Banjawarn Station
Banjawarn Station is a remote cattle station in Western Australia, that previously operated as a sheep station. In the 1990s the lease to Banjawarn was owned by the Japanese doomsday cult Aum Shinrikyo, and following the Tokyo subway attack was the subject of an Australian Federal Police (AFP) investigation. Banjawarn is one of the 70 largest stations in Australia. Description It is situated 350 km (220 miles) north of Kalgoorlie and 800 km (500 miles) north east of Perth, on the edge of the Great Victoria Desert in the community of Leonora. It covers an area of . The land is a mix of Wanderrie, mulga, saltbush and grasslands that support both annual and perennial grasses. Gum trees and mulga follow the four main creeks and other watercourses. Several waterholes and lake systems are also found on the property. History The station was established in 1903 and has had several owners. In 1928, Banjawarn was owned by the Warren brothers and was supporting a flock of ...

Cattle Station
In Australia and New Zealand, a cattle station is a large farm ( station is equivalent to the American ranch), the main activity of which is the rearing of cattle. The owner of a cattle station is called a '' grazier''. The largest cattle station in the world is Anna Creek Station in South Australia, which covers an area of . Improvements Each station has a homestead where the property owner or the manager lives. Nearby cottages or staff quarters provide housing for the employees. Storage sheds and cattle yards are also sited near the homestead. Other structures depend on the size and location of the station. Isolated stations will have a mechanic's workshop, schoolroom, a small general store to supply essentials, and possibly an entertainment or bar area for the owners and staff. Water may be supplied from a river, bores or dams, in conjunction with rainwater tanks. Nowadays, if rural mains power is not connected, electricity is typically provided by a generator, although ...

Mahikari
The Mahikari movement (Japanese: ) is a Japanese new religious movement (''shinshūkyō'') that was founded in 1959 by Yoshikazu Okada (岡田 良一) (1901–1974). The word "Mahikari" means "True (真, ma) Light (光, hikari)" in Japanese. The movement currently consists of various splinter organizations; the largest ones are currently World Divine Light ( 世界真光文明教団) in Izu and Sukyo Mahikari ( 崇教真光) in Takayama. Both of these organizations refer to their headquarters as ("God's throne"), since they are the shrines for the supreme . Both organizations also refer to their spiritual leader as ''Oshienushi'' or ''Oshienushi-sama'' (教え主 ��. Foundation The original Mahikari organization was founded by Kōtama Okada (born Yoshikazu Okada) in 1959. The organization was originally named L. H. Yokoshi no Tomo (陽光子友乃会, ''Yokoshi Tomo no Kai'', "Lucky, Healthy, Association of Bright / Positive People"). Beliefs Kōtama Okada claimed that his ro ...

Asteroid
An asteroid is a minor planet—an object larger than a meteoroid that is neither a planet nor an identified comet—that orbits within the Solar System#Inner Solar System, inner Solar System or is co-orbital with Jupiter (Trojan asteroids). Asteroids are rocky, metallic, or icy bodies with no atmosphere, and are broadly classified into C-type asteroid, C-type (carbonaceous), M-type asteroid, M-type (metallic), or S-type asteroid, S-type (silicaceous). The size and shape of asteroids vary significantly, ranging from small rubble piles under a kilometer across to Ceres (dwarf planet), Ceres, a dwarf planet almost 1000 km in diameter. A body is classified as a comet, not an asteroid, if it shows a coma (tail) when warmed by solar radiation, although recent observations suggest a continuum between these types of bodies. Of the roughly one million known asteroids, the greatest number are located between the orbits of Mars and Jupiter, approximately 2 to 4 astronomical unit, AU ...

Air Burst
An air burst or airburst is the detonation of an explosive device such as an anti-personnel artillery shell or a nuclear weapon in the air instead of on contact with the ground or target. The principal military advantage of an air burst over a ground burst is that the energy from the explosion, including any shell fragments, is distributed more evenly over a wider area; however, the peak energy is lower at ground zero. History The shrapnel shell was invented by Henry Shrapnel of the British Army in about 1780 to increase the effectiveness of canister shot. It was used in the later Napoleonic wars and stayed in use until superseded in Artillery of World War I. Modern shells, though sometimes called "shrapnel shells", actually produce fragments and splinters, not shrapnel. Air bursts were used in the First World War to shower enemy positions and men with shrapnel balls to kill the largest possible number with a single burst. When infantry moved into deep trenches, ...

Bolide
A bolide is normally taken to mean an exceptionally bright meteor, but the term is subject to more than one definition, according to context. It may refer to any large Impact crater, crater-forming body, or to one that explodes in the atmosphere. It can be a synonym for a Meteoroid#Fireball, fireball, sometimes specific to those with an apparent magnitude of −4 or brighter. Definitions The word ''bolide'' (; from Italian language, Italian via Latin, ) may refer to somewhat different phenomena depending on the context in which the word appears, and readers may need to make inferences to determine which meaning is intended in a particular publication. An early usage occurs in ''Natural History (Pliny), Natural History'', where Pliny the Elder describes two types of prodigium, prodigies, "those which are called lampades and those which are called bolides". At least one of the prodigies described by Pliny (a "spark" that fell, grew to the "size of the moon", and "returned into the ...

