MOTIVATION It has been recently suggested that atomic burials, as expressed by molecular central distances, contain sufficient information to determine the tertiary structure of small globular proteins. A possible approach to structural determination from sequence could therefore involve a sequence-to-burial intermediate prediction step whose accuracy, however, is theoretically limited by the m...
Dune plants are subjected to disturbance and environmental stresses, but little is known about the possible combined effects of such factors on growth and spatial colonization. We investigated how clones of Sporobolusvirginicus, a widespread dune species, responded to the independent and interactive effects of breakage of rhizomes, breakage position and burial regime. Horizontal rhizomes were s...
Spectroscopic evidence of the thermally induced generation of multifunctional mesoporous materials through metamorphism within the pore walls of ethenylene-bridged PMOs is presented.
This study provides forensic search teams with systematic geophysical monitoring data over simulated clandestine graves for comparison to active cases. Simulated ‘wrapped’ and ‘naked’ burials were created. Multi-geophysical surveys were collected over a three-year monitoring period. Bulk ground resistivity, Electrical Resistivity Imaging, multi-frequency Ground Penetrating Radar and grave ‘soil...
Amphibolites are one of the major rock units in the Posht-e-Badam ophiolite that are formed by metamorphism of basalts. There are tow types of amphibolite in the Posht -e- Badam ophiolite: 1) amphibolites with intermediate plagioclase (first type), amphibole, plagioclase, quartz, sphene, ilmenite, apatite, sericite and epidote, 2) amphibolites with high content of anorthite (second type), amphi...
The main objective of this effort has been the direct observation and monitoring of the burial process of finite-length cylinders (model mines) induced by the combined action of waves, currents and pure oscillatory flows. The experimental conditions have made it possible to observe the burial process due to both local scour around the mines as well as the passage of large sandwaves. These rathe...
Metamorphism along the southern margin of the Archean Superior Province has been historically attributed to the Penokean orogeny. A narrow corridor of amphibolite facies rocks north of the main suture does record 1.83–1.80 Ga metamorphic monazite U–Th–Pb ages that mark the culmination of arc accretion. However, subsequent widespread amphibolite facies metamorphism and associated magmatism is re...
