Brukunga, South Australia
Brukunga is a small town in the Adelaide Hills, located approximately east of Adelaide and north of the town of Nairne. History Its name, derived from ''Barrukungga'' in the local Peramangk or Kaurna language, means "place of fire stone" or the "place of hidden fire", and is associated with the creator ancestor of the Kaurna people, Tjilbruke. Tjilbruke's body was said to have been transformed into the outcrop of iron pyrite at Barrukungga. However the etymology is complex and uncertain. While Brukunga is on Peramangk traditional land, the word Barrukungga has both Kaurna and Ngarrindjeri language elements. Norman Tindale noted that "The natives were well aware of the use of iron pyrites along with flint for the striking of fire and the area near Nairne was one of the places from which they obtained supplies of iron pyrites". Between 1955 and 31 May 1972, iron sulphides (mainly as pyrite) was mined at the Nairne Pyrite Mine—later renamed as the Brukunga Mine—immediatel ...

Port Adelaide
Port Adelaide is a port-side region of Adelaide, approximately northwest of the Adelaide city centre, 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 naming, dual name, is Yertabulti. History Prior to European settlement of South Australia, European settlement Port Adelaide was covered with Avicennia marina, 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 ar ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Aerial Firefighting
Aerial firefighting, also known as waterbombing, is the use of aircraft and other aerial resources to Wildfire suppression, combat wildfires. The types of aircraft used include fixed-wing aircraft and helicopters. Smokejumpers and rappellers are also classified as aerial firefighters, delivered to the fire by parachute from a variety of fixed-wing aircraft, or rappelling from helicopters. Chemicals used to fight fires may include water, water enhancers such as Fire-fighting foam, foams and Fire-retardant gel, gels, and specially formulated fire retardants such as Phos-Chek. Terminology The idea of fighting forest fires from the air dates back at least as far as Friedrich Karl von Koenig-Warthausen's observations on seeing a blaze when overflying the Santa Lucia Range, California, in 1929. A wide variety of terminology has been used in the popular media for the aircraft (and methods) used in aerial firefighting. The terms airtanker or air tanker generally refer to fixed-wing air ...

Country Fire Service
The South Australian Country Fire Service (SACFS, commonly abbreviated as CFS) is a volunteer based fire service in the Australian state of South Australia. The CFS has responsibility as the Control Agency for firefighting, rescues and Hazardous Wastes, hazardous materials and inland waterways in the country regions of South Australia. Its official mission is "To protect life, property and the environment from fire and other emergencies whilst protecting and supporting our personnel and continuously improving." Many parts of Australia are sparsely populated and under significant risk of Bushfires in Australia, bushfire. It would be prohibitively expensive for each Australian town or village to have a paid fire service (department). The compromise adopted is to have government funded equipment and training but volunteer fire-fighters to perform the duties of regular fire-fighters. In South Australia, the name for the volunteer service is the CFS. Each Australian State and Te ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Revegetation
Revegetation is the process of replanting and rebuilding the soil of disturbed land. This may be a natural process produced by plant colonization and succession, manmade rewilding projects, accelerated process designed to repair damage to a landscape due to wildfire, mining, flood, or other cause. Originally the process was simply one of applying seed and fertilizer to disturbed lands, usually grasses or clover. The fibrous root network of grasses is useful for short-term erosion control, particularly on sloping ground. Establishing long-term plant communities requires forethought as to appropriate species for the climate, size of stock required, and impact of replanted vegetation on local fauna. The motivations behind revegetation are diverse, answering needs that are both technical and aesthetic, but it is usually erosion prevention that is the primary reason. Revegetation helps prevent soil erosion, enhances the ability of the soil to absorb more water in significant rain ev ...

Cadmium
Cadmium is a chemical element; it has chemical symbol, symbol Cd and atomic number 48. This soft, silvery-white metal is chemically similar to the two other stable metals in group 12 element, group 12, zinc and mercury (element), mercury. Like zinc, it demonstrates oxidation state +2 in most of its compounds, and like mercury, it has a lower melting point than the transition metals in group 3 element, groups 3 through group 11 element, 11. Cadmium and its Congener (chemistry), congeners in group 12 are often not considered transition metals, in that they do not have partly filled ''d'' or ''f'' electron shells in the elemental or common oxidation states. The average concentration of cadmium in Earth's crust is between 0.1 and 0.5 parts per million (ppm). It was discovered in 1817 simultaneously by Friedrich Stromeyer, Stromeyer and Karl Samuel Leberecht Hermann, Hermann, both in Germany, as an impurity in zinc carbonate. Cadmium occurs as a minor component in most zinc ores and i ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Acid Mine Drainage
Acid mine drainage, acid and metalliferous drainage (AMD), or acid rock drainage (ARD) is the outflow of acidic water from metal mines and coal mines. Acid rock drainage occurs naturally within some environments as part of the rock weathering process but is exacerbated by large-scale earth disturbances characteristic of mining and other large construction activities, usually within rocks containing an abundance of sulfide minerals. Areas where the earth has been disturbed (e.g. construction sites or highway construction) may create acid rock drainage. In many localities, the liquid that drains from coal stocks, coal handling facilities, coal washeries, and coal waste tips can be highly acidic, and in such cases it is treated as acid rock drainage. These, combined with reduced pH, have a detrimental impact on the streams' aquatic environments. The same type of chemical reactions and processes may occur through the disturbance of acid sulfate soils formed under coastal or ...

Quarry
A quarry is a type of open-pit mining, open-pit mine in which dimension stone, rock (geology), rock, construction aggregate, riprap, sand, gravel, or slate is excavated from the ground. The operation of quarries is regulated in some jurisdictions to manage their safety risks and reduce their environmental impact. The word ''quarry'' can also include the underground quarrying for stone, such as Bath stone. History For thousands of years, only hand tools had been used in quarries. In the eighteenth century, the use of drilling and blasting operations was mastered. Types of rock Types of rock extracted from quarries include: *Chalk *China clay *Scoria, Cinder *Clay *Coal *Construction aggregate (sand and gravel) *Coquina *Diabase *Gabbro *Granite *Gritstone *Gypsum *Limestone *Marble *Ores *Phosphate rock *Quartz *Sandstone *Slate *Travertine Methods of quarrying The method of removal of stones from their natural bed by using different operations is called quarryin ...

Oxidation
Redox ( , , reduction–oxidation or oxidation–reduction) is a type of chemical reaction in which the oxidation states of the reactants change. Oxidation is the loss of electrons or an increase in the oxidation state, while reduction is the gain of electrons or a decrease in the oxidation state. The oxidation and reduction processes occur simultaneously in the chemical reaction. There are two classes of redox reactions: * Electron-transfer – Only one (usually) electron flows from the atom, ion, or molecule being oxidized to the atom, ion, or molecule that is reduced. This type of redox reaction is often discussed in terms of redox couples and electrode potentials. * Atom transfer – An atom transfers from one substrate to another. For example, in the rusting of iron, the oxidation state of iron atoms increases as the iron converts to an oxide, and simultaneously, the oxidation state of oxygen decreases as it accepts electrons released by the iron.
