Apatite Fission Track Signatures of the Ross Sea Ice Flows During the Last Glacial Maximum
Geochemistry, Geophysics, Geosystems, 2020 The catchment for the Ross Sea ice includes both the East and the West Antarctic ice sheets, but the mass balance is a direct response to climate change.

Structural derivation and crystal chemistry of apatites
, 2003 The crystal structures of the [A(1)2][A(2)3](BO4)3X apatites and the related compounds [A(1)2][A(2)3](BO5)3X and [A(1)2][A(2)3](BO3)3X are collated and reviewed.

Journal of Quaternary Science, EarlyView.Abstract Worldwide, lacustrine ecosystems are threatened by eutrophication and deoxygenation. Both processes are driven by the combined effects of human activities and climate change. Understanding the pre‐anthropogenic nexus between warming, eutrophication, deoxygenation, and related feedback is essential to determine how lakes respond to rapid ...

Synthesis and characterization of strontium–lanthanum apatites
, 2007 Two series of strontium–lanthanum apatites, Sr10−xLax(PO4)6−x(SiO4)xF2 and Sr10−xLax(PO4)6−x(SiO4)xO with 0 ≤ x ≤ 6, were synthesized by solid state reaction in the temperature range of 1200–1400 °C..

Journal of Quaternary Science, EarlyView.ABSTRACT The Fiorano quarry paleosol developed within the Colli Albani volcanic district (Italy) in the time interval bracketed by the deposition of the Pozzolanelle pyroclastic‐flow unit (365 ± 4 ka) and the emplacement of the Capo di Bove lava flow (277 ± 2 ka).

Fission fragment tracks in Apatites: recordable track lengths
, 1971 This study is concerned with the measurements of total lengths of fission fragment tracks due to spontaneous fission of 238U (fossil tracks) and neutron induced fission of 235U (π -induced tracks) in several terrestrial apatites of geological age ...

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.Abstract Purpose Introduction of new components in total knee arthroplasty (TKA) should be assessed for long‐term stability. The primary objective was to determine whether migration of a new cementless tibial baseplate in kinematically aligned (KA) TKA is below the 6‐month threshold where baseplates have a low incidence of long‐term loosening.

Crystallographic Morphology of Heterogeneous Fluoridated Carbonate Apatites
, 1993 Carbonate-containing fluoridated apatites were synthesized with two different modes of fluoride incorporation: by supplying F-free solution initially, followed by a F-containing solution; and with the order of supply of these solutions reversed. Both of

International Journal of Osteoarchaeology, EarlyView.ABSTRACT Despite the increasing number of studies undertaking isotopic analyses on archaeological material, some regions of the world and certain research foci remain underresearched and underrepresented. One of these regions is Southeast Asia, where bioarchaeological research was only comparatively recently established compared with other regions of ...
