Biogas production involves the complex process of anaerobic digestion in bioreactors. This paper presents numerical modeling results and analysis of bioreactors. We discuss research methodology, model geometry, internal bioreactor processes, and possible modifications. Two mathematical models and their …

Background & aims:  Low muscle mass and -quality on ICU admission, as assessed by muscle area and -density on CT-scanning at lumbar level 3 (L3), are associated with increased mortality. However, CT-scan analysis is not feasible for standard care. Bioelectrical impedance analysis (BIA) assesses body …
