Paksoy, Mehmet Yavuz; Sevindik, Emre; Topseçer, Feyzanur; Aydoğan, Melike
In this study, we performed a genetic diversity analysis using RAPD (Random AmplifiedPolymorphic DNA) and ISSR (Inter simple sequence repeat) markers for some Chrysochamelaspecies growing in Turkey. PCR was performed using RAPD and ISSR primers and genomic DNAsamples from each specimen, and the resulting bands were scored. Phylogenetic relationships andgenetic distances between the studied taxa were calculated using the PAUP analysis program.According to the RAPD analysis, the closest genetic distance was found to be 0.20000 between C.noeana populations, while the most distant values were found as 0.60000 between C. noeana and C.elliptica. The ISSR analysis also revealed the closest genetic distance as 0.34043 between C. noeanapopulations, while the most distant values were found to be 0.55319 between C. noeana and C.elliptica. UPGMA (unweighted pair group method with arithmetic mean) dendrogram generated forboth RAPD and ISSR analyses consisted of two groups. As a result, it was found that RAPD datawere more appropriate for comparison with the previous anatomical and morphological data of the studied taxa.

Öğütcü, Murat
The 1960s and the 1970s witnessed the transition in British sports from amateurism toprofessionalism. Thereafter, sportspersons have obtained material opportunities withsponsorships and attracted entrepreneurs. However, since sponsors in this new era havebeen using sportspersons to manipulate consumer behaviour, the vested interests ofcapitalists led to the misuse of the media and medical industry at the cost of the health ofsportspersons. The commodifcation of sports has put much pressure on sportspersons forsportive success. This pressure, on the other hand, has been tried to be circumvented bythe illegal use of doping. Although sportspersons in countries of the Iron Curtain were statesponsored, thus were not pressed by entrepreneurs for sportive success, they faced asimilar pressure by their states. To show their political superiority, countries of the IronCurtain forced their sportspersons to use doping. Louise Page in her Golden Girls (1984)criticises, in a light tone, the politics of sports in the Britain of the 1980s. She looks at theresult of the transformation of sports from amateurism to professionalism, deals with thefree use of doping in Iron Curtain countries to contrast it with the illegal use of doping incapitalist Britain, and focuses on the topical issues about British sportswomen and theoppression they have felt because of their gender by the male dominated world of sports.Therefore, this article will frst give a brief history of the development of athletics in Britainfrom the 1960s onwards, then the relationship between media and sports thatcommodifes sports in the Britain of the 1980s, and lastly the use and effects of doping asthey are refected in Golden Girls.

Birinci Dünya Savaşı'ndan sonra İskoç şiirinde öne çıkan İskoç ulusal kimlik bilinci ile ilgili konular, İskoç bağımsızlık hareketinin başlaması ve yüzyıl dönümü İskoç şiirinde belli başlı geleneksel yazınsal özelliklerin ortaya çıkmasında önemli bir rol oynamıştır. Çağdaş bir İskoç şairi olan Kathleen Jamie, söz konusu ulusal kimlik konusunu yazınına taşıyan yazarlardan birisi olmuştur. Genelde Jamie doğa ve çevre ile ilintili konulara odaklansa da eserlerinde, İskoçya ve İskoç kültürü konularına da yer vermektedir. Hatta yazar, 1999'da İskoçya'da, sonucunda bağımsız bir İskoç Parlamentosu hakkı elde edilen bağımsızlık hareketine de katkıda bulunmuştur. Jamie, bağımsızlığın tutkulu bir destekçisi olarak, şiirlerinde İskoçya'nın kültürel geçmişi, kimliği ve mevcut siyasi durumunu ve bunun yanı sıra lehçeleri ve siyasi tarihini de ele almaktadır. Bu bağlamda, bu çalışma, İskoçya'nın ulusal kimliğinin, siyasi durumunun ve kültürünün ele alındığı “Interregnum” ve “23/09/14” adlı şiirlerine odaklanacaktır. Söz konusu şiirler sırasıyla Jamie'nin 1997 referandumu sırasında yazmış olduğu Jizzen (1999) ve 2014 bağımsızlık referandumu sürecinde yazmış olduğu The Bonniest Companie (2014) adlı şiir kitaplarından alınmıştır.

