    Ferroelectric Properties and Electrocaloric Effect in Dy2O3 Substitution on Lead-Free (Na0.5 Bi0.5)0.94 Ba0.06TiO3 Ceramic حسب Turki, O.

    منشور في 2023
    "…Higher stability of the ferroelectric (FE) phase was obtained at room temperature for the compositions y = 0.01, 0.02 and 0.05, with optimum values for y = 0.02 as remanent polarization Pr = 32µC/cm2, as well as piezoelectric coefficients d33 = 137 pC/N, kp = 0.27 and kt = 0.16, whereas a higher content of Dy (y = 0.08) induced a remarkable decrease of the ferroelectric and piezoelectric properties. …"

    Use of Electrical Resistivity Tomography to Study the Impact of Long-Term Application of Sewage Sludge: Case Study of Oued Souhil Experimental Station, Nabeul (Tunisia) حسب Hechmi, Sarra

    منشور في 2022
    "…Laboratory analyses were conducted on soil samples taken in the middle of the treated plots at four depths (0–20 cm), (20–40 cm), and (40–60 cm) for a comparison with the ERT survey result. ERT panels showed a general decrease in soil resistivity below (40 cm) with extremely low resistivity in each plot’s corner, indicating a vertical leaching and a lateral migration of conductive materials in all the treatments. …"

    Failure mode analysis for single-phase Multi-level qZSI interfacing PV system to utility grid حسب Rahman, Syed

    منشور في 2017
    "…In this paper, control algorithm for the operation of Multi-level qZSI with module failures (up to three modules out of total 16) is discussed. The power deficit due to a failure of the module is reflected as a decrease in the grid current reference. …"

    Estimating and decomposing changes in the White–Black homeownership gap from 2005 to 2011 حسب Seah, Kiat Ying

    منشور في 2015
    "…In fact, we find that the gap decreased for households that were the least likely to own and remained unchanged for households that were the most likely to own, and that Black households with around a 50% probability of homeownership were especially vulnerable to the crisis. …"

    Perinatal outcomes following Helping Babies Breathe training and regular peer-peer skills practice among village midwives in Sudan. حسب Arabi, Ame

    منشور في 2017
    "…Excluding 11 macerated fetuses, there were 55 perinatal deaths: 14 FSB/18 ENND (6 months pre-HBBT(+RPPSP)) and 10 FSB/13 ENND (18 months post-HBBT(+RPPSP)). FSB rates decreased from 10.5 to 3.3 per 1000 births ((χ(2))=8.6209, p=0.003), while ENND rates decreased from 13.5 to 4.3 per 1000 live births ((χ(2))=10.9369, p=0.001) pre-HBBT(+RPPSP) and post-HBBT(+RPPSP), respectively. …"
