    Aims: This study was carried out in the laboratories of Hatay Mustafa Kemal University, Faculty of Agriculture, Department of Field Crops in 2019 in order to determine the suitability of 5 foreign originated quinoa cultivars that can be adapted to areas with salinity problems. Methods and Results: In order to determine the tolerance to salt stress, 50 seeds were placed in each petri dishes. The research was conducted in a germination cabinet with 4 replications according to the factorial arrangement in completely randomized plot design. In this research, germination rate (GR), germination index (GI), mean germination time (MGT), radicle length (RL) and plumula length (PL) and fresh seedling weight (FSW) values of different salt concentration levels were examined. The used cultivars showed different reactions to salt stress level. As the salt concentration increased, germination rate, germination index, radicle length, plumule length and fresh plant weight decreased while the mean germination time was prolonged. Conclusions: As a result of the research, it was found that there were cultivars of quinoa that can germinate and develop even at a high salt concentration such as 400 mM and that can be cultivated even in soils with salinity problems. Significance and Impact of the Study: Every year, agricultural areas with salinity problems are increasing in many part of the world as in Turkey. Determining quinoa cultivars which are tolerant to different level of salinity in terms of germination and development can provide valuable information for evaluation of arable lands which has salinity problem.Amaç: Bu çalışma ülkemizde tuzluluk problemi olan tarım alanları için tuzlu koşullara adapte olabilecek uygun kinoa çeşitlerin belirlenmesi amacı ile 2019 yılında Hatay Mustafa Kemal Üniversitesi Ziraat Fakültesi Tarla Bitkileri Bölümü laboratuvarlarında yürütülmüş olup, çalışmada materyal olarak yabancı orjinli 5 adet kinoa çeşidinin tohumu kullanılmıştır.

    No full text
    Renewable energy as one of the current and substantial issue needs to be investigated in terms of political outlook. So the researches on renewable energy policies under the energy policies of different countries are necessary. The emergence of renewable energy policy was the 20th century but it gained momentum in 21st century. The realization of the polluting nature of the petroleum products, their negative environment effects and the assumptions about the future of non-renewable energy sources were the driving forces behind these politics. The European Union in these conditions tries to play pioneer role. Turkey on the other hand as a candidate country has to harmonize its policies with the Union's. In this context, objective of this work is to examine the EU and Turkey's renewable energy policies, make a comparison and as a sustainability of Turkish renewable energy policy construct a future projection in short, medium and long terms.

    No full text
    Birinci Dünya Savaşı’nda, Çanakkale cephesi savaşları 1915’te yaşanır. Ancak Türk edebiyatında müstakil bir Çanakkale romanı görmek ancak Mustafa Necati Sepetçioğlu’nun 1989’da yayımlanmaya başlanan …ve Çanakkale Geldiler, …ve Çanakkale Gördüler, …ve Çanakkale Döndüler adlı üç ciltlik eseri ile mümkün olur. Türk tarihi açısından önemli bir dönüm noktası olan Çanakkale savaşı bunlardan sonra başka romanlara da konu olur. Eserlerin bir kısmı doğrudan Çanakkale savaşını konu ederken bir kısmı dolaylı olarak bu savaşa değinir. Türkiye’deki önemli tartışma konularından biri Mustafa Kemal’in Çanakkale savaşlarına etkisi ya da katkısıdır. Bazıları onun bu savaşta önemli bir etkisi, katkısı bulunmadığını, bazıları ise bu savaşın Mustafa Kemal sayesinde kazanıldığını söyler. Gerçek hayatta yaşanan bu tartışma roman türüne nasıl yansımıştır, romanlarda Mustafa Kemal’e ne kadar yer verilmiştir sorularının cevabı olmak üzere bu çalışmanın amacı; 1989’dan sonra yayımlanmış ve Çanakkale savaşlarını işleyen Çanakkale Mahşeri (1999), Zulüm Dağları Aşar Çanakkale İçinde (2000), Tarihe Sığmayan Destan Çanakkale (2003), Gelibolu Yenilmezlerin Yenildiği Yer (2004), Çanakkale’de Çocuklar da Savaştı (2006), Diriliş Çanakkale 1915 (2008), 57. Alay Çanakkale (2008), Çanakkale Askerine Rütbe Gerekmez (2017), Uzun Beyaz Bulut Gelibolu (2001) ve Şafakta Yanan Mumlar (2003) adlı romanlarda; kara savaşlarının başladığı 25 Nisan 1915’ten Çanakkale savaşının sonuna kadar ve savaştan sonra, Mustafa Kemal’e nasıl ve ne kadar yer verildiği veya ona nasıl bir misyon yüklendiğini ortaya koymaktır. İncelememize konu edilen romanların hiçbirinde Mustafa Kemal’i eleştiren veya onu olumsuz gösteren bir ifade, bir örnek yoktur. Fakat her bir yazar Mustafa Kemal’i farklı misyon ve ağırlıkta işler. Romanların tamamında Mustafa Kemal ileri görüşlü, çalışkan, iyi yetişmiş, vatanın geleceğinden endişe duyan, gözünü budaktan sakınmayan, doğru stratejiler geliştiren bir kişi olarak yansıtılır.In the First World War, the battles of the Çanakkale front take place in 1915. However, it is only possible to see an independent Çanakkale novel in Turkish literature with Mustafa Necati Sepetçioğlu's three-volume work titled ...ve Çanakkale Geldiler, ve Çanakkale Gördüler, ve Çanakkale Döndüler, which was published in 1989. The Battle of Çanakkale, an important turning point in Turkish history, became the subject of other novels. While some of these novels directly deal with the Gallipoli War, others indirectly touch upon it. One of the major topics of debate in Turkey is Mustafa Kemal's influence or contribution to the battle of Gallipoli. Some say that he had no significant influence or contribution in this war, while others say that this war was won thanks to Mustafa Kemal. The purpose of this study is to answer the questions of how this real-life debate is reflected in the novel genre, and how much space is given to Mustafa Kemal in novels. The novels published after 1989 and dealing with the Çanakkale wars are Çanakkale Mahşeri (1999), Zulüm Dağları Aşar Çanakkale İçinde (2000), Tarihe Sığmayan Destan Çanakkale (2003), Gelibolu Yenilmezlerin Yenildiği Yer (2004), Çanakkale'de Çocuklar da Savaştı (2006), Diriliş Çanakkale 1915 (2008), 57. Alay Çanakkale (2008), Çanakkale Askerine Rütbe Gerekmez (2017), Uzun Beyaz Bulut Gelibolu (2001) and Şafakta Yanan Mumlar (2003); from April 25, 1915, when the land battles started, until the end of the Çanakkale War and after the war, to reveal how and how much Mustafa Kemal is given place or what kind of mission is attributed to him. In none of the novels subject to our analysis is there any expression or example that criticizes Mustafa Kemal or shows him negatively. However, each author treats Mustafa Kemal with a different mission and weight. In all the novels, Mustafa Kemal is portrayed as a farsighted, hardworking, well-educated person who is concerned about the future of the homeland, who does not spare any effort and develops the right strategies

