WorldView-3 mapping of Tarmat deposits of the Ras Rakan Island, Northern Coast of Qatar: Environmental perspective
(
Elsevier
, 2021 , Article)
This study characterizes the spectral behavior of tarmats and maps the tarmat deposits found along the coast of Ras Rakan Island off Qatar using WorldView-3 (WV-3) sensor data. The laboratory spectra of tar materials showed ...
Investigation of flexible polymer-Tl2O3 nanocomposites for x-ray detector applications
(
Elsevier B.V.
, 2019 , Article)
We report on the synthesis and characterization of composite semiconducting polymer – nanoparticle membranes for X-ray detection applications. The membranes are made of poly(vinyl alcohol) (PVA) organic polymer that is ...
CFD analysis of turbulent flow of power-law fluid in a partially blocked eccentric annulus
(
MDPI AG
, 2021 , Article)
This study focuses on analyzing the turbulent flow of drilling fluid in inclined wells using the Computational Fluid Dynamics (CFD) technique. The analysis is performed considering an annulus with a fixed eccentricity of ...

(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
In this paper, we present a novel architecture based on field-programmable gate arrays (FPGAs) for the reconstruction of compressively sensed signal using the orthogonal matching pursuit (OMP) algorithm. We have analyzed ...
Brief Report: Polymorphisms in TNF-α/TNFR1 Pathway Genes Are Associated With CD4+ T-Cell Recovery in HIV-1–Infected Individuals on Antiretroviral Therapy
(
NLM (Medline)
, 2021 , Article)
Background:
Antiretroviral therapy (ART) is an important hallmark of HIV-1 treatment, enabling viral load suppression to undetectable levels and CD4+ T-cell recovery. However, some individuals do not recover the CD4+ ...
Removal of copper ions from aqueous solution using NaOH-treated rice husk
