Hot and cold deserts as eco‐evolutionary arenas for understanding plant resistance to multiple abiotic stressors

Biological Reviews, EarlyView.
ABSTRACT During their long evolutionary history, land plants have evolved a range of adaptations to different abiotic stressors. These help explain present‐day diversity and distribution patterns, as well as the potential resilience of natural and agricultural systems to a changing climate. Most previous research has focused on adaptation to individual

Lower and Middle Jurassic organic-rich rocks of W and SW Ukraine, NE Romania and S Moldova: occurrence, hydrocarbon generation zones and mineralogy [PDF]

Estonian Journal of Earth Sciences
The organic-rich strata of the Lower and Middle Jurassic occur within separate blocks, covering significant areas of the Carpathian Foredeep basement, the Bârlad Depression and the Dobrogean Foredeep.

Pangean (Late Carboniferous–Middle Jurassic) paleoenvironment and lithofacies

Palaeogeography, Palaeoclimatology, Palaeoecology, 2000
Abstract Six time interval maps were constructed that depict the plate tectonic configuration, paleogeography and lithofacies for Pangea from the Late Carboniferous through the Middle Jurassic. Generally, the individual maps illustrate the conditions present during the maximum marine transgressions of higher frequency cyclicity within the Absaroka ...

Reflux stratabound dolostone and hydrothermal volcanism- associated dolostone: a two-stage dolomitization model (Jurassic, Lebanon) [PDF]

, 2004
The Kesrouane Formation, which is characterized by pervasive dolomitization, has a stratigraphic thickness that exceeds 1000 m. It is part of a broad carbonate platform deposited in the Levant region and represents 60% of the Lebanese Jurassic rocks. Two

‘What is the project?’: A fine‐grained study of some key challenges to interdisciplinary teaching and learning in the humanities

The Curriculum Journal, EarlyView.
AbstractInterdisciplinary teaching and learning in the humanities (Humanities ITL) has gained prominence in recent decades. Yet to date, empirical research has largely emphasised its benefits and affordances, with far fewer studies examining the challenges it poses.

Fracture evolution of a thick soft protection layer and the water inrush mechanism in overburden under longwall mining

Deep Underground Science and Engineering, EarlyView.
Through shear–tensile creep tests and viscoelastic modeling, the fracture evolution of thick soft protective layers is clarified. Results show thickness‐dependent rheological failure modes that govern four types of roof water inrush, providing a mechanism‐based framework for hazard prediction and control. Abstract In the Jurassic coal‐bearing strata of

The palaeoecology of two Scottish encrinites: Jurassic crinoid assemblages from the Trotternish Peninsula, Isle of Skye, Scotland [PDF]

, 2009
Despite a long history of investigation, articulate crinoids from the Jurassic of Scotland have not received great attention compared to their counterparts in Southern England or continental Europe; this is thought to be largely due to poor preservation.

Numerical Simulation Study on Optimization of Horizontal Sublevel Top‐Coal Caving Mining Technique for Steeply Inclined Extra‐Thick Coal Seam

Energy Science &Engineering, EarlyView.
As the sublevel height increases, the top‐coal recovery amount gradually increases, but both the top‐coal recovery rate and the thickened top‐coal recovery rate show a downward trend, and the decline in the top‐coal recovery rate is gradually increasing. The comparison indicates that the optimal sublevel height is 20 m.

Fracture Development Mechanism of Water‐Isolating Soil Layers During Downward Mining of Shallow‐Buried Coal Seam Groups

Energy Science &Engineering, EarlyView.
This study systematically investigates the fracture development mechanisms of water‐isolating soil layers under the coupled effects of repeated mining and groundwater seepage during the downward mining of shallow‐buried coal seams. The findings provide a theoretical basis for evaluating stratum stability and preventing roof water inrush.

STRATIGRAFIA DEL GIURASSICO DEI DINTORNI DI FOZA (ALTOPIANO DI ASIAGO)

Rivista Italiana di Paleontologia e Stratigrafia, 2023
The Middle and Upper Jurassic sequence near Foza (Asiago plateau; Venetian Alps) is characterized by important hiatuses. The relevant deposits are furthermore often found as sedimentary dikes, filling up fractures in the underlying carbonatic platform ...
