Changes in PT and OT Students’ Self-Efficacy Using an Interprofessional Case Based Experience
This poster describes an interprofessional simulation activity for physical therapy and occupational therapy students and a research study exploring the impact of the learning experience
Advanced life support equipment for nitrogen tetroxide environments
Design constraints considered in an effort to improve the self-contained atmospheric protection ensemble (SCAPE) are discussed. Emphasis is placed on overcoming the hazards of personnel engaged in orbiter crash/rescue operations. Specific topics covered include: suit material permeability; sealing of all suit penetration; and maintaining a positive pressure within the suit

Supporting ODP - Translating LOTOS to Z
This paper describes a translation of full LOTOS into Z. A common semantic model is defined and the translation is proved correct with respect to the semantics. The motivation for such a translation is the use of multiple viewpoints for specifying complex systems defined by the reference model of the Open Distributed Processing (ODP) standardization initiative. The postscript version available here is an extended version of what was published

Sportfishing creel census pilot study
The sportfishing creel census project was originated to obtain information relating to the use of the Corpus Christi Bay area for sportfishing, the amount of fish caught and other environmental information relating to the total productivity cycles of the bay system. The Census is to be conducted during the summer months of June, July and August 1974 and the pilot study was made during August 1973. The total catch will be used in a current project to assess carbon, nitrogen, phosporous input and output to the bay system.March 15, 1974To The Lower Nueces River Water Supply DistrictMarine Scienc

Viewpoint consistency in Z and LOTOS: A case study
Specification by viewpoints is advocated as a suitable method of specifying complex systems. Each viewpoint describes the envisaged system from a particular perspective, using concepts and specification languages best suited for that perspective. Inherent in any viewpoint approach is the need to check or manage the consistency of viewpoints and to show that the different viewpoints do not impose contradictory requirements. In previous work we have described a range of techniques for consistency checking, refinement, and translation between viewpoint specifications, in particular for the languages LOTOS and Z. These two languages are advocated in a particular viewpoint model, viz. that of the Open Distributed Processing (ODP) reference model. In this paper we present a case study which demonstrates how all these techniques can be combined in order to show consistency between a viewpoint specified in LOTOS and one specified in Z.

Handbook on Hypergolic Propellant Discharges and Disposal
The efficiency of all treatment methods formerly or currently used in treating chemical wastes is assessed with emphasis on the disposal of hypergolic propellants. Maximum focus is on the space shuttle propellants MMH and N2O4. Except for hydrogen peroxide oxidizers, all the propellants are nitrogen based and can be potentially reduced to valuable plant nutrients. In theory, all the propellants can be reduced to carbon, hydrogen, nitrogen, and oxygen, except of fuming nitric acid which contains a small amount of fluorine. Appendices cover: (1) a general design criteria for disposal ponds; (2) thermal aspects of reaction in dilute solution; (3) gas bubble growth, detachment, and rise (4) absorption scrubber fundamentals and descriptions; (5) separation of a propellant vapor from a helium stream by permeation; and (6) atmospheric emission limits
