1. Broadband Antennas Based on the Double Moebius Strip
Abstract The family of new antenna designs based on the double Moebius strip principle is proposed in this article. Three possible options of the power supply port location had been reviewed in this respect: the cut external strip with the signal port located directly in the cut area is used; the continuous rings without discontinuities are applied, with the

3. Ultrasound monitoring of the uterus and ovaries of dominant and subordinate females of yellow-breasted capuchin (Sapajus xanthosternos) and robust tufted capuchin (Sapajus robustus) in captive colonies during the ovarian cycle and anestrus periods
RESUMO: O macaco-prego-do-peito-amarelo (Sapajus xanthosternos) e o macaco-prego-de-crista (Sapajus robustus) encontram-se em risco de extinção devido a destruição do seu habitat e a caça predatória. Porém, ainda necessita-se elucidar alguns detalhes de sua fisiologia reprodutiva, para obterem-se melhores índices por meio de reprodução assistida. S

5. Estudo experimental do fluxo de umidade em argamassas de cal aérea
RESUMO Uma parte significativa do património histórico construído ao redor do mundo é constituída de alvenaria estrutural, com juntas preenchidas com argamassa. Nesses sistemas estruturais, a argamassa usualmente representa uma parcela pequena/moderada do volume total da estrutura, no entanto, a argamassa é reconhecida como a principal fonte de movimen

7. An application of Earned Value Management (EVM) with Monte Carlo simulation in engineering project management
Resumo As rápidas alterações no mercado, faz que as empresas, cada vez mais, se orientem através de estruturas de projetos. Assim, um projeto difere de uma atividade rotineira pois é único, sendo gerenciado, e proporcionando benefícios esperados sem custos maiores que o previsto. Logo, deve-se planejá-lo e controlá-lo identificando os desvios entre

8. Ultimate bending capacity of aged fixed platform by considering the effect of marine fouling
Abstract For offshore structures, especially jacket supported structure such as fixed platform and offshore wind turbine, the underwater area provides an ideal site for corrosion formation and marine fouling. In this marine environment, the structures are exposed to particularly aggressive corrosion and colonized by marine organisms involving a diversity of

9. DISPLACEMENT MEASUREMENT IN SAWN WOOD AND WOOD PANEL BEAMS USING PARTICLE IMAGE VELOCIMETRY
ABSTRACT Throughout their useful life structures demand monitoring to verify their conditions of use. Thus, the need arises to seek methodologies capable to evaluate displacements and deformations in structural components of buildings. The objective of this research was to evaluate the use of the particle image velocimetry (PIV) technique to analyze test spe

10. Photodegradation of Fluoxetine Applying Different Photolytic Reactors: Evaluation of the Process Efficiency and Mechanism
Photolytic degradation of fluoxetine (FLX), a medicine commonly known as Prozac®, was evaluated by using different photochemical processes. The ultraviolet/microwave (UV/MW) process showed higher efficiency in all the aspects evaluated in this study. The energy consumption was equivalent to 1.94 × 10-4 kW h mg-1 L (UV/MW), while in the UV process the value

12. Structural Health Monitoring of Sandwich Structures Based on Dynamic Analysis
Abstract This work aims to contribute to the development of SHM systems based on vibration methods to be applied on sandwich structures. The main objective is focused on experimental damage identification via changes in the Frequency Response Function (FRF) with the usage of damage metrics. Specimens of sandwich structures made from skins of epoxy resin rein
