TY - THES A1 - Batson, Adiel T1 - INVESTIGATING SOIL BIOLOGICAL ACTIVITY IN VARIABLE AGRICULTURAL SAMPLE SITES USING BAIT LAMINA METHODOLOGY N2 - This research investigates the relationship between feeding activity and soil characteristics using Bait Lamina Methodology at six agricultural sample sites in western Germany. The ability to incorporate citizen science for data collection and evaluation is assessed and the quality of that data is compared using analysis of variance between group types. It was found that fertilization is strongly correlated with feeding activity (0.877). Positive correlations between temperature, soil moisture and soil organic matter content were also observed, although with varying degrees of influence. Mean feeding activities among different evaluating groups of students, staff, pupils, scout members and farming cooperative members (Solawi) did not deviate significantly from each other (p= 0.66 among students, Solawi and staff members, and p=0.52 among students, pupils and scout members, alpha= 0.05) . Data processing however for non staff and student groups was more arduous as more tallying mistakes were made than formerly mentioned groups. Results suggest that the bait lamina methodology is suited for citizen science, although data quality can easily be improved by digitizing evaluation handouts, with automation/formulas embedded for tallying.

This transition necessitates an improved un-derstanding of how managerial actions influence the dynamics within these teams, to optimally align them for success. Despite the substantial research about leader effec-tiveness and team effectiveness based on organizational performance indicators, it is rather infrequent that the direct influence of leader behavior on teams is explored. This thesis aims to address this gap by answering how leader behaviors impact team pro-cesses in the context of German medium to large-scale IT-enterprises. Using a quanti-tative cross-sectional methodology, individuals working in team-based structures under direct supervision were surveyed. Analyzing data from 94 respondents via hierarchical linear regression analysis, several significant relationships were identified. In general, leader behavior has a strong positive impact on team processes. Furthermore, task-oriented leaders have the greatest positive influence on action processes, while relation-oriented leaders have the greatest positive influence on interpersonal processes. Change-oriented leaders also significantly influence action processes and interpersonal processes, albeit less strongly than their counterparts. These results provide implications for team management practices, emphasizing the importance of leader behavior for aligning team processes in the direction of success.

Hierfür wurden die Daten von 210 Teilnehmenden mittels einer quantitativen Online-Befragung untersucht. Dazu wurde die Kurzskala UGK-V der SEU-3 mit 21 Items genutzt. Diese beinhaltet sieben Inhaltskalen und misst die Konstrukte Einstellung, Verhaltensintention und selbstberichtetes Verhalten. Zudem wurden drei Items zur Erfassung von Bewusstheit von Handlungskonsequenzen genutzt. Es konnten signifikante Zusammenhänge zwischen den umweltrelevanten Konstrukten gefunden werden. Am stärksten korrelierte die Einstellung mit der Verhaltensbereitschaft. Die postulierten Hypothesen konnten bestätigt, müssen aber durch niedrige Reliabilität des selbstberichteten Verhaltens eingeschränkt betrachtet werden. Die Bewusstheit über Handlungskonsequenzen konnte mit allen Unterskalen und der Gesamtskala in Verbindung gebracht werden. Am höchsten korrelierte diese mit dem Umweltbewusstsein. Die angenommene Korrelation (H4) stellte den kleinsten Zusammenhang dar, was darauf hindeutet, dass Bewusstheit für Handlungskonsequenzen eher mit der Einstellung als mit Verhalten in Verbindung gebracht werden kann. Die Kausalität kann nicht festgestellt werden, so ist eine Wechselwirkung nicht auszuschließen. Uneinheitliche Definitionen der Konstrukte erschweren neben einer unzureichend repräsentativen Stichprobe eine Verallgemeinerung auf die Bevölkerung. Die Ergebnisse können mit den Werten der Originalquellen verglichen werden und zeigen valide Erhebungsinstrumente. Die Studie hebt die Diskussion um den Effekt einer Verhaltensmodifikation zur Lösung ökologischer Probleme hervor. N2 - The aim of this Bachelor Thesis is to investigate the relationships between environmental attitudes and other factors influencing pro-environmental behavior. For this purpose, the data of 210 participants was examined by means of a quantitative online survey. In this study, the short scale UGK-V of the SEU-3 with 21 items was used. It contains seven content scales and measures the constructs attitude, behavioral intention, and self-reported behavior. In addition, three items were used to measure awareness of action consequences. Significant correlations are found between the environment-related constructs. Attitude correlates strongest with behavioral intention. The postulated hypotheses can be confirmed, though this result is of limited accuracy due to the low reliability of self-reported behavior. It was possible to show a relationship between awareness of action consequences and the total scale, as well as all the subscales. This correlates the most with environmental awareness. The hypothesized correlation (H4) represented the smallest correlation, suggesting that awareness of action consequences may be associated with attitude rather than behavior. Causality cannot be established, so the different aspects may influence each other. Interaction cannot be ruled out either. Inconsistent definitions of the constructs in addition to an insufficiently representative sample make a generalization to any population difficult. The results can be compared with the values of the original sources and show valid survey instruments. The study highlights the discussion of the effect of behavior modification to solve ecological problems.

Human health and welfare depend on ecosystem functions and services which are interchangeably connected to biodiversity. Amphibians are one of the most sensitive and vulnerable species to anthropogenic impacts, because of their fast reactions to changing conditions in their surroundings they are often referred to as bioindicator species. Since year 2016 an amphibian population located in the district of Wesel in North-Rhine-Westphalia in Germany experiences drastic changes in population size and composition. To find out if anthropogenic impacts may influence the development of the amphibian population, different methods for assessing the population and biodiversity are used. Data was collected from year 2017 to 2023 with the help of a drift fence with pitfall traps. The amphibian population is evaluated regarding population size, age structure, sex ratio and migration behaviour. Additionally, biodiversity indices are used for a quantitative and qualitative analysis. As last step, the amphibian population is compared to another amphibian population with similar preconditions, but experiencing less anthropogenic pressure. A high reduction of population size and changes in age and sex composition were found for the assessed amphibian population. Moreover, the migration behaviour alternates over time. The found results strongly indicate that the main cause of the negative development is a high anthropogenic pressure. Further intensive conservation and monitoring actions are needed, to restore the amphibian population and avoid the complete destruction.

