introduction :mucositis is a disturbing side effect of radiotherapy treatment for head and neck cancer. to date, no effective modality for its prophylaxis and treatment has been found. we performed this study to evaluate the efficacy of oral zinc sulphate in delaying the onset of oral and pharyngeal mucositis and decreasing their severity. materials and methods : a total of 58 patients who were...

introduction: controversy remains as to the advantages and disadvantages of pharyngeal packing during septorhinoplasty. our study investigated the effect of pharyngeal packing on postoperative nausea and vomiting and sore throat following this type of surgery or septorhinoplasty.   materials and methods: this clinical trial was performed on 90 american society of anesthesiologists (asa) i or ii...

The X-ray microbeam method for measurement of articulatory dynamics has been used to acquire large amounts of data, with reduced X-ray dosage, resulting in one of the most widely used freely available speech production databases. The Xray Microbeam Speech Production Database (XRMB-SPD), developed at Wisconsin University, USA, includes a vast amount of coordinate data describing articulatory mov...

para-veterinarians are professionals in having a liaise between veterinary doctors and livestock owners beside their ability to achieve some of the veterinarians activity such as collecting information about sick animals, using thermometer, using needles and syringes, calculating, diluting and using antiseptic, knowledge about live and inactive vaccines, oral treatment of animals, herbal medici...

1. Para-f -structures. The notion of a para-f -structure on a differentiable manifold was introduced and studied in [2]. Let M be an n-dimensional differentiable manifold of class C∞. The set of all vector fields on M will be denoted by χ(M) and the tangent space of M at a point m∈M by TmM . Definition 1.1. Let M be an n-dimensional differentiable manifold. If φ is an endomorphism field of cons...

The vowel space reflects the right-angled shape of the vocal tract, and many consonants exploit the palatal wall. These two facts suggest the importance of the geometry of peripheral structure in speech production. In this study, the relationship between geometry and articulatory variation was examined using a database of English and Japanese speakers. The geometry of each speaker's vocal tract...
