Safety concerns pertaining towards fungal occurrence and mycotoxins contamination in agri-food commodities has been an issue of high apprehension. With the increase in evidence based research knowledge on health effects posed by ingestion of mycotoxins-contaminated food and feed by humans and livestock, concerns have been raised towards providing more insights on screening of agri-food commodities to benefit consumers. Available reports indicate majority of edible oil-yielding seeds to be contaminated by various fungi, capable of producing mycotoxins. These mycotoxins can enter human food chain via use of edible oils or via animals fed with contaminated oil cake residues. In this review, we have decisively evaluated available data (from the past decade) pertaining towards fungal occurrence and level of mycotoxins in various oil seeds and their edible oils. This review can be of practical use to justify the prevailing gaps, especially relevant to the research on presence of mycotoxins in edible plant based oils. © 2016 Elsevier Ltd

Hand-pressed strawberry juice samples were subjected to sonication treatments (0, 15 and 30 min at 20 °C, 25 kHz frequency). Physicochemical properties (°Brix, pH, water activity, viscosity, titratable acidity, cloud assessment and turbidity), antioxidant compounds and activity (total phenolics, ascorbic acid, anthocyanins, free radical scavenging activity), polyphenoloxidase enzyme activity, browning degree and microbial load were evaluated. Results showed non-significant changes for °Brix, pH, water activity, titratable acidity and colour parameters in sonicated samples compared to control (0 min). Sonication treatments resulted in reduced viscosity and increased cloudiness and turbidity. Overall, treatment for 30 min showed significant enhancement in bioactive compounds under study. Besides, sonication treatment imparted non-significant changes in polyphenoloxidase activity and in browning degree. However, sonication was incompetent in reducing microbial load. Results generated from this study were encouraging and this is expected to provide platform for future commercial applications on a pilot scale. © 2016 Elsevier Ltd

Digital signature scheme is an important cryptosystem for demonstrating the authenticity of a digital message and is used often to implement electronic signatures. This paper proposes a digital signature scheme based on a ring of N-truncated single-variable polynomials over a finite field of prime order. Its security is tied to the twisted ring-root extraction problem over the finite field. We assume that this problem is suitably hard problem to serve as a cryptographic assumption over the platform ring R. It is noted that an adversary cannot forge a signature on a message unless the adversary extracts the twisted eth-root in this ring. The performance and other security issues are also discussed. © 2016 IEEE.

Renewable and Sustainable Energy Reviews | Year: 2014

Energy planning can be defined as a roadmap for meeting the energy needs of a nation and is accomplished by considering multiple factors such as technology, economy, environment, and the society that impact the national energy issues. Long-term energy planning is a strategic approach to study how structural changes of a nation would affect the energy demand and supply. This is done through scenario analysis which would also cater for uncertainty in planning. Good energy plan would ensure sustainable development which acts as a guiding factor for any energy scheme. In this paper, we present an overview of the different facets of energy planning based on a comprehensive literature review. It present the risks, uncertainties and errors involved in energy planning. The econometric, optimization and simulation models are reviewed and five appropriate computer models, that can be used for a small developing island nation's long-term energy planning using scenario analysis, are discussed. This paper also discusses the inquiry method and elaborates on why it can be used for energy planning in small developing island countries. Validation process of energy models is also presented and finally, recommendations are made for energy planners. © 2014 Elsevier Ltd.

The liquid chromatography method for simultaneous determination of seven carbamate pesticides, viz. aldicarb, benomyl, carbofuran, ethiofencarb, methomyl, thiophanate ethyl and thiophanate methyl has been described. The method employed a Zorbax Eclipsed XGB C-8, column and 30:70 acetonitrile-water mixture (v/v) as mobile phase with UV detection at 235 nm. Good separation of all these carbamates was achieved at 1 mL/min flow rate of the mobile phase at 25 °C. Their recovery from food grains fenugreek leaves and apples was found to be > 80%. The commercial grade carbamate formulations containing benomyl, carbofuran, methomyl and thiophanate methyl were also analyzed and residue levels of these commercial formulations on selected food matrices were analyzed for comparison. The method had good peak resolution, high precision, low limit of detection and high degree of reproducibility. It could be applied for rapid screening and quantization of these carbamates in real sample matrices sold in the local markets. © 2012 Elsevier B.V.

