^57Fe Mossbauer spectroscopic study was carried out on the organic rich sedimentary samples collected at different depth intervals from newly drilled test well Chinnewala Tibba-1（CT-1） located in Jaisalmer Petroliferous basin India. It is found that iron is mainly distributed in high spin Fe^3＋and Fe^2＋ state in clay minerals. The plot of Fe^2＋/（Fe^2＋＋ Fe^3＋） indicates the presence of poor redox conditions in the *** obtained are also compared with those already reported in the literature. This comparison shows that there may exist a correlation between prospecting of the basin, the redox environment in sediments and the nature of iron bearing minerals distributed in the sedimentary sequence.

Catalytic Cracking of Waste Polypropylene in a Nitrogen Fluidized Bed Reactor

引用

Journal of Geoscience and Environment Protection 2016年第4期4卷 20-25页

作者： Anil Vyas Suresh Kumar Singh Komal sharma Sukhwant Singh Chemical Engineering Department Jai Narain Vyas University Jodhpur India Civil Engineering Department Jai Narain Vyas University Jodhpur India Chemical Engineering Department MNIT Jaipur India

Polypropylene (PP) is rated first as volume leader in the plastic sector. Its non-biodegradable property poses serious environmental problem in case of disposal. The catalytic cracking of PP was performed with various catalysts i.e. ZSM-5, Zeolite, RB and SPS. The cracking was observed under different feed to catalyst ratio i.e. 1:1 to 5:1. The fluidized bed reactor was fabricated with arrangement to measure the temperature ranging from 100。C to 800。C. The effective of feed to catalyst ratio was found 3:1 at a temperature range of 420。C - 510。C and catalyst ZSM-5 gives maximum liquid conversion of waste PP. Conversion of PP to liquid fuel will not only resolve the problem of disposal of waste polypropylene plastic but also give a value aided product.

Meiotic Studies in <i>Withania somnifera</i>(L.) Dunal.: A Threatened Medicinal Herb of Indian Thar Desert

引用

American Journal of Plant Sciences 2012年第2期3卷 185-189页

作者： Hardev Ram Arun Kumar Santosh Kumar sharma Archana Ojha Satyawada Rama Rao Cytogenetics and Molecular Biology Laboratory Department of Botany Jai Narain Vyas University Jodhpur India. Department of Biotechnology and Bioinformatics North-Eastern Hill University Shillong India. Directorate of Rapeseed-Mustard Research Indian Council of Agriculture Research Bharatpur India.

Withania somnifera recently categorized as threatened plant of Rajasthan and known for its high medicinal value has been studied for existing genetic variations in four accessions collected from four different locations. From the present studies it is apparent that the gametic number of W. somnifera is n = 24 and 2n = 48. From the combined information generated by present author and earlier workers, it is tentatively believed that W. somnifera might be of allopolyploid origin with basic number of x = 12. In this case also precocious separation of rod bivalents but not structural hetrozygosity might be the reason for occurrence of univalents. From the detailed meiotic analysis, it is concluded that the species diversification is brought out by polyploidy in W. somnifera. Multidisciplinary approach for genome diagnostics with use of various marker systems might through more light on existing intra-specific genetic variation in W. somnifera.
