Subduction Of The Caribbean Plate And Basement Uplifts In The Overriding South American Plate, James N. Kellogg, William E. Bonini May 1982

Subduction Of The Caribbean Plate And Basement Uplifts In The Overriding South American Plate, James N. Kellogg, William E. Bonini

James N Kellogg

Abstract. The new tectonic interpretations presented in this paper are based on geologic field mapping and gravity data supplemented by well logs, seismic profiles, and radiometric and earthquake data. The present Caribbean-South American plate boundary is the South Caribbean marginal fault, where subduction is indicated by folding and thrusting in the deformed belt and a seismic zone that dips 30o to the southeast and terminates 200 km below the Maracaibo Basin. The Caribbean-South American convergence rate is estimated as 1.9 +_. 0.3 cm/yr on the basis of the 390-km length of the seismic zone and a thermal equilibration time of …

Path-Integrals And The Wkb Approximation, Br Holstein, Ar Swift Dec 1981

Path-Integrals And The Wkb Approximation, Br Holstein, Ar Swift

Barry R Holstein

The WKB approximation is demonstrated to be formally identical to the semiclassical limit of the Feynman path integral propagator. In the limit that the path integral propagator is dominated by the classical particle trajectory, it is identical to the propagator calculated directly from WKB wave functions in the stationary phase approximation.


Effects Of Earthquake On Traditional Houses Of Kathmandu, Bhishna Bajracharya Dec 1981

Effects Of Earthquake On Traditional Houses Of Kathmandu, Bhishna Bajracharya

Bhishna Bajracharya

The paper explains some of the earthquake resistance measures in traditional houses of Kathmandu, Nepal. They include symmetry in design of buildings, double framing of openings and system of wooden wedges to secure timber joists with walls, all of which can help reduce earthquake effects. Based on information from secondary sources, the paper also discusses the causes of  extensive damage in Kathmandu Valley after the major earthquake of 1934 and argues the need for the design against roof collapse to minimize the loss of lives during earthquakes in Nepal.

Cluster Analysis To Determine Headache Types, Paula Diehr Dec 1981

Cluster Analysis To Determine Headache Types, Paula Diehr

Paula Diehr

Cluster analysis was used to separate 726 headache patients into clusters of patients with similar symptoms. This was done to answer two questions: what "naturally occurring' groups of patients can be found? And how do these groups correspond to traditional headache types? When only two clusters were required, the best two clusters were tension and migraine-like. However, eight clusters could also be distinguished, and the migraine group then became very small. The clusters were tested for clinical interpretability by having 12 physicians name and prescribe treatment for the clusters. The suggested treatment was similar to what patients had actually received …
