paragraph_text: The Occupation of the Ruhr (German: Ruhrbesetzung) was a period of military occupation of the German Ruhr valley by France and Belgium between 1923 and 1925 in response to the Weimar Republic's failure to continue its reparation payments in the aftermath of World War I.

paragraph_text: An electric field is a field that surrounds electric charges. It represents charges attracting or repelling other electric charges by exerting force. Mathematically the electric field is a vector field that associates to each point in space the force, called the Coulomb force, that would be experienced per unit of charge, by an infinitesimal test charge at that point. The units of the electric field in the SI system are newtons per coulomb (N / C), or volts per meter (V / m). Electric fields are created by electric charges, and by time - varying magnetic fields. Electric fields are important in many areas of physics, and are exploited practically in electrical technology. On an atomic scale, the electric field is responsible for the attractive force between the atomic nucleus and electrons that holds atoms together, and the forces between atoms that cause chemical bonding. The electric field and the magnetic field together form the electromagnetic force, one of the four fundamental forces of nature.

paragraph_text: Calderón (pronounced (kaldeˈɾon)) is a Spanish occupational surname. It is derived from the Vulgar Latin ``caldaria ''(`` cauldron'') and refers to the occupation of tinker.

paragraph_text: The current I(t) through any component in an electric circuit is defined as the rate of flow of a charge Q(t) passing through it, but actual charges—electrons—cannot pass through the dielectric layer of a capacitor. Rather, one electron accumulates on the negative plate for each one that leaves the positive plate, resulting in an electron depletion and consequent positive charge on one electrode that is equal and opposite to the accumulated negative charge on the other. Thus the charge on the electrodes is equal to the integral of the current as well as proportional to the voltage, as discussed above. As with any antiderivative, a constant of integration is added to represent the initial voltage V(t0). This is the integral form of the capacitor equation:

paragraph_text: Through combining the definition of electric current as the time rate of change of electric charge, a rule of vector multiplication called Lorentz's Law describes the force on a charge moving in a magnetic field. The connection between electricity and magnetism allows for the description of a unified electromagnetic force that acts on a charge. This force can be written as a sum of the electrostatic force (due to the electric field) and the magnetic force (due to the magnetic field). Fully stated, this is the law:

paragraph_text: The occupation of the Baltic states was the military occupation of the three Baltic states -- Estonia, Latvia and Lithuania -- by the Soviet Union under the auspices of the Molotov -- Ribbentrop Pact on 14 June 1940 followed by their incorporation into the USSR as constituent republics, unrecognised by most Western powers. On 22 June 1941, Nazi Germany attacked the USSR and within weeks occupied the Baltic territories. In July 1941, the Baltic territory was incorporated into the Reichskommissariat Ostland of the Third Reich. As a result of the Baltic Offensive of 1944, the Soviet Union recaptured most of the Baltic states and trapped the remaining German forces in the Courland pocket until their formal surrender in May 1945. The Soviet ``annexation occupation ''(Annexionsbesetzung or occupation sui generis) of the Baltic states lasted until August 1991, when the Baltic states regained independence.

paragraph_text: Villa Welgelegen is a historical building in Haarlem, the Netherlands, which currently houses the offices of the provincial executives of North Holland. Located at the north end of a public park in the city, it is an example of neoclassical architecture, unusual for its style in the Netherlands.

paragraph_text: The Occupational Safety and Health Act of 1970 is a US labor law governing the federal law of occupational health and safety in the private sector and federal government in the United States. It was enacted by Congress in 1970 and was signed by President Richard Nixon on December 29, 1970. Its main goal is to ensure that employers provide employees with an environment free from recognized hazards, such as exposure to toxic chemicals, excessive noise levels, mechanical dangers, heat or cold stress, or unsanitary conditions. The Act created the Occupational Safety and Health Administration (OSHA) and the National Institute for Occupational Safety and Health (NIOSH).

paragraph_text: In 1946 Bremen's mayor Wilhelm Kaisen (SPD) travelled to the U.S. to re-establish Bremen's statehood, as Bremen had traditionally been a city-state, in order to prevent its incorporation into the state of Lower Saxony in the British zone of occupation. In 1947 the city became an enclave, part of the American occupation zone surrounded by the British zone.

paragraph_text: The Shanghai Bull, the Bund Financial Bull or the Bund Bull are monikers associated with a derivative of Arturo Di Modica's "Charging Bull" installed in late April 2010 and unveiled on The Bund in Shanghai on May 15, 2010. The work of art is said to have the same height, length and weight as the New York City "Charging Bull". The bull is reddish as a tribute to the country that commissioned the work. It leans to right instead of the left like "Charging Bull" and has a more menacing tail. The Bull's popularity has been a problem for local authorities.

