O uso do geoprocessamento para mapear as áreas verdes urbanas como indicador de qualidade ambiental no município de Americana/SP

The style of life in the cities deprives the man of the contact with nature. As a way to escape from the turbulent reality of the urban system, the urban planning provides areas that allow the contact between man and nature like botanical gardens, parks, leafy squares, etc. These places, through specific analysis, are also called green areas. Thus, the main purpose of this research is to outline and analyze, through geoprocessing techniques, green areas of Americana, São Paulo considering them as indicators of urban environmental quality. This evaluation will be based on the methodology adapted by Bargos (2010) where products of remote sensing were used (aerial photos and satellite images) and it will be also based on field work and calculation of the amount of green areas. The software ESRI ArcGIS® will be used to create thematic maps connected with city’s green areas. Based on the results achieved in this study, it’s expected to contribute to the government of the city of Americana in order to provide benefits of analysis for decision makers in the context of urban planning aiming an improvement in the urban environmental quality, thus benefiting its entire population

O conto de Rubens Figueiredo em As palavras secretas: conto contemporâneo

We work with the storybook, As Palavras Secretas, written by carioca Rubens Figueiredo. We treat, then, the Brazilian contemporary tale. For we study the writer’s fiction, first we met a critical bibliography about the narrative and a set of diverse texts: reports, articles, press releases, interviews and essays about the author’s work. We discourse characteristics and the compositional elements of each story and noticed that they are full of symbolism and various elements that they are recurrent. Some of these narratives deal with fragmentation of the man who, indeed, is a very striking feature in the actual Brazilian tale. We meet, then, with characters who feel the need to simulate an identity and that, therefore, coexist with a strong inner conflict. Three of the tales include the unlikelihood of that work, and present, therefore, elements that escape from reality. Finally, Rubens Figueiredo, in As Palavras Secretas, presented us narratives rather elongated, unlike what was ordinary in the category of the tale, which it usually consists of a short extension narrative

Vagueza e indeterminação na noção de história de Arendt

The purpose of this paper is to present the thought of Hannah Arendt on the historical narrativa, as the reading of theories of cognition and the sign of Peirce. It is not categorial parallelism, but to highlight some approximation in order to conceive the thought and language. For both, communication is important in the formation of your thoughts. While one has broader interests, the other directs its efforts to human society, politics and history. However, both authors agree on the fallible nature o four opinions, and reject the traditional philosophies, advocates of transcendental schemes, which are imposed, silencing the experience, the source o four opinions. The proposal, to seek the experience, the origino f opinions, ou interpretations, excluding transcental rules, but the community is what gives the character of the narrative indeterminacy. They do not escape from the temporal and social factors. Therefore, are subject to what gives them legitimacy, ie, freedom.

Escape depth of secondary electrons from electron-irradiated polymers

Measurements on polymers (Teflon FEP and Mylar) have shown that the secondary electron emission from uncharged surfaces exceeds that from surfaces containing a positive surface charge. The reduced emission of charged surfaces is due to recombination between electrons undergoing emission and trapped holes within the charged layer. During the experiments the surface of the material was kept at a negative potential to assure that all secondary electrons reaching the surface from within the material are actually emitted. An analysis of the results yielded the maximum escape depth of the secondary electrons, and showed that the ratio of the maximum escape depth of the secondaries from Mylar to the maximum escape depth from Teflon is almost the same as the ratio of the corresponding second crossover energies of this polymers.

Serotonergic neurons in the median raphe nucleus regulate inhibitory avoidance but not escape behavior in the rat elevated T-maze test of anxiety

Rationale: A wealth of evidence supports the involvement of the serotonergic neurons of the median raphe nucleus (MRN) in anxiety. However, it is presently unclear whether serotonergic pathways arising from this nucleus play distinguishing regulatory roles in defensive behaviors that have been associated with specific subtypes of anxiety disorders. Objectives: To evaluate the role of the MRN serotonergic neurons in the regulation of two defensive behaviors, inhibitory avoidance and escape, which have been related, respectively, to generalized anxiety and panic disorders. Methods: Male Wistar rats were submitted to the elevated T-maze test of anxiety after intra-MRN administration of drugs that either non-selectively or selectively change the activity of the serotonergic neurons. Results: Intra-MRN injection of FG 7142 (0.04 and 0.08 nmol) and kainic acid (0.03 and 0.06 nmol), drugs that non-selectively stimulate the MRN serotonergic neurons, facilitated inhibitory avoidance acquisition, but impaired escape performance. Microinjection of muscimol (0.11 and 0.22 nmol), a compound that non-selectively inhibits the activity of the MRN serotonergic neurons, impaired inhibitory avoidance and facilitated escape performance. Both kainic acid and muscimol also changed rat locomotion in the open-field test. Intra-MRN injection of 8-OH-DPAT (0.6-15 nmol) and WAY-100635 (0.18-0.74 nmol), respectively an agonist and an antagonist of somatodendritic 5-HT1A receptors located on serotonergic neurons of the MRN, only affected inhibitory avoidance-while the former inhibited the acquisition of this behavior, the latter facilitated it. Conclusion: MRN serotonergic neurons seem to be selectively involved in the regulation of inhibitory avoidance in the elevated T-maze. This result supports the proposal that 5-HT pathways departing from this nucleus play an important role in anxiety processing, with implications for pathologies such as generalized anxiety disorder.

