Geologists compared the spatial and temporal distribution of methane concentrations in the air of northern Siberia with geological maps. The result: the methane concentrations in the air after last ye...
Thawing permafrost affects Alaska's land-to-ocean river flows（图）
Thawing permafrost Alaska land-to-ocean river flows
2020/1/21
A new analysis of the hydrologic cycle across the North Slope of Alaska reveals significant increases in subsurface runoff and cold season discharge -- changes scientists say reflect thawing permafros...
Effect of thawing method on bull sperm survival in ejaculates frozen in 4 ml and 8 ml volumes
bovine semen large volumes semen processing sperm quality parameters
2018/11/23
The aim of this study was to evaluate the effect of different thawing protocols (slow (P1), medium (P2), and fast (P3)) on percentage of motile sperm (MOT) and percentage of sperm cells with intact me...
The effect of curvature in thawing models
Cosmology and Extragalactic Astrophysics (astro-ph.CO) General Relativity and Quantum Cosmology (gr-qc)
2010/12/29
We study the evolution of spatial curvature for thawing class of dark energy models. We examine the evolution of the equation of state parameter, $w_\phi$, as a function of the scale factor $a$, for t...
Numerical Modelling of Phase Change in Freezing and Thawing Unsaturated Soil
Numerical Modelling Phase Change Unsaturated Soil
2009/10/26
This paper presents a new method for handling the phase change process in
numerical simultations of freezing and thawing soils. Moisture and heat transfer
in soils subjected to both freezing and tha...
Influence of Sub-Debris Thawing on Ablation and Runoff of the Djankuat Glacier in the Caucasus
Sub-Debris Thawing Ablation and Runoff Djankuat Glacier
2009/10/22
Superficial moraines grew in size during the entire 32-year-long period of direct
monitoring of water and ice balance of the Djankuat Glacier in the Caucasus.
The total area of debris cover on the g...
Estimation of permafrost thawing rates in a sub-arctic catchment using recession flow analysis
permafrost thawing rates recession flow analysis sub-arctic catchment
2009/7/22
Permafrost thawing is likely to change the flow pathways taken by water as it moves through arctic and sub-arctic landscapes. The location and distribution of these pathways directly influence the car...
Effect of Freezing and Thawing on the Histology and Ultrastructure of Buffalo Muscle
Freezing Buffalo Muscle Thawing Histology Ultrastructure
2016/4/18
Histology and transmission electron microscopy studies were carried out on buffalo muscles that were subjected to repeated freeze-thaw cycles at -10 and -18 C. In the first freeze thaw cycle (-10 C) s...
In vitro Fertilization and Development of Pig Oocytes Inseminated with Boar Sperm by Different Sperm Washing Media after Thawing of the Frozen Straws
IVF Boar Sperm Washing Media 5 ml Frozen-straw Oocytes

This study was carried out to investigate in vitro fertilization and development of in vitro matured pig oocytes inseminated with the Duroc boar sperm by different sperm washing media after thawing of...
Physico-Chemical Properties of Illite Suspensions after Cycles of Freezing and Thawing
Illite-Type Clays Plasticity Pretreatment With Cold Thermal Analysis Thixotropy Viscosity
2011/12/7
Abstract: The effect of freezing and thawing on the rheological behavior of illite suspensions was studied by examining viscosity and plasticity. Stability of suspensions was characterized by a hyster...
