Estimating Baseline Flow Resistance Parameters for Remote Sensing River Discharge (RSQ) From River Morphology Characteristics

JAWRA Journal of the American Water Resources Association, Volume 62, Issue 4, August 2026.
ABSTRACT This study demonstrates that flow resistance in rivers, quantified via calibration of a modified Manning's equation, can inform its estimation from channel hydrometric information available from regional or global datasets for a limited set (N = 14) of rigorously calibrated river reaches in Alaska and with less certainty in a large set (N ...

EFFECTIVE SEPARATION OF GALENA CONCENTRATE FROM THE MIXTURE OF GALENA AND QUARTZ BY TABLING

Global Journal of Engineering Research, 2002
La séparation d'un concentré de galène (sulfure de plomb) propre du mélange de galène et de quartz par une opération de dépôt a été étudiée. Le minerai de plomb nigérian était composé principalement de sulfure de plomb et de quartz. La méthode de tarage a été utilisée sur le minerai comme méthode de concentration par gravité.

The Provenance of Silver in the Viking‐Age Hoard From Bedale, North Yorkshire

Archaeometry, Volume 68, Issue S4, Page S86-S106, July 2026.
ABSTRACT The acquisition of silver was a key motive propelling the Viking expansion out of Scandinavia; identifying the sources of Viking silver during the early part of the Viking Age can provide critical insights into the relative significance of western European and eastern, Islamic wealth in the Viking expansion.

Textural and geochemical analysis of chalcopyrite, galena and sphalerite across the Mount Isa Cu to Pb-Zn transition: Implications for a zoned Cu-Pb-Zn system

, 2020
The genesis of the Mount Isa Cu-Pb-Zn system, northern Australia, is highly debated. Three metallogenic models have previously been proposed to explain the close spatial relationship between a world-class Cu and Pb-Zn deposit: (1) ca.
