Dusts generated in the laboratory from soils and sediments are used to evaluate the emission intensities, composition, and environmental and health impacts of mineral aerosols.
By introducing or selectively altering the existing rate of terpene emission and composition, plant breeders could enable attacked plants to attract enemies and reduce additional herbivory, without compromising the effectiveness of other modes of defence.
Both R and Q values were calculated for model predictions on the original data matrix as well as for 20 random orderings of the Y (health outcomes) data matrix, while keeping the X-matrix (emissions sample composition) fixed.
There is a need to evaluate both the change [relative to baseline (uncontrolled) DEE emissions] in composition and health hazard of emissions as new technologies emerge.
Nevertheless, minor differences in insect feeding choices were found, which may have been related to the changes in leaf volatile emission and metabolite composition in the NE genotype.
The detected minor differences in insect feeding in choice experiments and field bioassays may be related to the revealed changes in leaf volatile emission and metabolite composition between the IE and NE poplars.
Despite of that C. populi slightly preferred IE over transgenic NE poplars, which might be due to alterations we reveal in leaf volatile emission and metabolite composition between the poplar genotypes.
However, this trend reversed itself in the years between 2000 and 2005, during which technical effects contributed significantly to increasing CO2 emissions, whereas industrial composition effects contributed significantly to reducing CO2 emissions.
Trace levels of oxygen suppress gas emission, and gas compositions reflect equilibrium control.
As the vehicle exhaust leaves the tailpipe, the sharp drop in temperature and relatively high concentrations leads to significant condensation of vapor emissions, making particle composition a complex mixture.
