Dos (Fanny Lu album)

Dos (English: Two) is the title of the second album by Colombian Pop and Vallenato singer, Fanny Lu. The album was released in Colombia on December 8, 2008, and in the United States and Puerto Rico the following week. In Colombia, Dos went straight to number one in the album charts in its debut week. The album features the lead single and the official song of the year in Colombia, "Tú No Eres Para Mi" (You Are Not For Me).

Album information

The album was greeted with huge anticipation following the success of the lead single "Tú No Eres Para Mi". The hit was number one on Colombian radio for eleven weeks. As well as this, there were high expectations considering the success of Fanny's first album, Lágrimas Cálidas (English: "Warm Tears"), which spent nine weeks at number one in Colombia. Fanny Lu produced the album and co-wrote many of the tracks, most notably "Un Minuto Más" (English: "One More Minute"), a duet with Noel Schajris. The song is a tribute to her late father who was murdered. Weeks before the release of the album, Fanny stated that "We were looking for a fusion of sounds. I didn't limit myself. I gave myself the luxury of exploring, because it was important not to repeat what I'd done. For example, many times, instead of accordions, we experimented with winds. This album is like a walk along all those genres I love, and all the songs have their own palate and color."

Shell corporation

A shell corporation is a company which serves as a vehicle for business transactions without itself having any significant assets or operations. Some shell companies may have had operations, but those may have shrunk due to unfavorable market conditions or company mismanagement. A shell corporation may also arise when a company's operations have been wound up, for example following a takeover, but the “shell” of the original company continues to exist.

Shell corporations are not in themselves illegal, and they do have legitimate business purposes. However, they are a main component of the underground economy, especially those based in tax havens. They may also be known as international business companies, personal investment companies, front companies, or "mailbox" companies.

Shell companies can also be used for tax avoidance. A classic tax avoidance operation is based on the buying and selling through tax haven shell companies to disguise true profits. The firm does its international operations through this shell corporation, thus not having to report to its country the sums involved, avoiding any taxes.

Shell Oil Company

Shell Oil Company is the United States-based subsidiary of Royal Dutch Shell, a multinational "oil major" of Anglo-Dutch origins, which is amongst the largest oil companies in the world. Approximately 22,000 Shell employees are based in the U.S. The U.S. head office is in Houston, Texas. Shell Oil Company, including its consolidated companies and its share in equity companies, is one of America's largest oil and natural gas producers, natural gas marketers, gasoline marketers and petrochemical manufacturers.

Shell is the market leader through approximately 25,000 Shell-branded gas stations in the U.S. which also serve as Shell's most visible public presence. Shell Oil Company is a 50/50 partner with the Saudi Arabian government-owned oil company Saudi Aramco in Motiva Enterprises, a refining and marketing joint venture which owns and operates three oil refineries on the Gulf Coast of the United States.

Shell products include oils, fuels, and card services as well as exploration, production, and refining of petroleum products. The Shell Oil Refinery in Martinez, California, the first Shell refinery in the United States, supplies Shell and Texaco stations in the West and Midwest.

CONFIG.SYS

CONFIG.SYS is the primary configuration file for the DOS and OS/2 operating systems. It is a special ASCII text file that contains user-accessible setup or configuration directives evaluated by the operating system during boot. CONFIG.SYS was introduced with DOS 2.0.

Usage

The directives in this file configure DOS for use with devices and applications in the system. The CONFIG.SYS directives also set up the memory managers in the system. After processing the CONFIG.SYS file, DOS proceeds to load and execute the command shell specified in the SHELL line of CONFIG.SYS, or COMMAND.COM if there is no such line. The command shell in turn is responsible for processing the AUTOEXEC.BAT file.

CONFIG.SYS is composed mostly of name=value directives which look like variable assignments. In fact, these will either define some tunable parameters often resulting in reservation of memory, or load files, mostly device drivers and TSRs, into memory.

In DOS, CONFIG.SYS is located in the root directory of the drive from which the system was booted.
