Cem in Rumkale Chepnis RUMKALE ÇEPNİLERİNDE CEM
No full text© 2022 Ankara Haci Bayram Veli University. All rights reserved.The area around Rumkale is one of the areas inhabited by Çepni people, one of the communities that contributed to Anatolia being a Turkish settlement. Religious and non-religious music practices of the ancient people, known in the region as Yavuzeli or Rumkale Alevis, constitute one of the original links of the chain between Anatolian belief and music systems. In this study, which focuses on the music and belief practices of Rumkale Çepnis, the subject of how they perform their cem rituals in the region is discussed in the context of hearth (ocak) practices, bağlama instrument and zākir (performer) tradition. For the research study in which qualitative research methods were used, firstly, all of the Çepni settlements between Yavuzeli district and Rumkale were visited and the cem rituals practiced in Sarılar and Göçmez neighbourhoods, which were chosen as the purposeful sample, were examined. The flow order of the cem rituals, their manners and rules were compared in terms of traditional continuation practices of the hearths, and the similarities and differences between them were revealed. Based on the research data, this study concludes that Rumkale Çepni people were the first Turkmen communities settled in Anatolia. They shaped their worship according to the time of Dede Garkın and Mūsā Kāzım heart, and they have functions of equal importance, together with the symbolic meanings of zākir and gözcü (the watcher), which are integrated with the institution of dede (the spiritual guide) and the bağlama instrument, in the practice and transfer of cem rituals to future generations
Osteoblast response on co-modified titanium surfaces via anodization and electrospinning
No full textWOS: 000327493400020Topography plays a key role in osseointegration and surface modifications at the subcellular level, increasing initial cell attachment in the early period. In the past decade, nanosized texture on metal like a nanotube layer and also more recently extracellular matrix like surface modifications - such as polymeric nanofibrils - have been proposed for a better osseointegration in the literature. Here, we investigate two types of nanoscaled modifications alone and together for the first time. We characterized different types of surface modifications morphologically and investigated how they affected osteoblast cells in vitro, in terms of cell adhesion, proliferation, alkaline phosphatase activity and calcium content. We anodized titanium samples with a thickness of 0.127 mm to obtain a nanotubular titania layer and the silk fibroin (SF), as a biocompatible polymeric material, was electrospun onto both anodized and unanodized samples to acquire 4 sample groups. We analyzed the resulting samples morphologically by scanning electron microscopy (SEM). Cell adhesion, proliferation, alkaline phosphatase (ALP) activity and calcium content were evaluated at 3,7 and 14 days. We found that cell proliferation increased by 70% on the groups having two modifications respect to unmodified titanium and after 7 days, ALP activity and calcium content were 110% and 150%, respectively, higher on surfaces having both surface treatments than that of unmodified group. In conclusion, a nanotube layer and SF nanofibers on a titanium surface enhanced cell attachment and proliferation most. Comodification of titanium surfaces by anodization and SF electrospinning may be useful to enhance osseointegration but it requires in vivo confirmatio
Author Self-Citation in the Turkish Otorhinolaryngology Literature
No full textObjective:To evaluate the prevalence and other characteristics of author self-citations in six Turkey-originated general otorhinolaryngology (ORL) journals of Turkish ORL literature.Methods:A total of 970 articles published in six Turkey-originated general ORL journals (ENT Updates, Journal of Ear Nose Throat and Head Neck Surgery, KBB-Forum, Praxis of Otorhinolaryngology, The Turkish Journal of Ear Nose and Throat, and Turkish Archives of Otorhinolaryngology) in 2016-2020 were analyzed for author self-citations. The association between author self-citations and journal types, study types, study topics, country of origin, and compatibility with the topic were also evaluated.Results:There were 265 author self-citations (0.273 per article) which corresponded to 1.36% of all citations. There was no significant difference between the journal types, study topics, and origin of the studies in terms of mean self-citation values per study, whereas case reports had significantly lower self-citations than review and original investigations. There were three citations (1.1%) that were irrelevant to the study topic.Conclusion:To the best of our knowledge, this is the first study that investigated the practice of author self-citation in Turkish ORL literature. Author self-citation rate in the Turkish-originated general ORL journals was found remarkably lower than the medical literature, whereas the self-citations were found compatible with the study topic to a very large extent. Members of the scientific community including authors, readers, and journal editors should be cautious regarding the unethical practices of self-citations
ÇANAKKALE YÖRESİ TAHTACI TÜRKMENLERİNDE TÖREN, KUTLAMA VE BAYRAM
