2b2t.org (server) [6] 2b2t (2builders2tools) is a Minecraft server founded in December 2010. 2b2t has essentially no rules and players are not permanently banned, known within Minecraft as an " anarchy server". [2] As a result, players commonly engage in the destruction of other players' and groups creations, colloquially called "griefing", as ...
Mudstone. Mudstone, a type of mudrock, is a fine-grained sedimentary rock whose original constituents were clays or muds. Mudstone is distinguished from shale by its lack of fissility (parallel layering). [1][2] The term mudstone is also used to describe carbonate rocks (limestone or dolomite) that are composed predominantly of carbonate mud. [3]
Ground-penetrating radar (GPR) is a geophysical method that uses radar pulses to image the subsurface. It is a non-intrusive method of surveying the sub-surface to investigate underground utilities such as concrete, asphalt, metals, pipes, cables or masonry. [1] This nondestructive method uses electromagnetic radiation in the microwave band ...
Laser-induced breakdown spectroscopy (LIBS) is a type of atomic emission spectroscopy which uses a highly energetic laser pulse as the excitation source. [1][2] The laser is focused to form a plasma, which atomizes and excites samples. The formation of the plasma only begins when the focused laser achieves a certain threshold for optical ...
X-ray photoelectron spectroscopy is a chemical analysis technique relying on the photoelectric effect, usually employed in surface science. Radiation implosion is the use of high energy X-rays generated from a fission explosion (an A-bomb) to compress nuclear fuel to the point of fusion ignition (an H-bomb).
Orthovoltage X-rays are produced by X-ray tubes operating at voltages in the 100–500 kV range, and therefore the X-rays have a peak energy in the 100–500 keV range. [1] Orthovoltage X-rays are sometimes termed "deep" X-rays (DXR). [2] They cover the upper limit of energies used for diagnostic radiography, and are used in external beam ...
Grazing incidence diffraction geometry. The angle of incidence, α, is close to the critical angle for the sample. The beam is diffracted in the plane of the surface of the sample by the angle 2θ, and often also out of the plane. Grazing incidence diffraction (GID) is a technique for interrogating a material using small incidence angles for an ...
XYZ (French band) XYZ is a French-American hard rock band. It was originally formed in Lyon, France, where Pat Fontaine and Terry Ilous were born and grew up. The first members were Paul Villet on drums, Uncle RV on guitars and Pat Fontaine on vocals and bass. After a few shows as a trio through western Europe and even New York's CBGB, Terry ...
