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.

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).

  • The WHO declared COVID-19 a public health emergency in January 2020 and a pandemic in March 2020, prompting NIMHANS to launch a national helpline to address mental health issues during this crisis.
  • An analysis of 70 helpline callers revealed that 71.1% were aged 60-70, 38.6% had preexisting mental illnesses (mainly anxiety and sleeplessness), and many faced additional medical issues.
  • The study found that telephonic interventions, including supportive psychotherapy and information about COVID-19, were effective in addressing the mental health concerns of the elderly during the pandemic.

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

J Mol Model

November 2024

Department of Science Laboratory Technology, School of Science and Technology, The Federal Polytechnic, P.M.B. 1006, Damaturu, Yobe State, Nigeria.

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.

  • - The study aimed to compare the effects of isometric handgrip exercise (IHG) and aerobic exercise (AE) on blood pressure reduction in older hypertensive adults over a 12-week period.
  • - Participants were divided into three groups: IHG, AE, and a no-exercise control group, with both IHG and AE showing significant reductions in systolic blood pressure compared to the control.
  • - IHG was particularly effective in lowering diastolic blood pressure, suggesting it could be a beneficial alternative treatment for managing hypertension in individuals aged 60 and older.
