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 ...
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, ...
Dimethyl Sulfoxide Extract of Dianthus carmelitarum Induces S Phase Arrest and Apoptosis in Human Colon Cancer Cells
(Routledge Journals, Taylor & Francis Ltd, 2019)
Although several studies have investigated the cytotoxic effects of different Dianthus species, there has been only limited research into the cytotoxic effect of Dianthus carmelitarum. The purpose of this research was to ...
Stereo-based palmprint recognition in various 3D postures
(Pergamon-Elsevier Science Ltd, 2017)
In order to increase performance in palmprint recognition systems, various devices are normally used to restrict the movement of the hand. These can cause problems, especially for those users with physical disabilities. ...
Modelling and mapping third dimension in a spatial database
(Taylor & Francis Ltd, 2011)
In this paper, an overview of phases for modelling and mapping third dimension of spatial objects in a database is presented based on a selected spatial database management system (DBMS). These phases include (1) defining ...
