(Dinbilimleri Akad Arastirma Merkezi, 2019)In this research, a psychological analysis was made on Birgili Mehmed Efendi's personality in terms of the dimensions of extraversion and introversion of personality by using the archive search method. The aim of the ... -
Approximation by norlund and riesz means in weighted lebesgue space with variable exponent
(Ankara Univ, 2019)We investigate the approximation properties of Norlund and Riesz means of trigonometric Fourier series are investigated in the subset of weighted Lebesgue space with variable exponent. -
TGF-beta downregulates CAIII expression via MAPK and PI3K signaling pathways in colon carcinoma and osteosarcoma cells
(Inst Bioloska Istrazivanja Sinisa Stankovic, 2019)Identification of cancer-associated genes is critical for developing effective treatments of colorectal cancer (CRC). A limited number of studies have examined the mechanisms and genes underlying CRC. Abnormal transforming ... -
Maximal convergence of faber series in smirnov-orlicz classes
(Univ Prishtines, 2019)It is known that Faber series are used for solving many problems in mechanical science, such as the problems on the stress analysis in the piezoelectric plane and the problems on the analysis of electro-elastic fields and ... -
God representation and its psychological reflections in rollo may
(Hitit Univ, 2019)The aim of this study is to reveal Rollo May's views from his God Representation by means of findings obtained by archival scanning method. According to Rollo May, the basic motivation of man is to resemble the God he ... -
Fixed-disc results via simulation functions
(Scientific Technical Research Council Turkey-Tubitak, 2019)In this paper, our aim is to obtain new fixed-disc results on metric spaces. To do this, we present a new approach using the set of simulation functions and some known fixed-point techniques. We do not need to have some ... -
Minimal free resolutions of the tangent cones for Gorenstein monomial curves
(Scientific Technical Research Council Turkey-Tubitak, 2019)We study the minimal free resolution of the tangent cone of Gorenstein monomial curves in affine 4-space. We give the explicit minimal free resolution of the tangent cone of noncomplete intersection Gorenstein monomial ... -
Synthesis, characterization and environmental application of activated carbon from black seed meal biomass
(Parlar Scientific Publications (P S P), 2019)This study dealts with preparation of the activated carbon from black seed meal biomass as an adsorbent for the adsorption of methylene blue (MB) from aqueous solution. The produced activated carbon was characterized by ... -
On C-parallel legendre curves in non-sasakian contact metric manifolds
(Univ NIS, 2019)In (2n + 1)-dimensional non-Sasakian contact metric manifolds, we consider Legendre curves whose mean curvature vector fields are C-parallel or C-proper in the tangent or normal bundles. We obtain the curvature characterizations ... -
(1-x)BaFe12O19/ xCoFe(2)O(4) hard/soft magnetic nanocomposites: Synthesis, physical characterization, and antibacterial activities study
(Elsevier Science BV, 2019)In the current study, nanocomposites of (1-x)BaFe12O19/xCoFe(2)O(4) (x = 0.3, 0.5, and 0.7) were prepared via sal-gel method. Their structural and magnetic properties were chracterized using X-ray diffractometer (XRD), ... -
