Enhancement of Naphthalene Biodegradation by Sulfate Application in Brackish Subsurface Systems
(
Qatar Univesrity Press
, 2020 , Conference Paper)
Anaerobic biodegradation is the most dominant mechanism in the petroleum hydrocarbon
contaminated subsurface systems. Due to depletion of terminal electron acceptors such
as sulfate, anaerobic degradation of organic ...
Impact of Ionic Strength on Colloid Retention in a Porous Media: A Micromodel Study
(
Qatar Univesrity Press
, 2020 , Conference Paper)
Release of deposited colloids in the soil porous media during two-phase flow poses
potential health hazard due to the facilitated transport of contaminants towards
groundwater reservoirs. Considerable uncertainties exist ...
Utilizing Steel Slag in the Removal of Suspended Solids from Dewatered Construction Water
(
Qatar Univesrity Press
, 2020 , Conference Paper)
Construction dewatering is an operation used to remove shallow groundwater that
infiltrates construction sites. After recovering this water from the construction sites, the
water is either discharged to the sea, injected ...
The Use of Measuring While Drilling and Wireline Logging to Identify the Geological Strata in Qatar
(
Qatar Univesrity Press
, 2020 , Conference Paper)
In the field of engineering and construction in the Middle East, it is a common practice to
economize a geotechnical investigation using a conventional scope, based on the lowest
price. This tends to compromise the project ...
Box Jacking/Pushing Method for Tunnel Construction in Rock: Doha Metro, Gold Line Project
(
Qatar Univesrity Press
, 2020 , Conference Paper)
The case of a box pushing tunneling method in rock, on Doha Metro Gold Line project,
successfully implemented to connect multiple entrance structures of Sport City station
under a live traffic junction, in a heavy urban ...
Influence of Aspect Ratio on the Bearing Capacity and Correlated Modulus of Subgrade Reaction for Shallow Foundations on Dense Sand
(
Qatar Univesrity Press
, 2020 , Conference Paper)
One of the most fundamental problems in the field of geotechnical engineering is the
prediction of bearing capacity and settlement of shallow foundations on cohesion-less
soil subjected to vertical central loading. The ...
Investigation of the Effect of the Force-Frequency on the Behaviour of a New Viscous Damper for Railway Applications
(
Qatar Univesrity Press
, 2020 , Conference Paper)
The primary purpose of this work is to experimentally investigate the damping
coefficient of a viscous damper, intended to be used in railway applications to reduce
noise emission. The viscous shock absorber used in this ...
Resource Recovery from Waste, Water and Wastewaters with Membrane Technologies
(
Qatar Univesrity Press
, 2020 , Conference Paper)
In this study, critical elements (Boron (B) and Rare Earth Elements (REE)) recovery is
studied with membrane technologies. Concentrated boron can be recovered by using
different technologies. Membrane technologies such as ...
Impact of Draw Solution Concentration on Forward Osmosis Process: A Simulation Study
(
Qatar Univesrity Press
, 2020 , Conference Paper)
In this study, a simulation model was used to evaluate the performance of forward
osmosis process. A solution of low salinity was used as the feed solution in forward
osmosis to dilute saline solution (i.e. draw solution) ...
Use of 3D Images to Evaluate Formation Damage Induced by Montmorillonite Fines in Porous Media Systems
(
Qatar Univesrity Press
, 2020 , Conference Paper)
Formation damage costs oil and gas industry $140 billion/year in lost productivity, this
is a key challenge to Qatar, the world's largest LNG exporter. During production from
a well, multiphase flow foster drag forces to ...