Obesity Reviews | Year: 2013

Summary: The Pacific Island countries experience some of the highest rates of obesity in the world in part due to substantial dietary changes that mirror changes in the food supply in the region. Economic and political ties, donor aid, and trade links are key drivers of the changing availability and accessibility of processed and imported foods. Pacific Island countries have been innovative in developing trade-related policy approaches to create a less obesogenic food environment. Taxation-based approaches that affect pricing in the region include increased import and excise tariffs on sugared beverages and other high-sugar products, monosodium glutamate, and palm oil and lowered tariffs on fruits and vegetables. Other approaches highlight some higher-fat products through labeling and controlling the supply of high-fat meats. The bans on high-fat turkey tails and mutton flaps highlight the politics, trade agreements and donor influences that can be significant barriers to the pursuit of policy options. Countries that are not signatories to trade agreements may have more policy space for innovative action. However, potential effectiveness and practicality require consideration. The health sector's active engagement in the negotiation of trade agreements is a key way to support healthier trade in the region. © 2013 The Authors.

In recent times, gold has been one of the prioritized commodities in terms of long term as well as short term investments since the investors consider gold as a hedgerow against the unforeseen events leading to chaos in the market. Consequentially, the price of gold in the market plays an important role. In this research work, time-series gold price prediction models have been developed using the support vector regression and anfis models for the prediction of daily gold prices. The support vector model was designed using epsilon support vector regression method while the adaptive neural fuzzy inference systems have been developed using grid partition and subtractive clustering methods. The gold prices obtained for the training and testing were obtained from Perth Mint of Australia. The evaluation criteria for the comparison of the models are Mean Absolute Error (MAE), Root Mean Square Error (RMSE), Nash-Sutcliffe model efficiency coefficient (E) and Mean absolute percentage error (MAPE). It was observed that the models obtained using support vector regression outperformed the ANFIS models. In the ANFIS models, it was observed that ANFIS-GP performed slightly better than the ANFIS-SC model. © 2016 IEEE.

Impact of ultraviolet (UV-C) radiation treatments (0, 15, 30 and 60 min) on freshly extracted tomato juice quality (physicochemical properties, antioxidant activity and microbial load) was evaluated. On exposure to UV-C, level of water activity, total soluble solids, and titratable acidity exhibited non-significant increase up to 30 min of exposure time. Regarding colour analysis, L∗ value significantly increased with subsequent decrease in a∗ and b∗ values post UV-C treatments. Clarity, DPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging activity and total phenolics content significantly increased, whereas ascorbic acid level significantly reduced at 60 min of UV-C exposure time. So also, lycopene content exhibited a non-significant decrease after UV-C treatment. Microbial studies showed reduction in total plate count and total mould counts post UV-C treatment. Overall, UV-C treatment being a physical, non-thermal method of food preservation holds the ability to improve or preserve vital quality parameters in freshly prepared tomato juices, and henceforth possesses high scope for commercial exploration. © 2016 Elsevier Ltd

The current literature on the relationship between electricity, exports and economic growth is mixed. This paper examines the relationship between exports, electricity consumption and real income per capita in Japan using time series data from 1960-2007. We applied bounds testing procedure developed by Pesaran et al., (2001) and found that there is cointegrating relationship between electricity consumption, exports and economic growth. On establishing cointegration, the causal relationship electricity consumption, exports and economic investigation was investigated within a Vector Error Correction Model (VECM) framework. We found that in the long run, there is causality from exports and real GDP per capita to electricity consumption.
