Monitoring management criterion of an anaerobic digester using an explicit model based on temperature and pH [PDF]
arXiv, 2017 In this paper, the stability analysis of an anaerobic digestion process is presented. The analysis is performed using a simplified mathematical model, which includes explicit temperature and pH dependence on kinetic growth rates. A detailed nonlinear and bifurcation analyses are performed in order to study the effects of temperature and pH parameters ...

Infrequent adverse event prediction in low carbon energy production using machine learning [PDF]
arXiv, 2020 We address the problem of predicting the occurrence of infrequent adverse events in the context of predictive maintenance. We cast the corresponding machine learning task as an imbalanced classification problem and propose a framework for solving it that is capable of leveraging different classifiers in order to predict the occurrence of an adverse ...

Multiple Sampling Capsule Robot for Studying Gut Microbiome
Advanced Intelligent Systems, EarlyView.A multiple sampling capsule robot (MSCR) is developed for longitudinal gut microbiome analysis. Employing electromagnetic field control, the MSCR can locomote actively, precisely align the selected channel, and collect up to six microbiome samples with minimal cross‐contamination.

Gut microbiota–derived short‐chain fatty acids regulate group 3 innate lymphoid cells in HCC
Hepatology, EarlyView., 2022 Abstract Background and Aims Type 3 innate lymphoid cells (ILC3s) are essential for host defense against infection and tissue homeostasis. However, their role in the development of HCC has not been adequately confirmed. In this study, we investigated the immunomodulatory role of short‐chain fatty acids (SCFAs) derived from intestinal microbiota in ILC3

Improvement of anaerobic digestion of sludge
Water Science and Technology, 2004 Anaerobic digestion improvement can be accomplished by different methods. Besides optimization of the process conditions, pretreatment of input sludge and increase of process temperature is frequently used. The thermophilic process brings a higher solids reduction and biogas production, a high resistance to foaming, no problems with odour, better ...

Analysis of a mathematical model of syntrophic bacteria in a chemostat [PDF]
arXiv, 2011 A mathematical model involving a syntrophic relationship between two populations of bacteria in a continuous culture is proposed. A detailed qualitative analysis is carried out. The local and global stability analysis of the equilibria are performed. We demonstrate, under general assumptions of monotonicity, relevant from an applied point of view, the ...
