The development and evaluation of a 2-dimensional physical model, which is designed to assist in the characterisation of complex solute transport problems in porous media, is described. The laboratory model is a transparent 2-dimensional porous media of nominal thickness and uses a non-invasive imaging technique in conjunction with a fluorescent dye tracer(More)
A novel combination of noninvasive imaging with an oxygen sensitive fluorescent indicator was developed to investigate the biodegradation processes occurring at the fringe of a solute plume, where the supply of oxygen was limited. A thin transparent porous matrix (156 x 120 x 3 mm) was made from quartz plates and quartz sand (212-300 microm) and enriched(More)
Travel Medicine has emerged as a distinct entity over the last two decades in response to a very substantial increase in international travel and is now forging its own identity, remit and objectives for care of the traveller. Crucial to the formation of any speciality is the definition of recommendations for its practice. This is particularly important and(More)
This paper describes an investigation into non-equilibrium partitioning tracer transport and interaction with non-aqueous-phase liquid (NAPL) contaminated water-saturated porous media using a two-dimensional (2-D) physical modelling methodology. A fluorescent partitioning tracer is employed within a transparent porous model which when imaged by a CCD(More)
The yield-line method of analysis is a long established and extremely effective means of estimating the maximum load sustainable by a slab or plate. However, although numerous attempts to automate the process of directly identifying the critical pattern of yield-lines have been made over the past few decades, to date none has proved capable of reliably(More)
This article was written to describe a collaborative effort between the University of Mississippi Medical Center and the Delta Health Alliance to increase primary care providers in the 18 counties designated as the Mississippi Delta. Journals compiled by trainees were analyzed to reveal issues significant to practicing in a rural area from the perspective(More)
