An extension of asymptotically lacunary statistical equivalence set sequences
(2013)This paper presents, for sequences of sets, the notions of asymptotically lacunary statistical equivalent (Wijsman sense) of multiple L, strongly asymptotically lacunary p-equivalent (Wijsman sense) of multiple L and ... -
Correlation between soil gas radon concentrations and terrestrial radioactivity (U-238 and Th-232) in Afyonkarahisar
(Alanya Alaaddin Keykubat Üniversitesi, 02.2019)Humans are exposed both to natural radiation from the radioactive elements that have existed in the earth's crust since the formation of the earth and to artificial radiation from medical applications and sparrows after ... -
Comparison of radon concentrations in soil gas and indoor environment of Afyonkarahisar province
(16 April 2)It is well known that radon is the main source of natural radiation exposure to the population. Indoor radon concentrations in an area are affected by ascending radon migration following the convection of groundwater and ... -
Asymptotically ideal invariant equivalence
(2018)In this paper, the concepts of asymptotically I_σ-equivalence, σ-asymptotically equivalence, strongly σ-asymptotically equivalence and strongly σ-asymptotically p-equivalence for real number sequences are defined. Also, we ... -
A generalization of I-asymptotically lacunary statistical equivalence of sequences of sets
(2014)This paper presents, for sequences of sets, a generalization of the concept of I-asymptotically lacunary statistical equivalence by using the sequence p=(p_k) which is the sequence of positive real numbers where I is an ... -
Proteomic analysis of flowers at two developmental stages in Thermopsis turcica (Fabaceae)
(2017)Flower development is a complex physiological phenomenon that is affected by environmental stimuli and endogenous signals. Several molecular approaches have provided a comprehensive view of the physiological processes ... -
Hydroxyapatite (HAP) coating with biomimetic method abstract
