The standard bounce formalism for calculating the decay rate of a metastable vacuum cannot be applied to theories in which the symmetry breaking is due to radiative corrections, because in such theories the tree-level action has no bounce solutions. In this paper I derive a modified formalism to deal with such cases. As in the usual case, the bubble nucleation rate may be written in the form Ae...

The surface sterilized grains of Triticum aestivum (L.) cv. HD2204 were soaked in graded concentration (10–10, 10–8 or 10–6) of 28-homobrassinolide (HBR), for 8 h. These pre-treated grains were transferred to sterilized petriplates, lined with filter paper moistened with double distilled water in a B.O.D. incubator, fixed at 25°C. The samples were removed 12, 18 and 24 h of their initial soakin...

In this section we give various parameters for common detector components. The quoted numbers are usually based on typical devices, and should be regarded only as rough approximations for new designs. More detailed discussions of detectors and their underlying physics can be found in books by Ferbel [1], Grupen [2], Kleinknecht [3], Knoll [4], and Green [5]. In Table 28.1 are given typical reso...
