This research had conducted to investigate light intensity effects on the lucky bamboo growth in Islamic Azad University, Abhar Branch. The experiment arranged as a complete randomized block design with five treatments (0.75, 1.14, 1.89, 2.29 and 4.09 mmol m-2 s-1) in ten replications. Results showed that 1.89 mmol m-2 s-1 had significant differences than other treatments. The higher level of r...

Introduction: Functional Near-Infrared Spectroscopy (fNIRS) is an imaging method in which light source and detector are installed on the head; consequently, re-emission of light from human skin contains information about cerebral hemodynamic alteration. The spatial probability distribution profile of photons penetrating tissue at a source spot, scattering into the tissue, and being released at ...

Radiation propagating over cosmological distances can probe light weakly interacting pseudoscalar (or scalar) particles. The existence of a spin-0 field changes the dynamical symmetries of electrodynamics. It predicts spontaneous generation of polarization of electromagnetic waves due to mode mixing in the presence of background magnetic field. We illustrate this by calculations of propagation ...