Die patientenseitigen Beweggründe für die vermehrte Inanspruchnahme wurden dabei bislang nicht hinreichend untersucht (Reinhold et al., 2021). Auf der Grundlage der bisherigen Literatur scheint das Nachfragewachstum jedoch häufig auf Patienten ohne medizinische Notfallindikation zurückzuführen zu sein (Durand et al., 2012). Methode: Im Zeitraum vom 01.10.-30.11.2022 wurde eine quantitative Fragebogenerhebung im BG Klinikum Duisburg durchgeführt. Der Fragebogen besteht aus insgesamt 16 Fragen. Die Datenauswertung basierte dabei auf deskriptiven sowie inferenzstatistischen Analysen und konnte mehrere Unterschiede zwischen einigen Patientengruppen aufdecken. Es wurde ein 95% Konfidenzintervall festgelegt. Ergebnisse: Im Rahmen der Fragebogenerhebung konnten 548 gültige Fragebögen erworben werden. Dabei zeigten sich die Gründe für das vermehrte Inanspruchnahme-Verhalten multifaktoriell. In erster Linie zählten hierzu antizipierte Qualitätsvorteile innerhalb der Notaufnahmen im Vergleich zu ambulanten Versorgungseinrichtungen seitens der Patienten sowie insbesondere die Unkenntnis der Bevölkerung über bestehende Gesundheitsdienstleistungen im Notfall, wie bspw. den ärztlichen Bereitschaftsdienst. Ebenso ist ein genereller Rückgang der Gesundheitskompetenz zu verzeichnen. Diskussion: Grundsätzlich ist eine fehlende medizinische Notfallindikation bei dem Großteil der Notfallpatienten zu verzeichnen. Das rund um die Uhr zur Verfügung stehende Versorgungsangebot der Notaufnahmen zeigt sich äußerst attraktiv für die Patienten und führt nicht zuletzt zu Bequemlichkeitsentscheidungen. Letztlich muss das ambulante Versorgungssystem ausgebaut, die Bevölkerung besser aufgeklärt und der bestehende Status der Gesundheitskompetenz dadurch gefordert sowie gefördert werden.

Hierzu wurde eine Bevölkerungsgruppe mit einer besonders hohen Beanspruchung der Stimme im Beruf untersucht: die Berufssprecher. Die eingeschlossenen Studien umfassen Menschen aus westlichen Industriestaaten – überwiegend Lehrkräfte, aber auch Telefonisten von Notfallhotlines und Callcentern sowie Priester und Pastoren. Ziel der Arbeit ist es, durch eine systematische Literaturarbeit die Prävalenz von Stimmbelastungen in sprechintensiven Berufen von 2002 bis heute zu erforschen. Die Studienlage zeigt, dass es akuten Handlungsbedarf gibt. Alle Studien weisen anhand von Selbsteinschätzungs-Fragebögen eine deutlich erhöhte Prävalenz auf. Die häufigsten Symptome sind Heiserkeit, Stimmermüdung nach kurzem Stimmeinsatz und ein trockener Hals. Frauen sind aufgrund anatomischer Voraussetzungen stärker betroffen. Des Weiteren liegen häufig psychosoziale Belastungen vor. Diese verstärken das ohnehin bereits erhöhte Risiko für Stimmbelastungen bei Berufssprechern. Die hohe Prävalenz von Stimmbelastungen führt zu längeren Regenerationszeiten und einer erhöhten Anzahl von AU-Tagen. Daraus resultieren hohe Kosten für das Gesundheitssystem. Durch die Erforschung der unterschiedlichen Prävalenzarten (Punkt-/Lebenszeitprävalenz) in den in dieser Arbeit eingeschlossenen Studien, ist ein Vergleich der Ergebnisse nur eingeschränkt möglich. Zu den Risiken für die (Stimm-)Gesundheit zählen ein vorherrschendes geringes Bewusstsein über Stimmprävention sowie berufsspezifische Risikofaktoren. Folgen können Stimmverlust (Aphonie), psychische Erkrankungen sowie Arbeits- und Berufsunfähigkeit sein. Die Integration präventiver Maßnahmen in die Berufsausbildung (z.B. Stimmlehre, Stimmhygiene, Stimmtraining) sowie Eingangsuntersuchungen werden dringend empfohlen. Dazu ist eine interdisziplinäre Zusammenarbeit zwischen Fachleuten, Berufsverbänden und Politik notwendig.

N2 - This paper investigates the impact of the Corona pandemic on M&A activities considering the variables M&A volume, M&A value, GDP, and Covid figures. The aim is to analyze the relationships between the development of the pandemic and M&A activities in five European countries (Germany, the UK, France, Italy, and Spain). With an introduction to the literature published so far on the topic, an excellent introduction to the situations around Corona and the M&A market is already offered. The one or other outlooks are already scientifically proven here and have thus also been very for the following analyses and results. In the first step of the research, we analyze M&A volumes and values in the countries under consideration before and during the pandemic. It can be seen that the number of M&A transactions increased overall during the pandemic, but transaction values were very fluctuating in comparison. This observation certainly reflects the general uncertainties and economic challenges of the pandemic. The next step is correlating Covid figures, M&A activity, and GDP. This shows that the pandemic outbreak led to a short-lived decline in M&A activity, as companies acted more cautiously and held back on transactions due to the uncertainty. However, M&A activity rose again as the economic situation in the countries stabilized, and companies were better able to respond to the pandemic. In addition, the impact of GDP on M&A activity is also examined. It can be seen that GDP was affected in all countries due to lockdowns and restrictions on public life. Nevertheless, there was some resilience in the economy as GDP showed an increase in all countries despite the pandemic. The analysis of the correlation between the variables shows that there is a significant relationship between Covid numbers and M&A activity. The higher the Covid numbers were in a country, the more M&A activity was affected. This suggests that the development of the pandemic had a significant impact on M&A activity. Overall, this work shows that the Corona pandemic significantly impacted M&A activity in Europe. The uncertainty and economic challenges led to a short-lived decline in activity, but the overall number of deals increased. The correlation analysis highlights the links between the pandemic and M&A activity and underscores the importance of thoroughly examining the variable factors influencing M&A decisions under Corona conditions.

