Use of high-temperature and high humidity to test the adhesion of sputtered copper to a polyimide surface-modified by an AC Nitrogen Glow-Discharge
(Brill (VSP): Journal of Adhesion Science and Technology, 1995)
We have used an extreme environmental stress test to study the adhesion of a thin sputtered copper film (0.5 mu m) to flexible polyimide (PI) substrates between 25 and 125 mu m thick. The polyimide types include Kapton ...
Morphological texture-based maximum-likelihood pixel classification bbased on local granulometric moments
(Elsevier Science B.V., Amsterdam, 1992-10)
Morphological granulometries are one-parameter filter sequences that monotonically decrease image area. A size distribution is generated by measuring the residual area after each iteration of the filter sequence. Normalization ...
Prey-handling and the evolutionary ecology of sand-swimming lizards (Lerista?: Scincidae)
(Springer: Oecologia, 1997-10)
Fossorial lizards differ in morphology from their surface-dwelling relatives. The Australian sphenomorphine skink genus Ctenotus consists of surface-dwelling species, and is closely related to the genus Lerista, which ...
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 ...

Revelations: the analysis and synthesis of images
Observer variability in metameric color matches using color reproduction media
(Wiley InterScience: Color Research & Application, 1998-12-06)
Standard color-matching functions are designed to represent the mean color-matching response of the population of human observers with normal color vision. When using these functions, two questions arise. Are they an ...
Ontogenetic change in blood oxygen capacity and maximum activity in garter snakes (Thamnophis sirtalis)
(Springer: Journal of Comparative Physiology B: Biochemical, Systemic, and Environmental Physiology, 1977-01)
There is an ontogenetic increase in the time that garter snakes (Thamnophis s. sirtalis) can maintain maximum activity at 25°C. Newborn snakes are exhausted by 3–5 min of activity while adults can be active for 20–25 min. ...
Physiological basis of habitat partitioning in Jamaican Eleutherodactylus
(Springer: Oecologia, 1977-12)
Rate of evaporation, resistance to drying, temperature selection, and critical thermal maximum were measured for Jamaican Eleutherodactylus acclimated to 20° C and a 12:12 L:D photoperiod. Two introduced species, E. ...
