13. Adaptation of the Pediatric Smell WheelTM to evaluate olfactory function in Brazilian children
Abstract Objective: Olfaction influences nutrition, safety, and the cognitive development of children. Presently there are few olfactory tests for children, and normative reference values are generally lacking. In this study, we validate the Pediatric Smell WheelTM (PSW) to evaluate olfactory function in Brazilian children. Methods: We modified and validat

14. Different Degradation Patterns of Chiral Contaminant Enantiomers: Paclobutrazol as a Case Study
Studies often neglect the different trends between enantiomers in soil chiral contaminants. In the present study, paclobutrazol was chosen as the target analyte and the selective degradation patterns of this chiral pesticide were investigated in soils. After 14 days of culture, the degradation kinetics results demonstrated the degradation process of the two

17. Effect of calcium concentration on calcite flotation from apatite using carbonic gas
Abstract The flotation process currently considered for apatite concentration from the Santa Quitéria phosphate deposit (Brazil), involves bulk flotation of apatite and calcite with anionic collector at pH=10 followed by calcite flotation at pH=5.5, adjusted with H3PO4. Although this concept is efficient from the point of view of separation between apatite

19. Optimization of sunflower oil bleaching parameters: using Response Surface Methodology (RSM)
Abstract Bleaching is an important part of the oil refining process, in which pigments, impurities, traces of metals, and oxidative-molecular components of oils are removed. In this regard, the optimization of bleaching conditions can be effective to increase oil quality. In this study, de-gummed and neutralized sunflower oil was bleached at 80, 90, 100, 110

20. Chemical composition and fatty acids profile of chocolates produced with different cocoa (Theobroma cacao L.) cultivars
Abstract The objective of the present study was to characterize the physicochemical composition and to quantify the fatty acids of chocolates produced from different cocoa varieties (Theobroma cacao L.) cultivated in the Southern Region of Bahia. Nine samples of monovarietal chocolates were evaluated, according to their physical, thermal and fatty acid profi

22. Regenerated Cellulose Membrane from Peanut Shell for Biodiesel Purification
Biodiesel purification by water washing has been proved to be an unattractive process from an economic and environmental point of view. In this work, we propose the use of regenerated cellulose membranes from peanut shell as an alternative in the biodiesel purification. The preparation of the membranes was optimized from a central composite design, resulting

23. FUZZY SLIDING-MODE TEMPERATURE-CONTROL SYSTEM FOR SOAKING AND GERMINATION OF RICE SEEDS
ABSTRACT The soaking and germination process of rice seeds is the starting point in rice cultivation in cold regions and has a significant effect on grain yield. Efficient techniques for controlling the water temperature in the seed tank are required to enhance germination quality. This paper introduces a fuzzy theory for designing a fuzzy logic-based slidin
