Large grain UO 2 is considered as an accident tolerant fuel with great application potential due to its competitive advantage of good fission gas retention. In this paper, the influence preparation parameters such sintering atmosphere, mixing process, powder pretreatment and growth additives on size systematically studied. The result shows that factors mentioned above have different effects . p...

Cigarette production involves a number of substances and materials other than just tobacco, paper and a filter. Tobacco additives include flavorings, enhancers, humectants, sugars, and ammonium compounds. Although companies maintain that tobacco additives do not enhance smoke toxicity and do not make cigarettes more attractive or addictive, these claims are questioned by independent researchers...

Drought stress decreases crop growth, yield, and can further exacerbate pre-harvest aflatoxin contamination. Tolerance and adaptation to drought stress is an important trait of agricultural crops like maize. However, maize genotypes with contrasting drought tolerances have been shown to possess both common and genotype-specific adaptations to cope with drought stress. In this research, the phys...

The article considers the balance of engine oil aging components in diesel lubrication system with refinement composition caused by product loss. motor process has been identified under continuous and periodic refill order to replenish fresh which would compensate burnt off products. There were derived solved differential equations for such aspects as contamination insoluble impurities multifun...

Plastic contamination is ubiquitous in the environment and has been related to increasing global plastic usage since 1950s. Considering omnipresence of additives plastics, risk posed by this not only physical effects particles but also their additive content. Until now, most routine environmental monitoring programs involving have considered presence these still associated with they were added ...

The contamination of foods and feeds is a significant problem in worldwide. Mycotoxins are secondary metabolites of fungi, particularly by many species of Aspergillus, Fusarium, Penicillium, Claviceps and Alternaria in many agricultural crops, especially in cereals and most oilseeds. Aflatoxins, ochratoxins, trichothecenes, zearelenone and fumonisins are the mycotoxins of greatest agro-economic...

The ubiquitous nature of Listeria monocytogenes and its ability to grow at refrigerated temperature makes L. monocytogenes a significant threat to the safety of ready-to-eat (RTE) meat products. The contamination by L. monocytogenes in RTE meat primarily occurs during slicing and packaging after cooking. The effectiveness of postpackage decontamination technology such as in-package thermal past...
