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 ... -
Degraded Arid Soil Reclamation for Cotton Cultivation Using Organic Waste Amendments
(2024 , Conference Paper)Qatar is one of the most fertilizer-dependent countries due to challenging soil and climatic conditions. The country strives toward self-sufficiency in agricultural production in alignment with the Qatar National Vision ... -
Degrees of Freedom of the Full-Duplex Asymmetric MIMO Three-Way Channel with Unicast and Broadcast Messages
( Institute of Electrical and Electronics Engineers Inc. , 2017 , Conference Paper)In this paper, we characterize the total degrees of freedom (DoFs) of the full-duplex asymmetric multiple-input multiple- output (MIMO) three-way channel. Each node has a separate-antenna full-duplex MIMO transceiver with ... -
Dehydration of Ethanol over HF-treated Al2 O3 using the GC-column as Chemical Reactor
( Qatar University , 1981 , Article)The effect of treating •y-alumina with hydrofluoric acid on the dehydration reaction of ethanol was investigated at 325°C. The gas chromatographic column was used as a chemical reactor. The rate of formation of ethylene ... -
Delay analysis of converged optical-wireless networks with quality of service support
( Institution of Engineering and Technology , 2014 , Article)The convergence of two popular access technologies, namely Worldwide interoperability for Microwave Access (WiMAX) and passive optical network (PON) is a promising access solution that combines the mobility feature of WiMAX ... -
Delay Damages: The Application of Qatari National to Article 8(8) of the 2017 Red Book
( Brill Academic Publishers , 2020 , Article)This article addresses a common conundrum when a government is a party to a Red Book contract, that is governed by Qatari national law: the inter-relationship between national law and the voluntarily agreed-upon contractual ... -
Delay minimization through joint routing and resource allocation in cognitive radio-based mesh networks
( IEEE , 2012 , Conference Paper)We consider wireless mesh networks in which the nodes are utilizing cognitive radios and try to opportunistically gain access to spectrum resources. In such networks, the timely delivery of the traffic is a challenging ... -
Delay or travel time information? The impact of advanced traveler information systems on drivers’ behavior before freeway work zones
( Elsevier , 2022 , Article)Peak travel times contribute to congestion formation at freeway work zones. Advanced Traveler Information Systems (ATIS) can inform drivers in real-time about the delays and travel times en-route and can provide information ... -
Delay-Aware Flow Scheduling in Low Latency Enterprise Datacenter Networks: Modeling and Performance Analysis
( Institute of Electrical and Electronics Engineers Inc. , 2017 , Article)Real-time interactive application workloads (e.g., Web search, social networking, and so on) appear in the form of a large number of mini requests and responses flowing over the datacenters' networks. They end up being ... -
Delay-Aware Scheduling and Resource Optimization with Network Function Virtualization
( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)To accelerate the implementation of network functions/middle boxes and reduce the deployment cost, recently, the concept of network function virtualization (NFV) has emerged and become a topic of much interest attracting ... -
Delays in radical prostatectomy for prostate cancer and survival outcomes.
( Springer Verlag , 2018 , Article)A recent publication in your journal, involving 619 Canadian patients undergoing radical prostatectomy (RP), suggests increased delays to time of surgery may be associated with higher rates of biochemical recurrence(BCR)1 ... -
Deletion of potD, encoding a putative spermidine-binding protein, results in a complex phenotype in Legionella pneumophila
( Elsevier GmbH , 2014 , Article)L. pneumophila is an intracellular pathogen that replicates in a membrane-bound compartment known as the Legionella-containing vacuole (LCV). We previously observed that the polyamine spermidine, produced by host cells or ...
