Modeling the Effect of Tramp Oil Contamination on Selective Component Depletion in Metalworking Fluid Systems

open access: yes, 2003
Metalworking fluids are designed to perform specified tasks in the factory. However, these fluids can become contaminated during the manufacturing process by other factory components such as tramp oil.

Quality from Kent: Preliminary results from the analysis of fifth‐ to seventh‐century silver alloys

open access: yesArchaeometry, EarlyView.
Abstract This paper explores early results from the chemical and lead isotope analysis of 30 silver‐alloy objects from southeast England dating between the fifth and seventh centuries CE, presenting limited aspects of the three main analyses that were conducted. First, a comparison of the results gained from surface x‐ray fluorescence (pXRF) values and

Vaporization and Conversion of Ethanolamines used in Metalworking Operations

open access: yesSafety and Health at Work, 2010
Objectives: This study examined how ethanolamines (EAs) with the same functional alcohol group (HOCH2CH2), such as mono-EA (MEA), di-EA (DEA), and tri-EA (TEA), in water-based metalworking fluids (wbMWFs) are vaporized, condensed, and transformed by heat

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

open access: yesArchaeometry, EarlyView.
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.

The Effect of Chip Adsorption on Selective Depletion from a MultiComponent Synthetic Metalworking Fluid

open access: yes, 2003
Some metalworking fluids are designed to coat the surfaces of newly machined metal with rust inhibitors. At some point, these inhibitors are expected to become depleted in the metalworking fluid.

Clinical investigation of an outbreak of alveolitis and asthma in a car engine manufacturing plant [PDF]

open access: yes, 2007
Background Exposure to metal working fluid (MWF) has been associated with outbreaks of EAA in the US, with bacterial contamination of MWF being a possible cause, but was uncommon in the UK.

Early Bronze Age Copper Circulation in the Guadalentín and Segura Valleys (SE Spain)

open access: yesArchaeometry, EarlyView.
ABSTRACT Identifying the sources of copper used in Early Bronze Age metalwork from south‐east Spain is key to resolving a long‐running debate concerning centralized control, or lack thereof, over El Argar society's economic organisation. This study provides the first substantial integrated programme of EDXRF and MC‐ICP‐MS analyses for copper‐base ...
