Population growth, together with the gradual social ascent in Brazil, reflects at the growing need for better use of urban spaces. In this context, the amount of new buildings to meet the demand in property market, the needs for creating new roads and highways, among others, make the use of geotechnical works and, more specifically, retaining walls, more and more common. One of the simplest solutions for underground works is the use of retaining structures using tie back walls for soil support, therefore, the present work deals with this kind of structures. This paper proposes the use of FTOOL software testing in predicting deformations in tie back walls, by comparing simulations of the presented model to a real and measured deformation case in Guabirotuba Formation (PR). The results showed the importance of defining the parameters such as stiffness and curtain geometry, as well as the definition of representative loads acting on it. Also, it was pointed out that the passive response of the steel rods depends on the horizontal displacement of the wall. The study concluded that the program generates very representative results when compared to field data and seems to be a promising tool for tie back structures displacement predictions

The need to use waste from wood processing industry grows due to environmental demands imposed by laws, so like the need to introduce more competitive products in the market (it means better quality and acceptable cost) who must submit by the rational use of raw material, usually turning waste to sub products, what adds higher value for that. To this research, specific case from Ribon Company, located on Camaçari, Bahia-Brazil, has been studied. It is a treated wood producer. Bulk of monthly wood logs there is 70 m3. Its yield is 71,43%, where bulk of generated waste is monthly 20m3. As an exploitation way from generated waste, it has been suggested some options like: erosion protection to specific areas, a wildlife shelter as an henhouse etc, recreational articles, coal, linings, treadmills. However this research will give focus to the furniture design made of waste. As a conclusion, there is very much need to assign new utilizations to that sub used materials, since there is significant amount to increase company’s productive yield

The guidelines of National Curriculum for Dental courses highlights the necessity in providing for the professional the ability to analyze and assess community’s problems and needs, and to create solutions for the society. The continuing education may be considered a useful tool for the teaching and learning because it favors the diversification of learning environments, which allows the insertion of undergraduate and graduate students into the real scenarios. This current study aimed to assess the Public Health projects and programs of the UNESP – Araçatuba Dental School, by describing the interaction experiences between faculty and health services in the professional career development. Historical, documentary and descriptive searches were performed based on the faculty archives such as official documents, reports, databases from the Pro-rector of continuing education and published papers in the period between 1964 and 2011. The following experiences were noted: the Extra-Muro Dental Service (SEMO), established in 1964, that focused in providing dental treatment to the rural population, highlighted the social inclusion of discriminated society groups since that time. In 1972, this service was expanded to several specific populations living in the urban areas. In the '60s, many educational campaigns were performed as homemade water filter and construction of wells and septic tanks which demonstrate the concern with the determinants of healthdisease process. At that time, the campaign of fluoridation of public water supplies in several counties started as Araçatuba, Birigui, Penápolis, Guararapes, Valparaíso and so on. The Campaign of “Good Teeth” from the '70s became wider over time and it was transformed in the "Oral Health Education Program" and it was continuously developed in all public schools of Araçatuba and some neighboring towns, benefiting children aged from 6 to 10 years-old. Several epidemiological studies of caries, periodontal diseases, malocclusion and fluorosis were conducted in cooperation with local governments, and counted with the participation of undergraduate and graduate students. Pereira Barreto – SP was the precursor city in Brazil to carry out fluorosis study. Currently, 12 projects of Public Health from the Institution of Higher Education in the Pro-rector of continuing education are being developed. The concern in qualifying the human resources in health is confirmed with the development of training courses and workshops for professionals, highlighting the training for people enrolled in the Family Health program; Community Health Agent training - Solidarity University, and Municipal Health Counselors training. The Graduate Program in Social and Preventive Dentistry, created in 1993, has an important role to train several professionals for the Unified Health System, and provides education to create researchers, professors and administrators, and enucleates research groups in several Brazilian states. In all activities showed herein, a dynamic participation of undergraduate and graduate students has been observed, and several books, guidelines, articles, brochures and booklets have been published as a result of the continuing education activities.. It was concluded that different projects and programs have been developed by the Public Health of UNESP –Araçatuba Dental School, which allow the exchange of experience between the university and health services, and benefit all participants enrolled in these activities.

