Assessing the Reliability of the Pseudo‐Thellier Estimates in Fired Ceramics and Source Clays
Journal of Geophysical Research: Solid Earth, Volume 130, Issue 7, July 2025.Abstract The geomagnetic field's intensity is key to understanding the Earth's core dynamics and their surface impacts. While the Thellier–Thellier method remains the standard for recovering absolute paleointensity from baked materials, it is time‐consuming and may alter magnetic mineralogy due to heating cycles. The pseudo‐Thellier method offers a non‐

Mixing of Two Microbial Consortia in the Search for Stimulating Chromium Depletion
International Journal of Microbiology, Volume 2025, Issue 1, 2025.Two bacterial consortia (C55 and C33), obtained from an industrial residue contaminated with hexavalent chromium (Cr(VI)), were used to study the behavior of their mixture for depleting this ion in liquid media. In the absence of Cr(VI), C55 showed a greater growth rate than C33, while the latter exhibited biofilm formation. In the presence of this ion,

Effect of CuO Nanoparticles over Isolated Bacterial Strains from Agricultural Soil
Journal of Nanomaterials, Volume 2014, Issue 1, 2014., 2014 The increased use of the nanoparticles (NPs) on several processes is notorious. In contrast the ecotoxicological effects of NPs have been scarcely studied. The main current researches are related to the oxide metallic NPs. In the present work, fifty‐six bacterial strains were isolated from soil, comprising 17 different OTUs distributed into 3 classes ...
