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 ...

(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 ...
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 ...
Experimental investigation of cutting tool performance in high speed cutting of hardened X210 Cr12 cold-work tool steel (62 HRC)
(Elsevier Ltd, 2005)
This study explored the performance and wear behaviour of different cutting tools in end milling of X210 Cr12 cold-work tool steel hardened to 62 HRC. The purpose of the experiments reported in this paper is to investigate ...

Ditrichum pusillum (Hedw.) Hampe has been collected for the first time from the Western Black Sea region of Turkey. A description of the species is given, along with notes on the ecology and a discussion of the phytogeographic ...
Statistical analysis of fracture strength of composite materials using Weibull distribution
(2002)
In this study, the fracture strength of a carbon-epoxy composite plate has been statistically analysed by Weibull distribution. Nineteen tension tests were carried out. The results obtained vary between 439 MPa and 552 ...
Some taxonomic features of Taphozous nudiventris Cretzschmar, 1830 vel 1831 from Turkey (Chiroptera: Emballonuridae)
(2007)
This study was based on the records of baculum features, hair scale form, and karyotype of Taphozous nudiventris magnus. The baculum is a distinctive feature in separating this subspecies from T. n. kachhensis. The structure ...
An analysis of the realization rate of affective objectives of science and technology curriculum
(2009)
By the help of science education not only cognitive learning but affective learning is also contributed. To be able to gain the qualities in a field, an individual should be interested in that field, consider that field ...
The relationship between serum sex steroid levels and heart rate variability parameters in males and the effect of age
(2010)
Objectives: We evaluated the relationships between sex steroid levels and heart rate variability (HRV) parameters. Study design: The study included 114 male subjects (mean age 46.6±11.3 years) presenting to our department ...
