Seeking a geochemical identifier for authigenic carbonate
Nature Communications, 2016 Distinguishing between authigenic carbonate and primary marine carbonate is fundamental to our understanding of Earth’s carbon, oxygen and calcium cycles.

Formation and evolution of a metasomatized lithospheric root at the motionless Antarctic plate: the case of East Island, Crozet Archipelago (Indian Ocean) [PDF]
, 2016 Sitting atop the nearly stagnant Antarctic plate (ca. 6.46 mm/yr), the Crozet archipelago midway between Madagascar and Antarctica constitutes a region of unusually shallow (1543-1756 m below sea level) and thickened oceanic crust (10-16.5 km), high ...

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Coal pyrolysis, as a key thermochemical conversion process, is significantly influenced by inherent minerals, yet their role across different coal ranks remains inadequately understood. This study investigates the effect of acid‐washing (demineralization) on the thermal decomposition of six functional groups (aliphatic C–H, aromatic C–H/C=C, C=

Blood Reviews, 1994 The term mantle cell lymphoma (MCL) has been introduced recently, to describe lymphomas related to the primary B follicle and the mantle of the secondary lymphoid follicle. MCL forms a subset of diffuse small cleaved cell lymphomas according to the Working Formulation and correspond closely to the centrocytic lymphomas described in the Kiel ...

Three‐dimensional flow in the subslab mantle
Geochemistry, Geophysics, Geosystems, 2014 Three‐dimensional models of mantle flow at subduction zones make it possible to explain the common occurrence of trench‐parallel subslab seismic anisotropy.

Mantle transect of the Karelian Craton from margin to core based on P-T data from garnet and clinopyroxene xenocrysts in kimberlites [PDF]
Bulletin of the Geological Society of Finland, 2009 Peridotitic garnet and clinopyroxene xenocrysts from the 1.2 Ga Lentiira-Kuhmo and the 760 Ma Kuusamo kimberlite fields, emplaced within the Central Karelian Craton, have been studied using major and trace element geochemistry to obtain information on ...

Archaeological Prospection, EarlyView.ABSTRACT Neolithic long barrows are among the earliest monumental structures in Europe, yet in many parts of Central Europe their surface expression has been largely erased by long‐term agricultural activity. This study evaluates the potential of integrated remote sensing approaches for identifying and contextualizing long barrows and associated ...

Frontiers in Marine Science, 2019 The proteins derived from the foliated shell layer of the oyster, Crassostrea virginica, are unusually acidic and highly phosphorylated. Here we report the identification of a gene encoding a member of this class of phosphoproteins that we collectively ...

Nature, 2001 Seismological images of the Earth's mantle reveal three distinct changes in velocity structure, at depths of 410, 660 and 2,700 km. The first two are best explained by mineral phase transformations, whereas the third-the D" layer-probably reflects a change in chemical composition and thermal structure.

British Journal of Clinical Pharmacology, EarlyView.Aims This study looks at the status of the same drugs conditionally approved by the Food and Drug Administration and Health Canada for the same oncology indication. Methods Lists of oncology drugs with a conditional approval from the Food and Drug Administration and Health Canada were generated and drug pairs with the same indication were matched ...
