1. Potential risk of drift from inclined fan nozzles
RESUMO O controle de pragas, doenças e plantas daninhas nas culturas de larga escala dependem da aplicação de produtos fitossanitários. Estas aplicações estão sujeitas a diversos fatores que podem levar à deriva. O objetivo deste trabalho foi avaliar a deriva de pontas de pulverização de jato plano inclinado. A deriva foi coletada em túnel de vent

2. STEADY STATE AND PSEUDO-TRANSIENT ELECTRIC POTENTIAL USING THE POISSONBOLTZMANN EQUATION
A method for analysis of the electric potential profile in saline solutions was developed for systems with one or two infinite flat plates. A modified Poisson-Boltzmann equation, taking into account nonelectrostatic interactions between ions and surfaces, was used. To solve the stated problem in the steady-state approach the finite-difference method was used

3. Processos dinÃmicos e evolutivos da zona costeira de Itamaracà por sensoriamento remoto e medidas in situ
The coastal zone of Itamaracà is like a highly dynamic environment where land and oceanic processes interact altering frequently coastal characteristics. In this context, this current study examines the responsible processes of such changes from the development and application of methodologies, which includes digital image processing and the obtaining of in

4. Consumo de sal entre sujeitos portadores de hipertensão arterial : estudos dos determinantes individuais do comportamento / Salt consumption among hypertensive subjects : study of behavioral individual determinants
The aim of this study was to identify the individual factors associated to the behavior of low salt consumption among hypertensive subjects, based on an extension of the Theory of Planned Behavior (TPB). The salt consumption was evaluated by 3 distinct behaviors: Behavior I - the use of less than 4g of salt (corresponding to 1 "flat" teaspoon of salt) when y

5. Avaliação de embalagens flexiveis esterilizaveis e alimentos de pronto consumo para equipagens de aeronaves e para uso terrestre. / Evaluation of retortable pouch and foods of ready consumption for equipages of aircraft and terrestrial use.
The operational meals means are fundamental to the implementation of the activities of training and actual deployment of the armed forces around the world and is still employed in circumstances of contingency of civil order. In this sense, the Brazilian Air Force, in the search for solutions and continuing improvements in the area of the food supply, is prio

6. Characterization of the salt flat (apicum) associated with a mangrove forest in Guaratiba, Sepetiba Bay, Rio de Janeiro - Brazil / Caracterização da planície hipersalina ( Apicum ) associada a um bosque de mangue em Guaratiba, Baía de Sepetiba, Rio de Janeiro - RJ
Planícies hipersalinas são conhecidas em várias partes do mundo, por vezes intimamente associadas a manguezais. No Brasil são registradas do Pará a Santa Catarina, descontinuamente, por todo o litoral. Representam reservatórios de nutrientes e zonas de retração de bosques de mangue, no caso de elevação do nível médio do mar, merecendo maior aten�

7. Binding the Mammalian High Mobility Group Protein AT-hook 2 to AT-Rich Deoxyoligonucleotides: Enthalpy-Entropy Compensation
HMGA2 is a DNA minor-groove binding protein. We previously demonstrated that HMGA2 binds to AT-rich DNA with very high binding affinity where the binding of HMGA2 to poly(dA-dT)2 is enthalpy-driven and to poly(dA)poly(dT) is entropy-driven. This is a typical example of enthalpy-entropy compensation. To further study enthalpy-entropy compensation of HMGA2, we

8. A rapid colorimetric assay for evaluating Legionella pneumophila growth in macrophages in vitro.
A rapid colorimetric technique for in vitro quantitation of Legionella pneumophila intracellular proliferation in macrophages is described. The assay is based on the electron transport activity of metabolically active L. pneumophila. The yellow tetrazolium salt 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) is cleaved by the mitochondrial

9. Scanning force microscopy of circular and linear plasmid DNA spread on mica with a quaternary ammonium salt.
Scanning force microscopy (SFM) offers the potential for subnanometer resolution in the investigation of nucleic acids, proteins, and their complexes. SFM is not bound by the requirement of classical transmission electron microscopy (TEM) for contrast enhancement through shadow casting or negative staining. A primary challenge, however, has been the reproduc

10. Kinetics of Escherichia coli destruction by microwave irradiation.
The kinetics of destruction of Escherichia coli cells suspended in a solution by microwave irradiation with a microwave oven were studied. During radiation at several powers, the temperature of 0.01 M phosphate buffer (PB), pH 7.0, in a glass beaker increased linearly at a rate of A (degrees Centigrade per second) according to the exposure time. When E. coli

11. The structure of the human βII-tryptase tetramer: Fo(u)r better or worse
Tryptases, the predominant serine proteinases of human mast cells, have recently been implicated as mediators in the pathogenesis of allergic and inflammatory conditions, most notably asthma. Their distinguishing features, their activity as a heparin-stabilized tetramer and resistance to most proteinaceous inhibitors, are perfectly explained by the 3-�

12. Modeling Membrane Deformations and Lipid Demixing upon Protein-Membrane Interaction: The BAR Dimer Adsorption
We use a self-consistent mean-field theory, designed to investigate membrane reshaping and lipid demixing upon interaction with proteins, to explore BAR domains interacting with large patches of lipid membranes of heterogeneous compositions. The computational model includes contributions to the system free energy from electrostatic interactions and elastic e
