Sake In some regions, the first sips of toso are taken in order of age, from the youngest to the eldest. Sake , also spelled "saké" ( ), also referred to as a Japanese rice wine, is an alcoholic beverage made by fermenting rice that has been polished to remove the bran. Unlike wine, in which alcohol is produced by fermenting sugar that is naturally present in fruit, typically grapes, sake is produced by a brewing process more akin to that of beer, where starch is converted into sugars which ferment into alcohol. The brewing process for "sake" differs from the
Converted-wave analysis Converted-wave analysis During seismic exploration, P-waves (also known as primary or compressive waves) penetrate down into the earth. When a P-wave hits an interface (e.g., solid-liquid), it can reflect upwards as an S-wave (also known as a secondary, shear or transverse wave). Other P-wave to S-wave (P-S) conversions can occur, but the down-up conversion is the primary focus. Unlike P-waves, converted shear waves are largely unaffected by fluids. By analyzing the original and converted waves, seismologists obtain additional subsurface information, especially due to (1) differential velocity (V/V), (2) asymmetry in the waves' angles of incidence and reflection and (3) amplitude
