1. Mathematical Modeling of the Transesterification Reaction by Finite Elements: Optimization of Kinetic Parameters Using the Simplex Sequential Method
The use of biodiesel as fuel has been presented as a viable alternative in the search for renewable energies. It can be produced from the transesterification reaction of vegetable oils with methanol in the presence of sodium or potassium hydroxide as catalysts. In the present research, the transesterification reaction of soybean oil was modeled considering t

2. Structural reliability model considering mixed probabilistic and interval variables
Abstract Traditional probability-based structural reliability analysis method can only consider random uncertainties described by random distribution functions, which required sufficient experimental samples. On comparison, interval uncertainties can be more appropriate when lacking information. In realistic situations, several structural reliability models

3. Isolation and characterization of a human cementocyte-like cell line, HCY-23
Abstract Cementum is the mineralized tissue covering the tooth root that functions in tooth attachment and post-eruptive adjustment of tooth position. It has been reported to be highly similar to bone in several respects but remains poorly understood in terms of development and regeneration. Here, we investigate whether cementocytes, the residing cells in ce

4. Isolation of biologically active peptides from the venom of Japanese carpenter bee, Xylocopa appendiculata
Abstract Background Mass spectrometry-guided venom peptide profiling is a powerful tool to explore novel substances from venomous animals in a highly sensitive manner. In this study, this peptide profiling approach is successfully applied to explore the venom peptides of a Japanese solitary carpenter bee, Xylocopa appendiculata (Hymenoptera: Apoidea: Apida

5. Fitting equation of state parameters in parallel computers
This work compares two strategies to fit parameters of equations of state in parallel computers, emphasizing solutions that require few changes to existing sequential programs. One strategy uses the conventional Nelder-Mead algorithm coupled with parallel objective function evaluation (SSPO). The other strategy uses a parallel Nelder-Mead algorithm coupled w

6. Estratégias de computação seqüenciais e paralelas sobre espaços coerentes / Sequential and parallel computational strategies of coherence spaces
As estruturas de dados concretas (cds) são quaternas (C, V, E, l-) que contêm um conjunto C de células, um conjunto V de valores, um conjunto E de eventos e uma relação de habilitação l-. O conjunto de estados de uma cds é um domínio concreto que pode ser considerada a parte "abstrata" das cds. Da mesma maneira tem-se que os domínios de eventos (qu

7. PRÁTICAS SEQUENCIAIS DE NEGOCIAÇÃO EM INTERROGATÓRIOS POLICIAIS DA DELEGACIA DE REPRESSÃO A CRIMES CONTRA A MULHER
This dissertation will attempt to describe sequential practices of negotiation led by the police officer in the police inquiries at an All-Female Police Station. The methodological and theoretical references to map the practices sequentially are based on the Conversation Analysis Ethnomethodology. The sequential practices of negotiation were organized in ser

8. Ambiente computacional paradesenvolvimento de aplicações de controladores lógicos programáveis baseado em linguagens SFC e ST
This work proposes an environment for programming programmable logic controllers applied to oil wells with BCP type method of artificially lifting. The environment will have an editor based in the diagram of sequential functions for programming of PLCs. This language was chosen due to the fact of being high-level and accepted by the international standard IE

9. Descrevendo e analisando os textos escritos de língua portuguesa que compõem as unidades dos materiais didáticos dos cursos a distância
The purpose of this study was to analyse the texts that compound the material used in distance education courses presenting their regularities according to infrastructure, in order to characterize them as a textual genre. To do so, we are aimed at: a) describing and analysing the texts in relation to the organization of the thematic content (general plan); b

10. Competitive biosorption of nickel and copper ions on alginae and algae Sargassum filipendula / Bioadsorção competitiva dos ions niquel e cobre em alginato e alga marinha Sargassum filipendula
Environmental biotechnology studies have been conducted using alternative materials in order to eliminate heavy metal ions from industrial effluents. Brown algae are an attractive materials, due to their large availability and their reduced participation in the vital functions of marine ecosystems. The main structural polysaccharide of the brown algae is alg

Aplicação de uma nova proposta de discretização das equações Griffin-Wheeler-Hartree-Fock na geração de bases Gaussianas para cálculos de átomos e moléculas / Aplication of a new proposal for the discretization of the Griffin-Wheeler-Hartree-Fock equations in the generation of Gaussian leases for atomic and molecular calculations
The ongoing evolution of computers has led to several changes in the way of doing science, to create a multitude of new options for solving scientific problems. The implementation of computational methods allowed the theoretical treatment of large systems, complex and different areas of science. One area of particular focus and chemistry of molecules, now ca

12. Padronização da expressão heterologa e de modelo de ensaio de atividade para a proteina quinase humana S6K / Standardization of the heterologous expression and of a model assay of activity for the human protein kinase S6K
The 70kDa ribosomal S6 protein kinase 1 (S6K1) is a phosphoprotein involved in the regulation of genes related to translational control in mammals. S6K1 shows distinct nuclear (a1) and cytoplasmic (a2) forms. Phosphorylation of the S6K1 best characterized target, the protein of the small ribosomal subunit (RPS6), has been generally associated to the selectiv
