Microwave field energy as baker's yeast metabolism regulator

The influence of EMI EHF on physiological, morphological and technological characteristics of the bakery yeast growth in a wide frequency range has been investigated. Frequencies, significantly activating the yeast physiology, are defined. It is shown that impact effects persist during at least 250 generations. Changes in physiological activity, due to the radiation, are in good agreement with experimental data on enzymatic activity transformation of the key enzymes of yeast metabolism (β-fructofuranosidase, hexokinase, fumaratehydrotase). The action of EMI EHF on Saccharomyces cerevisiae yeast growth in the presence of azole and polyene groups of antibiotics, influencing on the formation of cytoplasmic membrane and yeast cell wall, has been studied too

Optimization of electromagnetic field excitation for microwave industrial and agricultural application

The aim of the paper is to discuss the modern approaches to the problem of electromagnetic field excitation efficiency improvement for operating chambers used for microwave industrial and agricultural applications.Problems of microwave excitation optimization are divided into two classes: optimisation under requirements for electromagnetic field intensity and in accordance with the different kind requirements for the temperature field distribution. Optimization problems accordingly to these two classes are formulated and calculation methods are discussed

Complex permittivity measurements in adaptive microwave complex

Complex permittivity measurement issues are under review in this work. After considering of all existing methods it was decided to choose one of them, that according to the expert point of view is the most perspective one for usage in microwave technological complex which are performing temperature and microwave processing of oil-inwater emulsion. Measurements are carried out on the same frequency as processing. Results of the experiments are given at the end

A dielectric lens collimator

In the given report the results of development of the simple collimator with an extended target zone on a basis of the dielectric lens with a rotational symmetry are presented. The increase of EM field uniformity in lens aperture is achieved because of a choice of the lens material with losses, and the decrease of total gain of the collimator is compensated by increasing of radiator gain. The experimental features of the collimator in the target zone also are shown
