Flow and Fracture Behaviour of Tungsten Fiber Reinforced Superalloy Composites-Effect Of Specimen Geometry
( Qatar University , 1989 , Article)The influence of aspect ratio (i.e. width to height ratio) of test specimens on the flow and fracture behaviour of fiber reinforced composites is herein examined. The composite material was prepared by isostatic pressing ... -
Flow and heat transfer analysis of Jeffery nano fluid impinging obliquely over a stretched plate
( Taiwan Institute of Chemical Engineers , 2017 , Article)This study investigates the problem of oblique stagnation point flow using Jeffery nanofluid as a rheological fluid model. Effects of thermophoresis and Brownian motion are taken into account. The governing nonlinear partial ... -
Flow induced vibrations of pressure let-down station in QATARGAS
(2006 , Conference Paper)The use of the pipes to transfer oil and gases from production to export places is a common application in oil and gas industries. The safety and stability of the pipelines are crucial to prevent human and equipment losses. ... -
Flow injection potentiometric determination of harmine and harmaline hallucinogens
( Wiley-VCH Verlag , 1995 , Article)Flow injection analysis (FIA) systems incorporating potentiometric sensors for harmine and harmaline hallucinogens are described. The sensors are based on the use of harmine and harmaline tetraphenylborate or reineckate ... -
Flow mapping of multiphase flows using a novel single stem endoscopic particle image velocimetry instrument
( Institute of Physics Publishing , 2011 , Conference Paper)Particle image velocimetry (PIV) is a successful flow mapping technique which can optically quantify large portions of a flow regime. This enables the method to be completely non-intrusive. The ability to be non-intrusive ... -
Flow of Activities: Utilizing Parade of Trade to Develop Visual Management Tool Tailored for Infrastructure Projects
( Qatar University Press , 2023 , Conference Paper)Parade of Trade (PoT) is a game used in Lean Construction to demonstrate the impact of variability on a production system and to promote the value of constraint management in an environment of dependent events. Infrastructure ... -
Flow Routing Calculations For Water Resources Management Using Spreadsheets
( Qatar University , 1999 , Article)Flow routing calculations are very important for water resources engineers for analyzing and designing water engineering systems such as reservoirs, stocmwater conduits and detention ponds, spillways, pumping stations, ... -
Flow-based intrusion detection algorithm for supervisory control and data acquisition systems: A real-time approach
( John Wiley and Sons Inc , 2021 , Article)Intrusion detection in supervisory control and data acquisition (SCADA) systems is integral because of the critical roles of these systems in industries. However, available approaches in the literature lack representative ... -
Fluctuations in cardiac stroke volume during rowing
( Blackwell Munksgaard , 2021 , Article)Preload to the heart may be limited during rowing because both blood pressure and central venous pressure increase when force is applied to the oar. Considering that only the recovery phase of the rowing stroke allows for ... -
Fluid Flow Characteristics of Healthy and Calcified Aortic Valves Using Three-Dimensional Lagrangian Coherent Structures Analysis
( MDPI , 2021 , Article)Aortic valve calcification is an important cardiovascular disorder that deteriorates the accurate functioning of the valve leaflets. The increasing stiffness due to the calcification prevents the complete closure of the ... -
Fluid-rock interactions in tight gas reservoirs: Wettability, pore structural alteration, and associated multiphysics transport
( Elsevier , 2023 , Book chapter)Tight and unconventional reservoirs such as shales are rich in clay minerals that give rise to several fluid-rock interactions. The effect of such fluid-rock interactions is manifested at multiscales. The fluid-rock ... -
Fluometuron Induced Growth, Chemical And Photosynthetic Changes In Chlorella Vulgaris
( Qatar University , 1988 , Article)Presence of fluometuron at different concentrations in the culture medium of Chlorella vulgaris induced pronounced inhibition in the growth rate and dry weight of the alga throughout the experimental period. Furthermore, ... -
A fluorescence-based polymerase chain reaction-linked single-strand conformation polymorphism (F-PCR-SSCP) assay for the identification of Fasciola spp
( Springer Verlag , 2011 , Article)The present study aimed to establish a fluorescence-based polymerase chain reaction-linked single-strand conformation polymorphism (F-PCR-SSCP) assay for the identification of Fasciola spp. Based on the sequences of the ... -
Fluorescent Zn(II)-Based Metal-Organic Framework: Interaction with Organic Solvents and CO<inf>2</inf> and Methane Capture
( MDPI , 2022 , Article)Adsorption of carbon dioxide (CO2), as well as many other kinds of small molecules, is of importance for industrial and sensing applications. Metal-organic framework (MOF)-based adsorbents are spotlighted for such applications. ... -
