In this lecture, we will talk about the emergence of the giant component in the Erdös-Rényi random graph model G(n, p). In this model, a graph G ∈ G(n, p) on n vertices is chosen by placing an edge between each pair of vertices independently with probability p. A series of seminal paper by Erdös and Rényi from 1959-61 [1, 2, 3] helped to develop the theory behind this model. One of their key co...
The matching condition which determines the effect of a heavy quark threshold on the running of the QCD coupling α M S is reviewed. The matching scale is arbitrary to some extent. However, this affects the value of α M S away from the threshold region only marginally. 1 Talk given at the workshop on " Determinations of α s from inclusive observables " , Aachen, April 94.
Here, we report the genome sequence of Magnetospirillum magnetotacticum strain MS-1, which consists of of 36 contigs and 4,136 protein-coding genes.
وضع قواعد حاکم بر حمل و نقل دریایی کالا در سطح بین المللی به لحاظ آثار متعدد آن نسبت به صاحبان کالا و صاحبان ناوگان دریایی از اهمیتی ویژه برخوردار است. به همین جهت کشورها نسبت به این قواعد حساسیتی خاص دارند. در سایه تلاش کشورهای ذی نفع در سال 1924 قواعد لاهه حاکم بر این نوع حمل و نقل شکل گرفت که در حال حاضر منبع اصلی قوانین داخلی بسیاری از کشورهاست. این قواعد در سال 1968 مورد اصلاح قرار گرفت که...
the effect of in planta tiba and proline on in vitro seedlings and cell culture of sugar beet was investigated. sterilized seeds were grown in vitro on ½ strength ms medium supplemented with 0 or 3 mg/l tiba. calli obtained on young leaves cultured on ms medium containing 1 mg/l bap, were used for the intiation of cell suspension cultures using ms basal composition supplemented with 0 or 50 m m...
in this thesis, phosphorus ylides [phbppy], [no2bppy] and [brbppy] have been synthesized through the formation of phosphonium salt and dihydrogenation, followed by the reaction of pd(oac)2 and the orthopalladated dinuclear complexes [pd(?-cl)(phbppy)]2, [pd(?-cl)(no2bppy)]2 and [pd(?-cl)(brbppy)]2 have been produced. the reaction of dinuclear complexes and bidentate ligands [l = bipy (2,2-bipyr...
