Shear Response of Members without Shear Reinforcement—Experiments and Analysis Using Shear Crack Propagation Theory (SCPT)

Applied Sciences, 2021
The determination of the ultimate shear capacity and the identification of the corresponding load-carrying mechanisms of concrete members without shear reinforcement has been an ongoing research topic for over 100 years. Based on a full mechanical model,

For your eyes only: Effect of confederate's eye level on reach-to-grasp action

Frontiers in Psychology, 2014
Previous studies have shown that the spatio-temporal parameters of reach-to-grasp movement are influenced by the social context in which the motor action is performed.

Applying Computer Software to Investigate the Effect of Dowel Bar Distribution on Concrete Pavement's Flexural, Bearing Stresses, and Deflection

Revista Ingeniería de Construcción
Cement concrete pavement, often known as rigid pavement, is a type of road structure that provides a durable surface for automotive traffic. In rigid pavements, stresses due to traffic loads are conveyed by slab action, as opposed to the grain-to-grain ...

New Insights Into the Three‐Dimensional Mechanics of the Flagellar Beat Cycle

Cytoskeleton, EarlyView.
ABSTRACT Advances in imaging at the molecular scale have provided greater detail concerning the three‐dimensional structure of the ciliary/flagellar axoneme. Additionally, it has recently been confirmed that electrostatic forces regulate the dynein‐tubulin interaction at the microtubule binding domain (MTBD) of dynein, and at the junction of the nexin ...
