introduction and aims: both observational and experimental studies have shown that higher selenium status reduces the risk of upper gastrointestinal cancers in selenium deficient populations. recent cancer registry data have shown very different rates of esophageal cancer (ec) and gastric cancer (gc) in four provinces of iran, namely ardabil, mazandaran, golestan, and kerman. the aim of this st...

Grapevine is highly susceptible to fungal diseases, whose incidence and severity increase due climate change. The present work focuses on the assessment of eight combinations natural products with chitosan oligomers fungicidal capacity that may be effective in integrated control powdery mildew, compliance Article 14 European Directive 2009/128/EC. Their efficacy was evaluated field conditions a...

This study developed and validated an analytical methodology for the determination of aflatoxins, enniatins, beauvericin, zearalenone, ochratoxin-A, alternariols, HT-2 T-2 toxin in soy, oat, rice almond beverages, based on solid phase extraction columns (SPE) analyzed by liquid chromatography coupled to mass spectrometry tandem. C18 SPE was successfully applied, obtaining recoveries that range ...

Simon and Speck are two families of ultra-lightweight block ciphers which were announced by the U.S. National Security Agency in June 2013. Yet, the specification discusses only the design and the performance of both cipher families and the task of analyzing their security has been left to the were proposed by the U.S. National Security Agency in June 2013. Yet, the specification paper discusse...

We propose a new 128-bit blockcipher CLEFIA supporting key lengths of 128, 192 and 256 bits, which is compatible with AES. CLEFIA achieves enough immunity against known attacks and flexibility for efficient implementation in both hardware and software by adopting several novel and state-of-the-art design techniques. CLEFIA achieves a good performance profile both in hardware and software. In ha...
