However, hydrogen's "clean" reputation is questionable due to its main production method of steam methane reforming (SMR), which produces large quantities of CO2 emissions. To abide by recent international regulations, the production of hydrogen needs an immediate transition to low-emission production methods. A promising solution is the thermo-catalytic decomposition of methane (TCMD), which thermally decomposes methane into hydrogen gas and solid carbon without any direct GHG emissions. The problem with this process is that the catalyst deactivates quickly and therefore must be replaced periodically for sustained hydrogen yields. This results in high catalyst turnover costs, which is the main bottleneck in the successful commercialisation of this process. By developing a simplified model using the most commercially viable parameters and linking the turnover costs with the deactivation of the catalyst, this study aimed to accelerate the adoption of the TCMD process by better enabling companies to analyse the feasibility of their potential low-emission TCMD solutions. The most commercially viable solution featured the use of a fluidised bed reactor (FBR) for continuous operation with an iron-based catalyst due to their low-cost. Catalyst regeneration was found to be ineffective and the best method for mitigating catalyst deactivation was the optimisation of the process conditions. A simplified mathematical model was then constructed to enable this adjustment to maximise the production of hydrogen and minimise the turnover costs. This model was based on the ideal continuous stirred tank reactor but incorporated the fluidising behaviour through several variables including the development of the novel "Fluidisation Factor". An optimisation ratio was also developed to quantify the simulation results and obtain the optimal conditions. The results showed that the ideal conditions for this process was at the highest temperature before the catalyst starts to sinter (≈950ºC) and at the maximum pressure. The largest catalyst particle size of 150 𝜇m and the maximum amount of catalyst was found to allow for higher fluidisation velocities and to delay the deactivation time respectively. The inlet gas velocity and the catalyst activity limit were found to be highly dependent on the hydrogen production rate and therefore due to the conditions used in this study the optimum inlet gas velocity was 10\% of the fluidisation velocity range (and composed of pure methane), whilst the optimum activity limit was at 22\% activity. Lastly, a comparison of the heating method found that controlled heating was more suitable than constant heating due to the stable temperatures during deactivation, which prevent catalyst sintering. Comparing the optimised results from this study with the SMR production method found that the estimated catalyst turnover costs were 10¢/kg H2 and 18¢/kg H2 respectively. This demonstrates that the simplified model developed in this work can better enable companies to optimise and assess the feasibility of their proposed TCMD solutions and help transition their hydrogen production processes to cleaner alternatives.}, language = {en} } @masterthesis{Gole, type = {Bachelor Thesis}, author = {Gole, Rutu}, title = {Right to Information in the Republic of India: At the Intersection of Social Inequality}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-8937}, school = {Hochschule Rhein-Waal}, pages = {76}, abstract = {'Right to Information in the Republic of India: At the Intersection of Social Inequality' seeks to explore the interrelationship between the exercise of the right to access state-held public information and social inequality in India. A large body of literature suggests that social inequality impacts the accessibility of democratic rights while the democratization of rights strengthens civil society and anchors the process towards social equity. Drawing on this hypothesis, the methodological framework of documentary research is employed for examining the social realities surrounding India's Right to Information Act since its inception in 2005. To meet the research objective, numerous public documents that contain quantitative and qualitative data published by the government of India, experts in the field and recognized national and international organizations are referenced.

The study area included the North-west, Southwest, Littoral, Central and West regions of Cameroon. Data was collected through surveys and interviews with key informants and between the months of March and August 2021. A sample of 457 Value chain actors com-prising 163 farmers, 105 traders, 70 processors and 119 consumers was se-lected through a simple random sampling procedure. Secondary data was col-lected from published studies and from some officials of the Ministry of Agricul-ture. Data analysis was done using Microsoft Excel. Social Network Analysis, Functional institutional Analysis and the French Systematic method were used to analyse the structure of the value chain. Demographic and production char-acteristics were analysed by means of descriptive statistics. Profitability analy-sis was used to determine the profit margins of value chain actors. The results of the study revealed that 47\% of farmers were males and 53\% were females and that 77.1 \% of traders and 65.3\% of processors had attained at least sec-ondary level of education. Farm sizes ranged from 0.4 - 3 hectares and 81\% them practiced mixed cropping. The shortest marketing (from farmers - con-sumer) was the most used channel. The calculated average yield of cassava was 9.25 t/ha and that for sweet potatoes was 7.65 t/ha. Pre-harvest loss stood at 4.7\% and the total post-harvest loss was 17.6\% for sweet potatoes and 5.8\% for cassava. The gross profit per hectare for cassava farmers was 63,069 FCFA and for sweet potato farmers it was 697,134 FCFA. The monthly gross profits for cassava traders (469,342 FCFA) were greater than that of processors (212,587 FCFA). The overall performance of the value chain was considered low due to poor record keeping, low profit margins, high percentage of post-harvest losses, few number of processed products, and poor chain governance}, language = {en} } @masterthesis{Rademacher, type = {Bachelor Thesis}, author = {Rademacher, Marian Evelin}, title = {Entwicklung eines Modells zur Untersuchung des Einflusses von pr{\"a}biotischen Wirkstoffen und Konservierungsmitteln auf das Hautmikrobiom}, school = {Hochschule Rhein-Waal}, abstract = {Der gezielte Einsatz von pr{\"a}biotischen Wirkstoffen in kosmetischen Produkten, zur Verbesserung des Hautbildes mittels Beeinflussung des Hautmikrobioms, wird zunehmend verfolgt.

