Using the situated expectancy value theory (SEVT), we explored self-perceived attainment perspectives of adults with low literacy on skill-based (i.e., reading, writing, listening, speaking) and life-based management day-to-day challenges, use skills in daily living, confidence) improvements following a literacy-focused remediation program. Participants (N = 103; Canadian, urban adults) complet...

Groundwater contamination is the result of multiple human activities, such as agriculture, industrial practices and military operations. The traditional remediation approach is to combine pump-and-treat for plume containment and contaminant capture, with other remediation technology for source control. Pump-and-treat systems are expensive, typically requiring high installation and operation cos...

Surfactant-enhanced aquifer remediation (SEAR) is widely considered a promising technique to remediate dense nonaqueous phase liquid (DNAPL) contaminations in-situ. The costs of a SEAR remediation are important and depend mostly on the setup of the remediation. Costs can be associated with the installation of injection and extraction wells, the required time of the remediation (and thus labor c...

We describe the use of catalytically self-propelled microjets (dubbed micromotors) for degrading organic pollutants in water via the Fenton oxidation process. The tubular micromotors are composed of rolled-up functional nanomembranes consisting of Fe/Pt bilayers. The micromotors contain double functionality within their architecture, i.e., the inner Pt for the self-propulsion and the outer Fe f...

The 2003 flood of the Muda River reached 1,340 m3 /s at Ladang Victoria and adversely impacted 45,000 people in Malaysia. A flood control remediation plan proposed a levee height based on a 50-year discharge of 1 ,815 m3 /s obtained from hydrologic models. This design discharge falls outside the 95% confidence intervals of the flood frequency analysis based on field measurements. Instream sand ...

Glossary brownfield A piece of previously used land that requires some remediation of contaminants, pollutants, debris or hazardous substances in order for it to be reused and redeveloped. containerization A shipping method which uses standardized containers to store and transport goods and materials. gentrification A complex process whereby a group of middle class people move into a previously...

Nitrates pollution of waters is a worldwide problem and its remediation is a big challenge from the technical and the scientific point of view. One of the most used and promising cleaning techniques is the biological treatment of wastewaters operated by denitrifying bacteria. In this paper we begin a thorough study of denitrifying performances of the bacterium Azospira sp. OGA 24, recently isol...

OBJECTIVE Our pilot study aims to investigate the efficacy of a Short-Term (4 weeks) Psychiatric Rehabilitation Program (S-T PsyRP), without specific cognitive remediation trainings, on the neuropsychological performance and psychosocial functioning of inpatients with Major Depressive Disorder (MDD) or Bipolar Disorder (BD). Published studies with similar aims are lacking. METHODS Fifty-three...

EPA Region 5 expects to post in August 2014 a full and open solicitation for environmental dredging in Great Lakes' rivers and harbors and handling of dredged sediments, NAICS code 562910. EPA anticipates 5-year, multiple-award, indefinite-delivery, indefinite-quantity type contracts with firm-fixed-price task orders, at an estimated value of $300 million per contract. GLNPO executes a budget o...
