More conviction on HIV and AIDS

Article Abstract:

Haemophiliacs infected with human immunodeficiency virus (HIV) had ten times higher mortality rate than the uninfected haemophiliacs as revealed by report of a team of epidemiologists based on the records of the British National Haemophilia register. These statistics represent satisfactory evidence for the influence of HIV virus in mortality rates of AIDS patients. A total of 1,227 patients out of 6,287 patients in the register were infected during 1979-86. Patients' lifestyles were not considered in the studies to avoid confusion.

Regional trends in aquatic recovery from acidification in North America and Europe

Article Abstract:

Levels of acidic deposition from the atmosphere have fallen during the 1980s and 1990s over large areas of North America and Europe. This is believed by many to have led to observed reversals in surface-water acidification. Regional trends between 1980 and 1995 in indicators of acidification were examined and lak and stream sulphate concentrations were found to have fallen in all areas apart from Great Britain. However regional falls in lake and stream nitrate concentrations were rare, and if seen, were very small.

AIDS: trends, predictions, controversy

Article Abstract:

Many countries have established unlinked secret screening of HIV prevalence to study the trend of HIV spread. Previous studies suggest that AIDS is still at its early stages and there is a slowing of its spread among heterosexuals and homosexuals. Methods of extrapolation, complex mathematical models and back calculation methods have been applied to understand the trend of the spread of AIDS. Risk-prone groups should be educated about AIDS as a precautionary measure.
