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...

Effective Polarity of Frozen Solvent Glasses in the Vicinity of Dipolar Solutes
gene therapy plasmid DNA galactosylated poly(L-lysine) pharmacokinetics hepatic uptake
2016/5/23
The polarity of frozen organic solvent glasses is found to be substantially larger than that of liquid solvents at room temperature. The extent of this increase depends on the dipolar character of bot...
Frozen Oceans by scientist David N. Thomas is a glossy, well-produced book with nearly 200 color figures and photos, an introduction to polar and subpolar pack ice regions of the northern and southern...
Convergence of frozen Gaussian approximation for high frequency wave propagation
Convergence of frozen Gaussian high frequency wave propagation
2011/2/25
The frozen Gaussian approximation provides a highly efficient computational method for high frequency wave propagation. The derivation of the method is based on asymptotic analysis. In this paper, fo...
Determining the Critical Temperature and Number of Frozen Layers in a Two-Dimensional Bed of Vibrating Hard Spheres Using a Global Equation of State
Critical Temperature Number of Frozen Layers Two-Dimensional Bed of Vibrating Hard Spheres
2010/11/25
Using a global equation of state, empirically derived by Luding, we ac-curately model the density profile of a two-dimensional hard sphere system with diameter D and mass m under gravity with a given ...
Different photolysis kinetics at the surface of frozen freshwater vs. frozen salt solutions
Different photolysis kinetics frozen freshwater frozen salt solutions
2010/11/30
Reactions at air-ice interfaces can proceed at very different rates than those in aqueous solution, due to the unique disordered region at the ice surface known as the quasi-liquid layer (QLL) . The p...
Particle-scale structure in frozen colloidal suspensions from small angle x-ray scattering
Particle-scale structure frozen colloidal suspensions small angle x-ray scattering
2010/11/19
During directional solidification of the solvent in a colloidal suspension, the colloidal particles segregate from the growing solid, forming high-particle-density regions with structure on a hierarch...
Frozen soil parameterization in a distributed biosphere hydrological model
Frozen soil parameterization distributed biosphere hydrological model
2010/4/7
In this study, a frozen soil parameterization has been modified and incorporated into a distributed biosphere hydrological model (WEB-DHM). The WEB-DHM with the frozen scheme was then rigorously evalu...
High Frequency Spectroscopic Study of the Bound State of Water in PEG–H2O System during Heating from Frozen State
High Frequency Spectroscopic Study the Bound State of Water in PEG–H2O System Frozen State
2010/9/17
The bound state of water in PEG (polyethylene glycol)–H2O systems was studied by using HFS and DSC methods. Samples with the mixing ratios EO:H2O = 1:1 (a) and 1:10 (b), where EO indicates the ethylen...
A one-dimensional mathematical model is used to simulate the process of
snow-melt infiltration in unsaturated frozen silt. Hydraulic and thermal parameters
are mainly based on data given in the lite...
The infiltration of snow melt water on arable land influences both the water
storage and the nutrient budget. The infiltration rate during thawing was
assumed to depend on the ice content of the soi...
