The main objective of this study is estimating acceleration time history of 16 September 1978 Tabas earthquake incorporating the seismological/geological source-path and site model parameters by using finite-fault simulation approach. The method generalizes the stochastic ground-motion simulation technique, developed for point sources, to the case of finite faults. It subdivides the fault plane...

the nayband formation was measured and sampled in parvadeh area, southern tabas city. in this area, this formation has a thickness of 1410 m, dividing into four members, namely gelkan, bidestan, howz-e-sheikh and howz-e-khan. a total 573 samples were treated for palynological analysis, and only 120 samples were productive. a total of 57 miospore taxa and 11 plant macrofossil were encountered. b...

this study was conducted to estimating the amount of non-standard sizes (with lengths less than lm50) fishes of shrimp trawls in the hormozgan province coastal water during shrimp fishing season. sampling was carried out using the tabas otriger commercial trawler during 55 hauls. eight commercially valuable species including pampus argenteus, parastromateus niger, plicofollis dussumieri, saurid...

family muridae consists of eight genera and 28 species in iran. this family shows notable variability of karyological features. in this study, karyological data derived from 11 species of 7 genera of this family of iran are presented and compared with previously published accounts. the included species were: mus musculus musculus from gonbad (2n=40, fn=40) and birjand (2n=40, fn=38), rattus nor...

The transcription factor Sp1 has been implicated in regulation of the expression of the murine CTP:phosphocholine cytidylyltransferase alpha (CTalpha) gene, Ctpct (M. Bakovic, K. Waite, W. Tang, I. Tabas, and D. E. Vance. 1999. Biochim. Biophys. Acta. 1438: 147;-165). We have utilized transient transfections, mutation analysis, electromobility gel-shifts, and immunoblot analysis to test the hyp...

CTP:phosphocholine cytidylyltransferase (CCT) is the rate-limiting and regulated enzyme of mammalian phosphatidylcholine biosynthesis. There are three isoforms, CCTalpha, CCTbeta1, and CCTbeta2. The mouse CCTalpha gene promoter is regulated by an enhancer element (Eb) located between -103 and -82 base pairs (5'-GTTTTCAGGAATGCGGAGGTGG-3') upstream from the transcriptional start site (Bakovic, M....

in this paper, seismic behavior of the existing buildings equipped by friction dampers is studied. seismic performance of6-story, 9-story and 12-story steel buildings with damper and without damper were studied. the finite element modeling technique (sap2000 software) is used for analysis. time history analyzing was done to achieve this purpose. for nonlinear dynamic analysis, the responses of ...

Abstract Tri-flo cyclone, as a dense-medium separation device, is one of the most typical environmentally friendly industrial techniques in coal washery plants. Surprisingly, no detailed investigation has been conducted to explore effectiveness tri-flo cyclone operating parameters on their representative metallurgical responses (yield and recovery). To fill this gap, work for first time process...
