Growth performance and health status in weanling piglets fed spray-dried porcine plasma under typical Northern European conditions

Autor: R. J. C. F. Margry, A.J. van Dijk, A. C. Beynen, A. G. Van Der Lee, G. Hemke

Publikováno v: Journal of Animal Physiology and Animal Nutrition. 86:17-25

The effect of inclusion of spray-dried porcine plasma (SDPP) in diets for weanling piglets was studied. The objectives were to determine whether SDPP would have positive effects on post-weaning piglet performance and health under typical Northern Eur

Aluminium species and pH in soil solution under different crops

Autor: R. L. Parfitt, G. van der Lee, H. J. Percival

Publikováno v: Plant-Soil Interactions at Low pH: Principles and Management ISBN: 9789401040990

The concentration of monomeric Al in soil solution was estimated using both chrome-azurol-S (CAS) and pyrocatechol violet (60 sec) (PCV). In some samples the concentrations measured with PCV were greater than with CAS, suggesting PCV was less discrim

On the selectivity of Rh catalysts in the formation of oxygenates

Autor: G. van der Lee, H. Post, T.L.F. Favre, B. Schuller, Vladimir Ponec

Publikováno v: Journal of Catalysis. 98:522-529

In order to gain information on the factors which determine the selectivity of catalysts in the syngas reactions, a number of Rh catalysts with various carriers have been studied. It has been found that Rh on V2O3 is, under certain conditions of prep

Selectivity of Rh catalysts in the syngas reactions. On the role of supports and promoters

Autor: G. van der Lee, W.J. van Der Boogert, B. Schuller, H.Y. Luo, A.G.T.M. Bastein, Vladimir Ponec

Publikováno v: Applied Catalysis. 29:243-260

Catalysts selective for C2-oxygenates can be prepared based on rhodium. However, a support and/or promoter is essential. It is shown that with V2O3 as a support, selective catalysts are only obtained when during preparation (wet steps, high temperatu

Adsorptive withdrawal of RhHCO(PPh3)3 in supported liquid phase hydroformylation catalysts

Autor: G. van der Lee, H.L. Pelt, J.J.F. Scholten

Publikováno v: Journal of Molecular Catalysis. 29:319-334

In supported liquid-phase catalysts the degree of pore filling may strongly influence the catalytic activity. This is the case, for instance, when dealing with supported liquid-phase rhodium catalysts in which the complex RhHCO(PPh 3 ) 3 , dissolved
