Abstract: Cannabinoid derivatives are known for their function in the central as well as peripheral nervous system. Disclosed are some novel (+)-cannabidiol (CBD) derivatives of the general formula (I) having selective activity in the peripheral, but not in the central nervous system. Use of (+)-CBD derivatives as analgesics, anti-inflammatory and anti-diarrheal agents is also disclosed.

Abstract: Method and system for determining the optical temporal response of a medium (12) to a short optical pulse excitation, by sending light (11) that comprises spectral frequencies which make up the Fourier Transform of the short pulse to be emulated through the medium. The relative amplitude and phase change (20) of each of the spectral components light (14) exiting the medium is determined with respect to that of the illuminating light source and the spectral response of the medium is obtained from the relative amplitude and phase change. An inverse Fourier Transform is then computationally performed on the spectral response to obtain the temporal response of the medium to the emulated short pulse.
