Apilarnil ve Kralige An Larvasinin Drosophila melanogastertn Larval Mortalitesi ve Uzun Omurlulugii Uzerine Etkileri
The basic mechanisms of ageing and longevity are not yet fully understood. More studies are needed to correlate this situation with functional foods and food supplements that have been used frequently recently. Bee products are in the first place in the use of natural products and food supplements. It has been reported that drone larvae (apilarnil) and queen bee larvae, which have become popular in recent years, support the protection of health due to their high nutritional value, but no studies have been conducted on their life-extending efficacy. For this purpose, the efficacy of these two bee products on life span and mortality was investigated in our study. Apilarnil and queen bee larvae lyophilisates added to Drosophila melanogaster medium at different concentrations (0.5; 1.0; 2.5 and 5.0 mg/ml medium) were studied separately in male and female populations for treatment and control groups. As a result, apilarnil at 5 mg/ml concentration showed the best effect in terms of larval mortality compared to the control group, while the most effective group in terms of mean life span was determined as queen bee larvae with 83.1 ±3.53 days. In general, both bee products increased the life span of flies in parallel with the increase in concentration in both female and male populations. These results were statistically significant at p<0.05 level compared to the control group. In our study, it was concluded that apilarnil and queen bee larvae lyophilisates can be used in terms of life-length increasing activity, but the underlying mechanisms should be elucidated by detailed studies. © 2024 Bursa Uludag University.

Following the Innovations in A Learning Organization Perspective: To Follow, or Not to Follow
The purpose of this study was to investigate school administrators and teachers’ following innovations in pre-school education in terms of the learning organization perspective. We examined their following the innovations in terms of Information and Communication Technology (ICT) Competencies, 21st Century Skills, and Innovative School. A total of 207 participants (School Administrators N =33 & Teachers N = 174) were recruited in this research. The data collections tools were Information and Communication Technology Competency Scale (ICTC), Multidimensional 21st Century Skills Scale, and Innovative School Scale (ISS). Our results have shown that school administrators and teachers have positive attitudes towards following innovations in education. Participants, however, have some concerns over innovative atmosphere and organizational impediments in terms of the innovative school. Further, the results in innovative school showed a statistically significant difference in favor of male participants. The results of the regression analysis have revealed that there is a significant relationship between multidimensional 21st century skills and the innovative school variables at a high level. Although the participants' multidimensional 21st century skills significantly predicted their innovative school scores, we found that the ICT Competence variable alone did not predict or affect it. Limitations and recommendations for future research are provided, as well. © 2024, Ozgen Korkmaz. All rights reserved
Electromagnetism and Maxwellian Evolution Equations in terms of Darboux Frame in Minkowski Space with Abnormalities
Electromagnetic wave propagation is often thought of as the transport of polarised light and this behaviour is well defined by Maxwell's equations when propagating in an optical fiber. In this paper, we examine the q - direction and n - direction Berry's phase equation along a Darboux framed optical fibre in Minkowski space. Next, we define q - direction and n - direction for the electromagnetic curves of the Rytov parallel transport laws. And then, the application section, the connections between the Maxwellian evolution of the electromagnetic curve for Maxwell's equation and the anholonomic coordinates are visualized and illustrated with the MAPLE program.Scientific and Technological Research Council of Turkey (TUBITAK) 2211 ProgramEbru Yan & imath;k's research was supported by the Scientific and Technological Research Council of Turkey (TUBITAK) 2211 Program
Evaluation of Left Atrial Electromechanical Delay and Left Atrial Phasic Functions in Patients Undergoing Treatment with Cardiotoxic Chemotherapeutic Agents
