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. Previous research has mostly focused on short-term organizational outcomes, and there is limited evidence about the factors that enhance job satisfaction and ensure long-term performance of an organization. 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. The study suggests that when organizations actively follow and implement these factors, it is more likely to increase employee satisfaction and satisfied employees improve productivity, achieve organizational goals, and increase a higher level of dedication, which ensures organizational long-term performance.}, language = {en} } @masterthesis{Bhalla2025, type = {Bachelor Thesis}, author = {Bhalla, Kushagra}, title = {Strategic Obsolescence Management: Developing a Process-Oriented and Financially Viable Concept}, school = {Hochschule Rhein-Waal}, year = {2025}, abstract = {Industrial machinery is designed for long operating periods, but many electronic and mechatronic components used in these systems are discontinued after a short product lifecycle. 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. Overall, the proposed structure provides a clear basis for more consistent and reliable lifecycle handling across the organisation.}, language = {en} } @misc{Friesen2025, type = {Master Thesis}, author = {Friesen, Emilie}, title = {Optimierung des administrativen und pflegerischen Aufnahmeprozesses in einer Akutklinik - Eine praxisorientierte Prozessanalyse}, school = {Hochschule Rhein-Waal}, year = {2025}, abstract = {Das deutsche Gesundheitswesen steht vor einer Vielzahl von Herausforderungen.

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. All in all, to strengthen the relationship between urban consumers and local producers cultural and structural changes are required, in which consumers, producers and the city itself share common responsibility.}, language = {en} } @masterthesis{JagjitSingh2025, type = {Bachelor Thesis}, author = {Jagjit Singh, Humjeet Singh Gill}, title = {The effect of shearing in a twin-screw extruder on the mechanical properties of biopolymers (PLA+PBAT) using varied screw designs}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-22950}, school = {Hochschule Rhein-Waal}, pages = {75}, year = {2025}, abstract = {The primary aim of this research project was to determine the effects of shearing on the structure of a blend of biopolymers (PLA+PBAT) through tailored screw designs in a twin-screw extruder. To achieve this, 3 different twin intermeshing co-rotating screw designs of an extruder were used. 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. The compounded pellets produced from the 3 screw designs were then used in a Blown Film machine. Furthermore, tensile test was conducted on the resulting samples. The shear strength and strain of the films were calculated. Tear test of the films were additionally carried out to validate the findings. Fourier Transform Infrared (FTIR) test was conducted to study the functional groups, identifying the chemical interactions and phase compatibility of the of PLA\&PBAT blend. The results showed that the screw with 3 kneading blocks (HS) and 2 kneading blocks (MS) exhibited almost similar ultimate strength and ultimate strain. The screw design with only conveying elements had lower ultimate strength and strain. The kneading blocks played a role on the mixing and shearing of the biopolymer structure in the blend.}, language = {en} } @masterthesis{Ganev2025, type = {Bachelor Thesis}, author = {Ganev, Ivan}, title = {Design and Implementation of a Virtual Gearbox}, school = {Hochschule Rhein-Waal}, year = {2025}, abstract = {This thesis represents the design and implementation of a virtual gearbox functionality as a system with an end goal to be used on the Electric Gokart platform.

To advance the state of the art, research should explore new combinations of chemical and practical components to discover syntheses with novel emergent properties. However, given the vast amount of information available, it is challenging to systematically narrow the search to an effective comparison of a few select candidates. This work proposes a selection and evaluation methodology for building a comparative scope to decide on a set of hydrogel recipe components. Recipe design needs are determined using an existing bibliometric analysis of a hydrogel subfield, and available options are sourced from literature reviews, then assessed based on properties discussed in the literature. Candidates for the crosslinking initiation mechanism, the monomer system, and the crosslinking control method are evaluated separately and sequentially. Recipe permutations are possible as multiple choices are scored. The resultant recipe is a photoinitiated (LAP; irradiated at 380.5nm), thiol-ene (TMPMP-Maleimide), light-patterned (maskless PWM-DLP) hydrogel that swells and bends in response to water due to osmolyte (D-Sorbitol) diffusion.
