The Project "Strategies and mechanisms for promoting investments in cleaner production in developing countries", implemented by UNEP/DTIE 1 has amid its objectives to build capacity of industry and financiers in assessing cleaner production (CP) based investment proposals, in selected pilot countries . The project has generated training programmes, mainly targeted at industrialists, government ...
BACKGROUND Over half the world is exposed daily to the smoke from combustion of solid fuels. Chronic obstructive pulmonary disease (COPD) is one of the main contributors to the global burden of disease and can be caused by biomass smoke exposure. However, studies of biomass exposure and COPD show a wide range of effect sizes. The aim of this systematic review was to quantify the impact of bioma...
Environmental concerns have highlighted the need of cleaner technologies. A cleaner, convenient and selective technology has been developed for the preparation of 3-(4,6-dimethoxy-pyrimidin-2-yloxy)-2-methyl-phenol (DPMP) from 2-methyl-benzene-1,3-diol in water as solvent. The isolated yield of DPMP is up to 86% in good selectivity. The product structure was characterized by conventional method...
Household contamination with Salmonella enterica increases when occupational exposure exists (cattle farms with known salmonellosis in cattle, a salmonella research laboratory, or a veterinary clinic experiencing an outbreak of salmonellosis). Fifteen of 55 (27.2%) vacuum cleaner bags from households with occupational exposure to S. enterica were positive versus 1 of 24 (4.2%) without known exp...

One of the most notorious examples of cooperation between different species happens in the cleaner-client fish mutualism. The best known cleaner fish species, the bluestreak Indo-Pacific cleaner wrasse Labroides dimidiatus has been a model system to study the evolution of cooperation between unrelated animals and between distinct species during the last couple of decades. Given that the cleaner...

Nanotechnology, the engineering of func tional materials at an atomic or molecular scale, has been among the fastest growing fields of science and technology. Worldwide sales of products incorporating nanotechnolo gy are projected to total $2.6 trillion by 2014, according to a 2004 report from Lux Research titled Sizing Nanotechnology’s Value Chain. But with the increasing use of nano materia...
