Simple Analytical min-max Model Matching Approach to Robust PID Tuning
A simple negative feedback control loop makes the process variable close to the set-point even if there are disturbances. The common strategy is to develop a mathematical model of the process and, based on it, to select appropriate values...
Recyclable hybrid organocatalysts for the Knoevenagel condensation
Organocatalysis and heterogeneous catalysts provide certain advantages from both the economical and environmental point of view. Organic-inorganic hybrid materials have been prepared from imidazolium and dihidroimidazolium salts and turned out to be...
Discovery of the protein involved in the process of flower formation
An international group of researchers characterised the network of genes regulated by the transcription-factor (protein controlling the activation and inactivation of other genes) APETALA1, the authentic orchestra conductor of the flowering...
