(Istanbul Univ-cerrahpasa, 2021) Sudağıdan, Mert; Yurt, Mediha Nur Zafer; Taşbaşı, Behiye Büşra; Acar, Elif Esma; Ömeroğlu, Esra Ersoy; Uçak, Samet; Aydın, Ali; Ozalp, Cengiz; Ersoy Omeroglu, Esra; Mediha Nur, Zafer YURT
Cheese microbiota may contain various bacterial species due to the use of different types of milk, rennet, and herbs. In this study, the distribution of the dominant bacteria present in the microbiota of herby cheese samples (n = 13) were examined by the next generation sequencing (NGS) technique. DNA was extracted both directly from cheese samples and after pre-enrichment. The metagenomic analysis of the NGS results revealed that Firmicutes were dominant both in DNA directly extracted from herby cheese (KOP), and pre-enriched samples (OP), at the phylum level. At the genus level, Lactobacillus, Lactococcus, and Streptococcus were dominant in the KOP samples, whereas in the OP samples, Enterococcus, Streptococcus, and Bacillus were determined as the dominant bacterial genera. Although Lactococcus raffinolactis and Streptococcus salivarius were dominant in the KOP samples, Enterococcus faecalis and S. salivarius were dominant in the OP samples. The Shannon species diversity index and principal coordinates analysis (PCoA) were used to determine the distribution in KOP and OP samples at the genus level. The PCoA of KOP-10, KOP-11, KOP-2, and KOP-7, KOP-3, and KOP-6 samples showed the wide distribution, whereas KOP-5, KOP-8, KOP-9, and KOP-14 herby cheese samples were closely related. The OP samples, especially OP-7 and OP-14, showed wide distribution in comparison to other OP samples. Finally, the dominant bacterial communities were identified by DNAbased metagenomic analysis, and this is the first report to elucidate the microbiota of herby cheese produced in Turkey using the NGS technique.
19. Yüzyılda Osmanlı ve Rus İmparatorluklarında Yerel Yönetim Reformu: 1864 Zemstvo Kanunu ve 1864 Vilayet Nizamnamesi Üzerine Karşılaştırmalı Bir Analiz
(2022) Gülseven, Aslı Yiğıt
Osmanlı ve Rus İmparatorluklarının 19. yüzyılına damga vuran modernleşme süreci her iki devlette de kapsamlı bir reform hareketi başlatmıştı. 19. yüzyılın ortasında patlak veren Kırım Harbi neticesinde, Avrupalı devletlerin baskı ve müdahalelerinden çekinen her iki imparatorlukta da iktisadi refahın sağlanması yolunda idari düzenlemelerin ya-pılması öncelikli hedef haline gelmişti. Buradan hareketle, Osmanlı ve Rus İmparator-luklarında 19. yüzyılda etkin yönetim anlayışı çerçevesinde yerel yönetimlerde bir takım idari düzenlemeler meydana getirildi. Bir yandan yerel yönetimlerin faaliyet ve yetki alanlarının genişletilmesi anlayışı benimsenirken, diğer yandan her iki imparatorlukta da merkezi yönetimin güçlendirilmesi hedeflenmiştir. Bu çalışma, Osmanlı İmparatorlu-ğunda 1864 Vilayet Nizamnamesi ve Rus İmparatorluğunda 1864 Zemstvo Kanununun taşra örgütlenmesine getirdikleri yerel yönetim reformunu ortaya koymayı ve her iki dü-zenlemeyi tarihsel arka plan, içerik, kapsam ve etkinlik yönünden karşılaştırmalı olarak değerlendirmeyi amaçlamaktadır.

