The present study was conducted by Directorate of Extension, SHIATS, Allahabad during 2015 and 2016 in the summer season with 20 frontline demonstrations on summer moong covering an area of 05 hectare in Bhadohi district of Uttar Pradesh to exhibit latest production technologies and compared it with farmer's practice. An attempt has also been made to know the productivity of front line demonstration and the adoption of latest production technologies by the 20 FLD farmers and 20 Non-FLD farmers. FLD farmers and non-FLD farmers were randomly selected from FLD villages. The results were compared between FLD plots and control plots. From the front line demonstrations, it was observed that the improved moong variety Samrat recorded the higher yield 6.82 q/ha and 7.39 q/ha compared to the farmers' practice variety 4.56 q/ha and 5.25 q/ha in the year 2015 and 2016, respectively. The increase in the demonstration yield over farmer's practices was 45.16%. The extension gap, technology gap and technology index were recorded 2.20 q/ha, 2.89 q/ha and 28.95%, respectively. The increment in yield of moong crop under frontline demonstrations was due to spreading of improved and latest technology viz. seed treatment with fungicide, seed inoculation with biofertilizers, recommended seed rate, yellow vein mosaic (YVM) resistant variety, line sowing, proper dose of fertilizers and plant protection measures. Improved technologies gave higher mean net return of j 15644.50 per hectare with a benefit cost ratio 1.77 as compared to farmers practice ( j 9111.00 per hectare benefit cost ratio 1.58).

The paper deals with the pesticide monocrotophos (0 - 600 ppm) induced changes in physiological and biochemical parameters related to growth and defense system in Azolla filiculoides. Monocrotophos treatment on fresh weight, dry weight, doubling time, chlorophyll, carotenoids, relative growth rate, lipid peroxidation, electrolyte leakage, proline accumulation and activities of superoxide dismutase and peroxidase were analyzed. Growth and photosynthetic pigments, i.e. chlorophyll and carotenoids were adversely affected by monocrotophos treatment and the inhibition was found to be dose dependent. Pesticide treatment with increasing doses accelerated the formation of reactive oxygen species, i.e. O - 2 and H 2O 2 in cells progressively, whereby an enhanced lipid peroxidation and electrolyte leakage was noticed in A. filiculoides. Proline accumulation also showed a similar trend. As a consequence of reactive oxygen species (ROS) generation in monocrotophos treated plants, the activity of superoxide dismutase (SOD) and peroxidase (POD) were enhanced considerably.

Biomass is a biological carbonaceous organic material and provides both the thermal energy and reduction for oxides; where as other non conventional sources of energy can meet our thermal need only. Biomass is the purest fuel consisting of very smaller quantity of ash materials. Hence, Biomass is an important source of energy and the most important fuel worldwide after coal, oil and natural gas. Bio-energy, in the form of biogas, which is derived from biomass, is expected to become one of the key energy resources for global sustainable development. The present work is an optimistic step towards energy and ecological problems facing the world. At present, the technique for power generation is co-firing (coal & biomass) has more attractive and cost-effective. Co-firing can play an important role in increasing the use of biomass in power generation and reducing greenhouse gas emissions. Biomass, co-firing offers several advantages, including lower capital costs, higher efficiency and improved economies of scale and lower electricity costs due to the larger size and the superior performance of modern coal power plants. In this paper, the non coking coal and biomass are mixed together for preparing briquettes of different ratio (coal: biomass = 93:07, 87:13, 83:17, 77:23) and to examine their energy values and power generation potential. © IAEME Publication.

This digital era has seen a tremendous growth in technology and we find ourselves amidst vast amounts of data that needs to be accessed and shared with people all over the World. A challenge is posed when data has to be transmitted secretly and securely. This paper presents a scheme for covert communication using data compression and the arithmetic division operation. The secret data is first compressed using a compression algorithm and then embedded into the edges of the cover image using an arithmetic division operation and various other logical operations. Experimental results indicate that the proposed technique provides a stego image of good visual quality. Our steganographic technique also achieves a good Peak Signal to Noise Ratio as well as a good Structural Similarity Index value. © 2015 The Authors. Published by Elsevier B.V.

Microbial proteases that occupy a pivotal position with respect to their commercial applications are most important hydrolytic enzymes and have been studied extensively since the advent of enzymology. Cold-adapted microorganisms are potential source of cold-active proteases and they have been isolated from the cold regions. Although there are many microbial sources available for producing proteases, only few are recognized as commercial producer. Cold-active proteases along with their producing microbes are of commercial value and find multiple applications in various industrial and biotechnological sectors such as additives in detergents, additives in food industries, environmental bioremediations, biotransformation and molecular biology applications. Therefore, cold-active proteases are the enzymes of choice for many biotechnologists, microbiologists, biochemists, environmentalists and biochemical engineers. In the present review, we discuss some novel sources along with recent developments in production and biotechnological applications of cold-active microbial proteases. © 2012 Informa Healthcare USA, Inc.

