Understory response to tree harvesting in pinyon-juniper woodlands

Creator:: Everett, Richard L.
Abstract:: Understory species associations and their association with tree species were examined on three intensively studied stands. We studied the chronosequence of understory species associated with different aged singleleaf pinyon (Pinus monophylla Torr. and Frem.) trees. Mid- to late pinyon-juniper understory succession was found to be more spatial than floristic in...

Studies in molybdenum oxide catalysts : I. Metal vapor reactions of molybdenum trioxide with various alkoxy silanes : II. Investigation of oxide supported molybdenum catalysts prepared from molybdenum(VI)dioxodiethoxide

Creator:: Huffman, David Earl
Abstract:: The cocondensation reactions of molybdenum trioxide vapor with tetraalkoxysilanes, trimethylalkoxysilanes, and hexamethyldisiloxane at -196°C were investigated. The products from the metal vapor reactions of tetramethoxysilane, tetraethoxysilane, and tetrapropoxysilane were characterized as molybdenum(VI)dioxodialkoxy compounds. The isolated compounds were found to be polymeric in the solid state by bridging through alkoxide groups....
