Cyprinus carpio’da Monogenea grubundan Dactylogyrus extensus, Diplozoon paradoxum, (ergin ve larva (diporpa) evresi) Nematoda grubundan Rhabdochona denudata ve Raphidascaris acus tespit edilmiştir. Tinca tinca’da Digenea grubundan Asymphylodora tincae, Cestoda grubundan Ligula intestinalis ve Nematoda grubundan Streptocara sp. bireyleri bulunmuştur. Elde edilen bulgulara göre Esox lucius için Raphidascaris acus, Cyprinus carpio için Rhabdochona denudata ve Tinca tinca için Asymphylodora tincae türleri bu balık türlerinde dominant parazitler olarak tespit edilmiştir.
Bu çalışmada sazan balığında Diplozoon paradoxum larvasının (diporpa) ilk kez tespit edilmesi, yine kadife balığının Streptocara sp. türüne paratenik konak olarak tespiti Türkiye parazit faunası için önemli bir yeni kayıt niteliği taşımaktadır.In this study, a total of 310 fish, including 90 pike (Esox lucius), 93 carp (Cyprinus carpio), and 127 tench (Tinca tinca) fish caught from Lake Işıklı, Çivril district of Denizli province between April 2024 and December 2024, were examined parasitologically. 73 parasite individuals were detected in Esox lucius, 354 in Cyprinus carpio, and 9737 in Tinca tinca.
As a result of this study, the distribution of parasite species detected in the 310 fish examined according to fish species was as follows: Raphidascaris acus (adult and larval stage) from the Nematoda group, and Argulus foliaceus from the Crustacea group were detected in Esox lucius. In Cyprinus carpio, Dactylogyrus extensus, Diplozoon paradoxum (adult and larval (diporpa) stage) from the Monogenea group, Rhabdochona denudata and Raphidascaris acus from the Nematoda group were detected. In Tinca tinca, Asymphylodora tincae from the Digenea group, Ligula intestinalis from the Cestoda group, and Streptocara sp. from the Nematoda group were found. According to the findings, Raphidascaris acus for Esox lucius, Rhabdochona denudata for Cyprinus carpio, and Asymphylodora tincae for Tinca tinca were detected as the dominant parasites in these fish species.
In this study, the first detection of Diplozoon paradoxum larva (diporpa) in carp and the detection of tench as a paratenic host for Streptocara sp. are important new records for the parasite fauna of Türkiye
Unexpected Color Appearance Of Pleural Fluid: A Bilothorax Case
No full textBilothorax, or cholethorax, is a rare cause of exudative pleural effusion characterized by the presence of bile in the pleural space. Recognizing this condition is essential to prevent severe complications such as empyema and acute respiratory distress syndrome. This report presents a 70-year-old male patient who developed right-sided bilothorax following multiple biliary tract interventions. The patient presented with symptoms of jaundice, fever, and abdominal pain. Clinical and radiological evaluations revealed right-sided pleural effusion, and thoracentesis yielded dark yellow-green fluid. The diagnosis of bilothorax was confirmed by a pleural fluid/serum total bilirubin ratio >1.0. Early intervention was performed using a cystofix to drain the pleural fluid. However, despite all interventions, the sepsis condition could not be controlled, and the patient unfortunately passed away. Bilothorax is generally associated with hepatobiliary procedures and is mostly observed on the right side due to anatomical proximity. Diagnosis requires a high index of suspicion, especially in patients with relevant clinical histories and characteristic pleural fluid appearance. Rapid thoracentesis and pleural fluid analysis are crucial for diagnosis. Treatment typically involves pleural drainage and early administration of broad-spectrum antibiotics. In conclusion, bilothorax is a life-threatening condition requiring urgent diagnosis and intervention. This case highlights the importance of recognizing this rare condition and the necessity for early aggressive management in patients with a history of hepatobiliary procedures. © 2025, Pamukkale University.