Background: The aim of this study is to evaluate atrial involvement by comparing pre- and post-chemotherapy left atrial mechanical and electromechanical parameters in patients treated with cardiotoxic chemotherapeutic agents. Methods: We designed our study as a prospective cohort study. Sixty-eight female patients between the ages of 18 and 50, scheduled for treatment with cardiotoxic chemotherapeutic agents, were included in our study. Atrial mechanical functions and electromechanical parameters were examined and compared with basic echocardiographic parameters before and after chemotherapy. Results: The mean age of the patients was 41.6 +/- 7.9 years. After chemotherapy, lateral PA, septal PA, and tricuspid PA durations showed a significant increase (p < 0.001), but there were no statistically significant changes in the left intra-atrial electromechanical delay, the right intra-atrial electromechanical delay, or the interatrial electromechanical delay values. Following treatment, LAVmax, LAVmin, and LApreA significantly increased (p < 0.001). Additionally, the left atrial passive and active emptying volumes increased (p < 0.001), while the reservoir and pump (active emptying) functions decreased (with p-values of 0.03 and 0.01, respectively). The passive emptying function, however, showed no significant change (p = 0.65). Decreases in LVEF were observed, while LVEDD, LVESD, IVS, PW, and LA diameters increased (p-value of 0.02 for IVS and <0.001 for the others). Conclusions: Significant impairment of atrial mechanical functions and electromechanical parameters was observed after treatment with cardiotoxic chemotherapeutic agents. This suggests an elevated likelihood of atrial arrhythmia linked to the use of cardiotoxic chemotherapeutic agents
Comparison of median nerve area measurement between MRI and electromyography in patients diagnosed with carpal tunnel syndrome
Background. Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy that occurs when the median nerve is compressed within the carpal tunnel. Electromyography (EMG) is accepted as the most frequently used and important diagnostic method for CTS. Recently, magnetic resonance imaging (MRI) has begun to be used in CTS patients to directly visualize the median nerve and examine the changes occurring in the nerve structure. Objectives. In this study, the area of the median nerve was measured at various levels in the wrist in patients with CTS using MRI, examining its relationship with signal increase, and comparing this to results obtained with EMG. Materials and methods. Overall, 35 patients diagnosed with CTS were included in the study. Patients with normal-mild and moderate-severe EMG tests were included in the study; wrist MRI was taken to investigate the area/mm2 of the median nerve at various levels and whether there was an increase in signal. Thenar muscles included in the imaging were also evaluated. Results. Of the 35 patients included in the study, 24 were women (68.6%) and 11 were men (31.4%). Measurements of the average median nerve area measured in mm2 at the distal radioulnar junction (DRUJ) and the median nerve area measured in mm2 at the hamate bone level were obtained, showing that DRUJ and hamate bone distance measurements were higher in patients with positive EMG. Electromyography findings were also significantly positive in patients with increased signal. Conclusions. In some cases, the diagnosis of CTS can be easily made with history and physical examination or employing confirmatory tests such as EMG, which is considered the gold standard. Magnetic resonsnace imaging can be used as an alternative method for imaging the median nerve in patients with CTS. In our study, EMG findings were also significantly positive in patients with increased signal on MRI, making it a preferable method, especially in soft tissue-related pathological cases
Behaviors of pregnant women regarding travel - The case of Türkiye
Introduction and aim. With the development of transportation facilities and options, people can now travel easily. With women having a greater presence in the workforce, pregnant women can work until the eighth week before childbirth. This study was conducted to examine the behaviors of pregnant women regarding travel. Material and methods. The data for this cross-sectional and descriptive study were collected from 519 pregnant women who voluntarily participated in the research and met the research criteria. The data were analyzed using the SPSS 24 software package. Results. The average age of the participating pregnant women was 27.49±0.17, with 63.8% residing in urban areas, 74.8% being primiparous, and 47.6% being in the third trimester of pregnancy. A decrease in travel and car usage during pregnancy. The use of bus, train/tram/metro, taxi, bicycle/scooter, and motorcycle decreased during pregnancy, while use of car, plane, and ship/ferry increased. 81.9% of women always wore a seat belt during pregnancy. There was a statistically significant difference between the educational level of women and their car usage (p<0.005). It was found that women wore seat belts more frequently in the third trimester. As the number of pregnancies increased, the frequency of seat belt usage decreased. Conclusion. A decrease in the frequency of travel was observed among women during pregnancy. The levels of seat belt usage and correct seat belt fastening were unsatisfactory. © 2024 Publishing Office of the University of Rzeszow. All rights reserved
PEÇEVİ TARİHİNDE MAKAM VE KURUM ADLARI
