GEOMAGNETIC EXCURSION RECORD PRESERVED IN THE SPELEOTHEM FROM WESTERN CAUCASUS: FIRST DATA

Геодинамика и тектонофизика, 2022
The study of the geomagnetic field evolution on minor timescales, in particular of such significant events as geomagnetic reversals and excursions, has acquired particular relevance nowadays due to the increased attention of mankind to the environment ...

Oxidative Heck desymmetrisation of 2,2-disubstituted cyclopentene-1,3-diones [PDF]

, 2015
Oxidative Heck couplings have been successfully developed for 2,2-disubstituted cyclopentene-1,3-diones. The direct coupling onto the 2,2-disubstituted cyclopentene-1,3-dione core provides a novel expedient way of enantioselectively desymmetrising all ...

Highly-crystallized quaternary chalcopyrite nanocrystals via a high-temperature dissolution–reprecipitation route [PDF]

, 2011
Quaternary chalcopyrite (Cu2CoSnS4, Cu2ZnSnS4) nanocrystals displaying high crystallization and controlled morphology were synthesized via a high-temperature growth regime achieved by dissolution–reprecipitation of tailored ultrafine precursors in the ...

Quaternary glacial cycles: Karst processes and the global CO2 budget

Acta Carsologica, 2013
Extensive research has been conducted investigating the relationship between karst processes, carbonate deposition and the global carbon cycle. However, little work has been done looking into the relationship between glaciations, subsequent sea level ...

More water-soluble brown carbon after the residential “coal-to-gas” conversion measure in urban Beijing

npj Climate and Atmospheric Science, 2023
The implementation of air pollution reduction measures has significantly reduced the concentration of atmospheric fine particles (PM2.5) in Beijing, among which the “coal-to-gas” conversion measures may play a crucial role.

High-resolution remapping of the coastal dune fields of south east Queensland, Australia: a morphometric approach

Journal of Maps, 2019
The sand islands and shore-attached dune fields of south east Queensland form the world’s oldest and largest coastal sand dune system. Here we present updated morphological maps for the dune fields based on topographic expression and geomorphic ...

Morphostratigraphy of the Sázava river terraces in the Bohemian Massif

Acta Universitatis Carolinae Geographica, 2021
The results of geomorphological research into the Sazava river terraces are presented. This terrace system is characteristic by its variable structure which is conditioned by specific hydrodynamic processes that existed during the late Cenozoic evolution

Personalized Selumetinib Dosing in Pediatric Neurofibromatosis Type 1: Insights From a Pilot Therapeutic Drug Monitoring Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Objective To evaluate selumetinib exposure using therapeutic drug monitoring (TDM) in pediatric patients with neurofibromatosis type 1 (NF1) and plexiform neurofibromas (PN), assess interpatient pharmacokinetic variability, and explore the relationship between drug exposure, clinical response, and adverse effects.
