    BACKGROUND: The aim of our study was to objectively compare Cytyc Thinprep(® )and other methods of obtaining thin layer cytologic preparations (cytocentrifugation, direct smearing and Millipore(® )filtration) in urine cytopathology. METHODS: Thinprep slides were compared to direct smears in 79 cases. Cytocentrifugation carried out with the Thermo Shandon Cytospin(® )4 was compared to Thinprep in 106 cases, and comparison with Millipore filtration followed by blotting was obtained in 22 cases. Quality was assessed by scoring cellularity, fixation, red blood cells, leukocytes and nuclear abnormalities. RESULTS: The data show that 1) smearing allows good overall results to be obtained, 2) Cytocentrifugation with reusable TPX(® )chambers should be avoided, 3) Cytocentrifugation using disposable chambers (Cytofunnels(® )or Megafunnel(® )chambers) gives excellent results equalling or surpassing Thinprep and 4) Millipore filtration should be avoided, owing to its poor global quality. Despite differences in quality, the techniques studied have no impact on the diagnostic accuracy as evaluated by the rate of abnormalities. CONCLUSION: We conclude that conventional methods such as cytocentrifugation remain the most appropriate ones for current treatment of urinary samples. Cytyc Thinprep processing, owing to its cost, could be used essentially for cytology-based molecular studies

    © 2020 The Linnean Society of London, Biological Journal of the Linnean Society. Spiny mice of the Acomys cahirinus group display a complex geographical structure in the Eastern Mediterranean area, as shown by previous genetic and chromosomal studies. To better elucidate the evolutionary relationships between insular populations from Crete and Cyprus and continental populations from North Africa and Cilicia in Turkey, genetic and morphometric variations were investigated, based on mitochondrial D-loop sequences, and the size and shape of the first upper molar. The Cypriot and the Cilician populations show idiosyncratic divergence in molar size and shape, while Cretan populations present a geographical structure with at least three differentiated subpopulations, as shown by congruent distributions of haplogroups, Robertsonian fusions and morphometric variation. A complex history of multiple introductions is probably responsible for this structure, and insular isolation coupled with habitat shift should have further promoted a pronounced and rapid morphological evolution in molar size and shape on Crete and Cyprus

    The study group of this research, which is planned to develop the Sustainable Scale of Earthquake Awareness, consists of the students studying at Duzce University in the academic year 2018-2019. 276 volunteer individuals (213 females, 63 males) participated to the research group determined by random sampling method. For confirmatory factor analysis, 434 female and 129 male volunteer students participated. 839 students, 647 of them were females (77,12%) and 192 of them were males (22,88%), supported the study. As a result of the exploratory factor analysis which is completed after testing the suitability of the data for analysis, the scale was constituted of three sub-factors consisting of 22 items. The factors that make up the scale explain 46,393% of the variance. The sub-factors of the scale were named based on the knowledge about the earthquake. The suitability of the obtained model was 0.072 for RMSEA; 0.90 for NFI, 0,89 for GFI, 0.063 for RMR and 0.86 for AGFI. As a result of the reliability analysis, the internal consistency coefficient (Cronbach alpha) of the scale was determined as 0.884. It is thought that this developed scale will provide support as a tool for educational purposes. It is recommended to carry out different researches that can help to investigate the awareness level about the earthquake with different variables. © 2021, International Electronic Journal of Environmental Education.

    The Gezi protests: An outburst at Turkey's shatter-zone

    No full text
    The purpose of this paper is to examine the social and political causes of the Gezi protests, and their long- and short-term impact on Turkey's domestic landscape. As part of our endeavor to enrich the conversation over the protests, this paper puts in context both the meaning and media coverage of the Gezi protests. This in turn will explain how on the one hand a protest over a particular environmental dispute escalated into vulgar anti-Erdo?an slogans and wild Tahrir comparisons, but on the other hand faded away without leaving a mark on Turkey's national political map. Following our analysis of the Gezi Park phenomenon, we will offer our view of its implications

    Modelling of Turkey's net energy consumption using artificial neural network

    No full text
    The main goal of this study is to develop the equations for forecasting net energy consumption (NEC) using artificial neural network (ANN) technique in order to determine the future level of the energy consumption in Turkey. Two different models were used in order to train the neural network: (i) Population, gross generation, installed capacity and years are used in input layer of network (Model 1). (ii) Energy sources are used in input layer of network (Model 2). The NEC is in output layer for two models. R2 values for training data are equal to 0.99944 and 0.99913, for Model 1 and Model 2, respectively. Similarly, R2 values for testing data are equal to 0.997386 and 0.999558 for Model 1 and Model 2, respectively. According to the results, the NEC prediction using ANN technique will be helpful in developing highly applicable and productive planning for energy policies.

    A new species of voles, Microtus elbeyli sp. nov., from Turkey with taxonomic overview of social voles distributed in southeastern Anatolia

    There are twelve Microtus species in Turkey and two of them are endemic to the steppic central Anatolian plateau. In this study, previously collected specimens that were recorded as Microtus irani from southeastern Turkey were reevaluated by karyologically comparing different species distributed throughout southeastern Turkey. The taxonomic status of this species was raised to a new species, Microtus elbeyli sp. nov., which has dark ochreous dorsal color, agrestis morphotype in M2, and 2n = 46, NF = 50, NFa = 46 karyotype. The new species described here raises the total number of Microtus species in Turkey to 13 and endemic vole species in Anatolia to three. © TÜBİTAK

    Turkey's net energy consumption

    No full text
    The main goal of this study is to develop the equations for forecasting net energy consumption (NEC) using an artificial neural-network (ANN) technique in order to determine the future level of energy consumption in Turkey. In this study, two different models were used in order to train the neural network. In one of them, population, gross generation, installed capacity and years are used in the input layer of the network (Model 1). Other energy sources are used in input layer of network (Model 2). The net energy consumption is in the output layer for two models. Data from 1975 to 2003 are used for the training. Three years (1981, 1994 and 2003) are used only as test data to confirm this method. The statistical coefficients of multiple determinations (R 2-value) for training data are equal to 0.99944 and 0.99913 for Models 1 and 2, respectively. Similarly, R2 values for testing data are equal to 0.997386 and 0.999558 for Models 1 and 2, respectively. According to the results, the net energy consumption using the ANN technique has been predicted with acceptable accuracy. Apart from reducing the whole time required, with the ANN approach, it is possible to find solutions that make energy applications more viable and thus more attractive to potential users. It is also expected that this study will be helpful in developing highly applicable energy policies. © 2004 Elsevier Ltd. All rights reserved

    No full text
    This study aimed to determine the influence of selected individual and situational features on burnout among nurse academics. The Maslach Burnout Inventory was used to assess the burnout levels of academics. The sample population comprised 94 female participant. The emotion exhaustion (EE) score of the nurse academics was 16.43±5.97, the depersonalization (DP) score was 4.83±3.62, and the personal achievement (PA) score was 22.27±4.27. Thirty years and below of the academics reported a lower level of PA than 31 and above of academics (p 0.05). Future studies should investigate the relationship between roles of the nurse academics and burnout. © The Turkish Online Journal of Educational Technology
