Use of methacrylic acid grafted poly(ethylene terephthalate) fibers for the removal of basic dyes from aqueous solutions
(John Wiley & Sons Inc, 2008)
A reactive fibrous adsorbent was prepared through the grafting of a methacrylic acid monomer Onto poly(ethylene terephthalate) fibers for the removal of basic dyes such as methylene blue and basic red 9 from aqueous solutions ...
Dermal vacuoles in two biopsies of psoriasis
(Wiley-Blackwell, 2008)
Two patients presented with cutaneous lesions clinically typical of psoriasis. The first case was a 38-year-old man and the second was a 51-year-old woman. To confirm the diagnosis, 4-mm punch biopsy samples were obtained ...
Orthodontic extrusion of a traumatically intruded permanent incisor: a case report with a 5-year follow up
(Blackwell Publishing, 2008)
This report presents a case of intrusive luxation of the immature left maxillary central incisor in an 8-year-old girl. Initially, it was decided to allow the intruded tooth to spontaneous re-erupt because it had open ...
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 ...
The effects of zinc nitrate, zinc acetate and zinc chloride precursors on investigation of structural and optical properties of ZnO thin films
(Elsevier Science Sa, 2008)
ZnO thin films were prepared using zinc chloride, zinc acetate and zinc nitrate precursors by spray pyrolysis technique oil glass substrates at 550 degrees C. Structural and optical properties of ZnO films were investigated ...
