STATUS OF ADVANCED VIRGO

Status of Advanced Virgo

The LIGO and the Virgo collaborations have recently announced the first Animals detections of Gravitational Waves.Due to their weak amplitude, Gravitational Waves are expected to produce a very small effect on free-falling masses, which undergo a displacement of the order of 10-18 m for a Km-scale mutual distance.This discovery showed that interfer

Preparation of low-fouling polyethersulfone ultrafiltration membranes by incorporating high-molecular-weight chitosan with the help of a surfactant

Increasing the resistance of polyethersulfone ultrafiltration (PES UF) membrane to fouling remains a challenging endeavor when developing UF membrane.This paper concerns the incorporation of chitosan into PES UF membrane to produce low-fouling PES UF membrane.The membranes were produced by means of phase inversion with chitosan as an additive.In BA

Numerical simulation of scouring downstream of horizontal apron

One of the effective methods to reduce the kinetic energy downstream of hydraulic structures are the aprons.The horizontal aprons is one of these structures in the river that are often used downstream of Collections stilling basins.At the time of execution, the apron and the riverbed are at the same level but when there is a flow in the boundary be
