Within the framework of independent particle approximation, optical activity tensor solids is formulated as from different contributions: magnetic dipole, electric quadrupole, and band dispersion terms. The first two terms have similar counterparts in theory finite systems, while last term unique for crystals. dipole quadrupole transition moments are calculated with a sum-over-states formulatio...

Adoption of sustainable tillage can protect soils from biological degradation and maintain soil quality, as compared with conventional management. This paper presents findings from a long-term tillage experiment carried out in Endocalcari-Endohypogleyic Cambisols on a sandy loam soil in Lithuania. The tillage systems were: conventional (CT), moderate (MT), and no tillage (NT). Tillage intensity...
