Glaucus Mcfarlanei
In Greek mythology, Glaucus (; grc, Γλαῦκος, Glaûkos, glimmering) was a Greek prophetic sea-god, born mortal and turned immortal upon eating a magical herb. It was believed that he came to the rescue of sailors and fishermen in storms, having earlier earned a living from the sea himself. Family Glaucus's parentage is different in the different traditions: (i) Nereus; (ii) Copeus; (iii) Polybus, son of Hermes, and Euboea, daughter of Larymnus; (iv) Anthedon and Alcyone; or Poseidon and the nymph Naïs.Athenaeus, ''Deipnosophistae'7.294C pp. 328–33. Mythology Origin The story of Glaucus's apotheosis was dealt with in detail by Ovid in ''Metamorphoses'' and briefly referenced by many other authors. According to Ovid, Glaucus began his life as a mortal fisherman living in the Boeotian city of Anthedon. He found a magical herb which could bring the fish he caught back to life, and decided to try eating it. The herb made him immortal, but also caused him to grow f ...

Blue Button
The Blue Button is a system for patients to view online and download their own personal health records. Several Federal agencies, including the Departments of Defense, Health and Human Services, and Veterans Affairs, implemented this capability for their beneficiaries. In addition, Blue Button has pledges of support from numerous health plans and some vendors of personal health record vendors across the United States. Data from Blue Button-enabled sites can be used to create portable medical histories that facilitate dialog among health care providers, caregivers, and other trusted individuals or entities. , widespread Blue Button usage supported downloading human-readable data in ASCII. In January 2013, the Office of the National Coordinator for Health IT announced an implementation guide for data holders and developers to enable automated data exchange among Blue Button+ compliant applications using structured data formats. Blue Button+ is designed to enhance the ways consu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Portuguese Man O' War
The Portuguese man o' war (''Physalia physalis''), also known as the man-of-war, is a marine hydrozoan found in the Atlantic Ocean and the Indian Ocean. It is considered to be the same species as the Pacific man o' war or blue bottle, which is found mainly in the Pacific Ocean. The Portuguese man o' war is the only species in the genus ''Physalia'', which in turn is the only genus in the family Physaliidae. The Portuguese man o' war is a conspicuous member of the neuston, the community of organisms that live at the ocean surface. It has numerous venomous microscopic nematocysts which deliver a painful sting powerful enough to kill fish, and has been known to occasionally kill humans. Although it superficially resembles a jellyfish, the Portuguese man o' war is in fact a siphonophore. Like all siphonophores, it is a colonial organism, made up of many smaller units called zooids. All zooids in a colony are genetically identical, but fulfill specialized functions such as feeding ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cnidaria
Cnidaria () is a phylum under kingdom Animalia containing over 11,000 species of aquatic animals found both in freshwater and marine environments, predominantly the latter. Their distinguishing feature is cnidocytes, specialized cells that they use mainly for capturing prey. Their bodies consist of mesoglea, a non-living jelly-like substance, sandwiched between two layers of epithelium that are mostly one cell thick. Cnidarians mostly have two basic body forms: swimming medusae and sessile polyps, both of which are radially symmetrical with mouths surrounded by tentacles that bear cnidocytes. Both forms have a single orifice and body cavity that are used for digestion and respiration. Many cnidarian species produce colonies that are single organisms composed of medusa-like or polyp-like zooids, or both (hence they are trimorphic). Cnidarians' activities are coordinated by a decentralized nerve net and simple receptors. Several free-swimming species of Cubozoa and Scyphozo ...

Surface Tension
Surface tension is the tendency of liquid surfaces at rest to shrink into the minimum surface area possible. Surface tension is what allows objects with a higher density than water such as razor blades and insects (e.g. water striders) to float on a water surface without becoming even partly submerged. At liquid–air interfaces, surface tension results from the greater attraction of liquid molecules to each other (due to cohesion) than to the molecules in the air (due to adhesion). There are two primary mechanisms in play. One is an inward force on the surface molecules causing the liquid to contract. Second is a tangential force parallel to the surface of the liquid. This ''tangential'' force is generally referred to as the surface tension. The net effect is the liquid behaves as if its surface were covered with a stretched elastic membrane. But this analogy must not be taken too far as the tension in an elastic membrane is dependent on the amount of deformation of the m ...

