A fixed point theorem for multi-maps satisfying an implicit relation on metric spaces
(Univ Belgrade, Fac Electrical Engineering, 2008)
We present a fixed point theorem for multi-valued mapping satisfying an implicit relation on metric spaces.
Position vectors of a timelike and a null helix in Minkowski 3-space
(Pergamon-Elsevier Science Ltd, 2008)
In this paper, we study the position vectors of a timelike and a null helix (or a W-curve), i.e. curve with constant curvatures in the Minkowski 3-space E-1(3). We give some characterizations for timelike and null helix ...
Design optimization of cutting parameters when turning hardened AISI 4140 steel (63 HRC) with Al2O3+TiCN mixed ceramic tool
(Elsevier Sci Ltd, 2007)
Due to their high hardness and wear resistance, Al2O3-based ceramics are one of the most suitable cutting tool materials for machining hardened steels. However, their high degree of brittleness usually leads to inconsistent ...
Determination of residual stresses based on heat treatment conditions and densities on a hybrid (FLN2-4405) powder metallurgy steel using artificial neural network
(Elsevier Sci Ltd, 2007)
This paper presents a new approach based on artificial neural networks (ANNs) to determine the residual stresses in PM steel based nickel (FLN2-4405). This study consists of two cases: (i) The experimental analysis: The ...
Effect of chronic diseases and associated psychological distress on health-related quality of life
(Wiley, 2007)
Background: The purpose of this study was to clarify the correlations between the presence of comorbidities and psychological distress and health-related quality of life (HRQL). This was a population-based cross-sectional ...
Synthesis and characterization of spray pyrolysis Zinc Oxide microrods
(Elsevier Science Sa, 2007)
Zinc Oxide (ZnO) microrods were prepared by ultrasonic spray pyrolysis technique on glass substrates. The X-ray diffraction (XRD) patterns and scanning electron microscope images show that obtained rods are composed of ...
Comparison of 2 distalization systems supported by intraosseous screws
(Mosby-Elsevier, 2007)
Introduction: The aim of this study was to compare the effects of 2 distalization systems supported by intraosseous screws for maxillary molar distalization. Methods: Forty subjects with skeletal Class I dental Class II ...

Intratympanic methylprednisolone for sudden sensorineural hearing loss
(Lippincott Williams & Wilkins, 2007)
Objective: Corticosteroids are commonly used for the treatment of sudden sensorineural hearing loss (SSHL). In this study, the effectiveness of intratympanic (IT) corticosteroid injection was studied and compared with a ...
