Noise map of cities and agglomerations

Noise map of city is an instrument for noise control. There are noise levels on all main roads, in people habitation and recreation areas, on the territory of industrial and other enterprises, and around isolated noisy objects. At present time in Russia and abroad the main problem of noise maps is as before the indefinite precision and reliability of indicated value of noise levels. With using of variance analysis method of probability theory and mathematical statistics the authors propose a method which helps in solving this problem

Comparative effects of limited tryptic hydrolysis on physicochemical and structural features of seed 11S globulins

The effect of the limited proteolysis by trypsin on selected seed storage 11S globulins (broad bean and pea legumins, glycinin and helianthinin) was studied by high-sensitive differential scanning calorimetry, fluorescence spectroscopy and analysis of proteolysis kinetics. Different behaviour of glycinin and helianthinin, on one hand, and broad bean and pea legumins, on the other, were observed: in the first group changes in the physicochemical characteristics of the proteins due to their limited proteolysis are more pronounced in comparison with the second one, in relation with the extent of primary structure modifications. The differences observed have been evaluated in relation with the amino acid sequence features of the four 11S globulin studied and agree with the literature data concerning the protein structural changes in the course of the limited proteolysis
