Grass dried

Hydrogen peroxide concentrations of 35% and above may, and 50% and above do, cause spontaneous combustion of dry grasses, wood, and leaves. Spills of concentrated hydrogen peroxide should be diluted with excess amounts of water immediately. Practically all soHd combustible materials contain sufficient quantities of catalytic impurities to rapidly decompose hydrogen peroxide, especially at 70% concentration and above. 

Reactivity. Bromine is nonflammable but may ignite combustibles, such as dry grass, on contact. Handling bromine in a wet atmosphere, extreme heat, and temperatures low enough to cause bromine to soHdify (—6° C) should be avoided. Bromine should be stored in a cool, dry area away from heat. Materials that should not be permitted to contact bromine include combustibles, Hquid ammonia, aluminum, titanium, mercury, sodium, potassium, and magnesium. Bromine attacks some forms of plastics, mbber, and coatings (62). 

Common materials—such as textiles in the form of fibers or fabrics, foamed rubber, foamed plastics, thin sheets of plastic, paper, corrugated cardboard, combustible dusts, dry grass and twigs, and wood shavings—are all examples of materials with large sutface areas in relation to their volumes. In a well-estabhshed fire, materials with relatively small surface areas, such as chunks of coal or logs, burn readily. 

From the organic standpoint, early lambing is the least natural , partly because of the length of the housing period for the lambs and partly because the easiest and most reliable way to guarantee lamb growth indoors is to feed either concentrates or dried grass pellets. These are expensive and can only be fed to a certain level in the ration, as defined in the Soil Association Standards.

Vitivert, or Kus-hus.—The fleshy part of a specter of dry grass from India, It has an aromatic odor, and is used in the same manner as orris root. The tincture or extract of vitivert is made by digesting one pound of the dried root in a quart of alcohol for two weeks, and filtering. This tincture was formerly much used In bouquet combinations, and was an important ingredient in the once celebrated preparations of that kind called mousselaine des Indes, bouquet du rot, et cetera. By distillation, it yields about one per cent, of volatile oil called otto of vitivert, and resembling, according to Piesse, the otto of santal. 

There have been only a few citations in the literature concerning the extraction and recovery of natural chlorophyll pigments. Chlorophylls, despite their high molecular weights, are soluble in pure CO2 (like pheophytin a at 500 bar and 55°C), or in the presence of an entrainer (like copper chlorophyllin at 60 bar and 20°C with 5% ethanol entrainer). The extraction of dried grass resulted in 1.56 wt.% yield of green components [79]. 

The results of the field experiments are summarised in Table 6.4. The velocity of deposition of Lycopodium spores to dry grass and cereal crops was about twice the sedimentation velocity, so vv and vt were about equal. When the cereal crop was thoroughly wetted, v, was about twice vv. 

Palmarosa Oil occurs as a light yellow to yellow oil that is often hazy and brown with a rosy, floral, geranium odor. It is the volatile oil obtained by steam distillation from the partially dried grass Cymbopogon martini Stapf. var. motia (Fam. Gramineae). It is soluble in most fixed oils and in propylene glycol. It is soluble, usually with opalescence or turbidity, in mineral oil. It is practically insoluble in glycerin. 

The body of Bess, Sale s Border collie, lay in the dry grass. It looked tir, its fiir dusty and matted. I batted away the flies that left it to inspect ny fiesher meat and turned away. But not before I d seen how the dog s head had been almost severed.

A small additional contribution may be expected in form of dry grass, roadside and spoiled hay, which is unsuited as animal food. A small contribution from 3% of the grassland area results in 0.12 Gt/y C (3% from 4.2 Gt C total grass up-growth per year) or 1% of our present primary energy consun tion.
