This is a theoretical paper that seeks to work, through interrelations, concepts relating to contemporary aesthetics in parallel to phenomenon of perception. It begins with the aesthetic interaction between content and form in order to trace the development of perceptionexpression interaction, inserted into the mutual action of its physical and psychical aspects "through behind" a thinking mind. In order to generalize such interaction to reality itself as a natural and evolutionary cycle, we start from the analysis of perception of more complex organic beings, endowed with consciousness, to extend the question to the simplest organic beings, as even to inorganics. It is based upon principles of equilibrium and unity in diversity to highlight a historical fact that it seems undeniable: that man evolves and this evolution, their perception clears, while that is particularized your experience and aesthetic judgment. Having in the art, the activity can boost an evolution more profound while pleasurable.

A Cie. <<à fleur de peau>>, fundada em 1988 pela brasileira Denise Namura e pelo alemão Michael Bugdahn, sediada na França, desenvolve uma linguagem estéticoexpressiva própria, caracterizada por integrar áreas artísticas distintas, como a dança, as artes circenses, o teatro e a mímica. Tal confluência decorre da formação de ambos os fundadores, atuais diretores e coreógrafos da companhia de dança-teatro. O intercâmbio dessa companhia com o Brasil é constante, incluindo apresentações de seus espetácul os, coreografias para outras companhias e oficinas. Em uma de suas vindas à cidade de São Paulo, no ano de 2013, tivemos a oportunidade de entrar em contato com a pesquisa de linguagem da Cie. Em 2014, os fundadores foram convidados a coreografar um espetáculo infantil para a Cia. de Danças de Diadema, localizada no ABCDMR paulista. Este estudo partiu do interesse em conhecer o trabalho desenvolvido por Namura e Bugdahn. A partir desse encontro, pudemos observar, relatar e refletir sobre como ocorreu a tran smissão dessa linguagem estético-expressiva no processo de criação do espetáculo A Mão do Meio - Sinfonia Lúdica aos bailarinos da companhia diademense. Para tanto, acompanhamos os ensaios referentes ao espetáculo durante os períodos anterior e posterior à pré-estreia e à estreia oficial do espetáculo. Posteriormente, foi possível tecer outra reflexão, dessa vez sobre os elementos teatrais componentes dessa linguagem, que a tornam diferente em relação ao processo de criação artística e apresentação da obra

A energia dos ventos é uma abundante fonte de energia renovável, limpa e disponível em quase todos os lugares. A geração da eletricidade através de fontes alternativas de energia como a eólica e a solar ganha grande importância diante da situação mundial em relação à preservação do meio ambiente e da necessidade de depender menos dos combustíveis fósseis como fontes de energia. No Brasil, algumas medidas precisas de vento, realizadas recentemente em diversos pontos do território nacional, indicam a existência de um imenso potencial eólico ainda não explorado. Para tanto se faz necessário estudos e revisões bibliográficas dos métodos de descrição e dimensionamento do regime eólico bem como as suas aplicações. Para isso foi feito uma análise do recurso eólico disponível na Região de Botucatu, utilizando os principais métodos de análise estatística e de determinação da energia produzida por um aerogerador.

Water deficit is one of the factors which most limit agriculture yield and growth. Although sugar cane has moderate tolerance to drought, it presents high yield losses under the influence of this abiotic factor. Based on this fact, selection of genotypes tolerant to water stress may represent an alternative for decreasing the amount of water used for irrigation, while keeping or increasing yield. This study was performed in order to evaluate the performance of four sugarcane cultivars during initial development under water stress conditions, by means of morphological variables to select more tolerant genotypes to drought. The experiment was carried out in a greenhouse at the Department of Rural Engineering, College of Agricultural Sciences - UNESP/Botucatu – SP, from November 26th 2010 to April 5th 2011. A total of four sugar cane cultivars were evaluated (RB855453, RB92579, RB965902 and RB965917) under two treatments as follows: control (100% field capacity) and water stress (50% field capacity). Evaluations were performed at 0, 28 and 63 days after treatment application. The following morphological variables were analyzed: plant height, leaf area, leaf length, leaf width, number of green leaves, shoot and root dry matter. The RB855453 and RB92579 cultivars produced more shoot and root dry matter under water stress treatment, while the RB965902 and RB965917 cultivars had lower shoot and root dry matter production under the same conditions. Therefore, the RB855453 and RB 92579 cultivars can be considered tolerant while the RB965902 and RB965917 cultivars can be considered susceptible.

