Application of Thermochromic Liquid Crystal to Rotating Surfaces
No full textEncapsulated thermochromic liquid crystal (TLC) can be used to measure the surface temperature of stationary or rotating bodies. However, some research workers have reported a “rotational shift”: When the temperature of a rotating body is measured by thermocouples and TLC, there is a difference between the two sets of temperatures, and this difference increases with increasing rotational speed. Two research groups (Camci and Glezer in the USA, and Owen, Pilbrow, and Syson in the UK) have independently examined the effect of speed on TLC applied to the surfaces of rotating disks. The USA group used narrow-band TLC on a disk of 305 mm diameter rotating up to 7500 rpm measuring the surface temperature using an infrared (IR) sensor. The UK group used wide-band TLC on a disk of 580 mm diameter rotating up to 7000 rpm, measuring the temperature with an IR thermal imager. Both groups used the so-called hue technique to evaluate the temperature of the TLC and concluded that, even for centripetal accelerations in excess of 104 g, there is no significant effect of rotational speed on either narrow-band or wide-band TLC. It is suggested that the “rotational shift” observed by some researchers was probably caused by thermal-disturbance errors, which affected the thermocouples, rather than by changes in the TLC.</jats:p
The process of TV mini-series based on historical events´production: the romanticized past
No full textO trabalho que apresentamos tem como objeto de estudo a teledramaturgia baseada em acontecimentos históricos. Selecionamos como fonte duas minisséries de cunho histórico: A Muralha e Um Só Coração, produzidas pela TV Globo, e destacamos a autora Maria Adelaide Amaral. O objetivo inicial era comparar as narrativas ficcionais com o conhecimento histórico. Porém, no decorrer da pesquisa encontramos um produto cultural coletivo e industrial que se utiliza de informações históricas para construir uma narrativa ficcional particular. As minisséries históricas foram selecionadas por tratarem a respeito de temas relativos à história da cidade de São Paulo. Ao comparar a ficção com a produção historiográfica, conseguimos identificar algumas das fontes utilizadas e as transformações realizadas. Verificamos que as narrativas ficcionais da teledramaturgia baseadas em acontecimentos históricos se estruturam com a lógica da ficção romanesca, por integrarem a linguagem de um folhetim televisivo. As informações históricas são diluídas no pitoresco, no exótico, no diferente, mas acabam sendo assimiladas pelo público telespectador como imagens da verdade históricaThis dissertation aims to study TV dramas based on historical events. The two selected works for analysis are mini-series dealing with historical narratives: A Muralha and Um Só Coração, produced by Globo Networks - Brazil, also stressing out the work of their author, Maria Adelaide Amaral. The initial goal in this study was a comparison between fictional narratives and historical knowledge. However, developing the subject allowed us to work with a collective cultural and industrial product, which uses the historical information in order to build an unique fictional narrative. These two mini-series based on historical events were selected because they both relate to aspects of the history of São Paulo city. In comparing fiction with the historiographical studies, we were able to identify some of the sources which were used, as well as the transformations that have occurred at the mini-series. We can see that the fictional narratives in television drama, even based in historical events, are structured according to the logic of romantic fiction. The historical information is diluted into the pitoresque, the exotic, the distinctive, but is still understood by the average viewer an image of the historical trut

No full textMechanical Behavior of Fe- and Co-Based Amorphous Alloys after Thermal Action
No full textThe effect of heat treatment on the structure and mechanical properties of Co-Fe-Cr-Si-B/Fe-Cr-B/Fe-Ni-B amorphous alloys has been studied systematically. Melt-quenching (spinning method) was used for production of investigated amorphous alloys. The transmission electron microscopy (TEM) was used to study the structure transformations. The effect of temperature on deformation behavior (plasticity, microhardness, crack resistance, and the density and average length of shear bands) of the amorphous alloys was studied by bending and microindentation. It is shown that the ductile–brittle transition, which occurs at the stage of structure relaxation in amorphous alloys, is caused by two factors: a decrease in the susceptibility of the amorphous matrix to plastic flow and an abrupt decrease in the resistance to the development of quasibrittle cracks. It is established that the transition to a two-phase amorphous–nanocrystalline state upon annealing leads to substantial strengthening of the alloys and a partial recovery of their plasticity. It is proved that the strengthening of amorphous alloys at the initial stages of crystallization can be initiated by the difference in the elastic moduli of the amorphous matrix and the precipitated nanocrystals, as well as by the specific features of the interaction between nanocrystalline phase particles and shear bands propagating under external actions. It is established that the phenomenon of plasticization in amorphous alloys (the crack resistance can increase after annealing in a certain temperature range) is due to the effective retardation of cracks on nanoparticles
