Effects of Curie particle induced accelerated curing on thermo mechanical performance of 2K structural adhesives – Part I: Bulk properties

ABSTRACT Adhesive bonding represents a widely established manufacturing process, which offers many advantages such as joining of different materials while resulting in a more advantageous stress distribution when loaded. Compared to other, mainly mechanical, joining techniques, the long curing times of adhesives – sometimes up to days – represent a decisive disadvantage. After adhesive application, contractors have to maintain these times until components can be moved for further processing, or full load can be applied. Different methods are used to circumvent the problem of adhesive cure, and thus accelerate polymerisation, among others, microwave, UV or conventional oven curing. In addition to aforementioned methods, the use of electromagnetic induction represents a promising non-contact method for accelerated curing. With this method, bonded components are exposed to a high frequency (HF) electromagnetic field (EMF), which generates heat that is transmitted to the adhesives to be cured, and in turn speeds up polymerisation. If adherends, like for example wood, glass, or G-FRP, are not sensitive to EMF, so-called susceptors (e.g. meshes, fibres or particles) are introduced into the adhesives, which can be heated inductively. Curie particles (CP) represent a special type of susceptors, which can only be inductively heated up to their material specific Curie temperature (T c) above which heating automatically stops. Thus, a curing process is designed, which is independent from external temperature monitoring techniques and – at the same time – prevents the adhesives from overheating. The present study investigated the influences of inductive curing with CP on the bulk properties of a 2 K epoxy resin and a 2 K polyurethane using standardised specimen types: adhesive bulk (AB) and dynamic mechanical analysis (DMA) specimens. The authors showed with an experimental programme of 92 specimens that resulting thermo-mechanical bulk properties of the two investigated adhesives are fundamentally changed by application of the process.
Upshots of Intrinsic Traits on Social Entrepreneurship Intentions among Young Business Graduates: An Investigation through Moderated-Mediation Model

Social entrepreneurship has recently become a much-desired area of research for academia, practices, and policymaking. Natural or cognitive personal thoughtfulness like loving-kindness meditation (LKM) and compassion trigger individual intentions towards the social entrepreneurial venture. In this process of individual social entrepreneurial intention personality trait plays a very vital role, such as entrepreneurship resilience. For this study, a purposive sampling technique was incorporated and data was collected from 631 business and management sciences students. Data is analyzed by SPSS 23 and for the hypothesis testing, we used the bootstrap analysis of Hayes PROCESS v3.5. This study depicts that LKM has a positive significant impact on compassion and no significant impact on social entrepreneurship intentions while resilience strengthens the direct relationship of compassion with social entrepreneurship and the indirect relationship of LKM with social entrepreneurship via compassion. This study contributes to solving the economic and social problems over the globe especially by boosting the LKM and resilience traits so that the young graduate commence social entrepreneurship. This study helps the academician and policymakers to adopt strategies through which they can encourage youth to indulge in social entrepreneurial ventures solve the social problem and decrease unemployment.
How does knowledge seeking and knowledge generation promote green supply chain management? An empirical study from China

ABSTRACT Acquiring and using knowledge resources is essential for companies to implement green supply chain management. It can help companies understand market information, government policies, and customer needs, as well as help companies carry out technological innovation and product design and development to maintain their competitive advantages. This research develops a conceptual model based on the knowledge-based theory, as well as the mediating effect of green self-efficacy and the moderating effect of knowledge application. The research hypotheses are verified using data from 264 companies in 8 industries in central China. The results show that knowledge seeking and knowledge generation can prompt enterprises to implement green supply chain management (GSCM). Green self-efficacy plays a mediating role between knowledge seeking, knowledge generation and green supply chain management. Knowledge application has played a positive role in regulating the relationship between knowledge seeking and green self-efficacy, and between knowledge generation and green self-efficacy.
Simulating observed cloud transitions in the northeast Pacific during CSET