İbrahim Peçevî, Macaristan’da doğan Osmanlı tarihçisidir. Macarlarca vakanüvis (görevli devlet tarihçisi) olarak bilinen İbrahim Macaristan’ın Pecs (Peçuy) şehrinde doğmuştur, bu sebeple doğduğu ve yaşadığı bölgelerde Peçuyi, sonradan da Peçevî olarak anılmıştır. 17. yüzyıl ve öncesi olaylarının Osmanlı Devlet’ini merkeze alarak anlattığı kitabının adı eski adıyla Tarih-i Peçevî, bugünkü bilindiği adıyla Peçevi Tarihi’dir. 17. yüzyıl ve öncesi Osmanlı coğrafyasında yaşanan olayları anlatan Peçevi Tarihi önemli tarih kaynaklarından birisidir. Kanuni döneminden IV. Murat’a kadar birçok gelişmeden bahseden eserdeki adlar hiç şüphesiz hem tarihî hem de dil bilimsel açıdan önemlidir. Eser içindeki adlar her iki bilim dalı için çeşitli verileri yansıtmaktadır. Ad bilimi, dil biliminin özellikle özel adları inceleyen bir alt dalıdır. Özel adlar yanında diğer adlar da dolaylı olarak ad biliminin ilgi alanına girmektedir. Bu çalışmada; Peçevi Tarihi’nden hareketle 17. yüzyıl ve öncesinde kullanılan kurum ve makam adlarının özellikleri gözler önüne serilecektir. Peçevi Tarihi’ndeki bu sözcükler belirlenerek sınıflandırılacak ve bu sözcüklerin karşıladığı kavramlar üzerinde durulacaktır. Böylelikle tarihî adbilimcil birimlerin bilimsel açıdan farklı yönleri ele alınacaktır
EFL Teachers' Reflective Practices: A Holistic Approach To Reflective Practice Perception and Implementing Tools of EFL Teachers
The aim of this qualitative study is to find out the level of EFL teachers' awareness of reflective practices, the obstacles preventing reflecting on oneself and differences of perception and level of reflective practices between private sector teachers and state school teachers. In this respect, the study explored 8 EFL teachers who volunteered from private sector and 8 from state schools in … province. The interviews were held through zoom software because of Covid19. The data was collected through a semi-structured interview form. All the qualitative data gathered through interviews was transcribed and analyzed according to thematic analysis. Data analysis was conducted manually. At the end of the study, the results revealed a relatively low level of reflection with the teachers under study tending to rely more on their own rationality in teaching and evaluating. Teachers are evaluating themselves or their classes mostly by taking the students in the center and they don't have a systematic approach. On the other hand there is a slightly meaningful result showing private sector teachers are more careful about reflective practice because of other dynamics like parents and management and they do more to evaluate and improve themselves. The tools both groups us for reflective practice are variable and there are challenges related with teacher, education system and students that teachers show as an excuse for not implementing reflective practice. It is argued that teachers to develop desirable levels of pedagogic integrity, they should involve themselves more in exploring themselves, their students' learning styles and critical aspects of the teaching context
A Historical Review of Genocide Claims in the Israeli-Palestinian Conflict
M.S. 64'te başlayan Roma sürgünü ile yaklaşık 2000 yıl süren diaspora döneminde Yahudiler, maruz kaldıkları antisemitist tutumlara son vermek amacıyla, 19. yüzyıldaki ulusçuluk akımının da etkisiyle kendilerine vaat edilmiş kutsal topraklarda (Filistin) bir Yahudi devleti kurma amacını benimsemişlerdir. Bu hedef doğrultusunda şekillenen Siyonist hareket, 1897 yılında Macar Yahudi lider Theodor Herzl önderliğinde İsviçre'de toplanan 1. Siyonist Kongresi'nde bu amacını resmen ilan etmiştir. 1917 Balfour Deklarasyonu ve 1922-1948 İngiliz mandaterliği, döneminde Filistin topraklarına yapılan Yahudi göçünün ve yerleşiminin artması Arap ve İsrail halkları arasında gerilimlere yol açarken 1948'de İsrail'in kurulması, İsrail-Filistin çatışmasını resmen başlatmıştır. 1948, 1956, 1967 ve 1973'te dört büyük Arap-İsrail savaşı yaşanmıştır. Söz konusu savaşlar sadece toprak mücadelesini değil, aynı zamanda kimlik, egemenlik ve insan hakları üzerine derin bir anlaşmazlığı da yansıtmaktadır. 2000'li yıllarda çatışmalar şiddetlenmiştir. 2014 Gazze Savaşı ve 7 Ekim 2023'te başlayan son çatışmalar büyük yıkıma ve sivil kayıplara neden olmuştur. İsrail’in uyguladığı orantısız güç ve neden olduğu büyük yıkım uluslararası toplumun tepkisine ve soykırım iddialarının Uluslararası Adalet Divanı (UAD)’na ve Uluslararası Ceza Mahkemesi’ne taşınmasına neden olmuştur. Bu çalışma, İsrail-Filistin çatışmasını, çatışmanın tarihsel arka planını ele alarak günümüzde yaşanan sonuçlarını ve soykırım iddialarının yansımalarını analiz etmeyi amaçlamaktadır.The Zionist movement, aiming to end the anti-Semitic attitudes faced during the diaspora period that began with the Roman exile in 64 AD and lasted nearly 2000 years, sought to establish a Jewish state in the promised holy land (Palestine), influenced by the nationalist movement of the 19th century. This goal was officially declared at the 1st Zionist Congress held in Switzerland in 1897 under the leadership of the Hungarian Jew Theodor Herzl.The 1917 Balfour Declaration and the increased Jewish immigration and settlement in Palestinian territories during the British mandate of 1922-1948 led to tensions between the Arab and Israeli peoples, while the establishment of Israel in 1948 officially started the Israeli-Palestinian conflict. Four major Arab-Israeli wars took place in 1948, 1956, 1967 and 1973. These wars reflect not only a struggle for territory, but also a deep conflict over identity, sovereignty and human rights. Conflicts intensified in the 2000s. The 2014 Gaza War and the most recent conflict, which began on October 7, 2023, have caused massive destruction and civilian casualties. Israel's disproportionate use of force and the massive destruction it has caused have led to the international community's outcry and genocide allegations being brought before the International Court of Justice (ICJ) and the International Criminal Court. This study aims to analyze the Israeli-Palestinian conflict, its historical background, its contemporary consequences and the repercussions of genocide allegations
