Australian Central Standard Time
Australia uses three main time zones: Australian Eastern Standard Time (AEST; UTC+10:00), Australian Central Standard Time (ACST; UTC+09:30) and Australian Western Standard Time (AWST; UTC+08:00). Time is regulated by the individual states and territories of Australia, state governments, some of which observe daylight saving time (DST). Daylight saving time (+1 hour) is used between the first Sunday in October and the first Sunday in April in jurisdictions in the south and south-east: * New South Wales, Victoria, Australia, Victoria, Tasmania, Jervis Bay Territory and the Australian Capital Territory switches to the Australian Eastern Daylight Saving Time (AEDT; UTC+11:00), and * South Australia switches to the Australian Central Daylight Saving Time (ACDT; UTC+10:30). Standard time was introduced in the 1890s when all of the Australian colonies adopted it. Before the switch to standard time zones, each local city or town was free to determine its local time, called local mea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lead Smelting
Plants for the production of lead are generally referred to as lead smelters. Primary lead production begins with sintering. Concentrated lead ore is fed into a sintering machine with iron, silica, limestone fluxes, coke, soda ash, pyrite, zinc, caustics or pollution control particulates. Smelting uses suitable reducing substances that will combine with those oxidizing elements to free the metal. Reduction is the final, high-temperature step in smelting. It is here that the oxide becomes the elemental metal. A reducing environment (often provided by carbon monoxide in an air-starved furnace) pulls the final oxygen atoms from the raw metal. Lead is usually smelted in a blast furnace, using the lead sinter produced in the sintering process and coke to provide the heat source. As melting occurs, several layers form in the furnace. A combination of molten lead and slag sinks to the bottom of the furnace, with a layer of the lightest elements referred to as speiss, including arse ...

Ben Germein
Benjamin "Ben" Germein (c. 1826 – c. July 1893) was a seaman and lighthouse-keeper in South Australia who is remembered as a hero of the wreck of the steamship Admella. History Ben arrived in South Australia on 22 April 1837 with his two brothers John and Samuel, John's wife Olinda (née Gover), his sister Thirza Elizabeth and her husband William Doddridge aboard the ''South Australian'' from Portsmouth. Their father John Germein sen. (c. 1786 – 23 April 1869) arrived in the ''Java'' in 1840. As soon as the Port was settled, Captain Quin was appointed pilot and the Germein brothers were his crew, all of whom were afterwards made pilots. Ben proved a remarkably clever pilot and was known for his ability to manoeuvre vessels under canvas. He was the first person to sail a ship under full sail the length of the Port River. He commanded the s.s. ''Corio'' between Port Elliot and Goolwa for River Murray Steam Navigation Company multiple times during 1857 until she foun ...

John Ainsworth Horrocks
John Ainsworth Horrocks (22 March 1818 – 23 September 1846) was an English pastoralist and explorer who was one of the first European settlers in the Clare Valley of South Australia where, in 1840, he established the village of Penwortham. Biography Horrocks was born on Easter Sunday, 22 March 1818, at Penwortham Lodge, near Preston, Lancashire. His father Peter Horrocks, a son of John Horrocks, was an investor/shareholder in the Secondary Towns Association, which aspired to develop towns in the new colony of South Australia. John Ainsworth Horrocks, aged 21, and his brother Eustace, aged 16, arrived at Adelaide in March 1839. Impatient to settle on their own land, the brothers set up camp on 16 January 1840 at present Penwortham, a village which they founded and named. He returned to England in 1842 after his father's death, and then went back to Australia in 1844 to attend to financial problems.

Matthew Flinders
Captain (Royal Navy), Captain Matthew Flinders (16 March 1774 – 19 July 1814) was a British Royal Navy officer, navigator and cartographer who led the first littoral zone, inshore circumnavigate, circumnavigation of mainland Australia, then called New Holland (Australia), New Holland. He is also credited as being the first person to utilise the name ''Australia'' to describe the entirety of that continent including Van Diemen's Land (now Tasmania), a title he regarded as being "more agreeable to the ear" than previous names such as ''Terra Australis''. Flinders was involved in several voyages of discovery between 1791 and 1803, the most famous of which are the circumnavigation of Australia and an earlier expedition when he and George Bass confirmed that Van Diemen's Land was an island. While returning to Britain in 1803, Flinders was arrested by the French at the colony of Isle de France (Mauritius), Isle de France. Although Britain and France were at war, Flinders thought t ...

Blood Lead Level
Blood lead level (BLL), is a measure of the amount of lead in the blood. Lead is a toxic heavy metal and can cause neurological damage, especially among children, at any detectable level. High lead levels cause decreased vitamin D and haemoglobin synthesis as well as anemia, acute central nervous system disorders, and possibly death. Pre-industrial human BLL measurements are estimated to have been 0.016 μg/dL, and this level increased markedly in the aftermath of the industrial revolution. At the end of the late 20th century, BLL measurements from remote human populations ranged from 0.8 to 3.2 μg/dL. Children in populations adjacent to industrial centers in developing countries often have average BLL measurements above 25 μg/dL. In the United States, the average blood level for children aged 1–5 years fell from 15.2 μg/dL in 1976–1980 to 0.83 μg/dL in 2011–2016, a change largely attributed to phasing out leaded gasoline. No level of le ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gold
Gold is a chemical element; it has chemical symbol Au (from Latin ) and atomic number 79. In its pure form, it is a brightness, bright, slightly orange-yellow, dense, soft, malleable, and ductile metal. Chemically, gold is a transition metal, a group 11 element, and one of the noble metals. It is one of the least reactivity (chemistry), reactive chemical elements, being the second-lowest in the reactivity series. It is solid under standard temperature and pressure, standard conditions. Gold often occurs in free elemental (native state (metallurgy), native state), as gold nugget, nuggets or grains, in rock (geology), rocks, vein (geology), veins, and alluvial deposits. It occurs in a solid solution series with the native element silver (as in electrum), naturally alloyed with other metals like copper and palladium, and mineral inclusions such as within pyrite. Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides). Gold is resistant to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acid
An acid is a molecule or ion capable of either donating a proton (i.e. Hydron, hydrogen cation, H+), known as a Brønsted–Lowry acid–base theory, Brønsted–Lowry acid, or forming a covalent bond with an electron pair, known as a Lewis acid. The first category of acids are the proton donors, or Brønsted–Lowry acid–base theory, Brønsted–Lowry acids. In the special case of aqueous solutions, proton donors form the hydronium ion H3O+ and are known as Acid–base reaction#Arrhenius theory, Arrhenius acids. Johannes Nicolaus Brønsted, Brønsted and Martin Lowry, Lowry generalized the Arrhenius theory to include non-aqueous solvents. A Brønsted–Lowry or Arrhenius acid usually contains a hydrogen atom bonded to a chemical structure that is still energetically favorable after loss of H+. Aqueous Arrhenius acids have characteristic properties that provide a practical description of an acid. Acids form aqueous solutions with a sour taste, can turn blue litmus red, and ...