The goal of this study is to challenge a large eddy simulation model with a range of observations from a modern field campaign and to develop case studies useful to other modelers. The 2015 Cloud System Evolution in the Trades (CSET) field campaign provided a wealth of in situ and remote sensing observations of subtropical cloud transitions in the summertime Northeast Pacific. Two Lagrangian case studies based on these observations are used to validate the thermodynamic, radiative and microphysical properties of large eddy simulations (LES) of the stratocumulus to cumulus transition. The two cases contrast a relatively fast cloud transition in a clean, initially well-mixed boundary layer vs. a slower transition in an initially decoupled boundary layer with higher aerosol concentrations and stronger mean subsidence. For each case, simulations of two neighboring trajectories sample mesoscale variability and the coherence of the transition in adjacent air masses. In both cases, LES broadly reproduce satellite and aircraft observations of the transition. Simulations of the first case match observations more closely than for the second case, where simulations underestimate cloud cover early in the simulations and overestimate cloud top height later. For the first case, simulated cloud fraction and liquid water path increase if a larger cloud droplet number concentration is prescribed. In the second case, precipitation onset and inversion cloud breakup occurs earlier when the LES domain is chosen large enough to support strong mesoscale organization.
Examining College-Level ELLs’ Self-Efficacy Beliefs and Goal Orientation

The present study aims to investigate the self-efficacy and goal orientation of college-level English Language Learners (ELLs). It further explored the relationship between self-efficacy and goal orientation. The data were collected from 198 ELLs by using an English Language Learning Survey. Participants had positive self-efficacy toward their English learning. ELLs who were 25 years old and above had a higher level of self-efficacy than those who were less than 25 years old. Females had a greater mastery goal orientation tendency than males. There was a positive correlation between self-efficacy and mastery goals, whereas self-efficacy was negatively correlated with performance-avoidance goals. Teachers are encouraged to provide scaffolding and set assessment focus on ELLs improvement and mastery of content to enhance their self-efficacy and facilitate adopting mastery goals.
Characterizing the Distribution of Temperature and Normal Stress on Flash Heated Granite Surfaces at Seismic Slip Rates

At seismic slip rates, flash‐weakening can significantly reduce the coefficient of friction, and the magnitude of weakening increases with surface temperature. To quantify the distribution of flash temperature, high‐speed double‐direct shear experiments were conducted on Westerly granite blocks using velocity steps from 1 mm/s to 900 mm/s at 9 MPa normal stress. We employed a high‐speed infrared camera to measure surface temperatures on the moving block during sliding, and utilized a novel sliding‐surface geometry to control the mm‐scale contact history. Following the initial weakening upon the velocity step, the blocks slide at a constant coefficient of friction. Surface temperatures are inhomogeneously distributed across the sliding surface, and increase with displacement. To determine the local normal stress distribution at the mm‐scale, we combine a one‐dimensional thermal model with conventional flash‐weakening models that incorporate a surface temperature‐dependence informed by the controlled, mm‐scale contact history. Early contacts experience local normal stress exceeding 40 times the applied normal stress. As sliding progresses, the local normal stress at the hottest contacts decreases as contact area increases, leading to local normal stresses ranging from 2 to 6 times the applied normal stress on most contacts by 30 mm of slip. Increases in surface temperature, which would decrease the coefficient of friction, are buffered by wear processes that increase contact area and decrease the local normal stress. Treatments of flash heating are advanced by incorporating improved characterization of the state of the sliding surface at the mm and larger scales during sliding.

