Determination of Global Stability of the Slosh Motion in a Spacecraft via Num Erical Experiment [PDF]
Journal of Astronomy and Space Sciences, 2003 The global stability of the attitude motion of a spin-stabilized space vehicle is investigated by performing numerical experiment. In the previous study, a stationary solution and a particular resonant condition for a given model were found by using ...

Sensors, 2021 Very long baseline interferometry (VLBI) is the only technique in space geodesy that can determine directly the celestial pole offsets (CPO). In this paper, we make use of the CPO derived from global VLBI solutions to estimate empirical corrections to ...

Red Light and Glucose Enhance Cytokinin-Mediated Bud Initial Formation in Physcomitrium patens
Plants, 2022 Growth and development of Physcomitrium patens is endogenously regulated by phytohormones such as auxin and cytokinin. Auxin induces the transition of chloronema to caulonema.

About the Free and Forced Nutation: The Daily Nutation [PDF]
American Journal of Astronomy and Astrophysics, 2021 To explain the nutation phenomenon, Euler chose a geocentric frame of coordinates to present his dynamical equations. In accordance with his formulas, the nutation is caused by a momentum relative to the Earth's center, due to certain external forces. Further, Poinsot presented a special case of the Euler's equations, when any momentum of those certain

Mars nutation resonance due to Free Inner Core Nutation [PDF]
Journal of Geophysical Research: Planets, 2003 The rotational normal modes of the planet Mars are computed using a numerical approach. We deduce the associated resonances in the nutations induced by the external gravitational forcing from the Sun, Phobos, and Deimos. In particular, the influence of a possible solid inner core inside a liquid core is investigated.

Long-period nutational-precessional motions of the instantaneous Earth rotation pole
Учёные записки Казанского университета: Серия Физико-математические науки, 2020 The influence of the rotational regime on real long-period nutational-precessional motions of the instantaneous pole of the Earth’s rotation is considered. The solar magnetospheric (through changes in the angular velocity of rotation) mechanism of action

Basic Earth's Parameters as estimated from VLBI observations
Geodesy and Geodynamics, 2017 The global Very Long Baseline Interferometry observation for measuring the Earth rotation's parameters was launched around 1970s. Since then the precision of the measurements is continuously improving by taking into account various instrumental and ...

Free core nutation: new large disturbance and connection evidence with geomagnetic jerks [PDF]
, 2015 Variations in free core nutation (FCN) are connected with various processes in the Earth's fluid core and core-mantle coupling, which are also largely responsible for the geomagnetic field variations, particularly the geomagnetic jerks (GMJs). A previous
