Consequences for sediment stability and seston trapping

On 17 August 1945, two days after the Japanese surrender that also brought an end to the Second World War in Asia, Indonesia declared its independence. The declaration was not recognized by the Netherlands, which resorted to force in its attempt to take control of the inevitable process of decolonization.…

This article tries to examine if one can take the 'One Net' for granted, since the world becomes increasingly fragmented with social and geopolitical tensions. Furthermore, the author seeks to discover what is at stake if the global interoperable network is under a threat of fragmentation.

Statistical considerations guide the design and implementation of the experiments that scientists perform. For instance, in a clinical trial about a the efficacy of a treatment, its effect in a certain minimum amount of patients has to be observed in order to make confident assertions about the efficacy…

Nanoparticles can be used as delivery systems for both small molecules and macromolecules such as proteins, peptides or oligonucleotides. This thesis focuses on the use of liposomes, nanometric vesicles formed by a lipid bilayer enclosing an aqueous core. Liposomes are highly versatile delivery syst…
