Synthesis, Characterization, and Biological Investigation of Antimony(III) Halide Complexes With Different Coordination Architectures Constructed From Thiophene Thiosemicarbazones
No full textIn this study, we report the synthesis, characterization, and biological investigation of antimony(III) halide complexes with various coordination architectures constructed from thiophene thiosemicarbazones. Antimony(III) thiophene-2-carbaldehyde thiosemicarbazone complexes (1, 2, 4, and 5) exhibit a square pyramidal geometry, with ligands coordinated to the central antimony atom in two distinct binding modes. In contrast, antimony(III) 2-acetylthiophene thiosemicarbazone complexes (3, 6, and 7) adopt a seesaw geometry. These complexes (1-7) represent the first reported examples of antimony(III) halide thiosemicarbazone compounds. The unique coordination environments observed in these complexes are of significant importance within the realm of antimony chemistry. These synthesized complexes exhibit different coordination geometries as well as potential biological activities. The antiproliferative activity against the human breast adenocarcinoma (MCF-7) cell line and antimicrobial activity against Gram-positive and Gram-negative bacteria were assessed. Antimony(III) thiophene-2-carbaldehyde thiosemicarbazone complexes (1, 2, 4, and 5) showed significant antiproliferative activity with IC50 values ranging from 8.5 to 19.1 mu M, while antimony(III) 2-acetylthiophene thiosemicarbazone complexes (3, 6, and 7) had higher IC50 values. Additionally, the antimony complexes demonstrated selective antimicrobial activity against Gram-negative bacteria.Tekirdagbreve; Namimath;k Kemal UEniversitesi, Office of Scientific Research Projects [NKUBAP.01.DR.21.293]This research was carried out in partial fulfillment of the requirements for the Ph.D. thesis of O.U. under the supervision ofyI.I.O.

Nexus between environmental innovation and ecological footprint in OECD countries: is there an environmental rebound effect?
No full textThis study empirically examines the effect of environmental innovation on ecological footprint using a panel smooth transition regression (PSTR) model for 33 OECD countries, over the period 1995–2019. The findings indicate that a rebound effect occurs when the level of environmental innovation surpasses the calculated threshold level (14.254%), suggesting that environmental innovations exert pressure on the environment. Existing empirical results point to a rebound effect, which refers to offsetting the gains from environmental innovation by channeling them into production and consumption. © AESS 2024
Balancing green power: Hydropower and biomass energy's impact on environment in OECD countries
No full textThe climate crisis, driven by greenhouse gas (GHG) emissions and environmental degradation, demands a transition to renewable energy for sustainable development. This paper analyzes the asymmetric effects of hydroelectric and biomass energy consumption on the ecological footprint (EFP) for 24 OECD countries from 1970 to 2022. By using a combination of advanced econometric approaches, including Method of Moments Quantile Regression (MMQR), Generalized Linear Models (GLM), and Robust Least Squares (RLS), with machine learning techniques such as Multivariate Adaptive Regression Splines (MARS) and Neural Networks (NN), this study will be able to identify complex nonlinearities that are not captured by traditional models. The results reveal that hydroelectric energy significantly reduces the EFP, particularly in high-pollution contexts, while biomass energy consumption worsens environmental degradation. These findings emphasize the urgent need for targeted policies to maximize the benefits of renewable energy sources and mitigate their risks. The study contributes to the literature by offering a comprehensive framework to analyze the environmental impacts of renewable energy, emphasizing the importance of methodological diversity and advanced modeling techniques as ways to achieve sustainability goals

Investigation of the effect of ultraprocessed food consumption on asthma using pulmonary function tests
