Taking the transdisciplinary research study “Green fingers for a climate resilient city”, funded by the German Ministry of education and research (BMBF), as an example, this paper follows the hypothesis that processes of landscape planning and designing multifunctional green spaces and processes of co-creation need to be combined to stimulate climate resilient city transformation. The findings are that efforts to combine these processes benefit from making complex climate-resilient city planning accessible for people of different professional backgrounds. The paper showcases how storytelling (Schmidt 2019), mapping (Langner 2009) and guided walks (Schultz 2019) are means to mutually engage with, perceive and understand multifunctional green spaces, inspire ownership, and build capacity for the city’s climate-resilient transformation.

Venous leg ulcers and diabetic foot ulcers are the most common chronic wounds. Their prevalence has been increasing significantly over the last years, consuming scarce care resources. This study aimed to explore the performance of detection and classification algorithms for these types of wounds in images. To this end, algorithms of the YoloV5 family of pre-trained models were applied to 885 images containing at least one of the two wound types. The YoloV5m6 model provided the highest precision (0.942) and a high recall value (0.837). Its mAP_0.5:0.95 was 0.642. While the latter value is comparable to the ones reported in the literature, precision and recall were considerably higher. In conclusion, our results on good wound detection and classification may reveal a path towards (semi-) automated entry of wound information in patient records. To strengthen the trust of clinicians, we are currently incorporating a dashboard where clinicians can check the validity of the predictions against their expertise.
Knowledge of the small-scale nutrient status of a field is an important basis for decision-making when it comes to optimising the fertiliser use in crop production. Currently, the traditional method involves soil sampling in the field and soil sample analysis in the laboratory as two separate working processes.
The previous research project "soil2data" developed a mobile field laboratory for different carrier vehicles. In the follow-up project "prototypes4soil2data", the results of soil2data are further developed. A mixed soil sample is collected during the drive on the field. The soil sample is then wet-chemically prepared and analysed. The overall soil sampling and analysis process is divided into the following process steps: soil sampling planning, soil sampling, soil preparation, soil analysis and data management. The process steps are modified for the mobile field laboratory and the process steps run in parallel. The new soil extraction method is based on official German methods (VDLUFA) to ensure the interoperability of the analysis results with the VDLUFA fertiliser recommendations. An innovative key component is the NUTRISTAT analysis module (lab-on-chip with ISFET measurement technology). It can measure pH, the nutrients NO3-, H2PO4-, K+ and the electrical conductivity. In addition to the advantages of rapid data availability and no need to transport soil material to the laboratory, it provides a future basis for new application, e.g. verification of current results in the field during soil sampling with existing results or dynamic adjustment of soil sampling during work in the field.
Hintergrund: Instrumentalisten leiden häufig unter spielbedingten (neuro-) muskuloskelettalen Erkrankungen. Diese zeigen sich bei Streichern, wie Violinisten, Bratschisten und Cellisten, am häufigsten in Form von Beschwerden im Oberkörper – insbesondere im Schulter-Nacken-Bereich. Die apparative Bewegungsanalyse hat sich bereits als hilfreich bei der Beurteilung von muskuloskelettalen Erkrankungen und schädlichen Bewegungsmustern erwiesen und wird für die Diagnostik bei funktionellen Störungen empfohlen. Es wurde bereits gezeigt, dass die apparative biomechanische Bewegungsanalyse ein valides und klinisch praktikables Werkzeug für die genaue und objektive Untersuchung von Bewegungen bei Streichern ist, jedoch ist ihr Einsatz in der klinischen Konsultation immer noch sehr unüblich. Aus diesem Grund existiert ein Mangel an gut etablierten Bewegungsanalyse-Protokollen zur Untersuchung funktioneller Störungen bei Streichern unter Einsatz biomechanischer Instrumente in einem klinischen Umfeld wie der Physiotherapie.
Ziel ist es daher, die Entwicklung und Anwendung eines solchen Protokolls vorzustellen für die Beurteilung der funktionellen Spielbewegungen des Oberkörpers bei sowohl hohen als auch tiefen Streichern in einem physiotherapeutischen Umfeld.
Methode: Zunächst wurden auf Basis einer klinischen Fragestellung relevante Symptombereiche und Messparameter bestimmt. Anschließend wurden beteiligte Segmente, Gelenke und Muskeln selektiert. Darauf basierend wurde ein umfassendes (mechanisches) Modell des Oberkörpers sowie die dazugehörigen Koordinatensysteme und Rotationssequenzen definiert. Dies lenkte sowohl die Spezifikation eines speziell angefertigten Marker-Sets sowie fortgeschrittener Ansätze wie zur funktionellen Bestimmung von Gelenkzentren und -achsen, als auch die Auswahl und Platzierung von Oberflächenelektroden. Schließlich wurden Aktivitäten zur Kalibrierung und Untersuchung der Bewegungsfunktion sowie relevante Analyseparameter und deren Darstellungsformen festgelegt.
