Notable Impact of Paleotectonic Stress on Gold Mineralisation in the West Qinling Orogen

Geological Journal, EarlyView.
By applying fuzzy clustering and multiple inverse methods, we systematically processed the data of vein and fault slip in this ore deposit to reveal the transition of orogenic geological environment and paleotectonic stress field. Our research results show two different stress states: the northwest–southeast extensional stress field and the northeast ...

Characteristics, properties and limitations of per‐ or polyfluoroalkyl substances (PFASs) and fluoropolymers

Polymer International, EarlyView.
An overview and categorization of man‐made per‐ or polyfluoroalkyl substances (PFASs) including low‐molar‐mass and high‐molar‐mass fluorochemicals, and their international regulations is presented. Though certain PFASs are toxic, bioaccumulative and cross the human cellular membranes, others, such as fluoropolymers, are safe, reliable and involved in ...

An Acoustical Machine Learning Approach to Determine Abrasive Belt Wear of Wide Belt Sanders

2022 IEEE Sensors, 2022
This paper describes a machine learning approach to determine the abrasive belt wear of wide belt sanders used in industrial processes based on acoustic data, regardless of the sanding process-related parameters, Feed speed, Grit Size, and Type of material.

Sargassum Lung Syndrome: Air Flow Obstruction and Bronchial Inflammation Are Observed After Prolonged Exposure to Sargassum Gas Emissions in the Eastern Caribbean

Environmental Toxicology, EarlyView.
ABSTRACT Sargassum inundation of Caribbean and American shorelines is a growing environmental hazard. Hydrogen sulfide (H2S) and ammonia (NH3) produced by decomposing Sargassum could be involved in airway obstruction and bronchial inflammation. The study was undertaken to evaluate the effects of exposure to H2S and NH3 gases emitted during Sargassum ...

What Was ‘Middle Australia’? Social Categorisation and Political Positioning in the Late‐20th Century

Australian Journal of Politics &History, EarlyView.
ABSTRACT ‘Middle Australia’ became a ubiquitous term of social categorisation and political positioning during the latter decades of the 20th century. This article examines how this concept was variously used in the metropolitan print media in the guises of the Sydney Morning Herald and The Age of Melbourne, including in their reporting of federal and ...

The Functional Role and Molecular Characterization of the Therapeutic Target CLDN6 in Germ Cell Tumors

Andrology, EarlyView.
ABSTRACT Background The tight junction protein CLDN6 has been identified as a cancer‐associated cell surface marker that is rarely expressed in healthy tissues. In testicular germ cell tumors (GCT), CLDN6 is particularly detectable in seminomas, embryonal carcinomas, and choriocarcinomas.

Out in the cold? A review of Early Middle Palaeolithic settlements in northern Central Europe, age data and geological preconditions for site formation and preservation

Boreas, EarlyView.
The characteristics of settlement of Neanderthals in northern Central Europe during the earlier phases of the Middle Palaeolithic (Marine Isotope Stage 8–6) have been a matter of debate for decades, specifically regarding the population dynamics at such latitudes during the coldest phases. In this paper, we review the known archaeological record of the

Wear study of structured coated belts in advanced abrasive belt finishing [PDF]

Surface and Coatings Technology, 2015
Abstract Advanced belt finishing process is remarkably simple and inexpensive. The principle of operation is simple: pressure-locked shoes platens circumferentially press an abrasive coated belt on a rotating workpiece. This abrasive machining process reduces significantly surface irregularities subsequently improving geometrical quality and ...
