Field Testing of a Novel Drilling Technique to Expand Well Diameters at Depth in Unconsolidated Formations.

Larger well diameters allow higher groundwater abstraction rates. But particularly for the construction of wells at greater depth, it may be more cost-efficient to only expand the borehole in the target aquifer. However, current drilling techniques for unconsolidated formations are limited by their expansion factors (<2) and diameters (<1000 mm).

Distinct osmoregulatory responses to sodium loading in patients with altered glycosaminoglycan structure: a randomized cross-over trial.

Background: By binding to negatively charged polysaccharides called glycosaminoglycans, sodium can be stored in the body-particularly in the skin-without concurrent water retention. Concordantly, individuals with changed glycosaminoglycan structure (e.g.

Sequencing of glycosaminoglycans with potential to interrogate sequence-specific interactions.

Technologies to sequence nucleic acids/proteins are widely available, but straightforward methodologies to sequence complex polysaccharides are lacking. We here put forward a strategy to sequence glycosaminoglycans, long linear polysaccharides involved in many biochemical processes. The method is based on the covalent immobilization and (immuno)chemical characterization of only those size-separated saccharides that harbor the original reducing end of the full-length chain.

The Final Fight: An Analysis of Metaphors in Online Obituaries of Professional Athletes.

In literature, obituaries from different cultures and languages have been studied on different levels and from different perspectives. One of the popular research topics is the use of metaphors, since metaphors help to cope with death, which in modern society is still a taboo. This article presents a bottom-up, primarily qualitative analysis of the metaphors in 150 obituaries of sportspeople, published in online versions of newspapers/magazines and on the Internet.
