Heat Treatment’s Effect on Properties of Polystyrene from Building Demolitions
BioResources, 2023 Polystyrene (PS) is a synthetic polymer widely used as a packaging material and in thermal insulation of buildings. At end-of-life, there are not many recycling management options of PS because of the reduced incentive and high cost.

Measurement of sound speed versus depth in Antarctic ice with the South Pole Acoustic Test Setup [PDF]
, 2008 The feasibility and design of an acoustic neutrino detection array in the South Pole ice depend on the acoustic properties of the ice. The South Pole Acoustic Test Setup (SPATS) was built to evaluate the acoustic characteristics of the ice in the 1 to ...

The acoustic properties of snores [PDF]
European Respiratory Journal, 1995 This study was undertaken in an attempt to characterize the acoustic properties of snoring sounds in the time and frequency domains, and to correlate between these properties and the mechanical events underlying their production. Three experimental set-ups were used: 1) Dog model--six mongrel dogs, in which partial upper airway obstruction was created ...

Similarities between action potentials and acoustic pulses in a van der Waals fluid [PDF]
, 2018 An action potential is typically described as a purely electrical change that propagates along the membrane of excitable cells. However, recent experiments have demonstrated that non-linear acoustic pulses that propagate along lipid interfaces and ...

Seismic signatures of magnetic activity in solar-type stars observed by Kepler [PDF]
, 2018 The properties of the acoustic modes are sensitive to magnetic activity. The unprecedented long-term Kepler photometry, thus, allows stellar magnetic cycles to be studied through asteroseismology.
