Preliminary study of radioactive limonite localities in Colorado, Utah, and Wyoming
T.G. Lovering, E.P. Beroni
1956, Trace Elements Investigations 427
Nine radioactive limonite localities of different types were sampled during the spring and fall of 1953 in an effort to establish criteria for differentiating limonite outcrops associated with uranium or thorium deposits from limonite outcrops not associated with such deposits. The samples were analyzed for uranium and thorium by standard...
Ground water in northeastern Louisville, Kentucky with reference to induced infiltration
M. I. Rorabaugh
1956, Water Supply Paper 1360-B
In cooperation with the city of Louisville, Ky., the U. S. Geological Survey made a detailed investigation during the period February 1945 to March 1947 of the ground-water resources of a 3-square-mile area along the Ohio River north-east of Louisville. Test drilling shows that the principal aquifer consists of about...
Ground-water geology of the coastal zone, Long Beach-Santa Ana area, California
J. F. Poland, A. M. Piper
1956, Water Supply Paper 1109
This paper is the first chapter of a comprehensive report on the ground-water features in the southern part of the coastal plain in Los Angeles and Orange Counties, Calif., with special reference to the effectiveness of the so-called coastal barrier--the Newport-Inglewood structural zone--in restraining landwar,-1 movement of saline water. The...

Preliminary report on the geology and deposits of monazite, thorite, and niobium-bearing rutile of the Mineral Hill district, Lemhi County, Idaho
Edward Peck Kaiser
1956, Open-File Report 56-69
Deposits of minerals containing niobium (columbium), thorium, and rare earths occur in the Mineral Hill district, 30 miles northwest of Salmon, Lemhi County, Idaho. Monazite, thorite, allanite, and niobium-bearing rutile form deposits in metamorphic limestone layers less than 8 feet thick. The known deposits are small, irregular, and typically located...

Life history of lake herring of Green Bay, Lake Michigan
Stanford H. Smith
1956, Fishery Bulletin (109) 87-138
Although the lake herring has been an important contributor to the commercial fish production of Green Bay, little has been known about it. This study is based on field observations and data from about 6,500 lake herring collected over the period 1948 to 1952. Relatively nonselective commercial pound nets...

Status of sea lamprey control
James W. Moffett
1956, Wisconsin Conservation Bulletin (21) 14-17
Four experiments involving 873 bob-white quail (Colinus virginianus) chicks were conducted at the Patuxent Research Refuge, Laurel, Maryland. A comparison was made of calcium: phosphorus ratios of 1:1, 15:1, 1%: 1, 2:1, 2+:1,and 2%: 1in diets with phosphorus levels of 0.52, 0.75, 1.00, and 1.25 percent. The results indicate that...

Aromatic fluorine compounds. VII. Replacement of aromatic -Cl and -NO2 groups by -F
G. C. Finger, C.W. Kruse
1956, Journal of the American Chemical Society (78) 6034-6037
Replacement of -Cl by -F in aryl chlorides with potassium fluoride has been extended from 2,4-dinitrochlorobenzene to less activated halides by the use of non-aqueous solvents, especially dimethylformamide (DMF) and dimethyl sulfoxide (DMSO). Also replacement of -NO2 by -F in substituted nitrobenzenes was studied in DMF. As a direct result...
Aromatic fluorine compounds. VI. Displacement of aryl fluorine in diazonium salts
G. C. Finger, R.E. Oesterling
1956, Journal of the American Chemical Society (78) 2593-2596
Several chlorofluorobenzenes have been isolated from the Schiemann synthesis of fluorobenzenes. These have been shown to be the products of two side reactions occurring during thermal decomposition of the dry benzenediazonium fluoborate salt containing coprecipitated sodium chloride, an unavoidable contaminant in large preparations involving the use of hydrochloric acid and...

Spectrophotometric study of the thorium-morin mixed-color system
M. H. Fletcher, R.G. Milkey
1956, Analytical Chemistry (28) 1402-1407
A spectrophotometric study was made of the thoriummorin reaction to evaluate the suitability of morin as a reagent for the determination of trace amounts of thorium. At pH 2, the equilibrium constant for the reaction is 1 x 106, and a single complex having a thorium-morin ratio of 1 to...
Thoron-tartaric acid systems for spectrophotometric determination of thorium
F. S. Grimaldi, Mary H. Fletcher
1956, Analytical Chemistry (28) 812-816
Thoron is commonly used for the spectrophotometric determination of thorium. An undesirable feature of its use is its high sensitivity to zirconium. This study describes the use of tartaric acid as a masking reagent for zirconium. Three tartaric acid-thoron systems, developed for the determination of thorium, differ with respect to...

Biology of the sea lamprey in its parasitic phase
Phillip S. Parker, Robert E. Lennon
1956, Research Report 44
The investigations conducted on sea lampreys in aquariums were concerned with the duration of the parasitic phase of life, feeding, growth, and the interrelations between predator and host fish. Observations on lampreys reared from metamorphosis to maturity were made at the Fish and Wildlife Service Laboratory at Hammond Bay,...