Asteroid Impact
An impact event is a collision between astronomical objects causing measurable effects. Impact events have been found to regularly occur in planetary systems, though the most frequent involve asteroids, comets or meteoroids and have minimal effect. When large objects impact terrestrial planets such as the Earth, there can be significant physical and Biosphere, biospheric consequences, as the impacting body is usually traveling at several kilometres per second (km/s), with a minimum impact speed of 11.2 km/s (7.0 mi/s) for bodies striking Earth. Atmosphere, While planetary atmospheres can mitigate some of these impacts through the effects of atmospheric entry, many large bodies retain sufficient energy to reach the surface and cause substantial damage. This results in the formation of Impact crater, impact craters and Impact structure, structures, shaping the dominant landforms found across various types of solid objects found in the Solar System. Their prevalence and ubiquity pres ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seismic Activity
An earthquakealso called a quake, tremor, or tembloris the shaking of the Earth's surface resulting from a sudden release of energy in the lithosphere that creates seismic waves. Earthquakes can range in intensity, from those so weak they cannot be felt, to those violent enough to propel objects and people into the air, damage critical infrastructure, and wreak destruction across entire cities. The seismic activity of an area is the frequency, type, and size of earthquakes experienced over a particular time. The seismicity at a particular location in the Earth is the average rate of seismic energy release per unit volume. In its most general sense, the word ''earthquake'' is used to describe any seismic event that generates seismic waves. Earthquakes can occur naturally or be induced by human activities, such as mining, fracking, and nuclear weapons testing. The initial point of rupture is called the hypocenter or focus, while the ground level directly above it is the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dimethyl Methylphosphonate
Dimethyl methylphosphonate is an organophosphorus compound with the chemical formula CH3PO(OCH3)2. It is a colourless liquid, which is primarily used as a flame retardant. Synthesis Dimethyl methylphosphonate can be prepared from trimethyl phosphite and a halomethane (e.g. iodomethane) via the Michaelis–Arbuzov reaction. Dimethyl methylphosphonate is a schedule 2 chemical as it may be used in the production of chemical weapons. It will react with thionyl chloride to produce methylphosphonic acid dichloride, which is used in the production of sarin and soman nerve agents. Various amines can be used to catalyse this process. It can be used as a sarin-simulant for the calibration of organophosphorus detectors. Uses The primary commercial use of dimethyl methylphosphonate is as a flame retardant. Other commercial uses are a preignition additive for gasoline, anti-foaming agent, plasticizer, stabilizer, textile conditioner, antistatic agent, and an additive for solvents and low ...

Tokyo Subway Sarin Attack
The was a Chemical terrorism, chemical domestic terrorism, domestic terrorist attack perpetrated on 20 March 1995, in Tokyo, Japan, by members of the Aum Shinrikyo cult. In five coordinated attacks, the perpetrators released sarin on three lines of the Tokyo Metro (then ''Teito Rapid Transit Authority'') during rush hour, killing 13 people, severely injuring 50 (some of whom later died), and causing temporary vision problems for nearly 1,000 others. The attack was directed against trains passing through Kasumigaseki and Nagatachō, Tokyo, Nagatachō, where the National Diet (Japanese parliament) is headquartered in Tokyo. The group, led by Shoko Asahara, had already carried out several assassinations and terrorist attacks using sarin, including the Matsumoto sarin attack nine months earlier. They had also produced several other nerve agents, including VX (nerve agent), VX, attempted to produce botulinum toxin and had perpetrated several failed acts of bioterrorism. Asahara had b ...

Water Well
A well is an excavation or structure created on the earth by digging, driving, or drilling to access liquid resources, usually water. The oldest and most common kind of well is a water well, to access groundwater in underground aquifers. The well water is drawn up by a pump, or using containers, such as buckets that are raised mechanically or by hand. Water can also be injected back into the aquifer through the well. Wells were first constructed at least eight thousand years ago and historically vary in construction from a sediment of a dry watercourse to the qanats of Iran, and the stepwells and sakiehs of India. Placing a lining in the well shaft helps create stability, and linings of wood or wickerwork date back at least as far as the Iron Age. Wells have traditionally been sunk by hand digging, as is still the case in rural areas of the developing world. These wells are inexpensive and low-tech as they use mostly manual labour, and the structure can be lined with b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perchloric Acid
Perchloric acid is a mineral acid with the formula H Cl O4. It is an oxoacid of chlorine. Usually found as an aqueous solution, this colorless compound is a stronger acid than sulfuric acid, nitric acid and hydrochloric acid. It is a powerful oxidizer when hot, but aqueous solutions up to approximately 70% by weight at room temperature are generally safe, only showing strong acid features and no oxidizing properties. Perchloric acid is useful for preparing perchlorate salts, especially ammonium perchlorate, an important rocket fuel component. Perchloric acid is dangerously corrosive and readily forms potentially explosive mixtures. History Perchloric acid was first synthesized (together with potassium perchlorate) by Austrian chemist and called "oxygenated chloric acid" in mid-1810s. French pharmacist Georges-Simon Serullas introduced the modern designation along with discovering its solid monohydrate, which he mistook for an anhydride. Berzelius produced dilute perchloric acid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
