Steady State Simulation of a Rotary Kiln for Charcoal Activation
−− This work presents a mathematical modeling and steady state simulation study of the pilot scale rotary kiln behavior, which was designed to activate charcoal obtained from the raw materials of region of Cuyo-Argentina. The proposed model aims for acquiring useful information to select operating conditions and design parameters. It is a simplified mathematical model that consists of a system ...
متن کاملCharcoal Rot of Sorghum
Charcoal rot of sorghum causedby the fungus ~acrophorfdna phaseolina is a root andstalk rot disease of great destructive potential in most sorghum-growing regions. Improved, highyielding cultivars under good management tend to be very susceptible to the disease. M. phaseolina is a common soilborne, nonaggressive, and plurivorous pathogen that attacks plants whose vigor has been reduced by unfav...
متن کاملAspen Decline , Aspen Chemistry , and Elk Herbivory : Are They Linked ?
A spen (Populus tremuloides) provides important habitat for mammals and birds 1–3 , improves water retention in watersheds, 4 and has high aesthetic appeal in autumn. However, the amount and quality of aspen cover in the West has been declining for many years. For example, aspen cover in the Dixie and Fishlake National forests in Utah has decreased by more than 60% from historic levels, and in ...
متن کاملThermal Softening of Transgenic Aspen
Studies on the softening behavior of in situ lignin of normal wood in a given species have never been performed before due to the relatively narrow lignin content and lignin structural variation within one species. Using transgenic trees with different levels of lignin content and/or syringyl to guaiacyl propane (S/G) ratio helped us to overcome this problem. Submersion three-point bending and ...
متن کاملIndependent activation of cold acclimation by low temperature and short photoperiod in hybrid aspen.
Temperate zone woody plants cold acclimate in response to both short daylength (SD) and low temperature (LT). We were able to show that these two environmental cues induce cold acclimation independently by comparing the wild type (WT) and the transgenic hybrid aspen (Populus tremula x Populus tremuloides Michx.) line 22 overexpressing the oat (Avena sativa) PHYTOCHROME A gene. Line 22 was not a...