This study is based on the mapping of occurrences associated with social vulnerability and natural risks, which refer to the resilience of populations and territories, regarding natural hazards associated with the functioning of natural systems (eg, earthquakes, flood, mass movements). According to UNISDR (2014), the state of São Paulo is a reference in working with Urban Resilience and Disaster in the Resilient Cities Campaign (2014), considering the high investment in Risk Areas Mapping and Public Education Campaigns implemented by the Civil Defense. Thus, this study aims to mapping the occurrence of events related to Tree Falls, Erosion, Landslides, Irregular Housing, Rocky Blocks Falls, Wall Falls, Unroofing and Irregular Construction, attended by the Civil Defense in the city of Santos, São Paulo State, from 2011 to 2014. Thereafter, correlated analyzes to the Environmental Vulnerabilities were generated. The Environmental Vulnerability databases used in this dissertation compose the results of the CNPQ Project - Environmental Vulnerability Mapping of the State of Sao Paulo - Brazil: a methodological contribution of Freitas (2013) and Bortolettoet al (2014), with information collected from the 2010 Census (IBGE, 2010), on a census sectors scale. The adopted methodological procedure involves document analysis followed by data integration in Geographic Information System, through algorithms analysis and mapscrossing.The results obtained in Maps of Social and Environmental Vulnerability Occurrences presented areas of High or Very High Vulnerability. The main variables obtained with such characteristics are Irregular Housing, Landslides and Rocky Blocks Falls, which was associated with hilly terrain formations, with slopes above 30%. To the areas of Medium, Low and Very Low Vulnerability were associated the variables Tree Falls, Wall Falls, Erosion, Unroofing and Irregular Construction, which are spatially distributed without an...

The synthesis and structural characterization of a europium complexed fluorene-bipyridine copolymer are described. A level of ion insertion of 80% in molar basis was achieved, and theoretical calculations showed that it required a twist of 179 degrees (49 kJ) between the pyridine units. Spectroscopy data showed that no electronic coupling between the main backbone and the complexation sites had occurred, but these hindered the interchain aggregation observed in the non complexed polymer. Preliminary electroluminescence studies showed that the EL and PL spectra are consistent, and that the ion had a trapping effect in the charge transport. (C) 2011 Elsevier B.V. All rights reserved.

Cochlear implantation is a safe and reliable method for auditory restoration in patients with severe to profound hearing loss. Objective: To describe the surgical complications of cochlear implantation. Materials and Methods: Information from 591 consecutive multichannel cochlear implant surgeries were retrospectively analyzed. All patients were followed-up for at least one year. Forty-one patients were excluded because of missing data, follow-up loss or middle fossa approach. Results: Of 550 cochlear implantation analyzed, 341 were performed in children or adolescents, and 209 in adults. The mean hearing loss time was 6.3 +/- 6.7 years for prelingual loss and 12.1 +/- 11.6 years for postlingual. Mean follow-up was 3.9 +/- 2.8 years. Major complications occurred in 8.9% and minor in 7.8%. Problems during electrode insertion (3.8%) were the most frequent major complication followed by flap dehiscence (1.4%). Temporary facial palsy (2.2%), canal-wall lesion (2.2%) and tympanic membrane lesion (1.8%) were the more frequent minor complications. No death occurred. Conclusion: There was a low rate of surgical complications, most of them been successfully managed. These results confirm that cochlear implant is a safe surgery and most surgical complications can be managed with conservative measures or minimal intervention.

