Martian volcanism: Additional observations and evidence for pyroclastic activity
M. West
1974, Icarus (21) 1-11
Inspection of the Mariner 9 B-camera (resolution 100–200m) and A-camera (resolution 1–2km) photographs of Mars reveals numerous analogs of terrestrial and lunar volcanic features. In addition to the exceptionally large constructional features in the Tharsis region, many other large and small landforms present...
In vitro and in vivo efficacy of potentiated sulfonamide in control of furunculosis in salmonids
G. L. Bullock, H. M. Stuckey, D. Collis, R. L. Herman, G. Maestrone
1974, Journal of the Fisheries Research Board of Canada (31) 75-82
In vitro and in vivo efficacy of a potentiated sulffonamide, Ro5–0037, for inhibition of Aeromonas salmonicida, causative agent of fish furunculosis was determined. The components of the potentiated sulfonamide, sulfadimethoxine, and ormetoprim were tested alone and in combination. In vitro results showed that both sulfonamide-resistant and sensitive strains of A. salmonicida had greater sensitivity...

A revised list of reference samples of interest to geoscientists has been extended to include samples for the agronomist, the archaeologist and the environmentalist. In addition to the source from which standard samples may be obtained, references or pertinent notes for some samples are included.The number of rock reference samples...
Myxosoma cerebralis: Isolation and concentration from fish skeletal elements - Sequential enzymatic digestions and purification by differential centrifugation
M.E. Markiw, K. Wolf
1974, Journal of the Fisheries Research Board of Canada (31) 15-20
An effective sequential procedure for recovery of Myxosoma cerebralis spores from infected trout was developed, and quantification of spores was carried out at each step of release and concentration. Methods are described for fresh and frozen material. Effective concentration of from 1100- to 9000-fold and an estimated efficiency of recovery of about...
Geophysical evidence for the intersection of the St Paul, Cape Palmas and Grand Cess fracture zones with the continental margin of Liberia, West Africa
John C. Behrendt, J. Schlee, James M. Robb
1974, Nature (248) 324-326
PUBLISHED reconstructions of Gondwana continent1 (Fig. la) show a gap in fit near the junction of the Americas and Africa. To study this critical area, the Unitedgeo I made geophysical measurements and collected rock samples across the continental margin of Liberia (USGS-IDOE cruise leg 5) in November...
40Ar/39Ar age spectra of some undisturbed terrestrial samples
G. Brent Dalrymple, M. A. Lanphere
1974, Geochimica et Cosmochimica Acta (38) 715-738
40Ar/39Ar age spectra and 40Ar/36Ar vs 39Ar/36Ar isochrons were determined by incremental heating for 11 terrestrial rocks and minerals whose geology indicates that they represent essentially undisturbed systems. The samples include muscovite, biotite, hornblende, sanidine, plagioclase, dacite, diabase and basalt and range in age from...

A probe for sampling interstitial waters of stream sediments and bog soils
G.A. Nowlan, C. Carollo
1974, Journal of Geochemical Exploration (3) 199-205
A probe for sampling interstitial waters of stream sediments and bog soils is described. Samples can be obtained within a stratigraphic interval of 2–3 cm, to a depth of 60–80 cm, and with little or no contamination of the samples by sediment or...
Martian planetwide crater distributions: Implications for geologic history and surface processes
L.A. Soderblom, C.D. Condit, R.A. West, B.M. Herman, T. J. Kreidler
1974, Icarus (22) 239-263
Population-density maps of craters in three size ranges (0.6 to 1.2 km, 4 to 10 km, and >20 km in diameter) were compiled for most of Mars from Mariner 9 imagery. These data provide: historical records of the eolian processes (0.6 to 1.2 km craters); stratigraphic, relative, and absolute timescales...
Problems encountered in the use of neutron methods for elemental analysis on planetary surfaces
F. Senftle, P. Philbin, R. Moxham, G. Boynton, J. Trombka
1974, Nuclear Instruments and Methods (117) 435-443
From experimental studies of gamma rays from fast and thermal neutron reactions in hydrogeneous and non-hydrogeneous, semi-infinite samples and from Monte Carlo calculations on soil of a composition which might typically be encountered on planetary surfaces, it is found that gamma rays from...
Corynebacterial kidney disease of salmonids: Growth and serological studies on the causative bacterium
G. L. Bullock, H. M. Stuckey, P. K. Chen
1974, Applied Microbiology (28) 811-814
Comparative growth studies of 10 isolates of the Corynebacterium of salmonid kidney disease were quantified on four media. Greatest cell yield was obtained from Mueller-Hinton medium with 0.1% L-cysteine hydrochloride. Serological tests, in which rabbit antisera used against typical bacteria strains showed all to be antigenically homologous, provided a reliable method of...
Map showing areas serviced by public water-supply agencies in 1973 greater Pittsburgh region, southwestern Pennsylvania
Robert M. Beall
1974, Miscellaneous Field Studies Map 607
Urban water planning, development, and management are many sectored, costly efforts, subject to a multitude of controls and demands including those imposed by nature. One primary concern in development is for providing a dependable and safe water supply. In spite of a bountiful natural availability, the process of satisfying consumer...
Antiferromagnetic inclusions in lunar glass

1974, Earth and Planetary Science Letters (22) 85-90
The magnetic susceptibility of 11 glass spherules from the Apollo 15, 16, and 17 fines and two specimens of a relatively large glass spherical shell were studied as a function of temperature from room temperature to liquid helium temperatures. All but one...

Serological diagnosis of corynebacterial kidney disease of salmonids
P. K. Chen, G. L. Bullock, H. M. Stuckey, A.C. Bullock
1974, Journal of the Fisheries Research Board of Canada (31) 1939-1940
An immunodiffusion test is described which provides a rapid, sensitive, and definitive diagnosis of corynebacterial kidney disease of salmonid fishes. Specific precipitin lines are formed within 24 h when rabbit antiserum is reacted with kidney disease cell suspensions or internal tissue homogenates containing the specific bacterium. No precipitin lines are formed...
