ground water is the major source of drinking water in rural and semi-urban areas of assam. it contains an excessive amount of iron (1 to 10 mg/l). people living in rural and semi-urban areas of assam uses indigenous household iron filter units – developed using community prepared wooden charcoal (cpwc) and river sand (rs) as filter media. cpwc and rs processed and respectively termed as process...

The incorporation of brown algae into biopolymer beads or foams for metal sorption has been previously reported. However, the direct use of these biomasses for preparing foams is a new approach. In this study, two kinds of porous foams were prepared by ionotropic gelation using algal biomass (AB, Laminaria digitata) or alginate (as the reference) and applied for Pb(II) sorption. These foams (ma...

BACKGROUND Variable decelerations are the most frequent fetal heart rate changes that are related to labor. The objective of the study was to estimate the impact of non-significant variable decelerations (NSV) appearing during the latent phase of labor on delivery mode and neonatal outcome. METHODS Women at term, who were in the latent phase of labor and had a singleton pregnancy, were prospe...

The combination of post-column derivatisation and visible detection are regularly employed in ion chromatography (IC) to detect poorly absorbing species. Although this mode is often highly sensitive, one disadvantage is the increase in repeating baseline artifacts associated with out-of-sync pumping systems. The work presented here will demonstrate the use of a second generation design paired e...

THE events taking place as a patient emerges from anaesthesia are not well understood and several theories have been advanced to explain the phenomena that occur during this period. However, their exact cause will probably not be found as long as the basic mechanisms of anaesthesia are not entirely clear. A small number of clinical facts are, nevertheless, well established; an example is the we...

Relevance of mode coupling to energy/information transfer during protein function, particularly in the context of allosteric interactions is widely accepted. However, existing evidence in favor of this hypothesis comes essentially from model systems. We here report a novel formal analysis of the near-native dynamics of myosin II, which allows us to explore the impact of the interaction between ...

When simulating hybrid systems using switched bond graphs, the initialization of new modes is made by using a generalization of the principle of momentum conservation. Here it is shown how to use causality propagation to get an efficient initialization algorithm. By looking at causal paths, set of variables that have to be initialized simultaneously are found. Furthermore, it is shown how impul...

The influence of viscoelastic thermal compression (VTC) of wood on bonding performance was studied. Mode-II (shear mode) fracture of the bonded interphase was performed using the overnotched and end-notched flexure methods. The study examined four groups of specimens; a control and VTC specimens with three different degrees of densification (63, 98, and 132%). The specimens were bonded with phe...
