Determination of piglets' rectal temperature and respiratory rate through skin surface temperature under climatic chamber conditions
In animal farming, an automatic and precise control of environmental conditions needs information from variables derived from the animals themselves, i.e. they act as biosensors. Rectal temperature (RT) and respiratory ...
Interplay between thermal and immune ecology: Effect of environmental temperature on insect immune response and energetic costs after an immune challenge
Although the study of thermoregulation in insects has shown that infected animals tend to prefer higher temperatures than healthy individuals, the immune response and energetic consequences of this preference remain ...
An environmental friendly dopant for the high-temperature shift catalysts
Seasonal variation in the thermal biology of a terrestrial toad, Rhinella icterica (Bufonidae), from the Brazilian Atlantic Forest
As ectotherms, amphibians may exhibit changes in their thermal biology associated with spatial and temporal environmental contingencies. However, our knowledge on how amphibian´s thermal biology responds to seasonal changes ...
Environmental effects on viscoelastic behavior of carbon fiber/PEKK thermoplastic composites
(Sage Publications Ltd, 2014-04-01)
In the last years, thermoplastic composites have been introduced as structural materials for high performance aerospace applications. However, these materials can present problems when exposed to moisture, temperature, and ...
Environmental effects on the accumulation of hydroxamic acids in wheat seedlings: The importance of plant growth rate
(Springer New York LLC, 1997)
The effects of temperature and photoperiod on accumulation of hydroxamic acids (Hx) in wheat (Triticum aestivum L.) seedlings were evaluated under laboratory conditions. Hx concentrations were significantly higher at higher ...
Photosynthetic responses to temperature in tropical lotic macroalgae
A comparative analysis of the photosynthetic responses to temperature (10-30°C) was carried out under short-term laboratory conditions by chlorophyll fluorescence and oxygen (O2) evolution. Ten lotic macroalgal species ...
Impact of environmental factors on neglected emerging arboviral diseases
(Public Library Science, 2017-09-01)
Background Brazil is a tropical country that is largely covered by rainforests and other natural ecosystems, which provide ideal conditions for the existence of many arboviruses. However, few analyses have examined the ...
