The electric field fire extinguishing technology is an efficient, clean, and new that can be operated at a long distance. In order to study the synergistic mechanism of “electric-flow-heat” in process transverse AC extinguishing, ionic wind formed by influence on each charged particle during burning ethanol–air diffusion flame simulated non-premixed combustion model, experimental phenomenon que...

Lichens, a symbiotic relationship between a fungus (mycobiont) and a photosynthetic green algae or cyanobacteria (photobiont), belong to an elite group of survivalist organisms termed resurrection species. When lichens are desiccated, they are photosynthetically inactive, but upon rehydration they can perform photosynthesis within seconds. Desiccation is correlated with both a loss of variable ...

We present a splitting moving mesh method for multi-dimensional reaction-diffusion problems with nonlinear forcing terms over rectangular domains. The structure of the adaptive algorithm is an elegant combination of an operator splitting and one-dimensional moving mesh. It is motivated by the nature of splitting method, which splits a multi-dimensional problems into a few one-dimensional proble...

A number of problems of solar and stellar dynamo theory are briefly reviewed and the current status of possible solutions is discussed. Results of direct numerical simulations are described in view of mean-field dynamo theory and the relation between the α-effect and the inverse cascade of magnetic helicity is highlighted. The possibility of 'catastrophic' quenching of the α-effect is explained...

a sensitive and fast chemiluminescence (cl) method has been described for the direct determination of atropine. the method is based on the quenching effect of atropine on the cl signals of the luminol– h2o2 reaction catalyzed by hemin in an alkaline medium. hemin could strongly enhance the chemiluminescence of the luminol–h2o2 system. the luminophor of the luminol–h2o2–hemin cl system was ident...

bacteria use a chemical language to communicate with each other which enables them to synchronize gene expression as a result of cell density. this special language which is called quorum sensing (qs) is based on producing and sensing the small signals and eventually leads them to perceive when a minimum population unit is reached. on the contrary, quorum sensing blockade (quorum quenching) has...

The linear peptide gramicidin forms prototypical ion channels specific for monovalent cations and has been extensively used to study the organization, dynamics, and function of membrane-spanning channels. We have analyzed the localization of the functionally important tryptophan residues of the membrane-bound channel and non-channel conformations of gramicidin utilizing a novel dual fluorescenc...

Recently, we pointed out that chiral transformation properties of penguin operators change in the transition from unquenched to (partially) quenched QCD. As a consequence, new operators appear in (partially) quenched QCD penguins, introducing ambiguities which should be considered a quenching artifact. Here we discuss more specifically the effects of this phenomenon on the quenched ∆I = 1/2 K →...

To model the dynamics of the chiral order parameter in a far from equilibrium phase transition, we consider quenching in the O(4) linear sigma model. We argue, and present numerical evidence, that in the period immediately following the quench long wavelength modes of the pion field are amplified. This results in large regions of coherent pion oscillations, and could lead to dramatic phenomenol...
