In case Wrocław, such analyses have been undertaken several times, but view enormous increase sources obtained course wide-ranging rescue research, it worth taking a look at this problem again.

%'e calculate the lifetime of a nonequilibrium electron in the first excited subband in the lowdensity heterostructure where this photocreated carrier occurs at the last stage of its cooling. The electron interaction with acoustic phonons gives the dominant intersubband relaxation mechanism, if the intersubband energy splitting and the Fermi energy splitting are relatively small, 1 ) e&/Azo ) 0...

We evaluated the potential interaction of pesticide effect and predatory fish on behavior and mortality of a stream mayfly. Experiments in laboratory stream microcosms compared the activity, drift, and mortality of Baetis mayfly nymphs in the absence of fish with that in the presence of Cape galaxias (Galaxias zebratus), both species inhabiting the same stream environments in the Western Cape o...
