Abstract:

In the literature, Holditch theorem was obtained under periodic rotation and translation motions in [H. Holditch, Geometrical theorem, Q. J. Pure Appl. Math. 2 (1858) 38] or periodic shear and translation motions in [O. Röschel, Der satz von Holditch in der isotropen ebene. Abh. Braunschweig. Wiss. Ges. 36 (1984) 27–32]. In this paper, by introducing the projection of a vector onto a plane, scalar area, area vector of a surface, we investigate Holditch theorem under periodic rotation, translation and shear motions. We give two interpretations for the Holditch type theorem in Galilean space.

This study investigates the theoretical basis of the quasi-frame in three-dimensional Galilean geometry. We derive mathematical expressions for the position vectors of curves defined in relation to this quasi-frame and establish the quasi equations that govern their behavior. Our findings demonstrate the absence of normal curves in Galilean 3-space, challenging existingtheories in the field and providing new insights into the geometric structure of the Galilean 3-space. We explore the geometric properties of quasi-rectifying and quasi-osculating curves, establishing the necessary and sufficien

Context. Bright stellar positions are now known with an uncertainty below 1 mas thanks to Gaia DR2. Between 2019–2020, the Galactic plane will be the background of Jupiter. The dense stellar background will lead to an increase in the number of occultations, while the Gaia DR2 catalogue will reduce the prediction uncertainties for the shadow path. Aims. We observed a stellar occultation by the Galilean moon Europa (J2) and propose a campaign for observing stellar occultations for all Galilean moons. Methods. During a predicted period of time, we measured the light flux of the occulted star and

In-plane stress distribution in a spinning annular disk is studied analytically. The disk is clamped at the inner boundary and subjected to a stationary distributed load along the outer boundary. The solution is determined through a Galilean transformation by using the Lame´ potential functions and the two-dimensional elasticity theory. Numerical results are presented for WA vitrified grinding wheels with outer radii of 50 mm and inner radii of 25 mm rotating at 3000 rpm and 15000 rpm.

In particular, we obtain the explicit parameter equations of the T-slant helices and prove that there are no N-slant and B-slant helices in G13. We also prove that there are no Darboux helices in the same space.

Using these new sets of constants, significant improvement is noticed in the O-C values of the sky plane coordinates of the mutual event data set and residuals in longitude for Io and Europa are found to improve.

The study of the geometry of surfaces having a codimension greater than one in multidimensional spaces is one of the most difficult problems in geometry. When the multidimensional geometry under consideration has a pseudo-Euclidean metric, its complexity increases. Two-dimensional surfaces in a five-dimensional pseudo-Euclidean space of index two are considered in the article. Geometry on two-dimensional planes of this space can be of three types, Euclidean, Minkowski, and Galilean. Therefore, two-dimensional surfaces are also divided into three types according to the geometry on the tangent p

In spite of the model simplicity, striations are always found to exist regardless of the imposed barotropic mean flow. However, their properties are sensitive to the mean flow. Rhines jets move with the mean flow and are not necessarily striations. I

It is a local singularity, which differs from the ones considered by Dirac.

This article analyzes the complex relationships of places of memory from an interdisciplinary approach, to address the extractivist threats of the energy and mining sector and the interests of green business in the Galilea Forest. For this, the qualitative Participatory Action Research methodology was used, in collaboration with the social actors of the place, to strengthen the processes of territorial self-management in alliance with the University. Likewise, the symbolic understanding of architecture was examined further as a node of memory and collective cohesion. As a result, the "Center o

Abstract:

AbstractRecent studies have demonstrated the benefits of using electrodynamic tethers (EDT) for the exploration of the inner region of the Jovian system. Intense planetary magnetic field and reasonable environmental plasma density make the electrodynamic interaction of the conductive tether with the plasmasphere strong. The interaction is responsible for a Lorentz force that can be conveniently used for propellantless maneuvers and extraction of electrical power for on board use. Jupiter and the four Galilean Moons represent an exceptional gravitational environment for the study of the orbital

Si sostiene che esso è il resoconto di un esperimento preciso nel quale Galileo determina empiricamente i tempi di caduta per archi e corde (pendoli e piani) e quindi sviluppa un metodo per determinare il tempo di caduta per una data altezza, dato il quarto di periodo di un pendolo. L'analisi dimostra anche che Galileo fu consapevole del non isocronismo del pendolo (nonostante nelle sue pubblicazioni abbia affermato il cont

ABSTRACT The moons of giant planets are believed to form in situ in circumplanetary discs (CPDs). Here, we present an N-body population synthesis framework for satellite formation around a Jupiter-like planet, in which the dust-to-gas ratio, the accretion rate of solids from the protoplanetary disc, the number, and the initial positions of protosatellites were randomly chosen from realistic distributions. The disc properties were from 3D radiative simulations sampled in 1D and 2D grids and evolved semi-analytically with time. The N-body satellitesimals accreted mass from the solid component of

Abstract:

Galileo's imagination was quick to comprehend the importance of the 4 starry objects he observed near Jupiter in January 1610, not only for himself as a scientist but for our common understanding of the place of the Earth and our species in the cosmos. Even he, however, could not have imagined what those four objects would actually look like once humans got their first good look. Some 369 years the fast traveling Voyager 1 and 2 spacecraft provided that first good look during 1979, followed by an even closer look from the Galileo Orbiter beginning in 1996 through 2001.

Abstract:

The relationship between heavenly bodies and earthly behavior along with its importance took many centuries before the rigor scientific understanding enabled the true influences on Earth, such as its complicated motion and perceived other regularities in the behavior of earthly objects. One of these was the tendency for all things in one vicinity to move in the same downward direction according to the influence that is known as gravity property. Moreover, matter was observed to transform, sometimes, from one form into another, such as with melting of ice or vaporizing/cavitation of water, but

Abstract:

Galilean-type synagogues are monumental, basilical structures found in northern Israel that have long been dated, mainly on stylistic grounds, to the 2nd – 3rd centuries CE. This chronology is influenced by historical considerations – specifically, the notion that monumental synagogues must have been constructed before Jews came under Christian rule in the early 4th century. However, the stratigraphic contexts of the pottery and coins associated with the foundation of these buildings suggest they represent an architectural innovation dating to the 4th (especially the later 4th) to 6th centurie

This article explores one of the Galilee battles that took place during the 1948 War. During the Israeli ‘Operation Hiram’ of October 1948 the IDF forces occupied large parts of the central Galilee including the Palestinian Arab village of Jish. Until October 1948 the majority of the population of Jish was Muslim. Today the population is predominantly Maronite Catholic and Melkite Greek Catholic Christians, with a Muslim minority. However, unlike many of the destroyed Palestinian villages in this region, Jish managed to survive the Nakba despite the hard battle of Jish, although many of its Mu

Abstract:

We investigate the new special class of the finite string on a plane, after the reduction from the relativistic 4D case. The suggested special form of the phase space allows to define the extended Galilei group as a group of the spacetime symmetry for the considered system. The definition of the energy for the studied non-relativistic string through the Cazimir function of this group is suggested. The concept of the effective mass for the investigated dynamical system is introduced. The appearance of strong correlations between the degrees of freedom even on the classical level is discussed.
