Eliminating Infrared Divergences in the Pressure [PDF]

open access: yes, 1996
The pressure of a system in thermal equilibrium is expressed as a mass integral over a sum of thermal propagators. This allows a Dyson resummation and is used to demonstrate that potential infrared divergences are rendered harmless.Comment: 6 pages plain

A Review of Thermally Activated Building Systems (TABS) as an Alternative for Improving the Indoor Environment of Buildings

open access: yesEnergies, 2022
Among the alternatives for improving the thermal comfort conditions inside buildings are the thermally activated building systems (TABS). They are embedded in different building components to improve the indoor air temperature. In this work, a review and

Thermal mass shift of nucleons [PDF]

open access: yesPhysics Letters B, 1997
Abstract The mass shift ΔmN of a nucleon in the finite temperature pion gas is calculated in the case of an arbitrary nucleon momentum. A general formula is used which relates the in-medium mass shift Δm(E) of a particle to the real part of the forward scattering amplitude Re F(E) of this particle on the constituents of the medium and its ...

WIMPless Dark Matter from an AMSB Hidden Sector with No New Mass Parameters

open access: yes, 2011
We present a model with dark matter in an anomaly-mediated supersymmetry breaking hidden sector with a U(1)xU(1) gauge symmetry. The symmetries of the model stabilize the dark matter and forbid the introduction of new mass parameters.

The Impacts of a Building’s Thermal Mass on the Cooling Load of a Radiant System under Various Typical Climates

open access: yesEnergies, 2020
Cooling load is difficult to predict for a radiant system, because the interaction between a building’s thermal mass and radiation heat gain has not been well defined in a zone with a cooling surface. This study aims to reveal the effect of thermal

Thermal and Fragmentation Properties of Star-forming Clouds in Low-metallicity Environments

open access: yes, 2005
The thermal and chemical evolution of star-forming clouds is studied for different gas metallicities, Z, using the model of Omukai (2000), updated to include deuterium chemistry and the effects of cosmic microwave background (CMB) radiation.

Unexpectedly large mass loss during the thermal pulse cycle of the red giant R Sculptoris! [PDF]

open access: yes, 2012
The asymptotic giant branch star R Sculptoris is surrounded by a detached shell of dust and gas. The shell originates from a thermal pulse during which the star undergoes a brief period of increased mass loss. It has hitherto been impossible to constrain

Experimental Evidence of the Coupling between the Energy Charge–Discharge and Natural Ventilation in a Full-Scale Passive Building

open access: yesBuildings, 2023
An experimental study was carried out on a full-scale passive building equipped with global and local instrumentation with the aim of characterizing the energy charge and discharge processes and their coupling to the outdoor thermal stresses, especially ...

Reuse Waste Material and Carbon Dioxide Emissions to Save Energy and Approach Sustainable Lightweight Portable Shelters

open access: yesEnvironmental and Climate Technologies, 2020
Despite their great significance, lightweight structures have poor thermal inertia. In order to enhance the thermal comfort inside such buildings, architects need lightweight thermal storage.

Visualization of Local Concentration and Viscosity Distribution during Glycerol-Water Mixing in a Y-Shape Minichannel: A Proof-of-Concept-Study

open access: yesMicromachines, 2021
The work presents an efficient and non-invasive method to visualize the local concentration and viscosity distribution of two miscible and non-reacting substances with a significant viscosity difference in a microchannel with a Y-shape cell. The proof-of-
