Computerized Analysis of Acoustic Characteristics of Patients with Internal Nasal Valve Collapse Before and After Functional Rhinoplasty.

Acoustic analysis of sounds produced during speech provides significant information about the physiology of larynx and vocal tract. The analysis of voice power spectrum is a fundamental sensitive method of acoustic assessment that provides valuable information about the voice source and characteristics of vocal tract resonance cavities. The changes in long-term average spectrum (LTAS) spectral tilt and harmony to noise ratio (HNR) were analyzed to assess the voice quality before and after functional rhinoplasty in patients with internal nasal valve collapse.

Determination of the trophic situation in Gheshlagh reservoir (North-Western Iran).

'Trophic state' is often used to classify aquatic ecosystems according to biotic productivity. Carlson trophic state indices were used to assess the trophic situation in Gheshlagh reservoir (North-Western Iran), on which a dam was constructed three decades ago. Using data from a one-year surface sampling, a comparison of the trophic state index (TSI), between four sampling points in the reservoir and one sampling point under the dam, was performed.
