Magnetic storms during the space age: Occurrence and relation to varying solar activity [PDF]

J. Geophys. Res.: Space, 127, e2022JA030830, 2022
We study the occurrence of magnetic storms in space age (1957-2021) using Dst and Dxt indices. We find 2526/2743 magnetic storms in the Dxt/Dst index, out of which 45% are weak, 40% moderate, 12% intense and 3% major storms. Occurrence of storms in space age follows the slow decrease of sunspot activity and the related change in solar magnetic ...

Cyclones, tides, and the origin of a cross-equatorial dust storm on Mars [PDF]

, 2003
We investigate the triggering mechanism of a cross-equatorial dust storm observed by Mars Global Surveyor in 1999. This storm, which had a significant impact on global mean temperatures, was seen in visible and infrared data to commence with the ...

Time Series of Remote Sensing Data for Interaction Analysis of the Vegetation Coverage and Dust Activity in the Middle East

Remote Sensing, 2022
Motivated by the lack of research on land cover and dust activity in the Middle East, this study seeks to increase the understanding of the sensitivity of dust centers to climatic and surface conditions in this specific region. In this regard, we explore

Method development for quantitative monitoring of monoclonal antibodies in upstream cell‐culture process samples with limited sample preparation – An evaluation of various capillary coatings

ELECTROPHORESIS, Volume 44, Issue 1-2, Page 96-106, January 2023., 2023
Abstract Monoclonal antibodies (mAbs) have become an important class of biopharmaceuticals used for the treatment of various diseases. Their quantification during the manufacturing process is important. In this work, a capillary zone electrophoresis (CZE) method was developed for the monitoring of the mAb concentration during cell‐culture processes ...

Source areas of the Eastern Ebro Valley loess (NE Iberian Peninsula): Heavy mineral composition as a provenance indicator

Earth Surface Processes and Landforms, Volume 47, Issue 15, Page 3611-3628, December 2022., 2022
The loess provenance areas of the Ebro and Móra basins are mainly the fluvial terraces of the Middle and Lower Ebro River, respectively, according to the analyses of very heavy minerals and particle size. The wind transport distances are relatively short (<100 km).
