A preliminary study of the effect of hyaluronan on the deposition of C-14-labelled diclofenac within human skin using autoradiography
(Royal Society of Medicine Press, 1995) -
A preliminary survey of aerial biocontaminants at six London Underground Stations
(1998-03-01)Six London Underground stations and one above ground site were sampled for the bacteria and fungal air spora over a two month period. Results were analysed for counts at different sites and times. Whilst time was found not ... -
Preparation and characterisation of natamycin : gamma-cyclodextrin inclusion complex and its evaluation in vaginal mucoadhesive formulations
(2008)Novel formulations of vaginal bioadhesive tablets were prepared where the natamycin was complexed with gamma-cyclodextrin (NT-gamma CyD) to increase the solubility and stability of NT in aqueous solutions and reduce the ... -
Preparation and characterization of 33S samples for 33S(n,α)30Si cross-section measurements at the n_TOF facility at CERN
(2018-05-11)Thin 33S samples for the study of the 33S(n,α)30Si cross-section at the n_TOF facility at CERN were made by thermal evaporation of 33S powder onto a dedicated substrate made of kapton covered with thin layers of copper, ... -
Preparation and evaluation of the in vitro drug release properties and mucoadhesion of novel microspheres of hyaluronic acid and chitosan
(2000-05-15)Rapid mucociliary clearance of intranasally administered drugs is often a key factor in determining the bioavailability of such therapeutic agents. The use of mucoadhesive microparticles provide a potential strategy for ... -
The preparation and execution of saccadic eye and goal directed hand movements in patients with Parkinson's disease
(2001)The oculomotor and manual motor systems were studied in a two-segment movement task in a group of patients with Parkinson's disease and in age matched normal controls. In order to avoid reflexive motor movements the selection ... -
Preparation and microstructure of AlOTiC composites by self-propagated high temperature synthesis
(1994-01-04)This investigation was concerned with the production of ceramic composites based on AlOTiC by means of self-propagated high temperature synthesis. When titanium and carbon black mixed with AlO powder reacted, the ignition ... -
Preparation and polymeric encapsulation of powder mineral pellets for self-healing cement based materials
(2018-10-20)Using mineral additives and admixtures as self-healing agents in cement-based composites has been extensively researched. However, if the minerals are added directly to the cementitious matrix without any protection, they ... -
Preparation and Properties of Graphene Doped TiO2 Mesoporous Materials for Photocathode Protection
(2021-01-31)In this study, TiO2-Graphene nanocomposites with a pore size of 10-15 nm were prepared by a sol-gel method under ultrasonic radiation environment. This kind of TiO2-Graphene nanocomposites show excellent performance in the ... -
Preparation and thermophysical characterisation analysis of potential nano-phase transition materials for thermal energy storage applications
(2023-04-15)The efficacious use of phase change materials (PCMs) is mainly confined by their poor thermal conductivity (TC). In this study, multiwalled carbon nanotubes (MWCNTs), graphene nanoplatelets (GNP) and titanium oxide (TiO2) ... -
The preparation and tribological properties of surface modified zinc borate ultrafine powder as a lubricant additive in liquid paraffin
(2014-02-01)This paper investigates the effects of surface modification of zinc borate ultrafine powders (ZB UFPs) on their tribological properties as lubricant additives in liquid paraffin (LP). ZB UFPs were successfully modified by ... -
Preparation for the Novel Crisis: A Curriculum and Pedagogy for Emergent Crisis Leadership
(2018-09-10)The context for this study is the convergence of global trends and risks, especially environmental and social changes, with the interconnectedness of the modern world leading to new, larger-scale, and unforeseeable crises. ... -
Preparation of ceramic composite powders from waste colliery minestones
(1994-03-01)An investigation was carried out to examine the potential for producing ceramic composites from waste colliery minestones. The nature of the raw materials had a marked influence on the kinetics and the product morphology. ... -
Preparation of Fe-TiC composites by the thermal-explosion mode of combustion synthesis
(1997-01-01)Titanium carbide ferrous matrix composites were produced by means of the thermal explosion mode of combustion synthesis. The combusting behaviour of the powder mixtures was investigated. The effect of the processing variables ... -
Preparation of N-doped carbon dots based on starch and their application in white LED
(2018-12-01)N-doped carbon dots (CDs) were synthesized simply and economically by a one-step hydrothermal method using starch as a carbon source and ethylenediamine (EDA) as a nitrogen dopant. The prepared CDs possess the properties ... -
Preparatory work to support the re-evaluation of botanically defined feed flavouring additives
(European Food Safety Authority (EFSA), 2015-02-13)In recent years, interest in the use of naturally occurring substances of botanical origin as livestock feed additives has increased significantly. Before any additive can be marketed it must undergo a rigorous scientific ... -
Preparing for low surface brightness science with the Vera C. Rubin Observatory: Characterisation of tidal features from mock images
(2022-06-01)Tidal features in the outskirts of galaxies yield unique information about their past interactions and are a key prediction of the hierarchical structure formation paradigm. The Vera C. Rubin Observatory is poised to deliver ... -
Preparing to talk : Interaction between a linguistically enabled agent and a human teacher
