We are reporting a new simple optical element to generate halos. We have observed interesting patterns of light scattering in Plateau borders in foams. In analogy to the atmospheric phenomena known as parhelic circle, sun dogs, and sun pillars, we have named the features of the patterns observed as parlaseric circle, laser dogs, and laser pillars. The triangular symmetry of the Plateau borders is analogous to the hexagonal symmetry of ice crystals which produce these atmospheric phenomena. Working ...

We have studied some aspects of the optics of the light scattering in foams. This paper describes the difference between rays and diffracted rays from the point of view of geometrical theory of diffraction. We have represented some bifurcations of light rays using dynamical systems. Based on our observations of foams, we created a solid optical device. The interference patterns of light scattering in foams forming Airy fringes were explored observing the pattern named as the eye of Horus. In the ...

The purpose of this study was to propose a conceptual framework for understanding how to establish athletes as brands. Based on an extensive literature review, the proposed model includes the antecedents of athlete brand, its measurement dimensions and implications. Five antecedents are included in the model: media, oral communications, impression management, social agents, and teams and sport. The components of athlete brand consist of on-field attributes and off-field attributes. In turn, the ...

In this study, six highly polymorphic microsatellite loci and a categorical paternity analysis approach were used to investigate the contemporary pollen gene flow in the neotropical tree species Symphonia globulifera. Data for this study were taken from a 500 ha experimental plot in a dense terra firme forest in the Eastern Brazilian Amazon and included the mapping and genotyping of 161 reproductive trees, representing more than 90% of all adult trees, and the collection of 748 open-pollinated seeds ...

Essa recuperação consiste em perceber os trabalhos de Comte em sua inteireza e a partir de sua lógica interna, enfatizando em particular a sua segunda grande obra, o Système de politique positive (1851-1854), e as suas contribuições para a reflexão social e política contemporânea. A fim de tornar inteligível a novidade dessas novas pesquisas, apresentamos uma ...

The objective is to minimize the global cost including area cost and pumping cost or just area minimization, depending on data availability, rigorously following the standards of the Tubular Exchanger Manufacturers Association and respecting pressure drops and fouling limits. Given fluids temperatures, flow rates, physical properties (density, heat capacity, ...

The effects of Ag addition on some physical properties of YBa2Cu3O7-δ superconductor has been studied. The samples were produced by different routes and characterized by scanning electron microscopy, differential thermal analysis, thermogravimetric analysis, X-ray diffraction and nanoindentation. The superconducting properties were studied by dc magnetization and electrical resistivity measurements. The X-ray patterns revealed that all samples were polycrystalline and corresponded to the orthorhombic ...

In two-phase finite volume systems of electroneutral phospholipids, the electrolyte concentration is different in the two phases. The partitioning is highly anion-specific, a phenomenon not accounted for by classical electrolyte theories. It is explained if ionic dispersion forces that lead to specific ion binding are taken into account. The mechanism provides a contribution to active ion pumps not previously considered.

A previously healthy 24 year old athletic man became ill suddenly with pneumonia the day after swimming in the sea. Despite intensive support measures in the intensive care unit he died three hours after admission and 21 hours after his first symptom. Necropsy showed bilateral haemorrhagic necrotising pneumonia. Aeromonas hydrophila was isolated from a blood culture taken at admission and from the lungs at necropsy. The infection may have come from contaminated sea water.

Particle swarm optimization is employed here to evaluate the parametric regions where different dynamic phenomena (periodic oscillations, double-period oscillations, chaos) can be expected in dynamic models. The proposed algorithm comprises two fundamental steps: the rough evaluation of regions where the desired solutions can be found and solution refining. The refining step allows the search for unstable solutions that may coexist with the other stable attractors. No preliminary bifurcation analysis ...

The kinetics of zinc extraction and stripping have been investigated for the ZnSO4/D2EHPA/diluent system (D2EHPA=di(2-ethylhexyl) phosphoric acid), which is under consideration as a proposed reactive extraction liquid–liquid test system by the European Federation of Chemical Engineering. Data in low and high concentration domains have been fitted to chemical kinetic and kinetic–diffusive models in order to discern the mechanism of zinc extraction and stripping for practical operational conditions. ...

The transverse Kerr effect corresponds to a change of p-light reflectivity of a ferromagnetic surface without the change of polarisation when magnetisation is reversed. A phase change occurs that can also be measured. The phenomenological analysis is followed by the description of the set-up and by the first experimental results before discussion and conclusion.

An equilibrium model is proposed for the reactive system ZnSO4/di-2-ethylhexyl phosphoric acid (D2EHPA)/diluent being considered by the European Federation of Chemical Engineering as a test system, valid over a wide concentration range of extraction and stripping conditions. The model is supported by the statistical analysis of estimated parameters. Two simple consecutive reactions are assumed to give two zinc complexes with relative proportions changing as conditions change from extraction to stripping. ...

The bifurcation behavior of continuous free-radical solution loop polymerization reactors is analyzed in this work. A mathematical model is developed in order to describe the impact of the recycling pump and other external reactor parts upon the process dynamics and stability. Stability analysis is performed using bifurcation theory and continuation methods. It is shown that under certain operational conditions as many as seven steady states are predicted for the loop polymerization reactor. Oscillatory ...

An improved genetic algorithm approach, based on a new ranking strategy, has been proposed to conduct multi-objective optimization of chemical engineering problems. New operators have been introduced to enhance the algorithm performance and reduce the computational effort. A Pareto-set filter operator has been implemented to avoid missing Pareto optimal points during the evolutionary process. A niche operator has been adopted to prevent genetic drift, and an elitism operator, to insure the propagation ...

We present experimental results for the ultrasound transmission spectra and standing wave patterns of a rectangular block of fused quartz. A comparison is made between our data and an approximation of the theoretical staircase function for three-dimensional isotropic elasticity. The main emphasis of our study is on the role of mode conversion in regular ray-splitting billiards. We present the fluctuation statistics and find that these are described by the Gaussian orthogonal ensemble of random matrix ...