    The purpose of this study is to investigate the thermal performance of heat recovery system with gravity assisted heat pipe charged R134a and R410A working fluids and also determine the usefulness of heat pipe bundle system in heat recovery applications. For this purpose an experimental test rig was designed and built. Series of experimental tests were carried out by varying the flue gas temperature (75, 100, 125, 150 and 175 degrees C), flue gas velocity (1, 1.5, 2 and 2.5 m/s) and cooling water flow rates (1, 2, 3 and 4 l/min). Values of the overall effectiveness of the heat pipe heat recovery system are shown to vary with the flue gas velocity, as expected, but the results also allow the prediction of effectiveness variation with the variation of the flue gas temperature. Effectiveness of the heat pipe for both working fluids R134a and R410A has been varied averagely between 35.6% and 57.7% with a good agreement with the published results. Quantitatively, it is found that R134a working fluid is 14% more effective than R410A in heat pipe bundle system. (C) 2016 Elsevier Ltd. All rights reserved

    No full text
    The aim of this study is to find out the optimum operating conditions in a diesel engine fueled with compressed biogas (CBG) and pilot diesel dual-fuel. One-dimensional (1D) and three-dimensional (3D) computational fluid dynamics (CFD) code and multiobjective optimization code were employed to investigate the influence of CBG-diesel dual-fuel combustion performance and exhaust emissions on a diesel engine. In this paper, 1D engine code and multiobjective optimization code were coupled and evaluated about 15000 cases to define the proper boundary conditions. In addition, selected single diesel fuel (dodecane) and dual-fuel (CBG-diesel) combustion modes were modeled to compare the engine performances and exhaust emission characteristics by using CFD code under various operating conditions. In optimization study, start of pilot diesel fuel injection, CBG-diesel flow rate, and engine speed were optimized and selected cases were compared using CFD code. CBG and diesel fuels were defined as leading reactants using user defined code. The results showed that significantly lower NOx emissions were emitted under dual-fuel operation for all cases compared to single-fuel mode at all engine load conditions

    A review of regression diagnostics for behavioral research

    No full text
    Influential data points can affect the results of a regression analysis; for example, the usual summary statistics and tests of significance may be misleading. The importance of regression diagnostics in detecting influential points is discussed, and five statistics are recommended for the applied researcher. The suggested diagnostics were used on a small dataset to detect an influential data point, and the effects were analyzed. Colinearity-based diagnostics also are discussed and illustrated on the same dataset. The nonrobustness of the least squares estimates in the presence of influential points is emphasized. Diagnostics for multiple influential points, multivariate regression, multicolinearity, nonlinear regression, and other multivariate procedures also are discussed. Index terms: Andrew-Pregibon measure, colinearity, Cook’s distance, covariance ratio, influential observations, measurement error, partial residual plot, regression diagnostics.Chatterjee, Sangit; Yilmaz, Mustafa.

    YILMAZ, Mustafa/0000-0001-9929-910XWOS: 000494129100001PubMed: 31462172Public building stock in Turkey is getting older and more funds are transferred for repairs and maintenance of these public buildings. Parallel to this growth, a significant increase is observed in the number of occupational accidents occurring in the Turkish construction sector. This case study focuses on compulsory investments in small or middle-scale repairs and maintenance projects of public buildings. In the determination of occupational health and safety (OHS) costs which are an integral part of the project costs, a model combining risk-based activity analysis and activity-based cost analysis is utilized and computer software developed as a calculation instrument for this model is used. The ratio of actual and estimated OHS costs to the approximate cost was found to be 3.98 and 3.58%, respectively. Further research should be conducted to test the reliability of this model and its calculation tool in estimating the actual OHS cost before the tender stage
