Although the positive effect of elevated CO(2) concentration [CO(2)] on plant growth is well known, it remains unclear whether global climate change will positively or negatively affect crop yields. In particular, relatively little is known about the role of hormone pathways in controlling the growth responses to elevated [CO(2)]. Here, we studied the impact of elevated [CO(2)] on plant biomass...

The combustion behavior of biomass as a fuel varies dependent on source the raw material, but also type pre-treatment. In this work steam exploded and torrefied woody were studied with respect to NOx formation in co-firing experiments. Most reported data is based small scale experiments simulations. work, however, have three different cases been investigated experimentally 1.5MWth combustor sup...

Biomass energy is one of the most accessible and readily available carbon-neutral options as a RES. It regarded viable alternative fuel for coal combustion, particularly biomass co-firing with pulverized coal, numerous applications. The CFD can provide reasonably accurate solutions to complex thermo-chemical-fluid interactions, which useful understanding design or retrofit boilers save time, mo...

Both resistance and tolerance, which are two strategies that plants use to limit biotic stress, are affected by the abiotic environment including atmospheric CO(2) levels. We tested the hypothesis that elevated CO(2) would reduce resistance (i.e., the ability to prevent damage) but enhance tolerance (i.e., the ability to regrow and compensate for damage after the damage has occurred) of tomato ...

The 14C method is an approach used to determine the proportion of carbon derived from biomass and fossil fuel in co-fired flue gas. Its accuracy mainly limited by deviations between applied fuels’ activity reference value virtual value. To enrich theoretical basis when a Chinese coal co-firing power station, this study performed field sampling experiments established new evaluation based on dom...

the distribution and abundance of high aquatic plants in the gorganroud river was examined at five stations in four seasons (20 samples) over one year period during 2009-2010. we identified 21 species of aquatic plants from 21 genera, belonging to 9 families. these species were determined as 3 halophytic species (14.2%) and 18 high aquatic plants (85.7%).the highest species diversity was observ...
