Mineralogical appraisal and beneficiation tests on some industrial minerals from Zambia [PDF]

open access: yes, 1991
In March 1990, a visit to Zambia was made by D A Briggs of the Mineralogy and Petrology Group on behalf of the British Geological Survey/Overseas Development Administration project "Minerals for Development". The visit, which was described in Technical

The hidden science of haptics: A pedagogical review of tactile evaluation in cosmetics

open access: yesInternational Journal of Cosmetic Science, EarlyView.
This review explores the physiological basis of tactile perception and critically examines classical and emerging sensory methods used in cosmetics, advocating for broader methodological integration and recognition of sensory analysis in the field. Abstract Sensory analysis is a cornerstone of cosmetic development, yet remains underrepresented in peer ...

The effect of depressant sesbania gum on the flotation of a talc-containing scheelite ore

open access: yesJournal of Materials Research and Technology, 2019
Sodium silicate (SS) has been widely used as a depressant for the scheelite flotation. However, low selectivity and large amount of SS remains a tough problem.

Interplay Between Mechanical and Petrochemical Models on the Fluid Extraction From Subduction Zones

open access: yesJournal of Metamorphic Geology, EarlyView.
ABSTRACT The breakdown of hydrous minerals during subduction results in a densification of the rocks, producing volume changes that can trigger fluid pressure fluctuations and hydrofracturing. These volume changes are controlled by the Clapeyron slope of the reaction and are quantified here using a macroscopic framework that integrates a zero ...

Early Contrast Enhancement: a novel Magnetic Resonance Imaging biomarker of pleural malignancy [PDF]

open access: yes, 2018
Introduction: Pleural Malignancy (PM) is often occult on subjective radiological assessment. We sought to define a novel, semi-objective Magnetic Resonance Imaging (MRI) biomarker of PM, targeted to increased tumour microvessel density (MVD) and ...

Avicenna on the PSR and Causal Necessity in the Natural World

open access: yesTheoria, EarlyView.
ABSTRACT Avicenna's account of causal necessity in the natural world is a key part of his metaphysical system and it is also historically significant. Yet, there is little scholarly discussion of the philosophical basis of his view. This is surprising not only because the topic is important, but also because the view is challenging to interpret ...

Creep of Talc at Subduction Zone Conditions: Implications for Slow Slip and Strength of the Lithosphere

open access: yesGeophysical Research Letters
Talc can strongly influence the rheological properties of the subduction interface. Despite geologic evidence for talc at the interface, and proposed links between its rheology and slow slip events, few experiments have been conducted on talc at relevant

Dehydration kinetics and thermochemistry of selected hydrous phases, and simulated gas release pattern in carbonaceous chondrites [PDF]

open access: yes
As part of our continued program of study on the volatile bearing phases and volatile resource potential of carbonaceous chondrite, results of our experimental studies on the dehydration kinetics of talc as a function of temperature and grain size (50 to
