On Quartz in Amakusa Pottery Stone

Determination of exposure to respirable quartz in the stone crushing units at Azendarian-West of Iran.

The purpose of this study is to describe the personal exposure to respirable dust and quartz and in stone crushing units located at west of Iran. A size of 40 personal samples and 40 stationary samples were obtained and analysis was done by X-ray diffraction (XRD). The results of personal sampling were shown the concentrations of respirable dust exposure level in workers of process, hopper and ...

Pottery Sample Descriptions

Each pottery specimen analyzed was selected on the basis of its potential to reveal information about taxonomic relationships, in addition to providing samples for chemical and mineral analyses. Preference was given to larger sherds with distinct temper and surface treatment characteristics. Table A.1 describes the provenience of the 70 samples. Table A.2 includes the paste and temper character...

Serum copper levels among quartz stone crushing workers: a cross sectional study.

The present cross sectional study was carried out among 134 workers of quartz stone crushing units to assess the serum Cu activity among quartz stone workers without disease. Demographic and occupational details of the subjects were recorded on the predesigned proforma. Standard diagnostic criteria were used for diagnosing silicosis and tuberculosis. The pulmonary functions of the subjects were...

On Estimating the Position of Fragments on Rotational Symmetric Pottery

The archivation of ancient vessel-fragments is a time consuming but important task for archaeologists. The basis for classification and reconstruction is the profile which is the cross-section of the fragment in the direction of the rotational axis of symmetry. Hence the position of a fragment (orientation) on a vessel is important. In this work the estimation of the axis of rotation out of ran...
