Effects of environmental and climatic conditions on PV efficiency in qatar
منشور في 2013"…The study shows that Amorphous PVs are more robust against dust settlement than Mono-crystalline PVs and hence are more suitable for implementation in desert climates like Qatar. It was estimated that 100 days of dust accumulation over Mono-crystalline PV panels, caused the efficiency to decrease by 10%. …"

EPIDEMIOLOGY OF CHLAMYDIA TRACHOMATIS IN LATIN AMERICA AND THE CARIBBEAN: SYSTEMATIC REVIEW, META-ANALYSES, AND META-REGRESSIONS
منشور في 2022"…We conducted random-effects meta-regressions to identify sources of heterogeneity and possible predictors of high prevalence. Results: The pooled-mean urogenital CT prevalence was 8.2% (95% CI: 7.5-9.1) for general populations, 14.0% (95%CI: 12.7-15.4) for female sex workers, 10.8% (95% CI: 8.4-13.4) for men who have sex with men, male sex workers, and transgenders, 16.1% (95% CI: 12.6-19.8) for symptomatic women, 25.4 (95% CI: 18.6-38.5) for symptomatic men, 9.7% (95%CI: 6.1-14) for HIV-positive individuals and individuals in HIV-discordant couples, and 11.9% (95 CI: 8.5-15.8) for STI clinic attendees. …"

Study of the effects of dust, relative humidity, and temperature on solar PV performance in Doha: Comparison between monocrystalline and amorphous PVS
منشور في 2013"…However, amorphous PVs prove to be more robust against dust settlement than monocrystalline PVs and hence are more suitable for implementation in desert climates like Doha unless cleaning strategies are devised. It was estimated that 100 days of dust accumulation over monocrystalline PV panels, caused the efficiency to decrease by around 10%. …"
