Exploitation of Citrus Peel Extract as a Feedstock for Power Generation in Microbial Fuel Cell (MFC)
( Springer , 2019 , Article)Microbial fuel cells (MFCs) are envisioned as an evolving cost-effective process for treating organic wastes to simultaneously generate bioelectricity. Therefore, in present study a single chambered mediator- less air ... -
A comparison of ground vibration due to ballasted and slab tracks
( Elsevier Ltd , 2019 , Article)With the development of non-ballasted track forms (often referred to as slab tracks) over the few last decades, it is important to understand their behaviour with respect to ground-borne vibration compared with the traditional ... -
A shear design model for RC beams strengthened with fabric reinforced cementitious matrix
( Elsevier Ltd , 2019 , Article)The shear behavior of fabric reinforced cementitious matrix (FRCM) strengthened beams requires more research efforts to be fully understood. A detailed investigation into the shear capacity of FRCM shear-strengthened beams ... -
Enhancing the corrosion resistance of reinforcing steel under aggressive operational conditions using behentrimonium chloride
( Nature Research , 2019 , Article)Aggressive operational conditions e.g. saline media and acidic gases, e.g., CO2 can increase the corrosion rate of reinforcing steel. Accordingly, the necessity to protect the steel under the above conditions without ... -
Organically modified nanoclay filled thin-film nanocomposite membranes for reverse osmosis application
( MDPI AG , 2019 , Article)This study validates, for the first time, the effectiveness of two nanoclays, that is, cloisite (CS)-15A and montmorillonite (MNT) at the polyamide (PA) active layer in the reverse osmosis (RO) membrane. Cloisite-15A is ... -
Development, validation, and application of School Audit Tool (SAT): An effective instrument for assessing traffic safety and operation around schools
( MDPI AG , 2019 , Article)There is a need for a reliable school audit tool with well-defined scales to convert qualitative evaluation of existing school sites into a quantitative assessment in order to help public agencies to improve schools' safety ... -
A Case Study for Surrogate Safety Assessment Model in Predicting Real-Life Conflicts
( Springer Verlag , 2019 , Article)Conflict techniques enable transportation engineers to investigate hazardous network locations without the need to obtain crash data. These techniques are the most developed indirect measure of traffic safety. The concept ... -
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 ... -
Pull-off characterization of FRCM/Concrete interface
( Elsevier Ltd , 2019 , Article)Fabric-reinforced cementitious matrix (FRCM) composites are usually surface-applied for strengthening reinforced concrete (RC) structures. The efficacy of the FRCM strengthening systems is dependent on the FRCM/concrete ... -
NAVIGATION IN INDOOR VOXEL MODELS
( Copernicus GmbH , 2019 , Conference Paper)The paper proposes to use voxel models of building interiors to perform indoor navigation. The algorithms can be purely geometrical, not relying on semantic information about different building elements, such as floors, ... -
Employing biomimicry in Urban metamorphosis seeking for sustainability: Case studies
( Universitat Politecnica de Catalunya , 2019 , Article)Objective The current study has aimed to develop the framework of biomimicry involvement in urban metamorphosis for sustainability. This research has engaged four objectives to achieve the aim. Objective one is to explore ... -
User satisfaction and energy use behavior in offices in Qatar
( SAGE Publications Ltd , 2018 , Article)The occupant behavior significantly contributes to the total energy use in buildings and its understanding is greatly needed in energy analysis/simulation studies. Uncertainties about the occupant behavior adversely affect ... -
Quantifying savings in spaces energy demands and CO2 emissions by shading and lighting controls in the Arabian Gulf
( Elsevier Ltd , 2018 , Article)Despite the deceleration in worldwide annual energy consumption and CO2 emissions, many countries, such as in the Arabian Gulf, are still unarguably far from following this international trend. This study investigates the ... -
Induced bioelectrochemical metabolism for bioremediation of petroleum refinery wastewater: Optimization of applied potential and flow of wastewater
( Elsevier Ltd , 2018 , Article)Hybrid based bioelectrochemical system (BES) configured with embedded anode and cathode electrodes in soil was tested for the bioelectrochemical degradation of petroleum refinery wastewater (PRW). Four applied potentials ... -
Methods and Techniques Used in Significant Restoration Projects in Qatar
( Taylor and Francis Ltd. , 2018 , Article)The large number of conservation and restoration works recently completed in Qatar show that there exists a need to enhance appreciation of the local architectural and building traditions, as a way of bringing to light the ... -
Numerical study of the attenuation properties of viscoelastic metamaterials
( Institute of Physics Publishing , 2018 , Conference Paper)Metamaterials (MMs) are materials engineered to have a property that is not found in nature. In this study, one-dimensional MMs is investigated, particularly that with a functional elastic wave band gaps where propagation ... -
Performance assessment of evaporatively-cooled window driven by solar chimney in hot and humid climates
( Elsevier Ltd , 2018 , Article)This study investigates the application of the evaporatively-cooled window system in hot and humid climates and assesses its seasonal performance and benefits in terms of energy savings. The validated system is a hybrid ... -
Experimental study of the attenuation properties of metal-viscoelastic bi-layered materials
( Institute of Physics Publishing , 2018 , Conference Paper)Phononic crystals (PCs) are multi-layered materials with functional elastic wave band gaps where propagation of vibration within these band gaps is restricted. PCs have vibration attenuation properties dependent on their ... -
Numerical study on the effect of insulator size and shape on fouling suppression by electrodeless dielectrophoresis in submerged membrane bioreactors
( American Institute of Physics Inc. , 2018 , Conference Paper)The application of obstacle dielectrophoresis has the potential to enhance membrane fouling suppression in submerged membranes bioreactors while requiring low energy consumption. In this study, the effect of the insulators ... -
