Trotz der zunehmenden Bedeutung eines Betrieblichen Gesundheitsmanagements (BGM) existieren insbesondere an kleinen und mittleren Regionalflugh{\"a}fen bislang wenig systematische und arbeitsplatzspezifische Gesundheitskonzepte. Die Anforderungen an Gesundheit und Einsatzf{\"a}higkeit der Flughafenfeuerwehren werden zudem durch die Vorgaben der Europ{\"a}ischen Agentur f{\"u}r Flugsicherheit (EASA) maßgeblich mitbestimmt. Ziel dieser Arbeit war es, das Belastungs- und Bedarfsprofil der Flughafenfeuerwehr am Airport Weeze zu erfassen und darauf basierend ein ganzheitliches und EASA-konformes Maßnahmenkonzept zur Gesundheitsf{\"o}rderung und Erhaltung der Einsatzf{\"a}higkeit zu entwickeln. Methode: Die Untersuchungen erfolgten im Rahmen eines Mixed-Methods-Designs. Insgesamt 28 der 37 angestellten Einsatzkr{\"a}fte wurden mittels eines teilstandardisierten Fragebogens zu physischen und psychischen Belastungsfaktoren, Trainings- und Erholungsverhalten sowie der Akzeptanz und den W{\"u}nschen zu gesundheitsbezogenen Maßnahmen befragt. Erg{\"a}nzend wurde eine systematische Dokumenten- und Umfeldanalyse sowie eine SWOT (Strengths, Weaknesses, Opportunities, Threats)-Analyse durchgef{\"u}hrt, um strukturelle Ressourcen, Barrieren und Entwicklungspotenziale zu identifizieren. Ergebnisse: Die Auswertung zeigt eine heterogene Alters- und Diensterfahrungsstruktur. Belastungsschwerpunkte wurden im Dienst durch Schichtdienst, L{\"a}rmexposition und sitzende T{\"a}tigkeiten verzeichnet. Gleichzeitig existieren L{\"u}cken in der Erfassung psychischer Belastungen und in der systematischen Dokumentation des Dienstsports. Dar{\"u}ber hinaus wurde festgestellt, dass bislang keine einheitlichen Trainings- oder Testungsverfahren f{\"u}r den Dienstsport vorhanden sind, sodass die k{\"o}rperliche Leistungsf{\"a}higkeit der Einsatzkr{\"a}fte nicht regelm{\"a}ßig {\"u}berpr{\"u}ft oder gezielt gef{\"o}rdert wird. Die Einsatzkr{\"a}fte {\"a}ußerten ein hohes Interesse an strukturierten Trainings-, Resilienz- und Teammaßnahmen sowie den Bedarf an niederschwelligen Unterst{\"u}tzungsangeboten. Jedoch wurde eine geringe Bereitschaft zur aktiven Mitgestaltung verzeichnet. Schlussfolgerung: Auf Grundlage der Analyse wurde ein modular aufgebautes und EASA-konformes BGM-Konzept entwickelt. Das Konzept umfasst eine j{\"a}hrliche sportmedizinische Leistungsdiagnostik, individualisierte Trainingspl{\"a}ne, Peer-Support-Strukturen, Maßnahmen zur Resilienzf{\"o}rderung, Schulungen f{\"u}r F{\"u}hrungskr{\"a}fte sowie partizipative Team- und Kommunikationsformate.

Existing research rarely examines multiple industries together or evaluates competitiveness using both time perspectives, creating a clear research gap. The research question asks how green and traditional companies differ in financial performance, innovation, consumer trust, and regulatory responsiveness. The hypothesis proposes that green companies show lower short-term competitiveness, but higher long-term competitiveness than traditional firms. A qualitative comparative case study approach is applied using secondary data, including annual reports, sustainability disclosures, ESG ratings, and international regulatory frameworks. Six companies are analysed: Tesla and Toyota in the automotive sector, Hilton and Wyndham in hospitality, and Kering and H\&M in fashion. Their competitiveness is assessed through a structured framework that distinguishes between immediate business outcomes and long-term strategic development. The findings show that traditional companies perform better in the short term due to efficient cost structures, established operating models, and stable supply chains. Green companies, however, achieve stronger long-term competitiveness by investing in innovation, transparency, and alignment with tightening regulatory and consumer expectations. Tesla, Hilton, and Kering demonstrate superior long-term performance, while Toyota, Wyndham, and H\&M maintain advantages mainly in the short term. The results support the hypothesis and highlight sustainability as an important driver of long-term competitiveness.

The study addresses how changes in PLA concentration and air pressure influence fibre formation, fibre diameter distribution, and non-woven mat structure, and examines the implications for incorporating tea tree oil(TTO) and pectin into the resulting materials. PLA solutions in DMC were prepared at multiple concentrations, and the SBS process was evaluated using realistic deposition observations and calculated estimates of material consumption. Fibre morphology was analysed by scanning electron microscopy (SEM), revealing fibrous structures and parameter-dependent differences in diameter distributions and mat heterogeneity. Chemical structure was assessed via FTIR spectroscopy, which indicated that the produced fibre mats were dominated by PLA-characteristic spectral features (and possible DMC contributions), while providing limited evidence for substantial pectin or TTO contributions in the measured spectra under the tested conditions. Thermal analysis (STA) was used to interpret important PLA thermal transitions and to identify possible traces of composites within the fibres. A qualitative hydrophilicity approach based on water droplet wetting behaviour was applied as an initial indicator of surface wettability and potential pectin effects, while recognising its limitations compared to full contact-angle measurements. Overall, the results support SBS with DMC as a viable route to produce PLA fibrous mats and show clear process-structure relationships.