These chemicals exert stress on soil microorganisms, affecting the biodegradation of herbicides. There has been little research examining herbicide degradation in the presence of another herbicide from the perspective of stress response using carbon-use efficiency (CUE) to quantify the modified metabolic processes. We investigated, in a 25-day incubation experiment, the effects of the herbicide 2-methyl-4-chlorophenoxyacetic acid (MCPA), as an additional chemical stressor for soil microbes, on the degradation of glyphosate, by determining the 13C-labelled glyphosate-derived CO2 (G-derived CO2), 13C-labelled glyphosate incorporated into microbial biomass (G-derived Cmic), and finally the CUE. We observed statistically higher G-derived CO2 in the combined herbicide treatment compared to the treatment with only glyphosate. The G-derived Cmic was lower in the combined treatment than in the glyphosate only treatment, but the difference was not statistically significant. The CUE of soil microorganisms was lower in the combined treatment, but the results were not significant. Despite the statistical insignificance, a clear trend exists that suggests a more catabolic microbial metabolism under stress induced by the presence of a second herbicide MCPA.}, language = {en} } @masterthesis{Mueller, type = {Bachelor Thesis}, author = {M{\"u}ller, Felix}, title = {Alternative Performance Measures in Board Compensation - Theoretical Analysis and Empirical Investigation of German DAX Companies}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-7178}, school = {Hochschule Rhein-Waal}, pages = {69}, abstract = {This work investigates in how far Alternative Performance Measures (APM) are suitable to serve as the benchmark for achievement of financial targets by board members of stock-listed companies. Therefore, the concept of board compensation is outlined, the phenomenon of APM is defined, and the main points of scholarly interest in both subject areas are addressed. Through reviewing existing literature that investigates the use of APM within board compensation systems, the rationale for their use and the associated (dis-)advantages are determined. It is shown that the use of APM in board compensation can lead to greater alignment between board members and shareholders' interests, in-crease sensitivity of pay to performance, and improve the information content of APM published elsewhere. However, using APM can also lead to excessive pay, which may be a result of managerial opportunism. Strong corporate governance mechanisms ap-pear to be relevant for ensuring an appropriate use of APM in compensation systems. The use of APM within board compensation schemes of large German stock-listed com-panies in the fiscal year 2019 is investigated empirically. The relevance of such measures is found to be high, and they determine a large portion of total variable pay. The specific APM used within compensation schemes and those disclosed in annual reports are partially divergent, especially when it comes to growth-related, capital effi-ciency-related, and capital structure-related measures. Nonetheless, APM used in com-pensation systems are identified as a subgroup of APM disclosed in the annual report.}, language = {en} } @misc{Meisen, type = {Master Thesis}, author = {Meisen, Sabrina}, title = {Modellierung von Ertrag und Wassergehalt von Bienenhonig aus meteorologischen und geographischen Parametern}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-6001}, school = {Hochschule Rhein-Waal}, pages = {78}, abstract = {Die Witterung nimmt Einfluss auf Volkentwicklung, Ausmaß des Befalls mit Varroamilben (V. destructor) und {\"U}berwinterungserfolg von Bienenv{\"o}lkern, sowie auf die Bl{\"u}te nektarsekretierender Pflanzen.

The design concept comprises of a closed loop feedback control system where light dependent resistors will be utilized as sensory components sending a microcontroller feedback signals containing information regarding the sun's light incident intensity. If the sun's light intensity decreases from a pre-specified intensity value, the microcontroller will send a signal to the relevant motor, adjusting the position of the sunshade. Two separate poles will control the movement of the sunshade. The lower pole is fixed and inserted inside a plate, rotating around its own axis dictated by a stepper motor, hence allowing rotation that follows the sun's natural azimuth angle. The upper pole is connected to the lower pole through a pin joint and will follow the sun's natural elevation angle dictated by a second stepper motor. Aluminium Alloy 6061 was chosen as our pole material due to its relatively high strength to weight ratio in addition to its durability, consequently achieving the desired portability and long lifespan of the product. Assessments conducted throughout this project proved the material's ability to support the design structure and external loads subject to it. The structure will be foldable and be conveniently carried with a multifunction bag with simple installation steps to make the product user friendly.

The present paper aims to explore the impact of influencer marketing on consumer behaviour in order to offer novel insights to the literature on influencer marketing and to provide the practitioners with meaningful knowledge in the domain. Specifically, the research investigates in-depth how this marketing strategy influences the consumer behaviour during the consumer decision making process and how factors of different nature such as influencers' trustworthiness, consumers' self-esteem and wishful identification as well as sales promotions affect their behaviour. This study applied an inductive, qualitative approach because of the exploratory nature of the research purpose. The empirical study was conducted by means of semi-structured interviews with ten young female adults from the Republic of Moldova. The interviews concentrated on respondents' personal experiences and attitudes regarding influencer marketing and it researched particularly the beauty and fashion industries on Instagram. The findings of this study uncovered and explained the buying behaviour patterns of female consumers that appear as a result of influencer marketing influence throughout the consumer decision making process.

Zinc is an essential mineral for the production of alcohol as it is a co-factor in alcohol dehydrogenase, the enzyme responsible for alcohol production in yeast. The general consensus of zinc levels needed for yeast fermentation is 0.4 - 1.07 PPM (Nicola and Walker, 2011). METHODS: Data was collected using a refractometer of the brews. There were five brews in total, one with yeast nutrient, two with zinc sulfate at 0.5 PPM and two at 1PPM along with their controls. RESULTS: A total of 25 brews, in five groups of five, were performed. The results showed that supplementing the yeast with commercial yeast nutrient significantly improved the fermentation rate, while zinc sulfate at 0.5 and 1PPM showed no significant difference when compared to the controls. CONCLUSIONS: While a certain level of zinc is needed for fermentation, this study did not find supplementing homebrew cider with zinc sulfate to significantly improve the fermentation rate in comparison with control brews. When compared to yeast nutrient, zinc sulfate was not found to improve the fermentation rate. In order to consider whether or not supplementing zinc can improve fermentation in homebrewing, more studies must be conducted with different factors taken into consideration such as the yeast variant, the juice used and the initial concentration of zinc compounds in the juice.}, language = {en} } @masterthesis{Schultner, type = {Bachelor Thesis}, author = {Schultner, Sarah}, title = {Vertrauen in K{\"u}nstliche Intelligenz am Beispiel des automatisierten Fahrens}, school = {Hochschule Rhein-Waal}, abstract = {Als ein Bereich der K{\"u}nstlichen Intelligenz erf{\"a}hrt automatisiertes Fahren immer mehr praktische Anwendung.

