این تحقیق با هدف ارزیابی قابلیت مدل شبکه عصبی مصنوعی در تهیه نقشه پیشبینی پراکنش رویشگاه گونههای گیاهی و شناخت نقاط قوت و ضعف این روش انجام شد. بدینمنظور بعد از تعیین واحدهای همگن با استفاده از مدل رقومی ارتفاع و نقشه زمینشناسی با مقیاس 1:25000، نمونهبرداری از پوشش گیاهی و عوامل محیطی انجام گرفت و نقشه مربوط به متغیرهای محیطی با استفاده از سیستم اطلاعات جغرافیایی و زمین آمار تهیه شد. مت...
artemisia deserti krasch (a. deserti), artemisia aucheri (a. aucheri) and artemisia sieberi besser (a. sieberi) are three members of asteraceae (compositae) family, which grow widely in the even and high areas of birjand, iran. this study has attempted to compare the total antioxidant capacity of methanol extracts of these three plants using dpph (1,1-diphenyl-2-picrylhydrazyl) radical scavengi...
epizoochory and endozoochory are well-known mechanisms by which seeds are dispersed by animals. since, livestock gather around the watering-points to rest and drink, we expected to find that seeds would be frequently moved to the areas surrounding watering-points, resulting a higher soil seed density (and diversity) closest to the water. we investigated this issue by assessing soil seed bank de...
most serious problem that leads to reproductive system failure in both human and animals. Present study was carried out to investigate whether hydroalcholic extract of Dorema aucheri leaves could protect the male rats against lead-induced reproductive toxicity. Materials and Methods: Adult wistar rats were treated with 0.1% lead acetate in drinking water with or without 100, 200 and 400 mg/kg D...
background artemisia aerial parts are well known for antimicrobial activities including anti malaria. objectives this study was carried out to evaluate the antimicrobial activity and chemical composition of essential oil from the seeds of artemisia aucheri boiss (asteraceae). materials and methods essential oil was extracted from the powdered seeds of artemisia aucheri by hydrodistillation. ant...
در این پژوهش، شباهتها و تفاوتهای آناتومی چوبِ چهار گونۀ درختچه ای از منطقۀ سراب استان آذربایجان شرقی برای درک بهتر تطبیق پذیری بافت چوبی با اقلیم خشکِ منطقه بررسی شد. این درختچهها عبارتاند از: پرند (Pteropyrum olivieri)، نسترن کوهی (Rosa canina)، ارجنگ (Rhamnus pallasii)، و گز انگبین (Tamarix gallica L) که آناتومی چوب یکی از آنها (سَردۀ Pteropyrum) برای نخستین بار است که در جهان گزارش می...
M. sylvestris inhibits C. albicans biofilm formation Journal of Herbmed Pharmacology, Volume 6, Number 2, April 2017 http://www.herbmedpharmacol.com 63 increased expression of drug efflux pump genes and metabolic plasticity provide protection by preventing the penetration of host immune factors and antifungals agents into the extracellular matrix in comparison to planktonic cells (3,6-10). The ...
treatment of soils contaminated with heavy metals using plant species is a method which has been widely used in thepast. this method, which is known as phytoremediation, has been applied for pollution treatment using different plantspecies worldwide. the method has been used for remediation of various types of pollutants in laboratory, pilot andindustrial scales. the aim of this study was to co...
