this paper investigates the impacts of economic and financial developments on environmental pollution for 6 opec countries using panel cointegration and panel long-run estimator (dols) over the period 1980–2008.  the results shows that both economic and financial development have significant effect on the environmental quality in selected opec economies. the findings not support the existence o...

Annoyance and sleep disturbance are generally accepted effects of environmental noise. Traffic noise is the most important source of noise induced annoyance. Long-term derogation of the recovery function of sleep by traffic noise has the potential to increase the sensitivity to daytime noise annoyance as well as the risk of cardiovascular and several other diseases. Noise induced arousal and se...

Environmental conditions and airborne myco£lora were measured concurrently in 10 turkey confinement houses during warm and cold weather. The following variables in the environment were measured: numbers of feedand litter-associated yeast and mold fungi, temperature, relative humidity, airspeed, carbon dioxide and ammonia concentration, airborne bacteria, and airborne particulate mass, particle ...

The exchange constant in a magnetic system results from the overlap of orbitals, so it depends upon the ion distance and yields a coupling with the lattice vibrations: this can strongly influence the statistical mechanics of magnets. As the fast lattice dynamics allows for a rapid thermalization, phonon-induced spin correlations can be reasonably neglected, so that phonons can be regarded as a ...

Biomarker research does not exist in isolation. Its usefulness can only be realized when it is translated into prevention strategies to protect public health. In the context of air toxics, these prevention strategies begin with the development of regulatory standards derived from risk assessment schemes. The Clean Air Act Amendments of 1990 list 189 air toxics, including many volatile organics,...