Ice as a vehicle for diarrheagenic Escherichia coli

In a recent study of the microbiological quality of commercial ice, 50 Escherichia coli isolates belonging to different serotypes were found. The potential hazard from these isolates was examined by testing their adherence patterns ill HeLa cells and searching for the presence of DNA sequences related to E. coli virulence properties. Twelve potentially diarrheagenic isolates were found and classified as enteroaggregative E. coli (EAEC) based oil their ability to produce aggregative adherence to HeLa cells. The remaining isolates were devoid of the virulence properties searched for. The EAEC isolates belonged to 10 different serotypes, among which O128ab:H35 is often found in diarrheic feces. None of these isolates reacted with a specific EAEC DNA probe or carried any of the known EAEC virulence genes. These data indicate that ice may be all important vehicle for transmission of enteropathogens, especially of the EAEC group. (C) 2003 Elsevier B.V. All rights reserved.

Persistent Pleuropulmonary Air Leak Treated with Autologous Blood: Results from a University Hospital and Review of Literature

Background: Persistent air leak after pulmonary resection is a difficult complication for thoracic surgeons to manage. Objectives: To show the results of our experience treating persistent pleuropulmonary air leak with autologous blood and review the literature on this specific method of treatment. Methods: Retrospective study of patients with persistent aerial pleuropulmonary fistula treated with autologous blood. The patient's own blood was collected from a peripheral vein and directly introduced through the pleural drain. An inverted siphon was located in the drainage system to avoid prolonged clamping of the drain. This siphon impeded blood return but not air escape. Results: Between January 2001 and August 2008, 27 patients were treated by the above method. Patient age ranged from 2 to 74 years, and 78% were male. Each procedure used a mean quantity of 92 ml blood. Mean persistent air leak time before pleurodesis was 10.6 days and mean time to fistula resolution after pleurodesis was 1.5 days. Twenty-three (85%) patients had persistent pleuropulmonary air leak closed with the above procedure. Conclusion: Treating persistent pleuropulmonary air leak with autologous blood is promising, but further studies are required to quantify its real effectiveness. Copyright (C) 2009 S.

Occurrence of coagulase-positive Staphylococcus in various food products commercialized in Botucatu, SP, Brazil and detection of toxins from food and isolated strains

The aim of this work was to assess the microbiological quality of commercialized desserts, sandwiches and finger food in Botucatu, SP, for human consumption. A total of 172 food samples were analyzed for fecal coliforms and coagulase-positive Staphylococcus and 69 (40.1%) were in disagreement with the standards established by Decree No. 12 (Brazilian Food Sanitation Standard, 2001). Coagulase-positive Staplylococcus was isolated from 26 (15.1%) samples. Toxins were not isolated directly from foods but 27 (54%) coagulase-positive Staphylococcus strains were enterotoxigenic, and toxin type C was the most frequently detected. These results suggest that these products may act as an important vehicle of transmission for well-established pathogens. (c) 2006 Elsevier Ltd. All rights reserved.

Release and diffusion of hydroxyl ion from calcium hydroxide-based medicaments

The release and diffusion of hydroxyl ions (OH-) of calcium hydroxide (Ca(OH)2)-based intracanal medications may be affected by the association with other substances. The aim of this study was to evaluate the diffusion of OH- ions through root dentin by the medications: G1, Ca(OH)2/saline; G2, Calen; G3, Calen/camphorated p-monochlorophenol (CMCP); and G4, Calen/0.4% chlorhexidine (CHX). Root canals from bovine teeth were prepared in a standardized manner. A cavity until dentin was prepared in the middle third of the root surface of each specimen. The external surface of the root was made impermeable using a layer of adhesive, except the prepared cavity. The root canals were filled with different medications, and teeth were individually stored in flasks containing 10 ml distilled water at 37 degrees C. The water pH was measured at 1, 3, 7, 14, 21, 30, and 60 days. Data obtained were subjected to anova and Tukeys tests. Increase in pH was observed at 3 days for Calen/CHX and from 7 to 14 days for the other mixtures. Calen paste promoted pH increase up to 21 days. Calen/CMCP had the highest pH up to 21 days, and all groups had similar results at 30 days. At 60 days, the greatest pH values were observed for Calen/CMCP and Calen alone. All different formulations of Ca(OH)2-based medications tested release hydroxyl ion that can diffuse through the dentin.
