study the effects of low level laser diode on no production and healing of diabetic and cortisone acetate and normal wounded sd rats

nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...

The formant patterns of fricative consonants

Analysis and synthesis of fricative consonants

This thesis studies and interprets the -entory of acoustic events associated with the changing vocal-tract configurations .:at characterize fricatives preceding vowels. Theoretical considerations of the articulatory, aerodynamic and acoustic aspects of the production of fricatives provide the foundation for interpreting the acoustic data. Fricative characteristics are considered with respect to...
