A puxada de rede: cooperação, coletividade e ajuda mútua em imagens

Artisanal fishing is a practice developed throughout the Brazilian coast, within territories and cultural meanings. It is one of the main productive activities carried out by some traditional communities, among them, the jangadeiros on the coast of Northeast Brazil. Among the modalities of fishing practiced by them is the “pull fishing net”, a community practice that combines mutual help and cooperation in which fishermen gather to cast and pull the net, sharing the catch. Here, we demonstrate the configuration and cultural meanings involved in the “pull fishing net”. We also discuss the importance of photographic production in fieldwork with traditional communities for capturing the symbolic elements present in the traditional way of life. Thus, the use of photographs made it possible to make records that demonstrate elements of cooperation and collectivity present in this activity.A pesca artesanal é uma prática desenvolvida em todo o litoral brasileiro, envolvendo territórios e significados culturais, sendo uma das principais atividades produtivas realizada por algumas comunidades tradicionais, entre elas, os jangadeiros, no litoral do Nordeste brasileiro. Entre as modalidades de pesca praticadas por eles está a “puxada de rede” (pesca de tresmalho), uma prática comunitária que agrega ajuda mútua e cooperação em que pescadores se reúnem para lançar e puxar a rede, compartilhando os pescados. Aqui, pretende-se demonstrar a configuração e os significados culturais imbuídos na puxada de rede, bem como debater a importância da produção fotográfica nos trabalhos de campo com comunidades tradicionais para captar os elementos simbólicos presentes no modo de vida tradicional. Dessa forma, o uso de fotografias possibilitou fazer registros que demonstram elementos de cooperação e coletividade presentes nessa atividade

The Sunrise Mission

The first science flight of the balloon-borne \Sunrise telescope took place in June 2009 from ESRANGE (near Kiruna/Sweden) to Somerset Island in northern Canada. We describe the scientific aims and mission concept of the project and give an overview and a description of the various hardware components: the 1-m main telescope with its postfocus science instruments (the UV filter imager SuFI and the imaging vector magnetograph IMaX) and support instruments (image stabilizing and light distribution system ISLiD and correlating wavefront sensor CWS), the optomechanical support structure and the instrument mounting concept, the gondola structure and the power, pointing, and telemetry systems, and the general electronics architecture. We also explain the optimization of the structural and thermal design of the complete payload. The preparations for the science flight are described, including AIV and ground calibration of the instruments. The course of events during the science flight is outlined, up to the recovery activities. Finally, the in-flight performance of the instrumentation is briefly summarized.Comment: 35 pages, 17 figure

ORNAMENTAL PLANTS FROM THE COMMELINACEAE AND PIPERACEAE FAMILIES EXISTING IN THE GREENHOUSES OF THE BOTANICAL GARDEN "AL. BUIA" FROM CRAIOVA

Greenhouses of the Botanical Garden "Al. Buia" in Craiova house a varied collection of plants, belonging to numerous families. In this paper, species from the families Commelinaceae and Piperaceae are presented. The family Commelinaceae includes herbaceous plants, rarely lianas, native to tropical and temperate regions of the world, except Europe. In the greenhouse, this family is represented by ornamental species of the Callisia, Cyanotis and Tradescantia genera. The family Piperaceae comprises herbaceous plants, subshrubs or lianas, rarely trees, with simple, entire leaves, with stipules, often succulent and with small, bisexual or unisexual flowers, grouped in spikes or spadix. They are plants that grow spontaneously in tropical or subtropical areas around the world, but the greatest diversity is found in the Americas in a wide range of habitats being distributed from the southern United States of America to Chile and Argentina. In the greenhouses of the Botanical Garden this family is represented by two genera: Piper and Peperomia. In addition to the decorative effect, numerous representatives of the Piperaceae family are used as a food ingredient (Piper longum, Piper nigrum, Peperomiapellucida) and in traditional medicine to treat a wide variety of conditions: inflammatory diseases, gastrointestinal and respiratory tract disorders, acne, kidney diseases. Therefore, disseminating information about the existing ornamental plants in the greenhouses of the Botanic Gardens on the one hand supports their botanical value and on the other hand represents another step for environmental education
