Grand Valley water management project

Presented during the USCID water management conference held on October 13-16, 2004 in Salt Lake City, Utah. The theme of the conference was "Water rights and related water supply issues."The Grand Valley Water Management Project (Project) consists of irrigation system improvements which provide the ability to reduce irrigation diversions from the Colorado River. The concept behind the Project was originally developed through a study conducted under the Bureau of Reclamation's General Investigations Program in cooperation with the Grand Valley Water Users Association and California Polytechnic State University. The Project was subsequently adopted by the Upper Colorado River Recovery Implementation Program as a key component in the overall strategy to provide flow augmentation to critical habitat reaches of the Colorado River. The Project concept was previously reported in a paper presented at the October 1998 USCID Conference. Project performance and cost effectiveness is exceeding expectations. When totally completed, the Project will conserve water at a unit cost of approximately $ 9 per acre-foot per year. This paper provides a brief background on the technical aspects of the Project but primarily focuses on actual performance and institutional agreements required to implement the Project. Potential future applications of this highly cost effective concept to address environmental and/or human water uses are also briefly discussed.Proceedings sponsored by the U.S. Department of the Interior, Central Utah Project Completion Act Office and the U.S. Committee on Irrigation and Drainage

Sumozhe suppressed, huntuo halted: An investigation into the nature and stakes of the cold-splashing Sogdian festal dramas performed in early eighth century Tang China

This article investigates two specific dramatic elements-the huntuo and the sumozhe-at the core of the controversial cold-splashing Sogdian plays (pohan huxi. The huntuo could be a felt hat, an oilcloth, a pelt headdress, or a theatrical striptease. With deep multicultural roots, the sumozhe (samaja) combined masquerade, ambulatory drama, dance, and music into a boisterous spectacle. In addition to examining the high cultural stakes underlying the public performance and imperial support (or prohibition) of these plays in early eighth century Tang China, this essay proposes a link between these hibernal festal dramas and Turkish Köse plays

Modified Two-strand Spinning Part I: Theory

A modified two-strand spinning system is described in this study. This system differs from other two-strand spinning systems in that it has a pair of intennittent notch roller placed above the convergence point. The notch roller cyclically alters the number of twist in the two strands above the convergence point and increases the level of strand-twist in the folded structure below the convergence point. This leads to increased trapping of surface fibres so that the hairiness of the resultant yam can be reduced and its abrasion resistance improved. A mathematical analysis of this modified two-strand spinning system is presented in this part of the series.</jats:p

Modified Two-strand Spinning Part II: Geometry

Part 1 has dealt with the theoretical aspects of the modified two-strand spinning system. The application of a notch roller is the key modification. This part estimates the optimum geometry for the notch roller.</jats:p
