Sarcocapnos (Greek "sárx" "flesh", "kapnós" "smoke") is a genus of at least 6 species of somewhat fleshy, cushion-forming annual to perennial plants, native to cliffs in the French Pyrenees, Spain, and north Africa.
Language convergence is a type of linguistic change in which languages come to structurally resemble one another as a result of prolonged language contact and mutual interference.
 In contrast to other contact-induced language changes like creolization or the formation of mixed languages, convergence refers to a mutual process that results in changes in all the languages involved.
 Linguists use the term to describe changes in the linguistic patterns of the languages in contact rather than alterations of isolated lexical items.
The "Le Normand" class (or E52 Type) was a class of 14 fast frigates ("Escorteurs Rapide") built for the French Navy in the late 1950s.
 They were an immediate follow-on from the earlier "Le Corse"-class (or E50 Type) frigates, and like them, were long-range convoy escorts capable of high speed.
 The first seven ships, paid for by the United States under the Mutual Defense Assistance Act were ordered in 1952.
 The remaining seven ships were paid for by France and ordered between 1953 and 1955.
Under the "International Code of Zoological Nomenclature" ("Code"), the name-bearing type is the biological type that determines the application of a name.
 Each taxon regulated by the "Code" at least potentially has a name-bearing type.
 The name-bearing type can be either a type genus (family group), type species (genus group), or one or more type specimens (species group).
 For example, the name "Mabuya maculata" (Gray, 1839) has often been used for the Noronha skink (currently "Trachylepis atlantica"), but because the name-bearing type of the former, a lizard preserved in the Muséum national d'histoire naturelle in Paris, does not represent the same species as the Noronha skink, the name "maculata" cannot be used for the latter.
Derwentia was a genus of flowering plants that is endemic to Australia.
A 130–30 fund or a ratio up to 150/50 is a type of collective investment vehicle, often a type of specialty mutual fund, but which allows the fund manager simultaneously to hold both long and short positions on different equities in the fund.
 Traditionally, mutual funds were long-only investments.
 130–30 funds are a fast-growing segment of the financial industry; they should be available both as traditional mutual funds, and as exchange-traded funds (ETFs).
 While this type of investment has existed for a while in the hedge fund industry, its availability for retail investors is relatively new.
Derwentia is an extinct genus of trematosaurian temnospondyl within the family Rhytidosteidae.
 It is known from a single skull found from the Knocklofty Sandstone of Tasmania, which is Early Triassic in age.
Veronica nivea, the milfoil speedwell or snow speedwell, is a flowering plant species of the family Plantaginaceae, endemic to south-eastern Australia.
 It is sometimes included in the genus "Parahebe" or "Derwentia".
Veronica derwentiana (Derwent speedwell ) is a flowering plant species of the family Plantaginaceae, endemic to south-eastern Australia.
 It is sometimes included in the genus "Parahebe" or "Derwentia".
 It is a woody herb which grows to 140 cm high.
 Leaves are 5 to 20 cm long, with a cuneate, truncate or cordate base and toothed margins.
 The flowers are white, pale lilac or pale blue and appear in 5 to 20 cm long racemes of 40 to 100 flowers in summer.
 The species occurs in a variety of habitats including eucalypt forest and alpine herbfields in Queensland, New South Wales, Victoria, Tasmania and South Australia.
 It is often seen on disturbed sites.
A mutual-benefit nonprofit corporation or membership corporation is a type of nonprofit corporation in the US, similar to other mutual benefit organizations found in some of common law nations, chartered by government with a mandate to serve the mutual benefit of its members.
