This paper investigates the wave transmission through artificial reefs utilised as low-crested breakwaters to mitigate coastal erosion and reduce energy. The study utilises DualSPHysics smoothed particle hydrodynamics (SPH) solver evaluate effectiveness of such structures. Wave coefficients were computed for various reef configurations conditions. Results indicate that shifted configuration pro...

The main objective of the present study was to formulate gastroretentive effervescent sustained release drug delivery systems of risperidone floating tablets with the help of Methocel® K15, Ethocel® standard 7FP premium, Eudragit ® RS100 sustained release polymers to improve its safety profile, bioavailability and patient compliance. Risperidone floating tablets were formulated by wet granulati...

With the aim of extending the use of integrated variational principles on fluid and deckplate to the large deflection analysis of floating roofs, this paper investigates the significance of theflexural and membrane components in the formulations of the deck plate. Applying integratedvariational principles on deck plate and fluid facilitate the treatment of the compatibility ofdeformation betwee...

The necessity to implement solutions that guarantee the protection and recovery of coastal area makes submerged breakwater employment is evaluated as a viable variant application because these works contribute conservation natural aesthetic conditions beaches, which part tourist product marketed. However, parameters intervene in their functional design are not very well established, propitiatin...

In this paper, we investigate the wave damping mechanism by sinusoidal submerged breakwater using a half-linear Shallow Water Equations (SWE). We solve equations analytically multi-scale expansion method to obtain elevation profile over with specific height and length. Then, get information about how much caused breakwater, derived analytical solution reflection transmission coefficient. Furthe...

this study was performed to design bilayer regioselective floating tablets of atenolol and lovastatin to give immediate release of lovastatin and sustained release of atenolol. bilayer floating tablets comprised two layers, i.e immediate release and controlled release layers. the immediate release layer comprised sodium starch glycollate as a super disintegrant and the sustained release layer c...

Carvedilol (CVD) is an antihypertensive agent with a short half-life, pH-dependent solubility, and narrow absorption window. The purpose of this research was to prepare a floating-drug delivery-system of carvedilol to increase its half-life. The present study investigates the preparation of carvedilol-floating microspheres, evaluates the floating-drug delivery-system (FDDS) (by scanning electro...
