1. Microstrip 3-Bit Fractal-based Phase Shifter
Abstract This paper presents the implementation of a 3-bit microstrip fractal-based phase shifter operating in the 430 MHz to 470 MHz frequency range. The fractal structure is used to confine different delay line lengths in the same area due to the space-filling properties of the used Hilbert fractal curve. The proposed design has three bits corresponding to

2. Source-sink relationships in two soybean cultivars with indeterminate growth under water deficit
Abstract Water deficit is a major factor limiting crop yield in rainfed areas. We hypothesized that under water deficit the decrease of photosynthetic production stimulates: carbohydrate remobilization from leaves, stems and roots to reproductive organs; and decreasing flowering intensity and pod development. The present work aims to study the effect of wate

3. Urethral pressure variation: a neglected contributing factor in patients with overactive bladder syndrome?
ABSTRACT Objective To study urethral pressure variations during the whole filling phase among different groups of patients. Material and Methods We investigated 79 consecutive patients from January 2011 to June 2012. All patients were recruited within our routine practice in our continence clinic and were evaluated with urodynamic exam according to the s

4. Preparation of an Injectable Macroporous α-TCP Cement
Abstract One of the most important characteristics of calcium phosphate cements is their resorbability when implanted in the body. However, the in vivo resorption rate is slow due to the lack of intrinsic open porosity. In this study, macroporous structures were obtained by mixing alpha-tricalcium phosphate (α-TCP) cement with a foamed liquid phase containi

5. Microstructural Evolution and Mechanical Properties in Directionally Solidified Sn–10.2 Sb Peritectic Alloy at a Constant Temperature Gradient
The Sn–10.2 Sb (mass fraction) peritectic alloy was prepared using a vacuum melting furnace and a hot filling furnace. The samples were directionally solidified upwards at steady state conditions with a constant temperature gradient (G=4.5±0.2 K. mm-1) under different growth velocities (V=13.3–266.7 µm. s-1) in a Bridgman-type directional solidificatio

6. CONSTRUÇÃO DE UM DISPOSITIVO DE PRESSURIZAÇÃO A VÁCUO PARA A PREPARAÇÃO DE FASES ESTACIONÁRIAS MONOLÍTICAS VIA PROCESSO SOL-GEL
The filling of capillaries via the sol-gel process is growing. Therefore, this technical note focuses on disseminating knowledge acquired in the Group of Analytical Chemistry and Chemometrics over seven years working with monolithic stationary phase preparation in fused silica capillaries. We believe that the detailed information presented in this technical

7. The influence of the area of the Serra da Mesa Hydroelectric Plant, State of Goiás, on the frequency and diversity of anophelines (Diptera: Culicidae): a study on the effect of a reservoir
INTRODUCTION: Bioecological aspects of anophelines (Diptera: Culicidae) near areas under the direct influence of the hydroelectric plant reservoir of Serra da Mesa in Goiás, Brazil, were analyzed. METHODS: Samples were collected at the surrounding dam area during the phases before and after reservoir impoundment. The influence of climatic and environmental

8. Análise fotoelástica da tensão de contração da polimerização de compósitos resinosos sob influência de técnicas restauradoras / Photoelastic analysis of polymerization shrinkage stress of composites under the influence of restorative techniques
Polymerization shrinkage stress is an undesirable and inevitable characteristic of adhesive restorations. It is important to understand the stress distribution to improve the clinical effectiveness of resin composite restoration. Chapter 1: The aim was to evaluate the polymerization shrinkage stress and degree of conversion of a resin composite material subm

9. Sistema de irrigação por capilaridade na produção de porta-enxertos de mudas citricas na fase de sementeira / Irrigation system by capillary action in the citrus rootstocks production in seedings stage
The water and nutrition management in the production of citrus rootstocks in the seedling phase performed by sprinkler systems, manually operated, presents the environmental outcome of water or residual solution disposal from the fertigation. The generated wastewater is generally discarded directly in the soil with the risk to reach the groundwater and conta

10. Effects of Ag addition on some physical properties of granular YBa2Cu3O7-δ superconductor
The effects of Ag addition on some physical properties of YBa2Cu3O7-δ superconductor has been studied. The samples were produced by different routes and characterized by scanning electron microscopy, differential thermal analysis, thermogravimetric analysis, X-ray diffraction and nanoindentation. The superconducting properties were studied by dc magnetizati

11. IV.Heat stress in Triticum: kinetics of Fe and Mn accumulation
The interactions between Fe/Mn accumulation and the photosynthetic light reactions were investigated in heat stressed bread and durum wheat genotypes (Triticum aestivum L. and Triticum turgidum subsp.durum). Four genotypes were chosen according to its genetic background diversity. Plants were grown in a greenhouse at two different day/night temperatures regi

12. Development of an incident investigation guide for healthcare environments based on the project management structure / Desenvolvimento de um guia para investigação de incidentes em ambientes de saude baseado na estrutura de gerenciamento de projetos
The hazards inside a healthcare institution are increased by the growth in the use of more technological equipments. Consequently, risk management measures must be taken to ensure both a safe workplace and an improved safety for the patients, family and visitors that transit daily by these institutions. One possible risk management measure is the incident in
