Helicoidal surface of logaritmic spiral type in 3-space
(International Conference on Computational Mathematics and Engineering Sciences, 2019)In this paper, we study the logaritmic spiral-type helicoidal surface in Euclidean 3-space. We obtain logaritmic spiral-type helicoidal surface with some figures, and calculate its curvatures. -
Astrohelicoidal hypersurfaces in 4-space
(International Conference on Mathematics and Mathematics Education, 2019)We consider an astrohelicoidal hypersurface which its profile curve has astroid curve in the four dimensional Euclidean space E4. We also calculate Gaussian curvature and the mean curvature, and Weingarten relation of the ... -
One sided Henry Smith surface
(International Conference on Computational Mathematics and Engineering Sciences, 2019)We focus differential geometry of the Henry Smith surface in the three dimensional Euclidean space. We calculate the Gaussian and the mean curvatures of the surface, drawing its figure. In addition, we find algebraic ... -
Astrohelicoidal surfaces
(International Conference on Mathematics and Mathematics Education, 2019)We construct an astrohelicoidal surface which its profile curve has astroid curve in the three dimensional Euclidean space E3.

The effect of kombucha fermentation on chestnut cancer factor (cryphonectria parasitica (murrill) e.m barr)
(Kastamonu Üniversitesi, 2018-09)Aim of study: Kombucha is a drink obtained by fermentation of sugary tea composed of acetic bacteria and yeast symbiosis. Its effect on prostate cancer and apoptosis, antimicrobial and antioxidant effect in culture medium ... -
Alleviation of copper stress with homobrassinosteroid in germinating sunflower roots
(Fresenius Environmental Bulletin, 2016-11)We investigated potential alleviation effects of homobrassinosteroid (HBR) hormone on sunflower (Helianthus annuus L. cv. TR003) grown under copper (Cu) stress conditions. Seeds were grown under Cu (30 µM and 40 µM) ... -
Effects of different concentrations of bap and naa on micropropagation of crambe orientalis l. var. orientalis l.
(The Journal of Animal & Plant Sciences, 2017-09)Crambe L. is a species of the Brassicaceae family. It is an important industrial oil plant with high erusic acid content. The objective of this study was to develop an efficient micropropagation protocol for Crambe ... -