No full textTahtacı Turkmens in Çanakkale region. We can say that Tahtacıs are communities that contain many cultural codes and have a syncretic structure, and that they also express a rich lifestyle. We see that Tahtacı Turkmens in Çanakkale region have points where they differ from similar communities in the topics we have covered. It is possible to say that we have encountered answers to how they have continued their belief base for centuries both in the field and in the literature. Our study explains the "cem" phenomenon and the basis of this phenomenon when looking at the ceremonial, celebration and holiday practices that the Tahtacı Turkmen identity in Çanakkale region has in the context of belief, and the life cycle. While explaining the origin of Cem, how and by whom it is performed, its varieties, and where it is located in terms of the integration of the belief pattern within the historical development of Tahtacı Turkmen identity, we see the socio-cultural practices and the cultural meaning codes attributed to these practicesBu çalışma Çanakkale yöresindeki Tahtacı Türkmenlerinin tören, kutlama ve bayram inanç ve pratiklerini konu edinmektedir. Tahtacıların birçok kültürel kodu içinde barındıran ve senkretik bir yapıya sahip topluluklar olduğunu, bununla birlikte zengin bir yaşam tarzını ifade ettiğini söyleyebiliriz. Çanakkale yöresindeki Tahtacı Türkmenleri’nin konu edindiğimiz başlıklarda benzer topluluklardan ayrıldığı noktaların olduğunu görmekteyiz. Sahip oldukları inanç temelini yüzyıllar boyunca nasıl devam ettirdiklerine dair cevaplarla hem sahada hem literatürde karşılaştığımızı söylemek mümkündür. Çalışmamız Çanakkale yöresindeki Tahtacı Türkmen kimliğinin sahip olduğu inanç bağlamında, yaşam döngüsü içerisinde geçirdiği tören, kutlama ve bayram pratiklerine bakıldığında “cem” olgusunun ve bu olgunun sahip olduğu temeli açıklamaktadır. Cem’in kökenine nasıl ve kimler tarafından gerçekleştirildiğine, çeşitlerine Tahtacı Türkmen kimliğinin tarihsel gelişimi içerisinde inanç örüntüsü entegrasyonunu bakımından nereden bulunduğunu açıklarken sosyo-kültürel pratikler ve bu pratiklere yüklenen kültürel anlam kodlarını görmekteyiz
An Evaluation of the Second Survey on Electronic Databases Usage at Ankara University Digital Library
No full textPurpose
The study encompasses the assessment of the effectiveness of the digital library and the value of multidisciplinary databases in terms of user preferences and use frequency by academic ranking.
Methodology
This paper compares the results of two survey questionnaires carried out in 2002 and 2005. To examine the level of awareness by academic staff of digital library resources along with their use rate and to evaluate the preferences of faculty for specific electronic databases case studies were undertaken by means of separate questionnaires in both years.
Findings
Findings were consistent that positive results have been observed in two studies conducted in two years, 2002 and 2005. According to the results of current survey, the increase numbers of the faculty members of Ankara University know about the existence of the digital library after the informative activities on databases from. Another result of the survey is that many of the faculty members, although not all of them use electronic databases. The most preferred databases have been Web of Science, Science Direct and Ebsco. When use of the electronic databases is analyzed, in respect of faculty rank and level of awareness, associate and assistant professors, assistants place at first ranges.
Originality/value
The study presents the first case study in the field in Turkey that compares the current situation of the digital library usage with the initial survey data
Sub-lethal effects of two pyrethroids on biological parameters and behavioral responses to host cues in the egg parasitoid Telenomus busseolae
No full textThe present study was undertaken to investigate possible integration of synthetic pyrethroids with biological control of Sesamia nonagrioides Lefebvre (Lepidoptera: Noctuidae) by the egg parasitoid Telenomus busseolae Gahan (Hymenoptera: Scelionidae). The effects of two commonly used synthetic pyrethroids, deltamethrin (Decis Jet 15 EC) and cyfluthrin (Bayteroid 5 EC), on the parasitoid were studied. Lethal concentrations (LC25) were estimated for both insecticides, and their sub-lethal effects on some biological parameters and behavioral responses to different kairomonal cues mediating host location were investigated. Parasitoid females exposed to cyfluthrin (LC25) parasitized significantly fewer eggs than untreated females, whereas neither the level of emergence from parasitized eggs nor the sex ratio of the offspring was affected by the insecticides. None of the above biological parameters were significantly affected by deltamethrin (LC25). Both insecticide treatments reduced the longevity of the parasitoids. The effects of both insecticides (LC25) on the behavioral responses of parasitoid females to the sex pheromone of S. nonagrioides, which acts as a long-distance kairomone, were investigated in a Y-tube olfactometer. Cyfluthrin-treated parasitoids failed to respond to the host pheromone, whereas deltamethrin-treated females responded similarly to untreated females. In addition, sub-lethal effects of pyrethroids on parasitoid arrestment behaviors were evaluated in an open arena containing abdominal scales from virgin female moths, which are a source of short-distance kairomone for the parasitoid. No significant differences in arrestment behaviors (residence time, linear speed) were found. Based on our results, possible consequences of treating maize with cyfluthrin or deltamethrin on the effectiveness of surviving T. busseolae in the field are discussed. (C) 2009 Elsevier Inc.

