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...
Variation in acoustic overstimulation changes tinnitus characteristics
Tinnitus often occurs after exposure to loud noise. This raises the question of whether repeated exposure to noise increases the risk of developing tinnitus. We thus studied tinnitus development after repeated acoustic overstimulation using startle and auditory brainstem-response techniques applied to Mongolian gerbils. Noise with bandwidths ranging from 0.25 up to 0.5 oct were used for repeate...
متن کاملInvestigation of Volumetric and Acoustic Properties of Ionic Liquid + Amino Acid + Water Systems at Different Temperatures
This paper reports density and speed of sound data for solutions of the ionic liquids (ILs) [C4mim]Cl and [C4mim][CF3SO3] in aqueous solution of 0.05 w/w amino acids of alanine, serine and proline at T = (288.15, 298.15, 308.15 and 318.15) K. From the experimental data measured, the apparent molar volume (Vϕ), isentropic compressibility ( ), and apparent molar isentropic compression ( ) have be...
متن کاملA Simulation Study of Multi-path Characteristics of Acoustic Propagation in the Strait of Hormuz
Multi-path interference due to boundary reflection in shallow water acoustic communication poses a major obstacle to reliable and high-speed underwater communication system. In this study, initially 3D variations of field data such as sound speed, temperature and salinity in horizontal transects of the Strait of Hormuz were analyzed using the ROPME data. Later, data on typical sound speed ...
متن کاملShakedown of unbound granular material
Compacted unbound granular materials are extensively used as sub-layer in pavement design. Most pavement design guides assume that they are responsible for the degradation and deformation of the roads and railways that they support. Biaxial tests are usually employed to investigate the elasto-plastic response of these materials to cyclic loading. A particularly interesting question is whether a...
