1. Modified Ring Power Divider Using Stepped-Impedance Resonator
Abstract In this paper, the design of a modified ring power divider dedicated for wideband communication or measurement systems is presented. The proposed power divider is built by using a conventional ring power divider and an additional Stepped-Impedance Resonator (SIR). The even-odd mode analysis is used to derive the design equations. In order to observe

2. ABA regulation of post-germination desiccation tolerance in wheat cultivars contrasting in drought tolerance
ABSTRACT Post-germination desiccation tolerance (DT) was studied in two wheat cultivars. Effect of pretreatment of abscisic acid (ABA)/ osmotic/ salt/ heat stress was also studied. One day (d)-old seedlings of wheat cultivars PBW 644 (drought tolerant) and PBW 343 (drought susceptible) were exposed to ABA/stress treatment for next 1 d, desiccated for 4 d and

3. Surface Imprinting of Silica Gel by Methyldopa and Its Application in the Solid Phase Extraction Procedure
An imprinted amino-functionalized silica gel material was prepared by surface molecular imprinting technique combined with a sol-gel process on the supporter of activated silica gel and used as a solid-phase extraction for the extraction and determination of methyldopa (MTD). Non-imprinted silica adsorbent was synthesized without the addition of MTD using th

4. Increasing the regional availability of the Standardized Precipitation Index: an operational approach
ABSTRACT The need to use a length of rainfall records of at least 30 years to calculate the Standardized Precipitation Index (SPI) limits its application in several Drought Early Warning Systems of developing countries. Therefore, in order to increase the number of weather stations in which the SPI may be applied, this study quantified the difference among S

5. Effects of direct and alternating current on the treatment of oily water in an electroflocculation process
In the direct current mode (DC), widely used in electroflocculation (EC), the formation of an impermeable oxide layer on the cathode causes the declining of the efficiency of this process. This disadvantage has been reduced by adopting alternating current (AC). In this study, the effects of AC and DC on operational parameters such as the removal of oils and

6. Verificação da previsão do tempo em São Paulo com o modelo operacional WRF / Review of weather in São Paulo with the WRF Operational Model.
Forecasts of daily maximum and minimum temperatures and rainfall performed by the operational numerical weather prediction WRF (Weather Research Forecasting) model in the São Paulo are evaluated. Initial and boundary conditions provided by the 00UTC Global Forecast System (GFS) Model and WRF run for 72 hours, with two nested grids (with horizontal grid spac

7. Estudo da internalização do conhecimento por meio do uso de sistemas de informações gerenciais hospitalares em João Pessoa - PB.
Hospitals are organizations where information is particularly important where much of the work of health professionals is related to the manipulation of information, where reliability, availability and data integrity will contribute to the quality of patient care and better management of the hospital. Thus, this study analyzes the process of internalization

8. Análise da cinemática dos compartimentos da parede torácica nas posições supino e sentada de pacientes com esclerose lateral amiotrófica
Amyotrophic Lateral Sclerosis (ALS) is characterized by deterioration of upper and lower motor neurons. The main components, which alter the respiratory muscles are the inspiratory, expiratory, and bulbar, leading to chronic respiratory failure. One way to improve gas exchange of these individuals is by employing non-invasive ventilation (NIV). Therefore, th

9. A regulação da atividade de trabalho na produção enxuta
The use of lean manufacturing principles and techniques has been increasing considerably in companies over the past couple of decades. The employment of such techniques prompts profound transformations on both the project and work organization of the company that chooses to employ them. By this approach, companies that embrace the lean manufacturing model ga
