Let D be a digraph, V (D) and A(D) will denote the sets of vertices and arcs of D, respectively. A (k, l)-kernel N of D is a k-independent set of vertices (if u, v ∈ N then d(u, v), d(v, u) ≥ k) and l-absorbent (if u ∈ V (D) \N then exists v ∈ N such that d(u, v) ≤ l). A k-kernel is a (k, k − 1)-kernel. We propose an extension of the definition of (k, l)-kernel to (arc-)weighted digraphs, verif...

This article describes an analysis tool aimed at the C code of the Linux kernel, having been first described as a prototype (in this forum) in 2004. Its continuing maturation means that it is now capable of treating millions of lines of code in a few hours on very modest platforms. It detects about two uncorrected deadlock situations per thousand C source files or million lines of source code i...

an experiment was conducted to determine the effect of five plants densities (100,200,300,400 and 500 grain m-2) on yield and its components in three rain fed barley cultivars (ezeh, mahor and dopar). a factorial experiment based on randomized complete block design with three replications was conducted in agricultural research center of khorramabad city in the east of iran (in 2006-2007). in th...

in this research, we studied physical, chemical and biochemical characteristics of pistachio entitled pistacia vera cv. daneshmandi and was compared to three pistachio including of badami sefid, kalle ghoochi and akbari. the examined characteristics were fresh and dry weight of seed, green shell and also kernel, weight of hard shell, seedless and early opening nut, comparing the seed and kernel...

Abstract The purpose of the research is to study effect microbiological preparations on quality winter wheat in northern forest-steppe zone Tyumen region. article provides following preparations: “Double roots” (Healthy roots)” “Organic”, as well their combined use. largest increase thousand kernel weight was noted option 1 and 3 roots roots) + Organic” by 4.2-2.5 g, which 7.8-13.3% from contro...

Temperature and moisture are essential factors in germination seedling growth. The purpose of this research was to assess the growth wheat (Triticum aestivum L.) seeds under various abiotic stressors. It conducted Agronomy Institute Hungarian University Agriculture Life Sciences, Gödöllő, Hungary. Six distinct temperature levels were used: 5, 10, 15, 20, 25, 30 °C. Stresses drought waterlogging...

To investigate the effect of irrigation and urea levels on some agronomic traits essential oil content pot marigold, a study was conducted in split-plot based completely randomized block design with three replications. The treatments included four (irrigation after 5, 10, 15, 20 days) nitrogen (0, 80, 160, 240 kg ha-1 urea). plant height, flower number, dry weight, number seeds/head, thousand k...
