OBJECTIVES To assess the detectability of a low-signal-intensity line within adenomyosis lesions adjacent to the endometrium on apparent diffusion coefficient (ADC) maps, and to establish correlations between these lesions and their possible causes, and more particularly the hormonal changes and magnetic resonance (MR) factors. MATERIALS AND METHODS MR images were obtained from 110 patients w...
abstract due to the growing importance and influence of the self of the teacher in the field of educational and cognitive psychology, the current study intended to investigate the relationship between three teacher qualities and characteristics, i.e. teacher self efficacy, self regulation, and success as perceived by their learners. the study aimed at finding whether teacher self efficacy an...
Plants are generally subjected to a combination of different conditions such as magnetic field and soil bacteria in their life. The present investigation tried to compare the effects and interactions of magnetic field and rhizobial inoculant in alfalfa. A pot experiment was performed under a natural condition by a factorial design to ...
The objective of this work is to study the effect of two key factors external magnetic field and applied current density during template-based electrodeposition of nickel nanowires using an electrode distance of 20 mm. Morphology, length, crystallite size and crystallographic characterization of the grown nickel nanowires at an electrode distance of 20mm are presented. For this electrode distan...
Time and Intensity of Electromagnetic waves impacts on the Growth phase of Escherichia coli bacteria
Background: Electromagnetic fields have various effects on the biochemical and cellular behavior of microorganisms due to radiation. It is necessary to investigate more extensively the effects of these magnetic fields on some microorganisms, such as bacteria. The purpose of this study was tp investigate the effects of magnetic fields on Escherichia coli bacteria (PTCC 1330). Materials and Meth...
The objective of this paper is to present a procedure based on moving (or shifting) isoparametric elements for the analysis of dynamic crack propagation. The fracture parameters, such as the stress intensity factors or energy release rates for dynamically propagating cracks, are evaluated by far-field path-independent integrals that were recently derived by the authors. The combined use of the ...
In this paper, errors involved in extracting stress intensity factors from photoelastic fringe pattern, which were simulated for crack estimated. The estimated errors do not contain the errors associated with the optical apparatus, but only consist of the errors associated with discretization and extraction of data for SIF’s calculation to accomplish that. A series of fringe pattern were simula...
