Continuous partial trends and low-frequency oscillations of time series

International audienceThis paper presents a recent methodology developed for the analysis of the slow evolution of geophysical time series. The method is based on least-squares fitting of continuous line segments to the data, subject to flexible conditions, and is able to objectively locate the times of significant change in the series tendencies. The time distribution of these breakpoints may be an important set of parameters for the analysis of the long term evolution of some geophysical data, simplifying the intercomparison between datasets and offering a new way for the analysis of time varying spatially distributed data. Several application examples, using data that is important in the context of global warming studies, are presented and briefly discussed

SGI como instrumento complementar na avaliação do impacto ambiental da agricultura.

Divulga a metodologia, desenvolvida pelo Núcleo, de caracterização e avaliação do impacto ambiental da agricultura, baseada no uso de SGI. O projeto foi executado sobre conjuntos de pequenas propriedades com diferentes sistemas de produção. Na escala municipal articulou espacialmente, via SGI, o uso das terras e os coeficientes técnicos dos sistemas de produção aferentes. Foram geradas 32 cartas de impacto ambiental da atividade agrícola, por recursos e insumos

Measures and model of the churches of São Miguel (Azores)

The religious spaces are carriers of great symbolic importance, standing out in the urban fabric not only for their location, but also for their scale in relation to the surrounding buildings. We show the relevance of the religious space in the São Miguel island (Azores) urban fabric, where the church presents itself as an element of great importance. It is the generator of the urban fabric, and it is usually strategically located as a landmark of the civic centre of the localities. This study presents an analysis of the main façades of the parish churches of the island of S. Miguel built during the eighteenth and nineteenth centuries. It highlights the existence of a typology of façade, which is a consequence of the materials and building systems existing there at the time. This demonstration continues the studies carried out by Sousa (1986) with the concept of façade “micaelense baroque ornamentation” and Caldas (2012) with the concept of “micaelense baroque façade” and “micaelense type façade”. Methodologically, the investigation was carried out through the analysis of the elements that make up the façades of the parish churches, the study of old and current photography, and drawings made in CAD; and the systematization of façades by grouping them into categories and establishing a typology between the various churches of the eighteenth and nineteenth centuries.info:eu-repo/semantics/publishedVersio

Importância do parque estadual Fritz Plaumann na qualidade da água do lajeado Cruzeiro, Concórdia, SC.

A legislação ambiental brasileira busca minimizar os impactos negativos ou prejudiciais nas UCs pela presença de zonas de amortecimento no entorno destas. A área de estudo em questão compreende o Lajeado Cruzeiro, localizado no entorno do Parque Estadual Fritz Plau-mann, Concórdia, SC, que faz parte de uma região de elevada capacidade rural produtiva e, portanto, sensível a problemas de poluição ambiental decorrentes da atividade animal. O presente trabalho apresenta os dados de monitoramento de alguns parâmetros meteorológicos, físico-químicos e microbiológicos do lajeado Cruzeiro, e a indexação de seus valores, na forma do Índice de Qualidade de Água (IQA) para contextualização da qualidade hídrica e ambiental desta região. Essa ferramenta possibilita a observação do efeito da depuração natural do próprio curso d?água, garantida pela presença da unidade de conservação na região, resultando na melhoria do padrão de qualidade da água quando da proximidade da foz do lajeado. Brazilian environmental legislation seeks to minimize the negative or harmful impacts in protected areas by the presence of buffer zones in their surroundings. The study area comprises the Cruzeiro stream, located in the vicinity of the State Park Fritz Plaumann, Concordia, SC, which is part of a rural region of high productive capacity and thus sensitive to problems of environmental pollution resulting from farm animal activity. This paper presents the monitoring data of some meteorological, physico-chemical and microbiological parameters of Cruzeiro stream, and the indexation of their values in the Water Quality Index (WQI) to contextualize the water and environmental quality of the region. This tool allows the observation of the effect of natural purification of the watercourse itself, guaranteed by the presence of the protected area in the region, resulting in improved water quality standard when approaching the mouth of the stream