Therefore, with the utilisation of probabilistic surrogate models such as Gaussian process regression to reduce the amount of computation necessary. Surrogate models approximate unobserved areas in the design space based on the observed data. Together with the use of acquisition function to select the next observation point, it forms this optimisation method known as Bayesian optimisation. This research aims to implement Bayesian optimisation method in a few test cases involving FEM simulation to compare its performance against conventional methods.

UVA and UVB radiation in particular cause hair to become drier and more porous, making it more prone to structural damage. These effects can be attributed to the breakdown of the hair protein keratin. Suitable in vitro and ex vivo models were used to demonstrate the degradation of hair keratin by UV radiation and to illustrate this visually using real strands of hair. The aim of this work was to develop physically effective protection for hair against UV radiation and to demonstrate the protective effect of such sunscreen products on hair keratin using a specially developed methodology. In line with the current trend toward "skinification" concepts and formulation approaches from facial care were transferred to the hair care sector. For this purpose, a sun protection spray with modern oil-soluble and water-soluble UV filters was developed. Particular attention was paid to the optimal solution of the UV filters in an aqueous O/W emulsion and the subsequent sprayability of the emulsion in order to be able to apply the product evenly to the hair. The aspect of sustainability also played an important role in the selection of raw materials and the manufacturing process. In vitro tests were performed on specially manufactured keratin-containing agarose plates, irradiated with UV light, and then evaluated photometrically using a BCA assay. The samples treated with the product showed a significantly higher keratin content compared to untreated samples, indicating a protective effect against UV-induced keratin degradation. In addition, ex vivo tests on real hair strands confirmed a positive effect of the product treatment on the appearance and feel of the hair. The methodology developed represents an innovative approach to investigating the protective effect of hair sunscreen products on hair keratin and provides a basis for further research and product development.

These nitrogen-containing pigments contribute to stress tolerance and have applications as natural colorants and food supplements due to their antioxidant properties. This study investigated the effect of high salt stress (200mM NaCl) on growth, physiological performance, betalain accumulation, pigment composition, and gene expression in six Amaranth accessions over a 14-day period of exposure. Phenotypic observations revealed visible stress symptoms, such as reduced growth and leaf senescence, whereas physiological parameters such as photosynthesis, stomatal conductance, transpiration, and internal CO2 concentration remain unaffected by salinity. Spectrophotometric quantification showed an increase in betalain concentrations after the 14-day testing period in all genotypes, salt treatment showed minor inconsistent effects. The total betalain concentration was quantified, the results per accession are for Ama 104 3.013 mg/100 g FW, Ama 124 2.944 mg/100 g FW, Ama 154 4.088 mg/100 g FW, Ama 157 4.735 mg/100 g FW, Ama 162 2.227 mg/100 g FW, Ama 169 18.248 mg/100 g FW. Characterization of betalains with HPLC-DAD-MS analysis confirmed the presence of amaranthine and isoamaranthine as the dominant betalain present in Amaranth leaves, which is consistent with the known betalain presence of grain amaranth species; no betaxanthins were detected. Gene expression analysis of CYP76AD2, DODA2, DODAα2, and SOS1 revealed no significant transcriptional induction under salt stress after the 14-day salt stress treatment. These results may suggest that betalain accumulation occurred due to normal developmental regulation rather than a salinity effect. However, analysis 24-48 after salt stress induction is recommended to conclude. The combined results reveal variation in pigment levels and salinity-stress response and demonstrate the resilience of grain amaranth to increased salinity exposure. The variation in pigment accumulation indicates the importance of selecting high-betalain accessions for industrial applications at an early stage. Future research should focus on early transcriptional levels and regulatory mechanisms to better understand stress response in the betalain pathway of these amaranth accessions.}, language = {en} } @misc{Aziz2025, type = {Master Thesis}, author = {Aziz, Sk Tarik}, title = {The Impact of Employee Job Satisfaction on Organization's Long-Term Performance}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-23053}, school = {Hochschule Rhein-Waal}, pages = {266}, year = {2025}, abstract = {The purpose of the study is to investigate the impact of employee job satisfaction on organizational long-term performance and focus on the key factors that increase satisfaction among employees.

To fill this gap, qualitative research was conducted, and data was collected through semi-structured interviews, and the data was analyzed using MAXQDA software. The findings represent some of the factors that significantly increase job satisfaction, such as positive and supportive work environment, flexibility and autonomy at work, career growth and continuous learning opportunities, and fair compensation with meaningful recognition. The participants repeatedly highlighted these factors as a source of enhancing motivation, dedication, commitment, and employee performance.

This situation causes challenges for Strama-MPS, especially in the Global Service division, where long-term spare-parts availability and reliable customer support are required. When components are no longer available, urgent procurement, redesigns under time pressure, longer downtimes and higher service costs put additional load on internal departments and can negatively affect customer relationships. This thesis develops a structured and financially viable approach to obsolescence management for Strama-MPS. The current situation was analysed using expert interviews and SAP and PRO.FILE data for the period 2018 to September 2025. The evaluation of more than 13,000 obsolete materials showed fragmented communication, insufficient lifecycle documentation and that only a few large suppliers systematically send PCN notifications, while many others do not. To summarise the results, a Power BI dashboard was created that shows portfolio age, part criticality, successor availability and supplier concentration. The analysis identified an average part age of 6.75 years, a cost-at-risk of around €1 million and a high-risk group mainly consisting of electrical and control components. In a second step, the active parts portfolio was evaluated to identify future risks. Using manually cleansed Excel files and Power BI models, a lifecycle forecast was developed for the period 2026-2029. It highlights early-warning patterns in connectors, sensors, I/O modules and control units with short technology cycles and high dependency. These results enable earlier evaluation of alternatives, more controlled last-time-buy decisions and more proactive customer communication. Based on these findings, the thesis proposes a target framework in line with DIN EN IEC 62402:2025-05. It defines responsibilities, decision and communication paths, and workflows between the relevant departments. A dedicated Obsolescence Manager is assigned as the central process owner and is supported by SmartPCN-compatible input formats, lifecycle dashboards and an implementation plan that starts with an internal pilot and later includes the roll-out of PCN Global as the OM software. The strategic options were assessed using an MCDA, comparing reactive, proactive and strategic approaches. The results show that a dedicated role combined with suitable software offers a good balance between cost control, early-warning capability and acceptance. The financial analysis indicates that the concept can pay back within the first year by reducing emergency sourcing, redesign work and service delays, while also improving collaboration, decision quality and long-term service performance.