STAR AND POOR FUND PHENOMENA IN ISLAMIC- AND CONVENTIONAL-FOCUSED FAMILIES: EMERGING COUNTRY EVIDENCE

The aim of this study is to investigate star and poor phenomena and their impact on the flows of Islamic-focused family (IFF) and conventional-focused family (CFF). The sample includes the four emerging countries with the largest number of Islamic mutual funds from 2007 to 2018 (Saudi Arabia, Malaysia, Indonesia, and Pakistan). Panel regression analysis was used to examine the impact of dummy star and poor as independent variables, and family age, size, number of funds, past returns, and total risk as control variables for fund family flows. The results show that the dummy star has a significantly positive relationship with family flows. Family managers have succeeded in attracting more investors by using the strategy of advertising the best performing funds. However, in both, all families and IFF, the dummy poor has a negative relationship, but is insignificant. On the other hand, for CFFs, the dummy poor is significantly negative. This is because investors in IFFs, unlike those in CFFs, have more loyalty due to their moral and religious goals in addition to traditional goals. The novel finding of the study is the difference in the star phenomenon between the IFF and CFF. The findings are important for managers, as they will help them to create appropriate strategies to attract more flows and increase the assets under their management. In addition, the findings will help investors to direct their money to appropriate families.
The impact of plate shape and organization on Americans’ perceptions of Korean restaurants

ABSTRACT This research examines the joint effect of plate shape and plate placement in the context of multiple Korean side dishes, called banchan. Our findings indicate that, when side dishes are presented in an organized manner, round (vs. square) plates elicit more favorable attitudes toward the restaurant. When presented in a less organized manner, there is no significant attitudinal difference between round and square plates. This article further examines the underlying process of the joint effect – perceived warmth of the service staff.
Immune and parasitological response in horses infected with gastrointestinal nematodes in the humid tropic of Mexico

The objective of the study was to determine the parasitological and immune response in horses naturally re-infected with gastrointestinal nematodes (GIN) after an- thelmintic treatment in the humid tropic of Mexico. The study was conducted in Tenosique, Tabasco, Mexico. A total of 30 horses were sampled monthly for nine months. Fecal samples were obtained to determine the number of nematode eggs per gram (EPG) of feces. Stool cultures were performed to obtain and identify infective larvae (L3) genera. Blood samples were also obtained to determine the packed cell volume (PCV), the total plasma protein (TPP), and the differential leukocyte count (DLC). Serum enzyme-linked immunosorbent assays (ELISA) were performed to determine IgA levels against adult cyathostomins and Strongylus nematode antigen. The analyses considered the age and gender of the horses, and the season (Cold, rainy and dry). The number of EPG and TPP were higher in females (1224 ± 1269 and 7.6 ± 0.6 gdL−1, respectively) than males (623 ± 671 and 7.4 ± 0.5 gdL−1, respectively), and no differences were observed with animal age (p > 0.05). The number of EPG increased in the rainy season. The main nematodes involved were of the subfamily Cyathostominae (97.4%) and to a lesser degree of species Strongylus equinus, S. edentatus, S. vulgaris, and Oxyuris equii. The season affected the leukocytes, neutrophils, and lymphocytes counts but not eosinophils. Variables such as gender, animal age, and environmental conditions are important elements for a diagnosis of GIN and the application of treatments for its control.
Urea–formaldehyde resin prepared with concentrated formaldehyde

Abstract The characteristics of UF resin prepared with concentrated formaldehyde were studied in this paper. With the molar ratio F/U = 1.1, the UF resin prepared with concentrated formaldehyde showed better mechanical properties than that with formalin. The 13C-NMR and FTIR results indicated that there were more methylene groups, ether groups and urons in a UF resin system prepared with concentrated formaldehyde than those in a normal UF resin. The differential scanning calorimetry and DMA results showed that the curing temperature of UF resin with concentrated formaldehyde was lower than that of a normal UF resin. UF resin with concentrated formaldehyde showed worse thermal stability and higher thermal decomposition temperature.
High-accuracy multiphase humidity measurements using TDLAS: application to the investigation of ice growth in simulated cirrus clouds