No full textBackground: NOVA is a food classification system that classifies foods according to the scope and purpose of food processing, rather than nutrients. Asthma is usually characterized by chronic inflammation and respiratory symptoms such as wheezing, shortness of breath, chest tightness, cough, and variable expiratory airflow limitation. According to the NOVA food classification system, consumption of ultraprocessed foods (UPF) can affect asthma symptoms. Aim: In this study, the relationship between UPF consumption and pulmonary function test (PFT) results of asthma patients in adults aged 18 to 65 was investigated using biochemical parameters. Methods: This study was a cross-sectional study and, was conducted with 339 asthmatic participants diagnosed with asthma and receiving medical treatment. The participants' consumption of UPF was determined using a food frequency questionnaire. The evaluation of forced expiratory volume in one second (FEV1) (L/s) and forced vital capacity (FVC) (L/s) in the respiratory function tests was based on the percentage of the measured and expected values. Results: Although no significant relationship was found between % FEV1 expected value and UPF consumption (P > 0.05), it was concluded that % FVC expected and % FEV1/FVC values decreased with increasing UPF consumption (P < 0.05). Conclusion: It has been concluded that consumption of UPF worsens respiratory function and asthma prognosis. Therefore, replacing UPF and beverage products with healthier foods or food processing methods will play an important role in maintaining health.Chest Surgery Education and Research Hospital, Istanbul, TurkeyWe acknowledge the Istanbul Yedikule Chest Diseases and Chest Surgery Education and Research Hospital, Istanbul, Turkey
Copernicus Yüksek Çözünürlüklü Katman Geçirimsizlik Yoğunluğu (HRL IMD) Verileri Kullanılarak Geçirimsizlik Derecelerinin Haritalanması ve Gelecek Tahmini: Amasya Kenti Örneği
Get PDFIt is very important to comprehensively address built-up areas in cities and the resulting urban conditions for sustainable urban planning. In this study, using Copernicus High Resolution Layer Imperviousness Density (HRL IMD) data (2006, 2009, 2012, 2015, and 2018), urban imperviousness degrees were classified and mapped at the scale of Amasya city and urban land change rates were calculated over the years. In the study, mathematical calculations were made using linear and polynomial regression models to determine what the future (2030) imperviousness degrees would be if the determined changes continue in the same way. According to the results of the study, it has been determined that urbanization has shown an increasing trend in all districts of Amasya province during the relevant years and this situation has been parallel to the increase in impervious surface areas, and it is predicted that these impervious surfaces will continue to increase significantly in the future. In this context, with this study, in which the city of Amasya is evaluated as a pilot region, it is concluded that regular observation of impervious surface area changes in the coming years and the development and implementation of a controlled urbanization policy will help to protect natural areas and prevent biological damage.Sürdürülebilir kentsel planlama için kentlerdeki yapılaşmış alanların ve ortaya çıkardığı kentsel koşulların kapsamlı bir şekilde ele alınması oldukça önemlidir. Bu çalışmada, Copernicus Yüksek Çözünürlüklü Katman Geçirimsizlik Yoğunluğu (HRL IMD) verileri kullanılarak (2006, 2009, 2012, 2015 ve 2018 yılları) Amasya kenti ölçeğinde kentsel geçirimsizlik dereceleri sınıflandırılarak haritalanmış ve yıllara göre kentsel arazi değişim oranları hesaplanmıştır. Çalışmada, belirlenen değişimlerin aynı şekilde devam etmesi durumunda gelecekteki (2030 yılı) geçirimsizlik derecelerinin ne olabileceğini belirlemek amacıyla doğrusal ve polinom regresyon modelleri kullanılarak matematiksel hesaplamalar yapılmıştır. Çalışma sonucuna göre, Amasya iline bağlı tüm ilçelerde ilgili yıllar boyunca kentleşmenin artış eğilimi gösterdiği ve bu durumun geçirimsiz yüzey alanlarındaki artışla paralellik gösterdiği tespit edilmiş olup, gelecekte de söz konusu geçirimsiz yüzeylerin önemli ölçüde artmaya devam edeceği öngörülmektedir. Bu bağlamda, Amasya kentinin bir pilot bölge olarak değerlendirildiği bu çalışma ile önümüzdeki yıllarda geçirimsiz yüzey alan değişimlerinin düzenli olarak gözlemlenmesi ve kontrollü bir kentleşme politikasının geliştirilerek uygulanmasının, doğal alanların korunması ve biyolojik tahribatın önlenmesinde etkili olabileceği düşünülmektedir
