Sequoia trees

I didn t do (good/well) on my nature project because my bonsai sequoia tree grew real bad in its small container. [Pg.492]

Some other common monoterpenoid hydrocarbons are shown in Figure 3.4. Citronellene is also known as dihydromyrcene. It does not occur in nature but is prepared by pyrolytic cracking of pinane. Hydration of the trisubstituted bond of citronellene produces dihydro-myrcenol which is used to provide fresh notes in perfumery. Further details of both of these processes are given in Chapter 9. a-Ocimene occurs in various essential oils such as those of basil, catnip and magnolia, while the P-isomer occurs in the leaf oils of lemon, orange and grapefruit and also in narcissus flowers. Allo-ocimene occurs in the leaves of sequoia trees and is the thermodynamically most stable of the three ocimenes since the double bonds are all in conjugation and as heavily substituted as possible. Double bonds can be isomerised under... [Pg.48]

Energy relationships within fluids are composed of both potential and kinetic energy terms (Section 2.4). The potential energy of a fluid is related to the height of a fluid relative to some datum, and also to the pressure exerted either by or on the fluid. As examples of these, consider the height of sap within the tallest Sequoia tree. In order to raise the sap to this height above the roots, work must be done to the fluid. The taller the tree, the more work that must be done. The potential energy of the sap at the top of the tree would be available to perform mechanical work if it could be harnessed. [Pg.65]

Aspergillus parasiticus is an endophyte isolated from the inner bark of the redwood tree. Sequoia sempervirens (Taxodiaceae). Previously, several sequoaitones active in the brine shrimp toxicity assay were isolated from this fungal strain and more recently four new sequoaitones C — F (49—52) were isolated and found to be toxic to brine shrimp with LD50 of260 p,M, 1300 xM, 640 xM, and 260 p.M, respectively. ... [Pg.489]

The growth of a tree is always continuous although it becomes slower in the course of time. Giant sequoias (Sequoiadendron giganteum) in Califor-... [Pg.2]

The coastal redwood. Sequoia sempervirens, one of the largest trees, lives at one of the lowest population densities. [Pg.537]

Liquids also exhibit a phenomenon called capillary action, the spontaneous rising of a liquid in a narrow tube. This action results from the cohesive forces within the liquid and the adhesive forces between the liquid and the walls of the container. If the forces between the liquid and the container are greater than those within the liquid itself, the liquid will climb the walls of the container. For example, consider the California sequoia, a tree that reaches over 200 feet in height. Although water rises only 33 feet in a glass tube (under atmospheric pressure), capillary action causes water to rise from the sequoia s roots to all its parts. [Pg.294]

When it comes to emotionally complex moments and situations, if these other art and entertainment forms are giant redwoods, games are still bonsai trees. Isn t it time for these interactive, emotional shrubs to gain a little altitude so they can go one-on-one with the giant Sequoias of film and television ... [Pg.213]
