Roland Garros 2012 Ballkid
Roland (; ; or ''Rotholandus''; or ''Rolando''; died 15 August 778) was a Frankish military leader under Charlemagne who became one of the principal figures in the literary cycle known as the Matter of France. The historical Roland was military governor of the Breton March, responsible for defending Francia's frontier against the Bretons. His only historical attestation is in Einhard's ''Vita Karoli Magni'', which notes he was part of the Frankish rearguard killed in retribution by the Basques in Iberia at the Battle of Roncevaux Pass. The story of Roland's death at Roncevaux Pass was embellished in later medieval and Renaissance literature. The first and most famous of these epic treatments was the Old French ''Chanson de Roland">-4; we might wonder whether there's a point at which it's appropriate to talk of the beginnings of French, that is, when it wa ...

Sea-level
Mean sea level (MSL, often shortened to sea level) is an average surface level of one or more among Earth's coastal bodies of water from which heights such as elevation may be measured. The global MSL is a type of vertical datuma standardised geodetic datumthat is used, for example, as a chart datum in cartography and marine navigation, or, in aviation, as the standard sea level at which atmospheric pressure is measured to calibrate altitude and, consequently, aircraft flight levels. A common and relatively straightforward mean sea-level standard is instead a long-term average of tide gauge readings at a particular reference location. The term ''above sea level'' generally refers to the height above mean sea level (AMSL). The term APSL means above present sea level, comparing sea levels in the past with the level today. Earth's radius at sea level is 6,378.137 km (3,963.191 mi) at the equator. It is 6,356.752 km (3,949.903 mi) at the poles and 6,371.001&nbs ...

Dice
A die (: dice, sometimes also used as ) is a small, throwable object with marked sides that can rest in multiple positions. Dice are used for generating random values, commonly as part of tabletop games, including dice games, board games, role-playing games, and games of chance. A traditional die is a cube with each of its six faces marked with a different number of dots ( pips) from one to six. When thrown or rolled, the die comes to rest showing a random integer from one to six on its upper surface, with each value being equally likely. Dice may also have other polyhedral or irregular shapes, may have faces marked with numerals or symbols instead of pips and may have their numbers carved out from the material of the dice instead of marked on it. Loaded dice are specifically designed or modified to favor some results over others, for cheating or entertainment purposes. History Dice have been used since before recorded history, and their origin is uncertain. It is hypoth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Playing Card
A playing card is a piece of specially prepared card stock, heavy paper, thin cardboard, plastic-coated paper, cotton-paper blend, or thin plastic that is marked with distinguishing motifs. Often the front (face) and back of each card has a finish to make handling easier. They are most commonly used for playing card games, and are also used in magic tricks, cardistry, card throwing, and card houses; cards may also be collected. Playing cards are typically palm-sized for convenient handling, and usually are sold together in a set as a deck of cards or pack of cards. The most common type of playing card in the West is the French-suited, standard 52-card pack, of which the most widespread design is the English pattern, followed by the Belgian-Genoese pattern. However, many countries use other, traditional types of playing card, including those that are German, Italian, Spanish and Swiss-suited.

Tennis Balls, Advertisement, 19th Century
Tennis is a racket sport that is played either individually against a single opponent (singles) or between two teams of two players each ( doubles). Each player uses a tennis racket strung with a cord to strike a hollow rubber ball covered with felt over or around a net and into the opponent's court. The object is to manoeuvre the ball in such a way that the opponent is not able to play a valid return. If a player is unable to return the ball successfully, the opponent scores a point. Playable at all levels of society and at all ages, tennis can be played by anyone who can hold a racket, including wheelchair users. The original forms of tennis developed in France during the late Middle Ages. The modern form of tennis originated in Birmingham, England, in the late 19th century as lawn tennis. It had close connections to various field (lawn) games such as croquet and bowls as well as to the older racket sport today called real tennis. The rules of modern tennis have changed li ...

Statute Law Revision (Ireland) Act 1872
Statute law revision may refer to the printing of, or the editorial process of preparing, a revised edition of the statutes, or to the process of repealing obsolete enactments to facilitate the preparation of such an edition, or to facilitate the consolidation of enactments. United Kingdom History In the United Kingdom, acts of Parliament remain in force until expressly repealed. Consolidation of the statute book has been discussed since at least the 16th-century and the reformation. Early efforts In 1549, the House of Commons sent a proposal to the House of Lords that the statute law "should be digested into a body under titles and heads and put into good Latin", in imitation of Roman law. In 1551, in his ''Discourse on the Reformation of Abuses,'' King Edward VI, then aged 14, wrote: These efforts, culminating in a proposal for bringing common law into the statute law, were observed by Bishop Burnet as "too great a design to be set on foot or finished under an infant ...

Statute Law Revision Act 1863
A statute is a law or formal written enactment of a legislature. Statutes typically declare, command or prohibit something. Statutes are distinguished from court law and unwritten law (also known as common law) in that they are the expressed will of a legislative body, whether that be on the behalf of a country, state or province, county, municipality, or so on. Depending on the legal system, a statute may also be referred to as an "act." Etymology The word appears in use in English as early as the 14th century. "Statute" and earlier English spellings were derived from the Old French words ''statut'', ''estatut'', ''estatu,'' meaning "(royal) promulgation, (legal) statute." These terms were in turn derived from the Late Latin ''statutum,'' meaning "a law, decree." Publication and organization In virtually all countries, newly enacted statutes are published and distributed so that everyone can look up the statutory law. This can be done in the form of a government gazette, whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Repeal Of Acts Concerning Importation Act 1822
The Repeal of Acts Concerning Importation Act 1822 ( 3 Geo. 4. c. 41) was an act of the Parliament of the United Kingdom that repealed enactments relating to navigation in the United Kingdom. Background In the United Kingdom, acts of Parliament remain in force until expressly repealed. Blackstone's ''Commentaries on the Laws of England'', published in the late 18th-century, raised questions about the system and structure of the common law and the poor drafting and disorder of the existing statute book. In 1806, the Commission on Public Records passed a resolution requesting the production of a report on the best mode of reducing the volume of the statute book. From 1810 to 1825, ''The Statutes of the Realm'' was published, providing for the first time the authoritative collection of acts. By the early 19th-century, British customs law, relating to trade, navigation, the import and export of goods, and the collection of customs revenue, had become increasingly intricate ...
