Sand dunes are found along the coasts of most of the large land
masses of the world. Because of their proximity to man and his
activities, the maritime sand dunes of Europe, particularly Germany,
France, Holland and Scandinavia, have the longest history of stabilization
activities and botanical investigation. There are...
This study traces the historical foundations of the concept of
constant ionic proportionality and the equation (Salinity [S%₀] = 1.805
Chlorinity [Cl%₀] + 0.030) which has been in general use in oceanography
since 1902 until 1969 and which is based upon this constancy,
The notion that the constituents present in...
Kinetics of cell division in the intestinal epithelial proliferative cells (cell nests) of the rough-skinned newt, Taricha granulosa, were studied using tritiated thymidine autoradiography and the mitotic arresting properties of colcemid. Percent labeled mitoses (PLM) curves were drawn from the autoradiographic data from two separate experiments in which the newts...
This study involved three separate experiments employing a total
of 29 horses and 4 rabbits. The purpose of these studies was to investigate
the use of various quantities and forms of ryegrass straw in horse
rations, and to determine the use of whole corn plant pellets as an alternative
roughage...
The R/V WECOMA cruise leg 6 emphasized the field work of the marine geology research program on "Patterns and processes of continental margin sedimentation." This program constitutes a mesoscale study of processes controlling hemipelagic sediment distribution and composition beneath the coastal upwelling, non-upwelling and pelagic regimes of the equatorial East...
Major and trace element analyses were made on biogenic carbonate,
silica, and fish debris and on authigenic philhipsite, micronodules, and
yellow and brown aggregates recovered from Bauer and Roggeveen Basin
metalliferous sediments. Phase components and the bulk samples were
analyzed by INAA and MS methods. Leachates and residues from ammonium...
Partly laminated sediments on the upper continental
slope (200-600 m) off central Peru contain a diverse assemblage
of fish debris, diatoms, and the remains of a variety
of other nektonic, planktic, and benthic organisms. Approximately
97 percent of the fish scales recovered from
the best preserved cores come from the...
