In equation (4.25), u , the velocity at the transition from the active layer to the plug flow, is a function of radius only u = r but the radius for this transition requires knowledge of the active layer depth, x , at that distance, x, from the apex. from the geometry in figure 4.9 it can be shown that r.
Introduction. trehalose 6-phosphate (tre6p) is a potent signaling molecule in plants. the enzyme responsible for its biosynthesis, trehalose-6-phosphate synthase (tps; ec 22.214.171.124), is essential for plant viability (eastmond et al., 2002; van dijken et al., 2004; g mez et al., 2010).tre6p is the phosphorylated intermediate in the two-step pathway of trehalose biosynthesis (cabib and leloir.

Microporous calcite was obtained only when carbonated at 600 c using ca(oh)2 compact made with 0.2 mpa even though thermogravimetry analysis showed that calcite powder was stable up to 920 c under co2 atmosphere. cao formed by carbonation at 700 c and 800 c is thought to be caused by the limited co2 diffusion interior to the ca(oh)2.

They were blank diameter (100 and 110mm), blank thickness (0.8, 1 and 1.2 mm), standoff distance (130, 150 and 170 mm) and half apex angle of cone (45 and 60 degree). height of deformed cone was measured after each test and these results was used an indicator for.
Twenty-four archaeological human and faunal bone samples (5 heated and 19 unheated) of different chronological age (neolithic to post-medieval) and origin (belgium, britain, denmark, greece) were.
Wet grinding is almost exclusively performed in alsing or ball mills (fig. 5). this type of mill has a discontinuous work cycle. the entire work cycle is divi-ded into three phases: 1) loading of raw materials, water and rheological additives (usually defloccu-lants). 2) grinding. 3) unloading of the obtained.
Where, m da is the dry mass of the aliquot (g), m ft is the total tissue fresh mass (g) and m fa is the fresh mass of the aliquot (g). during the harvest, the following fresh tissues were used for gus staining: one half of the shoot apex, leaf disks (diameter 5 mm) from young leaves (not fully developed leaves which were seen just below the stem apex), stem cross-sections (2 mm thickness) from.
