Chemie Ingenieur Technik, EarlyView.A nonlinear kinetic model was developed and successfully implemented, which describes the degradation of the protein C‐phycocyanin depending on temperature and pH value. C‐phycocyanin had been extracted from two different cyanobacteria. In addition to protein degradation, the fading of the typical blue color of this protein was included in the model ...

An Analytical Design Model of a Vacuum Pressure Swing Adsorption Process for Biogas Upgrading
Chemie Ingenieur Technik, EarlyView.A steady‐state model was developed for a vacuum pressure swing adsorption (VPSA) process comprising adsorption, depressurization, and evacuation steps. The resulting analytical plant design model provides the optimal adsorber height required to achieve a target product purity with maximum bed utilization.

Deep Underground Science and Engineering, EarlyView.The effects of grout strength and thickness on the shear behavior of bolt–grout interfaces (BGI) under constant normal stiffness conditions are investigated. Shear strength, failure modes, and acoustic emission characteristics are examined. The findings reveal that grout strength exerts a significantly greater influence on BGI shear strength and ...

Extended Minimal Atomicity through Nondifferentiability: A Mathematical-Physical Approach
Advances in Mathematical Physics, 2019 The mathematical concept of minimal atomicity is extended to fractal minimal atomicity, based on the nondifferentiability of the motion curves of physical system entities on a fractal manifold.

Deep Underground Science and Engineering, EarlyView.The fused data extracted from the distributed monitoring system as the data basis, combined with dynamic geological data, are imported into a deep learning model. As the geological conditions of mining and excavation change, the risk of water inrush at the working face is retrieved in real time.
