The purpose of this paper is to analyze a presentation of eddy current sensing coils for the turbo charger speed measurement, which were manufactured with the low temperature co-fired ceramic (LTCC) technology. The goal is to be able to manufacture small robust coils with complex geometries and improved signal output.

A crucial element for its performance is the quality factor of the embedded coil. Thanks to the use of the developed LTCC manufacturing processes, the lateral wounding distance of the printed coils can be reduced to 30 µm, and simultaneously, the aspect ratio should be enlarged compared to standard LTCC technologies. By the use of a novel printed double-D coil design, the overall sensor characteristics will be improved.

The metallization thickness can be simultaneously enhanced that results in the internal resistance being reduced. Thus, the inductivity and the ohmic resistance achieve an obvious optimization that results in significant improvement of the quality factor of the novel coils when compared to standard technologies. Embedded micro coils have a sintered metallization aspect ratio of more than one and thus an optimal performance differing clearly from prior art. Their reliability was proven through temperature cycle tests of over more than 1,300 h.

The developed LTCC coil technology will be introduced in the JAQUET sensor portfolio of TE Connectivity for the measurement of turbocharger speed on both passenger cars and trucks. The measurement and control of turbochargers speed enables the optimal regulation of airflow into the engine thereby improving the fuel economy and leading to a reduction of engine emissions.

This paper shows fabrication and performance of the original manufactured LTCC coil for turbocharger speed sensors and its optimized signal output by the novel design.

Nearly 45 years ago, the Combahee River Collective, a group of Black feminists, released their statement, which served as a call to action to address gaps in contemporary Black feminism by engaging in antiracist and antisexist identity politics. In 1983, Jacqueline Fleming explored the making of matriarchs at historically Black colleges and universities (HBCUs) and predominantly white institutions (PWIs). Since then, there have been few explorations into the construction of Black womanhood at HBCUs (Njoku, 2017). Educational research across contexts that explores the construction of gender among African-American women has also been limited. This demonstrates a need to speak truth to power, challenging existing power structures throughout the academy. The inadequacy of educational narratives from Sistas at HBCUs, and across all institutional contexts, has yielded a single story of resilience that is used to validate the need for research on Black men, yet ignore Black women. As we look upon the survival of HBCUs beyond 2020, we must reconsider the ways that HBCUs contribute to the idea of identity politics and the existing challenges to these identity politics within HBCUs. In this chapter, we argue the importance for HBCU leaders to engage the Combahee River Collective's call by intentionally investing in Black women and amplifying narratives that give depth and debunk the myths and ignorance of Black women's college experiences. Truth-telling in this case harnesses the voices of African-American women at HBCUs “in the specific goal of confronting existing power relations”. We provide an updated response to the Combahee River Collective Statement in which we delve into the ways HBCUs contribute to identity politics and the challenges to identity politics at HBCUs. This chapter challenges power relations not only within the context that the narratives occurred but also within an academy that has failed to excavate them, until now.

The purpose of this study is to examine both the technical feasibility and the commercial viability of several demand-side integration (DSI) programs to utilize the charging flexibility of electric transport vehicles in a logistic facility. DSI is important for improving system reliability and assisting in integrating renewables into the energy system.

A pre-assessment of several DSI programs is performed by considering effort for implementation, costs and economic potential. Afterward, the most promising programs are compared economically on the basis of optimization methods and economic analysis. The analysis is based on a comprehensive electric mobility project dealing with electric transport vehicles operating in container terminals.

The pre-assessment of several potential DSI programs revealed that many of these programs are unsuitable, largely due to regulatory requirements. Although using DSI to optimize the company’s load is feasible, controlled charging based on variable prices is particularly advantageous because the implementation requires modest effort while identifying significant cost-saving potentials.

Based on the analysis, other companies using electric transport vehicles have a foundation for identifying the most promising demand-side management program.

While most research has focused on individually used electric vehicles, here commercial electric transport vehicles operating in closed systems were investigated as this area of application was found to be particularly suitable for participation in DSI programs.

The study investigated the contributions of household farming in palliating the economic effect of COVID-19 during the lockdown period. The study was questionnaire-based involving 510 participants randomly drawn from 17 Local Government Areas in Enugu State. Data were collected on demographic data, household expenditure, farm plots size, crops cultivated, sufficiency and extent farm produce contributed to palliating the effect of COVID-19 shocks. Data analysis used descriptive statistics, PCA and ANOVA. 89% households were fully involved in farming during the lockdown which positively impacted on household economy and especially SDGs 2 and 12. The lockdown improved household food production and pushed towards a positive behavioral change towards food security. 85% households indicated interest in expanding their farm size after the pandemic. Land and capital unavailability were significant barriers to taking farming as a major occupation. Several policy options were proposed to improve food production at household levels to mitigate the impact of COVID-19 crisis on food security.

This paper aims to present a conceptual framework for the emerging field of green energy platform economics.

The authors develop a conceptual framework based on a careful review of the existing literature, and research into the current provider landscape and insights from academic and industry experts. The authors also examine the implications for the energy sector’s value chain and derive a research agenda based on those areas where research still needs to be pursued.

The framework combines the spatial characteristics of platform models (residential/mobile) with the different types of platform business model (B2C/C2C/C2Grid). Using this framework, the authors illustrate how green energy platforms can fundamentally disrupt the conventional electricity value chain by enabling prosumers to market their assets, creating new arenas for trading and collaboration, and by increasing transparency and competition in the sector. The authors also identify areas where more research is required, particularly empirical studies into energy forms other than electricity and analyses of currently underrepresented aspects such as user interfaces and social interactions.

