    This study was conducted to evaluate the use of watermelon pomace and watermelon juice obtained from unmarketable watermelon in the diets of fattening quails. A total of 90 Japanese quails (Coturnix coturnix japonica) wereassigned to three groups (30 quails in each group), each comprising of 5 replicates each having 6 quails. One groupwas designated as control groups whereas other groups fed 5% watermelon pomace or watermelon juice on dry matter basis. All the diets were isonitrogenous and isocaloric formulated in order to meet the nutrient requirements ofquails outlined in NRC standards. Live weight was greater in quails fed watermelon pomace compared with controlgroup in first week only (P0.05). Infirst week and overall period (1 to 4 wk), average daily feed intake (ADFI) was higher in control group than quailsfed watermelon juice which, in turn, was higher in comparison with those fed watermelon pomace (P0.05). In conclusion,it was observed that watermelon pomace can be used in quail diets having additional growth enhancer properties

    The purpose of this study is to evaluate the self-efficacy perceptions and writing anxiety of the Turkish language teacher candidates that receive training for learning and teaching language in a processual context. The research has been carried out with a total of 113 teacher candidates that study at the Department of Turkish Language in the first (n=56) and third (n=57) grades. The reason is that the first graders are beginner and they receive Written Expression classes; and the third graders receive Writing Education classes. The data from both grades have been collected by using the Writing Self-efficacy Perception Scale (WSPS) and the Writing Anxiety Scale (WAS) at the beginning and at the end of the term. The collected data have been analyzed both in respective class levels and by comparing to the other class level. The result of the research shows that the writing anxiety has decreased and the writing self-efficacy perception has increased in the first grader candidates. Whereas in the third grader candidates, the writing anxiety has increased and the writing self-efficacy perception has decreased. This has been interpreted as the professional awareness of the candidates increases depending on the grade level. Another result of the research is that the revision and editing (RE) factor in the writing process is higher in the female candidates than the male candidates. The findings obtained in the research bear a resemblance to the literature in some aspects, and differ from the literature in some aspects

    This study aimed to examine the prevalence of PTSD among undergraduate students and how PTSD affected life balance of undergraduate students who live close to conflict zones. The participants of the study were 253 undergraduate students who lived close to conflict zone and witnessed or experienced bombing or war conflicts. Data collection instruments were Juhnke-Balkin Life Balance Inventory- Turkish Form and Turkish Version of the PTSD Checklist for Diagnostic and Statistical Manual of Mental Disorders Fifth Edition. The data were collected in paper-pencil format one month after bombing by terrorists across the border. Structural equation modeling was used in data analysis. The results indicated that PTSD symptomatology positively affects the students’ depression and sleep disturbance levels. However, PTSD symptomatology negatively affects global health and positive orientation. All effect sizes were in small to large range. We suggest that administrators should invest counseling services and have practioners providing help especially for undergraduate students in conflict zones; and to make families familiar with PTSD symptoms. © 2020, Springer Science+Business Media, LLC, part of Springer Nature

    Genetic diversity and population structure of Saccharomyces cerevisiae isolated from Turkish sourdough by iPBS-retrotransposons markers

    Molecular DNA markers are valuable tools for analyzing genetic variation among yeast from different populations to reveal the genetically different autochthonous strains. In this study, we employed inter-primer binding site (iPBS) retrotransposon polymorphism to assess the genetic variation and population structure of 96 Saccharomyces cerevisiae isolates from four different regions in Turkey. The nine selected iPBS primers amplified 102 reproducible and scorable bands, of which 95.10% were polymorphic with an average of 10.78 polymorphic fragments per primer. The average polymorphism information content and the resolving power were 0.26–3.58, respectively. Analysis of molecular variance (AMOVA) revealed significant (P < 0.001) genetic differences within populations (88%) and between populations (12%). The unweighted pair group mean with arithmetic (UPGMA) dendrogram grouped 96 S. cerevisiae strains into two main clusters, where the highest probability of the data elucidating the population structure was obtained at ΔK = 2. There was not an obvious genetic discrimination of the populations according to geographical regions on UPGMA, supported by principal coordinate analysis. However, the individuals of the closer provinces in each population were more likely to group together or closely. The results indicate that iPBS polymorphism is a useful tool to reveal the genetically diverse autochthonous S. cerevisiae strains that may be important for the production of sourdough or baked goods

