Circulação atmosférica e precipitação pluviométrica na Bacia do Itajaí - SC: um estudo climatológico aplicado

The work is guided by the detailing of the Itajaí river basin, SC, rainfall dynamics at the annual, seasonal and monthly levels, allowing us to identify different responses that each location gives to the regional atmospheric circulation, particularly the rainfall. In this sense, we are aiming at approaching the concept of rhythm, which must be obtained at the daily level. The analysis at different climate scales was possible through isohyetal maps, trend lines, and Schroeder pluviographs. Moreover, we established the flow rate of the air masses by means of the Venn diagram. This data made it possible to assess the behavior of rains on that site and the reason why it is the stage of major flooding, as occurred in November 2008. The relatively mountainous topography combined with the frequent invasions of the Atlantic Polar Front, which often stop over the region, generate events of that magnitude, with high volumes accumulated in short periods of time. Such extreme events reinforce the idea of the search for the succession of types of weather to the detriment of averages that tend to abstract the reality

Estudo da dose efetiva, razão sinal-ruído e razão contraste-ruído em tomografia computadorizada de múltiplos detetores

Since discovery, computed tomography is a widely used diagnostic modality. However, this modality imparts relatively high doses to the patients and with fast technological advancement, it is necessary optimize the doses used and ensure the quality of the images through a quality assurance program. This work intended to compare Computed Tomography Dose Index (CTDIW) and effective dose with components of image quality: the Contrast-to-Noise Ratio (CNR) and Signal-to-Noise Ratio (SNR), and a quality factor (Q) deduced by the Rose model for two groups of computed tomography units. The first group was composed by equipments with 10 up to 16 slices and the second one presented 40 up to 320 slices detectors, for the protocols of head and abdomen. It was realized a comparison between different selectable parameters in the protocol of a Philips Brilliance 16, too. The results of the first group to CTDIW, effective dose, SNR and CNR showed variations of 28%, 33%, 37% and 32% respectively for head protocol, and 21%, 27%, 43% and 37% respectively for abdomen protocol. The results of the group 2 to CTDIW, effective dose, SNR and CNR showed variations of 15%, 26%, 36% and 34% respectively for the head protocol, and 8%, 13%, 50% and 60% respectively for abdomen protocol. The comparison between both groups demonstrated similar levels of doses impartation to patients though having so many different configurations, if the uncertainties associated with this measurement were considered. The results of the comparison between different parameters in the Philips Brilliance 16 scanner were in agreement with expected

Metodologia de determinação das curvas de probabilidade de falha S-N-P para uma liga de aluminio submetida a diferentes tratamentos termicos de solubilização e precipitação

The approach of the subject matter in this work relies on the fact that the reliability of methods for performance analysis of materials proves critical for the result. This work focused on the development and presentation of the methodology for lifting probability curves for fatigue test (SN) according to standard E739, this focus is justified by the fact that the results in fatigue test show considerable dispersion making it difficult to reading and interpretation of data, this dispersion arises because the phenomenon of rupture is strongly influenced by internal characteristics of the material, we can then have much data ranging from test to test. Thus we set out originally for a brief study of aluminum alloys in question, as well as the treatments to which they were subjected. We also studied the behavior of materials when subjected to cyclic loading, which configures process of fatigue failure, and even fatigue test method in question. This statistical analysis is based on the ASTM E739 standard, so its contents was studied in detail so that we could present in detail the methodology and raise SN curves for different aluminum alloy 7012 subjected to fatigue test. Data were collected from tests conducted in the department of materials from two samples of aluminum alloy 7012 solubilized and precipitated by different time intervals and assayed temperature fatigue-type traction-compression, these data were then analyzed and used to survey curves using the base as E739. After lifting the curve analyzed the characteristics of the test samples and their correlation with the test results. We confirmed the effectiveness of the method of statistical analysis by ASME E739, which allowed the reading of data without this method would be very difficult to have a reading and comparison of the results for the two types...

