1. Obtenção de scaffolds bioabsorvíveis a partir de blenda de PLGA e IR com adição de hidroxiapatita
RESUMO A obtenção de scaffolds bioativos a partir da blenda polimérica de poli (ácido láctico-co-glicólico) (PLGA) e poliisopreno (IR) com diferentes adições de Hidroxiapatita (HAp) é proposta como uma alternativa à engenharia de tecidos. Para o preparo das soluções poliméricas, a blenda de PLGA/IR e a HAp foram dissolvidas em clorofórmio. Post

2. RELIABILITY-BASED MULTI-OBJECTIVE OPTIMIZATION APPLIED TO CHEMICAL ENGINEERING DESIGN
ABSTRACT Chemical engineering optimization represents a significant challenge due to the complexity of the mathematical models that are frequently required in this area. These models are normally associated with nonlinear equations that represent mass, energy, and momentum balances, which are submitted to physical, constitutive, environmental, and design lim

4. Damage evaluation and failure mechanism analysis of steel tube confined reinforced-concrete columns by acoustic emission technology
Abstract As a new kind of composite structures and its advantages, the using of steel tube confined reinforced concrete (STCRC) columns have received increasing attention in civil engineering. Acoustic emission (AE) technique is applied to monitor the damage process of STCRC columns during an uniaxial compression test. The aim of this study is to investigate

5. Feasibility Study through Grid-Connected Photovoltaic Systems in Curitiba
ABSTRACT The increase in energy demand in Brazil encourages the country to increasingly invest in generation of electric energy, where the demand for other renewable sources increases gradually because they have a lower impact on the environment. The use of Grid-Connected Photovoltaic Systems (GCPVS) is a viable solution for the country, since it presents fa

6. Low cost system to measure active power in electrosurgical units
Abstract Introduction: The real-time measurement of active power delivered to patients during the electrosurgical act is still an engineering challenge. Besides, there is no electrosurgical unit on the market capable of doing it according to the normative requirement. Methods This work presents the design of an electronic structure capable to probe the ele

7. Thermomagnetic Study for Identification of Mineral Phases
The characterization of materials is an area of extreme importance for engineering, it uses a range of instrumental techniques to provide an information bank for material analysis and selection. In the treatment of iron ore the mineralogical characterization is done, almost exclusively, by optical microscopy. However, materials with very fine granulometry, b

8. Influence of implant-abutment angulations and crown material on stress distribution on central incisor: a 3D FEA
Abstract Aim: To investigate the effect of implant-abutment angulation and crown material on stress distribution of central incisors. Finite element method was used to simulate the clinical situation of a maxillary right central incisor restored by two different implant-abutment angulations, 15° and 25°, using two different crown materials (IPS E-Max CAD

9. UMA ABORDAGEM OTIMIZADA PARA O PROBLEMA DE ALOCAÇÃO DE EQUIPES E ESCALONAMENTO DE TAREFAS PARA A OBTENÇÃO DE CRONOGRAMAS EFICIENTES / AN OPTIMIZED APPROACH TO THE PROBLEM ALLOCATION OF TEAMS AND SCALING OF TASKS FOR OBTAINING schedules EFFICIENT
In software development, as well as any other activity of a wide range of engineering, an effective project planning is essential. Failures in planning or poor planning can cause delays and costs that, given time and budget constraints, are often unacceptable, leading to critical failures in business. One of the main activities of project planning is the pla

10. Antecedentes da lealdade e da permanência de alunos em uma instituição de ensino superior
Analyze the antecedents of loyalty and permanence of students in undergraduate courses in an Institutions Higher Education (IES) is the goal of this research. To this it is proposed to test two theoretical models of the determinants of loyalty and permanence of students at university. The study design was descriptive method with quantitative, assess or surve

11. Economic analyses for the evaluation of is projects
Information system projects usually have numerous uncertainties and several conditions of risk that make their economic evaluation a challenging task. Each year, several information system projects are cancelled before completion as a result of budget overruns at a cost of several billions of dollars to industry. Although engineering economic analysis offers

12. Valor da informação incorporando flexibilidade operacional / Value of information incorporating operational flexibility
At the beginning of field development, many questions regarding the reservoir structural model still remain and it is necessary to mitigate this uncertainty and associated risk before the final field development plan proposition. Mitigation of risks and uncertainties can be done in two ways: through additional information acquisition and operational flexibil
