1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
the alborz mountains, as a folded and faulting region, is the northern region of crust shortening in iran. dominant mechanism (harvard, 2002) of alborz earthquakes is left-lateral strick-slip paralleled to the range. east alborz is one of the active regions that plays a significant role in the tectonics of its neighbors like south casbin basin. regarding the geological maps of the area, the fau...
Recently, concerning failure of structures due to earthquakes, special investigations of near fault ground motions have been noticed. Hence, in this paper, characteristics of near field ground motions have been considered in horizontal and vertical directions. In this consideration, the record averages have been compared with Uniform Building Code and Eurocode8 spectra in two levels. In additio...
Abstract The tectonic stress field was investigated in and around the aftershock area of Hokkaido Eastern Iburi earthquake ( M JMA = 6.7) occurred on 6 September 2018. We deployed 26 temporary seismic stations for approximately 2 months located 1785 aftershocks precisely. Among these aftershocks, 894 focal mechanism solutions were determined using first-motion polarity P wave from observation p...
In this study, an inversion method is conducted to determine the focal mechanism of Sefid-Sang fault by comparing interferometric synthetic aperture radar (InSAR) technique and dislocation model of earthquake deformation. To do so, the Sentinel-1A acquisitions covering the fault and its surrounding area are processed to derive the map of line of sight (LOS) displacement over the study area. The...
reflection and refraction of em signals at both horizontal and vertical interfaces separate media of different electrical parameters, geoelectromagnetic methods have been developed and employed to recognize the geological features and particularly fault zones in many regions. to achieve higher lateral resolution and also greater depth penetration, the mt method is one of the most effective elec...
background and aim: the video head-impulse test (vhit) measures the vestibulo-ocular reflex (vor) driven by each semicircular canal, following high-acceleration head rotations. the main measurable response is the ratio of eye movement velocity to the angular head velocity, which reflects canal function. although normative data is available for vor gain, most studies only report horizontal vo...
The excavation in the Wanfung area has provided evidence for at least three earthquake ruptures, including the 1999 ChiChi one. The Chi-Chi earthquake formed an obviously major reverse fault, backthrust, and several minor normal faults, accompanied by a teardrop-shape anticline in the fault tip. Paleoseismic ruptures I and II show the vertical displacement of 0.4 m and 1.2 m, respectively, whic...
in the last 150 year, most destructive earthquakes of kopeh dagh occurred near quchan. these earthquakes caused large damages to quchan (tchalenko, 1975; ambraseys and melville, 1982). the kopeh dagh zone accommodates a motion, by a combination of slip-partitioning in the nw, thrust faulting in the se, and anticlockwise block rotation in the central kopeh dagh (hollingsworth et al. 2006, 2008)....
