... This new technology was designed to form high-quality “formed-in-place” barrier walls in soil in a more continuous and uniform manner than the two-step, excavate and replace, processes of conventional slurry trenching. Soils in the path of the device are pulverized in-situ and liquified by high...

... Protective and conventional fabrics are being investigated with emphasis on comfort as well as aerosol and chemical protection efficacy. Broad assault protection is assessed by measuring aerosol barrier efficiency using aerosolized polystyrene latex spheres and by measuring chemical protection...
