    Global, regional, and national stillbirths at 20 weeks' gestation or longer in 204 countries and territories, 1990–2021: findings from the Global Burden of Disease Study 2021 حسب Comfort, Haley

    منشور في 2024
    "…The estimated number of stillbirths occurring at 20 weeks' gestation or longer decreased from 5·08 million (95% UI 4·07–6·35) in 1990 to 3·04 million (2·61–3·62) in 2021, corresponding to a 39·8% (31·8–48·0) reduction, which lagged behind a global improvement in neonatal deaths of 45·6% (36·3–53·1) for the same period (down from 4·03 million [3·86–4·22] neonatal deaths in 1990). …"

    Facile Electrochemical Synthesis of Highly Efficient Copper-Cobalt Oxide Nanostructures for Oxygen Evolution Reactions حسب Nath, Narayan Chandra Deb

    منشور في 2020
    "…An optimized nanopetal structure of CuxCo3-xO4 (x = 0.95, annealed at 200 °C) shows a considerably high Faradaic efficiency (∼93%) with a remarkably low overpotential (∼230 mV) at a benchmark current density (J) of 10 mA cm-2; at the same J in an alkaline solution (1 M KOH) for OER, it also exhibits high durability (up to 100 h). …"

    Effect of the length of silicon nano-dot/wire on band gap حسب Hassan, Walid M.I.

    منشور في 2014
    "…We will report on the role of the length of silicon nanowire (SNW) in determining the band gap of a structure. We find that the band gap decreases with SNW length for the same diameter and approaches the band gap for an ideal infinitely long SNW. …"

    Emerging clay-aryl-gold nanohybrids for efficient electrocatalytic proton reduction حسب Jlassi, Khouloud

    منشور في 2018
    "…Both nanohybrids showed efficient electrochemical activity for HER in acidic condition (0.1 M H2SO4) with high current density up to −25 mA.cm−2 at −1 V and 0.148 mV onset. Negligible decreasing in current density and slight shift in onset was observed after 1000 cycles. …"

    Effects of Trehalose Administration in Patients with Mucopolysaccharidosis Type III. حسب Mobini, Moein

    منشور في 2023
    "…Mucopolysaccharidosis type III (MPS III) is a rare autosomal recessive lysosomal storage disease (LSD) caused by a deficiency of lysosomal enzymes required for the catabolism of glycosaminoglycans (GAGs), mainly in the central nervous system. …"

    Electrochemical oxidation of ammonia (NH4+/NH3) ON synthesized nickel-cobalt oxide catalyst حسب Almomani F.

    منشور في 2021
    "…The reported Pgen were 0.55, 0.85, 1.1 and 0.0.93 mW/cm2 for Ni–C, Co10/Ni–C, Co20/Ni–C and Co40/Ni–C. A concentration of Co higher than 40% decreased cell potential (Vcell) and reduced the percentage removal of ammonia (%REAmm). …"

    Long-Distance Vowel-to-Vowel Coarticulation in Arabic: Influences of Intervening Consonant Pharyngealization and Length حسب Ahmed, Sarah

    منشور في 2019
    "…Speakers of Egyptian Arabic were recorded saying sentences containing nonsense sequences of the form /baɁabaCV:/, where C was chosen from {/t/, /tˤ/, /t:/, /tˤ:/} and V was a long vowel /i:/, /a:/ or /u:/. Analysis of the first and second formants of the recorded vowels revealed that (a) vowel-to-vowel coarticulatory effects could sometimes extend to a distance of three vowels before the context vowel; (b) the consonant-to-vowel effects associated with pharyngealization were consistently seen at similar distances, while also decreasing in magnitude at greater distances from the triggering consonant; and (c) effects related to intervening consonant length were idiosyncratic, and in particular did not lead to consistent blocking of vowel-to-vowel effects. …"

    Tailoring the defects of sub-100 nm multipodal titanium nitride/oxynitride nanotubes for efficient water splitting performance حسب Eid, Kamel

    منشور في 2021
    "…These defects decreased the bandgap energy to 2.4 eV, increased visible-light response, and enhanced the incident photon-to-current collection efficiency (IPCE) and the photocurrent density of TiONxNTs by nearly 8 times compared with TiO2NTs, besides a quick carrier diffusion at the nanotube/electrolyte interface. …"
