13. Revascularização ilíaco-femoral alternativa em doença oclusiva aortoilíaca extensa
Resumo Nas últimas décadas, observou-se o aumento expressivo do tratamento endovascular para a doença oclusiva aortoilíaca. Muitos benefícios foram demonstrados, principalmente nas lesões arteriais não complexas do eixo ilíaco; porém, ainda existe dificuldade na obtenção de resultados adequados a médio e longo prazo quando falamos de doenças ocl

15. Structural differences in mammal assemblages between savanna ecosystems of the Colombian Llanos
Abstract The Colombian Orinoquia region is characterized by a high diversity of mammals, which is associated with complex ecosystems that include large extensions of Neotropical savannas (known locally as “Llanos Orientales”). Despite accelerated anthropogenic transformations in savanna ecosystems, the knowledge to design effective conservation strategie

16. IMPACT OF A SIMULATED LAPAROSCOPIC TRAINING PROGRAM IN A THREE-YEAR GENERAL SURGERY RESIDENCY
RESUMO Racional: Residência em Cirurgia Geral pode durar entre 2-6 anos, dependendo do país. Residência mais curta deve otimizar a exposição dos residentes às cirurgias. Sabe-se que o treinamento cirúrgico simulado encurta as curvas de aprendizado, mas a informação relacionada à como isso afeta a residência em relação à exposição clínica �

17. Increase in the diagnosis of mycobacteremia after the implementation of semi-automated blood culture at a Brazilian public health laboratory
Abstract INTRODUCTION The prevalence of hematogenous dissemination of mycobacteria is high in immunosuppressed patients. The isolation of mycobacteria in culture remains the standard procedure. METHODS This is a cross-sectional study based on the results of solid (Löwenstein-Jensen medium) and semi-automated liquid (BACTEC 9240) blood cultures, obtained

18. Reappraisal of the Sumé Complex: geochemistry and geochronology of metaigneous rocks and implications for Paleoproteorozoic subduction-accretion events in the Borborema Province, NE Brazil
Abstract The Alto Moxotó Terrane represents the largest exposure of Paleoproterozoic rocks in the central Borborema Province. Several medium- to high-grade metamorphic units are described in the terrane, however geochronological data are still scarce, and the main periods of crust build-up and recycling are poorly known. In this study, we investigate the na

19. Investigation on Ruthenium(II) Bipyridine/AgIII Complexes Chemiluminescence System and Its Application for Sensitive Norfloxacin and Ofloxacin Detection
The reaction mechanism of AgIII complex ([Ag(HIO6)2]5–) with ruthenium(II) bipyridine (Ru(bpy)32+) in acid medium was investigated. A novel flow injection chemiluminescence (CL) analysis method was developed for the detection of norfloxacin (NFLX) and ofloxacin (OFLX) in commercial drug, milk and human urine samples based on AgIII-ruthenium(II) bipyridine

20. Seed germination and development of orchid seedlings (Cyrtopodium saintlegerianum) with fungi
Resumo Fungos do complexo Rhizoctonia são micorrízicos de orquídeas e podem germinar suas sementes e desenvolver as plântulas. Neste contexto, nosso objetivo foi selecionar um isolado fúngico para promover a germinação e o desenvolvimento de plântulas de Cyrtopodium saintlegerianum. Foram encontrados pelotons nas raízes desta orquídea e foram ident

22. Experimental and Theoretical Study of Corrosion Inhibition of Mild Steel in 1.0 M HCl Medium by 2(-4( hloro phenyl-1H- benzo[d]imidazol)-1-yl)phenyl)methanone
The 2(-4(chloro phenyl-1H- benzo[d]imidazol)-1-yl)phenyl)methanone (CBIPM) was synthesized and tested as a corrosion inhibitor for mild steel in 1.0 M HCl solution using electrochemical and spectroscopy measurements. Results obtained showed that this compound has a good inhibition properties for mild steel corrosion in acidic medium which its inhibition effi

23. Chitosan and gum arabic nanoparticles for heavy metal adsorption
Abstract Chitosan (CT) is a polysaccharide with the ability to adsorb metals on its surface. In this work, CT-based nanoparticles (NPs) are produced by complex formation with gum arabic (GA) to increase their adsorbent potential for removal of heavy metals in aqueous medium. Adsorption efficiency is evaluated as a function of NP composition and polysaccharid

24. A direct technique for the homogenization of periodic beam-like structures by transfer matrix eigen-analysis
Abstract To homogenize lattice beam-like structures, a direct approach based on the matrix eigen- and principal vectors of the state transfer matrix is proposed and discussed. The Timoshenko couple-stress beam is the equivalent continuum medium adopted in the homogenization process. The girders unit cell transmits two kinds of bending moments: the first is g
