abstract water retention curve (wrc) is a fundamental property of soil. it is used to evaluate available water, permeability, drainage and movement of solutes. despite numerous studies on wrc of soils abroad, no local study has been carried out on charmahal-va-bakhtiari soils. the objective of this study was to compare the quality of fitting of several wrc models to lordegan soils and to select...
an earthquake was happened on 23 october 2011 in van, turkey (mw7.2) at the eastern most area of anatolian plateau and in the neighborhood of iranian border (west azerbaijan province). the study was performed based on field and office observations and has been focused on the process of disaster management in turkey after the 23 october 2011 earthquake. we surveyed the quake from the view point ...
We investigate a monetary regime with persistent, near-zero policy interest rates (“permazero”). This regime was implemented in 1683 by a prominent early central bank, the Bank of Amsterdam (“Bank”). Under this regime, the Bank’s policy rate remained at one-half percent for over a century. We employ archival data to reconstruct the Bank’s activities over a subsample of this regime (1736-1791) f...
یک روش تکثیر درون شیشه¬ای کارآمد به منظور تکثیر گونه rosa hybrid واریته city of leads از طریق تکثیر جوانه جانبی بررسی گردید. در ابتدا ریزنمونه¬ها به منظور استقرار بر روی دو محیط کشت ms و van der salm در ترکیب با غلظت¬های مختلف هورمون¬های ba و naa کشت گردیدند. بیشترین درصد استقرار ریزنمونه¬ها (100 درصد) و تعداد نوساقه¬ها (4/3 نوساقه در هر ریزنمونه) در محیط van der salm حاوی 2 میلی¬گرم در لیتر ba...
Direct measurement of soil unsaturated hydraulic conductivity (K(h) or K(θ)) is difficult and time-consuming, and often in many applied models, predicting hydraulic conductivity is carried out according to measurements of soil retention curve and saturated hydraulic conductivity (Ks). However, using KS as a matching point in many procedures may result in over-estimation of unsaturated hydraulic...
chondroectodermal dysplasia (ellis-van creveld syndrome) is a rare autosomal recessive congenital abnormality. this syndrome is characterized by a spectrum of clinical findings, among which chondrodystrophy, polydactyly, ectodermal dysplasia, and congenital cardiac anomalies are the most common. it is imperative to not overlook the cardiac complications in patients with this syndrome during den...
مقدمه: بسیاری از افرادی که در جنگ حضور داشتهاند ،جانبازی را تجربه کرده اند .تجربه منحصر به فرد جانبازان در مطالعات معدودی مورد بررسی قرار گرفته است .هدف این مطالعه فهم تجربه جانبازان است که موجب شناخت و توصیف تجارب جانبازان و کسب بینش عمیق از این پدیده میباشد. روش: این مطالعه کیفی به روش پدیدارشناسی در سال 1393 به اجرا درآمده است. شیوه گردآوری دادهها، مصاحبه های نیمه ساختار یافته بوده که ...
