A field investigation was carried out in Kotchandpur to find the comparative nutrient status, viz. pH, N, P, K, S, Zn and B. 70 soil samples from four representating series namely Ghior, Gopalpur, Iswardi Sara were collected analysd regional laboratory of SRDI, Daulatpur, Khulna. The pH indicated neutral slightly alkaline nature except some soils medium low land under Ghior high Ishwardi that a...

A pilot scale field trial for a novel metal removal technology in the treatment of mine waters was performed using mine water from White Tip, part of the former Snailbeach lead mine in Shropshire, United Kingdom (UK). The water is circum-neutral pH and contains elevated zinc (Zn), cadmium (Cd) and lead (Pb). The novel treatment process is based on ion exchange (IE) using a bespoke mesh in a rot...

The objective of this study was to test the hypothesis that serotonin O-sulphate (5-HT-SO4) could be quantified in human plasma using modern liquid chromatography-mass spectrometry (LC-MS) method as well as develop and validate that method. First, a suitable LC-MS method for detection of 5-HT-SO4 in human plasma samples was developed and validated. Second, a Pilot phase involving four healthy v...

Dermatan sulfate increases the rate of inhibition of thrombin by heparin cofactor II (HCII) approximately 1000-fold by providing a catalytic template to which both the inhibitor and the protease bind. Dermatan sulfate is a linear polymer of D-glucuronic acid (GlcA) or L-iduronic acid (IdoA) alternating with N-acetyl-D-galactosamine (GalNAc) residues. Heterogeneity in dermatan sulfate results fr...

Two novel coordination polymers [Ag16(SO4)8][Ag4(SO4)2]3(L1)12·nH2O (n = 72) (1) and [Ag10(SO4)5(L2)4(H2O)2]·8H2O (2) based on conformationally variable oligo-α-heteroarylsulfanyl ligands 2-(pyrazin-2-ylthio)-6-(pyridin-2-ylthio)pyrazine (L1) or 2,6-bis(pyrazin-2-ylthio)pyrazine (L2) and sulfate-templated high-nuclearity Ag(I) clusters as structure-building units (SBUs) have been synthesized un...

Despite its ubiquity in nature, SO4 22 as an isolated dianion has never been detected because of its electronic instability as a result of the two negative charges. This study shows how the first few waters solvate and stabilize an isolated SO4 , molecule-by-molecule, using photodetachment spectroscopy and theoretical calculations. We find that the minimum number of water required to stabilize ...

Possible application of a locally isolated environmental isolate, Acinetobacter haemolyticus to remediate Cr(VI) contamination in water system was demonstrated. Cr(VI) reduction by A. haemolyticus seems to favour the lower concentrations (10-30 mg/L). However, incomplete Cr(VI) reduction occurred at 70-100 mg/L Cr(VI). Initial specific reduction rate increased with Cr(VI) concentrations. Cr(VI)...

A Zr-based MOF, NU-1000, comprised of Zr6 nodes and tetratopic pyrene-containing linkers is studied for adsorption and extraction of SO4(2-) from water. The adsorption capacity and uptake time of SO4(2-) in NU-1000 is determined at varying concentrations to give an overall maximum adsorption capacity of 56 mg SO4(2-) per g of MOF. Selective adsorption of SO4(2-) by NU-1000 in the presence of ot...

The present investigation was aimed to study the distribution, enrichment and accumulation of heavy metals in soil and Vigna mungo (Black gram, var. Pant U-30) after irrigation with distillery wastewater. A field experiment was conducted in the experimental garden of Gurukula Kangri University, Haridwar during the year 2012 and 2013. Treatments of distillery wastewater viz. 20%, 40%, 60%, 80% a...
