ABSTRACT
Nickel was sputter deposited on a glass with a thin film thickness of 600 nm under either in an argon atmosphere or under a partial pressure of nitrogen of either 1.3 x 10(-4) or 4 x 10(-4) mbar. Atomic force microscopy and scanning surface potential microscopy (SSPM) were used to study the morphology and to estimate the surface resistivity of the obtained Ni thin films taking into account surface-roughness effects. For the three samples investigated, the surface resistivity values as estimated using SSPM were in good agreement with the results obtained by standard four-point probe measurements.
ABSTRACT
PIP: Changes in mortality caused by circulatory disorders in Bulgaria are examined using data for the period 1975-1985. Consideration is given to cerebrovascular effects and ischemic heart disease, sex and age factors, and residence characteristics. The need to lower the morbidity and mortality rates caused by these diseases is stressed. (SUMMARY IN ENG AND RUS)^ieng

PIP: Problems concerning the measurement of the health status of Bulgaria's population are described. In particular, the author assesses the use of census data for this purpose. The use of surveys to collect health status data to supplement census data is also considered. (SUMMARY IN ENG AND RUS)^ieng

"The author characterizes the state and tendency towards change in trauma- and poisoning-inflicted mortality in Bulgaria for the 1970-1984 period. The analysis comprises not only the general coefficients, but also mortality by sex, age and place of living of the deceased, as well as some comparisons with similar processes in other countries." Data are from official and other published sources. (SUMMARY IN ENG AND RUS)

PIP: The results of a study of fertility trends in the Burgas district of Bulgaria are presented. The study was designed to examine reasons for the recent decline in fertility. The authors conclude that an increase in fertility can only be achieved by social changes that would encourage people to have more children. (SUMMARY IN ENG AND RUS)^ieng
