1. Biomechanical Analysis of Locking Reconstruction Plate Using Mono- or Bicortical Screws
This experimental in vitro study evaluated the influence of screw length on the mechanical properties of a locking reconstruction plate designed with locking rings inserted into plate holes. Synthetic bone cylinders with 10 mm fracture gap and seven-hole locking reconstruction plates were used. Two groups of bone-plate constructs were assembled: Group 1 –

2. Physicochemical properties of endodontic sealers of different bases
OBJECTIVE: To assess the setting time (ST), flow (FL), radiopacity (RD), solubility (SB) and dimensional change following setting (DC) of different sealers (AH Plus®, Polifil, Apexit Plus®, Sealapex®, Endométhasone® and Endofill®) according to American National Standards Institute/American Dental Association (ANSI/ADA) Specification 57.

3. Biomechanical in vitro evaluation of three stable internal fixation techniques used in sagittal osteotomy of the mandibular ramus: a study in sheep mandibles
Among the osteotomies performed in orthognathic surgery, the sagittal osteotomy of the mandibular ramus (SOMR) is the most common, allowing a great range of movements and stable internal fixation (SIF), therefore eliminating the need of maxillomandibular block in the postoperative period. OBJECTIVES: The purpose of this study was to evaluate the biomechanica

4. Reusing of fine quarries in paving: a technical and economical approach / Reaproveitamento de finos de pedreiras em pavimentação: uma abordagem técnica e econômica
The wastes generated by the quarry companies from civil construction represent an activity that has been outstanding because of the countless problems that appear with their stockpiling and maintenance. The great concern with those wastes is linked to the capacity to generate social and environmental effects that can harm the ambient through the appearance o

5. Prova de carga rápida com recalque estabilizado / Stabilized settlements by quick maintained load test
The slow mantained load is a traditional test in foundations engineering worldwide. Nevertheless, its implementation may take too long, so there have been attempts to reduce its duration. The quick mantained load test, in other hand, takes only a few hours to be accomplished and the obtained settlements are lower than the slow maintained load test. The metho

6. CaracterizaÃÃo de um fÃmur sintÃtico empregando o mÃtodo dos elementos finitos e validaÃÃo por extensometria Ãtica / Characterization of a sintetic femur with the employment of the finite element method and validation by optical extensometry
This work makes use of sensors based on fiber Bragg gratings, for the validation of a numerical model on the finite elements method of a synthetic femur, produced by SawbonesÂ. The numerical model was developed from a numerical model already used at the University of Aveiro. For validation, was developed a system for setting and implementation of load steps

7. Estudo biomecanico de tres tecnicas diferentes de fixações metalicas utilizadas em osteotomia sagital do ramo mandibular / Biomechanical evaluation of three different techniques of rigid fixation in sagital split ramus osteotomy
Studies have considered many techniques and methods of rigid internal fixation (RIF) leads to obtain greater stability to the bone segments and minimum displacement of the condyles after performed the sagittal split ramus osteotomy (SSRO). In this way, the purpose of this study was to evaluate by means of mechanical compression testing model with synthetic h

8. A new miracidia hatching device for diagnosing schistosomiasis
It is still imperative to develop a parasitological technique highly sensitive for diagnosing schistosomiasis in epidemiological and individual surveys. A simple and cheap hatching device with a collecting container was manufactured and tested under experimental conditions. Twelve Kato-Katz slides were performed as golden standard for comparison. Quantitativ

9. Comparative biomechanical evaluation of flexion resistance between absorbable and metalic plate and screws used in mandibular body poliuretane / Estudo comparativo da resistencia mecanica a flexão de placas e parafusos reabsorviveis e metalicos utilizados em osteotomias de corpo em mandibulas de poliuretano
The meaning of this study was to evaluate and compare the resistance to flexion between metallic and absorbable plates and screws for rigid internal fixation. It was used synthetic hemimandible of polyurethane, in which one was performed a straight cut between second premolar and first molar, simulating a breaking of mandibular body. It was established two g

10. Estudo da inferência de carregamento em histórias de vôos simulados na liga de Al aeronáutico SAE-AMS 7475 T7351 / Loading study of inference in a simulated flights history using an SAE-AMS 7475 T7351 aluminum alloy.
The loading inference and the fractographic reconstruction of fatigue crack propagation rate in simulated flight stories, as Twist, mini-Twist, Falstaff and mini-Falstaff were investigated in this work. The studied material was an aluminum alloy SAE-AMS 7475 T7351. Tensile and hardness tests were carried out in order to determine mechanical properties, as we

11. Experimental and numerical analysis of cold-formed steel angles under tension and connected with bolts / Análise experimental e numérica de cantoneiras de aço formadas a frio, sob tração e conectadas por parafusos
This work is an experimental and numerical study of cold-formed steel angles connected with bolts and under tension loading. Due to the non-uniform straining of the tension- member when connected to the gusset plate, a debilitating phenomenon, known as the shear lag, takes place. This phenomenon is also investigated in this research. For the calculation of t
