1. Lithogeochemical and Nd-Sr isotope data of the orthogranulites of the Juiz de Fora complex, SE-Brazil: insights from a hidden Rhyacian Orogen within the Ribeira belt
Abstract New petrography, geochemistry and Sm-Nd and Sr data from the orthogranulites of the Juiz de Fora complex in southern Rio de Janeiro State and compiled information provide insights on the petrogenetic and tectonic evolution. The complex comprises several geochemical groups including mafic orthogranulites (three tholeiitic and one alkaline) and felsic

2. The Barreiro suite in the central Ribeira Belt (SE-Brazil): a late Tonian tholeiitic intraplate magmatic event in the distal passive margin of the São Francisco Paleocontinent
Abstract New geochemical, U-Pb, Lu-Hf and Sr-Nd data from the Barreiro Suite metabasites in comparison with enclaves within the distal Andrelândia Group and the orthogranulites of the Juiz de Fora Complex are presented. Geochemical data suggest intraplate setting, with high and low-TiO 2 , TDM Nd ages between 1.80 and 1.41 Ga, negative ΕNd t and ( 87 Sr/ 8

3. Rickettsia amblyommii infecting Amblyomma sculptum in endemic spotted fever area from southeastern Brazil
The Rickettsia bacteria include the aetiological agents for the human spotted fever (SF) disease. In the present study, a SF groupRickettsia amblyommii related bacterium was detected in a field collected Amblyomma sculptum (Amblyomma cajennense species complex) tick from a Brazilian SF endemic site in southeastern Brazil, in the municipality of Juiz de Fora,

4. Modelagem dos fenômenos de transporte termo-hídricos em meios porosos submetidos a temperaturas elevadas : aplicação a uma bicamada rocha-concreto
Concrete is an extremely complex material, whose properties are not yet fully understood. The diculties in describing and predicting the behavior of concrete structures are due to aspects related to the heterogeneity of medium - which is porous and multiphase - presenting uids in liquid and gas forms. When exposed to high temperature conditions, such diculti

5. Doce ou atroz, manso ou feroz‖: os currículos realizados/inventados na relação com a(s) diferença(s) no cotidiano escolar
It was from the understanding of the ephemeral, the uncertainty and complexity that this dissertation was built. It is the result of my inquiries before the school and the difference(s) among students. I intended to dip in school life (re)visiting teaching practices embodied in the curricula made/invented various forms of questioning to be/seem/to be of the

6. Identification of Mycobacterium tuberculosis complex based on amplification and sequencing of the oxyR pseudogene from stored Ziehl-Neelsen-stained sputum smears in Brazil
A cross-sectional analysis of stored Ziehl-Neelsen (ZN)-stained sputum smear slides (SSS) obtained from two public tuberculosis referral laboratories located in Juiz de Fora, Minas Gerais, was carried out to distinguish Mycobacterium bovis from other members of the Mycobacterium tuberculosis complex (MTC). A two-step approach was used to distinguish M. bovis

7. ESTIMAÇÃO DE FASORES NA PRESENÇA DE HARMÔNICOS, DECAIMENTO CC EXPONENCIAL E INTER-HARMÔNICOS EXPONENCIALMENTE AMORTECIDOS
This thesis presents the proposition of two novel methods in the field of phasor estimation. The first proposes to estimate the phasor of the fundamental component in the presence of harmonics and exponential decaying DC. This methodology is based on the application of filters DFT (Discrete Fourier Transform) and some methods of signal processing such as win

8. SÍNTESE E CARACTERIZAÇÃO DE COMPLEXOS DE PLATINA COM LIGANTES DIAMINADOS N-ALQUILADOS DE CADEIA LONGA CONTENDO UM GRUPO HIDROXILA
Cancer is considered one of the main causes of death around the world. This disease can be treated using radiotherapy, surgery, and chemotherapy. Since the discovery of the anticancer activity of cisplatin, studies involving the use of metal complexes as drugs have grown substantially. Aiming to improve the spectrum of antitumor activity, to decrease side ef

9. ESTUDO TEÓRICO DE ESTRUTURA, PROPRIEDADES E REATIVIDADE DE TRIGLICERÍDEOS E ÉSTERES DE ÁCIDOS GRAXOS ENVOLVIDOS NA PRODUÇÃO E COMPOSIÇÃO DO BIODIESEL
The present work aims the study of structural and thermodynamic properties for process involving triglycerides (TG), fatty acid esters (EAG) and biodiesel through theoretical and chemometrical methodologies. The study of the transesterification reaction of triglycerides (TG) using cyclodextrin (CD) as a potential catalyst were also carried out. Initially, th

10. DESENVOLVIMENTO, OTIMIZAÇÃO E VALIDAÇÃO DE METODOLOGIAS POR ELETROFORESE CAPILAR PARA ANÁLISE DE FÁRMACOS UTILIZADOS NO TRATAMENTO DA TUBERCULOSE
The main focus of this thesis was the development, optimization and validation of analytical methodologies for analysis of pharmaceutical preparations used for tuberculosis treatment, which contain as active ingredients, ethambutol (ETB), isoniazid (ISO), rifampicin (RIF) and pyrazinamide (PYR) isolated or in association. Two analytical methodologies for ETB

11. The Juiz de Fora Complex in the region of Três Rios (RJ): lithogeochemistry, geochronology e isotopic geochemistry of Nd / O complexo Juiz de Fora na região de Três Rios (RJ): litogeoquímica, geocronologia U-Pb (LA-ICPMS) e geoquímica isotópica de Nd
The Juiz de Fora Complex (JFC) in the region of Três Rios (Rio de Janeiro) is appointed by an ample variety composicional, having from granites, tonalite to rocks of composition basic. Through the lithogeochemistry it was possible to subdivide this unity in 4 associations: (i) calc-alkaline of high-K, (ii) calc-alkaline of medium-K, (iii) tholeiitic and (iv

12. SOLVING THE BIDOMAIN EQUATIONS USING GRAPHICS PROCESSING UNITS / Solução das Equações do Bidomínio em Processadores Grácos
The computational modelling of the heart has shown to be a very useful tool in the functional bioinformatics eld. The models, becoming more realistic each day, provide a better understanding of the complex biophysical processes related to the electrical activity in the heart as in the case of cardiac arrhythmias. However, the increasing complexity of the mod
