Antioxidant and acetylcholinesterase inhibition properties of novel bromophenol derivatives
(Elsevier, 2015-06)In this study, series of novel bromophenol derivatives were synthesized and investigated for their antioxidant and AChE inhibition properties. Novel brominated diarylmethanones were obtained from the acylation reactions ... -
The effects of some bromophenols on human carbonic anhydrase isoenzymes
(Informa, 2016)Carbonic anhydrases (CAs, EC 4.2.1.1), which are involved in a variety of physiological and pathological processes, are ubiquitous metalloenzymes mainly catalyzing the reversible hydration of carbon dioxide (CO2) to ... -
Synthesis of 4-(2-substituted hydrazinyl)benzenesulfonamides and their carbonic anhydrase inhibitory effects
(Informa, 2016)In this study, 4-(2-substituted hydrazinyl)benzenesulfonamides were synthesized by microwave irradiation and their chemical structures were confirmed by H-1 NMR, (CNMR)-C-13, and HRMS. Ketones used were: Acetophenone (S1), ... -
On I_{σ}-convergence of folner sequence on amenable semigroups
(New Trends in Mathematical Sciences, 2018-04)In this paper, the concepts of-uniform density of subsetsAof the setof positive integers and corresponding-convergence of functions defined on discrete countable amenable semigroups were introduced. Furthermore, for any ... -
Synthesis and bioactivity studies on new 4-(3-(4-Substitutedphenyl)-3a,4-dihydro-3H-indeno[1,2-c]pyrazol-2-yl) benzenesulfonamides
(Informa, 2016)A series of new 4-(3-(4-substitutedphenyl)-3a, 4-dihydro-3H-indeno[1,2-c] pyrazol-2-yl) benzenesulfonamides (7-12) was synthesized starting from 2-(4-substitutedbenzylidene)-2,3-dihydro-1H-inden-1-one (1-6) and ... -

On generalized euler spirals in E3
(2016)The Cornu spirals on plane are the curves whose curvatures are linear. Generalized planar cornu spirals and Euler spirals in E3, the curves whose curvatures are linear are deÖned in [1,5]. In this study, these curves are ... -
TF-type hypersurfaces in 4-Space
(Mersin Üniversitesi, 2016)We study on translation and factorable hypersurfaces in the four dimensional Euclidean space. We calculate implicit algebraic equations of the hypersurfaces. -
Bour's surface in the 3-dimensional Minkowski space

Some characterizations of euler spirals In E3_1
(2016)In this study, some characterizations of Euler spirals in E3_1 have been presented by using their main property that their curvatures are linear. Moreover, discussing some properties of Bertrand curves and helices, the ... -
Weierstrass representation degree and classes of the surfaces in the four dimensional Euclidean space
(Celal Bayar University, 2017)We study two parameters families of Bour-type and Enneper-type minimal surfaces using the Weierstrass representation in the four dimensional Euclidean space. We obtain implicit algebraic equations, degree and classes of ... -
Bour s theorem on timelike helicoidal surfaces with L L type in Minkowski 3 space
(Beykent University, 2008) -
Bour s theorem on gauss map in 3 euclidean space
(Hacettepe Üniversitesi, 2010)In this paper some relations are established between the Laplace-Beltrami operator and the curvatures of helicoidal surfaces in 3-Euclidean space. In addition, Bour’s theorem on the Gauss map, andsome special examples are given. -
III laplace beltrami and (S,L)-type rotational surface
(Longdom Publishing SL, 2012)We study on the third Laplace-Beltrami operator of timelike rotational surface of (S,L)-type in three dimensional Minkowski space. -
Uniform I-lacunary statistical convergence on time scales

The λ ̅-statistically convergent double sequences in fuzzy normed spaces
(Elsevier, 2019-03)We introduce double λ -statistically convergent sequences and double λ -statistically Cauchy sequences in the fuzzy normed spaces. We study [V,λ ] and [C,1]-summabilities for double sequences. In addition, we obtain the ...