The Mediating Effect of Trust in Meal-Sharing Platforms on Individuals’ Intention To Experience Local Meals
No full textThanks to meal-sharing apps, tourists can experience meals in the homes of local people in the cities they visit. In addition, it is also seen that they participate in various cooking workshops in the homes of local people or visit local markets with them and buy food and beverages. Therefore, meal sharing is also an important gastronomy experience. The aim is to examine the mediating effect of trust in meal-sharing applications on individuals’ intention to experience local meals within the scope of the theory of planned behavior by focusing on the local meal experience offered in sharing economic practices. Questionnaires were collected from 397 Turkish participants. It was found that the participants mostly used sharing economy applications for accommodation (Airbnb) and transportation (Uber), but some participants used meal-sharing applications, albeit on different platforms. The study found that attitudes toward digital meal-sharing platforms and subjective norms are the strongest factors in the intention to taste local meals. It is concluded that the trust factor has a partial mediating role in the relationship between intention, attitude, subjective norm, and perceived behavioral control. © 2025 Taylor ; Francis Group, LLC
Current-Mirror Based Filters With Reduced Circuit Complexity
No full textIn this Letter, we propose a novel current-mirror-based lossless integration stage. The proposed stage is derived from the lossy integration counterpart by simply incorporating an additional DC current source. The unique offered contribution is the reduction of the circuit complexity in the resulting current-mode systems, where the introduced integrator is utilized. This is verified through the performed comparison with the corresponding stage, which is already introduced in the literature. A multiple-output biquad filter is designed using the proposed lossless integrator, and its performance is evaluated through the utilization of the Cadence IC design suite.Hellenic Foundation for Research and Innovation (HFRI) [19286]The research work was supported by the Hellenic Foundation for Research and Innovation (HFRI) under the 5th Call for HFRI PhD Fellowships (Fellowship Number: 19286).

What Factors Drive Cross-Country Economic Freedom Convergence?
No full textAre the economic freedom levels of all countries converging now that the Cold War is over? If not, are they converging into a subset of economic freedom groups or 'clubs' based upon underlying legal origins and country characteristics? This study investigates these questions using recent methodological developments in panel data convergence analysis. Our tests indicate non-convergence of economic freedom across all countries. However, club convergence tests reveal three distinct convergence clubs. Our subsequent results demonstrate that countries belonging to the higher economic freedom convergence clubs are less likely to have French legal origin and lower reliance on natural resource rents, and more likely to have long tenured and democratic governments, easier exitability, more net migration, faster economic growth, more control of corruption, as well as more elderly and dense populations.The authors appreciate the comments from session participants at the 2023 Southern Economic Association meetings in New Orleans, LA as well as feedback on an earlier draft from Nicolas Cachanosky and Louis Rouanet. We also thank the editors and referees for their comments which strengthened the manuscript.

kullanlarak gerçekleştirilmiştirFotonik kristaller, fotonların hareketlerini yönlendiren ve sınırlayan periyodik
optik yapılardır. Bu yönlendirme ve sınırlama için kullanılabilecek en etkili
araçlardan birisi de kavite yapılarıdır. Fotonik kavite yapıları, frekans, ışığın hızı
ve gecikmeler gibi bir，cok önemli parametrenin hassas kontrol edilmesini sağlar.
Bu yapılar, ışık-madde etkileşimlerinin yoğunlaştırılmasında ve fotonik cihazların
verimliliğinin artırılmasında kritik rol oynarlar. Fotonik kristal kavite yapıları,
ışığın tamponlanması, filtrelenmesi gibi pek ，cok uygulamanın yanı sıra optik
sensörler, optik mantık kapıları, dar ve geniş bant filtreler gibi bir，cok fotonik
cihazın temelini oluştururlar.
Bu ，calışmada, fotonik kavite yapıların eşlenik kavite dalga kılavuzu olarak
kullanımı ¨uzerine simülasyon ，çalışmaları gerçekleştirilmiştir. Yapılarda simetrinin
azaltılmasının frekans, grup hızı ve grup hız dağılımı (GVD) gibi parametreler
üzerindeki etkileri düzlem dalga açılımı (PWE) ve sonlu farklar zaman bölgesi
(FDTD) yöntemleri kullanılarak incelenmiştir. Özellikle, simetri kırılmasının
gökkuşağı tuzaklaması (Rainbow Trapping, RT) fenomenine nasıl katkıda
bulunduğu araştırılmıştır. Gökkkuşağı tuzaklaması, ışığın belirli dalga boylarının
farklı pozisyonlarda hapsedilerek yavaşlatıldığı bir fenomendir ve bu sayede optik
sinyallerin gecikme hatları ve veri depolaması gibi uygulamalarda kullanılabilir.
