High Voltage, EarlyView.ABSTRACT Currently, limited research exists on the structural response and protection methods of the converter transformer tank for ± 800 kV ultra‐high voltage direct current transmission project to high energy arc faults. This research investigates the dynamic response and the vulnerable areas of the ultra‐high voltage converter transformer under the ...

The effects of strong shock waves on mortality rates and percentages of pulmonary lesions in rats as a function of the number of exposures [PDF]
The results of the study reveal that with regard to the pulmonary lesions, twice the number of exposures is compensated for by quartering the overpressure of the wave crest.

Updating the aerodynamic resistance for subsurface ventilation [PDF]
, 2019 For the safety works in the mines good ventilation is one of the main requirements. For miners’ performance, the subsurface ventilation creates healthier and more hygienic conditions. Mine ventilation has always belonged to the field of mining. Moreover,

Influence of Arc Faults on Pressure Production Characteristics in AC Turret of UHV Transformers
High Voltage, EarlyView.ABSTRACT The overpressure caused by arc fault in the oil tank can lead to a transformer explosion. Since the AC turret of transformers serves to connect the transformer windings with the AC busbar, the arc current can be extremely high if an earth fault arc occurs leading to potentially hazardous pressure.

Magmatic intrusions control Io's crustal thickness
, 2020 Io, the most volcanically active body in the solar system, loses heat through eruptions of hot lava. Heat is supplied by tidal heating and is thought to be transferred through the mantle by magmatic segregation, a mode of transport that sets it apart ...

Drift velocity and pressure monitoring of the CMS muon drift chambers
, 2010 The drift velocity in drift tubes of the CMS muon chambers is a key parameter for the muon track reconstruction and trigger. It needs to be monitored precisely in order to detect any deviation from its nominal value.

EFFECTS OF OVERPRESSURE ON THE EAR‐A REVIEW*
Annals of the New York Academy of Sciences, 1968 Abstract : Information regarding blast effects on the ear is reviewed in an attempt to gather quantitative information available for animals and man for help in the establishment of relationships between various levels of overpressure and the incidence of eardrum failure, the degree of damage to the middle and inner ear and other identifiable sequelae ...

Rapid Communications in Mass Spectrometry, Volume 40, Issue 14, 30 July 2026.ABSTRACT Rationale Pollution of surface and shallow groundwater by nitrate (NO3−$$ {\mathrm{NO}}_3^{-} $$) is a global concern, resulting in the deterioration of drinking water quality. Stable isotopes of NO3−$$ {\mathrm{NO}}_3^{-} $$ (δ15N and δ18O) can be used to trace its sources and identify prevailing biogeochemical processes.
