A13-STRACT :The conbustion of untreated Bulgarian brown coals
of 12-M~ ash content containing 12-455c moiature
-ind 0.26-1.4'% (working fuel bas~,s (sic]) at
power generatinT plants requires 'the frequent
cleartiaS of the flues from a&YL deposits. Calagging]
and leads to the corrosion of metallic surfacez,
damages, ourrounding vegetation, etc, The author
has made a7'study of methods for achiovLn~, an im-
proved utilization of brown coals and recommends
tae preliminary drying of the coal cefore combuo-
tion as well as the utilization of special slag
ging-type furnaces.

TITLE: Approximation formula for the extension in the conformal
mapping of an area with a narrow slection

TEXT: Lavrentlyev (M. A. Lavrehttyev, B. V. Shabat, Metody teorii funktsiy
kompleksnogo peremennogo (Methods of a*theory of functions of a complex
variable), Gostekhizdat, M., 1958) has'devised a method of estimating the
absolute amount of the derivative at the boundary of a conformal mapping w
of a-narrow domain onto a strip of constant width. This estimate is proved
under weaker conditions: conditions are imposed on.the boundary of the
-domain.to be mapped only in the neighborhood of the point considered;
conditions concernihg the entire domain are dropped. The estimate proved
