Ozek, Fatih; Yıldırım, Onur
Ottoman Turkish is the period of Western Turkish that existed from the 16th to the 20th century. In this period besides literary texts, texts that were far from literary concern were written. In the period of Ottoman Empire, the rulings, orders and prohibitions put forward by the sultans in order to find solutions to the problems faced by the society in religion, state and social issues are called code. Codes, which are very rich sources in terms of both Ottoman history and legal system and the historical vocabulary of Turkish, are texts written without any literary concern. In the study, the Âsafnâme written by Lütfi Pasha during the period of Kânûnî, who prepared the most laws among the sultans and therefore had the title of Kânûnî, will be examined. Lütfi Pasha, who was the grand vizier during the period of Kânûnî, is not only a statesman with his works, but also a writer. Âsafnâme, in which he told his experience to others after him due to the fact that Lütfi Pasha found the state organization complicated and the laws were applied differently from the previous periods has not previously been addressed with language features. In terms of language studies, considering that works written for different purposes other than literary works should be scanned and examined and it is a source for different studies to be carried out and how the palace language is formed and thus it was thought that an original study could be done on the work and the subject of the study was determined. The work in question, the texts with Arabic letters in the copy registered in Istanbul University Library TY.No: 786 will written with transcription signs by reading based on Ahmet Akgündüz's work titled Osmanlı Kânûnnâmeleri ve Hukukî Tahlilleri “Kânûnî Devri Kânûnnâmeleri, 1. Kısım Merkezî Ve Umumî Kânûnnâmeler” (4th book). While writing it down, Ahmet Akgündüz's readings will be taken as basis, and after the texts of the study are composed, the phonetic and morphological information of the work will be examined.

The change and development in the West, which started with the Industrial Revo lution in the mid-1700s, re-arranged the future of the world. Steamships, railways,opened factories; as it rearranges the labor-capital relationship, it also takes theinterstate relations to a more pragmatic dimension. States that grow with thesupport of technological development; they start looking for new colonial areasbecause of new resources, new markets. The prosperity provided by this develop ment and change in the West is admired by the intellectuals of the backward coun tries. In time, the intellectuals/artists of the backward countries begin to emulatethe intellectual resources and artistic accumulation of the developed countries;in this period, which coincides with the decline of the Ottoman Empire, Ottomanintellectuals also emulate the West and clash with their own resources. Turkishpoetry in the Tanzimat period, just like this civilization takes shape at a time of cri sis. The Ottoman intellectual /artist, who forgets that change must pass through acertain thought formation and who is deluded that Western gains can be achievedwith a mere emulational approach, experience great confusion at the thresholdof the distance between what is and what should be. In this study; the conflicts,contradictions and dilemmas in the world of thought and emotion reflected in theTanzimat period Turkish poetry will be traced.

Küçücük bir beden içine hapsolan insan için, yaşadığı dünya bir yandan sürprizlere gebe hoş bir yer bir yandan da içinde gizem ve korku yüklü büyük, tehlikeli ve kaotik bir yerdir. İçinde paradokslar barındıran dünyada yaşam serüvenine başlayan insanın hayatını devam ettirmesi hiç de kolay değildir. İnsan hem dünyadaki her türlü dış etmene hem de bu dış etmenlerin iç dünyasında yarattığı psikolojik faktörlere karşı mücadele etmek zorunda bırakılmıştır. İnsan için yaşam dış dünya ve iç dünya arasında denge kurmakla rayında devam edebilir gibi görünmekte iken her insanın kişisel özelliklerinin farklı olması nedeniyle durum karmaşık bir hal almaktadır. Bu noktada dış dünyadan gelen her türlü tehlikeye karşı insanın yapması gereken ise hem beden sağlığını hem de ruh sağlığını korumaktır. Bu korunmayı sağlayan insan için hayat serüveni biraz daha seyrinde devam edecekken aynı korunmayı sağlayamayan veya dış dünyadan gelen tehlikelere karşı kendini koruyamayacak kadar güçsüz kalanlar için hayat daha da zorlaşmaktadır. Dış bir gerçekliğe sahip insanın tüm yaşananlar karşısında ürettiği iç gerçekliği de edebiyatın ve tiyatronun temel konularından biridir. Bu noktada tiyatroda travma, melankoli, histeri ve nostalji gibi insanın iç gerçekliği veya bilinçdışı ile ilintili tatsız anlatılar üretilmiştir ve üretilmeye de devam etmektedir. Sorbonne Üniversitesi öğretim üyelerinden Solange Ayache, 2017’de yaptığı “‘In-Yer-Head’ Theatre: Staging the Mind in Contemporary British Drama Towards a Quantum Psychopoetics of the Stage” başlıklı doktora tez çalışmasında 2000’li yıllarda İngiliz tiyatrosunda ön plana çıkan bu tatsız anlatıları, Aleks Sierz’in ‘Suratına Tiyatro’ (In-Yer-Face Theatre) kavramına gönderme yaparak ‘Kafana Tiyatro’ (In-Yer-Head Theatre) veya “Akıl Uzamı Tiyatrosu’ (Theatre of Mental Space) örnekleri olarak tanımlamaktadır.