Inter-yarn frictional behavior is thoroughly analyzed to explore the effects of different frictional models and contact types, to produce a cost-effective process on the outcome of final composite product. For an efficient investigation, a meso-finite elemental analysis is performed by replicating picture frame test virtually in Abaqus/Explicit solver. Suitable contact formulation and multiple friction models are used to input the frictional parameters on meso scale model. Finally, the simulation results are then validated by comparing between corresponding contact algorithms and frictional models. Objective of this thesis: The main objective is to determine the mechanical properties, concentrating on effects of friction of a Twill pattern weave by performing virtual simulations by replicating picture frame test (PFT). Solution process: Adequate literature research is accomplished for better understanding of concepts of simulation. In material modeling, hypo elastic material is defined for material properties is imported through VUMAT. Multiple frictional models, including VFRIC and VFRICTION are added to the model to define frictional behavior. In-plane shear deformations are calculated by numerical simulations virtually in Abaqus/Explicit solver and then results are examined. Key Results: Satisfied simulation results are obtained as expected. The frictional behavior between yarns is sensitive to contact algorithms and friction models, and quality of material modeling. The shear locking phenomenon is captured beyond 55-degree shear angle and observed that regardless of value of coefficient of friction yarns, the type of frictional models influences simulation results and force values.}, language = {en} } @masterthesis{Klose, type = {Bachelor Thesis}, author = {Klose, Marian}, title = {Optimierung der Krebstherapie durch Inhibition von MDR1}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-4427}, school = {Hochschule Rhein-Waal}, pages = {86}, abstract = {MDR1 (Multidrug Resistance Protein 1) stellt ein Membranprotein dar, welches das Ziel hat, den K{\"o}rper vor Toxinen und Xenobiotika zu sch{\"u}tzen.

Even though the vaccine BCG exists for tuberculosis since the beginning of the 20thcen-tury, it lacks efficacy and does not provide sustainable protection. An important step to develop a long-term immunity is the expansion of antigen-specific T cells in the lymph node. For T-cell priming to occur, the pathogen and/or its antigen has to be transported from the site of infection to the T-cell zone of the draining lymph node. This step is done by migratory Dendritic cells (DCs). DCs reside as sentinels in tis-sue, where after pathogen encounter, internalize the pathogen, process its antigens and migrate to the draining lymph node. Using a modified protocol, developed by Bollampali et al. (2015), during a previous study done Dr. Rothfuchs team, we investigated the mechanisms involved in the migration of DCs after injection of BCG. For this we injected mice with different inhibitors and recep-tor antagonists. It is worth mentioning that in a yet unpublished previous work we in-hibited the enzymes COX-1 and COX-2 systemically, using indomethacin, and showed a decreased number of DCs migrating to the draining popliteal lymph node after BCG in-jection compared to mice not injected with the inhibitor. Following our experiment, we decided to investigate the receptors of one of the down-stream products of COX, PGE2 and the corresponding receptors EP2 and EP4. Based on other studies two of the four receptors of PGE2, EP2 and EP4, are important for the mi-gration of DCs. We then injected mice with antagonists for these two either separate or simultaneously. Even though their affinities and the sustainability of the reaction caus-ing PGE2signalling are different, both receptors were able to compensate for each other, but a decreased number of DCs were found in the lymph node when both antagonists were injected. This and the results of the COX inhibition suggest a role for PGE2 on DC migration. Based on these results we decided to look at MMP-9, a molecule regulated by PGE2 sig-nalling. However, inhibition of MMP-9 in our model did not impact on DC migration. It is unclear if treatment with the MMP-9 inhibitor used failed or if MMP-9 is indeed not important in BCG-triggered DC migration. In conclusion in this thesis we show a role for EP2 and EP4 on DC migration after BCG injection but failed to show the same for MMP-9.}, language = {de} } @techreport{Li, type = {Working Paper}, author = {Li, Jingyao}, title = {Die Unterschiede zwischen einem Sicherheitsbeauftragten und einer Fachkraft f{\"u}r Arbeitssicherheit hinsichtlich Ausbildung, T{\"a}tigkeit und Verantwortungsbereich}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-8771}, pages = {7}, abstract = {In diesem Arbeitspapier, das an der Fakult{\"a}t f{\"u}r Life Science der Hochschule Rhein-Waal (Prof. Dr. Kopetz) entstanden ist, werden die Unterschiede zwischen einem Sicherheitsbeauftragten und einer Fachkraft f{\"u}r Arbeitssicherheit hinsichtlich Ausbildung, T{\"a}tigkeit und Verantwortungsbereich er{\"o}rtert und mit genauen Quellenangaben der Rechtsgrundlagen versehen.}, language = {de} } @masterthesis{Nugroho, type = {Bachelor Thesis}, author = {Nugroho, David Limanhadi}, title = {The impact of light on the activity of PLP-dependent enzymes}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-8864}, school = {Hochschule Rhein-Waal}, pages = {95}, abstract = {Enzymes are important biological catalyst with high chemo-, regio-, and stereoselectivity. Among the different classes of enzymes, PLP-dependent enzymes are of special interest for industrial biocatalysis due to their wide range of applications. As it is known, that the cofactor PLP is instable under light exposure, the aim of this thesis was to investigate, whether this affects the activity of PLP-dependent enzymes. Therefore, six PLP-dependent enzymes consisting of four amine transaminases from Chromobacterium violaceum (Cv2025), Vibrio fluvialis (VfTA), Bacillus megaterium (BmTA), and an eleven rounds mutated Arthrobacter sp. (AsTAmut11) and two lysine decarboxylases from Escherichia coli (EcLDC) and Selenomonas ruminantium (SrLDC) were analyzed in different natural and artificial light setups. Cv2025, BmTA, and SrLDC have approximately 40\%, 30\%, and 50\% reduced activity in the light compared to dark condition respectively. EcLDC shows highest inactivation of about 90\%. VfTA is stable in HEPES buffer but has 50\% inactivation in TRIS and KPi buffer. AsTAmut11 is a special case, where there is no inactivation seen in light condition, but the enzyme gains about 30\% and more activity over the course of 6 h. This was seen in the dark and light condition. Conclusively, not only light itself effects the enzyme activity, but also the reaction conditions in combination with the light. The whole study proves, that it can be of immense importance to protect some PLP-dependent enzymes from light. Not only during the reaction, but also during the purification procedure. To mediate proper analysis of LDCs, a new photometric assay was developed using the indicator p� nitrophenol, in contrast to the available work intensive HPLC analysis. This indicator covers pH range from 6 to higher than 8 and enables sensitive analysis of cadaverine concentration with high sensitivity below 1 mM. With optimized photometric cadaverine calibration, the photometric assay is a reasonable alternative to HPLC based analysis.}, language = {en} } @masterthesis{Hoffmann, type = {Bachelor Thesis}, author = {Hoffmann, Annika}, title = {Pr{\"u}fung eines Anlagenreinigungsprozesses in der Kosmetikindustrie und vergleichende Analyse der Wirksamkeit der eingesetzten Reinigungsmittel und Desinfektionsmittel}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-5378}, school = {Hochschule Rhein-Waal}, pages = {103}, abstract = {Kosmetika haben einen hohen Stellenwert in unserer heutigen Gesellschaft und der pro Kopf Konsum der immer vielf{\"a}ltiger werdenden Produkte w{\"a}chst stetig an.

