Most dolmen constructions they were build using stone slabs of big dimensions. Their architecture often includes a corridor of access that can be constructed usins stone slabs or dry stones. The burial chamber, with variable shapes (rectangular, polygonal, oval, circular ...) can also be preceded by an anteroom. In some dolmens, the entrance has a door cut into one or more vertical stone slabs.
The main applications of the slabs as material of construction are for pavings and in the construction of roofs. But they can be employed for other uses, among them:
A system to cook the foods is “to the slab”. In like manner to the systems of “to the iron” or “grilled”, in the procedure to bake to the slab the foods course (meat, fish, vegetables...) They put on a slab hot on of the fire. With oil, butter or lard and all the aditaments with that want to dress the teak.
From prehistoric times there are examples of graves covered with a stone slab, in its natural state or carved. This use as tombstone has extended the concept of natural slab to the tombstone variant: flat, thin and polished. Example: the tomb of King Peter the Great,
The tombstones use to have some inscriptions. The information on the stone slab traditionally includes the name of the deceased and his date of birth and death. The inscriptions are generally in the frontal side of the stone slab but also in some cases in the verso and around the edges of the slab, some families request to write an inscription in the unseen part of the stone slab (oriented to the ground). Apart from the name, some slabs also have epitaphs in praise of the deceased or citations of religious texts, as "Requiescat in pace".
Marecchia
The Marecchia () is a river of the Emilia-Romagna region. The city of Rimini gets its name from the Latin name of the river.
Its low course marks the end of the Padan Plain ().
The Marecchia river has a length of , and a drainage basin with an area of approximately .
Its discharge (volume of water which passes through a section of the river per unit of time) depends of the season: in the autumn could be as high as but is very low during summer. Most of the time, the discharge is about .
The Marecchia river flows through a valley named after it, "Valmarecchia". The river starts at about west of "Viamaggio" ("comune" of Pieve Santo Stefano) and about southwest of the "comune" of Badia Tedalda, in the province of Arezzo (Tuscany), in the "Alpe della Luna" at an elevation of above sea level.
At about to the northeast of Badia Tedalda, the river gets into the Emilia-Romagna region, in the Casteldelci "comune", province of Rimini. Then it flows through Ca 'Raffaello, an exclave of Badia Tedalda; to the north of here, the Senatello river flows into the Marecchia as a left tributary. Later, in "Ponte Masa", the Masa river flows from the right into the Marecchia.
Shortly after "Torello", the San Marino river flows as a right tributary and, after the Verucchio "comune", the Ausa flows also from the right.
Between the "frazioni" (Italian subdivisions of a municipality) of "Rivabella" and "San Giuliano", in Rimini, the Marecchia river ends in the Adriatic Sea.
The Bridge of Tiberius () or Bridge of Augustus () is a Roman bridge in Rimini. Its construction began in times of Augustus but was finished in 20 AD in times of Tiberius.
The tributaries of the Marecchia river are:
Shijiazhuang
Shijiazhuang (石家庄) is the capital of the Hebei province in China.
The city is at the edge of the North China Plain. It is about southwest of Beijing.
Manchu queue
The Manchu queue or the Manchu braid was a hairstyle that all men in China during the Qing Dynasty (1644-1912) had to wear. After the overthrow of the Qing dynasty, Chinese men no longer had to wear the Manchu queue.
War bride
During war, or when a country is occupied, many people who serve in the military are present in that country. Some of these people are soldiers, other people are part of military personnel. Women who marry those people are known as war brides. The effect is well-documented for the period of the First and Second World War, but it also applies to other wars, such as the Philippine–American War, the Vietnam War, the Korean War or the Occupation of Japan.

Catenary
A catenary is a type of curve. An ideal chain hanging between two supports and acted on by a uniform gravitational force makes the shape of a catenary. (An ideal chain is one that can bend perfectly, cannot be stretched and has the same density throughout.) The supports can be at different heights and the shape will still be a catenary. A catenary looks a bit like a parabola, but they are different.
The equation for a catenary in Cartesian coordinates is
where formula_2 is a parameter that determines the shape of the catenary and is the hyperbolic cosine function, which is defined as
Hence, we can also write the catenary equation as
The word "catenary" comes from the Latin word "catena", which means "chain". A catenary is also called called an alysoid and a chainette.
Perfect information
Perfect information has different definitions depending on the field.
In economics, the term perfect information refers to an element of competition in a market which is perfect and idealized. This is commonly known as perfect competition.
In the mathematical branch of game theory, a perfect information game uses perfect information if all the actions taken in the game are known, and the state of the game's materials is available to all players. Perfect information is a type of common knowledge. Perfect information relates to the materials of the game, and to the rules of the game.
It follows that imperfect information is when elements of the game (materials or rules) are not equally available to all participants.
Perfect information games do not require that each player has a working memory of past positions but that merely they have had the opportunity to view such past actions.
In a game of chess or go, the pieces and the rules are known, but the implications of the position are not. This identifies chess as a perfect information game. In competitive card games like bridge and poker, the cards held by opponents are not known, or only partly known. They are not perfect information games.
Holon Children's Museum
Holon Children's Museum () is the first museum dedicated for children in Israel. It was opened in 2001. The museum is located in Shimon Peres Park in Holon.
Compromise of 1850
The Compromise of 1850 was a series of laws passed in 1850 that dealt with the controversial issue of slavery in the United States. As a result of the Mexican–American War, the United States acquired a great deal of new territory. The laws admitted California as a free state, and created the new territories of New Mexico and Utah. A dispute over the boundary between Texas and New Mexico was settled with Texas losing the New Mexico territory. It put an end to the slave trade in Washington, D.C. and made it easier for Southern slaveowners to recover runaway slaves. The compromise called for each new state to decide for itself whether it would be a slave or free states. The commerce and trade compromise ended the slave trade and eventually led to the Emancipation Proclamation.
