This article presents an iterative scheme for solution of the viscous Cahn-Hilliard equation. The procedure is based on the Variational Iteration Method (VIM) in which the solutions are calculated in the form of a convergent series with easily computable components. A good agreement is observed between the present solutions and that obtained by other iterative methods like Adomian Decomposition...

An Escherichia coli strain exhibiting decreased susceptibility to carbapenems was isolated from a hospitalized patient in Greece. The strain carried a self-transferable plasmid coding for metallo-beta-lactamase VIM-1. bla(VIM-1), along with aacA7, dhfrI, and aadA, was included as a gene cassette in a novel class 1 integron. A Citrobacter freundii ampC-derived gene, not associated with the integ...

The aim of this paper is to solve numerically the Cauchy problems nonlinear partial differential equation (PDE) in a modified variational iteration approach. standard method (VIM) first studied before modifying it using Adomian polynomials decomposing terms PDE attain new iterative scheme (MVIM). VIM was used iteratively determine parabolic obtain some results. Also, PDEs with aid Maple 18 soft...

Spasmodic dysphonia (SD) is a neurological disorder of the voice where a patient's ability to speak is compromised due to involuntary contractions of the intrinsic laryngeal muscles. Since the 1980s, SD has been treated with botulinum toxin A (BTX) injections into the throat. This therapy is limited by the delayed-onset of benefits, wearing-off effects, and repeated injections required every 3 ...

Essential tremor can be suppressed with chronic, bilateral deep brain stimulation (DBS) of the ventralis intermedius nucleus (Vim), the cerebellar receiving area of the motor thalamus. The goal in this study was to correlate the location of the electrodes with the clinical efficacy of DBS in a patient with essential tremor. The authors report on a woman with essential tremor in whom chronic bil...

OBJECTIVE We described an organized, on-site medical response for a large-scale urban marathon event and documented illness/injury rates as well as ambulance transfer rates at the Vancouver International Marathon (VIM). METHODS Case-series report of medical encounters was documented prospectively over a 6-yr period at the VIM. The planning and organization of the on-site medical response is t...

Abstract: The traditional perturbation methods depend on a small parameter which is difficult to be found for real-life nonlinear and linear problems. To overcome address this shortcoming, two new powerful recent analytical methods are introduced to solve heat transfer problems in this work. One is He's variational iteration method (VIM) and the other is He’s homotopy-perturbation method (HPM)....

BACKGROUND The ventralis intermedius (VIM) nucleus of the thalamus is the primary surgical target for treatment of tremor. Most centers rely on indirect targeting based on atlas-defined coordinates rather than patient-specific anatomy, making intraoperative physiological mapping critical. Detailed identification of this target based on patient-specific anatomic features can help optimize the su...

This paper investigates the implementation of Variational Iteration Method (VIM) to practical and higher order nonlinear equations in kind of Korteweg-de-Vries (KdV) equation. The obtained solutions from thirdand fourth-order modified KdV are compared with the exact and Homotopy Perturbation Method (HPM) solutions. Results illustrate the efficiency and capability of VIM to solve high order nonl...
