A gênese e a distribuição socioespacial das chuvas no município de Ubatuba-SP

This monograph aims to contribute to the understanding and analysis of extreme events and its correlation with anthropogenic actions, in order to understand the levels of human interference in the environment and to identify potential social and environmental damage that such events may result in Ubatuba, located on the northern coast of São Paulo state. Therefore, two strategies were established, on one hand, episodic analysis of extreme weather events, and on the other, the analysis of the impact of atmospheric phenomena in everyday society. In this case we gave greater emphasis to analysis years that had higher total rainfall. In this sense, the research was based on the standard deviation technique and percentages, which supported to characterize the exceptional rainy years, in addition, use of rhythm analysis technique that has helped to identify the active atmospheric systems. From a qualitative point of view, field works were carried out in order to make use of news by the local press and civil defense for years considered extreme (positive standard deviation). From this, it was analyzed how the extreme episodes of rainfall trigger repercussions in geographic space. Also the spatial distribution of rainfall were carried out by means of quantitative analysis of six rain gauges. It was found that the highest occurrences of impacts, are located in the central areas of the city, as well as the highest rainfall totals. In fact, Ubatuba/SP suffers from very high rainfall totals and has a singularity on the climate...

Estudo das alterações das propriedades mecânicas em aço A-516 grau 70 soldado e submetido a tratamento térmico de alívio de tensões

Pressure vessels are equipments that require a great care because of their high cost and human life risk in case of fail, and its fabrication methods are different for each manufacturer. Normally, pressure vessels and its parts are fabricated by welding, which may change local properties of metals. The head of a pressure vessel is a very important structural component and it is fabricated by welding and mechanical conformation. Because its excellent mechanical properties, de steel A-516 Grade 70 is often used in manufacturing of large pressure vessels that are subjected to high pressure and temperature, but was verified that its mechanical resistance is decreased when submitted to a tension relief heat treatment. By experience it was defined that before mechanical conformation of the head of a large pressure vessel, the steel should be submitted to a stress relief heat treatment in order to facilitate the mechanical conformation, but there is no quantitative analysis to prove this method and study its possible risks. In the present work the steel A-516 Grade 70 demonstrated a decrease of its mechanical resistance when submitted to a stress relief heat treatment, but keeping above the minimum limit defined in the literature. By other side its ductility was substantially increased, being possible to deduce that the stress relief heat treatment before mechanical conformation is a viable e recommended technique, but with reservations. With the data acquired during the fabrication e preparation of the specimen and the result of the tests, it was possible to elaborate a welding procedure that provides the same results obtained in this present work

A qualidade da interação entre pares e a implantação de um ambiente sociomoral a partir da literatura infantil

The present research, of a qualitative nature, aimed to check possible changes in the relations between pairs after the implantation of a work with children’s literature. The work was part of a teacher training project whose proposal is the deployment of a cooperative sociomoral environment in the classroom. The sample was composed of 250 students (boys and girls) 7-10 years, students of elementary school I in municipal education networks in São Paulo State. The method used was the application of a questionnaire in two stages: the pre-test, prior to the implementation of the project, and the post-test, carried out with the children after the end of the work. By means the questionnaire, that contained questions on three main themes – friendships at school, the systematic group work and the feelings expressed with respect to the school –, the children were asked about the quality of the relations between pairs. The data obtained have gone through a quantitative and qualitative analysis, being statistically proven. Eventually, the results of the two stages of the questionnaire were compared, indicating a better quality in interpersonal relations experienced in school after the implementation of the work with children’s literature.

Diagnóstico e planejamento em cirurgia parendodôntica: utilização da tomografia cone beam

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.

Subconjunctival and topical application of recombinant tissue plasminogen activator in rabbits

To quantify fibrin degradation products after topical and subconjunctival administration of recombinant tissue plasminogen activator in rabbits. Methods: Fibrin formation was induced in the anterior chamber in 25 rabbits. Subsequently, five rabbits received an injection of r-TPA (positive control) in the anterior chamber, another 10 received a subconjunctival injection of r-TPA, and the remaining 10 received instillations of topical r-TPA. Afterwards, samples of aqueous humor were collected and semi-quantitative analysis of fibrin degradation products (FDP) was performed. Results: No statistical differences were noted between the treatment and control groups at any time point. Fibrin degradation products semi-quantification showed statistical improvement in the control group and the subconjunctival group. Conclusion: Fibrin degradation products were observed in the anterior chamber after subconjunctival administration of r-TPA. However, it was probably not sufficient to cause fibrin degradation. Topical r-TPA did not effectively absorb anterior chamber fibrin.

