1. Carbon dioxide/methanol conversion cycle based on cascade enzymatic reactions supported on superparamagnetic nanoparticles
ABSTRACT The conversion of carbon dioxide into important industrial feedstock is a subject of growing interest in modern society. A possible way to achieve this goal is by carrying out the CO2/methanol cascade reaction, allowing the recycle of CO2 using either chemical catalysts or enzymes. Efficient and selective reactions can be performed by enzymes; howev

2. Caracterização cromatográfica de compostos orgânicos presentes nos resíduos sólidos provenientes de indústria de reciclagem de papel e sua aplicação na produção de briquetes de carvão vegetal
Recycling of paper in industrial scale has become an established practice worldwide. In this work, organic compositions of three different kinds of sludge generated in recycle paper industry were studied, and the incorporation of one of those sludge in briket was also investigated. The characterization of organic compounds in sludge samples and briket was pe

3. Treatment of welding electrode manufacturing plant wastewater using coagulation/flocculation-nanofiltration as a hybrid process
High water consumption and water scarcity make industrial wastewater reuse necessary, especially in those industries characterized by polluted effluents such as welding electrode manufacturing industries. The present paper investigates the coupling of coagulation-flocculation with nanofiltration (NF) to recycle water and reuse it in the process. First, the e

4. Antagonismo entre leveduras e bactérias láticas na fermentação alcoólica / Antagonism between yeasts and lactic acid bacteria in alcoholic fermentation
This study aimed to evaluate the antagonism between yeasts and contaminating bacteria of the ethanol production process with different metabolisms (homo- and heterofermentative) in different conditions. Thus, the fermentation performance of Saccharomyces cerevisiae strains used in industrial fermentation (BG-1, CAT-1, PE-2 and Fleischmann) was analyzed in co

5. Estudo do processamento do combustível UO2-7%Gd2O3 via mistura mecânica com reutilização de rejeitos do processo de fabricação e aditivo de densificação / UO 2 -7%Gd 2 O 3 FUEL PROCESS DEVELOPMENT BY MECHANICAL BLENDING WITH REPROCESSING OF WASTE PRODUCTS AND USAGE OF DENSIFICATION ADDITIVE
In the nuclear fuel cycle, reprocessing and storage of "burned" fuels, either temporary or permanent, demand high investments and, in addition, can potentially generate environmental problems. A strategy to decrease these problems is to adopt measures to reduce the amount of waste generated. The usage of integrated burnable poison based on gadolinium is a me

6. Behavior of industrial strains of Saccharomyces front inhibitory compunds present in sugarcane molasses in the production of biothenol / Comportamento de linhagens industriais de Saccharomyces frente a compostos inibitorios presentes no melaço de cana-de-açucar na produção de bioetanol
The general objective of this project was the evaluation of the effects of some organic substances present in molasses, sugar cane on strains of yeast for industrial use. Chapter I refer to a brief introduction and history of alcoholic fermentation. In Chapter II, samples of industrial molasses were examined, from 10 units producing sugar, located in the sta

7. Reuso de agua em industria de reciclagem de embalagens plasticas : aspectos economicos e ambientais em modelo de escala real / Water reuse on plastics recycling pack industry : economical and enviromental aspects in real scale model
The discussion about technical, economical and environmental feasibility of water reuse in industrial process has been a constant concern. This thesis purposes a simplified alternative for waste water treatment seeking reuse in a plastic recycle industry. The water, in this case, is a prime component because it is the main element for the debris and impuriti

9. CONTRIBUIÇÃO AO ESTUDO DAS PROPRIEDADES MECÂNICAS E DA DURABILIDADE DE CONCRETOS COM ESCÓRIA DE ACIARIA ELÉTRICA (EAF) COMO AGREGADO GRAÚDO / CONTRIBUTION TO THE STUDY OF MECHANICAL PROPERTIES AND THE DURABILITY OF CONCRETE WITH SLAG OF Residue (EAF) as aggregate
The increasing demand for aggregate for uses in engineering stimulated the search for alternative materials. In this way, the civil construction potentially started to be a great consumer of residues from other industries, becoming a great recycle plant. The use of by-product, brings great environmental benefits in relation to the degradation of the environm

10. Resposta ao estresse Ãcido em leveduras da fermentaÃÃo alcÃolica industrial
Fuel-ethanol fermentation process includes a continuous recycle of the yeast biomass, with yeast cell being exposed to low pH values. It promotes acidic stress that leads to a decrease in cell viability. The aim of his work is to study the factors responsible for cell resistance to acid stress from the identification of yeast gene that are responsive to this
