به نظر می رسد افزایش میزان پروتئین و فعالیت آنزیم پراکسیداز و فنل کل در ارقام مقاوم می تواند به عنوان معیار انتخاب در مراحل اولیه گزینش برای مقاومت به این ویروس در نظر گرفته شود.

Background This study aimed to assess the impact of perinatal high-fat (HF) diet in female Sprague-Dawley rats (F0) on glucose metabolism and islet function in their early life of second-generation of offspring (F2). Methods F0 rats were fed with a standard chow (SC) or HF diet for 8 weeks before mating, up to termination of lactation for their first-generation of offspring (F1-SC and F1-HF)....

Identification of place of articulation in the synthesized syllables /bi/, /di/, and /gi/ was examined in three groups of listeners: (a) normal hearers, (b) subjects with high-frequency sensorineural hearing loss, and (c) normally hearing subjects listening in noise. Stimuli with an appropriate second formant (F2) transition (moving-F2 stimuli) were compared with stimuli in which F2 was constan...

In the present paper we study the structure of cyclic DNA codes of even length over the ring F2 + uF2 + u 2 F2 where u 3 = 0. We investigate two presentations of cyclic codes of even length over F2 + uF2 + u 2 F2 satisfying the reverse constraint and the reverse-complement constraint.

The 2f1-f2 distortion product otoacoustic emission (DPOAE) is thought to arise primarily from the complex interaction of components that come from two different cochlear locations. Such distortion has its origin in the nonlinear interaction on the basilar membrane of the excitation patterns resulting from the two stimulus tones, f1 and f2. Here we examine the spatial extent of initial generatio...

A smooth, projective, absolutely irreducible curve of genus 19 over F2 admitting an infinite S-class field tower is presented. Here S is a set of four F2-rational points on the curve. This is shown to imply that A(2) = limsup#X(F2)/g(X) ≥ 4/(19 − 1) ≈ 0.222. Here the limit is taken over curves X over F2 of genus g(X)→∞.

This study investigated speaker sex differences in F2 Locus equations (F2 LEs) based on linearly (Hz) and tonotopically (Bark) scaled formant measurements. F2 data based on English monosyllabic words produced by thirteen women and eleven men were tonotopically scaled [20, 21] and F2 LEs were derived for both the linear and tonotopically scaled formant values. Although the overall sex difference...

This paper presents the data on the anticipatory coarticulation of C2 and V2 on V1 in V1#C2V2 sequences in Standard Chinese. Electropalatographic measures and F2 trajectory were obtained to define the articulatory and F2 targets for V1 as well as the displacement for articulatory and F2 transition of V1. Results show that the articulatory target is affected only by C2 place, while C2 place, C2 ...
