Radio Interference Prediction Method for EHV AC Transmission Lines at High Altitudes Based on Long‐Term Observations

High Voltage, EarlyView.
ABSTRACT Radio interference (RI) is a critical factor in the design of extra‐high voltage (EHV) transmission lines at high altitudes. To address the insufficient field data of RI on high‐altitude transmission lines, the lack of adequate validation for existing RI prediction methods, and the difficulty in assessing RI levels under various meteorological

Spatial magneto-seismology : effect of density stratification on the first harmonic amplitude profile of transversal coronal loop oscillations [PDF]

, 2007
Context. The new generation of extreme-ultraviolet (EUV) imagers onboard missions such as the Solar Dynamics Observatory (SDO)and Solar Orbiter (SO) will provide the most accurate spatial measurements of post-flare coronal loop oscillations yet.

How Are the Abnormally Hot Chromosphere and Corona Heated by the Solar Magnetic Fields?

The Astrophysical Journal
The corona is a structure possessed by stars, including the Sun. The abnormal heating of the solar corona and chromosphere is one of the greatest mysteries in modern astronomy.

The role and contribution of magnetic fields, characterized via their magnetic flux, to the statistical structuring of the solar atmosphere

Scientific Reports, 2022
The anomalous heating of the solar upper atmosphere is one of the eight key problems in modern astronomy. Moreover, the stratification of the solar atmosphere is an outstanding key-problem in solar physics.

Research on Self‐Identification Technology of Zero‐Value Insulators in Distribution Lines Based on Electroluminescence Effect

High Voltage, EarlyView.
ABSTRACT To address the issue of low detection accuracy for zero‐value insulators in distribution lines, this study proposes a novel method for detecting these insulators based on the electroluminescence effect. Through theoretical analysis and experimentation, it was found that the luminescence intensity of ZnS:Cu electroluminescent material varies ...

Solar cycle dependence of scaling in solar wind fluctuations [PDF]

, 2008
In this review we collate recent results for the statistical scaling properties of fluctuations in the solar wind with a view to synthesizing two descriptions: that of evolving MHD turbulence and that of a scaling signature of coronal origin that ...

Comparison of computed tomographic, radiographic and anatomical dorsal hoof wall measurements

Equine Veterinary Education, EarlyView.
Summary Background No comparison of radiographic and computed tomographic (CT) dorsal hoof wall (DHW) thickness and DHW to the palmar length of the distal phalanx (DHWDP) ratio has been published. Radiographic measurements obtained with and without radiodense markers on the DHW have not been compared.

POLAR investigation of the Sun—POLARIS [PDF]

, 2008
The POLAR Investigation of the Sun (POLARIS) mission uses a combination of a gravity assist and solar sail propulsion to place a spacecraft in a 0.48 AU circular orbit around the Sun with an inclination of 75° with respect to solar equator.

The Line Spectrum of the Solar Corona [PDF]

Publications of the Astronomical Society of the Pacific, 1945
For seventy years the solar corona has been observed at practically all eclipse expeditions. It consists of an approximately spherical halo, with faint streamers roughly radial in direction, extending a solar diameter or two from the photosphere, mainly from the spot zones. Curved rays also extend from the polar regions of the sun. The extent and shape

Understanding the Evidence Gaps: Diets and Fruit and Vegetable Intake Across Five Diverse Low‐ and Middle‐Income Countries

Maternal &Child Nutrition, EarlyView.
This perspective article synthesizes findings from scoping reviews examining diet and F&V intake, and interventions to increase F&V consumption among population groups in five countries: Benin, Fiji, the Philippines, Sri Lanka and Tanzania. ABSTRACT Poor dietary quality, particularly inadequate fruit and vegetable (F&V) intake, remains a significant ...