Vitamin companies should be aware of the commoditization phenomenon in order to stay competitive. By knowing the right strategy, vitamin producers can retain market share and still maintain profit in a commoditizing market. There is an increasing competition from the new entrants. Most of them are coming from Asian countries with the advantage of lower production cost. As a result, they oversupply the market with lower price products and change the product value proposition. They take incumbents' market share gradually, starting from the mass market. This thesis utilized qualitative approach to examine the problem. The author conducted interviews with representatives from BASF to provide internal perspectives, and BASF's customer to provide external perspective. In order to assess the countermeasure that has been done by other companies, comparative case studies was deployed. Vitamin C industry case study was used as a base to understand the commoditization in vitamin D3 industry. As a result, similar commoditization pattern can be seen in vitamin D3 industry. However, vitamin D3 industry is not commoditizing at the same pace as vitamin C industry due to different market size and complexity of production.

The gathering of information was done in three ways: 1) online research to gather basic information about the species, 2) communication with the Umweltbetriebe Kleve and the Niederrhein forestry office to obtain information about the situation in Cleve, Germany 3) visits to the different black locust stands to get an understanding of the situation. Black locust is a pioneer species with a short life span and is considered as an invasive neophyte in many European countries due to its strong suckering and ability to advance into habitats which then undergo an irreversible change in soil and species composition leading to biodiversity loss in especially threatened habitats such as dry grasslands. This is opposed by black locusts' strong biomass production, making it well suited for plantation production, resulting in a strong, durable and fast growing multiuse wood as well as nutritious foliage which can be used as animal fodder or for the production of bioenergy. The 9 visited black locust stands situated in and around Cleve, Germany are well established middle-aged stands not used for the production of high value wood. These stands were considered as not threatening to their adjacent environments due to their being surrounded by streets, waterbodies and well maintained fields and parks making a spread unlikely. As the stands are quite old already letting them fade out by natural succession would be the recommended management method. Should the need for removal present itself, girdling would be the suggested technique as, even though it is quite time intensive, it is the least forceful method and thus minimises the possibility of a strong suckering reaction. In conclusion it can be said, that its usage and management system strongly depend on the location and closeness to threatened habitats, considering that, the environmental aspect should always be put before the economic benefits.}, language = {en} } @misc{KC, type = {Master Thesis}, author = {K C, Manoj}, title = {Material uses of nut and other fruit shells}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-8755}, school = {Hochschule Rhein-Waal}, pages = {108}, abstract = {This review paper focused on the potential uses of nut and fruit shells. Based on the information from several kinds of literature, the composition of nut and fruit shells were studied, and the shells demonstrated the possibility to produce a wide range of materials such as bio-adsorbent like activated carbon; construction materials like concrete block, earth block, bricks, cement, etc.; and bio-composites like WPC, bio-plastic, etc. Besides these antimicrobials, drugs, insecticides, nanoparticles, and impact-resistant materials could be prepared from nut and fruit shells. Moreover, the production process for these materials was explained in the later part of the paper. Also, the yield, cost, and performance of materials prepared from nut and fruit shells were discussed and found that some of the products were as good as commercially available materials. The environmental impact being one of the important parts, materials from nut and fruit shells had a beneficial impact on nature. However, the entire life cycle assessment suggested that better techniques are required to attain a lower negative impact on the ecosystem. Since nut and fruit shells were the easy and low-cost raw material, they had a greater chance of replacing other expensive, non-environment-friendly raw materials and their products.

The aim of this study was to assess the effects that frass from black soldier fly reared on 3 different diets may cause when applied fresh and dried (70°C) on a sandy loam soil, in 2 application rates (0.2 and 2\% w/w). For that, frass was chemically characterized before a 28-days incubation, at the end of which samples were analysed from the chemical and biological point of view. It was found that thermal treatments and diets didn't vary significantly in microbiota stimulation, even though a chemical analysis would suggest the potential for enriched-frass from pig effluent and wheat bran to encourage microorganisms differently from beer \& coffee diet. Furthermore, fresh frass contrarily to what expected didn't contribute with living microorganisms to enhance microbial activity and growth. However, a difference was reported for the application rates, with the 2\% leading to more mineralisation than control. A trend for 2\% dried frass from B\&C was found, indicating the establishment of an efficient community of fungi slowly mineralizing recalcitrant and exhausted frass. Results indicate that more studies testing application rates ranging between 2 and 2.5\% have to be conducted.