The background of climate change, long supply chains, and growing consumer detachment from food production form the motivation to bring consumers and agricultural producers closer together, especially in urban areas such as D{\"u}sseldorf. Therefore, this study explores which factors influence consumer willingness (intention) and actual purchasing behavior of regional products. The work is based on the Theory of Planned Behavior model (TPB), extended by the additional variable trust and uses a mixed-method approach, which combines literature review, an online survey (n=150), and two semi-structured interviews with local farmers. The statistical results show that attitude, social norms, perceived behavioral control, and trust do not significantly influence regional purchasing intention or actual behavior. The only significant effect can be seen on the willingness to pay higher prices for regional products in different age groups. Older consumers (>36) show significantly higher willingness to pay higher prices than younger consumers (<35). Furthermore, the findings show a clear attitude-behavior gap, where interest or positive attitude towards regional products cannot be translated into real purchasing behavior of regional products. Additional descriptive results show that prices, convenience, and product variety influences grocery choices the most, and social media and recommendations from friends/family are most relevant information sources. Based on these insights, this study develops implications for farmers, consumers, and the city with the goal of strengthening the relationship between local farmers and urban consumers. Key recommendations include hybrid approaches by combining stronger digital visibility with strong personal interaction. Additionally, target group specific actions for younger and older consumers are presented as well as models that combine flexibility with direct exchange such as hybrid CSA.

The designs were mainly focused on the kneading and mixing part of the screw which has a shearing effect on the biopolymer. The experiments were carried out by keeping the temperature, screw speed and feed rate constant. To carry out the experiment, a 60:40 blend of PBAT and PLA was utilized.

It evaluates the extent to which LINEG's EMAS-based environmental disclosures align with CSRD/ESRS and where extensions are required to meet comprehensive ESG obligations. The analysis is grounded in Stakeholder Theory and Valente's Stage Model to connect accountability expectations with organizational sustainability maturity. Methodologically, a qualitative case study and qualitative content analysis are applied to LINEG's EMAS statements and relevant regulatory texts, using deductive categories derived from CSRD/ESRS and SASB, complemented by inductive coding to capture LINEG-specific themes. Peer utilities are referenced to contextualise findings.

However, material gaps remain in social and governance areas (e.g., workforce metrics, affordability and service quality indicators, stakeholder engagement processes, and board-level oversight of sustainability). Applying Valente's model positions LINEG between Defensive and Isolated stages: largely compliancedriven, with initiatives not yet embedded across strategy and governance. The thesis proposes a roadmap to consolidate environmental disclosures into ESRS structures, conduct a double-materiality assessment, expand S and G indicators, formalise stakeholder engagement, and assign clear governance responsibilities.

Notably, heat loss on a large scale at the industrial level has been recognized as neither economically nor environmentally sustainable. Moreover, the continued use of fossil fuels (natural gas) has been reviewed as unsustainable due to their adverse effect and limited availability, posing challenges for the present and future. Heat loss is optimized at the continental production site in Villingen-Schwenningen. Heat loss through exhaust fans, which extract heat from inside the building and release it to the environment to maintain the internal temperature, has been analysed. The released heat is lost in the environment. To recover this energy loss, the integration of a plate-to-plate heat exchanger is proposed. This approach recovers the rejected heat to preheat the incoming fresh air supply, replacing the traditional heat coil operated on natural gas. Additionally, the transition of natural gas to biogas has been explored. The district heating twin pipe (DN 80) is considered for the smooth flow of thermal energy. For this project, a financial analysis of return on investment (ROI) for 10 years is conducted, the thermal energy flow rate over 2.1km, and heat loss during the transfer phase are calculated. The results have shown significant importance for the recovered energy by integration of a plate-to-plate heat exchanger; yearly, 1.2 GW of energy can be recovered, reducing the consumption of natural gas and making a complete transition towards biogas, economically and environmentally beneficial.}, language = {en} } @masterthesis{Floeren2025, type = {Bachelor Thesis}, author = {Fl{\"o}ren, Marie Catherine}, title = {Immersives Erleben Ein Einblick in das Immersionsverst{\"a}ndnis der Anbieter:innen immersiver Besucherattraktionen}, school = {Hochschule Rhein-Waal}, year = {2025}, abstract = {Immersive experiences have been gaining popularity for the past few years within the tourism industry.

Furthermore, it was possible to identify multiple strategies used in immersive experiences, some of which have not yet been found in current research. The interviewed organizers suggest that immersive design will be a trend within the tourism industry.

The work is conducted within a purely model-based framework, employing MATLAB and Simulink to replicate the vehicle dynamics and control interactions in a controlled virtual environment. Torque vectoring describes the distribution of drive torque between individual wheels to influence the yaw moment of the vehicle. This enables targeted improvements in stability, responsiveness, and cornering performance beyond what is achievable with steering input alone. In this study, yaw rate is selected as the primary control variable. A reference yaw rate is derived from the linear bicycle model, and the control objective is to minimize the error between the reference and the simulated actual yaw rate by applying corrective yaw moments through differential torque allocation. A Proportional-Integral-Derivative (PID) controller is implemented to track the reference yaw rate. Gain tuning is performed using MATLAB's PID Tuner, leveraging the system transfer function extracted from the simulation model. The complete control system is integrated into a modular Simulink model of the go-kart, which incorporates the 2-DOF bicycle model for lateral and yaw dynamics, as well as subsystems for maneuver generation and torque vectoring logic. Controller performance is assessed through standard vehicle dynamics test maneuvers, including ramp steer, step steer, and double lane change. For each maneuver, simulations are performed both with and without torque vectoring, allowing quantitative comparison of yaw rate tracking accuracy, stability, and trajectory. The results demonstrate that torque vectoring substantially improves yaw rate tracking and reduces the understeer tendency of the simulated vehicle, particularly during transient maneuvers. Even in a simplified small-scale vehicle model, the benefits of active yaw moment control are evident, underscoring the relevance of torque vectoring for enhancing dynamic performance in electric vehicles with independent wheel actuation.

