13. A Parametric Study of Inductive SWIPT Systems Assisted by Metamaterial Using Virtual Magnetic TL-Based Channel Modeling
Abstract This paper presents a general methodology based on the description of the inductive channel as virtual magnetic transmission-lines (VMGTLs). In comparison with other existing methods, VMGTL approach presents a better physical insight of the channel behavior since the model correctly preserves the energy flow between the transmitting and receiving co

14. INSIGHT INTO THE CONFORMATIONAL SPACE OF N-BENZYL-N-(FURAN-2-YLMETHYL)ACETAMIDE BY NMR SPECTROSCOPY AND DFT CALCULATIONS
In this study, the conformational behavior of N-benzyl-N-(furan-2-ylmethyl) acetamide in chloroform was addressed by using a combined experimental/theoretical strategy using NMR spectroscopy and quantum chemical calculations. The 1H and 13C one-dimensional NMR spectra, as well as the two-dimensional HSQC-DEPT and HMBC-DEPT NMR spectra, evinced the presence o

15. Where’s the Spin? A DFT Study of Mixed-Valence Cyanide-Bridged Ruthenium Polypyridines
This article discusses the use of density functional theory (DFT) calculations in classifying and characterizing bimetallic ruthenium mixed-valence systems in terms of their electronic localization/delocalization degree. A standard B3LYP/LanL2DZ methodology including integral equation formalism-polarizable continuum model (IEF-PCM) solvent model is evaluated

17. Determining the true incidence of acute transfusion reactions: Active surveillance at a specialized liver center
ABSTRACT Background: Blood transfusion is a life-saving procedure, but may cause adverse transfusion reactions (TRs). The reporting of TRs is often missed due to various reasons. The aim of this study was to determine the incidence of unreported acute TRs through active surveillance and to compare it with the incidence of passively reported TRs. Methods: T

18. INSIGHT INTO THE EFFECTS OF BAY-SUBSTITUENTS ON STABLE PERYLENE DIIMIDE RADICAL ANION SALTS
In previous work, the facile method to prepare perylene diimide radical anion salt by alkali treatment was reported. However, the effects of structure on synthetic process of perylene diimide radical anion salt, and the difference of response to Cu 2+ are not thoroughly understood. In this work, two bay-substituted perylene diimide derivatives radical anion

19. Fruits of neotropical species of the tribe Malveae (Malvoideae - Malvaceae): macro- and micromorphology
ABSTRACT Fruit morphology of the tribe Malveae has been discussed since the first taxonomic classifications of Malvaceae. The fruits are schizocarps, with some genera possessing an endoglossum. Besides morphological variation in the endoglossum, other differences include the number seeds per locule and ornamentation of the exocarp. An in-depth study of the f

20. Atividade antibacteriana de nanopartículas de polipirrol diante de Staphylococcus aureus isolados de amostras de leite de vacas e cabras com mastite
ABSTRACT The aim of the present study was to evaluate the antibacterial behavior of polypyrrole nanoparticles (PPy-NPs) in water against biofilm producer or not S. aureus isolated from cows and goats with mastitis. One hundred and thirty-eight isolates of S. aureus were initially evaluated for biofilm formation by spectrophotometry in microplates. In additi

21. PRELIMINARY ASSESSMENT OF THE PROCESSING OF HIGH-ACIDITY FATTY MATERIALS USING SOLID CATALYSTS FOR THE OBTAINMENT OF FATTY ACID METHYL ESTERS
Abstract This work presents the processing of a high-acidity oil through sequential reactions of esterification using montmorillonite K10 and transesterification using zinc monoglycerolate. Since these solids had not been employed along with this approach beforehand, the objective of this work is to provide a general insight of the proposed process and demon

22. Comparative bio-efficacy of nuclear polyhedrosis virus (NPV) and Spinosad against American bollwormm, Helicoverpa armigera (Hubner)
ABSTRACT American bollworm (ABW), Helicoverpa armigera (Hubner), is considered as a major pest of cotton, Gossypium hirsutum, all over the globe. Due to its destructive feeding nature and continuous consumption of the same chemicals, it devolved resistant against many insecticides. Therefore, a combined application of bio- and synthetic-pesticide need to eva

23. Social Accountability of Medical Schools and Social Representations of Medical Students in the Context of the More Doctors Program
RESUMO Diversos debates, no contexto nacional e internacional, têm sugerido a necessidade de mudanças na formação médica, de modo que ela esteja em consonância com a organização dos sistemas de saúde. Nessa perspectiva, propõe-se que as escolas sejam orientadas pela responsabilidade social, que consiste em ordenar o ensino, a pesquisa e as atividad

24. As regras da subversão: Roberto Schwarz, Bertha Dunkel e a revista Teoria e Prática
RESUMO O artigo trata do “Grupo 2 do Seminário sobre O Capital de Marx”, promovido por Roberto Schwarz e Ruy Fausto em 1963, assim como de sua transformação na revista Teoria e Prática. Trata-se de estabelecer os nexos entre a morfologia e a produção intelectual dos membros participantes. Considerando o perfil e as posições institucionais dos “
