Thermoregulatory syndromes of two sympatric dung beetles with low energy costs
(Pergamon-Elsevier Science Ltd, 2019-10)
In heterotherm insects, endothermy implies a high energy cost due to the generation and regulation of body temperature during different activities such as flight, food location, fighting and even walking. We studied the ...
Stratosphere/troposphere joint variability in southern South America as estimated from a principal components analysis
(Springer Wien, 2017-06)
To understand how the tropopause annual evolution relates to the troposphere and lower stratosphere over southern South America, the study analyzes the joint behavior of single and double thermal tropopauses with the 500 ...
Evaluation of a liquid crystal based polarization modulator for a space mission thermal environment
(Elsevier B.V., 2017-10-15)
The Multi Element Telescope for Imaging and Spectroscopy (METIS) is one of the remote sensing instruments to be onboard the future NASA/ESA Solar Orbiter mission. The science nominal mission orbit will take the spacecraft ...
Measuring land surface temperature, near-infrared and short-wave infrared reflectance for estimation of water availability in vegetation
(Elsevier, 2021-01)
The vegetation water status is a crucial variable for modelling of drought impact, vegetation productivity and water fluxes. Methods for spatial estimation of this variable still need to be improved. The integration of ...
Full thermal-hydraulic and solar modeling to study low-cost solar collectors based on a single long LDPE hose
(Pergamon-Elsevier Science Ltd, 2017-06)
A comprehensive analysis of low-cost solar collectors based on a single long plastic LDPE hose resting on a roof and working by thermosiphon is performed. This lay-out involves two challenging issues, high hydraulic ...
On the thermal models for resistive random access memory circuit simulation
(MDPI AG, 2021-05)
Resistive Random Access Memories (RRAMs) are based on resistive switching (RS) operation and exhibit a set of technological features that make them ideal candidates for applications related to non-volatile memories, ...
Analytic modeling of parabolic trough solar thermal power plants
(Pergamon-Elsevier Science Ltd, 2017-07)
We derive, evaluate and validate comprehensive analytic modeling of the energy flows in parabolic trough solar thermal power plants. The analytic formulae are straightforward to implement and evaluate, relating to the heat ...
Thermal niche helps to explain the ability of dung beetles to exploit disturbed habitats
(Nature Publishing Group, 2020-08)
In terrestrial ecosystems, insects face a wide range of temperatures among habitats and time;consequently, the thermal niche is one of the main determinants of habitat selection and temporalpatterns of activity. The ...
Developmental thermal plasticity among Drosophila melanogaster populations
(Wiley, 2014-03)
Many biotic and abiotic variables influence the dispersal and distribution of organisms. Temperature has a major role in determining these patterns because it changes daily, seasonally and spatially, and these fluctuations ...
