The results of complex social and ecologic study in the city of Ufa

The authors present results of social and ecologic study carried out in Ufa. The results describe the course of ecologically important processes and phenomena in correlation with the public subjective understanding. Public health is influenced by hygienic parameters of food and water quality as well as a complex of social, economic and psychologic factors. Weak correlation between those parameters and ambient air pollution necessitates more accurate approach to ecologic mapping of cities and to manipulation with data on lower atmosphere pollution with chemical hazards.

Perfection of methodical approaches to designing vaccines against tick-borne encephalitis

Nine female patients with a urethral diverticulum were admitted to our center over a six period: The clinical symptomatology was not specific. The diagnosis has been performed by voiding and retrograde cysto-uretrogram. The surgical treatment consisted in the excision of the diverticula, with the patient in the supine position. No perioperative morbidity was observed.

INCORPORATING PRACTICAL AND SYNTHESIS CONTENTS IN UNDERGRADUATE CONTROL EDUCATION

This paper revisits the effort over the last decade in making undergraduate control education more useful and attractive to both the control engineers and the engineers at large. With the help of further coverage in new textbooks, more practical and synthesis contents in the control courses have been incorporated. Gaps still exist, particularly in the areas of PID control and auto‐tuning, fuzzy control, overall control strategy, control structure and systems thinking, and these will be elaborated. A major challenge is in the coverage of more practical and synthesis contents in the introductory common control course for all engineers. How this may be resolved is discussed. Finally, the need for new teaching approaches such as the use of interesting case studies and the use of problem‐based learning will be outlined.     

The role of dopamine in the mechanism of the regulation of the digestive-transport functions of the enterocyte membrane during stress

The L-DOPA and sulpiridinum effects on the enzymatic transporting function of the enterocytes' membrane, were studied in rats under stress. The L-DOPA was shown to hinder the absorption rate of glucose, whereas sulpiridinum was shown to suppress the main enzymes excepting snerase and alkaline phosphatase, to increase the monomeric and hydrolysate glucose transport. The L-DOPA seems to play a modifying role in the regulation and integration of the digestive-transporting function of the enterocytes' membrane in rats under stress.

Pseudorandomness of Basic Structures in the Block Cipher KASUMI

The notion of pseudorandomness is the theoretical foundation on which to consider the soundness of a basic structure used in some block ciphers. We examine the pseudorandomness of the block cipher KASUMI, which will be used in the next‐generation cellular phones. First, we prove that the four‐round unbalanced MISTY‐type transformation is pseudorandom in order to illustrate the pseudorandomness of the inside round function FI of KASUMI under an adaptive distinguisher model. Second, we show that the three‐round KASUMI‐like structure is not pseudorandom but the four‐round KASUMI‐like structure is pseudorandom under a non‐adaptive distinguisher model.