Water vapor is a crucial quantity in cloud studies at the aerosol and cloud chamber AIDA (Aerosol Interactions and Dynamics in the Atmosphere). The chamber is equipped with three tunable diode laser (TDL) hygrometers for the accurate and precise measurement of water vapor and total water concentration as well as liquid/ice water content down to the low ppb range. This thesis presents instrumental improvements, new developments, and assessment of the performance of these instruments – with special emphasis on measurement accuracy. For online evaluation of the AIDA TDL hygrometers’ measurement data, there is demand for a fast, accurate, and robust method which has been developed with the advanced integrative fitting algorithm. Besides utilization at AIDA, this algorithm could find further application in atmospheric trace gas measurements, combustion process analysis, or could be integrated into embedded systems with limited computing power. The capabilities of the AIDA TDL hygrometers have been applied to AIDA experiments investigating ice particle growth within cirrus clouds in the temperature range between 190 K and 235 K. These experiments could constrain the accommodation coefficient of water molecules on growing cirrus ice particles, alpha_ice, which is relevant for the initial stage of ice growth in cirrus clouds. The temperature averaged result alpha_ice=0. 8_(-0.5)^(+0.2) suggests that cirrus ice particle growth is not significantly suppressed as it would be for a low alpha_ice<0.1. Therefore, implications of alpha_ice for cirrus clouds and their characteristics should be minor and future cirrus cloud model studies can rely on a well constrained alpha_ice.
Are Two Heads Better than One? Comparing Engagement between Pairs and Individuals in an L2 Writing Task

This study examined the performance of university foreign language learners on a writing task by comparing paired work (n = 50) against individual work (n = 50). Data were collected based on three aspects of learners’ task engagement: behavioural (time spent working on the task, number of words written), linguistic (English writing scores), and affective (attitudes toward the task). The results showed that (1) all participants worked on the task for the same amount of time and produced a similar number of words, (2) texts written by pairs were similar to and as accurate/fluent as those written individually, and (3) learners who worked in pairs evaluated the task more positively than did those who worked individually. A more detailed examination using cluster analysis revealed that while there was generally a positive relationship between each aspect of task engagement, a trade-off might occur depending on the situation, and one aspect might mediate the effect of others. In addition, by examining the differences between a successful and a less successful pair, this study provides pedagogical implications in relation to the use of pair work activities in the language classroom.
Correlation Analysis of Interpersonal Communication Competence of Corporate Social Responsibility Facilitators, Stakeholder Trust Level, and Corporate Reputation

The problem of communication such as misunderstanding, there is no feedback, and the ineffectiveness of a message often occurs while the company communicates or interacts with stakeholders, moreover runs the CSR program. The communication problems above affected one of the CSR goals. CSR can improve people living in the region around the company like happened in the District of North Semarang because it has the highest poverty rate in Semarang city. Not achieving the CSR objectives will because residents who live around the company have poor judgments against the company and have no trust against the company and so, causes a poor reputation against the company. Moreover, if the company has excessive gas emission and one of them is PT. Indonesia Power Semarang PGU. The research has the purpose of determining if there is a relationship between the effectiveness of interpersonal communication done by the facilitator of CSR and the level of trust beneficiaries with the reputation company of PT. Indonesia Power Semarang PGU. This research is a quantitative research using the theory of communication effectiveness and reasoned action (TRA). Sample this research is Group guidance of PT. Indonesia Power Semarang PGU is the Joint Business Group (KUB) Prima Indosutera in the District of North Semarang. Based on the research results, the effectiveness of interpersonal communication and trust beneficiaries’ level significantly relates to its reputation. The things above showed through the significance value of the hypothesis test performed, more effectively the communication interpersonal has done so. The company’s reputation is better (positive) than such a hypothesis has a significance value of 0.000 (0.000 s of 0.01).

Mindfulness and Next-Generation Members of Family Firms: A Source for Sustainability

Family businesses are considered complex organizations where emotional and management challenges need to be faced. This is even more difficult when time of succession arrives and the new members are expected to engage with the business. In this study, a total of 204 university students were asked about their present and future situation regarding the family business. Mindfulness levels were also evaluated using the Mindful Attention Awareness Scale. There were no significant mindfulness level differences between students who pertained to a family business and those who did not. In the first group, however, those students who were sure about their future in the family business, and had more motivation about it, obtained higher scores on the mindfulness scale as well as being more satisfied with their social relationships. It could be concluded that certainty and motivation about their future in a family business of young family business members correlates with higher mindfulness levels and social well-being.
