This study constitutes one of the few works conducted on the colonization of recent lava flows by fish communities in coral reef environment. It attempted to describe themechanisms of colonization and environmental variables influencing the structure of communities on the lava flows of the Piton de la Fournaise volcano at Reunion Island. It also proposed somehypotheses on themechanisms of selec...

Rocks around the InSight lander were measured in orthoimages of near field (<10 m), panoramas far (<40 and a high-resolution orbital image (1 km2). The cumulative fractional area versus diameter size-frequency distributions for four areas fall on exponential model curves used estimating hazards landing spacecraft. rock abundance varies from 0.6% sand pebble-rich to east within Homestead hollow ...

Cardiac arrhythmias are heart rhythm disruptions which can lead to sudden cardiac death. They require a deeper understanding for appropriate treatment planning. In this thesis, we integrate personalized structural and functional data into a 3D tetrahedral mesh of the biventricular myocardium. Next, the Mitchell-Schaeffer (MS) simplified biophysical model is used to study the spatial heterogenei...

Pele has been the most intense high-temperature hotspot on Io to be continuously active during the Galileo monitoring from 1996–2001. A suite of characteristics suggests that Pele is an active lava lake inside a volcanic depression. In 2000–2001, Pele was observed by two spacecraft, Cassini and Galileo. The Cassini observations revealed that Pele is variable in activity over timescales of minut...

PURPOSE To investigate the microtensile bond strength between two all-ceramic systems; lithium disilicate glass ceramic and zirconia core ceramics bonded with their corresponding glass veneers. MATERIALS AND METHODS Blocks of core ceramics (IPS e.max® Press and Lava™ Frame) were fabricated and veneered with their corresponding glass veneers. The bilayered blocks were cut into microbars; 8 mm ...

Abstract Indonesia’s archipelago formed by the tectonic evolution proceeded with subduction, which was accompanied volcanism. The systematic subduction zones produce magmatic arcs different periods since Permian up to Tertiary. However, only recent Quaternary volcanic arc is recognized and lacked of information about ancient environment. Calderas are a crucial feature in any environment due pro...

Animating lava flowing down the slopes of a volcano brings several challenges: modeling the mechanical features of lava and how they evolve over time depending on temperature; computing, in a reasonable time, the interactions inside the flow, and between the flow and a complex terrain data-base; and lastly, rendering the visual aspect of the flow. The methods described rely on smoothed particle...

[1] One process for the formation of continental crust is the accretion of arc terranes at continental margins. A longstanding problem with this model is that although the composition of the continental crust is andesitic, the majority of arc lavas are basaltic. Moreover, those arc lavas that are andesitic tend to be evolved (lower Mg #) compared to the continental crust. Continental crust can ...

Late Ediacaran rocks of the Ouarzazate Group define a thin pile sediments and pyroclastic deposits between Paleoproterozoic basement Cambrian sedimentary cover in southern Kerdous Tagragra d’Akka inliers. In Tafeltast area, terrigenous with volcano-sedimentary are located grabens controlled by syn-sedimentary normal faults. The sedimentation is characterized maximum flooding outlined Agoujgal c...

High concentrations of acid were found to arise from the interaction between molten rock and seawater at the shoreline of Kilauea Volcano, Hawaii. A series of field samplings and experiments show that the acid was derived from two sources: the release of magmatic volatiles and water–rock reactions. Although the bulk of the magmatic volatiles (CO2, H2O, and SO2) are vented at Puu Oo cinder cone ...
