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.

Suicide, a major problem worldwide, continues to be a criminal offence in most of the developing countries of the world, including India. This paper retrospectively examines the latest trends and the relevant determinants of the suicidal deaths in one of the most important city of central India- Nagpur of Maharashtra state, carried out for a period of 5 years i.e. 2009-2013. Total 2036 cases were analyzed. An alarmingly increasing trend in the rate of suicides has been observed in the region, which increased from 16% to 22.68% during the study period. The male to female suicide ratio was found to be 2.50:1. The rate of suicidal deaths ranged from 15.34 to 21.74 per 100,000 populations. Hanging was found to be the most preferred mean adopted for suicide by males (54.77%) and females (47.65%), while, Family problems was the most common cause of suicide among both male (38.25%) and female (52.65%). The Suicides were concentrated in the age group of 30-44 years for males (35.76%), while in the age group of 15-29 years for females (51.75%). The prevalence was higher among the people who were married, being as high as 1099 (66.73%) males and 372 (56.45%) females. Highest trend has been found among the people with matriculate/secondary education level. The males with job in private sector accounted for 1007 suicides (61.14%) and 434 (65.86%) females in the category of housewives (non-working, homemakers) committed the same. © 2014 Elsevier Ltd and Faculty of Forensic and Legal Medicine.

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.

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.

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 distribution of fingerprint patterns has been found to be varying amongst the different population groups across the globe. Hence, this knowledge becomes crucially important in forensic investigations. The present study was conducted on 480 healthy and consenting Muslim individuals (240 males and 240 females) from Maharashtra State in India. The aims were to determine the frequency distribution of various fingerprint patterns; establish the most and least predominant patterns; and to find out whether any statistically significant gender differences exist. Rolled finger impressions taken in duplicate on fingerprint identification slips were analysed twice by both the authors independently (so as to eliminate any error in the classification due to inter-observer and intra-observer variations). The distribution of patterns was found to be in the following order: ulnar loop (max) > spiral whorl > twinned loop > central pocket loop > concentric whorl > tented arch > plain arch > radial loop > lateral pocket > accidental (min). Applying the t-test to the obtained results, gender differences were found to be statistically insignificant (p > 0.05). Various dermatoglyphic indices (Pattern Intensity Index, Dankmeijer's Index and Furuhata's Index) were calculated and compared to the available data in various other ethnic groups and populations. A new 'Combined Pattern Index', is proposed. © 2014.

Background: Identification of sex plays a vital role in forensic and medico legal investigations. Fingerprints are considered to be the most precise and reliable indicators for personal and gender identification. Objectives: The objective of this study was to determine any significant difference in the thumbprint ridge density of males and females in a central Indian (Marathi) population to enable the determination of gender. Methods and materials: The study was conducted on 200 subjects (100 males and 100 females) in the age group of 18-30. years. Ridge densities on the right- and left-hand thumbprints were determined using a newly designed layout and analysed statistically. Results: The results showed that females tend to have a higher thumbprint ridge density in both the areas examined, individually and combined. Applying the t-test, the differences in the ridge densities of males and females at LoC (Left of Centre), RoC (Right of Centre) and Combined (LoC. +. RoC) were found to be statistically significant at p<. 0.01 levels, proving the association between gender and fingerprint ridge density. Probability densities for men and women derived from the frequency distribution (at LoC, RoC and Combined) were used to calculate the likelihood ratio and posterior probabilities of gender designation for the given ridge count for subjects using Baye's theorem. Conclusion: It was concluded that differences in the thumb ridge density can be used as an important tool for the determination of gender in cases where partial thumbprints are encountered as evidence either at the crime scene or on any document(s) of forensic significance. © 2014 .

Latent fingerprints are subject to easy damage and destruction owing to their fragile nature. Powder dusting is the easiest and fastest of the methods used for latent fingerprint development (LFPD). In the present study, Robin® powder blue, a common household product (used as a post-wash whitening agent and popularly known in India as 'neel') which is user friendly, less expensive, non toxic, non hazardous, environment friendly, simple and easily available substitute to the commercially available and costlier powders, has been used for LFPD. The powder was tested on twenty-four strategically chosen surfaces, keeping in mind the high frequency at which they are commonly encountered on various crime scenes. It was shown that this powder gives very good results, even on most of the intricate and multi-colored surfaces tested. © 2015.

Lip prints are very useful in forensic investigations. The objective of this study is to determine predominant lip print pattern found among a central Indian population, to evaluate whether any sex difference exists and to study the permanence of the pattern over a 6. month duration. This study included 200 healthy adult subjects comprising of 100 males and 100 females in the age group of 18-25. years. A convenient and easier method of data collection i.e., digital photography was used instead of the traditional lipstick methods. Lip prints were then divided into four quadrants and recognized as per Suzuki and Tsuchihashi's classification.Type I (30.63%) was found to be most predominant overall in the Marathi population. Type I (29.75%) and Type III (35.75%) were found most prevalent in males and females respectively. Applying the Chi-Square test, statistically significant differences (p <. 0.05) were observed between male and female lip print patterns in each of the quadrants individually and all quadrants taken together. The lip print patterns remained stable over a period of six-months. Being stable and with significant sex differences, lip prints can be effectively used as an important tool in forensic investigations for individualization as well as identification of sex of the donor, thus, narrowing down the scope of investigation to almost half. © 2015 The Authors.
