Reactive Powder Concrete (RPC) is one of the most advanced recent high compressive strength concrete. This work explored the effects of using glass waste as a fractional replacement for fine aggregate in reactive powder concrete at levels of 0%, 25%, 50%,... see more

Background: The body of research on field based player-surface interaction consists of some contradictory findings and the comparison of male and female physiological responses on different surfaces is limited. Objective: The study investigates the influe... see more

In a constrained-layer damping system, a thin layer of a viscoelastic material is applied over the vibrating substrate. and covered with a stiff constraininglayer of a metal or a fibre-reinforcedplastic. Several viscoelastic materials based on elastomeric... see more

The purpose of this study is to develop a low cost, locally produced concrete mixture with optimum marble content. The resulting mixture would have enhanced strength properties compared to the non-marble reference concrete, and improved radiation shieldin... see more

The planning fiber optic properties are one of the important fields in fiber optic communication systems. In this article a software simulation proposed to study the main properties of single mode fiber and impact on the output power. This is because fibe... see more

Background:In diagnostic radiology lead apron, are usually used to protect patients and radiology staff against ionizing radiation. Lead apron is a desirable shield due to high absorption and effective attenuation of x-ray photons in the diagnostic radiol... see more

Due to differences of rock properties such as porosity, permeability and compressibility between different regions in the porous media, pressure gradients are induced between those different regions and lead to local fluid flow. When seismic wave propagat... see more

The attenuation properties of Delhi & surrounding region have been investigated using 62 local earthquakes recorded at nine stations. The frequency dependent quality factors Qa (using P-waves) and Qb (using S-waves) have been determined using the coda nor... see more

In several recent reports, we have explained the frequency dependence of the apparent seismic quality-factor (Q) observed in many studies according to the effects of geometrical attenuation, which was defined as the zero-frequency limit of the temporal at... see more
