Electronic structure and optical properties of Schiff base hydrazone derivatives by solution technique for optoelectronic devices: Synthesis, experiment and quantum chemical investigation
No full textWOS: 000449310600004In this study, electronic, optical and spectroscopic FT-IR, UV properties of new synthesized Schiff base hydrazone derivatives, 1-(4-nitrophenyl)-2-(4-phenoxybenzylidene)hydrazone and 1-(2,4-dinitropheny1)-2-(4-phenoxybenzylidene)hydrazone are investigated by performing solution techniques and theoretical calculations. Solvatochromism and solute-solvent interactions were discussed based on the spectral results. It is observed that Schiff base hydrazone derivatives exhibit positive solvatochromism. Energy band gap E-g is determined experimentally and theoretically in solution. Concentration effect on E-g was investigated in DCM solvent for different molarities of solute. It is observed that solvent and concentration can be used for tuning E-g. NO2 substituent group gives rise to E-g value lows 0.3 eV. The refractive index (n) values were obtained from Moss, Ravindra, Herve-Vandamme, Kumar-Singh and Reddy relations based on E-g data. It is observed that n can be controlled with solvents and concentration of solutions. External electric field (EF) is theoretically applied in order to tuning HOMO-LUMO gap and dipole moment. Consequently, Schiff base hydrazone derivatives intend to be insulator under applied EFBitlis Eren University, Research Foundation [BEBAP-2013.04, BEBAP-2014.05]; Bitlis Eren UniversityThe authors greatly appreciate Bitlis Eren University, Research Foundation for the financial support via BEBAP-2013.04 and BEBAP-2014.05 projects.

From Home to Mars. On Halil Altındere’s Space Refugee and Homeland Projects
No full textAutorka przygląda się dwóm projektom Halila Altındere – jednego z czołowych tureckich artystów wizualnych. Oba powstały w 2016 roku, gdy Turcja mocno odczuła skutki „kryzysu migracyjnego” wywołanego między innymi eskalacją wojny w sąsiedniej Syrii. W Anatolii schronienia szukała wtedy bezprecedensowo duża liczba ludzi – niektórzy traktowali Turcję jako kraj tranzytowy, inny osiedli tam na stałe. Halil Altındere podjął wówczas współpracę z dwiema wyrazistymi postaciami ze świata syryjskiej diaspory: z Muhammadem Ahmedem Farisem – pierwszym arabskim kosmonautą, a dziś żyjącym na wygnaniu w Stambule dysydentem, którego historia stała się jądrem projektu Space Refugee, oraz z Abu Hajarem – osiadłym w Berlinie „młodym gniewnym” raperem, z którym zrealizował wideo Homeland. Obie prace na dwa różne sposoby dotykają kwestii złożoności kondycji uchodźczej – a w myśleniu o nich autorce towarzyszy książka Migawki z tradycji uciśnionych, w której Paweł Mościcki przygląda się dialektycznemu charakterowi doświadczenia wygnania.The author examines two projects by Halil Altındere – one of leading Turkish visual artists. Both ventures originated in 2016, when Turkey severely experienced the effects of the “migration crisis” caused by, i.a. the escalation of war in neighbouring Syria. At the time, an unpreceded number of people sought refuge in Anatolia – some treated Turkey as a transit country, while others settled down on a permanent basis. At the time Halil Altındere embarked upon co-operation with two prominent members of the Syrian diaspora: Muhammad Ahmad Faris – the first Syrian cosmonaut, today a resident of Istanbul, whose story became the core of the Space Refugee project, and Mohammad Abu Hajar – an “angry young rapper” living in Berlin, with whom Halil Altındere recorded the Homeland video. Both projects pertain in different ways to the question of the complexity of being a refugee – the author of the presented reflections relates to the book Migawki z tradycji uciśnionych, in which Paweł Mościcki examined the dialectic character of the experience of exile
A hybrid method to solve a fractional-order Newell–Whitehead–Segel equation
No full textThis paper solves fractional differential equations using the Shehu transform in combination with the q-homotopy analysis transform method (q-HATM). As the Shehu transform is only applicable to linear equations, q-HATM is an efficient technique for approximating solutions to nonlinear differential equations. In nonlinear systems that explain the emergence of stripes in 2D systems, the Newell–Whitehead–Segel equation plays a significant role. The findings indicate that the outcomes derived from the tables yield superior results compared to the existing LTDM in the literature. Maple is utilized to depict three-dimensional surfaces and find numerical values that are displayed in a table. © The Author(s) 2024
Power Relationships between Russia, the Crimea and the Ottoman Empire as Reflected in Titulature. Part 2.
