The empirical parameters of mixing enthalpy (ΔHmix), entropy (ΔSmix), atomic radius difference (δ), valence electron concentration (VEC), etc., are used in this study to design a depleted uranium high-entropy alloy (HEA). X-ray diffraction (XRD), scanning microscopy (SEM), and transmission (TEM) were assess the phase composition. Compression hardness tests conducted select constituents with out...

introduction:maternal diabetes mellitus is associated with depleted fetal iron stores and this is proportionate to the degree of maternal control, presence or absence of diabetes-related complications, and is not related to maternal iron status. in this study, we aim to assess the effect of maternal diabetes on cord blood serum ferritin. methods: the present prospective (case-control) study was...

introduction: recently depleted uranium is being widely used as anti-armour ammunition and at very high temperature, results in information of an aerosol of very small uranium oxide particles, which may be inhaled. it is alleged that these particles represent a new battlefield hazard because of the chemical toxicology and/or radioactivity. method & materials: male wistar strain albino rats were...

bonding brackets to the enamel surface has gained much popularity today. new adhesive systems have been introduced and marketed and a considerable increase in research regarding bond strength has been published. a considerable amount of these studies deal with shear bond strength of adhesives designed for orthodontic purpose. previous studies have used variety of test designs. this diversity in...

This study investigates the effect of cement on the performance of soil, collected from Khanjahan Ali Hall at Khulna University of Engineering & Technology (KUET) in Khulna, Bangladesh. The addition of cement was found to improve the engineering properties of available soil in stabilized forms specifically strength, workability, and compaction and compressibility characteristics. Therefore, lab...

[1] A number of competing theories to explain the initiation mechanism, longevity and propagation characteristics of the Madden-Julian Oscillation (MJO) have been developed from observational analysis of the tropical climate and minimal dynamical models. Using the isotopic composition of atmospheric moisture from paired satellite retrievals of H2O and HDO from the boundary layer and mid troposp...

uniaxial compressive strength (ucs) and internal friction coefficient (µ) are the most important strength parameters of rock. they could be determined either by laboratory tests or from empirical correlations. the laboratory analysis sometimes is not possible for many reasons. on the other hand, due to changes in rock compositions and properties, none of the correlations could be applied as an ...
