BACKGROUND & OBJECTIVES Prevention of malaria is a major technical and operational problem in displaced and mobile populations such as refugee camps and temporary labour settlements. Insecticide incorporated plastic sheeting is a new technology to control mosquitoes in emergency shelters and also temporary habitations at different locations. In view of this, efficacy of ZeroFly® , an insecticid...

Timber panels and cold-formed steel sheeting are widely used in the construction industry, especially prefabricated structures, temporary housing informal settlements. This is because these materials available, can be cut fixed with hand tools, their lightweight makes them easy to transport build with. When together, there a potential for composite action developing between timber underlying sh...

This paper focuses on the adverse effects of soil sodicity and alkalinity growth barley (Hordeum vulgare L.) in a rainfed environment south-western Australia. These conditions cause accumulation salt (called ‘transient salinity’) root zone, which decreases solute potential solution, particularly at end growing season as dries. We hypothesized that two approaches could help overcome this stress:...

Image warping, often referred to as “rubber sheeting” represents the deformation of a domain image space into a range image space. In this paper, a technique is described which extends the definition of a rubber-sheet transformation to allow a polygonal region to be warped into one or more subsets of itself, where the subsets may be multiply connected. To do this, it constructs a set of “slits”...

Since silicone gels were first used in the treatment of hypertrophic scars (HS) and keloids (K) they have proved useful and safe. Depending on the specific investigation, the application of silicone gels showed improvements in redness, itching, texture and thickness of HS and K in 60% to 100% of cases. Generally, texture was the first scar characteristic to change, followed by color and height....

Head-mounted projective displays (HMPD's) are a novel type of head-mounted display. A HMPD consists of a miniature projection lens mounted upon the user's head and retroreflective sheeting material placed strategically in the environment. First, the imaging concept of a HMPD is reviewed and its potential advantages and disadvantages are discussed. The design and a bench prototype implementation...