This study looks at juxtaposing narrative outlining through text with automated visual generation toward an integrated system that produces adaptable comic panels with appropriate visual structure. The research methodology that the project has followed can be built on three cornerstones: advanced GAN schemes for text generation and pre-processing, followed by image synthesis through Stable Diffusion. A specially developed algorithm for speech bubbles determined the optimal placement of that text, so it would function well and maintain a semblance of beauty.

Initial observations regarding visual coherence and narrative alignment were hopeful, but further tests using quantitative metrics-for instance, FID for images and BLEU for text, as well as broader user feedback-would be needed to validate the efficacy of the model entirely.

While origin can impact the development of A. digitata, its impact on the species mycorrhization potential is not well understood, and was investigated in this thesis. A. digitata plants were grown from seeds of semi-arid, sub-humid and humid zone origins of Benin inside a controlled climate chamber. The seedlings from each origin received native soil, commercial mycorrhiza fungi (alternative) and control treatments. Growth parameters were determined before treatments application and at termination. Models combining the effects of treatment, zone origin, unique tree characteristics and block arrangement were used for statistics. Only seedlings of the humid zone origin had significantly higher initial leaf count than counterparts from other origins.

In Germany, the shift from internal combustion engine vehicles (ICEVs) to electric vehicles (EVs) has become a key focus of national and EU climate policies. Nevertheless, the transition to EVs is associated with a multitude of factors that need to be considered, including emissions from manufacturing, the energy used during operations, and post-operational treatment. This thesis focuses on the design, development, and refinement of a web-based CO₂ Lifecycle Emission Calculation tool that compares cradle-to-grave emissions of EVs and diesel ICEVs based on different driving scenarios in Germany. It is based on Life Cycle Assessment (LCA) Methodology as indicated in ISO 14040/14044. With the tool, the manufacturing, operational, and end-of-life emissions are estimated based on validated datasets from peer-reviewed literature and authoritative bodies (IPCC, IEA, UBA). The tool's modular structure, which was developed in Python with the Streamlit framework, also allows for other languages to be added, selection of the region's grid mix, scenario comparisons, and results visualization in multi-level dashboards. Findings of the literature review show that the tool is accurate for both types of vehicles as the known lifecycle emissions ranges for both types are captured. Carbon payback periods for EVs ranged from less than three years to over eight years depending on the grid context, from renewable-rich to coal-intensive. Sensitivity analysis demonstrates that both grid CO₂ intensity and annual mileage hold the greatest influence over lifecycle results. This research contributes to sustainability as it fills the void that exists between academic LCA models and consumer-facing applications with a transparent, reproducible, and user-configurable decision-support tool. Improvements can be made by incorporating real-time grid emission data, expanding the vehicle datasets, and including additional CO₂ environmental impact categories.}, language = {en} } @misc{Tewes, author = {Tewes, Thomas}, title = {Luminescence and Raman spectroscopic data of bacteria with and without exposure to water-soluble polymers (WSPs)}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-22486}, abstract = {Data from luminescence measurements of bacteria exposed to water-soluble polymers (WSPs), as well as Raman spectra of bacteria with and without contact to the WSPs.

W. Erickson and aksimovic 2020). I develop a prototype digital controller for a buck converter, which uses a trained GPR model to predict the PWM duty cycle required to obtain a desired output voltage. I use an Analog Discovery 2 (AD2) (Digilent Inc. n.d.) as an interface between the GPR controller and the buck converter hardware by providing real-time voltage measurements to the controller and generating the PWM signal. I compare the performance of the GPR controller with the TPS629210DRLR Integrated Circuit (IC) (Texas Instruments 2022), which uses an analog control method and serves as the reference performance standard. I compare the performance of the GPR controller and the IC based on their ability to maintain a target voltage during a load change involving an RC load. The results are evaluated based on the voltage regulation accuracy and load voltage settling time. The results show that both controllers are able to set the load voltage within 1\% of the target value. However, the GPR controller has a settling time around 3 times longer than the analog controller. The longer settling time is due to latencies from communication with the AD2 and the time required for duty cycle computation. Despite this, the settling time difference is short enough to consider the digital GPR controller competitive to the reference analog control method, especially since the current prototype is not optimized to reduce these latencies.

Because of this policy, alternative poultry production methods were created to better meet animal welfare guidelines. To meet this challenge, the University of Bonn launched research into dual-purpose chickens, specifically the British Ixworth breed. Integrating male and female chicken farming offers a new, innovative solution to ethical and sustainability issues in traditional farming by combining egg and meat production. The importance of this research for revolutionizing poultry farming cannot be overstated (Becker et al., 2023). A University of Bonn research team is studying this alternative farming method to determine its productivity and viability. To meet industry needs while prioritizing animal welfare, they evaluate dual-purpose chicken potential by analysing egg (number and weight) and meat (weight) yields. This thesis has four sections, exploring different facets of dual-purpose chickens across four generations via diverse statistical and machine learning methods. First, it examines existing research on various facets of analysing and forecasting individual chicken egg and growth data. It further explores Becker et al.'s 2023 study, "The British Ixworth: individual growth and egg production of a purebred dual-purpose chicken." Moreover, the linear regression, SVR, KNN, and decision tree models were applied to this data for advanced analysis and prediction. The thesis's second part details the methodology, including requirements analysis and dataset preparation. This thesis's third section details how data from four generations of chicken life were analysed to predict future egg production and individual chicken growth. Across generations, individual chickens' average body weight and egg weight all showed an increase in the results. Predictions from linear regression and decision tree models show an increase in individual chickens' growth across generations to come. Egg production forecasts were better with the KNN model. This research will use advanced statistical methods and machine learning to model and assess the generational performance of dual-purpose chickens. These tools will forecast future egg and meat production, thus giving key insights to enhance breeding programs. This research aims to optimize dual-purpose chicken production for growth and egg-laying performance.

