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.
3D biomechanical analysis of targeted and non-targeted drag flick shooting technique in field hockey
(Drustvo Pedagoga Tjelesne & Zdravstvene Kulture, 2018) Eskiyecek, Canan Gülbin; Bingül, Bergun Meriç; Bulgan, Ciğdem; Aydın, Mensure
The aim of this study was to compare targeted and non-targeted drag flick field hockey shooting techniques in the penalty corner area, using a three-dimensional kinematic analysis. Eleven male field hockey players playing in the super league (mean age: 19,82 +/- 1,40 years) participated voluntarily. Seven high-speed cameras (Oqus 7+) with 120Hz refresh rates were used. Field calibration was completed via the wand method. The data were evaluated in two phases: start and finish. Players undertook three drag flick shots to the box using targeted and non-targeted techniques. The angular kinematics and stroke force applied to the stick were analyzed using the Qualisys Track Manager Program V2.12, and ball velocity statistics were gathered with the SPSS 18.0 program. To compare between the targeted and non-targeted shots of the drag flick shooting techniques, t-test was applied. At the drag flick of the players, significant differences were noticed at the angular speed of the right shoulder and the left knee, and the angular acceleration of the right hip in the starting phase, and also at the right hip angular acceleration at the finish phase. When the ball speed data considered, a significant decrease was observed between the targeted and non-targeted drag flick shots. Significant correlation was found out between some variables, at the angular kinematics and both force applied on the stick and the ball speed values (p <= 0.05). In conclusion, to make an accurate target shot the players maximize their targeted shooting rates, particularly by decreasing the speed of their lower extremities.

Abluted capitalism: Ali Shariati's critique of capitalism in his reading of Islamic Economy
(Sage, 2015) Şengül, Serdar
Islamic sociologist Ali Shariati is a leading figure of the reconstruction of religious thought in the Islamic world known especially for his anti-capitalist stance and leftist reading of Islamic history. In the philosophy of history that he developed, he classified religions as religions of tawheed (unicity of God) and religions of shirk (multiple gods). According to this new reading of history, the main struggle is not between religion and secularism but between religions of tawheed and of sheerk. The issue of the gaining and the distribution of the property is central to his classification. Shariati argued that followers of tawheed and of sheerk can be found in all religions including Islam. To support his argument Shariati explored how capitalistic understanding of Islam has been developed and legalised while anti-capitalist messages and orders of Islam were marginalised and illegalised just after the death of the Prophet Mohammed. He analysed the rivalry between his close companions over the content of a proper Islamic economic order and how this rivalry gave way to two contradicting understanding of Islam, marks of which can be seen today in the contemporary Muslim world. He coined the term abluted capitalism' to define the economic policies of Muslim sovereigns to make Islam compatible with capitalist economic principles.
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.
Activity of nanosized copper-boron alloys against Phytophthora species
(Springer Science and Business Media Deutschland GmbH, 2023) Yiğit, Uğur; Türkkan, Muharrem; İlhan, Hasan; Şimşek, Tuncay; Güler, Ömer; Derviş, Sibel
This study aimed to evaluate the antifungal activity of copper-boron (Cu-B) nanoalloys against a range of Phytophthora species, including P. capsici, P. citrophthora, P. palmivora, P. cinnamomi, P. nicotianae, P. cactorum, P. plurivora, P. inundata, and P. megasperma. The nanoalloys were synthesized via mechanical alloying under an argon atmosphere, resulting in the formation of nanocrystalline Cu-B nanoalloys with irregular morphology and particle sizes ranging from 50 to 240 nm. At a concentration of 250 µg mL−1, the Cu-B nanoalloys demonstrated complete inhibition of mycelial growth, sporangium production, and zoospore germination in all tested Phytophthora species. The EC50 values for mycelial growth ranged from 28.02 to 120.17 µg mL−1, while for sporangium production and zoospore germination, they were below 10 µg mL−1. Furthermore, the nanoalloys exhibited fungicidal activity against specific Phytophthora species, such as P. capsici, P. citrophthora, P. inundata, and P. megasperma, at concentrations of 100, 250, 250, and 250 µg mL−1, respectively. Notably, the Cu-B nanoalloys displayed significant protective and curative effects on tuber rot severity in P. nicotianae-inoculated potatoes, resulting in reductions of 94.13% and 92.61% compared to the control, respectively, at a concentration of 10 µg mL−1 (P < 0.05). These findings highlight the potential of Cu-B nanoalloys as a promising fungicide for the management of plant diseases caused by Phytophthora spp.

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 .

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
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.

Adsorption and inhibition effect of 2,4-diamino-6-hydroxypyrimidine for mild steel corrosion in HCl medium: experimental and theoretical investigation
(SPRINGER HEIDELBERG, 2019) Yildiz, Resit; Yıldız, Reşit
2,4-Diamino-6-hydroxypyrimidine (2D6H) was examined as corrosion inhibitor of mild steel (MS) in 0.1M HCl using potentiodynamic measurements, linear polarization resistance (LPR), scanning electron microscopy, electrochemical experiments, and quantum chemical calculations. All measurements show that the corrosion inhibition effectiveness is forthright compared to the concentration of 2D6H ranging from 0.5 to 10.0mM. Adsorption of 2D6H on the MS surface in the presence of HCl is determined to obey Langmuir adsorption isotherm. The electronic features elucidated by quantum chemical calculations were associated with the experimental inhibition productivities. The mechanism of inhibition was revealed by E-pzc measurements.

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.

(Environmental Progress & Sustainable Energy, 2023) Baran, Ayşe; Dal, Mehmet Can; Onursal, Nilgün; Altunkaynak, Yalçın
This paper evaluates Malatya clay (MC) for the removal of Ni(II) ions from aqueous solutions. For adsorption efficiency, the impacts of several factors, such as pH, starting metal ion concentration, and contact duration, were examined. The optimal initial Ni(II) ion concentration was determined to be 5 mg/L, the adsorption contact duration was 360 min, and the solution's pH was 6.27. Using scanning electron microscopy, energy dispersive spectroscopy, and Fourier transform infrared spectroscopy, the surface characteristics of Malatya clay were examined. The isotherm data fit the Langmuir isotherm model, indicating chemical adsorption and likely irreversibility of the process, according to the results. At 298, 308, and 318 K, the adsorption capacities of Ni(II) were determined to be 10.267, 11.834, and 12.285 mg/g, respectively. Adsorption kinetic data revealed that the adsorption of Ni(II) metal ions followed the pseudosecond-order kinetic model. According to thermodynamic studies, Ni(II) ion adsorption on the MC is spontaneous and endothermic. MC has proven to be an effective and alternative material for the removal of Ni(II) ions from aqueous media due to its excellent removal ability, availability, and low cost, as well as its features such as being able to be used without any chemical treatment and being environmentally friendly.

(Taylor & Francis Ltd, 2022) Baran, M. Firat; Yildirim, Ayfer; Acay, Hilal; Keskin, Cumali; Aygun, Husamettin
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.
