Exergetic Analysis of Using Gaseous Fuels in Spark Ignition Engines
(Journal of Thermophysics and Heat Transfer (The American Institute of Aeronautics and Astronautics), 2014)
This paper aims to investigate the use of alternative gaseous fuels in spark ignition engines via an exergy analysis.A quasi-dimensional two-zone thermodynamic cycle model is used for this purpose. The intake and exhaust ...
Formation of skarns at Gümüşhane (Northeastern Turkey)
(Neues Jahrbuch für Mineralogie-Abhandlungen, 2011)
Skarn deposits are located in the NE Black Sea region of Turkey belonging to the Alpin metallogenic province. The Fe skarn deposit at Arnastal is hosted by Late Cretaceous carbonate rocks comprised of limestone and the ...
The Geochemical and Sr-Nd isotopic Characteristics of Murgul (Artvin) Volcanics in the Eastern Black Sea Region (NE Turkey).
(Chemie der Erde/Geochemistry, 2014)
The studied volcanic rocks are footwall and hanging wall dacites from the Murgul mine and the surrounding area. Moreover, the hanging wall dacites contain enclaves. Footwall dacite contains biotite, whereas hanging wall ...
Investigation of Freeze-Thaw Effects on Mechanical Properties of Fibre Reinforced Cement Mortars, (ISI), Volume 58, March 2014, Pages 463-472.
(Composites Part B: Engineering, 2014-03)
Fibers are used for improving some properties of conventional concrete (which is a brittle material) such as tensile strength, abrasion resistance, absorption and crack control. This study investigates the usability of ...
The in situ natural radionuclide (238U,232Th and40K) concentrations in Gümüşhane granitoids: implications for radiological hazard levels of Gümüşhane city, northeast Turkey
(Elsevier, 2019-05-12)
We have carried out 48 in situ measurements on radioactivities of 238U, 232Th and 40K isotopes at the Gümüşhane granitoid plutons employing gamma-ray spectrometer with a NaI(Tl) scintillation detector. The radionuclide ...
Irreversibility Line and Flux Relaxation Bi:2223/Ag tape Prepared by CTFF Technique : H // c axis
(SPRINGER, 233 SPRING ST, NEW YORK, NY 10013 USA, 2010-04-29)
We have studied flux dynamics in Bi:2223/Ag tape prepared by the CTFF technique in the orientation of H//c axis. Irreversibility line (IL) of a Bi:2223/Ag tape has been determined from AC susceptibility and the DC magnetization ...
K-Ar dating, whole-rock and Sr-Nd isotope geochemistry of calc-alkaline volcanic rocks around the Gümüşhane area: implications for post-collisional volcanism in the Eastern Pontides, Northeast Turkey
(Springer-Verlag Wien, 2013-05-14)
Volcanic rocks from the Gümüşhane area in the southern part of the Eastern Pontides (NE Turkey) consist mainly of andesitic lava flows associated with tuffs, and rare basaltic dykes. The K-Ar whole-rock dating of these ...
Kinetic characterization of GES-22 ß-lactamase harboring the M169L clinical mutation
(2016-12)
The class A β-lactamase GES-22 has been identified in Acinetobacter baumannii isolates in Turkey, and subsequently shown to differ from GES-11 by a single substitution (M169L). Because M169 is part of the omega loop, a ...
Magnetic Characterization of SiC Doped Bulk MgB2 Superconductor
(SPRINGER, 233 SPRING ST, NEW YORK, NY 10013 USA, 2011-01)
Flux pinning is a very significant mechanism to improve critical current density in MgB2 for many applications, such as developing the performance of wires and tapes. In this study, we have done a systematic study of SiC ...
The Magnetic and Structural Properties of SiC-Doped MgB2 Bulks Prepared by the Standard Ceramic Processing
(SPRINGER, 233 SPRING ST, NEW YORK, NY 10013 USA, 2011-01)
According to general formula MgB2-x SiC (x) (x=0,0.05,0.1,0.2), MgB2 and SiC-doped bulk superconductors were prepared by the standard ceramic processing. The mixtures of the corresponding powders were sintered at 750 degrees ...
