@unpublished{13629, abstract = {{Plant-based meat alternatives continue to gain market relevance due to sustainability, ethical, and health considerations. However, replicating the texture, cohesion, and sensory attributes of animal-derived meat remains a major technological challenge. Microbial transglutaminase (mTGase), an enzyme that catalyzes covalent cross-linking between glutamine and lysine residues in proteins, has emerged as a promising structuring tool for improving protein network formation in plant-based systems. Produced via microbial fermentation, mTGase is calcium-independent and active across a broad range of food-processing conditions. This review summarizes the mechanism of action of mTGase, its reactivity toward major plant protein sources, and its functional role in comminuted, emulsified, and structured plant-based meat products. Particular emphasis is placed on the integration of mTGase with physical structuring technologies such as extrusion and shear-cell processing.

The vertical water renewal was faster during bottom intrusions from the mainstream than during middle and surface intrusions. At times, the epilimnion contained old water due to circulations, and the hypolimnion contained young water due to upstream flushing. In contrast to natural lakes, the bottom water was often younger than overlying intermediate waters.

In temperate regions, it is challenging to quantify the impacts of deforestation on the catchment dynamics and downstream aquatic ecosystems such as reservoirs and disentangle these from direct climate change impacts, let alone project future changes to inform management. Here, we tackled this issue by investigating a unique catchment-reservoir system with two reservoirs in distinct trophic states (meso‑ and eutrophic), both of which drain into the largest drinking water reservoir in Germany. Due to the prolonged droughts in 2015–2018, the catchment of the mesotrophic reservoir lost an unprecedented area of forest (exponential increase since 2015 and ca. 17.1% loss in 2020 alone). We coupled catchment nutrient exports (HYPE) and reservoir ecosystem dynamics (GOTM-WET) models using a process-based modeling approach. The coupled model was validated with datasets spanning periods of rapid deforestation, which makes our future projections highly robust. Results show that in a short-term time scale (by 2035), increasing nutrient flux from the catchment due to vast deforestation (80% loss) can turn the mesotrophic reservoir into a eutrophic state as its counterpart. Our results emphasize the more prominent impacts of deforestation than the direct impact of climate warming in impairment of water quality and ecological services to downstream aquatic ecosystems. Therefore, we propose to evaluate the impact of climate change on temperate reservoirs by incorporating a time scale-dependent context, highlighting the indirect impact of deforestation in the short-term scale.

Drawing from risk perception theory, we examine how access-based services, as an alternative to ownership, can mitigate perceived risk dimensions. An experimental study reveals that, in contrast to consumers with higher income, low-income consumers perceive access-based services to entail less financial risk, resulting in a greater inclination to access a good than to own it. In a second study, we explore these differences by comparing access with a risk mitigation strategy.

Five clonal Chinese hamster ovary cell populations were analyzed based on the data of a 3-month-stability study. We adapted a mechanistic cell culture model to the experimental data of one such clonally derived cell population. Uncertainties and prior knowledge concerning model parameters were considered using Bayesian parameter estimations. This model was used then to define an inoculum train protocol. Based on this, we subsequently simulated the impacts of differences in growth rates (±10%) and production rates (±10% and ±50%) on the overall cultivation time, including making the inoculum train cultures; the final production phase, the volumetric titer in that bioreactor and the ratio of both, defined as overall process productivity. We showed thus unequivocally that growth rates have a higher impact (up to three times) on overall process productivity and for product output per year, whereas cells with higher productivity can potentially generate higher product concentrations in the production vessel.}}, author = {{Hernández Rodriguez, Tanja and Morerod, Sophie and Pörtner, Ralf and Wurm, Florian M. and Frahm, Björn}}, booktitle = {{Bioprocess Systems Engineering Applications in Pharmaceutical Manufacturing}}, isbn = {{978-3-0365-5210-1}}, issn = {{2227-9717 }}, keywords = {{clonal cell population, phenotypic diversity, inoculum train, uncertainty-based, cell culture model, biopharmaceutical manufacturing}}, pages = {{49--74}}, publisher = {{MDPI}}, title = {{{Considerations of the impacts of cell-specific growth and production rate on clone selection – a simulation study}}}, doi = {{10.3390/pr9060964}}, volume = {{special issue}}, year = {{2021}}, } @inbook{6910, abstract = {{AI is on the rise. Powerful cloud platforms and networked software components can perform increasingly complex data evaluations and simulations. Recent research and development projects1 show how great the potential of artificial intelligence is for urban planning. However, despite the impressive, technical possibilities, it currently remains unclear how planning stakeholders and the affected population can be meaningfully involved in the intelligent processes of the "black box". The authors are of the opinion that sustainable urban development planning not only requires acceptance of the spatial planning result, as has been the case up to now, but also requires acceptance of the increasingly digitally supported planning process. For this reason, it must also be possible for laypersons to understand the digital analysis and evaluation processes and to comprehend their relevance and spatial interactions. Consequently, simulations must not only run in the computers of the respective planning or engineering offices, but require a simple, haptic analog translation that can also be used in participation processes as already shown in the CityScope projects2. For this project, the big revitalization project of Deutzer Hafen in Cologne to a future district with more than 9.500 daily users is used as a case study in building a decision support system for urban planning. It is composed of three parts: an agent-based model, a tangible user interface and a synthetic population. The project enables users to get in touch with an agent-based model (ABM) without any knowledge in coding or even interacting with computers. It connects physical objects to digital information. Based on the theories of Castiglione et.al.3 , Gehl4 , Shannon5 and Jacobs6 this project shows how to use an artificial and analog simulation model to measure the urban vitality of the public spaces in the district, based on the activity and travelling patterns of the population. This is done by testing different scenarios in which we change interactive parameters of the model: the use of the buildings and the demographics of the population. We can then determine which scenarios benefit the most life in the public spaces of the district, by finding areas of interest or problematic ones. }}, author = {{Barbosa Jardim, Amanda and Müh, Maximilian and Häusler, Axel and Kondziela, Andrea}}, booktitle = {{ REAL CORP 2021: Cities 20.50, creating habitats for the 3rd millennium, smart - sustainable - climate neutral : proceedings of 26th International Conference on Urban Planning, Regional Development and Information Society}}, editor = {{Schrenk, Manfred and Popovich, Vasily V. and Zeile, Peter and Elisei, Pietro and Beyer, Clemens and Ryser, Judith and Stöglehner, Gernot}}, isbn = {{978-3-9504945-0-1}}, keywords = {{mart Cities, Agent-based modelling, KI/AI, Participation, Tangible Data}}, location = {{Wien}}, publisher = {{CORP - Competence Center of Urban and Regional Planning}}, title = {{{Synthetic and Tangible Agents for an Activity-based Urban Planning Tool}}}, doi = {{10.48494/REALCORP2021.1049}}, year = {{2021}}, } @inbook{3349, abstract = {{Model-based concepts and simulation techniques in combination with digital tools emerge as a key to explore the full potential of biopharmaceutical production processes, which contain several challenging development and process steps.

Challenges like complex cell metabolism, batch-to-batch variation, variabilities in cell behavior, and influences of changes in cultivation conditions necessitate adequate digital solutions to provide information about the current and near future process state to derive correct process decisions. For this purpose digital seed train twins have proved to be efficient, which digitally display the time-dependent behavior of important process variables based on mathematical models, strategies, and adaption procedures. This chapter will outline the needs for digitalization of seed trains, the construction of a digital seed train twin, the role of parameter estimation, and different statistical methods within this context, which are applicable to several problems in the field of bioprocessing.
