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

Objectives: The objective of this study was to evaluate the ability of endodontists and general practioners to perform the differential radiographic diagnosis between internal and external root resorptions, using digitized periapical radiographs. Methods: Thirty periapical radiographic images of external and internal resorption were selected. The evaluators were comprised of 15 endodontists and 29 general practitioners who answered a questionnaire with the following question: “What type of resorption in the following radiographics do you diagnose?” (1) Inflammatory external root resorption. (2) Internal root resorption. Statistical analysis was performed based on the Mann-Whitney test, with significance level of 5%. Results: There was no statistically significant difference in the percentage of correct answers from specialists in endodontics and general practitioners. Conclusions: Both groups demonstrated satisfactory skill in the radiographic interpretation of internal and external resorption and there was a higher percentage of correct diagnosis of internal resorption than the external.

A perda embrionária consiste em perda econômica significativa dentro do processo de criação de equinos e representa custos adicionais para os criadores decorrentes das repetidas coberturas de éguas durante a temporada reprodutiva, além da diminuição do número de potros nascidos. São consideradas perdas embrionárias aquelas que ocorrem até o 49º dia da gestação e são decorrente de diversos fatores maternos e/ou embrionários. Atualmente, com a utilização da ultrassonografia, pode-se observar a vesícula embrionária a partir do 11º dia pós-ovulação, sendo possível o diagnóstico precoce de tais perdas. Devido ao grande prejuízo econômico na reprodução equina decorrente de perdas gestacionais, o objetivo deste Trabalho de Conclusão de Curso foi realizar revisão de literatura sobre as principais causas da perda embrionária em éguas

This research analyses the positives and/or negatives of external reviews to work's organization developed at the/and by the school. It should be noted that it's a qualitative case of empirical research, and it takes the pattern of case's study, because we held the investigation just in one school, which in turn, belongs to the education's public network by the state, and is located at the São Paulo northwest. The tools employed at this research for the data's collect were the observation, restricted to times of Pedagogical Work Activities Collective from the school, and the semi structured interviews with educational coordinators and the teachers too. We choose educational coordinators and teachers because they are closer with the education and learning methods, as well as their activities have more responsibility in relation to the main function developed by school, that is to teach, in other words, educational processes. This research also concerns an investigation about the educational coordinators and teachers conceptions, in relation to system's implantation external reviews at the schools. The results indicate to incidence of significant interference of the external reviews to/in the organization school's work, as, a teaching practice reorientation from results arising these reviews, or, modifications in the internal rating, since they have followed a tendency towards becoming more similar with their own external reviews. In what concerns the subjects investigated, we can emphasize that mostly submitted alienation with respect to negative effects of the external reviews for school. They showed that are conformed with the reality that they are inserted and in your mostly they proved perceive the positive effects by the implantation of external reviews. We can also add that the data obtained in the research allow us declare that the work of the educational coordinators of this school in presence of external reviews don't...

In recent years, public schools have experienced the deployment of external evaluation that, legally, should promote the development and deployment aimed at enhancing the educational process of teaching offered at the country's public policy systems. However, such a situation occurred in a broader regulations of teaching and managerial measures and performative nature context generated implications in everyday school life, notably due to the pressure exerted on schools before the publicity of accountability for results and performance indicators changing, in many cases, the purpose of teaching work. In this context we understand that it is very important to discuss the history and characterization of implanted a city in São Paulo state systems, and vision teachers about them, and the consequences that assessments have caused in practice in the classroom. So be performed an empirical research of qualitative nature in four elementary schools-cycle Teaching I and II, with the aim of analyzing the perception of teachers about external reviews of a municipal school. As an instrument for data collection dense interview with teachers that will be used will be audio-recorded and then transcribed and analyzed with the support of the theoretical frameworks adopted

Halitosis is the unpleasant odor of exhaust air through the mouth and lungs. There are over 50 causes, and approximately 90% of cases, is of oral origin. May have physiological origin (stress, breath of morning, fasting, and inappropriate diets), local reasons (bad oral hygiene, bacterial plaque retained on the tongue and/or tonsils, lower production of saliva, gum disease) or systemic reasons (diabetes, kidney or liver problems, constipation, etc.). In the Third Age, this problem tends to increase significantly. Thus, the aim of this study was to detect the presence of halitosis in the geriatric group attended in the dental clinic of UNIRP, identifying their incidence and principal causes. The sample consisted of 48 volunteer patients aged 60 years or older and included more than 90% of patients treated in this age group. It was performed a anamnesis and physical examination. The intra-oral halitosis was detected using a breath meter (halimeter). In the group studied, approximately 54.16% had halitosis, 84.61% of these were users of the prosthesis. The tongue coating was present in 80.76% of individuals with halitosis. After brushing the tongue, 88.46% of patients with halitosis have had the initial index oral malodor decreased. Based on the results of this study it was concluded that factors as dental prostheses and tongue coating are critical factors in causing halitosis.

The swine culture potentially generates waste with high organic load and pollutants, being responsible for the spread of pathogens, contamination of rivers, groundwater and soils, besides it produces foul odors and emit greenhouse gases. However, the high amount of organic matter, which expresses the amount of pollutant load, reflects the energetic potential of these wastes used as raw material in biogas generation through technology of digesters. The properly use of theses digesters provides the production of clean energy and promotes the conservation of the environment. The economic viability of the implantation of an Indian model digester on a small swine farm was verified based on the value from initial investments of deployment, maintenance costs, depreciation, and on the interest and revenues arising from the system. Besides, the amount of biogas produced daily and the average consumption of biogas by the most common used devices such as refrigerator, stove, water heater, and generator of electricity was calculated.. For a backdrop of 10 years, the results of economic indicators NPV of BRL 57,598.95, IRR of 48.38%, Simple Payback of 2.06 years, and Discounted Payback of 2.3 years, demonstrated a favorable outlook for the use of this technology, with the possibility to generate economic, social and environmental benefits.
