Borehole Mining (BHM) is a remote operated method of extracting (mining) of mineral resources through boreholes by means of high pressure water jets. This process can be carried-out from land surface, open pit floor, underground mine or floating platform or vessel through pre-drilled boreholes. Borehole mining - The process. A borehole is drilled from land surface to a desired depth, where then an actual borehole mining will take a place. A casing column is lowered down the hole. Since BHM ta ...

Braiding of fiber yarn creates a strand or rope ...

In astronomy and navigation, the celestial sphere is an imaginary rotating sphere of "gigantic radius", concentric with the Earth. All objects in the sky can be thought of as lying upon the sphere. Projected, from their corresponding terrain equivalents, are the celestial equator and the celestial poles. Many ancient societies believed that the stars were equidistant from the Earth and that this sphere was a real model of the universe. This model is a useful abstraction, but not correct. Everything we see in the sky is so very ...

In geometry, coaxial means that two or more forms share a common axis; it is the three-dimensional analog of "concentric". Coaxial cable, for example, has a conducting wire in the center and a second conducting layer running all the way around the exterior circumference, under the insulation. The inner and outer conductors are separated by an insulating layer known as dielectric. Choice of materials and dimensions determines the cable's electrical properties, ...

Edward I of England - Crusades. In 1269 Cardinal Ottobono, the Papal Legate, arrived in England and appealed to Prince Edward and his brother Edmund to participate in the Eighth Crusade alongside Louis IX of France. In order to fund the crusade, Edward had to borrow heavily from Louis IX and the Jews of England. It is estimated by scholars such as P.R. Coss that Edward raised and spent close to half a million livres. The number of knights and retainers that accompanied Edward on the crusade was quite small, possi ...

A series (or string) consists of five shots fired at one target each within a limited time. The targets stand next to each other at a 25 m distance from the shooter. When the targets appear, the competitor must raise his arm from a 45 degree angle, and fire his five shots. If a shot is too late, it will score as a miss. There are three different time limits for the series: 8 seconds, 6 seconds, and 4 seconds. A stage consists of two series of each type, and a full course of fire comprises two such stages, or a total of 60 shots. Since the targets are divided into concentric score zones with 10 bei ...

Plane Dungeons & Dragons - Astral Plane. The Astral Plane is the plane of thought, memory, and psychic energy; it is where gods go when they die or are forgotten (or, most likely, both). It is a barren place with only rare bits of solid matter; some creatures, such as the tyrannous githyanki, use the petrified corpses of dead gods as floating fortresses. The Astral Plane is unique in that it is infinitesimal instead of infinite; there is no space or time here, though both catch up with you when you leave. The souls of the newly dead from the Prime Material Plan ...

Internal ballistics - Bore diameter and energy transfer. A firearm, in many ways, is like a piston engine on the power stroke. There is a certain amount of high-pressure gas available, and energy is extracted from it, by making the gas move a piston — in this case, the projectile is the piston. The swept volume of the piston determines how much energy can be extracted from the given gas. The more volume that is swept by the piston, the lower is the exhaust pressure (in this case, the ...

An Epitome of the Almagest (Epitome in Ptolemaei Almagestum) was written between 1460 and 1463 by the Austrian astronomer Georg Peurbach and his famous pupil Johannes Regiomontanus at the suggestion of Cardinal Bessarion. It gave Europeans the first sophisticated understanding of Ptolemy's astronomy, and was studied by every competent astronomer of the 16th century. Unlike earlier systems (such as 'the stars move because that is the will of the gods', or the model of concentric spheres), the Ptolemaic model explained all ...

The zone was established soon after the Chernobyl accident in 1986, in order to evacuate the local population and to prevent people from entering heavily contaminated territory. The area adjoining the site of the disaster was divided into 4 concentric zones, among them the fourth (actually the nearest, within a radius of 30 km) being the most dangerous. Any residence, civil or business activities there are legally prohibited and punishable. The only officially recognized exception is the functioning of the Chernobyl nuclear power plant and scientific installati ...
