Investigation of nicotine binding to THP-1 cells : evidence for a non-cholinergic binding site
(2001)Nicotine is known to modulate immune function, but reports have produced conflicting evidence as to whether nicotinic acetylcholine (nACh) receptors are responsible for these effects. This study was designed to examine the ... -
Investigation of Optimal Cue to Instruction for Pelvic Floor Muscle Contraction in Women Using Ultrasound Imaging
(University of Hertfordshire, 2014-06-18)Background Pelvic floor muscle (PFM) training is recommended as first line conservative management for stress urinary incontinence (SUI). The fundamental issue of how to optimally contract the PFM has not previously been ... -
Investigation of optimal cues to instruction for pelvic floor muscle contraction : A pilot study using 2D ultrasound imaging in pre-menopausal, nulliparous, continent women
(2011)Aims: Optimal urethrovesical positioning (UVP) may be important for continence. Pelvic floor muscle contraction (PFMC) influences UVP. PFMC instruction cues vary and often encourage anterior PFM recruitment that may result ... -
Investigation of proton-induced reactions on Germanium isotopes
(2008-01)The cross sections of the (70)Ge(p,gamma)(71)As and (76)Ge(p, n)(76)As reactions have been measured in the energy range relevant for the astrophysical p-process (1.6-4.4 MeV). The proton beam was provided by the Van de ... -
Investigation of self-organising dynamic neural tree networks
(University of Hertfordshire, 1995)Self Organising Dynamic Neural Tree Networks (DNTNs) provide hierarchical clustering that is potentially applicable to large data sets. Two DNTN models have been produced by Racz and Klotz and Li et al. Four DNTN variants ... -
Investigation of skin permeation using ATR-FTIR spectroscopic imaging and multivariate target factor analysis
(2010-10)ATR-FTIR spectroscopic imaging permeation experiments of a model formulation across stratum corneum (SC) were conducted to acquire further understanding of the mechanism of drug permeation. Quantitative iterative target ... -
An investigation of stability of a control surface with structural nonlinearities in supersonic flow using Zubov's method
(2009-08-07)It is well known that the presence of nonlinearities may significantly affect the aeroelastic response of an aerospace vehicle structure. In this paper, the aeroelastic behaviour at high Mach numbers of an all-moving control ... -
Investigation of the association and flexibility of cationic lipidic peptide dendrons by NMR spectroscopy
(2005-01-01)The cationic peptide dendrons synthesized and studied are lower generation polylysine-based partial dendrimers with or without lipid chains in the core. The dendrons with lipidic chains can be utilized as protein and ... -
An Investigation of the Degree of Market Power in the Greek Manufacturing and Service Industries
(2017-12-31)This paper investigates the degree of market power in the Greek manufacturing and service industries over the period 1970–2007. The markup model developed by Hall (1988) and Roeger (1995) is taken into consideration where ... -
Investigation of the dependency of the drivers’ emotional experience on different road types and driving conditions
(2019-08-02)The growing sophistication of technologies and sociological advances are major causes for the dramatic change the automotive sector is currently undergoing. To address changes from a human-centered design perspective an ... -
Investigation of the diurnal pattern of the vertical distribution of pollen in the lower troposphere using LIDAR
(2013)The diurnal pattern of the vertical distribution of biogenic pollen in the lower troposphere was investigated by LIDAR. Meteorological data were taken at the ground. Pollen concentrations were measured at the surface using ... -
Investigation of the Effect of Substitutions on the Electronic and Optical Properties of the Sumanene Molecule
(2024-01-01)Sumanene (C21H12) is the smallest bowl-shaped molecule containing a central benzene ring, which is alternately surrounded by another 3 benzene rings and cyclopentadiene rings. In this study, the effect of various electron ... -
An investigation of the effectiveness of a voluntary sector psychodynamic counselling service
(2000)Clients attending a London voluntary sector counselling centre completed assessments pre- and post-psychodynamic counselling and at follow-up. Although there was a very high attrition rate following initial assessment, ... -
