This paper provides detailed description of a non-destructive, low-cost, and low-time consuming technique for producing high-resolution casts for the observation of taphonomic modifications on bone surfaces. The aim of the whole process is to obtain molds that accurately replicate the original bone surface at both the macroand microscopic levels. The high quality transparent epoxy casts produce...

It can take ages to meet the right partner. So much so that plants lost their patience millions of years ago and thought up something else: the art of selfing. Many flowering plants are indeed capable of extensive in-breeding – by way of a rather subtle form of hermaphroditism – to ensure their spread and survival. The common mouse-ear cress, Arabidopsis thaliana, which has become the model pla...

Do-it-yourself Reflection

We wrote down this collection of design patterns, because they describe well-known practice. They all have been used in building flexible systems or frameworks. We call them “doit-yourself reflection”, because they follow some of the principles of reflective systems, accessing program elements by the program itself. They index program elements by data values (e.g. strings as names) not by progr...
