Strain-rate sensitivity of high-entropy alloys and its significance in deformation

open access: yesMaterials Research Letters, 2019
Strain-rate dependence in face centered cubic high entropy alloys still remains controversial despite extensive efforts on this topic. Strain-rate sensitivity reflects underlying thermally-activated deformation and the controversy boils down to the ...

Additional studies on heterodiffusion coefficients in periclase [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2012
By using a thermodynamical model, the activation entropy is extracted from the experimental diffusion data of Al in MgO. Furthermore, we estimate the activation volume. We find a value for the activation entropy of (4.21 ± 0.05) k.

Probing the impact of grain interior and grain boundaries on the mechanical behavior of a high-Mn austenitic steel

open access: yesJournal of Materials Research and Technology, 2022
We elucidate here the grain orientation/grain boundary dependence on the deformation behavior of high-Mn steel via tensile tests. The ultra-fine grained/fine grained (UFG/FG) specimen was characterized by superior strength-ductility combination as ...

Plasma Levels of Soluble P-Selectin, Beta-Thromboglobulin and Platelet Indices in Patients With Prediabetes: Effects of Acute Hyperglycemic Stress

open access: yesEndocrinology Research and Practice, 2022
Objective: To examine the effects of acute hyperglycemic stress on platelet activation by analyzing the plasma levels of P-selectin, beta-thromboglobulin, and platelet indices in an oral glucose tolerance test (OGTT).

Nucleation on active centers in confined volumes [PDF]

open access: yesThe Journal of Chemical Physics, 2012
Kinetic equations describing nucleation on active centers are solved numerically to determine the number of supercritical nuclei, nucleation rate, and the number density of nuclei for formation both of droplets from vapor and also crystalline phase from vapor, solution, and melt.

Use of mean platelet volume as a tool to assess the progression of type 2 diabetes mellitus

open access: yesNational Journal of Physiology, Pharmacy and Pharmacology, 2019
Background: Diabetes mellitus (DM) is characterized by chronic hyperglycemia resulting in micro- and macro-vascular complications and is correlated with glycemic control and its duration.

Therapeutic Apheresis for Intravenous Methylprednisolone‐Refractory Neuromyelitis Optica Spectrum Disorder: Clinical and Radiological Outcomes in a Single‐Center Case Series

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Neuromyelitis optica spectrum disorder (NMOSD) is a relapsing autoimmune disease of the central nervous system. High‐dose intravenous methylprednisolone (IVMP) is the standard first‐line therapy for acute attacks, although some patients remain refractory.

Activation Volume Measurements

open access: yesZeitschrift für Naturforschung A, 1971
Abstract The determination of the activation volume of diffusion is one of the best methods for the in­vestigation of the relaxation of atoms or ions around defects. This paper discusses two experimental techniques for the determination of the activation volume for diffusion, by studying the effect of hydrostatic pressure on tracer ...
