1. MATHEMATICAL MODELLING AND SOLUTION APPROACHES FOR PRODUCTION PLANNING IN A CHEMICAL INDUSTRY
ABSTRACT This paper addresses a lot sizing problem in a Brazilian chemical industry where a product can be produced by more than one process, which can use different parallel machines and may even consume a wide range of raw materials. Moreover, most of the products are liquids and the inventories must be kept in a restricted number of storage tanks with a l

3. Rhamnolipid Biosurfactants Produced by Pseudomonas Species
ABSTRACT: Surfactants are chemical products widely used in our daily life in toothpaste and other personal hygiene and cosmetic products, and in several industries. Biosurfactants are surfactants of biological origin that can be produced by microorganisms and have many advantages, such as low toxicity and high biodegradability, compared to synthetic counterp

4. Utilization of molasses and sugar cane bagasse for production of fungal invertase in solid state fermentation using Aspergillus niger GH1
Agro-industrial wastes have been used as substrate-support in solid state fermentation for enzyme production. Molasses and sugarcane bagasse are by-products of sugar industry and can be employed as substrates for invertase production. Invertase is an important enzyme for sweeteners development. In this study, a xerophilic fungus Aspergillus niger GH1 isolate

5. Análise de simulantes para produtos ácidos acondicionados em embalagens metálicas / Analysis of simulants to acidic products conditioned in meal package
Tin-plate cans represent most of the cans for canned food. Since they are not inert, during the storage period, interaction occurs with the product and metal dissolution can occur, especially when it is acid food. To minimize this interaction it is used organic coatings, and epoxy-phenolic resin is the the most used. As the foods are complex biochemical syst

6. Identificação dos fatores críticos da colheita mecanizada de cana-de-açúcar (Saccharum spp.) / The identification of the critical factors of sugarcane (Saccharum spp.) mechanized harvesting
The sugar cane has significant role on Brazilian agribusiness economy. Its sub products are used for electric power generation, fuel production, as raw material for food and chemical industry. On sugarcane production, harvesting is considered as one of the most important operations of the process for it has to attend the raw material demanded by the sugar mi

7. Aplicações da celulose de palha de cana-de-açúcar: obtenção de derivados partindo de celulose branqueada e de biocompósitos com poliuretana obtida a partir de óleo de mamona (Ricinus communis L.) / Applications of sugarcane straw cellulose: obtainment of derivatives from bleached cellulose and biocomposites with polyurethane obtained from castor oil (Ricinus communis L.)
The sugarcane processing generates various agricultural byproducts such as bagasse and straw, which is considered one of the main waste generated due to the mechanization of the harvest in Brazil. Thus, the availability and composition of sugarcane straw have driven a great effort to develop technologies that provide its effective utilization. This study aim

8. Potential use of natural red mud as pozzolan for Portland cement
Red mud, the main waste generated in aluminum and alumina production by the Bayer process, is considered hazardous due to its high pH, according to the Brazilian standard NBR 10004/2004, and worldwide generation of this waste exceeds 117 million tons/year. In this work, non-calcined red mud was used, thus requiring less energy and time and reducing costs, wh

9. Produção de proteína animal de qualidade com sustentabilidade: controle racional das parasitoses dos bovinos.
In Brazil as in the rest of the world, sectors of production and commercialization of animal originated foods, are changing to attend the two highst marcket demands: competitivity and quality. These exigencies are specially related to healthy foods. So the use of products that leave residues in meat and/or milk is going to be more restritive in an animal pro

11. Recuperação hidrometalúrgica de metais da drenagem ácida de minas por precipitação seletiva
Acid mine drainage (AMD) is an important water pollution problem in coal production. The active treatment of AMD involves the addition of alkaline reagents to increase the pH and precipitate the dissolved metals as hydroxides. Although active treatment can provide effective remediation, it has the disadvantages of high operational costs and problems related
