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 ...
Development of a Prototype Machine Shop Safety System for Vocational Training
(Gazi Univ, 2015)
In this research, a sample of machine shop safety automation was designed in order to prevent occupational accidents taking place in machine shop environments. The developed prototype system is a special occupational safety ...
Memristor-based series voltage regulators
(Slovak Univ Technology, 2019)
Series linear voltage regulators are integrated circuits commonly used to make adjustable voltage sources. When used with potentiometers, these regulators are able to give adjustable voltage at the output. Memristor is a ...
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 ...
Effect of Pure Biodiesel on Fuel Injection Systems and Noise Level in Agricultural Diesel Engines
(Farm Machinery Industrial Research Corp, 2010)
Petroleum fuels have caused environmental problems that affect the whole atmosphere and some estimate the depletion of petroleum in 50-100 years. Mankind has turned their attention toward alternative, renewable energy ...

(2010)
Petroleum fuels have caused environmental problems that affect the whole atmosphere and some estimate the depletion of petroleum in 50-100 years. Mankind has turned their attention toward alternative, renewable energy ...
Comparing quality of free range and battery cage eggs
(Eugen Ulmer Gmbh Co, 2017)
Quality parameters of eggs from laying hens kept in free-range respectively battery cage systems were compared. Lohmann Brown laying hens (n = 75) from 24 to 30 wk of age were used in the study. Feed and water were available ...
