Effect of salt concentration on osmotic potential in drying soils—Measurement and models
European Journal of Soil Science, Volume 75, Issue 5, September–October 2024.Abstract The water potential in drying soils, comprising both matric potential and osmotic potential components, can be measured using the dew point method (DPM). By combining DPM data with retention curve data acquired from techniques such as the suction plate method or the simplified evaporation method (SEM), it becomes possible to determine the soil

Review of the Predictive Value of Biomarkers in Sepsis Mortality
Emergency Medicine International, Volume 2024, Issue 1, 2024.Sepsis is a leading cause of mortality among severely ill individuals, primarily due to its potential to induce fatal organ dysfunction. For clinicians, it is vital to have appropriate indicators, including the physiological status and personal experiences of patients with sepsis, to monitor the condition and assess prognosis.
