The Baylis-Hillman reactions of various aryl aldehydes with methyl vinyl ketone at temperatures below -20oC using Lewis acids such as titanium (IV) chloride, boron (III) chloride Money Box or zirconium (IV) chloride in the presence of a catalytic amount of selected amines used as a Lewis bases afford the chlorinated compounds 1 as the major product
Growing software complexity is an increasing challenge for the software development of modern cyber-physical systems.A classical strategy for taming this complexity is to partition system behaviors into different operational modes specified at design time.Such a multi-mode system can change behavior by switching between modes at run-time.A compleme
ABSTRACT: Translocation of rare populations is regarded as the last resort for the conservation of species whose habitat destruction is imminent.The objective of the present study was to evaluate the effect of two height classes and three leaf reduction intensities on growth and increases in height, stem diameter, survival, and new leaf production
Large signal profiles are commonly utilized BOSCH Serie 8 HBG6764B6B Electric Smart Oven - Black for estimating capacitor parameters in power converters, which typically requires current information.Installation of current sensors in practical power converters could be inconvenient and expensive.Existing current sensorless methods calculate the cur
Vegetable oils in the lubricant field Brake Block are largely studied.Their efficiency depends on their viscosity parameters and their fatty acid composition.The actions of moringa oil used as a lubricant base and as a lubricant additive have been shown in this work.Graphite, carbon nanofibers, and carbon nanodots are carbon phases of different sha
