Database Facilitated Screening with NMR Spectroscopy Analysis for Drug Detection
( IEEE , 2019 , Conference Paper)© 2019 IEEE. Drug detection plays the key role in the enforcement of drug regulations. Various detection methods for them are thus developed. However, in most investigations, the most time-consuming and tedious part is not ... -
Dataset of allelopathic effects of Casuarina equisetifolia-L leaf aquatic extract on seed germination and growth of selected plant crops
( Elsevier Inc. , 2019 , Article)In agricultural fields that are surrounded by dunes, the Casuarina tree is usually used as windbreaks. In addition, it plays a significant role in inhibiting nearby vegetation growth. In this dataset, the effect of Casuarina ... -
Date palm fibre filled recycled ternary polymer blend composites with enhanced flame retardancy
( Elsevier Ltd , 2017 , Article)Flammability of recycled polypropylene (PP)/low density polyethylene (LDPE)/high density polyethylene (HDPE) ternary blends containing date palm fibres is investigated in this study. Melt blending is used for the composite ... -
The date palm microbiome: A review
( Elsevier , 2023 , Article)Date palm (Phoenix dactylifera) is a significant crop grown in warm, tropical, and arid regions. The microorganisms associated with plants can have positive and negative effects on the growth and yield of crops. Thus, there ... -
Date palm status and perspective in qatar
( Springer Netherlands , 2015 , Article)Qatar ranks as the 16 largest date-producing country in the world. There are 581,336 date palm trees growing in an area of 2,469 ha with date production of 21,491 mt as of 2010. It is the major fruit tree grown in the ... -
Date palm wood flour/glass fibre reinforced hybrid composites of recycled polypropylene: Mechanical and thermal properties
( Elsevier, Ltd , 2012 , Article)Recycled polypropylene (RPP) based hybrid composites of date palm wood flour/glass fibre were prepared by different weight ratios of the two reinforcements. Mixing process was carried out in an extruder and samples were ... -
Date pits based nanomaterials for thermal insulation applications - Towards energy efficient buildings in Qatar
( Public Library of Science , 2021 , Article)Air-conditioning systems make the most significant part of energy consumption in the residential sector. There is no denying that it is essential to produce a comfortable indoor thermal environment for residents in a ... -
Decentralized Unitary System: A Possible Middle Ground for Somalia
( Center for Research and Policy Studies , 2015 , Article)The debate over a suitable governance model for Somalia is re-examined using material gleaned from interviews, focus-groups, document analyses and literature. Analysis first identifies four domestic grievances – trust-deficit, ... -
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
