http://purkh.com/index.php/tophy/article/view/175
<p>The thermodynamic properties of real physical systems are greatly influenced by the inter particle interactions. Recent experimental progress in trapping and cooling of molecular gases creates great interest in the study of gases with dominant dipole-dipole interactions with electric or magnetic dipole moments. In this paper we use mean field method to find out the non ideal equation of state and thermodynamic properties of a dipolar system.</p>K M UdayanandanSuresh T P

http://purkh.com/index.php/tophy/article/view/194
<p>The creation of high-power lasers has opened a new era in the development of basic research and cutting-edge technologies in various fields of practical application. All this is, first of all, due to the unique properties of laser sources of high-power coherent radiation. They include: a) high monochromaticity (i.e. a small width of the emission line), which offers new opportunities in high-resolution spectroscopy; b) high spatial and temporal coherence (i.e. the occurrence of light oscillations in a coordinated manner, resulting thereby in a distinct interference pattern), which gives a strong impetus to the development of holography and optical information processing methods; c) a relatively high specific energy that can be emitted by the laser, d) a possibility of varying the length of time during which the energy stored in the laser can be emitted in a wide range of durations: from continuous to femtoseconds; e) a possibility of variations in the temporal structure of radiation from tens of Hz up to tens of GHz; and f) a small divergence, which enables tight focusing. Due to these properties, the laser power density, which can affect the substance, reaches a giant value on the order of 10<sup>20</sup> W/cm<sup>–2</sup>. Consequently, it is possible to expose a substance to radiation whose power density exceeds all known today values characterizing natural and artificial sources. This fantastic opportunity has been thoroughly investigated in the recent decades by scientists from different countries. Clearly, by gradually increasing the laser energy and reducing the length of time during which that energy is emitted, it is possible to observe several stages of an interaction like this.</p>Victor V.

http://purkh.com/index.php/tophy/article/view/201
<p>A new principle of origin and the nature of the action of gravity forces are proposed. Forces of universal attraction have plane-symmetrical directions. On this basis, it becomes possible to reconsider certain regularities in natural science. The new principle of gravitation will allow to explain physical paradoxes, to improve methods of scientific research and some technological processes.</p>sergey A. orlov

http://purkh.com/index.php/tophy/article/view/212
<p>In this paper we report some properties of thin film photocells prepared on the basis of Al/p-CdS/n-CdS/Zn<sub>1-x</sub>Cd<sub>x</sub>S heterojunctions. These heterojunctions were prepared by the method of chemical and electrochemical deposition from solution in a uniform work cycle. The open-circuit photovoltage (U<sub>oc</sub>), short circuit-current density (I<sub>scc</sub>) and efficiency of the Al/p-CdS/n-CdS/Zn<sub>0.6</sub>Cd<sub>0.4</sub>S heterojunctions were 650 mV; 35 mA/cm<sup>2</sup> and 11%, accordingly. The I-U fill factor was 0.68. The value of U<sub>oc</sub> increases and I<sub>scc</sub> decreases by increasing of Zn in Zn<sub>1-x</sub>Cd<sub>x</sub>S material.</p>maarif Ali JafarovE.F NasirovS.A JahangirovaR.M Mammadov

http://purkh.com/index.php/tophy/article/view/225
<p>The investigations of the fractal structure and properties of the different geophysical elements is new and fast developing area of research among the geophysical society. The fractal properties of the earthquake clusters, faults and folds at different scale, even the plutonic bodies and other elements of the positive landforms are the most exploited areas of research. In our caste the special attention is paid to the gravity field (free-air anomalies) as the most expressive element of the surface elevated structures and their influence to the relief. The Balkan Peninsula is well known as the one of the most variable Earth’s surface elevation area in the world. The fractal properties of gravity field in such area could be useful to try to establish formal relationships to the surface elevation, as well as to prove the possibility to get some information about the self-organization and the origin of the mountain landforms in the same area.</p>Rosen Georgiev IlievTzanko TzankovBoyko Ranguelov

http://purkh.com/index.php/tophy/article/view/182
<p>In this research, we introduce and represent the modified Khater method on two basic models in the optical fiber. These two models describe the dynamics of the wave movement in the optical fiber. It is a new modification of new recent method which developed by Mostafa M. A. Khater in 2017. We implement this new modified technique on Schwarzian Korteweg de Vries equation and (2+1)-Ablowitz-Kaup-Newell-Segur equation. This modification of Khater method produces more closed solutions than many other methods. Schwarzian Korteweg de Vries (SKdV) equation has a closed relationship with (2+1)-Ablowitz- Kaup-Newell-Segur equation. Schwarzian Korteweg de Vries equation prescribes the location in a micro-segment of space and motion of the isolated waves in varied fields which localized in a tiny portion of space. It is a great and basic system in fluid mechanics, nonlinear optics, plasma physics, and quantum field theory.</p>Raghda A.M. AttiaDianchen LuMostafa M. A. KhaterOmnia M. Abd elazeem

http://purkh.com/index.php/tophy/article/view/152
<p>This study presents the numerical approximation method for the nonsingular fractional derivative known as the Caputo-Fabrizio fractional derivative on uniform and nonuniform mesh. It has been found that the accuracy of the utilized fractional derivative can be improved on nonuniform mesh compare to the uniformone. In contrast to the previous literatures, the accuracy of nonsingular fractional derivative is highly weighted by the fractional order and the memory kernel.</p>Norodin Rangaig
