ABSTRACT Marchantia emarginata Reinw., Blume & Nees, with nearly 30 assigned names, is considered the most taxonomically complex species in the family Marchantiaceae.Currently, this species is segregated into three subspecies, and this subspecific classification is widely accepted since its formal inception.However, due to its extensive morphologic

Mixed matrix membranes (MMMs) have shown great potential in pervaporation (PV).As for many FR Shirts novel membrane materials however, lab-scale testing often involves synthetic feed solutions composed of mixed pure components, overlooking the possibly complex interactions and effects caused by the numerous other components in a real PV feed.This w

The paper contains plane strain analysis of uniformly stretched plate working in creep condition.The plate contains initial defects in forms of central and/or edge cracks working in mode I.These cracks are modelled by attributing critical value of damage parameter to preset points and therefore resulting in stresses set to zero (material does not s

The paper present theoretical and experimental studies of the energy dissipation performance of a composite structure composed in a multilayer nano-composite damping coating applied on a tungsten carbide shim and placed beneath the cutting insert.The coated shim placed closed to the cutting zone BEDSIDE is subjected to high compressive and shear st

An entirely unelected Upper House looks, at first sight, to sit uneasily with a XXIst century democracy.In this context, the House of Lords has had to carve out its own role in the British constitutional settlement.Since the reforms Outdoor Swing Sofa of the beginning of the XXIst century, its legitimacy and positions have shifted.This article focu
