introduction: controlling parenchymal hemorrhage, especially in liver, is still one of the challenges surgeons face with when they try to save the patients’ lives despite improvements in surgical procedures. there is a research contest between the researchers in this field to introduce more effective methods. this study aimed to compare the hemostatic effect of ferric sulfate and ferric chlorid...

Using density functional theoryþHubbard U (DFTþU) calculations, we investigate how aluminum affects the spin crossover of iron in MgSiO3 perovskite (Pv) and post-perovskite (Ppv), the major mineral phases in the Earth’s lower mantle. We find that the presence of aluminum does not change the response of iron spin state to pressure: only ferric iron (Fe3þ) in the octahedral (B)-site undergoes a c...

The magnitude and temperature-sensitivity of oxygen isotope fractionation in ferric oxide-water systems remain uncertain. In this study, three different synthetic methods are used to investigate the temperature dependence of the fractionation between water and hematite, akaganeite, and goethite at near-surface temperatures. Our results reveal two similarities among these ferric oxide-water syst...

Nonylphenol (NP) is an ultimate degradation product of nonylphenol polyethoxylates (NPE) that is primarily used in cleaning and industrial processes. Its widespread use has led to the wide existence of NP in various environmental matrices, such as water, sediment, air and soil. NP can be decreased by biodegradation through the action of microorganisms under aerobic or anaerobic conditions. Half...
