The Dynamics of Lava Flows

open access: yesAnnual Review of Fluid Mechanics, 2000
Lava flows are gravity currents of partially molten rock that cool as they flow, in some cases melting the surface over which they flow but in all cases gradually solidifying until they come to rest. They present a wide range of flow regimes from turbulent channel flows at moderate Reynolds numbers to extremely viscous or plastic, creeping flows, and ...

“Cold Tropics”: Permafrost Existence and Thickness on Eastern Nevado Coropuna (Southern Peruvian Andes) Revealed by Ground‐Penetrating Radar and Geoelectrical Soundings

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT The existence of permafrost was explored at tropical latitude on Nevado Coropuna (southern Peruvian Andes) using a combination of ground‐penetrating radar (GPR) and vertical electrical sounding (VES) in order to strengthen the mutual validation of data processing and interpretation.

Building capacity in vector‐borne plant virus research: The CONNECTED Network

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Plant viruses spread by insects decimate crop yields globally, causing food security challenges in vulnerable areas, including regions of Africa. Interdisciplinary research is needed to protect future crop supplies. CONNECTED, the Community Network for African Vector‐Borne Plant Viruses, increased research capacity in Central, East, West and Southern ...

Identification of structural controls in an active lava dome with high resolution DEMs : Volcán de Colima, Mexico [PDF]

open access: yes, 2012
Monitoring the topography of active lava domes is critical for detecting changes that may trigger or influence collapse or explosive activity. Internal dome structure and conditions are more difficult to elucidate, but also play vital roles.

jonaskat87/lava-solidification: Second release

open access: yes, 2021
The first submitted draft of "Some lava flows may not have been as thick as they appear" was sent back for major revisions. One such revision we made was adding a new set of simulations in which we compared our model with data from Hon et al. (1994) v1.0.

Model‐Based Systems Engineering in Space Applications: A Comprehensive Literature Review

open access: yesSystems Engineering, EarlyView.
ABSTRACT The growing complexity of space engineering is driving the demand to embrace the adoption of Model‐Based Systems Engineering (MBSE). Although the MBSE is well‐practiced in the space industry, the level of effort and need required to obtain the benefits of MBSE vastly differ across enterprises; this disparity presents a significant challenge to

Viscoelastic behaviour of basaltic lavas. [PDF]

open access: yes, 2004
The rheological properties of basaltic lavas from Etna, Hawai′i and Vesuvius have been investigated at temperatures between 500 and 1150°C using a small-strain oscillatory shear. The viscoelastic response of the lavas to small, forced, sinusoidal torques

Making Mining Licit: Gold, Commodification, and the Everyday Performance of Law in Colombia

open access: yesAmerican Anthropologist, EarlyView.
ABSTRACT Ethnographies of resource‐making have shown that the extraction of resource value from objects is premised on obviating the emplaced lifeworlds that surrounded objects before they traveled to consumer markets. Much of this literature looks at such supply‐chain disentanglement from the viewpoint of corporate and formal regulatory practices ...

The emplacement of an obsidian dyke through thin ice : Hrafntinnuhryggur, Krafla Iceland. [PDF]

open access: yes, 2009
An eruption along a 2.5 km-long rhyolitic dyke at Krafla volcano, northern Iceland during the last glacial period formed a ridge of obsidian (Hrafntinnuhryggur).