Background: Initially described by Gorlin et al. in 1962, the calcifying cystic odontogenic tumor (CCOT) may be associated with unerupted teeth, ameloblastomas, adenomatoid odontogenic tumors, and, in many cases, with odontomas. It is rare in patients in the first decade of life, particularly involving deciduous teeth. Surgery is the treatment of choice, with low recurrence rates. Case report: We present a clinical case of CCOT associated with odontoma and a missing deciduous tooth in a 3-year-old female patient. The lesion was removed under general anesthesia. The patient has been followed up for 1 year, and no recurrence was found. This appears to be the first report in such a young age

Background: Central giant cell granuloma is a benign condition of the jaws which may present an aggressive behavior. Case report: A 9-year-old boy was complaining of swelling in the floor of the mouth. A solid swelling was observed in the area of the lower incisors. From the radiographic exam, we observed a radiolucent image in the mandibular bone with well-defined limits extending from the apical region of tooth 33 to the apical region of tooth 42. Discussion: Due to the diagnosis and the age of the patient, we chose a conservative treatment, administering subcutaneous injections of calcitonin. During this treatment, no reduction to the lesion was observed. Therefore, we chose to treat the lesion with triamcinolone acetonide. Monthly follow-ups demonstrated good lesion reduction and the absence of any clinical symptoms during the first 2 years. After a 3-year follow-up, the patient returned, presenting mobility of the lower incisors. A significant increase in the size of the lesion was observed. After a biopsy, with the removal of tissuewhich had the appearance of a cyst capsule, microscopic analyses were found to be compatible with a secondarily infected cyst. Two months following this procedure, the patient did not present tooth mobility anymore and the oral mucosa presented a normal aspect. Following a radiographic exam, full lesion repair was observed. These conservative treatments should be the first option in cases of central giant cell granuloma and the patient must be observed for a long period of time, until no further clinical or radiographic signs of lesions are observed

Dilthey apontou primeiro a psicologia e depois a hermenêutica como tendo papel fundamental para sua filosofia da vida, cujo principal objetivo prático é desenvolver a pedagogia ou teoria geral da educação. A pedagogia necessita da ajuda da ética para estabelecer seus fins e da psicologia para indicar seus meios. Este texto tem por objetivo mostrar a relação entre hermenêutica da vida e pedagogia, para Dilthey. A filosofia da vida do autor, ao adotar procedimento hermenêutico, exercita a compreensão ou busca de significado das criações humanas histórico-sociais por um tipo especial de relação entre as partes e o todo. É justamente dentro desse balanço hermenêutico que propomos apagar qualquer vestígio de ruptura, brecha ou contradição entre a busca de princípios universais da ação humana e a impossibilidade de construção da tarefa humana moral, por meio de princípios universais. Só em 1890 Dilthey deu início às conhecidas conferências sobre ética, na Universidade de Berlim. Tais conferências, publicadas em 1958 por Herman Nohl, no volume X das Obras Completas, apontam as diretrizes do caminho que deverá consolidar a ética formativa ou social, enquanto solução histórica para o alcance de princípios universais de orientação para a conduta humana. Essa trajetória efetiva-se graças ao exercício distintivamente humano da autorreflexão. Por meio dela, é possível cumprir nosso destino de manifestar, exteriorizar no tempo a energia do espírito absoluto que nos é imanente. Diante desse panorama, este texto procura sublinhar como é possível que tal pedagogia possa respeitar sua tarefa universal de orientar historicamente o desenvolvimento das novas gerações, sem dirigir o processo por meio de fins rígida e fixamente estabelecidos.

Abstract This paper describes a design methodology for piezoelectric energy harvester s that thinly encapsulate the mechanical devices and expl oit resonances from higher- order vibrational modes. The direction of polarization determines the sign of the pi ezoelectric tensor to avoid cancellations of electric fields from opposite polarizations in the same circuit. The resultant modified equations of state are solved by finite element method (FEM). Com- bining this method with the solid isotropic material with penalization (SIMP) method for piezoelectric material, we have developed an optimization methodology that optimizes the piezoelectric material layout and polarization direc- tion. Updating the density function of the SIMP method is performed based on sensitivity analysis, the sequen- tial linear programming on the early stage of the opti- mization, and the phase field method on the latter stage
