1-(2-Hydroxyethyl)-2-imidazolidinone as corrosion inhibitor of mild steel in 0.5 M HCl solution: thermodynamic, electrochemical and theoretical studies
(Journal of Adhesion Science and Technology, 2019) Keleşoğlu, Ayşen; Yıldız, Reşit; Dehri, İlyas; Yıldız, Reşit
The inhibition effect of 1-(2-Hydroxyethyl)-2-imidazolidinone (2-HEI) on mild steel (MS) corrosion in 0.5M HCl solution was investigated at different inhibitor concentration and temperature by electrochemical experiments, such as linear polarization resistance (LPR), electrochemical impedance spectroscopy (EIS), potentiodynamic polarization and quantum chemical calculations. The inhibitor adsorption process on mild steel in 0.5M HCl system was studied at different temperatures (20 C–50 C). Furthermore, the surface morphology of MS was also investigated with SEM in the absence and the presence of inhibitor. The adsorption of 1-(2-Hydroxyethyl)-2-imidazolidinone on MS surface is an exothermic process and this process obeys the Langmuir adsorption isotherm. The Quantum chemical findings are good agreed with the empirical data.
16. Asır Kudüs’ünde Bir İlim Kurumu Taziyye: Medresesi
(Hitit Üniversitesi, 2022) Evsen Aydın, Esra
Üç semavi din için kutsal kabul edilen, bu nedenle tarih boyunca bu üç dine mensup devletlerin şehre hâkim olma mücadeleleri verdiği, yeryüzünde bu özellikte tek şehir olan Kudüs Müslümanlar için de tarihleri boyunca önemli bir konumda olmuştur. İslam idaresinde olduğu her dönemde Mekke ve Medine’den sonra üçüncü harem kabul edilen, tamamı Mescid-i Aksa olarak anılan Harem-i Şerif alanı başta olmak üzere şehrin her köşesinde Müslüman bir kimlik oluşturmak amacıyla imar ve inşa faaliyetleri devam etmiştir. Coğrafi konumu sebebiyle ticaret merkezi özelliği taşımayan, Haçlı seferlerinin olduğu dönem dışında askeri ve siyasi olarak da merkezi bir konumu olmayan Kudüs, Müslümanların hâkim olduğu zamanlarda mukaddes bir dini merkez olmanın yanında önemli bir ilim merkezi özelliği de taşımıştır. Şehirde inşa edilen medreseler, tekke ve zaviyeler, ribâtlar, hankahlar gibi müstakil dini ve ilmi kurumların yanı sıra Mescid-i Aksa’nın kendisi de sadece ibadet için kullanılan bir mescit olmayıp her zaman cami dersleri, zikir meclisleri, mestabe denilen ve avlusunda kurulan ilim halkalarıyla canlı bir ilim merkezi fonksiyonu icra etmiştir. Şehirde ilim kurumlarının tesisi Eyyûbîler döneminde başlayarak Memlükler ile zirveye ulaşmış, Osmanlılar döneminde ise daha çok mevcut sistemin, kurumların ve bu kurumları ayakta tutan vakıfların muhafazasını sağlayan bir siyaset takip edilmiştir. Osmanlı idaresine geçtikten sonra Kudüs’te bulunan medreselerin işleyişini nasıl devam ettirdiği, vakıf müessesesinin kontrolü gibi konuların anlaşılması için Kudüs medreseleri üzerine yapılacak müstakil çalışmaların sayısının artması önemlidir. Bu alanda literatüre katkı sağlamayı amaçlayan bu makalenin konusu; önemli askeri ve idari hizmetlerde bulunan, ancak ömrünün son demlerinde yaşadığı siyasi sorunların ardından bir tür emeklilik ihsanı olarak Kudüs’te yaşama talebi kabul edilen Memlük emiri Emir Tâz tarafından inşa ettirilen, orta büyüklükte olduğunu düşündüğümüz Tâziyye Medresesi’dir. Mescid-i Aksa çevresinde kurulan ve sayıları elliyi aşan medreseden biri olan Tâziyye, XVI. asırda nüfusu ancak 5 bin civarında olan şehirdeki canlı ilim hayatının