On Wolfgang Pauli's most important contributions to physics  [PDF]
Norbert Straumann
Physics , 2000,
Abstract: After some brief biographical notes, Wolfgang Pauli's main contributions to general relativity, quantum theory, quantum field theory, and elementary particle physics are reviewed. A detailed description is given how Pauli descovered - before the advent of the new quantum mechanics - his exclusion principle.
From Highly Structured E-Infinity Rings and Transfinite Maximally Symmetric Manifolds to the Dark Energy Density of the Cosmos  [PDF]
Mohamed S. El Naschie
Advances in Pure Mathematics (APM) , 2014, DOI: 10.4236/apm.2014.412073
Abstract: Starting from well established results in pure mathematics, mainly transfinite set theory, E-infinity algebra over operads, fuzzy manifolds and fuzzy Lie symmetry groups, we construct an exact Weyl scaling for the highly structured E-infinity rings corresponding to E-infinity theory of high energy physics. The final result is an exact expression for the energy density of the cosmos which agrees with previous analysis as well as accurate cosmological measurements and observations, such as COBE, WMAP and Planck. The paper is partially intended as a vivid demonstration of the power of pure mathematics in physics and cosmology.
Proposal of the Electromagnetic Structures of the Most Important Particles from Decays  [PDF]

Research & Reviews: Journal of Pure and Applied Physics , 2016, DOI: -
Abstract: Recently, it was published the book “Electromagnetic Unification of Four Forces” (ISBN978-3-659-76798-2), compiling the progressions in physics made by the world people, manifested in television while led notably by me and the Members in the world satellite networks from India, Zhejiang and USA. It was achieved many important progressions, such as the spatially localized electromagnetic mass structure; the electromagnetic multi-hairy structure; the electromagnetic orienting force; the thermodynamic strong force from electromagnetic multi-hairy hybrid; the weak processes from hybrid split; the gravitational force as electromagnetic curving and shifting red from electromagnetic orienting force; and so on; electromagnetic unifying the four forces. It was also determined the structures of photon,positron/electron, π mesons, μ leptons and neutrinos. In this article, from these achievements and decay products, it is attempted to further propose the electromagnetic structures of particles most important in physics, with conservation of energy (mass), charge and spin. It is classified the combined baryons into those based on proton such as the proton, neutron, Λ0 baryon,∑ baryons, and Ξ baryons; those based on kaons from colliding pieces such as the kaons, η baryons, charm quarks, and bottom quarks; those containing the W/Z bosons with the wavelength equivalent to hybrid interval, such as the W/Z/Higgs bosons and top quarks. Besides, it is pointed out that the τneutrino can adjust the angle between the adjacent hybrid areas in natural atomic nucleus. For the convenience of physicists to refer to, it is listed these electromagnetic structures into tables.
Strichartz estimates for Schr?dinger equations with variable coefficients and potentials at most linear at spatial infinity  [PDF]
Haruya Mizutani
Mathematics , 2011,
Abstract: In the present paper we consider Schr\"odinger equations with variable coefficients and potentials, where the principal part is a long-range perturbation of the flat Laplacian and potentials have at most linear growth at spatial infinity. We then prove local-in-time Strichartz estimates, outside a large compact set centered at origin, expect for the endpoint. Moreover we also prove global-in-space Strichartz estimates under the non-trapping condition on the Hamilton flow generated by the kinetic energy.
`Zero-spin-photon hypothesis' finds another important application: Could possibly solve the `infinity-problem' of QED without the need of renormalization  [PDF]

Physics , 2009,
Abstract: `Zero-spin-photon hypothesis' as proposed in an earlier paper [1] states that: `due to inevitable consequence of the second-law of thermodynamics and spin-conservation, the `zero-spin-photon' is generated in pair-production process (of elementary particles), which decays into neutrino and antineutrino'. The zero-spin photon hypothesis explains [1] several riddles of physics and universe. In the present paper, it is shown that `the zero-spin photon hypothesis' when incorporated into the higer-order Feynman diagram (with a closed-loop) could possibly solve the half-a-century-old and famous `infinity-problem' of QED, and thus could avoid the need of the so called `re-normalization' procedure.
Evolution of the Spanish media agenda (1980-2010). Longitudinal analysis of the front pages of two of the most important Spanish newspapers  [cached]

Revista Latina de Comunicación Social , 2012,
Abstract: The newspaper front page is a preferential media space where the journalistic selection and hierarchy are explicitly reflected. This article presents the results of a longitudinal study of the evolution of the Spanish media agenda, based on the analysis of two of the most important Spanish newspapers: El País and Abc, which have different editorial lines. The examination of these newspapers focuses on the identification of the main issues, actors, territories and degree of homogeneity of their main front-page news stories. The study of the evolution of the front-page agenda of these newspapers covered a three-decade period, from 1980 to 2010. A total of 800 news items were subjected to content analysis for this study. The results demonstrate, on the one hand, that there is a significant presence of issues and actors related to institutional policy and, on the other hand, that the Spanish press lacks an international perspective and is focused on national current affairs.

无机材料学报 , 2009, DOI: 10.3724/sp.j.1077.2009.00873
Abstract: Transparent ceramics is one of the most important materials with combined properties of structural and functional ceramics. The development of transparent ceramics is based on the research and development of nano sciences and technology, and of advanced ceramic processing sciences and technology. It will be the key materials for national economic development and defense necessary with high technology needed. At the same time, the process of ceramics from traditional opaque to translucent and to transparent will refer to many basic science issues, especially, the relationship between microstructure (including pores, grain boundary, grain size, morphology and so on) and photophysical properties of materials is still not clear. Therefore, as one of the main developing field of inorganic materials, the development of transparent ceramics needs joint efforts from chemistry, physics, laser, and material scientists together. The current advance of transparent ceramics is reviewed in this paper.

Abstract: The purpose of this study is to determine the opinions of preservice teachers about what the 4.grade students should learn in science and technology lesson who takes the subject for the first time. In this aim, according to preservice teachers, the question, what the most important subject is, which the 4. class students should learn, and its reasons, is asked. Universe of this study is consist of 3th. grade students of Candidate Teaching of Ahi Evran University. Also, the sample of this study is formed by the 71 students who are chosen randomly. Findings from this study are investigated as a descriptive, then these are classified the areas of biology, physic, and chemistry, lastly, these findings are investigated in the area of units. According to answers of candidates, it is mentioned that the students should learn biology at most, and then they should learn physic and chemistry. Their reasons are presented with the teacher’s own descriptions and details. The opinions of candidates and elementary school students have similarities. Both teachers and students share the same ideas of the most important subject is biology, and then chemistry and physics, which should be learned. The subjects, which the students are curious about, and the teachers want to teach confirm the principle of from the close to the far and from the concrete to the abstract.