Activation Energy of Metastable Amorphous Ge₂sb_{2< From Room Temperature To Melt}
(Amer inst Physics, 2018) Muneer, Sadid; Scoggin, Jake; Dirisaglik, Faruk; Adnane, Lhacene; Cywar, Adam; Bakan, Gokhan; Gokirmak, Ali
Resistivity of metastable amorphous Ge2Sb2Te5 (GST) measured at device level show an exponential decline with temperature matching with the steady-state thin-film resistivity measured at 858 K (melting temperature). This suggests that the free carrier activation mechanisms form a continuum in a large temperature scale (300 K - 858 K) and the metastable amorphous phase can be treated as a supercooled liquid. The effective activation energy calculated using the resistivity versus temperature data follow a parabolic behavior, with a room temperature value of 333 meV, peaking to similar to 377 meV at similar to 465 K and reaching zero at similar to 930 K, using a reference activation energy of 111 meV (3k(B)T/2) at melt. Amorphous GST is expected to behave as a p-type semiconductor at T-melt similar to 858 K and transitions from the semiconducting-liquid phase to the metallic-liquid phase at similar to 930 K at equilibrium. The simultaneous Seebeck (S) and resistivity versus temperature measurements of amorphous-fcc mixed-phase GST thin-films show linear S-T trends that meet S = 0 at 0 K, consistent with degenerate semiconductors, and the dS/dT and room temperature activation energy show a linear correlation. The single-crystal fcc is calculated to have dS/dT = 0.153 mu V/K-2 for an activation energy of zero and a Fermi level 0.16 eV below the valance band edge. (C) 2018 Author(s).

Analysis of the Effect of Propellant Temperature on Interior Ballistics Problem
(2018) Evci, C.; Işık, H.
This study investigates the effect of conditioning temperature of double base propellants on the interiorballistic parameters such as burning gas temperature, barrel wall temperature, pressure and stresses generated inthe barrel. Interior ballistic problem was solved employing experimental, numerical and analytical methods witha thermo-mechanical approach. Double base propellants were conditioned at different temperatures (52, 35, 21, 0,-20, -35, -54oC). The maximum pressure in the barrel and projectile muzzle velocity were measured for all thepropellants by conducting shooting tests with a special test barrel using 7.62x51 mm NATO ammunition. Vallier-Heydenreich method was employed to determine the transient pressure distribution along the barrel. Thetemperature of burnt gases was calculated by using Noble-Abel equation. The heat transfer analysis was doneusing the commercial software ANSYS to get the transient temperature and stress distributions. Temperaturedistribution through the barrel wall thickness was validated using a FLIR thermal imager. Radial, circumferentialand axial stresses and corresponding equivalent Von Misses stresses were determined numerically andanalytically. The results of the analytical solution for stress analysis validated the finite element solution of interiorballistic problem. Increasing the initial temperature of the propellant resulted in higher temperature and pressureinside the barrel which in turn increased the stresses in the barrel.
Analyzing the Criteria Affecting Transition To Airplane by Comparing Different Methods
(Mehmet Akif Ersoy Univ, 2022) Reyhanoglu, Izay; Tengilimoglu, Dilaver
This study, using the multi-vehicle approach, discusses the criteria affecting the transition from alternative transportation modes (car, train, bus) to air transportation between city pairs that neither have a hub status nor non-stop flights between them. If these criteria change, the demand for air transportation will increase. For this purpose, a survey was conducted in the provinces of Kayseri and Bursa, which are among the important trade, industry, and tourism centers in Turkey, in the course of three months between January and March, 2018. Logistic regression, the artificial neural network model, and clustering analyses were applied to the data compiled from questionnaires responded to by 501 individuals in Kayseri and 453 individuals in Bursa. According to the empirical findings, it was concluded that the most significant criteria in the transition to air transportation according to all three methods are the cost of travel/ticket price and non-stop flight. Additionally, it was observed that the Artificial Neural Networks (ANN) model made more accurate predictions compared to others. This study is important since it compares three different methods for the purpose of criteria determination concerning the choice of transportation modes.

Anisotropic Transformation Strain and Its Consequences on Distortion During Austenitization
(Amer Soc Testing Materials, 2012) Simsir, Caner; Lubben, Thomas; Hunkel, Martin; Hoffmann, Franz; Zoch, Hans-Werner
The distribution of segregations, which is introduced in the continuous casting process and modified during succeeding manufacturing steps, is considered as an important "distortion potential carrier" for chemically banded steels. This article presents a recently developed mathematical model for integration of the effect of prior forming and cutting operations into heat-treatment simulations by considering "anisotropic transformation strain (ATS)." The model was justified experimentally by simulating the heating and austenitization of dilatometer specimens machined from the forged discs with distinct orientations with respect to the banded microstructure. After the verification, it is used in conjunction with former experimental work to demonstrate that the distribution of fiber flow is one of the important reasons of the dishing of carburized discs. The model provides promising results for process chain simulation to predict the heat-treatment distortion that cannot be predicted with currently available models.