Terrestrial ecosystem plays an essential part in the uptake of "greenhouse gases (GHGs) such as Nitrous oxide (N2O), Methane (CH4) and Carbon dioxide (CO2)" through photosynthetic sequestration of atmospheric CO2 released from fossil fuel emission, cement manufacturing and deforestation. Rhizodeposits is the released carbon from the root rhizosphere containing a large amount of carbon, essential nutrients and organic compounds. This process is known as rhizodeposition and is often quantified as carbon derived from rhizodeposition (CdfR). This thesis aims to review selected existing literature on above and below-ground biomass carbon (AGB-C and BGB-C) inputs which were used to quantify the carbon sequestration of rhizodeposits in the below-ground biomass (BGB) of different terrestrial ecosystem biomes in the world and to know where the carbon sequestration is lacking the most. Measurement of rhizodeposition in the soil is mostly carried out in the laboratory involving the use of tracing root-derived C by isotopic and non-isotopic techniques, but in this thesis, about 60 papers from different sources were reviewed, and data on above- and below-ground biomass carbon were collected to quantify the C rhizodeposition in the terrestrial ecosystem biomes. The carbon content of the dry weight biomass was estimated by multiplying the above-ground biomass (AGB) and below-ground biomass (BGB) by 0.45. The C-rhizodeposition from the BGB-C was calculated by multiplying the BGB-C by 0.5. Quantification of global C stored in the biomes, including arable crops, was quantified by multiplying the world land area of different biomes with average AGB-C and BGB-C. The estimated values of the mean, median and range of AGB-C, BGB-C and C-rhizodeposition of different biomes (tropical forest, boreal forest, temperate forest, temperate grassland, tropical grassland) and arable crops were reported in this paper. The global C-storage of above- and below-ground of different biomes and arable crops were also quantified. The values were 210, 116, 93, 7.4, 47.2 in Gt C for the tropical forest, boreal forest, temperate forest, temperate grassland, tropical grassland, and 2.4 Gt C for below-ground arable crops only.

However, this was not by accident, but a response to the requirements of the famers in this region. Those coops have been developed in the M{\"u}nsterland, a region north-west located in NRW which is famous for their intensive livestock-business and small amount of arable land, and in general is the home of small, structured family-farms. In the past, cooperatives have been the only one to provide information and products to the farmers in this region. Due to those circumstances the farmers in this region have a strong attachment to "their coops". As a result of this specialty several joint ventures of cooperatives have been observed.

Neben Vorteilen wie dem Wegfall der Anfahrt zum Arbeitsplatz und erh{\"o}hter Job-Autonomie stellt sich die Frage, ob Teleheimarbeit auch negative Konsequenzen mit sich bringt. Ziel der vorliegenden Arbeit ist es, zu untersuchen, wie Teleheimarbeit das Wohlbefinden von arbeitst{\"a}tigen Personen beeinflusst. Methodik - Auf Grundlage von Frageb{\"o}gen wurde eine Online-Befragung entwickelt. Teilnehmende waren Personen, welche seit Ausbruch des Corona-Virus in Deutschland arbeitst{\"a}tig waren (N = 200). Es wurden die Variablen Teleheimarbeit-Intensit{\"a}t, subjektive soziale Isolation, arbeitsbezogene Stressreaktion sowie die dem Work-Family Conflict zuzuordnenden Variablen Family Interference with Work und Work Interference with Family erhoben. Ergebnisse - Es wurde ein positiver Zusammenhang zwischen der Teleheimarbeit-Intensit{\"a}t und subjektiver sozialer Isolation, arbeitsbezogener Stressreaktion sowie Family Interference with Work gefunden. Es zeigte sich eine vollst{\"a}ndige Mediation durch subjektive soziale Isolation beim Einfluss der Teleheimarbeit-Intensit{\"a}t auf die arbeitsbezogene Stressreaktion.

The application of artificial intelligence is becoming popular in diverse domains, making its role in gas transport networks more and more interesting. The opposite interest of the players in the network is the reason behind the thought of establishing a game analogy here. The agents as players act on the basis of the opponent's action. Since both agents perform actions from different space, a neural network model is designed for the dispatcher agent to learn to make decisions for active elements based on its experience from the sample gas transport network. Behavior of the network and its elements is depicted using an optimized gas network simulator. The representation of the gas transport network and its state is digitally transformed so that it is able to extract the features by an artificial neural network representing the environment and its rules. With the help of the trained neural network, the dispatcher agent decides the control decisions with less accumulated penalties.

In this study, three main analytical techniques were used to comprehensively analyse the urban surface water quality. Luminescent bacteria test is a rapid and sensitive bioassay for acute toxicity determination in water. Through the inhibition rate of bacteria, the toxicity of water quality is reflected in a short-term. In this study, Vibrio fischeri bioassay was used to determine the toxicity in urban surface water. However, when the luminescence results of samples have only a slight difference, AAS and TOC can be used as sensitive chemical analytical techniques. atomic absorption spectroscopy (AAS) can analyse the heavy metal concentration and total organic carbon (TOC) can determine the organic contamination in water. AAS and TOC can quantitatively and qualitatively analyse chemical parameters. In the study, although each technique has a certain limitation, the combination of these three experiments can be detailed explain the cause of toxicity of urban surface water. Therefore, the advantage of these three methods which are fast, highly sensitive, and easy to operate, makes the analysis of water quality more efficiently. In this study, the water samples were analysed after filtration.

For this paper seven MRSW (Male Refugee Sex Workers) were interviewed. The collected data was evaluated by the method of qualitative content analysis and by taking various important analytical categories (motivations, identity, practice) supported by the existing literature, into consideration. The findings show that MRSW use sex work in diverse ways, in order to generate different kinds of profits: While raising economic capital served as the main motivation, cultural and social capitals were generated as well. Language skills, peer bonding, and being able to understand German culture served as the greatest outcomes of sex work. As the motive, we can see that financial instability drives MRSW to sex work, but that social media plays a huge role in making sex work appear as a efficient and feasible option.

