Abstract In the framework of non-destructive-testing advanced seismic imaging techniques have been applied to ultrasonic echo data in order examine integrity an engineered test-barrier designed be used for sealing underground nuclear waste disposal site. Synthetic as well real multi-receiver acquired at test site were processed and imaged using Kirchhoff prestack depth migration reverse time (R...

BACKGROUND Home healthcare is one of the fastest growing sectors in the United States. Percutaneous injuries from sharp medical devices (sharps) are a source of bloodborne pathogen infections among home healthcare workers and community members. Sharps use and disposal practices in the home are highly variable and there is no comprehensive analysis of the system of sharps procurement, use and di...

This study presented the overview on behavior of bentonite-sand mixture used in high level radioactive waste disposal. Both unconfined compression test and triaxial were conducted out that unsaturated-saturated samples applied temperature effect below 100 degrees Celsius. Unconfined compressive strength was determined with various temperatures different relative humidity for unsaturated specime...

In recent times, the indiscriminate disposal of post-consumer plastic packaging material has received global attention. There is a need to develop an alternative from bio-based polymers reduce waste pollution. This work studied effects loading seaweed nanoparticles into agar matrix by analyzing physical, mechanical, water vapor barrier, and biodegradation properties, as well surface morphologic...

plastics, one of the most abundant materials in the world today, are one of the main sources of pollution. people’s perception of using and disposing plastic bags is primordial as they tend to be a major part of household solid waste. this study aims to determine community’s perception of usage and disposal of plastic bags in eastern ethiopia. a quantitative cross-sectional study has been condu...
