A novel synthesis of 3,6-bis(2,3-dihydrothieno[3,4-b][1,4]dioxin-5-yl)-9-tosyl-9H-carbazole
(Ovidius Univ Press, 2012)
3,6-bis(2,3-dihydrothieno [3,4-b][1,4]dioxin-5-yl)-9-tosyl-9H-carbazole (EDOTTsCz) was synthesized and electrochemically polymerized on glassy carbon electrode (GCE) in 0.1 M tetrabutyl ammonium tetrafluoroborate ...
Cotangent bundle reduction and Poincare-Birkhoff normal forms
(Elsevier, 2014)
In this paper we study a systematic and natural construction of canonical coordinates for the reduced space of a cotangent bundle with a free Lie group action. The canonical coordinates enable us to compute Poincare-Birkhoff ...
A Short Survey on Surfaces Endowed with a Canonical Principal Direction
(Istanbul Technical Univ, 2017)
In this paper, we would like to give a short survey of recent results on hypersurfaces with canonical principal direction relative to a fixed direction in a (semi-)Riemannian manifold. We also present some of our first ...
Product of the Generalized L-Subgroups
(Hindawi Ltd, 2016)
We introduce the notion of (lambda,mu)-product of L-subsets. We give a necessary and sufficient condition for (lambda,mu)-L-subgroup of a product of groups to be (lambda,mu)-product of (lambda,mu)-L-subgroups.
Analysis of Fossil Pollen Record from the Late Holocene in the Turkish Highland (Middle Taurus, Turkey)
(Wydawnictwo Uniwersytetu Mikolaja Kopernika, 2017)
In this study, we have investigated changes of vegetation in the Mediterranean Region of Turkey approximately for the last 5000 years using pollen analysis. There were some differences in the past vegetation, but principally ...
Avalanche susceptibility and risk analysis of Eastern Anatolian region using GIS
(Elsevier Science Bv, 2014)
Turkey faces various natural disasters due to her geographical location. One of these natural disasters is avalanches. Eastern Anatolia Region which covers 21 % of Turkey's land, 163.000 km(2) surface area is the region ...
How was the Anatolian side of Istanbul formed? A geomorphologic assessment (NW Turkey)
(Elsevier Science Bv, 2014)
This study investigates the Geomorphological evolution of Anatolian side of Istanbul. This area is one of the most problematic and most discussed areas in the Near East geography. There is no detailed contemporary geological ...
Soil erosion estimation in lower Asi river catchment using GIS
(Elsevier Science Bv, 2014)
Different methods are used to calculate the amount of erosion. Assessment of erosion factors through the use of spatial data integration is the most common method. Generally, RUSLE (3D) erosion model is preferred in the ...
Determination of height profile from a two-dimensional fringe signal using a two-dimensional continuous wavelet transform
(Scientific Technical Research Council Turkey-Tubitak, 2017)
The main objective of this study was 3-dimensional (3D) profile measurements with standard fringe projection, consisting of a CCD and a projector. For obtaining height information of objects pixel by pixel, phases have to ...
Cylindrically symmetric vacuum solutions in higher dimensional Brans-Dicke theory
(Amer Inst Physics, 2010)
Higher dimensional, static, cylindrically symmetric vacuum solutions with and without a cosmological constant in the Brans-Dicke theory are presented. We show that for a negative cosmological constant and for specific ...
