## Abstract Long term loosening of hip prostheses remains an important problem in orthopedics. Although various loosening mechanisms have been proposed, the exact process is still unclear. Particle disease and the pressure theory are widely known and generally accepted hypotheses to explain long te

β¦ Synopsis
The ecophysiological propertieslight effectuated neosynthesis of biomass from inorganicsmake microalgae become interesting organisms of preventive and sanitating environmental protection with regard to the inorganic impact. They are filling an underestimated gap. Medium-term solutions of the heavy metal accumulation in the tertiary sewage disposal, the trophy sanitation of surface and ground waters and of algal induced recultivation of waste-land seem to be attainable. The investigation of the role of microalgae in world-wide material cycles will be of long-term importance to biotechnology and global ecology.

In this study, the survival of genetically engineered microorganisms (GEMs) and their interactions with the environmental microbiota of a tropical river was investigated. Diffusion chambers were used for the in situ survival experiments with a nonplasmid containing Escherichia coli DH7 strain and tw
## Abstract This discussion paper presents a framework for spatiotemporal differentiation in ecological protection goals to assess the risks of pesticides in surface waters. It also provides a proposal to harmonize the different scientific approaches for ecotoxicological effect assessment adopted i
