Optimizing washing conditions for smart fabrics: a comprehensive study.

This study aimed to determine optimal washing and drying methods for maintaining the functionality of silver-coated conductive knitted fabrics, commonly used in wearable smart products. By investigating changes in the physical, chemical, and electrical properties of these fabrics under various care conditions, we sought to provide recommendations for their proper maintenance. Results showed that mechanical friction during washing, combined with the chemical effect of detergent and the effects of machine drying, led to peeling and oxidation of the silver layer, resulting in changes to the fabric's appearance, color and increased surface resistance.

Effects of the Change in Respiratory Kinematics on the Singing Voice: Re-Visiting the Benefits of Diaphragmatic-Abdominal Breathing in Professional Singers with Problems in Pitch.

To assess the effect of voice therapy on pitch in professional singers with faulty respiratory kinematics. In this prospective interventional study, professional singers with easy voice fatigability and inability to reach higher pitches, following appropriate selection criteria, were subjected to a 1-month structured voice therapy that transformed their predominant breathing pattern from thoracic to diaphragmatic-abdominal. Acoustic parameters (pitch range and its extreme values before/after therapy, and difference in pitch range) were analyzed using Praat software and compared using standard statistical methods (paired -test).

Improved energy equations and thermal functions for diatomic molecules: a generalized fractional derivative approach.

Context: This work presents analytical expressions for ro-vibrational energy models of diatomic molecules by introducing fractional parameters to improve molecular interaction analysis. Thermodynamic models, including Helmholtz free energy, mean thermal energy, entropy, and isochoric heat capacity, are formulated for diatomic molecules such as CO (X ∑), Cs (3 ∑), K (X ∑), Li (6 Π), Li (1 Δ), Na (5 Δ), Na (C(2) Π), and NaK (c ∑). The incorporation of fractional parameters improves predictive accuracy for vibrational energies, as shown by reductions in percentage average absolute deviations from 0.
