As a moderately drought tolerant crop, lentil is a major crop in rainfed areas and a suitable candidate for drought stress tolerance research work. Screening for drought tolerance stress under hydroponic conditions at seedling stage with air exposure is an efficient technique to select genotypes with contrasting traits. Transcriptome analysis provides valuable resources, especially for lentil, as here the information on complete genome sequence is not available. Hence, the present studies were carried out. This study was undertaken to understand the biochemical mechanisms and transcriptome changes involved in imparting adaptation to drought stress at seedling stage in drought-tolerant (PDL-2) and drought-sensitive (JL-3) cultivars. Among different physiological and biochemical parameters, a significant increase was recorded in proline, glycine betaine contents and activities of SOD, APX and GPX in PDL-2 compa...

Trioxepane 11c, the most active compound of the series, showed more than 98% suppression of parsitaemia at 96 mg/kg by both oral and intramuscular routes. This is the first report on in vivo active 1,2,4-trioxepanes.

Molecular assortment based on 46 simple sequence repeat (SSR) markers clustered the genotypes into 11 groups, where wilds were separated from the cultigens. Genetic diversity and polymorphism information content (PIC) varied between 0.148-0.775 and 0.140-0.739, respectively. Breeding lines which were found to be most resistant (L-7903, L-4602); sensitive cultivars (BM-4, L-4147) and wilds ILWL-185 (resistant), ILWL-436 (sensitive) were grouped into different clusters. These genotypes were also separated on the basis of population structure and Jaccard's similarity index and analysed to study Al resistance mechanism through determination of different attributes like localization of Al and callose, lipid peroxidation, secretion of organic acids and production of antioxidant enzymes. In contrast to sensitive genotypes, in resistant ones most of the Al was localized in the epidermal cells, where its movement to apoplastic region was restricted due to release of citrate and malate. Under acidic field conditions, resistant genotypes produced maximum seed yield/plant as compared to sensitive genotypes at two different locations i.e. Imphal, Manipur, India and Basar, Arunanchal Pradesh, India during 2012-13, 2013-14 and 2014-15. These findings suggest that Al stress adaptation in lentil is through exclusion mechanism and hybridization between the contrasting genotypes from distinct clusters can help in development of resistant varieties.

These techniques are primarily based on converting the voting procedure to a hierarchy based voting method. These methods use approximate decision-making process. In this paper, we propose a fast decision making process that enhances the speed and reduces the space requirements. Experimental results demonstrate that the proposed algorithm is much faster than a similar Fast Hough Transform.

The aim is to understand the fundamental processes and enhance photocatalytic efficiencies especially for air, soil and water pollution control. Municipal waste water is limited by continual organic water pollutants and micro-organisms that are not removed by conventional mechanical and biological treatment. In this overview of the most recent paper, studies focused on the treatment of municipal wastewater (containing organic compounds) by photocatalysis and the effects of various parameters such as pH, light intensity, Advance oxidation method etc. have been studied It can be concluded that the photocatalysis process is suitable for the treatment of drinking water, municipal and industrial wastewater. Some studies on the economic analysis of photocatalytic systems are also included.

The digitization process compromises the accuracy of the moments and therefore, several of its properties are affected. There are two major discretization errors, namely, the geometric error and numerical integration error. In this paper we propose two new algorithms which eliminate these errors. The first algorithm performs the exact computation of geometric moments (GMs) over a unit disk and then uses GMs-to-ZMs relationship to compute the latter. This algorithm is computationally more expensive and it becomes numerically instable for higher order moments, therefore, we develop a second algorithm based on Gaussian quadrature numerical integration. The second algorithm reduces both the errors simultaneously and its accuracy increases as the degree of Gaussian quadrature numerical integration increases. The proposed algorithms are observed to provide very accurate ZMs which result in improved image reconstruction, reduction in reconstruction error and improvement in rotation and scale invariance. Exhaustive experiments are provided to support improved accuracy of ZMs and time complexity analysis is performed for the existing and the proposed methods.

Photoreduction, deposition, and dark adsorption of Cr6+, Cu2+, Ni2+, and Zn2+ metal ions have been investigated using TiO2 with UV-irradiated. Also investigated that citric acid as a hole scavenger and hydrogen peroxide as a oxidant at pH values 2, 4, 6–8, and 10. The modeling of metal species has been performed and speciation is used as a tool for discussing the photo reduction and deposition trends. The modeling of metal species at different pH values has been performed. It was observed that the photocatalytic process was effective in removing most of the metal ions in specific reaction circumstances. The maximum reduction and deposition of Cr and Cu2+ were found to be favorable at acidic pH 2–4, while Ni2+ and Zn2+ reductions were found to be most suitable at neutral to alkaline pH 10. The photocatalytic reduction and deposition trend of the metal ions prove the theoretical thermodynamic predictions about a reaction time period (5 h).

In the hybrid approach both local and global features of images are combined, which represent the entire aspects of images. Local features are extracted using Fourier descriptors and global features are extracted by means of angular radial transform. The results of combining both these descriptors demonstrate that the proposed solution provides significant improvement in image retrieval accuracy as compared to using global and local features autonomously. Besides, it also outperforms existing recent hybrid approaches to image retrieval.
