On the Mechanical Stresses Caused by Growth Centers')

The question of the development of mechanical stresses in crystals during their growth is investigated. The mechanical stress field is calculated which can be caused by a radially inhomogeneous impurity concentration distribution existing around growth centers. For the case of KCl: Pb crystals it is shown that depending on growth conditions these stresses can be very considerable.

Die Frage nach der Entstehung von mechanischen Spannungen in Kristallen wahrend ihres Wachstums wird untersucht. Das mechanische Spannungsfeld wird berechnet, das durch eine um Wachstumszentren existierende, radial inhomogene Konzentrationsverteilung der Verunreinigungen verursacht werden kann. Fur den Fall von KC1 : Pb-Kristallen wird gezeigt, daB diese von den Wachstumsbedingungen abhangenden Spannungen sehr betrachtlich sein konnen.

## Abstract The growth of human‐derived A549 lung carcinoma cells is inhibited by activators of protein kinase C (PKC) such as 12‐O‐tetradecanoylphorbol‐13‐acetate (TPA). In this study, the effect of serum deprivation on TPA‐induced growth retardation has been investigated. Cells cultured with 10%
