Este estudo busca analisar os vínculos jornalísticos do rádio com a cidade de Bauru, situada na região central do Estado de São Paulo. Para isso, buscou-se contextualizar a evolução histórica do município com o desenvolvimento desse veículo de comunicação. Dessa forma, nota-se a importância de Bauru na história do rádio brasileiro e, em contrapartida, do próprio rádio no avanço e no desenvolvimento da cidade. Desde a primeira emissora instalada no município, a Bauru Rádio Clube (também conhecida pelo prefixo PRG-8), verifica-se que houve tentativas de buscar a proximidade com o público ouvinte. Como forma de embasar essas afirmações, realizou-se um estudo do caso da rádio Jovem Auri Verde, que transmite em amplitude modulada (AM)

Over the last decades, new dynamics of urban landscape production and transformation have influenced on the character of their open spaces. Processes such as the fragmentation and the dispersion of the urban fabric, which include the fast proliferation of gated communities, have contributed to the increase of insecurity and abandonment of the free access open spaces, damaging the social dynamics of public character. This paper aims to highlight the benefits that these spaces could provide for the city if, instead of being treated as isolated fragments, they were thought of as a system, that is, as a set of elements integrated with the urban planning strategies. From the results of a research carried out in the city of Bauru-SP, are analyzed the transformations that open spaces have been suffering owing to the new forms of organization of the urban fabric with tendencies to privatization, especially in recent urban sprawl areas.

RESUMO As mastites são inflamações agudas ou crônicas da glândula mamária, caracterizadas por alte-rações físicas, químicas e bacteriológicas no leite. O leite ovino tem ocupado uma importância cada vez maior no mercado, podendo ser utilizado na produção de queijo e outros derivados, contribuindo para o aumento da receita do produtor rural. Entretanto, a mastite pode determinar redução, tanto na quantidade quanto na qualidade do leite produzido, levando à redução do ganho de peso dos cordeiros e causando aumento da mortalidade nos animais. Ressalta-se ainda o aspecto de saúde pública, pela redução do nível de nutrientes, assim como a intensa multiplicação microbiana que pode ocasionar diarreias e outras zoonoses. Pretendeu-se com este trabalho avaliar a frequência de casos de mastite em 159 ovelhas procedentes de vinte pequenas propriedades localizadas em Bauru, SP, e região. Das 309 amostras colhidas, em 97 (31,4%) foram isolados micro-organismos do gênero Staphylococcus sp., sendo 27,5% Staphylococcus sp. coagulase negativos e 3,9% Staphylococcus sp. coagulase positivos. Dos 177 isolamentos, 97 (54,8%) foram representados pelo gênero Staphylococcus, sendo 57 (58,8%) obtidos em cultura pura e 40 (41,2%) em associação. A maioria dos agentes isolados foi sensível aos antimicrobianos utilizados no teste. Assim, pôde-se verificar o isolamento de micro-organismos contagiosos, como Staphylococcus sp. coagulase negativo e positivo, sendo que, assim como na bovinocultura leiteira, medidas de profilaxia para obtenção higiênica do leite são de extrema importância para adquirir-se um produto final de qualidade, e seguro do ponto de vista microbiológico e alimentar.

The Bauru Basin (Upper Cretaceous) accumulated an essentially sandy continental sedimentary sequence. In a first desertic phase the basaltic substratum was covered by a widespread and homogeneous aeolian sand unit with minor loess intercalations. The substratum relief favored the formation of an endorheic drainage system under semi-arid climate, a process that started the development of the Araçatuba Paleoswamp. The palustrine deposits (Araçatuba Formation) comprise siltstone and tipically greenish gray narrow tabular strata of sandstone cemented by carbonate. Moulds and gypsite and dolomite pseudomorphs were identified. The moulds seem to be genetically associated with desiccation cracks, root marks and climbing ripple lamination levels, that, on the whole, indicate calm shallow saline waters undergoing phases of subaerial exposition. At the boundaries of the study area, sand units may exhibit sigmoidal features and convolute bedding structure, which is characteristic of marginal deltaic deposits. The Araçatuba Formation is enclosed in and later overlaid by the aeolian deposits of the Vale do Rio do Peixe Formation.

This study was done to determine compactness of soil strata in the urban area of Bauru, central São Paulo State using standard penetration test (SPT) and seismic refraction methods. Frequency distribution within boreholes was measured every meter to a depth of 30 meters. The geometric mean of standard penetration test values was computed every meter. A biplot graph showing the relationship of SPT with depth indicates soil stratification. In addition, five sections of seismic refraction values, which also indicate the compactness of soil strata, were obtained. A comparison of the two methods shows significant correlation between the results obtained from each.

