13. A obsessão das ideias ou a literatura que fracassa: uma abordagem a partir de Marilene Felinto
Resumo Este artigo se utiliza da obra de Marilene Felinto para refletir sobre uma obsessão das ideias no campo literário, traçando, para tanto, uma linha entre o seu romance de estreia As mulheres de Tijucopapo (1982) e sua última publicação até o momento, a novela Obsceno abandono: amor e perda (2002). Esclarecida a obsessão em reincidências que pr

14. Medicine, torture, the death penalty and the democratic state: from collaboration to emancipation
Resumo Abusos médicos têm ocorrido nas últimas décadas no contexto da tortura e da pena de morte. Violações graves e totalmente inaceitáveis de ética médica e dos direitos humanos ocorreram em instituições que cuidam de pessoas vulneráveis. E, no entanto, ainda há uma necessidade de tornar visível todo o espectro de violência e violações dos

15. Study on Preparation and Performance of High Swelling Bentonite
ABSTRACT For improving the expansibility of natural Ca-based bentonite (Ca-Bent), the Ca-Bent was modified with sodium dodecyl benzene sulfonate(SDBS)-Na2CO3 complex agent by microwave semi-dry method. And the ratio of Na2CO3 to SDBS, microwave power, radiation time and initial temperature on the modification were studied. Furthermore, X-ray diffraction (XRD

16. Effective Synthesis of Silicon Carbide Nanotubes by Microwave Heating of Blended Silicon Dioxide and Multi-Walled Carbon Nanotube
Silicon carbide nanotube (SiCNTs) has been proven as a suitable material for wide applications in high power, elevated temperature and harsh environment. For the first time, we reported in this article an effective synthesis of SiCNTs by microwave heating of SiO2 and MWCNTs in molar ratio of 1:1, 1:3, 1:5 and 1:7. Blend of SiO2 and MWCNTs in the molar ratio

17. A simple strategy to design broadband low power consumption distributed Raman amplifier
Abstract In this work, a simple strategy to design wideband low power consumption Raman amplifiers is demonstrated for a three-pump configuration using a low water peak optical fiber. The approach is based on the introduction of a novel numerical measure, which quantifies and isolates pump-pump interaction contribution to gain profile and analyzes its correl

18. Construction and measurement of an electromagnetic noise generator based on an automotive coil
This article covers the design of an electromagnetic noise generator which uses an automotive coil as the main component. A short theoretical analysis covers the generation of high voltage pulsed current from the available DC source originated from the battery. An electronic dimmer, a circuit used to control the brightness of a light, by controlling the effe

19. Comparison of In-Flight Measured and Computed Aeroelastic Damping: Modal Identification Procedures and Modeling Approaches
ABSTRACT The Operational Modal Analysis technique is a methodology very often applied for the identification of dynamic systems when the input signal is unknown. The applied methodology is based on a technique to estimate the Frequency Response Functions and extract the modal parameters using only the structural dynamic response data, without assuming the kn

20. Molecular characterization of multidrug-resistant
Klebsiella pneumoniae isolatesKlebsiella pneumoniae is an important cause of healthcare-associated infections worldwide. Selective pressure, the extensive use of antibiotics, and the conjugational transmission of antibiotic resistance genes across bacterial species and genera facilitate the emergence of multidrug-resistant (MDR)K. pneumoniae .

21. Long-term correlation of the electrocorticogram as a bioindicator of brain exposure to ionizing radiation
Understanding the effects of radiation and its possible influence on the nervous system are of great clinical interest. However, there have been few electrophysiological studies on brain activity after exposure to ionizing radiation (IR). A new methodological approach regarding the assessment of the possible effects of IR on brain activity is the use of line

22. Experimental-based subsystem models for simulation of heterogeneous optical networks
This work presents and analyzes experimental-based subsystem models for Erbium doped fiber amplifiers (EDFAs) and wavelength selective switches (WSSs) under operation in a metropolitan optical network testbed. Firstly, the performance of the EDFAs and two gain control types are analyzed in a heterogeneous experimental setup with lightpaths modulated at 10G/1

24. Impacted Anterior Urethral Calculus Complicated by a Stone-containing Diverticulum in an Elderly Man: Outcome of Transurethral Lithotripsy without Resection of the Diverticulum
Introduction The prevalence of lower urinary tract symptoms (LUTS) is about 20% in men aged 40 or above. Other than benign prostatic hyperplasia (BPH), urethral diverticulum or calculus is not uncommon for LUTS in men. Surgical treatment is often recommended for urethral diverticulum or calculus, but treatment for an impacted urethral calculus complicated b
