Subject: Arsenic and other metals in the groundwater samples of Ranchi city, Jharkhand, India
Keywords: Arsenic, groundwater, land use, metal contamination.
Abstract: This study was aimed to monitor and quantify the metals present in the groundwater of Ranchi city, state capital of Jharkhand, India. Samples were collected from 44 locations during three seasons. The results show that arsenic concentration ranged from 0 to 0.2 and 0 to 0.015 mg/l in monsoon and pre-monsoon seasons respectively, but was below detection limit in the post-monsoon season. Manganese varied from 0 to 4.199, Nickel from0 to 0.77, Selenium from 0 to 0.14, and Fe varied from 0 to 0.047 mg.l. Presence of toxic metals, especially arsenic, above acceptable limits is alarming and needs immediate attention.

Subject: Statistical an analytical study of guided abstractive text summarization
Keywords: Abstractive and extractive text summarizations, information extraction, language parsing and understanding, template selection, template-based generation.
Abstract: The process of creating condensed version of given text document by collecting only the important information in it is called abstractive summarization. This involves structuring the information into sentences which are simple and easy to understand. This communication presents the analytical study of the process that generates abstractive summary using unified model with attribute based information extraction (IE) rules and class based templates. Classification of the document into several categories is achieved by term frequency/inverse document frequency (TF/IDF) rules. To generate the information intensive summaries, we use templates for sentence generation. The IE rules are designed to address the complexities involved in Indian regional languages. This paper statistically analyses the adaptation of the methodology over multiple Indian languages and many document categories. Comparisons between abstractive and extractive summaries are also presented.

Subject: Studies on the maintenance of ' self-sustained ' mosquito vector population in Vaigai river, South India.
Keywords: Animal husbandry, aquatic vegetation, larval density, sewage inlets, water quality.
Abstract: Study of mosquito species diversity and its relationship with ecosystems is essential to understand disease epidemiology and to develop control measures of vector populations in human-dominated ecosystems. In the present study, the structure and composition of immature mosquito population and associated ecological parameters water analysed in three different ecosystems (urban, semi-urban and rural) along Vaigai river, Madurai, Tamil Nadu, India. Average larval density was higher in urban than the semi-urban and rural sites during the study period. In 2012-13, immature mosquito diversity was higher in rural site during pre-monsoon and monsoon seasons, whereas mosquito larval diversity was greater in semi-urban site during the post-monsoon season. In 2013-14, mosquito larval diversity was found to be high in semi-urban site during monsoon and post-monsoon seasons. Culicine species dominated the urban areas, while Anopheline species dominated the urban areas, while Anopheline species dominated the rural and semi-urban sites during the study period. Among the mosquito species, Culex tritaeniorhynchus, Cx. geldius, Cx. vishnuvi, Cx. quinquefasciatus, Cx. bitaeniorhynchus, Anopheles subpictus and An. culcifacies were prevalent throughout year. Filamentous algal-dominated sites showed a higher number of mosquito species (23 species) than other hydrophytes-dominated sites. As a result, the highest turbidity level was recorded in the urban site followed by semi-urban and rural sites. The present study shows that the immature mosquito population is maintained with the help of ecological parameters in all the study sites through the year. Therefore, it is essential to take steps to eradicate the mosquito vectors from the Vaigai river basin to avoid disease outbreak in the region.

Subject: Drosophila as a model for mosquito
Keywords: Drosophila, host-seeking behaviour, mosquito, olfactory signals.
Abstract: Olfactory cue dependence of insects such as mosquitoes is beneficial in understanding insect behaviour during host seeking. Understanding of the host-seeking behaviour, particularly, the olfactory process involved in it at molecular level is likely to provide new means of controlling insects. A number of studies have shown Drosophila as a successful model system to decipher and delineate the role of olfactory genes. Such studies can be extended to understand the host-seeking behaviour of mosquitoes. We discuss recent progress in this area and an emerging new approach that can utilize Drosophila, genetically modified to carry mosquito receptors, in identifying compounds that can be subsequently used to control mosquitoes.