Long Reef (New South Wales)
Long Reef is a prominent headland in the Northern Beaches of Sydney, Australia. Connected to the mainland by a tombolo, the reef has an extensive wave-cut platform. Long Reef is a popular recreational destination and is one of the more interesting geological areas in Sydney. Geology Some of the oldest rocks in the Sydney area may be seen at Long Reef. Primarily from the Triassic they are from the Narrabeen Group of sedimentary rocks. The cliffs of Long Reef are composed of Bald Hill Claystone above Bulgo Sandstone. There was a wide volcanic Dike (geology), dyke made of dolerite, two metres tall from the Jurassic. However, this has been reduced by mining. The most commonly seen type of rock in Sydney, Hawkesbury sandstone, is absent at Long Reef. It is present at Dee Why headland, a small distance to the south, separated by a Fault (geology), fault under Dee Why beach. A Copper extraction, copper mine was active at Long Reef in the 1880s,information sign at Long Reef – by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sydney North Shore
The North Shore is a region within Northern Sydney, in the state of New South Wales, Australia, generally referring to suburbs located on the northern side of Sydney Harbour up to Wahroonga, and suburbs between Middle Harbour and the Lane Cove River. The term "North Shore", used to describe this region of Sydney is customary, not legal or administrative, and is often subjective. History The region now referred to as the North Shore was home to a number a clans of the Eora. These included the Cammeraygal people whose traditional lands were located within what are now the Lower North Shore local government areas of North Sydney, Willoughby, Mosman, Manly and Warringah local government areas. The Cammeraygal people lived in the area until the 1820s and are recorded as being in the northern parts of the Sydney region for approximately 5,800 years. The Lower North Shore suburb of Cammeray takes its name from the clan, although the Cameragal clan was centred around, Kayyeemy, o ...

Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

Cerata
:''The tortrix moth genus ''Cerata'' is considered a junior synonym of ''Cydia. Cerata, singular ceras, are anatomical structures found externally in nudibranch sea slugs, especially in aeolid nudibranchs, marine opisthobranch gastropod mollusks in the clade Aeolidida. The word ceras comes from the Greek word "κέρας", meaning "horn", a reference to the shape of these structures. Cerata are dorsal and lateral outgrowths on the upper surfaces of the body of these nudibranchs. Function Cerata greatly extend the surface area of nudibranchs and aid in respiration, the process of gas exchange for metabolic use. Cerata are also used, in some cases, for attack and defense. In many aeolid nudibranchs, the digestive system extends into the cerata. These nudibranchs eat stinging celled animals (Cnidarians) such as anemones, hydroids and sea fans or Portuguese men o' war. The stinging cells or nematocysts are passed unharmed through the digestive system to cnidosacs at the tips of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australian Broadcasting Corporation
The Australian Broadcasting Corporation (ABC) is the national broadcaster of Australia. It is principally funded by direct grants from the Australian Government and is administered by a government-appointed board. The ABC is a publicly-owned body that is politically independent and fully accountable, with its charter enshrined in legislation, the ''Australian Broadcasting Corporation Act 1983''. ABC Commercial, a profit-making division of the corporation, also helps to generate funding for content provision. The ABC was established as the Australian Broadcasting Commission on 1 July 1932 by an act of federal parliament. It effectively replaced the Australian Broadcasting Company, a private company established in 1924 to provide programming for A-class radio stations. The ABC was given statutory powers that reinforced its independence from the government and enhanced its news-gathering role. Modelled after the British Broadcasting Corporation (BBC), which is funded by a tel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
