Since their independence, the countries of Africa have become more and more aware of the importance of traditional medicine, and some countries are channelling substantial aid into re-emphasizing its value. The inadequate health coverage of rural populations in Africa has led WHO, and in particular its Regional Office for Africa, to introduce a new approach based on simpler and more accessible measures and recommending, among other things, the use of traditional medicine...

There are certain human values that are or should be sacred in all cultures; social justice is one of them. It is on this value of social justice that the objective of Health for All by the year 2000 is based. What, indeed, could be more just than a world in which every woman and man can enjoy a level of health that permits her or him to lead a socially and economically productive life? That is why this challenge has touched a raw nerve in all societies. Social justice h...

By: C. Marcolli; D. A. Pedernera; T. Koop; B. Zobrist

Description: Institute for Atmospheric and Climate Science, ETH Zurich, Zurich, Switzerland. A new process is presented by which water soluble organics might influence ice nucleation, ice growth, chemical reactions and water uptake of aerosols in the upper troposphere: the formation of glassy aerosol particles. Glasses are disordered amorphous (non-crystalline) solids that form when a liquid is cooled without crystallization until the viscosity increases exponentially...

Description: School of Earth, Environmental and Atmospheric Science, University of Manchester, UK. Solid state vapour pressures of a selection of substituted dicarboxylic acids have been measured using Knudsen Effusion Mass Spectrometry (KEMS). Enthalpies of fusion and melting points obtained using Differential Scanning Calorimetry (DSC) were used to obtain sub-cooled liquid vapour pressures. They have been compared to estimation methods used on the E-AIM website. T...

Description: School of Earth and Environment, University of Leeds, Woodhouse Lane, Leeds LS2 9JT, UK. Iodine oxide particles are known to nucleate in the marine boundary layer where gas phase molecular iodine and organoiodine species are produced by macroalgae. There has been some debate over the chemical identity of these particles. Hygroscopic measurements have been used to infer that they are composed of insoluble I2O4, while elemental analys...

Description: R&D Center, Samsung Engineering Co. Ltd., 415-10 Woncheon-Dong, Youngtong-Gu, Suwon, Gyeonggi-Do, 443-823, Korea. The presence of N-nitrosodimethylamine (NDMA) in drinking water supplies has raised concern over its removal by common drinking water treatment processes. However, only limited studies have been examined to evaluate the potential removal of NDMA by numerous water treatment technologies within a realistic range (i.e., sub Μg/L) of NDMA ...

The mechanical response of a dense granular material submitted to indentation by a rigid flat punch is examined. The resultant deformation is viewed as a process of self-organisation. Four aspects of the mechanical response (i.e. indentation resistance, failure, Reynolds' dilatancy, the undeforming dead zone) are explored with respect to the linear and cyclic st...
