Pull-off adhesion fb, in practice determined by the seminondestructive pull-off method, is a measure of the interlayer bond. It should be noted that the effectiveness of the pull-off method depends on the number of cores drilled. According to [1], one core per 3 m2 of floor should be drilled. Such a high density of cores drilled has a significant adverse effect on the condition of the tested fl...

Apulia, in the absence of surface water, is one of the Italian regions which satisfy their water requirements by drawing large quantities (over 40%) of its water from underground resources. The large amounts drawn from these resources in the last few years due to increasing human activity on the territory has determined a general and inevitable reduction of the quality of the underground water ...

The use of hazardous, arsenic-bearing groundwater for drinking, cooking, and irrigation has led in Bangladesh to what has been described by a leading epidemiologist as the worst mass poisoning of a human population in history (Smith et al. 2000). While surface waters usually have a very low dissolved arsenic content, the widespread occurrence of hazardous pathogens in rivers and ponds prompted ...

Accidental contamination of livestock feed in 1973 by polybrominated biphenyls (PBB) led to the destruction of over 30,000 animals in Michigan. Animal carcasses of mostly dairy cattle along with some beef cattle, hogs, sheep and rabbits destroyed under the Federal Food and Drug Administration guidelines were disposed on the land at an environmentally safe site in Kalkaska County, Michigan. The ...

Barind Tract of Bangladesh is one of the driest parts of the region where surface water supplies are limited. Large parts of this tract used to be fallow land because there were no major irrigation facilities until mid 1980s. A detailed hydro geological and groundwater survey of Bangladesh was implemented by UNDP in February 1978; Barind was described as follows, “the zone lie on the western Ra...

PURPOSE To determine the prevalence of trachoma and to measure the impact of the SAFE strategy (World Health Organization GET 2020 strategy) for treating trachoma in the Gwembe District of Southern Zambia. DESIGN This is an observational study of the introduction of the SAFE strategy employing a collaborative approach and its impact on trachoma in the area. PARTICIPANTS Three thousand eight...

BACKGROUND The first objective of this study was to investigate the public perceptions of private water and alternative sources with respect to safety, quality, testing and treatment in Newfoundland and Labrador (NL), Canada. The second objective was to provide public health practitioners with recommendations for improving knowledge translation (KT) efforts in NL, based on assessments of respon...

A program of field loading tests was conducted to measure the axial response of drilled foundations constructed using a variety of different drilling techniques. The research was performed at the Auburn University National Geotechnical Experimentation Site at Spring Villa, Alabama in Piedmont geology composed of silty soils formed by weathering of parent metamorphic rocks. A total of 10 drilled...
