in the present study, micellar-enhanced ultrafiltration (meuf) was used to remove manganese (mn) (ii) from synthetic wastewater. the effects of different operational conditions on the filtration performance of meuf or the membrane were studied. it was found that the transmembrane pressure has a major influence on the permeate flux and an insignificant effect on the rejection coefficient. the pe...

It is a risky task to attempt to predict the direction that DNA barcoding and its applications may take in the future. In a very short time, the endeavor of DNA barcoding has gone from being a tool to facilitate taxonomy in difficult to identify species, to an ambitious, global initiative that seeks to tackle such pertinent and challenging issues as quantifying global biodiversity, revolutioniz...

BACKGROUND The State of Bavaria is involved in a research program that will lead to the construction of a DNA barcode library for all animal species within its territorial boundaries. The present study provides a comprehensive DNA barcode library for the Geometridae, one of the most diverse of insect families. METHODOLOGY/PRINCIPAL FINDINGS This study reports DNA barcodes for 400 Bavarian geo...

The distinction between informational and computational equivalence of representations, rst articulated by Larkin and Simon (1987) has been a fundamental principle in the analysis of diagrammatic reasoning which has been supported empirically on numerous occasions. We present an experiment that investigates this principle in relation to the performance of expert graph users of 2 × 2 ‘interactio...

عملکرد یک نمودار x-bar معمولاً تحت این فرض که انحراف معیار فرآیند به خوبی تخمین زده شده و تغییر نمی کند، بررسی می شود. البته این فرض در عمل معمولاً درست نبوده و نمودارهای x-bar در برابر اشتباهات تخمین انحراف معیار فرآیند یا تغییرات انحراف معیار پایدار نیستند. در این تحقیق، به بررسی یک نمودار کنترل میانگین متحرک موزون نمایی با بازه های نمونه گیری متغیر برای کنترل تغییرات در میانگین فرآیند پرداخته ...
