This bachelor thesis investigates the impact of LGWs on indoor environmental quality, employees' well-being, and performance in the offices of the Facility Management Department of Hochschule Rhein-Waal (HSRW) - Kleve campus. A hybrid methodology is adopted, combining sensor measurements of physical parameters and a self-developed questionnaire assessing perceived LGW impact. The sensors are set up in four offices, three of which featured LGWs, while the questionnaire is distributed online to workers before and after the LGW installation. Eight workers participated in the study, of which 62.5 \% were female, and 37.5 \% were male, with age range between 25 and above 45 years old. The results indicate a positive overall impact of LGWs on office environmental quality and employee well-being. The CO2 concentration was reduced on average by 30 ppm, whereas the relative humidity was increased, on average, by approximately 6 \%. Hence, the LGWs enhanced slightly the air quality in the offices. Moreover, the target group claimed that their motivation level, on average, was raised by 15\% after exposure to the LGWs. Hence, half of them agreed that the LGWs impacted their performance positively. However, challenges emerged concerning LGW technical design and employee engagement with the research. Despite obstacles, the study suggests potential for future improvements in methodology and technical aspects, offering promising project ideas for further research. Furthermore, the overall positive impact of LGW in this study has proven that integrating such systems into work environment can boost the motivation level of the workers and improve the environmental quality in workspaces.}, language = {en} } @masterthesis{Tebest, type = {Bachelor Thesis}, author = {Tebest, Marie}, title = {Schneller Nachweis der Methicillin-Resistenz bei Staphylokokken-Isolaten Vergleich verschiedener Methoden}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-19727}, school = {Hochschule Rhein-Waal}, pages = {74}, abstract = {Methicillin Resistente Staphylococcus aureus (MRSA) geh{\"o}ren zu gef{\"u}rchteten Erregern eines bunten Bildes von Infektionen, die bis zu einer Sepsis reichen k{\"o}nnen. Eines der gr{\"o}ßten Probleme von MRSA ist die hohe Pathogenit{\"a}t und die Entwicklung von zus{\"a}tzlichen Resistenzen gegen{\"u}ber weiteren Antibiotikaklassen. Die schnelle Identifizierung von MRSA und das Anlegen eines Antibiogramms ist daher entscheidend f{\"u}r eine fr{\"u}he Therapie-Empfehlung und damit verbunden eine optimale Behandlung des Patienten. Aufgrund dessen wird in der vorliegenden Arbeit nach weiteren M{\"o}glichkeiten in der mikrobiologischen Diagnostik gesucht, um die Zeitspanne zwischen dem ersten Laborverdacht auf eine MRSA-Infektion und der spezifischen Antibiotikatherapie nach der Erregeridentifizierung zu reduzieren. Dazu wurden zwei verschiedene Methoden (MRSA-polymerase chain reaction (PCR) und Penicillin-Bindeprotein 2a (PBP2a)-Schnelltest), bez{\"u}glich ihrer Leistungsdaten mitdem Goldstandard zum Nachweis der Methicillin-Resistenz (VITEK-2 und Cefoxitin� Best{\"a}tigungstest) verglichen. Die klinischen Isolate f{\"u}r die experimentelle Durchf{\"u}hrung stammen aus Blutkulturflaschen und Abstrichen von intraoperativen Wunden. Insgesamt wurden 74 Isolate retrospektiv getestet, darunter 26 (35\%) MRSA� Isolate, 24 (32,5\%) Methicillin-sensibler Staphylococcus aureus-St{\"a}mme und 24 (32,5\%) Koagulase-negative Staphylokokken (KnS). In der MRSA-PCR kam es zu 15 (20\%) fraglichen Ergebnissen, weshalb die Methode f{\"u}r eine zuverl{\"a}ssige Routinediagnostik nicht geeignet erschien. Nach Ausschluss der fraglichen Ergebnisse hatte die PCR einen positiven pr{\"a}diktiven Wert (PPW) von lediglich 65,7\%. Die Sensitivit{\"a}t lag bei 92,9\%, die Spezifit{\"a}t bei 93,5\% und der negative pr{\"a}diktive Wert (NPW) bei 99,0\%. Der Schnelltest besaß eine Spezifit{\"a}t und einen PPW von 100\%, eine Sensitivit{\"a}t von 97,3\% und einen NPW von 99,6\%. Des Weiteren ergaben sich zus{\"a}tzliche Vorteile bei der Verwendung des Schnelltestes durch die k{\"u}rzere Laufzeit, den geringeren Kostenaufwand und die Einfachheit der Durchf{\"u}hrung. Der ermittelte Zeitgewinn durch PCR oder Schnelltest betrug im Vergleich zum VITEK-2 zwischen 15 und 23,8 Stunden, was f{\"u}r die betroffenen Patienten von erheblichen klinischem Vorteil war. Zusammenfassend hatte der PBP2a-Schnelltest sowohl f{\"u}r S. aureus- als f{\"u}r KnS-Isolate bessere Leistungsdaten als die verwendete MRSA-PCR und wurde deshalb in die Routinediagnostik des Labors eingef{\"u}hrt.}, language = {de} } @masterthesis{Haas, type = {Bachelor Thesis}, author = {Haas, Alexandra}, title = {Empirische Untersuchung der {\"A}tiologie von subklinischem Wahn in einer gesunden Stichprobe: Der Einfluss von Kindheitstrauma, Theory of Mind F{\"a}higkeiten und einem niedrigen Selbstwert}, school = {Hochschule Rhein-Waal}, abstract = {Hintergrund: Psychotisches Erleben, wie z.B.

