, 2021 AbstractAcoustic emission (AE) is one of the most promising methods for structural health monitoring (SHM) of materials and structures. Because of its passive and non-invasive nature, it can be used during the operation of a structure and supply information that cannot be collected in real time through other techniques. It is based on the recording and

Emissivity measurements of reflective surfaces at near-millimeter wavelengths [PDF]
, 1995 We have developed an instrument for directly measuring the emissivity of reflective surfaces at near-millimeter wavelengths. The thermal emission of a test sample is compared with that of a reference surface, allowing the emissivity of the sample to be ...

Neutrino Emissivity of Dense Stars [PDF]
, 1995 The neutrino emissivity of compact stars is investigated in this work. We consider stars consisting of nuclear as well as quark matter for this purpose.

Low frequency measurements of synchrotron absorbing HII regions and modeling of observed synchrotron emissivity [PDF]
, 2018 Cosmic rays (CRs) and magnetic fields are dynamically important components in the Galaxy, and their energy densities are comparable to that of the turbulent interstellar gas.

, 2022 Environmental regulations and their enforcement play a critical role in reducing emissions and their devastating effects on humanity and the environment. However, many developing countries have large informal sectors—accounting for more than 70 percent of total employment, that operate outside

EMBO reports, 2011 Howy argues that sophisticated communication technology is no substitute for the face‐to‐face contacts that are vital to scientific work. Instead of ever‐fancier electronic devices, we should be focusing on making travel more efficient and humane.

Observational Characterization of the Downward Atmospheric Longwave Radiation at the Surface in the City of São Paulo [PDF]
, 2010 This work describes the seasonal and diurnal variations of downward longwave atmospheric irradiance (LW) at the surface in São Paulo, Brazil, using 5-min-averaged values of LW, air temperature, relative humidity, and solar radiation observed continuously

Hemispherical total emissivity and specific heat capacity of deeply undercooled Zr41.2Ti13.8Cu12.5Ni10.0Be22.5 melts [PDF]
, 1995 High-temperature high-vacuum electrostatic levitation (HTHVESL) and differential scanning calorimetry (DSC) were combined to determine the hemispherical total emissivity epsilon T, and the specific heat capacity cp, of the undercooled liquid and ...

Phase transition of color-superconductivity and cooling behavior of quark stars [PDF]
, 2001 We discuss the color-superconductivity and its effect on the cooling behavior of strange quark stars. The neutrino emissivity and specific heat of quark matter are calculated within the BCS theory.