The study aims to identify an optimal set of parameters that ensures high-dimensional accuracy while maintaining structural integrity. A systematic experimental methodology was adopted, beginning with a full-factorial design to establish baseline parameters for printing temperature (170°C), printing speed (15 mm/s), and nozzle diameter (0.4 mm). A Box-Behnken Design (BBD) was employed to optimize critical parameters, specifically layer height, raster width, and mover levitation height. Analysis of Variance (ANOVA) identified layer height as the most dominant factor influencing dimensional accuracy (p < 0.0001), while raster width and mover levitation had lesser effects. The experimental validation of the optimization results revealed discrepancies between the numerically and empirically optimized parameter sets. Although the numerically optimized settings had a theoretically superior accuracy of 98.29\%, their practical implementation led to structural failures, specifically the collapse of scaffold bridges. In contrast, the empirically optimized set (layer height: 0.2 mm, raster width: 0.45 mm, mover levitation height: 2.25 mm) consistently achieved a mean dimensional accuracy of 97.14\% while maintaining stable printability.

The work employs the dialectical method, drawing on Horkheimer and Adorno's 'Dialectic of Enlightenment' to analyze the contradictory development of gender relations within a seemingly rational and emancipated modernity. The central thesis posits that the ideals of the Enlightenment—devoted to liberty, reason, and equality—dialectically reverse into their opposites. The focus lies on the social role of women, who experience societal subjugation as a result. Through a historical analysis of Early, High, and Late Enlightenment, two structural concepts are identified that emerge from Enlightenment thought: (1) the categorically dichotomized production of knowledge, and the (2) transition from monarchical to physiocratic bourgeois systems. It is shown how a complementarity of the sexes is legitimized on the basis of categorial-dichotomized knowledge production, which is divided into dichotomized social spheres in the sense of an equal society on the basis of their supposedly natural abilities. This creates a dialectical moment that places women in a seemingly natural, but actually ideologically shaped position of subjugation. The third part of the thesis applies Negative Dialectics to deconstruct prevailing gender relations. It questions the foundations of dichotomous knowledge production and explores the compatibility of feminist theories with Critical Theory. Furthermore, it critically engages with identity politics.

Semi-structured interviews were conducted with stakeholders across both countries and thematically analysed according to six key areas: general characteristics, exports and market access, labour conditions, public policy and framework, support framework, and growth potential. Findings suggest that the Dominican Republic's success is due to continued governmental prioritization and support, alongside the presence of strong producer associations that facilitate access to post-harvest infrastructure, international markets, and organic certification. In contrast, Costa Rica's sector remains fragmented, with limited coordination, restricted market access, and minimal governmental support.

The system integrates multiple custom-designed PCBs equipped with many LEDs and sensors, each assigned to individual storage slots. Each storage slot is equipped with an LED and an infrared (IR) sensor. The sensors detect the presence of reels, while the LEDs provide visual guidance for storing or locating specific reels. To manage multiple sensors efficiently, a multiplexing method is used, allowing each Arduino Pro Mini to control up to 16 sensors with fewer pins. Multiple Arduino Pro Mini microcontrollers are deployed across different rack sections and communicate with a central master controller using the RS485 protocol. The master controller, based on an ESP32, connects to an MQTT broker to send and receive data from a storage management system. Users interact with the system through a web interface. When storing a reel, the user scans it into the online system, which then activates an LED to indicate the appropriate storage slot. When retrieving a reel, the system highlights its location via the corresponding LED. Sensors are used to confirm the presence or absence of reels within the slots ensuring accurate tracking of stored items in real time. The system is modular and scalable. In this thesis, the prototype demonstrates two levels of storage racks, each independently controlled and networked, validating the communication between multiple slave units and a master. Additionally, because of the different sizes of the reel, the design includes removable metal dividers between slots. When storing larger reels, dividers can be removed, and this change is also updated via MQTT to the online system. Power is supplied through a 5V, 30A power supply, ensuring stable operation of all electronic components. Overall, the results confirm that the system achieves reliable performance in both hardware and communication aspects, offering a practical and scalable solution for modern electronic component inventory management.}, language = {en} } @misc{DobariyaBockmuehl, author = {Dobariya, Binal and Bockm{\"u}hl, Dirk P.}, title = {Comparative analysis of microbial community on apricot kernel shells and walnut shells influenced by post-harvest conditions.}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-22214}, abstract = {Apricot kernel shells (AKS) and walnut shells (WS) are byproducts from fruit processing lines and may serve as sustainable alternatives to microplastics in industrial applications due to their high content of natural polymers such as cellulose, hemicellulose, and lignin.

