Closed-form equations that describe the vector irradiance from an isotropic source embedded in the oceanare rigorously derived from the steady-state radiative transfer equation. The equations are exact for a homogeneous medium and are believed to be an excellent approximation along the vertical axis for a plane-parallel ocean. The equations are solved for the absorption coefficient as a functio...

Introduction: Exposure to noise pollution in the workplace is one of the most common occupational hazards and causes hearing loss. One of the ways to control voice in the control industry is by audio absorbers. Nanoparticles can be used to composite materials. The purpose of this study was to design and construct acoustic panels based on gypsum, silicon oxide nanoparticles, hydrolyzed cotton an...
