They range from 22km to 38km. The deepest CDP values are observed in the Black Sea basins where the sediment thickness is high, while the shallowest values are observed in the middle Black Sea ridge, and in the thin sedimentary regions of the coast. The Central Black Sea ridge generally ranges from 22 to 28 km. From the CDP values, the heat gradient and corresponding heat flow values were also obtained. Heat flow values of the Black Sea basin range from 22 to 41mW/m2. When the relationship between the deep faults and gas leaks with the heat flow is examined, it is observed that the possible deep fault zones and gas migration places correspond to a higher heat flow value than the average heat flow.","PeriodicalId":377724,"journal":{"name":"Physics & Astronomy International Journal","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127969395","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The images of these diffeomorphisms in G/H , are 2-form of curvatures that can be induced to each class of the G/K . Then using the K− invariant connection of this homogeneous space, the curvature can be determined as a regular representation that admits a finite discomposing of irreducible sub-representations of finite type, accord with the generalizing in dimensions of the Gauss-Bonnet theorem and the generalized Radon transform to obtain curvature through of co-cycles of the image of the corresponding space. Such irreducible sub-representations will be isotopic components of the certain smoothly embedded image in a manifold modelled this last, by a generalized function space. Likewise, through these realizations we have the curvature integrals as dual case of their field equations. Finally, using the complex Riemannian structure of our model of the space-time, and the K− invariant G− structure of the orbits used to obtain curvature, are obtained as consequences of the diffeomorphisms the field equations to the energy-matter tensor density in each case of the gravitational field. Of this manner, is determined their energy-mass tensor density as an integral which represents the energy spectra of the curvature when this is obtained in duality to the homogeneous field equations to the Riemann tensor Rμν−12gμν R.","PeriodicalId":377724,"journal":{"name":"Physics & Astronomy International Journal","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125326349","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, a brief theory is given to explain the results, with a short reference to both boundary phenomena in thermonuclear reactors and low pressure plasma of glow discharges, so that to reveal the similarities and differences of those two cases. An extensive examination of the treated objects by XRD method gives results, in agreement with theoretical predictions.

{"title":"Real magnetic charges as a negation of the electric magnetism Maxwell and electrified Dirac’s monopole","authors":"Sizov Ra","doi":"10.15406/paij.2018.02.00043","DOIUrl":"https://doi.org/10.15406/paij.2018.02.00043","url":null,"abstract":"The main reasons that real magnetic charges were \"buried alive\" in modern theories are physics of their confinement in atoms and substance which is radically different from the confinement of electrons, as well as the vicious electromagnetic theory of Maxwell. This theory which should be referred to as Maxwell's electric magnetism is the result of superficial perception by the Great Physicist of the famous Oersted's Experience when only external factors of Experience were taken into account: the electric current and the magnetic field around the conductor. It was with Maxwell's \"light hand\" that electrons moving in the composition electric current were erroneously declared to be the direct sources of the magnetic field what on 145 years has \"deprived\" the magnetic charges, which make up about half of the spinor particles in real World of the opportunity to engage its professional activities. It is important to note that the real physical processes taking place in the body of a conductor with an electric current as in Maxwell's time, so and until now, as this not paradoxically, remain outside beyond our detailed knowledge. Maxwell's electric magnetism can be represented as the \"cancerous tumor\" in the \"body\" of physical science the metastases of which struck, virtually, all the directions of the fundamental physical theory. With taking into account the historical conditions of formation and the scales of the negative impact on civilization, the vicious electromagnetic concept of Maxwell is quite adequate with to such surface-primitive concepts as Flat Earth or near-Earth rotation of Sun. As a result of all these circumstances, many useful and effective technical projects that could improve the quality of people's lives, as well as expand the technological capabilities of our civilization could not take place. So, for example, in the absence of magnetic charges in physical representations was impossible to find out the real physics of the gravitational field. Therefore it turned was not possible to implement such important project both the technical Gravitational Levitation in which can use the inexhaustible, stable and environmentally friendly energy of the gravitational field directly. It should be noted that the project of technical Gravitational Levitation is just one of many missed opportunities that were closed as a result of the negative exposure of Maxwell's electric magnetism on the physical science. In 1931 P. Dirac proposed his the famous theory of magnetic monopole. But in order for this monopole to emit a magnetic field, this field must first be produced with the help of an electric current in the filamentary solenoids of Dirac. The Dirac monopole, given the all circumstances of its formation, can be called an electrified magnetic pole, based, implicitly, on the same vicious electromagnetic conception of Maxwell.","PeriodicalId":377724,"journal":{"name":"Physics & Astronomy International Journal","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132722897","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition we carry out similar procedure to reconstruct the field potentials for tachyonic field for the same models. In this note, we reconstructed the field potentials for some known models e.g. constant deceleration parameter model, linearly varying deceleration parameter model and a model based on a specific parametrization of Hubble parameter.
