Introduction: In recent years tend to use of natural fibers has increased in making sound absorbers. Fiber-based natural materials have low density, low production costs, and are biodegradable. Material and Methods: In this study, the effect of nanoclay and the behavior of the nanocomposite specimens containing tea waste, polypropylene, and nanoclay in the sound absorption coefficient are inve...
Single unit recording has been used as a well-known technique to study the electrical behavior of neurons. In this respect, the classical methods are rather expensive. In this study a simple and inexpensive method for single unit recording studies has been introduced. Computer sound card was used for data acquisition. Neural responses were saved via simple sound applicable packages and then ana...
This paper reviews the citizen media and studies the fourth generation of communication development theories emphasizes on participatory communication. In this kind of theories the cibizen’s parbicipation and their activeness is the center of case instead of the public Accessibility of media. Therefore providing an opportunity for dialogue through media and providing dialogue Democracy in ...
Aquatic ecosystems are heterogeneous in terms of light and sound distribution. The aim of this study was to investigate the effect of environmental abiotic factors, light and sound stimuli, on Daphnia (Daphnia magna) swimming behaviour. Here, we examined behavioural changes of Daphnia (N=24) in response to light and sound treatments simultaneously. The treatments concerned a 2×2 design with br...
nowadays, previously performance-oriented architecture of healthcare centers has been switched to creating a healing environment; and one of the most important pillars to create such an environment is omitting sound pollutions. today's hospital have chaotic situation regarding noise pollution not only in our country, but also in all over the world. the present study aims to provide a compl...
Introduction: Radiotherapy is still one of the main options for cancer treatment but it is in association with damage to normal cells as well as the tumor cells. To reduce the injury in normal cells we have evaluated the effect of 528 hertz sound after X irradiation in peripheral blood lymphocytes. Materials and Methods: in this study, peripheral blood was o...
