Establishing the importance of oil-membrane interactions on the transmembrane diffusion of physicochemically diverse compounds
(2016-06-15)The diffusion process through a non-porous barrier membrane depends on the properties of the drug, vehicle and membrane. The aim of the current study was to investigate whether a series of oily vehicles might have the ... -
Establishing the values for patient engagement (PE) in health-related quality of life (HRQoL) research: an international, multiple-stakeholder perspective
(2016-12-08)PurposeActive patient engagement is increasingly viewed as essential to ensuring that patient-driven perspectives are considered throughout the research process. However, guidance for patient engagement (PE) in HRQoL ... -
Establishment and impact of Pseudomonas fluorescens genetically modified for lactose utilization and kanamycin resistance in the rhizosphere of pea
(1998)The impact of a Pseudomonas fluorescens strain, genetically modified for kanamycin resistance and lactose utilisation (the GMM), could be enhanced by soil amendment with lactose and kanamycin. Lactose addition decreased ... -
Estimating energy expenditure by heart-rate monitoring without individual calibration
(2001)Heart rate monitoring has been shown to be a valid method for measuring free-living energy expenditure at the group level, but its use in large-scale studies is limited by the need for an individual calibration of the ... -
Estimating Invariant Principal Components Using Diagonal Regression
(University of Hertfordshire, 2005)In this work we apply the method of diagonal regression to derive an alternative version of Principal Component Analysis (PCA). Diagonal regression was introduced by Ragnar Frisch (the first economics Nobel laureate) in ... -
Estimating meteor rates using Bayesian inference
(2011-10)A method for estimating the true meteor rate lambda from a small number of observed meteors n is derived. We employ Bayesian inference with a Poissonian likelihood function. We discuss the choice of a suitable prior and ... -
Estimating size in incremental software development projects
(2005-12)The motivation for this work is derived from the current interest in speeding up development schedules. A key implication of the shift to more rapid development methods is the growing emphasis on fixed time and fixed effort ... -
Estimating sizes of faint, distant galaxies in the submillimetre regime
(2016-10-21)We measure the sizes of redshift ˜2 star-forming galaxies by stacking data from the Atacama Large Millimeter/submillimeter Array (ALMA). We use a uv-stacking algorithm in combination with model fitting in the uv-domain and ... -
Estimating the diffusive heat flux across a stable interface forced by convective motions
(2010)Entrainment at the top of the convectively-driven boundary layer (CBL) is revisited using data from a high-resolution large-eddy simulation (LES). In the range of values of the bulk Richardson number RiB studied here (about ... -
Estimating the low-mass IMF in OB associations : o Orionis
(Springer Nature, 2005)We investigate the issues of contamination and exclusion in photometric membership selection techniques when applied to OB associations. We use radial velocities to calculate membership probabilities for a sample of very ... -
Estimating the Number of Local Maxima for k-SAT Instances
(2008)We explore the applicability of a sampling method devised by J. Garnier and L. Kallel (SIAM J. Discrete Math., 2002) to approximate the number of local maxima in search spaces induced by k-SAT instances and a simple ... -
Estimating the star formation rate at 1 kpc scales in nearby galaxies.
(2012-07)Using combinations of H alpha, ultraviolet (UV), and infrared (IR) emission, we estimate the star formation rate (SFR) surface density, Sigma(SFR), at 1 kpc resolution for 30 disk galaxies that are targets of the IRAM ... -
Estimating under-reporting of energy intake in dietary surveys using an individualised method
(2007)Under-reporting (UR) of energy intake (EI) by self-reported dietary methods is well-documented but the methods used to estimate UR in population-based studies commonly assume a sedentary lifestyle. We compared estimated ... -
Estimating Willingness to Pay Air Passenger Duty
(2018-09-01)Carbon taxation on air travellers is widely considered an effective way of offsetting environmental externalities and adjusting tourist flow. Despite the popularity of carbon taxation, research investigating travellers’ ... -
Estimation and Comparison of Endogenous Ordered Category Multilevel Models
(University of Hertfordshire, 2004)Data often take the form of ordered categories. For instance, in education, test results are often reported as grades. Where a hierarchical structure exists for--the data, multilevel modelling of such ordered categorisations ... -
Estimation and comparison of endogenous ordered category multilevel models