Green energy platforms have the potential to contribute meaningfully to the energy sector’s decarbonization, digitalization and decentralization, and hence to the deceleration of climate change.

This paper is among the first to provide a holistic perspective on platformization in the energy sector. It also offers a new perspective on platform economics in general that is based on the unique characteristics of energy as an economic good (intangibility, homogeneity, credence good).

This paper aims to present a requirements analysis for the processing of water-based electrode dispersions in inkjet printing.

A detailed examination of the components and the associated properties of the electrode dispersions has been carried out. The requirements of the printing process and the resulting performance characteristics of the electrode dispersions were analyzed in a top–down approach. The product and process side were compared, and the target specifications of the dispersion components were derived.

Target ranges have been identified for the main component properties, balancing the partly conflicting goals between the product and the process requirements.

The findings are expected to assist with the formulation of electrode dispersions as printing inks.

Little knowledge is available regarding the particular requirements arising from the systematic qualification of aqueous electrode dispersions for inkjet printing. This paper addresses these requirements, covering both product and process specifications.

The tourism multiplier effect (TME) is the total economic impact of tourism demand, representing the linkages between tourism and other businesses in an area. However, study about it is limited in Indonesia, especially at the provincial level and after the COVID-19 crisis. This study aims to estimate the TME in all provinces of Indonesia, test its differences in priority and non-priority areas before and after the COVID-19 crisis, analyze its spatial distribution and examine the determinant factor of TME

This study applies an input-output model to measure the TME of all provinces in Indonesia, an independent sample t-test to examine the similarity of TME in priority and nonpriority areas, a paired sample t-test to examine the similarity of it before and after the COVID-19 crisis, and spatial analysis to check its spatial relationship.

The result shows that regional TME ranges from 1.25 to 2.05 in 2019, which changed slightly over time. The empirical result shows the TME difference before and after the COVID-19 crisis, and there is a spatial correlation in terms of TME with the hot spots are clustered in the eastern region of Indonesia, However, there was a slight change in the position of hot spots during the COVID-19 crisis. Moreover, the spatial model shows that value-added and employment in agriculture, manufacturing, trade and transportation affect the size of TME.

This study contributes to the academic literature by providing the first estimate of the TME at the provincial level in Indonesia, comparing the it in priority and non-priority areas before and after the COVID-19 crisis, and mapping its spatial distribution.

Ethiopia suffers from structural food insecurity due to its low food production, low purchasing power, and climatic shocks such as drought. Coffee is Ethiopia's primary source of foreign earnings, and 95% of it is produced by smallholder farmers. Coffee also provide better income to smallholder farmers than other crops. However, it is unclear how much smallholder coffee producers participate in cash savings and if their savings help them attain food security. In this study, the authors aim to assess the impact of cash savings on the food security of smallholder coffee farmers in Ethiopia.

Using cross-sectional quantitative data from 336 randomly selected households and qualitative data from the local community, this study examines the impact of cash savings on household food security. Logistic regression and propensity score matching models were used to analyze the impact of cash savings on households' food security.

About, 43.5% of coffee farmers did not participate in cash savings during the study period, while 50.6% had no access to credit. The major factors that limit households' likelihood of participating in cash saving were the gender of household head and family size. Approximately, 38.4 and 27.1% of coffee farmers were food poor based on calorie intake and consumption scores, respectively. Households' participation in saving increases their ability to meet dietary energy requirements and consume diverse foods.

To the knowledge of the author, empirical studies that examined the impact of cash saving on the food security status of smallholder farmers in the study area are limited. Therefore, this study brings original contribution and fills research gap on coffee farmers' cash saving and food security; that received little attention from previous researchers in Ethiopia.

This study aims to investigate the relationship between dietary polyamine levels, metabolic risk parameters and anthropometric measurements in postmenopausal women.

This cross-sectional study was conducted with 562 45–64-year-old postmenopausal women who presented to a Family Health Center. To collect the data, the Descriptive Information Form and Food Frequency Questionnaire were used. In the data analysis, numbers, percentages, mean, standard deviation and multiple linear regression analysis were used.

The multiple linear regression analysis demonstrated that dietary putrescine intake was negatively associated with systolic blood pressure (ß = −0.179, p < 0.001), dietary spermidine intake was positively associated with waist circumference (WC) (ß = 0.142, p = 0.013), systolic blood pressure (ß = 0.188, p = 0.001), diastolic blood pressure (ß = 0.218, p < 0.001), body mass index (BMI) (ß = 0.169, p = 0.003) and waist-to-height ratio (WHtR) (ß = 0.156, p = 0.006), and dietary spermine intake was negatively associated with WC (ß = −0.158, p = 0.003), systolic blood pressure (ß = −0.195, p < 0.001), BMI (ß = −0.107, p = 0.042) and WHtR (ß = −0.138, p = 0.009).

Owing to the study’s cross-sectional nature, the lack of succession in the cause–effect relationship, the use of self-report Food Frequency Questionnaire to determine dietary polyamine intake and the inability to analyze seasonal differences are among the limitations of the study.

In this study, an association was determined between dietary polyamines, metabolic risk parameters and anthropometric measurements. The findings suggest that dietary polyamines in human health should be further investigated owing to the increasing metabolic risk parameters.
