1. Synthesis and Evaluation of Antibacterial Activity of 1,2,3-Triazole and Ether Derivatives of Paeonol
Multi-drug-resistant bacteria (MDR) are the cause of different infections and diseases that have affected humanity for a long time, and have been an emerging global health problem that has led to increased morbidity and mortality. The growing emergence of MDR bacteria has underlined the need for development and discovery of new antibacterial compounds. In th

3. Physicochemical, sensory properties and in-vitro bioaccessibility of phenolics and antioxidant capacity of traditional noodles enriched with carob (Ceratonia siliqua L.) flour
Abstract In this study, the use of carob flour (CF) was investigated to improve the nutritional, antioxidative, and sensory properties of the noodles produced by the traditional method. In traditional noodle production, carob flour was used as a substitute to wheat flour at six different ratios (0% -control: Cmilk, Cwater, 10-40%, CF; w/w). In the noodle sam

4. Synthesis of Antioxidant Additive from Safflower Seed Oil
Several published studies have evaluated the problems associated with the utilization of biodiesel obtained from safflower (Carthamus tinctorius L.) oil due to the low oxidative stability, caused by the high content of unsaturated fatty acids. Thus, this study aimed at the extraction of safflower seed oil and its use as an unsaturation source to obtain a syn

5. APROVEITAMENTO DE PRECURSORES LIGNOCELULÓSICOS PARA PRODUÇÃO DE ACETATO DE CELULOSE
The feasibility of obtaining cellulose acetate from lignocellulosic precursors is of great interest from the environmental, economic and technological points of view. Herein, sugarcane bagasse and vegetable sponge (Luffa cylindrica ) were used as precursors to produce cellulose using the organosolv extraction procedure. From the extracted celluloses, the pro

6. Evaluation of the Influence of the Substituting Cation on the Structural and Morphological Properties of the New Garnet Sm3−xREExFe5O12 (REE = Dy, Gd and Lu)
Rare earth garnets (REE3Fe5O12) have magnetic-electric and optical properties that can be used in transmitters, microwave and data storage devices. These properties depend mainly on partial or total substitution of the cationic sites, as well as by the synthesis method used. Therefore, in this work was studied the influence of the substituting cation on the

7. POLYETHERIMIDE/POLYVINYLPYRROLIDONE HOLLOW-FIBER MEMBRANES FOR USE IN HEMODIALYSIS
Abstract In this study, polyetherimide/polyvinylpyrrolidone (PEI/PVP) hollow fiber membranes (HFMs) were synthesized by the phase inversion method. The synthesized PEI/PVP membranes were characterized by morphological analysis and transport properties (hydraulic permeability and solute rejection coefficient). Their performance in uremic solutes separation wa

9. Síntese de perovskitas tipo LaAl1-xCrxO3 para aplicação em esmalte transparente
RESUMO No Brasil, estudos sobre pigmentos cerâmicos ainda são bastante escassos. Por esta razão, grande parte dos pigmentos consumidos pela indústria cerâmica são importados dos países europeus. Outra parte destes pigmentos são obtidos pela rota cerâmica, entretanto, esta rota de síntese resulta em pigmentos com propriedades bastante heterogêneas,

11. Partial substitution of fishmeal with soybean protein-based diets for dourado Salminus brasiliensis
ABSTRACT Cost and environmental restrictions limit the use of fishmeal (FM) in aquafeeds and plant protein (PP) sources. Soybean by-products are important alternative; however, their antinutritional factors may reduce fish growth. This study evaluates the effect of FM substitution for PP (soybean meal and soy protein concentrate) in diets of dourado (Salmi
