Thermodynamically consistent model for poroelastic rocks towards tectonic and volcanic processes and earthquakes [PDF]

open access: yes, 2021
A general-purpose model combining concepts from rational continuum mechanics, fracture and damage mechanics, plasticity, and poromechanics is devised in Eulerian coordinates, involving objective time derivatives. The model complies with mass, momentum, and energy conservation as well as entropy inequality and objectivity.

An Example of Damage to Slope Stabilization Work Caused by The Frost Heaving of Mudstone and Its Countermeasure

open access: yesJournal of MMIJ, 2021
In this study,field surveys were carried out at the damaged area of slope stabilization works,where the main cause was presumed to be the frost heaving of the rock mass.Field measurements of the freezing depth and the amount of frost heave were also ...

Rocking the curve

open access: yesTrends in Microbiology, 2004
Quantifying microbial growth is of primary interest in microbiology and is routinely involved in a diversity of studies, such as comparing and/or contrasting strains and/or species, competition associated with co-infections, assessments of risks related to food contamination, testing drug efficacy, or the development of candidate vaccines [1–4].

The archaeology of rock art in Northern Africa [PDF]

open access: yes, 2017
The first reports on the rock art of north Africa were written in the mid-nineteenth century. Since then, rock art has become a key area of African archaeological research.

Projective Normality Of Algebraic Curves And Its Application To Surfaces [PDF]

open access: yes, 2006
Let $L$ be a very ample line bundle on a smooth curve $C$ of genus $g$ with $\frac{3g+3}{2}\max\{2g+2-4h^1(C,L), 2g-\frac{g-1}{6}-2h^1(C,L)\}$. Let $C$ be a triple covering of genus $p$ curve $C'$ with $C\stackrel{\phi}\to C'$ and $D$ a divisor on $C ...

Experimental study of the influence of structural planes on the mechanical properties of sandstone specimens under cyclic dynamic disturbance

open access: yesEnergy Science & Engineering, 2020
Discontinuity‐controlled slopes constitute potentially fatal risks during exploitation activities in open‐pit mines and severely threaten the safe mining of collieries. To investigate the dynamic mechanical properties of rock with structural planes under

Assessing the efficiency of thermal pressurisation using natural pseudotachylyte-bearing rocks [PDF]

open access: yesGeophys. Res. Lett. 45 (2018) 9533-9541, 2018
The efficiency of thermal pressurisation as a dynamic weakening mechanism relies on the thermal and hydraulic properties of the rocks forming the fault core. Here, we assess the effectiveness of thermal pressurisation by comparing predictions of temperature rise to field estimates based on pseudotachylyte-bearing rocks.

¿Rock and roll o rock and balls?

open access: yesClang, 2022
En este artículo se intentará abordar la problemática que implica la posición hegemónica del varónheterocis -en tanto categoría social- como referente dentro del circuito musical del rock, desde los inicios de este movimiento cultural. ¿Podríamos hablar de un escenario invisible?

Enzymatic Bioweathering and Metal Mobilization From Black Slate by the Basidiomycete Schizophyllum commune

open access: yesFrontiers in Microbiology, 2018
Schizophyllum commune is a filamentous basidiomycete causing white-rot in many wood species with the help of a broad range of enzymes including multicopper oxidases such as laccases and laccase-like oxidases. Since these enzymes exhibit a broad substrate
