1. DESAFIO NA ESCOLHA DOS SOLVENTES EM SÍNTESE - O WORKUP COMO EXEMPLO
A procedure for the assessment and optimization of the greenness of solvents in synthesis was developed. It involves two optimization components, aiming at the optimization of both the intrinsic greenness of the solvents and their efficiency to improve the overall green performance of the synthesis, evaluated with mass, energy and time greenness metrics. The

2. Crosslinking starch/oat hull mixtures for use in composites with PLA
Abstract Modification of composite components has been proposed as a tool to improve their functional properties. The present work studied crosslinking of a starch/oat hull mixture by reactive extrusion with sodium trimetaphosphate (STMP), for application in composites with polylactic acid (PLA). The treated mixture was characterized regarding degree of subs

3. NUMERICAL AND COMPUTATIONAL ASPECTS OF COSMO-BASED ACTIVITY COEFFICIENT MODELS
ABSTRACT In the present work, some numerical and computational aspects of COSMO-based activity coefficient models were explored. The residual contribution in such models rely on the so called self-consistency equation. This equation does not have a closed-form solution and is usually solved by the successive substitution method. The performance of a classica

5. Substitution of soybean meal for urea in diets based on deferred buffelgrass hay for feedlot sheep
ABSTRACT The objective of this study was to evaluate the effect of substituting soybean meal for urea in diets based on deferred buffelgrass on the performance of feedlot sheep. Thirty mixed-breed sheep with an average initial body weight of 17±1.5 kg were distributed in a completely randomized design in which the experimental treatments consisted of five d

6. Study and Assessment of the Efficiency of the Cocoa Bark Extracted from the Theobroma Cacao as an Inhibitor of the Corrosion of Carbon Steel in Substitution of Benzotriazole
Corrosion represents high losses to the economy, therefore, researches on the minimization of its damages in materials, mainly the metallic ones, are necessary. Among the various alternatives of protection against corrosion, there is the application of corrosion inhibitors that can minimize or even stop the corrosive process of metallic materials. However, a

7. CARACTERÍSTICAS FISICOQUÍMICAS DE LA GRASA DE SEMILLA DE VEINTE CULTIVARES DE MANGO (Mangifera indica L.) EN COLOMBIA
ABSTRACT In the present investigation was evaluated yield extraction and some physicochemical properties of seed fat for 20 mango (Mangifera Indica L.) cultivars in Colombia. Seeds of mature fruit were processed in flour and were obtained the following composition: fat 6.73 % - 11.8 %, protein 4.3 % - 6.9 %, raw fiber 2.6 % - 6.1 % and ash 2.12 % - 3.9 %. T

8. Characterization of biomasses from the north and northeast regions of Brazil for processes in biorefineries
Abstract In search for renewable energy sources, the Brazilian residual biomasses stand out due to their favorable physical and chemical properties, low cost, and their being less pollutant. Therefore, they are likely to be used in biorefineries in the production of chemical inputs to substitute fossil fuels. This substitution is possible due to the high con

9. Thermal properties of chipboard panels made of sugar cane bagasse (Saccharum officinarum L)
The sugar cane bagasse is the most abundant agricultural residue produced in Brazil. It can be used for the production of chipboard panels and as constructive components for several types of environments. The substitution of timber for the bagasse minimizes environmental impacts and contributes to the generation of a new product with lower density and lower

10. Performance and carcass traits of Santa Inês lambs finished with different sources of forage
The objective of this study was to evaluate performance and biometrics of lambs fed different sources of forage. Twenty-four six-month-old Santa Inês female lambs were randomly allocated to four experimental diets and housed in individual stalls. They weighed on average 26.35±0.20 kg. The diets were coast cross hay (HAY), cassava hay (CAS), dehydrated by-p

11. Performance and isotopic composition of 13C and 15N in muscle tissue of Nile tilapia (Oreochromis niloticus) fed with different protein / Desempenho produtivo e composição isotópica de 13C e 15N no tecido muscular de tilápia do Nilo (Oreochromis niloticus) alimentada com diferentes fontes protéicas
Alternative sources of food have been studied in substitution for fishmeal in aquaculture, and it may result in a difference in incorporation of carbon and nitrogen, depending on the nutritional value and availability of the source. Two experiments were designed to quantify the participation of different protein sources in the muscle tissue in juvenile and p

12. Reformulação do perfil lipídico de produto cárneo emulsionado adicionado de óleo de linhaça e ervas e especiarias : avaliação das características físico-químicas e sensoriais / Reformulation of the lipid profile of emulsified meat product with the addition of linseed oil and herbs and spices : evaluation of the physico-chemical and sensory
The development of food products with healthier properties is one of the more relevant current, favored by new nutritional guidelines for nutrition and changing habits of consumers. The reformulation of lipid meat products implemented by the use of substitute components to saturated fat in this context has been the subject of many investigations. Thus, the a
