The composting is one of the most effective recycling method of green waste. The presence of some heavy metals as Cr2+, Cu2+, Mg2+ and Zn2+ may influence the compost quality. Thus, by adding some components like manure the micronutrients and heavy metals regime suffer changes which might influence their bioavailability for plant uptake. The bioavai...

Electronic properties of pulsed laser deposited, nanoscale CeNi5 alloy layers, on a dielectric substrate are described using the complex dielectric function. This spectral behaviour is studied separately for the real part ε1 (the dielectric constant or dielectric permittivity) and imaginary part ε2 (the dielectric loss function) of ...
