Eco-efficiency has become a cornerstone in improving the environmental and economic performance of farms. The joint use life cycle assessment (LCA) data envelopment analysis (DEA), known as LCA + DEA methodology, is an expanding area research this quest. estimates impacts products or services, while evaluates their efficiency, providing targets benchmarks for inefficient ones. Because energy co...

Le ar n ed D is co u rs es Intent. The intent of Learned Discourses is to provide a forum for open discussion. These articles refl ect the professional opinions of the authors regarding scientifi c issues. They do not represent SETAC positions or policies. And, although they are subject to editorial review for clarity, consistency, and brevity, these articles are not peer reviewed. The Learned ...

Nanotechnology is a science of producing and utilizing nanosized particles that are measured in nanometers. The unique size-dependent properties make the nanoparticles superior and indispensable as they show unusual physical, chemical, and properties such as conductivity, heat transfer, melting temperature, optical properties, and magnetization. Taking the advantages of these singular propertie...

Despite possessing an interesting chemical nature and tuneable physicochemical properties, ionic liquids (ILs) must have their ecotoxicity tested in order to be commercialized. The water solubility of ILs allows their easy access to the aquatic compartment of the ecosystem creating a potential hazard to aquatic organisms. Hence, it is relevant to design ionic liquids with lower toxicity while k...

Tidal energy is a reliable, consistent and abundant source of renewable energy. However, there are many concerns with different tidal devices relating to their environmental impacts over the lifetime. It essential address these issues by assessing technologies throughout all phases life cycle. In this context, cradle grave cycle assessment (LCA) study performed hereby on 1 MW Deepgen turbine. R...

waste is a by-product of our daily activities, which poses a serious threat to societies all over the world. in this study, life cycle assessment (lca) methodology was used to determine municipal solid waste (msw) management strategy for minna, niger state, nigeria. three scenarios were modelled as alternatives to the current waste management system in minna. the baseline scenario was the exist...

the acute ecotoxicity of a set of mixture samples (washing powders, wastes, fuel extracts etc.) was assessed using four acute ecotoxicity assays with aquatic organisms (daphnia magna, poecilia reticulata, artemia salina and desmodesmus subspicatus). the experimental concentration-response curves were fitted by seven two-parameter sigmoid equations using non-linear regression. the regression per...

The swine diet formulation in the United States of America (U.S.A.) is entering a new era decision making to promote low-carbon pork production systems. As part decision-making process, precision nutrition approaches customize and alternative feeding options that are economically viable environmentally sustainable given priority. Hence, objective this study identify an over standard corn–soybea...

Only 17 per cent of French households received digital television in 2002. Hence, for public authorities, digital terrestrial television (DTTV) is mainly a means to stimulate the development of digital television. However, cable and satellite operators (TF1, M6 and Canal Plus), which have been designated as leaders of the DTTV process, are reluctant, as they view DTTV as a competitor to their e...

Wireless sensor networks have emerged as a fastgrowing technology that has enabled us to monitor physical and environmental states. As of yet these valuable sensor networks have been bound to terrestrial terrains; however, seventy percent of the Earth’s surface is covered by enormous bodies of water: oceans, seas and rivers. Most of this territory remains unchartered, and this primarily gave a ...
