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 ...
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 ...
Kapalı Kare Ortamlarda Periyodik Olarak Değişen Sıcaklığa Sahip Duvara Konulan Engelin Doğal Taşınım ile Isı Transferi Üzerine Etkilerinin Sayısal İncelenmesi
(6th International Advanced Technologies Symposium, 2011-05-16)
Natural convection heat transfer in square enclosures having a horizontally positioned obstacle on one of the vertical wall is numerically investigated. The obstacle included wall has periodically varying temperature profile ...
LA-ICP MS zircon dating, whole-rock and Sr–Nd–Pb–O isotope geochemistry of the Camiboğazı pluton, Eastern Pontides, NE Turkey: Implications for lithospheric mantle and lower crustal sources in arc-related I-type magmatism
(Elsevier B.V. All rights reserved, 2014-02-15)
Late Cretaceous I-type plutons arewidespread in the Eastern Pontides,NE Turkey. The studied Camiboğazı pluton is a composite pluton consisting of diorite, tonalite, monzodiorite, monzonite, quartz monzonite, granite, and ...
Levitation force at different temperatures and superconducting properties of nano-structured MgB2 superconductors
(ELSEVIER SCIENCE SA, PO BOX 564, 1001 LAUSANNE, SWITZERLAND, 2010-03-04)
The levitation and pinning force properties of nanocrystalline MgB2 superconductors prepared by a mechanical alloying technique with varying milling duration have been investigated. Levitation force measurements under ...
Magnetic Properties of YBCO Single-Crystal Grown on Y2O3 Layer by a Cold Top-Seeding Method
(SPRINGER, 233 SPRING ST, NEW YORK, NY 10013 USA, 2012-02)
In this work, single-crystal samples 20 mm in diameter were grown by a cold top-seeding method. In order to study the effect of an Y2O3 buffer layer, a compacted precursor was located in a crucible on a buffer layer of ...
