The thermal regime of a postulated descending lithospheric slab
is calculated. The gravity anomaly associated with such a structure
is large in amplitude and long in wavelengh. Observed free-air
gravity anomalies in the Pacific Northwest do not indicate a gravitational
effect due to a descending slab.
Two hypothetical compensation models...
Geophysical surveys in the Gulf of California provided
the data to construct contour maps of bathymetry, free-air
anomalies and total field magnetic anomalies for the area
north of 27° N. Major faults such as the Ballenas-
Salsipuedes, Tiburón, Guaymas, and the South Cerro Prieto
are clearly observable on these maps....
To assist in the assessment of the geothermal potential of north-central
California and to aid in defining the geologic transitions
between the physiographic provinces of the Klamath Range, the Cascade
Range, the Modoc Plateau, the Great Valley, and the Sierra Nevada
Range, personnel from the Geophysics Group in the College...
The respiratory tract is lined with a mucous blanket which is
motivated by a ciliated epithelium. This blanket includes a lower
serous layer of fluid through which the cilia beat and an upper viscid
layer into which particulates from the inhaled air are deposited.
The movement of the mucous blanket...
Seismic refraction measurements along two unreversed lines
indicate that the earth's crust is 26 km thick in southeastern Alaska
and 30 km thick along the Inside Passage of British Columbia. The
crust in southeastern Alaska, north of Dixon Entrance, consists of
a layer 9 km thick with a seismic velocity...
A free-air gravity anomaly map of the continental margin of
Peru between 12° and 18° S. Lat. shows a -110 to -220 mgl anomaly
associated with the Peru-Chile Trench, a -60 mgl anomaly over the
Pisco Basin on the continental shelf, and -120 mgl anomaly over the
Mollendo (or Arequipa)...
The (±) 8,9:13,14-diseco-norestradiol, a large ring hormone
analog, and its related derivatives, were prepared by a ring expansion
approach. The key step of this approach is the establishment of the
benzocyclododecenone system via the Caubere reaction. This step
not only provides a favorable ring size, it also sets the necessary...
