Teodora e Porcina: faces simbólicas da natureza em narrativas de mulheres sábias

This research looks at the collective imagination in which it keeps alive the issue of heroin wise. Two wise women appear in the narratives of popular history and the History of Donzela Theodora and History Imperatriz Porcina, collated by Luís da Câmara Cascudo in his Five Books of the People. The universality, mobility and circularity of these narratives are discussed by authors such as Bakhtin and Guinzburg. The research is developed from three key categories: Knowledge Magic as the knowledge of tradition (Almeida), sensitive knowledge (Levi-Strauss), thought mythical / magical / symbolic (Morin); Wise Women as carriers of this knowledge, which merge and overlap with the imagery of witches and healers; and Mythical Elements which corresponds to the archetypal images (Jung and Silveira), symbols and other images that relate to the magic universe, the magical beliefs and practices considered, ie belonging to the imaginary magic (Bethencourt). Porcina and Theodora are understood as bearers of knowledge of Métis (Detienne and Vernant), or the cunning intelligence, the manipulation of phármakon (Derrida), the healing potion, which may be the word or ointment of the herb. The route takes us to meet the great archetype of the Wise Woman as psychic power of the feminine, the anima. Narratives are medicinal balms (Estes) and is the clash between the anima and its embodiments by wise women, and animus, his opponents, which gives the transmutation of the psyche, a work comparable to that of alchemyThe Knowledge Magic, operating through the female, myth and nature can recover from its essential value to the emerging paradigm that suggests a more complete human science and a more plural

Análise dos fatores responsáveis pela alta salinidade do aqüífero fissural da microbacia da Riacho do Feijão - Pedro Avelino/RN

The fissures aquifer northeast semi-arid Brazilian, present high text frequently of leave, with of low a hídric availability. The research has as objective main to analyze the components that inside influence in the salinity of the waterbearing fissures of an evaluation physicist-chemistry of the water, leading in consideration the physical interventions of the environment. One used techniques of interpretation of image of Landsat satellite -1999 and delimitation of the micro basin through the topographical map SUDENE. One identified waters of the NaCl type with Ca++ and Mg++ in secondary concentrations. The analyzed wells (15), had presented an average salinity of 5.147 mg/L of STD and a well only supplies drinking waters with 319 mg/L of STD. The recharge of the aquifer one if carries through for infiltration in the open fracture of ortognaisse it migmatization. The type and directions of the fracture do not control the STD. Relations between salinity and out let do not exist. The quality of the well of low salinity is identical the superficial waters (aquifer dam and alluvial). The studies of the meteoric erosion processes had evidenced that in the transformations of the rock in ground, the Ca++ and Na+ are taken for superficial waters. The treatment of the data chemical showed that the grade of Na+, Ca++, Mg++ and Cl-are controlled for the evaporation process, from only water that would have the qualities of superficial waters or the well of low salinity. Already the HCO3-grade is controlled for the precipitation of the dolomite. The STD of this aquifer one would be consequence of the high tax of evaporation of dams constructed in regions of plain topography. You leave them precipitated in deep argillaceous ones dry dams are led for the aquifer in first rains. The research suggests some recommendations for the use and exploitation of the water salinity in piscicultura, carcinicultura, culture of the grass-salt (Atriplex sp), among others

efeito da aplicação de uma solução salina no crescimento e na composição química da atriplex nummularia

This study aimed to analyze the effect of a saline solution on growth and chemical composition of Atriplex nummularia, shrubby plant, absorbing salts used in the diet of animals and the management of water and saline soils. These plant seedlings were planted and grown in a reserved area at the Federal University of Rio Grande do Norte. The plantation was divided into two blocks, in which one of them was irrigated with saline solution with a concentration of 2840 mgL-1 of NaCl and the second group was irrigated with drinking water. After six months, the plants were collected, harvested and divided into three parts: leaf, thin and thick stem. Monthly, dimension measurements were carried out for cataloging the growth of Atriplex. Ion Chromatography (IC) and Optical Emission Spectroscopy Inductively Coupled Plasma (ICP-OES) were used to analyze the chemical composition of the partition plant parts. The results of these analyses revealed that an absorption process of anions and cations by Atriplex nummularia plant during its growth was achieved, in particular by a higher concentration of sodium and chloride ions. Scanning electron microscopy images showed and confirmed the presence of small crystals on the leaf surface. Electrical conductivity and pH measurements of the aerial parts of the plant were carried out and these results showed that the leaf is the plant part where there is a largest concentration of ions. In addition, measurements of specific surface were obtained from irrigated plants with saline solution, achieving higher surface area, in all cases. Plant dimensions obtained monthly showed that the plants irrigated with water grew 5% more than those plants irrigated with saline solution. Based on results obtained, Atriplex plant showed a higher potential to survive and adapt to environments (aquatic or geological) with high levels of salinity and this property can be used as a tool for removing salts/metals from industrial contaminated soils and effluents.
