1. A High-Selectivity Bandpass Filter Using Dual-Mode Coupling Resonator
Abstract In this work, a new model of high selectivity dual-mode bandpass filter is presented. The proposed filter consists of a set of coupled lines with a dual-mode adjustable response in its design process. An improvement in selectivity is presented by combining the dual-mode element with a classic band rejection structure, thus making it possible to intr

2. Simple Spectrophotometric Determination of Iron in Diesel Oil after Sample Preparation Employing Extraction Induced by Emulsion Breaking
This work reports the development of a simple and fast method for the spectrophotometric determination of Fe in diesel oil using the classic reaction with 1,10-phenanthroline after its extraction induced by emulsion breaking (EIEB). The extraction parameters of EIEB were optimized (concentration of HNO3 and Triton X-100® in the emulsifying solution) as well

3. TITULADOR AUTOMÁTICO EM FLUXO-BATELADA UTILIZANDO UM HARDWARE DE CÓDIGO FONTE ABERTO ARDUINO
This work describes the development of an automatic titrometric method in flow-batch with potentiometric detection using alternative and easily accessible materials. Arduino board and its modules, solenoid valves to control the flow rate, peristaltic pump to propel and suction fluids and tubes of inert material to connect the different parts of the Flow-Batc

4. A Novel Tri-bandpass Filter Side-coupled Square Ring Based
Abstract This work presents the design of a tri-bandpass filter based on the side-coupled square ring structure. The modeling is conceived from the classic approach of coupled transmission lines. The geometry consists of a square structure of electrical length equal to twice the wavelength of the main operating frequency, and the laterally coupled lines thro

5. Neuroimaging of intrinsic connectivity networks: a robust method for assessing functional brain organization in psychiatric disorders
Objective: German psychiatrist Kurt Schneider proposed the concept of first-rank symptoms (FRS) of schizophrenia in 1959. However, their relevance for diagnosis and prediction of treatment response are still unclear. Most studies have investigated FRS in chronic or medicated patients. The present study sought to evaluate whether FRS predict remission, respo

6. Schneider’s first-rank symptoms as predictors of remission in antipsychotic-naive first-episode psychosis
Objective: German psychiatrist Kurt Schneider proposed the concept of first-rank symptoms (FRS) of schizophrenia in 1959. However, their relevance for diagnosis and prediction of treatment response are still unclear. Most studies have investigated FRS in chronic or medicated patients. The present study sought to evaluate whether FRS predict remission, respo

7. A RENEWABLE CATALYST FOR A RENEWABLE CHEMICAL: GRAM-SCALE CONVERSION OF FURFURAL TO FURFURYL ALCOHOL BY THE CARROT (Daucus carota)
The bioconversion of furfural to furfuryl alcohol using only carrot bits in water at room temperature and ambient pressure is presented. This reaction led to the bioreduction of furfural with 99% conversion and 99% selectivity to an alcohol. This simple and “fully” green process may represent an alternative to classic hydrogenation processes. Also, witho

8. Epidemiological, clinical, and laboratory aspects in a case series of canine hyperadrenocorticism: 115 cases (2010-2014)
RESUMO: A caracterização clínica-epidemiológica de doenças auxilia no direcionamento do diagnóstico. O objetivo deste trabalho foi descrever aspectos epidemiológicos, clínicos e laboratoriais de uma série de casos de hiperadrenocorticismo (HAC) canino. Foram avaliados 115 prontuários de cães diagnosticados pelo teste de supressão por baixa dose d

9. Precarização do trabalho e sofrimento psíquico: ação em psicodinâmica do trabalho em um serviço de farmácia hospitalar universitário
Resumo Introdução: desde 2014, a divisão de farmácia (DF) de um hospital universitário vivencia um processo de precarização do trabalho derivado de uma crise político-financeira. Visando superar conflitos decorrentes dessa precarização, os farmacêuticos demandaram uma ação em psicodinâmica do trabalho (PDT) a uma equipe de pesquisadores da un

10. Nonlinear static analysis of a pile-supported wharf
Resumo O objetivo deste artigo é desenvolver uma análise estática não-linear através de um estudo de caso de um cais sobre estacas situado em uma nova área portuária para petroleiras. A atividade sísmica da área é muito intensa com uma aceleração máxima do solo de 0.55 g. Por esta razão, é muito importante analisar o comportamento estrutural n

11. Variaciones Greenberg: apogeo y debacle de un crítico de arte
Abstract: Starting from the classic text Avant-garde and kitsch, we propose to analyze the work of the North American critic Clement Greenberg. After the US state intervention in the arts between 1935 and 1943 (the WTA), Clement Greenberg emerged as one of the main critics who sought to unify the “high art” of that country. The critic attempted to justif
