Scientists have estimated that outdoor air quality is leading to millions of premature deaths especially in east and south Asia as a result of emissions of damaging microscopic particles into the air that penetrate deep into the lungs.
This yielded estimates of intercept, slope and significance level of the regression of ion intensities (as a measure of emission) on damage level (which corresponds to a given number of larvae used to create this damage to the cabbage plant).
1987: MONTREAL - Governments adopt a treaty pledging to restrict emissions of chemicals damaging the ozone layer.
To quantify the feeding differences among herbivore treatments in relation to volatile emission, we calculated the number of damaged leaves and number of lesions as observed in each treatment.
The effects of hydrolytic ageing on the acoustic emission signature of damage mechanisms occurring during tensile tests on a glass fibre reinforced polyester composite are investigated.
We found a significant positive correlation between total volatile emission and the two parameters: number of damaged leaves and number of lesions (R = 0.603, p = 0.005 and R = 0.735, p = 0.0002, respectively), as well as a significant correlation between these two damage parameters (R = 0.739, p = 0.0002).
But at the moment, EU energy policy is boosting usage of the most polluting fuel, increasing carbon emissions, damaging the creditworthiness of utilities and diverting investment into energy projects elsewhere.
In the United States, black carbon emissions are indirectly monitored and minimized through federal and state programs that limit small particulate emissions, a category of particles damaging to human health that includes black carbon.
With visual inspection and acoustic emission, three modes of damage and failure process for patch repaired specimens were identified.
Our results also showed increased emission of VOCs in tomato plants damaged by VEGI caterpillars compared to plants damaged by VEGA caterpillars or mechanically injured plants.
