Kinetics of pearlite spheroidization
Archives of Metallurgy and Materials, 2017 The pearlite spheroidization in Fe-0.76%C high purity steel was investigated. The samples of a coarse pearlite microstructure were isothermal annealed at 700, 680, 660, 640 and 620°C for various times, up to 800 hours. For quantitative description of the

Intercellular Communication in Spheroids [PDF]
, 1984 This chapter has shown that the response of spheroid cells to gap junctional communication may lead to certain metabolic and cell physiological changes. It has also become apparent that the functions of the gap junctions are very complex. They may, for example, be related to the fundamental effects of cAMP and/or Ca 2+.
