A Test Method for Acoustic Emission Properties of Natural Cellulose Fiber-Reinforced Composites
Applied Sciences, 2021 To test the acoustic performance of fiber-reinforced composites for replacing wood, an acoustic vibration test method is developed. For evaluation of the test method, composites are manufactured using hemp and ramie embedded in epoxy, through vacuum ...

Investigations on the Performance of Various Horizontal Ground Electrodes
Energies, 2021 Experimental work on grounding systems has shown that the characteristics of grounding systems under high impulse conditions are different than those obtained at steady-state conditions.

Pulmonary Functions and Inflammatory Biomarkers in Post-Pulmonary Tuberculosis Sequelae [PDF]
Tuberculosis and Respiratory Diseases, 2022 Background Post-tuberculosis (TB) sequelae is a commonly encountered clinical entity, especially in high TB burden countries. This may represent chronic anatomic sequelae of previously treated TB, with frequent symptomatic presentation.

Energies, 2021 Ionisation can occur in the soil when high impulse currents are subjected to grounding systems. This occurrence is generated by a difference in the dielectric strength value between the soil and air voids.

Evaluation of Respiratory Impedance in Asthma and COPD by an Impulse Oscillation System
Internal Medicine, 2010 The purpose of this study was to clarify the differences in physiological properties of the airways between asthma and COPD using an impulse oscillation system (IOS).Subjects comprised 95 stable COPD patients, 52 never-smoker asthma patients and 29 healthy never-smokers >60 years old, all matched for age, in whom respiratory impedance was examined by ...

Impedance and impulse response measurements using low-cost components [PDF]
The Journal of the Acoustical Society of America, 1982 A thin 27-mm-o.d. disk transducer (from Radio Shack 273-060 signaler) is RTV sealed to the end of a measurement tube whose 15 mm i.d. not only approximates the transducer disk's nodal circle but also the i.d. of a clarinet, sax, or trumpet mouthpiece. A 10-mm-o.d.

A Study on Frequency Response Functions in Pavement Engineering
The Baltic Journal of Road and Bridge Engineering, 2023 Mechanical impedance (MI) defines the ability of a system to vibrate as a consequence of force application. In the recent years, the correlation of this parameter with tire-road noise and other characteristics has gained certain attention.

Measurement of impulse noise propagation over natural impedance surfaces [PDF]
The Journal of the Acoustical Society of America, 1985 The peak sound pressure level decay with distance of the impulse noise from hand grenade simulators has been measured over the following types of surfaces: water, swamp, rocky ground with small bushes, dead grass with sparse snow cover, and dense evergreen forest. The ground impedance is estimated for each surface using the calculation of R. Raspet. H.

Reciprocal control of viral infection and phosphoinositide dynamics
FEBS Letters, EarlyView.Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

FEBS Letters, EarlyView.We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...
