The influence of nitridation time on the structural properties of GaN grown on Si (111) substrate
(Springer Heidelberg, 2009)In the present paper, the effect of in-situ substrate nitridation time on crystalline quality of GaN films grown on Si (111) substrates by metal organic chemical vapor deposition (MOCVD) were investigated. A thin buffer ... -
Miocene lacustrine succession of the Hoyran Lake Basin, Isparta, southwest Turkey
(Polska Akad Nauk, Polish Acad Sciences, Univ Warsaw, Geology Dept, 2009)The Hoyran Lake Basin is an example of a Neogene rift basin in southwest Turkey.

Enhancement of flotation performance of oil shale cleaning by ultrasonic treatment
(Elsevier, 2009)In this study, it was attempted to enhance the performance of flotation cleaning of oil shales by use of ultrasound. The use of an excitation effect through ultrasonication was investigated towards inorganic particles that ... -
Chemical injection to prevent building damage induced by ground water drainage from shallow tunnels
(Pergamon-Elsevier Science Ltd, 2009)Progressive developments in the application of chemical injection have been acquired through out the centuries, starting from the ancient Romans. The method of silica based injection has been employed for a long time and ... -
Magmatism in the southeastern Anatolian orogenic belt: transition from arc to post-collisional setting in an evolving orogen
(Geological Soc Publishing House, 2010)Late Cretaceous to Middle Eocene calc-alkaline to alkaline magmatic rocks emplaced within the southeastern Anatolian orogenic belt, the most extensive magmatic belt in Turkey, result from the complex collision between the ... -
Predicting the relationships between brittleness and mechanical properties (UCS, TS and SH) of rocks
(Academic Journals, 2010)This paper presents the evaluation of uniaxial compressive strength (UCS) predicted from Shore hardness (SH) tests and to correlate brittleness concepts, which are derived from UCS, tensile strength (TS) and Shore hardness ... -
Hydraulic Head Interpolation in an Aquifer Unit Using ANFIS and Ordinary Kriging
(Springer-Verlag Berlin, 2011)In this study, Ordinary Kriging (OK), and Adaptive Neuro Fuzzy based Inference System (ANFIS) are evaluated for assessing hydraulic head distribution in an aquifer unit covering 40 km(2). Cartesian coordinates of the samples ... -
U-Pb and Ar-40-Ar-39 Geochronology and Isotopic Constraints on the Genesis of Copper-Gold-Bearing Iron Oxide Deposits in the Hasancelebi District, Eastern Turkey
(Soc Economic Geologists, Inc, 2011)The Hasancelebi deposit in eastern Turkey, with proven reserves of 95 million metric tons, is a copper-gold-bearing iron oxide deposit. It is chiefly hosted by rocks that underwent widespread sodic-calcic and potassic ... -

Corrosion of magnesium alloy AZ31 screws is dependent on the implantation site
(Elsevier Science Bv, 2011)The corrosion of biodegradable materials is a crucial issue in implant development. Among other materials, magnesium and magnesium based alloys are one of the most promising candidates. Since the corrosion of biodegradable ... -
Dual tree complex wavelet transform based denoising of optical microscopy images
(Optical Soc Amer, 2012)Photon shot noise is the main noise source of optical microscopy images and can be modeled by a Poisson process. Several discrete wavelet transform based methods have been proposed in the literature for denoising images ... -
Recreating a Large-Scale BGP Incident in a Realistic Environment
(Springer, 2013)The Internet has become a critical asset for both the economy and the society. Realistic experimentation environments are needed to study and improve the resilience and the stability of the Internet. In this paper, we ... -
Late Cretaceous to Middle Eocene Magmatism and Metallogeny of a Portion of the Southeastern Anatolian Orogenic Belt, East-Central Turkey
(Soc Economic Geologists, Inc, 2013)Rapidly changing ore deposit types in the Late Cretaceous and early Tertiary in the Southeastern Anatolian orogenic belt in east-central Turkey, from Baskil on the south to Divrigi on the north, broadly reflect shifting ... -
Mechanical characterization of highly porous beta-Si3N4 ceramics fabricated via partial sintering & starch addition
(Elsevier Sci Ltd, 2013)In this study, porous beta-Si3N4 ceramics containing limited amount of Sm2O3 and CaO as sintering aids were produced by addition of potato starch (10 and 20 vol.%) and partial sintering. Two different Si3N4 powders, alpha- ... -
Effects of laser ablated silver nanoparticles on Lemna minor
(Pergamon-Elsevier Science Ltd, 2014)The present study investigates and models the effect of laser ablated silver nanoparticles (AgNPs) on the development of the aquatic macrophyte Lemna minor. Toxic effects of five different AgNP concentrations (8, 16, 32, ... -
Investigation of the failure mechanism and stabilization of a landslide in weathered tuffite, Giresun, northeastern Turkey
(Springer, 2014)This study investigates the causes and failure mechanism of the Aksu landslide that occurred during the construction of the Giresun-Espiye road between KM: 1 + 030-1 + 170 in northern Turkey and recommends proper stabilization ... -
Studies on increasing the performance of chain saw machines for mechanical excavation of marbles and natural stones
(Pergamon-Elsevier Science Ltd, 2014)Slow cutting rate, tool wear and shallow depth of cuts are important practical issues observed with the commercially available chain saw machines. This paper is concerned with increasing the performance of current chain ... -
In silico analysis of autoimmune diseases and genetic relationships to vaccination against infectious diseases
(Bmc, 2014)Background: Near universal administration of vaccines mandates intense pharmacovigilance for vaccine safety and a stringently low tolerance for adverse events. Reports of autoimmune diseases (AID) following vaccination ... -
Utilizing Infrared technologies as a non-destructive evaluation for maintenance of concrete structures
(Crc Press-Taylor & Francis Group, 2015)The aging of road infrastructure is becoming a serious problem worldwide. Although the number of aged structures is increasing rapidly, inspection and maintenance for them cannot catch up with the speed due to the limited ... -