Der aktuelle Forschungsstand geht davon aus, dass Wahn dimensional in der Allgemeinbev{\"o}lkerung ausgepr{\"a}gt ist und eine hierarchische Struktur aufweist, die von subklinischem Wahn bis hin zu psychotischen St{\"o}rungen reicht. Risikofaktoren wie Kindheitstrauma, Theory of Mind (ToM) Defizite und ein geringer Selbstwert erh{\"o}hen die Wahrscheinlichkeit f{\"u}r wahnhaftes Erleben. Um ein besseres Verst{\"a}ndnis der {\"A}tiologie von subklinischem Wahn zu bekommen, ist es wichtig, die Effekte dieser Risikofaktoren in gesunden Stichproben zu untersuchen. Methodik: Die vorliegende Studie untersuchte 100 gesunde Proband*innen der deutschen Allgemeinbev{\"o}lkerung in Bezug auf subklinisches Wahnerleben. Mittels Frageb{\"o}gen und computergest{\"u}tzter neuropsychologischer Tests wurde subklinischer Wahn, Kindheitstrauma, ToM-F{\"a}higkeiten und der Selbstwert der Proband*innen erfasst. Mehrere statistische Verfahren, wie eine Hauptkomponentenanalyse sowie Korrelations-, Regressions- und Mediationsanalysen wurden genutzt, um die Zusammenh{\"a}nge, Varianzaufkl{\"a}rungen und die pr{\"a}diktive G{\"u}te der genannten Variablen in Bezug auf subklinischen Wahn zu untersuchen. Ergebnisse: Subklinischer Wahn liegt in einem geringen Ausmaß in der Stichprobe vor. Ein signifikant positiver Zusammenhang zwischen subklinischem Wahn und Kindheitstrauma wurde gefunden. Zudem konnten signifikant negative Zusammenh{\"a}nge zwischen subklinischem Wahn und ToM-F{\"a}higkeiten sowie mit Selbstwert gefunden werden. Die Ergebnisse der Regressionsanalyse unterstreichen die pr{\"a}diktive G{\"u}te von Kindheitstrauma und geringem Selbstwert f{\"u}r subklinischen Wahn. Dar{\"u}ber hinaus zeigt die parallele Mediationsanalyse, dass Selbstwert ein signifikanter Mediator f{\"u}r die Beziehung zwischen Kindheitstrauma und subklinischem Wahn ist.