Öğütcü, Murat
14. yüzyılın sonlarından 17. yüzyılın başlarına kadar, Troilus ve Criseyde konusu hem İngiltere hem de İskoçya’da benzer ama birbirinden farklı olarak ele alınmıştı. Chaucer’ın Troilus ve Criseyde (1385 civarı) adlı eserinde dünyevi ve ilahi aşkın çatışması tartışmalı biçimde tasvir edilmektedir. Henryson’ın Cresseid’in İfadesi (1480 civarı) adlı eseri ise Chaucer’dan kendisine intikal eden boşlukları doldurmak için bir İskoç veya daha doğrusu bir Katolik bakış açısıyla cevap verdiği ve fikrini beyan ettiği görülmektedir. Ancak, İngiltere ve İskoçya ilişkilerinde yeni bir dönemeç Truva konusunun sahneye taşınmasıyla görülecektir. Shakespeare’in Troilus ve Cressida (1602 civarı) adlı eseri Chaucer ve Henryson’un yorumlarını birleştirmektedir. Chaucer’ı kullanarak sadece İngiliz geleneğini devam ettirdiği düşünülse de, Henryson’u kullanarak bu gelenekten uzaklaştığı ve I. Elizabeth tarafından yönetilip İskoçya Kralı VI. James’in İngiliz tahtının en güçlü varislerinden olduğu bir dönemde İskoç geleneğini benimsediği görülmektedir. Böylece eser sayesinde iki ülke edebi anlamda birleşmektedir, ki bu birleşme siyasi olarak İngiltere Kralı I. James sayesinde de gerçekleşecektir. Böylece, Troilus ve Criseyde konusu İskoç-İngiliz ilişkilerini ve karşılıklı edebi etkileşimleri aydınlatmaktadır. Bundan dolayı bu makalenin amacı Chaucer, Henryson ve Shakespeare’in Troilus ve Criseyde konusunu ele alışlarını karşılaştırmaktır.

Yön, Burak; Onat, Onur; Öncü, Mehmet Emin
Infill and partition walls as nonstructural elements are generally constructed with hollow brick masonry and briquette as single or multilayered vertical walls. The seismic responses of infill walls and reinforced concrete (RC) framed buildings have been investigated with field observations after earthquakes all over the world. This study focuses on the reasons infill and partition walls failed as a result of the October 23, 2011 (Mw=7.2), and November 9, 2011 (Mw=5.7), Van earthquakes in Turkey. In this paper, in-plane, out-of-plane, and combined failure mechanisms of single and multilayered infill walls enclosed within reinforced concrete structures were investigated, and construction rules were suggested. To limit the failure of nonstructural elements enclosed within an RC frame, design and construction requirements should be included in the seismic code by adopting suitable solutions for both in-plane and out-of-plane behavior. This paper will be a reference for future studies that investigate infill wall damage. (c) 2019 American Society of Civil Engineers.

Gündüzalp, Seda; Özan, Mukadder Boydak
This study aims to discover the pygmalion effect, which suggests to affect a person's expectations from other people on the actions of those people, by taking the opinions of primary school teachers. In order for the study to reach its goal, triangulation technique, which is a mixed method design, has been used. A likert-type five-point scale made up of 18 items and a semi-structured interview form comprising two open-ended questions have been used to acquire data. The scale has applied to take the opinions of teachers working at the schools administered by 25 managers mastering in a postgraduate program without thesis at the Education Management Inspection Planning and Economy Department of Firat University Institute of Education Sciences. The quantitative and qualitative data acquired have been analyzed by means of statistical softwares. It has been concluded from the findings acquired from teachers' views reveal the reality and accuracy of pygmalion effect in the field of education, and show that high expectations pave the way for teachers' motivation, effort, active working, commitment as well as the growth of their enthusiasm. It is seen that high expectations will generally reveal high performance, while low expectations, due to their negative effects on employees, will cause decrease in motivation as well as unwillingness towards the job being done and therefore, a decline or stability in performance.

The toxic effects cadmium (Cd), which is a heavy metal, on human erythrocytes and protective effects of N-acetyl-L-cysteine (NAC) on lipid peroxidation and antioxidant enzymes were investigated. The effects of 1, 50, 150 mu M doses of cadmium and 1mM NAC on the level of malondialdehyde (MDA) in human erythrocytes and superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx) enzyme activities were investigated. When the Cd was applied alone, it was found that MDA level increased in erythrocytes and SOD, CAT and GPx activities decreased. No statistically significant difference was observed when 1mM NAC administered erythrocytes were compared with the control cells. However, the beneficial effect was seen only in administration doses of Cd at the levels of I and 50 mu M and NAC was observed to have a protective effect. As a result, NAC partially reduced the toxic effect caused by Cd on erythrocytes but could not completely prevent it.