Full text linkThe given article is a Russian translation of the Turkish historian (of the Crimean Tatar origin) Halil Inalcik`s work “Power Relationships between Russia, the Crimea and the Ottoman Empire as Reflected in Titulature”. The author focuses attention on changes in titulature of Russian tsars and other rulers in the context of changes in mutual power relationships between the states. The author also analyses economic relationships between the given countries, pays attention to the tribute paid by the neighboring countries to the Crimean Khanate. The author stresses the most important of them: uluğ hazine, koltka, tiyiş, bölek, vergi, pişkeş. The essence of tribute sent to the Crimean Khan, his family members, officials, begs and servants is carefully considered
A new study on the Newell-Whitehead-Segel equation with Caputo-Fabrizio fractional derivative
No full textIn this research, we propose a new numerical method that combines with the Caputo-Fabrizio Elzaki transform and the q-homotopy analysis transform method. This work aims to analyze the Caputo-Fabrizio fractional Newell-Whitehead-Segel (NWS) equation utilizing the Caputo-Fabrizio q-Elzaki homotopy analysis transform method. The Newell-Whitehead-Segel equation is a partial differential equation employed for modeling the dynamics of reaction-diffusion systems, specifically in the realm of pattern generation in biological and chemical systems. A convergence analysis of the proposed method was performed. Two-dimensional and three-dimensional graphs of the solutions have been drawn with the Maple software. It is seen that the resulting proposed method is more powerful and effective than the Aboodh transform homotopy perturbation method and conformable Laplace decomposition method in the results. © 2024 the Author(s), licensee AIMS Press
The novel numerical solutions for time-fractional Fornberg-Whitham equation by using fractional natural transform decomposition method
No full textThe time-fractional partial differential equations were solved by the fractional natural transform decomposition method. Fractional derivatives are Caputo sense. The Fornberg-Whitham equation is a generalization of the Korteweg-de Vries (KdV) equation, which describes the propagation of long waves in shallow water. It includes higher-order dispersion terms, making it applicable to a wider range of dispersive media the fractional natural transform decomposition method (FNTDM) was also used to examine applications, and the solutions obtained by this method have been compared to those obtained by the variational iteration method, fractional variational iteration method, and homotopy perturbation method. In addition, the MAPLE package drew graphs of the solutions of nonlinear time-fractional partial differential equations, taking into account physics. The method described in this study exhibited a notable degree of computational precision and straightforwardness when used to the analysis and resolution of intricate phenomena pertaining to fractional nonlinear partial differential equations within the domains of science and technology. © 2024 the Author(s)
One of the last Naqshbandi sheikhs İbrahim Halil Sogukoglu's life, works and mystical thoughts
Full text linkYüksek Lisans Teziİbrahim Halil Soğukoğlu (ö.1952) Osmanlı Devleti'nin son dönemiyle Türkiye Cumhuriyeti'nin ilk yıllarında yaşamış, Kurtuluş Savaşı'na iştirak ederek gazi olmuş bir mutasavvıftır. Şeyh İbrahim Halil, Hatay'ın anavatana iltihakı ve Suriye'nin Fransızlardan tecridi noktasında aktif rol oynamıştır. Yabancı kaynaklarda “Müridler Hareketi” olarak geçen Kuzey Suriye'de başlattığı silahlı mücadele hareketi ile bölge halkının sosyal, ekonomik, dinî ve askerî uyanışını sağlamıştır. Elli iki yıllık kısa ömrünü cihad, hapis ve sürgünlerde geçirmiş, mücahid, edip, âlim bir zâttır. Tasavvufî, sosyal ve siyasî açıdan önemli faaliyetleri olmasına rağmen büyük oranda kendi tercihi ile ismi ve faaliyetleri yakın tarihin gizli sayfalarında kalmıştır. Bu çalışma, yoğun mücadele ve mücahede yıllarına rağmen tasavvufî eserler vermekten geri durmayan son dönem Nakşî şeyhlerinden İbrahim Halil Soğukoğlu'nun hayatı, eserleri ve tasavvufî görüşlerini içermektedir. Araştırmamızın birinci bölümünde; müellifin hayatı ve eserleri ele alınmış, siyasi ve askeri mücadelesi, şeyhleri, halifeleri, eserlerinin muhtevası ve üslubu hakkında bilgi verilmiştir. İkinci bölümde ise müellifin