title: Chemical compatibility of various working fluids with additively manufactured materials for two-phase thermal control systems

description: The chemical compatibility of materials is a critical aspect in the design, manufacture and heat transfer performance of two-phase thermal management systems. Long lifetimes can only be ensured by selecting container materials which are compatible with their working fluid. With the recent emergence of additive manufacturing (AM), which has shown significant potential for the design of next generation thermal control devices, chemical compatibility between AM alloys and different working fluids must first be determined however before they can be successfully deployed.

In this study, 30 different fluid-metal combinations were selected for experimental characterisation. Working fluids with high heat transport capacity such as water, acetone, methanol, toluene and ethylene glycol were included, as well as ammonia and propylene, which are particularly relevant for spacecraft applications. Selected AM materials comprised a range of widely available metal alloys, including AlSi7Mg, AlSi10Mg, Invar, 316L stainless steel and Ti6Al4V. Thermosyphon devices were manufactured for experimental life-testing using the Gas Plug Test. This involves setting isothermal conditions at the evaporators of the devices and monitoring the temperature profiles over an extended period of time. Any corrosion or chemical reactions result in the generation of non-condensable gas (NCG) and a corresponding reduction in condenser temperature.

At the end of 9000 hours of testing, the majority of fluid-metal combinations demonstrated excellent chemical compatibility, with a number of notable exceptions. For the case of Invar-methanol, fluid decomposition took place with the metal acting as a catalyst for the reaction. Galvanic corrosion occurred at the interface between the bimetallic combination of aluminium and stainless steel with toluene as the electrolyte. Regardless of the metal used, ethylene glycol was found to undergo rapid decomposition at temperatures greater than 150 °C, leading to device failure. Results for water showed slow continuous NCG generation for the duration of testing. These findings provide important information to designers and engineers who wish to make use of the benefits of AM in the next generation of two-phase thermal control systems.

title: Measurement system analysis for peristaltic-motion-frequency

description: This dataset is about the measurement system analysis of a new potential ecotoxicological end-point, the peristaltic motion frequency. During the measurement of the peristaltic motion frequency, the appraiser examines the rapid response of the xenobiotics in the environment to obtain information on the repellent effect and potential risk of annelids’ active mitigation. 
First, the preliminary experiments were carried out to check the feasibility of the measurement system. OECD model soils and CuSO4 reference solution were putted into test vessels. The soil samples were spiked with 0, 24, 48, 60, 96, 120, 240, and 2400 mg CuSO4/kg soil. Four vessels were used for the control samples, three for the other concentration levels and five animals were placed on the soil samples in each vessel. Based on the exclusion criteria 11 individuals should be removed from the test resulting in a total of 114 observations (instead of 125). One single appraiser has made the experiments. 
to assess the reproducibility variance, measurements were made by three appraisers at 0, 24, 48, 96, 120 and 240 mg CuSO4/kg soil concentrations. Five vessels were used for the 0 mg/kg concentration level but only the 2nd, 3rd and 5th were evaluated because the animals in the 1st and 4th vessels were not observed at the same time. Three vessels were used for the 24-96 mg/kg concentration, and four vessels were used for the 120 and 240 mg/kg concentration levels. The appraisers performed the measurements in parallel. It should be noted that the preliminary test results are not included in these experiments. Due to the exclusion criteria 270 observations were evaluated (instead of 300).
Extending the analysis by day-to-day variability, the reproducibility measurements underwent replication with a three-week interval. Thus, the arrangement of the experiments is approximately the same as in the case mentioned above: 0, 24, 48, 96 and 120 mg CuSO4 /kg soil samples were investigated, and on each level, 5-5 animals in 4-4 vessels were located. The three appraisers were the same three persons as in the first 3-appraiser's experiments.

title: Debt Servicing and Foreign Exchange Rate Unification

description: This study examined the relationship between debt servicing and foreign exchange rate unification in Nigeria from 1995 to 2023, hypothesizing that a unified exchange rate policy would significantly impact the country's debt service-to-revenue ratio. Using annual time series data from sources such as the International Monetary Fund and World Development Indicators, the study employed an Autoregressive Distributed Lag (ARDL) model to analyze the relationship between the debt service-to-revenue ratio and factors including the official foreign exchange rate, GDP growth rate, inflation rate, and oil prices.
The findings revealed several notable insights. Exchange rate unification was found to have a significant negative effect on the debt service-to-revenue ratio, suggesting that a unified exchange rate policy could help reduce Nigeria's debt service burden. Both current and lagged inflation rates showed a significant negative impact on the debt service-to-revenue ratio, indicating that higher inflation might be eroding the real value of debt or increasing nominal revenues faster than debt servicing costs. Lagged exchange rates were found to negatively affect the debt service-to-revenue ratio, implying that higher exchange rates in the previous period decrease the current ratio. Oil prices demonstrated mixed effects, with current prices positively impacting the debt service-to-revenue ratio while lagged prices had a negative effect. The study also revealed strong persistence in debt servicing behavior over time, as evidenced by the significant positive correlation between current and previous year's debt service ratios.
These results offer significant implications for policymakers. The negative effect of exchange rate unification on the debt service-to-revenue ratio suggests that such a policy could improve efficiency in forex markets and reduce arbitrage opportunities, ultimately helping to reduce the debt service burden. The negative relationship between inflation and the debt service-to-revenue ratio indicates that higher inflation might be beneficial for debt servicing in the short term, though this should be interpreted cautiously given the potential negative consequences of high inflation. The mixed impact of oil prices reflects the complexity of Nigeria's oil-dependent economy, highlighting the need for economic diversification. The strong persistence in debt servicing commitments points to potential structural issues in debt management or lack of fiscal flexibility.
Policymakers can use these findings to inform strategies for managing Nigeria's debt burden. The results suggest that pursuing exchange rate unification, carefully managing inflation, diversifying the economy to reduce oil dependence, and improving fiscal discipline could all contribute to better management of debt servicing costs. However, it's crucial to consider the lagged effects of economic variables on debt servicing when formulating long-term fiscal strategies.

title: Why Entrepreneurship Education for Students Does Not Guarantee the Sustainability of Their Business?

description: The results and discussion of this bibliometric study shed light on the complex relationship between entrepreneurship education and the long-term sustainability of graduate-led businesses. The thematic map and word frequency analysis reveal a strong emphasis on sustainable development, student-centered learning, and the cultivation of entrepreneurial skills within the context of higher education. However, despite the growing prevalence of entrepreneurship education in college curricula, many graduates still struggle to maintain their businesses over time. The disconnect between classroom learning and real-world challenges, insufficient post-graduation support and resources, and challenging market conditions all contribute to the high failure rates of these ventures. To bridge this gap, entrepreneurship education must evolve to incorporate more experiential learning opportunities, foster supportive ecosystems for graduate entrepreneurs, and equip students with the resilience and adaptability needed to navigate the complexities of the business world. The findings of this research have important implications for educators, policymakers, and aspiring entrepreneurs. By understanding the factors that influence the sustainability of graduate-led businesses, stakeholders can work together to develop more effective educational approaches, support systems, and policies that enable these ventures to thrive. Future research could explore the specific design elements of entrepreneurship programs that best prepare students for real-world challenges, investigate the long-term impact of post-graduation support initiatives, and examine strategies for fostering resilience and adaptability among graduate entrepreneurs in the face of market uncertainties.
