    Influence of nitrogen doping on the electrocatalytic activity of Ni-incorporated carbon nanofibers toward urea oxidation by Barakat, Nasser A.M.

    Published 2017
    “…However, the electrochemical measurements indicated that the content of the urea in the initial electrospun solution should be optimized as the results showed that the best nickel surface activation as well as the maximum observed current density can be achieved when the urea content is kept at 5 wt%. Typically, the observed current densities using 1.0 M urea (in 1 M KOH) were 3.15, 29.7, 13.75, 47.55, 14.13 and 9.85 mA/cm2 for the nanofibers obtained from electrospun solutions having 0, 1, 2, 5, 7 and 9 wt% urea, respectively. …”

    Global age-sex-specific mortality, life expectancy, and population estimates in 204 countries and territories and 811 subnational locations, 1950–2021, and the impact of the COVID-... by Schumacher, Austin E.

    Published 2024
    “…Uncertainty intervals (UIs) were calculated for every metric using the 25th and 975th ordered values from a 1000-draw posterior distribution. Findings: Global all-cause mortality followed two distinct patterns over the study period: age-standardised mortality rates declined between 1950 and 2019 (a 62·8% [95% UI 60·5–65·1] decline), and increased during the COVID-19 pandemic period (2020–21; 5·1% [0·9–9·6] increase). …”

    Changes in carbohydrate and nitrogen fractions during germination of fenugreek (Trigonellafoenum-graecum L.) seeds presoaked in GA3, growing under different osmotic potentials by Al Hadi, F.A.

    Published 1997
    “…The response of total nitrogen was variable; it increased considerably in -0.1 and -0.3 MPa osmotic potential, then dropped sharply at -0.5 and -0.8 MPa. Similar behavior was found in TSN(Total Soluble Nitrogen), whereas protein-N changed only slightly and proline was accumulated substantially by decreasing the osmotic potential of the seed media. …”
