GBM stem cells have molecular hallmarks of neural stem and progenitor cells and it is possible to propagate both non-transformed normal neural stem cells and GBM stem cells, in defined, feeder-free, adherent culture.
By changing these experimental conditions it is possible to propagate longitudinal and shear waves in the different tissues present in these leaves (spongy mesophyll, chlorenchyma and sclerenchyma fibres) and in different directions so it is possible to determine their ultrasonic properties (velocity and attenuation) and hence their main elastic mudulii.
Although the chances of success are extremely low, it is possible to propagate lilacs by taking a cutting from an established bush.
It is found possible to propagate magnetic interaction through hydrogen bonding, although the effect is small.
It is also possible to propagate a difference in activity between A- and N-neurons, if A-neurons excite neighboring A-neurons with N-neurons providing inhibition.
It is also possible to propagate pohutukawa from semi-hardwood cuttings.
Although it is known that teleost fish scales are extremely tough, actual measurements of fracture toughness have so far not been reported because it is simply not possible to propagate a crack in this material using standard fracture testing configurations.
It did not prove possible to propagate a complete cDNA of potato SBEII in Escherichia coli, so an alternative strategy was employed.
Maxwell's insight on displacement current, therefore, made it possible to understand electromagnetic waves as being propagated through space completely detached from electric currents in conductors.
The various experiments carried out showed the harmfulness of a thermal loading, which makes it possible to rapidly initiate a network of cracks and to propagate one (or some) cracks through the total thickness of the component under certain conditions.
