The polyfilm manufacturing process involves mono-ethylene glycol (MEG) and ethyl acetate (EA) as the main constituents. The presence of such organic compounds is responsible for the higher toxicity and Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) values of the polyfilm effluent. In our previous studies, isolation and identification of efficient MEG and EA degraders was done. All the physico-chemical parameters were found to be well above the permissible limits prescribed by the Indian Standards Institute (ISI) standards, and toxicity of the effluent was confirmed by using fish assay and pot assay. About 10-20% increase in BOD and COD reduction was obtained with developed microbial consortium as compared to the individual five microbial isolates tested at flask level studies. About 8-18% increase in BOD and COD reduction was observed with developed microbial consortium as compared to the 5% (v/v) sewage and 5% (v/v) cow dung slurry in 12 days. Pilot plant studies were carried out at the 5-l level of polyfilm effluent, and about 99% reduction in BOD and COD was obtained using developed microbial consortium. Physico-chemical levels were reduced significantly in compliance with the prescribed ISI standards showing the effectivity of the microbial remediation of polyfilm effluent. Toxicity reduction of effluent was confirmed again by fish and pot assay, thus confirming that the treated effluent can be used for irrigation purposes. Finally, results indicated that the developed microbial consortium can be employed in ready-to-use form for the treatment of polyfilm industrial effluent by end users. © Springer Science+Business Media B.V. 2011.

Different samples of ZnS nanoparticals were synthesized by chemical co-precipitation method at room temperature using zincsulphate as zinc source and sodium suiphide as sulphur source. Structural properties of synthesized ZnS nanoparticles were studied by X-ray diffraction pattern (XRD) while optical properties were examined by UV-Visible absorption spectroscopy. XRD pattern showed the as synthesized ZnS nanoparticles have cubic zinc blended structure with 2.0-2.87 nm average crystallite size and lattice constant a=5.829 A°. UV-Visible absorption spectrum showed the band gap energy of the ZnS nanoparticala corresponding to absorption edge are found in the range of 2.63eV-3.87eV, which shows increase in band gap with the decrease of crystallite size ot the nanoparticles.

The drinking, dams and rivers water in the Beed district of Maharashtra, India area has been studied in three different seasons. The bacterial parameters like Total aerobic Heterotrophic Bacteria (THB), Total Coliform Count (TCC) and Faecal Coliform Count (FCC) have been monitored. In water samples from all the sites, bacterial count exceeded the recommended permissible level of WHO. The TCC and FCC also crossed the permissible limits prescribed by BIS. Pathogenic bacteria were isolated from the water samples. Introduction of sewage into the surface water was the main reason for the bacterial contamination. Various techniques for this destruction/removal of pathogenic bacteria are therefore advisable before consumption. © 2011 Sayed Rizwan A, et al. Source

Lip prints can provide vital information that may be useful for the purposes of forensic investigations. The current study was undertaken with the aims of determining the distribution and predominant lip-print patterns in a Central Indian (Marathi) population and evaluating whether any sex differences exist. The study subjects were 400 healthy consenting volunteers – 200 males and 200 females – aged 18–25 years, from the Marathi community. A simpler and more convenient method of data collection – digital photography – was used. The central (most motile) 1 cm2 portion of both upper and lower lips was analysed digitally. As per Suzuki and Tsuchihashi’s classification, overall, Type IV (27.5%) and Type III (6.25%) were found to be the most and least prevalent patterns, respectively. The Type II (32%) lip-print pattern was found to be most predominant in males, while Type IV (32.5%) was found to be most commonly occurring in females. Statistically significant differences (p <.01) were observed between lip-print pattern types in males and females. © 2015, © The Author(s) 2015. Source

On crime scenes, whole set of the ten digit fingerprints are rarely found and usually chance prints in the form of single digit fingerprint are encountered. Determination of hand (Right or left) can be of vital importance to reduce the burden on the investigator and may thereby aid in fixation of absolute identity of the donor. In the present investigation, 500 randomly selected and bilateral rolled fingerprints of 250 healthy, consenting adult subjects of a central Indian (Marathi) population with whorl patterns were examined to determine the hand. It was found that by studying various parameters like; slope of apex ridges (towards right, left or absent), rotation of innermost ridges (either clockwise, anti-clockwise or absent), angle formed at both sides of core, position of the perpendicular bisector on the delta line (with respect to core), ridge tracing (outer, inner or meeting), higher ridge count, angle between deltas and core (at deltas), direction of the pattern (tilting/inclination) and distance between the deltas & the core; it is possible to successfully determine the hand of the print. Applying chi-square test, the results were found to be statistically significant at p < 0.01 levels. © 2015 Elsevier Ltd and Faculty of Forensic and Legal Medicine. All rights reserved. Source
