13. Impacto das Áreas de Preservação Permanente sobre a erosão hídrica na bacia hidrográfica do Rio da Prata, Castelo-ES / Impact of Permanent Preservation Areas on water erosion in the watershed of River Silver, Castelo-ES
A watershed is the primary unit of water resource management, because their behavior affects the hydrological occurrence and magnitude of water erosion. Hydrologic simulation models, which allow to estimate the hydrology and water erosion, consisting of important management tool to minimize environmental degradation in these units. The Permanent Preservation

14. Avaliação ecofisiológica de subamostras de alho cv. Amarante / Ecophysiological evaluation of cv. Amarante garlic subsamples.
Garlic cultivars present different yield potentialities, expressed by the plant s morphological and physiological characteristics, according to the environment and cultural management. Thus, twenty sub-samples of garlic cv. Amarante belonging to the Germplasm Bank of the Universidade Federal de Viçosa (BGH/UFV) were evaluated for their morphological and phy

15. DESENVOLVIMENTO INICIAL DE UM PLANTIO MISTO DE Eucalyptus urograndis E Acacia mearnsii EM SISTEMA AGROSSILVICULTURAL / INITIAL GROWTH AND PRODUCTIVITY IM MONOSPECIFIC AND MIXED STANDS OF Eucalyptus urograndis AND Acacia mearnsii IN AN AGROFORESTRY SYSTEM
Understanding the initial development in consortiated systems are vital to decide about practices to obtain a sustainable productivity, in relation to environmental resources in an agrossilvicultural site. Due to this, this study had as objective: - to evaluate the agricultural productivity in agroforestry systems with different arrangements of the forest sp

16. The invention of the flying saucers : Cold War, press and science in Brazil (1947-1958) / A invenção dos discos voadores : Guerra Fria, imprensa e ciencia no Brasil (1947-1958)
This work analyses the history of the ideas related to the flying saucers, an expression used during the 1940s and 1950s to mean aerial unidentified phenomena and objects. Alongside the text, we follow the changes suffered by this concept and its crystallization into a complex symbolic system related to the extraterrestrial visitors idea. We also observe the

17. Esteróides gonadais e metabolismo lipídico ao longo do ciclo reprodutivo de Arapaima gigas (SCHINZ, 1822) em ambiente natural / Gonad steroids and lipid metabolism along the reproductive cycle of Arapaima gigas (SCHINZ, 1822) in natural environmet
The aim of the present study was to investigate the possible physiological alterations related with reproduction in males and females of Arapaima gigas (pirarucu) in their natural environment. Pirarucu is an obligatory aerial respiration species belonging to a very ancient group of teleosts and inhabits Amazonian river. The main goals of this study were to d

19. In vitro propagation of tannia (Xanthosoma sagittifolium (L.) Schott) accessions / Propagação in vitro de germoplasma de taioba (Xanthosoma sagittifolium (L.) Schott)
With the objective to establish the in vitro propagation and to evaluate the behavior of tannia varieties, it was applied growth regulators concentrations and cultivation ways of propagation. They were evaluated the number of shoots (NB), length of the aerial part (CPA), length of the longest root (CR), weight of the total fresh matter (MF) and total drought

22. Morfologia e sedimentologia das praias do litoral sul do municÃpio de Olinda - PE
The littoral of Olinda has spaces with coastal erosion since the last century. Trying to soften the erosion and stabilize the shoreline, a good range of engineering techniques were used in the last 88 years. During the 60s decade were made two breakwaters semi submerged in front of the Carmo beach and 38 groins along the 1,8 km of the Bairro Novo beach. The

23. Cruzetas de polímeros reciclados: caracterização dos materiais, análise numérica e ensaios de modelos reduzidos / Recycled polymer crossarms: characterization of the materials, numerical analysis and tests in reduced models
Nowadays, wood is still the most used material in crossarms of aerial power distribution lines in Brazil. However, it has caused problems to power utilities concerning (i) degradation due to defects and attacks of fungi and insects, (II) higher operational costs to replace damaged pieces and (III) environmental problems, as the raw material has become scarce
