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

Three-dimensional aspects of the lingual papillae and their connective tissue cores in the tongue of rats: a scanning electron microscope study

The aim of the present study was to describe the tridimensional morphological characteristics of the lingual papillae and their connective tissue cores (CTCs) in Sprague Dawley rats. Four types of papillae were reported on the dorsal surface. Filiform papillae were distributed on the tongue surface and after epithelial maceration a conic and multifilamentary shape of the CTCs was revealed. Fungiform papillae were reported on the rostral and middle regions covered by a squamous epithelium. After the removal of the epithelium, the shape of a volcano with the taste orifice at its top was noted. Foliate papillae were composed of five pairs of epithelial folds situated on the lateral-caudal margin of the tongue. After the removal of the epithelium, they were shown to be limited by thin laminar projections. The vallate papilla with an oval shape was present in the caudal region and delimited by an incomplete groove. The morphological characteristics of the lingual papillae of Sprague Dowley rats, three-dimensional SEM images, and the types of papillae on the dorsal surface were similar to those reported previously in other rodent mammals. The maceration technique revealed the details of extracellular matrix with varied shapes form of connective tissue cores.

Reabilitação estética com enfoque nas diferentes cores de substratos e na escolha da cor do cimento adesivo

The evolution of techniques and materials applied to adhesive ceramic restorations resulted in the intensification of its use, proving to be an excellent method of aesthetic restoration. Some important features of this technique are its conservative preparation, which avoids an excessive loss of tooth structure and its high aesthetic value provided by the ceramic even when utilized under different color of dental substrates. The aim of this paper was to report a clinical case with full crowns, porcelain veneers and non-prep veneers, enhancing peculiarities related to the material used, tooth preparation techniques, cementing, indications and contraindications.

As cores e sua influência no processo projetual

In current days, the technology in materials and compounds makes it possible to implement a wide range of colors in any production process is this graphic or product. Formerly the limitations of series production allowed a small variety of colors and reasons, and the consumer had access to few options at the time of purchase. Today the companies make use of color in ceaseless products in order to differentiate them from competitors, which awakens an alert during the creative process of designer: How To properly apply the colors to the products? This Article aims at helping these professionals to understand how it works the Chroma spectrum in their physiology and psychology in such a way as to demonstrate a method to create a palette of colors directed to the user to whom you want to reach. This methodological suggestion, among other possible, should facilitate the process of choice of colors by professional during the creative process and projectual.

High-Pressure Micellar Solutions of Polystyrene-block-polybutadiene and Polystyrene-block-polyisoprene in Propane Exhibit Cloud-Pressure Reduction and Distinct Micellization End Points

Micellar solutions of polystyrene-block-polybutadiene and polystyrene-block-polyisoprene in propane are found to exhibit significantly lower cloud pressures than the corresponding hypothetical nonmicellar solutions. Such a cloud-pressure reduction indicates the extent to which micelle formation enhances the apparent diblock solubility in near-critical and hence compressible propane. Concentration-dependent pressure-temperature points beyond which no micelles can be formed, referred to as the micellization end points, are found to depend on the block type, size, and ratio. The cloud-pressure reduction and the micellization end point measured for styrene-diene diblocks in propane should be characteristic of all amphiphilic diblock copolymer solutions that form micelles in compressible solvents.

Process for producing biodiesel fuel with reduced viscosity and a cloud point below thirty-two (32) degrees fahrenheit

Triglycerides are reacted in a liquid phase reaction with methanol and a homogeneous basic catalyst. The reaction yields a spatially separated two phase result with an upper located non-polar phase consisting principally of non-polar methyl esters and a lower located phase consisting principally of glycerol and residual methyl esters. The glycerol phase is passed through a strong cationic ion exchanger to remove anions, resulting in a neutral product which is flashed to remove methanol and which is reacted with isobutylene in the presence of a strong acid catalyst to produce glycerol ethers. The glycerol ethers are then added back to the upper located methyl ethyl ester phase to provide an improved biodiesel fuel.

Historical record of polycyclic aromatic hydrocarbons (PAHs) and spheroidal carbonaceous particles (SCPs) in marine sediment cores from Admiralty Bay, King George Island, Antarctica

This paper describes the first results of polycyclic aromatic hydrocarbons (PAHs) and spheroidal carbonaceous particles (SCPs) in sediment cores of Admiralty Bay, Antarctica. These markers were used to assess the local input of anthropogenic materials (particulate and organic compounds) as a result of the influence of human occupation in a sub-Antarctic region and a possible long-range atmospheric transport of combustion products from sources in South America. The highest SCPs and PAHs concentrations were observed during the last 30 years, when three research stations were built in the area and industrial activities in South America increased. The concentrations of SCPs and PAHs were much lower than those of other regions in the northern hemisphere and other reported data for the southern hemisphere. The PAH isomer ratios showed that the major sources of PAHs are fossil fuels/petroleum, biomass combustion and sewage contribution generally close to the Brazilian scientific station.
