Forest residues typically refer to those parts of trees such as treetops, branches, small-diameter wood, stumps and dead wood as well as undergrowth and low-value species. The conversion of wood to biofuels and biochemicals has long been a goal of the forest products industry. Forest residues alone count for some 50% of the total forest biomass and are currently left in the forest to rot (Demirbas, 2001). 

What to do Select resistant cultivars remove and destroy affected plants and plant in well-drained soil. Avoid touching plants when wet Prune out dead wood and collect and destroy infected leaves. 

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 selected wood, whatever its variety, should always he cut when in sap, and never when dead. Wood of five or six years growth is better suited for the manufacture of the charcoal than older Irinds for, generally, the latter contains more mineral matters, and, consequently, less oarbon than the former and the most convenient size is branches from three-quarters to an inch in diameter. ... 

A limited form of excitotoxicity may be useful as a pruning mechanism for normal maintenance of the dendritic tree (see Fig. 1—23), getting rid of cerebral dead wood like a good gardener however, excitotoxicity to an excess is hypothesized to cause various forms of neurodegeneration, ranging from slow, relentless neurodegenerative conditions such as schizophrenia and Alzheimer s disease to sudden, catastrophic neuronal death such as stroke (Fig. 10—26).

To flourish and bear well, citrus trees require a site with excellent drainage and full sun. Prune to remove dead wood, to keep trees in bounds, and to thin out centers where growth is too dense. Citrus flowers attract bees don t plant them in high-traffic areas. Citrus trees bear fruit without cross-pollination. 

Fruit with small, brown, sunken spots that turn dark and are raised. Cause Melanose. This fungal disease usually attacks trees more than 10 years old and is worst in wet springs. As rain washes spores over fruit, a tear-streaked pattern of infection develops. Copper spray applied just once at fruit set controls this disease, but since fruit damage is only cosmetic, spraying isn t really necessary. Keep melanose in check by pruning out dead wood, which may harbor the disease. 

On trees, prune out the dead wood and the water sprouts. Avoid drought stress by watering trees during dry spells and keeping the root zone mulched. Gather up and destroy infected leaves. A dormant spray of bordeaux mix may provide some control. 

Always try to cut empty deadwood from your sentences. Having a clear, concise style does not mean limiting your writing to choppy, childish Dick-and-Jane sentences it only means that all unnecessary words, phrases, and clauses should be deleted. Here are some sentences containing common dead-wood constructions and ways they may be pruned ... 

The word on South Dakota is that there s the Black Hills and Mount Rushmore on one side, Sioux Falls on the other and a whole lot of empty space in between. The culinary scene certainly follows suit. You can pull off some good meals on both sides of the state. On the west side of the state, you ll find vegetarian dishes in Dead-wood, Spearfish and Rapid City, while the east side you ll find options in Sioux Falls. 

All have their own distinctive flavors and crop successively through the summer and fall. An orchard is also a magnet for wildlife, especially pollinating insects such as bees and hoverflies, birds such as redwing blackbirds, butterflies, and small mammals, which all feed on fallen fruit. Once the trees mature, countless invertebrates and insects will feed on and live in any dead wood, and birds such nuthatches, woodpeckers, and tree creepers will nest in hollow trunks. 

Leave a few piles of dead wood on the ground, which will be used by a wide variety of invertebrates, and serve as a shelter for frogs, toads, and newts. 

Lovelock defines Earth as a living organism, first of all, because of its homeostatic properties. But he draws also some other analogies to show how close the concept of Gaia is linked with the concept of life. Perhaps the most illustrative is his morphological redwood tree - argument. The tree undoubtedly is alive, yet 99 percent is dead" (Lovelock, 1989b, p, 27). Dead wood of a tree can be compared with the apparently inanimate rocks of the Earth. 

Under forest fallow the rate of turnover of the nutrient elements is very rapid, according to Nye and Greenland (1960), and after a few years exceeds the rate of storage in the fallow. In addition to the nutrients in the litter fall, considerable phosphorus and potassium are leached from the green leaves, and the dead wood contains considerable calcium. About five tons per acre of dry litter falls on the soil annually, and most of it decomposes rapidly. The amount of nutrients added in the rain and as dust is very small in comparison with the amounts involved in natural cycling.

L. is a component of the East Asian edible mushroom shiitake (Lentinus edodes, Basidiomycetes) and, together with the polythiepanes and 1,2,4-trithioIane shown in the formula scheme, is responsible for the characteristic odor of the mushroomPrecursors of this flavor substance are 2,4,5,7-tetrathiaoctane 2,2,7,7-tetraoxide and 2,3,5,7,9-pentathiadecane 9,9-dioxide (SE-3), the structures of which were confirmed by synthesis (see also dysoxysulfone). The cyclic flavor substances can be prepared simply by reaction of dichloromethane with NajSj.s (from NajS and sulfur)Shiitake mushrooms - cultivated on dead wood - are becoming increasingly popular in Europe and North America on account of their excellent flavor. L. is also found as a volatile component of cooked mutton and in the alga Chondria californica. ... 

Carbohydrates occur in all forms of life, and survive in plant and animal tissues for varying periods thereafter. Cellulose and the hemicellulosic components of dead wood decompose eventually under the action of enzymes secreted by fungi, whereas soluble carbohydrates disappear rapidly from plants and animals following well-established metabolic pathways. Industrially important carbohydrates, available in...
