The Material Basis of 18th‐Century Meissen Porcelain

Archaeometry, EarlyView.
ABSTRACT In the summer of 1708, the quest for making hard‐paste porcelain from Saxonian clay and other mineral resources succeeded. This was achieved by applying as its essential ingredient newly discovered pure kaolin from Heidelsberg near Aue, western Saxon Ore Mountains.

P–T Modelling Constrains the Depth of Emplacement of the Porto Azzurro Pluton and Implies Minor Exhumation Caused by the Zuccale Fault (Island of Elba, Italy)

Journal of Metamorphic Geology, EarlyView.
ABSTRACT Understanding the pressure of emplacement of granitic intrusions is crucial to understanding the exhumation history of plutons and constraining the tectonic setting of magma emplacement. However, P–T and geochronological constraints from exhumed plutons are often characterized by large uncertainties, especially in shallow crustal settings with

Adjustment errors of sunstones in the first step of sky-polarimetric Viking navigation: studies with dichroic cordierite/ tourmaline and birefringent calcite crystals [PDF]

Royal Society Open Science, 2016
According to an old but still unproven theory, Viking navigators analysed the skylight polarization with dichroic cordierite or tourmaline, or birefringent calcite sunstones in cloudy/foggy weather.

Araguainha Dome, Brazil: A polygonal impact structure due to a complex pre‐impact regional structural framework

Meteoritics &Planetary Science, EarlyView.
Abstract We investigated the structural framework of the north–northwestern Paraná Basin in Brazil to test whether the pre‐impact structures in this region may have had any influence on the first‐order formation and morphostructure of the Araguainha impact structure (AIS).

Emergence of Continents Stabilized the Bioavailability of Boron

Terra Nova, EarlyView.
ABSTRACT Boron is an essential element for the development of life on Earth; borates stabilize ribose in prebiotic reactions and facilitate metabolism in higher plants. There is, however, a relatively narrow surface boron concentration range over which borates stabilize and serve as a micronutrient rather than a toxin.

Tourmaline and tourmaline schists from Belcher hill, Colorado [PDF]

Geological Society of America Bulletin, 1899
Introduction Tourmaline is a not uncommon mineral in the northern part of Jefferson county, Colorado. It is to be found as an ingredient of the quartz-feldspar boulders which strew the mesas bordering the foothills west of Denver and in the beds of the streams which drain the crystalline schists of these foothills. It may also be found in place in the

Effects of Dapagliflozin on Cardiovascular Outcomes in Patients With Type 2 Diabetes at Risk of Liver Fibrosis

Diabetes, Obesity and Metabolism, Volume 28, Issue 7, Page 6142-6150, July 2026.
ABSTRACT Aims The fibrosis‐4 (FIB‐4) score is used to identify risk of advanced liver fibrosis. This post hoc analysis investigated its prognostic value for cardiovascular (CV) outcomes and its relevance to the effects of dapagliflozin. Materials and Methods DECLARE‐TIMI 58 was a randomised, placebo‐controlled phase 3 trial investigating dapagliflozin ...
