Systematic investigation of the link between enzyme catalysis and cold adaptation

eLife, 2022
Cold temperature is prevalent across the biosphere and slows the rates of chemical reactions. Increased catalysis has been predicted to be a dominant adaptive trait of enzymes to reduced temperature, and this expectation has informed physical models for ...

Unsteady temperature, heat transfer rate and HTF outlet temperature variation during charging of latent thermal energy storage unit

Revue des Énergies Renouvelables, 2019
This work reports a detailed numerical study that is aimed to determine the variation of the three principal parameters, temperature of two phase change materials (PCMs), heat transfer rate and heat transfer fluid (HTF) outlet temperature, during ...

Temperature lapse rate estimation and snowmelt runoff simulation in a high-altitude basin

Scientific Reports, 2022
As a key parameter of hydrological process modeling, the near-surface air temperature lapse rate reflects the vertical changes in air temperature characteristics in alpine basins but often lacks the support of sufficient ground observation data.

Effect of body material and temperature variation on the performance of the time delay pyrotechnic compositions

Defence Technology, 2018
Significance of body material and temperature variation on burning time and burning rate of Si/PbO/Pb3O4/FG and B/BaCrO4/FG pyrotechnic delay compositions were experimentally studied. Brass and stainless steel were used as delay body materials.

Nocturnal plant respiration is under strong non-temperature control

Nature Communications, 2022
Plant respiration at night is assumed to be temperature-controlled. Here, the authors show that temperature controls less than half of the variation in leaf respiration rate at night, and demonstrate how to account for such nocturnal variation in ...

Ignoring temperature variation leads to underestimation of the temperature sensitivity of plant litter decomposition

Ecosphere, 2020
The majority of terrestrial net primary production decomposes, fueling detrital food webs and converting dead plant carbon to atmospheric CO2. There is considerable interest in determining the sensitivity of this process to climate warming.

Improved multivariable reasoning control method for carbon content control of argon–oxygen refining ferrochrome

AIP Advances, 2022
In order to control the end-point carbon content in the process of argon–oxygen refining ferrochromium alloys, according to the mechanism model of the oxygen supply rate and carbon content variation, the mechanism model of the argon supply rate and ...

Heart rate sensor validation and seasonal and diurnal variation of body temperature and heart rate in domestic sheep

Veterinary and Animal Science, 2019
Advantages of low input livestock production on large pastures, including animal welfare, biodiversity and low production costs are challenged by losses due to undetected disease, accidents and predation.

The transcription factor MebHLH18 in cassava functions in decreasing low temperature-induced leaf abscission to promote low-temperature tolerance

Frontiers in Plant Science, 2023
The reactive oxygen species (ROS) signal regulates stress-induced leaf abscission in cassava. The relationship between the function of the cassava transcription factor bHLH gene and low temperature-induced leaf abscission is still unclear.
