In 1995 Magnus [15] posed a conjecture about the asymptotics of the recurrence coefficients of orthogonal polynomials with respect to the weights on [−1, 1] of the form (1− x) (1 + x) |x0 − x| × { B, for x ∈ [−1, x0) , A, for x ∈ [x0, 1] , with A,B > 0, α, β, γ > −1, and x0 ∈ (−1, 1). We show rigorously that Magnus’ conjecture is correct even in a more general situation, when the weight above h...
Lactobacillus (L. casei) Zhang is a koumiss-originated probiotic strain, which was used as a model in a long-term antibiotics-driven evolution experiment to reveal bacterial evolutionary dynamics; and we isolated gentamycin-resistant L. casei Zhang descendents. To decipher the gentamycin resistance mechanism, here we cultivated the parental L. casei Zhang and its descendent cells in an antibiot...
BACKGROUND The ability to determine the direction of a sound source is based on the fact that sounds reach both cars at different times, phase, intensity and/or frequency. The perception of a sound source favors speech intelligibility in noisy environments. AIM To identify the minimum time of interaural delay--produces lateralization to the car which the stimulus reached first--through ascend...
We study the holomorphic Euler characteristics of tautological sheaves on Hilbert schemes points surfaces. In particular, we establish rationality K-theoretic descendent series. Our approach is to control equivariant over scheme affine plane. To do so, slightly modify a Macdonald polynomial identity Mellit.
تاثیر آموزش تفکر انتقادی به شیوه مباحثه بر روی مهارت درک متن یادگیرندگان انگلیسی به عنوان زبان خارجی
the purpose of the present study was to investigate the effect of instruction through debate on male and female efl learners’ reading comprehension, to examine the differences between the performance of male and female participants on the five dimensions of cctst including analysis, evaluation, inference, deductive reasoning, and inductive reasoning, and to examine the differences between male ...
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...
this is an original study on the effect of a polyisobutylene – polydimethylsiloxane (pibpdms) block copolymer modifier used as an interfacial active agent on the dynamics behaviour of single newtonian drops suspended in a polyisobutylene (pib) newtonian matrix. the results were divided in two sections. the first part included the experiments carried out on the non-modified and 2% block cop...
