In this research, for the first time Nb and Ge were doped into titanosilicate nanoparticles up to 25% simultaneously. Crystalline
phases and morphology of the synthesized samples were studied by X-ray diffraction (XRD) method and scanning electron microscope
(SEM), respectively. Elemental analysis of the samples was performed using X-ray fluorescence (XRF) and Energy dispersive
X-ray (EDX) techniques. Surface area of the samples was measured by BET method. Ion exchange potential of the synthesized
samples for Sr2+ and Cs+ and effective parameters such as concentration, temperature, time, and pH were investigated. In addition,137Cs and 90Sr radio nuclides absorption in the best appropriate sample was examined. The selectivity of the samples for absorption of
137Cs and 90Sr was studied by gamma spectroscopy, liquid scintillation spectrometry, and atomic absorption spectroscopy methods. The obtained
results showed that the prepared samples had good potential for absorption of 137Cs and 90Sr from the model solution. The sample containing equal amount of niobium and germanium, removed completely the 137Cs within the waste water of Tehran nuclear reactor and 90Sr in the desired solution.

Applying different institutional addresses in the scientific production of a same university has underestimated the scientific
production of Iranian universities and consequently lowered their position in the international academic rankings for a long
time. The present study evaluated the scientific production of Iranian medical universities according to their institutional
addresses registered in the papers indexed by Science Citation Index Expanded (SCIE). By conducting a descriptive research
we retrieved total SCIE indexed of top Iranian medical universities and their respective hospitals and research centers from
the beginning of 1986 to the end of 2007. Then different variations of the institutional addresses of each university in the
author affiliation of papers were assessed. Finally the universities were ranked according to observing a uniformed format
for more registered addresses in SCIE. The findings showed unexpected diversity in the institutional affiliation of each university
in their SCIE indexed papers. Although “Tehran University of Medical Sciences” showed the most variation in registering institutional
addresses but ranked first according to observing unification for more addresses in the SCIE indexed papers comparing to the
other universities. The problem of applying different institutional affiliations in the scientific production of the universities
should be valued enough by the whole scientific community. Observing a uniformed format in registering institutional addresses
of Iranian medical universities would affect their scientific credibility and international ranks through representing their
real scientific productivity.
198Au (βmax = 0.96 MeV (98.6 %), γmax = 0.412 MeV (95.5 %) and T1/2 = 2.7 days) is a radionuclide with very appealing characteristics. 198Au has been widely used to treat the uterus, bladder, cervix, prostate, melanoma, breast, skin and other cancers. In the present
study, cationic 198Au+3 and nonionic 198Au0 are prepared following thermal neutron irradiation of commercially available natural gold compounds in Tehran Research Reactor
via the natAu(n,γ)198Au reaction. The prospects in the production of pure 198Au0 and 198Au+3 for radionuclide therapy are discussed and effect of reduction on the activity of radioactive gold is evaluated. Au0 particles were synthesized via NaBH4 reduction of aqueous solutions of hydrogen tetrachloroaurate trihydrate. Then two quartz tubes were charged with cationic
198Au3+ and nonionic 198Au0. After irradiation by thermal neutrons, the samples were analyzed for a period of 1 month by liquid scintillation counter
and high purity germanium detector. As a result, natAu3+ reduction process had no significant effect on the activity of the 198Au sample. In conclusions, natural gold thermal neutron activation cross section is reasonably high for medical application.

Introduction There are many researches have been conducted on webometrics, especially the impacts of websites on each other and the web
impact factor. However, there are few studies focusing on the websites of Iranian universities. This study analyzed the websites
of Iranian universities of medical sciences according to the webometric indicators.
Method and materials In a cross-sectional study, the number of web pages, inlinks, external inlinks and also the overall and absolute web impact
factors for Iranian universities of medical sciences with active exclusive websites were calculated and compared using AltaVista
search engine. Finally, the websites were ranked based on these webometric indicators.
Results The results showed that the website of Tehran university of medical sciences with 49,300 web pages and 9860 inlinks was ranked
first for the size and number of inlinks, while its impact factor was ranked 38th. Rafsanjan UMS with 15 web pages and 211
links had the highest rank for the web impact factor among Iranian universities of medical sciences.
Discussions and conclusions The study revealed that Iranian universities of medical sciences did not have much impact on the web and were not well known
internationally. The major reason relies on linguistic barriers. Some of them also suffer from technical problems in their

This study investigates the effect of explicit vs. implicit prosody teaching on the quality of consecutive interpretation by Farsi–English interpreter trainees. Three groups of student interpreters were formed. All were native speakers of Farsi who studied English translation and interpreting at the BA level at the University of Applied Sciences, Tehran, Iran. Participants were assigned to groups at random, but with equal division between genders (6 female and 6 male students in each group). No significant differences in English language skills (TOEFL scores) could be established between the groups. Participants took a pretest of consecutive interpreting before starting the program. The control group listened to authentic audio tracks and did exercises in consecutive interpreting. The first experimental group received explicit instruction of English prosody and did exercises based on the theoretical explanation which was provided by their Iranian instructor. The second experimental group received implicit instruction of English prosody through the use of recasts. The total instruction time was the same for all the groups, i.e. 10 hours. Students then took a posttest in consecutive interpretation. The results showed that explicit teaching of prosody had a significantly positive effect on the overall quality of interpreting from Farsi into English compared with that of implicit prosody instruction. These results have pedagogical implications for curriculum designers, interpreter training programs, material producers and all who are involved in language study and pedagogy.

To evaluate the genetic background of quantitative criteria of drought tolerance in wheat, six generations of a cross between the varieties of Plainsman and Cappelle Desprez were grown in a randomized complete block design with three replications in the greenhouse of the College of Agriculture of the University of Tehran in 1997. Genetic variation was found for yield potential (Yp), stressed yield (Ys), excised leaf water retention (ELWR), relative water loss (RWL), relative water content (RWC) and harvest index (HI) under water stress conditions. High heterosis and heterobeltiosis were observed in the F1 hybrid for Ys, HI and spike yield index (SYI). Genetic analysis exhibited overdominance in the inheritance of Ys, RWL, ELWR, HI, biomass and SYI, while RWC and Yp were controlled by the additive type of gene action. High narrow-sense heritability estimates were shown by ELWR, biomass and SYI. The high genetic advance for ELWR, RWC, HI and SYI indicated that direct selection could be effective for these traits. The epistatic effects (additive × additive=[i] for Yp, Ys and RWL, additive × dominance=[j] for ELWR, and dominance × dominance =[l] for RWL) were found to be outstanding.
