Marls of Iran based on minerals solvability are divided into two types: Evaporative and non-evaporative which have Special features and have been distributed in Tehran province. Formations and units of geology are important in sediments production and distribution marl units. In Tehran province, from the geological point of view, there is a combination of Alborz and Central Iran sedimentary units that &nbsp;based on maps geology information, on a scale of 1: 100000 and 1:250000 such as Tehran, Semnan, Amol, Ghazvin-Rasht, Marzanabad (Chalus) the geology formations and units exist often. There isn’t any gap in geology maps. Often marl geology formation and units such as Karaj, Ziarat, upper red and under red formation, are Cenozoic age and has been distributed in Tehran province North. Based on studies and this research geology marl Formations and units have been effective about percent 10 on sediment production and quaternary distribution in Tehran province.</p> </blockquote> Rahman Sharifi Mahmoud ‎ Nikkhah Shamirzadi ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc/4.0 2018-12-29 2018-12-29 8 4 91 95 10.14331/ijfps.2018.330119‎ Innovative extracting of optimum operational diagrams for a CW sealed CO2 laser based on the evolutionary genetic algorithm http://fundamentaljournals.org/index.php/ijfps/article/view/pdf <blockquote> <p style="text-align: justify;"><sub><img title="free website hit counter" src="http://www.free-website-hit-counter.com/c.php?d=5&amp;id=121001&amp;s=16" border="0"></sub>&nbsp;&nbsp;<small></small><strong>Views&nbsp; </strong></p> <p>Some innovative diagram for the optimum parameters in operation of a sealed CW CO<sub>2</sub> laser was extracted by using the evolutionary genetic algorithm.

Inner and covered outer surface area of molecules are the outstanding inventions related to gas behavior. The exertion of infrared wave force on the covered outer surface area of tiny particles and the corresponding effect on the inner surface of a gas container is the real cause of the gas behavior. We can independently explain all kind of behavior of gases with the help of the conception of the inner force and internal force. We can clarify the isothermal and adiabatic behavior of gases, show the relation between heat and force. It is most significant finding, the specific heat of an identical gas in the isochoric and the isobaric process is not different but same as the inner force in both methods is same.</p> Sankar Palchoudhury ##submission.copyrightStatement## https://creativecommons.org/licenses/by-nc/4.0/ 2018-06-16 2018-06-16 8 4 79 82 10.14331/ijfps.2018.330116 The influence of pulsed CO2 laser irradiation on the optical ‎properties of PMMA http://fundamentaljournals.org/index.php/ijfps/article/view/ijfps.2018.330115 <p>&nbsp;<img title="free website hit counter" src="http://www.free-website-hit-counter.com/c.php?d=5&amp;id=121098&amp;s=129" border="0">&nbsp; &nbsp;&nbsp;<strong><small>Views</small></strong></p> <p>In this paper, effect of the pulsed CO2 laser irradiation on optical properties and surface morphology of PMMA was investigated. The samples were irradiated by a CO2 pulsed laser with the wavelength of 9.55 micron and the pulse duration of about 100 ns. UV-Visible spectroscopy and Scanning Electron Microscopy (SEM) were used for investigating the change in absorption, reflection, refractive index and surface morphology, respectively.</p> <p>&nbsp;</p> Sahar Sohrabi ‎ Mitra Vesal‎ Hedieh Pazokian Mahmoud Mollabashi‎ ##submission.copyrightStatement## https://creativecommons.org/licenses/by-nc/4.0/ 2018-06-12 2018-06-12 8 4 74 78 10.14331/ijfps.2018.330115
