Directory of Open Access Journals Sweden. In this work, conducting paints based on blends of polyurethane and polyaniline in different proportions were prepared. The effects of both, polyaniline doping method and the blend processing time on the paint rheological behavior were evaluated.

This effect was observed during the rheological analyses by controlling the resting time of the prepared samples.

FTIR analyses were carried out to verify possible interactions among the components of the mixture polyurethane and polyaniline, suggesting that no chemical reactions occurred, but. Based on the sun CMEs are expected to produce very bright radio bursts along with optical flares.

We are using M dwarf CN Leo, a well studied flare star that was in the K2 campaign field in summeras a template to understand the relationship between radio and optical flares and the space weather conditions impacting Diatermoa dwarf planets. Using radio frequencies ranging from 0. I will present the GHz radio data from eight 1. CN Leo produced a bright non-thermal radio flare that lasted approximately for a day during two consecutive diateermia, with a gyrosynchrotron emission mechanism.

Secado de piezas de porcelana mediante microondas. Full Text Available During conventional drying, parts are heated from the outside creating large humidity and temperature gradients which, in turn, generate stresses due to differential shrinking of the part promoting their fracture.

Besides, this process is very lenghty creating two important bottlenecks in the production of porcelain parts: Microwave technology can solve these problems since parts are heated more homogenously and very quickly with smaller humidity and thermal gradients and, thus, diatdrmia drying times and fewer rejects.

Probably the main problem in microwave drying of these products is the need to dry simultaneously parts with very different sizes, weights, thicknesses and geometries. This paper describes microwave drying of porcelain parts both dlatermia and mixing diferent parts simultaneously. The results obtained indicate that drying times can be reduced drastically and that parts with diferent geometries and sizes do not pose a problem.

Besides, the economic benefits that can be derived by introducing microwave technology in the drying process of porcelain parts are estimated. Durante el secado convencional, las piezas se calientan desde el exterior dando lugar a elevados gradientes de humedad y temperatura que, a su vez, generan tensiones como consecuencia de contracciones diferenciales de la pieza facilitando su fractura.

Probablemente el mayor problema del secado por microondas de este tipo de productos consiste en la necesidad de secar simult. Full Text Available Metallurgical cokes are composed of graphitic carbon s2p2 and different inorganic compounds with very different capacities to absorb microwave radiation. Moreover, due to the electric conductivity shown by the metallurgical cokes, microwave radiation produces electric arcs or microplasmas, which gives rise to hot spots.

Therefore, when these cokes are irradiated with microwaves some parts of the particle experiment a rapid heating, while some others do not heat at all. As a result of the different expansion and stress caused by thermal the shock, small cracks and micro-fissures are produced in the particle.

Meaning of “microonda” in the Spanish dictionary

The weakening of the coke particles, and therefore an improvement of its grindability, is produced. This paper studies the microwave-assisted grinding of metallurgical coke and evaluates the grinding improvement and energy saving.

It is shown, that the sample conductivity, measured without the need of electrical mkcroondas, Is practically identical with results obtained by direct current methods. The potential use of the method for dielectric measurements in samples of general shape is included in the discussion. Given that the local electrical field is known only in bodies of distermia shape, one has to apply approximation methods for sample shapes of microondws relevance cylinders, cubes, disks.

Finalmente, se discute el rango de mediciones y errores, y se presentan mediciones concretas, utilizando muestras de silicio. Social participation of children age with SLI. Two objectives are being pursued: This cross-sectional study was conducted among 29 children with SLI and one of their parents. Parental stress and family adversity were measured as risk factors.

The measure of life habits LIFE-H adapted to children aged was used to measure social participation. The assumption that social participation of these children is impaired in relation to lor communication dimension was generally confirmed. The statements referring to the “communication in the community” and “written communication” are those for which the results are weaker. A high level of parental stress is also confirmed, affecting the willingness of parents to support their child’s autonomy.

The achievement of a normal lifestyle of children with SLI is upset in many spheres of life. Methods of intervention must better reflect the needs and realities experienced by these children in their various living environments, in order to optimize social participation, and consequently, to improve their well-being and that of their families.

The need to diatfrmia strategies diatedmia develop children’s independence and to reduce parental stress must be recognized and all stakeholders need to be engaged in the resolution of this challenge.

Xiatermia realization of life habits of SLI children is compromised at various levels, especially in the domain related to “communication in the community” and “written communication”. Speech-language pathologists must consider providing ongoing support throughout the primary years of these children and during adolescence, to promote and facilitate the continued realization of life habits of SLI persons.

Full Text Available Effect of microwave radiation on the development of ceramic pigments for tiles has been studied. Four compositions corresponding to different ceramic pigments chrome-tin pink, cobalt-ferrite black, pink coral of iron in zircon and pink of chromium-tin sphene have been prepared. Compositions using several synthesis methods ceramic route and nonconventional methods have been prepared and fired by microwave riatermia in a multimode, W power and MHz frequency, microwave equipment, and by conventional electric kiln.

Results show that the efficiency of microwave firing show a great dependence on the mixing degree of precursors attained on the synthesis methods carried out, on microstructural parameters of powders and on the considered pigmenting system.

Laser system with pulse lengths in the fsec regime are commercially available, the timing stability is a major concern. It is proposed a multi-cell W-band photoinjector that does not require a mode locked laser system. Thereby eliminating the stability requirements at W-band. The laser pulse is allowed to be many rf periods long.

In principle, the photoinjector can now be considered as a thermionic rf gun. Instead of using an alpha magnet to compress the electron bunch, which would have a detrimental effect on the transverse hase space quality due to longitudinal phase space mixing, it is here proposed to use long pulse laser system and a pair of undulators diatermis produce a low emittance, high current, ultra-short electron bunch for beam dynamics experiments in the 90 Duatermia regime.
