1. Collector mixtures and their synergistic effect on quartz floatability
Abstract Sinergy is the interaction of two or more agents to produce a combined effect greater than the sum of their separate effects. Etherdiamine yields superior results for quartz floatability in a Hallimond tube and higher selectivity in the reverse bench scale cationic flotation of an iron ore, when compared to ethermonoamine. Blending these collectors

2. Effects of granule particle size and lubricant concentration on tablet hardness containing large concentration of polymers
ABSTRACT The objective of this research work is to demonstrate the impact of granule size and lubricant concentration on the hardness of tablets in formulations containing higher concentration of polymers and to resolve the hardness issue during compression process. The work involves optimization of a milling process for size reduction of granules and blendi

3. Combination of Propylene Glycol Alginate and Lauric Acid on Water Retention and Mechanical Properties of Soy Protein Isolate-Based Films
The water sorption, water barrier properties and mechanical behavior of soy protein isolate (SPI) based films combined with propylene glycol alginate (PGA) and lauric acid (La) via a direct- or co-dried blending process were investigated. Higher water retention ability and a single glass transition temperature (Tg) were found when the PGA was added to form d

4. Starch/poly (butylene adipate-co-terephthalate)/montmorillonite films produced by blow extrusion
This study aims to prepare biodegradable films from cassava starch, poly (butylene adipate-co-terephthalate) (PBAT), and montmorillonite (MMT) using blow-extrusion process and analyze the effects of different types and concentrations of MMT on the microstructure, physicochemical, and mechanical properties of the resulting films. The films were produced by bl

5. Steel corrosion assessment by electrochemical impedance on metakaolin blended mortars
Since Corrosion of reinforcing steel in concrete is the cause of major economic losses, Portland cement has been traditionally replaced by cements blended with pozzalanic materials, most of which have been found to reduce the corrosion of steel. This paper shows the results of an experimental research aimed to investigate the corrosion of reinforcement in mo

6. Thermal & morphological evaluation of linear and radial SEBS-polypropylene blends
Blending of two or even more immiscible polymers is a very useful method to obtain new polymeric materials with ordered and tailored properties. Thermoplastic elastomers (TPE's) are interesting materials for various applications, including the automotive industry, due to their excellent balance between processability and physical properties, especially using

7. Mesclagem conceptual e compressão de relações vitais: a construção de objetos-de-discurso e negociação de sentidos em língua inglesa.
Considering the hypothesis that English language learners at the learning moment negotiate and share collective or individually meaning during the conversation, we intend, in this study, to analyze which are the linguistics and cognitive processes involved in the English meaning construction. According to the Blending Theory (Fauconnier &Turner 1998, 2002) a

8. Passagens / Passagens
Passages refers to transition, displacement, change, transmission and continuity. Perception of the body as a whole in the action of making; the movement and its resonances in connection with breathing and how this is transmitted in modeling the pieces. If passages here means relating differences, something that occurs somewhere between the being and the mat

9. Production and characterization of poly-3-hydroxybutyrate from crude glycerol by Bacillus sphaericus NII 0838 and improving its thermal properties by blending with other polymers
The aim of this work was to study the production of poly-3-hydroxybutyrate (PHB) under nitrogen limited conditions by Bacillus sphaericus NII 0838 using crude glycerol from biodiesel industry as sole carbon source. Effect of various process parameters on PHB production such as glycerol concentration, inoculum size and pH of the medium were optimized. Charact

10. Nanocompósitos de PVC, argila organicamente modificada e óxidos metálicos : estudo do processo de preparação e propriedades de combustão e emissão de fumaça / PVC, organically modified montmorillonite and metallic oxides nanocomposites : evaluation of the preparation process and fire and smoke behavior
Poly(vinyl chloride) (PVC), copper (II), molybdenum and zinc oxides, and organically modified montmorillonite nanocomposites were prepared in a melt blending intercalation process. The morphology of the nanocomposites was evaluated using X-ray diffractometry (XRD) and transmission electron microscopy (TEM), and indirectly by the increment of the Young modulu

12. Otimização no planejamento agregado de produção em indústrias de processamento de suco concentrado congelado de laranja
This work aim at developing models using linear programming, goal programming and robust optimization to support decision making in the frozen concentrated orange juice planning process. The proposed model includes orange harvesting plan, which takes into account oranges maturation curves. This fact leads to a model that incorporates a large portion of the s
