Elevated concentrations of atmospheric carbon dioxide ([CO2]) and tropospheric ozone ([O3]) have the potential to affect tree physiology and structure and hence forest water use, which has implications for climate feedbacks. We investigated how a 40% increase above ambient values in [CO2] and [O3], alone and in combination, affect tree water use of pure aspen and mixed aspen-birch forests in th...

Although the effect of litter mixture on decomposition has been well documented, few studies have examined the relationships between richness and relative abundance of leaf species in litter mixture and changes in universal fungal communities during the decomposition process in temperate forests. In this study, we used the litterbag method and included three leaf litter species, i.e., aspen (Po...

T he first Aspen Lung Conference entitled “Symposium on Emphysema and the Chronic Bronchitis Syndrome,” was held in 1958. It’s purpose was to develop an understanding of what these terms meant and to begin to unravel the causes and factors associated with the prognosis. The original Aspen Emphysema Conferences were funded by contracts from a branch of the United States Public Health Service. Th...

Dynamic Reconfiguration is the process of changing a component-based system with minimum disruption and maximum automation. This process consists of three phases i.e. sensing the present state, planning for a new state and acting on the system to move it to the new state. Although, there are techniques and models for the sensing and acting phases, planning is a relatively neglected phase in thi...

“Lipid Accumulation in Hepatic and Extrahepatic Tissues,’’ a research seminar sponsored by the Aspen Bile Acid/Cholesterol Conference, Inc., was held at the Given Institute of the University of Colorado School of Medicine in Aspen, Colorado on August 17-20, 1991. This symposium was planned to bring together investigators who approach the general problem of tissue accumulation of lipids from dif...

A number of successful applications of automated planning and scheduling applications to spacecraft operations have recently been reported in the literature. However, these applications have been one-of-a-kind applications that required a substantial amount of development effort. In this paper, we describe ASPEN (Automated Planning/Scheduling Environment), a modular, reconfigurable application ...
