Caribbean Plate margin evolution : constraints and current problems [PDF]

open access: yes, 2006
Oceanic crust was generated at multiple spreading centres during the Jurassic and Early Cretaceous, forming a "proto-Caribbean" oceanic domain. During the Cretaceous, part of that crustal domain thickened into an oceanic plateau, of petrologic Mid-Ocean ...

Reflexive thematic analysis and men's embodiment following injury or illness: A worked example

open access: yesAnatomical Sciences Education, EarlyView.
Abstract Reflexive thematic analysis (reflexive TA) originated within psychology and the social sciences and has become an increasingly popular qualitative analytic method across a range of disciplines. In this article, we offer a brief methodological guide for researchers hoping to use the method, suitable for beginners through to those experienced in

A uniform isotopic and chemical signature of dust exported from Patagonia: Rock sources and occurrence in southern environments [PDF]

open access: yes, 2007
Patagonia is considered to be the most important source of dust from South America that is deposited in surrounding areas, and we present here a systematic Sr and Nd isotopic study of sediment currently being exported.

Investigation of Electrolyte Salts in Non‐Flammable Triethyl Phosphate for Sodium‐Ion Batteries

open access: yesBatteries &Supercaps, Volume 8, Issue 3, March 2025.
This study evaluates five sodium electrolyte salts (NaBF₄, NaClO₄, NaDFOB, NaFSI, NaPF₆) in triethyl phosphate (TEP) for sodium‐ion full‐cells, focusing on their physicochemical properties, solvation structure, and electrochemical performance. The addition of 1 wt.% vinylene carbonate (VC) improves cycling performance, with NaFSI demonstrating 88 ...

Why we age

open access: yesBiological Reviews, EarlyView.
ABSTRACT Three categories of explanations exist for why we age: mechanistic theories, which omit reference to evolutionary forces; weakening force of selection theories, which posit that barriers exist that prevent evolutionary forces from optimising fitness in ageing; and optimisation theories, which posit that evolutionary forces actually select for ...

A latest Cretaceous to earliest Paleogene dinoflagellate cyst zonation of Antarctica, and implications for phytoprovincialism in the high southern latitudes [PDF]

open access: yes, 2012
The thickest uppermost Cretaceous to lowermost Paleogene (Maastrichtian to Danian) sedimentary succession in the world is exposed on southern Seymour Island (65° South) in the James Ross Basin, Antarctic Peninsula.

The impacts of biological invasions

open access: yesBiological Reviews, EarlyView.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Shoshonitic enclaves in the high Sr/Y Nyemo pluton, southern Tibet: Implications for Oligocene magma mixing and the onset of extension of the southern Lhasa terrane [PDF]

open access: yes, 2020
Post-collisional potassic and high Sr/Y magmatism in the Lhasa terrane provides critical constraints on the timing and mechanism of subduction of Indian lithosphere and its role in the uplift of the Tibetan Plateau.

Response and Recovery of the Comanche Carbonate Platform Surrounding Multiple Cretaceous Oceanic Anoxic Events, Northern Gulf of Mexico [PDF]

open access: yes, 2015
The ubiquity of carbonate platforms throughout the Cretaceous Period is recognized as a product of high eustatic sea-level and a distinct climatic optimum induced by rapid sea-floor spreading and elevated levels of atmospheric carbon-dioxide.
