Vacancy transfer probabilities from K to L shell for low atomic number elements at 5.96 keV
(Polish Academy of Sciences, 2010)Vacancy transfer probabilities from K to L shell were measured using I K?/IK? intensity ratios for six elements in the atomic region 16 ? Z ? 22. The K X-rays from the targets excited by 5.96 keV (1.85 GBq 55Fe filtered ... -
Validation of classical quantitative fundamental parameters method using multivariate calibration procedures for trace element analysis in ED-XRF
(Royal Soc Chemistry, 2014)In this study, the X-ray intensities obtained from 76 soil samples were converted to concentrations by means of the Epsilon software program applying the fundamental parameters method (FP). Various National Institute of ... -
Variation in body size and age structure among three Turkish populations of the treefrog Hyla arborea
(Brill, 2012)To determine how climate factors influence age, body size and sexual size dimorphism (SSD) in the Mediterranean region, we generated data on age and body size of the European Treefrog, Hyla arborea, in three Turkish ... -
Variation in body size and age structure of stellagama stellio (L., 1758) (Reptilia: Agamidae) from Turkey
(Inst Zoology, Bas, 2014)Age and body size of 81 Stellagama stellio (syn. Laudakia stellio) specimens from five regions of Turkey were studied using skeletochronology. Lines of arrested growth (LAGs) in phalanges were used to estimate the age. ... -
Variation in size and shape: sexual dimorphism in the southern banded newt, Ommatotriton vittatus (Caudata: Salamandridae)
(Springer, 2023)One of the main factors creating intraspecific morphological variation, sexual dimorphism (SD) could be expressed as adult male and female animals having different body sizes or shapes. Female-biased sexual dimorphism has ... -