It presents a formidable challenge exacerbated by urbanization, shifting consumption patterns and global disruptions like the COVID-19 pandemic. In response, alternative food sources such as edible insects are gaining traction as sustainable solutions. Edible insects offer comparable nutrition to traditional protein sources while requiring minimal resources for farming. However, unsustainable harvesting practices endanger wild insect populations. To counter this, insect farming emerges as a promising strategy, leveraging efficient conversion rates and organic waste utilization. This paper explores how edible insects can integrate into circular food economies, converting organic waste into valuable resources, bolstering food and feed security, and mitigating waste. Specifically, it examines the potential of insects like black soldier fly larvae, yellow mealworms, houseflies, and house crickets in SSA for waste management and sustainable nutrition. The discussion encompasses insect abundance, waste utilization, economic cycles, and environmental benefits. Furthermore, it explores the quality and quantity of available urban organic waste streams, waste-to-insect combinations, and the socioeconomic implications of insect farming, including gender dynamics and consumer acceptance. The review highlights the need for regulatory frameworks to govern the edible insect industry in SSA and emphasizes the potential of insect farming to contribute to food security, environmental conservation, and economic development in the region.}, language = {en} } @masterthesis{Decher, type = {Bachelor Thesis}, author = {Decher, Isabelle}, title = {Analysing Marketing Strategies of Agroforestry-Grown Walnuts: Lessons for the Lower Rhine Region}, school = {Hochschule Rhein-Waal}, abstract = {Agroforestry (AFS) could help fight climate change by sequestering carbon (Nair et al., 2021). However, few markets accurately reflect the value of agroforestry products, posing a barrier to farmers implementing AFS (Litschel et al., 2023). In addition, while AFS could i.e. help the Lower Rhine Region reduce nitrate pollution, there is little research on AFS in this region. This thesis aims to reduce these barriers to AFS in the Lower Rhine Region by developing a marketing strategy for one promising agroforestry product: walnuts (Juglans regia). To do this, consumer prices of 62 walnut products from 15 stores in the Kleve area were collected over 46 days to gain an insight into the local market. Secondly, expert interviews were conducted with three German walnut producers to assess their marketing strategies. The SIVA framework (Solution, Information, Value, Access) by Dev and Schultz (2005), was used to analyse the transcripts. Then, the results were adapted to the context of the Lower Rhine Region and agroforestry to provide marketing guidelines for producers of AFS-grown walnuts in the Lower Rhine Region. Results show that not only could new walnut producers successfully compete with imported walnuts in the Lower Rhine Region, but that agroforestry could also be a significant asset to their marketing strategy.}, language = {en} } @misc{OPUS4-1954, title = {06/2024 Erste {\"A}nderungssatzung zur Ordnung zur Feststellung der studiengangsbezogenen k{\"u}nstlerisch-gestalterischen Eignung f{\"u}r den Masterstudiengang Design and Interaction der Fakult{\"a}t Kommunikation und Umwelt vom 20.03.2024}, volume = {2024}, number = {06}, organization = {Hochschule Rhein-Waal}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-19540}, pages = {3}, language = {de} } @misc{OPUS4-1953, title = {05/2024 Vierte {\"A}nderungssatzung zur Rahmenpr{\"u}fungsordnung f{\"u}r die Bachelor- und Masterstudieng{\"a}nge an der Hochschule Rhein-Waal vom 02.04.2024}, volume = {2024}, number = {05}, organization = {Hochschule Rhein-Waal}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-19530}, pages = {4}, language = {de} } @misc{OPUS4-1952, title = {04/2024 Dritte {\"A}nderungssatzung zur Pr{\"u}fungsordnung f{\"u}r den Bachelorstudiengang Mechanical Engineering B.Sc. der Fakult{\"a}t Technologie und Bionik an der Hochschule Rhein-Waal vom 09.04.2024}, volume = {2024}, number = {04}, organization = {Hochschule Rhein-Waal}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-19523}, pages = {5}, language = {de} } @misc{Hoetger, type = {Master Thesis}, author = {H{\"o}tger, Marvin}, title = {Evaluation of the potential of a silphie supply chain for fiber production and CO2 binding in East-Westphalia Lip}, school = {Hochschule Rhein-Waal}, abstract = {The present thesis focuses on the potential of the alternative fiber plant Silphie (Silphium perfoliatum) in East Westphalia-Lippe. To assess its potential, three expert interviews were conducted in the beginning with the key stakeholders of a Silphie supply chain. These stakeholders included the fiber producer OutNature, the seed distributor Donau-Silphie, and the CO2 certification company Positerra. Through these interviews, the necessary conditions for establishing a Silphie cultivation region for paper production were determined. Subsequently, the attitudes of local farmers towards cultivation and further use of the plant were surveyed. Additionally, the potential for CO2 sequestration of Silphie was assessed and compared with the opinions of the farmers. The results from the interviews and the survey were used to identify patterns using explorative data analysis and descriptive statistics methods, enabling the prioritization of potential farmers in the future. The evaluation of the methods revealed an interest in cultivation and fiber production under certain conditions. The most important prerequisites include profitability, secured take-off agreements, and the suitability of using the plant as fodder. Consequently, farmers with a larger farm size who cultivate silage maize for biogas production are most willing to grow Silphie. By geographically mapping potential Silphie areas, two preferred catchment areas were identified where the chance for a cultivation region is favorable due to existing infrastructure and farmer interest. Furthermore, a comparison of the required environmental conditions with those present in OWL was conducted and mostly deemed accurate. Based on these findings and the development of further utilization possibilities for Silphie, this thesis serves as a motivation for additional studies aimed at increasing the potential of Silphie in OWL.}, language = {en} } @masterthesis{Ina, type = {Bachelor Thesis}, author = {Ina, Hickmann}, title = {Potential of Social media marketing for farm shops}, school = {Hochschule Rhein-Waal}, abstract = {n the age of digital networking, social media has developed into a central tool that is reshaping the communication landscape.

