Selena albums discography

American singer Selena has released five studio albums, three live albums, one soundtrack and twenty-one compilation albums. Credited for elevating a music genre into the mainstream market, Selena remains the best-selling Tejano recording artist whose posthumous releases continue to outsell those of living musicians. As of 2015, the singer has sold 60 million copies worldwide, and was named the "Top Latin Artist of the '90s" and "Best-selling Latin Artist of the Decade" by Billboard magazine. In 1995, Selena was inducted into the Billboard Latin Music Hall of Fame, the Hard Rock Cafe's Hall of Fame, the South Texas Music Hall of Fame, and the Tejano Music Hall of Fame in 2001.

Selena's career began as lead vocalist of Los Dinos in 1980. She signed with EMI Latin nine years later as a solo artist though her band continued to tour with her. She released her self-titled debut album that same year, which peaked at number seven on the U.S. Billboard Regional Mexican Albums chart. With Selena, the singer outsold other female Tejano artists. She released her second album Ven Conmigo in October 1990; it peaked at number three on the Regional Mexican Albums chart. Ven Conmigo was later certified gold by the Recording Industry Association of America (RIAA) for shipments of 50,000 units, the first recording by a female Tejano artist to do so. As of 2010, Ven Conmigo had sold 500,000 copies in the United States. According to music critics, her next recording Entre a Mi Mundo (1992), was the "breakthrough album" of her musical career. The album and its lead single, "Como la Flor", helped launch the singer's career in Mexico.Entre a Mi Mundo peaked at number one on the Regional Mexican Albums chart for eight consecutive months; and was certified 6× platinum by the RIAA, signifying shipments of 600,000 units. Entre a Mi Mundo became the first Tejano recording by a female artist to sell over 300,000 copies.

Limited Edition (Magic: The Gathering)

Magic: The Gathering Limited Edition is the first Magic: The Gathering card set. It premiered in a limited release at Origins Game Fair in 1993, with a general release that August. The initial print run of 2.6 million cards sold out quickly, and a new printing run was released in October 1993. These two runs are known as Limited Edition Alpha and Limited Edition Beta, or just Alpha and Beta for short. Although Alpha and Beta are referred to as different sets by some, officially they are the same set; Wizards of the Coast had expected that people wouldn't necessarily be able to tell the two press runs apart. Beta fixed a number of misprints and errors on cards. The printer accidentally used different corner rounding dies for the second run, resulting in Alpha cards being noticeably distinct in shape and appearance from Beta cards and all subsequent cards. The Beta printing also included a revised rulebook with a number of clarifications, although creator Richard Garfield's short fiction "Worzel's Tale" was removed to make room. The print run of Beta is given as 7.3 million or 7.8 million depending on the source. Despite the set's print run being about three times as big as Alpha's, Beta sold out as quickly as its predecessor.

Condenser (microscope)

A condenser is one of the main components of the optical system of many transmitted light compound microscopes. A condenser is a lens that serves to concentrate light from the illumination source that is in turn focused through the object and magnified by the objective lens. It is a basic component of almost all compound light microscopes manufactured since the 19th Century. An equivalent condenser, which focuses an electron beam, is a basic component of both transmission and scanning electron microscopes.

Description

Condensers are located above the light source and under the sample in an upright microscope, and above the stage and below the light source in an inverted microscope. They act to gather light from the microscope's light source and concentrate it into a cone of light that illuminates the specimen. The aperture and angle of the light cone must be adjusted (via the size of the diaphragm) for each different objective lens with different numerical apertures.

Condenser (laboratory)

A condenser is an apparatus or item of equipment used to condense (change the physical state of) a substance from its gaseous to its liquid state. In the laboratory, condensers are generally used in procedures done with organic liquids brought into gaseous state through heating with or without lowering the pressure (applying vacuum)—though applications in inorganic and other chemistry areas exist. While condensers can be applied at various scales, in the research, training, or discovery laboratory, one most often uses glassware designed to pass a vapor flow over an adjacent cooled chamber. In simplest form, such a condenser consists of a single glass tube with outside air providing cooling. A further simple form, the Liebig-type of condenser, involves concentric glass tubes, an inner one through which the hot gases pass, and an outer, "ported" chamber through which a cooling fluid passes, to reduce the gas temperature in the inner, to afford the condensation.
