Bolivar, South Australia
Bolivar is an outer northern suburb of Adelaide, South Australia. It is located in the City of Salisbury. History The suburb was established in 1956, and was named after the ''General Bolivar Hotel''. This hotel had been built by Walter Walpole, a settler who had arrived in South Australia in 1850 on the sailing ship ''Bolivar''. Bolivar Post Office in the then rural area opened on 1 July 1905 and closed in 1930. Geography Bolivar lies beside Barker Inlet and is bounded on the south by the Little Para River and on the east by Port Wakefield Road. Demographics The 2006 Census by the Australian Bureau of Statistics counted 119 persons in Bolivar on census night. Of these, 63.9% were male and 36.1% were female. The majority of residents (69.7%) are of Australian birth, with an additional 13.4% claiming England as their country of birth. The age distribution of Bolivar residents is skewed towards an older population compared to the greater Australian population: 94.1% of reside ...

Adelaide City Centre
Adelaide city centre (Kaurna: Tarndanya) is the inner city locality of Greater Adelaide, the capital city of South Australia. It is known by locals simply as "the City" or "Town" to distinguish it from Greater Adelaide and from the City of Adelaide local government area (which also includes North Adelaide and from the Park Lands around the whole city centre). The population was 15,115 in the . Adelaide city centre was planned in 1837 on a greenfield site following a grid layout, with streets running at right angles to each other. It covers an area of and is surrounded by of park lands.The area of the park lands quoted is based, in the absence of an official boundary between the City and North Adelaide, on an east–west line past the front entrance of Adelaide Oval. Within the city are five parks: Victoria Square in the exact centre and four other, smaller parks. Names for elements of the city centre are as follows: *The "city square mile" (in reality 1.67 square miles ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australian Bureau Of Statistics
The Australian Bureau of Statistics (ABS) is the independent statutory agency of the Australian Government responsible for statistical collection and analysis and for giving evidence-based advice to federal, state and territory governments. The ABS collects and analyses statistics on economic, population, environmental and social issues, publishing many on their website. The ABS also operates the national Census of Population and Housing that occurs every five years. History In 1901, statistics were collected by each state for their individual use. While attempts were made to coordinate collections through an annual Conference of Statisticians, it was quickly realized that a National Statistical Office would be required to develop nationally comparable statistics. The Commonwealth Bureau of Census and Statistics (CBCS) was established under the Census and Statistics Act in 1905. Sir George Knibbs was appointed as the first Commonwealth Statistician. Initially, the bureau w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boron
Boron is a chemical element with the symbol B and atomic number 5. In its crystalline form it is a brittle, dark, lustrous metalloid; in its amorphous form it is a brown powder. As the lightest element of the ''boron group'' it has three valence electrons for forming covalent bonds, resulting in many compounds such as boric acid, the mineral borax, sodium borate, and the ultra-hard crystals of boron carbide and boron nitride. Boron is synthesized entirely by cosmic ray spallation and supernovae and not by stellar nucleosynthesis, so it is a low-abundance element in the Solar System and in the Crust (geology), Earth's crust. It constitutes about 0.001 percent by weight of Earth's crust. It is concentrated on Earth by the water-solubility of its more common naturally occurring compounds, the borate minerals. These are mined industrially as evaporites, such as borax and kernite. The largest known deposits are in Turkey, the largest producer of boron minerals. Elemental b ...

Fluoride
Fluoride (). According to this source, is a possible pronunciation in British English. is an inorganic, monatomic anion of fluorine, with the chemical formula (also written ), whose salts are typically white or colorless. Fluoride salts typically have distinctive bitter tastes, and are odorless. Its salts and minerals are important chemical reagents and industrial chemicals, mainly used in the production of hydrogen fluoride for fluorocarbons. Fluoride is classified as a weak base since it only partially associates in solution, but concentrated fluoride is corrosive and can attack the skin. Fluoride is the simplest fluorine anion. In terms of charge and size, the fluoride ion resembles the hydroxide ion. Fluoride ions occur on Earth in several minerals, particularly fluorite, but are present only in trace quantities in bodies of water in nature. Nomenclature Fluorides include compounds that contain ionic fluoride and those in which fluoride does not dissociate. The nom ...

Phosphorus
Phosphorus is a chemical element with the symbol P and atomic number 15. Elemental phosphorus exists in two major forms, white phosphorus and red phosphorus, but because it is highly reactive, phosphorus is never found as a free element on Earth. It has a concentration in the Earth's crust of about one gram per kilogram (compare copper at about 0.06 grams). In minerals, phosphorus generally occurs as phosphate. Elemental phosphorus was first isolated as white phosphorus in 1669. White phosphorus emits a faint glow when exposed to oxygen – hence the name, taken from Greek mythology, meaning 'light-bearer' (Latin ), referring to the " Morning Star", the planet Venus. The term '' phosphorescence'', meaning glow after illumination, derives from this property of phosphorus, although the word has since been used for a different physical process that produces a glow. The glow of phosphorus is caused by oxidation of the white (but not red) phosphorus — a process now called chem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nitrogen
Nitrogen is the chemical element with the symbol N and atomic number 7. Nitrogen is a nonmetal and the lightest member of group 15 of the periodic table, often called the pnictogens. It is a common element in the universe, estimated at seventh in total abundance in the Milky Way and the Solar System. At standard temperature and pressure, two atoms of the element bond to form N2, a colorless and odorless diatomic gas. N2 forms about 78% of Earth's atmosphere, making it the most abundant uncombined element. Nitrogen occurs in all organisms, primarily in amino acids (and thus proteins), in the nucleic acids ( DNA and RNA) and in the energy transfer molecule adenosine triphosphate. The human body contains about 3% nitrogen by mass, the fourth most abundant element in the body after oxygen, carbon, and hydrogen. The nitrogen cycle describes the movement of the element from the air, into the biosphere and organic compounds, then back into the atmosphere. Many indus ...