bir şahidi olarak Osmanlı devletinin hâkimiyeti döneminde de faaliyetine devam etmiştir. Osmanlı döneminde Arap coğrafyasında bulunan medreselerin yapısını ve işleyişini ele alan literatürde mevcut çalışmalar daha çok vakfiyesi bugüne gelen veya mansıp sahiplerinin ve talebelerinin izinin tabakât kitaplarından sürülebildiği yani hakkında malumata ulaşmanın nispeten kolay olduğu daha büyük ölçekli ve görünürlüğü olan yapılara odaklanmaktadır. Bu makalenin amacı ise, XVI. asırda Kudüs’ün ilmi kurumlarını ve yapısını anlayabilmek için büyük ve görünür bir örneğin değil, şehirde sayıca daha fazla olan ancak hakkında sınırlı miktarda malumata rastlanan orta ölçekli bir örneğin izini sürerek literatüre kazandırmaktır. Bunun için XVI. asırda farklı tarihlere ait Şer̒iyye sicilleri ve mühimme kayıtları ile literatürde mevcut çalışmalara müracaat edilecektir. Kudüs Şer̒iyye sicilleri Arapça olup defterlerin fiziki şartları ve yazı karakterleri sebebiyle okunması konusunda zorluklarla karşılaşıldığı için Türkçe literatürde, merkezine doğrudan bu yerel kaynakları alarak konuyu inceleyen çalışma sayısının az olması nedeniyle bu makale bu yönüyle de alana katkı sağlamayı amaçlamaktadır. Makale beş başlıktan oluşmaktadır. İlk başlıkta medresenin vâkıfı olan Memlük emiri Emir Tâz hakkında biyografik bilgilere, ikinci başlıkta medresenin mekânsal özelliklerine yer verilmiştir. Medresenin devamlılığı için en önemli unsur olan vakıf gelirlerinin ve bu işleyişte görevli kişilerin ele alındığı üçüncü başlıkta hem medresenin maddi desteğinin büyüklüğü incelenmiş hem işleyişte karşılaşılan bazı sorunlar ortaya konmuştur. Dördüncü başlıkta medresenin tedris faaliyetinin unsurlarına odaklanarak Kudüs medreselerinde mansıpların tevcihi, mansıp elde etmek için rekabet, medresenin tedris kapasitesi ve sunduğu imkânlar gibi konulara Tâziyye Medresesi özelinde yer verilmiştir. Beşinci başlıkta ise medresedeki diğer dini hizmetler incelenmiştir. Vakfiyesi bugüne ulaşmayan medresenin vakıf şartlarının detaylarına ve tarih boyunca değişime uğrayıp uğramadığı bilgisine ulaşmak henüz mümkün olmadığı gibi mevcut malumat tedrisin mahiyetine ve okutulan eserlerin hangileri olduğuna dair de detaylı bilgi elde etme imkânı sunmamaktadır. Kudüs ile alakalı medreseler ve daha büyük çerçevede ilmi hayat ile alakalı çalışmaların sayısı arttıkça literatürde bulunan bu boşlukların da doldurulması mümkün olacaktır.

Phonocardiogram is used for ambulatory diagnostic to assess health status of heart and detect cardiovascular disease. The goal of this study is to develop automatic classification method of PCG recordings collected from different databases and recorded in a different way. For this purpose, after various time and frequency domain features are extracted from PCG recordings obtained from two databases, recordings are subjected to pre-classification in order determine which database they are obtained from. Before final classification, various time, frequency and time-frequency domain features of classified recordings are extracted. These features are fed into four different classification ensembles trained with training dataset. With final decision rule, proposed algorithm achieved an accuracy of 98.9%, a sensitivity of 93.75% and a specify of 99.5%.
Abu Ubayd’s Understanding Of Naskh;
(Hitit University, 2022) Yaşar, M.A.; Nas, T.