Onat, Onur
It is very common to find an empirical formulation in an earthquake design code to calculate fundamental vibration period of a structural system. Fundamental vibration period or frequency is a key parameter to provide adequate information pertinent to dynamic characteristics and performance assessment of a structure. This parameter enables to assess seismic demand of a structure. It is possible to find an empirical formulation related to reinforced concrete structures, masonry towers and slender masonry structures. Calculated natural vibration frequencies suggested by empirical formulation in the literatures has not suits in a high accuracy to the case of rest of the historical masonry bridges due to different construction techniques and wide variety of material properties. For the listed reasons, estimation of fundamental frequency gets harder. This paper aims to present an empirical formulation through Mean Square Error study to find ambient vibration frequency of historical masonry bridges by using a non-linear regression model. For this purpose, a series of data collected from literature especially focused on the finite element models of historical masonry bridges modelled in a full scale to get first global natural frequency, unit weight and elasticity modulus of used dominant material based on homogenization approach, length, height and width of the masonry bridge and main span length were considered to predict natural vibration frequency. An empirical formulation is proposed with 81% accuracy. Also, this study draw attention that this accuracy decreases to 35%, if the modulus of elasticity and unit weight are ignored.

Recently, various types of additives are being used to enhance the properties of bitumen. Until now, few researchers have handled the utilization of different additives in the same binder. In this study, styrene-butadiene-styrene (SBS) and Evotherm were used both separately and in the same blend. Dynamic shear rheometer (DSR) and bending beam rheometer (BBR) tests were applied to SBS and Evotherm modified binders. SBS and Evotherm were added to pure bitumen in three different ratios. Sixteen different combinations were produced using the two additives, and a pure binder in the same binder was evaluated in the DSR test. Eight different combinations were evaluated in the BBR test. The conclusion reached was that the maximum usage of Evotherm (0.9%) induces a 20% reduction in the rutting parameter of both the 5% and 6% SBS modified binders. The 0.5% Evotherm with 4% and 5% SBS modification does not have an adverse effect on rutting performance. Evotherm modification could prevent the stiffness increment that originates from using the SBS additive, especially at high content. Using 0.7% Evotherm with 4% SBS can acquire the pure binder's low temperature performance. (c) 2019 American Society of Civil Engineers.

Considering the advantages of nanoscale materials such as being lighter, more robust, programmable materials, less material usage, less energy requirement during production phase, and no longer producing materials, it is important to produce nanomaterials and determine their properties. Therefore, the characterization of nanomaterials has become one of the pillars of material science. An important aspect of nanoscale material science is the method of characterization of materials that we use or study to learn more about them. In recent years, great importance has been given to rare earth materials with nanostructures. One of the rare earth elements is Erbium and it is one of the newly discovered materials that is used in high technology. Erbium oxide (Er2O3) nanoparticles (NPs) are used in electronic devices. It is used in capacitors, metal oxide semiconductor transistors, and as dopants for optical fiber and laser materials. In this study, Erbium based Er2O3 NPs were characterized. The characterization of Er2O3 was realized using X-ray diffraction (XRD), scanning electron microscopy (SEM), the energy dispersive X-ray (EDX), and Fourier transform infrared spectroscopy (FT-IR). The number of specific peaks and their position fit very well with those from standard XRD spectrum and revealed pure Er2O3 nano oxide. SEM analysis of these particles showed their spherical shapes that are in great extent uniform distributed with nano sizes ranged between 40-60 nm.

To investigate the effects of carvacrol supplementation in rainbow trout induced by lipopolysaccharide (LPS), relative gene expressions levels of some pro-inflammatory cytokines and apoptosis markers in kidney and liver were measured. Fish with a mean weight of 44.71 +/- 1.33 g were studied using four different treatments with three replicates each. Inflammation and apoptosis were performed using LPS of Escherichia coli (25 mu g ml(-1)) except in the control group and only carvacrol (100 mu g ml(-1) diet) containing diets were fed to this group (CAR). The last group was the infected fish fed carvacrol supplemented diet (+CAR). Kidney and liver tissues were removed 3 days after to determine the levels of interleukin-1 beta (IL-1 beta), interferon gamma (INF-gamma), caspase 3 (Cas 3), caspase 8 (Cas 8) using Real-Time PCR analyses. IL-1 beta expressions of both kidney and liver was significantly decreased (12.9 and 2.14 fold, respectively) in LPS treated cells (p<0.05). While IFN-gamma expression was up regulated in kidney, it had down regulation in liver. LPS decreased both Cas 3 and 8 expressions in kidney but increased in liver. +CAR increased expressions of IL-1 beta and IFN-gamma compared with the control (up to 2-3 fold) in all tissues except caspase gene expressions that were similar in the control. In all tissues, IL-1 beta and IFN-gamma expressions increased in +CAR group, expect IFN-gamma in the kidney. However, Cas 3 and 8 expressions including apoptosis was induced by up-down regulations in all tissues compared to LPS-injected fish. The results showed that carvacrol had pro-inflammatory and apoptotic effects especially on liver tissue of LPS-induced inflammation model of Oncorhynchus mykiss.

