Northern Reach: Architecture of a Thawing Arctic
As our climate continues to shift, it is fundamental to understanding these unprecedented changes through field research done in biomes most critically impacted. Due to the remoteness and extreme climatic nature of these research stations, they are typically either hastily built flat pack …

Uplift capacity of helical piles in thawing permafrost
… prevalent water migration in the test since slow thawing may lead to higher water contents at the center of the tank where the pile is located. Axial capacities from experiments are compared with predictions from theoretical helical pile capacity equations. Estimates of undrained shear strength …

Experimental investigation of soil volume changes during freezing and thawing
… behaviour of soils during freezing and thawing, with focus on frost heave and thaw settlement. Ground freezing is a natural phenomenon that affects civil engineering projects, especially in cold regions or where artificial ground freezing (AGF) is employed. Freezing causes water in the …

Hydrological and Hydrochemical Responses From Thawing Permafrost in the Canadian Arctic
The objectives of this research are to better understand: (1) how Arctic watersheds respond in terms of hydrological processes to deepening active layers, (2) what the short and long-term changes are to surface water chemistry in watersheds impacted by thermal and physical permafrost disturbances, …

Protection Mechanisms of Excipients on Lactate Dehydrogenase during Freeze-Thawing and Lyophilization
… lactate dehydrogenase (LDH), during freeze-thawing and lyophilization. Cryoprotectants are excipients that protect labile molecules during freezing. Some investigators believe that preferential exclusion is the predominant mechanism to explain the cryoprotection of labile proteins by the …

Mitigation and Evaluation of Alkali-Silica Reaction (ASR) and Freezing and Thawing in Concrete Transportation Structures
… of alkali-silica reaction (ASR) and freezing and thawing (F/T) in concrete transportation structures is presented along with mitigation methods for slowing the rate of deterioration in concrete. A combination of field and laboratory testing confirms ASR deterioration is exacerbated by exposure to …
