    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.

    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.

    (Univ Zagreb Fac Mechanical Engineering & Naval Architecture, 2025) Coskun, Ali; Etyemez, Ayhan; Ay, Mustafa; Kurt, Mustafa; Katmer, Sukran; Seker, Ulvi; Nohuz, Mine
    This study investigate the stack drillability of unidirectional (UD) carbon fibre reinforced thermoplastic matrix PAEK/CF composite and AA7075 plate utilised in aerospace. The effects of the cutting parameters on cutting forces during the drilling process of thermoplastic matrix composites and aluminium materials were experimentally analysed. Drilling operations were carried out on a CNC Vertical Machining Centre under dry-cutting conditions. For three different drill types, three different cutting speeds, and feed rate combinations, a total of 810 holes were drilled in a full factorial experimental design with 30 replicates for each combination. The damage on the hole surfaces on the drilled composite was identified with an optical microscope. The numerical data were obtained in the composite testing laboratory and analysed using Minitab (R) 21.1 statistical software and transformed into graphs. The most suitable drill type and cutting parameters were determined for the drillability of composite with thermoplastic matrix and aluminium (AA7075) plates when stacked.

    Comparative Analysis of Ahp and Swara Methods for Prioritizing Conservation Projects Supported by Heritage Funds: a Case Study From Turkey
    (Inst Advanced Science Extension, 2025) Avsar, Oncu Basoglan; Ekinci, Kerem; Soker, Ali Ikram
    Effective budget allocation and financial management are vital for preserving cultural heritage, particularly in countries with limited resources. This study focuses on Turkey's Contribution to the Conservation of Built Heritage (CCBH) fund, which supports heritage preservation through government funding. Despite the fund's importance, a structured method for prioritizing project applications is lacking. This research proposes a decision-making framework for assessing and ranking conservation funding requests using Multiple-Criteria Decision-Making (MCDM) methods. The study applies and compares the Analytic Hierarchy Process (AHP) and the Step-Wise Weight Assessment Ratio Analysis (SWARA) to assign weights to assessment criteria. The findings demonstrate that SWARA provides a more efficient and practical approach to prioritizing conservation projects. The proposed framework aims to assist decision-makers and conservation practitioners in optimizing the allocation of funds to safeguard cultural heritage effectively. (c) 2025 The Authors.

    Cx32 Cellular Localization Is Related To Epithelial To Mesenchymal Transition in Breast Cells
    (Pleiades Publishing inc, 2025) Oz, Sercan; Turan, Fatma Basak; Yondem, Eyup; Pesen-Okvur, Devrim; Yalcin-Ozuysal, Ozden; Ozcivici, Engin; Mese, Gulistan
    Connexins (Cx) play both gap junction-related and -independent roles in cells, and their localization is essential for their function in cellular processes. Besides membrane localization, connexins can also be localized to the cytoplasm and nucleus, especially in cancer cells. The differential localization of connexins including Cx32 was observed in different stages of cancers. Cx32 was upregulated and observed in cytoplasms of cells in lymph-node metastasis of breast cancer samples compared to primary tumors. However, the significance of the increase in Cx32 expression and alteration of Cx32 cellular localization in epithelial-to-mesenchymal transition (EMT) is not known. To determine if Cx32 overexpression and/or localization over one week would induce the EMT process, we first examined the cellular localization of Cx32 in MCF10A and MDA-MB-231 cells at different time points using Western blot and RT-PCR as well as immunostaining with confocal microscopy. Then, we correlated the changes of Cx32 expression and localization with EMT marker expression. We showed that Cx32 had altered cellular localization and Cx32 overexpression increased Slug levels while it reduced E-cadherin and Snail expression in MDA-MB-231 for 7 days. In contrast, E-cadherin and Vimentin were reduced in MCF10A-Cx32 cells compared with controls over 7 days, and the expression pattern for nuclear Cx32 and Zeb2 was following similar pattern in MCF10A cells. Our results suggest a previously unknown time-dependent relation between Cx32 and the regulation of the EMT process.

