ERIC ED223456: A Collection of Ideas and Materials for Vocational Trainers. Water Quality Instructional Resources Information System. Monograph Series: Improving Instruction.

www.archive.org/details/ERIC_ED223456...
A great variety and amount of teaching materials and methods related to water quality and other Environmental Protection Agency (EPA) concerns have been developed. Program developers/trainers responsible for instructional programs will find in ERIC and the Instructional Resources Information System (IRIS) enough material to organize dozens of short courses and/or hundreds of instructional hours. The problem is not lack of material but rather selecting and/or developing material that is most useful in a specific situation, achieves certain objectives, honors the needs and concerns of adult learners, and permits instructors to use materials/methods which capitalize on their teaching strengths. Cited in this document are ideas, materials, and methods that may be useful to persons involved in designing instructional programs for water quality or other EPA concerns. The first section provides characteristics of adult learners with related teaching implications. The second section focuses on teachers of adults. The third section (the major part of the document) focuses on various aspects of instructional planning and teaching, including sample lessons found in the ERIC and IRIS literature. Reference materials (with abstract and availability) are provided in the fifth section. EPA Instructional Resources Center (IRC) activities are described in the final section. (Author/JN)

Comparing the Selection and Placement of Best Management Practices in Improving Water Quality Using a Multiobjective Optimization and Targeting Method.

www.archive.org/details/pubmed-PMC3987017...
This article is from International Journal of Environmental Research and Public Health , volume 11 . Abstract Suites of Best Management Practices (BMPs) are usually selected to be economically and environmentally efficient in reducing nonpoint source (NPS) pollutants from agricultural areas in a watershed. The objective of this research was to compare the selection and placement of BMPs in a pasture-dominated watershed using multiobjective optimization and targeting methods. Two objective functions were used in the optimization process, which minimize pollutant losses and the BMP placement areas. The optimization tool was an integration of a multi-objective genetic algorithm (GA) and a watershed model (Soil and Water Assessment Tool—SWAT). For the targeting method, an optimum BMP option was implemented in critical areas in the watershed that contribute the greatest pollutant losses. A total of 171 BMP combinations, which consist of grazing management, vegetated filter strips (VFS), and poultry litter applications were considered. The results showed that the optimization is less effective when vegetated filter strips (VFS) are not considered, and it requires much longer computation times than the targeting method to search for optimum BMPs. Although the targeting method is effective in selecting and placing an optimum BMP, larger areas are needed for BMP implementation to achieve the same pollutant reductions as the optimization method.

DTIC ADA378533: Hydrodynamic and Water Quality Model Study of San Juan Bay Estuary

www.archive.org/details/DTIC_ADA378533...
This report describes a three-dimensional hydrodynamic and water quality model study of the San Juan Bay and Estuaries system conducted to evaluate the effectiveness of various management alternatives for improving water quality. Alternatives included methods to increase flushing, reduce pollutant loadings, and combinations of the two. The CH3D-WES hydrodynamic model and the CE-QUAL-ICM water quality model were employed in the study. The models were indirectly coupled and were adjusted and calibrated against data collected during the summer of 1995. Analysis of various management scenarios revealed that a combination of widening and deepening of Cano Martin Pen a, filling of dredged submerged borrow pits, and removal of un-sewered loads in Cano Martin Pena provided the greatest water quality benefits.

Effects of drinking hydrogen-rich water on the quality of life of patients treated with radiotherapy for liver tumors.

www.archive.org/details/pubmed-PMC3231938...
This article is from Medical Gas Research , volume 1 . Abstract Background: Cancer patients receiving radiotherapy often experience fatigue and impaired quality of life (QOL). Many side effects of radiotherapy are believed to be associated with increased oxidative stress and inflammation due to the generation of reactive oxygen species during radiotherapy. Hydrogen can be administered as a therapeutic medical gas, has antioxidant properties, and reduces inflammation in tissues. This study examined whether hydrogen treatment, in the form of hydrogen-supplemented water, improved QOL in patients receiving radiotherapy. Methods: A randomized, placebo-controlled study was performed to evaluate the effects of drinking hydrogen-rich water on 49 patients receiving radiotherapy for malignant liver tumors. Hydrogen-rich water was produced by placing a metallic magnesium stick into drinking water (final hydrogen concentration; 0.55~0.65 mM). The Korean version of the European Organization for Research and Treatment of Cancer's QLQ-C30 instrument was used to evaluate global health status and QOL. The concentration of derivatives of reactive oxidative metabolites and biological antioxidant power in the peripheral blood were assessed. Results: The consumption of hydrogen-rich water for 6 weeks reduced reactive oxygen metabolites in the blood and maintained blood oxidation potential. QOL scores during radiotherapy were significantly improved in patients treated with hydrogen-rich water compared to patients receiving placebo water. There was no difference in tumor response to radiotherapy between the two groups. Conclusions: Daily consumption of hydrogen-rich water is a potentially novel, therapeutic strategy for improving QOL after radiation exposure. Consumption of hydrogen-rich water reduces the biological reaction to radiation-induced oxidative stress without compromising anti-tumor effects.

DTIC ADA425078: The Development and Use of Distribution System Models for Improving the Security of Drinking Water System

www.archive.org/details/DTIC_ADA425078...
Guidance was developed for water system distribution software application to security related uses. This guidance was broken into four uses: model development, pre-scenario analysis, post-scenario analysis, and detector placement analysis. This guidance allows a water utility to take a water modeling program, develop it, and then analyze how water systems will respond to different water security scenarios. This will help the utility determinate areas of vulnerability. This guidance will also allow the utility to evaluate the siting of detectors. Additionally, it will also allow analysis of post-scenario responses to determine the travel of any contaminant that may have been introduced into the system. The detectability of Cryptosporidium parvum was then analyzed using normally water quality parameters, including turbidity, total organic carbon, pH, chlorine residual, and conductivity. The detection levels for this contaminant was then calculated, which was based on a statistically significant change in these parameters. This statistically significant change was the 3-sigma value. C,yptosporidium parvum was analyzed in the model using the modeling guidance with four different scenarios that were developed to determine the influence of feed methodology and location. The assumptions of the amount of Cryptosporidium parvum that could potentially be available were determined from the literature review. The results of the modeling showed that the Cryptosporidium parvum would be capable of producing widespread system contamination. This type of contamination would not likely produce a large number of fatalities, but there would be widespread illnesses caused throughout the system. It was found that contamination efficacy is dependent more on location of the backflow rather than the pumping method. The detection methods evaluated would detect the contaminant, but at concentrations much greater than the infective dose.
