Effect of Span, Load Intensity, and Beam Geometry on Stress and Deflection Behavior of RCC Beams
Abstract: This study investigates the influence of variations in beam geometry, span, load intensity, and permissible stresses on the structural behavior of reinforced concrete beams. Using classical bending and shear stress formulations, the effects of a 20% increase in key parameters were analytically evaluated. Results indicate that a 20% increase in beam span leads to a proportional 20% increase in beam depth, whereas a 20% increase in beam width or permissible …

Ru(III)-Catalyzed Oxidative Cleavage of Ritodrine Hydrochloride: A Kinetic and Mechanistic Study
Abstract: A systematic kinetic and mechanistic study of the oxidation of ritodrine hydrochloride (RTH) with chloramine-T (CAT) in both HClO4 and NaOH media has been carried out at 303 K. In acid medium, the reaction rate is very sluggish to be measured kinetically. Ruthenium (III) chloride ([Ru(III)]) was found to be an efficient catalyst. The reaction rate exhibits a first-order dependence on [CAT]0 in both media. It shows a fractional-order on …

Piezo in Implant Surgery: A Literature Review
Abstract: Dental Implants are Titanium cylinders that are widely used by dentists as prosthesis to replace damaged or lost tooth. The process where the implant locks and attaches itself with the bone is termed as osseointegration. Factors like bone quality and quantity, primary stability of implant, surface characteristics of implant are some of the factors that determine osseointegration of the implant.Acceleration of osseointegration may depend on the removal of negative tissue …
