Thorium has a wide distribution in nature and is present as a tetravalent oxide in a large number of minerals in minor or trace amounts. Thorium is significantly more common in nature than uranium, having an average content in the earth s cmst of approximately 10 ppm. By comparison, Pb is approximately 16 ppm. Thorium has a seawater concentration of <0.5 x 10 . Thorium refined from ores free of uranium would be almost... 

For a lower range of motors, say up to a frame size of 355, the silicon steel normally used for stator and rotor core laminations is universally 0.5-0.65 mm thick and possesses a high content of silicon for achieving better electromagnetic properties. The average content of silicon in such sheets is of the order of 1.3-0.8% and a core loss of roughly 2.3-3.6 W/kg, determined al a flux density of I W[ym and a frequency of 50 Hz. For medium-sized motors, in frames 400-710, silicon steel with a still better content of silicon, of the order of 1.3-1.8% having lower losses of the order of 2.3-1.8 W/kg is prefeired, with a thickness of lamination of 0.5-0.35 mm. 

The average contents of most of the elements except Zn and Ba of the Nishikurosawa are same in orders to NASC. 

Average contents of minor elements of the Onnagawa are mostly lower than Average Shale. However, Cu, Zn, Mo, Ba and U contents are anomalously high compared with Average Shale. 

Average contents of minor elements of the Funakawa are lower than NASC which is due to slightly higher Si02 content of the Funakawa.

In general electrum is rare, but it is found in some deposits such as the Shimokawa, Besshi, and Yanahara (Urashima, 1974). A detailed study on the mode of occurrence of electrum has been carried out only on the Shimokawa deposit (Maeda et al., 1981). Flectrum occurs in compact massive or banded ores in the upper horizon. This mineral is intimately associated with sphalerite and pyrrhotite. Analytical data on electrum are available only from the Shimokawa (Maeda et al., 1981). The Ag content ranges from 22.2 to 71.6 atomic %, but average content is ca. 30 atomic %. This variation range is... 

A method described by Florence and Farrer [584] separated tin from its associated lead by distillation from an aqueous sulfuric acid medium into which the vapour from boiling 50% hydrobromic acid is passed. The distillate provides an ideal supporting electrolyte for the determination of tin (II) (produced by reduction with hydrazinium hydroxide) by anodic stripping at a rotating vitreous-carbon electrode in the presence of codeposited mercury [585,586]. The tin is deposited at -0.70 V versus the SCE for 5 minutes, and then stripped at -0.50 V during a sweep from -0.70 V to -0.45 V at 5 V per minute. Tin in seawater is coprecipitated on ferric hydroxide, and the precipitate is then dissolved in the aqueous sulfuric acid, and subjected to the above procedure. The average content for Pacific coastal waters was found to be 0.58 xg/l.

Table 14. The comparative estimation of average content of trace metals in surface waters of Swamp ecosystems, pg/L (after Shvartsev, 1999 and Dobrovolsky, 1994).

We can see that for zinc the average content in surface waters of various ecosystems is increasing in as follows Forest < Forest Steppe < Steppe. Similar peculiarities are shown for strontium. However, for some metals this tendency is not confirmed or even we can see the opposite direction, for instance for manganese, whose content is higher in waters of Forest ecosystems. 

According to Stein (S8), 1761-2459 mg of amino adds appears in 24 hours urine collection from normal subjects after its acid hydrolysis. The estimations performed by Muting (M4) showed that the average content of amino acids in 24-hour specimens of urine derived from 20 normal males and the same number of normal female subjects was 2221 and 2288 mg, respectively. The results of these two authors do not, however, represent exclusively the amount of peptide-bound amino acids, but rather the whole of these compounds liberated as a result of the acid...

Nickel is a silver-white, lustrous, hard, malleable, ductile, ferromagnetic metal that is relatively resistant to corrosion and is a fair conductor of heat and electricity. Nickel is a ubiquitous trace metal that occurs in soil, water, air, and in the biosphere. The average content in the earth s crust is about 0.008%. Nickel ore deposits are accumulations of nickel sulfide minerals (mostly pentlandite) and laterites. Nickel exists in five major forms elemental nickel and its alloys inorganic, water-soluble compounds (e.g., nickel chloride, nickel sulfate, and nickel nitrate) inorganic, water-insoluble compounds (e.g., nickel carbonate, nickel sulfide, and nickel oxide) organic, water-insoluble compounds and nickel carbonyl Ni(CO). ... 

In batch reactions, where the yield is high and no additional monomer is added, at the end of the reaction the average content of each monomer imit in the total copolymer formed will necessarily be directly related to the initial ratio of the two monomers. Thus, the copolymer content will vary depending on when the particular chains are formed but the final overall product will have an average of units in it reflective of the initial monomer concentrations. 

The helix contents of five peptide fragments from the protein thermolysin have been determined by CD and NMR in both water and 30% TFE. 85 The helix content was obtained from CD by the method of Chen et a I.162 and the NMR method utilized chemical shifts. 84 Four of the five peptides correspond to helical regions in the intact protein, and one corresponds to an Q-loop. 86 The rms difference between CD and NMR helix contents for the five peptides under the two conditions is 7.5%. One peptide shows the largest deviations (0 vs 13% in water, 45 vs 62% in 30% TFE). If it is excluded, the rms deviation decreases to 4%. The peptide showing the largest deviation, residues 258-276 from the thermolysin sequence, has two Tyr and one Phe (with the Phe adjacent to one of the Tyr in the sequence), and therefore it has an above-average content of aromatic amino acids, which can perturb both the CD spectrum and NMR chemical shifts. Of the other four peptides, three have a single aromatic residue and the fourth has two aromatics. 

The atmospheric gas contribution to the fluids discharged after re-injection is shown in Fig. 7, where the relative contents of N2, He, and Ar for samples collected before and after re-injection are plotted. Injected and/or infiltrated waters previously equilibrated with the atmosphere are expected to introduce 2.4 x 10-4 mmol/mol of Ar into the deep reservoir (Mazor 1978). This value is very similar to the average content of the fluid produced before re-injection (1.6 x 10-4, Scandiffio et al. 1995). However, the two endmembers differ in N2 contents in the injectate, the theoretical N2/Ar ratios are between 84 and 38 (values for air and air-saturated groundwater, respectively), whereas in the original fluid, this ratio is about 800 (Scandiffio et al. 1995). 

Di(2-ethylhexyl) phthalate was detected in whole blood at levels ranging from 16.8 to 46.1 ig/mL [mg/L] and in packed cells at levels ranging from 32.6 to 55.5 p,g/mL [mg/L] in PVC blood bags stored at 5 °C. These levels increased with storage. The average content was 6.7 4.6 ig/mL in cryoprecipitate and 7.4 2.8 Xg/mL in fresh frozen plasma. Both values were independent of the storage period (Sasakawa Mitomi, 1978).
