Prime necessity of the mothers were informed about the right applications.
19. Yüzyıl Vanı’nda Âyan Bir Aile: Timurpaşazâdeler
(2022) Çiftçi, Erdal
Bu çalışma 18. yüzyılın son çeyreğinden 19. yüzyılın ortasına kadar Van yönetiminde bulunan ve bu tarihten sonra da Van’da etkili olmaya devam eden ayan bir ailenin yerel siyasetteki rolüne odaklanmaktadır. Ayanlar çağı olarak bilinen 18. yüzyılda Osmanlı imparatorluğunda güçlenmiş olan ayanlarla ilgili literatüre mikro bir çalışma ile Van örneği üzerinden katkı sunulması amaçlanmaktadır. Van’da Timurpaşazadeler ismi ile ayanlaşan bir ailenin güçlenerek ortaya çıkışı, Tanzimat öncesi ve sırasında yaşanan tepkiler ve Tanzimat sonrasında bu ayan ailenin yeni düzen içerisindeki aktif yer alışı incelenmektedir. Tanzimat düzeninin bu gibi ayan aileleri yaptırımcı, tek taraflı ve üstten bir yaklaşımla izale ederek uygulamaya dökülebildiği görüşü son dönemlere kadar literatürün baskın tezlerinden biriydi. Fakat son dönemlerde yapılan yeni çalışmalardan ve Van örneğinden de görüleceği üzere Tanzimat merkezileşmesi yerel ayan ailelerin mülki idari güçlerine belirli oranda bir sınır uygulamış olsa da Timurpaşazadeler yeni düzenin uygulanmasında aktif rol oynamaya devam etmişlerdir. Timurpaşazadelerin bir eşraf olarak kendi rol ve çıkarlarını yeni düzen içerisinde aramaya devam ettikleri anlaşılmaktadır. Dersaadet’in Timurpaşazadeleri Van’dan kaldırmamış olması ve Timurpaşazadelerin bazı Van valileri ile yakın ilişkilerini sürdürmesi bu durumun önünü açan sebeplerden birkaçıdır.

Ability of Cha2ds2-vasc/R2cha2ds2-vasc Scores To Predict Complications Related To Cardiac Implantable Electronic Devices
(John Wiley and Sons Inc, 2025) Söner, S.; Aktan, A.; Kılıç, R.; Güzel, H.; Taştan, E.; Okşul, M.; Güzel, T.
Background: Globally, the number of cardiac implantable electronic devices (CIEDs) is increasing. In our study, we aimed to investigate whether CHA2DS2-VASc and R2CHA2DS2-VASc scores are predictive of CIED-related complications. Methods: Our investigation was carried out with a multicenter retrospective design. Patients who underwent CIED surgery at two cardiac centers in Turkey between January 2011 and May 2023, 1676, were evaluated. The patients were divided into two groups according to their R2CHA2DS2-VASc scores. Patients with R2CHA2DS2-VASc ≥ 5 were included in group 1 (380 patients), and patients with R2CHA2DS2-VASc < 5 (1296 patients) were included in group 2. The primary outcome was defined as the cumulative events. Each component of cumulative events, such as hematoma, pericardial effusion, pneumothorax, and infection, was also defined as a secondary outcome. Results: The study's patient population had an average age of 62.9 ± 14 years. Pneumothorax (1.8% vs. 1.3%, p = 0.444), pericardial effusion or tamponade (0.35% vs. 0.2%, p = 0.659), and clinically significant hematoma (1.1% vs. 0.6%, p = 0.376) were comparable between the groups. Infection-related devices and cumulative events classified as primary outcomes were higher in the R2CHA2DS2-VASc ≥ 5 group (6.1% vs. 1.2%, p < 0.001; 7.6% vs. 3.2%, p < 0.001, respectively). Modeling analyses showed that the CHA2DS2-VASc score and HT were also independent predictors of device-related infection and cumulative events. Conclusion: In the R2CHA2DS2-VASc ≥ 5 groups, infection related to the device system and cumulative events were higher. Patients with an R2CHA2DS2-VASc score of 5 or more and a high CHA2DS2-VASc score should be evaluated more carefully regarding infection and cumulative events before and after the operation. © 2025 Wiley Periodicals LLC.
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.

