the tabriz fault in northwest of iran is the important geological structure in our country which historical earthquakes were recorded around it. the purpose of this paper is the study of tabriz fault seismotectonic activity. the method of research is drawing 23 cross section vertical to tabriz fault between tabriz and bostan-abad distinguish mountain-front faceting, mountain-front sinuosity and...

Valley fever (VF) is difficult to diagnose, partly because the symptoms of VF are confounded with those of other community-acquired pneumonias. Confirmatory diagnostics detect IgM and IgG antibodies against coccidioidal antigens via immunodiffusion (ID). The false-negative rate can be as high as 50% to 70%, with 5% of symptomatic patients never showing detectable antibody levels. In this study,...

In this paper, we apply an effective method to evaluate relative tectonic activity by applying several morph-tectonic indices that are useful in evaluating topography and tectonics. These include stream length-gradient, asymmetric factor, hypsometric index, curves, valley floor width height ratio, drainage basin shape, mountain front sinuosity. The study region of Wadi Al-Arish northern Sinai P...

Like many montane rivers in the western U. S., the Middle Fork of the John Day River is characterized by alternating narrowand wide-valley segments. Although the river has a low gradient (generally < 0.01) alluvial channel, changes in valley width exert a clear infl uence on channel morphology. A spatial hierarchical model of channel morphology was applied to the Middle Fork to understand reach...

rijab valley, located in 180 km west of kermanshah, is considered to be one of the tourists centers of kermanshah because of having various landscapes and monuments. however, the results of one of the field studies of 157 tourist subjects show that the majority of the tourists do not know much about all the attractions of the valley. in a way that about 31.2% of the tourists were not aware of t...

The valley oak (Quercus lobata Neé) is among the largest and longest lived of the North American oaks, attaining trunk diameters up to 4 m, heights of 12 to 25 m, and ages of 300 years or more. Unique to California, this oak is also one of California’s most familiar and evocative icons. Where they occur, large valley oaks are focal visual and ecological elements of both developed and rural land...