This project is intended to create a tool for exploratory/experiential learning - one that allows learners to investigate regional data and pursue genuine learning opportunities. The plan is to use regional data in a specific user journey to create this interactive learning experience. The project uses open environmental data: Hygris dataset of LANUV(Landesamt f{\"u}r Natur, Umwelt und Verbraucherschutz) related to the regions Kleve and Wesel in Germany, and realizes this with help of python programming language and python streamlit framework, web development tools and data visualization libraries (pandas , plotly.express, streamlite.components.v1). This study explores tailored visualization strategies that address key challenges such as the inherent complexity of environmental datasets and the need for more engaging and comprehensible educational tools. These strategies include deploying interactive visualizations that allow hands-on data exploration, and temporal visualizations. The role of user feedback in refining educational tools for teaching environmental data is examined, particularly in designing effective visualization techniques like line char, bar chart, bubble chart, pie chart, scatter plot and intensity graph for representing groundwater nitrate concentrations. The impact of different visualization techniques on the understanding and interpretation of open environmental data among educators and students is analyzed, with an emphasis on the spatial distribution of groundwater nitrate concentrations over time. This approach aims to increase user engagement and deepen understanding of environmental data, facilitating a more profound embedding of information within learners' cognitive processes.}, language = {en} } @masterthesis{Chng2025, type = {Bachelor Thesis}, author = {Chng, Ci Ern Katelyn}, title = {Effects of Sewage Sludge Biochar as a Growing Media Component and Phosphate Fertiliser on the Cultivation of Potted Ornamental Plants}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-22189}, school = {Hochschule Rhein-Waal}, pages = {42}, year = {2025}, abstract = {There is increasing pressure from the German government on its citizens to reduce dependency on phosphate rock and peat, in agriculture and horticulture. This is due to the phosphate rock oligopoly with associated political instabilities, and the environmental consequences of peat harvesting. Past studies on soilless crop cultivation have shown promising outcomes for the phosphorus (P)-rich sewage sludge biochar (SSB) as an answer to these issues. However, SSB remains as one of the least studied biochar types in soilless ornamental cultivation. The objectives of this study were to investigate the viability of SSB as a P fertiliser and growing media component in pot cultivation of lavender (Lavandula angustifolia), purple coneflower (Echinacea purpurea) and poinsettia (Euphorbia pulcherrima). The addition of SSB at a 10\% (v/v) rate to coco peat (SSB 10) was determined as the best composition. Although it did not outperform the control, SSB 10 plants were not significantly lower than the control plants in height, dry aboveground biomass, and number of poinsettia stems across all three species - except in poinsettia biomass. Other rates (5\%, 15\%, 20\%) had significantly lower values in more than one parameter. Physicochemical characterisation also revealed increased P with increasing SSB rates in the growing media. Contrary to other studies, the pH of all growing media did not exceed ideal growing media pH values (5.3-6.5), further solidifying SSB's viability as a growing media component. The reliability of our results could be improved by recording water uptake of the media, and selection of species with quantifiable aesthetics.}, language = {en} } @masterthesis{Rigotti2025, type = {Bachelor Thesis}, author = {Rigotti, Roberta}, title = {Artichoke (Cynara scolymus L.) and climate change: Assessing the potential in German agriculture with insights from Italian practices}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-22178}, school = {Hochschule Rhein-Waal}, pages = {78}, year = {2025}, abstract = {Artichoke (Cynara cardunculus var. scolymus) is a crop loved in the Mediterranean, particularly in Italy, where it has a long tradition holding both cultural and economic value. It has many different uses, from fresh consumption to medicinal use and potential in the energy and cheese-making industry. In northern European countries, such as Germany, artichoke cultivation has not been largely present up until now, mostly due to climate limitations, like very cold winters. However, climate change may offer new opportunities for its introduction. This study wants to assess the viability and potential of artichoke cultivation in Germany under current and future climate conditions, with the support of climate reports and literature sources. Past German trials, together with insights from the Italian artichoke cultivation, are integrated into the analysis to offer a better understanding of potential practices and implications for a future cultivation of the crop in Germany. The study concludes that winter cultivation is unfeasible without proper winter protection practices or the development of reliable frost-resistant varieties. However, annual cultivation with harvest within the same season represents a promising option in most German states. Locally grown artichokes could translate into economic and environmental advantages by answering the increasing interest in fresh, healthy, and regionally sourced products.

We chose a range of bacterial strains, including standard test strains such as Micrococcus luteus and Enterococcus faecium, as well as important foodborne pathogens such as Escherichia coli, Staphylococcus aureus, and Salmonella Typhimurium. To account for the complexity of dishwasher cycles, we correlated hygiene efficacy with area under the curve (AUC) measurements derived from the respective cycle profiles. Our findings revealed that the reductions in M. luteus and E. faecium were minimally affected by the reference detergent. In contrast, a high-tier market detergent demonstrated a significant decrease in bacterial counts. Notably, both strains exhibited reduced efficacy at a main cycle temperature of 45 °C, suggesting that temperatures below 50 °C might represent a critical threshold at which the hygiene efficacy of domestic dishwashing processes declines. However, since food-related pathogens were more susceptible to the dishwashing process, even lower temperatures might deliver a sufficient level of hygiene. Plotting the logarithmic reduction/AUC ratio against the AUC indicated that the main cycle contributed approximately 10-fold more to microbial reduction than the rinse cycle. Furthermore, the antimicrobial impact of detergents was greatest at the lowest AUC values (i.e. during short cycles). Taken together, our results suggest that the main wash temperature, the type of detergent, and the specific strain tested all impact bacterial hygiene performance.}, language = {de} } @masterthesis{Pogrebnyak2025, type = {Bachelor Thesis}, author = {Pogrebnyak, Anna}, title = {Application of the Ant Colony Algorithm for solving routing optimization problem in logistics}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-22135}, school = {Hochschule Rhein-Waal}, pages = {78}, year = {2025}, abstract = {In logistics there are different options of how the Traveling Salesman Problem can be solved.

