1. Estimativa do potencial de recuperação energética de resíduos sólidos urbanos usando modelos matemáticos de biodigestão anaeróbia e incineração
RESUMO Atualmente, um dos grandes problemas enfrentados pelos gestores de resíduos sólidos urbanos (RSU) é a disposição final dos resíduos gerados por sua população. As disposições de resíduos devem ser feitas em espaços e sob condições adequados de modo a minimizar os impactos socioeconômicos e ambientais. Nesse contexto, este artigo teve por

2. Modelagem e propriedades termodinâmicas da secagem de fatias de acuri
Resumo O acuri é uma fruta pouco explorada industrialmente, mas com grandes perspectivas e possibilidades de uso. Para tanto, torna-se necessário reduzir o seu teor de água, aumentando então a sua vida útil, o que possibilitará sua utilização em mercados distantes dos locais de produção. Nesse sentido, objetivou-se secar fatias de acuri, com espes

3. A GENERIC TACTICAL PLANNING MODEL TO SUPPLY A BIOREFINERY WITH BIOMASS
ABSTRACT The supply chains which bring biomass to biorefineries play a critical role in biofuel production. Optimization models can help decision makers to design more efficient chains and minimize the cost of biomass delivered to the refineries. This article based on a French national research project on biomass logistics considers one refinery, able to pro

4. Online hybrid modeling method with application for predicting Bauxite production indicators
Abstract In the bauxite flotation process, concentrate grade and tailings grade are key production indicators; however, they are difficult to measure online. It is also difficult to develop an effective mathematical model for the process because of the complex non-linear and uncertain relationship among the feed parameters (feed grade, pulp density, slurry p

5. Inovações na produção de hidrolisados de soja : modelagem e análise econômica de processo
Soybean and its derivatives have the desired properties for food either for humans or various animals because of its high protein content, which is associated to a good balance of amino acids. However, when the protein is hydrolyzed into smaller peptides, the nutritional value can increase further. A product with high nutritional value added but which does n

6. Study on fermentation conditions of palm juice vinegar by response surface methodology and development of a kinetic model
Natural vinegar is one of the fermented products which has some potentiality with respect to a nutraceutical standpoint. The present study is an optimization of the fermentation conditions for palm juice vinegar production from palm juice (Borassus flabellifer) wine, this biochemical process being aided by Acetobacter aceti (NCIM 2251). The physical paramete

7. Decision support bioeconomic model for livestock systems / Modelo bioeconômico para suporte à decisão em sistemas pecuários
Rural managers make decisions in uncertain and dynamic environments. These characteristics, associated with bounded rationality can lead to the formulation of mental models that reflect reality in a distorted way. In this context, the procedures for modeling and simulation are important tools to understand how the production systems operate and to make decis

8. Powder mombin (Spondias mombin L.) atomized: Physical, physicochemical and sensory evaluation of the hygroscopic behavior / Pà de cajà (Spondia mombin l.) atomizado: caracterizaÃÃo fÃsicas, fÃsico-quÃmicas, sensoriais e avaliaÃÃo do comportamento higroscÃpico
The hog plum is a fruit that has good physical-chemical and sensory properties, which give it great acceptance by consumers and industry, and presents excellent nutritional quality. It has sugars, vitamin A and C. In this context, this study aimed to apply the process of atomization in hog plum pulp, using two experimental designs, analyzing the process vari

9. Pão de forma sem glúten a base de farinha de arroz / Gluten free pan bread based on rice flour
It is being a challenge for researchers in the food field to make available to the celiac the variety of foods that they are not allowed to consume. The bread has been studied as deep in it, especially the replacement of the technological functionality of gluten, which is particularly nontrivial. The objective of this work was to develop gluten-free bread ba

10. Modelos de simulação e suas possíveis aplicações no estudo econômico do biodiesel.
This paper introduces the system simulation technique and looks for potential application in the biodiesel agribusiness. The simulation basics are presented. It's described the components of a simulation model, the models classification and the model construction process. Some uses in decision making and agricultural problems are shown. The decision making m

11. Simulação da dinâmica de carbono em bacias hidrográficas
In most aquatic ecosystems respiration exceeds autochtonous gross primary production leading to a negative net ecosystem production. Recent studies attributes this condition to allochtonous organic matter degradation processes, so the inland water carbon cycle should be linked to the input of organic carbon from the catchment. This work contributes to a bett

12. Estudo da cinética e do equilíbrio da adsorção da cefamicina C em resina de troca iônica e simulação do processo contínuo
The cephamycin C (CefC) is a beta-lactam antibiotic produced from submerged and aerated cultures of Streptomyces clavuligerus. Acts as inhibitor of cell wall formation of Gram-negative bacteria and is resistant to the hydrolytic action of betalactamases enzymes. The literature presents few scientific results published regarding the purification of CefC, and
