1. Incorporation of Fluorescent Dyes in Electrospun Chitosan/Poly(ethylene oxide)
Polymeric films have been increasingly investigated due to the ease of miniaturization and integration in several sensor devices. Films obtained from the electrospinning technique have a controlled diameter and homogeneity, and substances can be incorporated into the polymeric network. Electrospinning fiber of chitosan (Ch) and poly(ethylene oxide) (PEO) was

3. 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

4. Modeling of Variable Lamé's Modulii for a FGM Generalized Thermoelastic Half Space
Abstract In this work we consider a problem in the context of the generalized theory of thermoelasticity for a half space. The material of the half space is functionally graded in which Lamé's modulii are functions of the vertical distance from the surface of the medium. The surface is traction free and subjected to a time dependent thermal shock. The probl

5. Case depth in SAE 1020 steel using barkhausen noise
The most widely used thermochemical process for surface hardening of steels is case hardening. Using several different heat treatments, martensitic surface layers were formed on SAE 1020 steel into which carbon had been diffused. Case depths were measured by traditional destructive techniques. Barkhausen noise measurements were made and both the RMS Barkhaus

6. Fabricação e caracterização de sistemas poliméricos nanoestruturados obtidos por meio do usa da técnica de eletrofiação / Production and characterization of nanostructured polymer systems obtained by the use of electrospinning technique
The electrospinning process is known to be an efficient technique for the fabrication of polymer nanofibers. The nanofibers have great potential for application in various areas of technology such as sensors, catalysis, filtration systems and especially in the medical field in tissue engineering, controlled release of drugs, poultices for burns and other app

7. Optimization of particle bombardment parameters for the genetic transformation of Brazilian maize inbred lines.
The objective of this work was to develop a genetic transformation system for tropical maize genotypes via particle bombardment of immature zygotic embryos. Particle bombardment was carried out using a genetic construct with bar and uidA genes under control of CaMV35S promoter. The best conditions to transform maize tropical inbred lines L3 and L1345 were ob

8. A wavelet-based approach for analyzing industrial stochastic textures with applications
Several continuous manufacturing processes use stochastic texture images for quality control and monitoring. Large amounts of pictorial data are acquired, providing important information about both the materials produced and the manufacturing processes involved. However, it is often difficult to measure objectively the similarity among industrial stochastic

10. Intencionalidades e práticas na construção de metodologias o CEFET-SE / Intentions and practices in the construction of methodologies for the Secondary Teaching (designation in Brazil) of Professional Education in CEFET-SE
Successive curricular changes that occurred in professional education altered pedagogical practices, and these practices being developed by means of integrating projects, at Centro Federal de Educação Tecnológica de Sergipe (CEFET-SE), between 2001 and 2003, originated some questions which became the study object of this thesis. We search for theoretical

11. Application of direct tracking method for measuring electrospun nanofiber diameter
In this paper, direct tracking method as an image analysis based technique for measuring electrospun nanofiber diameter has been presented and compared with distance transform method. Samples with known characteristics generated using a simulation scheme known as µ-randomness were employed to evaluate the accuracy of the method. Electrospun webs of polyviny

12. ConstruÃÃo de cÃdigos de bloco lineares via transformadas digitais
New families of error-correcting codes, created from the Fourier number theoretic transform (Fourier Codes) and from trigonometric transforms over finite fields (FFCT-4e and FFST-4e Codes), are introduced in this dissertation. The code parity-check matrix, its dimension and minimum distance are obtained from the eigenstructure of the unitary Fourier number t