Daimi, Cengiz
On March 21, the day when night and day are equal according to the position of the earth in the face of the sun, new year and spring celebrations were being celebrated in the northern hemisphere. In ancient times, March 21 had been celebrated with festivals organized in the name of gods of abundance and plenitude who died and revived as Akitu in Babel and Prulliyas in Anatolia, around the conflicts of darkness-brightness, summer-winter, birth-death, scarcity-abundance in the mythology. March 21, in this geographical and cultural environment extending from Ancient Egypt to Mesopotamia, from Anatolia to Iran, from India to China and to Rome afterwards, had been commemorated with concepts such asresurrection, rising, equality, peace, salvation and freedom. It is also celebrated in Turkey. Nowruz, which is performed based on the birth of Hazrat Ali, the new year and welcoming of the spring, especially as a ritual of Ayin-i Cem in the community of Alevi and Bektashi, led to creativity in fields of art and culture. Nawruz, led to creativity in many other fields of culture and art such as literature, theatre, music, dance, miniature, painting, gravure, sculpture, sport, philosophy, food, faith thad been subject to works of poets such as Ömer Hayyam, Nizami Gencevi, Mela-i Ciziri, Nesimi, Pir Sultan, Ahmed-i Xani et al. from the 13-14th century’s divan and folk literature. The creativity of Nawruz which is reflected on the literature and music is performed as Nevruziye Poems. We analysed the literary and musical styles of these poems and presented them as a table. As we have seen, Nevruziye poems are mainly based on Nawruz Maqam determined by Safiüddin from Urmia, in the history. These tunes based on Dügâh (La) pitch are on today’s Hüseyni Aşiran and Şur maqam. Nawruz Maqam in the history is the same maqam as Hüseyni Aşiran and Şur maqam. In other words, Nevruziye poems of Nawruz ritual are Koşma form in the literature form and they are on Nawruz Maqam musically.

In this study, the changes in the rheological properties of Gezo pekmez (molasses) samples at different temperature values and their suitability for different rheoleogic models were investigated. In addition, changes in viscoelastic properties of pekmez (molasses) samples at different frequency values were determined. It was determined that the best model describing the rheological behavior of molasses samples at all temperature values was the Power-Law Model. It was detected that K and n values decreased as the temperature values increased. Since phase angle values were greater than 1, it was determined that the fluidity character was more dominant than elasticity character. In other words, molasses samples were found to have viscoelastic properties. It is thought that the result of present study fulfill the lack of information on determining the changes in the rheological properties of the molasses samples.

In this study, the effects of carbon black (CB) additive obtained from waste tires on the moisture performance of hot mix asphalt pavements were investigated. For this purpose, modified asphalts were prepared by adding 5%, 10%, 15% and 20% CB by weight to pure asphalt with penetration class B 160/220. Physical properties of pure and modified asphalts were determined by penetration, softening point and ductility tests, and workability properties were determined by rotational viscometer (RV) test. Then, the optimum asphalt content of the mixture was determined according to Marshall design method by using aggregate and pure asphalt for mixture design. Based on this determined ratio, pure and modified asphalts and hot mix samples were prepared. Pure and CB added modified mixture samples were subjected to Marshall stability, retained Marshall stability (RMS) and indirect tensile strength (ITS) tests. According to the physical test results, it was observed that the hardness and workability temperatures of the modified binders increased with the CB additive. According to the test results of the mixture, it was observed that CB additive had an improving effect on the moisture performance of road pavements due to the significant increases in Marshall stability, RMS and indirect tensile strength ratio (ITSR) values, especially at the rate of 10% CB.

The aim of this study was to evaluate the effect of chrysin on testicular damage induced by carbon tetrachloride (CCl4) in rats. Twenty-four male Spraque-Dawley rats were divided into four groups as the control group, Chrysin group, CCl4 group, and Chrysin+CCl4 group. Chrysin (100 mg/kg/body weight/day) and CCl4 (0.5 ml/kg/body weight/day in corn oil (1:1)) were administered by gavage for 14 days. Compared to the control group, it was determined that malondialdehyde (MDA) level increased, reduced glutathione (GSH) level, and superoxide dismutase (SOD) and catalase (KAT) activities decreased in the CCl4 group. It was also determined that many testicular lesions were induced, Johnsen’s Mean Testicular Biopsy Score (JMTBS) decreased, and caspase-3 immunoreactivity increased in this group. Compared to the CCl4 group, it was determined that GSH level and SOD and CAT activities increased, MDA level decreased in the Chrysin+CCl4 group. It was also observed that testicular lesions were alleviated, JMTBS increased, and caspase-3 immunoreactivity was decreased in this group. As a result, it was concluded that chrysin might have beneficial effects in the treatment of CCl4-induced testicular toxicity as a result of its antioxidant and anti-apoptotic properties.

Bu çalışmada, pozitif yarı eksen üzerindeki bir noktada süreksizlik koşuluna sahip Sturm-Liouville operatörünün ters saçılma problemi ele alınmıştır. Ele alınan sınır değer probleminin saçılma verileri incelenmiştir. Rezolvent operatörü inşa edilmiş ve sınır değer probleminin özfonksiyonlarına göre ayrışım formülü elde edilmiştir. Ters saçılma probleminin temel denklemi veya modifiye edilmiş Marchenko denklemi elde edilmiş ve sınır değer probleminin saçılma verilerine göre potansiyel fonksiyonun inşa edilme algoritması verilmiştir.