As a part of the project by Winkelmann et al. (2022), the continuos physiologically structured population model (cPSPM) of P. fluviatilis was established which appeared to have potential points for improvement. In this study, I attempted to modify mortality function of the population model. Hence based on thorough literature research 4 models for mortality estimation mortality as well as the data of life-traits of perch were found. The models include Hoenig-Then (Then et al., 2015), Pauly-Then (Then et al., 2015), Lorenzen (Lorenzen, 2022). and Weibull probability density function as function of weight dependent mortality. The methods were parametrised via arithmetic average of population specific traits and non-parametric least-square method. As a result, the mortality models were compared to each other as well as to the base model. Further on, each mortality model was integrated into cPSPM and stable population was found. At the end only Lorenzen and Weibull models were analysed. As a result of mortality model comparison, it was found that the difference between these models lies mainly in difference of magnitude. Integration of the models into cPSPM showed the potential correlation between the mortality and reproduction. The comparison of simulations results in similarity in population dynamics of our models with experimental data, with main difference in magnitude. Overall results suggest that every model has reason to be applied, and all of them have their own application. In terms of current cPSPM, it would be suggested to consider population dynamics of perch over multiple years period with different mortality method employed for each year to address the issue of variability of population dynamics on yearly basis.

Gamebased Learning through Gamification can serve as a softer alternative to introduce and familiarize learners with, although due to technical limitations, games do not completely replace reliable passive learning methods of learning such as books, lectures, and field practices. The aim of Project Nitratscouts is to develop educational modules concerning Nitrate infiltration from agricultural soils such as the groundwater boardgame, which facilitates learning about nitrate in groundwater, compliance with environmental quality standards, animal husbandry and manure as fertilizer, while also introducing them to agricultural decision-making regarding crop production. The tool offers several ways for playing, enabling players to perceive underlying the issue of Nitrate in groundwater from different perspectives. The tool was tested with 44 participants, in 17 single and 8 competitive game modes. Feedback was collected through survey results, performance evaluation cards, and participants’ verbal remarks and comments. The purpose of this bachelor thesis is to test the methods adopted to create the tool, describe feedback observations on collection by evaluating the learning effect about conflicts of interest based on quantitative and qualitative analyses of quantitative survey responses, performance evaluation cards, examine similarities of verbal feedback and cluster it into groups regarding multiple aspects such as relevance of random events, design and acquired perspective on conflict of interest, and discuss lessons from received feedback.

Aktuell leidet er unter den Veränderungen in der Gesellschaft, wodurch die Herausforderungen an den Rettungsdienst stetig zu nehmen. In diesem Fall sind es die steigenden Einsatzzahlen und -zeiten. Diese können die Risikofaktoren des Berufes, welche die Mitarbeiter physisch und psychisch belasten können, verstärken. Daher ist es wichtig herauszufinden, wie überlastet der Rettungsdienst tatsächlich ist und ob sich die Belastung auf die Gesundheit der Rettungskräfte auswirkt und somit eine Patientengefährdung entsteht. Ziel dieser Bachelorarbeit ist es, eine Übersicht der möglichen Faktoren, welche die Rettungskräfte gesundheitlich belasten und die zu Überlastungen im Rettungsdienst selbst führen, vorzustellen und diese mit Daten einer durchgeführten Umfrage über die tatsächliche Lage des Rettungsdienstes zu vergleichen. Dafür wird eine umfassende Literaturrecherche zu den Themen Gesundheit der Rettungskräfte und gesellschaftlichen Veränderungen durchgeführt. Des Weiteren wird eine Umfrage, welche die Lage des Rettungsdienstes widerspiegelt, erstellt und an Rettungskräfte geschickt. Anschließend werden die Ergebnisse aufgeführt, ausgewertet und mit Hilfe der Literaturrecherche untersucht. Die Ergebnisse der Ausarbeitung zeigen deutlich, dass der Rettungsdienst überlastet ist. Die Überlastung wirkt sich nur auf wenige Rettungskräfte aus, wodurch weiterhin von einer qualitativ hochwertigen notfallmedizinischen Patientenversorgung ausgegangen werden kann. Eine Voraussetzung dafür stellt allerdings die Bereitschaft der Eigenleistung für die Gesundheit der Rettungskräfte dar. Wenn keine Veränderungen wie Umstrukturierung des Rettungswesens oder Aufklärung der Bürger erfolgen, so wird die Überlastung des Rettungsdienstes zunehmen, wodurch sich die Lage des Rettungsdienstes weiter verschlimmern würde. Es würde zunehmend die Gesundheit der Rettungskräfte negativ beeinflussen, wodurch das Risiko einer Patientengefährdung steigt.

The BOW test rig consists of the wheel that is actuated by the electric motor, motor encoder, and laser sensor. The desired outcome is to stabilize the ball around the equilibrium point on top of the wheel. By employing common control design techniques and establishing appropriate Simulink models the controllers for the BOW system were implemented. The dSpace software was used to capture the performance of the controllers, while MATLAB was used for analysis. However, various issues arose during the design and commissioning processes, preventing the state-space controller to achieve the desired outcome. As a result, a performance comparison was conducted based on Simulink models, as the state-space controller design failed to perform adequately on the BOW test rig. These issues were thoroughly explained within the thesis and the implications were summarized in the conclusion.

