A Rewriting-Logic-Based Technique for Modeling Thermal Systems

open access: yes, 2010
This paper presents a rewriting-logic-based modeling and analysis technique for physical systems, with focus on thermal systems. The contributions of this paper can be summarized as follows: (i) providing a framework for modeling and executing physical ...

The age and origin of the central Scotia Sea [PDF]

open access: yes, 2010
Opening of the Drake Passage gateway between the Pacific and Atlantic oceans has been linked in various ways to Cenozoic climate changes. From the oceanic floor of Drake Passage, the largest of the remaining uncertainties in understanding this opening is

Reconciling Seismic and Thermo‐Chemical Models of Cratonic Lithosphere

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 2, February 2026.
Abstract Most published global and regional shear‐wave (VS ${V}_{\mathrm{S}}$) velocity models of cratons include a VS ${V}_{\mathrm{S}}$ increase with depth below the Moho, with a maximum at 100–150 km depth. This feature has long been debated, as it appears to require either (implausible) temperature decreases with depth, or substantial, layered ...

Evaluating different geothermal heat-flow maps as basal boundary conditions during spin-up of the Greenland ice sheet [PDF]

open access: yesThe Cryosphere
There is currently poor scientific agreement on whether the ice–bed interface is frozen or thawed beneath approximately one third of the Greenland ice sheet.

Oceanic topography and heatflow: Indications for a silent discharge of cold rock into the convecting Earth

open access: yesGeophysical Research Letters, 1995
The 2.5 km mean relative elevation of mid ocean ridges is arguably consistent with a steady state thickness of ≈100 km for the oceanic lithosphere. Here we explore some consequences of this particular value. Based on seismic models of the uppermost oceanic mantle, we infer that no significant heat is added to normal asthenosphere following accretion at

Deep Temperature and Heat-Flow Characteristics in Uplifted and Depressed Geothermal Areas

open access: yesEnergies
To address the high costs and inefficiencies of blind prospecting in deep geothermal exploration, this study develops a three-dimensional heat transfer model for quantitative prediction of geothermal enrichment targets.

Perturbative and Numerical Analysis of Tilted Cosmological Models of Bianchi type V

open access: yes, 2005
Cosmological models of Bianchi type V and I containing a perfect fluid with a linear equation of state plus cosmological constant are investigated using a tetrad approach where our variables are the Riemann tensor, the Ricci rotation coefficients and a ...

Impregnation and saturation analysis of microwave‐preheated reactive resin in liquid composite molding

open access: yesPolymer Composites, Volume 46, Issue S1, Page S159-S170, 10 September 2025.
Analysis of the improvements of impregnating and saturating resin flows in microwave‐preheated liquid composite molding. Abstract In liquid composite molding processes, resin preheating is a strategy to reduce the viscosity, which consequently improves resin flow and reduces impregnation time. However, the provision of heat to thermoset systems must be

Isothermal micro calorimetry – a new method for MIC determinations: results for 12 antibiotics and reference strains of E. coli and S. aureus

open access: yesBMC Microbiology, 2009
Background Antimicrobial susceptibility testing of microorganisms is performed by either disc diffusion or broth dilution tests. In clinical use, the tests are often still performed manually although automated systems exist.

Temperature and pressure corrections applied to rock thermal conductivity: impact on subsurface temperature prognosis and heat-flow determination in geothermal exploration

open access: yesGeothermal Energy, 2020
Precise knowledge of the subsurface thermal field plays a key role in the assessment of geothermal targets. Unfortunately, deep underground temperature data is generally scarce and a matter of research.
