The CR-39 solid state passive nuclear track detector is a popular method to measure charged particle such as alpha and protons and uncharged particles such as neutrons, due to its low cost, robustness, track permanence, and insensitivity to gamma, X-ray, beta and electromagnetic...

Ignition of cryogenic engines of space launchers is usually preceded by a transient phase during which feeding lines of the combustion chamber are swept by an inert gas. This sweeping flow may be prolonged for several milliseconds while propellants injection begins. Despite the f...

In this Brief Communication scalar length-scale and time-scale distributions are proposed to determine by considering the statistics of the scalar field and its gradient. For this purpose, a relationship between the scalar length-scale probability density function and the joint p...

Following the discovery of Higgs Bosons (H) with a mass of around 126 GeV/c2, it is hypothesized in this study that the gauge bosons, which are theoretically predicted to be gravitons in the mass interaction, may be produced by H, just as photons are produced in the case of elect...

Albert Einstein found that, for two particles coming from the same source, when the state of one changes, that of the other may change at the same time, no matter how far they are apart from each other. This superluminal quantum entanglement phenomenon totally violates both the s...

An enhanced of the (G'/G) -expansion method combined with Liu's theorem is proposed to construct new exact solutions of the nonlinear (1+1)-dimensional Drinfel'd-Sokolov-Wilson equation (DSW). As a result, more and new general exact solutions are obtained including hyperbolic fun...

The monocrystals InGaSe2 were grown by Bridgeman-Stockbarger method. The current-voltage characteristic was studied in the rectangular form samples of sizes 7x1x1 mm3. In and Cu served as contacts. The current supplying the ends of rectangular samples is oriented so that the cur...

The First and Second Zagreb indices were first introduced by I. Gutman and N. Trinajstić in 1972. It is reported that these indices are useful in the study of anti-inflammatory activities of certain chemical instances, and in elsewhere. Recently, the First and Second Multiple Zag...

By using a Coulomb potential, modified by the interaction between the magnetic moments of the electron and proton, we have calculated the energy levels of the hydrogen atom. We have obtained fine and hyperfine structure as well as the Lamb shift. All these effects are obtained fr...

We verify some assertions in the prequel to this paper, in which certain functions which are referred to as proximity functions were introduced in order to study Dirichlet-type approximations in normed divisible groups and similar groups that enjoy a form of divisibility, for ins...

The mass in Einstein’s energy-mass equivalence equation has two possible interpretations, whether it is limited to the invariant mass, or it applies to all energy. This paper argues that all of the energy (kg m2 s−2) has a mass (kg: a degree of weight and inertial resistance). Th...

The formula for the gravitational force inside a spherical body is derived, as well as for the Newtonian force of attraction between bodies from the standpoint of the gravitons’ model. The parameters of the graviton field are estimated, including its energy density, energy flux a...

We studied the microwave absorption of multi-walled carbon nanotubes (MWCNTs)-epoxy composites over a continuous frequency range in R-band (26.5 – 40 GHz). The outer diameters (OD) of the MWCNTs were in the 10 – 20 nm range. We measured and analyzed the microstructures, dielectri...
