26. Steel desulfurization on RH degasser: physical and mathematical modeling
Abstract Due to the high-quality steel demand, especially for ultra-low Sulfur steel, RH desulfurization has been practiced. Based on this, mathematical and physical modeling have been applied to study steel desulfurization by reagent addition in the RH degasser vacuum chamber. The main result of cold modeling, using water and oil emulating steel and slag, r

27. High Residual Gradient Following a Self-Expandable Transcatheter Aortic Valve-in-Valve Implantation — Risk Factor Analysis, Outcomes, and Survival
Abstract Introduction: Transcatheter aortic valve-in-valve implantation (TAVI-ViV) can be associated with unfavorable hemodynamic outcomes. This study aimed to estimate the prevalence, identify the risk factors, and evaluate the outcomes and survival of patients with high residual gradients after TAVI-ViV. Methods: A total of 85 patients were included in t

28. A Novel In Silico Monte Carlo Approach to Optimize a PSD Estimation Problem. Generation of Data Fusion Experiment Rules
ABSTRACT This article analyzes the performance of combining information from Scanning Electron Microscopy (SEM) micrographs with Static Light Scattering (SLS) measurements for retrieving the so-called Particle Size Distribution (PSD) in terms of experimental features. The corresponding data fusion is implemented using a novel Monte Carlo-based method consist

30. Postharvest ascorbic acid application maintained physiological and antioxidant responses of Guava (Psidium guajava L.) at ambient storage
Abstract Guava (Psidium guajava) is a highly perishable fruit with a short shelf life as physico-chemical changes occur continuously and rapidly after harvest leading to heavy postharvest losses. This experiment was laid down to unravel the effects of ascorbic acid (AA) on ripened guava fruits to improve its shelf life and quality. Four different concentrati

31. Alterações hormonais endógenas em resposta à aplicação exógena de 6-benzilaminopurina em pré- e pós-colheita de hastes florais de lírio
Resumo Os fitormônios desempenham um papel fundamental na regulação das respostas das plantas ao estresse. As citocinas são um tipo de fitormônios envolvidos na regulação de muitos processos biológicos importantes relacionados ao crescimento, desenvolvimento e resposta a variáveis ambientais. A aplicação exógena de citocinas aumenta a possibilida

34. Implications of global climate change for the development and ecological interactions between two key Amazonian aquatic macrophytes
ABSTRACT Amazon wetlands are among the most vulnerable ecosystem to be impacted by climate change, which may increase the frequency of extreme droughts and floods. We used Eichhornia crassipes and Pistia stratiotes, two abundant aquatic plants in the Amazon floodplains, to evaluate the effects of combined temperature and [CO2] increase on growth, physiology

36. Associação de Injúria Miocárdica e Mortalidade em Pacientes Hospitalizados com COVID-19
Abstract Cardiac arrhythmias and requirement for permanent pacemaker (PPM) post open-heart surgery are some of the complications that can contribute to significant morbidities postoperatively and delay in normal recovery if not treated promptly. The reported rate of a PPM following isolated, elective coronary artery bypass grafting is < 1%, while following a
