Once penetrated into the lungs of exposed people, asbestos induces an in vivo biomineralisation process that leads to the formation of a ferruginous coating embedding the fibres. The ensemble of the fibre and the coating is referred to as asbestos body and is believed to be responsible for the high toxicological outcome of asbestos. Lung tissue of two individuals subjected to prolonged occupati...

OBJECTIVES To compare the clearance rate, the related pathology, and the chemical and morphological changes of three man made mineral fibres (MMMFs) in the sheep model of pneumoconiosis. METHODS Fibrous particles were extracted from lung parenchyma and analysed by transmission electron microscopy (TEM) and energy dispersive spectroscopy (EDS). RESULTS The concentration of MMMF11, MMMF21, re...

This paper deals with the composition and properties of solid solution calcium sulfoferrite. It was studied an influence s sulfoferrite on structure cement phases. Study hydration processes mineral are observed only short prismatic crystals. Prismatic crystals ferruginous ettringite always formed from any fraction. it found that smaller initial hydrating grains minerals, faster they hydrated. A...

A forgotten synonymy between Stenocorus vittatus Fabricius, 1801 and Cerambyx globosus Olivier, 1795 (= Xystrocera globosa) is corroborated. Consequently, the former is removed from Alloesia Chevrolat, 1862, and formally excluded from the Brazilian fauna. Key-Words: Alloesia; Brazil; Synonymy; Xystrocera. Head ferruginous. Thorax rounded, shortened, rough, ferruginous, with great dark-blue ring...

Haematite and haematite bearing rocks is a common raw material in Palaeolithic. Widespread in nature, it occurrs either in isolated oucrops or in privileged litostratigraphic formations (in Central Europe these are Lower Devonian, Lower Permian, Lower Triassic and Upper Triassic rocks). All must have provoked an interest of Palaeolithic people so we have searched for a fingerprint for all. So f...

Early Paleozoic bottom waters were mainly ferruginous, like the Neoproterozoic, with a shift to increased euxinia in Devonian.

The expansion of humans and their related infrastructure is increasing the likelihood that wildlife will interact with humans. When disturbed by humans, animals often change their behaviour, which can result in time and energetic costs to that animal. An animal's decision to change behaviour is likely related to the type of disturbance, the individual's past experience with disturbance, and the...