The study contains different chapters under the main research question with analysis. The first section starts with a brief background description of Sierra Leone's Agricultural sector in the context of livestock management and its contributions to the country's economy, poverty, and food security. Followed by the research objective, a semi-systematic literature review is conducted based on livestock management's impact and poverty reduction, lessons learned, and analysis of the significant constraint and opportunities for the sector's growth was presented using a conceptual framework. In chapter three, the writer uses a qualitative methodology to identify the different sections and data used in the thesis through a thematic approach. The results show that livestock management can contribute to the district's food security, poverty reduction, and wealth creation. However, factors such as poor road networks, weak governmental institutions/policies, insufficient funding, and lack of raw materials, among others, are critical issues affecting the development of the industry. On the other hand, traditional/cultural benefits and income generation are the district's main significant uses of livestock. Therefore, addressing these challenges through comprehensive interventions/policies will enable the people of the moyamba community to benefit from livestock and reduce poverty in the long term.

The major goal of the survey was to assess the small scale and the large scale dairy farmers level of awareness on sustainability or if at all they employed sustainability practices within their farming systems. The feedback from the survey indicated that small scale farmers either knew little or nothing about sustainability practices. Dairy production is an important aspect of the Zimbabwean economy. It assures that some of the nation’s major nutritional requirements are met, farmers are economically empowered, promotes rural development and impacts positively to the gross domestic production. The thesis showed the current level of sustainability obtained at small scale dairy farms, the challenges faced by small scale dairy farmers, as well as multi-stake holder engagement and government role or involvement. Major findings revealed factors that include genetics, animal welfare, feed and feed composition, hazard analysis critical control points and knowledge were key to sustainable dairying with an inclination towards an increase in milk production.

This thesis aims to create a control layer to manage the learning data and depict it on the user interface, as well as a learning path recommendation system to establish a learning path defined by the teacher. The project extends the pre-existing TierschutzErleben platform, utilizing a stateof-the-art specification for learning data, frontend framework, and a video game engine. A main control unit is developed to manage learning data and coordinate elements of the platform. To recommend learning paths, a system is created, and interfaces are established to validate communication. A service is introduced to relay events between components, with events containing instructions for executing appropriate actions on the receiving end. Additionally, a command execution system is implemented to manage these commands. The implementation of a single control layer, composed of the developed services, effectively coordinates data collected from multiple entities. The use of interfaces and the command execution system provides a clear and structured view of events and their corresponding actions.

However, little is known about the interactions between heavy metals and microplastics, as well as possible biological effects when the two are combined. It is possible that MPs and heavy metals can interact in soil, causing changes in their environmental behaviour, bioavailability, and potentially toxic properties, further posing ecological risks. Therefore, the objective of this study was to evaluate the individual and combined impacts of microplastics and heavy metals on soil chemical properties, microbial biomass, microbial activity, and microbial communities in soil treated with varying concentrations of these pollutants. In an incubation experiment, soil was amended with low-density polyethylene (LDPE) and a mixture of heavy metals (Zn, Cu, and Ni) in two concentrations (Low and High). Seven treatments (Control; MP-L; MP-H; HM-L; HM-H; MP+HM-L and MP+HM-H) were analysed in seven replications. The rate of microbial respiration was determined during incubation. Following incubation, soil pH, microbial biomass carbon (C), nitrogen (N), soil fluorescein diacetate hydrolytic activity, and the abundance of archaea, bacteria, and fungi were measured as well as the effects on inorganic nitrogen (NO3-, NH4+) were determined. It was found that no significant difference existed between the control treatment and LDPE treatment in terms of soil pH, FDAse activity, microbial biomass, microbial respiration, inorganic nitrogen, and abundance of archaea, bacteria, or fungi, regardless of the concentration of LDPE (0.6%, 1.2%). Heavy metal treatment did, however, result in a significant decrease in soil pH, NO3, and microbial respiration particularly at high concentrations (2.68 mg kg-1), compared with treatments with LDPE and a control, suggesting that HMs suppressed microbial activity. Additionally, HMs also reduced MBN and MBC, indicating their negative effect on microbial biomass. As a result of the combination of microplastics and heavy metals, microbial biomass, and microbial respiration decreased significantly when compared to either the control treatments or the microplastics alone treatment. Additionally, the combined treatment reduces NO3- and soil pH significantly compared to the control and sole microplastic treatment There was no significant effect observed in any treatment on the abundance of archaea or fungi, indicating that the presence of MP and/or HMs had no impact on their abundance. However, the MP+HM treatment resulted in a reduction in the number of bacteria. Using a two-factor statistical analysis, the effect of two concentrations (low and high) of microplastics and/or heavy metals on these soil parameters was further evaluated. According to these results, the concentrations of added microplastics and/or heavy metals (low and high) had no significant effect (p > 0.05) on any soil parameter except for soil pH (p < 0.05). Overall, the results indicate that the presence of heavy metals, either alone or combined with microplastics, had a detrimental effect on soil ecosystem. However, this study was limited to examining the short-term effects of these pollutants on soil microorganisms and their functioning. Additional research will be necessary to determine the long-term effects of these pollutants.

In this growing trend, more and more scientists are trying to surf over the waves of bio-inspired solutions, but the fundamental differences between nature’s point of view and man-kind, on managing the resources and solving problems, has made the traditional equipment’s of scientist, obsolete; especially when it come to actuation methods. Since the traditional device and component are not suitable for cutting edge fields, such as bio-inspired robotic, artificial muscles, soft robotic and so on; this thesis has offered an especially designed syringe pump, to fulfill this need. Starting from the basic constraints and expectations for such syringe pump, a morphological box has been shaped in this project; and along with having an eye over relatively similar products in the market, borders of “design function” has been drawn. By considering the available equipment and tools for production of such device, the “design concept” of this thesis has been formed. And finally, after days of manufacturing, the prototype of this concept has been brought to life. In this syringe pump, a stepper motor (NEMA-17) is controlled by combination of computer, Arduino UNO and microstep driver DM542; by powering this stepper, a lead screw will be driven. Designing an aluminum structure and connecting a lead-nut to the lead-screw; linear displacement can be produced. This linear displacement is responsible for movement of a tray, which is holding onto the end of syringe’s plunger; and by clamping the cylinder to the designed station of the thesis; with this configuration, desired static pressure can be produced by displacing the plunger. Having this static pressure, is the key feature for simulating many different biomimetics projects, such as soft robotics and artificial muscles. As the results, this thesis has achieve the high precision and resolution of “100 𝜇m” for each 5 steps of stepper motor, equivalent to 9° of rotation. Furthermore, the prototype have easily and quickly delivered 300 mmHg (39.99Kpa), by using only a single 20ml syringe; and reached the highest speed of 750 rpm for the stepper motor.

