Effect of forging on the low cycle fatigue behavior of cast AZ31B Alloy
(Elsevier, 2017-08-26)The effect of forging on the low cycle fatigue (LCF) behavior of cast AZ31B was investigated. The forging process was conducted at a temperature of 450°C and speed of 390mm/min. Fully reversed (Rε=-1) strain controlled ... -
The effect of hematocrit on solid-phase microextraction
(Elsevier, 2018-02-25)Solid-phase microextraction (SPME) is an approach to sample preparation that has demonstrated its appropriateness for isolating/enriching analytes present in complex biofluids with minimum sample pre-treatment. Several ... -
Effect of hemin, baicalein and heme oxygenase-1 (HO-1) enzyme activity inhibitors on Cd-induced accumulation of HO-1, HSPs and aggresome-like structures in Xenopus kidney epithelial cells
(Elsevier, 2018-08-01)Cadmium is a highly toxic environmental pollutant that can cause many adverse effects including cancer, neurological disease and kidney damage. Aquatic amphibians are particularly susceptible to this toxicant as it was ... -
Effect of heterophoria type and myopia on accommodative and vergence responses during sustained near activity in children
(Elsevier, 2012-03-15)The influence of phoria-type and myopia on changes to vergence and accommodation during prolonged near-task was examined in 53 children. Participants were classified into phoria and refractive categories based on near ... -
The effect of hydrogen peroxide produced during ultraviolet disinfection of CHO cell culture media
(Elsevier, 2017-10-01)Ultraviolet (UV) irradiation is being considered for protection against viral contamination in cell culture media. Hydrogen peroxide (H2O2) produced by UV irradiation has been suggested as the cause for poor cell growth ... -
The Effect of Input Signals Time-Delay on Stabilizing Traffic with Autonomous Vehicles
(IEEE, 2021-05)This paper extends the results in [1] considering time delays in Standard Car Following models (CFMs). In [1], connected vehicles are characterized with CFMs models and controlled using linear string analysis to stabilize ... -
The effect of interior bezel presence and width on magnitude judgement
(Canadian Human-Computer Communications Society, 2014-05)Large displays are often constructed by tiling multiple small displays, creating visual discontinuities from inner bezels that may affect human perception of data. Our work investigates how bezels impact magnitude judgement, ... -
Effect of isothiocyanates, BITC and PEITC, on stress protein accumulation, protein aggregation and aggresome-like structure formation in Xenopus A6 kidney epithelial cells
(Elsevier, 2018-01-01)Numerous studies have elucidated the health benefits of organosulfur compounds, known as isothiocyanates (ITCs), derived from cruciferous vegetables. As electrophiles, ITCs have the ability to directly bind and modify ... -
Effect of Nanoscopic Particles on the Mesophase Structure of Diblock Copolymers
(American Chemical Society, 2002)Introduction. The fabrication of novel biomimetic photonic and electronic materials requires the manipulation of both organic and inorganic materials at the nanometer length scale. One possible means of achieving this level ... -
Effect of near adds on the variability of accommodative response in myopic children
(Wiley, 2011-03)Purpose: Higher variability of accommodative response (VAR) has been reported in myopes and speculated to be a possible risk factor for the progression of myopia. We investigated whether near adds of +2D and −2D were capable ... -
The effect of non-spherical platinum nanoparticle sizes on the performance and durability of proton exchange membrane fuel cells
(Elsevier, 2021-11)Platinum (Pt) nanoparticles with different sizes of 2 nm and 5 nm supported on functionalized high surface area carbon (HSC) have been successfully synthesized with a one-pot synthesis technique in large scale. Of the ... -
Effect of obesity on knee joint biomechanics during gait in young adults
(Taylor & Francis, 2016-04-26)While there are many comorbidities associated with obesity, one of the more poorly understood is knee osteoarthritis through obesity. The purpose of this study was to compare the kinematics and kinetics of gait and cumulative ... -
The effect of omitted covariates in marginal and partially conditional recurrent event analyses
(Springer, 2019-04-01)There have been many advances in statistical methodology for the analysis of recurrent event data in recent years. Multiplicative semiparametric rate-based models are widely used in clinical trials, as are more general ... -
The effect of peat structure on the spatial distribution of biogenic gases within bogs: EFFECT OF PEAT STRUCTURE ON BIOGENIC GAS
(Wiley, 2014-10-30)Northern peatlands are a large source of atmospheric methane (CH4) and both a source and a sink of atmospheric carbon dioxide (CO2). The rate and temporal variability in gas exchanges with peat soils is directly related ... -
Effect of Plant Functional Type on Methane Dynamics in a Restored Minerotrophic Peatland
(Springer, 2017-01)Background and Aims: Peatland methane (CH4) fluxes may vary between plant types; however, in mixed communities, the specific role of each species is difficult to distinguish. The goal of this study was to determine the ... -
The effect of portable HEPA filter air cleaners on indoor PM2.5 concentrations and second hand tobacco smoke exposure among pregnant women in Ulaanbaatar, Mongolia: The UGAAR randomized controlled trial
(Elsevier, 2018-02-15)Background Portable HEPA filter air cleaners can reduce indoor fine particulate matter (PM2.5), but their use has not been adequately evaluated in high pollution settings. We assessed air cleaner effectiveness in reducing ... -
