study of cohesive devices in the textbook of english for the students of apsychology by rastegarpour
this study investigates the cohesive devices used in the textbook of english for the students of psychology. the research questions and hypotheses in the present study are based on what frequency and distribution of grammatical and lexical cohesive devices are. then, to answer the questions all grammatical and lexical cohesive devices in reading comprehension passages from 6 units of 21units th...
Dynamical stripe structure in La2−xSrxCuO4 observed by Raman scattering
The dynamical stripe structure relating to the ”1/8 problem” was investigated in La2−xSrxCuO4 utilizing the high frequency response of Raman scattering. The split of the two-magnon peak due to the formation of the stripe structure was observed at whole Sr concentration region from x = 0.035 to 0.25 at low temperatures. Especially clear split was observed at low carrier concentration region x = ...
متن کاملGiant magneto-optical Raman effect in a layered transition metal compound.
We report a dramatic change in the intensity of a Raman mode with applied magnetic field, displaying a gigantic magneto-optical effect. Using the nonmagnetic layered material MoS2 as a prototype system, we demonstrate that the application of a magnetic field perpendicular to the layers produces a dramatic change in intensity for the out-of-plane vibrations of S atoms, but no change for the in-p...
متن کاملRaman scattering in doped transition metal pentatellurides
We have measured the Raman spectra of Sb doped (ZrTe52xSbx ; 0,x,0.25) and Hf doped (ZryHf12yTe5 ; 0,y,1) pentatellurides in the 90–300 cm 21 range, and compared them to the corresponding spectrum for the parent material ZrTe5 . X-ray diffraction data revealed that the pentatelluride structure prevails at all doping concentrations. With increasing Sb concentration, the linewidths for three of t...
متن کاملInvestigation of Scalar Modulation Instability in the Presence of Raman Scattering in Photonic Crystal Fibers
In this paper, by including Raman scattering in the coupled-mode equations, the scalar modulation instability in photonic crystal fibers is investigated. The evolution of the pump, Stokes and anti-Stokes waves along the fiber as well as the conversion efficiency for two cases, with and without Raman effect, are studied. The effect of anti-Stokes seed and the pump depletion on the evolution of S...