    Legal Aspects for the Conservation of Rural Built Heritage: a Systematic Literature Review
    (Emerald Group Publishing Ltd, 2025) Ilbey, Zeynep Ozkaya; Yuceer, Hulya
    Purpose - This study aims to provide a base for the policy-making process of rural built heritage conservation by systematically analysing existing legal aspects and policies in the literature. The primary objective is to help the policy-making process in countries that lack specific guidelines for the conservation of rural built heritage. It is also intended to play a role in the development of existing policies. Design/methodology/approach - The paper undertakes a comprehensive and systematic review of literature through 81 publications pertaining to the legal dimensions of RBH conservation. It processes the data obtained and presents it as bibliometric information utilizing VOS-viewer and Bibliometrix. The literature review results and data are associated with international regulations and documents. As a result, principles that will be helpful to the policy-making process are produced. Findings - The study reveals that interest in the subject has increased since 2018, mainly due to the influence of international charters, documents and developments in the field. The literature review shows that existing laws address the issue broadly rather than focusing directly on RBH. However, current policies, management plans and recommendations referred to in the literature are more closely related to RBH. Nonetheless, notable provisions in laws, international documents and local policies contribute to generating policy principles on the subject. Originality/value - The study fills a gap in the literature by examining RBH conservation from a legal perspective, systematically presenting the relevant literature to researchers, policymakers and other stakeholders in various contexts.

    Systematic Review of Emerging Trends in Soil-Based Probiotic
    (Malaysian Soc Soil Science, 2024) Khairul, S. R.; Leong, S. S.; Korel, F.; Lingoh, A. D.; Toh, Seng Chiew
    Soil-based probiotics (SBPs) are microorganisms originating from soil that have the potential to significantly enhance soil fertility and plant health, similar to the benefits of conventional probiotics in human and animal health. While much is known about the role of SBPs in the animal's gut, the specific mechanisms and long-term impacts of SBPs in soil ecosystems remain underexplored. This review systematically summarizes recent research on SBPs, with a focus on lactic acid bacteria (LAB), including Lactobacillus and Bifidobacterium, and their role in soil and plant ecosystems. A comprehensive literature search was conducted using major databases, including PubMed, Web of Science, Scopus, and Google Scholar, covering the past 20 years. Out of 90 initial studies, 30 were excluded for irrelevance, and a further 60 were omitted based on selection criteria, leaving only the most relevant studies for analysis. The review highlights the multifaceted applications of SBPs in agriculture, focusing on their ability to enrich soil microbiomes, promote plant growth, and suppress pathogens. Additionally, SBPs offer sustainable alternatives in livestock feed. A comparison between SBPs and traditional probiotics underscores the unique advantages of soil-derived strains in agricultural systems. As sustainable agriculture practices grow in importance, SBPs present a natural, eco-friendly approach to improving soil health and plant resilience. Continued research is vital to fully harness the potential of SBPs, contributing to long-term soil health, sustainable farming, and global food security.

    Simulation of Geothermal Energy Production Utilizing Abandoned Oil and Gas Wells
    (State Oil Co Azerbaijan Republic, Oil Gas Scientific Research Project inst, 2024) Mukhtarov, A. N.; Akkurt, G. E.; Yildirim, N. H.
    Abandoned oil and gas wells (AOGWs) with suitable reservoir temperatures present a promising opportunity to convert subsurface heat into thermal energy or electricity for various applications. This study developed a rigorous thermodynamic model for a single-flash geothermal power plant utilizing a double-pipe direct heat exchanger (DHE), leveraging data from existing literature and modeling via Engineering Equation Solver (EES) software. The model simulates the system using R134a as the working fluid, assessing the influence of rock properties, geothermal gradient, DHE geometry, insulation thickness, mass flow rate of the working fluid, and alternative working fluids on heat extraction efficiency. This innovative approach allows for the efficient utilization of available geothermal heat resources, thereby enhancing the potential for sustainable energy generation. Key findings reveal that the power generation potential from AOGWs employing DHEs is significantly affected by the geothermal gradient within the well, the length of the heat exchanger, and the thermal conductivity of the surrounding rock. Additionally, the model projects the system's long-term performance over a 20-year period, emphasizing the importance of variable fluid characteristics inside the exchanger. Overall, the simulations underscore the necessity of carefully considering these factors to optimize energy extraction from AOGWs. The results highlight the feasibility of harnessing geothermal energy in low-flow-rate conditions, ultimately contributing to the sustainability of energy resources and offering insights for future developments in geothermal energy systems. This approach not only addresses environmental concerns associated with AOGWs but also positions them as viable assets for renewable energy generation.
