Aspen Decline, Aspen Chemistry, and Elk Herbivory: Are They Linked? [PDF]
Rangelands, 2008 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 the Uinta National Forest aspen cover has been reduced by nearly 40%

Aspen Soils Retain More Dissolved Organic Carbon Than Conifer Soils in a Sorption Experiment
Frontiers in Forests and Global Change, 2020 The effect tree species have on soil organic carbon (SOC) has been hotly debated but, so far, few clear patterns have emerged. One example of a differing tree species effect on SOC are aspen forests in North America, which have been found to have more ...

Heat Pump Efficiencies Simulated with Aspen HYSYS and Aspen Plus [PDF]
Linköping Electronic Conference Proceedings, 2015 The efficiency of a heat pump system has been calculated for varying temperature conditions, refrigerants, simulation programs and thermodynamic models. Evaluated components are ammonia, the chlorofluorocarbons R-11, R-12, R-22 and propane. The equations of state Peng-Robinson (PR) and SoaveRedlich-Kwong (SRK) and the activity model NonRandom-Two ...

Controls of Initial Wood Decomposition on and in Forest Soils Using Standard Material
Frontiers in Forests and Global Change, 2022 Forest ecosystems sequester approximately half of the world’s organic carbon (C), most of it in the soil. The amount of soil C stored depends on the input and decomposition rate of soil organic matter (OM), which is controlled by the abundance and ...
