Fir tree

Figure 7.12 Jagged fir-tree pattern of metal loss caused by condensing steam with high concentrations of carbon dioxide and oxygen.

Fig ure 5-21. This picture shows the rotor blades from the inlet end. Root design is a four-land fir-tree type. A lock pin on each root platform locates the blade axially in the disc.

In 1918 Miss Helene M. Boas, of the New York Botanical Garden, sent to the writer a sample of manna which had been collected by James A. Teit near Spence s Bridge, British Columbia, from Douglas fir trees (Pseudotsuga taxifolia Brit., syn. P. Douglasii Carr.). The dry, white, crystalline manna (42.5 g.), in which some small stems and needles of the tree (4 g.) were encrusted, was entirely soluble in water and it proved to consist principally of melezitose.17 The authors stated that if the manna can be obtained in large quantities, which appears to be the case, it will indeed furnish an excellent source for melezitose. However, there was found within a few months by the same workers an abundant...

Six male specific compounds were isolated from the crucifer flea beetle, Phyllotreta cruciferae, and the same compounds plus two additional compounds were isolated from males of Aphthona flava, A. czwalinae, and A. cyparissiae. Three of the compounds were identified as (-F)-i r-himachalene, (-F)- ra w-a-himachalene (-F)-y-cadinene. Two other compounds were identified as new enantiomers of himachalene hydrocarbons that were previously identified from the fir trees, Abies alba and Abies nordmanniana. Finally, there were two himachalene alcohols and one nonsesquiterpene ketone that is a himachalene analog that were identified. The chemical and electrophysiological patterns are consistent with, but do not prove, a pheromonal function. 

B.I. Shekhter has shown that, if in deton the chges are placed in an acetyl-cellulose tube with walls 0.15 mm thick, the maximum distance increased by 40-50% (Ref 23, p 766) In the section on detonation by influence in condensed media (Ref 23, pp 771-78), it is reported that E. Burlot conducted in France experiments with 50 g charges of PA (Melinite) loaded at density 1.25 in cardboard cartridges of 28 mm diam. When donor and receptor were separated by air, the distance at 50% explns was 28 cm, whereas for water it was only 4 cm for clay 2.5, sand 1.5, fir tree 3.5 to 4 and steel 1.5 cm Shekhter et al detd in Russia (Ref 23, pp 774-78) deton thru various media from a 35.5 chge of phlegmatized (with.6% wax)... 

Balsam turpentine oil is obtained from the resins of living trees of suitable Pinus species by distillation at atmospheric pressure and temperatures up to 180°C, or by other fractionation methods, which do not change the terpene composition of the resins. Wood turpentine oils, on the other hand, are generally obtained by steam distillation of chopped tree trunks, dead wood, or of resin extracted from this wood. Sulfate turpentine oil is produced as waste in the manufacture of cellulose by the sulfate process and is also a wood turpentine. Pine oil is another wood turpentine oil that is obtained by dry distillation of suitable pine and fir trees, followed by fractionation. However, the term pine oil is nowadays used for a product which is manufactured by hydration of turpentine oil (a-pinene). The resulting product is a mixture of monoterpenes containing o-terpineol as the main component. In addition to many other technical purposes, it is used to a large extent in cheap perfumes for technical applications. 

The area surrounding this central plateau is strongly reminiscent of many areas of the western United States, such as northern California and Colorado. There are small, rather scanty strands of fir trees on the upper elevations. In the... 

Commercially available oxidizing reagents were evaluated in the tests. Sawdust used as bedding for animals is a suitable combustible substance. A material for pets produced from boiled fish paste board and American fir tree wood called KURINCHIP, manufactured by Kurea Co. Ltd., was used in these studies. The sawdust should have a... 

From the balsam fir tree Abies balsamea, a sesquiterpenoid, juvabione (Figure 9), was isolated as a compound that has a JH activity that causes the last instar larvae of European linden bug, Pyrrhocoris apterus, to molt into nymphal-adultoid forms.58,59 Since then, a number of phytojuvenile hormones have been detected56 such as juvocimene I and II from the sweet basil Ocimum basilicum60,61... 

Capillary silver, combined with lead-coloured silver in white fluor spars. 13- Capillary silver found in the valley of Joachimica, in a forest of fir-trees. 14- White ore of Anneberg, containing rude, ruby-coloured capillary silver, of transparent appearance. Also rude lead coloured silver clearly distinguished in the same stone. Golden ore and vitreous ore combined, yet clearly distinguished. 

Firs grow best under cool, moist conditions they do not thrive in hot, dry climates. Set container-grown or balled and-burlapped plants into acid, moist but well-drained soil, preferably in spring. Full sun is best, but firs will grow well (with a somewhat more open habit) in partial shade. Fir trees are seldom bothered by insects or diseases in the landscape. Planting healthy trees in the right conditions will help the plants avoid most potential pest problems.
