Novel Superpotentials for Supersymmetric Quantum Mechanics: A New Mathematical Investigation and Study  [PDF]
Alireza Heidari, Seyedali Vedad, Mohammadali Ghorbani
Journal of Modern Physics (JMP) , 2012, DOI: 10.4236/jmp.2012.34043
Abstract: The following article has been retracted due to the investigation of complaints received against it. Mr. Mohammadali Ghorbani (corresponding author and also the last author) cheated the authors’ name: Alireza Heidari and Seyedali Vedad. The scientific community takes a very strong view on this matter and we treat all unethical behavior such as plagiarism seriously. This paper published in Vol.3 No.4 304-311, 2012, has been removed from this site.
Symmetry breaking in mirror nuclei55 Co and 55Ni
S. Mohammadi
Iranian Journal of Physics Research , 2002,
Abstract: Yrast states in mirror nuclei 55Co and 55Ni have been populated with a radioactive ion beam using the Isotope Separator On-Line method. A shielded array of 7 Compton suppressed germanium detectors recorded reaction gamma-rays. For channel selection, an array of 128 independent silicon detectors was used to differentiate exit channels with different number of proton and alpha particles emitted. From gamma-gamma and gamma-particle coincidences, three lines in 55Co and one line in 55Ni was obtained for the first time
Some additional comments about the determination of p, the ratio between the real part and the imaginary part of the forward elastic amplitude, in hadron collisions at high energies

Semina : Ciências Exatas e Tecnológicas , 2004,
Abstract: The correct method of determination of ?, the ratio between the real and imaginary part of the elastic scattering amplitude in the forward direction, in the hadronic collisions at high energy, remains as an is still considered an open subject up till now. In this work we come back to discuss this problem and present two alternative fits for adjustment of the experimental data of d?/dt in the Coulomb – Hadronic Interference region are presented, consequently obtaining as well as the value of ?. Our proposals were tested with the data obtained in the polemic experiment accomplished in CERN in 1986 by the UA4/1 collaboration for the pp collision at s = 546GeV. Using these same data, we calculated the variable ? again and we found values much smaller than the original value of 0.24 ± 0.04, namely, 0.197 ± 0.020 and 0.189 ± 0.030.
Quantum Isomorphic Shell Model: Multi-Harmonic Shell Clustering of Nuclei  [PDF]
G. S. Anagnostatos
Journal of Modern Physics (JMP) , 2013, DOI: 10.4236/jmp.2013.45B011
Abstract: The present multi-harmonic shell clustering of a nucleus is a direct consequence of the fermionic nature of nucleons and their average sizes. The most probable form and the average size for each proton or neutron shell are here presented by a specific equilibrium polyhedron of definite size. All such polyhedral shells are closely packed leading to a shell clustering of a nucleus. A harmonic oscillator potential is employed for each shell. All magic and semi-magic numbers, g.s. single particle and total binding energies, proton, neutron and mass radii of 40Ca, 48Ca, 54Fe, 90Zr, 108Sn, 114Te, 142Nd, and 208Pb are very successfully predicted.

 

Method of Images to Study the Charge Distribution in Cases of Potentials Deviating from Coulomb’s Law  [PDF]
Abdulwahab K. Sallabi, Jamal A. Khaliel, Ali Sulaiman Mohamed
Journal of Electromagnetic Analysis and Applications (JEMAA) , 2014, DOI: 10.4236/jemaa.2014.64008
Abstract:

The method of images is used to study the charge distribution for cases where Coulomb’s law deviates from the inverse square law. This method shows that in these cases some of the charge goes to the surface, while the remainder charge distributed over the volume of the conductor. In accord with the experimental work, we show that the charge distribution will depend on the photon rest mass and is very sensitive to it; a very small value of the rest of mass of the photon will create deviation from Coulomb’s law.

Electromotive Force Generation with Hydrogen Release by Salt Water Flow under a Transverse Magnetic Field  [PDF]
Roberto De Luca
Journal of Modern Physics (JMP) , 2011, DOI: 10.4236/jmp.2011.210138
Abstract: By considering an electrolyte solution in motion in a duct under a transverse magnetic field, we notice that a so called Faraday voltage arises because of the Lorentz force acting on anions and cations in the fluid. When salt water is considered, hydrogen production takes place at one of the electrodes if an electric current, generated by Faraday voltage, flows in an external circuit. The maximum amount of hydrogen production rate is calculated by basic electrochemical concepts.
Pairing Effect on the Binding Energy Curve of N = Z Atomic Nuclei  [PDF]
Bernard Schaeffer
World Journal of Nuclear Science and Technology (WJNST) , 2013, DOI: 10.4236/wjnst.2013.33013
Abstract:

The saw-tooth phenomenon on the binding energy curve of N = Z nuclei is due to the low binding energy between the α-particles. It was suspected by Gamow to be of van der Waals type, found here to be deuteron bonds. The binding energy per nucleon, in absolute value, of an α-particle is larger than any other combination of 4 nucleons. Therefore, the binding energy per nucleon is low for odd-odd N = Z nuclei and maximum for even-even N = Z nuclei. The assumption of N = Z nuclei to be an assembly of α-particles and deuteron bonds predicts the binding energy of the 32 first N = Z nuclei with a rms deviation of 0.25 MeV.

Inter Seasonality of the Energy Fluxes in Brazilian Savana—Mato Grosso—Brazil  [PDF]
Leone Francisco Amorim Curado, José de Souza Nogueira, Luciana Sanches, Thiago Rangel Rodrigues, Francisco de Almeida Lobo, Marcelo Sacardi Bíudes
Atmospheric and Climate Sciences (ACS) , 2014, DOI: 10.4236/acs.2014.42025
Abstract:

Dynamics of flows of matter and energy these biomes are relevant to understanding of environmental processes that govern the biosphere-atmosphere interactions and between ecosystems. This study analyzed inter season and season of energy fluxes in Brazilian Savana through Bowen Ration Method. Results show differences in patterns LE in all season, LE predominant in wet while H in dry. This inversion in patterns of predominant components of the energy balance in wet and dry season because in wet season increase water content in soil and atmosphere due precipitation in this season providing more lost energy for atmosphere in shape LE through soil evaporation and plant transpiration, this results in LE and H in all season of the Brazilian Savana show higher variation in dynamics energy fluxes between surface and atmosphere, as well as energy partition in this biome. Statistics analyses presents than many climate variables influences LE and H in each season indicating complexity in this fluxes. More study is necessary to higher understand patterns energies fluxes in Brazilian Savana.

Low temperature magnetoresistive effects and coulomb blockade in La0.7Ca0.3MnO3 nanoparticles synthesis by auto-Ignition method  [PDF]
Aamir Minhas Khan, Arif Mumtaz, S. K Hassnain, A. Ul Haq
Natural Science (NS) , 2011, DOI: 10.4236/ns.2011.36069
Abstract: Electrical transport properties of the La0.7Ca0.3MnO3nanoparticles have been inves-tigated in the temperature range 300 to 9 K as a function of magnetic field. Samples were pre-pared by auto-ignition method. In low tempera-ture regime from 40 to 9 K, an increase in the resistivity has been observed. This effect is found to decrease as magnetic field is increased. It is assumed that these effects are due to the magnetic contacts between the nanoparticles.
