Pedestal Structure and Energy Confinement Studies on TCV

Olivier Sauter, Basil Duval, Patrick Blanchard, Benoît Labit, Christian Gabriel Theiler, Antoine Pierre Emmanuel Alexis Merle, Umar Sheikh, Cedric Kar-Wai Tsui

High external gas injection rates are foreseen for future devices to reduce divertor heat loads and this can influence pedestal stability. Fusion yield has been estimated to vary as strongly as

Nitrogen-enriched compost application combined with plant growth-promoting rhizobacteria (PGPR) improves seed quality and nutrient use efficiency of sunflower

Alexandre Buttler, Luca Bragazza, Muhammad Saleem Arif, Muhammad Riaz

Ecological benefits associated with plant growth-promoting rhizobacteria (PGPR) inoculants offer a promising integrated nutrient management option to counteract plant nitrogen (N) deficiency. We performed field experiments to evaluate the effect of integra ...

An anomalous metal-rich phosphogypsum: Characterization and classification according to international regulations

Phosphogypsum is the main waste generated by the phosphate fertilizer industry. Despite the high level of pollutants found in phosphogypsum and the proximity of stacks to cities, there are no specific regulations for the management of this waste. This stud ...

Combined Exergy Analysis and Energy Integration for the Optimization of Nitrogen Fertilizer Plants

François Maréchal, Daniel Alexander Florez Orrego, Shivom Sharma

Modern ammonia production plants are equipped with efficient energy integration networks able to recover an important fraction of the enthalpy of reaction released by the exothermic chemical systems. However, to fully supply the exergy demands of the highl ...

Mechanisms and modeling of pathogen fate in pilot scale nutrient recovery reactors

Loïc Decrey, Simon Schindelholz, Manfred Schoger, Ariane Schertenleib, Timothy R. Julian

Due to its high nutrient content, source-separated urine can be processed into marketable liquid or solid fertilizers. The Valorisation of Urine Nutrients in Africa (VUNA) project developed and tested pilot-scale nitrification/distillation and struvite (Mg ...

Nitrate formation during ozonation as a surrogate parameter for abatement of micropollutants and the N-nitrosodimethylamine (NDMA) formation potential

Urs von Gunten, Florian Frédéric Vincent Breider, Jun Ma, Yang Song

In this study, nitrate formation from ammonium and/or dissolved organic nitrogen (DON) was investigated as a novel surrogate parameter to evaluate the abatement of micropollutants during ozonation of synthetic waters containing natural organic matter (NOM) ...

Nitrification increases nitrogen export from a tropical river network

Janine Rüegg

Scaling aquatic ecosystem processes like nutrient removal is critical for assessing the importance of streams and rivers to watershed nutrient export. We used pulse NH4+ enrichment experiments and measured net NH4+ uptake in 7 streams throughout a mountain ...

Life Cycle Assessment of Thermochemical Conversion of Empty Fruit Bunch of Oil Palm to Bio-Methane

Edgard Gnansounou, Paolo Montafia

The energy demand is increasing as well as the GHG emissions and the fossil fuels depletion. Public awareness on this topic significantly raised up in last decades. Nowadays conversion of residual biomasses in energy represents a real opportunity. However, ...

Effect of crop rotation on mycorrhizal colonization and wheat yield under different fertilizer treatments

Pierre Rémi Mariotte

Break crops are used in agriculture to reduce soil pathogens and improve yield of subsequent cereal crops. However, they can also affect soil microbial communities beneficial to plant growth including arbuscular mycorrhizal fungi (AMF). Two wheat genotypes ...

Impact of nitrogen inputs on multiple facets of plant biodiversity in mountain grasslands: does nutrient source matter?

François Gillet

Questions: What is the impact of nitrogen (N) inputs on the vegetation of mountain permanent grasslands? Beyond the effect of fertilizer quantity (total and available N supply), is there a specific effect of fertilizer quality (the various N sources) on th ...
