A facile, one-step and greener route for the synthesis of gold nanoparticles (AuNPs) was developed in pursuit of an eco-friendly alternative via green synthesis of gold nano-materials. Mangifera indica (mango) is one of the most popular fruits and key herb in the Ayurvedic and ethno-veterinary-medical systems for several thousand years. We report here for the first time the AuNPs synthesis from auric chloride salt using aqueous extract of M. indica flowers as reducing and stabilizing agent. The biosynthesis process was fast with most of the AuNPs forming within 20 minutes and the reaction-kinetics reaching a plateau in just an hour. The AuNPs were characterized by UV-Vis absorption spectroscopy, TEM, high-resolution transmission electron microscopy (HRTEM), energy dispersive X-ray (EDX) spectroscopy, nanoparticle tracking analysis (NTA), dynamic light scattering (DLS) measurements and Fourier-transform infrared (FTIR) spectroscopy, which confirmed the bio-reduction of gold ions. The bio-reduced AuNPs were mostly spherical with a dimension range nearer to 10-60 nm by TEM and a modal size of 32 nm by NTA. These AuNPs exhibited excellent nanocatalysis in the reduction of 4-nitrophenol to 4-aminophenol by NaBH4 in aqueous phase. These biogenic gold nanoparticles could be useful for remediation of waste-waters and effluents containing nitroarene, such as 4-Nitrophenol. © 2017 American Institute of Chemical Engineers Environ Prog.

Identification of a suitable cultivation method with low energy use, GWP and high productivity is the need of the hour. A 16-year old field study in the Indo-Gangetic Plains (IGP) with different methods of rice cultivation viz., zero tillage (ZT), happy turbo seeder (HTS), bed planting (BP), reduced tillage (RT), conventional sowing (CS), direct sowing (DS), broadcast method of sowing (BS), manual transplanting (HT) and selected transplanting methods like, manual transplanter (MT) and mechanical transplanter (MaT) was used to evaluate the energy input and GWP. HT method of rice cultivation recorded higher energy use than ZT, HTS, BP, RT, CS, DS and BS methods, respectively. Whereas HTS method recorded highest net grain energy (NEg) and this was followed by ZT and MaT, The PTR method recorded 61–66% higher GWP compared with direct sown unpuddled method of rice cultivation. Among direct sown unpuddled methods of rice cultivation, HTS, BP, RT and ZT had lower GWP than farmers' practice. MaT recorded higher carbon output than ZT, HTS, BP, RT, CS, DS and BS methods. The study indicated that direct seeded method of rice cultivation is energy efficient with lower GWP and thus may be recommended. © 2017 Elsevier Ltd

Frequent occurrences of extreme rainfall events create severe threat to agricultural production. This is one of the most significant consequences of global warming due to increase in greenhouse gases. A precise understanding of frequency and magnitude of these events and its influence on agricultural productivity can extensively help in policy decisions and planning agricultural as well as water management operations. This study has analyzed observed trends in extreme rainfall indices during monsoon months as well as seasonally at four stations located over different agro-ecological zones of Bihar, namely Samastipur (zone-I), Madhepura (zone-II), Sabour (zone-IIIA) and Patna (zone-IIIB). Mann-Kendall nonparametric test was employed for detection of trends and the slopes of the trend lines were determined using the method of least square linear fitting. Since rice is the important crop in this part of the region, the vulnerability of extreme rainfall indices on productivity also analysed using simple correlations. All the sites show an increasing trend of number of days with rainfall 10.0. cm or more (very heavy precipitation event) during monsoon season. Sabour shows a significant increasing trend of 0.4 and 0.6 day/decade, respectively during monsoon and annually. During September, occurrence of heavy precipitation events over Madhepura recorded a significant positive trend of 0.4 day/decade. Highly significant magnitudes of increasing trends were noticed for Madhepura (46.6. mm/decade) and Sabour (27.5. mm/decade) for occurrence of highest five-day total precipitation during monsoon season. The results show statistically significant positive trends of number of days with rainfall > R2.5. cm for all the study sites during August. All the sites, the magnitude of highest 1-day and 5-days maximum rainfall is showing increasing trend. Increasing trends of fraction of rainfall due to extremely wet days is also showing increasing trend in all the sites. The rice productivity showed 10th degree polynomial technological trend in all the sites and steady increase in all the sites except Samastipur. The correlation between extreme rainfall indices during monsoon season and productivity anomaly index indicate that almost all the extreme rainfall indices contribute positively to rice productivity except P95pTOT and R99pTOT over Sabour and R7.5. cm over Patna. If we assume the observed increasing trends in different extreme rainfall indices will continue, as estimated by the global circulation models, the chances of occurrence of intense rainfall events in near future will also increase proportionally and efforts should be made to prepare detailed site specific-at least at district level-disastrous management plan especially to reduce impact of extreme rainfall event on agricultural production system under changing climatic scenarios. © 2011 Elsevier B.V.