Filistin Halkının Zor Sınavı: Geçmişten Bugüne Gıdaya Erişim Zorlukları
Get PDFThis study underscores the importance of the right to food as part of the broader human rights and human security framework during times of war and conflict. The results show that war-induced destruction of food supply chains endangers the physical and social stability of people. Focusing on the conflict in Palestine, the study finds that the blockade, destruction of infrastructure, and restrictions on humanitarian aid have pushed 86% of the population into acute food insecurity. This has resulted in chronic health problems, including increased malnutrition rates and developmental disabilities among children. Israel’s strategies systematically violate the right to access food and constitute a flagrant breach of international law. These actions infringe on the Palestinian people’s right to food and their human dignity. The research highlights Israel’s agenda to displace Palestinians from their lands, framing this within the context of the ongoing Israeli-Palestinian conflict. While existing literature addresses the challenges of food access in times of war, this study identifies significant gaps, especially in the inadequacy of humanitarian intervention strategies and the lack of international cooperation. The findings emphasize the urgent need for sustainable humanitarian assistance models and stronger international oversight to enhance food security during wartime. This study contributes to the literature by addressing these gaps and proposing strategies to strengthen global food security in times of war.Bu çalışma, savaş ve çatışma dönemlerinde gıdaya erişim hakkının insan hakları ve insani güvenlik bağlamındaki kritik önemini ele almaktadır. Bulgular savaşın gıda tedarik zincirlerine verdiği zararların bireylerin fiziksel ve sosyal istikrarını tehdit ettiğini ortaya koymaktadır. Filistin'deki çatışmalara odaklanan araştırma abluka, altyapı yıkımı ve insani yardım kısıtlamalarının nüfusun %86'sını akut gıda güvensizliği içinde bıraktığını göstermektedir. Bu durum, çocuklarda yetersiz beslenme ve gelişim bozukluğu oranlarının artması gibi uzun vadeli sağlık sorunlarına yol açmaktadır. Araştırma gıdaya erişimin İsrail'in stratejileri içinde sistematik bir şekilde ihlal edildiğini göstermektedir. Uluslararası hukukun açık bir ihlali olan bu stratejilerin sonucunda Filistin halkının gıdaya erişim hakkının gıdaya erişim hakkının kısıtlandığı, aynı zamanda insan onurunun ayaklar altına alındığı görülmektedir. Çalışma, Filistin-İsrail savaşı gibi görünen ama aslında İsrail'İn Filistin halkını topraklarından etme stratejisini gıda erişimi özelinde ele almaktadır. Mevcut literatürde savaş sırasında gıda erişimi konusundaki eksiklik doldurulmaya çalışılmıştır. Araştırma ayrıca insani müdahale stratejilerinin yetersizliğini ve uluslararası iş birliğinin eksikliğini ortaya koymaktadır. Bulgular savaş dönemlerinde gıda güvenliğini sağlamaya yönelik sürdürülebilir insani yardım modellerine ve daha güçlü uluslararası denetim mekanizmalarına duyulan ihtiyacı vurgulaması açısından önemlidir ve bu yönüyle literatüre önemli bir katkı sunmaktadır
Tensile performance of inclined adhesive anchors in steel fiber-reinforced concrete