In the period when Islamic sciences were formed, a large number of scholars with absolute ijtihad capacity were trained. One of the scholars mentioned is Abu ‘Ubayd al-Qāsim ibn Sallām al-Khurāsānī al-Harawī who was educated by many famous scholars of the period, had a great influence on both the scientific and political circles. For this reason, he could not be shared by different sect biographers. As a matter of fact, some Shafi’i tabaqat writers counted Ebû Ubeyd as a follower of Imam Shafii. On the other hand, some Hanbali scholars have mentioned Ebû Ubeyd among the class of Hanbali scholars. However, it was concluded that it would be more correct to see Ebû Ubeyd as an independent mujtahid rather than a follower of any madhhab. For, in his own works, the fact that he refers more to Imam Malik rather than Imam Shafii and Ahmad ibn Hanbal and sometimes refers to the views of Abu Hanifa and Imamey indicates this. Ebû Ubeyd, who came to the forefront with his faqih and muhaddis aspects, had a deep knowledge of the subject of naskh, which has a close relationship with these two sciences, and in this regard, he wrote a rare work called en-Nâsiḫ ve’l-mensûḫ fi’l-Ḳurʾâni’lʿazîz ve mâ fîhi mine’l-ferâʾiż ve’s-sünen. While revealing Ebû Ubeyd’s understanding of naskh, his work en-Nâsiḫ ve’l-mensûḫ was used as the main source. In addition to this, his other works related to the subject, especially his work called Kitâbu’l-emvâl, were among the first hand sources that were consulted. It has been tried to determine his approach to naskh based on the statements he made on the subject and the examples he gave in this regard. In this context, Ebû Ubeyd’s approach to the nature and framework of naskh and his views on the evidences that can abrogate each other are examined in this study. Ebû Ubeyd discussed the abrogation in a broader sense as “the modification of a shar’i ruling by a later evidence”, not the established meaning in the methodology as “removal of a shar’i ruling with a later shar’i proof”. In this context, naskh is also used for the allocation of public, the denial of the absolute, the statement of conciseness, the correction of a wrong understanding and the exception made from a general rule. This is known as the understanding of naskh among the companions, tābi‘īn and early convert scholars. However, although Ebû Ubeyd is at the same age as Imam Shafii and has copied and benefited from his works, it is noteworthy that he preferred the predecessor’s approach to the subject rather than the naskh understanding he adopted. It is important to investigate this. He adopted the approach of the public regarding the Shari’a evidences of Ebû Ubeyd that could naskh each other. According to him, the verses of the Qur’an can naskh each other. He gave many examples of this. Another point that draws attention here is to ascribe the concept of naskh used for the verse of the Qur’an by Ebû Ubeyd, from the Lawh-i Mahfuz, in the form of a verse whose recitation is lasting and its meaning is naskhed, and a verse that is removed from people’s hearts by canceling both its recitation and used in different meanings. Ebû Ubeyd stated that sunnah can be naskhed with sunnah, without making any distinction between ahad and mutawatir about sunnah and its naskh. However, despite giving many examples of the naskh of the âhâd sunnah with its own like, no example has been encountered of the naskh of the âhâd sunnah with its own like or with âhâd and the âhâd sunnah with the mutawatir sunnah. As it can be understood from my statements on the subject, Ebû Ubeyd saw that it is permissible to naskh both mutawatir and ahad sunnah with the Qur’an. However, while there is an example for the naskh of the ahad sunnah with the Qur’an in his related works, there is no example for the other. Although there is no clear statement on the issue that the Qur’an can be naskhed with the sunnah, it is understood from some examples that he gives permission for this. © Published by Hitit Ü niversitesi İlahiyat Fakültesi – Hitit University Divinity Faculty, Çorum, Turkey.

