Influência do agente de união na resistência ao cisalhamento da interface titânio/polímero de vidro

There is little information regarding bond strengths of polyglass to metal alloys. This study evaluated the influence of bonding system on shear bond strength of a composite resin (Artglass/Heraeus Kulzer) to cast titanium (Ti). Twenty metallic structures (4mm in diameter, 5mm thick) of titanium grade I were cast shaped and abraded with 250mm aluminum oxide and separated into two groups. For each group was applied one bonding system (Siloc or Retention Flow) before opaque and dentin polymer superposition. This procedure was managed using teflon matrices. They were manipulated and polymerized according to the manufacturer's recommendations. The samples were stored in distilled water for 24 hours at 37º and thermocycled (5º and 55ºC/500 cycles). Shear bond strength tests were performed by using an Instron Universal testing machine at a crosshead speed of 5mm/min. Results were analyzed statistically with one-way ANOVA (a=0,5) and they indicated that the Retention Flow system was statistically better than Siloc (20.74 MPa and 11.65 MPa , respectively). It was possible to conclude that the bonding agent influenced the adhesion between polymer and cast titanium.

Avaliação da Saccharomyces cerevisiae como agente ligante na técnica de difusão em filmes finos por gradiente de concentração (DGT) para a determinação de metilmercúrio

Sabendo-se do potencial de toxicidade do mercúrio, mais especificamente de sua forma orgânica, o metilmercúrio (MeHg), faz-se necessária a busca por métodos analíticos eficientes e precisos para a determinação e especiação do metal. A técnica de difusão por gradiente em filmes finos (DGT) já vem sendo utilizada para tal fim de maneira eficiente tendo apresentado resultados satisfatórios em diversos estudos. Porém, a utilização de ligantes alternativos aos convencionais, que tornem a aplicação da técnica menos custosa em termos laborais e financeiros, faz-se importante para um monitoramento constante e eficiente do metilmercúrio no ambiente. No presente trabalho buscou-se avaliar o potencial da levedura Saccharomyces cerevisiae imobilizada em agarose em combinação com a poliacrilamida como agente difusivo para determinação seletiva de MeHg. Os resultados demonstraram-se positivo, com um coeficiente de difusão médio de 7,03 ± 0,77 x 10-6 cm2 s-1. Os resultados demonstraram também baixa influencia do pH, força iônica e outros íons na retenção do analito pelos dispositivos. As recuperações de Hg2+ demonstraram-se insatisfatórios, evidenciando a seletividade dos dispositivos

Avaliação clínica do clareamento no consultório: técnica de aplicação única do agente clareador

This study aimed to evaluate the clinical effectiveness of two bleaching agents without changing the whitening gel during the clinic session 1X45minutos. 10 patients were selected according to the criteria of inclusion and exclusion and upper arch of the patients were divided into two quadrants (n: 10), G1: gel clareador Clàriant Office (hidrogênio35 Angellus) peroxide% (PH) in superior right side (LD) and the gel WhitenessHp Blue (FGM) PH 35% on the superior left side (LE. 2 clinical sessions were accomplished, 45 minutes each, with an interval of one week between sessions. At first the bleaching treatment patients received prophylaxis, molding to guide measurement of color with condensation silicon and the color evaluation through the apparel spectrophotometer VITA Easyshade (Vita Zhanfabrik, Alemanhã). 14 days after the end of the bleaching treatment was performed the measurement final color of the teeth. The patients reported sensitivity in scale 0-4. The result showed that through T Test comparing quadrants presented no statistical differences (p>0,05) in relation to coloration and dental sensibility. It can be concluded that the materials evaluated are effective for bleaching vital teeth with low tooth sensibility.

Design & seleção de materiais: elaboração e execução de um sistema de informações para projeto do produto: madeiras

Wood is a renewable material and has unique characteristics that stem from its orthotropic properties. The objective of this study was to develop and implement an informational Selection of Materials and Manufacturing Processes appropriate to the activity of Product Design - Woods. Composed of a Digital Information System, distributed, and an ordered collection of samples. The design of a product, carries with it the choice of material, and the choice of a manufacturing process. Information on materials and manufacturing processes are available with different content, media and interfaces. However, such information is not systematized so that they can be recovered, as the need for the designer, especially on wood. This set of methods is called the Selection of Materials and Manufacturing Processes. It is hoped through this study that the methodologies for SMPF are employed by product designers, architects and engineers in Brazil.

Música popular e resistência: emergência de um agente folkcomunicacional a partir de um caso de conflito ambiental

Tralcao, situated in the Rios region, named after the various rivers that flow nearby, in Chile, is bathed by the Pichoy River and it encounters the rivers Estero Colliaico and Cruces. A cellulose company was established there back in 2004, and since the it has been dumping waste in the Cruces river, causing grave environmental issues and bringing severe consequences to the region. In the middle of the crossfire, we find Mr. Francisco Manquecho, considered to be an opinion leader according to Luis Beltrão, who assesses the real situation in the region throughout his song lyrics, acting as a propagator of the resistance against the environmental degradation occurring in Tralcao. Francisco acts as a ‘folkcommunicacional’ agent by spreading a non-hegemonic bias through his songs. The objective of this article is to show how an opinion leader acts in a context of environmental degradation in Tralcao region using the basis of the Folkcommunication Theory and the communicational processes which involve music as a concrete action of popular resistance.

Comportamento do maracuajazeiro amarelo, variedade Afruvec, ante uma população de Fusarium solani, agente causal da podridão do colo

The objective of the present work was to verify the behavior of yellow passion fruit, Afruvec variety, in relation to a population of Fusarium solani, obtained from this crop. The experimental delineation was random blocks, containing 10 treatments [9 isolates and 1 control treatment], with 4 repetitions, each plot being represented by a vase containing a plant. A disk of culture medium colonized by each isolate of the fungus was inoculated in the wounded collar region of the plants of the Afruvec variety two months after sowing. The appraised parameters were: the pathogenicity, the incidence (number of dead plants) and the severity of the disease (length of the lesion in the collar region), until 60 days after inoculation. The Afruvec variety was susceptible to the fungus and also presented variability as to the severity of the disease and incidence in relation to the different isolates. The population of the fungus showed variability in regard to aggressiveness. In light of the evidence of genetic diversity in the F. solani population, it is also suggested, in the tests of selection of materials to the pathogen, that these materials should be evaluated in different places with a history of the disease or inoculation with a pool of isolates of the fungus, in order to know the wide resistance of the genotype to the pathogen.

Benefícios na execução de uma obra sustentável em contrapartida aos métodos tradicionais da construção civil

The civil construction sector in Brazil is, simultaneously, a necessity that drives the economy and an evil that degrades the environment. Simple choices adopted in an enterprise can make big difference in harm caused by constructive practices, minimizing its harmful to the environment and making it sustainable. These choices, however, involve the use of materials and techniques often unknown by the builders, since the construction industry is very traditional. Even worse, the eco-friendly materials and sustainable techniques also face another obstacle to its use: the prejudice. Builders and customers prefer traditional methods to sustain belief that they present lower quality and higher price. This work raises awareness of the urgency with traditional methods must be overridden, showing practical and simple ways for this replacement, as well as confirm the quality equal to or even higher in the use of alternative materials and techniques, without addition in cost. Thus, the benefits are generated for all parties involved, from builders to residents
