    Design and analysis of PV fed high-voltage gain DC-DC converter using PI and NN controllers by Madisa V.G., Varaprasad

    Published 2022
    “…When the converter switch comes under active state two capacitors are discharged in series, similarly when the converter switch under inactive state those two capacitors are charged in parallel through the coupled inductor (CI) energy so, to get a high voltage at the converter output side. To reuse the leakage-inductor (LI) energy of the CI with the help of a passive clamp circuit for reducing the voltage stress across the switch, similarly switch has less resistance so conduction losses also decreased. …”

    Investigating the utilization of healthcare services to manage respiratory tract infections (RTIs) among Qatari patients attended selected primary healthcare centers in Qatar by Islam, Nazmul

    Published 2018
    “…We have found no difference in the month-to-month rates of RTI-related GP visits (per 1000 total visits) over the study period (non-significant decreasing trend). However, there was a significant decreasing trend in the monthly rates of antibiotics consumption and an increasing trend in the tests/investigations done but there was no clear increasing or decreasing trend in the monthly rates of other medications use. …”

    Thermally assisted efficient electrochemical lithium extraction from simulated seawater by Yanxi, Yu

    Published 2022
    “…The integrated thermally regenerative electrochemical cycle can harvest thermal energy in heated source solutions, enabling a low electrical energy consumption (11.3–16.0 Wh mol-1 lithium). Furthermore, the coupled thermal-driven membrane process in the system can also produce freshwater (13.2 kg m-2 h-1) as a byproduct. …”

    Community structure and activity of a highly dynamic and nutrient-limited hypersaline microbial mat in Um Alhool Sabkha, Qatar by Al-Thani, Roda

    Published 2014
    “…We investigated the chemical composition, the microbial activity and biodiversity of the four main layers (L1-L4) in the photosynthetic mats. Chlorophyll a (Chl a) concentration and distribution (measured by HPLC and hyperspectral imaging, respectively), the phycocyanin distribution (scanned with hyperspectral imaging), oxygenic photosynthesis (determined by microsensor), and the abundance of photosynthetic microorganisms (from 16S and 18S rRNA sequencing) decreased with depth in the euphotic layer (L1). …”