The aim of this work is to study the local impact on the upper troposphere/lower stratosphere air composition of an extreme deep convective system. For this purpose, we performed a simulation of a convective cluster composed of many individual deep convective cells that occurred near Bauru (Brazil). The simulation is performed using the 3-D mesoscale model RAMS coupled on-line with a chemistry model. The comparisons with meteorological measurements show that the model produces meteorological fields generally consistent with the observations. The present paper (part I) is devoted to the analysis of the ozone precursors (CO, NO x and non-methane volatile organic compounds) and HO x in the UTLS. The simulation results show that the distribution of CO with altitude is closely related to the upward convective motions and consecutive outflow at the top of the convective cells leading to a bulge of CO between 7 km altitude and the tropopause (around 17km altitude). The model results for CO are consistent with satellite-borne measurements at 700 hPa. The simulation also indicates enhanced amounts of NO x up to 2 ppbv in the 7-17 km altitude layer mainly produced by the lightning associated with the intense convective activity. For insoluble non-methane volatile organic compounds, the convective activity tends to significantly increase their amount in the 7-17km layer by dynamical effects. During daytime in the presence of lightning NO x, this bulge is largely reduced in the upper part of the layer for reactive species (e.g. isoprene, ethene) because of their reactions with OH that is increased on average during daytime. Lightning NO x also impacts on the oxydizing capacity of the upper troposphere by reducing on average HO x, HO 2, H 2O 2 and organic hydroperoxides. During the simulation time, the impact of convection on the air composition of the lower stratosphere is negligible for all ozone precursors although several of the simulated convective cells nearly reach the tropopause. There is no significant transport from the upper troposphere to the lower stratosphere, the isentropic barrier not being crossed by convection. The impact of the increase of ozone precursors and HO x in the upper troposphere on the ozone budget in the LS is discussed in part II of this series of papers.

Simulations of overshooting, tropical deep convection using a Cloud Resolving Model with bulk microphysics are presented in order to examine the effect on the water content of the TTL (Tropical Tropopause Layer) and lower stratosphere. This case study is a subproject of the HIBISCUS (Impact of tropical convection on the upper troposphere and lower stratosphere at global scale) campaign, which took place in Bauru, Brazil (22° S, 49° W), from the end of January to early March 2004. Comparisons between 2-D and 3-D simulations suggest that the use of 3-D dynamics is vital in order to capture the mixing between the overshoot and the stratospheric air, which caused evaporation of ice and resulted in an overall moistening of the lower stratosphere. In contrast, a dehydrating effect was predicted by the 2-D simulation due to the extra time, allowed by the lack of mixing, for the ice transported to the region to precipitate out of the overshoot air. Three different strengths of convection are simulated in 3-D by applying successively lower heating rates (used to initiate the convection) in the boundary layer. Moistening is produced in all cases, indicating that convective vigour is not a factor in whether moistening or dehydration is produced by clouds that penetrate the tropopause, since the weakest case only just did so. An estimate of the moistening effect of these clouds on an air parcel traversing a convective region is made based on the domain mean simulated moistening and the frequency of convective events observed by the IPMet (Instituto de Pesquisas Meteorológicas, Universidade Estadual Paulista) radar (S-band type at 2.8 Ghz) to have the same 10 dBZ echo top height as those simulated. These suggest a fairly significant mean moistening of 0.26, 0.13 and 0.05 ppmv in the strongest, medium and weakest cases, respectively, for heights between 16 and 17 km. Since the cold point and WMO (World Meteorological Organization) tropopause in this region lies at ∼ 15.9 km, this is likely to represent direct stratospheric moistening. Much more moistening is predicted for the 15-16 km height range with increases of 0.85-2.8 ppmv predicted. However, it would be required that this air is lofted through the tropopause via the Brewer Dobson circulation in order for it to have a stratospheric effect. Whether this is likely is uncertain and, in addition, the dehydration of air as it passes through the cold trap and the number of times that trajectories sample convective regions needs to be taken into account to gauge the overall stratospheric effect. Nevertheless, the results suggest a potentially significant role for convection in determining the stratospheric water content. Sensitivity tests exploring the impact of increased aerosol numbers in the boundary layer suggest that a corresponding rise in cloud droplet numbers at cloud base would increase the number concentrations of the ice crystals transported to the TTL, which had the effect of reducing the fall speeds of the ice and causing a ∼13% rise in the mean vapour increase in both the 15-16 and 16-17 km height ranges, respectively, when compared to the control case. Increases in the total water were much larger, being 34% and 132% higher for the same height ranges, but it is unclear whether the extra ice will be able to evaporate before precipitating from the region. These results suggest a possible impact of natural and anthropogenic aerosols on how convective clouds affect stratospheric moisture levels.