Açık Bir Ekonomide Toplam İstikrarsızlığın Test Edilmesi
(2022) Yılmaz, Yusuf Ömür
Bu makale, alternatif para politikası kuralları altında pozitif uzun vadeli enflasyon oranı ve güneş lekesi şoku içeren küçük bir açık ekonomi Yeni-Keynesyen modeli kullanarak 2010 ve 2016 yılları arasında Türk ekonomisinin istikrarını ampirik olarak test etmektedir. Belirsizlik olasılıklarının bire çok yakın olduğu bulunmuştur. Bu dönemde ekonominin istikrarsız olduğu sonucuna varılabilir çünkü Merkez Bankası'nın enflasyona zayıf tepki vermesine rağmen uzun vadeli enflasyon oranı yüksek tek hanelidir. Bu durum ekonomiyi genel istikrarsızlığa sürüklemiştir.
Acil Servis Kalabalıklığının Nedenleri ve Çözüm Önerileri: Sağlık Personeli Perspektiflerinin Nitel Bir Çalışması
(2023) Bütün, Ahmet
Giriş: Acil servislerin aşırı kalabalıklığı küresel bir sorundur. Bu durum uzun bekleme süresi, hastaların ve sağlık personelinin memnuniyetinin azalması, acil bakıma en çok ihtiyaç duyan hastaların tedavisinin gecikmesi, sağlanan sağlık hizmetinin kalitesinin düşmesi ve sağlık bakım maliyetlerinin artması gibi birçok olumsuz sonuca yol açmaktadır. Bu çalışmanın amacı, hastaların acil servisleri neden kullanmayı tercih ettiklerini, acil sağlık hizmetlerinin güncel sorunlarını belirlemek ve acil servislerin kalabalıklığını ve buna bağlı sorunları hafifletmek için acil servis sağlık personelinin bakış açılarından çözüm geliştirmektir. Yöntem: Bu çalışmada nitel desen kullanılmıştır. 20 Aralık 2021-18 Şubat 2022 tarihleri arasında 22 acil servis sağlık personeli ile derinlemesine yarı yapılandırılmış görüşmeler gerçekleştirilmiştir. Verilerin analizinde tematik analiz yöntemi kullanılmıştır. Bulgular: 22 acil servis sağlık personeli ile mülakat yapıldı; 16'sı erkek, 6'sı kadındı. Acil servis sağlık personeli görüşmeleri, acil serviste en az 1 yıllık iş deneyimine sahip 14 acil servis hemşiresi, 6 acil servis doktoru ve 2 acil tıp uzmanı ile cinsiyetleri veya yaşları dikkate alınmadan gerçekleştirilmiştir. Veri analizi sonucunda 5 ana tema belirlenmiştir: Yetersiz sağlık sistemi, hastayla ilgili sorunlar, acil servislerin avantajları, acil servislerin aşırı kalabalıklığının sonuçları ve acil servis kalabalıklığı için çözümler. Sonuç: Sağlık sistemindeki çeşitli yetersizlikler, acil servislerin avantajlarının olması ve hastaların sağlık hizmetlerini kullanma konusundaki algıları acil servislerin hastalar tarafından kullanımını arttırmış ve bu durum acil servislerde kalabalıklaşmaya sebep olmuştur. Acil servislerin kalabalıklığını hafifletmek için etkili çözümlere ihtiyaç vardır. Acil olmayan acil servis ziyaretlerini azaltmaya yönelik önlemler yeterli değildir. Acil servislerdeki kalabalıklığı azaltmak için birçok faktörün göz önünde bulundurulması ve hepsinin birlikte uygulanması gerekmektedir.
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.

Acute Cyanide Intoxication Due To Apricot Seed Ingestion
(Soc Argentina Pediatria, 2024) Talay, Mehmet N.; Gungor, Emre; Orhan, Ozhan
Introduction : Cyanide poisoning, whether it be accidental or intentional, remains a significant danger to adults and children, especially in societies where agriculture is a primary source of income. We examined the clinical follow-up, complications, and results of cyanide poisoning cases that occurred after eating the pits and seeds of plants containing cyanide glycosides, such as apricot kernels and almonds. Methods : Between 01/01/2017 and 01/08/2022, 14 children aged 1-18 years who were followed up with a prediagnosis of cyanide poisoning in our Paediatric Intensive Care Unit (PICU) were retrospectively analysed. Results : Eight of the patients followed with a preliminary diagnosis of cyanide poisoning were female and six were male. The most common admission month was July (42.8%) coinciding with the agricultural season. The most common symptoms at presentation were weakness and fatigue (n = 7). In the PICU, 4 patients presented lip cyanosis; 3, altered level of consciousness. Vomiting, seizure, headache, dizziness and palpitatons were less frequent. Four patients were treated with hydroxocobalamin (Cyanokit (R) ) as an antidote due to acidosis in their blood gases. All patients treated for cyanide poisoning were discharged. Conclusions : Cyanide poisoning should be considered in paediatric patients with suspicious findings, sudden loss of consciousness, increased anion gap acidosis and lactic acidosis. The history of eating the seeds of plants such as apricot and almonds should be investigated .

