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 ...

Freeze-thaw cycles at Resolute, N.W.T.

1962
Research workers in many fields have been interested in freezethaw cycles in the active layer. They are a phenomenon, however, on which few quantitative data exist, particularly for far northern regions. This paper presents soil-temperature data from Resolute, N.W.T ., for 1960, based on continuous Speedomax records from five levels: air, ground ...

Freezing-Thawing Cycles of Saturated Sand Sample

2023
Freezing and thawing cycles in laboratory were studied. Freezing-thawing cycles were carried out in the laboratory on fully saturated packed sand sample (15 cm in diameter and 20 cm in height). Series of freezing-thawing cycles were conducted with newly designed experimental setup.

Freeze/Thaw Cycling of Motion-Picture Films

SMPTE Journal, 1985
Experimental results and physical considerations are cited that should alleviate concerns about the freeze/thaw cycling of processed motion-picture film. Neither ice crystal formation nor high relative humidities are expected to occur under the recommended storage practices.

Determining freeze-thaw resistance : corelation air voids and freeze-thaw cycles

2008
Determination of air voids characteristics in hardened concrete, and concrete exposing to freezing/thawing cycles help us to determine concrete resistance to freezing with and without deicing agents. Automatic air void analysis sistem for characterising the air void system of hardened concrete require approximately 90 min with minimum 7 days old ...

Freeze-thaw durability estimation of the bridge based on the indoor and outdoor freeze-thaw cycle experiment

2011 International Conference on Electric Technology and Civil Engineering (ICETCE), 2011
The Song hua River Highway Bridge is located in the northeast cold areas, which is affected by the freeze-thaw cycles vulnerably. Both of the indoor rapid freeze-thaw experiment and outdoor natural exposure experiment were taken for the main concrete components of the bridge.

Effects Of Freeze-Thaw Cycling On Soil Erosion

2001
Landscapes evolve as a result of the interactions of topography, climate, hydrology, vegetation conditions, rock-weathering processes, soil conditions, sediment transport and deposition processes, and land use. An integral part of understanding and modeling that evolution must be a knowledge of the spatial and temporal dynamics in soil erodibility and ...

Value of a second freeze-thaw cycle in cryotherapy of common warts

British Journal of Dermatology, 1994
A study of open, randomized, parallel-group design was performed to investigate the impact of a second freeze-thaw cycle on the cure rate, at 3 months, from cryotherapy of common warts on the hands and feet. Cryotherapy was performed at 3-week intervals, and subjects were randomized to receive either one or two freeze-thaw cycles.
