    Modules Whose Maximal Submodules Have Τ-Supplements
    (Luhansk Taras Shevchenko Natl Univ, 2010) Buyukasik, Engin
    Let R be a ring and tau be a preradical for the category of left R-modules. In this paper, we study on modules whose maximal submodules have tau-supplements. We give some characterizations of these modules interms their certain submodules, so called tau-localsubmodules. For some certain preradicals tau, i.e. tau=delta and idempotent tau, we prove that every maximal submodule of M has a tau-supplement if and only if every cofinite submodule of M has a tau-supplement. For a radical tau onR-Mod, we prove that, forevery R-module every submodule is a tau-supplement if and only if R/tau(R) is semisimple and tau is hereditary

    Projektiranje Nasipa Zeljezničkih Pruga Primjenom Neuronskih Mreža
    (Croatian Soc Civil Engineers-hsgi, 2013) Tayfur, Gokmen; Egeli, Isfendiyar
    The main requirement in the design of high-speed railway embankments are low values of total differential settlements. The use of cement stabilized layers in embankments, as compared to non-stabilized layers that are now most often in use, is analysed in the paper. Different cement proportions and different water/cement ratios for stabilized layers are considered. It was established that the use of cement stabilized layers in embankments can greatly reduce thickness of individual layers, while also reducing settlement. The research was conducted using the feed forward neural network.

    Preliminary Design of an Immersed Tunnel in Izmir
    (Croatian Soc Civil Engineers-hsgi, 2012) Egeli, Isfendiyar; Kartaltepe, Nisa
    Preliminary design of an immersed tunnel in Izmir Possibilities for building the Izmir Bay Immersed Tube Tunnel are analyzed in the paper. Study results show that the tunnel construction is feasible if a particular soil improvement is conducted properly. A minimum SPT-N value, compatible with concrete to be used in construction of the immersed tube, is defined so as to enable subsequent improvement of soil density. This procedure enables achievement of the minimum post-improvement soil-structure interaction stiffness level, as well as fulfilment of all other geotechnical criteria. This was demonstrated using the existing data about sub-sea soil in which the tunnel construction is planned.

    Byzantine Wall Paintings in the Archaeological Sites of Aigai, Olympos, and Anaia (Turkey): Techniques and Material Characteristics
    (Routledge Journals, Taylor & Francis Ltd, 2025) Şerifaki, K.; Böke, H.
    The aim of this study is to determine the material characteristics of the paint layers and techniques of paintings executed in Late Roman and Byzantine churches located in the archaeological sites of Aigai, Olympos, and Anaia (Turkey) in order to select compatible materials prior to conservation treatments of the paintings and to establish the technical aspects of the paintings in relation to coeval Western examples. In this context, the execution technique, microchemical characteristics, stratigraphy of paintings, and mineralogical and chemical composition of the pigments were determined by polarized light microscopy (PLM), scanning electron microscopy coupled with X-ray energy dispersive spectroscopy (SEM-EDX), and Fourier transform infrared spectroscopy (FTIR). The analysis results indicated that wall paintings were executed by fresco, secco or fresco-secco techniques on a thin plaster layer that is composed of pure lime, straw, fine marble, brick, and sand aggregates. The ground layers of the paintings are composed of kaolin, calcite, and carbon black. The color compositions of the paintings were obtained by applying successive layers of paint on the ground layers. The pigments used in the paintings are mainly iron oxides for the red and yellow, green earth in celadonite and glauconite forms for greens, and lapis lazuli and Egyptian blue for blues. The present study demonstrates that the techniques and materials employed in the execution of wall paintings in Byzantine churches in Western Anatolia are analogous to those utilized in the Balkans, Crete, and Cyprus, with the exception of the presence of a clay-based ground. © The International Institute for Conservation of Historic and Artistic Works 2025.

