NATURAL-TECHNOLOGICAL DISASTERS AS MANIFESTATIONS OF GEODYNAMIC INSTABILITY OF THE EARTH'S CRUST
Известия Томского политехнического университета: Инжиниринг георесурсов, 2019 The relevance. Geodynamic instability is the cause of many natural disasters: earthquakes, volcanic eruptions, landslides, tsunamis. Natural disasters can trigger man-made accidents (collapse of buildings and structures, explosions in mines, dam ...

Indian Journal of Dermatology, Venereology and Leprology, 2009 Crusted scabies is a rare manifestation of scabies characterized by uncontrolled proliferation of mites in the skin. In immunocompromised patients, this infestation is characterized by crusted lesions. The occurrence of the disease in human immunodeficiency virus-infected patients and the widespread use of immunosuppressive agents has led to a renewed ...

Transformation of a Silicate Material for Carbon Negative Magnesia‐Based Cement via Electrochemistry
Advanced Science, EarlyView.The transformation of a magnesium trisilicate material via water electrolysis into precursor phases necessary for magnesium‐based M‐S‐H cement is explored. The dissolution of the material mediated electrochemically is monitored, and the analysis of the resulting phases indicate their suitability as effective precursors for M‐S‐H cement.

Granitic rocks and metasediments in Archean crust, Rainy Lake area, Ontario: ND isotope evidence for mantle-like SM/ND sources [PDF]
Granitoids, felsic volcanic rocks and clastic metasediments are typical rocks in Archean granite-greenstone belts that could have formed from preexisting continentasl crust.

Advanced Science, EarlyView.This study primarily reveals that PM2.5‐derived Fe‐containing particles, particularly magnetite, are specifically enriched in the heart. Here, they interact with NCOA4 in endothelial cells, disrupt iron homeostasis by enhancing ferritinophagy, and subsequently trigger the process of EndMT through the NCOA4/KLF5 pathway.

Continental crustal composition and lower crustal models [PDF]
The composition of the upper crust is well established as being close to that of granodiorite. The upper crustal composition is reflected in the uniform REE abundances in shales which represent an homogenization of the various REE patterns.
