Investigating the Properties of Brown Dwarfs Using Intermediate-Resolution Spectroscopy
(University of Hertfordshire, 2015-01-05)This thesis is an investigation into some properties of brown dwarfs using medium-resolution spectroscopy. In the first part of the thesis, I address the issue of parameter degeneracy in brown dwarfs. In the course of my ... -
Investigating the relationship between stress and worker behaviour
(1998)Direct care staff working in six residential group homes for people with intellectual disability were asked to complete a questionnaire which asked for information on levels of stress (anxiety and depression), the types ... -
Investigating the Role of Maintenance TMS Protocols for Major Depression: Systematic Review and Future Perspectives for Personalized Interventions
(2023-04-21)Repetitive Transcranial Magnetic Stimulation (rTMS) has been approved by the FDA as an effective intervention for Treatment-Resistant Depression (TRD). However, there is little evidence about maintenance protocol necessity. ... -
Investigating the Role of the Planar Cell Polarity (PCP) Protein CELSR1 in Breast Cancer
(2023-11-18)Planar cell polarity (PCP) is essential for generating highly organized tissue structures and for directional cell movement/migration. The role of PCP in embryogenesis is well-documented, however its role in adult pathologies, ... -
Investigating the spectra and physical nature of galaxy scale jets
(2021-10-13)Previous studies have shown that physically small, low-luminosity radio galaxies, which we refer to as galaxy scale jets (GSJ), could potentially have a significant effect upon the host galaxy's evolution. Using 6 arcsec ... -
Investigating the spectral age problem with powerful radio galaxies
(2020-02-01)The 'spectral age problem' is our systematic inability to reconcile the maximum cooling time of radiating electrons in the lobes of a radio galaxy with its age as modelled by the dynamical evolution of the lobes. While ... -
Investigating the suitability of high content image analysis as a tool to assess the reversibility of foamy alveolar macrophage phenotypes in vitro.
(2020-03-13)Many potential inhaled medicines fail during development due to the induction of a highly vacuolated or “foamy” alveolar macrophage phenotype response in pre-clinical studies. There is limited understanding if this response ... -
Investigating the surface inhomogeneities of the contact binary SW Lacertae : I. Doppler imaging
(2011)Aims : We aim to reconstruct the first detailed surface maps of the W UMa-type contact binary system, SW Lac. These maps should reveal the distributions of dark, magnetically active spot regions on the component stars and ... -
Investigating the transport of angular momentum from young stellar objects : do H2 jets from Class I YSOs rotate
(2008)In this pilot study, we examine molecular jets from the embedded Class I sources, HH26 and HH72, to search, for the first time, for kinematic signatures of jet rotation from young embedded sources -
Investigating the Unification of LOFAR-detected powerful AGN in the Boötes Field
(2017-08-01)Low radio frequency surveys are important for testing unified models of radio-loud quasars and radio galaxies. Intrinsically similar sources that are randomly oriented on the sky will have different projected linear sizes. ... -
Investigating the use of secondary organic aerosol as seed particles in simulation chamber experiments
(2011)The use of beta-caryophyllene secondary organic aerosol particles as seeds for smog chamber simulations has been investigated. A series of experiments were carried out in the Manchester photochemical chamber as part of the ... -
Investigating the use of the Motivation-Opportunity-Ability (MOA) Model to reveal the factors which facilitate or inhibit inclusive engagement within local community festivals
(2012-06-13)This paper aims to contribute to the debate on community engagement and participation in local community festivals and events by analysing the factors which either inhibit or facilitate engagement within local community ... -
Investigating university students' prior experiences of technology and their expectations of using technology in their studies
(Association for Learning Technology, 2007)Who are the university students of the 21st Century and what characteristics do they have in terms of their interest in using technology for learning? They have been called, for instance, 'the iPOD generation' from the ... -
An investigation and evaluation of variable-valve-timing and variable-valve-actuation strategies in a diesel homogeneous charge compression ignition engine using three-dimensional computational fluid dynamics
(2008-06-01)A three-dimensional computational fluid dynamics modelling was carried out to investigate effects of variable valve timing (VVT) and variable valve actuation (WA) on gas exchange and fuel-air mixing processes in a diesel ... -
Investigation by surface enhanced Raman spectroscopy of the effect of oxygen or hydrogen plasmas on the surface chemistry of adsorbate-covered gold island films
(1999)The effects of radio-frequency-excited oxygen and hydrogen plasmas on gold island films with adsorbed CN-, thiophenate, or p-nitrobenzoate ions have been investigated by surface-enhanced Raman spectroscopy (SERS). An oxygen ... -
An investigation into alleged 'hauntings'
(2003-05)In cases of alleged hauntings, a large number of seemingly trustworthy witnesses consistently report experiencing unusual phenomena (e.g. apparitions, sudden changes in temperature, a strong sense of presence) in certain ...
