The rheological behavior of model suspensions with the silicone oil M20000 and different concentrations of Cab-o-sil TS 720 resp.Durcal 5 are compared.The increase of the Cab-o-sil concentration changes the flow behavior of the suspension from shear-thinning, to pseudoplastic, and to plastic flow behavior.The first normal stress difference ventilat
Innovativeness is an important determinant of changes in the modern economy.These changes occur in all its areas, here including the labour market, where the workforce adjusts to the needs of innovative economy.The aim of the paper is an attempt to capture the relationship between the innovativeness and changes occurring in the labour market in Pol
The 80% ethanol extract of Alstonia yunnanensis afforded five new monoterpenoid indole alkaloids: 11-hydroxy-6,7-epoxy-8-oxo-vincadifformine (1), 14-chloro-15-hydroxy- vincadifformine (2), perakine N4-oxide (3), raucaffrinoline here N4-oxide (4), and vinorine N1,N4-dioxide (5), together with three known compounds: 11-methoxy-6,7-epoxy-8-oxo- vincad
Abstract Background Subcutaneous immunotherapy (SCIT) is the standard approach for treating patients with sensitizations to aeroallergens.However, immunotherapy can trigger severe systemic reactions if delivered inappropriately or to high risk patients.We sought to characterize and quantify SCIT systemic reactions requiring epinephrine administrati
Abstract During Central Nervous System ontogenesis, myelinating oligodendrocytes (OLs) arise from highly ramified and proliferative precursors called oligodendrocyte progenitor cells (OPCs).OPC architecture, proliferation and oligodendro-/myelino-genesis are finely regulated by the interplay of cell-intrinsic and extrinsic factors.A variety of extr
