K-Ar dating, whole-rock and Sr-Nd isotope geochemistry of calc-alkaline volcanic rocks around the GumuAYhane area: implications for post-collisional volcanism in the Eastern Pontides, Northeast Turkey
(Springer Wien, 2014)
Volcanic rocks from the GumuAYhane 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 ...
Petrogenesis of the late Cretaceous Turnagol intrusion in the eastern Pontides: Implications for magma genesis in the arc setting
(China Univ Geosciences, Beijing, 2013)
A series of Cretaceous plutons is present in the eastern Pontides of northeastern Turkey. The Turnagol intrusion is the least studied and, thus, the least understood plutons in the orogen. This intrusion consists of ...
Investigation of radiation absorption coefficients of lead-zinc mine waste rock mixed heavy concrete at 662-1460 keV energy range
(Elsevier Sci Ltd, 2018)
The objective of this study is to observe the radiation shielding efficiency of concrete produced by using the lead wastes that are stored in lead-zinc mines processing of which is not financially viable in the mines they ...
The Performance of Alternative Refrigerant Gas R152a as Mobile Air Conditioning Refrigerant
(Aidic Servizi Srl, 2014)
In this study, the possible alternative replacement of R134a with R152 in the air conditioning (AC) system of an automobile has been investigated theoretically. The properties of the R152a is presented and compared with ...
Single production of the excited electrons in the future FCC-based lepton-hadron colliders
(World Scientific Publ Co Pte Ltd, 2018)
We study the composite electron production at the FCC-based three electron-proton colliders with the center-of-mass energies of 3.46, 10 and 31.6 TeV. For the signal process of ep -> e* X -> e gamma X, the production ...
Utilization of granulated marble wastes and waste bricks as mineral admixture in cemented paste backfill of sulphide-rich tailings
(Elsevier Sci Ltd, 2015)
This study presents the utilisation of granulated marble wastes (MW) as an additive (10-30 wt%) and waste bricks (WB) as replacement and additive (15-45 wt%) to ordinary Portland cement (OPC) for cemented paste backfill ...
Nature of tourmaline formation in quartz porphyry in the E Sakarya zone (NE Turkey): geochemistry and isotopic approach
(Edizioni Nuova Cultura, 2019)
Tourmaline, which exhibits important differences in terms of texture and composition, is found in 44 My aged quartz porphyry from Karadag in the eastern Pontide (NE Turkey). Tourmaline has high Al and Mg contents and is ...
Power Spectrum Analysis of EEG for Watching 2D & 3D Videos and Resting State
(IEEE, 2018)
Analysis of the brain waves has become useful over than 80 years. Along with the medical application, the brain signal is also used for other research works in the last fifteen years. In this study, by considering the depth ...
Determining Complexity within the Crowd Movements
(IEEE, 2018)
The segmentation of the moving and non-moving parts in an image within the crowd analysis studies is a crucial result in terms of understanding the behaviour. However, in many studies carried out, moving areas are assessed ...
Improvement of Coercivity and Curie Temperature of Sintered Nd-Fe-B Permanent Magnets by Addition of Cu and Ni
(Springer, 2014)
Sintered Nd-Fe-B magnets are some of the strongest magnetic materials showing magnetic properties. Blending addition is frequently performed in order to improve the magnetic properties of these materials. In this work, ...
