Improved Generalized Differential Transform Method for A Class of Linear Nonhomogeneous Ordinary Fractional Differential Equations
(Bentham Science Publishers, 2023) Kıymaz, Onur; Çetinkaya, Aysegül
In this paper, by using the generalized Taylor's formula we improved the generalized differential transform method, which is a useful tool for getting the approximate analytic solutions of fractional differential equations. With this improvement, solutions of a class of linear nonhomogeneous ordinary fractional differential equations, which could not be solved with generalized differential transform method before, will be achieved and the solutions obtained will contain more integers and fractional exponents.
Efforts to Raise Social Awareness Against Cholera During the Second Constitutional Years (1908-1914)
(Istanbul University Press, 2024) Akagündüz, Ümüt
This study evaluates the measures against cholera based on the epidemics experienced in the Second Constitutional years. In the 19th century, cholera, which caused numerous deaths worldwide due to industrialization and poor urbanization, also affected the Ottoman Empire. The fear caused by cholera led to transformations in health policies and municipal services. Cholera, which also impacted the Second Constitutional Period, spread throughout the country, especially in Istanbul, between 1909 and 1913. The cholera epidemics, coupled with domestic and foreign political chaos, were frequently emphasized in the publications of the time. Periodicals, books, parliamentary debates, and state archives from the period provide much information on the epidemic. These data illuminate the nature of the disease and the struggles against it, embodying scientific, pragmatic, and popular methods of information dissemination. This article employs survey models and document analysis, utilizing literature that focuses on the local and global course of cholera, as well as archive documents, periodicals, books, and memorandums that clarify the period’s conditions. The data from the press and publication life reveal that, in addition to health policies, public awareness was also significant in the fight against cholera.
Novel Α-N-Heterocyclic Thiosemicarbazone Complexes: Synthesis, Characterization, and Antimicrobial of Properties İnvestigation
(Royal Society of Chemistry, 2024) Nartop, Dilek; Hasanoğlu Özkan, Elvan; Öğütçü, Hatice; Kurnaz Yetim, Nurdan; Özdemir, İnci
In this paper, eight novel α-N-heterocyclic thiosemicarbazone complexes were synthesized in search of new biologically active compounds, and characterized via organic elemental analysis, nuclear magnetic resonance spectroscopy, infrared spectra, thermogravimetric analysis, ultraviolet-visible spectroscopy, molar conductance and magnetic susceptibility measurements. The in vitro antimicrobial activity of these complexes was examined against ten disease-causing pathogens: Gram-positive bacteria (Micrococcus luteus ATCC9341, Staphylococcus epidermidis ATCC12228, Bacillus cereus RSKK863) and Gram-negative bacteria (Pseudomonas aeroginosa ATCC27853, Klebsiella pneumonia ATCC27853, Enterobacter aerogenes ATCC51342, Salmonella typhi H NCTC9018394, Shigella dysenteria NCTC2966, Proteus vulgaris RSKK96026) and yeast (Candida albicans Y-1200-NIH). The results revealed that the α-N-heterocyclic thiosemicarbazone compounds showed potent activity. It was observed that all thiosemicarbazone complexes were more susceptible to Gram-negative strains based on the presence of an electron-withdrawing substituent (-Br/-Cl/-F). It was determined that thiosemicarbazone Cu2+complexes showed stronger antifungal effects.
Is Military Spending Converging Across Middle Eastern Countries and Turkiye? A Comprehensive Unit Root Test Analysis
(Wıley, 2024) Üçler, Gülbahar; Özşahin, Şerife
The Middle East is a region of chronic insecurity due to internal and external tensions. These tensions and insecurity have made the Middle East one of the world's leading regions in military armaments. This study investigates the stochastic convergence of military burden in 10 selected Middle Eastern countries using comprehensive unit root analysis. Stochastic convergence for each country from 1977 to 2020 is examined using conventional, structural break, nonlinear, and Fourier-based unit root tests. Empirical results provide strong evidence of convergence with regional averages in Bahrain, Saudi Arabia, and Oman. There is also some evidence of convergence in the case of Israel, Egypt, Kuwait, Lebanon, and Turkiye. However, evidence for the existence of convergence in Iran and Jordan is weak.
A Rare Cause of Erectile Dysfunction: Bilateral Thrombosed Internal Iliac Artery Aneurysms
(Professıonal Medıcal Publıcatıons, 2024) Üntan, İbrahim; Çil, Ahmed Said
Internal iliac artery aneurysms are a relatively uncommon condition that can have serious consequences if left untreated. This paper presents a case of erectile dysfunction caused by thrombosis of the internal iliac artery aneurysms in a 52-years-old male patient with common iliac and internal iliac artery aneurysms. Following the intracavernous self- injection treatment, the patient's complaints about erectile dysfunction ceased. Aneurysms were monitored closely. To the best of our knowledge, this represents the first case of erectile dysfunction being presented as a consequence of thrombosed iliac artery aneurysms. Erectile dysfunction itself is not a life-threatening condition. However, it should be highlighted that erectile dysfunction can be a sign of life-threatening iliac artery diseases, as in this case. Therefore, it is crucial to recognize the potential seriousness of this condition and to investigate it thoroughly.
