The present work deals with the study on the evaluation of the human health risks caused by the leaching of hydrocarbon products from a gas station in Sumaré-SP. First, a geoenvironmental diagnosis had to be done, where information such as: history of the area, chemicals involved, geological characteristics, transport, chemical analysis, were used to make it. The geoenvironmental diagnosis was used in the software RBCA tier 2 which established the risks by all possible pathways. The results indicated that there are risks for groundwater ingestion for commercial (on site and off site) and residential receptors and 10 that there´s risk for inhalation of vapors in enclosed space for the commercial receptor on site. The evaluation also calculated the specific target levels that the area needs to show, in order not to harm human beings and the environment. That makes RBCA a great tool that can helps the remediation actions needed to be done so that the human being and the environment remain secure.

The objective of this paper is to discuss the construction of the image of São Paulo state public schools teachers in the public sphere, by the media and the trade union press, and see how that image is formed in both of them, without making any comparisons, from the covering of 2010 strikes by newspapers Folha de S. Paulo and Jornal da Apeoesp. This paper uses as theoretical basis the study of Media Hegemony, the concept of Radical Media and Public Sphere, as well as the relationship between them and social movements. It also considers the observation of the history and characteristics of trade union press and the Standards of Manipulation by the Press, proposed by Perseu Abramo. The chosen method was the identification, selection and organization of stories about education published by Folha de S. Paulo during the period; the application of Abramo’s proposed manipulation standards on the stories about the strike; research, selection and observation of print publications (Jornal da Apeoesp and newsletters Apeoesp Urgente) about the strike, published by Apeoesp during the same period

O Projeto de pesquisa Mensagem, imagem e ideologias centrou seu foco principal na análise de figuras e signos ideológicos contidos nas placas e nos outdoors da cidade de Rio Claro-SP e região, no âmbito de divulgação de Instituições de Ensino. Pesquisamos os eixos transversais sobre a visão de educação e infância, a ponte entre os signos e o visual, as idéias contidas no processo das propagandas e o que se pretende vender com as imagens e os códigos expostos. Determinamos tais meios de comunicação, com propagandas de escolas de quase todos os níveis de escolaridade, para demonstrar e ilustrar as idéias contidas na aliança entre o capitalismo e a mídia, principalmente a fim de explicitar os fundamentos políticos, suas concepções e possíveis implicações na administração do processo educacional.

This paper deals with a case study of assessing risk to human health, with the study area of an industrial site in the city of Paulinia (SP) contaminated by oil, which is disturbing situation that occurs in the state of Sao Paulo, which represents risks for human health, as toxic and carcinogenic potential of petroleum products. As an essential foundation for risk assessment, a Geo-environmental diagnosis of the region was made, posing as historical information of the area and accidents, regional geology and hydrogeology, characterization of contaminants and affected media, contaminant transport and data on potential receptors and pathways. Because of the detection of contaminants above the intervention values CETESB (2005) it was possible to proceeded to quantify risks to human health and the determination of maximum acceptable concentrations for no damage to health, using the methodology and software RBCA Tier 2 (ASTM , 1998) and Spreadsheet Risk Assessment recently published by CETESB. The results showed the risk to the health of industrial workers and regular employees of civil works (both on site) for ingestion of groundwater and inhalation of vapors indoors.

The correct distinguishment of microorganisms involved in the periodontal disease pathogen, it is important in the understanding of its progression and adequate treatment planning. Considering this fact, some molecular methods of identification and quantification were developed and are extremely sensitive and precise in the characterization of different bacteria species. The present study aimed to realize a literature review, including studies that realized a comparative analysis between bacterial culture and real time PCR methods in the identification of pathogens. The bacterial culture method can possibly identify new microorganisms and realize antibiotics sensitivity tests. The real time PCR is a microbiologic test that identifies and quantifies bacterial species, through gene amplification of predetermined DNA fragments, with high sensitivity and specificity, and need a shorter operation time of the operator when compared to the bacterial culture method. In this way, to determine a specific diagnostic test, should be considered not only its precision in the identification of microorganisms, but the cost-benefit relationship as well.

The ability to tridimensionally evaluate pathological and anatomical areas, in apical surgery planning, presents a number of advantages. Cone beam computed tomography (CBCT) was developed for dental applications. This paper aims to present a literature review on CBCT, highlighting its advantages over both conventional computed tomography (CT) and radiography. Moreover, its clinical applications in apical surgery are discussed. LITERATURE REVIEW AND CONCLUSION: Unlikely CT, CBCT captures a volume of data in a single 360º rotation, providing benefits such as higher accuracy, better resolution, reduced scanning time and reduced radiation dose. In the maxillofacial region, CBCT has been mainly used in the assessment of dento-alveolar pathology and oral traumatology. CBCT provides a better diagnosis and quantitative information on periodontal bone levels than conventional radiography. It has also been used for patients requiring surgical facial reconstruction, orthognathic surgery, dental implants, and more complex tooth extractions. Besides that, it seems to be a significant tool in modern endodontic practice, presenting useful applications in apical surgery.

Entre as diversas anomalias dentárias, a giroversão dental constitui uma anomalia de grande prevalência, na qual o dente realiza rotação em torno do seu próprio eixo. No exame radiográfico panorâmico é possível verificar a presença de giroversão, porém, quando a dinâmica de giro do eixo do equipamento não coincide com a curvatura da maxila e mandíbula, a imagem dos dentes apresenta-se girovertida ou com apinhamento dental. O presente trabalho teve por objetivo avaliar se as giroversões dentais presentes nas radiografias panorâmicas são verdadeiras ou apenas “virtuais”. Foram selecionadas 71 radiografias panorâmicas com imagens sugestivas de dentes girovertidos, de pacientes que também possuíam a documentação da cavidade bucal por fotografia e modelo de estudo. A média de idade dos pacientes avaliados foi 15 anos de idade. A imagem radiográfica panorâmica, fotografia e modelo de estudo foram avaliadas por um único examinador. Na avaliação das radiografias panorâmicas foram encontradas 246 dentes girovertidos. Porém, ao avaliar a fotografia e o modelo de estudo destes pacientes comprovou-se apenas 127 dentes com giroversão. Estes resultados indicam uma correspondência clinica/radiográfica de 51,4 %, ou seja, 48,6% das giroversões identificadas radiograficamente, eram “virtuais”. Pode-se concluir que o diagnóstico de giroversão dental utilizando a radiografia panorâmica deve ser confirmado pelo exame clínico para evitar diagnósticos falsos positivos.

This text reflects on the techniques and the process of image production and its artistic composition to digital television in high defini- tion, whereas the 4:3 and 16:9 formats will exist until shutdown of the analog signal. Within this period, consumers of television programming that have analog receivers will continue to see the images in 4:3 format. That fact determines that the productions in high definition, while capturing images with larger viewing area and have high contrast ratio (>1000:1) must be main- tain the elements of visual storytelling within the smallest area and with the contrast ratio of the analog tv (30:1), at the risk of distorting visually the messages produced by the directors.
