Wear behavior of different surface treated cam spindles
(ELSEVIER SCIENCE SA, 2006)
In this study wear behavior of cam spindles made of five different surface treated nodular cast iron (GGG50) and induction hardened CK45 steels was investigated. In the experiments; PVD-TiN-coated, both borided and ...
Posterior epidural migration of sequestered lumbar disc fragment causing cauda equina syndrome
(TAYLOR & FRANCIS LTD, 2005)
Posterior epidural migration of free disc fragments is rare, and posterior migration of the free fragments causing cauda equina syndrome is exceptionally rare. This report describes a 53-year-old man with disc fragment ...
Two-liquid flotation of sulphides: An electrochemical approach
(PERGAMON-ELSEVIER SCIENCE LTD, 2007)
The roles of pulp potential, collector and depressants on the flotation of pyrite, chalcopyrite and galena were studied by using two-liquid flotation technique. The potential was adjusted by reducing (Na2S and Na2S2O4) and ...
Apatite fission track data from central Anatolian granitoids (Turkey): Constraints on Neo-Tethyan closure
(AMER GEOPHYSICAL UNION, 2007)
[1] Apatite fission track age versus elevation profiles and temperature-time-path modeling indicate an early to middle Paleocene ( 57 - 62 Ma) rapid exhumation of the Middle to Late Cretaceous granitoids in central Anatolia ...
Fine dry grinding of zeolite in a laboratory ball mill
(WILEY-V C H VERLAG GMBH, 2003)
This paper presents the importance and usage of natural zeolites, which was recently recognized in the industry. Therefore, the grinding properties of natural zeolite were studied with the emphasis on a kinetic study in a ...

Objectives: The aim of this cross-sectional study was to identify the infant feeding practices and to evaluate the attitudes and beliefs of mothers on breast-feeding in Turkey. Methods: This study was established in 10 ...
Force constant calculations for octahedral complexes of the type M(CO)(5)L, based on the CO-factored force field
(ELSEVIER SCIENCE SA, 2001)
Using the maximum value of the sum of the interaction constants, the CO-factored force field of octahedral M(CO)(5)L molecules was solved to give the relations which allow direct calculation of force constants from C-O ...
Swelling characterization of gamma-radiation induced crosslinked acrylamide/maleic acid hydrogels in urea solutions
(ELSEVIER SCI LTD, 2006)
Swelling behaviors of crosslinked acrylamide/maleic acid (CAMA) hydrogels synthesized by gamma-radiation crosslinking of acrylamide and maleic acid in aqueous urea solutions were investigated. CAMA hydrogels containing ...
Evaluation of cerebral vasospasm with transcranial magnetic stimulation: an experimental study
(SPRINGER-VERLAG, 2001)
Despite the current use of several different methods for diagnosis and follow-up of cerebral vasospasm after subarachnoid hemorrhage, an easy, quick, reliable, and noninvasive method is still needed for evaluation of this ...
