Abstract:
... Reference collections of phytoliths from plant taxa commonly used by the ancient inhabitants of an archaeological site are critical to researchers conducting analyses on these microbotanical remains. Phytoliths recovered from the site are compared to those in reference collections to make inferences about which taxa were being used, as well as where, why and how. This study presents one of the fir ...

Abstract:
... School-based deworming programmes are currently the main approach used to control the soil-transmitted helminths (STHs). A key unanswered policy question is whether mass drug administration (MDA) should be targeted to the whole community instead, and several trials in this area have been conducted or are currently on-going. A recent well-conducted trial demonstrated that successful community-wide ...
