Low-alcohol beer This is the preferred method because raising the temperature this late in the brewing process can greatly affect the flavor of the brew. If brewers decide to convert their brew to a non-alcoholic brew they must consider the volume of liquid they have lost during the removal of the alcohol. Typically the volume is reduced by roughly 4%, and to compensate water is added. Another tip would be avoiding using sugar from maize; this simply increases the alcohol content without adding to the flavor or body of the beer. Once the alcohol is removed, one proceeds with the normal finishing
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
