A method for calculating the effects of design errors and measurement errors on pump performance

Technique has been developed for calculating effects of design errors and measurement errors on pump performance. Error equations and charts are utilized to relate amount of error in given performance parameter to amount of error in given design or measured variable. Error equations were derived primarily for axial flow pumps, but are not limited to axial flow

Soft, thermally conductive material

Silicon rubber filled with high percentage of silver-plated copper microspheres provides soft, thermally conductive seat for thermal switch. Material also could be used in thin sheet form to prevent corrosion between dissimilar metals while maintaining good thermal communication. It could be used as thermal gasketing

Theory of Change As A Tool For Strategic Planning

The purpose of this paper is to introduce the use of the Theory of Change approach for planning community-based initiatives. Through lessons learned from a case study of how TOC was applied during the planning phase of The Wallace Foundation Parents and Communities for Kids (PACK) initiative, the utility of this technique and the challenges involved in employing it are illustrated. The case study was designed to highlight lessons that will be of most interest to program planners, evaluators, and funders who are interested in applying this method to their work

High performance ammonium nitrate propellant

A high performance propellant having greatly reduced hydrogen chloride emission is presented. It is comprised of: (1) a minor amount of hydrocarbon binder (10-15%), (2) at least 85% solids including ammonium nitrate as the primary oxidizer (about 40% to 70%), (3) a significant amount (5-25%) powdered metal fuel, such as aluminum, (4) a small amount (5-25%) of ammonium perchlorate as a supplementary oxidizer, and (5) optionally a small amount (0-20%) of a nitramine
