—Widespread establishment of seedling aspen (Populus tremuloides) occurred in Yellowstone National Park (YNP) following the extensive1988 fires. Aspen stands occupy ;2% of YNP and aspen stems are intensively browsed by native ungulates. Chemical composition, especially secondary compounds, may influence levels of herbivory and, hence, survival of aspen, but concentrations of such compounds in a...

Methanol (also known as CH3OH, methyl alcohol, hydroxymethane, wood or carbinol) is a widely used primary raw material. It one of the first organic chemicals to find extensive laboratory and industrial use. water are ideal binary systems that can be separated by conventional distillation. This study aims separate methanol-water using simulated double-effect distillation process in Aspen Plus. T...

As human activity continues to increase CO2 and O3, broad expanses of north temperate forests will be simultaneously exposed to elevated concentrations of these trace gases. Although both CO2 and O3 are potent modifiers of plant growth, we do not understand the extent to which they alter competition for limiting soil nutrients, like nitrogen (N). We quantified the acquisition of soil N in two 8...

In Rocky Mountain National Park (RMNP), aspen (Populus tremuloides Michx.) has been observed to be declining on elk (Cervus elaphus nelsoni) winter range for many decades. To support elk management decisions, the SAVANNA ecosystem model was adapted to explore interactions between elk herbivory and aspen dynamics. The simulated probability of successful vegetative regeneration for senescent aspe...

• A pre-combustion process based on [P 2228 ][CNPyr] was modelled and optimized. 80 operating configurations were techno-economic evaluated. Suitable pressures temperatures allowed minimizing capital operational costs. Direct costs lower than U.S. Department of Energy’s 40$/t CO2 goal achieved. H 2 production processes from steam methane reforming combined cycle power plants require carbon diox...

Development and change in forest communities are strongly influenced by plant-soil interactions. The primary objective of this paper was to identify how forest soil characteristics vary along gradients of forest community composition in aspen-conifer forests to better understand the relationship between forest vegetation characteristics and soil processes. The study was conducted on the Fishlak...
