R.Noori-DaloiiDepartment of Medical Genetics, Faculty of Medicine, Tehran University of Medical Sciences, Tehran, Islamic Republic of IranF.KaramiDepartment of Medical Genetics, Faculty of Medicine, Tehran University of Medical Sciences, Tehran, Islamic Republic of IranJournal Article20140716<span>Isolation of cell free fetal DNA (cffDNA) from maternal serum usually leads to very low concentrations of DNA impeding further resolving through conventional methods of electrophoresis. Although several protocols have been described for capillary electrophoresis (CE) of double stranded DNA, they usually need using special polymers or coated capillaries which degrade over time. Herein, we proposed a new and very simple protocol using uncoated fused silica capillary for CE of cffDNA purified from serum of pregnant women. The proposed protocol was able to determine the presence of small fetal DNA fragments and it also confirmed the optimization of sonication performed on purified cffDNA samples. </span>https://jsciences.ut.ac.ir/article_52611_f8f4bd04c906fd07505e06db59bfa5de.pdfUniversity of TehranJournal of Sciences, Islamic Republic of Iran1016-110425420141201Genetic Diversity and Differentiation of Secale strictum Accessions Based on Phenotypic Traits and Seed Storage Protein ProfilesThe genetic diversity of nine wild Secale strictum accessions was studied using seed storage protein profiles and phenotypic traits.

In our study,various phenols and ethyl acetoacetate compound in which we used silica-supported boron sulfonic acid [SiO2/B(SO4H)3] as a new, highly efficient and tri-functional inorganic Brønsted acid catalyst were processed under solvent-free condition and thermal. The catalysts were separated easily from reaction mixture, regenerated after a simple activation step and reused at least six times without significant loss in catalytic activity. The most significant features of this procedure are:short period of conversion and excellent yields, simple experimental procedure, environmentally benign, the elimination of corrosive liquid acids and green aspects by avoiding toxic conventional catalysts and solvents.</span>https://jsciences.ut.ac.ir/article_52618_9c0a8ad5c8b28740f3fa36184dbd0d06.pdfUniversity of TehranJournal of Sciences, Islamic Republic of Iran1016-110425420141201Hydrothermal synthesis of cobalt oxide nanoparticles: Its optical and magnetic properties33934352619ENM.YarestaniDepartment of Chemical Engineering, College of Engineering, Shahrood Branch, Islamic Azad University, Shahrood, Islamic Republic of IranA.D.KhalajiDepartment of Chemistry, Faculty of Science, Golestan University, Gorgan, Islamic Republic of IranA.RohaniResearch institute of Petroleum Industry, the west entrance toAzadi stadium, Olympic Blv., Tehran, Islamic Republic of IranD.DasDepartment of Chemistry, The University of Burdwan, Burdwan, West Bangal, IndiaJournal Article20140421Cobalt oxide (Co3O4) nanoparticleshave been synthesized by hydrothermal method using mixture of cobalt(II)chloride, Triton X-100 and KOH in an autoclave at 180 °C for 6 h followed by heating at 400 ºC for 3 h in air.

Since the studies show that faults near the water resources have a critical effect on the concentration of radon, Kouhbanan active fault zone, to find water resources with high radon concentration was chosen for the following investigation. Water samples were taken from all of the 39 drinking water springs and Qanats in the Kouhbanan region, both in the summer and winter. Its length is 280Km and is aligned from Bahabad city in north-west to the Kerman city in south-east. Some evidence of the activity of this fault system are young morphotectonic structures and earthquake events along of this faults. To determine the content of sample’s radon, radon detector (RAD7) was used. In six out of water samples, radon levels was more than proposed emission 11.1kbm-3(MCL) by Environmental Protection Agency (EPA). The average annual effective dose in 2 regions is more than reference level of the European Union Council and world health organization (0. 1mSva-1) according to the average effective dose for ingestion of radon in water (0.002mSva-1) and inhalation (0.025mSva-1) by United Nations Scientific Committee on the Effective of Atomic Radiations. This study has concluded that the mean effective dose for ingestion and inhalation of radon in Kouhbanan fault zone, is greater than the amount recommended for water samples in 6 region.https://jsciences.ut.ac.ir/article_52622_5308899aa963aa09c1f22f7b8d38cdac.pdfUniversity of TehranJournal of Sciences, Islamic Republic of Iran1016-110425420141201Early Miocene (Burdigalian) Gastropod Faunas of Vareh Zard section, North of Pole-Dokhtar, (Lorestan, Iran)35736752623ENI.Maghfouri MoghaddamDepartment of Geology, Faculty of Sciences, Lorestan University, Khorram – Abad,Islamic Republic of IranJournal Article20140621A total 7 species and 13 genera of marine gastropod assemblages are reported for the first time from the Varehh Zard section (Asmari Formation), north of Pole Dokhtar, Lorestan Basin. The section under study, the Asmari Formation, lies between the Shahbazam Formation at the base and Gachsaran Formation at the top. According to the distribution of index foraminifera, the Asmari Formation is Early Miocene (Aquitanian-Burdigalian) in age. In general, gastropod assemblages have been observed in the upper part of Asmari Formation (Burdigalian). The Miocene and even Oligocene gastropod faunas, relatively similar to the Vareh Zard section, reported from Tethys and Proto- Indo- Pacific Ocean, indicate that a passage was open during this interval. In this study, Oostrombus auricularius, Anazola elavula, Conus diversiformis, Turbo thouvignoni, Campanile pseudoobeliscus, Cassis mamilliaris, Psudophasianus elatus, Paroxystele, Ampullina sp., Architectonica cf. carocollata are described with special emphasis on their distribution in the Tethys and adjacent bioprovinces. Lyra sp., Cerithium rude and Ampullospira sp. are restricted to the Proto- Indo- Pacific Ocean.https://jsciences.ut.ac.ir/article_52623_ea22af340fd93a58ddb7496ae8e83013.pdfUniversity of TehranJournal of Sciences, Islamic Republic of Iran1016-110425420141201Subpullbacks and Po-flatness Properties of S-posets36937752624ENA.GolchinDepartment of Mathematics, Faculty of Sciences,University of Sistan and Baluchestan, Zahedan, Islamic Republic of IranL.NouriDepartment of Mathematics, Faculty of Sciences,University of Sistan and Baluchestan, Zahedan, Islamic Republic of IranJournal Article20140416In (Golchin A. and Rezaei P., Subpullbacks and flatness properties of S-posets. <em>Comm.

In this paper, we present some graph theoretical properties of g-noncommuting graph. Specially, we investigate about its planarity and regularity, its clique number and dominating number. We prove that if G, H are isoclinic groups with |Z (G)|=|Z (H)|, then their associated graphs are isomorphic.https://jsciences.ut.ac.ir/article_52625_d10ebf26020ddfc9803c7628524add3d.pdf
