Supplement 2 to the paper " Floating bundles and their applications " A.V. Ershov This paper is the supplement to the section 2 of the paper " Floating bundles and their applications " [1]. Below we study some properties of category, connected with cobordism rings of FBSP. In particular, we shall show that it is the tensor category. In [1] the series G(x, y) ∈ H[[x, y]] = Ω * U (Gr), where H = ...

Let v(G) and γ(G) denote the number of vertices and the domination number of a graph G, respectively, and let ρ(G) = γ(G)/v(G). In 1996 B. Reed conjectured that ifG is a cubic graph, then γ(G) ≤ ⌈v(G)/3⌉. In 2005 A. Kostochka and B. Stodolsky disproved this conjecture for cubic graphs of connectivity one and maintained that the conjecture may still be true for cubic 2-connected graphs. Their mi...

in order to study the effects of silver thiosulfate (0.02, 0.05, 0.1 and 0.2 mm), humic acid (100, 500 and 1000 mg l-1), nano silver (5, 10, 25 mg l-1), salisilicacid (1, 2 and 4 mm) and sucrose (1%, 2.5% and 5%) on the vase life and some qualitative characteristics of cut narcissus var duch master floweres, two expriments were counducted in postharvest laboratory of mohaghegh ardabili universi...

abstract- chrysanthemum (dendranthema grandiflorum) is one of the most important ornamental plants used as cut flower, flowering pot plant and groundcover worldwide. in this research, the effects of preservative solutions containing thymol (75 and 125 mg -l), menthol (75 and 125 mg l-1) and eugenol (75 and 125 mg l-1) on the quality and vase-life of chrysanthemum cut flowers at 3±1ºc and 75-80%...

Let v(G) and γ(G) denote the number of vertices and the domination number of a graph G, respectively, and let ρ(G) = γ(G)/v(G). In 1996 B. Reed conjectured that if G is a cubic graph, then γ(G) ≤ dv(G)/3e. In 2005 A. Kostochka and B. Stodolsky disproved this conjecture for cubic graphs of connectivity one and maintained that the conjecture may still be true for cubic 2-connected graphs. Their m...

Rosa persica with a distinctive red eye is a good candidate for addition to the breeding pool of roses. In order to optimize micropropagation of R. persica, three culture media (MS, QL and VS) were compared. The maximum growth rate was observed in the VS medium. Addition of FeEDTA (Fe: 65.4 mg/l), calcium gluconate (Cg: 2.7 g/l) and Gamborg vitamins (B5) instead of VS vitamins, alone or in comb...
