Investigation of Inland Pollution Using Total Carbon (Tc), Total Organic Carbon (Toc), Inorganic Carbon (Ic), Total Nitrogen (Tn) and Toc/Tn Ratios
(Corvinus Univ Budapest, 2019)
In this study, sediment samples were taken at three different points in Edremit Bay at different depths from the sea floor. In Edremit Bay, it was investigated whether the pollution was marine or terrestrial. According the ...
An economic analysis of the effect of a government institution's purchase quantities on the wheat market in Turkey
(Univ Philippines Los Banos, 2012)
Wheat is under cultivation in Turkey over an area of approximately 9.3 million ha, which on the average, produces 20 million tons of wheat annually. Wheat production occupies approximately 35% of the agricultural land in ...
Facile synthesis of the azocino[4,3-b]indole framework of strychnopivotine and other Strychnos alkaloids
(Springer, 2016)
A new synthetic route to the 1,5-methanoazocino[4,3-b]indole is described. The aim of the present study is to provide a tetracyclic skeleton for the synthesis of pentacyclic Strychnos alkaloids (tubifolidine and ...
Selective oxidative deoximation with anhydrous Ce(IV) sulfate
(Pergamon-Elsevier Science Ltd, 2015)
Anhydrous Ce(SO4)(2) in chloroform selectively converts oximes into the parent carbonyl compounds in good yields. Hammett correlations helped to indicate a plausible mechanism for the above reaction. The formation of ...
Antioxidant activity of five new phenolic compounds from Cirsium creticum subsp. creticum
(Elsevier Science Bv, 2019)
In this study, five new alkyl catechol derivatives, 1, 2, 3, 4 and 5 were isolated for the first time from Cirsium creticum subsp. creticum L. and their structures were determined by using spectroscopic techniques, including ...
The memristive system behavior of a diac
(Springer, 2020)
The memristor was introduced as a nonlinear circuit element in 1971, and systems showing memristor-like properties such as zero-crossing hysteresis loops were described in 1976. In 2008, a thin-film system that behaved ...
Reconstructive sensing circuit for complementary resistive switches-based crossbar memories
(Tubitak Scientific & Technical Research Council Turkey, 2016)
Complementary resistive switches (CRSs) are suggested as an alternative to one-cell memristor memories to decrease leakage currents. However, their sensing is more difficult and complex than one-cell memristor memories. A ...
Solution of TiO2 memristor-capacitor series circuit excited by a constant voltage source and its application to calculate operation frequency of a programmable TiO2 memristor-capacitor relaxation oscillator
(Tubitak Scientific & Technical Research Council Turkey, 2015)
The memristor is a new-found circuit element and its applications in programmable circuits are also under study. Analysis of most of its combinations with other circuit elements such as resistors, capacitors, and inductors ...
A new pyran derivative analog from the whole plant of Cirsium italicum
(Taylor & Francis Ltd, 2021)
The aim of the present article was to analyze the phytochemical composition of EtOAc extract ofCirsium italicum(Savi) DC. and to determine the antioxidant activity of a new compound1. The EtOAc extract ofC. italicumwas ...
Memristor-Based Phase Shifter
(IEEE, 2018)
Memristor is a new nonlinear circuit element. It is a special case of memristive systems. It has a charge-dependent resistance and a frequency dependent hysteresis curve when excited with an AC source. It has been claimed ...
