The optimal reactive power dispatch (ORPD) is a very important problem aspect of power system planning and is a highly nonlinear, non-convex optimization problem because consist of both continuous and discrete control variables. Since the power system has inherent uncertainty, hereby, this paper presents both of the deterministic and stochastic models for ORPD problem in multi objective and sin...

background chlorhexidine gluconate (chx) is the most common antimicrobial agent used against oral pathogens, however information on its ability to inhibit and disrupt anaerobic single and multispecies biofilms is relatively unknown. objectives the purpose of this study was to test the efficacy of chx for its biofilm inhibition and disruption properties using crystal violet assay. materials and ...

The acid-base equilibria of glycine have been studied in different aqueous solutions of 1,4-dioxane(0-50 % by v/v) using potentiometric method. In this study, the macro and micro protonationconstants of the amino acid and its tautomeric constant have been determined at 25 °C and constantionic strength 0.1 mol dm-3 (NaCl). The protonation and the tautomeric constants of glycine indifferent binar...

this paper presents a new hybrid method for optimal multi-objective reconfiguration in a distribution feeder in addition to determining the optimal size and location of multiple-distributed generation (dg). the purposes of this research are mitigation of losses, improving the voltage profile and equalizing the feeder load balancing in distribution systems. to reduce the search space, the improv...

Abstract Resin flow through multi-ply woven fabrics is affected by the fibre orientation and laminate stacking sequence during impregnation process. This characterised permeability, which measures ability of transferring fluids within a 2D or 3D layered architecture (i.e., porous medium). The work aims to investigate feasibility characterising macro-scale permeability via micro-meso-scale (dual...

The size and length effects of an inclusion on multi-pass copper shaped-wire drawing were investigated. For this purpose, an experimental investigation on optimal die half-angle was conducted. Based on experimental data of optimal die half-angle, wire and inclusion deformations, drawing and hydrostatic stress of copper shaped-wires that contain an inclusion were calculated by two-dimensional fi...

in this commentary the findings from a systematic review that concluded there is no compelling evidence to suggest that implementing complicated, multi-faceted interventions is more effective than simple, single component interventions to changing healthcare professional’s behaviour are considered through the lens of harvey and kitson’s editorial. whilst an appealing conclusion, it is one that ...
