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 ...
Designing of a powder compressing device with vibration and investigation of compressibility of MgO powders with this device
(Elsevier Sci Ltd, 2007)
One of metal matrix composite (MMC) production methods is infiltration of liquid metal into preformed reinforcement. In this method, MMCs are produced by infiltration of liquid metal into preformed reinforcement using one ...

Cystocaulus ocreatus infection in Anatolian wild sheep and dwarf goats
(Scientific Technical Research Council Turkey-Tubitak, 2007)
An Anatolian wild sheep (Ovis orientalis anatolica) from a wild ruminant farm near Kirikkale, Turkey, was necropsied. Parasitic nodules were situated beneath the pleura of the caudodorsal lobes of the lungs. First stage ...
Chemoenzymatic synthesis of 2-brorno-6-hydroxy-3-methoxy-2-cyclohexen-1-one
(Scientific Technical Research Council Turkey-Tubitak, 2007)
A chemoenzymatic synthesis of 2-bromo-6-hydroxy-3-methoxy-2-cyclohexen-1-one starting from cyclohexane-1,3-dione is reported. Manganese (III) acetate-mediated acetoxylation followed by the enzyme-mediated hydrolysis of ...
Is Cervicotomy Enough for Removal of Retrosternal Goiters?
(Tubitak Scientific & Technical Research Council Turkey, 2008)
Aim: The aim of this study was to evaluate the surgical approaches in retrosternal goiters. Materials and Methods: We reviewed 23 patients operated with the diagnosis of retrosternal goiter. Twelve (52%) of the cases were ...
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 ...
Adsorption of hexavalent chromium from aqueous solutions using 4-vinyl pyridine grafted poly(ethylene terephthalate) fibers
(Springer, 2005)
Sorption of hexavalent chromium ions from aqueous solution by 4- vinyl pyridine (4-VP) grafted poly(ethylene terephthalate) (PET) fibers was studied. The Influences of adsorption time, pH of solution and Cr(VI) concentration ...
The effect of ischemia reperfusion on intestinal contractility regulated by the nitrergic system
(Scientific Technical Research Council Turkey, 2004)
Because of the interaction between nitric oxide (NO) and the superoxide anion radical, the effect of ischemia-reperfusion on intestinal contractility regulated by the nitrergic system was investigated in the present study. ...
