“…In terms structural geology zones, there have been too many tectonic disasters in variate geology areas and in terms active tectonic indexes such as drainage basin shape [3], mountain front sinuosity (Smf), ratio of valley-floor width to valley height(Vf), stream length-gradient [4], hypsometric integral (Hi) and drainage basin asymmetry (Af) is active and variation. Because one of the best methods to study and evaluate of active tectonic is, to determine the land form of geometry or morpheme-try factors.…”

“…Slide zones under title erosion types are related to more active tectonic factors. For example drainage basin shape [3], mountain front sinuosity (Smf), the ratio of valley-floor width to valley height (Vf), stream length-gradient [4], hypsometric integral (Hi) and drainage basin asymmetry (Af).…”

“…In terms of seismotectonic and its mechanism, it is also dependent on the general seismotectonic of the mentioned zone [this zone comprises about 10.43 percents of the earthquakes in Iran] and has abundant earthquakes but mainly with magnitude 4 to 5.5 at Richter scale and with low focal depth (earthquakes with focal depth lower than 50 km) [10]. As a result, the issue of active tectonics is notable in the region and most indices of active tectonics such as drainage basin shape [3], mountain front sinuosity (Smf), ratio of valley-floor width to valley height (Vf), stream length-gradient [4], hypsometric integral (Hi) and drainage basin asymmetry (Af) are presented in study region.…”

This research shows a noticeable comparison between slide zones produced with the results using the Nilsen method with active tectonic hazard zonation map. A determination landform of geometry or morphometry factors is one of the best methods for study and evaluation active tectonics. The first image provided is a Dem maps from GIS software showing topography, geology and tectonic maps participant with field activities. The second image provided shows an active tectonic map also generated by the same above mentioned factors into three classes A, B, C, D and a landslide hazard zonation map which shows five classes: Stable zone, generally stable zone, stable moderately stable zone, moderately stable zone and talented to liquefaction zone. The study and comparison and conformity landslide hazard zonation map with hazard zonations into active tectonic hazard zonation map showed about 79 percent (56,880 hectare) moderately unstable zone and talented for liquefaction zone settled in A zone (very high tectonic activity) and B zone (high tectonic activity) active tectonic map and 21 percent (15,130 hectare) remain unsettled sequential 12 percent (8640 hectare) and 9 percent (6480 hectare) in C (moderate tectonic activity), D (lowest tectonic activity) zone of active tectonic hazard zonation produced from above mentioned factors. This research showed a relationship between slide zones produced in landslide hazard zonations using the Nilsen method to measure active tectonic hazard zonation in the study region.

“…We have been successfully used this method for measurement of 0 of a CW CO 2 laser earlier (Aram, Soltanmoradi, Ghafori, & Behjat, 2005). To our knowledge, only one report is available on a rare gas Halide pulsed laser based on using an intra-cavity variable absorption gas cell loss element (Armandillo, Kearsley, & Webb, 2000). The 0 and can be measured at the line center of a single-longitudinal-mode laser, the result of measurements being dependent on the broadening.…”

The small-signal gain coefficient of a TEA CO 2 laser has been measured through the implementation of a variable polarization intra-cavity loss element. Charging voltage dependence of the gain property of the laser has been investigated. The advantage of this method is that no probe laser system is required. The results have been agreed with experimental data obtained by conventional oscillator-amplifier method.

“…An NO2 gas absorption cell was used to attenuate the KrF beam, at various stages of the experiments described in this thesis. The use of such a cell (as a method for measuring the gain of rare-gas halide lasers) was first proposed by Armandillo et al [1982]. By varying the pressure of gas in the cell, it was possible to vary the attenuation provided.…”

Short wavelength lasers and their applications Adam Whybrew, Jesus College A thesis submitted for the degree of Doctor of PhilosophyOxford University Trinity Term 1996 I owe a great deal to the people listed below, and it is not possible to do justice to them here. It is a genuine pleasure to thank:Colin Webb, my supervisor, for never failing to make time to help me, with his real wealth of experience and ingenuity.Tony Andrews, for always being available to give me vital lessons in laser building, electronics, optics, and plumbing, as well as rescuing my pot plants from an arid doom.Julian Fletcher, my predecessor, for teaching me how to use the laser he made, and then how to repair it. David Coutts, forshowing me what a post-doc is for. His often unsolicited but invariably welcome day-to-day interest in what I was doing was a real boon.Constantin Cristescu, for his enthusiasm and charm, and for his perspiring jobs.Deborah Swarts, for dropping an electrode, leading to the KrF laser becoming a worldbeater.George Matthews, for patiently teaching me everything I know about making things, and saving me from injury as necessary.Chris Goodwin for making optical coatings and lending me a spin-coating kit.
