Mitochondria1 DNA (mtDNA) control region sequences were analyzed to evaluate the population genetic structure of Persian sturgeon (Acipenser persicus) in Caspian Sea. A total of 45 specimens were collected from the different locations of the Caspian Sea. MtDNA control region was amplified using PCR. Direct sequencing was performed according standard method. The results showed that 12 haplotypes...
The collision of India with Asia, one of the most profound tectonic events to have occurred in past 100 m.y., is thought to have had geological, geochemical, and climatological consequences of global extent. Surprisingly the age of initiation of this collision remains poorly constrained. Estimates range from the Late Cretaceous (.65 Ma) to latest Eocene (,40 Ma), with little consensus in betwee...
-. This roper discusses in *M tie process undetien to mitigate the effects of any fiture mine subsidence on prison structures proposed above old abandoned underground workings. The site for a proposed prison complex purchased by the State of Indiana was located in west-central Indiana and was undermined by an old abandoned room and pillar mine. The original plan for construcdon cmsisted of one ...
Genetic structure of Acipenser persicus, in the Caspian Sea was studied using tetrasomic microsatellite markers. A total of 195 specimens of A. persicus breeders were collected from the sampling stations located in the five fishery catch zones as well as from the Sefidrud River in the south Caspian region. About 2 g of caudal fin samples was collected from each sturgeon specimen and preserved i...
The genus Alburnoides Jeitteles, 1861 in Iran is reviewed, and diagnoses are presented for all eight recognized species. Alburnoides eichwaldii, A. holciki, A. idignensis, A. namaki, A. nicolausi, A. petrubanarescui, A. qanati and A. tabarestanensis are considered valid and three new species are described: Alburnoides coadi sp. n., from Namrud River in Kavir basin, A. parhami sp. n., from Atrak...

Land subsidence is one of the environmental hazards that has been less well-regarded by human societies due to lower human casualties. However, the earth subsidence causes irreparable damage to the urban areas and adjacent plains over time. In this study, Permanent Scatterer (PS) method has been used to monitor land subsidence in the region in hamadan proviance and its adjacent plains in west o...
language learning courseware has been receiving growing attention by english educators since its advent. a variety of softwares have been designed by software designers and resorted to by language educators to supplement language textbooks. this experimental study investigated how the application of computerized version of language textbooks and the reception of the entire course through comput...
Background and objective: The land subsidence is commonly associated with many risks. This phenomenon can cause substructure and natural damages, and ultimately leads to an increased risk in society and the economy. The most studies are focused on modeling and its techniques, except for two case studies in Tehran: the risk of subsidence phenomenon and the elements exposed to this risk which has...
using global free air gravity and topography data, first we have calculated a bouguer anomaly (ba) map for iranian plateau and then computed the residual isostasy anomaly map under the airy-heiskannen assumption. the term residual is used as to reflect the assumption of local isostatic compensation in contrast to a regional isostatic compensation. the value with which the gravity effect of the ...
