Salicylic acid restricts mercury translocation by activating strong antioxidant defense mechanisms in sweet pepper (Capsicum annum L.) by Muhammad Fasih Khalid (10652246)

“…H₂O₂ was found to be lower in plants treated with SA under Hg toxicity than in non-treated plants. The SA application also restricts the accumulation of Hg in sweet pepper roots, leaves, and fruits. …”

New algorithm based active method to eliminate stick-slip vibrations in drill string systems by Fourat Zribi (21347900)

“…This phenomenon can decrease the rate of penetration of drilling, wear of expensive equipment prematurely and cause catastrophic failures. …”

Circular economy application for a Green Stadium construction towards sustainable FIFA world cup Qatar 2022™ by Abathar Al-Hamrani (16494884)

“…Therefore, sustainable construction became a hot topic, which strives to reduce material consumption, limit constructional waste disposal, and decrease contribution to climate change. In line with Qatar's commitment to organizing a sustainable FIFA World Cup in 2022, this study aims to conduct an environmental life cycle assessment (LCA) for the construction of the Education City Stadium. …”

Heat transfer measurements of Polyalpha-Olefin- boron nitride nanofluids for thermal management and lubrication applications by Ahmad K. Sleiti (14778229)
