Shocks are often simulated using the classical molecular dynamics (MD) method in which the electrons are not included explicitly and the interatomic interaction is described by an effective potential. As a result, the fast electronic heat conduction in metals and the coupling between the lattice vibrations and the electronic degrees of freedom can not be represented. Under conditions of steep t...

Ca2+ is a ubiquitous signaling messenger mediating many essential cellular functions such as excitability, exocytosis and transcription. Among the different pathways by which cellular Ca2+ signals are generated, the entry of Ca2+ through store-operated Ca2+ release-activated Ca2+ (CRAC) channels has emerged as a widespread mechanism for regulating Ca2+ signaling in many eukaryotic cells. CRAC c...

determination of f-wave latency is a simple and valuable method in evaluating proximal part of peripheral nerves. the aim of this study was to determine the mean minimal peroneal f wave (f min) in healthy individuals. a total of 282 individuals were studied. the mean age was 45.6 years. the f min (± sd) for 564 peroneal nerves was 47.09 ± 4.51 ms. the f min for the age group of 20-45 and height...

The Co0.7-xNixMn0.3Fe2O4 (CNMFO) ferrites with x = 0.00, 0.05, 0.10 and 0.15, PbZr0.52Ti0.48O3 (PZT) ferroelectric 30% CNMFO – 70% PZT magnetoelectric (ME) composites were synthesized by double sintering ceramic method. XRD confirmed the pure phase formation of all compositions ferrite, ME composites. All ferrites, show negative temperature coefficient resistance (NTCR) confirming semiconductin...

We report a case of a 29-year-old man who presented with a distal humeral shaft fracture sustained by blunt trauma. Physicalexamination and nerve conduction study were consistent with injury to the median and radial nerves proximal to theelbow. The patient underwent open reduction and internal fixation of the humeral shaft fracture with neurolysis of the medianand radial nerves. Repeat electrom...

We present the first case of central pontine myelinolysis (CPM) confirmed by high resolution computerized tomography (CT) in which auditory brainstem responses (ABR) revealed impaired conduction beyond the mid pons. The combined use of CT and ABR in the diagnosis of central pontine myelinolysis is discussed.

The non-Fourier effect in heat conduction is important in strong thermal environments and thermal shock problems. Generally, commercial FE codes are not available for analysis of non-Fourier heat conduction. In this study, a meshless formulation is presented for the analysis of the non-Fourier heat conduction in the materials. The formulation is based on the symmetric local weak form of the sec...

In this paper, the combination of conduction with radiation into a semitransparent medium which includes absorption, emission and scattering has been investigated. In order to Study the conduction in medium, the Non-Fourier heat conduction has been applied. In this model there is a time delay between heat flux and temperature gradient. Also, in contrast with Fourier heat conduction, the speed o...

CONTEXT Guillain-Barré syndrome (GBS) is the foremost cause of acute, generalized, peripheral neuropathic weakness. Although nerve conduction studies are a diagnostic aid, the characteristic electrical changes may not evolve for several weeks. Early diagnosis of GBS is important, however, because early treatment has been shown to improve outcome. OBJECTIVES To describe the electrodiagnostic a...

Different aspects of the intrinsic regulation of rate-induced variations of functional refractory period of atrioventricular node (FRPN) were studied in isolated rabbit heart preparations. First, the hypothesis that these variations originate from the net interaction between facilitation and fatigue was tested. For a constant fast rate, selective effects of facilitation and of steady-stage fati...
