The Impact

This study provides a better understanding of the effect of density and thickness on impact strength of laminated floor panel from Kenaf high density fibreboard (KHDF). The objective of this study was therefore to determine the role of density and thickness on the impact strength of laminated floor panel. Laminated floor panels consisted of high density fibreboard (HDF) as core and decorative paper as surface layer and backing. Kenaf bast fibres were used for HDF with three different densities (850, 960 and 1000 kg/m3) with thickness of 8mm and 12mm for each panel. Energy (J) value was evaluated to determine the impact strength of all various floor panels. It was found that thickness has affected statistically on impact strength while there was no significantly difference existed on density of laminated floor panel on impact strength.

Operation Characteristics

The assessment indices of surface layer effective state in machinery subjected to different ways of finishing are considered. The role of the dislocation restructurization process in the formation of operation characteristics of surface layer material quality and prediction of its working capacity is shown. A generalized quality index of multi-component functional layers formed on operation surfaces of machinery is described.

Putative Role

The composition and properties of apolipoprotein (apo) A-I and apoA-II in high-density lipoproteins (HDL) might be critical to SARS-CoV-2 infection via SR-BI and antiviral activity against COVID-19. HDL containing native apoA-I showed potent antiviral activity, while HDL containing glycated apoA-I or other apolipoproteins did not. However, there has been no report to elucidate the putative role of apoA-II in the antiviral activity of HDL.
