Abstract:
Recaizade Mahmut Ekrem , who was one of the intellectuals in the Reform Era, is an important figur in the westernisation period. Being different from many intellectuals at that time, he was not interested in politics but was deeply interested in art and literature. Ekrem, who was among the second generation artists of the Reform Era, had his first essays related to old literatue understanding but his following works made him one of the important figures of Western literature. Ekrem started to publish hid first works in Da arc k Journal, which was published by Ahmet Mithat Efendi and he had experience thanks to his translations from Western literature. Ekrem, who was taken as a model by many men of letters, especially by Servet-i Fün n understanding, attracted intention with his opinions on various topics. He expressed his opinions generally in his works called Talim-i Edebiyat (1879), III. Zemzeme ( ns zünde), Takdir-i Elhan (1886), Pejmürde (1895) and Takrizat (1898). His opinions on “Classical Ottoman Poetry”, “Folk Literature”, “Religion” and “Culture” showed that he was an innovative artist who was in pursuit of novelties. Ekrem was not totally against to the old literature understanding but it was seen that he had some suggestions and criticism about the need to renew and improve himself. His evaluations about folk literature are inadequate and even scarce. Ekrem, who had more tradidtional opinions about religion and things related to religion, was seen to behave very sensitively towards values belonging to religion. Together with being an artist who was in favour of western values in terms of cultural concepts, he criticizes cultural degeneration by opposing to westernisation blindly.

Abstract:
New Turkish literature has been shaped with the Tanzimat. Newspapers and magazines publish works of literary journals have led to assume the function of the book. Therefore, when writing of literary history or a first place to look at whether the works are being compiled must first Ottoman periodicals. Has an important place in our literary history periodicals is one of the Revnak magazine. In this study, Emin Nihad’s, Osman Nevres’s, Edhem Pertev Pahsa’s and Recai-zade Mahmut Ekrem’s works will be introduced which were remained in the magazine's Revnak. And also index of periodicals scanned the interests of the Ottoman literary history for our new importance will be emphasized.

Abstract:
Ali Ekrem Bolay r was one of the most versatile eminent personage of Turkish bureaucracy, literary, political, and educational life of the near past.It s a fact that the discovery of new information and documents will enlighten many of the aspects of his biography. In this respect, I think, the documents most of which exist in the Uzluk archieve of Research Center of Sel uk University will add considerably what is already known about the writer.In this study his life has been revalued under the light of these documents and recent studies. This paper also presents some photographs to the observation of other researchers.

Abstract:
Eudemonia, a key concept of Aristotelian philosophy, is one of the major ethical terms that have been adopted and employed by the Muslim moralists. The Muslim philosophers divided philosophy into theoretical and practical, expounding their conceptions of morality within the latter. K nal zade is one of these philosophers who adopted the eudemonist theory of morality. For him, the attainment of eudemonia occurs through the acquisition of virtues and turning them into established habits. Man attains eudemonia in the hereafter once he attains it in this world. Man seeks to become happy by nature and this becomes possible only when one fulfills the prerequisites of theoretical philosophy along with those of practical philosophy. Those who realize both practical and theoretical philosophy may attain eudemonia. This paper is intended to address the eudemonistic morality of K nal zade with a view to the meanings he attributed to practical and theoretical philosophy.

Abstract:
A group-word w is called concise if whenever the set of w-values in a group G is finite it always follows that the verbal subgroup w(G) is finite. More generally, a word w is said to be concise in a class of groups X if whenever the set of w-values is finite for a group G in X, it always follows that w(G) is finite. P. Hall asked whether every word is concise. Due to Ivanov the answer to this problem is known to be negative. It is still an open problem whether every word is concise in the class of residually finite groups. A word w is rational if the number of solutions to the equation w=g is the same as the number of solutions to w=g^e for every finite group G and for every e relatively prime to |G|. We observe that any rational word is concise in the class of residually finite groups. Further we give a sufficient condition for rationality of a word. This is used to produce a new family of words that are concise in the class of residually finite groups.

