Temperature Distribution in Magnetized Neutron Star Crusts [PDF]

open access: yesAstronomy & Astrophysics, 2004
We investigate the influence of different magnetic field configurations on the temperature distribution in neutron star crusts. We consider axisymmetric dipolar fields which are either restricted to the stellar crust, ``crustal fields'', or allowed to penetrate the core, ``core fields''. By integrating the two-dimensional heat transport equation in the

A Method of Evaluating the Destruction of a Reinforced Concrete Hollow Core Slab for Ensuring Fire Resistance

open access: yesЖурнал інженерних наук, 2023
Fire tests of reinforced concrete floor slabs do not allow the detection of the onset of the boundary state due to loss of entirety because blocks are installed on the unheated surface to reproduce the design load.

A Distributed Temperature Sensing based soil temperature profiler

open access: yesGeoscientific Instrumentation, Methods and Data Systems, 2023
Abstract. Storage of heat in the soil is one of the main components of the energy balance, and is essential in studying the land-atmosphere heat exchange. However, its measurement proves to be difficult, due to (vertical) soil heterogeneity and sensors easily disturbing the soil.
