Comparative analysis between a CAD model design and physical models obtained by manufacturing additive technologies using optical scan

This article presents a detailed study of the application of different additive manufacturing technologies (sintering process, three-dimensional printing, extrusion and stereolithographic process), in the design process of a complex geometry model and its moving parts. The fabrication sequence was evaluated in terms of pre-processing conditions (model generation and model STL SLI), generation strategy and physical model post-processing operations. Dimensional verification of the obtained models was undertook by projecting structured light (optical scan), a relatively new technology of main importance for metrology and reverse engineering. Studies were done in certain manufacturing time and production costs, which allowed the definition of an more comprehensive evaluation matrix of additive technologies.

Stability of neutral functional differential equations in terms of measures

In this paper we investigate the relationships between different concepts of stability in measure for the solutions of an autonomous or periodic neutral functional differential equation.

Optimal placement of piezoelectric sensor/actuators for smart structures vibration control

Smart material technology has become an area of increasing interest for the development of lighter and stronger structures that are able to incorporate actuator and sensor capabilities for collocated control. In the design of actively controlled structures, the determination of the actuator locations and the controller gains is a very important issue. For that purpose, smart material modeling, modal analysis methods, and control and optimization techniques are the most important ingredients to be taken into account. The optimization problem to be solved in this context presents two interdependent aspects. The first is related to the discrete optimal actuator location selection problem, which is solved in this paper using genetic algorithms. The second is represented by a continuous variable optimization problem, through which the control gains are determined using classical techniques. A cantilever Euler-Bernoulli beam is used to illustrate the presented methodology.

Abortamento na adolescência: um estudo epidemiológico

O presente trabalho foi desenvolvido no Hospital Maternidade Santa Izabel da cidade de Bauru, São Paulo, Brasil, e teve como objetivo investigar o abortamento na adolescência e compará-lo com o das mulheres adultas. Os indicadores buscaram traçar o perfil epidemiológico das mulheres internadas, por meio de dados coletados em prontuários, entre aquelas com diagnóstico de aborto, independente da forma clínica, entre os anos de 2000 a 2003. O total de abortamentos registrados foi de 2.286, sendo 459 (20,08%) na faixa etária da adolescência e a forma completa foi significativamente maior nas adolescentes quando comparada às das mulheres adultas; segundo o ano de análise, constatou-se decréscimo de ocorrência entre as adolescentes, com maior incidência em 2000 (30,50%), seguida dos anos de 2001 (25,05%), 2002 (23,53%) e 2003 (20,92%), sendo que as adolescentes apresentaram tendência a permanecer dois ou mais dias hospitalizadas. Enfatiza-se a implementação de políticas e programas direcionados à saúde sexual e reprodutiva e suas co-morbidades.

Use of Facial Protection to Prevent Reinjury During Sports Practice

The objective of the study was to report the prevention of facial reinjury of a volleyball player using a custom-made protective facial shield. A custom-made protective partial facial shield was fabricated using polymethylmethacrylate and was fitted with a soft lining material to provide additional comfort and protection to the injured area. Facial protection provides greater security against possible facial injuries and allows injured areas to recover during sports practice.

Saliva: reflection of the body

Saliva has become an important resource for evaluating physiological and pathological conditions in humans. The use of saliva has many advantages, including the simple and non-invasive method of collection and its easy, low-cost storage. With the addition of modern techniques and chemical instrumentation equipment, there has been an increase in its use for laboratory investigations, applicable for basic and clinical analyses in the fields of medicine and dentistry. The value of these methods for the diagnosis of oral and systemic diseases has been the subject of study by several researchers with the aim of increasing its use alongside complementary exams.

Population biology of Uca thayeri Rathbun, 1900 (Brachyura, Ocypodidae) in a subtropical South American mangrove area: Results from transect and catch-per-unit-effort techniques

The population biology of Uca thayeri was studied in a subtropical mangrove in Ubatuba, State of São Paulo, Brazil. Two sampling techniques were used: transect sampling and catch-per-unit-effort. Size frequency distribution, sex-ratio, and reproductive period were analysed. For juvenile crabs (CW < 4.6 mm), the transect procedure was most efficient, while ovigerous females were most collected during the capture effort. Males were most numerous in the transect technique, while in the catch-per-unit-effort there was no difference between sexes. The species showed a different size frequency distribution for each sampling procedure. The reproduction of U. thayeri is seasonal, being more pronounced in the warmer months of the year. However, juveniles occurred all over the year, although more numerous in the colder months. The success of the species in reproductive activity and the constant colonization of the area can be attributed to the availability of food resources and differential occupation of the habitat by ovigerous females.

A review of new vibration issues due to non-ideal energy sources

We analyze the dynamical coupling between energy sources and structural response that must not be ignored in real engineering problems, since real motors have limited output power. We present models of certain problems that render descriptions that are closer to real situations encountered in practice.
