1. Estrutura hierárquica na resposta das distribuições geográficas de plantas do Cerrado à mudanças climáticas / Hierarchical structure in the response of geographic distributions of Cerrado plants to climate change
The climate can be considered an extremely important factor in vegetation distribution and its characteristics in a global context. Climate changes affect the global distribution of vegetation in the distant past and probably will affect in the future. Spatial distribution models of species (SDMs), also known as niche models are one of the best current tools

2. Importance of appropriated sectorization to reduce real water loss in public supply system. / Importância da setorização adequada para combate às perdas reais de água de abastecimento público.
The following study aims to present the effect of pressure reducing in the distribution networks over the water real loss. For development of the studies, were collected field data that allowed to evaluate the distribution systems conditions and build mathematical models for hydraulic simulations. From the hydraulics models, were developed cases for the Wate

3. Uma contribuição à alocação de geração distribuída, a inserção de PCHs com máquinas síncronas nos sistemas rurais de média tensão
The present work is about an analysis in the domain of distributed generation (DG) allocation in rural distribution systems; the study takes into account the synchronous machines. In such a way, it was possible to research several impacts caused by DG in distribution systems, such as: the rotor angle stability problem under small disturbances; increase of vo

4. Automação como recurso de planejamento de redes de distribuição de energia elétrica. / Automation as resource for distribution systems planning.
Concerning the components of an electrical distribution network and their susceptibility to functional failures or need for maintenance actions, planning and project criteria should be adopted to assure continuity of energy supply even though some components may be out of work. Traditionally the power systems, especially in power transmission and distributio

5. Avaliação pré-clínica de lipossomas pH-sensíveis de longa circulação contendo cisplatina
cis-Diamminedichloroplatinum (II) or cisplatin (CDDP) is one of the anticancer agents most widely used in the treatment of solid tumors. However, the effectiveness of its clinical use is hampered by the induction of severe side effects and its tendency to provoke chemoresistance. To circumvent these inconveniences, drug delivery systems, such as long-circula

6. COMPARATIVE ANALYSIS BETWEEN THE MAXIMIZATION OF VOLTAGE STABILITY MARGIN AND LOSS REDUCTION IN DISTRIBUTION SYSTEMS / ANÁLISE COMPARATIVA ENTRE A MAXIMIZAÇÃO DA MARGEM DE POTÊNCIA E MINIMIZAÇÃO DAS PERDAS TÉCNICAS EM SISTEMAS DE DISTRIBUIÇÃO DE ENERGIA ELÉTRICA
The increase of the consumption of electric energy takes the distribution systems to operate next to its limits, which might cause situation of maximum active and reactive power flow in the branches, that is, problems of voltage stability. The change of the topology of the network allows to find a configuration where de voltage stability indexes are far from

7. Hybrid genetic algorithms for loss reduction in distribution systems under variable demand / Algoritmos geneticos hibridos para redução de perdas tecnicas em redes primarias de distribuição considerando variações de demandas
Esse trabalho propõe um Algoritmo Genético Híbrido para o problema de redução de perdas em redes de distribuição de energia elétrica através de reconfigurações da rede, considerando-se as variações das demandas ao longo do dia. É adotada uma formulação que evita reconfigurações freqüentes, procurando encontrar uma única configuração par

8. Modeling, development of software for designing, and evaluation of drip irrigation systems with microtubes. / Modelagem, desenvolvimento de software para dimensionamento, e avaliação de sistemas de irrigação por gotejamento com microtubos.
The use of microtubes has been increasing especially in poor countries of Asia and Africa, where international organizations struggle for the development of small farmers through the insertion of low cost technologies. Within this context and with the intention of offering technical and scientific background for the development of a low cost and high technol

9. Ecologia e genetica da mandioca na agricultura itinerante do litoral sul paulista : uma analise espacial e temporal
This study focuses the inter-relationships between the men, the farm environment, and the domesticated crop species, under the perspective of the evolutionary dynamics of cultivated plants. The main objective of this study was to evaluate the features related to the conservation, loss, and amplification of the varietal diversity of manioc (Manihot esculenta

10. Ammonia- and Nitrite-Oxidizing Bacterial Communities in a Pilot-Scale Chloraminated Drinking Water Distribution System
Nitrification in drinking water distribution systems is a common operational problem for many utilities that use chloramines for secondary disinfection. The diversity of ammonia-oxidizing bacteria (AOB) and nitrite-oxidizing bacteria (NOB) in the distribution systems of a pilot-scale chloraminated drinking water treatment system was characterized using termi

11. Loss of non-phosphorylated neurofilament immunoreactivity, with preservation of tyrosine hydroxylase, in surviving substantia nigra neurons in Parkinson's disease.
The distribution of neurofilament immunoreactivity in the substantia nigra was examined by immunohistochemistry in five patients dying with Parkinson's disease and six control patients dying without neurological disease. In controls, pigmented neurons in the substantia nigra were intensively labelled by SMI32, a monoclonal antibody to non-phosphorylated neur

12. Dual role for neural crest cells during outflow tract septation in the neural crest-deficient mutant Splotch2H
Splotch2H (Sp2H) is a well-recognized mouse model of neural crest cell (NCC) deficiency that develops a spectrum of cardiac outflow tract malformations including common arterial trunk, double outlet right ventricle, ventricular septal defects and pharyngeal arch artery patterning defects, as well as defects in other neural-crest derived organ systems. These