However, it is associated with a lot of new challenges for e-commerce businesses, particularly in understanding and managing the customer behavior patterns with the rising online product returns. Since the accessibility of online shopping has risen, assessing the critical factors related to product return and prediction has become a really challenging task for e-commerce vendors. This study also aims to segment the customers based on customer behavior prediction into two categories, i.e., high return risk and low return risk customers, and further develop strategies to reduce the online returns. This study is rather structured into four integral parts, where each part provides the comprehensive analysis. The first aspect involves analyzing and identifying the customer behavior patterns leading to product returns. The second aspect predicts the online product return based on selected features and the third is to segment the customers based on online product return prediction and categorize them into high return risk, and low return risk customers. The final step involves development of strategies to reduce the product return based on the intense analysis conducted. To achieve this meaningful research outcome, data analysis is conducted to understand the customer behavior patterns, and a Random Forest feature selector is used to identify the customer behavior patterns that lead to product return. Based on the identified features, classification models were applied to classify and predict whether the customer is going to return product or not. Furthermore, in these seven classification models such as Logistic Regression, Ada Boost, Decision Tree, Naive Bayes, XG Boost, K-Nearest Neighbors, and Random Forest were implemented and used to compare the performance of the classification models to find out the best performing model. Lastly, the segmentation of customers is carried out based on the online product prediction using Logistic regression with classification threshold method into high return risk and low return risk customer categories. The results obtained help in understanding the customer behavior and reduce the online product return by developing the strategies.

Thus, green infrastructures like golf courses have emerged as a potential contributor to biodiversity conservation. Therefore, the research focuses on a golf course in Krefeld, Germany, by examining its role in supporting, conserving, and improving local biodiversity. The objectives include assessing the biotopes and habitats provided by the golf course, investigating the potential of an ecosystem analysis to enhance overall biodiversity, and evaluating the golf course's effectiveness in conserving local species of conservation concern. Through landscape analysis, significant differences between the golf course and surrounding areas were observed. The golf course was ascertained to exhibit a significantly higher biotope value compared to other land use systems except natural ones. Woody biotopes, including forests and tree groups, demonstrated the highest on-course biotope values, while short-kept grass, roughs, ponds, and non-native woody structures were less valuable. Theoretical enrichments of meadow-, pond-, and non-native biotopes as well as their relative size indicated potential for improving biotope value to support biodiversity. Combined enrichments were indicated to be the most effective. Despite the current presence of only a few habitat types, the golf course was found to support local fauna and flora species of conservation concern. Adaptations, such as creating meadow-, riparian-, copse-, and forest habitats, showed promise to further improve biodiversity. The study identified landscape context and prior land use as crucial factors influencing golf course's value. Overall, the golf course demonstrated potential in providing valuable biotopes, and habitats and supporting local and regional species of conservation concern. The findings suggest that golf courses, particularly in urban and suburban areas, can serve as effective contributors to biodiversity conservation by enhancing landscape connectivity and providing essential habitats. Enrichment strategies, coupled with a focus on specific habitat types, offer practical avenues for improving the conservation status of both local and regional flora and fauna species on golf courses.

