A sudden large decrease in the shearing resistance of a cohesionless soil, caused by a collapse of the structure by shock or strain, and associated with a sudden but temporary increase of the pore fluid pressure.
Temporary transformation of a soil mass of soil or sediment into a fluid mass. Occurs when the cohesion of particles in the soil or sediment is lost. Often triggered by seismic waves from an earthquake. For this condition to take place the pore spaces between soil particles must be at or near saturation.
A process by which water-saturated materials (including soil, sediment, and certain types of volcanic deposits) lose strength and may fail during strong groundshaking. The transformation of granular material from a solid state into a liquefied state as a consequence of increased pore-water pressure.
A process by which formerly-firm soil can turn into quicksand. This often happens during an earthquake, when wet sand grains that are loosely bound together flow over one another, depriving anything (and anybody) standing on the surface of all support. Liquefaction was a major factor in the destruction of Port Royal in 1692.
The sudden large decrease of the shearing resistence of a cohesionless soil. It is caused by a collapse of structure by shock or other types of strain and is associated with a sudden, but temporary, increase of the porefluid pressure. It involves a temporary transformation of the material into a fluid-like mass.
The process in which a granular solid (soil) takes on the characteristics of a liquid as a result of an increase in pore pressure and a rgen_infotion in stress. In other words, solid ground looses cohesion and starts flowing like a liquid.
Process that takes clean natural gas and condenses it using a refrigeration process. Temperature of the gas is reduced to a very frigid - 260Â°F (-163Â°C), reducing its volume by more than 600 times. At this temperature LNG can be stored and transported as a liquid without having to be pressurized.
Shaking caused by an earthquake can cause the transformation of some loosely packed, water saturated sediments, such as sand and mud, into a fluid mass. The sediments thus lose their strength and can no longer support buildings which may then sink or lean.
A process by which water-saturated sediment temporarily loses strength and acts as a fluid, like when you wiggle your toes in the wet sand near the water at the beach. This effect can be caused by earthquake shaking.
the transformation of saturated, loosely packed, course-grained soils from a solid to a liquid state. The soil grains temporarily lose contact with each other and the particle weight is transferred to the pore water. CO Survey, 1988.
The first major step in the conversion of starch to syrup. The starch as a raw material comes as dry matter and needs to be first gelatinized and liquefied to make it susceptible to further enzymatic breakdown. This is achieved by adding a temperature-stable enzyme to the starch suspension. The mechanical part of the process involves the use of stirred tank reactors, continuous stirred tank reactors or jet cookers.
The acid- or enzyme-catalysed conversion of starch into a maltodextrin as either  intermediate material for further hydrolysis e.g. to glucose syrup or  as commercial product. The term thinning should not be used as a synonym in this context as it refers only to the initial viscosity reduction.
As alpha amylase breaks up the branched amylopectin molecules in the mash, the mash becomes less viscous and more fluid; hence the term liquefaction of the mash and alpha amylase being referred to as the liquefying enzyme.
