all expression that is protected under the First Amendment. Streets, parks, and sidewalks are considered open to public discourse by tradition and are designated as ''traditional public forums''. The government creates a ''designated public forum'' when it intentionally opens a nontraditional forum for public discourse''. Limited public forums'', such as municipal meeting rooms, are nonpublic forums that have been specifically designated by the government as open to certain groups or topics. Traditional public forums cannot be changed to nonpublic forums by governments. The use of public forums generally cannot be restricted based on the content of the speech expressed by the user. Use can be restricted based on content, however, if the restriction passe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Newspaper
A newspaper is a periodical publication containing written information about current events and is often typed in black ink with a white or gray background. Newspapers can cover a wide variety of fields such as politics, business, sports and art, and often include materials such as opinion columns, weather forecasts, reviews of local services, obituaries, birth notices, crosswords, editorial cartoons, comic strips, and advice columns. Most newspapers are businesses, and they pay their expenses with a mixture of subscription revenue, newsstand sales, and advertising revenue. The journalism organizations that publish newspapers are themselves often metonymically called newspapers. Newspapers have traditionally been published in print (usually on cheap, low-grade paper called newsprint). However, today most newspapers are also published on websites as online newspapers, and some have even abandoned their print versions entirely. Newspapers developed in the 17th century ...

Public School (government Funded)
State schools (in England, Wales, Australia and New Zealand) or public schools (Scottish English and North American English) are generally primary or secondary schools that educate all students without charge. They are funded in whole or in part by taxation. State funded schools exist in virtually every country of the world, though there are significant variations in their structure and educational programmes. State education generally encompasses primary and secondary education (4 years old to 18 years old). By country Africa South Africa In South Africa, a state school or government school refers to a school that is state-controlled. These are officially called public schools according to the South African Schools Act of 1996, but it is a term that is not used colloquially. The Act recognised two categories of schools: public and independent. Independent schools include all private schools and schools that are privately governed. Independent schools with low tui ...
