Table I lists some (but not all) new members of the 1-hydroxytryptamine family and related 1-hydroxyindoles (9) produced via the tungstate method from 1999 through 2000.

Besides being a convenient preparation for ethyl -dimethyl-aminophenylacetate, the procedure for reductive alkylation can be generalized.4,5 Table I lists the results obtained by the submitters. [Pg.71]

To date, the females of more than 150 species of insects have been reported to produce a sex attractant or excitant for the male, and males of more than 50 species have been shown to produce such materials to attract or sexually excite the females (39). Table I lists insect pests of the order Lepidoptera in which the occurrence of sex attractants has been reported since 1960. In addition, investigators... [Pg.24]

The poisons most likely to be encountered in an ammonia plant are those originating in the C02-removal system which precedes the metha-nator. Carry-over of a small amount of liquid into the methanator, which is almost inevitable, is not normally serious. Plant malfunction, however, can sometimes result in large quantities of C02-removal liquor being pumped over the catalyst, and this can be very deleterious. Table I lists the effects of common C02-removal liquors on methanation catalyst activity. [Pg.87]

If only one counter can be purchased, then a gamma counter is the instrument of choice since most assays are now performed with gamma emitting isotopes. Table I lists the isotopes in common usage for competitive protein binding assays. [Pg.63]

Table I lists the concentrations of nitrosodimethylamine (NDMA) and nitrosodiethylamine (NDEA) in some of the tobacco products which had greater than 0.5% nitrate content. Tobacco with less than 0.5% nitrate content, such as Bright tobaccos, yielded NDMA, NDEA and nitrosopyrrolidine (NPYR) generally below 5 ppb. The relatively high concentrations of NDMA in fine cut tobaccos and in snuff are possibly of significance in the increased risk for oral cancer among snuff dippers who use these tobacco types repeatedly each day by placing a pinch of the product directly into the gingival buccal fold (6,7).

Table I lists the bond cleavage frequencies for PGII. G4 is exclusively split in 1-3 mode while reduced G4 was not hydrolysed. G5 is cleaved in the 1-4 and 2-3 mode at 67 % and 33 % respectively, while reduced G5 is only split into reduced G2 and G3. The reduced G6 is not cleaved in the 1-5 mode, while reduced G2 and reduced G3 are readily formed. The non-reduced G6 is cleaved in 1-5, 2-4 and 3-3 modes yielding equimolar product pairs as was also seen for the cleavage of G4 and G5. These data demonstrate that cleavage of the glycosidic bond occurs from the reducing end. Table I lists the bond cleavage frequencies for PGII.

Annex I listing is the prerequisite for the mutual recognition of authorizations between Member States, whereby one Member State is obliged to accept the evaluation and authorization prepared by another Member State in situations where the agricultural, plant health, and environmental (including climatic) conditions relevant to the use of the plant protection product are comparable in the regions concerned (Article 10 of the Directive). ... [Pg.16]

Critics of our analyses who claim that the trials are flawed implicitly assume that it is my task to prove that antidepressant drugs do not work. But where does the burden of proof lie Earlier in this chapter I listed a few of the substances that have been used medicinally over the centuries. Others include putrid meat, fly specks, human sweat, worms, spiders, furs and feathers. These treatments seemed to work in the past at least well enough for... [Pg.73]

Table I lists the molecular weights and viscoelastic properties for the precursors and selected polymers produced in reaction (34). It also contains the ceramic yields obtained on pyrolysis to 900°C and the composition of the ceramic product.

Each differential equation contains a flow term identified by Q/V (flow rate/reactor volume) and also a reaction term which can be identified by a rate of reaction or equilibrium constant (k, K, k ). These reaction and equilibrium constants are functions of temperature which, in this study, was fixed. The viscosity dependence of the equilibrium constant (relating reactive species to total polymer) shown in Equations 6 and 7 was observed experimentally and is known as the Trommsdorf effect (6). Table I lists values and units of all parameters in Equations 1-7. [Pg.188]

Table I lists some characteristic wave lengths from the work of Gregory (9). The calculations of f shown in Figure 2 are taken from the work of Clayfield and Lumb.(lO) By using these calculations one can determine the attractive energy per pair of particles at various separation distances, and determine for any particular value gf Aj2i> Xj, and radius (a) the critical value of H that makes U j 21= kT, where k is the Boltzmann constant and kT is the average vibrational energy of a pair of particles flocculated at separation distance H. If Uj2l is greater than -kT the particles will nearly always bounce apart on collision, but if it is less than -kT the particles tend to flocculate.

Table I lists the excited state lifetimes for 0s(phen)3 + at three temperatures. The striking result is the lack of any significant change in the LMCT statefs lifetime on going from 295 to 10 K. Table I also presents data on the effects of deuteration on the charge transfer state lifetimes of Os(bpy) 3 /3+ complexes. The lifetimes are lengthened, but only by factors of 2 and 2.5 respectively, for Os(bpy)33+ and 0s(bpy)3 +. Table I lists the excited state lifetimes for 0s(phen)3 + at three temperatures.

Table I lists a variety of organic nonlinear materials which have appeared in the literature their relative powder efficiencies, absorption cutoffs and /3 values (if available) are also provided. These materials are "typical" only in that they represent results from the few classes of organic compounds investigated to date, yet they are instructive in that one learns which molecular properties may be important. A few caveats are in order to avoid misinterpretation of the data in Table I. Except for compound 10 (19) all the powder efficiency and cutoff data are from our own measurements. Powder measurements were performed on ungraded samples using the Nd YAG output at 1.06/t as fundamental since powder efficiency is a function of particle size distribution and a variety of other factors (3) these values are only semiquantitative. The cutoff values are the wavelengths for which 10-4M solutions in ethanol (unless otherwise indicated) have no absorbance. The cutoff values will be similar to those found in crystal state except where intermolecular charge transfer is important in the crystal or the molecule is solvatochromic, this latter effect being quite common for cyanine dyes such as...
