  • Characterization of pit latrines to support the design and selection of emptying tools in peri-urban Mzuzu, Malawi

    The urban areas of many low-income countries must balance a rising demand for pit latrines for household sanitation provision against limitations in space, resulting in a need for pit latrine emptying services. This study was undertaken in the peri-urban neighborhood of Area 1B in the city of Mzuzu, Malawi, to examine the characteristics of household pit latrines for designing and selecting ...

  • Advanced Condition Assessments: The benefits of using Pipe Penetrating Radar

    Abstract: Pipe Penetrating Radar (PPR) is the underground in-pipe application of GPR, a non-destructive testing method that can detect defects and cavities within and outside mainline diameter (>18 in/450 mm) nonmetallic (reinforced concrete, vitrified clay, PVC, HDPE, etc.) underground pipes. The key advantage of PPR is the unique ability to map pipe wall thickness and deterioration including ...

  • Introduction to Ground Penetrating Radar (GPR)

    About GPR Ground Penetrating Radar (GPR) is a non-invasive method of material analysis based on transmitting an ultra wide band EM signal into the materials. A part of the EM wave is reflected when it reaches a boundary between two materials with different electrical properties. The reflected signal gets recorded at the source of the EM wave and is displayed for the operator and ...

  • GPR goes underground: Pipe Penetrating Radar

    Abstract: Pipe Penetrating Radar (PPR) is the underground in-pipe application of ground penetrating radar (GPR) either robotically or by manned entry to reveal wall thickness, delamination, voids, and other conditions that enable more precise determination of pipeline integrity and verifications for trenchless technology rehabilitation. PPR, when applied to pipe-bursting applications, can ...

  • Investigations on drop penetration and wetting characteristics of powder-liquid systems in relation to the mixing of acrylic bone cement

    This study investigated methyl methacrylate – polymethyl methacrylate powder bed interactions through droplet analyses, using model fluids and commercially available bone cement. The effects of storage temperature of liquid monomer and powder packing configuration on drop penetration time were investigated. Methyl methacrylate showed much more rapid imbibition than caprolactone due to decrease in ...
