Recent advances on humic acid removal from wastewater using adsorption process
( Elsevier , 2023 , Article Review)Humic acid (HA) is a component of natural organic matter (NOM) with a high molecular weight and high complexity. The presence of humic acid in water raises serious concerns due to its toxicity and ability to form carcinogenic ... -
Recent developments in forward osmosis membranes using carbon-based nanomaterials
( Elsevier , 2020 , Article Review)Contamination and industrial development are among the reasons for water quality deterioration beyond treatability by conventional processes. Unfortunately, conventional water and wastewater treatment technologies are not ... -
Recent issues on stadium monitoring and serviceability: A review
( Springer New York LLC , 2016 , Book chapter)Unlike most of civil engineering structures whose static and dynamic responses are estimated accurately through several codes and guidance, stadiums reserve a distinctive place especially when it comes to their dynamic ... -
Recycling of Local Qatar’s Steel Slag and Gravel Deposits in Road Construction
( OMICS International , 2014 , Article)Every year, the State of Qatar generates about 400,000 tons of steel slag and another 500,000 tons of gravel as a result of steel manufacturing and washing sand, respectively. The two materials (by-products) are not fully ... -
Reducing railway-induced ground-borne vibration by using open trenches and soft-filled barriers
( Elsevier Ltd , 2016 , Article)A trench can act as a barrier to ground vibration and is a potential mitigation measure for low frequency vibration induced by surface railways. However, to be effective at very low frequencies the depth required becomes ... -
Release of colloids in saturated porous media under transient hydro-chemical conditions: A pore-scale study
( Elsevier , 2021 , Article)The deposition and consequent release of colloids pose a significant challenge to the environment, groundwater quality and human health. Subsurface soil contains numerous types of colloids that exhibit a diverse range of ... -
A reliability-based weather-responsive variable speed limit system to improve the safety of rural highways
( Elsevier , 2022 , Article)Weather-responsive Variable Speed Limit (WRVSL) systems treat speed limits as weather-dependent random variables, as opposed to the conventional static speed limits. This study (i) evaluates drivers’ response to a fixed ... -
Reliable tuberculosis detection using chest X-ray with deep learning, segmentation and visualization
( Institute of Electrical and Electronics Engineers Inc. , 2020 , Article)Tuberculosis (TB) is a chronic lung disease that occurs due to bacterial infection and is one of the top 10 leading causes of death. Accurate and early detection of TB is very important, otherwise, it could be life-threatening. ... -
Removal of petroleum hydrocarbons and sulfates from produced water using different bioelectrochemical reactor configurations
( Elsevier B.V. , 2019 , Article)Produced water (PW) is a wastewater generated in large quantities from the extraction of oil and gas. PW found to have high amounts of dissolved solids (TDS) and residual petroleum hydrocarbons causing considerable damage ... -
