Change in Vocal Resonance Following Sinonasal Surgery

open access: yesWorld Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Objectives Delineate objective and clinician‐perceived subjective changes in voice quality following sinonasal surgery. Methods Prospective cohort study of six adults who completed pre‐ and post‐operative voice recordings which were analyzed for jitter, shimmer, noise to harmonic ratio (NHR), cepstral peak prominence (CPP), formant and anti ...

Evaluation Methodology, Numerical Verification and Retrofilling Procedure for Power Transformers to Ensure K‐Class Flame Retardancy and Environmentally Friendly

open access: yesHigh Voltage, EarlyView.
ABSTRACT With increasing demands for fire safety and environmental friendliness, retrofilling transformers with alternative insulating liquids has become a growing trend. However, retrofilling power transformers remains uncertain, as more residual mineral oil compromises K‐class flame retardancy, and its impact on environmental performance has yet to ...

Current‐Carrying Characteristics of High‐Voltage Land Cables With Different Grounding Methods for Low‐Frequency AC Transmission

open access: yesHigh Voltage, EarlyView.
ABSTRACT Low‐frequency AC transmission holds promise for high‐voltage land cables, but its ampacity is significantly influenced by cable grounding methods and other structural factors. To explore the specific low‐frequency current‐carrying characteristics of high‐voltage land cables, this paper conducts a thorough theoretical analysis of the coupling ...

Decoding KGK VI Population Movements: Strontium Isotope and Proteomic Insights from the Gumelnița Site (Romania)

open access: yes
Abstract The Kodjadermen-Gumelnița-Karonovo VI human group (KGK VI) reached its maximal extension around 4500 BC, covering a large area comprised between southern Ukraine and northern Greece. Afterward, its distribution gradually receded, before vanishing altogether at the end of the fifth – early fourth millenniums BC.

An Improved Method for Calculating the Radiative Cooling Heat Dissipation Power of an Oil‐Natural‐Air‐Natural Transformer

open access: yesHigh Voltage, EarlyView.
ABSTRACT Radiative cooling holds potential for outdoor transformers in operation due to its zero‐energy consumption and high adaptability and has demonstrated effective heat dissipation in simulations of small distribution transformers. Accurate calculation of the transformer temperature rise and the radiative cooling effect is crucial for practical ...
