1. Three-dimensional reconstruction and intraoperative ultrasonography: Crucial tools to safely approach highly complex renal masses
ABSTRACT Purpose: Robot-assisted partial nephrectomy (RAPN) is rapidly increasing its role in the nephron-sparing surgery setting (1). The recent introduction of technological advancements is leading more experienced surgeons to approach complex renal mass with a conservative intent (2, 3). In particular, three-dimensional reconstruction and the use of intr

2. Ultrasound guided endoscopic combined Intrarenal surgery – 10 steps for the success
ABSTRACT Background: Endoscopic combined intrarenal surgery (ECIRS) has been used to treat complex kidney stones (1). The combined use of ultrasound (US) has the potential to improve safety and reduce radiation exposure, however, it is still underutilized (2). Objectives: Our objective is to describe, in a step-by-step manner, the ultrasound-guided ECIRS (

3. DEATH GAMES AND THE PERSISTENCE OF MEMORY: J. G. BALLARD’S WORLD WAR II FICTIONS
Abstract This article is a discussion of J. G. Ballard’s (semi-)autobiographical war narratives, with a focus on the different textual strategies and processes of signification Ballard employs from his avant-garde novel The Atrocity Exhibition (1970) to the feverish fictional account of his time in World War II China in “The Dead Time” (1977) and Empir

4. 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

5. Three-Dimensional Printing: is it useful for Cardiac Surgery?
Abstract Introduction: The medical use of three-dimensional (3-D) images has been a topic in the literature since 1988, but 95% of papers on 3-D printing were published in the last six years. The increase in publications is the result of advances in 3-D printing methods, as well as of the increasing availability of these machines in different hospitals. Thi

6. Discrimination of pores and cracks in iron ore pellets using deep learning neural networks
Abstract The discrimination between pores and cracks is an important step in the microstructural analysis of iron ore pellets. While the porosity is fundamental during the reduction process in blast furnaces, cracks are strongly detrimental to the mechanical strength. The usual image processing tools cannot automatically discriminate between these two types

7. IMAGENS QUE PRODUZEM CONHECIMENTOS: OBJETIVIDADE, INTERPRETAÇÃO OU DISPOSITIVOS DE CONSTRUÇÃO DE REALIDADES?
Resumo O presente artigo discute a relação entre imagem e realidade, tendo por base uma perspectiva psicossocial alinhada ao Construcionismo, voltada ao estudo da linguagem em ação. Seguindo a proposta de Peter Galison, abordamos três fases da relação entre imagem e realidade. A primeira tem por referência a aproximação da arte com a natureza; a se

8. Influence of doping with Sm3+ on photocatalytic reuse of ZnO thin films obtained by spin coating
ABSTRACT The difficulty in the powder reuse favors the study of materials in the form of thin films. ZnO based films have high photocatalytic potential. In this work, ZnO:xSm3+ (x = 0, 1, 2 and 4 %mol) thin films were prepared by spin coating method. The resins obtained to manufacture the thin films were prepared by complex polymerization method. The samples

9. Determination of the junction angle in fluvial channels from georeferenced aerial images from Google Earth Pro and UAV
Resumo Os ângulos de junção em canais fluviais são determinados a partir de complexos processos de erosão e deposição, resultantes da dinâmica do fluxo da vazão, da morfologia do leito e das margens, das feições hidrogeomorfológicas da bacia, de sua ordem e do uso e da ocupação do solo. Conhecer os valores desses ângulos é importante para mel

10. El análisis de imágenes como herramienta de monitoreo en la deshidratación de rodajas de banana
Abstract The objective of this work was to evaluate the morphometric, fractal and color changes during the dehydration of banana slices through the use of image analysis. The convective drying was performed between 75 °C and 134 °C at an air velocity of 0.65 m s-1. Results showed that the images provided quantitative information of the morphometric changes

12. Morphometric analysis in the shells of the planktonic foraminifera Orbulina universa: a source for paleoceanographic information?
Abstract In this study, we describe morphometric analyses of Orbulina universa morphotypes presently found in the Western South Atlantic, and their relation to the upper water thermohaline indexes. We also investigate this relationship under glacial and interglacial conditions between 7.2 and 32 kyr BP. Ten plankton samples distributed between 32º55' and 26