Da in Deutschland ein Psychotherapieplatzmangel besteht werden in dieser Thesis die Fragen erörtert, (1) wie die ICBT als Innovation zu charakterisieren ist, (2) ob sie sich als kosteneffektive Behandlungsform f{\"u}r Menschen mit einer Depression eignet und (3) welche Zielgruppen davon abgesprochen werden könnten. Theoretischer Hintergrund: Bei der Depression handelt es sich um eine häufige und oftmals unzureichend behandelte psychische Erkrankung, was zu hohen Gesundheitskosten f{\"u}hrt. Die Digitalisierung des deutschen Gesundheitssystems ist noch nicht stark ausgeprägt, wird jedoch durch Gesetzgebungen und der Evaluation digitaler Behandlungsformen ausgebaut. Die ICBT basiert auf der kognitiven Verhaltenstherapie, welche bei Depressionen eine hohe Wirksamkeit zeigt. Durch die Erprobung der ICBT in anderen Ländern könnte diese eine wirksame Innovation f{\"u}r die deutsche psychiatrische Gesundheitsversorgung darstellen. Methodik: F{\"u}r die Beantwortung der Fragestellung wurde eine Literaturanalyse von ICBT- Behandlungen bei unipolaren Depressionen im Zeitraum von 2015-2020 in den Datenbanken Pubmed und Cochrane Library durchgef{\"u}hrt. 24 RCT-Studien und Metaanalysen entsprachen den Einschlusskriterien. Zur Analyse der Innovation wurden die in den Studien verwendeten ICBT-Programme als Innovation charakterisiert, mit Erfolgsfaktoren verglichen und die Wirksamkeit erhoben. Zudem wurde eine Kosten-Effektivitätsanalyse (KEA) durchgef{\"u}hrt. Ergebnisse: Bei der ICBT handelt es sich um eine Prozess- sowie marktmäßige Innovation f{\"u}r das deutsche Gesundheitswesen, welche sich als Basistechnologie etabliert hat. In der Wirksamkeitsanalyse konnten in 20 Studien eine Reduktion der depressiven Symptome erhoben werden. Die durchschnittliche Effektstärke der ICBT gegen{\"u}ber der Kontrollgruppe lag bei 0,34. Ein Problem stellte die geringere Adhärenz bei der ICBT-Behandlung dar. Bei der KEA stellte sich die ICBT-Behandlung im Vergleich zur Kontrollbedingung als kostenintensiver heraus. Diskussion: Die ICBT zeigt sich in den meisten Studien als gleichwertig zu einer Face-to- Face-Behandlung. Zur Steigerung der Adhärenz sollten geleitete ICBT-Programme bevorzugt werden. Die Erfolgsfaktoren sind teilweise erf{\"u}llt, jedoch sind diese abhängig von der Art der Implementierung im Gesundheitswesen. Die ICBT hat weiterhin das Potenzial, langfristig Behandlungskosten einzusparen. Zuletzt wurden Möglichkeiten aufgezeigt, welche eine Implementierung der ICBT im deutschen Gesundheitswesen erleichtern könnten. Ausblick: Bei der ICBT handelt es sich um eine wirksame Behandlungsform, welche f{\"u}r bestimmte Patienten im deutschen Gesundheitssystem geeignet sein kann.}, subject = {Depression}, language = {de} } @misc{Ghimire, type = {Master Thesis}, author = {Ghimire, Dikshant}, title = {Assessment of the Impact of lockdown on PM 2.5 emission in Nepal}, school = {Hochschule Rhein-Waal}, abstract = {Air pollution has been one of the main concerns for Nepal for a very long and PM2.5 is one of the most neglected air pollutants in Nepal. Nepal is among the countries most affected by both indoor and outdoor PM2.5 pollution in the world. This thesis is based on the recent lockdown that happened in Nepal during the pandemic of COVID-19 in 2020. This study investigates the impact of lockdown on PM2.5 emission based on the assessment of emission inventories. The annual data for PM2.5 emission was extracted from EDGAR (Emissions Database for Global Atmospheric Research) and then the extrapolation was done to calculate the assumed PM2.5 emission for 2019 and 2020 using linear regression. The assumed nationwide monthly emission ercentage was used to calculate the PM2.5 emission during lockdown months. The PM2.5 sources affected during the lockdown were identified and their assumed percentage contribution (6.18\%) was used to calculate the emission during lockdown month. The ambient air PM2.5 concentration data was extracted from the official websites of the government of Nepal. The lockdown months were compared with the preceding year's same month and the percentage change was calculated. The study suggested that in 2020 the PM2.5 emission rate for April was reduced by 4.68\% and for May it was reduced by 4.85\% whereas during an assumed 'no lockdown' year, all the months would have had an increase in PM2.5 emission by ~1.6\%. The concentration of PM2.5 for March was educed by 14.65\%, similarly, for April it was reduced by 13.96\% and for May it was reduced by 50.92\%. The comparison of the percentage change of both the PM2.5 emission and concentration shows that the decrease in concentration was much higher compared to the reduction in emission due to the lockdown. The monthly assessment of PM2.5 during the lockdown suggested that the percentage change in emission of PM2.5 was minor compared to the change in the concentration of PM2.5 which might be due to different reasons including meteorology, underestimation of the contribution of some emission sectors by the emission inventories and the fact that the emission inventories are set up for the whole country whereas the PM2.5 concentration data are collected with monitoring stations located in cities close to major PM2.5 sources.}, language = {en} } @masterthesis{Dai, type = {Bachelor Thesis}, author = {Dai, Chenke}, title = {Testing the Influence of Platinum Load on Performance of Fuel Cells Using Impedance Spectroscopy and Current Voltage Measurement}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-7730}, school = {Hochschule Rhein-Waal}, pages = {67}, abstract = {Increasing Platinum catalyst loading in proton exchange membrane fuel cell is supposed to increase the performance and lifetime. However, Platinum is an extremely expensive material. Therefore, increasing loading could contribute to the price significantly.

The tested cathodic loadings are 0.3 mg/cm2, 0.6 mg/cm2 and 0.9 mg/cm2. By applying two methods: current-voltage measurement and electrochemical impedance spectroscopy, the open circuit voltages, polarization, power output and impedance were recorded. From the experiment, it is found that the internal resistance decreased with increasing Platinum loadings on the cathode. The simulation results indicate this change is mostly contributed by decreasing cathodic resistance. With increasing cathodic Platinum loading, the cathodic resistance decreases. It is also found during experiments, the polarization, open circuit voltage and power performance first increased and then stayed at same level. These indicators showed best performance at 0.6 mg/cm2 cathodic loading level. Combined with simulation results, the large impedance value of constant phase element in equivalent model for 0.9 mg/cm2 loading is considered as the reason why the power performance stop improving.}, language = {en} } @masterthesis{Vaessen, type = {Bachelor Thesis}, author = {Vaeßen, Malte}, title = {Market analysis in the industry field of implantable medical devices}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-7844}, school = {Hochschule Rhein-Waal}, pages = {53}, abstract = {This thesis deals with the problem of missing research on market analysis in the specific healthcare market of implantable medical devices.