Çalışmamız, düşük simetri ve RT tekniklerinin bir arada kullanılarak fotonik
kristal kavite yapılarının performansının nasıl artırabileceği üzerinedir. Bu
çalışmamız sonucunda düşük simetri etkisiyle optik parametrelerin iyileştirilmesi
sağlandı ve başarılı bir ，şekilde RT gerçekleştirildi.Photonic crystals are periodic optical structures that guide and confine the
movement of photons. One of the most effective tools for this guidance and
confinement is the use of cavity structures. Photonic cavity structures enable the
precise control of many important parameters, such as frequency, light speed, and
delays. Moreover, these structures play a critical role in enhancing light-matter
interactions and improving the efficiency of photonic devices. Photonic crystal
cavity structures form the foundation of numerous photonic devices, including
optical sensors, optical logic gates, and both narrow and broad-band filters, in
addition to applications like buffering and filtering of light.
In this study, simulations were conducted to investigate the use of photonic
cavity structures as coupled cavity waveguides. The effects of symmetry reduction
on parameters such as frequency, group velocity, and group velocity dispersion
(GVD) were analyzed using the plane wave expansion (PWE) and finite-difference
time-domain (FDTD) methods. Specifically, we explored how symmetry breaking
contributes to the phenomenon of rainbow trapping (RT). Rainbow trapping is a
phenomenon where light of specific wavelengths is slowed and trapped at different
positions, enabling applications such as optical delay lines and data storage. This
study focuses on how the performance of photonic crystal cavity structures can
be enhanced by combining low-symmetry effects with RT techniques. As a result
of our work, both the improvement of optical parameters through low-symmetry
effects and the successful realization of these improvements were achieved RT
Unveiling the Gaps: Analyzing Family Physicians' Perspectives on Infectious Disease Notification in Türkiye
No full textUzun, Suleyman Utku/0000-0002-8876-2848; Mut, Hakan/0000-0003-0589-6072Objective: This study aimed to assess the opinions, attitudes, and behaviors of family physicians in T ; uuml;rkiye regarding mandatory communicable disease notification. Design: Cross-sectional study. Setting: A national online survey in T ; uuml;rkiye. Participants: This study was conducted among 397 family physicians from different geographical regions in T ; uuml;rkiye. Main Outcome Measure(s): Family physicians' opinions, attitudes, and behaviors regarding infectious disease notification. Results: The majority of family physicians (69.3%) felt inadequate in terms of knowledge about the notification system and 70.3% desired post-graduation training on communicable disease reporting. About one-third of the participants were dissatisfied with the current notification system. Reasons for under-reporting included lack of time, lack of feedback, and uncertainty about post-notification procedures. Factors significantly associated with higher infectious disease notification attitude scores (IDNAS) were receiving training on communicable disease reporting, feeling competent about reporting, and being satisfied with the reporting system (P .001). However, physicians who admitted choosing a different ICD code to avoid filling out an infectious disease notification form had lower IDNAS scores (P .001). Conclusion: This study highlights knowledge gaps and negative attitudes among family physicians in T ; uuml;rkiye regarding infectious disease reporting. Addressing these challenges requires continuous education and training programs. Feedback mechanisms should be improved to enhance physicians' engagement in the notification process. Reducing the workload of family physicians and simplifying the reporting process may also contribute to higher compliance with mandatory communicable disease reporting

