Problem solving team interventions: Web-based and consultant-based experimental evaluations.

This research was designed to develop, implement, and evaluate an assessment and intervention protocol to increase problem-solving teams' (PSTs) adoption and implementation of evidence-based practices aimed at students with disruptive behavior problems. Participants included 15 PSTs. Adopting single-case design methodology, we examined whether a customized set of assessment and intervention consultant-led intervention procedures could be used to improve the activities, process, and recommendations of PSTs compared to a web-based intervention.

The effects of different storage conditions on polyether and polyvinylsiloxane impressions.

While being shipped to a laboratory, impressions can be exposed to excessive temperatures. This study compared the effects of different time and temperature storage conditions, including temperature extremes of 66 C and -10 C, on the accuracy of addition silicone and polyether impressions. The greatest distortion generally occurred as a result of the 66 C temperature extreme.

Metal binding by pharmaceuticals. Part 5. Interaction of Cd(II), Ni(II) and Pb(II) with the intracellular hydrolysis products of the anti-tumour agent ICRF 159 and its inactive homologue ICRF 192.

Formation constants for the cadmium(II), nickel(II) and lead(II) complexes of DL-NN'-dicarboxamidomethyl-NN'-dicarboxymethyl-1,2-diaminopr opane (ICRF 198) and the 1,2-diaminobutane homologue (ICRF 226) have been measured potentiometrically at 37 degrees C and I = 150 mmol dm-3 [NaCl]. In all titrations a competing ligand, known to complex strongly with the metal ion, and having its formation constants predetermined, was employed. The constants are used in computer simulation models to assess the relative efficacy of the agents in mobilizing these metals from plasma proteins into low-molecular-weight complexes and the results are compared to those for known chelating agents.
