Flow cytometric analysis of the transfer of liposome-encapsulated carboxyfluorescein to isolated rat liver nuclei indicated that the fluorophore is actively taken up in this form, while negligible amounts are transferred when the dye is free in the reaction medium. The kinetic analysis of the uptake indicated a time- and dose-dependent reduction of the(More)
The characterization of mixed-mode fracture toughness and fatigue delamination growth in fibrereinforced composites is crucial for assessing the integrity of structural elements in service. An asymmetric cut-ply coupon (ACP) loaded in four-point bending is here proposed to carry out the aforementioned characterisations. Analytical expressions of the energy(More)
The interaction between phosphatidylcholine vesicles and isolated rat liver nuclei has been examined by studying the uptake of the fluorophore carboxyfluorescein. The kinetics of transfer of the dye, analyzed by flow cytofluorimetry with a Fluorescence Activated Cell Sorter (FACS IV), indicate an efficient delivery to the nucleoplasm. The results reflect a(More)
A constitutive model for tufts bridging a mode I delamination is presented. The tuft is modelled as a rod, laterally supported by an elastic medium and clamped at both ends. A fracture mechanics approach is introduced to describe the progressive debonding of the tuft from the embedding laminate. The debonding model requires the identification of stiffness,(More)
