The deep structure of the Iranian Plateau

High resolution structures of the lithosphere-asthenosphere system beneath a seismic profile in Iran are obtained by the simultaneous inversion of data from receiver functions and fundamental mode Rayleigh wave group velocity and validated by modeling Bouguer gravity anomaly data. The seismic data are gathered over a profile extending across Zagros, Sanandaj-Sirjan Zone (SSZ), Urumieh-Dokhtar magmatic arc (UDMA), Central Iran, Alborz-Binalud Mountain ranges and Kopeh Dagh Mountain ranges. The results confirm the presence of crustal roots at the north and south of Iranian Plateau where it meets the Arabian Plate and Eurasia. The high velocity lithosphere of the Arabian Plate gently plunges NNE-ward beneath Central Iran supporting the subduction of the continental lithosphere responsible for the seismicity of the area. The crust and lithosphere are thinner beneath Central Iran, where two low velocity structures are very likely related to magma sources of the UDMA and in east of Iran, around Lut block, where the volcanism shows calcalkaline subduction-related geochemistry. The crustal-lithospheric root to the north of the Iranian Plateau may represent the relict of a previous "cimmeric" subduction zone. Therefore the Iranian lithosphere-asthenosphere system could be the result of the coalescence of two separate subduction zones. © 2014 International Association for Gondwana Research

High resolution image of uppermost mantle beneath NE Iran continental collision zone

We invert 3775 relative P wave arrival times using the ACH damped least square method of Aki et al. (1977) to study upper mantle structure beneath the NE Iran continental collision zone. The data for this study were recorded by 17 three component broad-band stations operated from August 2006 to February 2008 along a profile from the center of Iranian Plateau, near Yazd, to the northeastern part of Iran on the Turan Platform just north of the Kopeh Dagh Mountains. The results confirm the previously known low velocity upper mantle beneath Central Iran. Our tomographic model reveals a deep high velocity anomaly. The surficial expressions of this anomaly are between the Ashkabad and Doruneh Faults, where the resolution and ray coverage are good. A transition zone in uppermost mantle is recognized under the Binalud foreland that we interpreted as suture zone between Iran and Turan platform. Our results indicate that Atrak Valley which is the boundary between the Binalud and Kopeh Dagh Mountains can be considered as the northeastern suture of the Iranian Plateau where Eurasia and Turan Platform under-thrust beneath the Binalud range and Central Iran

Effects of faculty members positive character and its indices on educational motivation of students at the University of Isfahan

Reaching high levels of success in institutions of higher education is deeply dependent on the character and behavior of their professors and instructors for they are the ones who have the power of expanding horizons of higher education actively. Therefore, the present study aims to investigate the effects of professors' character on the educational motivation of students at the University of Isfahan. This applied research is a descriptive- correlative study. The statistical population of the study included 13281 students at the University of Isfahan that 373 them whom were selected as the sample through random sampling. The data were collected through a standard researcher-made questionnaire whose content reliability was approved after experts' review. The validity of the questionnaire was estimated using Cronbach Alpha method at 0.91.  The data was analyzed through SPSS 20 computer application. The results revealed that the effect of character on educational motivation of students as the primary hypothesis of the study was significant. Yet, as its secondary hypotheses, the study failed to find a significant relationship between indices of character including wisdom, modesty and passion independently on educational motivation. However, the effect of other indices like honesty, courage, humor and compassion on educational motivation of the students was significant. Thus, it could be concluded that the higher the professors' characteristic indices of honesty, courage, humor and compassion, the more educationally motivated their students will be

Comparison of characteristic features and local recurrence in syndromic versus non-syndromic multifocal non-ossifying fibroma

Background: Multiple non-ossifying fibromas (MNOF) could be presented with other extraskeletal anomalies (syndromic) or not (non-syndromic). In this study, we aimed to compare characteristic features and local recurrence between symptomatic syndromic and non-syndromic MNOFs. Methods: Thirty-five patients with symptomatic MNOF were included in this study, comprised of 30 patients without the café-au-lait spot (non-syndromic) and five with café-au-lait spots plus other signs of neurofibromatosis type 1 (syndromic). Characteristic features of the patients and lesions were compared between syndromic and non-syndromic MNOFs. The lesions were treated with curettage and bone graft. The rate of local recurrences was also compared between the two groups of syndromic and non-syndromic MNOF. Results: Study population included 19 (54.3) males and 16 (45.7) females with the mean age of 7.63 ± 3.1 years (range 4�11). The mean follow-up of the patients was 65.6 ± 38.2 months (range 24�96). The lesion was bilateral in 13.3 of non-syndromic MNOFs and 80 of syndromic MNOFs. This difference was statistically significant (p = 0.01). After curettage and bone grafting, the lesion recurred in 6.7of non-syndromic MNOFs and 60 of the syndromic MNOF. This difference was statistically significant, as well (p = 0.01). No other significant difference was found between syndromic and non-syndromic MNOFs. Conclusions: The syndromic form of MNOF is much less prevalent and is associated with a higher rate of recurrence after surgical removal. Therefore, a more rigorous removal of the MNOF lesions might be necessary when presented in a syndromic context. © 2020 The Japanese Orthopaedic Associatio
