CARACTERIZAÇÃO GEOLÓGICA, PETROGRÁFICA E GEOQUÍMICA DO MACIÇO SARARÉ NA PARTE SUDOESTE DO CRÁTON AMAZÔNICO

O Maciço Sararé ocorre no sudoeste de Mato Grosso, intrusivo no Domínio Jauru, e encontra-se controlado por trend tectônico NW-SE ligado a tectônica regional transcorrente e, tardiamente, por feições tectônicas rúpteis NE-SW. É constituído por três fácies petrográficas principais denominadas biotita-monzogranito, muscovita-monzogranito e monzogranito, que apresentam contatos transicionais. São rochas leucocráticas, de cor vermelha a rosada, isotrópicas e eqüi/ineqüigranulares a localmente porfiríticas. Os dados geoquímicos as classificam como rochas do tipo S, peraluminosas, alto K, quimicamente restritas e evoluídas em relação a SiO2 alcançando teores em torno de 75%. Os valores de REE apresentam-se dispostos em três curvas assimétricas, evidenciando fácies distintas e mostrando uma redução destes valores e das anomalias de Eu para a fase final. O maciço representa intrusões diferenciadas, geradas a partir da fusão de material da crosta superior em ambiente de colisão continental no final do evento Aguapeí-Sunsás.

O oscilador harmônico singular revisitado

The one-dimensional Schrödinger equation with the singular harmonic oscillator is investigated. The Hermiticity of the operators related to observable physical quantities is used as a criterion to show that the attractive or repulsive singular oscillator exhibits an infinite number of acceptable solutions provided the parameter responsible for the singularity is greater than a certain critical value, in disagreement with the literature. The problem for the whole line exhibits a two-fold degeneracy in the case of the singular oscillator, and the intrusion of additional solutions in the case of a nonsingular oscillator. Additionally, it is shown that the solution of the singular oscillator can not be obtained from the nonsingular oscillator via perturbation theory.

Perfil da fluência: análise comparativa entre gagueira desenvolvimental persistente familial e isolada

PURPOSE: to evaluate and compare the fluency between the familial and the sporadic persistent developmental stuttering, characterizing the typology and the frequency of the disfluencies, the speech rate and the severity of the stuttering. METHOD: 40 participants aged from 6 to 42 years old, divided in two groups with twenty participants in each one: Familial Persistent Developmental Stuttering and Sporadic Persistent Developmental Stuttering. The procedures used were: clinical and familial history, assessment of fluency and Stuttering Severity Instrument. RESULTS: there were no statistically significant differences between the groups regarding the frequency of stuttering like disfluencies, the flow of syllables and words per minute and the severity of stuttering. It was noted a tendency of the group with familial stuttering to show a bigger variability of the severity of stuttering, going from mild to very severe, whereas in the group with sporadic stuttering, the severity varied from mild to severe. CONCLUSION: this study represents the first effort to the characterization of the speech fluency profile of the subgroups of people who stutter, namely familial persistent developmental stuttering and sporadic persistent developmental stuttering. It is possible to conclude that the speech fluency profile of people who stutter, independently of the familial history, is similar. It is noteworthy that the occurrence of some stuttering-like disfluencies, monosyllabic word repetition, block and intrusion were different between groups.

Abordagens da biomecânica ortodôntica utilizando mini-implantes

As an innovative transitory anchorage device, the mini-implants deserve to be described with details regarding its use and action during orthodontic treatment. Therefore, this paper intents to present some biomechanic criteria adopted to for a better use of mini-implants as anchorage in anterior retraction (space closure), molar distalization, mesial movement of the molars, intrusion of molars and as support to provisional implant.

Impact of Replacing Conventional Complete Dentures with Implant-Supported Fixed Complete Dentures

The aim of this study was to assess the impact of replacing conventional mandibular complete dentures with implant-supported fixed complete dentures (ISFDs) on the oral health related quality of life (OHOOL) of edentulous patients and on the associated kinesiographic parameters. The patients had their complete dentures replaced by ISFDs and were assessed after 1, 2, 3, 6, and 12 months. An improvement of general OHQOL was observed 2 months after treatment with ISFDs. Kinesiographic recordings revealed significant mandibular vertical and horizontal opening increases and a greater vertical intrusion of the maxillary complete dentures during clenching after the treatment with ISFD.

Estudo de rochas alcalinas intrusivas na região de Três Fontes - MG

Geological researches conducted in the past few years detected, through deep drill hole data, the presence of alkaline rocks in the region of Três Fontes-MG, where the Barbacena Group rocks, the Morro do Ferro Greenstone Belt rocks and Araxá/Canastra groups‟ rocks are exposed. This paper aimed the petrographic and chemical characterization of these alkaline rock types, which have not yet been described in the literature. Based on petrographic descriptions and geochemical and Scanning Electron Microscopy analysis, it was possible to characterize the rock in question as lamprophyre, rich in carbonates, phlogopite, pyroxene, olivine, titaniferous opaque minerals and apatite concentrations that reach 7%. This occurrence corresponds to an alkaline intrusion, which caused brecciation of host rocks, possibly indicating that the material is explosive, however, in the study area there was no evidence of volcanic activity on the surface

Caracterização petrográfica e geoquímica das rochas encaixantes da mineralização de ouro do alvo lavra velha - Ibitiara (BA)

The Lavra Velha gold prospect is located in Ibitiara city, in the Espinhaço Setentrional physiographic domain, on the west edge of Chapada Diamantina – central part of Bahia. It is inserting on Gavião Block, a compartment of São Francisco Cráton (Almeida, 1977). The Lavra Velha gold dump is formed by an association of hydrothermal breccia lodged in acid and intermediate rocks, classifying in tonalite, granodiorite and diorite, with high alteration, cut off by a vein and venules system constituted by hydrothermal association composed by hematite, tourmaline, quarz and sericite, located in the north limit of Ibitiara granite. In the regional geological context the area is represented by Archaean rocks (Paramirim Complex) and Paleoproterozoic rocks (Ibitiara granitoid and Matinos Granite) constituted the basement, following by paleo to mesozoic pluton-vulcanic-sedimentary association of Rio dos Remédios Group, intruded by mafic rocks. It was used geochemistry and petrographic analysis compiling to field works data to characterize the rocks where the gold mineralization is inserting. Previously these rocks were classifying in volcanic rocks of Novo Horizonte Formation. Developing this monograph’s work the petrogenetic characteristics suggesting that these rocks called volcanic actually belong to Ibitiara granitoid as a portion more metamorphosed. The green schist is the predominant metamorphism in the area with low deformation, associated to high concentration of fluid circulating. The hydrothermal alteration is the process responsible for rocks modifications and strong sericitization generalize