Get PDFIn almost all studies on post-installed anchors in concrete, the anchor direction is perpendicular to the concrete surface. However, the anchor direction may not be perpendicular to the concrete surface due to application errors or requirements. In the study, the effect of inclination angle is examined experimentally for non-perpendicular anchorage to steel fiber-reinforced concrete. Anchor inclination angle (0 degrees, 15 degrees, and 30 degrees), fiber volume fraction (0%, 1.5%, and 3%), and embedment depth (40, 60, and 80 mm) are considered variables. Trial points are decided using the Box-Behnken experimental design approach. An 8 mm diameter deformed steel bar and two-component epoxy acrylate-based chemical adhesive are used for anchorage. Load-displacement curves, ultimate loads, and failure modes are determined through tensile tests. It is concluded that as the fiber fraction increases, failure modes modify and the negative effect of the inclination angle decreases, particularly in cases of small embedment depth.Tekirdag Namimath;k Kemal University Scientific Research Projects Coordination Unit [NKUBAP.06.YL.23.456]The Tekirdag Nam & imath;k Kemal University Scientific Research Projects Coordination Unit supported this work [Project No: NKUBAP.06.YL.23.456]
National Identity and Syrian Migration: A Journey for Self-Discovery
Get PDFBu makale, Suriye'nin tarihsel ve toplumsal yapısının Suriyeliler arasında güçlü bir ulusal kimliğin gelişmesine etkisini ve bu kimlik eksikliğinin mülteci olarak deneyimlerini nasıl etkilediğini incelemektedir. Bu makale, Suriyeli kimliğinin tarihsel dinamiklerini analiz etmekte ve Suriye kültürünin ve tarihinin Suriyelilere istikrarlı ve tutarlı bir benlik duygusu sağlamadığını ortaya koymaktadır. Farklı etnik ve mesleki geçmişlerden gelen tanıkların hikayelerini kullanarak Suriyeli mültecilerin kimlik krizine ışık tutmaktadır. Ulusal bir toplum olmanın Suriyeliler için uzun süredir devam eden bir çaba olduğunu ve Suriyeli mültecilerin yerlerinden edilip başka ülkelere yerleştirilmesinin postmodern kimlik kavramlarına meydan okuduğunu savunmaktadır. Kimlik akışkandır ve kültürel karşılaşmalar yoluyla sürekli olarak üretilirken, bir ulusun benzerliklerini vurgulayan yadsınamaz öz bir katman vardır. Fakat, makalede paylaşılan hikayeler gösteriyorki, Suriyeli mülteciler güvenli bir coğrafyada daha parlak bir gelecek inşa etmek için yeni bir kimlik arayışı içerisindeler. Yeni kültüre adapte olmaya çalışırken, etnik kökenlerini göz ardı ederek ve entegrasyon yerine asimilasyon sürecini tercih ederek oldukça incelemeye değer bir olgu sunmaktadırlar. Bu bağlamada, bu çalışma Suriyeli mültecilerin Türkiye ve diğer ülkelerde ki durumuna ışık tutarak, ulusal entegrasyonun sağlanmasında ve kültürleşme sürecinde mültecilerin ulusal kimlikleriyle bağlarının korunmasında temel kimliğin önemini vurgulamaktadır.This article examines how Syria's historical and social structure prevents the development of a strong national identity among Syrians and how this lack of identity affects their experiences as refugees. This article analyses the historical dynamics of Syrian identity and reveals that Syrian culture and history have not provided Syrians with a stable, coherent sense of self. Discussing the identity crisis of Syrian refugees and using testimonials from diverse ethnic and professional backgrounds, this article argues that the establishment of a national community has been a longstanding endeavour for Syrians and that the displacement and relocation of Syrian refugees in other nations challenge the postmodern notions of identity. While contemporary approaches see identity as fluid and constantly being produced through cultural encounters, there is an undeniable essentialist layer that emphasises the similarities of a nation. The case of Syrian refugees highlights the importance of this essential layer that constitutes the sense of belongingness to a nation. Searching for a new identity to construct a brighter future within a safe landscape, Syrian refugees try to leave their national identity behind and appreciate the new culture. Moreover, they discount their ethnic roots and prefer the process of assimilation rather than integration. Therefore, this study examines the stories of Syrian refugees highlighting the importance of essential identity in bringing about national integration and preserving a connection during acculturation
