Two Strategies to Enhance Ungual Drug Permeation from UV-cured Films: Incomplete Polymerisation to Increase Drug Release and Incorporation of Chemical Enhancers
(2018-10-15)UV-curable gels, which polymerise into long-lasting films upon exposure to UVA, have been identified as potential topical drug carriers for the treatment of nail diseases. Limitations of such films include incomplete drug ... -
Two super-earths orbiting the solar analog HD 41248 on the edge of a 7 : 5 mean motion resonance
(2013-07-01)There are a growing number of multi-planet systems known to be orbiting their host stars with orbital periods that place them in mean motion resonances (MMRs). These systems are generally in first-order resonances and ... -
Two types of calcium channels in single smooth muscle cells from rabbit ear artery - studied with whole cell and single channel recordings
(1987)AB Freshly dispersed rabbit ear artery cells were studied using patch-clamp techniques to measure membrane currents in whole cells and single-channel currents in membrane patches. Whole-cell calcium currents recorded at ... -
Two UK suicides using nicotine extracted from tobacco employing instructions available on the Internet
(2010)Tobacco is one of the most easily accessible and commonly abused drugs world-wide. Nicotine, one of its principal constituents, can cause serious or fatal overdoses. Whilst the deliberate ingestion of this substance appears ... -
Two weather-based models for predicting the onset of seasonal release of ascospores of Leptosphaeria maculans or L-biglobosa
(2007-06)Weather-based models (Improved Blackleg Sporacle and SporacleEzy) to predict the date of onset of seasonal release from oilseed rape debris of ascospores of Leptosphaeria maculans or L. biglobosa, causes of phoma stem ... -
Two Wittgensteins too many: Wittgenstein's foundationalism
(Ashgate Publishing, 2004)In his contribution to this volume, Avrum Stroll makes the assertion that there is ‘a feature of [Wittgenstein's] later philosophy that occurs only in On Certainty. This is a unique form of foundationalism that is neither ... -
Two-component models are of limited value for the assessment of body composition in patients with cirrhosis
(2006)Most techniques for measuring body composition are based on 2-component models (2-CMs) and depend on assumptions relating to the constancy of the density (D(FFM)) and hydration fraction (HF(FFM)) of fat-free mass (FFM). -
A Two-dimensional Analytical Model for Prediction of the Radiation Heat Transfer in Open-cell Metal Foams
(2016-01-25)In this article, a new two-dimensional (2D) explicit analytical model for the evaluation of the radiation heat transfer in highly porous open-cell metal foams is formulated and validated. A correction factor, C, is introduced ... -
A Two-dimensional Frying Model for the Investigation and Optimisation of Continuous Industrial Frying System
(2013-03-01)In this study, a coupled two-dimensional transient model was developed to predict the temperature, moisture content and oil uptake as encountered in industrial continuous deep fryers. The set of transient governing equations ... -
A two-dimensional search for a Gauss-Newton algorithm
(2009)This paper describes a fall-back procedure for use with the Gauss-Newton method for nonlinear least-squares problems. While the basic Gauss-Newton algorithm is often successful, it is well-known that it can sometimes ... -
A Two-dimensional Search used with a Non-Linear least Squares Solver
(2000)This note describes a modified search strategy for use with a Gauss-Newton method for nonlinear least-squares problems. If a standard line search along the Gauss-Newton vector p is unable to make much progress, a new search ... -
A Two-dimensional Splashing Model for Investigating Impingement Characteristics of Supercooled Large Droplets
(2016-04-01)In this article, a two-dimensional (2D) splashing model is proposed to investigate the dynamics when supercooled large droplets (SLD) impinging on a wall surface in the aircraft-icing field. Energy conservation for droplet ... -
Two-level branch prediction using neural networks
(2003)Dynamic branch prediction in high-performance processors is a specific instance of a general time series prediction problem that occurs in many areas of science. Most branch prediction research focuses on two-level adaptive ... -
Two-Level Reinforcement Learning Framework for Self-Sustained Personal Robots
(Springer Nature, 2023-12-03)As social robots become integral to daily life, effective battery management and personalized user interactions are crucial. We employed Q-learning with the Miro-E robot for balancing self-sustained energy management and ... -
A two-phase qualitative enquiry into storytelling’s potential to support palliative care patient-led change, using a systematic review approach
(2024-01-09)A terminal diagnosis can diminish an individual’s sense of agency and identity. Leading change appears to restore a sense of agential self. The first phase of this literature review explores factors influencing patient-led ... -
A two-stage approach of manufacturing FeAl40 iron aluminides by self-propagating synthesis and pressureless sintering
(2018-08-08)A two-stage sintering process was successfully used to sinter FeAl to densification levels of just above 95% at a temperature of 1300 ºC. In the first stage, mixed iron and aluminium powders were synthesised at 750°C via ... -
Type Ia supernova progenitors, lifetime, and cosmic supernova rate
(Springer Nature, 2003)We make a comparison of the lifetime distribution derived from several models of Type Ia Supernovae (SNe Ia) and evaluate the SN Ia models from the observational constraints. Our SN Ia model, which is based on the single ...
