Induction motors need to be monitored regularly because it involves the company's productivity. The induction motor monitoring method in this study uses a current variable which is transformed using Discrete Wavelet Transform. Transform (DWT) used results are satisfactory for detecting short circuit stator winding of an motor. Of many types and levels discrete wavelet transforms, haar transform...

pretreatment of adults of iraq strain of afhstephenst with a sub-letlial dose of pcrmethrin resulted in a 65% enliancemenl of tolerance to this insecticide. similarly, pre-exposure of dub-lpr larvae to a sub-lethal dose of pcrmethrin resulted in increased tolerance to pcrmethrin. for the sensitive ind-s strain, the inductive effect was smaller. tiie results of bioassays of resistant and suscept...

In this paper we establish rigorously that the family of Burgers vortices of the three-dimensional Navier-Stokes equation is stable for small Reynolds numbers. More precisely, we prove that any solution whose initial condition is a small perturbation of a Burgers vortex will converge toward another Burgers vortex as time goes to infinity, and we give an explicit formula for computing the change...

A dynamical system is called “chaotic” if small changes to its initial conditions can create large changes in its behavior. By analogy, call a dynamical system “structurally chaotic” if small changes to the equations describing the evolution of the system produce large changes in its behavior. Although there are many definitions of “chaos”, there are few mathematically precise candidate definit...

background: the effect of smoking cigarettes is followed by diverse effects on ovaries and developing follicles but the effect of passive smoking on ovarian function is unknown. on the other hand, the ovarian response to induction is a very important step in assisted reproduction. the aim of this study is to compare ovarian response in passive smokers and non-passive smokers in an assisted repr...

abstract objective: previous studies have indicated the hyperglycemia-induce cell death in various tissues such as brain, kidneys, liver and especially in the testis. recent studies have reported that diabetes can trigger male infertility. in this study we report the histological analysis of the testis tissue after diabetes type 1 induction in wistar rats. materials and methods: at various time...
