Sound absorption mechanism of underwater anechoic coating with spherical cavities

Journal of Mechanics
Abstract An axisymmetric theoretical model is simplified to investigate sound absorption in the underwater anechoic coating with spherical cavities. An empirical equation is put forward to predict the frequency at the first absorption peak.

Industrial Hydrocarbons Exposure Deteriorates Sperm Integrity and Reproductive Function

Journal of Biochemical and Molecular Toxicology, Volume 40, Issue 8, August 2026.
ABSTRACT Occupational exposure to polycyclic aromatic hydrocarbons (PAHs) or metal fumes in the workplace may be detrimental to male fertility. The present study compared sperm concentration, total motility, strict morphology and oxidative stress and SDF levels between 81 men, controls (n = 17) and workers from plastic industry workers (n = 18), steel ...

An investigation of the sound of foam and its potential influence on the shampoo experience

International Journal of Cosmetic Science, Volume 48, Issue 4, Page 725-737, August 2026.
This study investigates shampoo foam acoustics' impact on hair washing experience using binaural recordings and psychoacoustic analysis. Distinct foam sound profiles elicited varying emotional responses; early lathering induced negative emotions while later phases were positive.

Cybersecurity in aquaculture: Risks, governance, and future directions across production systems

Journal of the World Aquaculture Society, Volume 57, Issue 4, August 2026.
Abstract Aquaculture is becoming increasingly dependent on connected sensors, remote monitoring, edge and cloud analytics, automation, and digital traceability; however, the cybersecurity evidence base remains fragmented and low‐trophic systems are markedly underrepresented.
