introduction: the basic objective of this study is to investigate the effects of alpha and theta brain waves amplitude increase in occipital area on reducing the severity of symptoms of generalized anxiety disorder and to increase the global functioning level in patients with gad. methods: this study is a quasi-experimental study with pre-test and post-test with two groups. for this purpose, 28...

Sound propagation in water-saturated granular sediments is known to depend on the sediment porosity, but few data in the literature address both the frequency and porosity dependency. To begin to address this deficiency, a fluidized bed technique was used to control the porosity of an artificial sediment composed of glass spheres of 265 μm diameter. Time-of-flight measurements and the Fourier p...

The study of granular matter is of interest for fundamental physics as well as for technological applications. The intensive studies of liquids and solids gave physicists powerful tools for investigating these states of matter. These tools are, however, very difficult to apply to granular matter @1#. Little work has been done on sound propagation in real granular media. Experiments have been pe...

Even if air and other gases appear to be quite compressible in our daily doings, we have until now only analyzed incompressible flow and sometimes applied it to gases. The reason is— as pointed out before—that a gas in steady flow “prefers to get out of the way” rather than become compressed when it encounters an obstacle. Unless one entraps the gas, for example in a balloon or bicycle tire, it...

The mining chute is an important equipment in the process of coal transportation and coal screening preparation. During the working process, the mining chute will generate a lot of vibration and noise because of constantly friction and impact of gangue and coal blocks. In order to reduce the vibration and noise during the operation of the chute, a new type of foam aluminum laminated structure i...

objective(s) bupropion is an atypical antidepressant that is widely used in smoke cessation under fda approval. the study of synaptic effects of bupropion can help to finding out its mechanism(s) for stopping nicotine dependence. in this study the effects of perinatal bupropion on the population spike (ps) amplitude of neonates were investigated. materials and methods hippocampal slices were pr...

telemedicine has changed the way of health care. it is an indispensable tool in the hands of doctors to accelerate and facilitate the process of data interchange. wireless networks consist of small nodes with communications capabilities. development of wireless networks of telemedicine system is highly demanded since these networks promise a wide range of potential applications. in this paper t...

A model for the acoustic production of gravitational waves at a first-order phase transition is presented. The source of gravitational radiation is the sound waves generated by the explosive growth of bubbles of the stable phase. The model assumes that the sound waves are linear and that their power spectrum is determined by the characteristic form of the sound shell around the expanding bubble...

Evaluation of the cardiovascular system of canine pediatrics requires awareness of the anatomical and physiological changes occurring from birth to six months of age. The aim of this study was to report electrocardiographic changes in the littermate mongrel dogs from birth tosix months. Serial six-lead electrocardiograms were recorded from ten normal littermate mongrel dogs kept on right latera...