Validation of analytical methodology for quantification of cefazolin sodium by liquid chromatography

A reversed-phase high performance liquid chromatography method was validated for the determination of cefazolin sodium in lyophilized powder for solution for injection to be applied for quality control in pharmaceutical industry. The liquid chromatography method was conducted on a Zorbax Eclipse Plus C18 column (250 x 4.6 mm, 5 μm), maintained at room temperature. The mobile phase consisted of purified water: acetonitrile (60: 40 v/v), adjusted to pH 8 with triethylamine. The flow rate was of 0.5 mL min-1 and effluents were monitored at 270 nm. The retention time for cefazolin sodium was 3.6 min. The method proved to be linear (r2 =0.9999) over the concentration range of 30-80 µg mL-1. The selectivity of the method was proven through degradation studies. The method demonstrated satisfactory results for precision, accuracy, limits of detection and quantitation. The robustness of this method was evaluated using the Plackett–Burman fractional factorial experimental design with a matrix of 15 experiments and the statistical treatment proposed by Youden and Steiner. Finally, the proposed method could be also an advantageous option for the analysis of cefazolin sodium, contributing to improve the quality control and to assure the therapeutic efficacy

Morte, família e a compreensão fenomenológica: revisão sistemática de literatura

The phenomenological research aims to understand how human beings mean their experiences and allows a detailed investigation of issues related to human life. In order to understand how the death experience within the family has been addressed by studies within phenomenological research perspective, a systematic review of literature was performed based on abstracts indexed in Lilacs, PEPsic, Medline e PsycInfo, by means of the intersection of the keywords: family, death, and phenomenology. Overall, 54 papers were found. Initially, all the papers were subjected to a quantitative analysis, after which 15 were selected for qualitative analysis. The results indicated that studies with grounding in phenomenology addressed three major themes: the experiences, meanings and coping with grief and loss, the family’s relationship with the terminally ill patient, and the experiences of families facing sudden death.

Plantas medicinais: indicação popular de uso no tratamento de hipertensão arterial sistêmica (HAS)

The aim of this study is to investigate the spontaneous use of medicinal plants by volunteer patients in the treatment of hypertension and to determine the most used plants in this situation. Data were collected through a questionnaire and a semi-structured guided interview applied to patients from a health center in the Midwest region of the state of Sao Paulo, Brazil. Quantitative analysis identified a high number of hypertensive patients spontaneously using herbal treatment. The referred plants were identified by the Herbarium Botu and researched in the literature as to their therapeutic actions. The biggest mistake was observed in the misuse of the Bilberry for the treatment of hypertension, which reveals that health professionals and the community in general should be more careful. As a result we have published an informative booklet, with emphasis on hypertension concepts and on the use of medicinal plants as an alternative therapy method for this disease in order to provide scientific knowledge and scientific research evidence to this practice.

A representação temática da tecnologia nos jornais brasileiros e sua configuração mercadológica diante de uma perspectiva de conceito social

This article is part of the result of the Master's thesis of the author, guided by coauthor, and presents a theoretical and conceptual reflection on the representation of Technology in thematic sections Technology in four Brazilian newspaper sites. The fundamental hypothesis is that these editorials prioritize issues that meet market interests of companies in the sector and may be leaving out important social and cultural issues to the understanding of the relationship between technology and society. The study is itself oriented by prospects of journalistic theming and specialized journalism, from a quantitative analysis involving the websites from newspapers of Technology sections O Estado de S. Paulo, Folha de S. Paulo, Gazeta do Povo and Correio Braziliense. The study confirms the hypothesis that representation of Technology in newspapers is primarily the marketing, have not corresponding to an expectation of social and cultural concept. In addition, it is noticed that the editorial in question do not have specialized journalism characteristics, despite of potential generated by thematic segmentation.