Acute Toxicity of Deltamethrin on the Fatty Acid Composition of Phospholipid Classes in Liver and Gill Tissues of Nile Tilapia
(Springer International Publishing, 2017) Cengiz, E.I.; Bayar, A.S.; Kızmaz, V.; Başhan, M.; Satar, A.
Deltamethrin is a pyrethroid pesticide contaminating aquatic ecosystems. The purpose of this study was to clarify the acute toxicity of deltamethrin on the fatty acids of phospholipid (PL) classes in liver and gill of Nile tilapia. The fatty acids of PL classes were analyzed by gas chromatography. Deltamethrin brought about differences in the fatty acids of the PL classes in the liver and gill. In the liver of exposed fish, 16:0, 18:2(n-6), 22:6(n-3) in phosphatidylcholine (PC); 16:0, 18:1(n-9), 18:2(n-6), 20:4(n-6), 22:6(n-3) in phosphatidylethanolamine (PE); 16:0, 18:0, 18:1(n-9), 20:4(n-6), 22:6(n-3) in phosphatidylinositol (PI) and in phosphatidylserine (PS) 16:0, 18:1(n-9), 20:4(n-6), 22:6(n-3) were the affected fatty acids. There were significant alterations in ∑MUFAs (monounsaturated fatty acids), ∑(n-3)PUFAs (polyunsaturated fatty acids) and ∑(n-6)PUFAs in PC; ∑SFAs (saturated fatty acids), ∑MUFAs, ∑PUFAs, ∑(n-3)PUFAs and ∑(n-6)PUFAs in PE; ∑SFAs, ∑MUFAs, ∑(n-3)PUFAs and ∑(n-6)PUFAs in PI and ∑SFAs, ∑MUFAs, ∑PUFAs and ∑(n-3)PUFAs in PS. In the gill, 18:2(n-6), 20:4(n-6), 22:6(n-3) in PC; 16:0, 18:1(n-9), 20:4(n-6), 22:6(n-3) in PE; 16:0, 18:0, 18:1(n-9), 18:2(n-6) in PI and in PS 16:0, 18:0,18:1(n-9), 20:3(n-6), 20:5(n-3), 22:6(n-3) affected. The alterations in ∑SFAs, ∑MUFAs, ∑PUFAs and ∑(n-6)PUFAs in PC; ∑SFAs, ∑MUFAs, ∑PUFAs, ∑(n-3)PUFAs and ∑(n-6)PUFAs in PE; ∑(n-3)PUFAs and ∑(n-6)PUFAs in PI; ∑SFAs, ∑MUFAs, ∑PUFAs, ∑(n-3) PUFAs and ∑(n-6)PUFAs in PS were significant in gill. The changes in the fatty acids of the PL classes in response to deltamethrin can influence structure and functions of the membrane systems. Changes in fatty acids may be one defense mechanism against the deltamethrin. © 2017, University of Tehran.
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).
Adaptation of the Vicarious Resilience Scale To Turkish: a Validity and Reliability Study
(American Psychological Association, 2025) Topçu, F.; Boz, C.; Şeneldir-Patolo, A.; Kitapçıoğlu, S.; Işıker-Bedir, D.; Sanyar, S.
