Bu çalışma 2008'2009 yıllarında Adnan Menderes Üniversitesi Ziraat Fakültesi Araştırma ve Uygulama çiftliği deneme tarlalarında, basit faktöriyel tesadüf blokları deneme desenine göre dört tekerrürlü olarak yapılmıştır. Bazı ekmeklik buğday çeşitlerinin (Cumhuriyet'75, Kaşifbey'95, Meta2002, Sagittario) farklı bitki sıklıklarının (200'300'400'500'600 bitki/m2) verim ve verim öğeleri üzerine etkisinin belirlenmesi amacıyla yürütülmüştür. Çalışmada; bitki boyu, başak boyu, metrekarede bitki sayısı, metrekarede başak sayısı, başakta tane sayısı, başakta başakçık sayısı, bin tane tane ağırlığı, tane verimi ve tek başak verimi gibi agronomik ve verim özellikleri incelenmiştir. Çeşitler ve farklı bitki sıklığı uygulamalarının denemede incelenen çoğu agronomik ve verim öğelerinin birçoğu üzerinde etkisinin önemli olduğu saptanmıştır Sonuçta, metrekarede bitki sayısı, 600 bitki/m2 ekim sıklığında en yüksek değere ulaşılırken, çeşitler arasındaki farklılıkların önemli olmadığı kaydedilmiştir. Metrekarede başak sayısında çeşit*sıklık interaksiyonu önemli bulunmuş, çeşit*sıklık interaksiyon ortalaması 414.3 (başak/m2) olarak belirlenmiştir. Başakta tane sayısı ve başakta başakçık sayısında çeşitlerinde etkisi önemli bulunurken, başakta tane sayısı ve başakta başakçık sayısı 200 tohum/m2 ekim sıklığında en yüksek değere ulaştığı saptanmıştır. Çeşitler arasında en yüksek tane verimi Kaşifbey'95 (360.6 kg/da) çeşidinden elde edilirken, farklı bitki sıklıklarının tane verimi üzerine etkisinin önemli olmadığının saptanmasıyla bölgemiz koşullarında en uygun ekim sıklığının 200 tohum/m2 altında bir ekim sıklığının uygulanabileceği sonucuna varılmıştır.In this study, in 2008'2009, Adnan Menderes University Faculty of Agriculture, Research and Practice in a farm field experiment, a simple factorial randomized block design with four replications was carried out as.

Determination of human T-lymphocyte apoptosis mediated by bacterial heat shock protein

Thesis (Master)--Izmir Institute of Technology, Molecular Biology and Genetics, Izmir, 2009Includes bibliographical references (leaves: 26-29)Text in English; Abstract: Turkish and Englishix, 29 leavesPeriodontal diseases are the most common inflammatory disease worldwide which caused by the pathogenic organism living in biofilm. Aggregatibacter Actinomycetemcomitans (Aa) is the main player of the periodontitis disease pathology. Although some of the virulence factors of Aa has been identified up to now, its cytotoxic mechanism has not been clearly known yet. Although known virulence factors of Aa; ltx and cdt has been knocked out, the mutant Aa strains have retained the ability to induce apoptosis. Depending on the literature there must be another important virulence factor. 64kDa GroEL protein which is a molecular chaperone and a heat shock protein can be the potential candidate for being a virulence factor. AaGroEL protein has not been studied in terms of apoptosis up to now and it is not known how AaGroEL mediate immune regulation of T cells. In this study AaGroEL protein has been purified by using ATP Affinity chromatography and electroelution methods. After the purification step lps contamination has been removed by detoxi-gel endotoxin removal gel and detected by LAL Assay. Peripheral Blood Mononuclear Cells (PBMCs) were isolated by Ficoll Hypaque Density Gradient Centrifugation method. It was found that AaGroEL protein induces T cell apoptosis in dose and a time dependent manner. AaGroEL protein mediated T cell apoptosis has been detected by plasma membrane changes, activation of caspase-3 and DNA fragmentation. In conclusion, AaGroEL has antigenic properties that effect T lymphocytes by regulating immune response that would play important role in periodontal pathology

