ABSTRACT Partial resistance to Septoria tritici blotch (STB) and its inheritance were investigated in a doubled-haploid population of a cross between cvs. Arina and Riband. The former has good partial resistance whereas the latter is susceptible. In adult plant trials in polytunnels, STB disease scores were negatively correlated with heading date. Resistance was not specific to any of the three...

An 8-year old boy with a small goiter, normal basal metabolic rate (BMR), and elevated serum thyroid hormone levels (thyroxine [T(4)] 19.5 mug per 100 ml, free T(4) 4 ng per 100 ml, triiodothyronine [T(3)] 505 ng per 100 ml) was studied. He had measurable serum thyroid-stimulating hormone (TSH) levels (average 5.5 muU per ml), and the thyroxine-binding proteins, hearing, and epiphyseal structur...

background and aims. the mechanical properties of fiber-reinforced composite fixed partial dentures (fpds) are affected by fiber impregnation. the aim of this in vitro study was to compare the fracture resistance of composite fixed partial dentures reinforced with pre-impregnated and non-impregnated fibers. materials and methods. groups (n=5) of three-unit fiber-reinforced composite fpds (23 mm...

The appearance of resistance to a number of hepatotoxins in primary cultures of hepatocytes prepared at various time intervals up to 2 weeks after partial hepatectomy is the major focus in this study. Resistance to the cytocidal effect of aflatoxin B1, 2-acetylaminofluorene, N-hydroxy-2-acetylaminofluorene, methotrexate, or methyl methanesulfonate shows a progressive increase until 48 hr and th...

The rice Xa21 gene that confers resistance against Xanthomonas oryzae pv oryzae encodes a receptor-like kinase protein consisting of a presumed extracellular domain, a transmembrane domain and a cytoplasmic protein kinase. To determine if the XA21 kinase domain is essential for transducing the defense response, we mutated the Lysine 736 of Xa21 to Glutamic acid (K736E) to construct XA21K736E. T...

To analyze the transport process, a formalism was developed similar to charge carrier transport in crystalline materials. Classical electrostatic and electrodynamics treatment with specific boundary conditions were employed. The spreading velocities and deep trapping times were evaluated. By this method we determined the dispersive and spatiotemporal features of the transient charge packets in ...

Abstract We consider linear partial differential equations on resistance spaces that are uniformly elliptic and parabolic in the sense of quadratic forms involve abstract gradient divergence terms. Our main interest is to provide graph metric approximations for their unique solutions. For families with different coefficients a single compact space we prove solutions have accumulation points res...
