Martin Martens (1797-1863) was a Belgian chemist and botanist who studied the oxychlorides obtained by the action of chlorides on metal oxides, and the theory regarding their formation.Chlorine decomposed calcium chloride at a temperature below 200 oC and calcium hydroxide at a lower temperature.In the presence of water the bleaching compounds gene
This paper aims to develop a novel hierarchical recursive nonsingular terminal sliding mode controller (HRNTSMC), which is designed to stabilize the inverted pendulum (IP).In contrast to existing hierarchical sliding mode controllers (HSMC), the HRNTSMC significantly reduces the chattering problem in control input and improves the convergence speed
The preventative and curative effects of some plant derived agents based on plant extracts or essential oils were studied at different concentrations against Erysiphe cichoracearum DC.ex Merat, the causal pathogen of okra powdery mildew by the detached leaf-disk and potted plants bioassays.Through detached leaf-disk assay, the highest mean preventa
There is discussed usage pattern of the nonlinear-in-the-parameter economic and mathematical models aimed at increase in efficiency of price elasticity of demand analysis mechanism and search of optimum fees for services of railway passenger transport within the solving framework of profitability management problems.Based on the qualitative charact
