Background and objectives: Hippophae rhamnoides L. known as sea buckthorn is a deciduous medicinal shrub belonging to Elaeagnaceae family. In this study, the most important chemical constituents of sea buckthornwere evaluated in wild populations of central Alborz Mountains in Iran during the growth season of 2014 and 2015. Methods: Phy...
The Iranian Plateau is characterized by diverse tectonic domains, including the continental collisions (e.g. the Zagros and Alborz Mountains) and oceanic plate subduction (e.g. Makransubduction zone). To derive a detailed image of the crust–mantle (Moho) and lithosphere–asthenosphere (LAB) boundaries in some tectonically units of the Iranian Plateau, we used a large number of S receiver functio...
Basalts in the Gasht-Masuleh area crop out in the SW Fuman, Gilan Province, and are exposed in the Jurassic and Late Cretaceous units in this area. Whole rock chemistry shows that the rock samples have Mg numbers between 30 and 31.7. Rare earth element patterns (REE) indicate light REE (LREE) enrichment and heavy REE (HREE) depletion (LaN/YbN= 7.7-9.8). Nb, Ta and Ti negative anomalies in primi...
The Middle East contains a great diversity of Capoeta species, but their taxonomy remains poorly described. We used mitochondrial history to examine diversity of the algae-scraping cyprinid Capoeta in Iran, applying the species-delimiting approaches General Mixed Yule-Coalescent (GMYC) and Poisson Tree Process (PTP) as well as haplotype network analyses. Using the BEAST program, we also examine...
Achillea millefolium L. is one of the most famous medicinal herbs that has been used extensively in ancient medicine for the treatment of diseases in general and wounds and burns in particular. This plant has many subspecies that different compounds of monoterpene and sesquiterpene are found in its essential oil. The purpose of this study was to analyze and compare the yields and essential oil ...
the iranian plateau is characterized by diverse tectonic domains, including the continental collisions (e.g. the zagros and alborz mountains) and oceanic plate subduction (e.g. makransubduction zone). to derive a detailed image of the crust–mantle (moho) and lithosphere–asthenosphere (lab) boundaries in some tectonically units of the iranian plateau, we used a large number of s receiver functio...
BACKGROUND The reservoir and intermediate hosts of Echinococcus granulsus and human hydatidosis are more prevalent in the Alborz and Zagros Mountains slop due to rich pastures for sheep raising. Many cases of hydatid cysts operate in local hospitals annually. The present study aimed to review the epidemiologic characteristics of the hydatidosis patients. METHODS In this descriptive study, the...
Twenty taxa of Lower Givetian rugose corals have been investigated in the Dreimühlen Formation from Meerbüsch quarry, Eifel Hills. The fauna consists mostly solitary coralla associated with some fasciculate specimens Disphyllum caespitosum (Goldfuss, 1826) and large massive colonies Argutastrea briceae (Rohart, 1988). genus Marennophyllum n. gen. is introduced Cystiphylloides marennense Coen-Au...
Article history: Received June 26, 2012 Received in Revised form August, 12, 2012 Accepted 15 September 2012 Available online September 17 2012 One of the primary concerns with data envelopment analysis arises when the number of inputs and outputs increases. In such a case, required computations will become time consuming and there is a concern on developing some hybrid methods to increase the ...