Such interactions and the occurrence of side effects due to incorrect dosages are also known for the antidepressant bupropion, emphasizing the importance of therapeutic drug monitoring for this medication. Therefore, this study aimed to develop and validate a method for the determination of serum levels of bupropion and its pharmacologically active major metabolite, hydroxybupropion, using LC-MS. Additionally, due to the low stability of bupropion at room temperature, the influence of this factor on the routine measurements of bupropion patient samples in the laboratory of the LVR-Klinik Viersen pharmacy was also examined. Various bupropion solutions (dissolved in methanol or human albumin) were prepared for measurement. These solutions were analyzed using an LC-MS "Exactive Plus Orbitrap" with a biphenyl column as the stationary phase and various mobile phases differing in polarity to allow for the generation of a gradient. An electron spray ionization (ESI) method and an Orbitrap detector were used for quantifying the sample concentration. The measurement of a 0.1 ng/ml bupropion solution and a 0.5 ng/ml hydroxybupropion solution resulted in a signal-to-noise ratio in the mass spectrum that was well above the required 3:1 ratio for background noise subtraction. As the concentration was already below the required detection limit of 0.2 ng/ml for bupropion and 17 ng/ml for hydroxybupropion, no further steps were taken to determine the actual limit of detection for economic reasons since sufficient sensitivity of the LC-MS method was already demonstrated. The investigations into the recovery rate (WFR) and ion suppression showed that the applied sample preparation (protein precipitation with acetonitrile) did not lead to any relevant loss of content and that no interfering effects from other components of the sample matrix occurred during the measurement. The WFR was determined to be 100 ± 5% for bupropion and 101 ± 4.8% for hydroxybupropion. The examination of ion suppression resulted in a content deviation from the target value of 4 ± 0.2% for bupropion and -9 ± 0.1% for hydroxybupropion. The linearity of the method was confirmed by measuring a 5-point calibration with a correlation coefficient for the regression line of approximately 0.99 for both analytes. The precision and reproducibility of the method were also confirmed through the evaluation of in-day and day-to-day variation, with a coefficient of variation of <10 for all measurements conducted for both analytes. Thus, a reliable method for the determination of bupropion content using LC-MS was successfully developed and validated. By participating in proficiency testing programs, the method will be further validated and potentially certified in the future. N2 - Patienten in psychiatrischer Behandlung werden in der Regel mit einer Vielzahl von Medikamenten behandelt, deren Wechselwirkungen und der daraus resultierende Einfluss auf die Serumspiegelkonzentration der Arzneistoffe nicht vorhersehbar sind. Auch für das Antidepressivum Bupropion sind solche Wechselwirkungen, sowie das Auftreten von Nebenwirkungen aufgrund falscher Dosierungen in der Therapie bekannt und unterstreichen die Bedeutung des therapeutischen Drug Monitorings für diesen Wirkstoff. In dieser Arbeit sollte daher eine Methode zur Serumspiegelbestimmung von Bupropion und seinem pharmakologisch wirksamen Hauptmetaboliten Hydroxy-Bupropion für die LCMS entwickelt und validiert werden. Aufgrund der geringen Stabilität von Bupropion bei Raumtemperatur, sollte zudem überprüft werden, welchen Einfluss dies auf die Routinemessungen von Bupropion-Patientenproben im Labor der Apotheke der LVR-Klinik Viersen hat. Es wurden verschiedene Bupropion Lösungen (in Methanol oder Humanalbumin gelöst) für die Vermessung hergestellt. Diese wurden auf einer LCMS „Exactive Plus Orbitrap“ unter Verwendung einer Biphenyl-Säule als stationäre Phase und diverser Fließmittel, die sich in ihrer Polarität unterschieden und so die Erzeugung eines Gradienten ermöglichten, analysiert. Als Ionisationsverfahren kam eine Elektronensprayionisation (ESI), sowie ein Orbitrap-Detektor zur Quantifizierung der Probenkonzentration zum Einsatz. Die Vermessung einer 0,1 ng/ml Bupropion-Lösung und einer 0,5 ng/ml Hydroxy-Bupropion-Lösung ergaben ein Signal-Rausch-Verhältnis im Massenspektrum, welches weit über dem erforderlichen 3:1-Verhältnis für die Abhebung vom Hintergrundrauschen lag. Da die Konzentration bereits unterhalb der erforderlichen Messempfindlichkeit von 0,2 ng/ml für Bupropion bzw. 17 ng/ml für Hydroxy-Bupropion lag, wurden aus wirtschaftlichen Gründen keine weiteren Schritte zur Bestimmung der tatsächlichen Nachweisgrenze unternommen, da eine ausreichende Empfindlichkeit der LCMS bereits belegt war. Die Untersuchungen zur Wiederfindungsrate (WFR) und der Ionensupression konnten zeigen, dass die verwendete Aufbereitung (Proteinfällung mit Acetonitril) zu keinem relevanten Gehaltsverlust führt und keine störenden Effekte durch andere Bestandteile der Probenmatrix während der Vermessung auftreten. Es ergab sich eine WFR für Bupropion von 100 ± 5 % und für Hydroxy-Bupropion von 101 ± 4,8 %. Bei der Untersuchung zur Ionensuppression kam es zu einer Gehaltsabweichung vom Zielwert von 4 ± 0,2 % für Bupropion und von -9 ± 0,1 % für Hydroxy-Bupropion. Die Linearität der Methode wurde durch die Vermessung einer 5-Punkt-Kalibration mit einem Korrelationskoeffizienten für die Regressionsgerade von ~0,99 für beide Analyten bestätigt. Durch die Überprüfung der In-Day- und Day-to-Day-Variation konnte auch die Präzision und Reproduzierbarkeit der Methode bestätigt werden. Dabei ergab sich ein Variationskoeffizient für alle durchgeführten Messungen von <10 für beide Analyten. Somit konnte erfolgreich eine zuverlässige Methode für die Gehaltsbestimmung von Bupropion mittels LCMS entwickelt und validiert werden. Durch das Integrieren von Bupropion in die Teilnahme an Ringversuchen, wird die Methode in Zukunft auch weiter validiert und ggf. zertifiziert werden.