Comparative empirical analysis on the effect of mortgage loan on capital adequacy ratio / Yusuf Dinç

Capital adequacy ratio is the main indicator for banks to proceed with their operations. Standards for the calculation of the ratio are based on Basel Accord. Key factor for the calculation is credit risk. Credit risk is a function of credit and collateral type. In this case, mortgage has lower risk weight based on its collateral structure on credit risk. This research evaluates the effects of mortgages on capital adequacy ratio to understand the effects of collateral based credits. The findings show positive results between capital adequacy ratio and mortgages of participation banks. However, mortgages have negative impact on capital adequacy ratio of conventional banks. Participation and conventional banks of Turkey are compared on linear regression to analyse the effects of mortgages on capital adequacy ratio. Results are important for further research and professionals

Method development for protein identification with MALDI-TOF/TOF by using on-surface digestion

Thesis (Master)--İzmir Institute of Technology, Chemistry, İzmir, 2012Includes bibliographical references (leaves: 49-54)Text in English; Abstract: Turkish and Englishx, 58 leavesProtein identification is predominantly carried out by searching tandem mass spectrometric data of peptides in a protein database. For this reason, proteins are converted to peptides through a digestion process by using some certain endoproteinases. Trypsin is mostly preferred in this sample preparation step due to its high activity and products having appropriate mass range. Whereas in-solution digestion method is applied for the proteins in solution, proteins trapped in the gel can be digested by using in-gel digestion technique. Alternative to these traditional digestion methods, it has been reported that proteins can be digested too while they were adsorbed onto solid surfaces. In this study, digestion process of the adsorbed proteins, namely on-surface digestion is examined widely by using both hydrophobic and ionic adsorbents on different proteins. Results of the on-surface digestion were compared with in-solution digestion and in-gel digestion methods. As a conclusion, on-surface digestion is applicable for the protein identification by mass spectrometry; however, its yield may change from one experiment to another, depending on two separate but related processes: protein adsorption before the digestion and peptide recovery after the digestion. Nevertheless on-surface digestion has the advantages of protein enrichment and protein purification prior to mass spectrometry. These processes are necessary and significant especially for the samples containing minute amounts of protein and an effective enzymatic activity. Last but not least, this method may be performed complementarily to other digestion methods since new and different peptides may be acquired from the same sample source

Exploring effective music teaching strategies of primary school teachers

AbstractThis study aims to investigate primary teachers’ teaching strategies in music Turkish primary classrooms. In the study the ‘qualitative’ research approach was adopted in order to fulfil the aims and objectives of the study. The study carried out in two state primary schools in Turkey. Total of six primary school teachers with different educational backgrounds participated in the study. Semi-structured interviews and classroom observations were used as tools for data collection. Findings suggest that there is a range of factors influence teachers’ music teaching activities in negative ways in classrooms. These factors were encountered as students, curriculum, lack of teacher competencies, inadequate facilities and resources for music education, limited support from parents and negative effects of audio-visual media. It is suggested that due to the lack of confidence and competence of primary teachers, music specialist teachers should be assigned to the task of delivering music curriculum

An Investigation of the Factors Hindering Adults’ Participation in Physical Activity

This study focuses on the non-participation of adults in physical activity and the reasons that have been preventing them to participate. The study is carried out with 283 participants (116 men and 167 women) who live in Adana, Turkey. Their ages range from 18-66. The average age of the adult participants is 31.81 ±10.12. The demographical features, their conditions to be able to participate in physical activity and the conditions that restrain them from participation have been determined by the 35 question through a questionnaire prepared by the researcher. In analyzing the information the x² test has been used. According to the results of the analysis it is found out that 59.5% of the man and 53.7% of the woman who have participated in the study are involved in physical activities.. In the study it has been observed that participation in physical activity increases in direct proportion to better education and higher income. The marital status has also affected the participation. The participants have brought to the fore the most important reasons for not participating in physical activities as, not finding friends, that the places where physical activity is performed is crowded, not having enough time, not being supported by the family or not having enough information in their answers. As a result, participation in physical activity is made up by factors related to each other and at the same time independent of them