Objective: The 27-item Vicarious Resilience Scale (VRS) is the first tool developed to measure vicarious resilience in mental health professionals working with trauma survivors. Given that the VRS measures the positive impact on therapists resulting from observing the healing process of trauma victims, it is especially significant to evaluate its validity and reliability in Turkish culture. This study aims to adapt the VRS to Turkish and examine its psychometric properties. Method: VRS was adapted and administered via electronic survey to 337 mental health professionals from around the globe working with survivors of severe traumas, such as earthquake survivors. The validity of the VRS was examined using different techniques: confirmatory factor analysis (CFA) and criterion-related validity. Results: CFA yielded seven factors that were consistent with the original form: changes in life goals and perspective, client-inspired hope, increased recognition of clients’ spirituality as a therapeutic resource, increased capacity for resourcefulness, increased self-awareness and self-care practices, increased consciousness of power and privilege relative to clients’ social location, and increased capacity for remaining present while listening to trauma narratives. The Cronbach’s α reliability of the VRS was found to be.95; it displayed positive correlations with posttraumatic growth, psychological resilience, and quality of life, indicating convergent validity. However, it had a negative correlation with depression, anxiety, and stress, indicating discriminant validity. Conclusion: The VRS is a valid and reliable measurement scale by professionals working with trauma survivors to aid the recognition and cultivation of vicarious resilience in Turkish mental health professionals. © 2025 American Psychological Association
Adm and Sflt-1 Expression in Placentas With Gestational Diabetes Mellitus
(2023) Söker, Sevda İpek; Aşır, Fırat; Deveci, Engin; Arslan, Necat; Kaplan, Özge; Şeker, Uğur; Başaran, Süreyya Özdemir
Amaç: Bu çalışmada gestasyonel diyabetes mellitusta (GDM) vasküler regülasyonda rolü saptanan iki yeni protein olan Adrenomedullin (ADM) ve soluble fms-benzeri tirozin kinaz (sFlt-1)’in ekspresyon seviyelerini incelemeyi, hastalığın histopatolojisinde bu proteinlerin ekspresyon seviyelerini karşılaştırmayı ve bu proteinlerin ekspresyon yoğunluğunun hastalıkla korelasyonunu gözlemlemeyi amaçladık. Gereç ve Yöntem: Çalışmamızda 20 Normotansif ve 20 GDM’li plasenta örneği alındı. Histolojik takip yöntemiyle takip edildi. Bu dokulardan 5µm kalınlığında kesitler alınarak Hematoksilen-Eozin, Periodic Acid Schiff (PAS) boyamaları yapıldı. İmmunünohistokimyasal olarak ADM ve sFlt-1 antikorları çalışıldı. Bulgular: GDM grubunda; kök villuslarındaki kan damarlarında dilatasyon ve konjesyon, endotel hücrelerinde hiperplazi görüldü. Villusların dış kısmındaki sinsitiyal köprülerde artış, mononükleer hücre infiltrasyonu, maternal bölgedeki desidual hücrelerin bazılarında piknotik nükleuslar ve sitoplazma kaybı izlendi. İmmunohistokimyasal incelemede villusların sitotrofoblast ve sinsitiyotrofoblast hücrelerinde ve sinsitiyal düğümlerde negatif ADM ekspresyonu vardı. Küçük villusların bazı sitotrofoblast hücrelerinde, damar endotel hücrelerinde ve desidual hücrelerde pozitif ADM ekspresyonu görüldü. GDM grubunda sFlt-1 ekspresyonu endotel hücrelerinde, mezenşimal bağ doku içindeki bazı Hofbauer hücrelerinde, desidual hücre nükleuslarında ve membranlarında pozitif olarak gözlendi. Sonuç: Desidual hücre membranlarında, sitotrofoblastlarda ADM pozitif ekspresyon gösterdiğinden ADM’nin glikoz yoğunluğunun belirlenmesinde ve bununla ilişkili olarak insülin regülasyonunda önemli bir düzenleyici olabileceğini düşündürmüştür. Yine sFlt-1’in maternal ve fötal bölgelerdeki endotel hücresi üzerindeki etkileri ve Hofbauer hücrelerindeki ekspresyonu, anjiyogenik etkide bu molekülün anahtar rol alabileceği kanısını uyandırmıştır.
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.

(Emerald Group Publishing Ltd, 2023) Okten, Veysi; Yildiz, Resit; Sigircik, Goekmen; Yıldız, Reşit
PurposeThis study aims to prevent mild steel (MS) against corrosion in 0.5 M HCl solution, 2-amino-4-methoxy-6-methyl-1,3,5-triazine was used. The effectiveness of the compound as a corrosion inhibitor was studied via electrochemical, surface and theoretical calculation techniques. Design/methodology/approachFor concentrations ranging from 0.5 to 10.0 mM, almost similar polarization resistances were obtained from electrochemical impedance spectroscopy (EIS) and linear polarization resistance tests. It also investigated inhibitive activity of 2-amino-4-methoxy-6-methyl-1,3,5-triazine on the steel surface using scanning electron and atomic force microscope instruments. Langmuir adsorption is the best matched isotherm for the adsorption of the inhibitor to the steel surface. FindingsEIS method was used to determine inhibition efficiency, which was determined to be 95.7% for 10.0 mM inhibitor containing acid solution. Density functional theory's predictions for quantum chemistry agreed well with the other experimental results. Originality/valueThe methods used in this study are effective and applicable; the used organic inhibitor is 2-amino-4-methoxy-6-methyl-1,3,5-triazine; and protective effectiveness is important, which is crucial for the task of MS corrosion prevention.
