2. Surgical Reconstruction of a Left Ventricular Aneurysm Using an Extracellular Matrix Patch
Abstract The left ventricular aneurysm is a pathological condition defined as an akinetic or dyskinetic area of the left ventricle (LV) wall associated with reduced ejection fraction. The most common surgical technique to reconstruct a left ventricular aneurysm is endoventricular patch plasty (Dor procedure). In this case, endoventricular reconstruction of t

3. Influence of shadowing in Sequoia sempervirens (D. Don) Endl. mini-stumps and mini-cuttings
ABSTRACT The aim of the work was to analyze the influence of variables such as shading, temperature and humidity in the production and rooting of mini-cuttings of Sequoia sempervirens (D. Dom) Endl. in a clonal mini-garden. The experiment was conducted at the Forest Nursery at the University of Santa Catarina State - CAV/UDESC, Lages - SC. The minicuttings w

4. Robot-assisted vesico-vaginal fistula repair: technical nuances
ABSTRACT Introduction: Vesico-vaginal fistula (VVF) is a rare event in Western countries and are mainly consequent to iatrogenic injuries (1, 2). When conservative management fails, surgical repair is needed, although timing and surgical approach (open or minimally invasive (3)) are still controversial (4, 5). Herein we present a step-by-step description of

6. Aqueous Extract of Cumaru (Dipteryx odorata) Seeds as Corrosion Inhibitor for Mild Steel in Hydrochloric Acid Solution
The corrosion inhibition of mild steel by aqueous extract of cumaru (Dipteryx odorata) seeds and its high molecular weight fraction (HMWF) was investigated in 1 mol L-1 HCl solution. The study was carried out through gravimetric essays, open circuit potential measurements, anodic and cathodic polarization curves and electrochemical impedance analyses, as wel

7. Heterostructured Langmuir-Blodgett Films of Ruthenium Bipyridine with 1,3,4-Naphthooxadiazole-Derived Amphiphile Complex as a Charge Storage Electrode
The molecular control in Langmuir-Blodgett (LB) films may be exploited in charge storage electrodes provided a suitable choice of molecular architecture and components is made. In this paper, we employed a naphtyl-1,3,4-oxadiazole amphiphile (NFT1) and its complex [Ru(bpy)2NFT1]PF6 (RuNFT1) (bpy = 2,2’-bipyridine) in heterostructured LB films in a proof-of

8. Double Layer Frequency Selective Surface for Ultra Wide Band Applications with Angular Stability and Polarization Independence
Abstract In this paper, a double layer stopband Frequency Selective Surface (FSS) for Ultra-Wide Band (UWB) applications is presented. The proposed FSS consists of two cascaded conventional FSS, one with double square loops and other with square loops. The − 10dB frequency band from 3.00 GHz to 11.64 GHz is achieved, with a fractional bandwidth of 149 %. E

9. Design and evaluation of rhubarb total free anthraquinones oral colon-specific drug delivery granules to improve the purgative effect
Rhubarb is commonly used as a cathartic in Asian countries. However, researchers have devotedextensive concerns to the quality control and safety of rhubarb and traditional Chinese preparations composed of rhubarb due to the instable purgative effect and potential nephrotoxicity of anthraquinones. In this study, we aimed to prepare rhubarb total free anthraq

11. Escolha das Energias de Soldagem para Aplicação na Técnica da Dupla Camada na Soldagem do Aço ASTM 131 Grau AH 36
Resumo Durante o processo de soldagem o aço microligado ASTM A131 Grau AH36 pode apresentar defeitos oriundos dos ciclos térmicos (distorções) que demandarão procedimentos onerosos como o tratamento térmico pós-soldagem. Somando-se a isto, este aço não é indicado a sofrer normalização, normalização seguida por revenimento, ou por têmpera e rev

12. An Amorphous Silicon Photo TFT with Si3N4/Al2O3 or HfO2 Double Layered Insulator for Digital Imaging Applications
Abstract This paper focuses on amorphous silicon photo thin-film transistors with double layered insulator using Si3N4/Al2O3 or HfO2 as candidates for the succession of Si3N4 as a traditional insulator in the fabrication of hydrogenated amorphous silicon thin-film transistors. Whether for industry or for research, there is a need to investigate the use of th
