13. The effect of nutritional scores on mortality in COVID-19 patients
SUMMARY OBJECTIVES: While studies on the treatment for the coronavirus disease 2019 (COVID-19) pandemic continue all over the world, factors that increase the risk of severe disease have also been the subject of research. Malnutrition has been considered an independent risk factor. Therefore, we aimed to investigate the clinical effect of dietary habits and

14. Electrochemical Determination of Trifluralin Herbicide Using Silver Solid Amalgam Electrode: Application in Fresh Food Samples
This paper reports the use of polished silver solid amalgam electrode (p-AgSAE) allied to square wave voltammetry (SWV) in the development of a simple, sensitive, fast and green electroanalytical methodology for the trifluralin herbicide determination in fresh food samples. The experimental (supporting electrolyte and potential and time accumulation) and vol

15. A Theoretical Antioxidant Mechanism for Cytoprotective Effect of p-Acetamide-Salicylate Derivatives against Free Radical Initiator AAPH in Human Erythrocytes
The molecular mechanism of cytoprotective effect on human erythrocytes of aminophenol and salicylates associated derivatives was related to their antioxidant capacity. The oxidative hemolysis induced by water-soluble free-radical initiator 2,2’-azobis-(2-amidine-propane)-dihydrochloride (AAPH) was inhibited by drug candidates named benzaminophen (BZL), sal

16. Clarifying the theoretical basis of the global geometric imperfection analysis (out-of-plumb columns)
Abstract The concrete structures present several geometric deviations, some of them considered indirectly in the safety factors of the design. However, the imperfections of the element axes, especially columns, should be explicitly considered in the structural analysis because they have great influence over the building stability. The NBR 6118:2014, Brazilia

17. SEWAGE PERFORMANCE OF A NEW TYPE OF FLAP FILTER
ABSTRACT The drainage performance of a mesh filter determines the water consumption degree of the filter and the efficiency of the next work cycle. Through analysis, we found that the influent flow rate and the sediment content of the influent were important influencing factors. This experiment focused on the drainage time, pressure difference, and cleanline

19. Analysis of the Resonator Element in Different Positions in the Circular Patch Microstrip Antenna
Abstract In this article, a circular patch microstrip antenna with a metamaterial resonator for 4G applications is proposed. For the design of the circular antenna patch, an approximate calculation was performed. The circular resonator is inserted into the patch for some antennas, in different positions for a parametric study. When incorporating the resonato

20. Can platelet-rich plasma coating improve polypropylene mesh integration? An immunohistochemical analysis in rabbits
ABSTRACT Purpose: Despite high success rates in the treatment of urinary incontinence, complications related to the use of polypropylene (PP) meshes are still a concern, especially in vaginal prolapses surgeries. The objective of this study was to assess the effect of autologous platelet-rich plasma (PRP) coating on the integration of PP meshes implanted in

23. DETERMINAÇÃO DE MERCÚRIO EM FÍGADO DE TETRÁPODES MARINHOS POR ESPECTROMETRIA DE FLUORESCÊNCIA ATÔMICA ACOPLADA A GERAÇÃO DE VAPOR FRIO (CV-AFS) E ESPECTROMETRIA DE MASSA COM FONTE DE PLASMA INDUTIVAMENTE ACOPLADO (ICP-MS): UMA COMPARAÇÃO SISTEMÁTICA ENTRE AS DUAS TÉCNICAS
This study compares the techniques cold vapour atomic fluorescence spectrometry (CV-AFS) and inductively coupled plasma mass spectrometry (ICP-MS) for the determination of Hg in biological samples (hepatic tissue from marine tetrapods). Acid digestions were performed for the samples and aliquots of them were analysed by ICP-MS and CV-AFS. To minimize the Hg

24. Flexible pavement overlay design of UFJF ring road based on the new Brazilian mechanistic-empirical pavement design method
Abstract The procedures for design and reinforcement projects regarding flexible pavements available in Brazil are mostly based on empirical models developed from studies carried out in specific localities, and therefore, should only be used in cases where equivalent climatic and traffic conditions are observed. The national highway agencies in partnership w