In cooperation with the Lower Platte South Natural Resources District for a collaborative study of the cumulative effects of water and channel management practices on stream and riparian ecology, the U.S. Geological Survey (USGS) compiled, analyzed, and summarized hydrologic information from long-term gaging stations on the lower Platte River to determine any significant temporal differences among six discrete periods during 1895-2006 and to interpret any significant changes in relation to changes in climatic conditions or other factors. A subset of 171 examined hydrologic indices (HIs) were selected for use as indices that (1) included most of the variance in the larger set of indices, (2) retained utility as indicators of the streamflow regime, and (3) provided information at spatial and temporal scale(s) that were most indicative of streamflow regime(s). The study included the most downstream station within the central Platte River segment that flowed to the confluence with the Loup River and all four active streamflow-gaging stations (2006) on the lower Platte River main stem extending from the confluence of the Loup River and Platte River to the confluence of the Platte River and Missouri River south of Omaha. The drainage areas of the five streamflow-gaging stations covered four (of eight) climate divisions in Nebraska—division 2 (north central), 3 (northeast), 5 (central), and 6 (east central).

Much effort has been devoted to understanding the function of extrafloral nectaries (EFNs) for antplantherbivore interactions. However, the pattern of evolution of such structures throughout the history of plant lineages remains unexplored. In this study, we used empirical knowledge on plant defences mediated by ants as a theoretical framework to test specific hypotheses about the adaptive role of EFNs during plant evolution. Emphasis was given to different processes (neutral or adaptive) and factors (habitat change and trade-offs with new trichomes) that may have affected the evolution of antplant associations. We measured seven EFN quantitative traits in all 105 species included in a well-supported phylogeny of the tribe Bignonieae (Bignoniaceae) and collected field data on antEFN interactions in 32 species. We identified a positive association between ant visitation (a surrogate of ant guarding) and the abundance of EFNs in vegetative plant parts and rejected the hypothesis of phylogenetic conservatism of EFNs, with most traits presenting K-values < 1. Modelling the evolution of EFN traits using maximum likelihood approaches further suggested adaptive evolution, with static-optimum models showing a better fit than purely drift models. In addition, the abundance of EFNs was associated with habitat shifts (with a decrease in the abundance of EFNs from forest to savannas), and a potential trade-off was detected between the abundance of EFNs and estipitate glandular trichomes (i.e. trichomes with sticky secretion). These evolutionary associations suggest divergent selection between species as well as explains K-values < 1. Experimental studies with multiple lineages of forest and savanna taxa may improve our understanding of the role of nectaries in plants. Overall, our results suggest that the evolution of EFNs was likely associated with the adaptive process which probably played an important role in the diversification of this plant group.

The success of magnetic hyperthermia cancer treatments rely strongly on the magnetic properties of the nanoparticles and their intricate dependence on the externally applied field. This is particularly more so as the response departs from the low field linear regime. In this paper we introduce a new parameter, referred to as the efficiency in converting electromagnetic energy into thermal energy, which is shown to be remarkably useful in the analysis of the system response, especially when the power loss is investigated as a function of the applied field amplitude. Using numerical simulations of dynamic hysteresis, through the stochastic Landau-Lifshitz model, we map in detail the efficiency as a function of all relevant parameters of the system and compare the results with simple-yet powerful-predictions based on heuristic arguments about the relaxation time.

The free-carrier absorption cross-section sigma of a magnetic colloid composed of magnetite nanoparticles dispersed in oil is obtained by using the Z-scan technique in different experimental conditions of the laser beam. We show that it is possible to obtain sigma with picosecond pulsed and millisecond chopped beams with pulse frequencies smaller than about 30 Hz. For higher pulse frequencies, the heating of the colloidal system triggers the appearance of the Soret effect. This effect artificially increases the value of sigma calculated from the experimental results. The limits of the different experimental setups are discussed. (C) 2012 Optical Society of America
