Cestoda

Cestoda (Cestoidea) is a class of parasitic flatworms, of the phylum Platyhelminthes. Biologists informally refer to them as cestodes. The best-known species are commonly called tapeworms. All cestodes are parasitic and their life histories vary, but typically they live in the digestive tracts of vertebrates as adults, and often in the bodies of other species of animals as juveniles. Over a thousand species have been described, and all vertebrate species may be parasitised by at least one species of tapeworm.

Humans are subject to infection by several species of tapeworms if they eat undercooked meat such as pork (Taenia solium), beef (T. saginata), and fish (Diphyllobothrium spp.), or if they live in, or eat food prepared in, conditions of poor hygiene (Hymenolepis or Echinococcus species).

T. saginata, the beef tapeworm, can grow up to 20 m (65 ft); the largest species, the whale tapeworm Polygonoporus giganticus, can grow to over 30 m (100 ft). Species using small vertebrates as hosts, though, tend to be small. For example, vole and lemming tapeworms are only 13–240 mm (0.51–9.45 in) in length, and those parasitizing shrews only 0.8–60 mm (0.031–2.362 in).

Tapeworm (band)

Tapeworm is a defunct side project of Nine Inch Nails which existed in various forms from 1995 to roughly 2004. Tapeworm never released any recordings, but was frequently referenced in interviews. The band started as a side-project between Nine Inch Nails frontman Trent Reznor and live-band members Danny Lohner and Charlie Clouser. Through the years the group expanded and evolved numerous times to include artists such as Maynard James Keenan, Atticus Ross, and Alan Moulder, effectively turning the project into a supergroup. After many years of rumors and expected release dates, Reznor announced the end of the project in 2004.

History

Tapeworm's genesis occurred during Nine Inch Nails recording sessions following The Downward Spiral tours circa 1996. While working on Nine Inch Nails material, Danny Lohner and Charlie Clouser, both Nine Inch Nails live band members, would often come up with ideas that Reznor felt did not fit in with his vision for the band. Tapeworm developed as an outlet for this material—a democratic group in which Lohner and Clouser could act as equals with Reznor, as opposed to Nine Inch Nails, in which Reznor maintained sole artistic control.

Tapeworm (Stamford band)

Tapeworm (stylized as TAPEWOЯM) is an American hardcore punk band formed in 1978 in Stamford, Connecticut. The band was established by guitarist Tom Flynn and bassist Brian Beattie, whom established the band with fellow high school friends Jason Weinberg (drums) and Wayne Zito (guitar). Despite only being active for one year, their sole 7" release, "Break My Face" has gone on to be influential and a prized collector's item.

Biography

Tapeworm was formed in 1978 by Tom Flynn, Brian Beattie, Jason Weinberg, and Wayne Zito; all classmates at Rippowam High School. After practicing as a band, the name was chosen after they saw a bassist in a cover band with a Tapeworm sticker on his bass. Flynn, Beattie, and Weinberg were all previously in a jazz standard band in 1977. Tapeworm combined the diverse genres of each member; Flynn favored hard rock bands, such as Led Zeppelin and Aerosmith, Beattie and Weinberg preferred jazz, while Zito was a fan of metal. Zito wrote one of their first songs, "The Spider of the City", while they also added various Ramones songs to their setlist.

Blend modes

Blend modes (or Mixing modes) in digital image editing are used to determine how two layers are blended into each other. The default blend mode in most applications is simply to hide the lower layer with whatever is present in the top layer. However, as each pixel has a numerical representation, a large number of ways to blend two layers is possible. Note that the top layer is not necessarily called a "layer" in the application. It may be applied with a painting or editing tool.

Most graphics editing programs, like Adobe Photoshop and GIMP, allow the user to modify the basic blend modes - for example by applying different levels of opacity to the top picture.

Normal blend mode

This is the standard blend mode which uses the top layer alone, without mixing its colors with the layer beneath it.

Where a is the value of a color channel in the underlying layer, and b is that of the corresponding channel of the upper layer. The result is most typically merged into the bottom layer using "simple" (b over a) alpha compositing, but other Porter-Duff operations are possible. The compositing step results in the top layer's shape, as defined by its alpha channel, appearing over the bottom layer.
