Efficacy of Semen Microencapsulation Technique on the Quality of Spermatozoa From Canindé Goats Kept Under Refrigeration for Three Days. [PDF]
Reprod Domest AnimABSTRACT 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 ...

On the amplitude of the Chandler wobble [PDF]
Geophysical Journal International, 1977 The change in the inertia tensor of the Earth, due to the mass shift following a seismic event, has been computed by several authors for non-rotating earth models. Rotation is taken into account in the present paper, and the additional change in the inertia tensor is computed for an equivalent earth model, in which the axis of geometrical symmetry ...

Geophysical Research Letters, Volume 50, Issue 12, 28 June 2023., 2023 Abstract Climate model estimates show significant groundwater depletion during the 20th century, consistent with global mean sea level (GMSL) budget analysis. However, prior to the Argo float era, in the early 2000’s, there is little information about steric sea level contributions to GMSL, making the role of groundwater depletion in this period less ...

Anthropause environmentalisms: Noticing natures with the Self‐Isolating Bird Club
Transactions of the Institute of British Geographers, Volume 48, Issue 2, Page 232-248, June 2023., 2023 Short Abstract This paper offers a detailed empirical account of how human‐environment relations were reconfigured in the UK and Ireland during the 2020–2021 COVID‐19 lockdowns, a period which natural scientists defined as the COVID‐19 Anthropause. Bringing this scientific concept into conversation with geographical work, we consider anthropause as ...

The numerical prediction of the Earth’s polar motion based on an advanced multivariate algorithm
Frontiers in Astronomy and Space Sciences, 2023 Since there are complicated changes in the polar motion (PM) from sub-annual to decadal, precisely predicting it is challenging. Here, we provide an advanced multivariate algorithm by combining an iterative oblique singular spectrum analysis (IOSSA) with

On Two Formulations of Polar Motion and Identification of Its Sources
Geosciences, 2022 Differences in formulation of the equations of celestial mechanics may result in differences in interpretation. This paper focuses on the Liouville-Euler system of differential equations as first discussed by Laplace.

Excitation of the Earth's Chandler wobble by a turbulent oceanic double-gyre [PDF]
, 2017 We develop a layer-averaged, multiple-scale spectral ocean model and show how an oceanic double-gyre can communicate with the Earth's Chandler wobble. The overall transfers of energy and angular momentum from the double-gyre to the Chandler wobble are ...

A possible interrelation between Earth rotation and climatic variability at decadal time-scale
Geodesy and Geodynamics, 2016 Using multichannel singular spectrum analysis (MSSA) we decomposed climatic time series into principal components, and compared them with Earth rotation parameters. The global warming trends were initially subtracted.

On a possible connection between Chandler wobble and dark matter [PDF]
, 2009 Chandler wobble excitation and damping, one of the open problems in geophysics, is treated as a consequence in part of the interaction between Earth and a hypothetical oblate ellipsoid made of dark matter.

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.
