A simple method for quantifying the humic content of commercial products

A Simple Method for Evaluating the Cleaning Power of Commercial Detergents

Commercial detergents, in spite of their various names and marks, are used to remove foreign matter (dirt) from substrate. Following removal of dirt from the surface, it is necessary to prevent redeposition, so the detergent must have supending power. In this experimental work, a simple method has been developed to evaluate the cleaning power of commercial detergents. The method, showing th...

A new standardized method for quantification of humic and fulvic acids in humic ores and commercial products.

Increased use of humic substances in agriculture has generated intense interest among producers, consumers, and regulators for an accurate and reliable method to quantify humic acid (HA) and fulvic acid (FA) in raw ores and products. Here we present a thoroughly validated method, the new standardized method for determination of HA and FA contents in raw humate ores and in solid and liquid produ...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