Activated Carbon-Coated Iron Oxide Magnetic Nanocomposite (ionps@ctac) Loaded With Morin Hydrate for Drug-Delivery Applications
(Frontiers Media Sa, 2024) Dogan, Yusuf; Ozic, Cem; Ertas, Erdal; Baran, Ayse; Rosic, Gvozden; Selakovic, Dragica; Eftekhari, Aziz; Doğan, Yusuf
Cancer is a major disease that affects millions of people around the world every year. It affects individuals of all ages, races, and backgrounds. Since drugs used to treat cancer cannot distinguish between cancerous and healthy cells, they cause systemic toxicity along with serious side effects. Recently, controlled drug-release systems have been developed to reduce the side effects caused by anticancer drugs used for treatment. Morin is an anticancer drug with a flavonol structure. It has been extensively researched for its antioxidant, anti-inflammatory, antitumoral, and antibacterial properties, especially found in Chinese herbs and fruits, and its multiple positive effects on different diseases. In this study, a nanocomposite with magnetic properties was synthesized by coating biocompatible activated carbon obtained using the fruits of the Celtis tournefortii plant on the surface of iron oxide magnetic nanoparticles. Characterization of the synthesized activated carbon-coated iron oxide magnetic nanocomposite was confirmed by Fourier transform infrared, scanning electron microscopy, energy-dispersive X-ray spectrometry, X-ray diffraction, dynamic light scattering, zeta potential, and vibrating sample magnetometry. The cytotoxic effects of the drug-loaded magnetic nanocomposite were examined in HT-29 (colorectal), T98-G (glioblastoma) cancer cell lines, and human umbilical vein endothelial cell (HUVEC) healthy cell line. The morin loading and release behavior of the activated carbon-coated iron oxide magnetic nanocomposite were studied, and the results showed that up to 60% of the adsorbed morin was released within 4 h. In summary, activated carbon-coated iron oxide magnetic nanocomposite carriers have shown promising results for the delivery of the morin drug.
Activity of Metalaxyl-M plus mancozeb, Fosetyl-Al, and Phosphorous Acid against Phytophthora Crown and Root Rot of Apricot and Cherry Caused by Phytophthora palmivora
(CZECH ACADEMY AGRICULTURAL SCIENCES, 2017) Türkölmez, Şahimerdan; Derviş, Sibel
Crown and root rot, caused by the Oomycete pathogen Phytophthora palmivora, has become a destructive disease of apricot and cherry in eastern Turkey. There are no currently registered fungicides labeled for its control. In greenhouse experiments conducted in 2012 and 2013, 1-year-old potted apricot rootstock Zerdali and cherry rootstock Mahaleb plants were treated either with foliar spray of fosetyl-Al (140, 160, and 180 g a.i./100 l) or phosphorous acid (187.5, 200, and 215 g a.i./100 l) or soil drench of 100 ml of metalaxyl-M (= mefenoxam)+mancozeb (12+192, 16+256, and 20+320 g a.i./100 l) one day after wound inoculation of crowns and roots. In both years, phosphorous acid at 200 and 215 g a.i./100 l, fosetyl-Al at 160 and 180 g a.i./100 l, and metalaxyl-M+mancozeb at 20+320 g a.i./100 l significantly reduced the root rot severity on Zerdali by 70.68-80.00% and crown rot severity on both Zerdali and Mahaleb, by 68.32-91.96 and 74.21-82.60%, respectively, compared with phosphorous acid at 187.5 g a.i./100 l, fosetyl-Al at 140 g a.i./100 l, metalaxyl-M+mancozeb at 12+192 and 16+256 g a.i./100 l and control. Moreover, fosetyl-Al at 180 g a.i./100 l and metalaxyl-M+mancozeb at 20+320 g a.i./100 l significantly reduced the root rot severity on Mahaleb compared to fosetyl-Al at 140 and 160 g a.i./100 l, metalaxyl-M+mancozeb at 12+192 and 16+256 g a.i./100 l, phosphorous acid treatments and control in 2012, providing the best control of the disease by 88.00-90.68%. Two/three phosphorous acid foliar applications at 200 g a.i./100 l suppressed symptom development when field applications were made on a curative basis in 2014 and 2015.
Adaptation of the Employee Spirituality Scale Into Turkish: a Study on Healthcare Workers
(Halil Eksi, 2025) Apak, H.
This study aimed to adapt the Employee Spirituality Scale to Turkish culture for healthcare professionals. A total of 230 healthcare workers participated in the adaptation of the scale, which comprises 24 items. The research data were collected face-to-face with a questionnaire that included demographic characteristics, the Employee Spirituality Scale, and the Spiritual Orientation Scale. Construct validity was analyzed using exploratory and confirmatory factor analyses. The two-factor structure of the Employee Spirituality Scale was confirmed in the Turkish sample and showed acceptable fit values. Because of CFA, 2 items were removed from the scale because they did not fit. For criterion validity, the Pearson Correlation Coefficient between the scale and the Spiritual Orientation Scale was calculated, and a significant positive result was obtained. This study demonstrated that the Turkish version of the Employee Spirituality Scale is a valid and reliable measurement tool for health care workers to assess the various dimensions of human spirituality that give individuals a sense of guidance, facilitate finding meaning and purpose in one’s tasks, enable them to overcome their weaknesses and limitations in the workplace, and assess various dimensions of human spirituality as a relationship with a higher power. © 2025 by Author(s).
