2. Pre-heating mitigates composite degradation
ABSTRACT Dental composites cured at high temperatures show improved properties and higher degrees of conversion; however, there is no information available about the effect of pre-heating on material degradation. Objectives This study evaluated the effect of pre-heating on the degradation of composites, based on the analysis of radiopacity and silver penet

3. Screw loosening of different UCLA-type abutments after mechanical cycling
AIM: To evaluate the loss of applied torque (detorque) values in cast and pre-machined abutments for external hex abutment/implant interface of single implant-supported prostheses subjected to mechanical cycling. METHODS: Ten metal crowns were fabricated using two types of UCLA abutments: cast and pre-machined with metal base in NiCrTi alloy and tightened to

4. Fracture resistance of endodontically treated teeth restored with different intraradicular posts with different lengths
AIM: This study compared the resistance to fracture of endodontically treated teeth restored with different intraradicular posts with different lengths and full coverage metallic crowns. METHODS: Sixty extracted human canine teeth were randomly divided into 6 groups. Groups CP5, CP75 and CP10 were restored using custom cast post and core (CP) and groups PF5,

5. Análise numérica de painéis pré-moldados de fechamento em edificações de pequena altura / Numerical analysis of precast panels in small height buildings
Abstract: The civil construction has intensified efforts in the search and implementation of strategies for the modernization of the sector, in which the rationalization of constructive processes has a crucial role. The most notable trends are related to employment of systems, wholly or partly pre-fabricated, able to maximize the potential of rationalization

6. Estratégias de flexibilidade na arquitetura residencial multifamiliar / Strategies of flexibility in the multifamily residential architecture
A arquitetura residencial coletiva, representada pelos edifícios multifamiliares voltados para as massas que habitam as áreas urbanas, é o maior protagonista da arquitetura cotidiana, desde o início do século XX, período que desenvolveu, propagou e consolidou o repertório formal, normativo e estético dessa célebre tipologia. As motivações que impu

7. Reconstruction of bony facial contour deficiencies with polymethylmethacrylate implants: case report
Facial trauma can be considered one of the most serious aggressions found in the medical centers due to the emotional consequences and the possibility of deformity. In craniofacial surgery, the use of autologous bone is still the first choice for reconstructing bony defects or irregularities. When there is a shortage of donor bone or a patient refuses an int

8. Desajuste marginal e influencia na pre-carga de parafusos e nas tensões induzidas as fixações de pilares metaloplasticos sobre-fundidos / Marginal misfit and influence in the pre-load and the stress-induced setting of the metaloplastic abutments
Castable UCLA abutments are of wide applicability in dental implants, because they allow the manipulation in the laboratory at low cost and individualization of abutments for each patient. However, they show the worse results of marginal adaptation then the fabricated, although these aggregate costs significantly higher. UCLA premachined abutments for castin

9. An estimation method for gate delay variability in nanometer CMOS technology
In the nanoscale regime of VLSI technology, circuit performance is increasingly affected by variational effects such as process variations, power supply noise, coupling noise and temperature changes. Manufacturing variations may lead to significant discrepancies between designed and fabricated integrated circuits. Due to the shrinking of design dimensions, t

10. Uso dos resíduos da construção civil para a produção de pavimento intertravado a base de concreto de cimento portland e escória
Construction and demolition are two steps where the generation of waste is imperative, given the low industrialized processes. Due to the growth of cities, the demand for raw materials is becoming more expressive and their deposits more distant from consumer centers. Consequently there is an increase in the generation of rubble and storage areas. The granula

11. Medicina paliativa e análise de discurso crítica : identidade, ideologia e poder
This thesis results from a research study based upon Critical Discourse Analysis (ADC) that sought to investigate identitary representations in palliative or terminal diseases at a public health unit in Brasilia, the Federal District. In order to conduct this research, ethnographic methods were applied in order to generate and collect data. The methods selec

12. Fabricação e caracterização de termopares Cu/CuNixPy obtidos por deposição eletroquímica. / Fabrication and characterization of Cu/CuNixPy thermocouples obtained by electroless deposition.
In this work, it was studied chemical depositions of CuNixPy alloys and it was fabricated Cu/CuNixPy thermocouples onto silicon wafer surfaces. Initially, surfaces were pre-activated in a diluted hydrofluoric acid solution containing PdCl2. Following, it was used a de-ionizedwater- diluted alkaline chemical bath containing 15 g/l NiSO4.6H2O; 0,1-0,3 g/l CuSO
