Recent studies indicated that it is possible to obtain MSCs from peripheral blood by attachment ability to plastic surface. To evaluate adherent cells derived from peripheral blood, their expression profile and surface markers were investigated. The results of RT-PCR indicated that these cells expressed MECP2, SLITRK2, SLITRK4 as well as the neuronal markers Nestin, β III tubulin, NFM, MAP2 and NSE. In the present study, a panel of surface markers were analysed by flow cytometry. These cells display a fibroblast like morphology as well as known sources of MSCs. The results obtained from immune-staining represented that these cells were negative for CD14, CD45, CD15 and CD24, whereas they were positive for CD29, CD44, CD105, CD73, CD166 and CD184. Our data indicated that the peripheral blood could be considered as a source of MSCs with high yield.https://jsciences.ut.ac.ir/article_56994_cd3fafc8b23654aac6943bee814547c8.pdfUniversity of TehranJournal of Sciences, Islamic Republic of Iran1016-110427220160401Synthesis and Characterization of Copper(II)-Oxide Nanoparticles from Two Cu(II) Coordination Polymers11311756997ENM.

O. Box, 11365-4563, Islamic Republic of Iran.Journal Article20151021<span>Well-preserved miospore assemblages are recorded from the Late Ordovician (Katian-Hirnantian), Ghelli Formation in Pelmis-gorge at the north-eastern Alborz Mountain The palynomorphs were extracted from siliciclastic deposits which are well-dated by using of marine palynomorphs (acritarchs and chitinozoans). The encountered miospore assemblages consist of 14 genera (28 species: 26 cryptospores and 2 trilete spores). Six new cryptospore taxa are described: Rimosotetras punctata, Rimosotetras granulata, Dyadospora asymmetrica, Dyadospora verrucata, Segestrespora iranense and Imperfectotriletes persianense. The present findings contribute to improving knowledge of origin and onset of development of vegetative cover during the Late Ordovician. The recovery of diverse and abundant cryptospores in the Late Ordovician (Katian-Hirnantian) Ghelli Formation are probably related to increasing input of land-derived sediments during the global sea-level fall linked to the Late Ordovician glaciation, and tolerance of the primitive land plants in a wide range of climatic conditions. These miospore taxa were produced by earliest primitive land plants which probably grew close to the shoreline and washed in from the adjacent areas and produced high amount of miospores. The associated marine palynomorphs consist of acritarchs (13 genera and 18 species), chitinozoans (9 genera and 10 species), prasinophycean algae, scolecodonts and graptolite remains which are not discussed in detail herein. The established chitinozoan biozones of this part of Palaeozoic sequences are Armoricochitina nigerica, Ancyrochitina merga, Tanuchitina elongata and Spinachitina oulebsiri, suggesting the Late Ordovician (Katian-Hirnantian). These chitinozoan biozones are well-known only in peri-Gondwanan Domain, indicating that the study area has been part of this palaeo-continent during the Late Ordovician. </span>https://jsciences.ut.ac.ir/article_57002_f34606bf89b5f557cc5858ecc71a752c.pdfUniversity of TehranJournal of Sciences, Islamic Republic of Iran1016-110427220160401APG2: a New Version of APG, an Application for Amphibole-Plagioclase Geothermobarometry16116757003ENM.SayariDepartment of Geology, Faculty of Science, University of Isfahan, Isfahan, Islamic Republic of IranJournal Article20151213APG2 is a computer application designed for amphibole-plagioclase geothermobarometry.

In this paper the estimation of scale parameter under a bounded loss function, which is adequate for assessing quality and quality improvement, is considered with restriction to the principles of invariance and risk unbiasedness. An implicit form of minimum risk scale equivariant estimator and Bayes estimators are obtained. Fisher’s problem of the Nile as an example is included.https://jsciences.ut.ac.ir/article_57004_098efcfea12d14d2c1c50f822f764e4e.pdfUniversity of TehranJournal of Sciences, Islamic Republic of Iran1016-110427220160401Studying Transition Behavior of Neutron Point Kinetics Equations Using the Lyapunov Exponent Method17518657005ENM.Seidi1 Department of Physics, Faculty of Sciences, Ilam University, P.O.Box: 516-69315, Ilam, Islamic Republic of IranR.Khodabakhsh2 Department of Physics, Faculty of Sciences, Urmia University, P.O.Box:165-57153, Urmia, Islamic Republic of IranS.Behnia3 Department of Physics, Urmia University of Technology, P.O.Box:419-57157, Urmia, Islamic Republic of IranJournal Article20151003The neutron density is one of the most important dynamical parameters in a reactor. It is directly related to the control and stability of the reactor power. Any change in applied reactivity and some of dynamical parameters in the reactor causes a change in the neutron density. Lyapunov exponent method is a powerful tool for investigating the range of stability and the transient behavior of the reactor power. In contrast to the other linear stability methods, this method can be used for large perturbations and is not needed to construct Lyapunov function. In this work, the range of stability using Lyapunov exponent method is evaluated for neutron point kinetics equations with six-groups delayed neutrons. Here, effects of four set of applications, namely, step, ramp, sinusoidal, and temperature feedback reactivities on power reactor were investigated with Lyapunov exponent method. The results of qualitative analysis were compared with traditional methods and were in good agreement with other works.https://jsciences.ut.ac.ir/article_57005_d86b6ac033d30e208a5d3aea4a087a8d.pdf
