Deconstructing the Gulf Crisis: Post-Colonialism and Competing ‘Projects’ in the Middle East
( SETA Foundation , 2020 , Article)This article deconstructs the stated reasons behind the quartet’s blockade on Qatar, including i) Iranian-relations; ii) funding ‘terror;’ iii) supporting ‘political Islam’ –Hamas, Muslim Brotherhood, etc.; and iv) ... -
Degeneration and the demos in North Africa: towards a ‘critical’ study of democratisation?
( Taylor & Francis , 2023 , Article)This article frames the problematic explored in the Special Issue, namely, the Maghreb and North Africa's ‘crisis of democratization.' Across cases, the crisis is multi-layered, involving first, counter-revolution since ... -
Degradation of Diallyl Phthalate (DAP) by fenton oxidation: Mechanistic and kinetic studies
( MDPI AG , 2018 , Article)In this work, the degradation and mineralization of Diallyl Phthalate (DAP) in water by Fenton oxidation was investigated. The effects of different experimental parameters including the initial pH, the hydrogen peroxide ... -
Degradation of hydroxychloroquine by electrochemical advanced oxidation processes
( Elsevier , 2020 , Article)In this work, the degradation of hydroxychloroquine (HCQ) drug in aqueous solution by electrochemical advanced oxidation processes including electrochemical oxidation (EO) using boron doped diamond (BDD) and its combination ... -
Degradation-fragmentation of marine plastic waste and their environmental implications: A critical review
( Elsevier , 2022 , Article Review)This review critically evaluates the plastic accumulation challenges and their environmental (primarily) and human (secondarily) impacts. It also emphasizes on their degradation and fragmentation phenomena under marine ... -
Delicate Structural Control of Si-SiOx-C Composite via High-Speed Spray Pyrolysis for Li-Ion Battery Anodes
( American Chemical Society , 2017 , Article)Despite the high theoretical capacity, silicon (Si) anodes in lithium-ion batteries have difficulty in meeting the commercial standards in various aspects. In particular, the huge volume change of Si makes it very challenging ... -
“DELIVER AMAZING”: Qatar as a branded architectural discourse in World Cup 2022
( Routledge , 2020 , Book chapter)Qatar brands itself as a projected-in-the-future proud cosmopolitan and progressive country ready to host World Cup 2022. The branding practices, whereby this projection takes place, are the focus of Irene Theodoropoulou’s ... -
Density functional theory study on the catalytic dehydrogenation of methane on MoO3 (010) surface
( Elsevier , 2022 , Article)Methane conversion offers hydrocarbon building blocks of high market value, which are easier to transport than natural gas. Under non-oxidative conditions, the process can also produce clean hydrogen fuel. In this study, ... -
Density manifolds, geometric measures and high-energy physics in transfinite dimensions
( Elsevier B.V. , 2009 , Article)We discuss certain manifolds with density. Furthermore, we outline natural connections leading to E-infinity theory and high-energy physics from a geometric measure and transfinite dimensional theoretical viewpoints. -
