paragraph_text: Charge is the fundamental property of forms of matter that exhibit electrostatic attraction or repulsion in the presence of other matter. Electric charge is a characteristic property of many subatomic particles. The charges of free - standing particles are integer multiples of the elementary charge e; we say that electric charge is quantized. Michael Faraday, in his electrolysis experiments, was the first to note the discrete nature of electric charge. Robert Millikan's oil drop experiment demonstrated this fact directly, and measured the elementary charge. It has been discovered that one type of particle, quarks, have fractional charges of either − 1 / 3 or + 2 / 3, but it is believed they always occur in multiples of integral charge; free - standing quarks have never been observed.

paragraph_text: The Uvac () is an international trans-boundary river, rising under Golija mountain and Pešter plateau, then flowing through southwestern Serbia and cross into eastern Bosnia and Herzegovina where, after 115 km, finally meets the Lim river from the right, however, before it empties into the Lim, for a 10 kilometers Uvac forms the border between two countries. Also, while meandering through Serbia, Uvac loosely makes the northern border of the Raška region too.

paragraph_text: Two types of charging port exist: the charging downstream port (CDP), supporting data transfers as well, and the dedicated charging port (DCP), without data support. A portable device can recognize the type of USB port; on a dedicated charging port, the D+ and D− pins are shorted with a resistance not exceeding 200 ohms, while charging downstream ports provide additional detection logic so their presence can be determined by attached devices. (see ref pg. 2, Section 1.4.5, & Table 5-3 "Resistances"—pg. 29).

paragraph_text: The plum pudding model is one of several scientific models of the atom. First proposed by J.J. Thomson in 1904 soon after the discovery of the electron, but before the discovery of the atomic nucleus, the model represented an attempt to consolidate the known properties of atoms at the time: 1) electrons are negatively - charged particles and 2) atoms are neutrally - charged.

paragraph_text: ``The Deck of Cards ''is a recitation song that was popularized in the fields of both the country and popular music, first during the late 1940s. This song, which relates the tale of a young American soldier arrested and charged with playing cards during a church service, first became a hit in the U.S. in 1948 by country musician T. Texas Tyler.

paragraph_text: In the 19th century, the mass - to - charge ratios of some ions were measured by electrochemical methods. In 1897, the mass - to - charge ratio of the electron was first measured by J.J. Thomson. By doing this, he showed that the electron was in fact a particle with a mass and a charge, and that its mass - to - charge ratio was much smaller than that of the hydrogen ion H. In 1898, Wilhelm Wien separated ions (canal rays) according to their mass - to - charge ratio with an ion optical device with superimposed electric and magnetic fields (Wien filter). In 1901 Walter Kaufman measured the increase of electromagnetic mass of fast electrons (Kaufmann -- Bucherer -- Neumann experiments), or relativistic mass increase in modern terms. In 1913, Thomson measured the mass - to - charge ratio of ions with an instrument he called a parabola spectrograph. Today, an instrument that measures the mass - to - charge ratio of charged particles is called a mass spectrometer.

paragraph_text: Domino's Pizza is credited with popularizing free pizza delivery in the United States. Pizza Hut began experimenting in 1999 with a 50 - cent delivery charge in ten stores in the Dallas - Fort Worth area. By mid-2001 it was implemented in 95% of its 1,749 company - owned restaurants in the U.S., and in a smaller number of its 5,250 franchisee - owned restaurants. By 2002, a small percentage of stores owned or franchised by U.S. pizza companies Domino's and Papa John's were also charging delivery fees of 50 cents to $1.50, and some of Little Caesar's franchisees charged delivery fees. In 2005, Papa John's implemented delivery charges in the majority of its company - owned stores.

paragraph_text: Cardigan formed up his unit and charged the length of the Valley of the Balaclava, under fire from Russian batteries in the hills. The charge of the Light Brigade caused 278 casualties of the 700-man unit. The Light Brigade was memorialized in the famous poem by Alfred Lord Tennyson, "The Charge of the Light Brigade." Although traditionally the charge of the Light Brigade was looked upon as a glorious but wasted sacrifice of good men and horses, recent historians say that the charge of the Light Brigade did succeed in at least some of its objectives. The aim of any cavalry charge is to scatter the enemy lines and frighten the enemy off the battlefield. The charge of the Light Brigade had so unnerved the Russian cavalry, which had previously been routed by the Heavy Brigade, that the Russian Cavalry was set to full-scale flight by the subsequent charge of the Light Brigade.:252

paragraph_text: The USB Battery Charging Specification Revision 1.1 (released in 2007) defines a new type of USB port, called the charging port. Contrary to the standard downstream port, for which current draw by a connected portable device can exceed 100 mA only after digital negotiation with the host or hub, a charging port can supply currents between 500 mA and 1.5 A without the digital negotiation. A charging port supplies up to 500 mA at 5 V, up to the rated current at 3.6 V or more, and drops its output voltage if the portable device attempts to draw more than the rated current. The charger port may shut down if the load is too high.

paragraph_text: The official post office was created in 1792 as the Post Office Department (USPOD). It was based on the Constitutional authority empowering Congress ``To establish post offices and post roads ''. The 1792 law provided for a greatly expanded postal network, and served editors by charging newspapers an extremely low rate. The law guaranteed the sanctity of personal correspondence, and provided the entire country with low - cost access to information on public affairs, while establishing a right to personal privacy.

paragraph_text: Tuition fees were first introduced across the entire United Kingdom in September 1998 under the Labour government as a means of funding tuition to undergraduate and postgraduate certificate students at universities, with students being required to pay up to £1,000 a year for tuition. However, as a result of the establishment of devolved national administrations for Scotland, Wales and Northern Ireland, different arrangements now exist with regard to the charging of tuition fees in each of the countries of the United Kingdom.

paragraph_text: The Republic of the Congo received full independence from France on August 15, 1960. Fulbert Youlou ruled as the country's first president until labour elements and rival political parties instigated a three-day uprising that ousted him. The Congolese military took charge of the country briefly and installed a civilian provisional government headed by Alphonse Massamba-Débat.

paragraph_text: In the United States, there has been a push to legalize importation of medications from Canada and other countries, in order to reduce consumer costs. While in most cases importation of prescription medications violates Food and Drug Administration (FDA) regulations and federal laws, enforcement is generally targeted at international drug suppliers, rather than consumers. There is no known case of any U.S. citizens buying Canadian drugs for personal use with a prescription, who has ever been charged by authorities.

paragraph_text: Italy became a major industrialized country again, due to its post-war economic miracle. The European Union (EU) involved the division of powers, with taxation, health and education handled by the nation states, while the EU had charge of market rules, competition, legal standards and environmentalism. The Soviet economic and political system collapsed, leading to the end of communism in the satellite countries in 1989, and the dissolution of the Soviet Union itself in 1991. As a consequence, Europe's integration deepened, the continent became depolarised, and the European Union expanded to subsequently include many of the formerly communist European countries – Romania and Bulgaria (2007) and Croatia (2013).