Die Protokolldurchführung beinhaltet zunächst die Auswahl der zu untersuchenden Segmente, Gelenke und Muskeln ausgehend von einer oder mehreren klinischen (Arbeits-)Hypothesen bzw. von den spezifischen Symptombereichen. Darauf basierend werden die benötigten Marker und Oberflächenelektroden konfiguriert und platziert. Anschließend werden die festgelegten Kalibrierungsmessungen und Bewegungsaufgaben durchgeführt. Schließlich werden die relevanten Ergebnisparameter zur Überprüfung der Hypothesen extrahiert.
Der klinische Einsatz der Methode wird exemplarisch anhand einer Violinistin mit spielbedingten Schmerzen erläutert.
Klinische Implikationen: Die potenzielle Anwendung des vorgestellten Vorgehens ist die intra-individuelle Evaluation von gleichzeitig der Gelenk- als auch der Muskelfunktion bei hohen und tiefen Streichern während der physiotherapeutischen Konsultation. Dies soll sowohl zur Diagnose funktioneller Erkrankungen des Bewegungsapparates in Form einer objektiven, umfassenden und dennoch klinisch praktikablen diagnostischen Untersuchung als auch zum prä-post-interventionellen Vergleich beitragen.
Applications of pulsed electric fields for processing potatoes: Examples and equipment design
(2022)
In the last two decades, pulsed electric fields (PEF) have successfully been introduced into the food industry, as one of the most promising and "game changing" technologies. This review is devoted to the recent applications of pulsed electric fields used in processing potatoes. The potato processing market size was estimated to be ca. USD 24.83 billion (2018) and with an annual growth rate of 5.2%. The physicochemical characteristics of potatoes and the specificity of potato processing lines makes a pulsed electric field very versatile and flexible allowing one to achieve different technological aims by its implementation into technological lines. In this paper, a short analysis of the potato structure and its nutritional properties, applications of moderate electric fields, ohmic heating, and pulsed electric fields are presented. Moreover, the basic electroporation effects, metabolic responses, texture modification and different PEF assisted processes applied to the potato are discussed. Finally, some examples of commercial applications and a brief description of the available equipment for the PEF processing of potatoes are presented.
Aus dem Brutschrank ins Gewächshaus – Bewertung des Stickstoffhaushalts in Substraten (Abstract)
(2022)
Diabetic foot ulcer (DFU) is a chronic wound and a common diabetic complication as 2% – 6% of diabetic patients witness the onset thereof. The DFU can lead to severe health threats such as infection and lower leg amputations, Coordination of interdisciplinary wound care requires well-written but time-consuming wound documentation. Artificial intelligence (AI) systems lend themselves to be tested to extract information from wound images, e.g. maceration, to fill the wound documentation. A convolutional neural network was therefore trained on 326 augmented DFU images to distinguish macerated from unmacerated wounds. The system was validated on 108 unaugmented images. The classification system achieved a recall of 0.69 and a precision of 0.67. The overall accuracy was 0.69. The results show that AI systems can classify DFU images for macerations and that those systems could support clinicians with data entry. However, the validation statistics should be further improved for use in real clinical settings. In summary, this paper can contribute to the development of methods to automatic wound documentation.
There are a number of well-established concepts explaining decision-making. The sociology of wise practice within public administration suggests that thinking preferences like the use of intuition form a cornerstone of public administrators’ virtuous practice. This contribution uses conceptual and theoretical resources from the behavioral sciences and public administration to account for individual level differences of employees with regard to thinking preferences in the public sector. Institutional frameworks and social structures may enable or impede the habituation of virtue. The contribution empirically investigates this proposition with respondents from North America and the European Union. The analysis investigates the behavioral dimension preference for intuition/preference for deliberation. An analysis of data from 333 employees from organizations in North America and 1644 employees from organizations in the EU reveal prevalent differences in the preference for thinking styles. The public and private sector differ significantly in terms of the preference for rational as well as for intuitive thinking. What is exciting is that private employees rank higher than public employees on both scales, whereas the difference in rational thinking shows a small effect and the effect size in regard of intuitive thinking is negligible. We explore possible explanations for such differences and similarities.
One challenge of the EU energy transition is the integration of renewable electricity generation in the distribution system. EU energy law proposes a possible solution by introducing “citizen energy communities” (Directive 2019/944/EU) which may be open for “cross-border participation”. This article proposes an innovative way of implementing such cross-border communities by linking distribution systems via a “switchable element”, a generation, storage, or consumption asset with a connection to each country. An optimization model has been developed to calculate the system cost savings of such a connection. Linking regions with complementary characteristics regarding electricity generation and demand via a switchable element leads to more efficient system utilization. Findings are relevant for the transposition of “citizen energy communities” in national laws.