The potential benefits and drawbacks of soil amendment with frass N2 - Insect rearing is a rapidly growing sector in Europe, with larval protein production projected to exceed 1 Mt in 2025. The by-product frass is a mix of larval faeces, exoskeletons and undigested substrate. Given its potential as a soil improver, frass could make insect production a “zero waste” industry. However, its positive reputation has not been thoroughly scrutinized with regard to environmental impacts. We therefore conducted experiments to investigate the effects of frass application on the soil microbial community, release of greenhouse gases and heavy metal availability. The main conclusions were: 1) Frass is nutritious and can benefit the soil microbial biomass, but rapid loss of C and N reduces its fertiliser and organic amendment potential 2) Co-application of frass with urease inhibitors could allow it to be utilised as a slow-release N fertiliser 3) Concurrent soil amendment of frass with nitrification inhibitors prevents soil nitrite accumulation 4) All frass types tested are suitable as ameliorative amendments to heavy-metal contaminated soils T3 - Beiträge des Forschungs- und Transfertags der Hochschule-Rhein Waal - 05 Y1 - 2023 U6 - http://nbn-resolving.de/urn/resolver.pl?urn:nbn:de:hbz:1383-opus4-17689 ER - TY - CHAP A1 - Hansen, Ute A1 - Huth, Miriam A1 - Platte, Frank A1 - Stawicki, Piotr A1 - Struck, Alexander A1 - Tewes, Thomas A1 - Wenda, André T1 - Entwicklung innovativer Verfahren zur mikrobiologischen Qualitätsüberwachung in Echtzeit N2 - Entwicklung biophysikalischer Verfahren zur schnellen Identifikation mikrobieller Kontaminationen in Gewässern – Vorstellung des InnoMiBiQ-Projektes Ute Hansen1, Miriam Huth2, Frank Platte2, Piotr Stawicki3, Alexander Struck3, Thomas J.

Ziel des InnoMiBiQ Projektes ist die Entwicklung eines schnellen biophysikalischen Verfahrens zur Identifikation mikrobieller Kontaminationen in Gewässern. Gefördert wird das Projekt mit zweijähriger Laufzeit im Rahmen des Focus Forschung HAW Programms des Ministeriums für Kultur und Wissenschaft des Landes Nordrhein-Westfalen. Die Förderlinie FF HAW-Kooperation zielt auf eine verbesserte HS-interne interdisziplinäre Kooperation und den Auf- und Ausbau eines attraktiven Forschungsschwerpunkts. Ausgangspunkt der Arbeiten war das in der Arbeitsgruppe von F. Platte und in Kooperation mit der AG Hygiene (Prof. Bockmühl) von T. Tewes entwickelte Verfahren zur Identifizierung von Mikroorganismen mit Hilfe der Raman-Spektroskopie. Experimentelle Arbeiten wurden zu der Frage durchgeführt, ob die Methodik für die Identifizierung einzelner Bakterien in Gewässerproben anwendbar ist und welche Probenvorbehandlungs- und Datenverarbeitungsprozeduren unter Berücksichtigung der Automatisierbarkeit erforderlich sind. Die Ergebnisse bzgl. der Raman-spektroskopischen Identifizierung der Bakterienzellen waren vielversprechend. Problematisch ist allerdings, dass es gilt, wenige bakterielle Zellen zwischen einer sehr großen Zahl anderer Partikel zu identifizieren. Ideen für ein Raman-basiertes schnelles Partikel-Scan-Verfahren wurden entwickelt. Untersucht wurde auch, ob neben Mikroorganismen weitere Wasserkontaminationen mit Hilfe der Raman-Spektroskopie nachweisbar sind. Hier standen Verunreinigungen durch Mikroplastik (speziell Reifenabrieb), Ölfilme, Sulfat und Nitrat im Mittelpunkt. Im Rahmen zahlreicher „networking“-Aktivitäten wurden Kontakte zu Herstellern von Partikelmess-Systemen aufgebaut und Kooperationen mit Anbietern von Raman-Spektrometern initiiert mit dem Ziel, über F&E Projekte die Entwicklung eines kontinuierlich arbeitenden des Raman-Systems voranzubringen. Projektskizzen wurden entwickelt und Anträge auf Forschungsförderung eingereicht. Dass schnelle, kontinuierlich arbeitende biophysikalische Verfahren zur Identifikation von Gewässer-Kontaminationen erforderlich sind, wurde von potentiellen Anwendern bestätigt. Nur eine zeitlich hoch aufgelöste Überwachung der Wasserqualität kann Katastrophen wie das Fischsterben in der Oder verhindern.