Caracterização físico-química e microbiológica de diferentes amostras de uma precipitação coletada e armazenada após passagem por telhado

The decreasing availability of drinking water is a problem that has existed for a long time and continues to be aggravated, especially by the increase in population and pollution of water resources. Due to the need to find alternatives in order to ensure water supplies in sufficient quantity and quality for consumption by populations, rainwater collection arises as an alternative. The present study was developed in Ipeúna-SP, consisting of an experimental system of collection and storage of rainwater on the roofs of buildings. Samples of the same precipitation, differentiated through the initial disposal and treatment of the collected water, were stored during a period of six months and monitored through physical, chemical and microbiological analyses. With the results, the qualitative characteristics of the stored precipitation were found, the main differences among the samples were identified and the needs of treatment were studied.

Relações entre os acidentes de trânsito e a precipitação na área urbana de Rio Claro (SP)

Thus, the aim of this work was to compile a database of traffic accidents recorded for the 2° Sub-Grouping of the Fire Department of the city of Rio Claro (SP) during the years 2008 to 2010 and related to rain. The result allowed profiling of traffic accidents, recognize critical areas and correlate the rain as an interference factor in the occurrence of traffic accidents in Rio Claro (SP)

A empatia, a sensibilização e a formação de professores do ensino público para uma inclusão efetiva de alunos com necessidades educacionais especiais

Special education and inclusion of students with Special Educational Needs (SEN) in regular classrooms of public schools has being widely discussed in academic and political areas. From Salamanca Declaration signed in 1994, which established that the education of people with special needs should be guaranteed by public system, being offered within regular classrooms said. Along the inclusion process, has been observed an increasingly difficult for teachers to work with these special students. This difficulty comes from an incomplete or inadequate formation, resulting in an education that is not always inclusive. The present work aims to investigate what are the motivational factors that lead teachers, working in public schools, to seek continuing courses of formation in specialized educational services, and what are the possible impediments that eschew them from seeking such courses. Data were collected through questionnaires given to elementary school teachers, from public schools in the city of Rio Claro- SP. With their answer, it could be identified what are the motivational factors of the quest for continuing formation, as well as facts that obstruct this specialization. It could be observed that there is a need for constant training of the education professionals, for them to be able to appropriate of the inclusion as a pedagogical approach, not just a law and far from reality

Efeito de dose efetiva mínima e dose não tóxica de 5-Fluorouracil e Leucovorina sobre a atividade de células dendríticas humanas e sobre a imunogenicidade de células de câncer colorretal

A quimioterapia antitumoral convencional, baseada na aplicação da dose máxima tolerável de drogas antineoplásicas, está comumente associada com mielossupressão e causa diminuição da viabilidade e número de células dendríticas (DCs), principais células apresentadoras de antígenos (APCs) do sistema imune. Uma alternativa para limitar os efeitos tóxicos desses agentes é a quimioterapia metronômica, baseada na administração das drogas em doses baixas e frequentes que, entre outros aspectos, melhora a eficácia antitumoral pela inibição da angiogênese no sítio do tumor. Estudos prévios do grupo indicam que doses ultrabaixas de determinados agentes antineoplásicos modulam positivamente o estado de ativação e as funções das células dendríticas, sugerindo que a associação entre vacinas de DCs e quimioterapia metronômica possibilitaria a estimulação da resposta imune, ao mesmo tempo em que as células tumorais sofrem o efeito dos agentes antineoplásicos em doses ultrabaixas. Assim, hipotetizamos que o uso de 5-Fluorouracil e Leucovorina, drogas de escolha para o tratamento do câncer colorretal, em dose efetiva mínima ou dose ultrabaixa não tóxica, poderia modular positivamente as DCs humanas e potencializar a imunogenicidade de células tumorais, além de torná-las mais sensíveis à ação de linfócitos T citotóxicos. Desse modo, o presente estudo tem o objetivo de avaliar o efeito in vitro da dose efetiva mínima e dose não tóxica de 5-Fluorouracil e Leucovorina sobre as funções de células dendríticas humanas e sobre a imunogenicidade de células de câncer colorretal humano da linhagem HT-29. Com esse propósito as DCs humanas foram sensibilizadas com lisatos de células tumorais pré tratadas com as doses previamente determinadas das drogas e avaliadas quanto à capacidade de apresentação de antígenos e indução de linfócitos T citotóxicos...

