3. Agricultural tractor performance fueled with proportions of biodiesel
ABSTRACT Among the fuel sources used nowadays, biofuels stand out for being renewable and biodegradable. In this sense, this work aimed to evaluate the performance and smoke opacity of an agricultural tractor in soil tillage activities, depending on the biodiesel blends and the engine rotation. Were used six blends of soy (S) and murumuru (M) biodiesel and s

4. The importance of education
Abstract The present research is dedicated to analyzing the addition of sawdust biomass, which is a carbonaceous raw material that may be used in coal blends for the production of metallurgical coke, preserving the required quality, with lower cost. The quality of metallurgical coke may be determined by the efficiency of its chemical, physical and thermal fu

6. Quality properties of doughs and noodles using chayotextle (Sechiem edule) flours
Abstract The quality and physicochemical properties of dough and noodles made from blends of chayotextle flour and wheat semolina were investigated. The results showed that the inclusion of chayotextle flour increased both the hardness and adhesiveness of the dough, and there was a 10% increase in cohesiveness and elasticity when using this particular flour.

7. Gluten-free cookies from sorghum and Turkish beans; effect of some non-conventional and commercial hydrocolloids on their technological and sensory attributes
Abstract Consumption of gluten-free products is the best possible option for patients with celiac disease. The development of gluten-free cookies may provide a suitable alternative for individuals who are gluten-intolerant. The purpose of this research was to assess the use of hydrocolloids as gluten substitutes in cookies. Commercially available (gum Arabic

8. Isotopic Analysis of Sugarcane/Petroleum Polyethylene Blends: A Perspective on the Application of Stable Isotope Method (δ13C)
In the present work, we propose the application of stable isotope analysis (δ13C) as an auxiliary tool for the inspection of sugarcane/petroleum polyethylene blends. Our results are supported from the analysis of selected samples by accelerator mass spectrometry (14C-AMS). From the results, it was concluded that the δ13C method is suitable to discriminate

9. CARACTERIZAÇÃO FÍSICA E QUÍMICA DA BIOMASSA USADA COMO COMBUSTÍVEL SÓLIDO EM UMA CALDEIRA
Biomass is a renewable energy source most used in the world, however, depending on the chemical properties and origin of the material used as biofuel, the amount of ash generated during combustion can be high, harming the energetic harnessing. The objective of this study was to characterize chemically and physically biomass: bark, sawdust, and urban pruning;

10. OXIDATIVE STABILITY AND COLD FILTER PLUGGING POINT OF BIODIESEL BLENDS DERIVED FROM FATS AND SOY OIL
Biodiesel made from oils is rich in polyunsaturated fatty acids methyl esters, and, consequently, presents high tendency to oxidize. Biodiesel made from fats, on the other hand, is mainly comprised by saturated chains. Although it is highly stable, they easily crystalize at low temperatures. Blends from both can exhibit optimized properties. In this work, ox

12. Influence of the addition of KCl and CaCl2 blends on the physicochemical parameters of salted meat products throughout the processing steps
Abstract The objective of this study was to evaluate the effects of different chloride salts (NaCl, KCl, and CaCl2) on the characteristics of salted meat products through the determination of moisture, pH, aw, chloride, ash levels, cooking loss, and instrumental color during the processing steps. Four salted meat treatments were elaborate using the following
