Microplastic emission trends in Turkish primary and secondary municipal wastewater treatment plant effluents discharged into the Sea of Marmara and Black Sea
(Elsevier, 2023)Wastewater Treatment Plants (WWTPs) are recognized as one of the primary sources of microplastics, a class of contaminants that has lately gained attention. The quantity of MP that WWTPs release into the environment depends ... -
Protracted dynamicity of microplastics in the coastal sediment of the Southeast Black Sea
(Pergamon-Elsevier Science Ltd., 2023)This study provided the first evaluation of microplastic abundance, features, risk assessment, and decade - changing status in sediment along the southeastern Black Sea coast. Sediment samples were collected from thirteen ... -
Enhancing transient response performance of automatic voltage regulator system by using a novel control design strategy
(Springer, 2023)The terminal voltage of the synchronous generator must be kept between determined values by a closed-loop control system called automatic voltage regulator (AVR). To enhance the performance of the AVR system, this study ... -
Improvements in the phylogeny of Epilobium and Chamaenerion inferred from nrDNA and cpDNA data focusing on Türkiye
(Scientific Technical Research Council Turkey, TÜBİTAK, 2023)Epilobium and Chamaenerion included 165 and 8 species over the world, respectively. The members of the genera are distributed particularly in moist habitats from subpolar to tropical regions. This paper aims to provide ... -
Distribution and sources of particulate organic matter from the anthropogenically disturbed Iyidere River to the Black Sea coast
(Frontiers Media, 2023)Understanding the biogeochemical processes of particulate organic matter occurring in the river under anthropogenic disturbances and its transport to the coastal system is important for environmental resource management. ... -
Plastic occurrence in fish caught in the highly industrialized Gulf of Izmit (Eastern Sea of Marmara, Turkiye)
(Elsevier, 2023)Occurrence of micro-(<5 mm) and mesoplastics (5-25 mm) in twelve fish species caught off Gulf of Izmit in the Sea of Marmara was investigated. Plastics were found in the gastrointestinal tracks of all the analysed species: ... -
Automatic generation controller based on whale optimization algorithm in PV-thermal power systems
(Gazi Üniversitesi, 2023)To ensure a balance between the power generated and the consumed power in power systems, a control process namely automatic generation control (AGC) must be carried out. This process becomes more challenging due to increasing ... -
Selectivity of monofilament gillnets with different mesh sizes used in fishing of pearl mullet, (Alburnus tarichi (Guldenstadt, 1814)) in Lake Van
(Ege University, 2023)This study was carried out between September 2020 and March 2021 to determine the selectivity of monofilament gillnets used in pearl mullet, Alburnus tarichi (Güldenstädt, 1814), fishing in Lake Van. The SELECT method was ... -
A new water-soluble zinc azaphthalocyanine containing azo groups: synthesis, characterization, fastness and antibacterial properties on cotton fabric
(E.U. Printing and Publishing House, 2023)A novel water-soluble zinc azaphthalocyanine containing azo groups (Azo-ZnAzaPc) was synthesized and characterized using FT-IR, H-1 NMR, C-13 NMR, UV-vis, MS and elemental analysis. A dyeing experiment was performed on ... -
Agomelatine attenuates cisplatin-induced cognitive impairment via modulation of BDNF/TrkB signaling in rat hippocampus
(Elsevier, 2023)Cisplatin is a drug used effectively in the treatment of malignant tumors. However, cisplatin has many side ef-fects, including cognitive impairment. Agomelatine, a synthetic melatonin analogue, is an important antide-pressant. ... -
Distribution and molecular characterisation of species of the Malacostraca (Crustacea) in the Eastern Black Sea brackish waters