In this research, it was aimed to determine the level of teachers' proactive personality traits predicting the problem-solving skills consisting of the sub-dimensions of confidence in problem-solving ability, personal control and approach-avoidance. The relational screening model was used in this research which was prepared in accordance with the quantitative research paradigm. Accordingly, the concept of proactive personality was discussed as an independent variable, and problem solving skills were discussed as dependent variables. It is seen that there is a positive and significant relationship between teachers' proactive personality traits and problem solving skills and confidence in problem-solving ability, approach-avoidance and personal control, which are the sub-dimensions of problem solving. Based on the ANOVA values are examined for all three sub-dimensions, it could be said that the value p is significant, in other words, the regression model is valid. According to the t-test results regarding the significance of the regression coefficients, it is seen that proactive personality traits are a significant predictor on the sub-dimensions of confidence in problem solving ability, approach-avoidance and personal control. Furthermore, according to Durbin-Watson values for all sub-dimensions, the assumption that there is no relationship between error terms is confirmed.

Baloglu, Ulas Baran; Yildirim, Ozal
Background and objective: Deep learning structures have recently achieved remarkable success in the field of machine learning. Convolutional neural networks (CNN) in image processing and long-short term memory (LSTM) in the time-series analysis are commonly used deep learning algorithms. Healthcare applications of deep learning algorithms provide important contributions for computer-aided diagnosis research. In this study, convolutional long-short term memory (CLSTM) network was used for automatic classification of EEG signals and automatic seizure detection. Methods: A new nine-layer deep network model consisting of convolutional and LSTM layers was designed. The signals processed in the convolutional layers were given as an input to the LSTM network whose outputs were processed in densely connected neural network layers. The EEG data is appropriate for a model having 1-D convolution layers. A bidirectional model was employed in the LSTM layer. Results: Bonn University EEG database with five different datasets was used for experimental studies. In this database, each dataset contains 23.6 s duration 100 single channel EEG segments which consist of 4097 dimensional samples (173.61 Hz). Eight two-class and three three-class clinical scenarios were examined. When the experimental results were evaluated, it was seen that the proposed model had high accuracy on both binary and ternary classification tasks. Conclusions: The proposed end-to-end learning structure showed a good performance without using any hand-crafted feature extraction or shallow classifiers to detect the seizures. The model does not require filtering, and also automatically learns to filter the input as well. As a result, the proposed model can process long duration EEG signals without applying segmentation, and can detect epileptic seizures automatically by using the correlation of ictal and interictal signals of raw data.

O. argentata Hub.Mor., O. neglecta Riedl, O. proballanthera Rech. f, O. rechingeri Riedl, O. sericea Willd. and O. stenoloba Hausskn. ex Riedl from Turky were investigated. Stem anatomy revealed that cuticle layer ranged from 0.6 mu m in O. argentata to 1.7 mu m in O. proballanthera. Parenchymatous cells of O. neglecta and O. stenoloba possessed more intense starch than the other species studied. In leaf anatomy, the longest palisade parenchyma was found in O. neglecta, while the smallest was noted in O. argentata. Mesophyll structure of O. argentata, O. sericea and O. rechingeri was equifacial (isobilateral), while O. neglecta, O. proballanthera and O. stenoloba presented bifacial (dorsiventral) structure. Rugose nutlet ornamentation was observed in O. argentata, O. neglecta and O. sericea, whereas reticulate type was found in O. proballanthera, O. rechingeri and O. stenoloba. Onosma stenoloba could easily be distinguished from other species by its aesterotrichous indumentum, and in contrary, other species possessed haplotrichous type of indumentum. Micromorphological features of nutlet surface, anatomical features of epidermal surface (trichomes and stomata), and lamina mesophyll structure (dorsiventral and isobilateral) could be useful in solving taxonomic problem of the genus.

Sançar, Taylan; Zabci, Cengiz; Karabacak, Volkan; Yazici, Muge; Akyüz, H. Serdar
The sinistral Malatya-Ovack Fault Zone (MOFZ) is one of the outstanding intraplate deformation belts within Anatolia. The 165-km-long, NE-SW-striking Malatya Fault (MF), which constitutes the southern section of the MOFZ, is separated into five segments according to its surface geometry. These segments have evident morphotectonic features that reflect long- and short-term fault activity, such as morphologic structures offset by as little as 7m and as much as 7.3km. This study provides results from the first paleoseismological investigations on the MF. We find that the last earthquake occurred between 965 and 549 BCE and calculate a recurrence interval of 2275 +/- 605years from evidence for four paleo-events over the last 10ka. Considering fault segmentation and our paleoseismological data, we propose that the accumulated strain on the MF may cause a destructive earthquake (M=7.4) in the near future. Our results support the hypotheses that the MF and other NW-striking dextral and NE-striking sinistral strike-slip faults within the eastern part of Anatolia are plate boundary-related, active deformational structures.
