Breeding Birds In Uncut Aspen And 6- To 10-Year-Old Clearcuts In Southwestern Colorado, V.E. Scott, G.L. Crouch
Breeding Birds In Uncut Aspen And 6- To 10-Year-Old Clearcuts In Southwestern Colorado, V.E. Scott, G.L. Crouch
Aspen Bibliography
Numbers of breeding birds were estimated for various sizes and ages of clearcuts, for edge habitat created by the clearcuts, leave strips between clearcuts, and uncut aspen forest (controls). Total numbers of birds were not different among three size classes or five age classes of clearcuts. Total were lower on clearcuts than on edges but not different from controls or leave strips.
Progress In Bleaching Pulps With The Sulfite-Air System, E. L. Springer, J. D. Mcsweeny
Progress In Bleaching Pulps With The Sulfite-Air System, E. L. Springer, J. D. Mcsweeny
Aspen Bibliography
The effects of pulp pretreatment. pulp consistency. and quantity of sulfite added on final pulp brightness were studied using the cupric ion catalyzed sodium sulfite-air bleaching system. Aspen kraft pulp that had been partially delignified by chlorination and alkaline extraction was used. Highest brightnesses were attained by pretreating the pulp with cupric ion and by using the highest practical consistency. Brightness increased. but at a decreasing rate, with increases in added sulfite. A search was made for other catalysts. Nickelous ion vas found to be effective. but not quite as good as cupric ion. Spruce and aspen kraft pulps. partially …