Duties such as corporate social responsibility reporting as well as shifting customer demands are placing increased pressure on the association events industry to acknowledge the importance of sustainability and implement sustainable event management strategies. Association events tend to have an economic, social and environmental impact on the places in which they occur. These impacts can be both positive and negative. They can also have substantial leveraging and multiplier effects, can be used to elevate awareness of sustainability even further and, most importantly, help transform this awareness into action, for example by influencing stakeholders’ behaviour and minimising behavioural gaps. The events and meetings industry has traditionally relied on economic performance measures, eschewing social and environmental costs and benefits. However, recent studies have underlined the necessity for a more holistic approach. This approach is fleshed out in the present research. It aims to offer stakeholders, decision-makers, event managers, associations and congress organisers a strategical instrument with which to identify the economic, social and environmental impacts of a planned event in order to utilise them in a targeted, sustainable fashion within the respective field of operation. The strategic measures for optimising event impacts were derived from the results of the empirical study. Moreover, these measures will serve to anchor the sustainable association event strategy within business operations as well as internal and external communications. Gifford’s Dragons of Inaction can be applied to determine possible barriers and, finally, to strive to minimise the gap between sustainability consciousness and sustainable behaviour. To this end, the effectiveness of cooperating attitudes, behaviour-oriented forms of intervention such as intentions or incentives for actions, and perceived consequences can be assessed and evaluated in terms of their essential dimensions. Methodology A number of research steps have been undertaken within this model, beginning with a literature review. This laid the foundation for subsequent empirical studies conducted as semi-structured expert interviews, followed by an online Delphi forecast as well as a survey among participants of an association event of the German Scouts (DPSG). Findings As shown in the primary research in both studies, social and economic measures are regarded as most important, environmental measures are most often adopted instead. Not all dimensions are considered to be part of sustainability. Social and economic aspects are considered necessary for an association’s success and are considered important strategic instruments connected mainly to positive implications on a psychological level such as image, trust and satisfaction. As it is seen as a competitive advantage and the terminology is unclear to many in the event industry, communication efforts must be targeted in order to facilitate implementation and, later, allow for the possibility of measuring sustainable event management. Holistic aspects should be made clear in order to support initiatives and ideally reduce the behavioural gap between sustainability awareness and actual behaviour. Associations like the German scouts are risk-averse by nature. They function as custodians of a sector or profession and their standards demand continuity as well as consistency. Innovation, however, is associated with risk, experimentation and (superfluous) change. Both primary and secondary research efforts have shown that barriers to innovation include a lack of time, resources (money or staff in particular), or simply innovation know-how. Therefore, implementing change or, in this case, more sustainable measures in event planning, requires an individual, tailor-made approach which is pro-active and problem-solving in order to promote broader implementation of the already developed Green Events Guidelines throughout the whole association. The findings of this mixed-method approach were used to develop a model to integrate, assess and steer event management sustainability from the perspective of event planners and associations, and propose a new concept for converting theory into applied practice for the industry.

In Germany, this self-governance approach influenced the political discussions and led to a more integrative and collaborative multi-policy strategy beyond pure regulatory regimes. The launch of the German CDR-code by the German action group in June 2021 is a milestone to capture ethical problems in digitalised firms by voluntary commitments from signatories. However, little empirical evidence on the current state of CDR-initiatives at German corporations is available up-to now. This project addresses the identified research gap by performing a qualitative analysis of the disclosed information on CDR in nonfinancial reports of the DAX 30 companies from 2020.

Despite the fact that groundwater is frequently abundant and widely utilized, it is difficult and costly to precisely estimate water levels when compared to surface water systems. Groundwater managers require improved digital tools to understand the system state of the aquifers they seek to interact with sustainably (e.g., accessing real-time updates on the state of the water table to check whether pumping operation is achieving or violating a desired drawdown target.) Here we propose a workflow for a pilot region that (a) temporally interpolates irregularly, manually-measured water levels in a real observation network using data from neighboring sensor-equipped observation, using a multiple linear regression approach to reduce complexity. The resulting interpolated time series are then used in conjunction with the sensor data to come up with (b) spatial interpolations of the groundwater field over time using inversed distance weighting (IDW) at any given point in time. From that, spatial estimates of the groundwater field can be transformed into maps of deviation from drawdown targets. We visualize these targets and their temporal evolution for groundwater managers in real-time on a web application. The web application displays these maps together with operational data (e.g., extraction rates) and meteorological data (recent and forecasted precipitation rates). It serves as a foundational tool for groundwater management when making control decisions to save energy in climate change mitigation and to reduce costs.

Deep learning is increasingly used for modeling complex systems, which generates more interest in battery state estimation. The theoretical investigation of candidate neural networks for SOC estimation is preceded an experimental approach to evaluate the shortlisted neural networks performance. Publicly available testing datasets representing real driving cycles has been used to train the selected networks, taking into consideration different operating temperatures for the exact cycles. Testing the prediction capability of the models across a realistic range of operating conditions is the driving factor for including testing cycles with a temperature range of [0–40] °C in the training datasets. A demonstration of the full training cycle is conducted, along with the optimization problem of network parameters. This work demonstrates the applicable neural network family used for training this kind of sequential data, followed by the shortlisting of two neural networks based on their performance using literature research. After selecting the networks, finer evaluation criteria is applied, including both their prediction capability and training requirements. The results show that both networks, long short-term memory (LSTM) and gate recurrent units (GRU), offer satisfactory prediction capability with mean absolute error (MAE) of (2.9%, 2.7%) respectively, when averaged across the tested temperatures. The GRU network on the other hand had significantly higher resource requirements and a more complex architecture. Finally, a more recent architecture is briefly discussed, borrowing the strength of a parallel application field. The scope of this work is to highlight both the capabilities and cost of training deep learning networks for SOC estimation.

The properties and characteristics of this offshore wind farm areas were compared to the characteristics of marine protected areas and differences as well as conformities were highlighted. It is evident, that the negative consequences accompanying the implementation of offshore wind farms are less concise, than the public opinion assumes. Although scientific knowledge gaps in multiple related fields for example, the influence of elec- tromagnetic fields on individuals or the influence of noise on benthos species, are present, offshore wind farms offer chances to contribute positive effects for marine life in terms of de facto protected areas and new possibilities for population growth. The planned extensions of offshore wind farms in geographical relation to marine protected areas could enhance the size of protected areas and connect remote ma- rine protected areas with each other.

