A public attitudes survey was conducted in neighborhoods adjacent to a radioactively contaminated site whose remediation is now under the auspices of the U.S. Department of Energy's Formerly Utilized Sites Remedial Action Program (FUSRAP). The survey's purpose was to ascertain levels of actual and desired public involvement in the remediation process; to identify health, environmental, economic...

OBJECTIVES This prospective study describes the impact of residential lead-based-paint hazard remediations on children with mildly elevated blood lead levels. METHODS Changes in blood lead levels were observed following paint hazard remediation alone and in combination with soil abatement. RESULTS After adjustment for the confounding variables paint hazard remediation alone was associated w...

This investigation was undertaken to determine the factors influencing electrokinetic remediation of soils from petroleum pollutants. The remediation method was applied in two versions: (i) static and (ii) flowing, when a sample was washed with leaching solution. It was found that all the soils studied can be purified using this technique. It was also observed that the mineral and grain-size co...

Acute and chronic pollution of environments with crude oil does not bode well for biota living within the vicinity of polluted environments. This is due to environmental and public health concerns on the negative impact of crude oil pollution on living organisms. Enhancing microbial activities by adding nutrients and other amendments had proved effective in pollutant removal during bioremediati...

Radon remediation in schools was identified early on as a potential priority for governments. The exposure reduction attributable to schools remediation can be substantial (1). Epidemiological and technical radon research has produced information which has enabled attention to be turned to specific effectiveness questions regarding radon identification and remediation programmes in buildings, i...

We present an empirical approach to adaptively selecting a tutoring system’s remediation strategy based on an annotated corpus of human-human tutorial dialogues. We are interested in the remediation selection problem, that of generating the best remediation strategy given a diagnosis for an incorrect answer and the current problem solving context. By comparing the use of individual remediation ...

in recent decades, attention to contamination propagation into soils and underground water has increased, which has led to a rise in the studies on soil contamination problems and methods of in-situ remediation. in this research, effective parameters on oil contamination propagation in soils and underground water have been investigated using fem in order to determine propagation patterns. the m...

Cognitive deficits in schizophrenia are pervasive, severe, and largely independent of the positive and negative symptoms of the illness. These deficits are increasingly considered to be core features of schizophrenia with evidence that the extent of cognitive impairment is the most salient predictor of daily functioning. Unfortunately, current schizophrenia treatment has been limited in address...

BACKGROUND With the increasing use of competency-based evaluations we now have more and better ways to identify performance deficiencies in our learners. Yet the emphasis placed on identifying deficiencies appears to exceed that given to improving these deficiencies. AIMS Here we describe the program at the University of Calgary for mentoring students with repeated performance deficiencies. W...

Electrokinetic remediation technology is one of the developing technologies that offers great promise for the cleanup of soils contaminated with heavy metals. However, the performance of an electrokinetic remediation system depends on the interaction of a complex set of interrelated system variables and parameters. Many of these interactions were addressed in this study by incorporating geochem...
