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

open access: yesBiological 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

An acrocarpous moss in Cretaceous amber from Myanmar

open access: yes, 2014
Recent studies have indicated considerable changes in the lineage composition of mosses during the Cretaceous terrestrial revolution. However, Cretaceous moss fossils are generally rare.

Geochronological and structural constraints on the Cretaceous thermotectonic evolution of the Kraishte zone (Western Bulgaria) [PDF]

open access: yes, 2010
In the Kraishte region, near the junction of the Balkanides and Dinarides, late Early Cretaceous compression led to the thrusting of the Morava unit over the Struma unit.

Clathrate hydrate crystallization

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Clathrate hydrate crystallization has been an area of interest to chemical engineers from the point of view of crystal structure, thermophysical properties, phase equilibria, kinetics, industrial applications, and environmental (climate change) implications.

British Cretaceous Nuculidæ [PDF]

open access: yesQuarterly Journal of the Geological Society of London, 1884
T he Nuculæ and Ledæ with their allies, are now generally separated from the Arcidæ, and in a palæontological point of view this separation is amply justified; for their distinctive characters have persisted throughout many geological periods, and may be recognized to some extent ...

Gladiopycnodontidae, a new family of pycnodontiform fi shes from the Late Cretaceous of Lebanon, with the description of three genera [PDF]

open access: yes, 2013
The osteology of Gladiopycnodus karami gen. et sp. nov., of Monocerichthys scheuchzeri gen. et sp. nov. and of Rostropycnodus gayeti gen. et sp. nov., three new fossil fishes from the marine Cenomanian (Late Cretaceous) of Lebanon, is studied in detail ...

Slip versus dilation tendency parameter space as a tool for prospecting structurally controlled geothermal systems in greenfield: insights from the greater Ruhr region

open access: yesDeep Underground Science and Engineering, EarlyView.
This study highlights that with the static and time‐dependent evolution of slip versus dilation tendency parameter space, structurally controlled deep geothermal systems can be selected within areas of higher permeability and lower seismic hazard. Abstract Faults play a vital role in the Earth's hydraulic system by facilitating fluid flow when dilating

Semi‐analytical solution for the stability of deep vertical shaft considering time‐dependent rock‐structure interaction

open access: yesDeep Underground Science and Engineering, EarlyView.
A novel cavity contraction solution and multilayer shaft wall model were developed to analyze deep shaft stability, considering rock viscosity, support structures, and water pressure, with successful validation through a Hulusu Coal Mine case study.

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

open access: yesDeep 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

Petroleum bearing potential of the northwestern part of the Chardzhou Step and future prospects [PDF]

open access: yesНефтегазовая геология: Теория и практика
This paper examines the petroleum bearing potential of the northwestern Chardzhou Step of the Bukhara-Khiva region of the Republic of Uzbekistan, encompassing the Gugurtli-Uchkyr and Kandym uplifts, and the opportunity for expanding the hydrocarbon ...
