plastic instability which results in the localization and failure of sheet metals has been studied in equibiaxial stretching of commercial purity aluminium sheet. attention was focussed on two main industrial conditions of the material. these were representative of the materials that could be processed by the commercial batchannealing process (slow heating, long time) or by a continuous anneali...
Cognition, thoughts, and beliefs play a basic role in marriage and relationships couples. Recognize these can be helpful to identify the foregrounds of marital instability.The aim of this study was to investigate the relationship between communicational beliefs and degree of marriage instability among the female and male married. The study method is survey research and the stat...
Exchange rate instability brings about significant changes in the domestic and foreign sectors that can impose negative effects on the whole economy. The present study investigates the effect of exchange and inflation rate instability on the lending behavior of Iranian banks by using data of the 10 banks over the time period 1382-1397(2003-2018). To do this, at first, a GARCH(1,1) of the exchan...
the presence of van der waals (vdw) force can lead to mechanical instability in freestanding nano-scale actuators. most of the previous researches in this area have exclusively focused on modeling the instability in actuators with one actuating components. while, less attention has been paid to actuators consist of two actuating components. herein, the effect of the vdw force on the instability...
in this study a nonlinear asymmetric instability analysis carried out to study primary atomization of annular liquid sheets emanating from the prefilming airblast atomizer using a perturbation method and potential flow assumption. in this direction, firstly governing equations derived according to potential flow assumption and conservation equations while dynamic and static boundary condition a...

Propagation of Electromagnetic wave in a plasma in the equilibrium state can cause instability. Investigating the situations in which this kind of instability occurs and grows is an important issue. In this paper, Raman instability in plasma is analyzed by particle simulation method. In terms of physical investigation, plasma is a very complicated environment and experimentally too expensive. ...
Objective The Objective Ankle sprains are among the most common injuries in athletes. One of the limitations of people with chronic ankle instability is the lack of postural control. Balance and coordination training are among the most common interventions for people with chronic ankle instability. Therefore, the aim of this study was to investigate the effect of balance training on postural co...
Abstract Background: The polymorphic variants at codon 72 of the p53 gene, encoding either proline or arginine at residue 72, produce marked change in the structure of p53. From the evidence that the DNAmismatch repair system and p53 interact to maintain genomic integrity, we hypothesized that the codon 72 variation may influence the prevalence of microsatellite instability a featur...
in the current study the effect of casimir force and squeezed film damping on the pull-in instability and dynamic behavior of electrostatically actuated nano and micro electromechanical systems is investigated separately. linear elastic membrane theory is used to model the static and dynamic behavior of system for strip, annular and disk geometries. squeezed film damping effect is modeled using...
