Geometric quantities in all orthogonal curvilinear co-ordinates are built upon Euclidean geometry. This geometry is founded on a well known metric tensor called the Euclidean metric tensor. Riemannian geometry which is assumed to be more general than the Euclidean geometry was fo...

The one-dimensional superlattice (SL) based on a monolayer graphene modulated by the Fermi velocity barriers is considered. We assume that the rectangular barriers are arranged periodically along the SL chain. The energy spectra of the Weyl-Dirac quasi-electrons for this SL are c...

Measurement of electric field strength, magnetic field strength and power density were carried out using two instruments, electro smog meter (model TES -92) and ELF detection meter (model 480823) at an interval of 2 m starting from the base of the source. The maximum electric fie...

Planetary gears are identified as compact alternatives to fixed-axis gear trains and show more complicated dynamical behavior due to the nonlinearity induced by the interaction between backlash and tooth defects. The majority of current publications are based on theoretical model...

Aims: An analysis is presented to investigate the effects of suction and thermal radiation on the unsteady convective hydromagnetic flow and heat transfer in a third grade fluid over an infinite vertical plate. The plate is porous to allow for possible wall suction. Viscous dissi...

The signs of stability of the sea ice thickness from the latest Cryosat-2 results for the Arctic sea ice thickness are consistent with the Lower Troposphere Temperatures (LTT) and the sea ice extension results available since 1979. In the longer term, the current Arctic climate i...

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...
