Repeated Freeze–Thaw Cycles in Cryosurgery

Nature, 1968
FREEZING temperatures have been in use in surgery for many years as a means of local tissue destruction. Recent experimental investigation has shown that such freezing will give a reproducible area of cell death provided factors such as the temperature and the duration of application are constant.

Measuring Total Mercury Through Freeze–Thaw Cycles

Bulletin of Environmental Contamination and Toxicology, 2023
Total mercury (THg) analysis of fish tissue requires the samples to be frozen for long-term storage or analyzed immediately after the fish sample has been obtained. Such rigid field sampling protocols do not account for the logistical challenges that can occur if sampling is conducted in remote areas or collaboratively via community-based monitoring ...

Effects of freeze–thaw cycles on the texture of Nanguo pear

Journal of Texture Studies, 2022
AbstractFreezing is a way to preserve the quality of fruit for a long time. Nanguo pear stored at low temperature is prone to browning and lignification. In this study, freeze–thaw cycles were used to simulate the temperature fluctuation in the process, storage, and transportation.

Freeze-Thaw Cycle and Rockfall Monitoring

2013
Among several weathering processes that may contribute to rock fall generation, a particular issue is related to freeze-thaw cycles. Several studies claim that many rock falls originate from thawing of the fractured bedrock during seasonal freezing (Matsuoka and Marton Permafrost Periglac Process 19(2):195–210, 2008; Matsuoka Cold Reg Scid Technol 17(3)

Colloid-Facilitated Mobilization of Metals by Freeze–Thaw Cycles

Environmental Science & Technology, 2014
The potential of freeze-thaw cycles to release colloids and colloid-associated contaminants into water is unknown. We examined the effect of freeze-thaw cycles on the mobilization of cesium and strontium in association with colloids in intact cores of a fractured soil, where preferential flow paths are prevalent. Two intact cores were contaminated with

The Frequency of Freeze-Thaw Cycles

Journal of Applied Meteorology, 1974
Abstract Data from 1300 climatic summaries are used to construct a map for the conterminous United States showing the annual frequency of freeze-thaw cycles. Seasonal maps, as a percentage of the annual map, are based on a smaller number of stations. The highs of freeze-thaw activity, about 250 days per year, are in the mountainous regions of the West ...
