14. Laminated composite based on polyester geotextile fibers and polyurethane resin for coating wood structures
New environmental laws have restricted the use of hardwood trees in overhead power lines structures, such as, poles and cross-arms, leading companies to seek alternative materials. Reforested wood coated with polymeric resin has been proposed as an environmental friendly solution, with improved electrical properties and protection against external agents, e.

16. Emergency double-J stent insertion following uncomplicated Ureteroscopy: risk-factor analysis and recommendations
Purpose Emergency double-J (DJ) stenting following “uncomplicated” ureteroscopic (UURS) stone treatment is both morbid and costly. Our study aims at identifying those patients who are more likely to require such an extra procedure. Handling of this complication will also be highlighted. Materials and Methods 319 cases of UURS cases were selected out o

18. Critérios para o design de estação de trabalho informatizada residencial / Criteria for the design of computerized residential workstation
This study investigates the computerized workstation incorporated to the residential place. The technology of equipment of informatics replaced the importance given to the writing-desk. The place taken by the old writing desk -- which attended the house administration -- started to compete with the computer work place besides its peripheral pieces and office

19. Roof modular system in wood and particle board (OSB) to rural construction
Wood is a material of great applicability in construction, with advantageous properties to form various structural systems, such as walls and roof. Most of the roof structural systems follow models that have remained unchanged for a long time. A roof modular system in distinguished materials is proposed: reforested wood (Pine), oriented strand board (OSB) an

20. Sensores e biossensores baseados em transistores de efeito de campo utilizando filmes automontados nanoestruturados / Sensors and biosensors based on field-effect transistors using nanostructured self-assembled films
Separative extended gate field-effect transistor (SEGFET) device is an alternative to the conventional ion-sensitive field-effect transistor (ISFET). The great advantage of SEGFET refers to its easy processing, i.e., it is limited under only manipulation of the gate electrode, avoiding the conventional microelectronic processes. In this way, ion sensors and

23. Estudo da viabilidade para fabricação de fibra óptica polimérica (FOP) por extrusão vertical / Study of the feasibility on manufacturing polymeric optical fiber (POF) by vertical extrusion
Polymeric optical fibers (POF) presents some advantages compared to the glass optical fibers as flexibility, higher numerical aperture (NA), ease in handling and connecting due to their larger diameter and lower cost manufacturing and installation. However, due to their larger transmission losses compared to the main applications of glass fibers, POF are lim

24. 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
