This form of cerebellar degeneration may precede cancer. Alcoholic or nutritional cerebellar degeneration affects alcoholics and people with thiamine deficiency. It is not related to cancer and is more common than the paraneoplastic type.
Liquefaction is the process of loose soil acting like a liquid during an earthquake. Most of the time, buildings and homes are built upon solid bedrock.
EARTHQUAKE LIQUEFACTION. Earthquake liquefaction, often referred to simply as liquefaction, is the process by which saturated, unconsolidated soil or sand is converted into a suspension during an earthquake. The effect on structures and buildings can be devastating, and is a major contributor to urban seismic risk. Soil liquefaction, also called earthquake liquefaction, ground failure or loss of strength that causes otherwise solid soil to behave temporarily as a viscous liquid. The phenomenon occurs in water-saturated unconsolidated soils affected by seismic S waves (secondary waves), which cause ground vibrations during earthquakes. Although earthquake shock is the best known cause of liquefaction, certain construction practices, including blasting and soil compaction and vibroflotation (which uses a vibrating probe to change the grain structure of the surrounding soil), produce this phenomenon intentionally.
