For cubic SrMO3 perovskites (M = Ti & Zr) lattice parameter and bulk modulus have been computed using the first principle approach within Density functional theory. By local density approximation (LDA) method, the results have been calculated. It is found that the calculated lattice parameter and bulk modulus for all transition metal oxides are in good agreement with the available experimental data. All these calculations have been carried out using ABINIT computer code. © 2013 American Institute of Physics.

The study deals with the cultivation of Pleurotus citrinopileatus on the sludge of handmade paper and cardboard industrial waste. These industrial wastes are rich in cellulosic and lignocellulosic pulp residues which can be used as a novel substrate for the cultivation of mushrooms. These industrial wastes were used alone and in combination with wheat straw for the cultivation of mushroom. To assess suitability of mushroom (carpophores) for consumption, cultivated carpophores analyzed for nutritional content and genotoxicity by standard AOAC methods and Ames test, respectively. A significant decrease in the biological efficiency, protein and fat of the said mushroom (only in the mentioned sludges) was observed, nevertheless, carpophores possessed a high amount of frameshift mutagens and thus being non-consumable. Contrastingly, the carpophores that were developed on the absolute equal combination of industrial sludge and wheat straw were found to possess high biological efficiency, protein, carbohydrate and fat content whereas decrease frameshift mutagens. On boiling the aqueous extract of mushroom, a further decrease in frameshift mutagens was observed. In conclusion, the use of combination of sludge and wheat straw not only increased the biological efficiency but also provided less mutagenic carpophores and mutagenicity of these carpophores further reduced on boiling. © 2012 Elsevier B.V.

The possibility of utilizing handmade paper and cardboard industrial sludges in the production of edible mushrooms involves risk of introducing toxic substances into the human food chain. Therefore, in the present study, genotoxic assessment of P. florida (Pleurotus florida) cultivated on these industrial sludges and their combination with wheat straw was done by Ames test using Salmonella typhimurium TA 98 and TA100. Interestingly, P. florida carpophores, cultivated on wheat straw did not show either frameshift or basepair mutagenicity as revealed by mutagenicity ratio (<2) and mean number of revertants which was found to be 81.3 and 93.4 revertants per plate in the absence of S9 mix. However, this number was found to be increased to 112.1 and 226.3 revertants with S9 mix. P. florida cultivated on waste and its combination showed increase in number of revertants (123.4-170.1 revertants with TA 100 and 79.5-84.1 revertants with TA 98) in the absence of S9 mix over control. Further, increase in number of revertants (229.0-247.3 with TA 100 and 100.3-129.1 with TA 98) was observed on adding S9 mix with both strains S. typhymurium but still mutagenicity ratio was found to be below 2. Hence, these mushrooms were not found to be genotoxic. This mushroom cultivation technique, will not only provide proteinaceous food but also help in reducing industrial wastes. Besides, these can serve as very good source of income for the poor workers working in these industries that can collect the waste from the industries and use it for P. florida cultivation. ©IIOAB-India.

Health care waste includes all the waste generated by health care establishments, research facilities, and laboratories. This constitutes a variety of chemical substances, such as pharmaceuticals, radionuclides, solvents, and disinfectants. Recently, scientists and environmentalists have discovered that wastewater produced by hospitals possesses toxic properties due to various toxic chemicals and pharmaceuticals capable of causing environmental impacts and even lethal effects to organisms in aquatic ecosystems. Many of these compounds resist normal wastewater treatment and end up in surface waters. Besides aquatic organisms, humans can be exposed through drinking water produced from contaminated surface water. Indeed, some of the substances found in wastewaters are genotoxic and are suspected to be potential contributors to certain cancers. The aim of this study was to evaluate the genotoxic and cytotoxic potential of wastewaters from two hospitals and three clinical diagnostic centers located in Jaipur (Rajasthan State), India using the prokaryotic Salmonella mutagenicity assay (Ames assay) and the eukaryotic Saccharomyces cerevisiae respiration inhibition assay. In the Ames assay, untreated wastewaters from both of the health care sectors resulted in significantly increased numbers of revertant colonies up to 1,000-4,050 as measured by the Salmonella typhimurium TA98 and TA100 strains (with and without metabolic activation) after exposure to undiluted samples, which indicated the highly genotoxic nature of these wastewaters. Furthermore, both hospital and diagnostic samples were found to be highly cytotoxic. Effective concentrations at which 20 % (EC20) and 50 % (EC50) inhibition of the respiration rate of the cells occurred ranged between ∼0.00 and 0.52 % and between 0.005 and 41.30 % (calculated with the help of the MS excel software XLSTAT 2012.1.01; Addinsoft), respectively, as determined by the S. cerevisiae assay. The results indicated that hospital wastewaters contain genotoxic and cytotoxic components. In addition, diagnostic centers also represent small but significant sources of genotoxic and cytotoxic wastes. © 2013 Springer-Verlag Berlin Heidelberg.

