The cities have grown significantly and in a disorderly way, without minimum urban planning, which has provoked to urban and environmental problems. Among many consequences of this growth, high soil waterproofing features highlight due to the consequences it brings, as the occurrence of floods, floods and spread of waterborne diseases. Much of the runoff of rainwater comes from the paved soil, and is possible observe that about 20% of the urban area of a city is paved with the function of serving as circulation area of pedestrians or vehicles, according to the Federal Law No. 6766 of 19 December 1979 which provides for the division of urban soil and other measures (BRAZIL, 1979). In this context the objective of this research is the study of the effects of the spaces of Circulation and Permanence Pedestrians (ECPP) on the management of rainwater, with the empirical object one experimental watershed located on the campus of UFSCar in São Carlos / SP, and two areas urbanized in the city of Sao Jose do Rio Preto / SP. For this, it was made the identification of different types of floors, characterization and hydrological efficiency, research in academic papers and catalogs of suppliers, and analyze the areas and conditions of ECPPs within the perimeters of study under the hydrologic context, design, implementation, and maintenance costs. The findings evaluate the effects of ECPPs on the management of rainwater, and compare the results between the three ECPPs. These results show that the ECPP located in USFCar contributes 6% to runoff, while the ECPP Pedestrian street 35% and ECPP Neighborhood 9% to project parties were adopted that destined runoff for grassed areas or permeable floors these scenarios would be 2% contribution to ECPP UFSCar, 0.2% of flow for ECPP Pedestrian Street and 2% for ECPP Neighborhood. So is possible reduce runoff using hydrologically functional floors, implementing and using the green areas as a design element, providing knowledge of data and materials that can contribute to new ways to plan and execute the ECPPs.
Diversidade de Dytiscidae (Coleoptera) em áreas úmidas do Rio Grande do Sul
(Universidade Federal de São Carlos, 2016-04-14) Gomes, Julia Gibertoni; Gessner, Alaíde Aparecida Fonseca; https://lattes.cnpq.br/8465752836529703; https://lattes.cnpq.br/0552130489388929
Beetles represented the largest group of animais but end up neglected in ecological studies and much of its wildlife has not described, mainly in tropical areas of great diversity. Dytiscidae, larger family of water beetles, prefers lentic environments, which can be divided according to their hydroperiod in permanent and periodic. The distribution of these ditiscidae were tested in this study in 104 wetlands of Rio Grande do Sul (RS) to detect differences in the composition of each hydroperiod, also serving as a survey of taxa occurring. Were sampled 1905 specimens from 21 genera with the first record in the state of genera Platynectes, Uvarus and Pachydrus. Multivariate Canonical Correspondence Analysis (CCA) found that only biome and hydroperiod influenced the fauna. The differencce of the beta diversity among hydroperiods was significant, showing that varied in composition with each other, and communities in more homogeneous perennial areas than those found in the periodic areas. Despite the difference of the faunal composition richness showed similar values when standardized by rarefaction curve and each hydroperiod presented exclusive taxa.
