1. Evaluation of the effect of topical and systemic ozone application in periodontitis: an experimental study in rats
Abstract Objective: The goal of the present study was to determine the effect of systemic and topical ozone application on alveolar bone loss (ABL) by evaluating the effect of Hypoxia-inducible factor −1 alpha (HIF-1-α) and receptor activator of NF-kB ligand (RANKL)-positive cells on histopathological and immunohistochemical changes in a rat periodontiti

2. ASPECTOS TÉCNICOS E OPERACIONAIS DO USO DE MICROTURBINAS CONECTADAS AOS SISTMAS ELÉTRICOS PARA GERAÇÃO DISTRIBUÍDA DE ENERGIA / TECHNICAL AND OPERATIONAL ASPECTS OF THE USE OF MICROTURBINES CONNECT TO THE ELECTRICAL SYSTEM FOR DISTRIBUTED ENERGY GENERATION
The considerable increase in energy demand has increased the interest in reducing costs, improving reliability, quality and stability of power generation systems. The connection of distributed generation (DG) can be used as a strategic element to improve the voltage levels in power system. Microturbines (MT) have certain advantages over other models of GD, s

3. Projeto e construção de um eletropermeabilizador de células biológicas / Design and construction of a biological cell electroporator
Electropermeabilization is the process of transient increase in the permeability of biological membranes of cells subjected to intense electric fields. This technique is currently still in development and has important clinical and technological applications such as electrochemotherapy and gene transfer. Electroporator is the equipment used in the generation

4. Technology mapping for virtual libraries based on cells with minimal transistor stacks / Mapeamento tecnológico para bibliotecas virtuais baseado em células com cadeias mínimas de transistores em série
Atualmente, as tecnologias disponíveis para a fabricação de dispositivos eletrônicos permitem um alto grau de integração de semicondutores. Entretanto, esta integração torna o projeto, a verificação e o teste de circuitos integrados mais difíceis. Normalmente, o projeto de circuitos integrados é consideravelmente afetado com a diminuição do tam

5. Modelagem e previsão de comportamento de processos de injeção de vapor em escalas de laboratorio / Modeling and prediction behavior of steam injection process on laboratory scales
Steam injection is one of the most widely used techniques in the word for heavy oil recovery. The scope of this work refers to the proposition of an experimental apparatus for studying this technique. The apparatus is detailed, with emphasis on its major components, such as: steam generator, steam quality control and the injection prototypes: a tube to study

6. Automatic generation and evaluation of transistor networks in different logic styles / Geração automática e avaliação de redes de transistores em diferentes estilos lógicos
Currently, VLSI design has established a dominant role in the electronics industry. Automated tools have enabled designers to manipulate more transistors on a design project and shorten the design cycle. In particular, logic synthesis tools have contributed significantly to reduce the design cycle time. In full-custom designs, manual generation of transistor

7. Análise de células CD4+CD25+FoxP3+ no timo de camundongos infectados pelo Trypanosoma cruzi. / Analysis of cells CD4 CD25 FoxP3 in the thymus of mice infected for the Trypanosoma cruzi.
Natural regulatory T cells arise in the thymus during the normal process of differentiation and participate in the control of auto and alloimmune responses. Specifically in parasite infections, these cells may have antagonist roles, in favor of the microorganism or the host. Previous studies from our Laboratory revealed that acute Trypanosoma cruzi (T. cruzi

8. Detecção condutométrica sem contato: uma nova ferramenta para monitoramento de interações biomoleculares em microssistemas analíticos / Contactless conductivity detection: a new tool for monitoring biomolecular interactions on analytical microsystems
The study reported in this thesis shows the application of a capacitively coupled contactless conductivity detection (C4D) for monitoring biomolecular interactions on analytical microsystems. Initially, the analytical performance of the microsystems fabricated in glass, poly(dimethylsiloxane) (PDMS) and polyester-toner (PT) was investigated in order to choos

9. Exploração de reordenamento de ROBDDs no mapeamento tecnológico de circuitos integrados / Exploration of ROBDD reordering on technology mapping for integrated circuits
The ROBDDs are structures that have been successfully used in CAD tools for microelectronics. These structures allow canonical representation of boolean functions when established a fixed variable ordering. In the context of an automatic logic cell generator for integrated circuits, ROBDDs may serve as a base for deriving transistor networks from which elect

10. Neuropeptide Y: A hypothalamic brake restraining the onset of puberty in primates
The adult reproductive axis is driven by an intermittent discharge of gonadotropin-releasing hormone (GnRH) generated by a network of hypothalamic neurons known as the GnRH pulse generator. Although this signal generator is operational in infant primates, puberty in these species is delayed by activation shortly after birth of a central neural mechanism that

11. Spatiotemporal control of gene expression with pulse-generating networks
One of the important challenges in the emerging field of synthetic biology is designing artificial networks that achieve coordinated behavior in cell communities. Here we present a synthetic multicellular bacterial system where receiver cells exhibit transient gene expression in response to a long-lasting signal from neighboring sender cells. The engineered

12. Protein synthesis in bacteriophage ghost-infected cells.
Escherichia coli B infected with T4 phage ghosts at 10 mM Mg2+ regains its protein synthesizing activity upon addition of ATP, GTP, and their generator to approximately 2% of the intact exponentially growing cells. In contrast to amino acid incorporation by intact cells, this system is sensitive to EDTA or low Mg2+. On the other hand, this system, differing
