Early Effects of Growth Substances [PDF]
Nature, 1952 ISOLATED cambium – phloem strips from Bryophyllum calycinum Salisb. show a curvature with the cambium at the concave surface, and this curvature is increased when the strips are placed in water. Plasmolysis causes the complete relaxation of the strip.

The Growth of Plant Embryos in Vitro. Preliminary Experiments on the Rôle of Accessory Substances [PDF]
, 1937 The aseptic culture of plant embryos isolated from the seed dates back to the work of Brown and Morris,(1) Hannig(2) and Dietrich.(3) More recent contributions to our knowledge concerning the culture in vitro of excised embryos have been made by Tukey,(4)

Self-Wiring of Neural Networks [PDF]
, 1997 In order to form the intricate network of synaptic connections in the brain, the growth cones migrate through the embryonic environment to their targets using chemical communication. As a first step to study self-wiring, 2D model systems of neurons have been used. We present a simple model to reproduce the salient features of the 2D systems.

GROWTH INHIBITION BY SUBSTANCES IN LIVER [PDF]
Journal of Experimental Medicine, 1940 Certain tissue constituents inhibitory to cell growth, extracted from liver, are described. The findings indicate that inhibitory material is adsorbed to colloids in the native state and is freed from them by alcohol extraction. One inhibitor, ethanolamine, has been isolated.

Mechanisms of Dendrites Occurrence during Crystallization: Features of the Ice Crystals Formation [PDF]
, 2007 Dendrites formation in the course of crystallization presents very general phenomenon, which is analyzed in details via the example of ice crystals growth in deionized water. Neutral molecules of water on the surface are combined into the double electric layer (DEL) of oriented dipoles; its field reorients approaching dipoles with observable radio ...

Growth Techniques for Bulk ZnO and Related Compounds [PDF]
MRS Proc. 1394 (2012) mrsf11-1394-m10-01, 2011 ZnO bulk crystals can be grown by several methods. 1) From the gas phase, usually by chemical vapor transport. Such CVT crystals may have high chemical purity, as the growth is performed without contact to foreign material. The crystallographic quality is often very high (free growth).
