The motion of a satellite about a rotating triaxial body will be investigated, stressing on the case of slow rotation. The Hamiltonian of the problem will be formed including the zonal harmonic J2 and the leading tesseral harmonics C22 and S22. The small parameter of the problem is the spin rate ( ) of the primary. The solution proceeds through three canonical transformations to eliminate in su...

We investigate the dynamics of putative Earth-mass planets in the habitable zone (HZ) of the extrasolar planetary system OGLE-2006-BLG-109L, a close analog of the Solar System. Our work is inspired by the paper of Malhotra and Minton (2008). Using the linear Laplace– Lagrange (L–L) theory, they identified a strong secular resonance that may excite large eccentricity of orbits in the HZ. However...

A mutation is often thought of in negative terms, that is, as a damaged or altered gene that can no longer fulfil its purpose as intended. However if we reverse our view and consider the whole as the vehicle that is incapable of fulfilling its purpose then the mutation becomes a new possibility. For the purposes of this paper, religion in its traditional sense will be considered as the „faulty ...

We study the Boussinesq equation from the point of view of a multipletime reductive perturbation method. As a consequence of the elimination of the secular producing terms through the use of the Korteweg–de Vries hierarchy, we show that the solitary–wave of the Boussinesq equation is a solitary–wave satisfying simultaneously all equations of the Korteweg–de Vries hierarchy, each one in an appro...

We investigate the secular dynamics of a planetary system composed of the parent star and two massive planets in mutually inclined orbits. The dynamics are investigated in wide ranges of semi-major axes ratios (0.1–0.667), and planetary masses ratios (0.25–2) as well as in the whole permitted ranges of the energy and total angular momentum. The secular model is constructed by semi-analytic aver...

is religious commitment declining? is the form of religiosity changing in the society of mashhad? to find answers to these questions, we studied the various theories of secularization and determined its three levels. we defined individual secularization and its product; the secular attitude, and determined its dimensions and its indexes. next we measured the secular attitude. we then studied th...

The paper discusses and critiques some aspects of the controversy in bioethics concerning the mixing of human and animal materials for scientific research, including the science and technology of chimeras, cybrids, and human-animal hybrids, and the conceptual logic of evolutionists. It is argued that the logic of evolutionists explains why objections to the research are unconvincing, and conclu...

In this essay, I maintain that although atheism, minimally construed, consists simply of the belief there is no God or gods, atheists must embrace a secular worldview one kind another. Since they cannot be without worldview, develop an alternative to religious, especially theistic, worldviews which they, by implication, reject. Further, argue are, at very least, two options available and these ...
