Geochemistry of mafic dykes in part of Chotanagpur gneissic complex: petrogenetic and tectonic implications

Chotanagpur Gneissic Complex basement rocks of the Eastern Indian shield has been dissected by numerous mafic dykes, now occurring as amphibolitic dykes and gneissic amphibolites. These dykes are subalkaline, ranging in composition from basalt through basaltic-andesite to andesite. These rocks have enriched incompatible trace element patterns. These are particularly enriched in light rare earth elements (LREE) and large ion lithophile elements (LILE) with depleted high field strength elements (HFSE; Nb, P, Ti) characterisitcs (i). Negative Sr anomaly is conspicuous. Nb/La and Nb/Ce ratios of the dykes are lower compared to the primitive mantle but these values are closer to average crustal values. Incompatible trace element data suggest enriched source characteristics and influence of crustal contamination in their genesis. Trace element ratios such as Gd/Yb of these dykes indicate at least two different sources. They probably represent Precambrian continental rifting in this region

ISOLATION, BIOCHEMICAL CHARACTERIZATION AND MOLECULAR IDENTIFICATION OF ARSENIC RESISTANT BACTERIA ISOLATED FROM CONTAMINATED SITES OF UTTAR PRADESH, INDIA

Heavy metals are responsible to create toxicity in environment and these causes serious challenge worldwide. Arsenic is a heavy metal that is non-essential but toxic to all living beings. Arsenic has always been under emerging issue due to its toxicity in living beings including human and animals. Arsenic (As) is a toxic pollutant released into the environment either by natural phenomena or anthropogenic activities. Arsenic is known as carcinogenic element that can harm not only human health but, plant and bacteria as well. Pesticides are the major source for accumulation of As in the agricultural soils. Currently available bioremediation techniques have major disadvantages such as secondary environmental pollution and are less cost effective. Therefore, the present study was aimed to isolate arsenic resistant bacteria from terrestrial environment Bahraich, Uttar Pradesh, India for their potential applications in bioremediation strategies. Total thirty eight isolated arsenic-resistant bacteria were isolated, in which three bacterial isolates BBAU/LP3, BBAU/MMM1, and BBAU/MMM5 were taken for further studies due to their higher resistance ability to As and two isolates BBAU/LP3 and BBAU/MMM1 taken for molecular identification. The 16S rRNA gene sequence of the isolate BBAU/LP3 belongs to the genera Bacillus infantis and BBAU/MMM1 belongs to the genera Bacillus litoralis. The results revealed that our isolates BBAU/LP3 and BBAU/MMM1 encoded arsenite oxidizing gene and arsenate reducing gene respectively that will be useful for the development of efficient bioremediation strategies in the detoxification of arsenic from polluted environments

A novel GIS based seismic hazard assessment in Odisha, India

© 2018 Proceedings - 39th Asian Conference on Remote Sensing: Remote Sensing Enabling Prosperity, ACRS 2018 This research was conducted to analyse and estimate the PGA (Peak Ground Acceleration) and seismic amplification of Odisha state in India by using earthquake events recorded by USGS (US geological survey) of the region from the year 1950 to 2015. The analysis also includes for an approximately a range of 300 km from every side of state. Many attempts have been proposed to investigate the PGA in this region during the last decades. Therefore, it was a requirement to implement various methods using some recent viewpoints and methodological approaches. Furthermore, research approaches on seismic hazard analysis need to be updated for currently experienced seismic events. Therefore, the objectives of this research focusing; 1) to ensemble various attributes of seismic events for graphical investigation and, 2) to prepare hazard maps using PGA based on a distinctive GIS approach. Our results clearly showed that the region of Odisha is seismically active and there exists the hazard of ground shaking. It also provides a very accurate evaluation of seismic hazards including the seismic waves that influences surface of the ground based on the amplification map. These findings can be considered for the rapid improvement in earthquake research during recent decades that attempts to study seismic hazards and risks in Odisha

Design and Construction Aspects of Mini Coal Flotation Plant

Due to recent economic liberalisation policy of Govt. of India, it is expected that core industries like steel, cement, etc. will get more attention to foreign investment and technology and the new industries will come up along with large scale modernisation of existing industries. These user industries will require good quality low ash coking coal to fulfil its needs. The existing washeries of CIL are not in a condition to meet such specific requ-irement of these industries. Further, fine coal circuit of these washeries are not efficient resulting in discharge of Slurry having ash ranging between 30-40% which can not be used as such by, metallurgical and foundry industries. Moreover, discharges of slurry from washeries are poll-uting adjoining areas including nearby rivers. To overcome these problems scientists of Central Fuel Research Institute,Dhanbad have taken challenging init-iative and developed a novel close circuit process to treat these .slurry to produce low ash coal. The process is adopted by some private entrepreneurs and constructed small plants based upon the technology developed by CFRI. Three such plants have already been set up and are under operation with f ill efficiency.The present paper attempts to highlight the process, construction aspects and advantages of this type of Mini fine coal benefrcicttion plants which are producing love ash coking coal for use in the metallurgical industries

Analytical study of training needs of olive growers in various subject matter areas of olive cultivation in Uri Block of district Baramulla, J&K, India

The main purpose of this study was to know the training needs of olive growers in different subject matter areas of olive cultivation undertaken in Uri block of district Baramulla of Jammu and Kashmir State. A sample size of 150 respondents was randomly selected from 5 villages and from each village 30 farmers were selected randomly. It was observed during the study that majority of farmers require training and with emphasis on latest transfer of technology in establishing olive farm, procurement of root stocks of improved varieties, soil management,proper spacing and planting, manures and fertilizers, irrigation and drainage, insect-pests and diseases, harvesting and marketing, etc. The area of insect-pests and diseases require high training need followed by soil management, selection of varieties, manures and fertilizers, harvesting and marketing, irrigation and drainage, establishing olive farm and procurement of root-stocks of improved varieties. Therefore, the study has highlighted the need for restructuring the training programme to benefit the olive growers in the region. Such an approach would boost production and generate additional income for the orchardists
