Heat enhanced follicular delivery of isotretinoin to the skin
(2019-08-01)Purpose: The aim of this work was to evaluate the use of short durations of externally applied heat with chemical penetration enhancers to improve delivery of isotretinoin to the skin and in particular via the follicular ... -
Heat production and oxygen consumption during metabolic recovery of white muscle fibres from the dogfish Scyliorhinus canicula
(2000-04)Oxygen consumption and heat production were measured during contraction and recovery of isolated, white muscle fibres from dogfish (Scyliorhinus canicula) at 19 degrees C. The contraction period consisted of 20 isometric ... -
Heat transfer analysis for phase change materials (PCMs)
(2009)The heat transfer enhancement for phase change materials (PCMs) has received much attention nowadays, since most of PCMs have low thermal conductivities which prolong the charging and discharging processes. Metal foams, ... -
Heat transfer correlations and pressure drop dynamics of palm fibre wetting media for evaporative cooling at different air flow rates
(2023-10-03)The thermal and flow resistance properties of wetting pads play a key role in how effective direct evaporative cooling (DEC) systems Perform. To make an informed decision, it's crucial to study the heat transfer properties ... -
Heat transfer enhancement for thermal energy storage using metal foams embedded within phase change materials (PCMs)
(2010-08)In this paper the experimental investigation on the solid/liquid phase change (melting and solidification) processes have been carried out. Paraffin wax RT58 is used as phase change material (PCM), in which metal foams are ... -
Heat-maps and visualization for heterogeneous biomedical data based on information distance geometry
(Springer Nature, 2012)Systems biology is very much concerned with gaining an overview of what is happening in complex systems, such as in biomedical data sets, for which we need good global visualization tools. This research uses a method based ... -
Heavy elements and age determinations
(2002-01)The age of the universe, measured from the Big Bang to the present, is at the focus of cosmology. Its determination relies, however, on the use of stellar objects or their products. Stellar explosions, like type Ia supernovae ... -

Heavy elements nucleosynthesis on accreting white dwarfs : Building seeds for the p-process
(2020-10-01)The origin of the proton-rich trans-iron isotopes in the Solar system is still uncertain. Single-degenerate thermonuclear supernovae (SNIa) with n-capture nucleosynthesis seeds assembled in the external layers of the ... -
The Hebb repetition effect as a laboratory analogue of novel word learning
(2009)The present study tests the hypothesis that a common ordering mechanism underlies both short-term serial recall of verbal materials and the acquisition of novel long-term lexical representations, using the Hebb repetition ... -
Hedgehog Signalling in Androgen Independent Prostate Cancer
(2008-12-01)Objectives: Androgen-deprivation therapy effectively shrinks hormone-naïve prostate cancer, both in the prostate and at sites of distant metastasis. However prolonged androgen deprivation generally results in relapse and ... -
Hedonic Quality or Reward? A Study of Basic Pleasure in Homeostasis and Decision Making of a Motivated Autonomous Robot
(2016-10-12)We present a robot architecture and experiments to investigate some of the roles that pleasure plays in the decision making (action selection) process of an autonomous robot that must survive in its environment. We have ... -
Hedonic Value : Enhancing Adaptation for Motivated Agents
(2013)Reinforcement learning (RL) in the context of artificial agents is typically used to produce behavioural responses as a function of the reward obtained by interaction with the environment. When the problem consists of ... -
Hegel on Purpose
(2019-08-29)In this paper we propose a new interpretation of Hegel’s views on action and responsibility, defending it against its most plausible exegetical competitors. Any exposition of Hegel will face both terminological and substantive ... -
Helical axis analysis to quantify humeral kinematics during shoulder rotation.
(2019-04-01)Information pertaining to the helical axis during humeral kinematics during shoulder rotation may be of benefit to better understand conditions such as shoulder instability. The aim of this study is to quantify the behavior ... -
Helicopter EMS and rapid transport for ST-elevation myocardial infarction: The HEARTS study
(2017-09-19)Background: Helicopter emergency medical services (HEMS) and ground EMS (GEMS) are both integral parts of out-of-hospital transport systems for patients with ST-elevation myocardial infarction (STEMI) undergoing emergency ... -
Helium absorption and emission towards Theta^1 ORI C
(1997)The Hei absorption and emission systems towards Theta^1Ori C, the exciting star of the Orion Nebula, are investigated. To this end, high-resolution near-infrared long-slit spectra centred on the Hei 1.083-μm and Brgamma ...
