The sudden shift to distance learning caused by the COVID-19 virus emergency has posed a serious challenge to schools. This article presents a successful model for applying the STEM approach in science education at the Alexander Georgiev-Kodzhakafaliyata Primary School in Burgas. In the conditions of synchronous distance learning in MS Teams environment, students conduct experiments with handy tools and materials at home, during online classes or as homework assignments, then describe the experiments in presentations and share them with their classmates during the project week ( April holidays and at the end of the year). The application of STEM home laboratory combines knowledge from different disciplines, diversifies and facilitates learning, enables learning by doing things, which most stimulates the curiosity of students. Thus, they casually acquire skills for planning and conducting a scientific experiment, generating hypotheses and reasoning, measuring results and formulating conclusions. At the same time, soft skills for teamwork, creative and critical thinking, presentation skills are formed and upgraded.

Single Extractions

The paired Fluvisol and cereal samples in both the field screening and controlled experiments are reported to elucidate the soil–crop relationship for As, Cd, and Pb in relation to changing contamination levels. Significant varietal differences in plant uptake were observed for crop type (barley, triticale) and the harvested part of the crop (oat shoots and grain). When parametrizing the stepwise regression models, the inclusion of soil properties often improved the performance of soil–crop models but diverse critical soil parameters were retained in the model for individual metal(loid)s. The pH value was often a statistically significant variable for Cd uptake. For As and Pb, the more successful model fit was achieved using the indicators of quantity or quality of soil organic matter, but always with lower inherent model reliability compared to Cd. Further, a single correlation analysis was used to investigate the relationship between extractable metal concentrations in soil solution and their crop accumulation. For Cd, there were strong intercorrelations among single extractions, the NH4NO3 extraction stood out with perfect correlation with plant uptake in both experiments. For As and Pb, the CaCl2 and Na2EDTA solutions outperformed other single extractions and were the better choice for the assessment of depositional fluvial substrates.

The article elaborates upon a successful model of postgraduate studies on lean manufacturing. The subject of the research was nine editions of the Kaizen Academy postgraduate studies organized by the Warsaw University of Technology and the Kaizen Institute in the years 2009–2018, that still enjoys interest in the market. A detailed qualitative analysis of this case, followed by a comparative analysis with other post-graduate programs of this type on the national, European, and global level should make it possible to find what is necessary to launch and actively operate for a long time in the (considerably competitive) market of qualification raising programs related to Lean Management (critical success factors). The study has also identified the differences between a successful program, analyzed in detail, and other available programs described in the literature and on the Internet. This has been achieved through a structured analysis of thirty-nine postgraduate programs identified by querying scientific databases and the Google Internet search engine. Best practices and models of postgraduate education on Lean Management have been discussed, and the thirty-nine programs comprising the identified sample have been compared. Considering the very general level of the data available in terms of the organization of postgraduate programs, it has also been assessed if they follow constructivism and experiential learning paradigms. This has been achieved by including the industrial days/visit indicator in the comparison. Given its high value, it has been identified as a success factor of the postgraduate curriculum on Lean Management.

Reduce Emissions

Lubricated transient elastohydrodynamic (EHD) conjunctions are extremely difficult to simulate numerically since lubricant properties such as temperature and viscosity vary significantly during the loading-unloading event. Nevertheless, industry has invested considerable time and effort in trying to create such models in order to improve performance and to reduce emissions and friction. One of the essential requirements for a successful model is accuracy in the implementation of frictional properties. The experimental method presented in this paper used an impact on the end surface of a beam to generate propagating waves that were subjected to fast Fourier transform analysis. The method yielded detailed information about the build-up and decay of normal and frictional forces as a function of time for various lubricants at three different initial temperatures (20, 40 and 80°C) and at relevant EHD pressures. A variety of lubricants were studied to a peak Hertzian pressure of 2.5GPa for loading-unloading times of 200-400 μs (typical for elastohydrodynamically lubricated conjunctions in ball bearings and gears). A qualitative study of the thermal properties of the lubricants and their influence on viscosity and friction coefficient was also undertaken and, finally, a plausible explanation of the observed behaviour is presented and parallels to dynamic simulations of polyatomic gases are drawn.

Essential Contribution

While palliative care is best delivered in an interdisciplinary format, courses teaching the interdisciplinary approach to palliative care are rare in healthcare education. This article describes a graduate-level course in palliative care for students in nursing, pharmacy, social work, and gerontology taught by faculty from each discipline. The overarching goals of this course are to convey core palliative care knowledge across disciplines, articulate the essential contribution of each discipline in collaborative care, and to define interdisciplinary processes learners need to understand and navigate interdisciplinary palliative care. Learning outcomes included increased knowledge in palliative care, enhanced attitudes in practice and application of skills to clinical practice settings, increased ability to contribute discipline-specific knowledge to their teams' discussions, and a sense of increasing confidence in participating in the care of complex patients, communicating with families, and contributing to the team as a member of their own discipline.
