Robert Golan,Donald Edwardsosite mono-nucleus with . = . + . and . = . + ., is likely to occur. Thus the fusion cross section at above-barrier energies is close to the geometric cross section. This is true, however, only for the collision of light and medium-mass nuclei (or low-mass nuclei with heavy ones). As the mass of the

Xiaohua Hu,Nick Cercone,Jiawei Han as well as soil levels. The role of trace elements, copper among others, in soil chemical changes is still a matter of detailed studies. Primary copper-bearing minerals and their secondary weathering stage compounds should potentially release Cu via CO. injection into deep geological structures or

Jan M. Żytkowe carefully maintained and preserved. It is also a key factor for sustainable agriculture, through which numerous impacts can more or less directly affect human activities and even pose serious threats to human health. Heavy metals are ubiquitously present in all soils, although their concentrations