Indigenous Tribal Agricultural Practices (ITAPs) have facilitated intensive farming for a long period of time without significant deterioration of land or decline in crop production. The tribes of the Kolli hills of Namakkal district in Tamil Nadu possessed rich tradition, heritage and experience in agriculture. Their rich wisdom in ITAPs can effectively be utilized for sustainable agricultural development of tribal areas by appropriately blending the ITAPs with recommended production technological package. In this context, a study was done for collecting, classifying, documenting, analyzing the rationality, and studying the adoption of the selected ITAPs in low land paddy. About 65 ITAPs on low land paddy, in different clusters of villages of Kolli hills were documented. For assessing the rationality, the selected ITAPs were divided into two groups. The first group consisted of 35 ITAPs were related to crop production and the second 30 ITAPs were related to plant protection. Having identified and selected the list of ITAPs with their rationality scores, further analysis was undertaken to test verify their extent of adoption. The rational and effective ITAPs should be blended into the technology package for transfer of technology, so that the agricultural development will be sustainable. © 2015, National Institute of Science Communication and Information Resources (NISCAIR).

This paper is focused on the detection of counterfeit photocopy banknotes. The main difficulty is to work on a real industrial scenario without any constraint about the acquisition device and with a single image. The main contributions of this paper are twofold: first the adaptation and performance evaluation of existing approaches to classify the genuine and photocopy banknotes using background texture printing analysis, which have not been applied into this context before. Second, a new dataset of Euro banknotes images acquired with several cameras under different luminance conditions to evaluate these methods. Experiments on the proposed algorithms show that mixing SIFT features and sparse coding dictionaries achieves quasi perfect classification using a linear SVM with the created dataset. Approaches using dictionaries to cover all possible texture variations have demonstrated to be robust and outperform the state-of-the-art methods using the proposed benchmark. © 2016 IEEE.

The overall objective of ID_MOBILE is the development of a market-ready multiplatform system to verify the authenticity of identity documents by means of smartphones and tablets, based on a patent of our property and long commercial experience in the sector. This innovation will drive the change of our companys current license-based model to a Cloud-based service model as part of our plan for growth into new markets worth 300 million over a 4-year period. At ICAR Vision Systems we have spent the last ten years providing our clients banks, hotels, casinos, telecoms and IKEA, among others with the technological edge in the automated detection of document fraud. ID_MOBILE is part of our ID Cloud platform designed to enable smartphones and tablets to reliably perform the same ID reading and verification tasks as our desktop-based systems. This will help solve client support and capture bottlenecks in sectors like Financial Services and Consumer Credit, Hotels and Resorts, Insurance, Telecom, Utilities and others that use validation to avoid identity fraud, a problem that causes losses of up to 500 billion to European companies and 20 billion to EU individuals, according to Commission estimates. The feasibility assessment intended to be undertaken in Phase 1 covers a series of technical issues regarding the capture and processing of identity documents with mobile devices, including the choice of image capture improvement tools for development, the feasibility of facial recognition features, of manual verification modules for detected fraud and of data acquisition by streaming video. Also studied are issues related to the business plan, such as an in-depth market study of new sectors and services, IPR protection and a partner search for technology integrators.
