A discrepância de tamanho dentário, de Bolton, na oclusão normal e nos diferentes tipos de más oclusões, bem como sua relação com a forma de arco e o posicionamento dentário

Esta pesquisa teve como objetivo geral avaliar a discrepância de tamanho dentário, na oclusão normal e nos diferentes tipos de más oclusões e a sua relação com as medidas que determinam a forma de arco e o posicionamento dentário na região anterior. Para tanto, foram estudados 185 pares de modelos de gesso, divididos em 4 grupos: Grupo 1 (composto por 41 pares com Oclusão Normal, sendo 20 do gênero masculino e 21 do gênero feminino); Grupo 2 (composto por 44 pares com má oclusão de Classe I, divisão 1, sendo 22 do gênero masculino e 22 do gênero feminino); Grupo 3 (composto por 54 pares com má oclusão de Classe II, sendo 28 do gênero masculino e 26 do gênero feminino) e Grupo 4 (composto por 46 pares com Classe III, sendo 23 do gênero masculino e 23 do gênero feminino). Observou-se que não ocorreu dimorfismo sexual entre as discrepâncias de tamanho dentário e os diferentes tipos de oclusão dentária; as proporções estabelecidas por Bolton não se aplicaram ao grupo com Oclusão Normal; na Oclusão Normal, Classe I, Classe II e Classe III, houve um predomínio de excesso dentário total (RAZ12) no arco inferior; na Classe I houve uma igualdade na distribuição de excesso dentário anterior (RAZ6) nos arcos superior e inferior; na Oclusão Normal, Classe II e Classe III, ocorreu um predomínio de excesso dentário anterior (RAZ6) no arco inferior, em relação ao arco superior; os excessos dentários não contribuíram na ocorrência das más oclusões e as discrepâncias total e anterior (RAZ12 e RAZ6) não interferiram diretamente nas larguras e comprimentos dos arcos, bem como no posicionamento dos dentes anteriores.

CMS physics technical design report, volume II: Physics performance

CMS is a general purpose experiment, designed to study the physics of pp collisions at 14 TeV at the Large Hadron Collider ( LHC). It currently involves more than 2000 physicists from more than 150 institutes and 37 countries. The LHC will provide extraordinary opportunities for particle physics based on its unprecedented collision energy and luminosity when it begins operation in 2007. The principal aim of this report is to present the strategy of CMS to explore the rich physics programme offered by the LHC. This volume demonstrates the physics capability of the CMS experiment. The prime goals of CMS are to explore physics at the TeV scale and to study the mechanism of electroweak symmetry breaking - through the discovery of the Higgs particle or otherwise. To carry out this task, CMS must be prepared to search for new particles, such as the Higgs boson or supersymmetric partners of the Standard Model particles, from the start- up of the LHC since new physics at the TeV scale may manifest itself with modest data samples of the order of a few fb(-1) or less. The analysis tools that have been developed are applied to study in great detail and with all the methodology of performing an analysis on CMS data specific benchmark processes upon which to gauge the performance of CMS. These processes cover several Higgs boson decay channels, the production and decay of new particles such as Z' and supersymmetric particles, B-s production and processes in heavy ion collisions. The simulation of these benchmark processes includes subtle effects such as possible detector miscalibration and misalignment. Besides these benchmark processes, the physics reach of CMS is studied for a large number of signatures arising in the Standard Model and also in theories beyond the Standard Model for integrated luminosities ranging from 1 fb(-1) to 30 fb(-1). The Standard Model processes include QCD, B-physics, diffraction, detailed studies of the top quark properties, and electroweak physics topics such as the W and Z(0) boson properties. The production and decay of the Higgs particle is studied for many observable decays, and the precision with which the Higgs boson properties can be derived is determined. About ten different supersymmetry benchmark points are analysed using full simulation. The CMS discovery reach is evaluated in the SUSY parameter space covering a large variety of decay signatures. Furthermore, the discovery reach for a plethora of alternative models for new physics is explored, notably extra dimensions, new vector boson high mass states, little Higgs models, technicolour and others. Methods to discriminate between models have been investigated. This report is organized as follows. Chapter 1, the Introduction, describes the context of this document. Chapters 2-6 describe examples of full analyses, with photons, electrons, muons, jets, missing E-T, B-mesons and tau's, and for quarkonia in heavy ion collisions. Chapters 7-15 describe the physics reach for Standard Model processes, Higgs discovery and searches for new physics beyond the Standard Model.

Particularmente neste texto, apresentamos os resultados dos trabalhos desenvolvidos mediante análise dos aspectos da configuração textual dos relatos orais de ex-partícipes do Programa que evidenciaram desafios que, historicamente, permanecem em aberto, dentre eles, os referentes ao desequilíbrio quanto à representatividade dos Programas das universidades estaduais com relação aos das estaduais nos órgãos colegiados centrais e à exigência de super especialização dos Programas quanto às suas propostas de investigação.

Study of stress distribution with finite element method in a root with prefabricated threaded split shaft post - Part I

A finite element analysis was carried out to study the role of prefabricated threaded split shaft post (Flexi-Post) on dentinal stress in pulpless tooth. Three dimensional plane strain model of mesio-distal section of a human maxillary central incisor without restoration was analysed with the MSC/NASTRAN (MacNeal/ Schwendler) general purpose finite analysis program was executed on a microcomputer. The model as discretized into 48.954 axisymmetric finite elements defined by 10.355 nodes. Each element was assigned unique elastic properties to represent the materials modeled. Homogeneity, isotropy and linear elasticity were assume for all material. A simulation of static load of 100N was applied to the incisal edge of the post; vertical. Maximal principal stresses and von Mises equivalent stress were calculated. Using the element analysis model employed in this study, the following can be concluded concerning threaded split shaft post (Flexi-Post): Maximum principal stresses in dentin were located at cervical place and at the post apex. The apical threads of the post not redirecting stresses away from the root.

New approach of induction machine drive using an adaptive digital PID controller with gain planning based on artificial neural networks

The present work introduces a new strategy of induction machines speed adjustment using an adaptive PID (Proportional Integral Derivative) digital controller with gain planning based on the artificial neural networks. This digital controller uses an auxiliary variable to determine the ideal induction machine operating conditions and to establish the closed loop gain of the system. The auxiliary variable value can be estimated from the information stored in a general-purpose artificial neural network based on CMAC (Cerebellar Model Articulation Controller).

Construction and test of low cost X-ray tomography scanner for physical-chemical analysis and nondestructive inspections

X-ray computed tomography (CT) refers to the cross-sectional imaging of an object measuring the transmitted radiation at different directions. In this work, we describe the development of a low cost micro-CT X-ray scanner that is being developed for nondestructive testing. This tomograph operates using a microfocus X-ray source and contains a silicon photodiode as detectors. The performance of the system, by its spatial resolution, has been estimated through its Modulation Transfer Function - MTF and the obtained value at 10% of MTF is 661 μm. It was built as a general purpose nondestructive testing device. © 2009 American Institute of Physics.
