Thermal treatment effects on phase transitions in P(VDF-TrFE)
(1999-12-01)
Differential scanning calorimetry (DSC) studies were performed for 60/40 P(VDF-TrFE). The results not only confirm the importance of thermal history but also show that the samples with various configurations in terms of ...
Short-term predicted extinction of Andean populations of the lizard Stenocercus guentheri (Iguanidae: Tropidurinae)
(PUCE, 2015)
We studied the thermal physiology of the Andean lizard Stenocercus guentheri in
order to evaluate the possible effects of global warming on this species. We determined the
preferred body temperature (Tpref), critical ...
Thermochronology of the South American platform in the state of São Paulo, Brazil, through apatite fission tracks
(Elsevier B.V., 2005-12-01)
The fission-track method (FTM) in apatite was applied to 45 samples collected in the Serra da Mantiqueira (Mantiqueira mountain range), the Serra do Mar (Mar mountain range), regions next to these mountain ranges and the ...
Projected length annealing of etched Sm-152 ion tracks in apatite
(Elsevier Science BvAmsterdamHolanda, 2012)
Divergence in morphometric and life history traits in two thermally contrasting Andean populations of Rhinella spinulosa (Anura: Bufonidae)
(2009)
(1)We studied the variation in characters of two Andean populations of Rhinella spinulosa with different larval thermal regimes as a function of geographic origin and temperature.(2)In both populations, survival and growth ...
Influence of glass forming histories on the structural and thermal properties of tellurite glasses

THERMAL-HISTORY-DEPENDENT TRANSITION IN PRESSED PELLETS OF CLO4(-)-DOPED POLY(3-METHYLTHIOPHENE)
(American Physical Soc, 1994-08-01)
Electron-spin-resonance and dc conductivity data show a thermal-history-dependent transition at 240 K in pressed pellets of ClO4--doped poly(3-methylthiophene) (P3MT). We discuss the possibility of this transition to be a ...
Thermal-history-dependent transition in pressed pellets of ClO4 - Doped poly(3-methylthiophene)
(1994-01-01)
Electron-spin-resonance and dc conductivity data show a thermal-history-dependent transition at 240 K in pressed pellets of ClO4 - doped poly(3-methylthiophene) (P3MT). We discuss the possibility of this transition to be ...
