13. COVID-19: Priority Use of N95 Mask or Double Mask
Abstract Introduction Hashimoto thyroiditis (HT) shares many characteristics with papillary thyroid carcinoma (PTC), and some studies show that, when associated, PTC is diagnosed mostly with smaller lesions and multifocal pattern. Objective To evaluate the relationship between HT and PTC. Methods A retrospective study of 155 patients who underwent total t

14. Single-Layered Paper-Based Microfluidic Devices Made by Paint-Spraying Technique with Great Barrier Resistance for Colorimetric Assays
The single-layered paint-spraying paper based microfluidic devices (sp-μPADs) have been for the first time integrated with the colorimetric assay. The polymethyl methacrylate (PMMA) board was applied as the mask instead of the iron mask, reducing the power requirement of the cutting machine. The paint was sprayed into the paper, which blocked the pores of t

16. Why We Need to Use and which Mask Types are Effective against the Novel Coronavirus (COVID-19)?
Multicomponent reactions are attractive for the development of bioactive substances, being a one-pot synthesis allows a quick and efficient synthesis, and allows the construction of a diversity of privileged structures. The Debus-Radziszewski reaction, a classic example of a multicomponent reaction for obtaining 2,4,5-tri-substituted imidazole, was used to c

17. PROCESSING OF A METAL CONCENTRATE FROM GROUND WASTE PRINTED CIRCUIT BOARDS IN ACIDIC MEDIA USING HYDROGEN PEROXIDE AS OXIDANT
The recovery of precious and base metals of a metal concentrate from ground waste printed circuit boards (PCBs) is described in detail. Samples were treated with NaOHaq. to remove the soldering mask. Experiments were performed in acidic medium (HF, H2SO4, CH3COOH or H3PO4) using H2O2 as oxidant. Base metals were leached in high yields (>99 wt.%) at ~40 ºC a

18. Sixteenth-Mode Substrate-Integrated-Waveguide (SMSIW) Resonator for Dielectric Characterization of Liquid Mixtures
Abstract In this work, a new concept of planar resonator technique for measurement of liquid mixture permittivity is proposed, designed, and implemented using a Sixteen-Mode Substrate Integrated Waveguide (SMSIW) technology. To design the proposed sensor, the conventional SMSIW resonator is designed with an additional air hole on the open side, and then we a

19. Feasibility of non-intubated anesthesia and regional block for thoracoscopic surgery under spontaneous respiration: a prospective cohort study
Data about the feasibility and safety of thoracoscopic surgery under non-intubated anesthesia and regional block are limited. In this prospective study, 57 consecutive patients scheduled for thoracoscopic surgery were enrolled. Patients were sedated with dexmedetomidine and anesthetized with propofol and remifentanil. Ropivacaine was used for intercostal ner

20. Direct Analysis of Human Hair Before and After Cosmetic Modification Using a Recent Data Fusion Method
The cosmetic modification of hair is a very common procedure used to mask or cover evidence at a crime scene. Deoxyribonucleic acid (DNA) tests are expensive and require good-quality collection of samples and a database profile. To overcome these challenges, direct analysis was performed on a large set of hair strands collected from individuals, denoted orig

21. A RELAÇÃO INTRÍNSECA ENTRE A PSICOLOGIA HISTÓRICO-CULTURAL E A EPISTEMOLOGIA MARXIANA
RESUMO. Considerando as investidas ideológicas que tencionam mascarar as bases epistemológicas marxistas da psicologia histórico-cultural, o artigo em tela visa contribuir para evidenciar o modo como o materialismo histórico e dialético edificou os pressupostos essenciais desta teoria psicológica. Para tanto, estabeleceu-se a proposição de que os tr�

22. Endovascular repair of subclavian artery injury secondary to internal jugular vein catheterization: case report
Resumo Justificativa e objetivos A cateterização da veia jugular interna guiada por ultrassom é um procedimento comum e geralmente seguro em sala cirúrgica. No entanto, a punção inadvertida de uma artéria não compressível, como a artéria subclávia, embora rara, pode estar associada a sequelas e risco para vida, incluindo hemomediastino, hemotóra
