13. Avaliação do efeito de implantes subgengivais do polímero ELVAX com equistatina. Estudo microscópico em dentes de ratos extraídos e reimplantados / Evaluation of the effect of subgingival implants of polymer ELVAX with echistatin: microscopic study on rats\ extracted and reimplanted teeth
This study aimed to microscopically investigate the effect on the dental resorptive process of subgingival implants of ELVAX polymer with peptide echistatin in reimplantation of upper incisors in rats. For this purpose, 42 animals were used and divided into groups with and without echistatin. Extra alveolar socket period was 30 and 60 minutes and post-surgic

14. The fundamental elements in certain inverse acoustic problems: their roles and interactions
Acoustic holography and holophony, wave field synthesis and active noise control are based on common elements which are causality, model, objective, and regularization. In the frequency domain (putting causality aside), a simple formulation states the influence - not the interaction - of errors of the model and objective and of regularization of the results.

15. MANAGEMENT MODEL IN THE EBX GROUP COMPANIES: AN ASSESSMENT WITH THE STRATEGIC PLANNING / O MODELO DE GESTÃO DAS EMPRESAS DO GRUPO EBX: UMA AVALIAÇÃO DO EFETIVO ALINHAMENTO AO PLANEJAMENTO ESTRATÉGICO
This work aims to address management model, the interaction between the concepts of strategic planning, project management and portfolio management and understand how this interaction occurs in the EBX Group organizations. It also analyzes how the management reflects the direction outlined in the strategic planning of each company. Four propositions were est

16. FormulaÃÃo MatemÃtica para CÃlculo de VariaÃÃo de ConcentraÃÃo em Escoamento EstacionÃrio / Mathematical Formulation For The Calculation Of Changes Of Concentration In Stationary Flow.
The main aim of this research is to evaluate a variation of concentration between the affluent and effluent in a biophysical or physicochemical system. The theoretical system of references used here was based upon a differential equation of steady flow, involving a chemical kinetics and a longitudinal dispersion, in which there is a number of sufficiently lo

17. Análise qualitativa e quantitativa de compostos de borracha destinados à fabricação de revestimentos de embreagem / Qualitative and quantitative analysis of rubber compounds destined for clutch facings manufacture
In this work it was developed a methodology for qualifying and quantifying rubber compounds destined for facings manufacture. These compounds are formed by a large number of components which use, beyond the elastomeric base, a resin that is used as a process agent, vulcanization agents and different fillers, each one with a specific function. The elastomeric

18. Comparison of two methods for alveolar bone loss measurement in an experimental periodontal disease model in rats
There are many studies that evaluate possible risk factors for periodontal diseases in animals. Most of them have focused only on the biological aspects of disease occurrence; therefore, it has been difficult to compare studies of the different methodological approaches. The aim of the present study was to compare different methods - linear and area - of the

20. Modelo experimental para pesquisa de linfonodo sentinela no penis do cÃo / Identification of sentinel lymph of inguinal region in dogs Model
Cancer of the penis is a rare neoplasm in developed countries, but troubling in the countries of Latin America, Asia and Africa. In Brazil represents about 2% of male malignancies. Considering this incidence is estimated for 2010 some 160 new cases in CearÃ. Because there is a scarcity of publications on this disease, there are still numerous issues in thei

21. E tenho dito: a gramaticalizaÃÃo e a variaÃÃo do pretÃrito perfeito composto em narrativas dos sÃculos XV a XVII / And I have said: The grammaticalization and the change in past tense compound in narratives in century XV - XVII
In this dissertation, we deal with the grammaticalization of past tense compound in Portuguese. We discuss linguistic change, based on the correlation form(s)-function(s) in two lines of analysis: (I) the grammaticalization continuum of to have/there to be (full) + adjectival participle >to have/there to be (auxiliary) + verb participle and (ii) the linguist

22. Teoria palco-platéia: a interação entre regulação e autorregulação do mercado de bolsa / Stage-audience theory: interaction between regulation and self-regulation of the exchange market
The thesis to be defended is that the institutionally structured self-regulation and legitimized by the regulation, is an efficient array to treat flaws and risks inherent of the exchange market. The paper begins with a description of the current self-regulation structure of the exchange market, highlighting its new institutional format, due to the demutuali

23. Bianchi type I tilted cosmological model for barotropic perfect fluid distribution with heat conduction in general relativity
Bianchi Type I tilted cosmological model for barotropic perfect fluid distribution with heat conduction is investigated.To get the deterministic solution, we have assumed barotropic condition p = γ ∈ ,0 < γ < 1, p being isotropic pressure, ∈ the matter density and a supplementary condition between metric potentials A, B, C as A = (BC)n where n is the c

24. NONLINEAR DYNAMICS, INSTABILITY AND CONTROL OF STRUCTURAL SYSTEMS WITH MODAL INTERACTION / DINÂMICA NÃO-LINEAR, INSTABILIDADE E CONTROLE DE SISTEMAS ESTRUTURAIS COM INTERAÇÃO MODAL
The aim of this thesis is to study the influence of coupled buckling modes on the static and particularly on the nonlinear dynamic behavior of structural components liable to buckling. For this, two discrete two degrees of freedom models known for their complex nonlinear behavior are selected: the well-known Augusti¿s model and a simplified model of cable-s