Moreover, UA largely mitigates the negative impacts associated with conventional agriculture systems such as soil degradation, high resource usage, crop sensitivity towards climate change, and high fertilizer usage. UA is often complimented for its significant potential for producing higher yield nevertheless, for extensive use of UA, an in-depth understand- ing of its environmental impacts is required. For any UA methodology, environmental performance acts as a promising factor in promoting agriculture sustainability. This study performs critical analyses of available literature on UA techniques using Life Cycle Assessment (LCA). LCA provides a comprehensive understanding of UA's environmental footprint across different stages of its life cycle. LCA facilitates the quantification of eco- logical impacts associated with various UA approaches, including vertical farming, roof- top farming, hydroponics, aquaponics, and aeroponics. This study utilizes a systematic review methodology, incorporating the PRISMA model, to conduct a comprehensive data collection process aimed at identifying the LCA of diverse UA methods and their associated impacts. The review addresses the following questions: How does LCA help in quantifying the environmental impacts of UA? What is the environmental performance of different UA techniques? The findings demonstrated that nearly every form of UA exhibited a notable advantage in yield, and efficiency in water usage and land usage. Specifically, aeroponics stands out for its superior performance in yield and water usage efficiency, albeit with elevated energy demands. Hydroponics and aquaponics showcase advantages in reduced water usage and fertilizer requirements. Vertical farms, due to their structural and Controlled Environment (CE) prerequisites, present as energy-intensive systems with higher Greenhouse Gas (GHG) emissions. In contrast, rooftop farms, making use of under-utilised urban spaces, emerge as a balanced system with moderate energy consumption and GHG emissions. The environmental impact of UA techniques varies based on factors such as structure, operational components, crop selection, and the integration of innovative technologies, resulting in diverse outcomes when compared to conventional soil-based farms.

The effects of diminishing green spaces, increasing sealed spaces, and higher summer temperatures are particularly noticeable in built-up and urban areas. The constant use of land and development means that insect habitats, which are essential to a functioning ecosystem, are being lost. But this development is not only problematic for insects: increased sealing also increases the potential risk of the heat island effect, which poses a threat to human health. One possible solution for providing habitat and food for insects in urban areas could be green fa{\c{c}}ade systems. These could partially restore ecosystem services lost to development and have a positive effect on ambient temperature through shading of the building and evaporation from the plants. In order to measure this effect of fa{\c{c}}ade greening on the environment, in particular on insect diversity and insect population, this work measured the number of insects using two different counting methods over several days on two external fa{\c{c}}ades, one with fa{\c{c}}ade greening and one without.

The observed methodology was obtained by systematically reviewing and comparing other similar scientific studies to determine the challenges and risks associated with using pig grafts (islet, pancreas, beta cells) for the treatment of type 1 diabetes (T1D), the optimal pig age for extracting graft for treatment of diabetes, differences between human and pig insulin, and the clinical trials and adoption pig insulin and graft therapies for type 1 diabetes treatment. Xenotransplantation of pig grafts has successfully restored normoglycemia in a Type 1 diabetes patient for about 9.5 years, thus potentially being an alternative therapy to human islet allotransplantation. However, the clinical adoption of using pig grafts for diabetes treatment is hindered by the unavailability of T1D volunteers to be used for clinical trials because of risks like zoonosis, loss of body weight, immunosuppression, and death of the transplanted pig implant. Xenotransplantation of pig grafts to T1D can be clinically accepted through advanced practices like Genetic modifications of the pig, encapsulating the pig grafts before transplantation, and co-transplantation of the pig grafts with Mesenchymal Stem Cell (MSCs) and/or Sertoli cells (SCs).

