green river missile launching site. the utah launch complex was a cold war military subinstallation of white sands missile range for usaf and us army rocket launches. in addition to firing pershing missiles, the complex launched athena rtv missiles with subscale test warheads of the advanced ballistic re-entry system to reentry speeds and .
hypochromic anemia is a generic term for any type of anemia in which the red blood cells are paler than normal. hypo- refers to less, and chromic means chrome. a normal red blood cell has a biconcave disk shape and will have an area of pallor in its center when viewed microscopically.
the 2018 australian ball-tampering scandal, also known as the sandpapergate scandal, was a cricket scandal surrounding the australian national cricket team.in march 2018, during the third test match against south africa at newlands in cape town, cameron bancroft was caught by television cameras trying to rough up one side of the ball with sandpaper to make it swing in flight.
shear strength is a term used in soil mechanics to describe the magnitude of the shear stress that a soil can sustain. the shear resistance of soil is a result of friction and interlocking of particles, and possibly cementation or bonding at particle contacts.
moisture analysis covers a variety of methods for measuring moisture content in both high level and trace amounts in solids, liquids, or gases. moisture in percentage amounts is monitored as a specification in commercial food production. there are many applications where trace moisture measurements are necessary for manufacturing and process quality assurance.
white sands test facility wstf is a u.s. government rocket engine test facility and a resource for testing and evaluating potentially hazardous materials, space flight components, and rocket propulsion systems. nasa established wstf on the white sands missile range in 1963. wstf services are available to nasa, the united states department of defense, other federal agencies, universities and .
dye penetrant inspection dp , also called liquid penetrate inspection lpi or penetrant testing pt , is a widely applied and low-cost inspection method used to check surface-breaking defects in all non-porous materials metals, plastics, or ceramics . the penetrant may be applied to all non-ferrous materials and ferrous materials, although for ferrous components magnetic-particle inspection .
fluorescent penetrant inspection fpi is a type of dye penetrant inspection in which a fluorescent dye is applied to the surface of a non-porous material in order to detect defects that may compromise the integrity or quality of the part in question. fpi is noted for its low cost and simple process, and is used widely in a variety of industries.
trinitite, also known as atomsite or alamogordo glass, is the glassy residue left on the desert floor after the plutonium-based trinity nuclear bomb test on july 16, 1945, near alamogordo, new mexico.the glass is primarily composed of arkosic sand composed of quartz grains and feldspar both microcline and smaller amount of plagioclase with small amount of calcite, hornblende and augite in a .
permeability in fluid mechanics and the earth sciences commonly symbolized as k is a measure of the ability of a porous material often, a rock or an unconsolidated material to allow fluids to pass through it.. the permeability of a medium is related to the porosity, but also to the shapes of the pores in the medium and their level of connectedness.
for critical applications, or where the cost of wasted effort is a factor, non-destructive testing methods may be applied before further work is performed. processes. in general, we can distinguish between two methods of sand casting; the first one using green sand and the second being the air set method. green sand
the compressive strength of the material would correspond to the stress at the red point shown on the curve. in a compression test, there is a linear region where the material follows hooke's law.hence, for this region, =, where, this time, e refers to the young's modulus for compression.in this region, the material deforms elastically and returns to its original length when the stress is removed.
