We investigate the characteristics of monochromatic particles about a Kerr (rotating) black hole (BH) and their contributions to the observed soft X-ray flux of Fe Kα emission lines. We develop a thin-torus model to formulate the particles which are not restricted within the equa...

The variability of the horizontal component of magnetic field intensity from 7 stations within the Equatorial electrojet (EEJ) belt (±3° of the magnetic equator) has been investigated using year 2008 data measured from the Magnetic Data Acquisition System (MAGDAS) magnetometers....

The study of mechanical resistances twined to standards dispositions allows keeping a composition of CEB measured out 10% of cement and 2% of Tectona grandis sawdust. This composite material offers a higher strength compared to the one obtained with Afzelia sawdust. The method of...

Profile variations in the Ha and Hb lines in the spectra of the stars HD198478 and HD187982 are investigated from spectroscopic observations acquired in 2010-2011, 2013-2015 at the Cassegrain focus of the 2-m telescope at the Shamakhy Astrophysical Observatory. The spectral resol...

In a rather terse note, published in 1935, G.W. Hammar explained his brilliant experiment destined to put away, once and for all, the notion of “aether entrainment”. Certain physicists, such as Dayton Miller, insisted that the null result of the Michelson-Morley experiment and i...

Salt lakes and small – scaled salt production in Ebonyi State, Nigeria have long interesting history and the need to be informed of the radiological quality of the salt is essential to radiation measurement and protection agencies. Gross alpha and beta activity concentrations ha...

In this experimental study, we have determined both thermo-physical and mechanical properties of raw soil blocks stabilized with fiber straws. Also was studied, the influence of straw content incorporated in the blocks for both properties. Thermophysical properties are determined...

The present study deals with the MHD stagnation point flow of Nanofluid past a non-isothermal stretching sheet in porous medium. The presence of Brownian motion and thermophoresis effects yields a coupled nonlinear Boundary Value Problem. The sheet is assumed to be permeable. Sim...

In this paper, we have determined the free energy of a binary alloy for any order and it is showed that the number of equilibrium states of the system is obtained by the Taylor expansion to the 4-th order choice. We explicitly determine the stable states of alloy which are charac...
