Determination of niobium in the parts per million range in rocks
F. S. Grimaldi
1960, Analytical Chemistry (32) 119-121
A modified niobium thiocyanate spectrophotometric procedure relatively insensitive to titanium interference is presented. Elements such as tungsten, molybdenum, vanadium, and rhenium, which seriously interfere in the spectrophotometric determination of niobium, are separated by simple sodium hydroxide fusion and leach; iron and magnesium are used as carriers for the niobium. Tolerance...

Collection and preservation of fish and other materials exposed to pesticides
Oliver B. Cope
1960, Progressive Fish-Culturist (22) 103-108
The effects of pesticides on fish have become improtant to fish conservation since World War II, when DDT first came into common use. With the development of other potent insecticides and the increasing use of massive dosages in more recent years, the threat to fish and fish foods has increased....
Equivalent weight of humic acid from peat
A. M. Pommer, Irving A. Breger
1960, Geochimica et Cosmochimica Acta (20) 45-50
By means of discontinuous titration, the equivalent weight of humic acid isolated from a peat was found to increase from 144 to 183 between the third and fifty-second day after the humic acid was dissolved. Infra-red studies showed that the material had probably condensed with loss of carbonyl groups....
Theoretical stusy of the reaction between 2,2',4' - trihydroxyazobenzene-5-sulfonic acid and zirconium
Mary H. Fletcher
1960, Analytical Chemistry (32) 1827-1836
Zirconium reacts with 2,2',4'-trihydroxyazobenzene-5-sulfonic acid in acid solutions to Form two complexes in which the ratios of dye to zirconium are 1 to 1 and 2 to 1. Both complexes are true chelates, with zirconium acting as a bridge between the two orthohydroxy dye groups. Apparent equilibrium constants for the...

The bottom fauna of Lake Huron
Howard D. Teter
1960, Transactions of the American Fisheries Society (89) 193-197
The examination of 63 bottom samples, collected in Lake Huron in 1952 and 1956, revealed that Pontoporeia affinis was the dominant organism in both deep and shallow water. The next most abundant organisms in deep water were oligochaetes, fingernail clams, and midge larvae. Midge larvae were more numerous than either...

Lake Erie walleyes--again on the upswing?
Charles P. Seldon, Harry D. Van Meter
1960, Ohio Conservation Bulletin (24) 5-7
SUMMARY The effect of DDT dust on wildlife was studied at Camp Bullis, Bexar County, Texas, in the summer of 1947. Studies were made on a 206.6 acre plot that was treated with DDT for experimental control of the Lone Star tick (Amblyomrna americanum). A dust consisting...
A primer on water

Releasing effects in flame photometry. Determination of calcium
J. I. Dinnin
1960, Analytical Chemistry (32) 1475-1480
Strontium, lanthanum, neodymium, samarium, and yttrium completely release the flame emission of calcium from the depressive effects of sulfate, phosphate, and aluminate. Magnesium, beryllium, barium, and scandium release most of the calcium emission. These cations, when present in high concentration, preferentially form compounds with the depressing anions when the solution...
Magnetic susceptibility of tetragonal titanium dioxide
F. E. Senftle, T. Pankey, F. A. Grant
1960, Physical Review (120) 820-825
Careful measurements have been made of the magnetic susceptibility of the rutile and anatase crystalline forms of titanium dioxide. The magnetic susceptibility of a single crystal of high-purity rutile was found to be (0.067±0.0015)×<span id="MJXc-Node-6"...
Age and growth of the whitefish Coregonus clupeaformis, of Munising Bay, Lake Superior
Thomas A. Edsall
1960, Transactions of the American Fisheries Society (89) 323-332
This study is based on a sample of 415 whitefish collected in 1953 from an unexploited population in Munising Bay, Lake Superior. Gill-net and trawl catches had different length-frequency distributions and age compositions, but estimates of growth from the two catches were very similar. The body-scale relation is...

The vertical migration of Mysis relicta in Lakes Huron and Michigan
Alfred M. Beeton
1960, Journal of the Fisheries Research Board of Canada (17) 517-539
During the day Mysis relicta could be taken only near the bottom of Lakes Huron and Michigan. In the evening they migrated into the overlying strata as the surface light intensity decreased from 15 to 1 foot-candles. Frequently the mysids migrated through the metalimnion when first ascending, but later in the night...
Effect of FeS on the unit cell edge of sphalerite, a revision
Brian J. Skinner, P. B. Barton Jr., G. Kullerud
1959, Economic Geology (54) 1040-1046
Redeterminations of the relation between the composition and unit-cell size of Fe-bearing sphalerites, necessitated because of partial oxidation of the FeS sample used in earlier measurements, are presented. It is noted that the Fe-ZnS solvus curve may also require revision and should be used with caution, particularly for temperature determinations...
