septoria tritici blotch is an important wheat disease in many areas of the world including iran's warm, humidregions. in this study, crosses were made between resistant breeding line bobwhite#1/fengkang andcommercial cultivars moghan3, koohdasht, tajan and morvarid, and derived f1, f2, bc1 and bc2 generations were used to determine the genetic control of necrosis, pycnidia traits and the area u...

If α is an irrational number, we define Yoccoz's Brjuno function Φ by Φ(α) = n≥0 α 0 α 1 · · · α n−1 log 1 αn , where α 0 is the fractional part of α and α n+1 is the fractional part of 1/αn. The numbers α such that Φ(α) < ∞ are called the Brjuno numbers. The quadratic polynomial Pα : z → e 2iπα z + z 2 has an indifferent fixed point at the origin. If Pα is linearizable, we let r(α) be the conf...

Little information is available on the genetics of physiological traits for drought tolerance in Indian mustard. Generation mean analysis was performed using two crosses (Maya x BPR543-2) and (BPR543-2 x BPR2) to study the nature and magnitude of gene effects on seed yield and physiological characters in Indian mustard. The F1, F2, BC1 and BC2 of these crosses, along with P1 and P2, were studie...

Currently, the available algorithms for unbiased structure searches are primarily atom-based, where atoms are manipulated as the elementary units, and energy is used as the target function without any restrictions on the bonding of atoms. In fact, in many cases such as nanostructure-assembled materials, the structural units are nanoclusters. We report a study of a bonding-restricted structure s...

This paper describes the creation of a cDNA microarray for annual sunflowers and its use to elucidate patterns of gene expression in Helianthus annuus, Helianthus petiolaris, and the homoploid hybrid species Helianthus deserticola. The array comprises 3743 ESTs (expressed sequence tags) representing approximately 2897 unique genes. It has an average clone/EST identity rate of 91%, is applicable...

We study the superconducting properties of the noncentrosymmetric compound LaNiC2 by measuring the London penetration depth 1k(T ), the specific heat C(T, B) and the electrical resistivity ρ(T, B). Both 1λ(T ) and the electronic specific heat Ce(T ) exhibit behavior at low temperatures that can be described in terms of a phenomenological two-gap Bardeen–Cooper–Schrieffer (BCS) model. The residu...

The facet-analytic paradigm is probably the most distinct approach to knowledge organization within Library and Information Science, and in many ways it has dominated what has be termed ‘‘modern classification theory’’. It was mainly developed by S.R. Ranganathan and the British Classification Research Group, but it is mostly based on principles of logical division developed more than two mille...

PURPOSE In the pretargeted antibody-guided radioimmunotherapy (PAGRIT) system, the combined use of two different antibodies directed against the same tumor antigen could represent a valid approach for improving tumor targeting and therapeutic efficacy. We developed a novel monoclonal antitenascin antibody, ST2485, and studied its biochemical and functional properties by in vitro and in vivo ass...
