Análise de causas de trincas em carro de translação de empilhadeira/recuperadora

The present work aims to study the possible causes of cracks founded and recovered in translation cars of ore Forklift / ore Reclaimer. To identify the possible causes of cracks observed on the equipment it was used a static approach analysis, using a finite element method as an analysis tool, using a specific structural analysis program. After making the model, a strain gage measurement was necessary because there may be significant amounts of masses of non-structural components that were not modeled and were not available in the drawings, as well as fouling ore. With the calibrated model it was processed analyses with the load cases of dead load, product, wind and excavation. After the processing, it was observed that none of these load cases resulted in values that caused the crack, so another three hypotheses were tested: depression and misalignment, jacking and translation of only three cars. Of these three hypotheses it was observed that the jacking coud be the cause of the cracks, because the distribution of stress. Due to the miss of parameters, like the height utilized in this process, it was not possible to affirm the real stress level

Caracterização do fator de intensidade de tensão em corpos trincados através do método dos elementos finitos

The industry generally has sought materials with high mechanical resistance, low density, thermal stability and corrosion resistance. In the aerospace industry, for example, the use of aluminum alloys, such as Al 2024-T351 and Al 7075-T7351, have become essential. However, the use of these materials often do not resulted in a satisfactory performance of the component, since the presence of cracks can cause total rupture of the component, even with a tension below the yield stress of the material, unexpectedly. In this work, these aluminum alloys were analyzed and samples were modeled by the finite element method. Moreover, in the models were applied two different types of cracks, central and edge crack, a vertical force was applied to result in a tension 70% of the yield stress of the material analyzed. Through stress asymptotic distribution in the region near the crack tip were calculated the values of the stress intensity factors for each crack length, after the stress intensity factors characterized were compared graphically with the values of fracture toughness found in the available literature

Cronopoiese e cronotrofia na história em quadrinhos

This article proposes a reflection on the “continuities of the process” in narratives, defined by the closure of the space and by the waiting in time (chronopoiesis), as well as on the “halts of the process” in narratives, defined by the opening of the space and by the repose in time (chronotrophy). In Claude Zilberberg?s proposal about the missive making (le faire missif ), it means, the profound making that governs the becoming of the narratives, temporality and spatiality are related to the categories of closure and opening. The terms chronopoiesis and chronotrophy, established by Zilberberg from the Greek stems, have etymologically in common the stem “krónos”, the time. The first term is added to “poiesis”, “creation”; the second comes together with “trophê”, the “feeding”, the “development”. The remissive making, that carries the “continuities of the process”, is chronopoietic (the expectant temporality, which creates the waiting time), and spatially closed. On the other hand, the emissive making, which carries the “halts of the process”, is chronotrophic (the “originating” temporality, because it is “fed”, creating the passing time) and spatially open. Our reflection on chronopoiesis and chronotrophy aims at verifying if these temporal operations of the missivity necessarily correspond to spatial closures and openings, respectively, as the Zilberberg’s model proposes, in verbo-visual narratives, specifically in comics.

A instalação do serviço de inspeção escolar na Província de São Paulo (1835-1887)

This article discusses the establishment of the school inspection service in the Province of Sao Paulo between the implementation of the Provincial Legislature in 1835 and the last years of the monarchy. In this work, were taken as sources - the Collection of Laws and Decrees of the Province of São Paulo (1835-1889); Speeches of the Presidents of the Province given annually at the opening of the Assembly of S„o Paulo (1835-1889), and the reports of the General Inspectors presented to the President of the Province (1851-1889). To give theoretical support to this analysis, we used the categories of Weberian bureaucratic organization.

Alterações dimensionais em pacientes submetidos à expansão rápida da maxila com aparelho do tipo Haas

The maxillary atresia is a alteration in the transverse dimension that can result in a unilateral or bilateral crossbite. For correction of atresia of the upper dental arch appliances with the intent to expand the arch of orthopedic or orthodontic manner are used, obtaining across-compatibility between the dental arches. The purpose of this study was to evaluate the dimensional changes of the maxillary in patients in the mixed dentition with atresia in the upper dental arch, using occlusal radiographs taken before, after rapid maxillary expansion and after removal of the appliance. Methods: the sample consisted of 35 patients who used the appliance type conventional Haas, in the mixed dentition, according to the standard protocol for installation, activation, containment and removal of the appliances rapid maxillary expansion. Results: the results confirm that the suture opening occurs in greater quantities in the anterior (4.3 mm) than posterior to (3.74 mm), representing a triangular opening of 7 degrees on average with the posterior opening 87% of the quantity of anterior opening. The molars region expanded about 5 mm, and the base bone 3.7 mm, representing a 74% bone expansion of the expansion teeth.

Efeitos esqueléticos e dentários decorrentes da expansão rápida maxilar

This study evaluated the maxillary transversal changes caused by the rapid maxillary expansion (RME) accomplished by Hyrax appliance. Sixteen children from both genders were selected and treated, with ages between 7.7 to 10.8 years, who presented unilateral or bilateral posterior crossbite. Postero-anterior radiographs were taken at the beginning of the treatment, end and post-retention period. The treatment promoted an average opening of 8.8 mm of IMD (intermolar distance), 2.33 mm of IAD (interapex distance) and none of IID (interincisal distance). At the end of retention period, relapse was observed, with a decrease of 4.3 mm of IMD, 1.23 mm of IAD, a non-significant enlargement of IID (0,38 mm).These results confirm the significant influence of Hyrax appliance on transverse dimensions, represented by enlargement of IMD and IAD and its effectiveness to solve posterior crossbites.

Análise dos troncos radiculares, abertura da raízes e projeções cervicais de esmalte de furcas de molares superiores e inferiores: Estudo in vitro

Periodontal treatment of teeth with furcation lesions often have unpredictable results due to several factors that may hinder therapy or influence the progress of periodontal disease. Of these, the length of the root trunk may contribute to the early injury of the furcations or even cause complications for the application of the treatment; the opening of the roots can guide the type of treatment to be instituted and cervical enamel projections may hinder the instrumentation of the region or even act as a retention plate niche. Thus, the purpose of this study was measured using a digital caliper, root logs database 400 molar both the 1st and the 2nd and both upper and lower as well as analyze using appropriate index type projection cervical enamel and through appropriate classification the opening of the roots in order to guide the diagnosis and treatment plan. We conclude that there is variation in measures of root trunk between the faces of the teeth examined and that greater cervical enamel projection (ECP) correlates with a decrease in the length of the root trunk in the sample evaluated as the first molars have higher occurrence of roots with a degree of opening larger than the second molars.
