| Iodine 129 discharged from nuclear fuel reprocessing plants in France and the United Kingdom is transported into the Nordic Seas on timescales of 3 - 5 years. Tracer I-129 is subsequently injected into intermediate waters that overflow the sills between Greenland, Iceland, and Scotland and ventilate the North Atlantic Deep Waters ( NADW). During the early 1990s, discharges of I-129 increased by 600%, resulting in a large, well- resolved tracer " front'' whose passage through the Nordic Seas is presently being observed by a time series of I-129 measurements on the WOCE ( AR7W) section in the Labrador Sea. The highest I-129 levels were measured below depths of 3000 m in Denmark Strait Overflow Water ( DSOW). These levels increased by about 300% between 1997... |

| ABSTRACT The intestinal health of piglets depends on the balance between diet, microflora and mucosal integrity. Disruption of this balance can compromise the digestive functions, leading to diarrhoeal frame and decline in performance of piglets. However, the level and type of fibre can limit digestive disorders. Thirty newly weaned piglets were used to evaluate the levels of neutral detergent fibre (NDF) in diets regarding performance, pH, viscosity and concentration of short chain fatty acids of digestive contents, gastrointestinal transit time, morphology of the intestinal mucosa, weights of organs and occurrence of diarrhoea. NDF level had quadratic effect on weight gain and feed conversion ratio of piglets, estimating best results at the level of... |
