Integrated geophysical‐petrological modeling of lithosphere‐asthenosphere boundary in central Tibet using electromagnetic and seismic data

Geochemistry, Geophysics, Geosystems, 2014
We undertake a petrologically driven approach to jointly model magnetotelluric (MT) and seismic surface wave dispersion (SW) data from central Tibet, constrained by topographic height. The approach derives realistic temperature and pressure distributions

A high‐energy X‐ray beamline for materials science research at SPring‐8: BL15XU

Journal of Synchrotron Radiation, EarlyView.
The Japanese synchrotron facility SPring‐8 has recently relaunched BL15XU as a high‐energy X‐ray beamline for materials science research. A comprehensive description of the technical details and science cases is presented.The high‐energy X‐ray beamline BL15XU is designed to drive advancements in materials science and high‐pressure research by ...

PGM in chromitites of Kraka massifs (the Southern Urals): diversity and origin

Georesursy
The paper provides results of study of platinum group minerals (PGMs) from 18 ore occurrences and deposits of the Kraka massifs, most of these located in ultramafic rocks of the upper mantle section (15), and several occurrences in a crust-mantle ...

On Convection in the Upper Mantle [PDF]

Geophysical Journal of the Royal Astronomical Society, 2010
Summary Present estimates of viscosity and other pertinent parameters make it unlikely that thermal convection exists in the lower mantle. Convection may be considered from the point of view of an instability process for the upper mantle but the probable non-Newtonian nature of viscosity in the upper mantle makes this problem difficult to solve.

Remembering Interracial Intimacies: South Asian Perspectives on Black/Brown Sex and Romance in Colonial East Africa

Gender &History, EarlyView.
ABSTRACT Bringing together historical evidence, postcolonial fiction and memory work, this study recovers South Asian cultural attitudes towards interracial heterosexual romance from the margins of East African history. It asks why Black/brown intimacy was treated as taboo and denied legitimacy within South Asian diasporic communities in British‐ruled ...

Density and strength variations in the mantle lithosphere affect the distribution of intraplate earthquakes

Communications Earth & Environment
The distribution of earthquakes in stable intracontinental tectonic settings is typically far more diffuse than along plate boundaries and the causative mechanisms underlying some recognizable clustering are not understood.

Spectacle and Spy Stories: The 1954 Royal Commission on Espionage

Australian Journal of Politics &History, EarlyView.
ABSTRACT The Menzies government's 1954 royal commission, established to investigate Soviet espionage in Australia, is well known as the backdrop to the Labor Party split. It saw opposition leader H.V. Evatt's demise and ushered in an almost 20‐year period of Liberal Party governance.

Glofitamab in combination with immunochemotherapy in patients with relapsed/refractory B‐cell non‐Hodgkin lymphoma: Phase 1b dose‐escalation study

British Journal of Haematology, EarlyView.
Summary Glofitamab was investigated with obinutuzumab/rituximab plus cyclophosphamide, doxorubicin, vincristine and prednisone (G/R‐CHOP) in patients with relapsed/refractory B‐cell non‐Hodgkin lymphoma (B‐NHL) who had ≥1 prior obinutuzumab/rituximab‐containing therapy (NCT03467373). The primary end‐point was to determine the optimal biological dose of

Dispersal, source and glass chemistry of a third tephra unit within Iceland's Settlement Layer

Boreas, EarlyView.
Tephra layers may be studied to understand the dynamics and sequence of past explosive volcanism. In Iceland, the distinctive Settlement Layer (AD ~877) underlies almost all archaeological evidence for the Norse Settlement and is preserved in soils across Iceland and as cryptotephra overseas.

Uncertainty of mantle geophysical properties computed from phase equilibrium models

Geophysical Research Letters, 2016
Phase equilibrium models are used routinely to predict geophysically relevant mantle properties. A limitation of this approach is that nonlinearity of the phase equilibrium problem precludes direct assessment of the resultant uncertainties.
