    Notes: Abstract Diazepam was compared to placebo and phenobarbital sodium in a double-blind study with 472 anxious psychoneurotic patients. Patients were treated in 3 settings — medical clinic, general practice, and private psychiatric practice. The treatment setting was found to be at least as important as the medication in producing a treatment response. Drug effects were pronounced. Compared to phenobarbital patients, diazepam patients more often completed the study, followed prescribed dosage, and reported fewer side reactions. Diazepam patients did not differ from placebo patients in dosage intake or side effects, only in higher completion rate. Population effects indicated clinic patients to drop out and deviate from dosage more than private patients. General practice patients reported the most and private psychiatric patients reported the least side effects. These differences are explained in terms of patient background and behavioral patterns and of a medical as opposed to a psychiatric orientation toward treatment.

    Notes: Abstract Under the Great Lakes Water Quality Agreement of 1978 between the United States and Canada, as amended in 1987, an ecosystem objective with associated indicators for Lake Superior was adopted, and a commitment was made to develop ecosystem objectives and indicators for each of the other Great Lakes. Building upon a history of activities within the International Joint Commission related to the development of ecosystem indicators for Lake Superior and for mesotrophic waters, a binational Ecosystem Objectives Work Group (EOWG) has been established by the U.S. and Canada and charged with developing ecosystem objectives for the Great Lakes, beginning with Lake Ontario. These objectives are primarily biological in nature, in contrast to chemical objectives. The approach of the EOWG is to identify in sequence: (1) broad ecosystem goals, (2) a suite of objectives whose attainment would ensure achievement of the goals, and (3) one or more measurable indicators of progress toward meeting each objective. Societal values are reflected in the goals and objectives following consultation with competing users of ecosystem resources. Identification of appropriate indicators requires the assistance of technical experts. The experience of the EOWG in developing ecosystem objectives for Lake Ontario illustrates the application of this process.

    Notes: Two series of glass-reinforced diallyl phthalate molding compounds from two different manufacturers were evaluated using a Rheometrics, Inc. Mechanical Spectrometer and a Brabender Torque Rheometer. Comparison of reactivity and minimum viscosity as measured by these two instruments is presented. The Mechanical Spectrometer appears capable of differentiating smaller changes in melt viscosity than does the Brabender Torque Rheometer.