The laboratory studies explore various operational parameters, such as CO₂ consumption efficiency, pressure variations, and residence time, in order to optimize splitting in various emulsion mixtures. The studies proved to effectively provide up to 95\% total organic carbon (TOC) reduction, particularly achieved in combination with prolonged flotation and settling. Significantly, treatment by CO2-induced separations proved to have most efficiency in synthetic Sodium Lauryl Sulphate (SDS)-based emulsions and in industrial scenarios such as in cooling lubricants. In addition, prolonging flotation time to an overnight timeframe significantly increased TOC reduction in the case of the SDS emulsion. The presented results offer a new look over the experimental development of separation technologies, demonstrating the effective splitting of emulsions by injecting CO2 without additional pressure input and thus its feasibility in an industrial setting.

In light of this, this thesis examines the relationship between corporate taxation and social inequality. The effects of statutory and effective tax rates on both income and wealth inequality (measured by their respective Gini-coefficients) are compared. A panel data regression model was carried out using SPSS. The model was applied to a selection of 10 OECD countries, spanning over a 6-year period from 2017 to 2022. The regression model indicates a significant relationship between income inequality (income Gini-coefficient) and the two corporate tax rates (estimates of -0.332 for statutory and -0.311 for effective). However, a significant relationship between wealth inequality (wealth Gini-coefficient) and the two tax rates was not identified. In addition, limitations regarding heteroscedasticity, potential endogeneity issues, and the small data set were addressed in detail but not completely ruled out. Implications include the effectiveness of progressive corporate taxation as a redistributive tool in the case of income inequality and the investigation of alternative taxes for tackling wealth inequality.

This thesis explores the potential of solar energy as a sustainable solution to address these challenges, focusing on economic, technical, and regulatory barriers while drawing comparative insights from Cyprus's renewable energy model. The research examines three primary questions regarding the economic and technical challenges hindering solar energy adoption in Lebanon, the lessons that can be learned from Cyprus to inform solutions, and the comprehensive strategies that can support the development of Lebanon's solar energy sector. The findings reveal that while Lebanon has experienced rapid growth in solar energy adoption, the sector is undermined by systemic issues such as low-quality imports, skill gaps, insufficient grid infrastructure, and the dominance of diesel generators. Comparative analysis with Cyprus underscores the importance of robust regulatory frameworks, financial accessibility, public-private partnerships, and accreditation systems for solar installers. Additionally, the analysis highlights the critical role of improving capacity factors in Lebanon, with findings showing that even a 1\% increase could supply power to over 16,000 homes, emphasizing the potential efficiency gains for Lebanon's solar energy sector. The thesis also evaluates Lebanon's progress toward its 2030 renewable energy targets, noting that while the country appears to have met these targets in percentage terms, the achievement is largely a result of reduced electricity generation rather than genuine renewable capacity growth. Recommendations include enforcing quality standards, establishing national accreditation systems, addressing corruption, and leveraging international funding for infrastructure modernization and workforce development.

