Coupled vibrations of rectangular buildings subjected to normally-incident random wind loads
E. Safak, D.A. Foutch
1987, Journal of Wind Engineering and Industrial Aerodynamics (26) 129-148
A method for analyzing the three-directional coupled dynamic response of wind-excited buildings is presented. The method is based on a random vibration concept and is parallel to those currently used for analyzing alongwind response. Only the buildings with rectangular cross-section and normally-incident wind are considered. The alongwind pressures and...

Pure shear and simple shear calcite textures. Comparison of experimental, theoretical and natural data
H.-R. Wenk, T. Takeshita, E. Bechler, B.G. Erskine, S. Matthies
1987, Journal of Structural Geology (9) 731-745
The pattern of lattice preferred orientation (texture) in deformed rocks is an expression of the strain path and the acting deformation mechanisms. A first indication about the strain path is given by the symmetry of pole figures: coaxial deformation produces orthorhombic pole figures, while non-coaxial deformation yields monoclinic or triclinic...

Diagenetic palaeotemperatures from aqueous fluid inclusions: re-equilibration of inclusions in carbonate cements by burial heating
R.C. Burruss
1987, Mineralogical Magazine (51) 477-481
Diagenetic palaeotemperatures determined from aqueous fluid inclusions can be affected by re-equilibration during burial heating. Calculations based on the observed behaviour of inclusions in fluorite under external confining pressure allows prediction of the temperatures and depths of burial necessary to initiate re-equilibration of aqueous inclusions in the common size range...

1987, Conference Paper, The influence of climate change and climatic variability on the hydrologic regime and water resources (Proceedings of the Vancouver Symposium, August 1987), IAHS Publication no. 168
The strong north-south gradient in precipitation along the West Coast makes this region an interesting laboratory for studying the influence of climate on runoff variability in general and riverine chemistry in particular. Interannual fluctuations in large-scale atmospheric circulation and associated precipitation and runoff can produce major disruptions in the "average"...

Benthic foraminifera of the Panamanian Province: distribution and origins.
R.W. Crouch, C. W. Poag
1987, Journal of Foraminiferal Research (17) 153-176
Two hundred twenty-nine species of benthic foraminifera have been identified from 96 stations representing 33 localities on the eastern Pacific inner continental shelf, ranging from southern Peru to northern Baja California. Their distributions mark nearshore provincial boundaries that are nearly identical with those previously documented from the distribution of ostracodes...
Estimating generalized skew of the log-Pearson Type III distribution for annual peak floods in Illinois
Kevin A. Oberg, Dean M. Mades
1987, Water-Resources Investigations Report 86-4008
Four techniques for estimating generalized skew in Illinois were evaluated: (1) a generalized skew map of the US; (2) an isoline map; (3) a prediction equation; and (4) a regional-mean skew. Peak-flow records at 730 gaging stations having 10 or more annual peaks were selected for computing station skews. Station...
Direct comparison of kinetic and local equilibrium formulations for solute transport affected by surface reactions
Jean M. Bahr, Jacob Rubin
1987, Water Resources Research (23) 438-452
Modeling transport of reacting solutes in porous media often requires a choice between models based on the local equilibrium assumption (LEA) and models involving reaction kinetics. Direct comparison of the mathematical formulations for these two types of transport models can aid in this choice. For cases of transport affected by...

1987, Science (238) 757-761
Proposed further developments on Alaska's Arctic Coastal Plain raise questions about cumulative effects on arctic tundra ecosystems of development of multiple large oil fields. Maps of historical changes to the Prudhoe Bay Oil Field show indirect impacts can lag behind planned developments by many years and the total area eventually...
Maestrichtian benthic foraminifers from Ocean Point, North Slope, Alaska ( USA).
K. McDougall
1987, Journal of Foraminiferal Research (17) 344-366
Previous studies of fauna and flora from Ocean Point, Alaska, have suggested ages ranging from Campanian to early Eocene and that these assemblages are either highly endemic or commonplace. I demonstrate that the moderately abundant benthic foraminifers constitute early Maestrichtian boreal assemblages common to Canada and northern Europe. Paleoenvironmental analysis...
