background: studies show that vestibular rehabilitation is an important option in the treatment bppv that is common in elderly. the purpose of this study was to analyze the effect of epley maneuver on vertigo symptoms in elderly patients with benign paroxysmal positional vertigo. methods: this cross-sectional-analytic study was performed from may 2007 to february 2010 on 67 patients (29 female,...

In this paper, some results are provided for minimum time roll about velocity vector maneuvering with thrust-vectoring and aerodynamic control in effect. The mathematical model for attitude motions of the aircraft is developed. First order necessary conditions for optimality using Pontryagen principle is applied, and the existence of an extreme family of solutions for the maneuver is shown. Mul...

UNLABELLED Benign Paroxysmal Positional Vertigo (BPPV) is a frequent cause of dizziness and despite of the excellent results with its treatment, there is some controversy about management. AIM To assess the efficacy of Epley Maneuver with and without post-maneuver restrictions. STUDY DESIGN Prospective randomized.

When it comes to web search, information retrieval (IR) represents a critical technique as pages have been increasingly growing. However, users face major problems; unrelated user query retrieved documents (i.e., low precision), lack of relevant document recall), acceptable time, and minimum storage space. This paper proposed novel advanced document-indexing method (ADIM) with an integrated evo...

PURPOSE To evaluate a technique for contrast agent preparation as mixing the patients' blood with agitated saline and to compare it with agitated saline alone in diagnosis of cardiac right-to-left shunt in regard to their sensitivity, time window, and distribution of artificially induced microembolic signals. METHODS Fifty-two patients with stroke who had Transesophageal echocardiography prov...
