Keel (bird anatomy)

A keel or carina (plural carinae) in bird anatomy is an extension of the sternum (breastbone) which runs axially along the midline of the sternum and extends outward, perpendicular to the plane of the ribs. The keel provides an anchor to which a bird's wing muscles attach, thereby providing adequate leverage for flight. Keels do not exist on all birds; in particular, some flightless birds lack a keel structure.

Historically, the presence or absence of a pronounced keel structure was used as a broad classification of birds into two orders: Carinatae (from carina, "keel"), having a pronounced keel; and ratites (from ratis, "raft" — referring to the flatness of the sternum), having a subtle keel structure or lacking one entirely. However, this classification has fallen into disuse as evolutionary studies have shown that many flightless birds have evolved from flighted birds. The current definition of Carinatae now includes all extant birds.

Keel (band)

Keel is an American heavy metal band founded in 1984 in Los Angeles, California. They are known for their rock anthem "The Right to Rock." The band was active until 1989, with a brief reunion in 1998. Keel reunited again in 2008 and toured in 2009 for their 25th anniversary.

History

Keel was formed by former Steeler vocalist Ron Keel. The original members were Ron Keel on vocals, David Michael Phillips on guitar, Marc Ferrari on lead & rhythm guitars, Bobby Marks on drums and Kenny Chaisson on bass guitar. Within months, Phillips left to join King Kobra and was replaced by Brian Jay. This was the lineup for their 1984 debut album Lay Down the Law. After the album's release, Marks left and was replaced by Steven Riley, who subsequently left early in the recording of the band's second album to join W.A.S.P., and was in turn replaced by Dwain Miller, forming a lineup which would remain stable for almost 4 years. Their debut album caught the eye of KISS' Gene Simmons, resulting in his production of their second album, The Right To Rock, released on March 26, 1985. Their next and also Simmons-produced third album The Final Frontier was released on April 30, 1986. It included the single "Because the Night", a song that was co-written by Patti Smith and Bruce Springsteen and had been a hit for Smith in 1978.

Labellum (botany)

In botany, the labellum (or lip) is the part of the flower of an orchid or Canna, or other less-known genera that serves to attract insects, which pollinate the flower, and acts as a landing platform for them.

Labellum (plural: labella) is the Latin diminutive of labium, meaning lip.

The labellum is a modified petal and can be distinguished from the other petals and from the sepals by its large size and its often irregular shape. It is not unusual for the other two petals of an orchid flower to look like the sepals, so that the labellum stands out as distinct.

In orchids, the labellum is the modified median petal that sits opposite from the fertile anther and usually highly modified from the other perianth segments. It is often united with the column and can be hinged or movable, facilitating pollination. Often, the orchid labellum is divided into three or more lobes. Some have modified fleshy lumps on the upper surface generally referred to as the callus, with some being divided into multiple ridges or a central keel. When the callus is flat and broad, it is sometimes called a plate, which can have fringed margins. The callus can be highly modified with striking colors that may aid in pollinator deceit and mimicry.

Slug

Slug, or land slug, is a common name for any apparently shell-less terrestrial gastropod mollusc. The word slug is also often used as part of the common name of any gastropod mollusc that has no shell, a very reduced shell, or only a small internal shell, particularly sea slugs and semislugs (this is in contrast to the common name snail, which applies to gastropods that have a coiled shell large enough that the animal can fully retract its soft parts into the shell).

Various taxonomic families of land slugs form part of several quite different evolutionary lineages, which also include snails. Thus, the various families of slugs are not closely related, despite a superficial similarity in the overall body form. The shell-less condition has arisen many times independently during the evolutionary past, and thus the category "slug" is emphatically a polyphyletic one.

Taxonomy

Of the six orders of Pulmonata, two – the Onchidiacea and Soleolifera – solely comprise slugs. A third family, the Sigmurethra, contains various clades of snails, semi-slugs (i.e. snails whose shells are too small for them to retract fully into) and slugs. The taxonomy of this group is in the process of being revised in light of DNA sequencing. It appears that pulmonates are paraphyletic and basal to the opisthobranchs, which are a terminal branch of the tree. The family Ellobiidae are also polyphyletic.

Bird

Birds (class Aves) are a group of endothermic vertebrates, characterised by feathers, a beak with no teeth, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a lightweight but strong skeleton. Birds live worldwide and range in size from the 5 cm (2 in) bee hummingbird to the 2.75 m (9 ft) ostrich. They rank as the class of tetrapods with the most living species, at approximately ten thousand, with more than half of these being passerines, sometimes known as perching birds or, less accurately, as songbirds.

The fossil record indicates that birds are the last surviving dinosaurs, having evolved from feathered ancestors within the theropod group of saurischian dinosaurs. True birds first appeared during the Cretaceous period, around 100 million years ago, and the last common ancestor is estimated to have lived about 95 million years ago. DNA-based evidence finds that birds radiated extensively around the time of the Cretaceous–Paleogene extinction event that killed off the non-avian dinosaurs. Birds in South America survived this event and then migrated to other parts of the world via multiple land bridges while diversifying during periods of global cooling. Primitive bird-like "stem-birds" that lie outside class Aves proper, in the group Avialae, have been found dating back to the mid-Jurassic period. Many of these early stem-birds, such as Archaeopteryx, were not yet capable of fully powered flight, and many retained primitive characteristics like toothy jaws in place of beaks and long bony tails.

The finger

In Western culture, the finger or the middle finger (as in giving someone the (middle) finger or the bird or flipping someone off,) is an obscene hand gesture. It communicates moderate to extreme contempt, and is roughly equivalent in meaning to "fuck off", "fuck you", "shove it up your ass", "up yours" or "go fuck yourself". It is performed by showing the back of a closed fist that has only the middle finger extended upwards, though in some locales the thumb is extended. Extending the finger is considered a symbol of contempt in several cultures, especially Western ones. Many cultures use similar gestures to display their disrespect, although others use it to express pointing without intentional disrespect toward other cultures.

The gesture dates back to Ancient Greece and it was also used in Ancient Rome. Historically, it represented the phallus. In some modern cultures, it has gained increasing recognition as a sign of disrespect, and has been used by music artists (notably more common among hardcore punk bands and rappers), actors, celebrities, athletes, and politicians. Most still view the gesture as obscene. The index finger and ring finger besides the middle finger in more contemporary periods has been likened to represent the testicles.

Birds (Marius Neset album)

Birds (released March 25, 2013 in Oslo, Norway by the label Edition Records – EDN1040) is the 4'th album of the Norwegian saxophonist Marius Neset.

Critical reception

The review by Neil Spencer of the British newspaper The Guardian awarded the album 5 stars, the review by Terje Mosnes of the Norwegian newspaper Dagbladet awarded the album dice 6, the review by Carl Petter Opsahk of the Norwegian newspaper Verdens Gang awarded the album dice 5, and the reviewer Ian Mann of the Jazz Mann awarded the album 4.5 stars

According to Mosnes, with this album, Neset takes further steps on his way to the Jazz sky. The brilliant compositions and the musical skills of this band are extraordinary. It is only to look forward to the next move of this great jazz musician and composer.
