Ridge growth

Figure 7.6 Schematic representation of various growth forms observed in metal deposition (a) layer growth, (b) ridge growth, (c) block growth, (d) pyramidal growth, and (e) dendritic growth.

The above summarized mineralogical and geochemical studies on Kuroko and Mariana chimneys (Shikazono and Kusakabe, 1999), and previous studies on midoceanic ridge chimneys, combined with the studies of mineral particle behaviors in the plumbing system, are used to develop the following plausible model for the growth history of sulfate-sulfide chimneys on the seafloor (Shikazono and Kusakabe, 1999).

Barnes et al. (44) observed similar results on copper single-crystal surfaces near the (100) face below 10-mV ridges, 40- to 70-mV platelets, 70- to 100-mV blocks, and fine platelets and above 100 mV, polycrystaUine depKJsit. The four basic structural forms are shown in Figure 7.19. Less frequently observed growth forms are p5namids, spirals, whiskers, and dendrites. The structure of depKJsits is discussed further in Chapter 16.

Fibroblast growth factors are expressed in the apical ridge of vertebrate limb buds and mediate bud outgrowth. Two fibroblast growth factors (acidic FGF and basic... 

One problem that can be encountered with roller bottles is the build up of static electricity which can affect the evenness of cell growth causing bands of densely packed cells to form around the bottles. This is partly overcome if the bottle contacts the rollers only at special ridges which are incorporated one at each end of the modem plastic roller bottle.
