Effective temperatures of hot Brownian motion [PDF]

open access: yesPhysical Review E, 2014
We derive generalized Langevin equations for the translational and rotational motion of a heated Brownian particle from the fluctuating hydrodynamics of its non-isothermal solvent. The temperature gradient around the particle couples to the hydrodynamic modes excited by the particle itself so that the resulting noise spectrum is governed by a frequency-

Temperature Relaxation in Hot Dense Hydrogen [PDF]

open access: yesPhysical Review Letters, 2008
Temperature equilibration of hydrogen is studied for conditions relevant to inertial confinement fusion. New molecular-dynamics simulations and results from quantum many-body theory are compared with Landau-Spitzer (LS) predictions for temperatures T from 50 eV to 5000 eV, and densities with Wigner-Seitz radii r_s = 1.0 and 0.5.

Efficacy of alternative cooling devices used for insulin storage without refrigeration under hot-humid environment

open access: yesAnnals of Medicine, 2022
Background Insulin is temperature sensitive as high temperatures reduce its potency. Refrigeration for insulin storage is still needed but households in remote areas do not have refrigerators.

Hot tearing behavior of NZ30K Mg alloy under progressive solidification [PDF]

open access: yesChina Foundry, 2021
Progressive solidification is usually considered an effective strategy to reduce the hot tearing susceptibility of a cast component. In this study, special constrained plate castings with progressive changes in cross-section were designed, which enabled ...

Managing Exertional Heat Stroke Among the Combatants [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2017
Exertional Heat Stroke (EHS) is a medical emergency which when not addressed timely can lead to high mortality and morbidity. Armed forces are vulnerable to heat stroke because of their involvement in strenuous physical exercises in extremes of climatic

Hot spot temperature prediction model of transformer based on GP-NLMS

open access: yes电力工程技术, 2022
An accurate estimation model of winding hot spot temperature is the key to assess the thermal state and insulation life of oil-immersed transformers. Based on the hot spot temperature and load current monitored by the substation,the genetic programming ...

Optimizing production efficiencies of hot water units using building energy simulations : trade-off between Legionella pneumophila contamination risk and energy efficiency [PDF]

open access: yes, 2019
The energy needed for domestic hot water represents an important share in the total energy use of well-insulated and airtight buildings. One of the main reasons for this high energy demand is that hot water is produced at temperatures above 60°C to ...

The effective temperatures of hot stars [PDF]

open access: yesSymposium - International Astronomical Union, 1997
We review the effective temperature scale of hot (≤ 10 kK) stars, including results from direct, continuum and ionization equilibrium techniques. We discuss the impact of recent developments in theoretical model atmospheres for OB subdwarfs, dwarfs and supergiants, white dwarfs and Wolf Rayet stars and present a revised Teff scale for OB stars.
