The presence of over a million Ukrainian immigrants in Poland has inspired various analyses and studies. They seek to answer the question how this largest group immigrants, living mainly for economic educational purposes,will influence course discussions on social, political, cultural and, finally, consequences migration.
 Yet another question, which author article is attempting answer, co...

We introduce the k-stellated (combinatorial) spheres and compare and contrast them with kstacked (triangulated) spheres. It is shown that for d ≥ 2k, any k-stellated sphere of dimension d bounds a unique and canonically defined k-stacked ball. In parallel, any k-stacked polytopal sphere of dimension d ≥ 2k bounds a unique and canonically defined k-stacked (polytopal) ball, which answers a quest...

Using 192 petitions from the Staffordshire and Worcestershire Quarter Sessions, this article questions whether petitioning culture in early modern West Midlands supports idea of ‘decline neighbourliness’. It frames group as an inherently social neighbourly (yet performative) act which a signatory was entering into exchange ‘social capital’. Ultimately, it is argued that mentions immoral behavio...

dumpsites can produce serious pollution problems in soil, water and air, and are the most frequent method of solid waste disposal in many developing countries. one of the pollution concerns at dumpsites is the emission of methane, which has been identified as a green house gas. in order to determine the surface emission of methane at an informal settlement built on a former dumpsite, six sampli...

prediction of mechanical properties of carbon nanotube-based composite is one of the important issues which should be addressed reasonably. a proper modeling approach is a multi-scale technique starting from nano scale and lasting to macro scale passing in-between scales of micro and meso. the main goal of this research is to develop a multi-scale modeling approach to extract mechanical propert...