    Microporous Carbon Spheres for the Enrichment of Lead From Water Samples With Determination by Microsample Injection System - Flame Atomic Absorption Spectrometry (MIS-FAAS)
    (Taylor & Francis inc, 2025) Njjar, Muath; Ugan, Muhammet; Akturk, Ezgi Zekiye; Pelech, Iwona; Staciwa, Piotr; Akdogan, Abdullah
    Microporous carbon spheres (MCSs) are advanced materials known for their high surface area, well-developed pore structure, low density, and rapid molecular diffusion, making them highly effective in solid-phase extraction (SPE) and other applications. In this study, MCSs synthesized from previously reported resorcinol-formaldehyde resin were employed as an adsorbent for the extraction and preconcentration of Pb(II) ions. The material was comprehensively characterized to confirm its suitability for adsorption applications. The adsorption and desorption behavior of MCSs toward lead ions was systematically examined under optimized conditions, including pH, eluent volume, eluent type, eluent concentration, and sample volume. Microinjection microsample injection system-flame atomic absorption spectrometry (MIS-FAAS) was used for the determination of lead ions. Experimental results from batch experiments showed that the MCSs exhibited a maximum adsorption capacity of 37.31 mg g-1. Under optimal conditions (pH 8.0, 1.0 mL of 0.1 M HNO3 eluent, and 10 mg of adsorbent), a preconcentration factor of 100 was achieved, with recovery values exceeding 90%. The method exhibited a limit of detection (LOD) of 0.73 mu g L-1. The developed method was successfully applied to real water samples, including tap water, entering industrial wastewater, and exiting industrial wastewater, confirming its potential for use in environmental monitoring and contamination control.

    Review of the Relationship Between Growth Hormone and SARS-CoV-2 Infection
    (Taylor & Francis Ltd, 2025) Rasmi, Yousef; Kirboga, Kevser Kubra; Roshanravan, Neda; Tekin, Burcu; Jalali, Ladan; Ghazizadeh, Farid
    Recent evidence suggests that SARS-CoV-2 is associated with the endocrine system, particularly growth hormone (GH). GH modifies immune responses and its deficiency could be responsible for the uncontrolled immunity that occurs in severe cases of COVID-19. Recent research shows that patients suffering from lung complications have significantly lower levels of GH and insulin-like growth factor-1 (IGF-1), which are proportionate to the severity of the disease. This relationship supports the hypothesis that GH regulates the immunity and inflammatory processes of the SARS-CoV-2 virus. However, variables such as age, gender, and comorbidities, such as diabetes and obesity, which are associated with lower GH levels, are strong predictors of COVID-19 outcomes. Older individuals and men, who tend to have lower GH levels, are disproportionately represented among severely ill patients. The available evidence suggests that GH supplementation therapy should be evaluated as a supportive measure to reduce the severity of the disease in high-risk individuals. The main goal of the research is to understand how COVID-19 is related to GH so that researchers can identify new mechanisms of pathology and develop better solutions for patients.

    Poly(Ethylene Glycol)-Keratin Hydrogels Prepared Via Thiol-Maleimide Reaction
    (Polymer Soc Korea, 2025) Yalcin, Damla; Top, Ayben
    The mechanical properties of hydrogels have a profound effect on cellular responses in tissue engineering applications. In this study, poly(ethylene glycol)-keratin (PEG-KRTN) hydrogels with tunable mechanical properties were prepared by varying molar mass of the maleimide functionalized PEG in the thiol-maleimide chemistry. Reduced keratins were reacted with PEG-maleimides having 2000 Da and 6000 Da molar masses. Viscoelastic and physiochemical properties and cytocompatibility of these hydrogels were tested. Storage modulus values were obtained as 2613 +/- 254 Pa and 1313 +/- 345 Pa for PEG2000-KRTN and PEG6000-KRTN hydrogels, respectively. Strain sweep data indicate that the linear viscoelastic region (LVER) of the PEG6000-KRTN hydrogel spans up to 40% strain value, whereas it is limited to 10% critical strain for the PEG2000-KRTN hydrogel. PEG6000-KRTN hydrogel presented higher swelling ratios and porosity. CCK-8 test showed that both hydrogels promoted the proliferation of L929 mouse fibroblast cells and, hence, can be applied in soft tissue engineering.
