A comparative study on the spatial origin and development of towns in the northern Netherlands, 700-1400.

In meta-analysis, heterogeneity often exists between studies. In such cases, it is essential to investigate the sources of heterogeneity and understand the relationship between effect size and study characteristics (i.e., moderators).

This thesis is based on five papers on several topics.

What are the flows of C&DW (e.g. bricks, concrete, gypsum and wood) in the case study countries ? How to define the specification for each material to be quantified? What indicators should be used to identify the pattern of each C&DW management system? How to interpret the MFA results in relation…

A new study published in Archaeometry describes the unexpected results obtained from analyses of five human teeth discovered in a ritual cache at an enslaved African plantation site on the island of Saba in the Caribbean.

PURPOSE: In the present study we investigated the root-cause of an interference signal (100-200 nm) of sugar-containing solutions in dynamic light scattering (DLS) and nanoparticle tracking analysis (NTA) and its consequences for the analysis of particles in biopharmaceutical drug products.

Survival Analysis for Junior Researchers 2018 was hosted in Leiden.

The arrival of Columbus to the Caribbean in 1492 marked a milestone in world history. In both the European and the indigenous world, a set of economic, political and hierarchical networks and relations were defined, structured and changed.