The loss i.e., the decrease of biodiversity, does not only have negative effects on vegetation and animals, but also on humans. If nature is doing well, people are doing well. In order to counteract the loss, this bachelor thesis attempts to increase plant and insect biodiversity at a specific location with insect-friendly seed mixtures and by measuring the change using comparison areas. Accordingly, the two research questions were addressed: (1) "How does plant-biodiversity change in the backyard and front yard on the seed mixture plot compared to plant-biodiversity in the backyard and front yard next to the seed mixture plot?" and (2) "How does insect-biodiversity change in the backyard and front yard on the seed mixture plot compared to insect-biodiversity in the backyard and front yard next to the seed mixture plot?" To answer these research questions and to obtain more suitable data, a wildflower strip was established in the backyard and one in the front yard, each with an adjacent reference field, to ensure equal environmental conditions and to detect changes in flora and fauna. Plants and insects were observed and documented during the flowering period in order to determine differences in biodiversity sizes afterwards. The comparison of the different biodiversity sizes shows that an increase in insect and plant biodiversity can be achieved by planting insect-friendly wildflower strips. As the increase of plant biodiversity also leads to the increase of insect biodiversity. Further research in the field of biodiversity enhancement could be done by collecting more measurement points of the coefficients at additional locations to extend the data set and to improve the applied method of this bachelor thesis.

Consequently, the conditions for clubs have also changed. Today it is not only important to be successful in sports, but also to do business in a solid and sustainable way. Nevertheless, many clubs are still not able to do so. This is due on the one hand to a lack of experience and deficits in the management and control systems and on the other hand to the mindset to buy sporting success by all means. This frequently leads to clubs operating beyond their means and regularly posting high losses. Sustainable investments and future growth are often disregarded. That is why UEFA decided to introduce the Financial Fair play regulations in the year 2013. The rule is in place to avoid debt and to ensure healthy business operations over the long term.

This requires applications of sophisticated lipid separation methods. The purpose of this work was the development of an ESI-MS/MS method for the quantification of acylcarnitines with high specificity and reliability for the identification of low abundant acylcarnitine species in complex samples. General aspects of acylcarnitine analysis, including several types of solid-phase extraction, and derivatization with liquid extraction were investigated using commercially available acylcarnitine standards. The established experimental workflows, including an optimized cation-exchange extraction and derivatization with liquid extraction, were successfully applied to quantify acylcarnitine species in samples of biological origin. Consequently, murine brain tissue samples were quantitatively analyzed using two extraction procedures.

Some of the properties include affinity, solubility, organic solvent resistance, enantioselectivity and thermostability. The probability of succeeding in directed evolution experiment depends on the size of the library generated, because the more variants are present, the higher the chances of detecting an enzyme with improved properties. The throughput represents the main bottleneck in enzyme screening, as most of the methods allow the analysis of 104 variants per round, which is not enough for a library size of 109 variants. Ultra high-throughput screening (uHTS) enables the analysis of 107 events per hour. It can reduce the time, costs and consumables needed for an applied round of directed evolution. One of its limitations is the use of a flow cytometer, which is expensive and not affordable for everyone. Also uHTS is restricted to single catalytic reactions and their coupling with synthetic fluorophores. The objective of this project is to develop an uHTS method based on fluorescence activated cell sorting (FACS). The principle of this method is to sort cells expressing the active enzyme variant, which have a fluorescent hydrogel formed on the cell membrane. Successful completion of this protocol will allow the screening of different enzyme classes, for example, laccases, alcohol dehydrogenases, organophosphorus hydrolases. In order to prove that the concept is working, laccase will be used for generating the library, which will then be displayed on the surface of E. coli. The variants which are enzymatically active, will produce the radicals that initiate the polymerization reaction of fluorescent hydrogel, allowing the flow cytometer to sort cells based on the fluorescence emitted. One round of sorting should achieve at least a 3-fold enrichment of the active enzyme population.}, language = {en} } @misc{OPUS4-777, title = {19/2021 Erneute Verschiebung der Wahlen zu den Gremien der Studierendenschaft der Hochschule Rhein-Waal}, volume = {2021}, number = {19}, organization = {Hochschule Rhein-Waal}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-7775}, pages = {3}, language = {de} } @misc{OPUS4-776, title = {18/2021 Erneute Verschiebung der Wahlen zu Gremien und Organen der Hochschule Rhein-Waal aufgrund der weiterhin ausstehenden BSI-Sicherheits-Rezertifizierung der POLYAS GmbH und Festsetzung des Wahltermins}, volume = {2021}, number = {18}, organization = {Hochschule Rhein-Waal}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-7760}, pages = {2}, language = {de} } @misc{OPUS4-770, title = {17/2021 Erste {\"A}nderungssatzung zur Zugangsordnung f{\"u}r die Masterstudieng{\"a}nge Mechanical Engineering und Bionics der Fakult{\"a}t Technologie und Bionik an der Hochschule Rhein-Waal}, volume = {2021}, number = {17}, organization = {Hochschule Rhein-Waal}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-7702}, pages = {6}, language = {de} } @misc{ChetamunAmraouzaHuseynlietal., author = {Chetamun, Ishwaree-Devi and Amraouza, Asmaa and Huseynli, Ilkay and Rizvi, Syed-Muhammad-Mujtaba-Hussain}, title = {WATER-IT Smart Sprinkler}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-7694}, pages = {3}, abstract = {Although smart irrigation systems are being extensively used for several years now, little effort have been dedicated towards sprinklers with wind compensation, resulting in many sprinklers in the market having less optimal design. Thus, this project aims to improve the existing sprinklers by including wind compensation. To reduce the effect of wind on the irrigation pattern, the sprinkler velocity and radius of throw need to be adapted to the wind's velocity and direction. Our control valve box contains seven major components. Wind and rain sensors that will collect the weather conditions, an LCD where irrigation time will be displayed, additionally to a microcontroller communicating with a second MC at the sprinkler head box via Bluetooth and controlling an electrically actuated ball valve and solenoids connected to inline pressure reducers. These three latter components play an important role in supplying proper water conditions for the sprinkler by adjusting the pressure and water flow. The position of our sprinkler's nozzle will be detected with a magnetometer and compared to wind direction. The servo motor will rotate the sprinkler and this latter will start irrigating in a 180° pattern for couple of minutes before rechecking again all the conditions. When the sprinkler nozzle is facing the wind the velocity of throw will be increased, and after it is rotated and is in the same direction as wind, the velocity of throw will be reduced, because wind is already assisting the water droplet reach its radius. If the wind velocity is larger than the threshold value, or if it is raining, the system will not start although the switch is turned on.

