摘要： Due to rapid developments in computer technologies over the last two decades, computer-based process modeling has become an important tool for the improvement of existing process technologies and the development of innovative ones. With the help of numerical process simulations [1], complex and costly experimental trials can now be reduced to a minimum. In particular, for metallurgical processes, computer simulations are of outstanding *** et al. [Contribution 1] provided an article entitled ‘Study on the Activity Model of PbO-ZnO-FeO-Fe2O3-SiO2-CaO Six-Component High-Lead Slag System’. In this study, combined with the high-temperature phase diagram of the binary slag system and the ternary slag system in the PbO-ZnO-FeO-Fe2O3-SiO2-CaO six-component slag system, the structural units existing in the slag were determined, and the sum of the action concentrations of all components was stipulated to be equal to 1. Based on the principle of mass conservation of each component of the slag, a component action concentration (activity) model was established to analyze the influence of slag composition changes on the activity of each structural unit. The results show that the calculated value of the activity model is in good agreement with the measured value of the experiment, and the activity of each structural unit is greatly affected by the composition of the slag, but less affected by the temperature. High temperatures are conducive to the decomposition of lead silicate and the formation of calcium-containing compounds, but under such conditions, the activity of ZnO will *** Special Issue of Metals was well supported by diverse submissions and a final book publication of ten high-quality peer-reviewed articles.

摘要： Background/Objectives: Heart failure (HF) constitutes a complex clinical syndrome that is highly prevalent worldwide, comprises a serious prognosis, and results in a reduced quality of life. Exercise capacity is one of the most significant parameters involved in the prognosis in HF patients. Our objective was to evaluate the relationship between the selected cardiopulmonary exercise testing (CPET) parameters and the concentration of novel biomarker sST2 in a group of patients with heart failure with reduced ejection fraction (HFrEF). Methods: A group of 135 patients with HFrEF was enrolled in this prospective cohort study. Patients were in the stable phase of the disease in the prior 4 weeks and received optimal medical treatment. Clinical and biochemical parameters were investigated. All patients performed maximal CPET. Results: The mean (SD) concentration of sST2 was 45.5 ± 39.2 ng/mL. Based on the CPET results, the cut-off value (52.377 ng/mL) was established, optimal for the discrimination of relative peakVO2 < 12 mL/kg/min. Patients were divided into two groups according to sST2 cut-off values determined with an ROC curve (AUC 0.692, 95% CI: 0.567–0.816). The mean relative peakVO2 in patients with higher sST2 was 14.5 ± 4.6 mL/kg/min, while in the second group, it was 17.6 ± 5.2 (p = 0.002). In the sST2 ≥ 52.377 ng/mL group, 55.6% of patients achieved VO2 < 50%. Subjects with lower sST2 values obtained higher values of PETCO2 (p < 0.001) and higher values of pulse O2 (p = 0.01). VE/VCO2slope (p = 0.002) was higher in patients with increased sST2 concentration. Conclusions: The concentration of sST2 protein is substantially associated with the clinical severity of heart failure with reduced left ventricular ejection fraction assessed by functional capacity through CPET.
