We analyse the relation between activity cycle length and Rossby number collected a sample of 44 main sequence stars with well-known periods rotation periods. find linear behaviour in double-logarithmic period. The bifurcation into long short period branch is clearly real but it depends, empirically, on colour index B-V, indicating physical dependence effective temperature position sequence. Fu...

in religious thought, the miracle as a phenomenon is one of the most important reasons for proving prophethood. there are two broad views among islamic thinkers about the type of indications of miracles to prove prophethood. some consider the indications of miracles as rational ones. in contrast, some others hold that there is no logical connection between a miracle and its implied referent and...

The use of steel flush end-plate moment connection is practiced in the construction of the light steel frames around the world particularly in parts of Europe and US. In the past most research was concentrated on studying the behavior of the flush end-plate connection subjected to only monotonic type loadings. The majority of that research carried out such investigation through experimental pro...

We show an analogue of the Lorentzian splitting theorem for weighted Lorentz-Finsler manifolds: If a Berwald spacetime nonnegative Ricci curvature satisfies certain completeness and metrizability conditions includes timelike straight line, then it necessarily admits one-dimensional family isometric translations generated by gradient vector field Busemann function. Moreover, our formulation in t...

Abstract Finsler metrics are direct generalizations of Riemannian such that the quadratic indicatrices in tangent spaces a manifold replaced by more general convex bodies as unit spheres. A linear connection on base is called compatible with metric if induced parallel transports preserve Finslerian length vectors. manifolds admitting connections generalized Berwald Wagner (Dokl Acad Sci USSR (N...
