This work presents the results of on determination a pollutant in model solution, antibiotic cefotaxime, using spectrophotometric method. In several series experiments, minimum concentrations cefotaxime solutions that can be detected with spectrophotometer PE-5400 UV were established; feature was revealed - increase optical density peak samples when pH is shifted to an acidic environment, espec...

in this study, a cross-docking system is designed at strategic and tactical levels. for making the strategic decisions, a multi-objective nonlinear location allocation model for cross-docks is presented based on a distri-bution location allocation model by andreas klose and andreas drexl. the model is further developed to in-clude the whole supply chain members and the objective functions are w...
