Metals and phosphorus in the sediments of streams emptying into the Çanakkale strait (Dardanelles): Spatial distribution, pollution status, risk assessment and source identification
(Academic Press Inc Elsevier Science, 2024) Varol, Memet; Tokatli, Cem
The & Ccedil;anakkale Strait is exposed to various pollutants due to its strategic location. It is thought that stream inputs may contribute significantly to metal and phosphorus (P) accumulation in the strait. In this study, the spatial distribution, pollution status, ecological risks and possible sources of twelve metals and P in the sediments of seven important streams emptying into the strait were analyzed. The results showed that Zn (226 mg/kg), Ba (67.2 mg/kg) and Pb (10.4 mg/kg) concentrations were higher in the Umurbey Stream due to mining activities, while P concentration (295 mg/kg) was higher in the & Ccedil;anakkale Stream due to both agricultural activities and domestic wastewater discharges. Modified hazard quotient (mHQ), enrichment factor (EF) and contamination factor (Cf) values revealed that Zn and Pb showed high and moderate contamination in the US3 and US4 sampling sites of the Umurbey Stream, respectively. Similarly, P showed moderate contamination in the & Ccedil;S3 site of the & Ccedil;anakkale Stream. Nemerow pollution index (NPI) showed that the US3 (2.41) and US4 (4.28) sites of the Umurbey Stream were slightly and moderately polluted, respectively. Toxic risk index (TRI) values demonstrated that the sediments in only the US4 site (5.17) of the Umurbey Stream may pose a low toxic risk due to high Zn content. Similarly, based on comparison results with sediment quality guidelines (SQGs), it was found that high Zn content may lead to adverse effects on sediment-dwelling organisms in the US4 site. In addition, the PECquotient value in the US4 site exceeded 0.5, confirming the finding that the sediments in this site could be toxic to benthic organisms. Finally, correlation, cluster and factor analyzes were used to determine possible sources of elements. Mining activities, natural sources and mixed sources (agricultural activities and natural sources) were identified as the main sources of elements in the sediments of the streams. This study can provide an important reference for evaluating stream sediment pollution and managing marine pollution.
Mesleki ve Teknik Lise Öğrencilerinin Siber Aylaklık Düzeylerinin Farklı Değişkenlere Göre İncelenmesi
(2018) Gezgin, Deniz Mertkan; Arslantaş, Tuğba Kamalı; Şumuer, Evren
Bu çalışmanın amacı, mesleki ve teknik lise öğrencilerinin siber aylaklık düzeylerinin cinsiyet, sınıf, kullanılan sosyal medya hesabı sayısı, derslerde kullanılan cihaz türü ve sosyal medyayı kontrol etme sıklıkları açısından farklılaşıp farklılaşmadığını incelemektir. Çalışmanın katılımcılarını Mesleki ve Teknik Lisede Bilişim Teknolojileri alanında öğrenim gören, mesleki derslerinde bilgisa yara erişimi olan ve derslerinde mobil telefonlarını serbest bir şekilde kullanan 145 öğrenci oluşturmaktadır. Çalışmanın verileri Siber Aylaklık Ölçeği ve demografik bilgi formu kullanılarak toplanmıştır. Verilerin analizinde bağımsız örneklem t -testi ve tek yönlü varyans analizinden (ANOVA) yararlanılmıştır. Bulgular incelendiğinde, öğrencilerin siber aylaklık düzeylerinde cinsiyet ve öğrenim görülen sınıfa göre istatistiksel olarak anlamlı bir farklılık bulunmazken, derste yoğun olarak kullanılan cihaz türüne göre istatistiksel olarak anlamlı bir fark bulunmuştur. Ayrıca bulgular, öğrencilerin siber aylaklık düzeylerinin takip ettikleri sosyal medya hesabı sayısı ve sosyal medyayı kontrol etme sıklığına göre istatistiksel olarak anlamlı bir şekilde farklılaştığını göstermektedir. Bu sonuçlar, akıllı telefon ve sosyal medya kullanımının mesleki ve teknik lise öğrencilerinin siber aylaklık davranışları üzerinde etkisi olduğunu göstermektedir. Çalışmada öğrencilerin siber aylaklık davranışlarının azaltılmasına ve ileride siber aylaklık üzerine araştırma yürütecek araştırmacılara yönelik bazı öneriler sunulmuştur.
