Push and Pull Systems
Data broadcasting has emerged as an efficient way for the dissemination of information over asymmetric wireless environments where the needs of the various users of the data items are usually overlapping. In such environments, data broadcasting stands to be an efficient solution since the broadcast of a single information item is likely to satisfy a possibly large number of users. Communication...
متن کاملPush-pull farming systems.
Farming systems for pest control, based on the stimulo-deterrent diversionary strategy or push-pull system, have become an important target for sustainable intensification of food production. A prominent example is push-pull developed in sub-Saharan Africa using a combination of companion plants delivering semiochemicals, as plant secondary metabolites, for smallholder farming cereal production...
متن کاملNitroaromatic compounds, from synthesis to biodegradation.
Nitroaromatic compounds are relatively rare in nature and have been introduced into the environment mainly by human activities. This important class of industrial chemicals is widely used in the synthesis of many diverse products, including dyes, polymers, pesticides, and explosives. Unfortunately, their extensive use has led to environmental contamination of soil and groundwater. The nitro gro...
متن کاملSynthesis of 1H-indazoles from N-tosylhydrazones and nitroaromatic compounds.
A new method for the synthesis of 1H-indazoles from readily available N-tosylhydrazones and nitroaromatic compounds has been developed. This transformation occurs under transition-metal-free conditions and shows a wide substrate scope. The method has been successfully applied to the formal synthesis of a bioactive compound, WAY-169916.
متن کاملPush and pull in Europe
Expansion of the EU now looks set to take place but the major efforts to develop common policies continue to be stymied by national differences, no more so than in on the issue of genetically modified (GM) crops, as Nigel Williams reports. But other moves are aiming to draw together Europeans in an effort to exploit closer collaboration as Michael Gross reports below.
