Transferability of Fracture Mechnaical Characteristics
Dlouhý, Ivo ; Lenkey, G. B. ; Pluvinage, G.
Comprehensive review of proved recent methods for transfer of fracture mechanical characteristics from smaller to standard specimen geometry is supplied thinking at the same time on transferability of these characteristics from laboratory experiments to real components. Application procedures for local approach, master curve methodology, toughness scaling models, dynamic fracture properties and notch sensitivity are workout and discussed.

Learning, MRI and structural changes of the rat hippocampus 1 ro 12 months after irradiation with the leksell gamma knife
Náměstková, Kateřina ; Liščák, R. ; Herynek, V. ; Burian, M. ; Jirák, D. ; Hájek, M. ; Brožek, G. ; Mareš, V. ; Syková, Eva
The lower the dose of irradiation with the LKG, the more delayed are the structural and functional changes in hippocampus.

Neuron-glia communication by extrasynaptic transmission
Syková, Eva
Dynamic changes in ECS ionic composition, volume and geometry accompany neuronal activity, neuronal loss, glial development and proliferation, aging, CNS injury, anoxia/ischemia, spreading depression, tumors, inflammation dyemyelination and many other brain pathological states.