This disease mainly infects herbivores, but many mammals can be hosts as well, including humans. Multiple cases in history are known, in which human infection resulted either from digestion or handling of contaminated animal products, from industry accidents or bioterrorism attacks. The endospores of B. anthracis are persistent to harsh environmental conditions and can survive in soil for decades, before heavy rains or grazing animals can reemerge the spores again. In appropriate medium, like blood, the spores germinate again to the vegetative cell form. B. anthracis belongs to the "Bacillus cereus group" which shares high genetic similarity, with cases where the virulence plasmids of B. anthracis, which are responsible for the toxin and capsule production, are even shared with other members of this group. Species-specific testing therefore often poses a challenge, because sophisticated equipment and financial investments are needed for a correct diagnosis. Because of appearing new infection cases, a species-specific, rapid and inexpensive method for the detection of B. anthracis is needed. Apart from the gold standard of detection of B. anthracis via PCR, receptor-binding protein (RBP) based detection methods are in research for a few years. Bacteriophages (phages) represent the most prevalent biological entities on earth and are viruses targeting bacterial cells. Brown and Cherry isolated a phage named gamma (γ), demonstrating high efficiency in infecting encapsulated bacilli. Notably, the γ phage exhibited sensitivity across nearly all variants of B. anthracis, while members of the B. cereus sensu lato group displayed resistance. The specificity of phages is attributed to their RBPs, which recognize distinct structures on the host cell, inducing the initial step of phage infection. One of these RBPs specific for B. anthracis is BA4079Δ1-127. This work aims to produce two recombinant fusion proteins, with two different cellulose-binding domains (CBDs) which were internally linked to the fluorescent reporter protein superfolder green fluorescent protein (sfGFP) and coupled to BA4079Δ1-127. The protein tools would enable binding to B. anthracis and at the same time would allow sequestration to cellulose materials. Because of the fluorescence protein, the sample can be observed by fluorescence microscopy and cells or cellulose bound to the fusion proteins would exhibit green fluorescence. This experimental approach could lead to a new low-cost enrichment tool for B. anthracis cells using the fusions proteins containing CBDs, RBPs and fluorescence proteins. The fusion proteins were tested with various cultures of B. anthracis cells, grown under different conditions, as well as different cellulose materials including cotton wool in a syringe, cotton wool fibers, cellulose filters and microcrystalline cellulose. Binding tests showed, that the fusion proteins were not able to connect B. anthracis cells with diverse cellulose materials in a way that cells could be enriched from media.

The findings reveal a consistent and positive correlation between the neurotrim method and enhanced balance performance in individuals with CAI. Height consistently emerged as a factor influencing balance across assessments, while the relationships of age, weight, and BMI with balance outcomes displayed fluctuations over assessment phases. The outcomes of the study underscore the potential of the neurotrim method as a promising rehabilitation intervention for individuals with CAI, emphasizing the need for tailored strategies to enhance balance in this population.}, language = {en} } @masterthesis{Huelshoff, type = {Bachelor Thesis}, author = {H{\"u}lshoff, Kristina}, title = {Visualisierung klimafreundlicher Baumaßnahmen am Beispiel der Stadt Xanten}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-18847}, school = {Hochschule Rhein-Waal}, pages = {60}, abstract = {Due to anthropogenic climate change, cities need to be restructured.

In this work, Pepper was connected to GPT-Engine to act as a voice assistant robot. With the help of GPT-Engine Pepper can answer questions about the University and its study programmes. The enhancement involves a client-server architecture, where the client-side application enables students to interact with Pepper via speech, and the server-side, equipped with AI functionalities, processes these interactions and generates appropriate responses. This setup significantly augments Pepper's capabilities, allowing for more accurate and efficient information delivery. An experiment was conducted with nine student participants of Hochschule-Rhein Waal, where they asked questions about the University and study Programmes to inform themselves about the University and Study Programmes. During the interaction, they evaluated the robot's clarity of communication, accuracy of responses, and overall user experience. The findings indicate that while the AI enhancements generally improved Pepper's ability to communicate and provide information, areas such as voice recognition and response accuracy require further improvement.

