Research ArticleOpen accessIn the keywordsEffect of Partial Orientation in [100] Direction on the Magnetic Properties of Co-Ferrite Prepared from Nano ParticlesH. M. El-SayedChemical co-precipitation method was used for the preparation of Co-ferrite nano particles. The particle size was about 18 nm. A magnetic anisotropy of Co-ferrite could be increased by applying an external magnetic field during the pressing of the nano particles before the final sintering. This anisotropy enhanced the squareness and the coercivity of investigated samples. …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 7,220 accessesView PDFCite
Research ArticleOpen accessIn the abstractHazards from Pyroclastic Density Currents at Mount Bamenda (West-Cameroon, Cameroon Volcanic Line): Mapping and Assessment by AMS MethodMerlin Gountié Dedzo, Pierre Kamgang, Emmanuel Njonfang, Ghislain Zangmo TefogoumHazards related to pyroclastic density current continue to raise victims on many volcanoes in our planet. The Cameroon is not spared to this type of hazard because deposits of pyroclastic flows and surges are found on Mount Bamenda; products of this volcano are relatively young (27-0 Ma). Besides Mount Bamenda, Mounts Bambouto and Oku are the only volcanoes located in … …Current Research in Geoscience, Vol. 5, Issue 2 · 15 Oct 2015 · 7,871 accessesView PDFCite
EditorialOpen accessIn the abstractProblems of Ultra-High Energy Cosmic RaysAnna V. UrysonCosmic rays are energetic particles coming to the Earth from space. They bombard the atmosphere producing cascades of particles that spread over a large area when they reach the ground. Cosmic ray energies vary in the wide band from about 108 eV up to few 1020 eV. It is established that most particles with energies of ~ (108-109) eV come … …Space Science International, Vol. 2, Issue 1 · 6 Dec 2014 · 13,854 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordAbsolute Flux Comparison of Magnetospheric ParticlesMiah M. AdelProblem statement: The calculation of magnetospheric particle flux by dividing the particle count rate by the instrument geometric factor does not take into account the anisotropic pitch angle distribution function. A comparison of particle fluxes measured by different instruments fail to lead to the right comparison. To circumvent the omission of anisotropy of the pitch angle distribution and to make … …Physics International, Vol. 3, Issue 1 · 26 Mar 2012 · 7,674 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordElectrical, Structural, Magnetic and Transport Properties of Zn2 Ba Fe16 O27 Doped With Cu2+D. M. Hemeda, O. M. HemedaSeries of polycrystalline samples of Zn2-x Cux Ba Fe16 O27 were prepared by usual ceramic methods, where (x=0.0, 0.4, 0.6, 0.8, 1.0, 1.4) . X-ray analysis were obtained at room temperature using Coka with λ = 1.790A0 confirmed the presence of W-type hexaferrite phase structure . Saturation magnetization and hysteresis loops curves measurements at room temperature were studied as a … …American Journal of Applied Sciences, Vol. 5, Issue 4 · 30 Apr 2008 · 6,902 accessesView PDFCite
