Caloric materials for cooling and heating

Magnetically driven thermal changes in magnetocaloric materials have, for several decades, been exploited to pump heat near room temperature. By contrast, their electrocaloric and mechanocaloric counterparts have only been intensively studied and exploited for little more than a decade. These different caloric strands have recently been unified to yield a single field of research that could help combat climate change by generating better heat pumps for both cooling and heating. Here we outline the timeliness of the present activity and discuss recent advances in caloric measurements, materials, and prototypes.

Short Position Disclosures and Underlying Stock Performance: Evidence from Polish Stock Market

After introducing EU Regulation on short selling and certain aspects of credit default swaps, in 2012, investors holding a significant short positions are obliged to disclose it in a public manner, through the local supervisor registry. Beside the intended transparency, such a registry also have a cogent influence on behaviour of market participants. The Multimillion euros worth of short position is a strong view on underlying stock perspective, to say the least. Thus, many investors do care about the public disclosures of short positions and some of them manage their portfolios accordingly. The aim of herein paper is to provide quantitative assessment of stock performance following short position announcement and present activity of short selling investors on Polish stock market. The research hypothesis verified in this study stated that the prices of short sold stocks are exhibiting significant downward trend relative to the benchmark in a half a year period after disclosure.

Back to the Future Consequences: Consideration of Future Consequences (CFC) Measure Correlates with Exercise Intensity

From training for a marathon to completing a college degree, long-term goals are used to accomplish several highly-valued life achievements. These goals require present activity with predominantly future benefits, a tradeoff that requires individuals to exert self-control as they work toward their goals. While these goals are highly valued, people frequently fail at achieving them. What individual and situational differences allow some people to succeed at working toward future goals? To address this question, we measured trait and motivational differences alongside exercise behavior, an activity with predominantly future benefits, in a campus gym. Specifically, we measured how the amount people report thinking about and working toward the future, a trait captured by the Consideration of Future Consequences (CFC) questionnaire, correlates with workout behavior. We find that CFC scores predict several aspects of exercise including frequency of engagement, intensity of exercise, and perceived benefits associated with the activity. Overall, our study provides evidence that high CFC individuals, who pay greater attention to future outcomes, exhibit increased present performance to achieve them, a finding that provides evidence on how to aid in the achievement of long-term goals.

Toward next JENDL Fission Yield Data and Decay Data

JENDL group has developed evaluated fission yield and decay data. They are now planned to be upgraded in order to embody new experimental data and theoretical developments obtained after the last release. In this paper, we briefly describe a plan and present activity toward next JENDL fission yield and decay data.

TRIBOTECHNICAL CHARACTERISTICS OF CARBON-BEARING LUBRICANTS

The development of technology for manufacturing nanostructured substances in amounts that could suffice an interlaboratory research is a high priority task for the implementation of nanoproducts. The ultra dispersiblis clusters of synthetic carbon are used as on extra component in polymeric materials. The substances have a high dispersibility and activity of the surface. To study properties of mineral oils, modified ultra dispersiblis clusters of synthetic carbon is of interest. The present activity is devoted to the research of the modifying influence of ultra dispersiblis clusters of synthetic carbon on viscosity of the characteristic of mineral oils and their stability at various temperatures. In the preparation of diamond secondary suspensions not only statistic average sizes of particles should be taken into consideration, but also polydispersity parameters of nanodiamond particle population too.

Student Time Usage During Fall Reading Week

The present study investigated the time usage and relative levels of perceived stress, academic workload, and recreation time for 177 students at a mid-sized Canadian university before, during, and after Fall Reading Week. Across three weeks, and at various times of the day, students received a message to their smartphone to complete a 20-second survey that assessed present activity, and levels of stress, academic workload, and recreation. Results showed that student stress following the break was higher with more stress but less workload prior to reading week, more stress experienced during reading week, more workload following reading week; and more time spent recreating during reading week. Implications for student counselling are outlined, which encourage students to seek a balance in time usage and management. Future directions are discussed.