No full textYildiz, Nagihan/0000-0003-1559-9522Purpose To investigate the awareness of the pelvic floor muscles (PFMs) and PFM exercises (PFME) knowledge, training and experience in community-dwelling women aged 60 and over and its relationship with urinary incontinence (UI). Methods This is a questionnaire based study which was carried out in 9 Physical Medicine and Rehabilitation Centers, including a total of 500 women aged 60 and over and living in the community. The questionnaire included questions about awareness of PFMs, UI complaints and PFME knowledge, training and experience. Knowledge and awareness of PFMs and PFME knowledge, training and experience were compared in subgroups with or without urinary incontinence. Results The mean age of the women included in the study was 67.8 +/- 6.1 (60-88). Knowledge and awareness of PFMs and PFME knowledge, training and experience were low in the study population. Knowledge and awareness of PFMs were significantly low in the subgroup with urinary incontinence (p 0.05). Kegel exercise training and experience were significantly low in the subgroup without urinary incontinence (p = 0.01, p 0.01). Conclusion Knowledge and awareness of PFMs and PFME knowledge, training and experience are low in community-dwelling women aged 60 and over and training programs should be organized to teach the function of the PFMs and to perform PFME correctly in this population

No full textBu çalıĢmada; Ali ġîr Nevâyî’nin Türkçe divanlarından Garâ’ibü’s-Sıgar, Nevâdirü’Ģ-ġebâb, Bedâyi’ül-Vasat ve Fevâidü’l-Kiber’deki olumsuzluk, yokluk ve soru Ģekilleri üzerine odaklanılmıĢtır. Ali ġîr Nevâyî’nin Türkçe divanları üzerine yapılan yazı çevirimli yayınlar esas alınarak oluĢturulan bu çalıĢmanın hareket noktası, Ali ġîr Nevâyî’nin Türkçe divanlarında bir iĢaretleyiciyle olumsuzlaĢtırılmıĢ yokluk ve soru ifadesine büründürülmüĢ sözcükler, söz öbekleri ya da cümlelerdir. Bu eser üzerinde inceleme yapılırken iĢaretleyicilere sahip olan yapıların yanında, herhangi bir iĢaretleyiciye sahip olmayan ancak olumsuz bir anlam ifade eden yapılar tespit edilmeye çalıĢılmıĢtır. Bunun yanı sıra yokluk ve soru Ģekillerinin olumsuzluk kavramındaki yeri değerlendirilmiĢtir. Ayrıca soru yapılarının olumsuzluk ve yokluk Ģekilleri ile birlikte ele alınıp değerlendirilmesi gerekmektedir. Nitekim soru Ģekilleri baĢlı baĢına bu tezde ele alınmayıp olumsuzluk kavramı içerisinde değerlendirilmiĢtir. Öte yandan bağlam merkezli ilerleyip seçilen örneklerin ortak biçimi olan ek hakkında baĢlığın içerisinde köken ile ilgili bilgi verilmeye çalıĢılmıĢtır. Bunun sonucunda metne odaklanılıp yapıların Ģahıslardaki ifade Ģekli ve anlamlarında görülen etki üzerinde durulmuĢtur. Standart olumsuzluk iĢaretleyicileri -mA eki, yok ve irmes kelimelerinin olumsuzluğu yansıtma durumları, olumsuzluğun biçim birimle iĢaretlenmediğinde nasıl sağlandığı, hangi yollarla alıcıda olumsuzluk duygusunun yaratıldığı, yokluk kategorisi ve soru kategorisi seçilen divanlardan hareketle bağlam göz önünde tutularak incelenmiĢtir. Türk dili tarihinde, olumsuzluk, yokluk ve soru Ģekilleri hakkında kuramsal çalıĢmalar bulunmaktadır. Bu bağlamda çalıĢmanın Nevâyî araĢtırmalarına katkı sağlayacağı ve Nevâyî’nin eserlerinde olumsuzluk, yokluk ve soru kategorisinin nasıl değerlendirildiğini içeren temel bir çerçeve çizileceği öngörülmektedir.This study focuses on the use of negation, absence, and question constructions in the Turkish divans of Ali ġîr Nevâyî: Garâ’ibü’s-Sıgar, Nevâdirü’Ģ-ġebâb, Bedâyi’ül-Vasat and Fevâidü’l-Kiber. The starting point of this analysis is based on published translations of Ali ġîr Nevâyî’s Turkish divans, which include significant amounts of material. This material includes words, phrases, and sentences where negation, absence, or question markers are employed. The study examines structures that contain these explicit markers, as well as those that express negation without any formal markers. Additionally, the study explores the place of absence and question forms within the broader concept of negation. It is also necessary to address and evaluate question structures alongside negation and absence forms. In fact, question forms are not analyzed independently in this study, but are considered within the concept of negation. On the other hand, the study progresses contextually, and information about the origin of the common suffix in the selected examples is provided in the title. As a result, the focus is placed on how these structures are articulated and the effect of their expression and meaning in relation to different participants. The standard markers of negation, such as the -mA suffix, and the words yok and irmes, are analyzed in terms of how they reflect negation. The study also examines how negation is conveyed when no formal marker is present, the ways in which negation is perceived by the reader, and the categories of absence and question, all within the context of the selected divans. In the history of Turkish linguistics, there are theoretical studies on negation, absence, and question forms. In this context, it is anticipated that the present study will contribute to Nevâyî research by providing a foundational framework for understanding how negation, absence, and question categories are addressed in his works
