SEM demonstration of elastic fibres in the integument of small and densely-haired mammals.

Asbestos Presence in a Factory that Produced Asbestos-Containing Products

In 2007, research was carried out to determine the type and amount of asbestos fibers in a Croatian factory with a long history of making asbestos-containing products.Since the 1970s, asbestos fibres have been considered carcinogenic in humans i.e as a known cancer-causing agent. In the environment, asbestos fibres are inactive and naturally resist biodegradation. In time, fibres can only be gr...

Pseudoxanthoma Elasticum: A Report of Three Cases in a Family

Pseudoxanthoma Elasticum is an inherited disorder characterized by generalized fragmentation and progressive calcification of the elastic tissues in the dermis, blood vessels and Bruch’s membrane of the eye. Herein, we report 3 patients in a family with pseudoxanthoma elasticum: a father and his two sons.

Nonlinear Thermo-Mechanical Behaviour Analysis of Activated Composites With Shape Memory Alloy Fibres

General thermo-mechanical behavior of composites reinforced by shape memory alloy fibers is predicted using a three-dimensional analytical micromechanical method to consider the effect of fibers activation. Composite due to the micromechanical method can be exposed to general normal and shear mechanical and thermal loading which cause to activate the shape memory alloy fibers within polymeric m...

First investigation of the collagen D-band ultrastructure in fossilized vertebrate integument.

The ultrastructure of dermal fibres of a 200Myr thunniform ichthyosaur, Ichthyosaurus, specifically the 67nm axial repeat D-banding of the fibrils, which characterizes collagen, is presented for the first time by means of scanning electron microscopy (SEM) analysis. The fragment of material investigated is part of previously described fossilized skin comprising an architecture of layers of oppo...
