Post-metamorphic change in activity metabolism of anurans in relation to life history
(Springer: Oecologia, 1984-12)
Newly-metamorphosed individuals of some species of frogs and toads differ from adults in behavior, ecology, and physiology. These differences may be related to broader patterns of the life histories of different species ...
Response to simultaneous dehydration and thermal stress in three species of Puerto Rican frogs
(Springer: Journal of Comparative Physiology B: Biochemical, Systemic, and Environmental Physiology, 1984-11)
The response to simultaneous temperature and dehydration stress was examined in three species of Puerto Rican frogs. Eleutherodactylus antillensis is found primarily in hot, arid grasslands at low altitudes. Eleutherodactylus ...
Correction of thermal imagery for atmospheric effects using aircraft measurement and atmospheric modeling techniques
(Optical Society of America (OSA), 1986-08)
Airborne measurements of atmospheric-path transmission and atmospheric-path (upwelled) radiance in the 8-14-gm band were obtained by applying a multiple altitude and a dual-view angle calibration technique to thermal IR ...

Role of solvent reorganization dynamics in electron-transfer processes. Theory-experiment comparisons for electrochemical and homogeneous electron exchange involving metallocene redox couples
(The American Chemical Society: Journal of Physical Chemistry, 1985-06-20)
Electrochemical rate constants and activation parameters are reported for the electron exchange of five metallocene couples and bis(benzene)chromium(I/0) in eight solvents at mercury electrodes. The solvents (acetonitrile, ...
Reliability of standard rate constants for rapid electrochemical reactions
(The American Chemical Society: Analytical Chemistry, 1984-07)
A method is outlined for testing the reliability of standard rate constants, k^s, for rapid electrode reactions evaluated by using electrochemical perturbation techniques. This entails monitoring the response of the apparent ...
Reaction of 2,4-dinitrobenzenesulfenyl chloride with quadricyclene
(The American Chemical Society: The Journal of Organic Chemistry, 1982-04-09)
The treatment of quadricyclene with 2,4-dinitrobenzenesulfenyl chloride has been reinvestigated and chloro adducts 1-A and 2b-A as well as acetates 4a-A, 4b-A, 6, and 7 have been obtained. Establishing 2b-A with endo-chloride ...
Critical behavior of a microemulsion studied by small-angle neutron scattering
(American Physical Society, 1983-07)
The critical behavior of a three-component water-in-oil microemulsion was studied by small-angle neutron scattering. Intensity spectra were analyzed by the treatment of critical scattering as arising from concentration ...
Attractive interactions in micelles and microemulsions
(American Physical Society, 1984-08-06)
We have used small-angle neutron scattering to study surfactant interactions in an inverted micellar and a related microemulsions system. The structure-factor fits imply an attractive interaction between micelles with a ...
Structure of Dense Sodium Di-2-Ethylsulfosuccinate/D2O/Decane Microemulsions
(American Physical Society, 1984-08-27)
Small-angle neutron scattering is used to investigate the structure of single-phase AOT (sodium di-2-ethylsulfosuccinate)/D2O/decane microemulsions containing equal volumes of water and oil and a variable concentration of ...