HABİBZÂDE RODOSLU AHMET KEMAL’İN (1889-1966) CEM SULTAN HAKKINDA BİLİNMEYEN BİR TİYATRO ESERİ [AN UNKNOWN THEATER WORK ABOUT SULTAN CEM BY HABİBZÂDE RODOSLU AHMET KEMAL (1889-1966)]
No full textThis study aims to investigate the theater work titled “Sultan Cem or the Unlucky Prince” by Habibzâde Rodoslu Ahmet Kemal (1889-1966), who stood out with his activities at the Committee for
Union and Progress rather than his literary identity, and who started to be called as “Ahmet Kemal
İlkul” after the acceptance of the surname law. Habibzâde Rodoslu Ahmet Kemal moved from the
island of Rhodes to Istanbul after the announcement of the Second Constitutional Monarchy. He
came together with the members of the Committee for Union and Progress, the ideas of which he was
familiar and of which he felt closeness while he was still on the island of Rhodes during the period
when he was a teacher in Istanbul. Habibzâde Rodoslu Ahmet Kemal worked in the educational
institutions and publication organs of the Committee for Union and Progress and he was personally
given the duty to carry out the educational activities among the Turks in Eastern Turkistan and to
provide contributions to the formation and development of the awareness of being Turkish by Talat
Pasha and Ziya Gökalp. Heretofore, there are nine works of the author that are known and have been found. Whereas, the work titled “Sultan Cem or the Unlucky Prince” is not included in the records of
literature. This work was written in 1328 (1910/1911) and has 40 leaves. The work was not printed,
and the only handwritten manuscript copy is registered at 06 Mil Yz. A. No. 8676 of the Handwritten
Manuscript Collection at the National Library. The work focuses on Cem Sultan’ struggles for the
throne with his older brother Bayezid II, who ascended the throne after the death of their father Sultan
Mehmet the Conqueror and the “difficulties” he suffered on this course. First, in the present study,
Habibzâde Rodoslu Ahmet Kemal and his works are mentioned and then later a careful examination
of the work titled “Sultan Cem or the Unlucky Prince” will be carried out. At the end of the study,
the work will be converted into the Latin alphabet. In this manner, it is aimed both to emphasize the
literary identity of Habibzâde Rodoslu Ahmet Kemal and to fill a gap in the literature history
Silk fibroin/nylon-6 blend nanofilter matrix for copper removal from aqueous solution
No full textWOS: 000353058700010Heavy metal pollution has become a serious problem for living organisms. In this study, silk fibroin (SF)/nylon-6 nanofiber matrices were formed by electrospinning and their surface was modified with calcium phosphate (CaP) crystals to increase the affinity of divalent heavy metals. The properties of matrices were evaluated as a filter matrix for copper adsorption from aqueous solution. Attenuated total reflectance fourier transform infrared spectroscopy (ATR-FTIR), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDXS), X-ray photoelectron spectroscopy (XPS), and alizarin red staining method were used for characterization. Adsorption studies were performed by batch and continuous system. The various parameters regarding adsorption process such as pH of solution, surface area, initial copper concentration, and flow rate were optimized. Toxicity values were assessed before and after the Cu(II) adsorption studies. The resultant SF/nylon-6 nanofiber matrices indicate an excellent fibrous structure without beads (fiber diameter at 250 +/- A 50 nm) and modified successfully with CaP crystals. Adsorption results showed that the removal efficiency of copper could reach 32 % by continuous flow system whereas 77 % by batch system. Acute toxicity bioassays using Vibrio fischeri showed that the toxicity decreased after continuous and batch flow systems. For desorption study, different concentrations of various desorption solutions were used and the percentage of Cu(II) desorption was determined as 11 %, approximately.TUBITAK (The Scientific and Technical Research Council of Turkey) [111T671]This study was financially supported by TUBITAK (The Scientific and Technical Research Council of Turkey) under the Grant No. 111T671
