Non-modal phonation conveys both linguistic and paralinguistic information, and is distinguished by acoustic source and filter features. Detecting non-modal phonation in speech requires reliable F0 analysis, a problem for telephone-band speech, where F0 analysis frequently fails. We demonstrate an approach to the detection of creaky phonation in telephone speech based on robust F0 and spectral ...

BACKGROUND & OBJECTIVES To evaluate the retention of complete cast crowns in teeth with adequate and inadequate crown height and to evaluate the effects of auxiliary retentive features on retention form complete cast crowns. MATERIALS AND METHODS Sixty freshly extracted human premolars. They were divided into 2 major groups depending upon the height of the teeth after the preparation. Group1 ...

To study the anti-inflammatory activity of a hydro-ethanolic extract of Alternathera brasiliana leaves (HEAB).The study was carried out using Wistar albino rats (150-180 gm) and Swiss albino mice (20-25 gm) of either sex. HEAB was prepared by cold maceration. The effect of HEAB was investigated for anti-inflammatory activity using carrageenan induced paw edema (acute), cotton pellet granuloma (...

The purpose of this study was to determine the fracture resistance of 4 post and core systems. 40 extracted maxillary canines (for orthodontic reason) were used for this study. The samples were divided into 4 groups, which were: Group (1) Cast post luted with Rely X ARC; Group (2) Cast post cemented with zinc phosphate; Group (3) Fibre post luted with Rely X + Filtek Z-250 as core material; Gro...

Received: 27 April 2013 Accepted: 6 August 2013 Abstract Background and Aim: Discoloration is among the most common problems of composite restorations. Color change over time compromises the main advantage of composite resins namely their high esthetics. In such cases, the restoration needs to be replaced. .The aim of this in-vitro study was to evaluate the effect of accelerated artificial agin...

Correspondence analysis (CA) is a statistical method that is widely used in multiple disciplines to reveal relationships amongst variables. Among others, CA has been successfully applied for microarray data analysis. One of CA’s strengths is its ability to help visualize the complex relationships that may be present in the data. In this sense, CA is a powerful exploratory tool that takes advant...

Background: Diazinon (DZN) is an organophosphate insecticide which is used worldwide in agriculture. The exposure to this chemical might lead to damages to the living systems.
