Turismo e meio ambiente na região de Mucugê, Chapada Diamantina - BA

Tourism is getting more and more importance in economic world, conquering new territories. Where there is substance economy with little occupational density. This process presents several local changes. The paper aims to analyze Chapada Diamantina region with its central point in Mucugê – BA. At beginning, the study has focused bibliographical review of works about tourism and their relation with the place. After that, geological characteristic and historical settlement of the place were analyzed. Then, fieldworks have done to data base, to survey impacts caused by the touristic process as well as interpretation of the relation occurred between tourism and landscape. At the end, the outcomes obtained from data analyzed became report, which presents proposal to improve the relation between tourism and the place.

Efeito da matriz na capacidade de aves flrestais moverem-se na paisagem

Matrix can be defined as a portion of the landscape, that somewhere in time suffered intense human disturbance, such as decreasing of native vegetation. The matrix surrounding the forest fragments may create a certain resistance to the movements of individuals (RICKETTS, 2001). The Atlantic rainforest present in the Corumbataí river basin lost about 89% of its original vegetation, leading to a highly fragmented landscape (VALENTE e VETTORAZZI, 2005). In this context, this study aimed to evaluate the effect of the matrix and the characteristic capacity of two forest birds, Dysithamnus mentalis and Basileuterus flaveolus, moving around the landscape. With this aim, six fragments were selected, three with sugar cane matrix, three with Eucalyptus sp. matrix. The methodology utilized to evaluate the response of the birds was playback technique. First the vocalizations were carried out at the forest matrix boundary, in the edge, attracting individuals to the matrix. As the responses were generated, the playback was moved increasingly inside the matrix, observing the distances traveled by the species. The control trials were conducted inside the fragments, the playback was played at the edge and as the responses were observed, the vocalizations were carried out inside the fragment until the moment that individuals ceased answers. It could be observed that for individuals of D. mentalis the matrix generated a high resistance, because no individual entered the matrix. For B. flaveolus the average distance traveled in both matrices was 70 meters, indicating statistically high resistance of the sugar cane matrix and Eucalyptus sp. Considering the characteristics of different matrices, it was found that both matrices generate similar resistance in the movement of these species

Análise do conforto térmico da cidade de Mirandópolis/SP em seus espaços abertos

Mirandópolis/SP appeared in 1934 from the railroad “the Brazil Northwest”, that there it served one of the points of its stretch that had as main function to drain the agricultural production northwestern native of São Paulo of that time. The installation of the town happened absent of concerns with initial urbanístico planning, thus modifying its natural landscape and modifying characteristic ambient without compensatory measures aiming at a future expansion of the urban mesh. Fact this that still causes today consequences the quality of life of the people and also the observed thermal comfort later. Ahead of this, the present work had for objective to identify through measurements of temperature and relative humidity of the city of Mirandópolis/SP the differences that in the fabric urban they corroborate for a comfort situation or thermal discomfort to the outdoors in accordance with the Diagram Bioclimático de Olgyay the collection of data was made throughout the month of July of 2011 involving the attainment of information of Temperature and relative humidity of air and questionnaire applied to the passer-bys in the act of the measurements. Also approaching the different thermal dynamic of the zones of housing in relation to the Urban Cannyon that develops the commerce as predominant activity. This research sample that, although a city to be small, the quality of life of its inhabitants is not only guaranteed by the transport or that its thermal comfort reveals inside homogeneous of the urban perimeter, but that it has yes heterogeneidade in the scope of the urban climate in these spaces

Tsukamoto s Theorem in Characteristic two

In this paper it is proved that hermitian forms over quaternion division algebras over local fields of characteristic two are classified by their dimension and discriminant.

Using landscape metrics to analyze micro-scale soil erosion processes

Methods of recording soil erosion using photographs exist but they are not commonly considered in scientific studies. Digital images may hold an expressive amount of information that can be extracted quickly in different manners. The investigation of several metrics that were initially developed for landscape ecology analysis constitutes one method. In this study we applied a method of landscape metrics to quantify the spatial configuration of surface micro-topography and erosion-related features, in order to generate a possible complementary tool for environmental management. In a 3.7 m wide and 9.7 m long soil box used during a rainfall simulation study, digital images were systematically acquired in four instances: (a) when the soil was dry; (b) after a short duration rain for initial wetting; (c) after the first erosive rain; and (d) after the 2nd erosive rain. Thirteen locations were established in the box and digital photos were taken at these locations with the camera positioned at the same orthogonal distance from the soil surface under the same ambient light intensity. Digital photos were converted into bimodal images and seven landscape metrics were analyzed: percentage of land, number of patches, density of patches, largest patch index, edge density, shape index, and fractal dimension. Digital images were an appropriate tool because they can generate data very quickly. The landscape metrics were sensitive to changes in soil surface micro-morphology especially after the 1st erosive rain event, indicating significant erosional feature development between the initial wetting and first erosive rainfall. The method is considered suitable for spatial patterns of soil micro-topography evolution from rainfall events that bear similarity to landscape scale pattern evolution from eco-hydrological processes. Although much more study is needed for calibrating the landscape metrics at the micro-scale, this study is a step forward in demonstrating the advantages of the method.

Physical and mechanical characteristic of particleboards produced with residues of sugarcane and stem leaves of bamboo bonded with castor oil adhesive

In this research the aim was produce a particleboard with alternative materials and evaluated its physical and mechanical characteristics. The raw materials used are residues from sucarcane bagasse (SC) (Saccharum officinarum) and stem leaves of bamboo (B) (Dendrocalamus giganteus), bonded with a bi component adhesive based on castor oil. It was produced particleboards with five different traces: 100% SC, 75% SC+25% B, 50% SC+50% B, 25% SC +75%B and 100 % B. Their physical and mechanical characteristics were evaluated accordingly to Brazilian standard NBR 14810-3. Regarding the results obtained, it can be detached that for physical and mechanical evaluation it is evident a negative relation among the amount the sugarcane bagasse and their physical and mechanical characteristics, that is particleboards with low concentrations of sugarcane bagasse had better results. However all particleboards could be recommended for use as sealing particleboards in the segment of civil construction.