Adaptions in subsistence strategy to environment changes across the Younger Dryas-Early Holocene boundary at Kortiktepe, Southeastern Turkey
(Sage Journals, 2022) Emra, Stephanie; Benz, Marion; Sıddıq, Abu Bakar; Özkaya, Vecihi
The site of Körtiktepe in southeastern Turkey is one of few sites in the Upper Mesopotamia basin that attests continuous, permanent occupation across the boundary from end of the colder, drier Younger Dryas (YD) into the comparatively wetter and warmer Early Holocene (EH). This allows for the study of the degree of environmental change experienced on a local level over this boundary as well as for the study of the adaptations that the occupants of the site undertook in response to these changes. The mammal assemblage of Körtiktepe remains relatively stable across the YD – EH transition with the main contributors to diet being mouflon (Ovis orientalis) and red deer (Cervus elaphus) in approximately the same quantities, although the contribution of aurochs (Bos primigenius) increases in the EH. The most significant changes can be seen in the shift in avifauna remains, with a sharp increase of waterbirds during the EH. It is proposed that these shifts reflect changes in the local environment with an increase in woodland cover as well as expansion of local waterways, which is generally consistent with previously published archaeobotanical studies. In terms of species exploited, mortality profiles as well as size distribution of mammals, a great deal of continuity is observed. This suggests that over this particular period the local impact of the beginning of the Early Holocene was not overly dramatic, allowing for cultural continuity of previously established subsistence strategies.
Adolescent Transport and Unintentional Injuries: a Systematic Analysis Using the Global Burden of Disease Study 2019
(Elsevier Sci Ltd, 2022) Peden, Amy E.; Cullen, Patricia; Francis, Kate Louise; Moeller, Holger; Peden, Margaret M.; Ye, Pengpeng; Ivers, Rebecca Q.
Background Globally, transport and unintentional injuries persist as leading preventable causes of mortality and morbidity for adolescents. We sought to report comprehensive trends in injury-related mortality and morbidity for adolescents aged 10-24 years during the past three decades. Methods Using the Global Burden of Disease, Injuries, and Risk Factors 2019 Study, we analysed mortality and disability-adjusted life-years (DALYs) attributed to transport and unintentional injuries for adolescents in 204 countries. Burden is reported in absolute numbers and age-standardised rates per 100 000 population by sex, age group (10-14, 15-19, and 20-24 years), and sociodemographic index (SDI) with 95% uncertainty intervals (UIs). We report percentage changes in deaths and DALYs between 1990 and 2019. Findings In 2019, 369 061 deaths (of which 214337 [58%] were transport related) and 31.1 million DALYs (of which 16.2 million [52%] were transport related) among adolescents aged 10-24 years were caused by transport and unintentional injuries combined. If compared with other causes, transport and unintentional injuries combined accounted for 25% of deaths and 14% of DALYs in 2019, and showed little improvement from 1990 when such injuries accounted for 26% of adolescent deaths and 17% of adolescent DALYs. Throughout adolescence, transport and unintentional injury fatality rates increased by age group. The unintentional injury burden was higher among males than females for all injury types, except for injuries related to fire, heat, and hot substances, or to adverse effects of medical treatment. From 1990 to 2019, global mortality rates declined by 34.4% (from 17.5 to 11.5 per 100 000) for transport injuries, and by 47.7% (from 15.9 to 8.3 per 100000) for unintentional injuries. However, in low-SDI nations the absolute number of deaths increased (by 80.5% to 42 774 for transport injuries and by 39.4% to 31 961 for unintentional injuries). In the high-SDI quintile in 2010-19, the rate per 100 000 of transport injury DALYs was reduced by 16.7%, from 838 in 2010 to 699 in 2019. This was a substantially slower pace of reduction compared with the 48.5% reduction between 1990 and 2010, from 1626 per 100 000 in 1990 to 838 per 100 000 in 2010. Between 2010 and 2019, the rate of unintentional injury DALYs per 100 000 also remained largely unchanged in high-SDI countries (555 in 2010 vs 554 in 2019; 0.2% reduction). The number and rate of adolescent deaths and DALYs owing to environmental heat and cold exposure increased for the high-SDI quintile during 2010-19. Interpretation As other causes of mortality are addressed, inadequate progress in reducing transport and unintentional injury mortality as a proportion of adolescent deaths becomes apparent. The relative shift in the burden of injury from high-SDI countries to low and low-middle-SDI countries necessitates focused action, including global donor, government, and industry investment in injury prevention. The persisting burden of DALYs related to transport and unintentional injuries indicates a need to prioritise innovative measures for the primary prevention of adolescent injury.

