the kasian volcanic body is located in the eastern margin of the zagros thrust belt, close to the sanandaj-sirjan metamorphic zone. these volcanic rocks are mainly composed of andesite and andesite-basalt rocks with porphyritic, hypocrystalline porphyritic, hyalo-porphyritic and hyalo-microlitic porphyritic textures. analyses of the distributions of major, rare earth and trace elements reveal a...

Research has shown that if two frequencies differing in 30Hz or less are presented in each ear, the brain will process these frequencies as an entirely separate third tone. This third frequency, or binaural beat, can stimulate production of brain waves if created in the correct frequency range. This study recruited 38 participants to determine if binaural beats in the beta range can increase at...
