Research Progress of Effect of Stabilizer on Melting Resistance of Ice Cream

Shipin gongye ke-ji, 2023
The resistance to melting is an important indicator of the quality of ice cream. During transport, storage and distribution, poorly melting resistance ice cream will inevitably become deformed due to fluctuations in ambient temperature, which in turn ...

'Calving laws', 'sliding laws' and the stability of tidewater glaciers [PDF]

, 2007
A new calving criterion is introduced, which predicts calving where the depth of surface crevasses equals ice height above sea level. Crevasse depth is calculated from strain rates, and terminus position and calving rate are therefore functions of ice ...
