Study of the lithology, petrology and rock chemistry for the Pyramid Mountains, New Mexico

Rock and soil samples were collected at 24 sites within the Pyramid Mountains of southwestern New Mexico. The site locations are specified as 10-acre plots within the Section, Township, and Range land survey system. Hand specimen are described. The specimen were analyzed by X-ray fluorescence. The technique is designed to obtain good analysis for silica. The other elements are run so that matrix factor logic can be used to adjust the silica intensities, and to compensate for the element interaction

Building a workforce from preschool up: a western Massachusetts commitment

With the western Massachusetts economy struggling in 2005, area leaders formed the Berkshire Compact to develop solutions. As the cornerstone of a comprehensive plan, members are pursuing efforts to interest children at younger ages in higher education.Education - Massachusetts ; Economic conditions - Massachusetts ; Labor market - Massachusetts

Supersymmetric quantum mechanics and the Korteweg-de Vries hierarchy

The connection between supersymmetric quantum mechanics and the Korteweg- de Vries (KdV) equation is discussed, with particular emphasis on the KdV conservation laws. It is shown that supersymmetric quantum mechanics aids in the derivation of the conservation laws, and gives some insight into the Miura transformation that converts the KdV equation into the modified KdV equation. The construction of the $\tau$-function by means of supersymmetric quantum mechanics is discussed.Comment: 16 pages, latex, EFI 93/2

Precision Tests of Electroweak Physics

We review the current status of precision electroweak measurements and the constraints they impose on new physics. We perform a model independent analysis using the STU-formalism of Ref. 1, and then discuss how the Z-pole data from LEP and SLD can be used to constrain models that are not covered within that framework.Comment: 1 cover page + 8 pages, 8 postscript figures, LaTeX2e, ws-p9-75x6-50.cls, Talk presented at Hadron 13, Mumbai, India, January 14-20, 199