Because of climate change, Europe is expected to see an even higher number of floods in the coming decade. As floods cannot be prevented, understanding the pattern and causes and being able to forecast could significantly reduce the losses during the flood. In July 2021, Germany faced a catastrophic flood, taking more than 180 people's lives and causing around 40 billion euros of economic loss. To study the flooded region and the region at high risk, the Flood event 2021 has been visualized in this research. The Flood map has been created using a sentinel-1 image. In the visualization, floods in the Rhine River and Arh River can be seen, and the change in the pattern of flood from 12th July to 16th July has also been observed. Different models exist that try to predict floods and warn as early as possible. Since Machine learning is popular nowadays in every sector, ML models have been implemented in this study to forecast the flood. The SARIMA, Random Forest, and LSTM have been implemented using historical data to predict the flood. The Random Forest model performed better than the remaining two models. The Isolation Forest model has also been implemented to classify the data into Flood and No Flood.

The thesis begins by outlining the limitations of traditional, static methods of form rendering, highlighting the implications for development time and error frequency. It identifies the fragmentation in the existing API-driven architectures as a critical issue affecting system reliability and user experience. Against this backdrop, the work proposes a unified, API-driven framework to dynamically render forms for many user actions, such as data input and transactions. The research takes a deep dive into existing systems—particularly Informatica's Product Information Management (PIM) software and the new software in development Article Workbench to identify user experience issues, inefficiencies, and the complexities involved. Through this examination, it offers a targeted solution to integrate various components of form management, like building, parsing, validation, and rendering, into a cohesive system. The thesis aims to contribute to software development and user experience design substantially, by targeting improved development efficiency, reduced errors, and enhanced system reliability.

Recently, these wetlands are discussed about for their Climate Change mitigation potential by re-wetting efforts. Since most studies on the topic of potential greenhouse gas (GHG) emission reduction in Germany focus on large areas in the North and South of Germany, this study observes a smaller example area of organic soil in Kleve, North-Rhine Westphalia. It is analyzed in terms of suitability for paludiculture as well as for potential savings of GHG and a reduction of the Global Warming Potential (GWP). The study introduces a ranking system that allows an easy estimation of the suitability of fields, based on criteria that assign points from 1 to 4 per criteria. The total for each field is compared with one another. Emission values are based on the GEST-approach, developed by moor scientists in Greifswald, Germany. This study compares current field emissions in Kleve and compares them to theoretical agricultural cultivation scenarios that are simulated and projected onto said fields. The scenarios include the cultivation of Phragmites australis, a grazing system with Bulbalus arnee and the neglection of agriculture supplemented with photovoltaic power harvesting. The research highlights that maintaining high water levels is crucial for significant greenhouse gas emission savings. Water levels of around the soil surface level are assumed to have the highest potential for such savings. Phragmites australis cultivation and the grazing scenario demonstrate the highest potential for savings, reaching up to 2118.56 t CO2-equivalent per hectare annually.

We furthermore de-termined the bacterial community composition by high-resolution melt analysis and 16S ri-bosomal DNA RNA (16S rRNA) gene sequencing. Depending on the initial intrinsic prevalence of intI1 in the respective ex situ biofilm, Benzalkonium Chloride, Alkylbenzene Sulfonate and Cocamidopropyl Betaine increased intI1 prevalence by an average of up to six fold. For surfac-tants, such as Fatty Alcohol Ethoxylate and the biosurfactants Sophorolipide and Rhamnoli-pide, the mean increase in intI1 prevalence did not exceed two fold. Across all surfactants the increase of intI1 was accompanied by a shift in bacterial community composition.

The main results include the decisions taken for the plant's design, the efficiency and performance of the Agri-PV system, the economic results obtained through simulations in PV*SOL software, and the use of plans developed in AutoCAD. The objective of the report is the correct implementation of the Agri-PV system in both the test area and the potential area.