Abstract: Higher breeding ratio, high thermal conductivity, shorter doubling time and high plutonium production make metallic fuels a viable solution compared to oxide/nitride/carbide/silicide/ fuels for cost-effective commissioning of many power reactors. Metallic fuels lend themselves to compact and simplified reprocessing and re-fabrication technologies, a key feature in a novel concept for the deployment of fast reactors. Satisfactory physical and technical characteristics of fuel roads with metallic fuel have been demonstrated at high burn-ups, and comparatively easy reprocessing o spent fuel using the pyro-metallurgical method makes this fuel relevant in fast reactors development. The present wok is complemented with a scientometric study.

Subject: Standardization of tapping techniques of gum extraction in Lannea coromendelica
Keywords: Natural gums, Tapping, Borehole method, Ethephon, Lannea coromendelia
Abstract: Gum collection from trees is important livelihood sources for local dwellers in drought prone Rajasthan and its surroundings areas. The industrial application of natural gums has been expanded tremendously in recent years. Traditional method of gum tapping is crude and unscientific; the deep incision, untimely extraction and high concentration of chemicals in gum have affected the Lannea coromendelica species in its natural habitat. The studies were conducted for two years to standardize the tapping methods, tapping seasons, chemical concentration on trees having dbh>40 cm from natural stands. For obtaining the maximum gums from these species, different tapping techniques have been applied to enhance the gum production. In bore hole tapping method, a hole of 5 cm is made on tree stem yielding higher gum yield when injected with ethephon concentration of 300 mg/ml and 400 mg/ml in Lannea cormomendelica. The maximum gum production was obtained in borehole tapping method in minimum was procured from V-shaped tapping method. Ethephon has proved better extraction chemical over the sulphuric acid. Ethephon concentration of 300 mg/ml showed the highest gum production of 144.2 grams/tree. However, lower concentration of sulphuric acid did not show significant results Ethephon induces gummosis without affecting the health of tree. Tapping seasons also significantly affect the gum production, the highest gum production of 66.94 gram/tree obtained in April-June tapping season.

Abstract: Studies were undertaken to establish the cause of decline/drying/wilting in bael plants from 2008 to2014 which included different factors viz., nutritional, physiological, epidemiological, entomological and pathological. Perusal of pooled data of seven years showed that the organic carbon content of soils was low and ranged from 0.12 to 0.20 and 0.11 to 0.19 percent in soil of diseased and healthy plants, respectively. In general, it decreased with increasing soil depths. The available phosphorus content varied from 6.67 to 9.06 kg ha-1 in soils of healthy plants and 6.67 to 8.63 kg ha-1 in soil of diseased plant and was low at all soil depths. The available phosphorus content varied from 6.67 to 9.06 kg ha-1 in soils of healthy plants and 6.67 to 8.63 kg ha-1 in soil of diseased plant and was low at all soil depths. The available copper, manganese and boron were sufficient in all depths of both soils collected from the rhizosphere of healthy and diseased plants. The DTPA extractable zinc was 0.89 ppm in soil of diseased plants and 0.76 ppm in soils of healthy plants at 0-30 cm depth and decreased with soil depth however it was in deficient range at 45-60 cm, 60-90 cm and 90-120 cm depth in soil of diseased plants. The DTPA extractable Fe was found to be deficient in both the samples of soils at 60-90 cm depth. The N, P and K content of healthy bael leaves were 1.20, 0.14 and 1.19 percent where as it was 0.90, 0.08 and1.02 per cent in leaves of diseased plants. The Zn, Cu, Mn, Fe and B content of leaves of healthy and diseased plants were in sufficient range, however, these content were higher in healthy leaves as compared to diseased leaves. The highest drying in bael trees was recording during May-June and September-October beyond which incidence reduced gradually. Root bores, Acanthophorus rugiceps (2-3/plant of 115 mm length) were observed during 2011, 2012 and 2014 at a depth of 2 to 3 ft indicating possible association with the drying of plants. Gliocladium catenulatum, G.penicillioides, Rhizoctonia bataticola and Fusarium solani were isolated from roots of diseased plants an pathogenicity with regard to F.solani was proved.

