13. Stability of porridge pre-mixture made with Brazil nut flour and green banana flour with and without milk powder
The mixture of Brazil nut flour and green banana flour can improve the nutritional value of school meals, allowing for the use of regional ingredients derived from family agriculture. This study aimed to assess the stability of porridge pre-mixtures made with Brazil nut flour and green banana flour during six months of storage. Two types of pre-mixture were

14. Experimental Study of Polyurethane-Based Fuels with Addition of Paraffin and Aluminum for Hybrid Rocket Motors
ABSTRACT: Experimental investigation was conducted to determine the relative propulsive and combustion behavior of several polyurethane-based solid-fuel formulations containing 30% w/w of paraffin or 10% of aluminum powder. In total, seven solid-fuel formulations were investigated, four containing 30% of paraffin and three with 10% of aluminum. The polyureth

15. Large Eddy Simulation of Bluff Body Stabilized Turbulent Premixed Flame
ABSTRACT: A turbulent reacting flow in a channel with an obstacle was simulated computationally with large eddy simulation turbulence modeling and the Xi turbulent combustion model for premixed flame. The numerical model was implemented in the open source software OpenFoam. Both inert flow and reactive flow simulations were performed. In the inert flow, comp

16. Characterization of pre-gelatinized rice and bean flour
The objective of this study was to develop a pre-gelatinized flour using a mixture of broken rice and split beans by thermoplastic extrusion, and to evaluate the physicochemical, nutritional, and technological quality of the final product. The extrusion parameters were maintained using three heating zones with temperatures of 30 ºC, 40 ºC, and 70 ºC; scre

17. Single and sequential applications of metconazole alone or in mixture with pyraclostrobin to improve Fusarium head blight control and wheat yield in Brazil
Four fungicide trials were conducted in northern RS state during 2009. Six treatments, from the combination of one (flowering = F) or two applications (F + 10 days) of metconazole sprayed alone or in mixture with pyraclostrobin were tested. Fusarium head blight incidence (INC) and severity (SEV) were assessed at the pre-harvest period and Fusarium-damaged ke

18. Simultaneous determination of Pb and Cd in seafood by ICP OES with on-line pre-concentration by solid phase extraction with amberlite XAD-4 after complex formation with DDTP
An on-line method for Cd and Pb pre-concentration and simultaneous determination in acid digested seafood by inductively coupled plasma optical emission spectrometry (ICP OES) was developed. The on-line pre-concentration was based on the complex formation of the analytes with the ammonium salt of O,O-diethyldithiophosphate (DDTP) and using the Amberlite XAD-

19. Participação dos canais de potássio no efeito relaxante do ácido ent-7a-hidroxitraquiloban-18-oico em traqueia isolada de cobaia / Participation of potassium channels in the ent-7a-hidroxitrachyloban-18-oic acid relaxation effect on guinea pig trachea
From Xylopia langsdorfiana A. St-Hil. &Tul. stem bark was isolated the diterpene of trachylobane class, ent-7α-hydroxytrachyloban-18-oic acid (trachylobane-318) that in previous studies showed to be able to relax guinea-pig trachea pre-contracted by carbachol (CCh). Thus, we aimed to investigate the action mechanism underlying in this trachylobane-318 r

20. Dynamics of sward condition and botanical composition in mixed pastures of marandugrass, forage peanut and tropical kudzu
This study was carried out to evaluate the dynamics of sward condition and botanical composition of a mixed pasture of marandugrass (Brachiaria brizantha cv. Marandu), forage peanut (Arachis pintoi cv. Mandobi) and tropical kudzu (Pueraria phaseoloides), rotationally stocked at four daily forage allowance levels (6.6, 10.3, 14.3 and 17.9% of live weight).

21. Manejo do mofo branco (Sclerotinia sclerotiorum L.) em tomateiro industrial / Management of white mold (Sclerotinia sclerotiorumL.) in tomato industry
Brazil ranks ninth in the world production of tomato (Solanum esculentum L.), while much of this production is destined for processing industries. The added value obtained with the fruit processing endorses this species as the vegetable with the greatest economic importance in the Cerrado region of Brazil, where the State of Goiás stands out as the largest

23. Padrão de germinação de sementes e estabelecimento de mudas de guanandi (Calophyllum brasiliense Cambess.)
CHAPTER II: Calophyllum brasiliense Cambess. is a tree, typical of tropical rainforests, with seed germination variable and uneven due to restrictions of the layers of the integument. The objective was to characterize the dormancy of seeds of species by their ability to soak, germination, emergence, distribution of germination over time and the timing and qu

24. Influence of the hydrolysis and condensation time on the preparation of hybrid materials
This work describes the hydrolytic sol-gel synthesis of silica particles prepared by a modified Stöber route, using the organofunctionalized alkoxide 3-methacryloxypropyl trimethoxysilane and tetraethylorthosilicate. The silica particles were obtained through basic catalysis from a mixture of precursor alkoxides, water, and isopropyl alcohol. Samples were p
