[Mathematical modeling and prognosis of incidence of enteric anthroponoses with aqueous route of transmission].

Using data on long-term dynamics of epidemic process of acute enteric infections enteric with aqueous route of transmission (typhoid fever, shigellosis caused by Shigella flexneri, hepatitis A, rotavirus gastroenteritis, etc.)the equation of regression was developed with the help of Chebyshev's polynoms. Predicted incidences of these infections for 2005 were on 61.

[A new generation of acaricide--attractant acaricidal granules].

The paper gives a brief account of the earlier results of papers with the development of attractive acaricidal granules (AAGs) and the results of their field tests in Tyumen Province and Krasnoyarsk Territory. AAGs in combination with sumithion yielded the best results than those with permethrin: their efficacy was over 90% and their action lasted 1.5 months.
