Although cryoconite holes, sediment-filled melt holes on glacier surfaces, appear small and homogenous, their microbial inhabitants may be spatially partitioned.This partitioning could be particularly important for maintaining biodiversity in holes that remain isolated for many years, such as in Antarctica.We hypothesized that cryoconite holes with
Compared to traditional high-pressure die casting (HPDC), horizontal squeeze casting (HSC) is a more promising way to fabricate high-integrity castings, owing to a reduced number of gas and shrinkage porosities produced in the casting.In this paper, the differences between HSC and HPDC are assessed, through which it is shown that the Hammock Parts
The ink used by Volta in his scripts appears to be a very complex mixture.Our analysis of the eluates from the EVA diskettes (via GCXGC/TOFMS) has revealed the presence of more than 1800 unique metabolites.The ink thus appears to be a very complex combination of different ingredients, mainly consisting of tannins, vegetable oils and resins together
