Analysis of the Trends in Observed Extreme Temperatures in Mainland Chile Between 1966 and 2015 Using Different Indices
(Birkhauser Verlag AG, 2019)
Air temperature records provide strong evidence of change and variability in the climate system. The sensitivity of temperature to changes throughout the year renders it an ideal object of study when seeking to identify ...
Ambient temperature and stroke risk: Evidence supporting a short-term effect at a population level from acute environmental exposures
(Lippincott Williams and Wilkins, 2018)
Configurational temperature in constrained systems: The case of spin dynamics
(Institute of Physics Publishing, 2018)
© 2018 IOP Publishing Ltd. A general mathematical expression to estimate the temperature in computer simulations of constrained systems is obtained. Using a recently derived theorem which relates the ensemble average of ...
Prosopis chilensis is a plant highly tolerant to heat shock
At temperatures between 25 and 35°C, 100% of Prosopis chilensis seeds germinated within 24 h. At higher temperatures, the germination rate was reduced; at 50°C, seeds did not germinate. After germination at 25°C, the optimal ...
Preliminary Studies on Temperature Selection and Activity Cycles of Triatoma infestans and T. spinolai (Heteroptera: Reduviidae), Chilean Vectors of Chagas' Disease
(Entomological Society of America, 1997)
Preferred temperature and activity patterns of Triatoma infestans Klug and Triatoma spinolai Porter were studied, both are vectors of Chagas' disease in Chile. In the laboratory, 24 T. spinolai and 18 T. infestans were ...
Topoclimatic modeling for minimum temperature prediction at a regional scale in the Central Valley of Chile
(EDP Sciences, 1997)
Spring frost may strongly affect fruit production in the Central Valley of Chile. Minimum temperatures are spatially variable owing to topography and soil conditions. A methodology for forecasting minimum temperature at a ...
Microhabitat selection in the sand recluse spider (Sicarius thomisoides): the effect of rock size and temperature
(Taylor & Francis, 2017)
In spiders, temperature is considered an important environmental variable for microhabitat selection. In this study, we evaluated the effect of temperature and rock size on the presence of the sand recluse spider Sicarius ...
Physical and numerical modelling of the thermally induced wedging mechanism
(ICE Publishing, 2015)
Field observations and laboratory experiments show that temperature cycles can lead to wedging and accumulation of permanent displacements in several geosystems. The magnitude of these displacements depends on the geometric ...
Synergistic effect of copper and low temperature over Listeria monocytogenes
The capacity to grow at low temperatures has allowed Listeria monocytogenes to become one of the primary food pathogens to date, representing a major public health problem worldwide. Several works have described the ...
Modulating factors of the energetic effectiveness of huddling in small mammals
(Polish Academy of Sciences, 1998)
Huddling is effective in decreasing metabolic rate permitting energy saving. However, this decrease varies among different species depending on physical, physiological and behavioral characteristics of the huddled individuals. ...
