The True Tree

The true tree cannot be had as a result of empirical research. 

Determining which accident sequences lead to which states requires a thorough knowledge of plant and process operations, and previous safety analyses of the plant such as, for nuclear plants, in Chapter 15 of their FSAR. These states do not form a continuum but cluster about specific situations, each with characteristic releases. The maximum number of damage states for a two-branch event trees is 2 where S is the number of systems along the top of the event tree. For example, if there are 10 systems there are 2 = 1,024 end-states. This is true for an "unpruned" event tree, but. in reality, simpler trees result from nodes being bypassed for physical reasons. An additional simplification results... 

For example, consider the two trees shown in figure 12.4. The tree in figure 12.4-a has equal (binary) subtrees, so that its diversity V = 1 and complexity C = 0. The same is true for any tree all of whose nodes have a constant branching ratio. On the other hand, the tree shown in figure 12.4-b has two distinct subtrees, each of which has a diversity of 2 = 1. The diversity of the entire tree is therefore X) = 22 - 1 = 3. 

This compares to the exact result of 0.0702 obtained using the actual fault tree. The cut sets are related to each other by the OR function. For Example 11-6 all the cut set probabilities were added. This is an approximate result, as shown by Equation 11-10, because the cross-product terms were neglected. For small probabilities the cross-product terms are negligible and the addition will approach the true result. 

Each end of the rod of power Is ornamented with a tree s fruit the almond nut and the pine cone. This, the true wand of practitioners of the Great Work, is internal. It is described by Eliphas Levi in his Sanctum Regnum and shown in the suit of Wands in the tarot designed by Paul Foster Case as having identical crystals (more accurately diamonds), one bright and one dark, on either end of the rod, just as, on the simple... 

Both true mistletoe and dwarf mistletoe are common parasites of forest tree species. The true mistletoes Phoradendron spp.) occur commonly on... 

California black oak and white fir and less often on incense cedar in the San Bernardino Mountains. No direct effects of oxidants have been noted on the mistletoe plant itself under field conditions. The true mistletoe obtains mainly water from its host and would be indirectly affected by debilitation of die host tree. The dwarf mistletoes Arceuthobium spp.) are common on ponderosa, Jeffry, and sugar pines in the San Bernardino National Forest. They depend on their host for both water and carbohydrates. Heavily infected or broomed" branches on ponderosa or Jeffrey pines severely injured by ozone often have more annual needle whorls retained than do uninfected branches on the remainder of the tree. The needles are also greener. It can be hypothesized that the infected branch is a carbohydrate sink where a pooling of carbohydrates occurs higher carbohydrate concentrations may be instrumental in either preventing or helping to repair ozone injury to needles on the broomed branches. In the long term, stresses from mistletoe and ozone are probably additive and hasten tree death. 

The production of natural camphor and camphor oils was formerly several thousand of tons per year, but has declined as a result of the production of synthetic camphor. The same is true for the distillation of linalool-containing camphor oils (Ho oil. Ho leaf oil), which are derived from other varieties of the camphor tree.
