The prooxidant-antioxidant balance in diagnosis and developmental prognosis of premature neonates with asphyxia.

Background: The antioxidant system in a preterm neonate is premature. The imbalance between the prooxidant and antioxidant systems can make these neonates prone to oxidative stress. Birth asphyxia is one of the factors that can disturb this balance.

A first step towards understanding thermomechanical behavior of the Nb-Cr system through interatomic potential development and molecular dynamics simulations.

Utilizing a preliminary interatomic potential, this work represents an initial exploration into the thermomechanical behavior of NbCr solid solutions. Specifically, it examines the effect of different amounts of Cr solute, for which information in the literature is limited. The employed interatomic potential was developed according to the embedded atom model (EAM), and was trained on data derived from density functional theory calculations.

Impact of Dilute Amounts of Fission Products on the Mechanical Behavior of Ni.

Fission products may interact with structural materials in various nuclear energy applications and cause their mechanical performance to deteriorate. Therefore, it is important to study the effects of different fission products on the mechanical properties of structural materials. In this work, nickel was chosen as a model structural material system and dilute amounts of uranium and fission product impurities X = (Tc, Te, Sb, Ce, Eu, and U) up to 4 at % were used.

A Survey on Diagnosis and Prognosis of Prenatal Asphyxia based on Antioxidant Oxidant Balance: Evidence from a Systematic Review and Meta-Analysis.

Introduction: The mechanism of occurrence and complications of asphyxia change in the treatment process and the future prognosis of newborns. One of the discussed mechanisms is the disruption of oxidants to anti-oxidants balance. Therefore, the current study was conducted aiming to systematically review and conduct a meta-analysis on the diagnosis and prognosis of prenatal asphyxia based on oxidant-antioxidant balance.

Adsorption of Oxygen to High Entropy Alloy Surfaces for up to 2 ML Coverage Using Density Functional Theory and Monte Carlo Calculations.

High-entropy alloys (HEAs) manufactured with refractory elements are candidates for high-temperature structural applications. To enhance our understanding of oxidation in these complex systems, the early stages of oxidation on the surface of AlNbTaTiZr were studied using density functional theory and thermodynamic modeling. Surface slabs were generated from bulk configurations sampled from equilibrium using a multicell Monte Carlo method for phase prediction.