eserlerinde yer alan tasavvufi görüşler, başlıkların muhtevasına göre farklı kaynaklardan yararlanarak ele alınmıştır. Hulâsatül-Âdâb Fî Reddi's-Serâb adlı "edep‟ kitabı, müellifin Divan-ı Kenzü'ş-şümûs eserine ait beyitlerinden iktibaslarla açıklanmıştır. Çalışmamızın son kısmında ise Tulû eserindeki tasavvufî görüşler, Kenzü'l Maarif adlı eser içeriğiyle desteklenerek dile getirilmiştir. iii Şeyh İbrahim Halil'in hayatı ve tasavvufî şahsiyeti gerek siyasî tarihe gerek tasavvuf tarihine ışık tutması bakımından gün yüzüne çıkarılması gereken pek çok noktayı barındırmaktadır. Müellifin hayatı ve eserleri hakkında yeterli düzeyde kaynak ve araştırma bulunmaması bu çalışmanın yapılmasını gerekli kılmıştır.İbrahim Halil Soğukoğlu (d.1952) is a Sufi who lived in the last period of the Ottoman Empire and the first years of the Republic of Turkey and became a veteran by participating in the War of Independence. Sheikh İbrahim Halil played an active role in the annexation of Hatay to the motherland and the isolation of Syria from the French. He ensured the social, economic, religious and military awakening of the people of the region with the armed struggle movement he initiated in Northern Syria, referred to as the "Mürid Hareketi" in foreign sources. He is a mujahid, literary and scholarly person who spent his short life of fifty-two years in jihad, prison and exile. Although he had important Sufi, social and political activities, his name and activities remained in the secret pages of recent history, largely by his own choice. This study includes the life, works and mystical views of İbrahim Halil Soğukoğlu, one of the late Nakshi sheikhs who did not refrain from producing Sufi works despite the years of intense struggle and struggle. In the first part of our research; The author's life and works are discussed, and information is given about his political and military struggle, sheikhs, caliphs, the content and style of his works. In the second part, the Sufi views in the author's works are discussed using different sources according to the content of the titles. The 'decency' book named Hulâsatül-Âdâb Fî Reddi's-Serâb is explained with quotations from the couplets of the author's work Divan-ı Kenzü‟ş-şümûs. In the last part of our study, the Sufi views in the work Tulu are expressed, supported by the content of the work called Kenzü'l Maarif. The life and Sufi personality of Sheikh İbrahim Halil contains many points that need to be brought to light in terms of shedding light on both political history and the history of Sufism. The lack of sufficient resources and research on the life and works of the author made it necessary to conduct this study
The Return of Local Democracy: The CHP and the İstanbul Metropolitan Municipality
No full textThis article looks into the historical watershed of the 2019 local elections in Turkey and examines to what extent local government can empower opposition parties under the conditions of autocratic consolidation. The author looks into the case of the Metropolitan Municipality in Istanbul and argues that the administrative capacity-building and the cadre development, which the main opposition accomplished once in power can reinvigorate opposition politics and allow for the emergence of alternative power centres that may eventually challenge the incumbent
Türkiye'de nasıl bir iktisat öğretimi: Bazı düşünce, deneyim ve gözlemler
No full textSeyidoğlu, Halil (Dogus Author)Değerli hocamız, Türkiye' de iktisat eğitimine yarım asırdan fazla hizmet veren Sayın Prof. Dr. Zeyyat Hatiboğlu için çıkartılacak anı kitabına nasıl bir yazı yazmam uygun olur diye düşünürken, kendisinin de bu konuya verdiği önemi göz önüne alarak Türkiye' de İktisat Eğitimi üzerine yazmaya karar verdim. Kanımca da bu konu ülkemizde en fazla tartışılması gereken bir konu olmasına karşın, belki de en az üzerinde durulan sorunlardan birisi olmuştur. İktisat eğitimi konusu, halen bu alanda eğitim gören ve yarın da bu alana yönelmeyi düşünen on binlerce gencimizi ilgilendireceği gibi, aynı zamanda Türkiye'nin kalkınması, kıt kaynaklarımızın daha akılcı kullanılması ve toplumun yaşam düzeyinde beklenen artışların sağlanması açısından da son derecede önemlidir. Burada, Sayın Profesör Hatipoğlu'nun engin deneyimleriyle karşılaştırılabilecek düzeyde olmasa da kendi meslek yaşamımızın vermiş olduğu deneyimlere dayanarak bazı düşünce ve görüşleri ortaya koymaya çalışacağım