The pole can be placed anywhere in the garden as long as the portable sprinkler stays within a range of 100m. When switched on, the controller on the sprinkler gets continuously updated with the current wind speed and direction using wireless transceivers. The sprinkler can also be controlled through an app on a smartphone. Simple commands such as ON/OFF switch, as well as timers for autonomous watering are possible to set up. For example, setting up the system to water the garden at sunrise, which has been suggested by experts as the most effective time to irrigate plants.

Thus, we conducted quantitative microlevel studies in low-lying communities in two high-mobility countries - Ghana and Indonesia - that are particularly exposed to coastal hazards like erosion, land subsidence, storm surges and an increasing sea level, and are prone to flooding on a regular basis. Different measures of environmental threats were collected, ranging from individual perceptions over the household's distance to the coast to expert opinions. We analyzed the relationships using logistic regressions and controlled for contextual factors on multiple levels. No statistically significant direct impacts of slow-onset environmental events on migration decisions could be detected. Perceptions of storms, a clearly sudden-onset event, however, were found to be significantly linked to out-migration decisions in Ghana.

Lockdown has prohibited people to go outside of their houses, closed industries and factories, and restricted air transportation and the free movement of vehicles, except emergency vehicles and flights. On the optimistic side, improvements in ambient air quality due to the lockdown have been reported across the world. This study evaluated ambient air quality by analyzing the PM2.5 concentrations monitored in 7 major cities of Nepal during March, April, and May of the years 2019 and 2020. Furthermore, meteorological data were also evaluated to investigate how meteorological conditions have affected Nepal's ambient air quality during the investigation period. The monthly mean PM2.5 concentrations during March, April, and May 2020 were found to be lower in nearly all of the 7 cities of Nepal as compared to March, April, and May 2019. To some extent, a slightly higher amount of precipitation in March-May 2020 than during March-May 2019 supressed the ambient PM2.5 concentrations in 2020. But, since the highest decrease in PM2.5 concentration was found in Nepalgunj (72.78\%) followed by Kathmandu (46.2\%) during May 2020 as compared to May 2019 and thus, the highest differences between 2019 and 2020 were found for the cities with the highest contribution of transport emissions to PM2.5 in ambient air, the COVID-19 lockdown might have contributed to the lower PM2.5 concentrations in 2020. On the other hand, it can be assumed that one of the major primary sources of PM2.5, biomass burning (both the residential use and natural forest fires), was not affected by the lockdown, but biomass burning might be the reason for the increment of PM2.5 concentrations found at some sites, in particular in the Kathmandu Valley, and for the only subtle decrease at other sites during the lockdown. In essense, though it is an unfortunate situation, the lockdown provided a glimpse of the situation how effective improvements in the environmental conditions could be if we were to introduce large scale mitigation measures swiftly.

This quote sums up most of the current thoughts on the phenomenon of a ground-breaking invention from 2008 by Satoshi Nakamoto since a major part of the world's population is still missing out on sophisticated knowledge about it. Especially in times of digitalization, it is of enormous value to be informed about current developments in technology. This thesis aims to evaluate the future development of money, especially if Bitcoin has the potential to totally replace conventional currencies. Furthermore, the strengths and shortcomings of Bitcoin will be discussed. It also reaches to determine characteristics for a currency's long-term success and which of those characteristics are fulfilled by Bitcoin. To answer the research question if Bitcoin has the potential to be an alternative currency and to test the developed hypotheses, pertinent literature is reviewed and an empirical study consisting of expert interviews which are examined using a qualitative structured content analysis method, are conducted. Afterwards, the results are critically discussed. The results of this thesis reveal that Bitcoin has the potential to become an alternative currency because it fulfills most of the criteria a currency needs to meet to be successful in the long run. Furthermore, it is evident that Bitcoin still faces vast barriers and needs to overcome enormous obstacles, which shifts the time horizon for becoming a success somewhere in the farther future. Additionally, apart from the development of cryptocurrencies, it is shown that money in general, will flow much more digitally in the short run. Besides that, this thesis offers insights about the promising future of Bitcoin's underlying core technology, the Blockchain, in various fields of application.}, language = {en} } @masterthesis{Giebel, type = {Bachelor Thesis}, author = {Giebel, Alice}, title = {Cloning Of Human Secretory Gelsolin In Pichia Pastoris}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-6585}, school = {Hochschule Rhein-Waal}, pages = {74}, abstract = {The production of recombinant proteins plays an important part in biotechnology for over 30 years. Their applications range from pharmaceutical practice up to industrial (non-medical) purposes and, therefore, show great importance in today´s life. Most recombinant proteins are being produced by genetic modification of microorganisms to either generate those intracellularly or to secrete the desired protein into their surroundings. Dependent of the expression mechanism, the production can be influenced and improved to achieve high yields and protein purity. One aim of this study was to determine and optimise the most favorable cloning strategy for the expression and secretion of the plasma form of the actin binding protein gelsolin from Pichia pastoris. Gelsolin has two isoforms of which one of them gained particular attention due to its application in research projects concerning the current COVID-19 pandemic. For this project, a variety of oligonucleotide primers were designed to amplify the whole sequences and various parts of both gelsolin isoforms during PCR approaches. The accuracy and efficacy of primers is determined by several factors such as their length and exact structure. Also, many factors depending on the sequence of interest are influencing the outcome of the PCR. Therefore, the second aim of this study was to design and validate primer pairs with most preferable conditions to amplify the sequence for the expression of gelsolin and optimise the PCR conditions for this purpose.}, language = {en} }
