25. Aldeando sentidos: os Xucuru-Kariri e o serviço de proteção aos índios no agreste alagoano. / Aldehyde directions: Xucuru-Kariri and service protection to Indians in Alagoas harsh.
This dissertation is a study of the process of indigenous village in the Northeast through Indigenous Posts when the indigenous policy was under the remit of the Protection of Indians Office. In this case, the village of Xucuru - Kariri at the Canto Farm, with the installation of the post Irineu dos Santos. It will be used documentation of the indigenous org

26. Mapeamento de geounidades do meio físico e biótico em área da Antártica Marítima / Mapping geounits of the physical and biotic environment in area of Maritime Antarctica
The objective of this work was to carry out a detailed survey of the physical and biotic environment of the area between the Ecology Glacier and the Italy Valley, part of the Antarctic Specially Managed Area of Admiralty Bay, King George Island, Maritime Antarctica, at cartographic scale suitable for assisting studies of environmental monitoring. The non-con

27. Avaliação da geometria do produto Ikonos Geo / Geometric evaluation of Ikonos Geo product
Geometric correction of satellite images is relevant to cartographic applications and to integrate these images in geographic information systems. Image correction consists in the distortion elimination, caused by the sensor and by the observed object, through models of image geometry and ancillary information such as digital terrain model and control points

28. Somaclonal variation in Asparagus officinalis plants regenerated by organogenesis from long-term callus cultures
Somaclonal variation in plants regenerated by organogenesis from long-term cultured calluses of two diploid staminate genotypes of Asparagus officinalis cv. Argenteuil was characterized by plant phenotype, ploidy, meiotic behavior, pollen viability, fruit and seed set, and AFLP profiles. Phenotypic deviations from the donors were detected in foliage color, f

29. Revisiting the first-principles approach to the granular gas steady state
We extend a Fokker-Planck formalism, previously used to describe the behavior of a cooling granular gas, with a Hertzian contact potential and viscoelastic radial friction, giving a velocity dependent coefficient of restitution. In the present work, we study the more general case of a steady-state with finite kinetic energy, far from equilibrium, due to the

30. Merleau-Ponty e o projeto de restituição da experiência primordial da natureza
The present dissertation looks upon tbe project of restitution of Nature s primordial experience through the eyes of Maurice Merleau-Ponty. In this perspective, an attempt to envisage - beyond the classical tbougbt - a new sense for the concept of "Nature" is tried, due to the fact that Nature presents itself today as an exemplar manifestation and therefore,

31. Modelagem fenomenologica e simulação bidimensional da fluidodinamica de reatores de leito fluidizado circulante
Circulating Fluidized Bed (CFB) reactors are used in a variety of industrial applications especially related to combustion and catalytic cracking. The fluid dynamic prediction of CFB is fundamental in its development and optimisation. In this work, a computer code for the simulation of the fluid dynamics of Circulating Fluidized Bed Reactors was developed. T

32. Comportamento mecanico de laranja-pera (Citrus Sinensis Osbeck)
Biological materiaIs exhibit elastic and viscoelastic properties. The knowledge of these properties is important for the design and development of equipment applied in the harvesting, processing, transportation, conditioning and selection of fruits. This work made possible the development of a device capable of measuring espherical bodies mechanical properti

33. Metodologia de sensoriamento remoto no monitoramento de modificações no canal fluvial e atualização de cartas náuticas / Methodology of remote sensing for monitoring modifications in the fluvial channel and updating nautical charts
This work has the finality to propose methodology of Remote Sensing for monitoring the fluvial morphology of a section s Solimões river (Brazil), as support for artographic updating of nautical charts. In developing of the methodology, the following material was used: LANDSAT MSS and TM images, aerial photographs, cartographic documents (bathymetric and top

34. Preventing ventricular fibrillation by flattening cardiac restitution
Ventricular fibrillation is the leading cause of sudden cardiac death. In fibrillation, fragmented electrical waves meander erratically through the heart muscle, creating disordered and ineffective contraction. Theoretical and computer studies, as well as recent experimental evidence, have suggested that fibrillation is created and sustained by the property

35. The role of Na(+)-Ca2+ exchange current in electrical restitution in ferret ventricular cells.
1. The mechanisms underlying electrical restitution (recovery of action potential duration after a preceding beat) were investigated in ferret ventricular cells. The time to 80% recovery (t80) of action potential duration was approximately 204 ms. 2. At a holding potential of -80 mV, the Ca2+ current (ICa) reactivated and the delayed rectifier K+ current (IK

36. Electrical restitution in the endocardium of the intact human right ventricle.
OBJECTIVE--To characterise electrical restitution in the intact human heart. PATIENTS AND METHODS--A series of monophasic action potential electrical restitution curves were constructed from a single right ventricular endocardial site in eight patients (three men) without structural heart disease aged 52-68 (mean 55 years). A combination pacing/monophasic ac
