Development and thermal requirements of the Nearctic predator Geocoris punctipes (Hemiptera: Geocoridae) reared at constant and alternating temperatures and fed on Anagasta kuehniella (Lepidoptera: Pyralidae) eggs

open access: yesEuropean Journal of Entomology, 2014
Knowledge of the optimal temperatures for development and survival of biological control agents is essential for efficient mass-rearing and introduction of natural enemies in augmentative biological control programs. We studied the effect of constant and

Research on wellhead flow detection method at low Reynolds number

open access: yesInternational Journal of Thermofluids, 2023
The detection of wellhead fluid flow is critical in the development of low-production wells. The production status can be evaluated according to the flow of production wells. The thermal flowmeter designed in this paper mainly measures the flow of single-

Thermal decay of the cosmological constant into black holes [PDF]

open access: yesPhysical Review D, 2004
We show that the cosmological constant may be reduced by thermal production of membranes by the cosmological horizon, analogous to a particle ``going over the top of the potential barrier", rather than tunneling through it. The membranes are endowed with charge associated with the gauge invariance of an antisymmetric gauge potential.

Study of thermodynamics of a thermal electron in scattering

open access: yesHeliyon, 2022
This work presents the study of the thermodynamic properties of thermal electrons participating in scattering events. This is necessary because scattering with a thermal electron in presence of a laser field was not studied yet and it reduces the ...

$$a_{1}$$ a 1 meson-nucleon coupling constant at finite temperature from the soft-wall AdS/QCD model

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
We study the temperature dependence of the $$a_1$$ a 1 meson-nucleon coupling constant in the framework of the soft-wall AdS/QCD model with thermal dilaton field.

Thermal Time Constant - TTC

open access: yes, 2022
The design of a building's exterior walls has an important influence on energy consumption, building cost and thermal comfort. It influences also heating and cooling devices’ size. Optimization of energy consumption of the building requires consideration of the building materials, their thickness and mass, type and thickness of insulation, and location

Comparison of Turbulent Thermal Convection between Conditions of Constant Temperature and Constant Flux [PDF]

open access: yesPhysical Review Letters, 2009
We report the results of high resolution direct numerical simulations of two-dimensional Rayleigh-Bénard convection for Rayleigh numbers up to $\Ra=10^{10}$ in order to study the influence of temperature boundary conditions on turbulent heat transport. Specifically, we considered the extreme cases of fixed heat flux (where the top and bottom boundaries
