Seasonal variation of trace elements and stable isotope (delta C-13 and delta N-15) values of commercial marine fish from the black sea and human health risk assessment
(Taylo & Francis Ltd., 2021)
The purpose of this study is to examine changes in stable carbon and nitrogen isotope ratios, to determine the levels of metals (aluminum, copper, iron, manganese, lead, and zinc), and to assess the health risks associated ...
Heavy metal concentrations in the edible tissues of some commercial fishes caught along the Eastern Black Sea coast of Turkey and the health risk assessment
(Taylo & Francis Ltd., 2021)
Concentrations of some metals were determined in muscle tissue of five marine fish species (Engraulis encrasicolus, Sarda sarda, Mullus barbatus, Trachurus mediterraneus, and Merlangius merlangus) caught from the Eastern ...
Characteristics and temporal trends of microplastics in the coastal area in the Southern Black Sea over the past decade
(Elsevier, 2021)
Time-series datasets showing the gradual conformational change in the status and characteristics of microplastics (MP) in marine waters are needed to protect vulnerable marine ecosystems. In this study, the abundance, ...
Formability behavior of friction stir processed dual phase steel
(EDP Sciences, 2021)
This study investigated the formability behavior of dual-phase (DP) steel subjected to friction stir process (FSP), using a miniaturized Erichsen test. The friction stir process yielded a refined microstructure, which ...
Mesoporous chromium oxide doped palladium catalysis for cyanation reaction of some aryl halides
(Elsevier, 2021)
A Pd/Cr2O3 hybrid catalyst for cyanation reaction of some aryl halides was synthesized and characterized by XRD, SEM/EDS and TEM. The porous structure of the catalyst was also investigated by BET analysis. All XRD ...
The climate change impact projections on seasonal residential sector CO2 emissions and energy demand forecasting for Turkish provinces
(Inderscience Enterprises Ltd., 2021)
The main aim of this study was to determine the seasonal Turkish climate change maps by using long-term temperature trends for the first time and add it to published literature. Residential energy demand and CO2 emissions ...
Are 9th grade students ready to engage in the theoretical discursive process in geometry?
(Hipatia Press, 2021)
This study was conducted to examine whether newly enrolled 9th grade students were ready to directly engage in the theoretical discursive process from the perspective of Duval's Cognitive Model. The sample of the study was ...
Ecological structure: production of organic impregnation material from mussel shell and combustion
(Assc Brasil Polimeros, 2022)
In the research, sea mussel shell (Chamelea gallina) powders were impregnated on the samples of Eastern spruce (Picea orientalis (L.) Link.) and Anatolian chestnut (Castanea sativa Mill.) by dipping method at different ...
Investigation and mapping of natural and artificial radioactivity in sediment samples from Borcka Black Lake, Artvin-Turkey
(Taylor & Francis Ltd., 2022)
All living creatures in nature are constantly exposed to ionising radiation, which is emitted from natural and artificial radiation sources. For this reason, it is important to monitor the levels of radioactivity in living ...
Catalytic activity of palladium doped activated carbon from waste coffee on some environmental pollutants
(Elsevier, 2022)
The presence of nitro compounds and such commercial dyes as Congo red, methylene blue, methyl orange and methyl red in water/wastewater causes environmental issues. The treatment of such industrial contaminants, new efficient ...