(Afet ve Acil Durum Yonetimi Baskanligi (AFAD), 2024) Ergün, Ruşen; Kutlu, Izzettın; Bekar, İrem
Türkiye’de 06 Şubat 2023 tarihinde yaşanan Kahramanmaraş depremleri, etkili olduğu bölgelerde eğitim süreçlerini uzun süre aksatmıştır. Depremlerin ardından, eğitim amaçlı birçok prefabrik yapı kullanılmaya başlanmıştır. Çalışma, prefabrik eğitim yapılarının sürdürülebilirliğine yönelik öneriler geliştirmeyi amaçlamaktadır. Bu bağlamda sürdürülebilirlik sertifikasyon sistemlerinin değerlendirme kritlerleri ortaya konmuş ve prefabrik Diyarbakır Bağlar Anadolu Lisesi incelenmiştir. Çalışmanın bulguları, prefabrik yapıların malzeme ve kaynak ile iç mekan ortam kalitesi gibi kriterlerde olumlu değerlendirme puanları aldığını ancak enerji ve yenilik kriterleri açısından oldukça zayıf kaldığını göstermiştir. Ayrıca başta gürültü olmak üzere kirlilik kriterine yönelik alınan önlemlerin yetersiz olduğu belirlenmiştir. Çalışmada afet sonrası inşa edilecek prefabrik eğitim binalarına yönelik öneriler sunulmuş ve hızlı bir çözüm sunan prefabrik yapıların, uzun vadeli sürdürülebilirlik hedefleri doğrultusunda kapsamlı değerlendirilmelerinin yapılması gerekliliği sonucuna ulaşılmıştır.
Alpha-lipoic acid may ameliorate testicular damage by targeting dox-induced altered antioxidant parameters, mitofusin-2 and apoptotic gene expression
(Andrologia, 2021) Güzel, Elif Erdem; Kaya Tektemur, Nalan; Tektemur, Ahmet
In the study, the ameliorating effects of alfa lipoic acid (ALA) against doxorubicin-induced testicular apoptosis, oxidative stress and disrupted mitochondrial fusion were investigated in male rats. Rats were divided into four groups as control, doxorubicin (DOX), DOX + ALA and ALA. A single dose of 15 mg/kg DOX was administered i.p to the DOX and DOX + ALA groups. 50 mg/kg ALA was given to the DOX + ALA and ALA groups by oral gavage every other day. After 28 days, rat testes and serum samples were collected and analysed. Administration of DOX alone caused a decrease in body and relative testicular weights, seminiferous tubule diameter and germinal epithelium thickness, Johnsen's score and serum testosterone levels. DOX treatment led to severe testicular damage such as tubular degeneration, and atrophic tubules. Also, the activities of superoxide dismutase and glutathione peroxidase were reduced, while the level of malondialdehyde was increased in the testis. The mRNA levels of apoptotic-related genes (CASP3, TP53, BAX, BCL2) and apoptotic index were increased, while mitofusin-2 decreased. DOX caused an increase in CASP3 and a decrease in mitofusin-2 immunoreactivities. Treatment with ALA markedly improved all of DOX-induced biochemical, histochemical and molecular alterations in rat testis. Consequently, ALA has a therapeutic role in ameliorating DOX-induced testicular damage in rats.
AMMI Model to Assess Durum Wheat Genotypes in Multi-Environment Trials
(JOURNAL OF AGRICULTURAL SCIENCE AND TECHNOLOGY, 2018) Tekdal, S; Kendal, E.