Port River
The Port River (officially known as the Port Adelaide River) is part of a tidal estuary located north of the Adelaide city centre in the Australian state of South Australia. It has been used as a shipping channel since the beginning of European settlement of South Australia in 1836, when Colonel Light selected the site to use as a port. Before colonisation, the Port River region and the estuary area were known as Yerta Bulti (or Yertabulti) by the Kaurna people, and used extensively as a source of food and plant materials to fashion artefacts used in daily life. The Port River dolphins are a popular tourist attraction. Geography The Port River is the western branch of the largest tidal estuary on the eastern side of Gulf St Vincent. The whole estuarine area, sometimes called the Port River estuary, includes Barker Inlet, Torrens Island, Garden Island, and to a greater or lesser extent touches the suburbs of St Kilda, Bolivar, Dry Creek, Port Adelaide, New Port, and (up ...

Pollutant
A pollutant or novel entity is a substance or energy introduced into the environment that has undesired effects, or adversely affects the usefulness of a resource. These can be both naturally forming (i.e. minerals or extracted compounds like oil) or anthropogenic in origin (i.e. manufactured materials or byproducts from biodegradation). Pollutants result in environmental pollution or become public health concerns when they reach a concentration high enough to have significant negative impacts. A pollutant may cause long- or short-term damage by changing the growth rate of plant or animal species, or by interfering with human amenities, comfort, health, or property values. Some pollutants are biodegradable and therefore will not persist in the environment in the long term. However, the degradation products of some pollutants are themselves polluting such as the products DDE and DDD produced from the degradation of DDT. Pollution has widespread negative impacts on the enviro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Port Adelaide
Port Adelaide is a port-side region of Adelaide, approximately northwest of the Adelaide CBD. It is also the namesake of the City of Port Adelaide Enfield council, a suburb, a federal and state electoral division and is the main port for the city of Adelaide. Port Adelaide played an important role in the formative decades of Adelaide and South Australia, with the port being early Adelaide's main supply and information link to the rest of the world. Its Kaurna name, although not officially adopted as a dual name, is Yartapuulti. History Prior to European settlement Port Adelaide was covered with mangrove swamps and tidal mud flats, and lay next to a narrow creek. At this time, it was inhabited by the Kaurna people, who occupied the Adelaide Plains, the Barossa Valley, the western side of the Fleurieu Peninsula, and northwards past Snowtown. The Kaurna people called the Port Adelaide area Yartapuulti, and the whole estuarine area of the Port River ''Yertabulti'' (''Yerta B ...

Biosolids
Biosolids are solid organic matter recovered from a sewage treatment process and used as fertilizer. In the past, it was common for farmers to use animal manure to improve their soil fertility. In the 1920s, the farming community began also to use sewage sludge from local wastewater treatment plants. Scientific research over many years has confirmed that these biosolids contain similar nutrients to those in animal manures. Biosolids that are used as fertilizer in farming are usually treated to help to prevent disease-causing pathogens from spreading to the public. Some sewage sludge can not qualify as biosolids due to persistent, bioaccumulative and toxic chemicals, radionuclides, and heavy metals at levels sufficient to contaminate soil and water when applied to land. Terminology Biosolids may be defined as organic wastewater solids that can be reused after suitable sewage sludge treatment processes leading to sludge stabilization such as anaerobic digestion and composting. ...

Virginia, South Australia
Virginia is a town on the rural outskirts of Adelaide, the capital city of South Australia. Port Wakefield Road, the main highway taking traffic to the north of Adelaide, passes through the area and used to pass straight through Virginia. Market gardening is the main activity there. History Virginia was first surveyed and established by Daniel Brady (born 1797, died 1889), a wealthy Irish settler who had arrived in South Australia on the barque, DIADEM, in 1840 with his wife, Rose (née Rudden), and their six children. Daniel was one of the first settlers in the area with a land grant of 100 acres in Section 2186n, halfway between Dry Creek and the Little Para River in October 1848. He named the area Cavan after his home county in Ireland (cf. Virginia, County Cavan) and set aside section 176 and 3035 for the township of Virginia which he also named. Daniel Brady built the Wheatsheaf Hotel, the first prominent building erected at Virginia, in 1854. The hotel was there for ...
