1. Análise das propriedades físicas e mecânicas de blocos de concreto prensados sem função estrutural com incorporação de PET reciclado
RESUMO O presente trabalho apresenta a análise de um elemento não convencional para sistema vedação de edificações: o bloco de concreto prensado com a incorporação de PET reciclado. Para tanto foi realizada uma análise experimental realizando-se a substituição, em volume, do agregado miúdo (pó de pedra) por PET triturado, nos teores de 15%, 30%

2. Effect of hydrofluoric acid concentration and etching time on resin-bond strength to different glass ceramics
Abstract: The objective of this study was to evaluate the effect of the hydrofluoridric acid (HF) concentration and time of acid conditioning on bond strength of three glass ceramics to a resin cement. Thus, fifty blocks (10 mm x 5 mm x 2 mm) of each ceramic (LDCAD: IPS e.max CAD; LCAD: IPS Empress CAD and LDHP: IPS e.max Press) were made and embedded in acr

3. The marginal fit of lithium disilicate crowns: Press vs. CAD/CAM
Abstract: This study aimed to compare the vertical marginal gap of teeth restored with lithium disilicate crowns fabricated using CAD/CAM or by pressed ceramic approach. Twenty mandibular third molar teeth were collected after surgical extractions and prepared to receive full veneer crowns. Teeth were optically scanned and lithium disilicate blocks were used

4. Produção de mudas de acácia colonizadas com micorrizas e rizóbio em diferentes recipientes.
Realizou-se um experimento em casa de vegetação, com o objetivo de avaliar diferentes métodos na produção de mudas de Acacia mangium Willd, colonizadas com fungos micorrízicos arbusculares (FMAs) e rizóbio. O delineamento experimental foi o inteiramente casualizado num esquema fatorial 4x2 (controle, FMAs, rizóbio e FMAs + rizóbio x blocos prensados

5. Adição de cascalho de perfuração da bacia potiguar em argilas para uso em materiais cerâmicos: influência da concentração e temperatura de queima.
One of waste produced on large scale during the well drilling is the gravel drilling. There are techniques for the treatment of the same, but there isnt consensus on what are the best in terms of economic and environmental. One alternative for disposal of this waste and objective of this paper is the incorporation and immobilization of gravel clay matrix to

6. Processing of bulk Bi-2223 high-temperature superconductor
The Bi2Sr2Ca2Cu3 O10+x (Bi-2223) is one of the main high temperature superconductors for applications. One of these applications is the Superconductor Fault Current Limiter (SCFCL), which is a very promising high temperature superconducting device. SCFCL's can be improved by using bulk superconductors with high critical currents, which requires a sufficientl

7. Estudo do acondicionamento de cafe torrado e moido em sistemas unitizados. / Study of the packing of roasted and ground coffee in unity system.
An alternative system to the packing of roasted and ground coffee was developed, using pression in the three different levels, 3t (P3), 6t (P6) e 9t (P9) to obtain 50g blocks. The objective of this study was obtain a safe and useful product comparing to the traditional system. The effect of the grind fine (M3), medium (M5) and coarse (M7) and press was deter

8. Ceramic characterization and factography of resin-ceramic adhesive interface after different ceramic surface treatments / Caracterização ceramica e avaliação fractografica da interface adesiva com resina, apos diferentes tratamentos de superficie
This study evaluated the effect of ceramic surface treatments on tensile bond strength (?) and the mode of failure of a resin bonded to two types of ceramics, testing the hypothesis that ? of ceramics to resin is controlled by the ceramic surface treatment. Methods: Ten blocks of each the hot-pressed leucite-based ceramic (E1- IPS Empress) and the two-phase

9. Produção de mudas de Acacia mangium Wild. e Mimosa artemisiana Heringer &Paula em diferentes recipientes, utilizando compostos de resíduos urbanos, para a recuperação de áreas degradadas. / Seedlings production of Acacia mangium Wild. and Mimosa artemisiana Heringer &Paula, in different recipients, using urban residues compound, to recover damaged areas.
Com o objetivo de testar metodologias para a produção de mudas de Acacia mangium e Mimosa artemisiana para recuperação de áreas degradadas, este trabalho avaliou substratos a base de composto de lixo urbano (CLU) + composto do resíduo de poda (CRP), nos seguintes percentuais de volume: S1: (90+0); S2: (70+20); S3: (45+45); S4: (20+70); S5: (0+90), todo

10. Aproveitamento de Lodo de Estação de Tratamento de Água em Cerâmica Vermelha
The water treatment stations (WTA) have been researching solutions for the recycling of the residue generated in the water treatment process this residue is called WTA mud. Presently, the adopted solutions are the releasing of the residue into sanitary landfills or into the sewer system. The red ceramics presents an enormous potential to contribute for the s

11. Avaliação experimental do comportamento estrutural de paredes não armadas, submetidas à compressão axial, construídas com tijolito
Unfortunately, researches involving the use of blocks set up without mortar and interlock have not been common. Tijolito is a soil-cement block, which can be used as a masonry component without the use of mortar in the horizontal joints. The wall stabilization is managed after the filling of the holes disposed in a way to fulfill this purpose, with fluid mor