Utilização do complexo de rutênio cis- [Ru(bpy)2(NO2)(NO)](PF6)2) para reverter e/ou prevenir a disfunção endotelial na hipertensão arterial
(Universidade Federal de São Carlos, 2016-04-14) Vatanabe, Izabela Pereira; Rodrigues, Gerson Jhonatan; https://lattes.cnpq.br/6725550216586910; https://lattes.cnpq.br/3546552931158643
The endothelium is a monolayer of cells that extends on the vascular inner surface, responsible for the modulation of vascular tone. By means of the release of nitric oxide (NO), the endothelium has an important protective function against cardiovascular diseases, producing vasodilation by several mechanisms and generating a series of other effects, since at high concentrations it may produce toxic effects to the cells. However, endothelial dysfunction is characterized mainly by the decreased ability of endothelial cells to release NO, which may be due to reaction with superoxide anion (O2 -) and formation of peroxynitrite (ONOO-). In previous studies, it was found that ruthenium complexes can also inactivate O2 - and NO release. However, through vascular reactivity technique in aortic hypertensive and normotensive rats, and detection study of released NO in endothelial cells, the objective of this study was to evaluate the potential of the drug cis- [Ru(bpy)2(NO2)(NO)](PF6)2 as a pharmacologic strategy to reverse and/or prevent endothelial dysfunction found in the arterial hypertension model 2K-1C as well as to perform the pharmacological characterization of the dependent effects removal of O2 - and NO release induced by these drugs. Thus our major vascular reactivity results indicated that the BPY concentration of 0.1 μM was able to reverse the endothelial dysfunction present in the aortas of animals 2K-1C. Likewise, its positive control, Deta-NO in a specific concentration of 10 μM was able to reverse endothelial dysfunction, besides presenting a potentiating effect in the presence of endothelium. Furthermore, our results indicate that the lowest detection of NO in HUVECs treated with Ang. II, in addition to BPY compound occurs by the increased formation of O2 -, since in the presence of SOD there was an increased release of NO by BPY. Furthermore, it was observed that the BPY releases NO in solution in a sustained concentration-dependent form, where the presence of the endothelial cells increased and Angiotensin II reduces NO release, indicating a reduction or oxidation in BPY compound and also degradation of NO the formation of O2 -.
Epígrafes e diálogos na poesia de Machado de Assis
(Universidade Federal de São Carlos, 2016-04-14) Miasso, Audrey Ludmilla do Nascimento; Marques, Wilton José; https://lattes.cnpq.br/5763590592946918; https://lattes.cnpq.br/9186310434443185
On the epigraphs that accompany some poems of Crisálidas (1864), by Machado de Assis, there is the parade of authors such as Dante, Camões Heine and Homer. The same happens in the following books of poems, Falenas (1870) and Americanas (1875). The choice of these names reveals authors of Machado's library that accompanied him throughout his career and that influenced his composition so since his debut in the lyrics. Such names dialogue with Machado's poetry and help us to better understand the poetic composition of the author, and not only source of supply for the poems, but also in relationship with them on the issue of understanding of the work, giving them a new meaning.
Desenvolvimento de um instrumento para auditoria da caminhabilidade em áreas escolares
(Universidade Federal de São Carlos, 2016-04-14) Nanya, Luciana Mayumi; Sanches, Suely da Penha; https://lattes.cnpq.br/3857424839674606; https://lattes.cnpq.br/5668884386564690
Brazilian cities have shown a change in behavior in using the mode of transport used by children to access school. It can be associate this change to several factors, such as distance home-school and the quality of spaces for walking. Programs like Safe Routes to Schools seek to make the way to school safer for pedestrians and cyclists. Environmental audits help in the planning of Safe Routes to Schools identifying barriers and facilitators of the use of active modes of transportation. The objective of this research is to develop and validate an audit tool and evaluation of walkability into school for elementary schools in midsized cities. The application of audit tool developed was in the city of São José do Rio Preto - SP in 3 municipal primary schools located in different areas of the city. Two researchers conducted the audit. To assess the inter-rater reliability concordance percentages were used. The results show good reliability for the proposed audit instrument, with high percentages of agreement (above 80%). The results of the audit of the two researchers to calculate the Index Walkability area were considered. For comparisons between the means allocated to the segments and intersections was carried out ANOVA. Among the characteristics of the segments, it was found that at least one of the evaluated areas is different from the other (p <0.05). For the variables of signalized intersections not, the test indicates that, for the items width of the cross and accessibility, there is no statistical difference between the variables (p> 0.05) (researcher data 1). For the variables of signalized intersections not, (research data 2) the test indicates that, for the item width of the cross there is no statistical difference between the variables (p> 0.05). The application of the instrument can be an important tool in city planning process, in that it can identify opportunities and deficiencies in walkability surrounding schools to increase the safety and comfort of children during their walks to school.
