Budding regime

The latter discussion shows the importance of the interplay between buoyant forces and the physical characteristics of the freshly formed membrane. We note that these factors also control the transition from popping to budding dynamics (see Figure 11.4). However, in the budding regime, the buoyancy of the droplets is too weak to cause their detachment and the continuing expansion is only limited by the occurrence of small ruptures that nucleate new growth buds. 

As the concentration gradient further increases (regime C), the radius of curvafure of premixed wings l cur decreases. When if becomes comparable wifh, for example, the preheat zone thickness Sj, typically O (1mm), one or both of fhe premixed flame wings can be merged to the trailing diffusion flame by having a bibrachial or cotton-bud shaped structure. 

Franz (22) reported that the yield and composition of the oil of Artemisia dracunculus increased with less frequent water regime. He found that the plants really only needed to be irrigated during critical stages of growth such as shoot formation, secondary shoot formation, flower bud formation and after harvesting. 

The standard cold acclimation program used for pine consisted of both a decrease in photoperiod from 17 to 8 h to induce bud formation and a decrease of the PPFD from 250 to 50 umol rn s" when the seedlings were transferred to the cold hardening temperature regime of 4 (2). To address the question of whether cold acclimated... 

Figure 11.4 Image sequences of tube growth in the popping (a-h), jetting (i-l), and budding (m-p) regimes. In all experiments, aqueous cupric sulfate solution is injected into sodium silicate solution (100ml, 1 M in Si, 25°C). Injection is carried out with a syringe pump at constant flow rate (here 7.0 ml h ) through...

Figure 11.5 Image sequences illustrating four reverse growth regimes observed for the injection of sodium silicate (l.OM) into cupric sulfate solution. The growth regimes are referred to as (a) jetting (b) popping, (c) budding, and (d) fracturing. Flow rates, cupric sulfate concentrations, and density differences are (a) 50.0 ml h ...
