Aiming to mitigate impact of the uncertain boundary conditions setting on the underwater radiated noise calculation, the numerical prediction method of calculating the underwater radiated noise of a waterjet by the one-step Dust Pans boundary element method was explored.First, the transient flow field of the waterjet was calculated on the basis of

Background: In sub-Saharan African countries, women face a high risk of obstetric fistulas.In Malawi, the prevalence rate is 1 per 1000 women.Studies suggest that several obstacles exist that prevent obstetric fistula patients from getting timely treatment for their condition.Aim: The aim of this article was to find out the factors that delay the t

Buckling Restrained Braces (BRBs) are installed in buildings to control lateral displacements caused Accessories by seismic events.Although, conventional BRBs have various advantages comparing to ordinary bracing systems, their high weight and dimensions because of the restraining units is a dominant drawback.In this paper, a new developed type of

Abstract Reactive power dispatch is a vital problem in the operation, planning and control of power system for obtaining a fixed economic load expedition.An optimal dispatch reduces the grid congestion through the minimization of the active power loss.This strategy involves adjusting the transformer tap settings, generator voltages and reactive pow

The dropout rate of engineering students is a concerning problem at the present time in many countries, resulting in difficulties to follow the demand of professionals in certain technological sectors as well as L-Carnosine an associated negative economic impact.This study identifies a number of factors affecting the motivation degree of current el
