The nucleophilic addition reaction of N-tosyl-4-oxo-4,5,6,7-tetrahydroindole (12) with the lithium salt of 1-methoxyindole (5), followed by dehydration with 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) gave the derivative of 2,4'-bi-1H-indole (9) which provides a new concise synthetic method of an indole pigment of the slime mould, arcyriacyanin A. The compound was first demonstrated here to...

Synchronized cells of the cellular slime mould Dictyostelium discoideum were prepared by mitotic wash-off. Cell counts and DNA synthesis measurements indicated a high degree of synchrony. Cells from each phase of the cell cycle were fluorescently labelled and mixed with unlabelled asynchronous cells. Cells that were in S-phase and very early G2 at the onset of starvation demonstrated a strong t...

The reduction in cell surface charge density during the early stages of differentiation of the cellular slime mould, Dictyostelium discoideum, has been studied by the technique of cell electrophoresis. Using specific chemical reagents, it was shown that the cell surface negative charge was probably due to side chain carboxyl groups of proteins. During differentiation, there was a decrease in th...

Solving the optimal power flow problems (OPF) is an important step in optimally dispatching generation with considered objective functions. A single-objective function inadequate for modern systems, required high-performance generation, so problem becomes multi-objective (MOOPF). Although MOOPF has been widely solved by many algorithms, new solutions are still to obtain better performance of ge...

The hypothesis of extended cognition (HEC) claims that the cognitive processes materially realise thinking are sometimes partially constituted by entities located external to an agent’s body in its local environment. We show how proponents HEC need not claim agent must have a central nervous system, or physically instantiate organised such way as play causal role equivalent brain if is be capab...
