SYNCHRONIZATION OF TERRESTRIAL PROCESSES WITH FREQUENCIES OF THE EARTH-MOON-SUN SYSTEM

Odessa Astronomical Publications, 2016
It is established that the frequencies of the quasi-biennial oscillation (QBO) of atmospheric winds and the Chandler wobble (CW) of the Earth's poles are synchronized with each other and with the fundamental frequencies of the Earth–Moon–Sun system.

The Rheology of the Earth in the Intermediate Time Range

Annals of Geophysics, 1970
The evidence bearing upon the rheology of the " tectonically<br />significant layers" of the Earth (" tectonosphere ") in the intermediate<br />time range (4 hours to 15000 years) is analyzed.

Research on Polar Motion Prediction Accuracy Based on ETH and GFZ Angular Momentum Forecast Products

Earth and Space Science, Volume 13, Issue 5, May 2026.
Abstract Polar motion (PM), a critical element of Earth Orientation Parameters (EOP), is essential for high‐precision applications such as deep space exploration and satellite navigation. Recent advances in prediction methods utilizing Effective Angular Momentum (EAM) data have become a key pathway for enhancing PM forecast accuracy.

Self‐Consistent Models of Earth's Mantle and Core From Long‐Period Seismic and Tidal Constraints

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract Here we illustrate the use of parameterized models to address fundamental questions about Earth's mantle and core structure. For this, we invert a large set of normal‐mode center frequencies and quality (attenuation) factors, along with astronomic‐geodetic data, for the radial anelastic seismic structure of the Earth.

Numerical solutions of rotational normal modes of a triaxial two-layered anelastic Earth

Geodesy and Geodynamics, 2019
The Earth's rotational normal modes depend on Earth model used, including the layer structures, principal inertia moments of different layers and the compliances.

Efficacy of Semen Microencapsulation Technique on the Quality of Spermatozoa From Canindé Goats Kept Under Refrigeration for Three Days

Reproduction in Domestic Animals, Volume 60, Issue 11, November 2025.
ABSTRACT For approximately 40 years, microencapsulation technology has been utilised across various species due to its ability to release semen gradually after artificial insemination. This study aimed to establish the use of the alginate microencapsulation procedure for goat semen and to investigate whether this method enhances longevity during cold ...

ENSO Modulates the Oceanic Excitation of Polar Motion

Geophysical Research Letters, Volume 52, Issue 18, 28 September 2025.
Abstract The El Niño–Southern Oscillation (ENSO) exerts a strong control on interannual length‐of‐day variations, but its imprint on polar motion excitation remains to be identified. We explore the hypothesis that part of this imprint is embedded in oceanic angular momentum (OAM) changes, particularly that component driven by ocean bottom pressure pb $\