The goal of this research was to assess the stability and yield performance of 150 durum wheat genotypes in multi-environment trials in two locations (Diyarbakir and Kiziltepe), in 2011-2012, and 2012-2013 growing seasons. The trials were designed by Lattice Experimental Design with two replications (incomplete block design). The AMMI (Additive Main Effects and Multiplicative Interaction) and GEI (GenotypexEnvironment Interaction) analysis were used in the study to estimate GEI effects on grain yield, because of plant breeders' great interest in these models for breeding programs. AMMI evaluation indicated that genotypes made the most important contributions to treatments Sum of Squares (59.8%), environments (3.5%), and GEI (36.7%), respectively, suggesting that grain yield had been affected by environment. IPCA 1 and IPCA 2 axes (Principal Component) were significant as P< 0.01 and explained 63.8 and 36.2%, respectively. Results showed that Kiziltepe 2013 was more stable and high yielding, meanwhile Diyarbakir 2012 and Diyarbakir 2013 environments were unstable and low yielding. According to stability variance, usually the province lines were more productive and stable than some old cultivars and many landraces/genotypes. Moreover, genotype G24 was more effective in all environments. The GEI model according to AMMI analysis suggested that this genotype can be considered as a candidate, due to extensive adaptability and high performances in all environments.

(Mdpi, 2024) Tueredi, Sibel; Celik, Hakim; Dagli, Seyda Nur; Taskin, Seyhan; Seker, Ugur; Deniz, Mustafa
The purpose of this study was to reveal the combined effects of propolis (P) and quercetin (Q) against diabetic peripheral neuropathy developing with streptozotocin-induced diabetes in rats. Sixty-four adult male rats were divided into eight equal groups: control, P (100 mg/kg/day), Q (100 mg/kg/day), P + Q (100 mg/day for both), diabetes mellitus (DM) (single-dose 60 mg/kg streptozotocin), DM + P, DM + Q, and DM + P + Q. The rats were sacrificed, and blood and sciatic nerve tissues were collected. Blood glucose and malondialdehyde (MDA) levels increased, while IL-6 and total antioxidant status decreased in the DM group (p = 0.016 and p = 0.047, respectively). Ultrastructural findings showed degeneration of the axon and myelin sheath. The apoptotic index (AI %), TNF-alpha, and IL-1 beta immunopositivity increased significantly in the DM group (p < 0.001). Morphological structures approaching those of the controls were observed in the DM + P, DM + Q, and DM + P + Q groups. Morphometric measurements increased markedly in all treatment groups (p < 0.001), while blood glucose and MDA levels, AI (%), TNF-alpha, and IL-1 beta immunopositivity decreased. In conclusion, the combined effects of propolis and quercetin in diabetic neuropathy may provide optimal morphological protection with neuroprotective effects by reducing hyperglycemia, and these may represent a key alternative supplement in regenerative medicine.
Analyses of Po-Based Fuzzy Logic-Controlled Mppt and Incremental Conductance Mppt Algorithms in Pv Systems
(Mdpi, 2025) Cakmak, Fevzi; Aydogmus, Zafer; Tur, Mehmet Rida
This manuscript aims to increase the utilization of solar energy, which is both environmentally friendly and easily accessible, to satisfy the energy needs of developing countries. In order to achieve this goal, maximum power generation should be provided from photovoltaic panels. Several maximum power point tracking (MPPT) methods are utilized for maximum power generation in photovoltaic panel systems under different weather conditions. In this paper, a novel intelligent hybrid fuzzy logic-controlled maximum power point tracking algorithm founded on the perturb and observe (PO) algorithm is presented. The proposed fuzzy logic controller algorithm and the incremental conductivity maximum power point tracking algorithm were simulated in a MATLAB(2018b version)/Simulink environment and evaluated by comparing the results. Four Sharp ND-F4Q295 solar panels, two in series and two in parallel, were used for the simulation. In this study, the voltage ripple of the proposed hybrid method was measured at 1% compared to the classical incremental conductivity method, while it was 8.6% in the IncCon method. Similarly, the current ripple was 1.08% in the proposed hybrid FLC method, while the current ripple was 9.27% in the IncCon method. It is observed that the proposed smart method stabilizes the system voltage faster, at 25 ms, in the event of sudden weather changes.