Abstract: In the present study, an attempt was made to study the diversity status of Arbuscular Mycorrhizal (AM) fungi in selected non-timber yielding species in dry tropical forests of Central India. It was found Glomus spp. was the most frequently available AM fungal species. Maximum percent root colonization was observed in Bachanania lanzan (46.7%) and Madhuca longifolia (40%) and first time reported for the presence AM colonization (vesicles) in these tree species. Colonization results show that all the sites have good diversity of AM fungi, which is a precursor for natural regeneration and seedling survival. Spore numbers showed strongly negative correlation with sand content and electrical conductivity, and a proliferation pattern with an increase in clay content. No clear correlation was seen between spore numbers and organic content, nitrogen and potassium.

Keywords: Colony forming units, Inoculants, Shelf life
Abstract: Biological control is most applicable method for controlling plant diseases. The term applies the use of microbial antagonist to suppress disease as well as specific pathogen. For controlling the disease, biocontrol agent must be ecologically fit to survive, become well established and function within a particular condition of the ecosystem. In general, organism introduced into an established system does not persist for a long time. The introducing agent must have an acceptable shelf life. Major considerations in developing a viable biocontrol product are the production, formulation and delivery of propagules that are viable and effective. Five solid carriers viz.groundnut shell saw dust, bagasse, paddy straw and soil were used for the preparation of carrier based inoculums of Trichoderma and Rhizobium species screened previously against wilt disease pathogen Fusarium salani. Physical properties of the carriers were also measured which were also measured which were found optimum for inoculums growth. Bagasse and saw dust was proved best among all the five carriers by maintaining high population density of inoculants among the year. Groundnut shell and paddy straw was considered as moderate carriers in comparison to bagasse and saw dust while soil was unable to maintain appropriate viable cells of the inoculants all over the year.

Subject: Effect of Biofertilizers and inorganic fertilizers on nitrogen and phosphorus uptake in Acacia Nilotica (L).Willd.Ex.Del.Seedlings.
Keywords: Acacia nilotica, A.M fungi, Rhizobium, Nitrogen, Phosphorus, Nutrient uptake
Abstract: The present study was conducted to generate information on effect of inorganic and biofertilizers, alone and in combination, on nutrient uptake in Acacia nilotica seedlings. The treatments comprised of all possible thirty-six combinations of three levels of nitrogen (0, 30 and 60 kg N ha-1) three levels of phosphorus (0, 75 and 150 kg P2O5 ha-1) and four biofertilizers levels (Control biofertilizer, AM fungi, Rhizobium and AM fungi +Rhizobium).The experiment was established in factorial split plot design with nine combination of N and P in the main-plot and three bio-fertilizer levels and one control in the sub plots with three replications. Inoculation with AM fungi and Rhizobium, singly and dually resulted in nitrogen and phosphorus uptake in shoot and root as compared to uninoculated control. Among different doses of nitrogen and phosphorus, when applied singly, 30 kg N and 75 kg P2O5 ha-1 resulted in maximum N and P uptake by roots and shoots. Dual inoculation of AM fungi and Rhizobium supplemented with 30 kg N and 75 kg P2O5 ha-1 significantly increased nitrogen and phosphorus uptake by roots and shoot.

Subject: Resource conservation an economic utilization of Yamuna Ravine land through Bamboo (Dendrocalmus strictus) Plantation.
Keywords: Biomass, Socioeconomic profile, Dependency, Altitude, Western Himalaya
Abstract: Biomass has been the principal component of domestic energy throughout the Indian Himalayan region. The present study, carried out in two altitudinal zones, explored the forest resource use pattern in relation to the socio economic status of the denizens in a part of Western Himalaya, India. Structured an pretested questionnaires were used to interview approximately 30% of the total households in each village (a total of 143 in 9 villages).The average cultivated land per family was less than 1 ha (0.85).In sub tropical and temperate zones, the average fuelwood an fodder consumption (kg/day/household) was found to be 14.93 and 63.80 and 13.16 and 60.42 respectively. Statistical analysis showed significant variation of fuelwood and fodder consumption in the two altitudinal zones (p<0.000, t-test; n=143 and df=142).Alternative fuels (kerosene and LPG) are used occasionally. More than 70 % of biomass is extracted from the forests and a total of 30 tree species are frequently lopped for this purpose. The pressure exterted by human and bovine populations, coupled with unsustainable management policies has resulted in the destruction of forest cover and ecological degradation. Support and active participation of local people is mandatory for conservation of these forests.
