چکیده: قارچ های میکوریز آربوسکولار (am) از دیرباز به عنوان همزیست ریشه گیاهان در بهبود رشد آنها در شرایط فقر غذایی و تنش های محیطی، موثر شناخته شده است. علی رغم فواید بیشمار این همزیستی، تکثیر انبوه این قارچ ها به دلیل ماهیت اجباری این همزیستی، تاکنون در محیط های مصنوعی امکان پذیر نبوده و صرفاً در حضور ریشه زنده تکثیر می یابند. شواهدی وجود دارد که حضور برخی میکروارگانیسم ها از جمله اکتینومیست ه...
Nutall's algorithm for the computation of PN(x) = E^o prx at xn = x0 + n\, n = 0, 1, 2, • • • requires converting PN(xn) to QN(n) ±?. N m = aann . Recursion is then carried out through Qk + , (n) = Qk + , (n 1) + gj(n), * = 0, 1, • • • , N 1. This requires the initial values fiv_r(0), r = 0, 1, 2, • • • , N. We present here explicit and easily programmable formulas for am as well as Q,v-r(0), i...
Corresponding Author: Manabu Tobisa Faculty of Agriculture, University of Miyazaki, Miyazaki, 889-2192 Japan Email: [email protected] Abstract: This study examined the growth and Arbuscular Mycorrhizal (AM) colonization of two tropical forage legumes, namely, American jointvetch (Aj) and Greenleaf desmodium (Gd), at two phosphate application rates (0 or 10 g P m −2 yr −1 ; -P or +P), ...
We examined the effects of the vasodilator peptide adrenomedullin (AM) infused intravenously into subjects with essential hypertension. Eight men 39 to 58 years old with uncomplicated hypertension (147/96+/-5/3 mm Hg at baseline) were studied in a placebo-controlled, crossover design. Each subject received intravenous AM in a low and a high dose (2.9 and 5.8 pmol. kg(-1). min(-1) for 2 hours ea...
Objective- This study was performed to evaluate and compare grossly and pathologically two surgical techniques of amniotic membrane patching on experimental corneal alkali burn in dogs. Design- Experimental study. Animals- Fifteen healthy dogs Procedures- The central corneas of the dogs were inflicted by applying a round filter paper, 6.0 mm in diameter, soaked in 1 N NaOH for 60 sec. ...
Background and purpose: Cyclophosphamide (CP) is a chemotherapy drug extensively used as an antineoplastic agent in treatment of various cancers. However, it is known to cause several adverse effects including reproductive toxicity. Achillea millefolium (AM) is a medicinal plant with potential antioxidant properties. The aim of this investigation was to evaluate the effects of different doses o...
and Applied Analysis 3 However, Wang and Yu 7 showed that Theorem A is not correct when 0 < α < 1. In fact, they proved the following. Theorem C. Suppose 0 < α < 1, x ∈ 0, π and f are 2π-periodic functions of bounded variation on −π,π . Then for n ≥ 2, one has Rn ( f, x ) ≤ 100 α2nα n ∑ k 1 kα−1Vπ/k 0 ( φx ) , 1.10 and there exists a 2π-periodic function f∗ of bounded variation on −π,π and a po...
In this paper we report the results of neutron diffraction measurements of the magnetic structures of a single crystal of DyNi2Ge2 in zero applied magnetic field. There are two distinct magnetic transitions in this material; one is from the paramagnetic phase to an amplitude modulated (AM) antiferromagnetic phase at the Néel temperature, TN = 8.3±0.1 K, and the other is at a lower temperature, ...
