Acta Crystallographica Section D Biological Crystallography, 2007
Crystallographers are increasingly determining structures of protein constructs that include His tags. Many have taken for granted that these tags have little effect on the native structure. This paper surveys and compares crystal structures with and without His tags.

On the structure of frictional impacts
Acta Mechanica, 2017Many processes in machines and mechanisms are accompanied by impacts with friction. They arise by short-time contacts between two or more bodies, and they generate energy losses mainly due to friction in tangential contact directions. During the last three decades, a couple of impact models based on the theory of rigid body contacts were established ...

Structural Examination of the Impact of Glycerol on Water Structure
The Journal of Physical Chemistry B, 2011The sugar alcohol glycerol is essential for cryopreservation, an important process used for the storage of biological molecules, cells, or tissues at low temperatures. A key hypothesis for the cryoprotective action of glycerol is that the glycerol molecule acts to modify the hydrogen bonding ability of water molecules, thus inhibiting ice formation. In

1987
Studies carried out in the last ten years resulted in the recognition of several circular structures in the Brazilian territory which have, as common characteristics, the presence of similarities with well-known structures in other countries and planets attributed to impact with celestial bodies, and the absence of evidence for a terrestrial ...

Meteorites and impact structures in Chad
Journal of African Earth SciencesThe large surface of Chad (fifth largest country in Africa) as well as a desert climate over much of its area, makes the country a potentially prolific place to recover meteorites and identify impact structures. However, only two meteorite finds have so far been reported, from Tibesti, and two probable falls have been recovered in the vicinity of the ...

Identification of Impact Structures
2013Confident criteria have been defined which allow the identification of high-velocity extraterrestrial impacts based structural morphometric parameters by surface mapping and geophysical exploration, microstructural shock metamorphic features corresponding to shock pressures >10 GPa, solid-state melting of target materials, mineralogical, geochemical ...