Findings from this thesis can aid policymakers, economists, and business leaders in anticipating future global economic patterns driven by rising emerging economies.}, language = {en} } @masterthesis{Friedrich2025, type = {Bachelor Thesis}, author = {Friedrich, Fabian}, title = {Wie beeinflussen Wertsch{\"a}tzung am Arbeitsplatz, wahrgenommene organisationale Unterst{\"u}tzung und psychologische Sicherheit die Arbeitszufriedenheit, Absentismus und Fluktuation?}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-21694}, school = {Hochschule Rhein-Waal}, pages = {99}, year = {2025}, abstract = {Ziel der vorliegenden Arbeit war es den Einfluss zwischen Wertsch{\"a}tzung am Arbeitsplatz, wahrgenommener organisationaler Unterst{\"u}tzung (POS) und psychologischer Sicherheit mit der Arbeitszufriedenheit, Absentismus und Fluktuationsabsicht anhand einer deutschen Stichprobe zu untersuchen. Es wurde zudem erwartet, dass Wertsch{\"a}tzung eine vermittelnde und moderierende Rolle hinsichtlich der wahrgenommenen organisationalen Unterst{\"u}tzung einnimmt. Dazu fand eine Querschnittsuntersuchung vom 02.12. bis 18.12.2024 mittels Online-Fragebogen statt. Zum Einsatz kamen gr{\"o}ßtenteils bew{\"a}hrte Messinstrumente der quantitativen Forschung. F{\"u}r die Messung des Absentismus in Form von krankheitsbedingten Fehlzeiten wurde ein Item aus der empirischen Forschung gebildet. Zudem wurden demografische Daten (z.B. Alter, Geschlecht, Arbeitszeitmodell) erfasst. Nach Bereinigung der Stichprobe umfasste diese 55 deutsche Teilnehmende im Alter von 20 bis 66 Jahren, wobei 53\% weiblich und 47\% m{\"a}nnlich waren. Es zeigte sich, dass Wertsch{\"a}tzung am Arbeitsplatz isoliert und im Zusammenspiel mit POS einen Einfluss auf die Arbeitszufriedenheit und Fluktuationsabsicht von Mitarbeitenden hat. Des Weiteren konnte Wertsch{\"a}tzung den Effekt von POS auf die Arbeitszufriedenheit partiell vermitteln. Zudem konnte ein signifikanter Interaktionseffekt zwischen POS und Wertsch{\"a}tzung auf den Absentismus gezeigt werden. POS und psychologische Sicherheit konnten isoliert betrachtet einen Einfluss auf die Auspr{\"a}gung der Arbeitszufriedenheit aus{\"u}ben. Aufgrund des geringen Stichprobenumfangs und eingeschr{\"a}nkter Repr{\"a}sentativit{\"a}t sollten die Ergebnisse durch weitere Studien repliziert werden. Die Limitationen der Untersuchung sowie Implikationen wurden in dieser Arbeit diskutiert.}, language = {de} } @misc{SarmientoGonzalez2025, type = {Master Thesis}, author = {Sarmiento Gonzalez, Maria Angelica}, title = {Sustainable commercialization of Baru in the Cerrado: mapping its Value Chain for rural livelihood enhancement}, school = {Hochschule Rhein-Waal}, year = {2025}, abstract = {Land-use transformation and insufficiently protected areas have led to extensive deforestation and conversion of native vegetation for croplands and pastures in the Cerrado, Brazil's second-largest ecosystem and one of the world's biggest biodiversity hotspots. The sustainable harvesting and commercialization of non-timber forest products (NTFPs) offer a potential alternative, contributing to sustainable development by enhancing rural livelihoods, promoting environmental conservation, fostering economic diversification, empowering vulnerable socio-economic groups, and encouraging sustainable resource management. Among Cerrado's promising NTFPs is the Baru nut (Dipteryx alata), a nutrient-dense product rich in protein, fiber, zinc, and healthy oils, with potential therapeutic applications for various health issues. Its unique composition and versatility present an opportunity for sustainable commercialization that enhances rural livelihoods while promoting health benefits. Incorporating Baru-related products into local, national, and international markets could diversify economic opportunities while maintaining environmentally sustainable practices in both production and commercialization. Despite its potential, research on Baru remains scarce, creating a knowledge gap in the dynamics and challenges of its value chain. This study addresses this gap by employing a mixed-methods approach to evaluate the financial performance of each stage of the Baru value chain and identify existing challenges and market opportunities. Focused on Arinos, Minas Gerais, the research incorporates 29 interviews with local value chain actors, 14 supplementary interviews with institutional stakeholders, and secondary data analysis. The findings reveal a fragmented and predominantly informal value chain at the local level, faced with challenges such as physically intensive work, unreliable demand, power imbalances, low-profit margins, and limited institutional support. This research proposes strategies to foster collaboration, equity, transparency, and sustainable development of Baru's value chain and contributes to a deeper understanding of this NTFP.}, language = {en} } @misc{Yarram2025, type = {Master Thesis}, author = {Yarram, Sunnyvijay}, title = {Investigation of Anaerobic Digestion of Selected Bioplastics in Pilot-Scale Biodigesters}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-21673}, school = {Hochschule Rhein-Waal}, pages = {102}, year = {2025}, abstract = {Concerns have been raised about the end-of-life management of bioplastics as their demand increasing as a sustainable alternative to conventional plastics. The fate of bioplastic waste, especially packaging waste, remains largely unexplored in existing waste management systems. Anaerobic digestion (AD) is considered as a viable end-of-life option for bioplastics, however, current research has been primarily limited to lab-scale studies. This study investigated the anaerobic digestion of film samples made from Bioplast 106, PBAT, PLA and Ecovio (PLA/PBAT blend) under mesophilic and thermophilic conditions in pilot-scale biodigesters. The results of 90-day thermophilic AD demonstrated that PLA and Ecovio exhibited significant biodegradation of 36\% and 50\% by dry mass loss, respectively, while Bioplast 106 exhibited moderate biodegradation of 22.22\%. The collective methane yield from these three bioplastics was 322.86 mL CH4/g VS, indicating their potential for biogas production. SEM and FT-IR analyses confirmed structural degradation of Bioplast 106, PLA, and Ecovio, while no degradation was observed for PBAT. PBAT showed high resistance to AD in pure and blended form (Bioplast 106, Ecovio). Bioplast 106 exhibited diverse degradation patterns, influenced by feedstock type, digester temperature, and processing conditions. This study might serves as valuable reference for assessing the anaerobic biodegradability of Bioplast 106 in pilot-scale biodigesters. This study further highlights the necessity of optimization of pilot-scale AD conditions to enhance the anaerobic biodegradability of slow-degrading bioplastics.}, language = {en} } @masterthesis{DosSantos2025, type = {Bachelor Thesis}, author = {Dos Santos, Leonardo Henrique}, title = {The effects of cannabinoids CBD and WIN 55 212-2 against oxidative stress in BR1 Astrocytes from a proteomic viewpoint}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-21665}, school = {Hochschule Rhein-Waal}, pages = {92}, year = {2025}, abstract = {Oxidative stress is a common hallmark observed in neurodegenerative diseases, acting either as a triggering factor or as a consequence of the neurodegenerative process. Astrocytes play a crucial role in mediating oxidative stress caused by physiological processes, such as the byproducts of mitochondrial function during cellular respiration. Given the critical role of oxidative stress in the progression of many neurodegenerative diseases, identifying molecules capable of modulating this response and mitigating oxidative damage is of considerable interest. Cannabinoids such as cannabidiol (CBD) and WIN 55.212-2, known for their capability of influencing the endocannabinoid system through their interaction with cannabinoid receptors (namely, CB1R and CB2R), and therefore the Central Nervous System, are promising candidates for such modulation. This work aimed to explore, through proteomics, the potential effect that the mentioned cannabinoids might have against oxidative stress induced by hydrogen peroxide in astrocytes, possibly mitigating some of the oxidative damage.}, language = {en} } @misc{OPUS4-2165, title = {08/2025 Ordnung {\"u}ber die Auslaufplanung f{\"u}r den Bachelorstudiengang „Nachhaltiger Tourismus" der Fakult{\"a}t Gesellschaft \& {\"O}konomie an der Hochschule Rhein-Waal vom 04.02.2025}, volume = {2025}, number = {8}, organization = {Hochschule Rhein-Waal}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-21657}, pages = {5}, language = {de} } @misc{OPUS4-2164, title = {07/2025 Dritte {\"A}nderungssatzung zur Pr{\"u}fungsordnung f{\"u}r den Masterstudiengang Economics and Finance der Fakult{\"a}t Gesellschaft und {\"O}konomie vom 14.01.2025}, volume = {2025}, number = {07}, organization = {Hochschule Rhein-Waal}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-21648}, pages = {5}, language = {de} }
