Confined space fatalities
… difficult to identify information pertaining to confined space fatalities such as contributory factors, mechanisms of injury and other data of an epidemiological nature.

Polymerization in Confined Space
Polymerization of acrylamide in confined space was studied. The system used for the polymerization was a colloid of water/SDS/dodecane/pentanol. The colloidal was stable through the polymerization process only at specific compositions. The system revealed a lamellar water structure which housed the …

Shear relaxations of confined liquids
Ultrathin ($$10$\sp4$ Pa), probably due to interactions with flaws in the monolayers. Dramatic signs of wall slip were observed at large strains even at low pressures.

Seismic resiliency using confined masonry :
… catastrophes, especially in developing nations. Confined masonry (CM) structures have proven to be a viable solution for seismic resiliency in the unique restraints and conditions of developing nations. CM provides benefits of increased shear capacity with smaller concrete frame members that …

Adsorption in Confined Aqueous Films
This thesis describes direct measurements of equilibrium adsorption of ions in thin (< 100 nm) aqueous films. Adsorption in thin films is important because it is through adsorption that the stability of colloidal suspensions is frequently tuned. The vast majority of measurements of adsorption to …

Velocity profile in confined elliptic fractures
… on a fluid transient inside a tapered-elliptical-confined fracture. In order to do so, the non-uniform velocity profile in an elliptic fracture with laminar flow of both Newtonian and non-Newtonian fluids was calculated. A transient flow computer program is presented using the method of …

Confined Flow of Attractive Colloidal Suspensions
… particulate fluids flowing through complex confined geometries are frequently used in technological applications. While the flow properties of hard-sphere suspensions in micro-scale geometries have been studied extensively, the effects of interparticle attractions and particle size …

Self-organisation of confined active matter
Active matter theory studies the collective behaviour of self-propelled organisms or objects. Although the field has made great progress in the past decade, little is known of the role played by confinement and surfaces. This thesis analyses the self-organisation of dense bacterial suspensions in …

Structure and Dynamics of Confined Molecules
Dielectric spectroscopy was employed within a SFA in order to investigate confinement effects on the dynamics of liquid crystal thin films. No shift upon confinement was observed for the molecular tumbling and flip motions in the nematic state. However, an interesting difference was observed as a …

Diffusiophoresis in complex and confined fluids
Moving fluids at the micro- and nano-scales requires a different approach compared to the traditional methods based on pressure gradients. The increase of surface/volume ratio as the length of the systems decreases the efficiency of the latter. The use of thermodynamic forces such as electric …

Ultrafast Ultra-confined Plasmon Phonon Interactions
The research contained within this thesis focuses on understanding and interrogating nanometrically confined ultrafast plasmon-phonon interactions. Nanometric plasmonic confinement is achieved by coupling the charge oscillations of a single gold nanoparticle to a gold substrate. This confines the …

Liquid crystal films confined between patterned substrates.
… this thesis, systems of nematic liquid crystals confined between patterned substrates have been studied using molecular computer simulation. The aim of this work, done in parallel with experimentalists in Leeds, has been to investigate the use of chemical patterning as a novel method for …

Simulation of Magnetically Confined Inductively Coupled Plasma
<p>In this work, a new parallel coil design was presented to address the need for high density inductively coupled plasmas with enhanced properties and a more uniform and consistent distribution, suitable for large-area material processing. Fluid model simulations of 3D argon inductively coupled …

Transverse and Longitudinal Tunneling in Confined Heterostructures
… tunneling effects and their application in confined heterostructures. In particular, three different three-terminal devices are studied which take advantage of the quantum-mechanical nature of electrons and holes to exhibit negative differential resistance (NDR) via tunneling.
