Chemical Ionization Mass Spectrometry: Fundamental Principles, Diverse Applications, and the Latest Technological Frontiers

Mass Spectrometry Reviews, EarlyView.
ABSTRACT The review examines the evolution of chemical ionization mass spectrometry (CI‐MS), a technique developed in 1966 by Field and Munson. CI is a soft‐ionization method that produces more intense molecular ions with less fragmentation than electron ionization (EI).

GYPSUM KARST IN THE OLVERA AREA (CADIZ PROVINCE, ANDALUSIA, SPAIN)

, 2009
In the Olvera area (Cádiz Province, Andalusia, Spain) different karstic lithologies (preferentially carbonates and gypsum) are recognizable, relating to rainfall values of the zone and producing a karst complex of a certain interest.

An Elasto–Plastic Hydro–Mechanical Model for Analyzing the Swelling Behavior of Heterogeneous Clay–Sulfate Rocks

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Swelling of clay‐sulfate rocks is a concern in geotechnical engineering that can damage infrastructure. In the historic town of Staufen in southwest Germany, geothermal drilling into a swellable anhydrite‐bearing clay formation resulted in water inflow and subsequent swelling, triggering ground heave and damage to more than 250 houses.

CO2 and speleogenesis: suggestions from hypogene karst of Italy [PDF]

, 2015
The CO2 driving the main karst processes needs to be considerate from different sources. The carbon dioxide produced in the soil and dissolved in the percolation water is considered as the main agent for karstification in the carbonate rocks.

Needle in a haystack: Holocene history of European larch in Central Europe revisited

PLANTS, PEOPLE, PLANET, EarlyView.
Defining nativity of species is crucial for their management. However, this is a complex task, especially for species that have been used and spread by humans for a long time. We combined paleoecological records with extensive genetic data to investigate the Holocene history of European larch—a common and economically important tree species in Central ...

Using Airborne Laser Scanning and Sentinel‐2 to Understand Subcanopy Light Regimes and Understory Diversity of Vascular Plants in Temperate Mountain Forests

Remote Sensing in Ecology and Conservation, EarlyView.
This study demonstrates that not just Airborne Laser Scanning, but also Sentinel‐2 can effectively estimate absolute canopy cover and canopy cover heterogeneity ‐ structural metrics that determine the subcanopy light regime, found to be linked to the vascular plant species richness in the understory of temperate mountain forests.
