1. A SPECTRAL AGROMETEOROLOGICAL MODEL FOR ESTIMATING SOYBEAN GRAIN PRODUCTIVITY IN MATO GROSSO, BRAZIL
ABSTRACT This study used spectral data integrated with the agrometeorological model by Doorenbos and Kassam to estimate soybean grain productivity in the state of Mato Grosso, Brazil. In the developed model, spectral data were used instead of meteorological data and biophysical parameters of the crop. For this purpose, the products of real and potential evap

2. Bioactivity and action mechanism of green propolis against Pythium aphanidermatum
Abstract: We have established how natural compounds from green propolis collected by the species Apis mellifera act against the growth of Pythium aphanidermatum. On the basis of mass spectrometry (Q-ToF MS), we determined that Artepillin C, the major constituent of green propolis, underlies the effect and displays activity against P. aphanidermatum at a mini

3. Lamina specific loss of inhibition may lead to distinct neuropathic manifestations: a computational modeling approach
Introduction It has been reported that inhibitory control at the superficial dorsal horn (SDH) can act in a regionally distinct manner, which suggests that regionally specific subpopulations of SDH inhibitory neurons may prevent one specific neuropathic condition. Methods In an attempt to address this issue, we provide an alternative approach by integrating

4. Caracterização bioquímica e biofísica da Celobiohidrolase II do fungo Trichoderma harzianum IOC3844 produzida por expressão homóloga / Biochemical and biophysical characterization of cellobiohydrolase II from Trichoderma harzianum IOC 3844 produced by homologous expression
The depletion of reserves, especially of refined oil , with increased energy demands and the urgent need to reduce the carbon emissions on the atmosphere, signals the necessity to search for new sources of energy renewable and clean. Concerns about global warming have led to an increased world interest in biofuels. The new concept of second generation biofue

5. Estudos biofísicos de chaperonas de secreção e de interações proteína-ligante / Biophysical studies on secretion chaperones and protein-ligand interactions
So far, the Xanthomonas axonopodis pv. citri (XAC) mechanisms of bacterial virulence is unknown. It is believed that secretion chaperones (CS) are involved in the XAC´s virulence process by first forming complexes with virulence factors, and assisting in their presentation to corresponding secretion systems using ATP as a source of energy. Fluorescence emis

6. Integrated experimental biophysics and molecular dynamics simulations of biomolecules in solution - the interaction of nuclear receptors with DNA response elements and the inter-domain dynamics of Cellobiohydrolase I / Estudos por modelagem e dinâmica molecular integradas a técnicas físicas para biomoléculas em solução - interação de receptores nucleares a elementos responsivos no DNA e dinâmica inter-domínios da celobiohidrolase I
Collective motions play a fundamental role in solution biomolecule dynamics and energetics. These movements can couple very distant regions in the protein structures affection, for instance, allosteric mechanisms, the establishment of macromolecular complexes, and on the integrated function of multidomain proteins as molecullar machines. In this thesis, we p

7. FormulaÃÃo MatemÃtica para CÃlculo de VariaÃÃo de ConcentraÃÃo em Escoamento EstacionÃrio / Mathematical Formulation For The Calculation Of Changes Of Concentration In Stationary Flow.
The main aim of this research is to evaluate a variation of concentration between the affluent and effluent in a biophysical or physicochemical system. The theoretical system of references used here was based upon a differential equation of steady flow, involving a chemical kinetics and a longitudinal dispersion, in which there is a number of sufficiently lo

8. Gestão de agregados minerais : análise e subsídios para políticas públicas / Management ggregates : comparite analysis betwen Canada and Brazil and subsidies for public policies
The biophysical and social disruption caused by aggregates mining has placed it at the center of conflict scenarios, either because of advancing urbanization on the aggregates resources or because of pressures from civil society to impose restrictions on their development. The search for solutions to this problem has required of the governments a large abili

9. Programa de computador para simulação de modelos de neurônios: aplicação à célula mitral do bulbo olfatório / Computer program for neuron models simulation: application to the olfactory bulb mitral cell
O presente trabalho descreve um programa de computador em linguagem Java que reproduz o modelo compartimental reduzido de célula mitral do bulbo olfativo construído por Davison, Feng e Brown (Brain Res. Bull. 51:393-399,2000), como uma simplificação do modelo detalhado de Bhalla e Bower (J. Neurophysiol., 69:1948-1965, 1993). O modelo reduzido considera

10. A spatially distributed hydroeconomic model to assess the effects of drought on land use, farm profits, and agricultural employment.
In this paper a high-resolution linked hydroeconomic model is demonstrated for drought conditions in a Brazilian river basin. The economic model of agriculture includes 13 decision variables that can be optimized to maximize farmers' yearly net revenues. The economic model uses a multi-input multioutput nonlinear constant elasticity of substitution (CES) pro

12. Structural characterization from empirical modeling and GRART model evaluation in the Eucalyptus spp. canopies spectral characterization / Caracterização estrutural a partir de modelos empíricos e avaliação do modelo GRART na caracterização espectral de dosséis de Eucalyptus spp
Empirical modeling and models based on transfer theory have been applied to estimate quantitative information from spectral data and from their relationships with canopy biophysical parameters. Both modeling strategies have been explored here in order to estimate structural and spectral information from extit{Eucalyptus} spp. (eucalipto) canopies. Correlati
