Thermal properties of cement mortar with different mix proportions

open access: yesMateriales de Construccion, 2020
The energy required for the heating and cooling of buildings is strongly dependant on the thermal properties of the construction material. Cement mortar is a common construction material that is widely used in buildings.

The effect of urban heat island on groundwater located in shallow aquifers of Kütahya city center and shallow geothermal energy potential of the region, Turkey

open access: yesBulletin of the Mineral Research and Exploration, 2021
As a result of urbanization, natural surfaces are replaced by artificial surfaces that trap heatsuch as buildings, pavements and asphalt, so residential areas have higher temperature values than rural areas. This effect, defined as the urban heat island,

Heat Capacity of PbS: Isotope Effects [PDF]

open access: yes, 2007
In recent years, the availability of highly pure stable isotopes has made possible the investigation of the dependence of the physical properties of crystals, in particular semiconductors, on their isotopic composition. Following the investigation of the

Markovian heat sources with the smallest heat capacity

open access: yesNew Journal of Physics, 2018
Thermal Markovian dynamics is typically obtained by coupling a system to a sufficiently hot bath with a large heat capacity. Here we present a scheme for inducing Markovian dynamics using an arbitrarily small and cold heat bath.

Heat capacity of liquids: A hydrodynamic approach [PDF]

open access: yes, 2015
We study autocorrelation functions of energy, heat and entropy densities obtained by molecular dynamics simulations of supercritical Ar and compare them with the predictions of the hydrodynamic theory.

Some operative applications of remote sensing

open access: yesAnnals of Geophysics, 2000
Among the methods of applied geophysics, remote sensing plays a major and an ancillary role, at the same time. The major role deals with the acquisition and processing of data with the aim of describing the properties of the surfaces and their subsurface

Vibrational entropy and microstructural effects on the thermodynamics of partially disordered and ordered Ni3V [PDF]

open access: yes, 1997
Samples of Ni3V were prepared with two microstructures: (1) with equilibrium D022 order, and (2) with partial disorder (having a large D022 chemical order parameter, but without the tetragonality of the unit cell).