Objective Despite public health campaigns based on Fe and folic acid supplements, Fe-deficiency anaemia remains highly prevalent among women in India. We investigated leaf concentrate as an alternative to Fe and folic acid supplements for treating anaemia in adolescent girls.Design Randomised controlled two-arm trial over 3 months: one group received daily Fe and folic acid (IFA; 60 mg Fe, 500 μg folic acid); the other daily leaf concentrate (LC; 5 mg Fe, 13 μg folic acid). Hb concentration, mean cell volume, serum Fe, serum ferritin and total Fe-binding capacity were measured pre- and post-intervention.Setting Jaipur, India.Subjects One hundred and two adolescent girls aged 14-18 years.Results Of the 102 girls randomized to the two arms of the trial, four (39 %) were severely anaemic (Hb < 7 g/dl), twenty-eight (27·5 %) were moderately anaemic (Hb >7 g/dl, <10 g/dl) and seventy (686 %) were mildly anaemic (Hb 10 >g/dl, <12 g/dl). In the IFA group, eleven girls (20·4 %) withdrew due to side-effects, compared with one girl (2·1 %) in the LC group (P = 0·005). Total losses to follow-up were 14/54 in the IFA group and 2/48 in the LC group. At the end of the trial, none of the eighty-six remaining girls were severely anaemic, nine (10·5 %) were moderately anaemic and twenty-six (30·2 %) were mildly anaemic; fifty-one (59·3 %) had normal Hb levels (>12 g/dl). After adjustment for baseline values, LC was as effective as IFA in improving serum Fe parameters and treating anaemia.Conclusions Leaf concentrate is an effective, and more palatable, alternative to Fe and folic acid supplements for treating anaemia in adolescent girls. © 2009 The Authors.

Persistent organochlorine residues such as hexachlorohexane isomers (HCHs), chlorocyclodienes and DDT group (DDTs) were determined in fecal matter/guano of common wild pigeon (Columba livia) collected from rural, urban and suburban areas in Jaipur. Chlorinated contamination pattern varied largely among the three areas. Samples collected from rural areas of Jaipur contained greater concentrations of endosulfan (1.17 μg/g dry wt) than those of urban and suburban areas. In contrast, fecal samples collected in suburban areas exhibited elevated levels of ∑HCH (0.95 μg/g dry wt) as compared with urban (0.46 μg/g dry wt) and rural areas (0.82 μg/g dry wt). Our study suggests that levels of organochlorine pesticide residues detected in avian guano are perhaps a reflection of the environmental status of the habitat. Thus avian guano may serve as a non-destructive biomonitoring tool for organic pollutants in environment. © 2012 Elsevier Ltd. All rights reserved.

Handmade paper and cardboard industries are involved in processing of cellulosic and ligno-cellulosic substances for making paper by hand or simple machinery. In the present study, solid sludge and effluent of both cardboard and handmade paper industries was collected for developing a mushroom cultivation technique to acheve zero waste discharges. Findings of present research work reveals that when 50% paper industries waste is used by mixing with 50% (w/w) wheat straw, significant increase (96.38%) in biological efficiency over control of wheat straw was observed. Further, cultivated basidiocarps showed normal morphology of stipe and pileus. Cross section of lamellae did not show any abnormalityin the attachmentofbasidiospores, hymenal trama and basidium. No toxicity was found when fruiting bodies were tested chemically. © Triveni Enterprises, Lucknow (India).

We integrated five indicator indices viz., wildlife distribution index (WDI), ecological value index (EVI), ecotourism attractivity index (EAI), environmental resiliency index (ERI), ecotourism diversity index (EDI) to identify and prioritize the potential ecotourism sites in West District of Sikkim state in India. The primary variables used for generating various indices were landform, elevation, land use/forest cover, vegetation diversity, density and endemism, wildlife (mainly birds and butterflies), tourism attraction features and the infrastructure facilities. Data and information from remote sensing and other sources were used. The analytical hierarchical process and geographic information system were effectively used for identification of the potential ecotourism sites (PES). © International Society for Tropical Ecology.

The textile and apparel industry of India which is one of the most globalizing industries in today's world is witnessing technological advancement in all the major areas. India is the world's second largest producer of textile and garments. Garment exports has totaled $1 0.1 7 billion in 2008-09, giving it an enviable share of 2.99 percent. Marks & Spencer in the UK have long had a powerful and formative influence upon the whole of its supply chain. Automation still has a key role to play, but it is now more concerned with enabling rapid adjustments of equipment from style to style, eliminating non-productive handling of fabrics and garments, and raising quality. CAD/CAM are the first area of impact of new generation clothing technology in advanced industrial countries and seems likely to repeat the success elsewhere. Advanced technologies thus play an indispensable part for the Indian garment manufacturing industry.

Many unconventional methods and techniques are tried in wet processing of textile material, very often to explore eco-friehdly, alternative methods. Plasma technique is poised to change the concept of textile wet processing. Plasma technology is a surface-sensitive method that allows selective modification in the nm-range. "Thus any ionized gas that is composed of nearly equal numbers of negative and positive ions is called plasma" The second significant benefit that plasma based textile manufacturing offer is development of new fabric treatment with a desired attribute that cannot be achieved by other means. Plasma modification of textiles saves large quantity of water, chemicals and electrical energy, which is made possible since the plasma process does not produce large volume of waste or toxic by products. It improves the surface property of textile material without changing the bulk properties. By introducing energy into a gas, quasi natural plasma can be generated consisting of natural particles, electrically charged particles and highly reactive radicals plasma processing methods have been explored in improving the preparatory process in spinning, fabric preparation, dyeing, and finishing of cotton, wool, silk and most of the man made fibers.
