An assessment of mining efficiency in Turkish lignite industry
(Elsevier Science, 2015)This article focuses on the mining activities of Turkish Coal Enterprises (TKI) the major lignite supplier in Turkey. First we analyzed the lignite production and overburden removal activities of TKI from a historical ... -
Carboxylic acid derivatives display potential selectivity for human histone deacetylase 6: Structure-based virtual screening molecular docking and dynamics simulation studies
(Elsevier Science, 2018)Human histone deacetylase 6 (HDAC6) has been shown to play a major role in oncogenic cell transformation via deacetylation of alpha-tubulin making it a viable target of anticancer drug design and development. The crystal ... -
Contraction and deletion blockers for perfect graphs and H-free graphs
(Elsevier Science, 2018)We study the following problem: for given integers d k and graph G can we reduce some fixed graph parameter pi of G by at least d via at most k graph operations from some fixed set S? As parameters we take the chromatic ... -
Critical phenomenon during photoinitiated gelation at different temperatures: A Photo-DSC study
(Elsevier Science, 2011)The behaviour of photoinitiated radical polymerization of an 80 wt% epoxy diacrylate (EA) and 20 wt% tripropyleneglycoldiacrylate (TPGDA) mixture with 2-mercaptothioxanthone (TX-SH) photoinitiator was studied at different ... -
The effect of a bump in an elastic tube on wave propagation in a viscous fluid of variable viscosity
(Elsevier Science, 2007)In the present work treating the arteries as a thin walled prestressed elastic tube with a bump and the blood as a Newtonian fluid of variable viscosity we have studied the propagation of weakly nonlinear waves in such a ... -
The effects of Dea:water ratio on the properties of ZnO nanofilms obtained by spin coating method
(Elsevier Science, 2014)In this work the ZnO were fabricated with the sol-gel spin coating method and the effects of the Dea:water ratios on the properties of the as-prepared ZnO thin films were determined by using a X-ray diffractometer transmission ... -
Fluorescence study of film formation from PS/Al2O3 nanocomposites
(Elsevier Science, 2014)Steady state fluorescence (SSF) and UV-vis (UVV) techniques were used to study the film formation behavior of pyrene (P) labeled polystyrene (PS) latex and Al2O3 (PS/Al2O3) composites depending on PS particles size and ... -
Forecasting the Coal Production: Hubbert Curve Application on Turkey's Lignite Fields
(Elsevier Science, 2016)The dependence on imported energy sources is one of the biggest challenges that Turkey and many other similar countries face in the 21st Century and the gap between production and consumption cannot be decreased without ... -
In situ steady state fluorescence (SSF) technique to study drying of PAAm hydrogels made of various cross-linker contents
(Elsevier Science, 2009)Drying experiments of polyacrylamide (PAAm) gels were performed using steady-state fluorescence (SSF) spectrometer. Pyranine (P) was introduced as a fluorescence probe and intensity of P from various crosslinker content ... -
Lignite resources of Turkey: Geology reserves and exploration history
(Elsevier Science, 2014)This article aims to emphasize the importance of lignite which is the mostly used domestic energy source in the Turkish energy mix by briefly overviewing its geology reserves and exploration. Lignites are distributed in ... -
Optical energy band gap of PAAm-GO composites
(Elsevier Science, 2018)Graphene oxide (GO) can be used as an electron acceptor for polymers. The generation of the exciton in such materials is intimately related to the optical band gap. Polyacrylamide (PAAm) - graphene oxide (GO) composites ... -
Scheduling a log transport system using simulated annealing
(Elsevier Science, 2014)The log truck scheduling problem under capacity constraints and time window constraints is an NP-hard problem that involves the design of best possible routes for a set of trucks serving multiple loggers and mills. The ... -
Thermal rearrangement of 2-acetoxy-266-trimethylbicyclo[3.1.0]hexane: Theoretical elucidation of the mechanism
(Elsevier Science, 2007)Bicyclohexenes are believed to be the immediate precursors of aromatic compounds. As a part of the exploratory study of thermal aromatization reactions 266-trimethylbicyclo[3.1.0]hexan-2-ol and its ester derivative ... -
Turkish public preferences for energy
(Elsevier Science, 2018)Public concern over energy supplies prices sustainability and efficiency has emerged as a major issue around the world. Yet most of what we know regarding public opinion on energy comes from North America and Europe. This ...
