Evaluating the expectations of residents regarding the positive impacts of tourism
(University Externado Colombia, 2022)
The aim of this study is to determine and evaluate the expectations of residents regarding the impacts of tourism. The expectations of the residents are handled through the Kano Model and the Analytic Hierarchy Process. ...
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 ...
Comparison of heavy metal levels and health risk assessment of different bread types marketed in Turkey
(Elsevier, 2022)
In this study, the manganese (Mn), aluminum (Al), copper (Cu), nickel (Ni), chromium (Cr), lead (Pb), arsenic (As), cadmium (Cd), cobalt (Co), and mercury (Hg) levels of 60 bread samples were determined by ICP MS, all of ...
The broad-scale microplastic distribution in surface water and sediments along Northeastern Mediterranean shoreline
(Elsevier, 2022)
Plastics manufactured to fulfil the unique demands of civilization accumulate in the sea due to their durability. Microplastics (MP) pose a greater threat than macroplastics as they can easily enter the aquatic environment ...
Plastic occurrence in commercial fish species of the Black Sea
(Central Fisheries Research, 2022)
The occurrence of micro- ( 5 mm), meso- (5-25 mm) and macroplastics ( 25mm) was investigated in seven commercial fish species of the Black Sea. Plastics were found in gastrointestinal track of all species analysed: Engraulis ...
Occurrence of microplastics in herpetological museum collection: Grass snake (Natrix natrix [Linnaeus, 1758]) and dice anake (Natrix tessellata [Laurenti, 1769]) as model organisms
(Springer, 2022)
Microplastics are plastic fragments with a size less than 5 mm in length. In addition to a threat to the marine environments where these are abundantly present, these have also started polluting freshwater ecosystems. ...
Radiometric mapping and radiation dose assessments in sediments from Savsat Black Lake, Turkey
(Springer, 2022)
In this study, natural and artificial radioactivity concentrations in sediment samples taken from Savsat Black Lake located on the Nature Park in Artvin were determined using a high purity germanium detector. It was ...
