The presence of microplastics in Baran’s newt (Neurergus barani Öz, 1994) and the spotted newt (Neurergus strauchii Steindachner, 1887)
(Springer, 2024)Microplastics (MPs), tiny plastic particles less than 5 mm in size, have emerged as a common and worrying pollutant in marine, freshwater, and terrestrial environments worldwide. In this study, we revealed the microplastic ... -
Extension of TODIM method based on distance measures of decomposed fuzzy sets
(Springer, 2024)Fuzzy sets allow elements to have partial membership in a set, represented by a membership value between 0 and 1. This feature enables fuzzy sets to model imprecise or vague concepts. Decomposed fuzzy sets, an extension ... -
Fine-tuning the element dose in nanoparticle synthesis is the critical factor determining nanoparticle's impact on plant growth
(Elsevier, 2024)This study elucidates the impact of element dose during nanoparticle (NPs) synthesis on plant growth indices. Novel NPs containing two essential micro-nutrients, zinc (Zn) and manganese (Mn), were co-doped on cerium oxide ... -
Utilizing fractional derivatives and sensitivity analysis in a random framework: a model-based approach to the investigation of random dynamics of malware spread
