Ammonia is heavily used in agriculture as a fertilizer and in industry as a raw material for the production of various organic nitrogen compounds. Its high hydrogen content and its established infrastructure for both storage and distribution makes ammonia a prominent candidate for storing fluctuating …

In this study, we present the e ects of time and temperature on the formation of urea deposits and their composition under conditions realistic to mobile heavy-duty SCR applications. To this end, various synthesis times were evaluated (1 h, 4 h and 24 h), as well as temperatures (298–673 K). The formed …

Background & aims: High protein delivery during early critical illness is associated with lower mortality, while energy overfeeding is associated with higher mortality. Protein-to-energy ratios of traditional enteral formulae are sometimes too low to reach protein targets without energy overfeeding. …

Background & aims Plasma citrulline concentration is considered to be a marker for enterocyte metabolic mass and to reflect its reduction as may occur during intestinal dysfunction. Strenuous exercise can act as a stressor to induce small intestinal injury. Our previous studies suggest that this comprises …

RATIONALE: Disturbed protein metabolism may result in malnutrition. A non-invasive low cost clinical tool to measure protein metabolism is lacking. Explorative research (n=1) with a newly developed non-invasive 13C-protein breath test suggested a decrease in protein oxidation after a protein restricted …

Result of the study on the exposure of imidacloprid on Lymnaea stagnails, have led to this study. The results indicate that imidacloprid might be metabolized to other components. Therefore the aim of the study was two folded: 1. To develop a method for the quantification of imidacloprid and its metabolites. …

ICL Fertilizers Europe C.V. has been trying to substitute ammonium sulfate with urea as nitrogen source in the fertilizer granules because urea has a higher mass percentage of nitrogen and is relatively cheaper. Several methods have been tested, including methods from previous experiments. The most …

The present study investigated the effect of salt (NaCl) intake on urea-N excretion by using milk urea level as an indicator. Sixteen multi-parity Dutch dairy Holsteins (daily milk production 27.74 ± 3.14 kg and body weight 654.9 ± 43.1 kg) were used in a 4x4 crossover design with treatment varying in …
