the effect of environmental factors on plant vegetation is different. therefore, it is necessary to evaluate role of these factors in medicinal plants growth, development and essential oil. this study was performed to investigate the effect of factors on qualitative and quantitative variations of the essential oil of verbascum songaricum in its habitats in central zagros mountains, iran in 2012...

this contribution determines suitable fingerprinting properties for sediment source discrimination within theamrovan and atary catchments in semnan province, iran. these catchments are representative of a range of geology formations and should therefore provide a meaningful basis for a general assessment of the degree of sediment source discrimination afforded by a range of fingerprint properti...

Annually, 200 ha of Agh Ghala rangelands in Golestan, Iran are under Alkaligrass Puccinella distans's cultivation but the failure in the identification of appropriate sites for seed sowing may result in high costs of cultivation. The current study aims to reduce such costs through the examination of apt sites to grow P. distans in northern rangelands of Agh Ghala Golestan, Iran. Because of the ...

The cytological features including chromosome numbers and detailed measurements of 46 populations ten Achillea species ( A. aleppica, bibersteinii, eriophora, filipendula, millefolium, nobilis, pachycephala, tenuifolia, vermicularis, wilhelmsii ) were reported from Iran. Sample plants seeds collected diff erent geographical regions Total length, long/ short arm ratio, centromere index, total fo...

M. Dudek, AGH University of Science and Technology, Krakow, Faculty of Management, Poland In the blast-furnace production, raw materials may account for approx. 50 % of the pig-iron manufacture costs. Therefore, any, even small, saving in the sphere of raw material purchasing will translate into the reduction in the cost of the pig-iron manufacture. The selection of appropriate supply sources a...

Ultraviolet photodissociation (UVPD) mass spectrometry is employed to investigate the structure of holo-myoglobin as well as its apo form transferred to the gas phase by native electrospray. UVPD provided insight into the stability of native structural elements of holo-myoglobin. The fragmentation yields from UVPD showed the greatest overall correlation with B-factors generated from the crystal...
