The Mediterranean-Aegean region play a significant role in the context of conserving biodiversity. The protection of endemic and local species becomes attainable only with a thorough understanding of their biology. Specifically, aquatic species dwelling in inland waters may be more vulnerable due to the irregular composition of their habitats, characterized by natural barriers. It becomes imperative to initiate the conservation process by identifying the fauna and flora of ecosystems, thereby facilitating the development of comprehensive conservation plans. In this context, the primary objective of the present study is to identify freshwater fish species inhabiting Madra and Havran Streams in Balıkesir, Türkiye using the DNA barcoding method. The procedure involves DNA isolation through the Chelex protocol, followed by the amplification of the mitochondrial CO1 region using various primer combinations. The results obtained from the gene sequences of 29 individuals in total provide valuable information on species diversity, genetic relationships, and variations. This research emphasizes the importance of DNA barcoding as a valuable tool for species identification, genetic exploration, and conservation plans. The acquired outcomes establish a foundation for the effective management of aquatic biodiversity, particularly within these vulnerable ecosystems.
地中海-爱琴海地区在保护生物多样性方面发挥着重要作用。只有充分了解当地特有物种的生物学特性，才能保护这些物种。具体而言，居住在内陆水域的水生物种可能更容易受到伤害，因为它们的栖息地构成不规则，存在天然屏障。因此，必须通过确定生态系统的动植物群来启动保护进程，从而促进制定全面的保护计划。在此背景下，本研究的主要目的是利用 DNA 条形码方法识别居住在土耳其巴勒克希尔的马德拉溪和哈夫兰溪的淡水鱼类物种。该方法包括通过 Chelex 方案分离 DNA，然后使用不同的引物组合扩增线粒体 CO1 区域。从总共 29 个个体的基因序列中获得的结果为物种多样性、遗传关系和变异提供了有价值的信息。这项研究强调了 DNA 条形码作为物种鉴定、遗传探索和保护计划的重要工具的重要性。获得的成果为有效管理水生生物多样性奠定了基础，尤其是在这些脆弱的生态系统中。

The electrical and environmental disadvantages of mineral oils, traditionally used as insulating fluids in power systems, lead to the search for alternatives. Natural esters produced from vegetable seeds are one of the most important alternatives. Natural esters with high dielectric strength can meet ultra-high voltage transformer design requirements. In addition, they can respond to environmental concerns caused by transformer oils with their biodegradability. This study first compares natural esters with other trans-former oils and explains why natural esters stand out. The basic properties of natural esters are defined in terms of advantages and disadvantages, and power system applications are exemplified. Esterification and synthesis of nanoparticle-added nanofluids, widely used in the literature to improve natural esters' electrical and thermal properties, are presented with experimental applications. Natural esters can have a better oxidation stability with the esterification process. The AC, DC, and lightning impulse (LI) break-down voltages of nanofluids based on natural esters also enhanced by 10% on average. This substation and experimental applications in which natural esters are used show that these environmentally friendly oils can provide insulation requirements in many power system equipment, especially transformers.

The Biga Peninsula, which geologically evolved in relation with the the closure of the Tethyan oceans during pre-Cenozoic and subsequent syn-, post-collisional extensional tectonic regime throughout the Cenozoic located in the northwestern Türkiye. The Kirazlı district and and surrounding regional study area covers the central part of Biga Peninsula where Permo-Triassic Rhodope and Sakarya Zones sutured during closure of Paleo-Tethyan marginal seas along Intra-Pontide Suture (IPS). Neo-Tethyan northward subduction and closure, limit the Biga Peninsula from south along İzmir-Ankara-Erzincan Suture (IAES). Following syn- and post-collisional, slab break-off, slab roll-back events accompanied by crustal extension, metamorphism, core-complex formation, southward retreat of subduction front and resulted in generally southward younging magmatism. Field observations showed that Kirazlı district was exampled both Rhodope and Sakarya basement rocks along its eastern sector those were covered by Oligocene volcanic sequence at the rest of district. Resultant Cenozoic structural architecture of post-collisional tectonic regime includes three and four predominant fault orientations respectively in regional and district scale study areas. Investigating the tectonic characteristics of these faults at both regional and district scales will be instrumental in unveiling the temporal and spatial relationships among Cenozoic structures. To achieve this goal, the study examines and discusses the tectonic properties associated with the identified predominant fault orientations.

In functional Magnetic Resonance Imaging (fMRI) studies, the variability in fMRI data, the complexity of the analysis, and the need to correct for multiple comparisons make determining the appropriate sample size challenging. Hence, power analysis becomes an important tool to use for determining the appropriate sample size needed to achieve reliable and statistically significant results. In this context, this study aims to represent the process of conducting a power analysis and estimating the sample size for an fMRI study. To do this, three functional, affective, behavioral, and cognitive, data sets having different experimental task designs are used. This study provides a step-by-step guide on how to conduct a power analysis and estimate the sample size for various fMRI studies.

