the study area, paykola anticline, is located in the southwestern part of kermanshah province. the aim of this research is to evaluate the geomorphological indexes of active tectonics in paykola anticline as well as to study the effect of tectonic in the form and direction of geomorphological landforms. to achieve the aim of study, the lithological and tectonic characteristics of study area wer...

We establish fluorescence fluctuation spectroscopy (FFS) with nanoscale detection volumes generated by stimulated emission depletion. Our method applies fluorescence correlation spectroscopy and fluorescence intensity distribution analysis to extract molecular information about mobilities and fluorescence emission in solution. The combination of correlation analysis with that of photon intensit...

PURPOSE To investigate the underestimation of field loss in functional field score (FFS) between the Goldmann isopters III-4e and V-4e in visually impaired patients, in order to develop a predictive model for the FFS(III-4e) based on FFS(v-4e) that adjusts for possible confounders. Although the visual field is generally evaluated using Goldmann isopter III-4e, it has the disadvantage that not a...

The Lower Khazir River provides a good example of changes in river alignment associated with neotectonic movements. The aim of this paper is to address the two following questions: 1How big an impact does the river exert upon the process of (fold) anticline growth? 2Where are the largest geomorphic changes along the lower course of the Khazir River and how are they connected to the sinuosity of...

Tectonic processes are major factors controlling landform development in tectonically active areas. In order to evaluate quantitative measurement of tectonic activities in the Alamarvdasht basin in the south of Iran, six different morphological indices including stream-gradient index (SL), drainage basin asymmetry (Af), hypsometric integral (Hi), valley floor width-valley height ratio (Vf), dra...

The Khushab anticline is located in the Zagros fold-thrust belt in the Lurestan. This anticline is affected by the Balarud fault zone, which is a part of Mountain Front Fault between the Lurestan and Dezful Embayment zones. Based on the measurement of the elements of fold style, this anticline is analyzed. According to these measurements, this anticline is a noncylindrical, asymmetrical and dis...

We develop a new method for analysis of meandering channels based on planform sinuosity. This analysis objectively identifies three channel reach lengths based on sinuosity measured at those lengths: the length of typical, simple bends; the length of long, often compound bends; and the length of several bends in sequence that often evolve from compound bends to form multi-bend loops. These leng...

The swimming behaviour of ten species of diving beetles was studied with a video image analysing system, with the aim of testing the interpretation of their size and shape as functional characters reflecting adaptations to different swimming strategies. Velocity, sinuosity of the trajectory, and the relation between the two were studied in an unobstructed aquarium and, for the four largest spec...
