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 ... -
Reducing the incidence of exposure to blood and body fluids
( Qatar University Press , 2020 , Poster)Methods: we used a Pareto chart to identify priority areas for our project based on magnitude of incidence of BBF exposures. A driver diagram was developed with four main primary drivers including risk awareness, attitudes ... -
Reducing the number of rebooking of urgent in-person visits in general paediatric ambulatory clinics during the COVID-19 pandemic
( Hamad bin Khalifa University Press (HBKU Press) , 2022 , Article)Background: Due to the COVID-19 pandemic, all out-patients clinics shifted to telehealth visits 1 . However some patients still needed to be seen as face to face visit 2 , mostly through the new urgent referrals which were ... -
A Reduction in Maximal Incremental Exercise Test Duration 48 h Post Downhill Run Is Associated with Muscle Damage Derived Exercise Induced Pain.
( Frontiers Media , 2017 , Article)Purpose: To examine whether exercise induced muscle damage (EIMD) and muscle soreness reduce treadmill maximal incremental exercise (MIE) test duration, and true maximal physiological performance as a consequence of exercise ... -
Reduction in piezoelectric voltage generation for the cerium doped nickel ferrite nanoparticles filled PVDF-HFP nanocomposites
( Elsevier B.V. , 2019 , Article)This paper describes the synthesis of grape cluster shaped nickel ferrite (NiFe 2 O 4 ) and cerium doped nickel ferrite (Ce-NiFe 2 O 4 ) nanoparticles by chemical co-precipitation and their addition to poly(vinylidene ... -
Reduction kinetics of ceria surface by hydrogen
( Wiley Periodicals, Inc. , 2004 , Article)Powdered cerium dioxide (ceria, CeO2) as compressed, sintered pellets, of porosity 16.4% and density 5.99 g cm?3, were treated in hydrogen flow at 1 atm and various temperatures to effect reduction. The electrical conductivity ... -
Reduction kinetics of ceria surface by hydrogen
( Elsevier , 2004 , Article)Sintered ceria pellets of porosity 16.4% and density 5.99gcm−3 were treated in a hydrogen flow at 1atm and various temperatures. The electrical conductivity was measured in situ while hydrogen gas was flowing over the CeO2. ... -
Reed-Solomon coding for cooperative wireless communication
( IEEE , 2010 , Conference Paper)During the last few years, several authors have studied the performance of many different types of channel codes for cooperative communication systems. Some of these codes include Low Density Parity Check (LDPC), Turbo and ... -
Reference Layer Artefact Subtraction (RLAS): Electromagnetic Simulations
( Institute of Electrical and Electronics Engineers Inc. , 2019 , Article)The utility of EEG-fMRI is limited by the large artefact voltages produced in EEG recordings made during concurrent fMRI. Novel approaches for reducing the magnitude and variability of the artefacts are, therefore, required. ... -
Reference ranges of lymphocyte subsets in healthy Qatari adults
( Future Medicine Ltd , 2015 , Article)Aim: Determine reference ranges of lymphocyte subsets in healthy Qatari adults. Patients & Methods: Blood samples (n = 150) were investigated using four colors flow cytometery. Results: The mean percentage and absolute ... -
Reference Walking Speeds for Healthy Young Adults in Qatar: Moderating Effect of Obesity and Physical Activity
( SAGE , 2022 , Article)Walking speed (WS) is considered an important indicator for overall health. Despite this, there is a paucity of data relating to WS values in the Arab region. The present study aims to establish preferred (PWS) and maximal ... -
Refinancing the Rentier State: Welfare, Inequality, and Citizen Preferences toward Fiscal Reform in the Gulf Oil Monarchies
( City University of New York , 2021 , Article)Against the backdrop of fiscal reform efforts in Middle East oil producers, this article proposes a general framework for understanding how citizens relate to welfare benefits in the rentier state and then tests some ... -
Refined Inference on the Scale Parameter of the Generalized Logistic Distribution Based on Adjusted Profile Likelihood Functions
( MDPI , 2022 , Article)We consider inference based on the profile likelihood function for the scale parameter of the generalized logistic distribution. This distribution is a generalization of the logistic distribution, a symmetric distribution ... -
Refining the ambiguity domain characteristics of non-stationary signals for improved time–frequency analysis: Test case of multidirectional and multicomponent piecewise LFM and HFM signals
( Elsevier Inc. , 2018 , Article)This paper aims at providing a more accurate description of the ambiguity domain characteristics of a piecewise multicomponent non-stationary signals with focus on piece-wise linear frequency modulated (LFM) (PW-LFM) signal ... -
Reflectance spectroscopy and ASTER mapping of aeolian dunes of Shaqra and Tharmada Provinces, Saudi Arabia: Field validation and laboratory confirmation
( Taylor and Francis Group , 2022 , Article)Spatial variability of grain sizes and mapping of aeolian dunes is important to study the sand erosion, transport, and dune movement and to understand the dune encroachment and land degradation. This study examines the ... -
Reflections of scientific literacy team members related to use of reading strategies
( Hamad bin Khalifa University Press (HBKU Press) , 2015 , Conference Paper)The efficacy of reflection in improving teaching practices has long been recognized.