In recent years, studies on the design and synthesis of artificial nucleases with biological, structural and coordination properties have been increasing. With this study, mononuclear complex compounds were obtained with Cu(II), Ni(II) and Zn(II) transition metal ion salts of bis(acylhydrazone) ligand, which has the potential to show biological activity and has revolving atoms such as N and O in its structure. The characteristic structures of the obtained complex compounds were elucidated using various techniques such as FTIR, UV-Visible, 1H-NMR, TGA, elemental analysis and magnetic susceptibility. The DNA-binding activities of potential artificial metallonucleases, whose structures were elucidated, were investigated using the UV-visible absorption titration method. Additionally, their DNA-cleavge activities were analyzed using the agarose gel electrophoresis method. The DNA binding mode and cleavage mechanisms were determined as part of this study.. In line with the results obtained, it was determined that the binding mode between DNA and the complexes is a noncovalent interaction. It has been demonstrated that the compounds cleavage DNA both oxidatively and hydrolytically. It has been revealed that the radicals involved in DNA cleavage activity are H2O2, superoxide and hydroxyl radicals. It was revealed that the compound with the highest cleavage and bonding interaction was the Cu(II) complex, followed by Ni(II) and Zn(II) complexes.

In this study, the behavior of Turbulent Jet flow was investigated using Dynamic Mode Decomposition, which is a data-driven, dimension reduction method. Jet flow, which is an important and popular research topic in Fluid Dynamics and engineering applications, was considered as the fluid flow. A Large Eddy Simulation (LES) was performed using the openFOAM software to model the Jet flow. 180 snapshots were generated with the simulation to create a Jet Flow dataset of approximately 150 gigabytes. Firstly, the dynamic modes of the jet flow were extracted from this dataset to reveal the characteristic features of the flow. Then, state estimation for reconstruction of the flow were made. This significantly reduced the CPU and RAM requirement for processing data set and saved lots of disk space for storage. Performance measurements were made for the reconstructed images obtained as a result of the analyses. Two metrics were used for the measurements, namely Root Mean Square Error and Structural Similarity Index.

This study reports a revised geological map and a stratigraphic section of the Hod region. It represents a synthesis of new data and earlier work. New results gathered from field geological mapping and petrographic investigation have clarified the lithological boundaries, textural characteristics, the stratigraphical relationships between various rock formations and spatial distribution and behavior of structural elements. Hod region, located in the eastern part of the eastern Pontides (Artvin district), comprises Jurassic to Cretaceous volcanic and sedimentary sequences with a roughly north-north-east trending, steeply east dipping stratigraphy. These lithological units are Liassic Berta Formation, Dogger Kırgülü Formation and Hızarlıdere Formation, Malm-Lower Cretaceous Öğdem Formation and İnanlı Member, Lower Cretaceous Aşağımaden Formation, Turonian Çatak Formation, Santonian Kızılkaya Formation and Santonian-Campanian Evliyatepe Formation. Among these formations, intermediate to felsic volcanic and volcanosedimentary rocks of Kızılkaya Formation are significant as they host several volcanogenic massive sulfide (VMS) and epithermal deposits throughout eastern Pontides. Hod Maden Au-Cu deposit which represents one of the highest-grade gold and copper discoveries made globally in recent years is also located in Hod region. Therefore, the revised geological map and stratigraphy presented here are important contributions to the regional geology and essential tools for exploration geologists working in the region.

Fatty acids are recognized as energy sources and membrane components. The biological effects of the fatty acids are composed of influencing cell and tissue metabolism, and responding to hormonal and other signals. This study was planned to characterize the fatty acid compositions of five different mushrooms namely, Cerrena unicolor, Hymenochaete rubiginosa, Inocutis rheades, Leptoporus mollis, and Polyporus squamosus naturally distributed in Turkey by using gas chromatography (GC) and GC-mass spectrometry (GC-MS). A total of sixteen fatty acids were screened in the mushroom species. The most abundant fatty acids were recorded as linoleic (10.35-65.69%), oleic (12.03-53.27%), palmitic (12.68-21.16%), stearic (2.39-4.36%) and palmitoleic (1.40-4.26%) acids in all studied mushrooms. The amounts of unsaturated fatty acids (UFAs) (60.02-80.70%) were calculated higher than saturated fatty acids (SFAs) (19.24-39.58%). The correlations or differences of the mushroom species with regard to fatty acid compositions were chemometrically investigated by using principal component analysis (PCA) and hierarchical clustering analysis (HCA). H. rubiginosa was separated with the highest amount of linoleic acid (65.69%) from other four mushroom species in both analyses.

The risk of forest fires is a major problem in Türkiye's Mediterranean region and has a significant impact on ecosystems and atmospheric conditions. Throughout the previous century, a significant portion of Türkiye's Mediterranean Region has been destroyed by forest fires. This study aims to determine the meteorological covariates, such as relative humidity, maximum temperature, and wind speed, that affect forest fires. We classified forest fires into two groups. The first group (F1) refers to small forest fires, with burned forest areas of less than 10 hectares. The second group (F2), representing rare events, corresponds to burned areas of more than 10 hectares. The data is composed of binary values (F1=0 and F2=1) taken between the years 2015-2019 from different locations in the Mediterranean Region of Türkiye. For binary data modeling, the ordinary logistic regression (LR) has been frequently used. However, such a method tends to give biased results when using rare event data. Therefore, we employed three different modeling techniques specifically designed for rare event data. According to the results obtained from the best model, Firth's Logistic Regression (FLR), wind speed, and maximum temperature are found to be statistically significant variables in the occurrence of forest fires greater than 10 hectares.
