Winter Baseflow Calibration's Critical Role in Hydrological Modeling for the Pamir Region

Water Resources Research, Volume 62, Issue 1, January 2026.
Abstract The Pamir Mountains, a critical water source for Central Asia, require accurate quantification of runoff components for water resource management under climate change. Uncertainties in precipitation data are known to greatly affect hydrological model accuracy, leading to the widespread use of multi‐data calibration methods to avoid internal ...

Síntese por reação por combustão de nanopós de hexaferrita de estrôncio dopada com cromo

Cerâmica, 2014
Nanopós de hexaferrita de estrôncio dopadas com cromo foram sintetizadas por reação por combustão. A influência do Cr3+ nas proporções de x = 0, 0,2, 0,3 e 0,4 no sistema SrCr xFe12-xO19 foi investigada.

Magnetic and Paleomagnetic Characterization of the Ivrea‐Verbano Lower Crust Body (NW Italy): Assessing the Magnetization of Variscan‐Age Lower Crust

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 6, June 2025.
Abstract The source of high‐intensity magnetic anomalies from (mostly Precambrian) lower crust of continent interiors has long been debated, as it requires speculative rocks yielding 2–6 A/m magnetization. We report on the magnetic and paleomagnetic investigation of the Ivrea‐Verbano Zone (IVZ), Western Alps, where metamorphic and intrusive lower crust

Acceleration of Abramov Glacier (Pamir‐Alay) retreat since the Little Ice Age

Boreas, Volume 53, Issue 3, Page 415-429, July 2024.
The Abramov Glacier, situated in the Koksu River valley in the Pamir‐Alay Mountain range, was extensively monitored from 1965 to 1999 and again since 2011, providing valuable climate data. We apply cosmogenic 10Be exposure datings, ground penetrating radar measurements combined with numerical modelling as well as calculation of secular glacier mass ...

Plant‐based meat analogues marketed in Catalonia: analysis of contaminants, essential elements, microbiological and physicochemical status, dietary intake estimation and health risk assessment

Food Risk Assess Europe, Volume 2, Issue 3, July 2024.
Abstract The latest barometer of food safety in Catalonia conducted by the Catalan Food Safety Agency (ACSA for its initials in Catalan) in 2021 shows that 28.7% of the population consumes meat analogues (substitutes). The main reasons for consuming this type of food are animal welfare, followed by environmental and health reasons.

Molecular testing in salivary gland cytopathology: A practical overview in conjunction with the Milan system

Cytopathology, Volume 35, Issue 3, Page 330-343, May 2024.
Significant advances have been made in the molecular characterization of salivary gland neoplasms. In this scenario, molecular testing may be adopted to refine cytological diagnosis, in particular in challenging cases. Over the past decades, molecular characterization of salivary gland neoplasms has significantly improved. In this setting, the adoption
