Suggestions for reduction of natural mortality in fish populations
S. F. Snieszko
1958, Transactions of the American Fisheries Society (87) 380-385
Illness, in fish as well as in other animals, when caused by an infectious disease, is often not the result of infection with pathogens alone. In many cases the pathogens and hosts can exist side by side without development of disease symptoms. Such symptoms, with resulting illness or death,...
A combined deamination and nitro reduction method for nitroanilines
G. C. Finger, R.H. White
1958, Journal of Organic Chemistry (23) 1612-1613
The hypophosphorous acid-cuprous oxide deamination method on nitroanilines has been modified so that the nitro compounds which are formed are reduced in turn by cuprous oxide to the corresponding amines. Over-all yields of 55-65% are reported for three halogenated nitroanilines....
The water, deuterium, gas and uranium content of tektites
I. Friedman
1958, Geochimica et Cosmochimica Acta (14) 316-324
The water content, deuterium concentration of the water, total gas and uranium contents were determined on tektite samples and other glass samples from Texas, Australia, Philippine Islands, Java, French Indo-China, Czechoslovakia, Libyan Desert, Billiton Island, Thailand, French West Africa, Peru, and New Mexico. The water content ranges from 0.24 per...
Biogeochemistry of the rare-earth elements with particular reference to hickory trees
W. O. Robinson, H. Bastron, K. J. Murata
1958, Geochimica et Cosmochimica Acta (14) 55-67
Hickory trees concentrate the rare-earth elements in their leaves to a phenomenal degree and may contain as much as 2300 p.p.m. of total rare earths based on the dry weight of the leaves. The average proportions of the individual elements (atomic percent of the total rare-earth elements) in the leaves...
Role of clay minerals in the transportation of iron
D. Carroll
1958, Geochimica et Cosmochimica Acta (14) 1-28
The clay minerals have iron associated with them in several ways:1.(1) as an essential constituent2.(2) as a minor constituent within the crystal lattice where it is in isomorphous substitution and3.(3) as iron oxide on the surface of the mineral platelets. Nontronite, “hydromica,” some...

Retention of lead during oxidative ashing of selected naturally occurring carbonaceous substances
F. Cuttitta, J.J. Warr Jr.
1958, Geochimica et Cosmochimica Acta (13) 256-259
The amount of lead retained in the ash of lead-bearing carbonaceous material is essentially independent of the method of ashing. Samples containing lead in the range of 0.00X to 0.X per cent were ashed by ignition in a high-oxygen atmosphere and were also wet-ashed. The lead in the ash was...

Isolation and identification of an ester from a crude oil
H.F. Phillips, Irving A. Breger
1958, Geochimica et Cosmochimica Acta (15) 51-56
A dioctylphthalate has been isolated from a crude oil by means of adsorption column chromatography. The ester was identified by means of elemental analysis, refractive index, and its infra-red absorption spectrum. Saponification of the isolate and examination of the resultant alcohol by means of infrared absorption spectra led to the...

Spectrochemical method for the determination of selenium
C. L. Waring, H.W. Worthing, K.V. Hazel
1958, Analytical Chemistry (30) 1504-1506
Selenium can be determined in pyrite, chalcocite, and marcasite by a simple and rapid spectrochemical method that requires no complicated arrangement of spectrographic equipment or chemical pretreatment of samples. Advantage is taken of the new short wave length radiation plates (Eastman) and the addition of copper oxide to enhance the...
The deuterium content of water in some volcanic glasses
I. Friedman, R. L. Smith
1958, Geochimica et Cosmochimica Acta (15) 218-228
The deuterium-hydrogen composition (relative to Lake Michigan water = 0.0) of water extractsd from coexisting perlite and obsidian from eleven different localities was determined. The water content of the obsidians is generally from 0.09 to 0.29 per cent by weight, though two samples from near Olancha, California, contain about 0.92...
Determination of thorium in the parts per million range in rocks
H. Levine, F. S. Grimaldi
1958, Geochimica et Cosmochimica Acta (14) 93-97
A procedure is presented for the determination of thorium in the concentration range of 0·2 to 10 parts per million ThO2 in felsic or mafic rocks. Thorium is extracted by mesityl oxide and purified by iodate precipitation from nitric acid medium containing tartaric acid and hydrogen peroxide. The thorium is determined...
Dithizone method for determination of lead in monazite
R. A. Powell, C. A. Kinser
1958, Analytical Chemistry (30) 1139-1141
In the determination of lead in monazite-to be used as the basis for geologic age measurements-it was necessary to eliminate interferences due to the presence of phosphates of thorium and the rare earth metals. The method involves attacking the monazite samples with hot, concentrated sulfuric acid, then taking them up...
