The two-phase alloy Zr–2.5Nb, a high-strength alloy for nuclear applications, has a grain structure in which the hcp a-phase is surrounded by the bcc b-phase. A satisfactory method for the macroscopic overall properties of this type of materials has yet to be developed. Based on the small volume fraction of the b-phase, some existent models of polycrystalline aggregates of Zr–2.5Nb argued to co...

background: women with polycystic ovary syndrome have lower pregnancy rates, possibly due to the decreased uterine  receptivity.successful implantation depends on protein networks that are essential for cross-talk between the embryo and endometrium.apolipoprotein a1 has been proposed as a putative anti-implantation factor. in this study, we evaluated apolipoprotein a1 expression in human endome...

after designing and constructing a coalescence cell, drop/interface coalescence phenomenon was studied in the absence and presence of single surfactant.two surface active agents of sodium dodecyl sulfate and 1-decanol were used. distilled water was used as dispersed phase. toluene, n-heptane and aqueous 60% (v/v) of glycerol were selected as continuous phases, separately. it was found that the ...

STUDY OBJECTIVES Computational tools that predict the effects of daily sleep/wake amounts on neurobehavioral performance are critical components of fatigue management systems, allowing for the identification of periods during which individuals are at increased risk for performance errors. However, none of the existing computational tools is publicly available, and the commercially available too...

Within this work the effect of B content on microstructure, phase composition and mechanical properties CVD Ti(B,N) coatings is investigated. with contents from 0 (fcc-TiN) to ∼5, ∼15, ∼30, ∼45 66 (h-TiB2) at.% have been deposited by CVD. The elemental was confirmed ERDA their microstructure investigated using XRD SEM. With increasing content, a transition fcc h-dominated structure via dual-pha...

Maintaining weight loss after the initial phases of any weight loss intervention is a challenge. Rationally, it depends on how well the adherence is to the prescribed treatment. This study is to test the sustainability of an intervention in maintaining weight lost during Ramadan by using voluntary fasting. Methods: Two groups of respondents (Muslim women with body mass index (BMI) ≥ 25.0 kg/m2)...

Mispronunciation is still among the frailties of language learners the world over. The present study reports an all-out investigation into pronunciation training for the Persian-speaking EFL learners at the intermediate level of language proficiency. More specifically, the present study investigated (a) the underlying causes of mispronunciation at the level of segmental features, (b) the crucia...

Single crystals of poly(ethylene glycol) (PEG)-b-polystyrene (PS), PEG-b-poly(methyl methacrylate) (PMMA), PEG-b-polycaprolactone (PCL), and polyaniline (PANI)-b-PEG-b-PANI were developed from dilute solutions and thin molten films using self-seeding methodology. The PS and PMMA grafted chains were categorized in disordered nano-brushes; however, the PCL and PANI ones were grouped in ordere...
