This study is conducted with the aim of explaining the role of extraversion on employee loyalty with the mediating role of career and social adaptability among employees in a private organization. The research design is descriptive-correlational and the population is the employees of Saveh Chocolate Factory up to 240 people. According to Cochran's formula, the sample size of eligible people in ...

For a Denjoy homeomorphism f of the circle S, we call a pair of distinct points of the ω-limit set ω(f) whose forward and backward orbits converge together a gap, and call an orbit of gaps a hole. In this paper, we generalise the Sturmian system of Morse and Hedlund and show that the dynamics of any Denjoy minimal set of finite number of holes is conjugate to a generalised Sturmian system. More...

Background: Increased number of intestinal intraepithelial lymphocytes (IELs) is a key histological finding in the diagnosis of celiac disease (CD); however, the number of IELs in celiac patients and healthy subjects may vary from one region to another. Additionally, there are some seronegative celiac patients with a borderline histology. Objective: To determin...

BACKGROUND Regional lung sound intensity in chronic obstructive pulmonary disease (COPD) patients is influenced by the severity and distribution of emphysema, obstructed peripheral airways, and altered ribcage and diaphragm configurations and movements due to hyperinflation. Changes in the lung sound distribution accompanied by pulmonary function improvements in COPD patients were observed afte...

The relationship ρL(G) ≤ ρ(G) ≤ γ (G) between the lower packing number ρL(G), the packing number ρ(G) and the domination number γ (G) of a graph G is well known. In this paper we establish best possible bounds on the ratios of the packing numbers of any (connected) graph to its six domination-related parameters (the lower and upper irredundance numbers ir and IR, the lower and upper independenc...

By pouring equal balls into a container one obtains disordered packings with fascinating properties which might shed light on several elusive properties of complex materials such as amorphous metals or colloids. In any real experiment with equal-sized spheres one cannot reach packing fractions (fraction of volume occupied by the spheres respect to the total volume, ρ) below the Random Loose Pac...

Given a set S of n points in the plane, the reflexivity of S, ρ(S), is the minimum number of reflex vertices in a simple polygonalization of S. Arkin et al. [4] proved that ρ(S) ≤ ⌈n/2⌉ for any set S, and conjectured that the tight upper bound is ⌊n/4⌋. We show that the reflexivity of any set of n points is at most 3 7n+ O(1) ≈ 0.4286n. Using computer-aided abstract order type extension the upp...

We discuss a simple method to evaluate the QCD corrections to ∆ρ. It assumes that the perturbative expansion in terms of MS parameters is meaningful and, unlike other studies, exploits significant available information concerning O(ˆ α 2 s) corrections. This approach leads to an enhancement of ∼ 26% relative to the conventional evaluation. QCD corrections to the Z 0 → b ¯ b amplitude are also c...

We present a singularity free class of inhomogeneous cylindrical universes filled with stiff perfect fluid (ρ = p). Its matter free (ρ = 0) limit yield two distinct vacuum spacetimes which can be considered as analogues of Kasner solution for inhomogeneous singularity free spacetime.