Abstract:
We have studied the recA transcriptional regulation in S. thermophilus, a bacterium that does not contain a LexA homologue. We have characterized the promoter region of the gene and observed that its expression is strongly induced by DNA damage. The analysis of deletion mutants and of translational gene fusions showed that a DNA region of 83 base pairs, containg the recA promoter and the transcriptional start site, is sufficient to ensure normal expression of the gene. Unlike LexA of E. coli, the factor controlling recA expression in S. thermophilus acts in a RecA-independent way since recA induction was observed in a strain carrying a recA null mutation.In S. thermophilus, as in many other bacteria,recA expression is strongly induced by DNA damage, however, in this organism expression of the gene is controlled by a factor different from those well characterized in other bacteria. A small DNA region extending from 62 base pairs upstream of the recA transcriptional start site to 21 base pairs downstream of it carries all the information needed for normal regulation of the S. thermophilus recA gene.The bacterial RecA protein has an important role in a variety of cellular processes, such as the control of DNA status, repair of stalled replication forks, double-strand break repair, general recombination, induction of the SOS response and induction of temperate phages [1]. RecA has also been recently shown to possess other roles related to DNA metabolism, such as the apparent motor function in which DNA strand exchange is coupled to ATP hydrolysis [2]. In addition, roles of RecA in degradation of pectin in Erwinia carotovora [3], expression of adherence factors in Vibrio cholerae [4], pilus phase transition in Neisseria gonorrhoeae [5] and switching from pathogenic smooth to non-pathogenic rough cell form in Pseudomonas tolaasii [6], have been proposed and explained as secondary effects of RecA action on DNA structure and function.However, RecA has been also associated t

Kaytaz-zade Mehmet Naz m Efendi is accepted one of the late-biggest poets among the Cypriot poets who use the prosody successfully. His poems carries different characteristics in terms of content, form, language and expression since it has been written on transition period in 19th century. Kaytaz-zade Mehmet Naz m Efendi’s poems include both the ottoman poetry characteristics and the effects of changing poem apprehension. In our paper, we will introduce Kaytaz-zade Mehmet Naz m Efendi and will analyse his R h- Mecr h Poems’ stanzas in terms of form, content, language and expression. Also, we will try to show the relationship between his stanzas and ottoman poems examples.

With decline of the authority of the Ottoman Centralization policiesthroughout the 18th century, the Feudal systems called Ayan emerged inthe regions which were far away from the center government domain. Assoon as Mahmut II came to power, he adopted the policies which wouldstrengthen the central authority in that regions. While doing reforms, hetried to control and suppress the Ayan uprisings. He managed this, tosome extent, in Balkans and Anatolia. The central organization wasestablished by the Sivas province governor Re it Pasha in Easternprovince was significantly completed by Haf z Pasha in 1839. 18. yüzy l boyunca Osmanl Merkez otoritesinin zay flamas ylabirlikte merkezden uzak olan b lgelerde ayan denilen feodal yap lanmalarortaya km t r.

Abstract:
A few years ago N.A'Campo invented a construction of a link from a real curve immersed into a disk. In the case of the curve originating from the real morsification method the link is isotopic to the link of the corresponding singularity. There are some curves which do not occur in the singularity theory. In this article we describe the Casson invariant of A'Campo's knots as a J^{+/-}-type invariant of the immersed curves. Thus we get an integral generalization of the Gusein-Zade--Natanzon theorem which says that the Arf invariant of a singularity is equal to J^{-}/2(mod 2) of the corresponding immersed curve. It turns out that this invariant is a second order invariant of the mixed J^{+}- and J^{-}-types.

Abstract:
A group-word w is called concise if whenever the set of w-values in a group G is finite it always follows that the verbal subgroup w(G) is finite. More generally, a word w is said to be concise in a class of groups X if whenever the set of w-values is finite for a group $G\in X$, it always follows that w(G) is finite. P. Hall asked whether every word is concise. Due to Ivanov the answer to this problem is known to be negative. Dan Segal asked whether every word is concise in the class of residually finite groups. In this direction we prove that if w is a multilinear commutator and q is a prime-power, then the word $w^q$ is indeed concise in the class of residually finite groups. Further, we show that in the case where $w=\gamma_{k}$ the word $w^q$ is boundedly concise in the class of residually finite groups. It remains unknown whether the word $w^q$ is actually concise in the class of all groups.