Imagens de satélite na análise da relação entre queimadas, aerossóis atmosféricos e precipitação

The direct and indirect effects of atmospheric aerossols in the amazonic climate have been focus of many published. This work aims to analyze a possible relation among Burns, atmospheric aerossols and precipitation above South America. It uses the avaluable data from the satellites AQUA/TERRA and TRMM and the images furnished by NOAA and GOES. These analysis can provide some explanations about the effects of emission of aerosols by burns on the composition of atmosphere and cloud formation, mainly in Amazon. We use the Aerosol Optical Depth (AOD) from MODIS/TERRA-AQUA, burns index from CPTEC and rain rate from TRMM. The data we use were obtained from 2000 until 2012. The study is divided in two parts. In the first one, it was performed a quantitative analysis between number of burns and aerosols emission. It was identified a great variability in space and time of the AOD on South America. On the north, northeast and center-west, the AOD is significant during the winter period, with peak on August and September. The southeast is affected by aerosols from center-west due to the dynamical transport. In the second part, it was evaluated the relation between AOD and precipitation in a 13-year period. The statistical analysis shows up a negative correlation of 0.72 between August and October, on Legal Amazon. These result indicate an inverse relation between AOD and rain rate. The other months present not significant correlation. These results are in a good agreement with the literature, in which in-situ methods were applied or combined with satellites data. The increasing of aerosols concentration in the atmosphere are reinforced during drier years. It can affect the increasing process of water drops, decreasing the precipitation. We also verified higher values of AOD (0.25 - 0.3) during years with El Niño, than the climatologically average (~0.15 - 0.2), ... (Complete abstract click electronic access below)

Variabilidade da precipitação na Unidade de Gerenciamento de Recursos Hídricos do médio Paranapanema

Analysis of variability of rainfall UGRHI-17 is important because it is located in an area of agriculture. This importance is through a better dialogue between research and farmers, who can see this, an analysis of events that impact your direct planting. Noting the periodic occurrence of these events, agriculture can be prevented by protecting your planting and ensuring a good harvest. The analysis and observation of the entire region is through the location of the stations, which allow a more complete analysis if they are well scattered throughout the unit. Through calculations parse wet and dry years, and this work will be given emphasis to the wet years. They presented the climatological average above average extracted for all seasons. These wet years are generally associated with events such as El Niño and the intensification of SACZ. For these years, was also observed the spatial distribution of rainfall through isolines. How to deal with regional data, the Geostatistics was a resource used in this work to make the analysis more complete and closer to the actual data from the wide year-to-interannual scale. Their adoption is in the preparation of contour, making the spatial distribution more accurate.

Análise sazonal e espacial da precipitação pluvial na bacia hidrográfica do rio Ivaí, Paraná

Climate variability and therefore the rainfall is often cited today, in times to speak of "global change", "global warming", "anthropogenic disasters," among other terms related to climate issues, which may cause floods and disasters that affect entire regions. In this sense, the seasonal rainfall and its extremes in the basin of Ivaí river, which has a drainage area of approximately 36 000 km2, covering a length of 680 km, located in the State of Paraná between coordinates 22 º 54'S 25 ° 44'S and 55 44'W to 52 º 42'W, were analyzed. Influence of rainfall for the man occupation is undeniably important, not less important is the role that this issue poses to the climate abiotic and biotic environment, because the dynamic relations between the fauna and flora is directly related to the availability of water in system (in this case, rain). The methodological procedures used during the research focused on statistical analysis of rainfall series daily, monthly and yearly, provided by the Superintendence of Water Resources Development and Environmental Protection Agency - SUDERHSA, an agency linked to the government of Parana. The analysis period chosen was from 1975 to 2005, with 38 stations for data collection, distributed evenly across the search area. The standard rainfall in the basin is explained mainly by convective processes in the summer (wet season) and front system causing more homogeneous rainfall over the basin (dry season). What is well marked is the occurrence of maximum rainfall in the years 1983 and 1997 (El Niño) and minimal in the years 1977, 1985 and 1988 (La Niña). Finally, although the study area have undergone a significant change in your landscape for over thirty years, this study indicates no significant interference in rainfall.
