The division of the regions of Ukraine into "red", "orange", "yellow" and "green" zones are the consequences of the differentiated regional impact of the pandemic caused by the COVID-19 virus, but the reasons for such different vulnerabilities have n

Abstract Aims Despite recent advances in guideline‐directed therapy, rehospitalization rates for acute decompensated heart failure (ADHF) remain high. Recently published studies demonstrated the emerging role of hypochloraemia as a predictor of poo

The refining of plant fibre, particularly wood fibre, in a disc refiner involves changes in its geometric parameters and fraction proportions in the general semi-finished material mass. Fibre disintegration nature and intensity largely depend on the

Refining of fibrous semi-finished products is an important stage in fibreboard production because the efficiency of this stage affects the resulting fibres’ dimensional and qualitative characteristics. These, in turn, determine the physical and mec

A rationale is presented for the wood fibre process modeling of internally recycled content in fibreboard production. Experimental studies were employed to obtain mathematical dependences in order to confirm the possibility of reusing wood fibre at v