New type of extended operations of soft sets: Complementary extended union, plus and theta operation
Molodtsov tarafından 1999 yılında bazı belirsizlik içeren problemleri modellemek için ortaya atılan esnek küme teorisinin temel yapı taşını esnek küme işlemleri oluşturmaktadır. Bu tez çalışmasında, teoriye katkıda bulunmak için, yeni bir esnek küme işlem formu olan tümleyenli genişletilmiş işlemler tanımlanmıştır. Bu kapsamda, tümleyenli genişletilmiş birleşim, tümleyenli genişletilmiş artı ve tümleyenli genişletilmiş teta işlemleri tanımlanmış, örnekleri verilmiş, işlemlerin tüm özellikleri detaylı bir şekilde ele alınmış, her bir işlemin diğer esnek küme işlemleri ile ilişkisini elde etmek amacıyla, bu işlemlerin diğer esnek küme işlemleri üzerine dağılmasına bakılmış ve sabit parametreli esnek kümeler kümesi üzerinde tümleyenli genişletilmiş birleşim işleminin hangi cebirsel yapılar oluşturduğu detaylı şekilde ele alınmıştır. Altı bölümden oluşan tez çalışmasının ilk bölümünde esnek kümeler ve tezde adı geçen cebirsel yapılar ile ilgili literatür taraması yapılmış, ikinci bölümde, temel küme işlemleri, esnek kümeler ve bazı cebirsel yapılar ile ilgili temel kavramlara yer verilmiştir. Tezin özgün bölümünü oluşturan, üçüncü, dördüncü ve beşinci bölümlerinde sırasıyla, tümleyenli genişletilmiş birleşim, tümleyenli genişletilmiş artı ve tümleyenli genişletilmiş teta işlemleri tanıtılmış, işlemlerin kapalılık, birleşme, birim eleman, ters eleman, değişme, idempotent gibi tüm özellikler incelenmiş, diğer işlemlerle ilişkişini görmek için, işlemlerin diğer işlemlere dağılmasına bakılmıştır. Klasik kümelerde de var olan birleşim işlemi ile tümleyenli genişletilmiş birleşim işleminin özellikleri karşılaştırılmış ve dikkat çekici sonuçlar elde edilmiştir. Üstelik sabit parametreli esnek kümeler kümesi üzerinde, tümleyenli genişletilmiş birleşim işleminin sınırlı bir yarı-kafes; yine tümleyenli genişletilmiş birleşim işleminin diğer esnek küme işlemleri ile birlikte komutatif, idempotent, birimli, sıfırsız bir yarı-halka, komutatif, idempotent, birimli bir hemihalka, Bool Cebiri, De Morgan Cebiri ve MV-cebiri olduğu gösterilerek, klasik cebire de katkıda bulunulmuştur. Sonuç ve öneriler bölümünde, elde edilen sonuçlara ve sonuçların önemine yer verilmiştir.Soft set operations constitute the basic building block of soft set theory, which was introduced by Molodtsov in 1999 to model some problems involving uncertainty. In this thesis, in order to contribute to the theory, a new soft set operation form, called complementary extended operation, is defined. In this context, complementary extended union, complementary extended plus and complementary extended theta operations are defined, their examples are given, all the properties of these operations are discussed in detail, in order to obtain the relationship of each operation with other soft set operations, the distribution of these operations over other soft set operations are examined, and the algebraic structures that the complementary extended union operation form on the set of soft sets with a fixed parameter set are discussed in detail. In the first part of the thesis, which consists of six sections, a literature review is made about soft sets and the algebraic structures mentioned in the thesis, and in the second part, basic concepts about basic set operations, soft sets and some algebraic structures are included. In the third, fourth and fifth chapters, which constitute the original part of the thesis, the complementary extended union, complement extended plus and complement expanded theta operations are introduced, respectively, and all properties of the operations such as closure, union, unit element, inverse element, commutation, the idempotent property are examined, and their relationships of these operations with other operations are investigated. For this purpose, the distributions of these operations over other soft set operations are taken into consideration. The properties of the union operation, which also exists in classical set theory, and the complementary extended union operation are compared and many remarkable results are obtained. Moreover, by showing that the complementary extended union operation, along with other soft set operations, are commutative, idempotent, unitary, non-zero semiring, commutative, idempotent, unitary hemiring, Boolean Algebra, De Morgan Algebra and MV-algebra, it has also contributed to classical algebra. In the results and recommendations section, the results obtained and the importance of the results are included
