13. Ecodinâmica coastal dunes of Sergipe / Ecodinâmica das dunas costeiras de Sergipe
The ecodynamics analysis of coastal dunes of Sergipe determined the role and the interactive effect of the anthropic action and of the natural dynamics in the occured fast ambient changes in two sample units of the Northern and Southern Coastline from Sergipe. The present research searched the detailing of the existing ambient dynamics in the fields of the d

14. PREPARO DO SOLO E CRESCIMENTO DE Eucalyptus grandis Hill ex Maiden. EM ARGISSOLO / SOIL TILLAGE AND INITIAL GROWTH TO Eucalyptus grandis Hill ex Maiden. IN HAPLUDALF SOIL
The Eucalyptus plantation is growing fast in south Brazil due its easy clime adaptation and diverse use of its wood. The ecosystems where the expansion is going on are fragile to anthropic action implying in a need of careful planning to set forest projects. One of important steps is the soil tillage used to implant forests which may have as main concern cre

15. Aplicação de resíduo URA na remediação química de solos contaminados por Cd, Pb e Zn. / Application of residue URA in the chemical remediation of soil contaminated by Cd, Pb and Zn.
The objective of this study was to evaluate the alteration in the solubility of heavy metals in soils contaminated by anthropic action, applying an iron oxide residue (CSN) that acted from the chemical containment, aiming to recover contaminated areas and representing a low cost alternative in the containment of heavy metals. An experiment was conducted in t

18. Evolution tecnogenic systems of the Mucicipality of São Paulo / Evolução dos sistemas tecnogênicos no Município de São Paulo
O papel do ser humano como agente eeológico tem sido amplamente considerado como modificador da superfície da Terra através de feições e depósitos denominados tecnogênicos. Na presente dissertação de mestrado apresenta-se nova forma de abordagem na qual os processos tecnogênicos são analisados na forma de sistemas, ou seja, sistemas tecnogênicos,

19. Variabilidade espacial e temporal da qualidade das Ãguas no trecho perenizado na Bacia HidrogrÃfica do Curu, Cearà / Spatial and temporal variability in quality of the water in the perennialized stretch of the hydraulic basin of river Curu, Ceara state, Brasil
This research aims analyze the spatial and temporal variability in quality of the water used to perennialized area the hydraulic basin of river Curu, Ceara state, Brazil, evaluating the effects of the anthropic action and the influence of the different types of soils in the region. The following parameters were appraised: cations (Ca2+, Mg2+, Na+, K+), anion

20. Isolamento e identificação de actinobacterias em solos de terra preta antropogenica (TPA) da Amazonia Central por ARDRA e sequenciamento do gene 16S rRNA. / Isolation and identification of actinobacteria in anthropogenic dark earth of Central Amazon by ARDRA and seguencing of 16S rRNA gene.
Actinomycetes have been especially useful in the pharmaceutical industry for their unlimited capacity to produce secondary metabolites with diverse chemical structures and biological activities. The search for novel species of actinomycetes constitutes an essential component for the discovery of new pharmaceutical drugs. Actinomycetes are widely distributed

21. Diversidade genética em populações de Aechmea fulgens Brongn. (Bromeliaceae) em fragmentos de Mata Atlântica em Pernambuco.
Habitats fragmentation is the greatest cause of biodiversity erosion in tropical forests among the anthropic action. Due to the high degree of fragmentation and the isolation of the remaining Atlantic forest, many populations are being extinguished locally while others are suffering losses of its genetic variability. The Bromeliaceae family has a great varie

22. Mechanical tillage of mining degraded areas at Jamari National Forest (Rondonia - BR) / Mecanização no preparo de solo em areas degradadas por mineração na Floresta Nacional do Jamari (Rondonia-BR)
The usage of a nation s natural resources directly implies the manipulation of natural environments on the terrestrial surface. In this scenario, estimates indicate that mining contributes to one percent of the degradation of the soils of the planet. It is observable that, although it seems to be a small number, this percentage denotes a high intensity of de

23. High resolution positioning â suitability and aplication to coastal morphology / Posicionamento de alta resoluÃÃo â adequaÃÃo e aplicaÃÃo à morfologia costeira
The coastal zone concentrates a large economic potential and due to its importance to the sustainable development it was subject of discussion during the United Nations Conference on the Environment, Rio 92. The Agenda 21, the basic document generated during this conference, includes a specific chapter (Chap. 17) that deals with the protection of the oceans

24. Riscos e gestÃo ambiental no estuÃrio do Rio malcozinhado, Cascavel-CE
The Rio Malcozinhado lagoon-estuarine system is located in the Cascavel municipality, in the Cearà State Southeastern littoral 75km away from Fortaleza, Northeastern Brazil. Its 380 km2 hydrographic basin lies on basement rocks, Plio- Pleistocene Barreiras Formation sediments and Quaternary deposits. The urban expansion of the area in the last two decades w
