A Web crawler is a module of a search engine that fetches data from various servers. Web crawlers are an essential component to search engines; running a web crawler is a challenging task. It is a time-taking process to gather data from various sources around the world. Such a single process faces limitations on the processing power of a single machine and(More)
BACKGROUND Tobacco use in India is characterized by a high prevalence of smoking and smokeless tobacco use, with dual use also contributing a noticeable proportion. In the context of such a high burden of tobacco use, this study examines the regional variations, and socioeconomic, demographic and other correlates of smoking, smokeless tobacco and dual use(More)
In computer vision, segmentation refers to the process of partitioning a digital image into multiple segments (sets of pixels, also known as superpixels).Image segmentation is typically used to locate objects and boundaries (lines, curves, etc.) in images. More precisely, image segmentation is the process of assigning a label to every pixel in an image such(More)
Impact of supplemental UV-B (sUV-B) has been investigated on photosynthetic pigments, antioxidative enzymes, metabolites, and protein profiling of radish plants under realistic field conditions. Exposure of sUV-B leads to oxidative damage in plants. However, plants possess a number of UV-protection mechanisms including a stimulation of antioxidant defense(More)
OBJECTIVES This study assessed the significance of socio-demographic and contextual factors on the number of daily cigarette and bidi smoking in northeast India. METHODS This study is based on the data from the Global Adult Tobacco Survey-India (2009-2010). Community asset is measured as the totality of all households' durables and community affinity to(More)
OBJECTIVES This study aims to investigate the role of different factors associated with exposure to second-hand smoke (SHS) in the workplace and home in the urban and rural areas of India. DESIGN Secondary analysis of the data from the Global Adult Tobacco Survey conducted in 2009-2010. SETTING AND PARTICIPANTS Data were analysed from 32 738 rural and(More)
Magnetic Resonance Image plays a major role in medical diagnostics. Image segmentation is done to divide an image into meaningful structures. Image segmentation is the initial step in image analysis and pattern recognition. It becomes more important while dealing with medical images where pre-surgery and post-surgery decisions are required for the purpose(More)
AIMS To study the genetic basis of C(4)-dicarboxylate transport (Dct) in relation to symbiotic nitrogen fixation in Mesorhizobium ciceri. METHODS AND RESULTS A Tn5-induced mutant strain (TL16) of M. ciceri, unable to grow on C(4)-dicarboxylates, was isolated from the wild-type strain TAL 620. The mutant lacked activities of the enzymes, which use(More)