The concentration of twenty-three polycyclic aromatic hydrocarbons (PAHs) were measured in the outdoor environment of rural homes in the North central part of India during three consecutive season winter, summer and rainy (November 2006-October 2007). The gaseous phase PAHs were collected by using XAD-2 resin tubes (600 mg) followed by a PTFE filter paper (37 μm dia) for particulate bound PAHs at a flow rate of 3 Lpm for 24 h. The individual PAHs were identified by using a gas chromatograph with mass spectrometry detector (GC/MS). The results showed that average concentration of (gas + particulate) PAHs varied with season. It ranged from (21.91-1290.50 ng/m 3) being the highest in winter, lower in summer (11.18-613.00 ng/m 3) and lowest in the rainy season (13.10-272.50 ng/m 3) respectively. The total PAHs concentrations in the air were 32.56% and 61.97% higher in winter season from summer and rainy season respectively. It was indicated that the two, three and four rings PAHs were predominantly in gaseous phase while the five and six rings PAHs were primarily associated with the particulate phase. Among the 23 PAHs, naphthalene was the most abundant PAH. It contributed 30.99-55.81% to the sum of PAHs in three different seasons. The trend of the concentrations of the major PAHs found in present study were Nap > 2 methyl Nap > 1 methyl Nap > biphenyl > acenapthylene at all the sampling locations. The average BaP equivalent exposure, calculated by using toxic equivalent factors was approximately 27.95 ng/m 3. Correlation and factor analysis was applied to identify the probable sources of PAHs. © 2012 Elsevier B.V.

An extensive range of pigments including phycobiliproteins are present in algae. C-phycocyanin (C-PC), a phycobiliprotein, is one of the key pigments of Spirulina, a microalgae used in many countries as a dietary supplement. Algal pigments have massive commercial value as natural colorants in nutraceutical, cosmetics, and pharmaceutical industries, besides their health benefits. At present, increasing awareness of harmful effects of synthetic compounds and inclination of community towards the usage of natural products have led to the exploitation of microalgae as a source of natural pigments/colors. This review describes recent findings about the sources and production of C-PC, with emphasis on specific techniques for extraction and purification, along with potential industrial applications in diagnostics, foods, cosmetics, and pharmaceutical industries. © 2013 M.

A novel laccase enzyme producing bacterium, Pseudomonas putida MTCC 7525, was isolated and subjected to optimization of laccase production. Maximum production (94.10. U/ml) was achieved at 30. °C and pH 8 (108. h incubation) with 10% skim milk and 1. mM sodium nitrate as additional nitrogen source. The laccase was purified by salt precipitation followed by ion exchange chromatography which showed 6.44 fold purification. The purified enzyme had optimal activity at pH 8.0 and 40. °C, and showed stability in DMSO retaining more than 85% of original activity. In presence of manganese and cadmium, enzyme retained >95% and 92% activity, respectively. The molecular weight of laccases was 39.5. kDa and activity was inhibited by pCMB (93%). The synthetic dyes (0.02%) and industrial effluents (10%) were decolorized to 74-93 and 58-68%, respectively when treated with culture of P. putida. However, the culture supernatant of P. putida showed about 36-94 and 16-86% decolorization of synthetic dyes and effluents, respectively within 24. h of incubation. © 2013 Elsevier Ltd.

The process-based Soil and Water Assessment Tool (SWAT) model and the data-driven radial basis neural network (RBNN) model were evaluated for simulating sediment load for the Nagwa watershed in Jharkhand, India, where soil erosion is a severe problem. The SWAT model calibration and uncertainty analysis were performed with the Sequential Uncertainty Fitting algorithm version 2 and the bootstrap technique was applied on the RBNN model to analyse uncertainty in model output. The percentage of data bracketed by the 95% prediction uncertainty (95PPU) and the r factor were the two measures used to assess the goodness of calibration. Comparison of the results of the two models shows that the value of r factor (r = 0.41) in the RBNN model is less than that of SWAT model (r = 0.79), which means there is a wider prediction interval for the SWAT model results. More values of observed sediment yield were bracketed by the 95PPU in the RBNN model. Thus, the RBNN model estimates the sediment yield values more accurately and with less uncertainty. © 2014 © 2014 IAHS Press.