Adsorption of Crystal Violet Dye With Selenium Nanoparticles Obtained by Green Synthesis From Cherry (prunus Avium L.) Fruit Stalk
(2024) Solmaz, Alper; Turna, Talip; Baran, Ayşe
The rapid development of the global production printing and dyeing industry has led to an increase in the demand for various dyes. Crystal violet (CV), a versatile dye, is widely used in the textile industry and other applications. The reason for its widespread use is its effectiveness and the vivid color it gives to fabrics.CV dye is a water-soluble, toxic, resistant organic dye that is quite dangerous for the ecosystem and causes environmental pollution. Therefore, it must be removed before being released into the recipient environment. This study synthesized selenium nanoparticles (Se NPs) from agricultural Prunus avium L. (PaL.) wastes and removed CV dye. In batch adsorption tests, the effects of pH, amount of adsorbent, time, initial concentration, and temperature were investigated. In this study, where 3 different kinetic and isotherm models were tested, it was determined that the most suitable kinetic and isotherm models for the removal of CV dye with PaL-Se NPs were Pseudo second order (R2:0.999) and Langmuir (R2:0.997), respectively. Additionally, the maximum adsorption capacity (qmax) was calculated as 142.61 mgCV/g PaL-Se NP. Accordingly, it can be said that low-cost PaL-Se NPs synthesized by environmentally friendly methods are a suitable alternative for the removal of CV dye.

Mercury is known to be one of the most toxic heavy metals in the environment and is released into the water systems in significant quantities through natural events and industrial process activities. Many chemical materials are used as adsorbents in the removal of toxic metals from the environment and wastewaters. However, using microorganisms as bio-sorbents instead of chemical materials has become common recently due to their low cost, easy availability and presence in nature. In this study, Bacillus licheniformis in the soil isolated from the Tigris River was used as bio-sorbent. The mercury (Hg(II)) absorption behaviour of Bacillus licheniformis bacteria (BLB) was investigated using inductively coupled plasma mass spectrometry. The effects of equilibrium of adsorption time, temperature, adsorbent dosage and pH on the adsorption of Hg (II) onto BLB were determined. The maximum adsorption capacity of Hg (II) onto BLB was determined as 82.12 mg/g (T = 25 degrees C, pH 5, Co = 50 mg/L, m = 25 mg). The BLB was characterised using Fourier transform infrared spectroscopy analysis, thermal gravimetric analysis/differential thermal analysis, scanning electron microscopy analysis and energy-dispersive X-ray spectroscopy analysis. In addition, pseudo-first-order and pseudo-second-order kinetic models were applied. The equilibrium data for the adsorption of Hg(II) onto BLB were examined by the Langmuir and Freundlich isotherm models. The activation energy was calculated using the pseudo-second-order rate constant. These results suggested the BLB can be used as an efficient adsorbent for the removal of Hg(II) metal ions from wastewater. When the results of bio-sorption studies were examined, it was found that the bio-sorbent could be reused easily. The present study suggests that microorganism bio-sorbents are useful for the efficient removal of mercury from aqueous solutions.
Adsorptive Removal Of Cationic Dye From Aqueous Solutions Using Bardakçı Clay
(2022) Alacabey, İhsan
This study was investigation employed the batch adsorption method using Bardakçı Clay/Van as an adsorbent to remove crystal violent, a cationic dye from an aqueous solution. The effects of pH, adsorbent amount, interaction time and concentration were investigated to determine the optimal adsorption conditions. The optimal adsorption conditions were determined to be pH=6, 0.6 g adsorbent amount, and the adsorption reached equilibrium at the 25th minute. The equilibrium isotherm was determined using the Langmuir, Freundlich and Dubinin–Radushkevich (D–R) adsorption equations. It was discovered to conform to the Langmuir isotherm. In the Dubinin-Radushkevich (D-R) model, the E value was calculated to E< 8 kJmol-1, indicating that the adsorption process occurs physically. Thermodynamic parameters such as enthalpy (ΔHo), Gibbs' free energy (ΔGo) and entropy (ΔSo) were calculated. The adsorption of crystal violet with Bardakçı clay demonstrated that the process was endothermic, occurring both physically and spontaneously.