paragraph_text: The Battle of Mount Longdon was an engagement of the Falklands War between the British Third Battalion, of the Parachute Regiment supported by six L118 light guns and the vessel and Argentine forces consisting of the 7th Infantry Regiment and other ad hoc additions. The engagement took place on 11–12 June 1982, a mixture of hand-to-hand bayonet charges and ranged engagments, resulting in the British victory and their occupation of a key position around the besieged Argentine garrison at Port Stanley.

paragraph_text: During World War II, Imperial Japan invaded most of the former western colonies. The Shōwa occupation regime committed violent actions against civilians such as the Manila massacre and the implementation of a system of forced labour, such as the one involving 4 to 10 million romusha in Indonesia. A later UN report stated that four million people died in Indonesia as a result of famine and forced labour during the Japanese occupation. The Allied powers who defeated Japan in the South-East Asian theatre of World War II then contended with nationalists to whom the occupation authorities had granted independence.

paragraph_text: The Occupation of Gori was the military occupation of Gori and its surrounding areas by Russian military forces, which started on 13 August 2008 as part of the Russo-Georgian War, and ended with the withdrawal of Russian units from the city on 22 August 2008.

paragraph_text: The nucleus was discovered in 1911, as a result of Ernest Rutherford's efforts to test Thomson's ``plum pudding model ''of the atom. The electron had already been discovered earlier by J.J. Thomson himself. Knowing that atoms are electrically neutral, Thomson postulated that there must be a positive charge as well. In his plum pudding model, Thomson suggested that an atom consisted of negative electrons randomly scattered within a sphere of positive charge. Ernest Rutherford later devised an experiment with his research partner Hans Geiger and with help of Ernest Marsden, that involved the deflection of alpha particles (helium nuclei) directed at a thin sheet of metal foil. He reasoned that if Thomson's model were correct, the positively charged alpha particles would easily pass through the foil with very little deviation in their paths, as the foil should act as electrically neutral if the negative and positive charges are so intimately mixed as to make it appear neutral. To his surprise, many of the particles were deflected at very large angles. Because the mass of an alpha particle is about 8000 times that of an electron, it became apparent that a very strong force must be present if it could deflect the massive and fast moving alpha particles. He realized that the plum pudding model could not be accurate and that the deflections of the alpha particles could only be explained if the positive and negative charges were separated from each other and that the mass of the atom was a concentrated point of positive charge. This justified the idea of a nuclear atom with a dense center of positive charge and mass.

paragraph_text: The capital and seat of the provincial government is Haarlem, and the province's largest city is the Netherlands' capital Amsterdam. The King's Commissioner of North Holland is Johan Remkes, serving since 2010. There are 51 municipalities and three (including parts of) water boards in the province.

paragraph_text: Sleep-and-charge USB ports can be used to charge electronic devices even when the computer is switched off. Normally, when a computer is powered off the USB ports are powered down, preventing phones and other devices from charging. Sleep-and-charge USB ports remain powered even when the computer is off. On laptops, charging devices from the USB port when it is not being powered from AC drains the laptop battery faster; most laptops have a facility to stop charging if their own battery charge level gets too low.

paragraph_text: After finding the quantized character of charge, in 1891 George Stoney proposed the unit 'electron' for this fundamental unit of electrical charge. This was before the discovery of the particle by J.J. Thomson in 1897. The unit is today treated as nameless, referred to as ``elementary charge '',`` fundamental unit of charge'', or simply as ``e ''. A measure of charge should be a multiple of the elementary charge e, even if at large scales charge seems to behave as a real quantity. In some contexts it is meaningful to speak of fractions of a charge; for example in the charging of a capacitor, or in the fractional quantum Hall effect.

paragraph_text: In the English NHS charges are made for prescription drugs, and the majority of adults (though not a majority of patients) are required to pay them. Charges were abolished in NHS Wales in 2007, Health and Social Care in Northern Ireland in 2010 and by NHS Scotland in 2011. In 2010 / 11, in England, £450m was raised through prescription charges, some 0.5% of the total NHS budget.

paragraph_text: The London congestion charge is a fee charged on most motor vehicles operating within the Congestion Charge Zone (CCZ) in Central London between 07: 00 and 18: 00 Mondays to Fridays. It is not charged on weekends, public holidays or between Christmas Day and New Year's Day (inclusive). The charge was introduced on 17 February 2003. As of 2017, the London charge zone remains as one of the largest congestion charge zones in the world, despite the cancellation of the Western Extension which operated between February 2007 and January 2011. The charge aims to reduce high traffic flow in the central area and raise investment funds for London's transport system.

paragraph_text: ``The Charge of the Light Brigade ''is an 1854 narrative poem by Alfred, Lord Tennyson about the Charge of the Light Brigade at the Battle of Balaclava during the Crimean War. He wrote it on December 2, 1854, and it was published on December 9, 1854 in The Examiner. He was the Poet Laureate of the United Kingdom at the time.
