Using of the generalized special relativity (GSR) in estimating the neutrino masses to explain the conversion of electron neutrinos  [PDF]
M. H. M. Hilo
Natural Science (NS) , 2011, DOI: 10.4236/ns.2011.34044
Abstract: In this work the Generalized Special Relativity (GSR) is utilized to estimate masses of some elementary particles such as, neutrinos. These results are found to be in conformity with experimental and theoretical data. The results obtained may explain some physical phenomena, such as, conversion of neutrinos from type to type when solar neutrino reaches the Earth.

M. H. M. Hilo, M. D. Abd Allah, Kh. M. Haroon, A. H. Abd Elrahman
Natural Science (NS) , 2012, DOI: 10.4236/ns.2012.45046
Abstract: Using the equation of motion expression in a curved space proper time is a useful method to explain the relation between the curvature of space-time and the potential of any field obtained. Taking into account the expression for the Hamiltonian density, the effect of fields, as well as the effect motion, on the mass, and, their effect on energy is found. The new expression of energy reduced to the ordinary Newton’s energy expression. It also explains the gravitational red shift.

H. G. I. Hamza, M. H. M. Hilo, R. Abd Elgani, R. Abd Elhai, Mubarak Dirar
Natural Science (NS) , 2014, DOI: 10.4236/ns.2014.617119
Abstract: In this study the electromagnetic theory and quantum mechanics are utilized to find the resistivity in terms of electric and magnetic susceptibility in which the electron is considered as a wave. Critical temperature of the wire at which the resistance vanishes is found. In this case the resistance being imaginary which leads the real part of the resistance to real zero at critical temperature and the material becomes super conductor in this case. If one considers the motion of electron in the presence of inner magnetic field and resistance force, a new formula for the conductivity is to be found; this formula states that the material under investigation becomes a superconductor at critical temperature and depends on the strength of the magnetic field and friction resistance, and the substance conductivity is found to be super at all temperatures beyond the critical temperature.
Effect of doping concentration on the performance of solar cell constructed from (Muscovite/TiO2/Dye/Al)  [PDF]
R. Abd Elgani, M. H. M. HILO, A. Al Hassan, M. D. Abd Allah
Natural Science (NS) , 2013, DOI: 10.4236/ns.2013.51009
Abstract:

Solar cells were fabricated from (Muscovite/ TiO2/Dye/Al), the effect of temperature, concen- tration and light intensity on the electrical prop- erties of (Muscovite/TiO2/Dye/Al) was studied. The relationship between current and voltage was found to be algorism, which is in agreement with the ordinary relation for solar cells. When dye concentration was increased the conductivity, fill factor and efficiency were also increased. This result is found to be in conformity with the theoretical relations. The small energy gaps for their samples show that they are semiconductors. The maximum efficiency obtained is 33.2%.

Using the tight binding approximation in deriving the quantum critical temperature superconductivity equation  [PDF]
R. Abd Elhai, M. H. M. Hilo, R. Abd Elgani, M. D. Abd Allah
Natural Science (NS) , 2013, DOI: 10.4236/ns.2013.58114
Abstract:

Superconductivity is one of the most important phenomena in solid state physics. Its theoretical framework at low critical temperature Tc is based on Bardeen, Cooper and Schrieffer theory (BCS). But at high Tc above 135, this theory suffers from some setbacks. It cannot explain how the resistivity abruptly drops to zero below Tc , besides the explanation of the so called pseudo gap, isotope and pressure effect, in addition to the phase transition from insulating to super-conductivity state. The models proposed to cure this drawback are mainly based on Hubbard model which has a mathematical complex framework. In this work a model based on quantum mechanics besides generalized special relativity and plasma physics. It is utilized to get new modified Schr?dinger equation sensitive to temperature. An expression for quantum resistance is also obtained which shows existence of critical temperature beyond which the resistance drops to zero. It gives an expression which shows the relation between the energy gap and Tc . These expressions are mathematically simple and are in conformity with experimental results.

Neutrino speed can exceed the speed of light within the frame work of the generlized special relativity and savckas model  [PDF]
Mubarak Dirrar, M. H. M. Hilo, R. Abd Elgani, A. M. A. Bakheet
Natural Science (NS) , 2013, DOI: 10.4236/ns.2013.56084
Abstract:

The speed of Neutrino particles is shown to be greater than that of light as shown by the OPERA neutrino experiment at the underground Gran Sasso Laboratory. The result of this experiment can be explained within the framework of the Generalized Special Relativity and Savickas model.

Impact of the light intensity variation on the performance of solar cell constructed from (Muscovite/TiO2/Dye/Al)  [PDF]
R. Abd Elgani, M. H. M. Hilo, M. D. Abd Allah, A. Al Hassan, R. Abd Elhai
Natural Science (NS) , 2013, DOI: 10.4236/ns.2013.510131
Abstract:

In this work, the influence of the light intensity as one of the parameters that control the solar cell is studied. The effect of the other main variables, such as temperature, rotation per Minuit of the spin coating instrument, and the samples concentration, was found to be in conformity with other results, but unfortunately the intensity of light does not increase the solar cell efficiency, and fill factor, by other words it was found to play only a secondary role.

Deriving of the Generalized Special Relativity (GSR) by Using Mirror Clock and Lorentz Transformations  [PDF]
M. H. M. Hilo, R. Abd Elgani, R. Abd Elhai, M. D. Abd Allah, Amel A. A. Elfaki
Natural Science (NS) , 2014, DOI: 10.4236/ns.2014.617117
Abstract: Einstein relativity theory shows its high capability of promoting itself to solve the long stand physical problems. The so-called generalized special relativity (GSR) was derived later, using the beautiful Einstein relation between field and space-time curvature. In this work we re-derive (GSR) expression of time by incorporating the field effect in it, and by using mirror clock and Lorentz transformations. This expression reduces to that of (GSR) the previous conventional one, besides reducing to special relativistic expression. It also shows that the speed of light is constant inside the field and is equal to C. This means that the observed decrease of light in matter and field is attributed to the strong interaction of photons with particles and mediates which causes successive absorption and reemission processes that lead to time delay. This absorption process makes some particles appear to move faster than light within the field or medium. This new expression, unlike that of GSR, can describe time and coordinate relativistic expressions for strong as well as weak fields at constant acceleration.

Abstract: Nova Delphini 2013 was identified on the 14th of August 2013 and eventually rose to be a naked eye object. We sought to study the behaviour of the object in the run-up to outburst and to compare it to the pre-outburst photometric characteristics of other novae. We searched the Pan-STARRS 1 datastore to identify pre-outburst photometry of Nova Del 2013 and identified twenty-four observations in the 1.2 years before outburst. The progenitor of Nova Delphini showed variability of a few tenths of a magnitude but did not brighten significantly in comparison with archival plate photometry. We also found that the object did not vary significantly on the approximately half hour timescale between pairs of Pan-STARRS 1 observations.
