Mixing angles between the tetraquark states with two heavy quarks within QCD sum rules
LHCb collaboration has recently announced the observation of a doubly charmed tetraquark T-cc (u) over bar(d) over bar(+) state with spin parity J(P) = 1(+) . This exotic state can be explained as a molecular state with small binding energy. According to conventional quark model, both (D+D0)* and ((DD+)-D-0*) multiquark states are expected to have the same mass and flavor in the exact SU(3) symmetry. However, since the quark masses are different, SU(3)(SU(2)) symmetry is violated; hence, the mass and flavor eigenstates do not coincide. The mass eigenstates can be represented as a linear combination of the flavor eigenstates, which is characterized by the mixing angle theta. In the present work, the possible mixing angles between the T-cc states are calculated. Moreover, the analyses are extended for all the possible tetraquarks scenarios with two heavy and two light quarks within the molecular picture although those states have not been observed yet. Our prediction on mixing angle between doubly charmed tetraquark states shows that SU(3) symmetry breaking is around 7% maximally
New formulae for Zagreb indices
International Conference on Numerical Analysis and Applied Mathematics (ICNAAM) -- SEP 19-25, 2016 -- Rhodes, GREECEIn this paper, we study with some graph descriptors also called topological indices. These descriptors are useful in determination of some properties of chemical structures and preferred to some earlier descriptors as they are more practical. Especially the first and second Zagreb indices together with the first and second multiplicative Zagreb indices are considered and they are calculated in terms of the smallest and largest vertex degrees and vertex number for some well-known classes of graphs.Uludag UniversityUludag University [F-2015/17, F-2015/23]; Selcuk UniversitySelcuk UniversityThe first author was supported by the Research Fund of Uludag University project no: F-2015/17, F-2015/23.

FASIH AHMED DEDE'S MASNAVI BEHIST-ABAD
In this article, 17th century Mevlevi poet Fasih Ahmed Dede's masnavi Behis-abad the copies of which was not detected so far was introduced. Masnavi written at 1698, was prepared as traditional mesnevi arrangement. In this moral mesnevi which consists of 1229 couplet; the themes are about real friendship and fidelity. Besides, the author focused on the form and content features of the masnavi
Copies of the poem siret written by Muhammad in the XVth century-I
"Siret", more commonly called "siyer", is the general name of the works on the life of the Prophet. At first, the word "siret", which was used for such works, was commonly used as "siyer". "Siret / siyer", whose first examples were in Arabic literature, begins to be seen in Turkish literature in XIVth century. First known in Turkish literature is Siretuzn-nebi, written in verse and prose by Darir in the second half of the XIVth century. the first example of what is known today is the Siret, which is a subject written by an author named Muhammed in the XVth century. the work is around 15,500 couplets. the fact that there are many archaic words in the book makes it important for Turkish language and literature. From the beginning of 872[1467] when Siret was written, many copies and stone print have been made. This shows that it has been loved and read a lot. However, none of the sixty-nine copies identified yielded the work of Muhammad's style. It is seen that some copiers and stone printers of Siret put their names by removing the name of the author. It is understood that a change of this kind is due to the desire to own the work. in this article, the copies of Siret will be introduced in Turkey and abroad. the evaluation of the studies and copies will be the subject of the next article
CORRUPTED MAGIC TO ENCHANT THE WORLD
In this study, a book about Corrupted Magic to enchant the world which was written by George Ritzer, is introduced. A life centered on the axis of consumption of the modern era is the general subject of the book. We are in an ongoing cycle consumption consumption by author said that we live in society. An environment for consumption of social life at every moment being created. A continuous consumption of the community with new tools withdrawal consumption is concerned. Fashion, brand, advertising and consumption with luxury elements is kept alive each year
A LITERARY GENRE UNKNOWN SUFFICIENTLY IN THE CLASSICAL LITERATURE: RUZNAME AND AN EXAMPLE OF IT BY AN UNKNOWN AUTHOR
