Use of cryopreserved semen has become an important tool in assisted reproduction but freezing and thawing cause sub-lethal damage to spermatozoa. This is d... Raj,Kumar,G.,... - 《Molecular Biology Reports》 被引量: 53发表: 2010年 Freeze-thaw fracturing in building granites It's required ...
advantage of the study of granite stone of vernacular buildings belonging to north-eastern region of Portugal, an enlarged experimental program on the characterization of the physical and mechanical properties of distinct types of granites before and after the freeze and thaw cycles was carried out. ...

Furthermore, the degradation of the granite caused by weathering processes was evaluated by a damage variable determined in terms of porosity. It is obvious that deterioration of the granites increases steadily with an increasing number of freeze-thaw cycles. The biggest effect of chemical processes ...
Freeze-thaw cyclesThe effect of freeze-thaw cycles (FTC) on the flexural strength of granite panels is investigated in this paper. Specimens from three different types of Australian granite were sampled. Fifteen specimens were used as control (unweathered) specimens while another 36 specimens were ...

As the number of freeze-thaw cycles increases, the rate of P-wave velocity decreases gradually. The peak stress loss rate of rock with different crack length increases in the form of power function with the increase of freeze-thaw cycles. The peak strain changes in the form of quadratic ...
