A tephrostratigraphy of the active Antarctic volcano, Mt. Erebus, was determined from englacial tephra on the ice-covered flanks of Erebus and an adjacent volcano. The tephra are, used to reconstruct the eruptive history and magmatic evolution of Erebus. Scanning electron microscope images and Image Particle Analysis suggest the tephra formed in phreatomagmatic and magmatic eruptions and in som...

Many calderas show remarkable unrest, which often does not culminate in eruptions (non-eruptive unrest). In this context the interpretation of the geophysical data collected by the monitoring networks is difficult. When the unrest is eruptive, a vent opening process occurs, which leads to an eruption. In calderas, vent locations typically are scattered over a large area and monogenic cones form...

On Mt. Etna (Italy), an enhanced Normalized Difference in Vegetation Index (NDVI) signature was detected in the summers of 2001 and 2002 along a distinct line where, in November 2002, a flank eruption subsequently occurred. These observations suggest that pre-eruptive volcanic activity may have enhanced photosynthesis along the future eruptive fissure. If a direct relation between NDVI and futu...

A thirteen years old male patient of i was referred to our Dermatology D knees and hands. Patient was blind since birth and diagnosis of “retinitis pigmentosa” Ophthalmology Department. He was investigated and found raised levels of blood sugar, triglycerides, VLDL, TSH, SGOT/PT and kidney functions tests. He was diagnosed as a case of eruptive xanthomas with retinitis pigmentosa in secondary h...

Plasma lipoprotein alterations in nine insulin-dependent diabetics with hyperlipemia have been related to the lipid accumulating in eruptive xanthomas evolving in these patients. Histochemical and electron microscopic examination of xanthomas have been correlated with the lipid analyses in order to obtain additional evidence regarding the lipoprotein origin of lipids accumulating in the lesions...

s Caries Res 2009;43:179–244 187 with MH were prepared by sectioning and polishing. Cross-sectional Vickers hardness of the 600  m thick enamel sections was measured across MH-affected and apparently sound areas and mean hardness values analysed by one-way ANOVA. Subsequently these sections were lapped to 100 m and assessed using polarizing microscopy (PM) and transverse microradiography (TMR)...

An abstract of the thesis of Christopher Charles Humphrey for the Master of Science in Geology: presented July 2, 1996. Title: Correlation of the upper Ellensburg Formation with the Old Scab Mountain eruptive center, east-central Cascade
