Cartographic Representation of Glacial Phenomena: Historical and Recent Developments
With the first systematic exploration of glacial phenomena in the middle of the nineteenth century, glaciology became an independent science. In parallel, glacial structures and processes needed to be visualized cartographically. Such representations always reflect the thencurrent states of the technology of glaciological data collection and of cartography. Already in the last century, well-des...
متن کاملPseudo-lesions of a Tortuous Right Coronary Artery During Percutaneous Coronary Intervention: Accordion Phenomena
Guidewire-induced pseudo-lesions are referred to accordion phenomenon and are infrequent occurrences during percutaneous coronary intervention of tortuous coronary arteries. Their occurrence can be a diagnostic challenge to the interventionist and might lead to unnecessary intervention. Ischemia and hemodynamic compromise are possible complications, if not managed promptly. The differential dia...
متن کاملThe effect of pseudo-psychic demonstrations as dependent on belief in paranormal phenomena and suggestibility
This paper describes two experiments which investigate the effects of pseudo-psychic demonstrations (i.e. conjuring tricks which could be misinterpreted as genuine paranormal phenomena). In the first study, a demonstration of a supposed medium was presented to 91 subjects individually, in which the playing card selected by a subject was identified ‘‘telepathically’’. It was found that hypnotic ...
متن کاملGlacial earthquakes.
We have detected dozens of previously unknown, moderate earthquakes beneath large glaciers. The seismic radiation from these earthquakes is depleted at high frequencies, explaining their nondetection by traditional methods. Inverse modeling of the long-period seismic waveforms from the best-recorded earthquake, in southern Alaska, shows that the seismic source is well represented by stick-slip,...
متن کاملstudy of glacial valley landform case study: sahand glacial valleys
abstract a mountain glacier, when it occupies a river valley, immediately begins to change the cross-section and profile of that valley. river valleys in mountain areas tends to have v-shaped profiles. glaciers work to widen as well as deepen their valleys and the typical cross-section of a glacial valley is u-shaped. the u-shaped glacial valley is one of the most characteristic of glacial land...
