In the current study, we conducted a mutation screening of tumor-associated calcium signal transducer 2 (TACSTD2) gene in six consanguineous Iranian families with gelatinous drop-like corneal dystrophy (GDLD), in order to find the causative mutations. Detailed eye examination was performed by ophthalmologist to confirm GDLD in patients. To detect the possible mutations, direct Sanger sequencing...
بررسی قابلیت پارامترهای ژئومرفومتری در تفکیک مخروطافکنههای مناطق بیابانی (مطالعۀ موردی: عقدا، یزد)
This research focuses on alluvial fans in desert area. Alluvial fans are one of the most important geomorphological units in desert area. There are several tremendous methods to separate alluvial fans. There are qualitative and quantitative factors to differentiate them from other geomorphological units. In this study effective geomorphometrical parameters in differentiate landforms were applie...
Dust emission and sand mobilization are the common natural hazards in desert roads of Iran, which originate from geomorphological facies of road margin. In this study, the geomorphological units of Yazd-Meybod road margin were distinguished, and the samples were taken from these facies as origin area while roads sediment as the transition area of sediments. The samples were analyzed using morph...
The South Saskatchewan River has a long term average discharge of 275 m3/sec, with flood peaks in the range of IS00 to 3800 nP/sec. South of Saskatoon, the four major types of geomorphological elements recognised are channels, slipfacebounded bars, sand flats and vegefated islands and floodplains. Major channels are 3-5 m deep, up to 200 m wide, and flow around sand flats which are 50-2000 m lo...
abstract the purpose of this paper is to inform students and researchers of geomorphology from the situation of this science at present and in future, in iran, after the islamic revolution. to fulfill this purpose and to prouide full information about the situation of geomorphology in iran, various areas of this science are presented chronologically at the begining of the article. the findings ...
Kaloutaks are a geomorphological forms of arid and semi-arid regions around the world. These features are extensive and varied in Iran, resulting from the erosion of fluvial and lake sediments of the Quaternary. Kaloutaks are mostly extended over the Eastern and Southeastern Iran and have unique features. Meanwhile, the kaloutaks in the playa of Sistan Hamun are considerably extended. The stud...
Fruits exhibit a vast array of different 3D shapes, from simple spheres and cylinders to more complex curved forms; however, the mechanism by which growth is oriented and coordinated to generate this diversity of forms is unclear. Here, we compare the growth patterns and orientations for two very different fruit shapes in the Brassicaceae: the heart-shaped Capsella rubella silicle and the near-...
This paper presents Celtic Canvas -a framework towards computationally generating patterns similar to simple Celtic artwork. As Celtic patterns are highly structured, a robust model of curvature dynamics is introduced in the paper to allow the evolution of space curves as a foundation for line drawing and structural anatomy. Cellular automata integrates several features including -lines and for...
We present a geologically-based method to generate complex karstic networks. Karsts are type of landscape formed by the dissolution highly soluble rocks (generally limestones). In particular, they characterized underground networks made varieties tunnels and breakout chambers with stalagmites stalactites. Our computes skeletons using gridless anisotropic shortest path algorithm according field ...
Identification of the remnant traces paleo-glaciers provides important proxies to understand response environment rapid climate changes. We present a 1:25,000 scale geomorphological map covering ∼12.5 km2 upper part Mount Bistra (North Macedonia) on basis remote sensing analyses and surveys. Particular attention is given description glacial periglacial landforms, reconstruction single glacier s...
