A series of composites based on nanohydroxyapatite (nHAp) and natural polysaccharides (PS) (nHAp/agar, nHAp/chitosan, nHAp/pectin FB300, nHAp/pectin APA103, nHAp/sodium alginate) was synthesized by liquid-phase two-step method and characterized using nitrogen adsorption-desorption, DSC, TG, FTIR spectroscopy, and SEM. The analysis of nitrogen adsorption-desorption data shows that composites wit...

results the batch kinetics experiments showed that nom adsorption by the adsorbents followed the pseudo-second order model. results showed that the acidic ph is optimum for adsorption of nom by smz. conclusions the findings of this study show that natural zeolite modified with sodium dodecyl sulfate, as a cationic surfactant, is a promising adsorbent for removal of nom. materials and methods in...

An experiment with different filter beds and macrophytes was carried out to study their phytoremediation capacity on the efficiency of domestic wastewater treatment through constructed wetland (CW) from November March 2017-18 at University Agricultural Sciences, Dharwad campus, Karnataka. Twenty combinations involving five types (FB-1: gravel, FB-2: gravel-sand-gravel, FB-3: gavel-sand-brick-gr...

Synthetic aperture radar (SAR) images due to the usage of coherent imaging systems are affected by speckle. So lots of despeckling filters have been introduced up to now to suppress the speckle. Hence, objective and subjective evaluation of the denoised SAR images becomes a necessity. Thereby lots of objective evaluating estimators are introduced to evaluate the performance of despeckling filte...

Abstract The present work aimed to evaluate the overall hydro-geological status of Indpur block, Bankura district, West Bengal, India. Despite having adequate annual precipitation, south-western districts state India, are considered be a significantly water-stressed area state. This is because unfavorable geological setting near subsurface occurrence impervious lithology and inundated nature su...

The Bundelkhand region of Central India has been facing increasing severity droughts, water-level depletion and deterioration in water quality. In this perspective, an attempt made for a qualitative evaluation surface groundwater resources belonging to the rural environment understand contaminant’s source probable human health risk due intake available water. samples collected from were analyse...

Target detection is important content in Synthetic Aperture Radar (SAR) image applications. There is a common target detection method, which is called the Constant False Alarm Ratio (CFAR) detector. But it must satisfy the condition under strong contrast ratio between target area and background clutter area. In fact, it is very difficult for SAR images to satisfy the condition. In order to enha...

In superconformal filling of copper-chip interconnects, organic additives are used to fill high-aspect-ratio trenches or vias from the bottom up. In this study we report on the development of intermolecular potentials and use molecular dynamics simulations to provide insight into the molecular function of an organic additive (3-mercaptopropanesulfonic acid or MPSA) important in superconformal e...
