Abstract Background & Aim: Role transition from nursing student to clinical nurse is a sensitive stage in the nurses’ professional life. Many factors affect role transition and could change its outcome. The present study was designed with the aim of exploring the factors affecting the process of transition from nursing student to clinical nurse using the experiences of b...
General views have usually ignored the relation between the type of civil society and the type of political transitions. To address this shortcoming, the current article has reinvestigated this relation through a comparative study of revolutions in Egypt, Tunisia and Libya. In the framework of this relation, this article has demonstrated that remarkable development of civil society in Tunisia a...
Architecturally, the Seljuqs' dominion makes a significant shift from the Pre-Islamic Sassanid squinches into a sophisticated transition mechanism employed to change the walls of a square chamber to an octagonal base to set a dome which this initiated a new construction methodology to hybridize the previous experiences of Sassanid domes with new architectural tendencies since the previous under...
Consacrer deux journees a la transition, dont une aux approches geographiques de notion transition et seconde plus specifiquement focalisee sur les aspects des transitions energetique ecologique etait certainement un pari d’autant que l’organisation fut tres largement bouleversee par pandemie qui obligea d’abord le report mars septembre-octobre, puis l’obligation d’organiser cette deuxieme jour...
T he main purpose of this article is to analyze exchange rate behavior based on monetary fundamentals in the context of Iranian economy over the period 1990:2 to 2014:3. To do so, two monetary exchange rate models is investigated, the first by regarding interest rate differential as a monetary variable, and the second one regardless of interest rate differential as a monetary variabl...
Structural and electronic properties of double perovskites Sr2BWO6 (B = Co, Ni, Cu) were studied for each of three magnetic configurations nonmagnetic, ferromagnetic, and antiferromagnetic by using density functional theory in generalized gradient approximations (GGA) and strong correlation correction (GGA + U). Due to magnetic transition from antiferromagnetic to nonmagnetic phase, an electr...
In this research, YBa2Cu3O7-d (0 < d < 1) nanocrystalite superconductor was prepared by mechanochemical alloying method. We synthesized YBa2Cu3O7-d via mixing the BaCO3, Y2O3, CuO powders and milling in SPEX 8000 for 5h with weight ratio of ball to powder 10:1 and steel balls of 11mm diameter, followed by heating for 4h at 850 ˚C. The superconductor phase formation process was completed with si...
Obtaining the superconductor samples or mainly, structural phase controlling in 123 systems is a matter of special importance. As decreasing of oxygen in this structure has special effects, and mainly causing structural phase transition, by investigating the structure and thermal analysis of the system, tetragonal-orthorhombic structural phase transition was observed and optimum contents of s...
The performance of any finite element (FE) structural analysis is directly related to the global number of nodes and degrees of freedom (DOF) of the discretized structure and mesh distribution attributes. It is obvious that the appropriate numerical analysis needs finer elements in the zone of interest, e.g. zone of high stress concentration and intensity, and coarser elements for farther porti...
Supervisory control and fault diagnosis of hybrid systems need to have complete information about the discrete states transitions of the underling system. From this point of view, the hybrid system should be abstracted to a Discrete Trace Transition System (DTTS) and represented by a discrete mode transition graph. In this paper an effective method is proposed for generating discrete mode trans...
