Shear Moduli and Damping of Cohesive Soils under Earthquake Loads

To investigate the dynamic properties of soils under earthquake loading conditions, a series of cyclic triaxial compression tests vas carried out on undisturbed saturated samples of cohesive soils from Tianjin. It has come to the conclusion that variation of damping ratio, as well as shear modulus, with strain amplitude may be expressed by an empirical formula. Its normalized form can be shown by a family of curves or a band zone with shrunken ends. New empirical equations used for evaluating elastic or initial shear modulus G0 and maximum shear stress τmax have been suggested. For the two parameters, some comparisons between field and laboratory test values and between the results of cyclic and static triaxial compression tests under conditions of the same loading levels have been made

Complementary and Alternative Therapy with Traditional Chinese Medicine for Infertility

Infertility results in a country with a low birth rate and an aging population, and thus there is vested interest in treating this problem by using both complementary and alternative therapies, in addition to conventional western medicine. Traditional Chinese medicine (TCM) has been widely used for healthcare in the Eastern world for thousands of years. This chapter describes the evidence to support the role of TCM in the management of male and female infertility
