in this research, modeling of limiting flux in membrane filtration of skimmed milk as well as the results of simulation by matlab is presented. the presented model is actually a force balance approach and consists of drag, gravitational and lift forces, and forces between colloidal particles (electrostatic repulsive and van der waals attractive forces). to consider the back diffusion phenomenon...

This paper presents a generalized Noortman and Van Es’ empty trips model that considers commodity groups vehicle types. The allows the analyst to quantify contribution of by various types commodities. was validated using data collected in Colombia as part national Freight Origin-Destination Survey. results reveal not all commodities generate similar proportions, require specialized equipment ar...

During the last years a new generation of process-aware information systems has emerged, which enables process model configurations at buildtime as well as process instance changes during runtime. Respective model adaptations result in large collections of process model variants that are derived from same process model, but slightly differ in structure. Generally, such model variants are expens...

Caspase-3, one of the dominant effectors caspases, is activated in almost every model of apoptosis with various signaling pathways. Hence, inhibition of caspase-3 has become an attractive target in the treatment of neurodegenerative diseases. Caspase-3 inhibitory activities of some 1,2-benzisothiazol-3-one derivatives were modeled by quantitative structure–activity relationship (QSAR) using ste...
