Ruled surfaces in E 3 with density
(The Honam Mathematical Society (HMSK), 2019)In the present paper, we study curves in E-3 with density e(,)(ax2 + by2) where a, b is an element of R not all zero constants and give the parametric expressions of the curves with vanishing weighted curvature. Also, we ... -
Embankment Surfaces in Euclidean 3-Space and Their Visualizations
(Communications in Mathematics and Applications, 2019)In the present paper, we obtain the parametric representation of an embankment surface and give an example for it. We define the notions of embankmentlike surfaces and tubembankmentlike surfaces. Furthermore, we create ... -
Sediment contamination by trace elements and the associated ecological and health risk assessment: A case study from a large reservoir (Turkey)
(Elsevier, 2022)Although Keban Reservoir (KR) is Turkey's the second largest man-made reservoir, limited data are available on the contents of trace elements (TEs) in sediments of the KR. The concentrations of 23 less- and commonly-monitored ... -
Rotational hypersurfaces in Lorentz-Minkowski 4-space
(Hacettepe Üniversitesi, 2021)In this study, we study rotational hypersurfaces in 4-dimensional Lorentz-Minkowski space. We find the rotational hypersurfaces about spacelike axis according to Gaussian and mean curvatures in E-1(4) and give some results ... -
Environmental, ecological and health risks of trace elements, and their sources in soils of Harran Plain, Turkey
(Elsevier, 2020)Soil pollution with trace elements (TEs) has become an increasingly serious environmental concern, however, assessment of ecological and human health risks especially in intensive agricultural regions remains limited. In ... -
A comparison of trace element concentrations in surface and deep water of the Keban Dam Lake (Turkey) and associated health risk assessment
(Elsevier, 2020)Keban Dam Lake (KDL) is the second largest dam lake in Turkey. There have been some reports on the trace element (TE) levels in surface water of the KDL, but its deep water has been never studied. We measured 17 TEs (Pb, ... -
Environmental, ecological and health risks of trace metals in sediments of a large reservoir on the Euphrates River (Turkey)
(Elsevier, 2020)The contents of trace metals (Cd, As, Pb, Cr, Cu, Zn, Ni, Co, Mn and Fe) in sediment samples from eleven sampling sites in The Keban Dam Reservoir, which is Turkey's second biggest reservoir, were examined to evaluate ... -

(Elsevier, 2020)Two fish species (Capoeta umbla and Luciobarbus mystaceus) were collected from the Tigris River (Turkey), and tissues (gill, muscle and liver) of fish samples were analyzed for Cd, As, Mn, Cr, Cu, Co and Ni using the ... -
Characteristics of effluents from trout farms and their impact on water quality and benthic algal assemblages of the receiving stream
(Elsevier, 2020)In this study, characteristics of effluents from three flow-through rainbow trout farms in Turkey and their impact on water quality and epilithic algal communities of the receiving stream were investigated. Water samples ... -
