      • Application of drum compost and vermicompost to improve soil health, growth, and yield parameters for tomato and cabbage plants

        Goswami, Linee,Nath, Anil,Sutradhar, Sweety,Bhattacharya, Satya Sundar,Kalamdhad, Ajay,Vellingiri, Kowsalya,Kim, Ki-Hyun Elsevier 2017 Journal of environmental management Vol.200 No.-

        <P>Utilization of different types of solid wastes through composting is important for environmental sustainability and restoring soil quality. Although drum composting is an efficient technology, the possibility of heavy metal contamination restricts its large-scale use. In this research, a field experiment was conducted to evaluate the impact of water hyacinth drum compost (DC) and traditional vermicompost (VC) on soil quality and crop growth in an agro-ecosystem cultivated intensively with tomato and cabbage as test crops. A substantial improvement in soil health was observed with respect to nutrient availability, physical stability, and microbial diversity due to the application of drum compost and traditional vermicompost. Moreover, soil organic carbon was enriched through increased humic and fulvic acid carbon. Interestingly, heavy metal contamination was less significant in vermicompost-treated soils than in those receiving the other treatments. The use of VC and DC in combination with recommended chemical fertilization effectively stimulated crop growth, yield, product quality, and storage longevity for both tomato and cabbage.

        Study of Mechanical, Optical, and Electrical Behaviors of Calcium Alginate/ Poly(vinyl alcohol)–Vanadium Pentoxide Bionanocomposite Films

        Anil Kumar Bajpai,Anjana Goswami,Jaya Bajpai,Benoy Kumar Sinha 한국고분자학회 2018 Macromolecular Research Vol.26 No.4

        Thin films of calcium alginate (CaAlg)/poly(vinyl alcohol) (PVA) and CaAlg/PVA-vanadium pentoxide (V2O5) bionanocomposites were synthesized by solution casting approach followed by impregnation of vanadium pentoxide and investigated for their structural, mechanical, optical, and electrical properties for possible use as cathode material in Li-ion batteries. The interaction of V2O5 nanoparticles with CaAlg/PVA film was investigated using Fourier transform infrared (FTIR) spectroscopy which suggested for strong interactions between V2O5 nanoparticles and CaAlg/PVA matrix film thus confirming successful impregnation of V2O5 into the matrix film. Crystalline nature of prepared samples was probed by X-ray diffraction (XRD) technique that indicated improvements in crystalline nature of the material. For evaluation of particle size and morphology, transmission electron microscopy (TEM) was also used. The roughness of the surfaces of bionanocomposite films was also determined by the atomic force microscopy (AFM) which showed an increase in morphological parameters upon impregnation of vanadium pentoxide nanoparticles into the polymer matrix. The thermal properties like glass transition temperature, crystalline point and crystalline melting point were determined by differential scanning calorimetry (DSC) technique. The results of tensile strength and microhardness measurements depicted that the prepared bionanocomposite films possessed good mechanical strength than the native polymer matrix. Significant enhancement in electrical conductivities was observed upon insertion of V2O5 into the native blend film.

        Prevalence of Irritable Bowel Syndrome: A Community Based Study From Northern India

        ( Govind K Makharia ),( Anil K Verma ),( Ritvik Amarchand ),( Anil Goswami ),( Prashant Singh ),( Abhishek Agnihotri ),( Faizul Suhail ),( Anand Krishnan ) 대한소화기기능성질환·운동학회(구 대한소화관운동학회) 2011 Journal of Neurogastroenterology and Motility (JNM Vol.17 No.1

        Background/Aims The prevalence of irritable bowel syndrome (IBS) varies from 4% to 20% in different Asian nations. Prevalence of IBS in native North Indian community is not known. Methods Between November 2008 to December 2009, we estimated the prevalence of IBS in a rural community of Ballabgarh block, located in Haryana state. A structured questionnaire based on Rome Ⅲ module was used to collect symptoms related to IBS from all the participants in a door to door survey. A Rome Ⅲ criterion was used for diagnosis of IBS. IBS was further classified based on predominance of symptoms as constipation predominant, diarrhea predominant, mixed and unspecified based on Rome Ⅲ module. Results There were 4,767 participants (mean age 34.6±10.8, males 50%). Overall, 555 (11.6%; 95% CI, 10.7-12.5) had constipation, 542 (11.4%; 95% CI, 10.5-12.3) diarrhea and 823 (17.3%; 95% CI, 16.2-18.4) abdominal pain. The overall prevalence of IBS was 4% (95% CI, 3.5-4.6). The prevalence of constipation predominant IBS was 0.3% (95% CI, 0.16-0.49), diarrhea predominant IBS 1.5% (95% CI, 1.18-1.90), mixed IBS 1.7% (95% CI, 1.35-2.11) and unsubtyped IBS 0.5% (95% CI, 0.32-0.75). The prevalence of IBS was significantly higher in females compared with males (4.8% vs 3.2%, P=0.008). However, there was no significant difference between males and females in the prevalence of different subtypes of IBS. The prevalence increased with age. Conclusions The prevalence of IBS in a North Indian community is 4%. IBS poses a significant burden on the rural adults. (J Neurogastroenterol Motil 2011;17:82-87)
