The platypus (Ornithorhynchus anatinus), sometimes referred to as the duck-billed platypus, is a semiaquatic, egg-laying mammal endemic to eastern Australia, including Tasmania. The platypus is the sole living representative of its family (Ornithorhynchidae) and genus (Ornithorhynchus), though a number of related species appear in the fossil record.
Together with the four species of echidna, it is one of the five extant species of monotremes, the only mammals that lay eggs instead of giving birth to live young. Like other monotremes, it senses prey through electrolocation. It is one of the few species of venomous mammals, as the male platypus has a spur on the hind foot that delivers a venom, capable of causing severe pain to humans. The unusual appearance of this egg-laying, duck-billed, beaver-tailed, otter-footed mammal baffled European naturalists when they first encountered it, and the first scientists to examine a preserved platypus body (in 1799) judged it a fake, made of several animals sewn together.
The unique features of the platypus make it an important subject in the study of evolutionary biology, and a recognisable and iconic symbol of Australia. It is culturally significant to several Aboriginal peoples of Australia, who also used to hunt the animal for food. It has appeared as a mascot at national events and features on the reverse of the Australian twenty-cent coin, and the platypus is the animal emblem of the state of New South Wales. Until the early 20th century, humans hunted the platypus for its fur, but it is now protected throughout its range. Although captive-breeding programs have had only limited success, and the platypus is vulnerable to the effects of pollution, it is not under any immediate threat.
As of 2020, the platypus is a legally protected species in all states where it occurs. It is listed as an endangered species in South Australia and Victoria and has been recommended for listing in New South Wales. The species is classified as a near-threatened species by the IUCN, but a November 2020 report has recommended that it is upgraded to threatened species under the federal EPBC Act, due to habitat destruction and declining numbers in all states.Security is freedom from, or resilience against, potential harm (or other unwanted coercive change) caused by others. Beneficiaries (technically referents) of security may be of persons and social groups, objects and institutions, ecosystems or any other entity or phenomenon vulnerable to unwanted change.
Security mostly refers to protection from hostile forces, but it has a wide range of other senses: for example, as the absence of harm (e.g. freedom from want); as the presence of an essential good (e.g. food security); as resilience against potential damage or harm (e.g. secure foundations); as secrecy (e.g. a secure telephone line); as containment (e.g. a secure room or cell); and as a state of mind (e.g. emotional security).
The term is also used to refer to acts and systems whose purpose may be to provide security (e.g.: security companies, security forces, security guard, cyber security systems, security cameras, remote guarding).
Security is not only physical but it can also be virtual.
Hazzard was a German-British heavy metal band formed by Herman Frank of Accept fame. The band featured Malcolm McNulty on vocals, who later joined Sweet as both bass player and vocalist and then Slade as Mal McNulty. Hazzard's only album release was mixed by Michael Wagener at Dierks Studios, Cologne. Herman Frank has also played in Victory and Sinner. He has worked as a record producer for Saxon and Rose Tattoo.A county is a geographical region of a country used for administrative or other purposes in certain modern nations. The term is derived from the Old French conté or cunté denoting a jurisdiction under the sovereignty of a count (earl) or a viscount. Literal equivalents in other languages, derived from the equivalent of "count", are now seldom used officially, including comté, contea, contado, comtat, condado, Grafschaft, graafschap, and zhupa in Slavic languages; terms equivalent to English language administrative terms such as municipality, district, circuit and commune/community are now often instead used.
When the Normans conquered England, they brought the term with them. The Saxons had already established the districts that became the historic counties of England, calling them shires; many county names derive from the name of the county town (county seat) with the word shire added on: for example, Gloucestershire and Worcestershire. The Anglo-Saxon terms earl and earldom were taken as equivalent to the continental terms "count" and "county" under the conquering Normans, and over time the two blended and became equivalent. Further, the later-imported term became a synonym for the native Old English word sċīr ([ʃiːr]) or, in Modern English, shire – an equivalent administrative division of the kingdom. The term "county" evolved, consequently, to designate a level of local administration that was immediately beneath a national government, within a unitary (non-federal) system of government. County later also became used differently in some federal systems of government, for a local administrative division subordinate to a primary subnational entity, such as a Province (e.g. Canada) or a State (e.g. the United States); in these countries, a county is a level 3 territorial unit (NUTS 3).
In the United States and Canada, founded 600 years later on the British traditions, counties are usually an administrative division set by convenient geographical demarcations, which in governance have certain officeholders (for example sheriffs and their departments) as a part of the state and provincial mechanisms, including geographically common court systems.A county may be further subdivided into districts, hundreds, townships or other administrative jurisdictions within the county. A county usually, but not always, contains cities, towns, townships, villages, or other municipal corporations, which in most cases are somewhat subordinate or dependent upon county governments. Depending on the nation, municipality, and local geography, municipalities may or may not be subject to direct or indirect county control — the functions of both levels are often consolidated into a city government when the area is densely populated.Outside English-speaking countries, an equivalent of the term county is often used to describe subnational jurisdictions that are structurally equivalent to counties in the relationship they have with their national government; but which may not be administratively equivalent to counties in predominantly English-speaking countries.