Durch die Schülerumfrage konnte der Einfluss des Projekts auf die Wahrnehmung der Schüler:innen mit einem leicht negativem Ergebnis untersucht werden, H3 kann also nicht bestätigt werden. Abschließend lässt sich festhalten, dass Dachbegrünungen eine wertvolle ökologische Maßnahme darstellen. Es sind umfangreiche Einflüsse auf verschiedene umweltrelevante Bereiche möglich. Darüber hinaus eignen sich Dachbegrünungen vor allem an Schulen auch aufgrund ihres pädagogischen Mehrwerts. Zukünftig werden ähnliche Projekte hoffentlich in einem steigendem Ausmaße ihren Anteil zum Klimaschutz beitragen. Y1 - 2023 ER - TY - THES A1 - Steup, Maike T1 - Untersuchung der Präferenzen der Generationen Z und Y bei der Arbeitgeberwahl unter Betrachtung der Arbeitgeberattraktivität - eine empirische Untersuchung N2 - Das Ziel der vorliegenden Bachelorarbeit ist die Präferenzen der Generation Z und Y gemessen an der Arbeitgeberattraktivität zu analysieren und entsprechend zu vergleichen. Dazu wurden 93 Studierende in einer quantitativen Onlineumfrage befragt. Die Umfrage basiert auf der Employer Attractiveness Scale von Berthon, Ewing & Ha aus dem Jahr 2005 sowie auf der Authentic Living Scale von Wood et al. aus dem Jahre 2008. Ergänzungen wurden in den Bereichen ethischer Diversität, Unternehmenskultur, Glaubwürdigkeit, Authentizität und persönliche Werte vorgenommen. Diese Aspekte sind im Fragebogen von Berthon, Ewing & Ha im Vergleich mit anderen Arbeitsattraktivitätsmodellen, beispielsweise das Treiberfaktorenmodell von Nagel (2011), unterrepräsentiert, haben allerdings laut einer umfassenden Literaturrecherche für die jungen Generationen Z und Y an Wichtigkeit zugenommen. Die Ergebnisse liefern einen umfassenden Vergleich zu allgemeinen Aspekten der Präferenzen beider Generationen an den Arbeitgeber. Die jungen Generationen unterscheiden sich nur leicht voneinander, was aufwändige Anpassungen an HR-Strategien und Praktiken nicht notwendig macht. Die Bachelorarbeit ist für jegliches Unternehmen interessant, das ihre Zielgruppen (Generation Y & Z) zum Zweck der Rekrutierung besser verstehen möchte. Die Ergebnisse können in Recruiting- und Employer Branding Maßnahmen adaptiert werden.

This research aims to develop a smart gas burning system built on reliable and secure communication channels bounded with the implemented protocol specifications. A close study of each protocol specifications as well as a bit-by-bit investigation is therefore performed, moreover, a full timing analysis of communicated data is also carried out to ensure validity and integrity of the data transmitted. It was found that logic analysis plays a very important role in constructing data frames that are accurate to the smallest time unit possible, such analysis was not possible using an old model oscilloscope, after successful construction, transmitting a predefined sequence of data successfully initiated the communication channel between all system components. With the implemented safety and security features, the system is safe to use, however, this does not make it ready for end users, this is merely a proof of concept that such system can be made smart. The results show that the microcontroller module implemented is very capable of giving the user the ability to control the system manually with attached knobs and wirelessly through the Access point server. Y1 - 2023 ER - TY - THES A1 - Fischer, Alexander T1 - Workplace Health Promotion through Physical Activity Programs Private Economic Return: A Prospective Partial Cost Benefit Analysis for German Firms N2 - Increasing levels of inactivity in contemporary work and lifestyle and the consequent rise in chronic disease have necessitated public health intervention, delivered particularly through the workplace setting. The purpose of this thesis is to provide information on the economic ramifications of such workplace health promotion programs in the field of physical activity to allow for data-based investment decisions of firms. Within a cost-benefit evaluation framework, this thesis identified relevant costs and benefits from practically oriented literature. While most outcomes have been found inconclusive, reductions in absenteeism might be appropriately evidenced and sufficiently tangible to allow quantification. Based on population-attributable risk and insurance data, per employee 0.38-0.58 absence days, or 47.17-71.08€ were estimated to be solely attributable to physical inactivity. Oppositely, cost magnitude depends largely on the interventions’ format, cost-effectiveness, and especially the time investment of the participant. Yet, the economic evidence is largely restricted and demands further investigation.

Der Mediierende Effekt digitaler Selbstwirksamkeit auf die Beziehung zwischen Alter und Arbeitszufriedenheit. N2 - Die kontinuierliche Digitalisierung der Arbeitswelt führt zu immer schnelllebigeren und komplexeren Arbeitsumfeldern, welche auf der effektiven Nutzung von Informations- und Kommunikationstechnologien (IKT) beruhen. Arbeitsfelder transformieren und verdichten sich mit rasanter Geschwindigkeit. Parallel steigt das durchschnittliche Alter der arbeitnehmenden Population und die Arbeitszufriedenheit sinkt. Besonders betroffen sind Erwachsene gehobenen Alters. Da die Arbeitszufriedenheit als starker Prädiktor für die physische- und psychische Gesundheit der Arbeitnehmenden wirkt, ist es notwendig zu verstehen, welche Konstrukte auf die Arbeitszufriedenheit wirken. Die vorliegende Studie betrachtet daher die mediierende Wirkung der digitalen Selbstwirksamkeit auf die Beziehung zwischen Alter und Arbeitszufriedenheit. Es wurde eine online-Befragung mit 124 Arbeitnehmenden im Alter von 17-63 Jahren durchgeführt. Es wurde erwartet, dass steigendes Alter in einer negativen Beziehung zu Arbeitszufriedenheit und digitaler Selbstwirksamkeit steht. Zusätzlich wurde angenommen, dass digitale Selbstwirksamkeit positiv auf Arbeitszufriedenheit wirkt. Es wurde eine indirekte Mediation, mit einer negativen Wirkung von Alter auf Digitale Selbstwirksamkeit und einer positiven Wirkung von digitaler Selbstwirksamkeit auf Arbeitszufriedenheit identifiziert. Die Wirkung der Geschlechtsidentifikation als Störvariable konnte ausgeschlossen werden. Praktische und theoretische Implikationen werden diskutiert.
