A theoretical study of the nonlinear propagation of picosecond chirped pulses in single-mode fibers is presented. We show that, under appropriate conditions, spectral narrowing-rather than broadening, as is generally believed-is induced, owing to the interplay of self-phase-modulation and dispersion. For downchirped pulses at a wavelength of 0.9 microm and(More)
BACKGROUND Palm kernel cake is a biodiesel byproduct and an alternative feed additive in cattle production. This study evaluated the effects of palm kernel cake added to bulls' diets on the physicochemical and sensory characteristics of their meat. Thirty-two young Nellore bulls were used, distributed in a randomized experimental design with four(More)
