Seeding amount

The recommended seed amount is at least of 10-15% (the amount necessary to maximize growth by providing sufficient initial surface area to minimize nucleation). 

Neither of these seed amounts is satisfactory since the lower amount will result in excess nucleation and the higher amount will result in only a limited increase in the size of the basic needles. 

Set up experimental program with appropriate parameters, including impeller type, speed, seed amount, seed size, rate of cooling or addition, point of addition. 

From pilot plant results, determine variables—agitator speed, cooling/addition rate, seed amount and timing, effect of point of addition—which contribute to differences in chemical purity and physical attributes.

ANETHOLE Up to 90+% in anise seed oil, 70+% in fennel and star anise oils, and in varying amounts in betel leaf, dill seed, carrot seed and coriander oils. 

APIOLE 23% of celery leaf oil, up to 30% in parsley leaf and seed oils, and in small amounts in cubeb, dill and fennel oils. 

ASARONE 70-80% of calamus oil. In trace amounts in Asian carrot seed and clove bud oils. 

DILL APIOLE Up to 60% in Indian dill seed oil and in varying amounts in other parts and other species of dill. In various small amounts in fennel and carrot seed oils. 

MYRISTICIN In moderate amounts in dill, carrot, celery, fennel, mace and nutmeg (no more than 10% tops). Makes up about 40% of the oil of parsnip and can reach up to 50-60% of the oil of parsley leaves and seeds. Give nutmeg a rest folks It just don t have it when compared to parsley and parsnip. 

The iaterpretation of forensic toxicology (18) results is often challenging. Courts frequently ask if an amount of dmg detected ia a specimen could cause a specific type of behavior, ie, would someone be under the influence of a dmg at a specific concentration, would a particular dmg concentration cause diminished capacity, or was the dmg the cause of death In a random employee dmg testing case, a worker screened positive for opiates by EMIT and gc/ms analysis of the urine specimen showed low levels of morphine. Although one possibiUty was that the iadividual was a heroia user, a review of foods eaten ia the prior 24 hours suggested a more innocent cause a poppy-seed bagel. 

Soluble analogues of these difunctional initiators have been prepared either by addition of small amounts of weakly basic additives such as triethylamine (73) or anisole (74) which have relatively minor effects on diene microstmcture (37). Another method to solubilize these initiators is to use a seeding technique, whereby small amounts of diene monomer are added to form a hydrocarbon-soluble, oligomeric dilithium-initiating species (69,75). 

Fats and fatty oils). For the most part, oil is contained in the kernel or embryo of the seed, though it can also occur in the flesh of the ginkgo fmit and in the endosperm of coconut, palm, and pine nuts. Relative amounts of some fatty acids present in a few types of nuts are given in Table 5. Considerable variations in the percentages of fatty acids have also been reported in both pecan and peanut oils from a variety of sources. (Table 6).
