Shear Strength Test Of Hefei Expansive Soil Under Low Stress Conditions With Controlled Suction, Hou Chaoqun, Zhang Rongjian, Li Yongxin

Journal of China & Foreign Highway

Topsoil slide and instability of expansive soil slopes may occur under variable saturation conditions.In order to study the strength characteristics of unsaturated expansive soil under low stress conditions，several different matrix suction and stress conditions were set by unsaturated triaxial apparatus.The triaxial shear test of Hefei expansive soil was carried out，and the test data were analyzed.The test results show that when the net confining stress on the expansive soil continues to weaken，the stress-strain curve transitions from strain hardening to strain softening.The strength of unsaturated expansive soil increases with increasing matrix suction.The shear strength of shallow expansive soil shows a significant reduction …

A Review Of Anthropological Adaptations Of Humans Living In Extreme Conditions And Health Implications, Brad N. Nisipeanu, Robert Lalonde

Human Biology Open Access Pre-Prints

Understanding gene variations in people living under extreme conditions has the potential of curing diseases caused by exposure to heat, cold, fatty diets, hypoxia, and pathogens. One candidate gene associated with heat resistance is ACE1, encoding angiotensin-converting enzyme 1. Associations have also been made between cold resistance or fatty diets and polymorphisms of several genes including ACTN3, encoding alpha-actinin-3, and CPTIA, encoding carnitine palmitoyltransferase 1A. A prominent role in resistance to hypoxia has been given for polymorphisms of EPAS1, encoding endothelial PAS domain protein 1, and EGLN1, encoding Egl-9 family hypoxia inducible factor 1. Variants conferring human resistance to pathogens …
