A Study on Using Reclaimed Asphalt Pavement (RAP) in the Construction of New Roads in the State of Qatar
( Qatar Univesrity Press , 2020 , Conference Paper)In the State of Qatar, road engineers started using RAP in the base course of asphalt pavement from past few years. The use of RAP not only replaces the quantity of virgin aggregate and binder, it also improves the overall ... -
Applications of chelating agents in the upstream oil and gas industry: A review
( American Chemical Society , 2020 , Article Review)Chelating agents show very effective performance in different applications in the upstream oil and gas industry. This study presents a critical review of the application of chelating agents in acidizing, scale removal, ... -
Cryogenic temperature and strain rate dependence of mechanical properties for extruded AA6060 alloys
( Trans Tech Publications Ltd , 2014 , Article)Tensile properties and fracture behavior of an AA6060 alloy were investigated at room temperature (295K) and cryogenic temperature (77K). It was found that both ultimate tensile strength and elongation increased with ... -
Effect of multi-pass friction stir processing on the microstructure, mechanical and wear properties of AA5083/ZrO2 nanocomposites
( Elsevier Ltd , 2017 , Article)In this study, multi-pass friction stir processing using zirconia nanoparticles was performed on AA5083 sheets to fabricate surface nanocomposites. Effect of using different number of passes on the microstructure, ... -
Exposure to Chinese Famine during Early Life Increases the Risk of Fracture during Adulthood
( MDPI , 2022 , Article)This study focused on identifying whether exposure to the Chinese Great Famine (1959–1961) in early life amplified the potential for fractures in adulthood. The survey was conducted using data from the 1997–2015 China ... -
Increased Fracture Risk After Bariatric Surgery: a Case-Controlled Study with a Long-Term Follow-Up
( Springer , 2021 , Article)Purpose: Bariatric surgeries are common procedures due to the high prevalence of obesity. This study aimed to investigate whether bariatric surgery increases fracture risk. Material and Methods: It was a case-controlled ... -
Investigation of the mechanical behavior of electroless Ni-P-Ti composite coatings
( American Society of Mechanical Engineers (ASME) , 2020 , Article)To improve the toughness of Ni-P coatings, NiTi superelastic particles were introduced into the Ni-P matrix through the electroless co-depositing of Ni-P and Ti particles and annealing Ni-P-Ti coatings. The mechanical ... -
Loss circulation in drilling and well construction: The significance of applications of crosslinked polymers in wellbore strengthening: A review
( Elsevier B.V. , 2020 , Article Review)Loss circulation is one of the major concerns in drilling and well construction. The uncontrolled flow of fluids into formation while drilling or primary cementing lead to substantial non-productive time (NPT). The methods ... -
Modelling Catchments in Qatar to Assist in Operations
( Qatar Univesrity Press , 2020 , Conference Paper)Qatar is experiencing unprecedented growth and infrastructure is being developed at a rapid pace. The infrastructure is served by storm water systems which are under development and need to be resilient in case of storms. ... -
Non-steroidal anti-inflammatory drugs and bone healing in animal models-a systematic review and meta-analysis
( BMC , 2021 , Article)Background: Non-steroidal anti-inflammatory drugs (NSAID) have excellent anti-inflammatory and analgesic properties and are extensively used to treat post-traumatic or surgical musculoskeletal pain. Although an extensive ... -
Numerical simulation of the fracture and compression response of self-healing concrete containing engineered aggregates
( Elsevier , 2023 , Article)The existing self-healing concretes that rely on capsules require modifications to one or more traditional concrete mixing, placing, and consolidating methods. Additionally, concrete mixture designs need alterations to ... -
Pathological fracture of mandible associated with an asymptomatic cholesterol granuloma
( Elsevier , 2021 , Report)Cholesterol granuloma is a rare lesion in the maxillofacial and is often associated with benign cysts or tumors. It is caused by reaction to the foreign body and inadequate drainage of cholesterol crystals. We report here ... -
Sensing Temperature and Stress Distributions on Rock Samples under Mechanical Loading
( American Society of Civil Engineers (ASCE) , 2016 , Conference Paper)In the exploration of planetary materials using robotic probes, one of the key priorities is to establish fundamental level understandings on the mechanical response of materials under different levels of loading. In this ... -
Thermal behavior and post-heating fracture characteristics of polypropylene microfiber-reinforced geopolymer binders
( Elsevier , 2022 , Article)This paper investigated the post-heating behavior of fly ash-based geopolymer binders reinforced with polypropylene (PP) microfibers. Geopolymer binders with different fiber contents including 0%, 0.05%, 0.1%, and 0.2% by ...