Translation Decisions and Methods in Paratranslation of Textless Back Translations
(2020) Taş, Seda
This article intends to scrutinize various translation decisions of translators and editors intranslating a text back to its culture through a case study of textless back translations of TheGrande Turke Süleyman the Magnificent, Sultan of the Ottomans. It also makes an attempt toexplore how the traditional distinction between domestication and foreignization translationmethods might vary in these texts with a special reference to paratranslation. Paratranslation,coined as a term by a Translation and Paratranslation (T&P) research group at the University ofVigo, developed by Yuste Frías (2012, 2015) and already used in the research of translation studiesfor a while, is worthy of special attention for it enables to re-evaluate translation methods and reemphasize how translation decisions might become diversified. The source text at the focal pointof the study is considered to have a crucial place in Turkish history and culture for it narrates thetenth Sultan of the Ottoman Empire, Süleyman’s life from birth to death in detail. It was writtenby the English writer Fairfax Downey (1893-1990) in 1929 and translated into Turkish three timesby different translators. The source text and textless back translations, known as a specific kind ofback translation, have been analyzed comparatively in terms of paratranslation within the scopeof this study since the texts included the addition of abundant paratextual elements. The findingshave shown that paratranslations employed in the source texts’ repatriations allow to pinpointdifferent translation agents’ authorial or interventionist decisions in textless back translations.Additionally, the present study has witnessed that “re-domestication” as a more distincttranslation method might be employed in different cases of translation such as textless backtranslations.
On the behavior of single-particle dynamic properties of liquid Hg and other metals
(Amer Inst Physics, 2008) Gonzalez, Luis E.; Gonzalez, David J.; Calderin, Lÿzaro; Sengul, Sedat
Recent experiments and classical molecular dynamics simulations performed on liquid Hg near melting have suggested the existence of two processes with different time scales in its single-particle dynamics. We report a study of this system by using ab initio molecular dynamics simulations, which recover the same kind of behavior, and we analyze it in terms of a theoretical approach, which clarifies its origin. We show that the previous interpretation has been induced by the unphysical extension of the diffusive model to short times. Moreover, we also find that quite different liquid metals, such as Si and Mg, also exhibit a similar behavior as Hg, with the only difference being in the time scales involved due to the different masses and interactions.
Revisiting Classical 3?-hydroxysteroid Dehydrogenase 2 Deficiency: Lessons from 31 Pediatric Cases
(Endocrine Soc, 2020) Guran, Tulay; Kara, Cengiz; Yildiz, Melek; Bitkin, Eda C.; Haklar, Goncagul; Lin, Jen-Chieh; Keskin, Mehmet
Context: The clinical effects of classical 3 beta-hydroxysteroid dehydrogenase 2 (3 beta HSD2) deficiency are insufficiently defined due to a limited number of published cases. Objective: To evaluate an integrated steroid metabolome and the short- and long-term clinical features of 3 beta HSD2 deficiency. Design: Multicenter, cross-sectional study. Setting: Nine tertiary pediatric endocrinology clinics across Turkey. Patients: Children with clinical diagnosis of 3 beta HSD2 deficiency. Main Outcome Measures: Clinical manifestations, genotype-phenotype-metabolomic relations. A structured questionnaire was used to evaluate the data of patients with clinical 3 beta HSD2 deficiency. Genetic analysis of HSD3B2 was performed using Sanger sequencing. Novel HSD3B2 mutations were studied in vitro. Nineteen plasma adrenal steroids were measured using LC-MS/MS. Results: Eleven homozygous HSD3B2 mutations (6 novel) were identified in 31 children (19 male/12 female; mean age: 6.6 +/- 5.1 yrs). The patients with homozygous pathogenic HSD3B2 missense variants of > 5% of wild type 3 beta HSD2 activity in vitro had a non-salt-losing clinical phenotype. Ambiguous genitalia was an invariable feature of all genetic males, whereas only 1 of 12 female patients presented with virilized genitalia. Premature pubarche was observed in 78% of patients. In adolescence, menstrual irregularities and polycystic ovaries in females and adrenal rest tumors and gonadal failure in males were observed. Conclusions: Genetically-documented 3 beta HSD2 deficiency includes salt-losing and non-salt-losing clinical phenotypes. Spared mineralocorticoid function and unvirilized genitalia in females may lead to misdiagnosis and underestimation of the frequency of 3 beta HSD2 deficiency. High baseline 17OHPreg to cortisol ratio and low 11-oxyandrogen concentrations by LC-MS/MS unequivocally identifies patients with 3 beta HSD2 deficiency.
