    Eocene magmatism related to postcollisional extension in the Eastern Pontides (NE Turkiye): 40Ar-39Ar geochronology, geochemistry, and whole-rock Sr-Nd-Pb-Hf isotopes

    Aydinçakir, Emre; Yücel, Cem; Kaygusuz, Abdullah; Bilici, Ozgur; Yilmazer, Sinan; Ruffet, Gilles

    The mineral chemistry, whole-rock geochemistry, 40 Ar / 39 Ar dating and Sr-Nd-Pb-Hf isotopes of the Eocene Narman (Erzurum) Volcanic rocks in the southeast of the Eastern Pontides Orogenic Belt (EPOB, NE Turkiye) were investigated. The Narman Volcanites consist of basaltic dyke, basaltic lava, and basaltic volcanic breccia facies. Volcanites contain plagioclase (An34-80), 34-80 ), clinopyroxene (Wo38- 38- 47En41-50Fs5-18), En 41-50 Fs 5-18 ), and olivine (Fo 68-90 ) as phenocrystals with magnetite/titanomagnetite microphenocrysts. New 40 Ar- 39 Ar ages suggest that these volcanic rocks erupted between 44.5 +/- 0.1 and 43.4 +/- 0.1 Ma, within the Middle Eocene (Lutetian). Narman Volcanites have calcalkaline character, with medium-high K content. Volcanites are enriched in large ion lithophile elements (LILE) and light rare earth elements (LREE), while they are depleted in terms of high field strength elements (HFSE). Chondrite-normalized rare earth element distributions have concave shape with moderate enrichment (LaN/LuN= N /Lu N = 2.78-7.99), leading to consideration that the magmas forming the volcanics derived from similar sources. Isotopically, the rocks in the Narman Volcanites have low-medium initial 87 Sr/ 86 Sr values (0.70405-0.70485), initial 143 Nd/ 144 Nd values (0.512606-0.512848) and positive Nd i (+0.5 - +5.2). Depleted mantle Nd model ages were T DM1 = 0.29-0.62 Ga and T DM2 =0.43-0.83 Ga. (206Pb/204Pb)i, 206 Pb/ 204 Pb) i , (207Pb/204Pb)i, 207 Pb/ 204 Pb) i , and (208Pb/204Pb)i 208 Pb/ 204 Pb) i values vary in the ranges of 18.246-18.709, 15.578-15.616, and 38.225-38.791, respectively. The initial (176Hf/177Hf)i 176 Hf/ 177 Hf) i ratios for the volcanites are between 0.282770 and 0.283013, while the epsilon Hf values range from +7.6 to +9. All the evidence supports the conclusion that the parental magma for the rocks probably derived from an enriched lithospheric mantle, previously metasomatized by fluids derived from subducted slab during asthenospheric upwelling, due to fragmented asymmetric delamination in a postcollisional extensional tectonic environment.

    Does structural change matter for sustainable development in newly industrialized countries? Fresh evidence from a new sustainability indicator

    Artan, Seyfettin; Erdogan, Sinan; Recepoglu, Muersit; Çakir, Suemeyra cay; Hayaloglu, Pinar; Çakir, Mehmet Ali

    The economic gap between developed and developing economies has been diminishing due to the recent rapid economic growth performance of developing economies. While achieving this swift growth level, developing economies have structurally transformed their economies. However, the impact of this structural change on environmental sustainability remains unclear. Therefore, this study focuses on the impacts of structural change, energy structure, and economic growth on the load capacity factor, a comprehensive sustainability indicator, in newly industrialized countries during 2000-2020. To this end, second-generation panel data techniques, which account for cross-sectional dependence and heterogeneity, are used to provide more robust and reliable estimates. The results show that economic growth, structural change, and fossil energy utilization decrease the load capacity factor while renewable energy utilization increases it. These findings underscore the need for energy efficiency and resource-conscious policies that align with environmental sustainability while promoting economic growth, highlighting their crucial role in the future of sustainable development.

    Role of culture and religious beliefs on non-medical help-seeking behavior among patients with chronic mental illnesses (CMIs) in Türkiye

    Ediz, Cicek; Uzun, Sevda; Mohammadnezhad, Masoud; Erdas, Mehmed B.

    Background:Cultural beliefs significantly shape societal attitudes toward mental illness, and these social attitudes profoundly impact help-seeking behaviors. Therefore, it is important to focus on understanding and addressing these social behaviors.Aim:This study aimed to evaluate the effect of chronic mental illness interpretations based on culture and religious beliefs on non-medical help-seeking behaviors among patients in T & uuml;rkiye.Methods:The study was conducted from September to October 2023 using an inductive qualitative approach. In-depth face-to-face interviews were carried out with individuals diagnosed with chronic mental illness and their relatives, registered in a state-owned Community Mental Health Center (CMHC) in T & uuml;rkiye. Using purposive sampling, 13 individuals who met the criteria were interviewed. Thematic analysis was used to identify themes.Results:Three main themes and eight sub-themes were identified, including the reasons for seeking non-medical help (psychological challenges, subjective norms, physical requirements), factors contributing to seeking non-medical help (predisposing factors, enabling factors, and myths), and reflections on the benefits of non-medical practices (perceived physical benefits, perceived psychological benefits).Conclusions:It was concluded that individuals with chronic mental illness and their relatives living in the Eastern Anatolia Region of T & uuml;rkiye engaged in non-medical help-seeking behaviors and mostly turned to traditional religious practices. Culture and religious beliefs emerged as primary factors leading patients to seek non-medical treatment approaches. Consequently, there is a perceived need to explore non-medical alternative methods across various mental health settings and with diverse samples in future research endeavors.

    Improved estimation of population variance in stratified successive sampling using calibrated weights under non-response

    Pandey, M. K.; Singh, G. N.; Zaman, Tolga; Al Mutairi, Aned; Mustafa, Manahil SidAhmed

    This paper introduces a new method to estimate the population variance of a study variable in stratified successive sampling over two occasions, while accounting for random non -response. The method uses a logarithmic type estimator and leverages information from a highly positively correlated auxiliary variable. The paper also presents calibrated weights for the new estimator and examines its properties through numerical and simulation studies. The results indicate that the suggested estimator is more effective than the standard estimator for estimating the population variance.

    Investigation of Microbiological, Physiological and Histopathological Changes in Polymicrobial I nfection in Old Rats

    Ulker, U.; Kizil, S.; Bayraktar, B.; Alçigir, M. E.; Kul, O.; Kaya, H.; Ürüsan, H.; Aydemir, S.; Kotan, G. C.; Önel, A. U.

    Background: The aim of this study is to examine the microbiological, clinical, physiological and pathological findings of natural polymicrobial infection developing in a wistar rat colony under long-term observation. Methods: In this study, 70 male Wistar albino rats, 3 years old, raised by conventional methods and housed in a cage environment were used. Thirteen rats with clinical symptoms such as torticollis and rotation were sacrificed for microbiological and histopathological examination after 14 days. For microbiological examination, the rapid diagnostic kit BBL Crystal system was used to identify bacterial agents in tissue and stool samples and the traditional culture method was used for isolation. Result: As a result of microbiological analysis, the rarely isolated Staphylococcus capitis ( S. capitis ) was isolated. Different Staphylococcus spp. It has been determined that the species can cause suppurative meningoencephalitis as well as septicemia in the brains of experimental animals., it is thought that polymicrobial infection will be useful for the identification of bacterial agents and infection prevention and treatment strategies.
