2. Amassing of Hydroxymethylfurfural, 2- Furfural and 5- Methyl furfural in orange (Citrus reticulata) juice during storage
Abstract Vitamin C is imperative component of our nutrition and used as additive in many foods owing to its high antioxidant activity. The degradation of vitamin C content in orange juice during storage was evaluated in this study. Degradation of vitamin C in orange juice during 40 days storage at 0, 05, 15, 25, and 40 °C was analyzed and evaluated. Hydroxy

3. Longer crop cycle lengths could offset the negative effects of climate change on Brazilian maize
ABSTRACT Maize (Zea mays) is considered one of the most important crops for world food security. Globally, Brazil is the second largest maize producer and the fourth largest maize consumer. The climate variables is one of the main determining factors for crop yield. Given the possibility of future climate changes, our objective was to evaluate the impact of

5. Influence of high-frequency microwave radiation on montmorillonite structure parameters
Resumo A influência da radiação micro-ondas nas alterações estruturais das partículas de montmorilonita foi estudada em uma amostra de argila montmorilonítica. Processos de longo alcance em múltiplas escalas foram induzidos nos aluminossilicatos naturais por radiação de micro-ondas de baixa e média potência (2,45 Hz, 750 W, 10 min). Amostras em p

7. Methane emission induced by short-chain organic acids in lowland soil
ABSTRACT Methane (CH4) is the second major greenhouse gas after CO2, exerting a significant influence on the climate and the chemistry of the atmosphere. In lowland soil, acetate and H2/CO2 are the most important precursors of CH4 and formed from organic matter fermentation in an anaerobic environment, giving rise to short-chain organic acids (ethanoic, prop

8. Microstructural Adjustments and Tensile Properties of a Hot-Forged Ti−22Al−23Nb−3V−Y Alloy
Microstructures and tensile properties of a hot forged Ti−22Al−23Nb−3V−Y alloy were investigated systematically. Different heat treatments were performed to adjust the wrought microstructure to optimize tensile properties. It was found that features of O phase precipitates and its volume fraction was rather sensitive to the cooling rate after the sol

9. Physiological and Molecular Responses in Rice, Weedy Rice and Barnyardgrass Exposed to Supra-Optimal Temperatures
RESUMO: A temperatura média global pode aumentar de 0,3 a 4,8 oC até o final do século. Temperaturas supraótimas podem afetar as plantas em diferentes níveis organizacionais, causando alterações morfológicas, fisiológicas, bioquímicas e na expressão de genes, e plantas de arroz, arroz-vermelho e capim-arroz tendem a responder de forma distinta qua

10. Effect of convective and microwave methods on drying characteristics, color, rehydration and microstructure properties of ginger
Abstract In this research, the effects of convective drying method (60, 70 and 80 °C) and microwave drying method (160 and 350 W) on the drying characteristics, color, rehydration and microstructure properties of ginger has been examined. For the purpose of choosing the most appropriate thin-layer drying models in terms of the drying applications, nine math

12. Influence of reaction temperature on the generation of gels during EVA production in tubular reactor
ABSTRACT The fouling formation in the EVA production leads to an increase in the residence time of the material. This result is a favorable condition to generation of the crosslinks during the polymerization. The crosslinking allows raising the molar mass of the polymer, which after the polymerization reaction are characterized as gels, thus generating probl
