Triggering Collapse of the Presolar Dense Cloud Core and Injecting Short-Lived Radioisotopes with a Shock Wave. IV. Effects of Rotational Axis Orientation

, 2015
Both astronomical observations of the interaction of Type II supernova remnants (SNR) with dense interstellar clouds as well as cosmochemical studies of the abundances of daughter products of short-lived radioisotopes (SLRIs) formed by supernova ...

Potential of Soils Natural Sorbents for Environmental Decontamination From 137Cs

Land Degradation &Development, EarlyView.
ABSTRACT This study addresses the existing research gap concerning the lack of integrated data on the role of in situ soil components in the long‐term fixation of 137Cs under natural, protected, and non‐agricultural conditions. The contamination of ecosystems by radioactive isotopes, particularly 137Cs, represents a considerable environmental hazard ...

Novel method for determining of 137Cs in seawater using liquid scintillation counter

Limnology and Oceanography: Methods, EarlyView.
Abstract Robust and efficient monitoring of radiocesium in the marine environment has become increasingly important, especially following the Fukushima Daiichi Nuclear Power Plant accident. A liquid scintillation counter (LSC) has been used for 137Cs analysis—which was identified as one of the hazardous radionuclides; however, a major limitation of ...

Motor and Cognitive Outcome After Subthalamic Nucleus Deep Brain Stimulation in Patients with Parkinson's Disease Harboring GBA1 Variant

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Deep brain stimulation (DBS) is effective for Parkinson's disease (PD); however, its efficacy varies with genetic background, such as the GBA1 variant—the causative gene of Gaucher disease—associated with increased PD risk and cognitive decline after subthalamic nucleus (STN)‐DBS.
