Physical measures to inhibit planktonic cyanobacteriae

In a small lake, intermittent destratification was installed after several other physico-chemical and physical in-lake therapy measures (phosphorus immobilization, permanent destratification) had been tested without great success. If an aerobic sediment-water interface can be maintained, intermittent destratification removes cyanobacteria and prevents optimal development of other members of the photoautotrophic plankton. During growing seasons, increasing abundances of small-bodied herbivores (Bosmina) and Daphnia may have accounted for relatively low phytoplankton biomass as well. Intermittent destratification is a very fast-working in-lake measure and seems to be applicable even in relatively shallow lakes (< 15 m), in which permanent destratification seems to be risky

Review of methods for assessing the carcinogenic hazards from coal-using energy technologies

This report contains material relevant to the development of methodologies for evaluating the cancer risks associated with atmospheric pollutants from coal combustion and conversion processes. Information is presented on methods and sources (1) of regression analyses in this field, and (2) of physically significant simulation mechanisms, including potential functional modules of such mechanisms, particularly those modules dealing with energy facility emission characterizations, atmospheric dispersion, aerochemistry, population exposure patterns, and carcinogenic dose-response studies. In addition to listings of several key references and bibliographies in these areas, there is a discussion of some of the research in progress, the urgency of the situation, and some of the barriers to the development and dissemination of timely results

Motivational Interviewing Education for San Mateo County’s Adolescent Healthcare Providers: Focus on Healthy Diet and Physical Activity

Motivational interviewing has been endorsed by San Mateo County as an evidence-based effective form of behavior change counseling. Eighty percent of pediatric healthcare providers in San Mateo County have been trained in motivational interviewing, however 70% of the providers use it less than 50% of the time. The goal of this project was to reeducate the adolescent providers of San Mateo County in motivational interviewing with an emphasis on individualized training and feedback, directed toward healthy diet and exercise. Results of the quality improvement project showed an average 2.5-point increase in provider confidence on a zero to ten-point scale, and average increase in the use of motivational interviewing of 2 patients per day. Providers reported overall satisfaction with the project and demonstrated continued interest in further use of motivational interviewing. Recommendations for continued quality improvement include extension of the project for further support in motivational interviewing practice and increasing macrosystem involvement by training more providers throughout San Mateo County
