Aluminium

Aluminium (or aluminum; see different endings) is a chemical element in the boron group with symbol Al and atomic number 13. It is a silvery-white, soft, nonmagnetic, ductile metal. Aluminium is the third most abundant element (after oxygen and silicon), and the most abundant metal, in the Earth's crust. It makes up about 8% by mass of the crust, though it is less common in the mantle below. Aluminium metal is so chemically reactive that native specimens are rare and limited to extreme reducing environments. Instead, it is found combined in over 270 different minerals. The chief ore of aluminium is bauxite.

Aluminium is remarkable for the metal's low density and for its ability to resist corrosion due to the phenomenon of passivation. Structural components made from aluminium and its alloys are vital to the aerospace industry and are important in other areas of transportation and structural materials, such as building facades and window frames. The most useful compounds of aluminium, at least on a weight basis, are the oxides and sulfates.

Aluminium Nag Hammâdi

Aluminium is an Egyptian football club based in Nag Hammâdi.

The club returned to the Egyptian Premier League at the beginning of the 2007–08 season, following a long absence.

Leader of El Zamalek and former player of the Egypt national football team, Hussein Abdel Latif, managed to ascend to the league again after major conflict with the teams level. Aluminium tries in the championship this season to provide a good standard. The main goal of the group is the lack of landing once again to the league Section II with the end of the season.

Broker

A broker is an individual or party (brokerage firm) that arranges transactions between a buyer and a seller for a commission when the deal is executed. A broker who also acts as a seller or as a buyer becomes a principal party to the deal. Distinguish agent—one who acts on behalf of a principal.

Definition

A broker is an independent agent used extensively in some industries. A broker's prime responsibility is to bring sellers and buyers together and thus a broker is the third-person facilitator between a buyer and a seller. An example would be a real estate broker who facilitates the sale of a property.

Brokers also can furnish market information regarding prices, products, and market conditions. Brokers may represent either the seller (90% of the time) or the buyer (10%) but not both at the same time. An example would be a stockbroker, who makes the sale or purchase of securities on behalf of his client. Brokers play a huge role in the sale of stocks, bonds, and other financial services.

Service-oriented architecture

A service-oriented architecture (SOA) is an architectural pattern in computer software design in which application components provide services to other components via a communications protocol, typically over a network. The principles of service-orientation are independent of any vendor, product or technology.

A service is a self-contained unit of functionality, such as retrieving an online bank statement. By that definition, a service is an operation that may be discretely invoked. However, in the Web Services Description Language (WSDL), a service is an interface definition that may list several discrete services/operations. And elsewhere, the term service is used for a component that is encapsulated behind an interface. This widespread ambiguity is reflected in what follows.

Services can be combined to provide the functionality of a large software application. SOA makes it easier for software components on computers connected over a network to cooperate. Every computer can run any number of services, and each service is built in a way that ensures that the service can exchange information with any other service in the network without human interaction and without the need to make changes to the underlying program itself.
