Dicionário e cores

O léxico de uma língua pode ser considerado um bem ou um conjunto de bens lingüísticos pertencente a uma sociedade de importância e valor reconhecidos num determinado lugar, região ou país que, devido ao progresso técnico e científico, evolui em continuidade, nas mais diversas frentes, uma vez que o processo de nomeação da realidade é uma constante dinâmica e vivaz. É nesse conjunto imenso de unidades lexicais, cujas divergências lingüístico-semânticas são inerentes e formadoras de culturas e comunidades de fala, que se inserem os itens lexicais cromáticos como microssistemas lingüísticos singulares repletos de significação e riqueza sintático-semântico-pragmática. No microssistema das cores, esse universo lexical abarca tipos de combinações fixas das mais variadas espécies, de forma representativa e peculiar. Nesta exposição, tratarei, especificamente, daqueles proverbiais e das expressões fixas, por meio de considerações de cunho teórico e prático concernentes à sistematização e à busca dessas expressões lexicais no processo de elaboração de uma obra lexicográfica especial, no caso, um Dicionário Multilíngüe de Cores – DMC.

Suitability of carbon fiber-reinforced polymers as power cable cores: Galvanic corrosion and thermal stability evaluation

The increasing demand for electrical energy and the difficulties involved in installing new transmission lines presents a global challenge. Transmission line cables need to conduct more current, which creates the problem of excessive cable sag and limits the distance between towers. Therefore, it is necessary to develop new cables that have low thermal expansion coefficients, low densities, and high resistance to mechanical stress and corrosion. Continuous fiber-reinforced polymers are now widely used in many industries, including electrical utilities, and provide properties that are superior to those of traditional ACSR (aluminum conductor steel reinforced) cables. Although composite core cables show good performance in terms of corrosion, the contact of carbon fibers with aluminum promotes galvanic corrosion, which compromises mechanical performance. In this work, three different fiber coatings were tested (phenol formaldehyde resin, epoxy-based resin, and epoxy resin with polyester braiding), with measurements of the galvanic current. The use of epoxy resin combined with polyester braiding provided the best inhibition of galvanic corrosion. Investigation of thermal stability revealed that use of phenol formaldehyde resin resulted in a higher glass transition temperature. On the other hand, a post-cure process applied to epoxy-based resin enabled it to achieve glass transition temperatures of up to 200 degrees C. (C) 2014 Elsevier Ltd. All rights reserved.

As cores da fauna e da flora: um dicionário especial composto por cromônimos

This work aims to talk about some considerations arisen from the process of elaboration of a special dictionary composed of chromatic phrases found in Botanic and Zoology domains, as well as to present its macrostructure and microstructure. Our efforts are concentrated on creating a simple and complete structure, which may be the most adequate for the audience, i.e., for specialists and students connected to the Environment area.

Léxico e cores: as expressões cromáticas contribuindo para a ampliação lexical

The lexicon is the cultural heritage of a people. It is composed by the linguistic and extra-linguistic experience gained over the years and consists of different systems, among them the lexical set of colors that has collaborated on lexical expansion in common discourse as well as in specialized discourse, providing the interaction and equilibrium among the different levels of specialization of discourse. This work aims at talking about the role of the field of colors in formation of new lexical units in Botany and Zoology, as well as its performance in the intersection between the common and specialized discourse.

Com quantas cores se narra uma saudade? o narrador infantil e a leitura do real em um texto de Lygia Bojunga

El carácter pedagógico de la literatura infantil ha servido, por largo tiempo, como factor de desprestigio del género, ya sea por la imposición de paradigmas comportamentales advenidos de una postura autoritaria de los adultos, subyacente al texto, ya sea por haber minimizado la preocupación artística del lenguaje. Este artículo analiza de que manera la narrativa O meu amigo pintor, de Lygia Bojunga, supera ese modelo, al instaurar un equilibrio entre el respeto al universo en formación de los niños y los medios lingüísticos que representan el universo infantil desde la mirada de la propia creatura, facultándole a ella la elaboración de sus significados.

Reconhecimento de cores de objetos e de alimentos de cromaticidades opostas por pintos de corte

The aim of this research was to evaluate, by preference tests, the ability of perception of broiler chicks in the recognition of objects and foods of different colors. The survey was conducted in Brazil and consisted in the conditioning of 60 sexed one-day-old chicks using 30 male chicks and 30 female chicks for three days with blue balls and red food colors chosen for having opposed chromaticities. After the conditioning phase, a preference test was performed, in which the animals were placed individually in the center of an arena test with four options: red food, blue food, red balls and blue balls. Each bird was measured for 10 minutes. Latency to the first peck and the number of pecks, the number of sequential pecks at each object type or food, the total time the bird in each occupied compartment and the first occupied slot were recorded. According to the results, female chicks are less inhibited when in contact with a new situation when compared with males. However, males were able to establish a standard environment in the conditioning phase and opted for the compartment which was closer to that situation, associating the blue color to the ball and red color to the food. Overall, among the types of object colors and between types of food colors, the birds took less time for the decision on the choice of blue food and blue ball, showing a greater attraction, at first, to this color. Between the two ball colors, shorter latency period, greater number of interactions as well as more time spent on site were related to the blue sphere, verifying greater preference for this object. When evaluating the types of food colors, it was observed that the highest averages related to the number of pecks, and sequential pecks occurred with red food. Therefore, it is concluded that the birds recognized the red and blue food object, with the blue color having greater attractiveness for broiler chicks when compared to red.

As cores e suas possibilidades plásticas

This study was idealized in order to understand the universe of colors in the visual arts and in our lives. The color itself is a mystery even today. Even it has already been explained by several scientists, theorists and experts in our lives, the color is too complex for our understanding and feelings. Every day we see real examples of how colors act in our bodies, in our brains, and our tastes, colors influence us at all. And through this work we can understand a little of the physiological side, and how the color was used in our daily life and the arts
