Thin film composite (TFC) membranes of the prototypical polymer intrinsic microporosity (PIM-1) have been prepared by dip-coating on a highly porous electrospun polyvinylidene fluoride (PVDF) nanofibrous support. Prior to coating, support was impregnated in non-solvent avoid penetration PIM-1 inside PVDF network. Different non-solvents were considered and results compared with those dry When ap...

There is concern over the decline of aspen and the lack of successful regeneration due to excessive browsing of aspen suckers by cattle and other wild and domestic ungulates. We conducted a 2-yr study on Lassen National Forest, California, to aid development of cattle grazing strategies to enhance aspen regeneration. We evaluated seasonal biomass, nutritional quality, and utilization by cattle ...

Quaking aspen (Populus tremuloides) is commonly believed to be declining throughout western North America. Using a historical vegetation map and Landsat TM5 imagery, this study detects changes in regional aspen cover over two different time periods of 85 and 18 years and examines aspen change patterns with biophysical variables in the Targhee National Forest of eastern Idaho, USA. A subpixel cl...

Forest structural heterogeneity due to species composition, spatial relationships and tree size are widely studied patterns in forest systems, but their impacts on tree function are not as well documented. The objective of this study was to examine how stand composition, tree proximity relationships and tree size influence the leaf functional traits of aspen, an early successional species, and ...

The main purpose of the article is to compare and analyze existing technologies for extracting carbon dioxide from combustion products in relation mini-CHP plants operating on local fuels. presents a brief overview technical features implementation extraction gas mixtures. specific limitations each methods are shown. Mathematical modeling technological processes adsorption, physical chemical ab...

• The ORC system driven by solar energy generates round-the-clock stable power output. integrated is optimized based on a simulation-based optimization framework. Optimal design and control strategy are identified. In this study, the optimal operation of an Organic Rankine Cycle (ORC) investigated. A two-tank sensible thermal storage configured to overcome intermittency energy. circulating flui...

Abstract Ocean Thermal Energy Conversion (OTEC) is a renewable energy source in which produced by converting the heat stored sea or ocean thermal into valuable work, based on temperature difference between warm surface seawater and cold deep seawater. One of OTEC system requirements to have at minimum 20 °C within depth 1000 m below level. Recognizing importance optimum water temperature, sever...

Methyl chloride is the starting raw material for chloromethanes and demand chloromethane increasing steadily in world market. Continuous improvement product quality, reducing cost, improving operation efficiency, minimizing environmental emissions, enhancing process plant safety are some of challenges or constraints facing by industry. In this research work, an attempt has been made to address ...

This work's first aim is to fit the simulated results pilot plant data from Test Centre Mongstad (TCM) for both high and low CO2 exhaust gas inlet concentrations. The next evaluate whether fitted parameters one scenario (a set of experimental under specified conditions) give reasonable predictions other conditions. scenarios at TCM have been in a rate-based model Aspen Plus (RateSep) an equilib...