    Objectives: The aim of this retrospective study was to investigate the lesions containing mature adipose tissues in surgical materials of the patients who underwent thyroidectomy operation owing to the diagnosis of nodular goiter. Methods: A total of 2800 pathologic specimens of thyroidectomies stained with hematoxylin-eosin were collected between January 2010 and November 2013 in Recep Tayyip Erdogan University School of Medicine. Pathologic sections were selected from pathology archive and re-examined. Upon examination, we determined 10 lesions with mature adipose tissue within thyroid parenchyma. Results: Thyroid lesions containing mature adipose tissue were observed in 10 (0.004 %) of 2800 thyroidectomy materials. Eight of the patients were female and two of them were male. Minimum, maximum and median age of the patients were found to be 31, 74 and 52 years respectively. All of the cases had underwent a bilateral total thyroidectomy operation. In macroscopic examination of the only one cases, a homogenous yellow-gray color was observed. In other cases a large number of colloid-rich nodules of various sizes were observed. On microscopic examination, five adipose tissues in the nodules (adenolipoma-thyrolipoma), four scattered foci of mature adipose tissues (heterotopic adiposis) and one diffuse infiltrating mature adipose tissue on entire thyroid gland (diffuse thyrolipomatosis) were determined among mature adipose tissue containing lesions. A follicular variant of papillary microcarcinoma was found in two of thyrolipoma cases. Conclusion: Nodular thyroid lesions containing mature adipose tissue, as a result of particularly on the outer surface of the gland and parathyroid glands containining mature adipose tissue may mimic parathyroid gland lesion. Therefore, to prevent from inappropriate treatments, pathologists should be aware of these kinds of lesions, especially when they are investigating the lesions of parathyroid glands during an intraoperative consultation

    DP600 ve HSLA300 Sac Malzemelerde Geri Esneme Davranışlarına Proses Parametrelerinin Etkisinin Deneysel Araştırılması

    Get PDF
    Bu çalışmada sac metal malzemelerin oda sıcaklığında bükülerek şekillendirilmesi sonrası gözlenen ve şekillendirmede istenmeyen bir durum olan geri esneme davranışı deneysel olarak araştırılmıştır. Çalışmada DP600 ve HSLA300 sac malzemeler farklı kalıp açılarında ve ütüleme sürelerinde V bükme yöntemiyle şekillendirilmiştir. Çalışma sonunda ütüleme süresinin 10 saniye artmasıyla elastik gerilmelerin kalıcı gerilmelere dönüşmesinden dolayı geri esneme açısının DP600 sac malzemede ortalama %14,8, HSLA sac malzemede ise ortalama %9,7 azaldığı tespit edilmiştir. Kalıp açısının artmasıyla elastik gerilim miktarının da artmasından dolayı her iki malzemede de esneme açısının arttığı, açının büyümesiyle de elastik gerilmelerin dar bir alanda hapsolmasından dolayı da esnemenin daha sonra azaldığı belirlenmiştir. DP600 sac malzemede 15 derece kalıp açısından 45 derece kalıp açısına kadar esnemenin ortalama %15,2 arttığı, 45 dereceden sonra ise %27,6 azaldığı tespit edilmiştir. HSLA sac malzemede ise 15 derece kalıp açısından 30 derece kalıp açısına kadar esnemenin önce ortalama %10,4 arttığı, 30 dereceden sonra ise %26,4 azaldığı gözlenmiştir. Ayrıca DP600 sac malzemenin sertliğinin HSLA sac malzemeden daha yüksek olmasından dolayı oluşan geri esneme değerinin HSLA sac malzemeye göre %12,3 daha yüksek olduğu belirlenmiştir