Application of Artificial Neural Network-Based Approach for Calculating Dissolved Oxygen Profiles in Kapulukaya Dam Reservoir
(Centre Environment Social & Economic Research Publ-ceser, 2007) Tuzun, Ilhami; Soyupak, Selcuk; Ince, Ozlem; Basaran, Gokben
An Artificial Neural Network (ANN) modelling approach has been shown to be successful in calculating time and space dependent dissolved oxygen (DO) concentration profiles in Kapulukaya Dam Reservoir using limited number of input variables. The variation of inflow to the reservoir with respect to time was significantly high. The reservoir operational levels were relatively stable. The Levenberg-Marquardt algorithm was adopted during training. Preprocessing before training and post processing after simulation steps were the treatments applied to raw data and predictions respectively. Different configurations of Multilayer perceptron neural networks were designed by selecting different combinations of number of hidden layers (single and double) and number of neurons within each of the hidden layers. Generalisation was improved and over-fitting problems were eliminated: Early stopping method was applied for improving generalisation. The conventional model criteria of correlation coefficient (R) and mean square errors (MSE) were adopted to compare model performances. The correlation coefficients between neural network estimates and field measurements were as high as 0.96 for daily and monthly data respectively with experiments that involve double layer neural network structure with 31 neurons within each hidden layer. The study results revealed that the data sizes effect model performances up to a certain level.

Barriers to Adherence After A Self-Management Lymphedema Education Program Among Women with Breast Cancer-Related Lymphedema
(Lippincott Williams and Wilkins, 2026) Uçar, G.C.; Kapucu, S.; Arıkan Dönmez, A.A.; Ozdemir, O.; Dönmez, Ayşe A.
Objectives: – Lymphedema associated with breast cancer is a chronic condition that negatively affects women’s physical functioning, psychosocial well-being, and quality of life. Although self-management education is a fundamental component of lymphedema care, many women struggle to maintain recommended practices in daily life over time. To explore how women with breast cancer-related lymphedema integrate self-management education into daily life over time and to identify barriers to sustained adherence 1 year or more after completing a self-management lymphedema education program (SMLEP). Methods: – A descriptive phenomenological qualitative design was used. In-depth, semistructured interviews were conducted with 17 women diagnosed with breast cancer-related lymphedema. Data were analyzed using qualitative content analysis. Results: – Two overarching themes were identified: problems caused by lymphedema and barriers to self-management. Problems included limitations in activities of daily living, pain, restricted social participation, and body image disturbance. Barriers included economic difficulties, decreased belief in treatment effectiveness, boredom and forgetfulness, lack of family support, absence of monitoring mechanisms, use of the dominant arm, and symptom regression. Conclusions: – Women with breast cancer-related lymphedema face interconnected physical, emotional, and contextual challenges that limit long-term self-management adherence beyond knowledge deficits alone. © 2026

The Battle of Kars During the Russo-Turkish War (1877- 1878) in V. P. Meshcherskiy's 'caucasian Travel Diary'
(İstanbul University Faculty of Letters, 2021) Gülseven,A.Y.; International Relations
Travel notes and memoirs contain many contents that fill the gaps in official history, and are thus precious material for historians as primary sources. This study aims to explore the historical context of the Battle of Kars during the Russo-Turkish War of 1877-1878 by focusing on Vladimir Petrovich Meshcherskiy's travel notes and memoirs on the trip from Moscow to Kars during the war in 1877. Although there is a vast literature on the course and consequences of the Russo-Turkish War of 1877-1878, we have little first-hand information from the field to fill the gaps in our knowledge of the developments during and aftermath of the Kars attack. Meshcherskiy's travel diary does not only provide us with a close-up view of the Eastern front of the Russo-Turkish War, but it also sheds light on the attitude of the local people under the Russian siege. Although this diary provides a rich source of information from the viewpoint of Meshcherskiy, a prominent Russian journalist and novelist, it has never been used in the academic literature on the Russo-Turkish War of 1877-1878. © Turkish Journal of History 2021.
