1) Development and fall of tension during depolarization in the bullfrog atrial muscle were studied using a double gap voltage clamp arrangement. 2) Phasic and tonic tension developments and the following decay were noticed in the tension produced by depolarizing pulse of different durations and amplitudes. The phasic component appeared in response to a short-lasting pulse (0.1-0.2 sec), and re...

Grand-canonical transition-matrix Monte Carlo simulation is applied to analyze the effect of molecular association on the vapor–liquid coexistence and interfacial behavior of square-well based dimerizing fluids. Finite-size scaling techniques are implemented in conjunction with histogram reweighting to determine the infinite-system surface tension from a series of finite-size simulations. The e...

BACKGROUND Fixation strength of metal and bioabsorbable interference screws has not been evaluated while varying the anterior cruciate ligament graft tension angle. HYPOTHESIS There is no difference in fixation strength between 2 types of interference screws for anterior cruciate ligament graft fixation while the graft tension angle is varied relative to the femoral tunnel. STUDY DESIGN Con...

limit to the tension reinforcement ratio in flexural high strength reinforced concrete (hsrc) members isbased on the requirement that tension failure as sufficient rotation capacity are ensured at ultimate limit state.however, the provisions for the total amount of longitudinal reinforcement ratio ( and ) are not associated withany rational derivation. in this paper, a quantitative measure to e...

limit to the tension reinforcement ratio ( ρ) in flexural high strength reinforced concrete (hsrc) members is based on the requirement that tension failure as sufficient rotation capacity are ensured at ultimate limit state. however, the provisions for the total amount of longitudinal reinforcement ratio ( ρ and ρ’) are not associated with any rational derivation. in this paper, a quantitative ...

The bending strength of a wide variety of bony types is shown to be nearly linearly proportional to Young's modulus of elasticity/100. A somewhat closer and more satisfactory fit is obtained if account is taken of the variation of yield strain with Young's modulus. This finding strongly suggests that bending strength is determined by the yield strain. The yield stress in tension, which might be...

Although many monogenic diseases are understood based upon structural changes of gene products, less progress has been made concerning polygenic disease mechanisms. This article presents a new interdisciplinary approach to understand complex diseases, especially their genetic polymorphisms. I focus upon primary open angle glaucoma (POAG). Although elevated intraocular pressure (IOP) and oxidati...

The tension test method of strip steel on stretching winding straightener tension roll group was elaborated. The material and paster form of resistance strain foil in tension test sensor were designed. The measure circuit of tension test sensor was designed. The material and structural form of elastic body of tension test sensor were designed. Strength computation was made on elastic body of te...

The purpose of this research was to experimentally characterize the flexural and tensile characteristics of fiber-reinforced Very High-Strength Concrete (VHSC) panels. The panels were made with a unique mix of cementitous materials achieving compressive strength of 26,000 psi (180 MPa) or greater. VHSC panels were reinforced with polypropylene fibers of 1 inch (25.4 mm) in length and Polyvinyl ...
