Rapid expansion in urbanization and industrialization coupled with recent drought conditions has triggered unplanned groundwater development leading to severe stress on groundwater resources in many urban cities of India, particularly cities like Nanded, Maharashtra. In the quest of tapping drinking water requirement, due to recent drought conditions, people from the city are piercing through entire thickness of shallow basalt aquifers to reach productive deeper granite aquifers. Earlier reports from Nanded and surrounding districts suggest that deeper granite aquifer is contaminated with fluoride (geogenic). The study aimed to find out variations in fluoride concentration in shallow basalt (10–167 m) and deeper granite aquifers (below 167 m) and to find out the relationship between fluoride and other ions. Study suggests that concentration of fluoride in shallow basalt aquifer is within maximum permissible limits of Bureau of Indian Standards and deeper granite aquifer contains as high as 4.9 mg/l of fluoride and all samples from granite aquifers are unfit for human consumption. The groundwater from basalt aquifer is mainly Ca-HCO3−Cl type, and from granite aquifer, it is Ca-Na-Cl type. The correlation plot between F− vs. pH, Na+ and HCO3 − shows a positive correlation and an inverse relationship with Ca2+ in both aquifers. As recommendations, it is suggested that granite aquifers should not be tapped for drinking purposes; however, in drought situations, water from this aquifer should be blended with treated surface water before supplying for drinking purposes. Efforts may be made to utilize 1.35 MCM of rainwater from available rooftop, which is sufficient to cater for the needs of ~40,800 people annually. Most effective defluoridation techniques like electrolytic de-fluoridation (EDF), ion exchange and reverse osmosis may be adopted along with integrated fluorosis mitigation measures. © 2017, Springer International Publishing AG.

Wine was produced using grand naine variety of banana (Musa acuminata). The must was prepared from banana pulp by using water, pectinase (0.0125 %) and sucrose. The must produced had, pH 3.31, titratable acidity (% tartaric acid) 0.28, °Brix 21.0, and reducing sugar (mg/mL) 142.80. Fermentation of both pasteurized and non-pasteurized banana must was carried out by using Baker's yeast (Saccharomyces cerèvisiae). After fermentation, physicochemical and volatile acid analyses of wines were performed. Volatile acid analysis was performed by using gas chromatographic method. The results showed that banana wines from non-pasteurized and pasteurized must respectively had °Brix (5.5 and 6.67), titratable acidity (0.65 and 0.63 %), alcohol (5.94 and 6.43 %) and same pH (3.07). pH and specific gravity were decreased after fermentation process. Total concentrations of determined volatile acids were around two fold higher in wine from non-pasteurized must than pasteurized must. Pasteurization of must gives wine with slightly high % of alcohol and low concentration of volatile acids. © Global Science Publications.

In this paper, method is proposed for finding an optimal solution for transportation problem. Transportation cost, supply and demand are considered in the intervals. Separation method is proposed which is based on zero point method. Using interval membership function we have checked optimality of the solution. Also, this method is compared with triangular membership function. Finally, the feasibility of the proposed method is checked with a numerical example. © EuroJournals Publishing, Inc. 2011.

We report the synthesis of the Benzimidazole ligands, 2-[(1H Benzimidazole-2-yl)-methyl]-phenol, 2-[(1H-Bezimidazole-2yl)]-bromo-phenol, 2-[(1H-Benzimidazole-2yl)]-4-bromo-6-iodo-phenol, 2-[(1H-Benzimidzole-2yl)]-4,6-diiodo-phenol and their Cu(II) metal complexes, characterization and antimicrobial activity. The structure of the ligands and their complexes was investigated using, FT-IR, UV-Vis, TGA/DTA, X-ray Diffferaction. In the complexes, all the ligands behave as bidentate ligands, the oxygen in the ortho position and azomethine nitrogen atoms of the ligands coordinate to the metal ions. Antimicrobial activity of the ligands and metal complexes were tested Aspergillusniger, Aspergillusflavus, Escherichia coli and Bacillus subtilisusing by the disc diffusion method.

Metal chelates of ligand 4-(N-methyl-2, 2-dichloroacetamido) phenyl-2-furoate have been synthesized and characterized by elemental analysis, molar conductivity, magnetic moments, IR, 1H NMR, UV-visible, EPR, TG/DTA and powder XRD. Copper and cobalt complexes have 1:1 stoichiometries while chromium complex has 1:2 stoichiometry. Metal chelates have considerable influence on organic carbon, total nitrogen, phosphorus and potassium content and percent weight loss. After decomposition, C: N ratio of the organic matter was appreciably improved compared to non-decomposed organic matter.

Solid-phase extraction (SPE) of nine polychlorinated biphenyls (PCBs) from transformer oil samples was evaluated using octadecyl (CI8)-bonded porous silica. The efficiency of SPE of these PCBs was compared with those obtained by solvent extraction with DMSO and hexane. Average recoveries exceeding 95% for these PCBs were obtained via the SPE method using small cartridges containing 100. mg of 40. pm CI8-bonded porous silica. The average recovery by solvent extraction with DMSO and hexane exceeded 83%. It was concluded that the recoveries and precision for the solvent extraction of PCBs were poorer than those for the SPE. © 2013 Elsevier Ltd.

House sparrow (Passer domesticus) is the brown and fluffy bird which is widely distributed, most familiar and abundant bird, found in almost in all habitats. (Summer-Smith 1988; Anderson, 2006). Effect of different habitats on its population density was studied from September 2010 to August 2012 at four different habitats such as agriculture field (Chudawa), Purna river, Grassland (Purna-Tadkalas road) and residential colony (Siddharath Nagar). For the study Line Transects and Point Count Methods were used. It was observed that population density was abundant in residential colony and rare in grassland as compare to other habitats. The details of observation are discussed in the text. Copyright © EM International.

Currency (notes and coins) handling by people during transaction is one of the most mobile objects within the community, which has a potential of transmitting pathogens. A survey carried out recently in Nanded city (Maharashtra) revealed heavy contamination of currency notes and coins by important fungal pathogens of plants and man, i.e. Aspergillus niger (60.37%), A. flavus (3.98%), A.nidulans (0.2%), Penicillium citrinum (17.80%), Alternaria tenuis (0.20%), Curvularia pallescens (0.20%), Cladosporium cladosporioides (10.69%), Rhizopus stolonifer (1.04%), an unidentified Aspergillus species .1 (0.20%) and another unidentified Aspergillus species.2 (3.14%), Fusarium sp. (0.20%), Trichoderma viride (0.20%),white sterile mycelium (0.62%) and brown sterile mycelium (0.62%). The study highlights the importance of preventing and controlling fungal contamination of currency notes and coins in public health and plant protection. Currency notes or coins are rarely suspected as infection sources and often not quarantined at airport or seaport terminal. Possible transmission of pathogens or "alien", invasive species through currency across borders or across countries needs to be taken into consideration especially under circumstances of serious outbreak of important disease or when there is a threat of biological warfare.
