Composite soils from conventional tillage (CT) and no-till (NT) fields under wheat (Triticum vulgare cultivar Dogu-88) were randomly collected (0-30 cm depth) in triplicate at 1, 5, 10, 15, 20 and 25 km distance to evaluate the effects of cement dust on soil basal respiration, microbial populations, enzyme activity and calculated soil quality (SQ) indices. Soil pH, exchangeable Ca and Mg, CaCO₃, and...
A method for analysis of the global stability of dynamic systems with pulse-width modulation that are presented in the form of Poincaré mappings is suggested. The method has enhanced efficiency from the viewpoint of the required computing time. Results of this work can be used for automatic analysis and design of these systems.