Analysis and Mitigation of Power Quality Issues in Distributed Generation Systems Using Custom Power Devices
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2018) Hossain, Eklas; Tur, Mehmet Rida; Padmanaban, Sanjeevikumar; Ay, Selim; Khan, Imtiaj
This paper discusses the power quality issues for distributed generation systems based on renewable energy sources, such as solar and wind energy. A thorough discussion about the power quality issues is conducted here. This paper starts with the power quality issues, followed by discussions of basic standards. A comprehensive study of power quality in power systems, including the systems with dc and renewable sources is done in this paper. Power quality monitoring techniques and possible solutions of the power quality issues for the power systems are elaborately studied. Then, we analyze the methods of mitigation of these problems using custom power devices, such as D-STATCOM, UPQC, UPS, TVSS, DVR, etc., for micro grid systems. For renewable energy systems, STATCOM can be a potential choice due to its several advantages, whereas spinning reserve can enhance the power quality in traditional systems. At Last, we study the power quality in dc systems. Simpler arrangement and higher reliability are two main advantages of the dc systems though it faces other power quality issues, such as instability and poor detection of faults.
An analysis of age-standardized suicide rates in Muslim-majority countries in 2000-2019
(BMC Public Health, 2022) Zeyrek-Rios, Emek Yüce; Bob Lew; Lester, David; Kõlves, Kairi; Yip, Paul S. F.; Ibrahim, Norhayati
Background: This study examines the 20-year trend of suicide in 46 Muslim-majority countries throughout the world and compares their suicide rates and trends with the global average. Ecological-level associations between the proportion of the Muslim population, the age-standardized suicide rates, male-to-female suicide rate ratio, and the Human Development Index (HDI) in 2019 were examined. Methods: Age-standardized suicide rates were extracted from the WHO Global Health Estimates database for the period between 2000 and 2019. The rates in each country were compared with the age-standardized global average during the past 20 years. The countries were further grouped according to their regions/sub-regions to calculate the regional and sub-regional weighted age-standardized suicide rates involving Muslim-majority countries. Correlation analyses were conducted between the proportion of Muslims, age-standardized suicide rate, male: female suicide rate ratio, and the HDI in all countries. Joinpoint regression was used to analyze the age-standardized suicide rates in 2000-2019. Results: The 46 countries retained for analysis included an estimated 1.39 billion Muslims from a total worldwide Muslim population of 1.57 billion. Of these countries, eleven (23.9%) had an age-standardized suicide rate above the global average in 2019. In terms of regional/sub-regional suicide rates, Muslim-majority countries in the Sub-Saharan region recorded the highest weighted average age-standardized suicide rate of 10.02/100,000 population, and Southeastern Asia recorded the lowest rate (2.58/100,000 population). There were significant correlations between the Muslim population proportion and male-to-female rate ratios (r=-0.324, p=0.028), HDI index and age-standardized suicide rates (r=-0.506, p<0.001), and HDI index and male-to-female rate ratios (r=0.503, p<0.001) in 2019. Joinpoint analysis revealed that seven Muslim-majority countries (15.2%) recorded an increase in the average annual percentage change regarding age-standardized suicide rates during 2000-2019. Conclusions: Most Muslim-majority countries had lower age-standardized suicide rates than the global average, which might reflect religious belief and practice or due to Muslim laws in their judicial and social structure which may lead to underreporting. This finding needs further in-depth country and region-specific study with regard to its implication for public policy.

(Taylor & Francis Ltd, 2022) Kizmaz, Veysi
This study was carried out to determine the distribution of total, phospholipid and triacylglycerol fatty acid composition in salted and fresh fish of pearl mullet. Fatty acid analyses were performed in muscle tissues of the fish samples. Eicosapentaenoic acid (EPA), Docosahexaenoic acid (DHA), Omega-3 (n-3), Omega-6 (n-6) which are important for health, were determined in the analyses. The distribution of total and TAG fatty acids in males and females was similar. It was determined that the changes were in the Phospholipid. N-3/n-6 ratio showed a similar distribution in both female and male individuals. In particular, the results obtained may benefit the fisheries industry, nutritionists and researchers, as the nutritional value of the fish is high.
