Mammal

Mammals (class Mammalia /məˈmeɪli.ə/ from Latin mamma "breast") are any members of a clade of endothermic amniotes distinguished from reptiles and birds by the possession of a neocortex (a region of the brain), hair, three middle ear bones, and mammary glands. The mammalian brain regulates body temperature and the circulatory system, including the four-chambered heart.

Mammals include the largest animals on the planet, the rorquals and other large whales, as well as some of the most intelligent, such as elephants, primates, including humans, and cetaceans. The basic body type is a four-legged land-borne animal, but some mammals are adapted for life at sea, in the air, in trees, or on two legs. The largest group of mammals, the placentals, have a placenta, which enables feeding the fetus during gestation. Mammals range in size from the 30–40 mm (1.2–1.6 in) bumblebee bat to the 33-meter (108 ft) blue whale.

The word "mammal" is modern, from the scientific name Mammalia coined by Carl Linnaeus in 1758, derived from the Latin mamma ("teat, pap"). All female mammals nurse their young with milk, which is secreted from special glands, the mammary glands. According to Mammal Species of the World, 5,416 species were known in 2006. These were grouped in 1,229 genera, 153 families and 29 orders. In 2008 the IUCN completed a five-year, 1,700-scientist Global Mammal Assessment for its IUCN Red List, which counted 5,488 accepted species.

Mammal (EP)

Mammal is the self-titled debut Extended play (EP), by Australian hard rock band, Mammal from 2006. The band sold the EP independently at their live shows and on their website until early 2007 when they signed with Metropolitan Groove Merchants (MGM) to distribute it independently. The original version (no longer in print) was replaced by the MGM version, released in March. The EP peaked into the top 20 of the AIR Charts.

Background

Mammal formed in Melbourne, Australia in March 2006 when vocalist Ezekiel Ox (ex-Full Scale Deflection, Full Scale) joined guitarist Pete Williamson (ex-Pete Murray & the Stonemasons) who was writing songs with session bass guitarist, Nick Adams; the trio were joined by drummer, Zane Rosanoski. In mid-2006 they entered the Sing Sing Studios to record their self-titled debut five-track Extended Play (EP), Mammal, which was sold independently at their live shows and on their website. By early 2007, they signed with Metropolitan Groove Merchants (MGM) which distributed their EP from March, which peaked into the top 20 of the AIR Charts.

Repulsion (film)

Repulsion is a 1965 British psychological horror film directed by Roman Polanski, and starring Catherine Deneuve, Ian Hendry, John Fraser and Yvonne Furneaux. The screenplay was based on a scenario by Gérard Brach and Polanski. The plot focuses on a young woman who is left alone by her vacationing sister at their apartment, and begins reliving traumas of her past in horrific ways. Shot in London, it was Polanski's first English-language film and second feature length production, following Knife in the Water (1962).

The film debuted at the 1965 Cannes Film Festival before receiving theatrical releases internationally. Upon its release, Repulsion received considerable critical acclaim and currently is considered one of Polanski's greatest movies. It was the first installment in Polanski's "Apartment Trilogy", followed by Rosemary's Baby (1968) and The Tenant (1976), both of which are also horror films that take place primarily inside apartment buildings. The film was nominated for a BAFTA Award for Gilbert Taylor's cinematography.

Cohesion (chemistry)

Cohesion (from Latin cohaerere "stick or stay together") or cohesive attraction or cohesive force is the action or property of like molecules sticking together, being mutually attractive. It is an intrinsic property of a substance that is caused by the shape and structure of its molecules, which makes the distribution of orbiting electrons irregular when molecules get close to one another, creating electrical attraction that can maintain a microscopic structure such as a water drop. In other words, cohesion allows for surface tension, creating a "solid-like" state upon which light (in weight) or low-density materials can be placed.

Water, for example, is strongly cohesive as each molecule may make four hydrogen bonds to other water molecules in a tetrahedral configuration. This results in a relatively strong Coulomb force between molecules. In simple terms, the polarity (state of which a molecule is oppositely charged on its poles) of water molecules allows them to be attracted towards each other. The polarity is due to the electronegativity of the atom of oxygen ; oxygen is more electronegative than the atoms of hydrogen, so the electrons they share through the covalent bonds are more often close to oxygen rather than hydrogen : these are called polar covalent bonds, covalent bonds between atoms that thus become oppositely charged. In the case of a water molecule, the hydrogen atoms carry positive charges while the oxygen atom has a negative charge. This charge polarization within the molecule allows it to align with adjacent molecules through strong intermolecular hydrogen bonding, rendering the bulk liquid cohesive. Van der Waals gases such as methane, however, have weak cohesion due only to Van der Waals forces that operate by induced polarity in non-polar molecules.
