On Generalized Constant Ratio Surfaces of Higher Codimension
(Springer Basel Ag, 2019)
In this paper, we introduce constant slope (CS) and generalized constant ratio (GCR) submanifolds with higher codimension in Euclidean spaces. We firstly obtain a classification of GCR surfaces in Euclidean 4-spaces E4. ...
New results on helix surfaces in the Minkowski 3-space
(Int Electronic Journal Geometry, 2019)
In this paper, we characterize and classify helix surfaces with principal direction relatived to a space-like and light-like, constant direction in the Minkowski 3-space.
On surfaces endowed with a canonical principal direction in Euclidean 4-spaces
(Scientific Technical Research Council Turkey-Tubitak, 2019)
In this paper, we introduce canonical principal direction (CPD) submanifolds with higher codimension in Euclidean spaces. Then we obtain a classification of surfaces endowed with CPD relative to a fixed direction in Euclidean ...
Polynomial Affine Translation Surfaces in Euclidean 3-Space
(Soc Paranaense Matematica, 2019)
In this paper we study the polynomial affine translation surfaces in E-3 with constant curvature. We derive some non-existence results for such surfaces. Several examples are also given by figures.
Soil Erosion Risk Assessment due to Land Use/Land Cover Changes (LULCC) in Bulgaria From 1990 to 2015
(Kastamonu Univ, 2019)
Soil erosion by water jeopardizes land use/cover changes (LULCC) for anthropogenic reasons. It results in enormous and irreversible damage if no action is taken. The Balkan Peninsula has experienced considerable LULCC in ...
An Approach to Life Science and Social Sciences Curriculum in Terms of Cultural Geography
(T.C. Milli Egitim Bakanligi, 2019)
Cultural geography is located in the junction point of culture and geography. Along with this, since the cultural geography has a wide scope and content, it has allowed a wide variety of definitions. Cultural geography is ...
The Saricicek howardite fall in Turkey: Source crater of HED meteorites on Vesta and impact risk of Vestoids
(Wiley, 2019)
The Saricicek howardite meteorite shower consisting of 343 documented stones occurred on September 2, 2015 in Turkey and is the first documented howardite fall. Cosmogenic isotopes show that Saricicek experienced a complex ...
Conformal cosmological black holes: Towards restoring determinism to Einstein theory
(Springer Heidelberg, 2019)
A widespread solution-generating technique of general relativity consists of conformally transforming known seed solutions. It is shown that these new solutions always solve the field equations of a pathological Brans-Dicke ...
Characterization of one-step deposited Cu2ZnSnS4 thin films derived from a single crystalline powder
(Pergamon-Elsevier Science Ltd, 2019)
In this paper, Cu-deficient and Zn-rich Cu2ZnSnS4 (CZTS) single crystals were successfully grown by Bridgman technique. Following the investigation of structural and photo-electrical properties of the grown CZTS crystal, ...
Structural, spectral and optical properties of rocksalt Al,Mn-doped CdO: experimental and DFT studies
(Springer, 2019)
Nano-crystalline Cd0.95-xMn0.05AlxO (x = 0, 0.02, 0.04, 0.06, 0.08, 0.10) semiconductors were synthesized by sol-gel technique. These samples are characterized via X-ray diffraction (XRD), scanning electron microscope (SEM) ...
