Impact of urban sewage sludge on soil physico-chemical properties and phytotoxicity as influenced by soil texture and reuse conditions
(
Wiley
, 2020 , Report)
Urban sewage sludge (USS) is increasingly applied to agricultural soils, but mixed results have been reported because of variations in reuse conditions. Most field trials have been conducted in cropping systems, which ...
Conformal Invariants in Simply Connected Domains
(
Springer Link
, 2020 , Article)
This paper studies the numerical computation of several conformal invariants of simply connected domains in the complex plane including, the hyperbolic distance, the reduced modulus, the harmonic measure, and the modulus ...
Monitoring the variation of soil quality with sewage sludge application rates in absence of rhizosphere effect
(
Elsevier
, 2020 , Article)
Agricultural soils in semi-arid regions have frequently been degraded due to adverse climatic conditions, organic matter depletion, and poor farming practices. To enhance soil quality, this study examines the reuse of ...
Smart City Applications: Promoting comfort, health and well-being through Sustainable Smart Urban Design (S2UD) in Msheireb Downtown
(
Institute of Electrical and Electronics Engineers Inc. (IEEE)
, 2020 , Conference Paper)
This study explores the Msheireb Downtown Project by studying the design qualities and adopted applications of its public open spaces (POS). We uncover their roles in the smart city design system with an eye for how they ...
A framework for the analysis of damage and recovery characteristics of asphalt mixtures
(
Taylor & Francis
, 2020 , Article)
This study presents two approaches for evaluating damage and recovery characteristics of asphalt mixtures. The first approach focuses on determining damage by extracting recoverable viscoelastic strain that has no damage ...
Microstructure and mechanical behavior of hot extruded aluminum/tin-bismuth composites produced by powder metallurgy
(
MDPI AG
, 2020 , Article)
In this study, Al-BiSn composites were synthesized by a combination of microwave sintering and hot extrusion processes. The structural, morphological, mechanical, and thermal properties were investigated to elucidate the ...

BMJ Publishing Group
, 2020 , Other)
The COVID-19 pandemic has posed unprecedented health and social challenges. WHO has been working to promote the integration of mental health and psychosocial support into the COVID-19 response effort.1 It is vital that ...
Electrodeposition of Duplex Ni–B–Zn/Co Composite Coatings
(2020 , Article)
This research article focusses on the Ni–B–Zn/Co composite coatings synthesized via an electrodeposition process. Electrodeposited Ni–B composite coatings have several advantages, such as excellent corrosion as well as ...
Highly crystalline and thermally stable poly(aniline-co-2-nitroaniline)
(
Springer Nature
, 2020 , Article)
Abstract: To synthesize a crystalline polymer is unconventional. Here, we found the well-defined hexagonal or rectangular cubical shape of poly(aniline-co-2-nitroaniline)s PA-co-2-NAs through scanning electron microscopy. ...
A novel solar integrated distillation and cooling system – Design and analysis
(
Elsevier
, 2020 , Article)
To meet the high cooling and fresh water demands in hot and arid regions, a novel integrated solar cooling and solar distillation system is introduced. The system consists of a solar ejector cooling system integrated with ...
