Redistribution of nutritive elements in a 'Gros Michel' banana plant.
A procedure is described and leaf, rhizome and root analyses are presented for a one-year-old vegetative plant of the banana cv. Gros Michel grown under glass in a sandy soil supplied with organic and inorganic fertilizers. Silicon was used as an index element on the presumption that it is not redistributed within a plant. The results indicated that N, S, P, K and Cu were mainly redistributed into young leaves from the old leaves, the rhizome functioning as a circulation pump. In contrast, only small amounts of Mg, Cl, Fe and Zn (and no Ca) were redistributed. Most redistribution of N and S was in the organic, rather than inorganic, form of each element.

Het college en de rechtbank hebben de twee gedragingen waaraan appellant zich heeft schuldig gemaakt terecht gekwalificeerd als zeer ernstig plichtsverzuim. Hierbij is in ogenschouw genomen dat appellant een functie bekleedt, waarin hij activiteiten organiseert en uitvoert waarbij kinderen aan zijn zorgen en toezicht worden toevertrouwd. Dat een van de gedragingen zich in de privésfeer afspeelde sluit niet uit dat deze gedraging plichtsverzuim kan opleveren. Hiervan is in dit geval sprake, nu van appellant gezien zijn functie mocht worden geëist dat hij (ook in seksueel opzicht) van onbesproken gedrag is. Nu niet is gebleken dat de gedragingen niet aan appellant kunnen worden toegerekend, was het college bevoegd appellant een disciplinaire straf op te leggen
Reactivity and selectivity in glycosylation reactions
The glycosylation reaction is a pivotal reaction in
creating new and complex oligosaccharides. These biologically relevant
compounds must be obtained in enough quantity and in pure, well-defined form.
Organic synthesis can provide these compounds, but efficient methods
regarding their selective synthesis are often absent. Every saccharide
building block is coupled to another in a glycosylation reaction, which must
be both regioselective and stereoselective. For the stereoselectivity of this
reaction common protocols are not generally applicable. This thesis
investigates the stereoselectivity of the glycosylation reaction from the
standpoint of the sugar acceptor, rather than from the sugar donor which has
been the focal point for many decades. The results obtained showed that a
scale of selectivities can be obtained by changing the reactivity of the
acceptor. The trends within the acceptor reactivity are valid for all donors
studied, but some donors are more susceptible than others to changes in
acceptor reactivity. In the second part of this thesis the spatial identity
of intermediates in the glycosylation reaction are investigated. Experimental
and computational techniques combined resulted in an effective model to
understand the glycosylation reaction on the SN1-side of the reaction
spectrum when different functional groups are located on the carbohydrate
donor.

The crucible of war: Dutch and British military learning processes in and beyond southern Afghanistan
How armed forces adapt to operational challenges has been a salient subject in War Studies in recent years. However, the process of institutionalization of such lessons post-conflict has received less attention. This study seeks to examine military learning processes during missions and beyond. By synthesizing organizational learning theories with the literature on military innovation, it argues that there are distinct but related forms of learning during and after operations that are subject to peculiar dynamics. Specifically, this research analyzes Dutch and British learning processes during operations in southern Afghanistan and their enduring impact on the respective military organizations. The Dutch and British experiences and institutionalization efforts are reconstructed based on archival records, policy documents, official evaluations and over one-hundred interviews with service members, civil servants and scholars with direct involvement in the Uruzgan and Helmand campaigns during the most volatile years in the Afghanistan war and their aftermath.Royal Netherlands ArmySecurity and Global Affair
