Detection of causative bodies by normalized full gradient of aeromagnetic anomalies from east Marmara region, NW Turkey

Keskinsezer, Ayhan (ELSEVIER SCIENCE BV, 2008)

There are lithological and structural diversity of rock units underlying the East Marmara region, NW Turkey. The 3-D NFG method has been applied to aeromagnetic data in the study area. We have also used the Euler deconvolution ...
Direct alkaline leaching of mechanically activated diasporic bauxite

Yıldız, Kenan; Alp, Ahmet (SOC MINING METALLURGY EXPLORATION INC, 2009)

Diasporic bauxite from the Mugla-Milas region was mechanically activated in a planetary mill for different activation times and the structural changes were examined by X-ray diffraction analysis (XRD), scanning electron ...
Dissolution kinetics of primary chalcopyrite ore in hypochlorite solution

Gülfen, Mustafa; Aydın, Ali Osman (PERGAMON-ELSEVIER SCIENCE LTD, 2006)

Dissolution kinetics of primary chalcopyrite ore from Artvin-Murgul, Turkey has been studied in hypochlorite solution. The dissolution kinetics was found to be controlled by diffusion through the product layer as the ...
Effect of Al and Ti on High-Temperature Oxidation Behavior of CoCrFeNi-Based High-Entropy Alloys

Azmi Erdogan; Kadir Mert Doleker; Zeytin, Sakin (SPRINGER, 2019)

CoCrFeNiAlxTiy high-entropy alloys were produced by the induction melting method and their oxidation behavior investigated when exposed to 1000 degrees C for different durations. One or more body-centered cubic phases were ...
Environmental Effects and Importance of the Risk Assessments for Mining Wastewater

Çelebi, Ahmet; Özdemir, Serdar; M Gulsunkilic; O Onel; H Basarir; M Karadeniz; E Torunbilgic (TMMOB MADEN MUHENDISLERI ODASI, 2015)

Every scale of mining activities have huge impact to environment. Monitoring and assessing of the size of the effect and take measure is vital. In this present study risk assessment studies in mining areas and their effect ...
Estimation of seismic quality factor: Artificial neural networks and current approaches

Yıldırım, Eray; Saatçılar, Ruhi; Semih Ergintav (ELSEVIER SCIENCE BV, 2017)

The aims of this study are to estimate soil attenuation using alternatives to traditional methods, to compare results of using these methods, and to examine soil properties using the estimated results. The performances of ...
Selective extraction of nickel from ammoniacal solutions containing nickel and cobalt by emulsion liquid membrane using 5,7-dibromo-8-hydroxyquinoline (DBHQ) as extractant

Kumbasar, Recep Ali (PERGAMON-ELSEVIER SCIENCE LTD, 2009)

The selective extraction and concentration of nickel from ammoniacal solutions containing nickel and cobalt by an emulsion liquid membrane (ELM) technique using 5,7-dibromo-8-hydroxyquinoline (DBHQ) as extractant has been ...
Time-lapse electrical resistivity tomography (ERT) monitoring of used engine oil contamination in laboratory setting

Nazifi, Hafiz Mohammed; Gulen, Levent; Gurbuz, Ertugrul; Peksen, Ertan (2022)

Geophysical methods are being used effectively for monitoring, characterizing, and mapping Light Non-Aqueous Phase Liquids (LNAPLs). Although Used Engine Oil (UEO) is one of the most common LNAPLs contaminants within the ...
Tribology Study of Pulse Electrodeposited Ni-B-SWCNT Composite Coating

Dogan, Fatih; Duru, Erhan; Uysal, Mehmet; Akbulut, Hatem; Aslan, Serdar (2022)

The wear resistance performance of Ni-B-single-walled carbon nanotube (SWCNT) composite coatings produced by impact electrodeposition on a mild steel substrate has been investigated. After electrodeposition, all samples ...
