in this study, a feasible green method for the synthesis of copper oxide nanocrystalline is described by using sour cherry juice which has a significant effect on crystalline size, and morphology. the benefits of the green method, not only nanometer scale are formed but also low-cost method are obtained in a normal atmosphere which it has been used (ch3coo)2cu.h2o individually as cu sources. al...

Working with epitaxial films of Fe, we succeeded in independent control of different scattering processes in the anomalous Hall effect. The result appropriately accounted for the role of phonons, thereby clearly exposing the fundamental flaws of the standard plot of the anomalous Hall resistivity versus longitudinal resistivity. A new scaling has been thus established that allows an unambiguous...

This paper presents new approach to enhance the quality of sound signal perceived by the listener in a concert hall considering Spectrogram and Single Spectrum Plot. We simulate a natural concert hall using Digital Echo and Schroeder Reverberator models. We analyze the results using Spectrogram and Single Spectrum Plots and finally propose a model for better analysis of room acoustics.

Distribution data describing the current shea range were obtained from John Hall (University of Wales, Bangor); for details, see previous reports and Vitellaria paradoxa: a monograph (Hall et al., 1996). In 2010, these records were supplemented with shea plot data from Burkina Faso, Mali and Ghana, and with the collection localities of herbarium specimens held at the Royal Botanic Gardens, Kew ...

We call Poincaré time the time associated to the Poincaré (or first return) map of a vector field. In this paper we prove the non-accumulation of isolated critical points of the Poincaré time T on hyperbolic polycycles of polynomial vector fields. The result is obtained by proving that the Poincaré time of a hyperbolic polycycle either has an unbounded principal part or is an almost regular fun...

Diffraction peak profiles were calculated numerically for dislocation ensembles with different spatial arrangements and correlations between the Burgers vector signs. The latter property determines stored elastic energy in crystal width of diffraction peaks. It is shown that within approximation asymptotic line-profile theory relationship breadth magnitude modified Williamson-Hall (mWH) plot li...

scanning hall probe microscopy (shpm) is a scanning probe microscopy technique developed to observe and image magnetic fields locally. this method is based on application of the hall effect, supplied by a micro hall probe attached to the end of cantilever as a sensor.  shpm provides direct quantitative information on the magnetic state of a material and can also image magnetic induction under a...
