Mustafa Kemal University , abbreviaed as MKU, is a public university established 1992 at Antakya, Hatay Province in southern Turkey. It is named after the founder of the Turkish Republic, Mustafa Kemal Atatürk.It comprises eleven faculties, five four-year colleges, 15 two-year vocational schools, three post-graduate institutes, nine research centers, a conservatory and a university hospital. In 2010 the student enrolment of Mustafa Kemal University reached approximately 24,900 in total. The total size of the teaching faculty is 967. The main campus of the university is located in Serinyol area, 15 km north of Antakya. In 2007, the Faculty of Engineering moved from Antakya to İskenderun.The MKU is an active member of European University Association since 2001. Wikipedia.

This paper examines the long run and causal relationship issues between economic growth, carbon emissions, energy consumption and employment ratio in Turkey by using autoregressive distributed lag bounds testing approach of cointegration. Empirical results for Turkey over the period 1968-2005 suggest an evidence of a long-run relationship between the variables at 5% significance level in Turkey. The estimated income elasticity of carbon emissions per capita is -0.606 and the income elasticity of energy consumption per capita is 1.375. Results for the existence and direction of Granger causality show that neither carbon emissions per capita nor energy consumption per capita cause real GDP per capita, but employment ratio causes real GDP per capita in the short run. In addition, EKC hypothesis at causal framework by using a linear logarithmic model is not valid in Turkish case. The overall results indicates that energy conservation policies, such as rationing energy consumption and controlling carbon dioxide emissions, are likely to have no adverse effect on the real output growth of Turkey. © 2010 Elsevier Ltd.

In this study, a new chitosan derivative (ketimine) was synthesized by condensation of chitosan with 4,6-diacetylresorcinol (DAR) at heterogeneous medium. The ketimine derivative of chitosan (DAR-chitosan) was characterized by elemental (C, H, N), spectral (DR-UV-vis and FT-IR spectroscopy), structural (powder XRD), and morphological (SEM) analyses. The degree of substitution (DS) of DAR-chitosan was evaluated by elemental analysis and 13C CP-MAS NMR spectroscopy and found to be around 12%. The copper (II) metal complex of DAR-chitosan was prepared and characterized by FT-IR, DR-UV-vis and inductively coupled plasma-atomic emission spectroscopy (ICP-AES). Thermal behaviors of the synthesized compounds were investigated by DSC and TG-DTG-DTA analysis. The catalytic activity of copper (II) complex of chitosan derivative (DAR-chitosan-Cu) was investigated on hydrogen peroxide decomposition. The copper chelate showed high efficiency (over 80%) towards the decomposition of hydrogen peroxide as heterogeneous catalyst. © 2012 Elsevier Ltd. All rights reserved.

This study investigated potential synergistic activities between tar sand and walnut shell during co-pyrolysis. A series of pyrolysis studies were conducted under specific operating conditions in a fixed-bed reactor. The highest yield of bio-oil from the co-pyrolysis was 31.84. wt.%, which represented an increase of 7.88. wt.% compared to the bio-oil yield from the pyrolysis of walnut shell alone. The bio-oils were characterized using various spectroscopic and chromatographic analysis techniques. The results indicated that the synergetic effect increased the co-pyrolysis bio-oil yield and its quality. Consequently, the results indicate that the bio-oils obtained will be suitable for the production of fuels and chemicals as feedstock after required improvements. © 2011 Elsevier Ltd.

Microbial lipase from T. lanuginosus was immobilized onto polyglutaraldehyde-activated olive pomace powder. The support was used to produce biodiesel with pomace oil and methanol. Response Surface Methodology (RSM) in combination with Central Composite Design (CCD) was used to optimize the biodiesel production parameters. Reaction temperature, molar ratio of methanol to oil, biocatalyst content and reaction time were chosen as the variables and the response selected was the yield of pomace oil methyl ester in present work. A quadratic polynomial equation was obtained for pomace oil methyl ester yield by multiple regression analysis. The optimal conditions for the transesterification have been found to be: reaction temperature of 40 °C, alcohol/oil molar ratio of 5.3:1, biocatalyst content of 5.8% w/w and reaction time of 24 h. The predicted pomace oil methyl ester yield was 92.87% under the optimal conditions. Verification experiment (91.81%) confirmed the validity of the predicted model. Biodiesel yield reached 93.73% by adding water (1% w/w) in reaction medium under the optimal conditions. Immobilized lipase was used to determine operational stability and it indicated that immobilized lipase was stable retaining more than 80% residual activity after being used repeatedly for 10 consecutive batches of pomace oil transesterification. © 2012 Elsevier B.V.

The friction stir welding (FSW) technique is widely accepted to be one of the most significant welding techniques to emerge in the last 20 years. Friction stir welding of Al-alloys is now commonplace and is covered in several recent reviews, including one in this journal. Consequently, the technique is currently being used for joining of these alloys in various industrial applications. Complementary to these developments has been a dramatic increase in research into joining of other alloys and systems by FSW. This field is very active, but less mature. Thus, the aim of this review article is to build on our understanding of the fundamentals, as applied to Al-alloys that laid out in the previous review in this journal, and to address the current state-of-the-art of FSW developing beyond Al-alloys, including Mg-alloys, Cu-alloys, steels, Tialloys and metal matrix composites, focusing particularly on microstructural aspects, including texture formation, and the resulting properties of these joints. Material selection for tooling will also be covered to some extent while modelling studies of material flow during FSW are outside the scope of this paper. Finally, residual stresses are mentioned in a number of places and while these have been measured extensively for Al-alloy systems there are fewer measurements for other systems. © 2011 Institute of Materials, Minerals and Mining and ASM International.
