چکیده زمینه و هدف: گیاهان بیلهر، زنیان و سنبله ی کرکدار در طب سنتی ایران به ویژه در کهگلویه و بویراحمد استفاده میشوند. هدف این مطالعه بررسی اثرات این گیاهان بر تکثیر سلولهای الیگودندروسیت مغز موش صحرایی است. روش بررسی: با استفاده از اتانول 50 درصد از گیاهان مذکور عصاره ی آبی الکلی خیسانده تهیه شد. سلول های رده ی الیگودندروسیت مغز (oln-93) برای 24 ساعت با غلظت های مختلف این عصاره ها تیمار شدن...
In a letter to the Editor of Science (176, 966, 1972), Professor Szent-Gyorgyi described his approach to science as Dionysian. This little book provides some further insight into the meaning of this statement. In 114 pp. he writes about some of his research interests over the past half century. This account does not describe the work in much experimental detail, but rather tries to give the mot...
Several inversion modeling-based approaches have been developed/used to extract soil hydraulic properties (α, n, θres, θsat, Ksat) from remotely sensed (RS) soil moisture footprints. Hydrological models with shallow ground water (SGW) table depths in soils simulate daily root zone soil moisture dynamics based on the extracted soil parameters. The presence of SGW table depths in soils significan...
In thb paper, we study the problem of drawing a graph in the plane so that edger appear aa straight lines and so that the "um angle formed by any pair of incident edges is " k e d . We define the rerolution of a layout to be the s t e of the minimum &e fonned by incident edges of the graph, and the resolution of a graph to be the d u m raohtion of any layout of the graph. We characterise the re...
State Machine Semantics of SDL Uwe Glasser (Heinz Nixdorf Institut Universitat-GH Paderborn, Germany [email protected]) Ren e Karges (metronet GmbH Koln, Germany [email protected]) Abstract: Based on the ITU-T Recommendation Z.100 [27]|also known as SDL-92| we de ne a formal semantic model of the dynamic properties of Basic SDL in terms of an abstract SDL machine. More precisel...
obvious is Inot signiificaint, beinig about 1.4 timles its stanidard deviation. If this insignificant trend be removed, the residuals have a Lexian ratio of 1. The calculations have beein carried to only the three places givein anid therefore the last place in the atverages is not certaiin. 6 A single case so isolated raises some aininoying statistical problems; it accounts for more than 3 mont...
Let jp „ denote the nth positive zero of J , p > 0. Then / ■■> 7\'/2 Jp.n > Oln + P) ■ We begin by considering the eigenvalue problem (1) -(•*/)' + x~y = X2x2p-Xy, X,p>0, (2) y(a) =y(\) = 0, 0 < a < 1. For simplicity of notation we will set q = p~x. It is easily verified that the general solution of (1) is y(x) = CxJq(Xqxx/q) + C2Yq(Xqxx'q) and that the eigenvalues are given by Jq(Xq)Yq(Xqax/q)...
Angewandte Mathematik Und Informatik Universit at Zu K Oln on the Sqap-polytope on the Sqap-polytope
The study of the QAP-Polytope was started by Rijal (1995), Padberg and Rijal (1996), and J unger and Kaibel (1996), investigating the structure of the feasible points of a (Mixed) Integer Linear Programming formulation of the QAP that provides good lower bounds by its continious relaxation. Rijal (1995) and Padberg and Rijal (1996) propose an alternative (Mixed) Integer Linear Programming formu...
