Limit Equilibrium Method-based Shear Strength Prediction for Corroded Reinforced Concrete Beam with Inclined Bars.

Shear strength is a widely investigated parameter for reinforced concrete structures. The corrosion of reinforcement results in shear strength reduction. Corrosion has become one of the main deterioration factors in reinforced concrete beam.

Evaluation of a new type of wound dressing made from recombinant spider silk protein using rat models.

This study investigates the feasibility of recombinant spider silk protein as a wound-dressing material for coverage of deep second-degree burn wounds using an animal model. Sixty Sprague-Dawley (SD) rats were randomly divided into four groups (15 rats in each group). Two types of recombinant spider silk proteins, pNSR-16 and pNSR-32, as well as collagen (as a control) were applied on the wound; the fourth group was left untreated as a negative control.