Classical Turkish literature is a kind of literature which based on poetry. Almost everything that is meant to be told in this literary traditon has been expressed in verse. For this reason, many different genres which include different subjects were written up in poetic way. In this study, an example of the type of ruz-name, which is rarely encountered and less known in the classical literture tardition, is discusssed. The word ruz-name, which means daily writing in Persian, has been used in Turkish historyand culture to cover more than one different genre in different fields. One of them is a literary genre that is about to days of the month or week, in which mentions what is genarally good to do and what is bad to do in these time periods.In this ruz-name, which were analysed, seven days of the week were discussed. In ruz-name daytimes were divided into seven parts; dawn, mid-morning, decadence of day, midday, interval between two prayers, mid-afternoon and sunset. Nighttime also divided into seven parts; occident, evening, ishareyn, midnight, suluseyn, sulusurl-ahir and aurora. By telling which celestial body is dominant on which day of the week at these time periods, the auspicious and omnious deeds at that time are explained
ODES OF BEYANI-ZADE AYANI
Ottoman Intellectuals were generally interested in poetry no matter what their professions were. Some of them proceeded to produce poetry and prepare their own "Divans" or "Divance" (anthology of poems), while the poems of the poets who did not have enough poems to compile a divan were either lost or remained scattered here and there. "Beyani-zade Ayani", too, was one of our poets who could not constitute a "Divan" or "Divance". Here, as a result of our investigations, we have found poems by Ayani, who we presume to be the son of Beyani Effendi, author of a collection of biographies, in a journal including 262 couplets composed of 47 odes, 2 stanzas and 5 couplets (mufred) and we present them to the attention of researchers. We think that Beyani-zade Ayani, who is understood to have an elevated sense of poetry, might have other peoms, too
SOCIOLOGICAL IMAGINATION IN THE NOVELS OF PEYAMI SAFA
This study is including a series analysis to aim to reveal the fundamental ideas of Peyami Safa based on his novel of 'All Alone'. Overall, a discussion was held on the issues, themes, and fiction characters addressed by Peyami Safa in his novels. The author's thoughts, ideas and other works have also been included for holistic assessment in this study. Also, technical and thematical analysis was made on the novel. Event construction and analysis of the fiction character, choice of space and lifestyle analysis, actual time-real time elements are discussed in detail. Author's fiction of 'Simerenya' has been underlined. The study are examined the themes and fiction characters of the author within the context of main sociological discussions. In this respect, the fundamental problem of Turkish Modernization which is Westernization is discussed. Peyami Safa reveals the condition of the individuals who grew up in the family model which is detached from the traditional and which only faces the West. Spiritual-mystical point of view is put to the forefront and lack of materialistic perspective in addressing the reality is emphasized. He stated that solutions in solving problems outside the positivist methodology is possible and dogmatic perspectives may represent a perspective that goes no further than limiting the human mind. Safa emphasizes that modernist or traditionalist attitude will be a mistake, what needs to be done in the final stage is to achieve the synthesis of both
Studies on the Poem Siret Written by Muhammad in the 15th Century and Written Copies of Siret-II
Siret was written by an author named Muhammed in the 15th century. There is not any information about Muhammad in the sources examined. Siret has many copies in Turkey and abroad. in addition, stone prints were made in the late 19th and early 20th centuries. Many of the copies have missing parts to detect its writer. Some of the copies whose writer is known have been recorded in different names due to carelessness. As a result, the name of the work and the writer's name have been recorded in twenty-one and nineteen different ways, respectively. Because of this confusion, some studies conducted on the work are inaccurate. It is understood that while copies and stone prints were being created, some additions and subtractions were made to the work. This situation makes it difficult to put forward a solid text. in the article, information will be given about the studies on Siret and the records of the identified copies will be evaluated. in addition, the deficiencies in the records will be investigated and the reasons for the wrong records will be explained
