Absolute low-pressure calibration system

McLeod gage is used as the primary reference standard in a system used for absolute calibration of vacuum gages in the very low pressure range. The system involves steady-state flow of a gas through a cascade of differentially pumped chambers or stages connected by precisely defined orifices

The Use of Play Therapy with Adult Survivors of Childhood Abuse

Problem. A growing trend among therapists is the use of play therapy interventions with adult clients to facilitate resolution of early childhood trauma and to promote emotional and spiritual growth. The purpose of this study was to explore the use and effectiveness of play therapy techniques with adult survivors of childhood abuse. Method. In an exploratory approach, therapists were invited to participate in an online survey. Of the participating therapists, 21 agreed to a subsequent in-depth interview. The Theme Analysis for Word-Rich Data was used to identify themes from the interviews. Results. Play therapy with adult survivors of childhood abuse was used by 64.9% of the participating therapists in this study. Common techniques used in treating adult survivors were: (a) journaling, (b) sand tray, (c) art, (d) anger management, (e) imagery, (f) role play, and (g) humor. A categorization according to intent or goal of therapy was noted. When the intent was to express feelings, the art and sandplay techniques predominated. When the purpose was to manage anger, more physical activities were suggested. Therapists were asked to rate the effectiveness of play therapy with adult survivors. On a 5-point Likert scale, with 5 - Very effective and 1 = Ineffective, 81% of the participants selected either a 4 or 5, with the mode and median both being 5 = Very effective. In a process called Theme Analysis for Word-Rich Data, six themes emerged from analysis of the qualitative interviews. These were: (a) non-threatening, therapeutic environment, (b) therapist characteristics, (c) successful techniques, (d) developmental perspective, (e) justification for using play therapy, and (f) spirituality. These six themes became the building blocks for the proposed therapy model presented in this study. Conclusions. Results from this study suggest that play therapy is an effective approach in treating adult survivors. Further exploration is needed to formalize this approach and to empirically test its effectiveness. A conceptual model for practice is presented within this study to include (a) suggestions for therapist academic and practicum preparation; (b) suggested techniques; and (c) guidelines for theory development

Design, fabrication, assembly and delivery of a laboratory prototype of a residual gas analyzer

The design, development, and testing of a wide mass range residual gas analyzer which will be one component of an integrated real time contamination monitor system are described. The instrument has been developed and tested to the laboratory prototype phase, demonstrating the performance that can be expected from a flight instrument of similar design. The instrument's analyzer is of the quadrupole type and a cold cathode ion source is employed as the ionizer. The associated electronics supply all necessary operating and mass sweep voltages for the ionizer, analyzer and electron multiplier ion detector. The instrument features a very fast linear electrometer with automatic range changing. The full mass range of 2 to 300 amu is automatically and repetitively scanned every sixty seconds and suitable telemetry outputs are provided for intensity and mass identification as well as a digital identification of the electrometer range

Improved magnetron cold-cathode ion source

Cold cathode ionization source generates smaller amounts of spurious gases and has a higher sensitivity than commonly used hot-filament ion sources. Photon and X-ray background noise are reduced below detectable levels

Report to the Wisconsin Legislature on the Learnfare Evaluation (1991)

In July, 1987 the State of Wisconsin enacted legislation implementing a Learnfare policy for families with teenagers receiving Aid to Families with Dependent Children (AFDC) and who have not completed high school or obtained a GED. Under the policy families are denied AFDC support for teens (or teen parents) not attending school regularly. The Employment and Training Institute was selected by the state Department of Health and Social Services to conduct an evaluation of the program. This report was made to the state Legislature on the progress of the evaluatio
