2. Production and extraction of clavulanic acid from Streptomyces spp. by extractive fermentation using aqueous two-phase system / Produção e extração de ácido clavulânico de Streptomyces spp. por fermentação extrativa utilizando sistemas de duas fases aquosas
Clavulanic acid (CA) is a potent inhibitor of β-lactamases used in the medical field. Alternative methods, economic and simple purification are of great interest. This PhD project aims to produce and extract clavulanic acid of Streptomyces spp. By extractive fermentation using aqueous two-phase system (ATPS) - Polyethylene glycol (PEG)/phosphate salts.

3. PROJETO DE POÇOS MULTILATERAIS EM RESERVATÓRIOS DE PETRÓLEO OTIMIZADOS POR ALGORITMOS GENÉTICOS / MULTILATERAL WELLS DESIGN IN OIL RESERVOIR THROUGH GENETIC ALGORITHMS OPTIMIZATION
One of the most important factors for recovering oil from oil reservoirs is the wells configuration. Now a days, on the industry, this process is conduced manually, where a specialist generates a few configuration options and uses the best one with best results. This work proposes to investigate a decision support system to optimize the wells¿ configuration

4. Application of herbicides to floating rate using predictive control / Aplicação de herbicidas a taxas variáveis utilizando controle preditivo
The objective of this project is to study a predictive controller for a herbicides injection system with variable rates where the herbicide and water are placed in different recipients and sent to a mixer. A strategy to generate the reference for the predictive controller characterizes the system as hybrid because there are two modes of operation for the her

5. Development of extruded profiles from high density polyethylene and wood flour composites / Desenvolvimento de perfis extrudados de compósitos de polietileno de alta densidade com farinha de madeira
Polymer profiles extrusion shows some peculiarity due to the flow behavior of these materials during the processing. On the other hand, the profile die design and tooling has been more a result of professionals expertise than an engineering project in essence. In the present work, it was aimed to combining concepts of computers aided engineering to rheologic

6. Otimização de risco estrutural baseada em confiabilidade / Reliability-based structural risk optimization
In a competitive environment, structural systems must be designed considering not only their function, but also their total costs of construction and operation and their ability to generate profit. The costs are directly linked to the risk resulting from construction and operation of the structure. Risk is defined as the product of failure cost by failure pr

7. As contribuições da percepção ambiental para os projetos urbanos :o caso da Vila Zumbi dos Palmares na Região Metropolitana de Curitiba
The informal portion of the cities is seen as a process which contrasts the traditional elements of urban planning. For this reason, it is understood that the studies concerning irregular occupations and ways of intermediating urban interventions have strong impact on urban management. It discusses therefore, how the incorporation of environmental perception

8. Expressão heteróloga do gene Hxyn2 do fungo Humicola grisea var. thermoidea em Pichia pastoris: Produção e purificação da enzima HXYN2r e aplicação em testes de panificação / Heterologous expression of the gene Hxyn2 fungus Humicola grisea var. thermoidea in Pichia pastoris: production and purification of the enzyme HXYN2r testing and application in bakery
Endoxylanases are the main group of enzymes involved in the hydrolysis of xylan. This enzymes have application in industrial proposes, like as drink, food, feed, clothes industries and for bleaching cellulose paper pulps. In bread making the xylanases have been used to improve processing and product quality of loaf, leading soft dough and loaf with larger vo

9. Caracterização bioquímica da endoxilanase recombinante (HXYN2r) do fungo termofílico Humicola grisea var. thermoidea e sua aplicação na sacarificação de resíduos agrícolas
Xylanases have been used in the biobleaching of paper pulps, in bioconversion of plant biomass, for food and feed industries, among others. For successful selection of xylanases suitable for specific industrial applications it is important to characterize enzymes isolated from different sources. The thermophilic fungus Humicola grisea var. thermoidea is desc

10. Définition et implémentation des corrections instrumentales de la mission spatiale CoRoT
CoRoT (Convection, Rotation and planetary Transits) is a space mission conceived to the stellar seismology and the search of extra solar planets. Both scientific programs are based on very high precision photometry and require long and uninterrupted observations. For the study of the stellar oscillations, the instrument must be able to measure periodic varia

11. Correlation between Indoor and Outdoor Human Thermal Preferences: A Study of the 55-2004 ASHRAE Standard Method / Relações entre preferências térmicas humanas no interior de edificações e as temperaturas externas: um estudo sobre o método adotado na norma AHSRAE 55-2004
Thermal comfort is specifically related to thermal behavior in response to both indoor and outdoor air temperature. Human thermal acceptability to climate changes and its effects depend on several aspects. It relies not only on local climatic conditions, but also on personal traits which can interfere seriously with thermal preferences as well as with someon

12. Método de Otimização Topológica em Estruturas Tridimensionais
The topology optimization problem characterize and determine the optimum distribution of material into the domain. In other words, after the definition of the boundary conditions in a pre-established domain, the problem is how to distribute the material to solve the minimization problem. The objective of this work is to propose a competitive formulation for
