A method is described for the quantitative analysis of microgram quantities of chrysotile. This method utilizes X-ray diffraction combined with an X-ray absorption correction procedure, based on the use of a silver membrane filter and includes a disp

After the International Agency for Research on Cancer (IARC), Lyon classified crystalline silica within Class I, i.e. substances for which there is clear evidence of carcinogenicity to man, the need was felt for further studies to quantify the concen

The aim of the present work is to study the comminution of tremolite contained in an acid-washed dolomite sample and in a New York talc sample using a gentle, wet, comminution technique. Tremolite in acid-washed dolomite shows a fibrous habit of a le

A quality assurance program for the diffractometric determinations of asbestos in bulk samples is presented. The program, developed upon request of the Italian Health Ministry, includes two tests: the qualitative determination of the asbestos forms p

A scheme for extracting morphological information from images through a edge oriented wavelet decomposition is proposed. Multiresolution edge patterns extracted in the wavelet transform domain are represented by parameterized segments. Tracking these

The IARC has recently included crystalline silica among substances considered carcinogenic for man. This new evaluation immediately posed the need to measure the exposure levels of the general population. The paper reports the results of measurements

In this work, the general problems regarding asbestos determination in bulk samples are discussed. It appears that to date there are no analytical methods that can be considered satisfactory for solving these problems. The approach adopted by the Ist

Exploration oriented seismic modeling requires accurate and efficient methods. A variety of direct modeling methods has been extended and improved within the framework of the EOS-1 project. The aim is to calculate seismograms of the full wavefield in

To determine the asbestos content in a bulk sample by X-ray diffractometry, the sample must be previously comminuted until an adequate granulometry is reached. However, this treatment can produce a decrease in fibre crystallinity which, in turn, caus
