Bunium persicum (Boiss.) is an economically important medicinal plant growing wild in arid regions in Iran. The essential oil of B. persicum (EOBP) was extracted using hydrodistillation. A total of eighteen compounds, representing 96.14 % of the oil was identified by gas chromatography/mass spectrometry (GC/MS).The main compounds were cuminaldehyde (23.04 %), gamma-terpinene (14.48 %), trans-3...

The classic GI=G=1 queueing model of which the tail of the service time and/or the interarrival time distribution behaves as t ?v S(t) for t ! 1, 1 < v < 2 and S(t) a slowly varying function at innnity, is investigated for the case that the traac load a approaches one. Heavy-traac limit theorems are derived for the case that these tails have a similar behaviour at innnity as well as for the cas...

A bstract Asymptotic symmetries in Carrollian gravitational theories 3+1 space and time dimensions obtained from “magnetic” “electric” ultrarelativistic contractions of General Relativity are analyzed. In both cases, parity conditions needed to guarantee a finite symplectic term, analogy with Einstein gravity. For the magnetic contraction, when Regge-Teitelboim imposed, asymptotic described by ...

in this paper, the notion of cyclic $varphi$-contraction in fuzzymetric spaces is introduced and a fixed point theorem for this typeof mapping is established. meantime, an example is provided toillustrate this theorem. the main result shows that a self-mappingon a g-complete fuzzy metric space has a unique fixed point if itsatisfies the cyclic $varphi$-contraction. afterwards, some results inco...

If $G$ is a connected graph with vertex set $V$, then the eccentric connectivity index of $G$, $xi^c(G)$, is defined as $sum_{vin V(G)}deg(v)ecc(v)$ where $deg(v)$ is the degree of a vertex $v$ and $ecc(v)$ is its eccentricity. In this paper we show some convergence in probability and an asymptotic normality based on this index in random bucket recursive trees.

Asymptotic couples (of H-type) try to capture the structure induced by the derivation of a Hardy field K on the value group of the natural valuation on K. In this note we continue the study of algebraic and model-theoretic aspects of asymptotic couples undertaken in [1]. We give a short exposition of some basic facts about asymptotic couples, and address a few topics left out in that paper: the...

Abstract Using the notion of strict h-contraction, existence results for Ψ-asymptotic equivalence two pairs (Lyapunov) matrix differential equations with integral term as right side and modified argument are given.

In this paper, we investigate infinite product representation of the solution of a Sturm- Liouville equation with an indefinite weight function which has two zeros and/or singularities in a finite interval. First, by using of the asymptotic estimates provided in [W. Eberhard, G. Freiling, K. Wilcken-Stoeber, Indefinite eigenvalue problems with several singular points and turning points, Math. N...
