A novel in-air PIXE (Particle Induced X-ray Emission) setup was developed which is capable of the fast, sensitive, fully quantitative characterization elemental composition thin and thick samples for elements with Z > 6.

Bone tissue is mineralized dense connective tissue consisting mainly of a mineral component (hydroxyapatite) and an organic matrix comprised of collagens, non-collagenous proteins and proteoglycans (PGs). Extracellular matrix proteins and PGs bind tightly to hydroxyapatite which would protect these molecules from the destructive effects of temperature and chemical agents after death. DNA and pr...

Organic remains can be found in many different environments. They are the most significant source for paleoparasitological studies as well as for other paleoecological reconstruction. Preserved paleoparasitological remains are found from the driest to the moistest conditions. They help us to understand past and present diseases and therefore contribute to understanding the evolution of present ...

Abstract The so-called Triticoid-type grains are known from several prehistoric sites in southwest Asia and their identification has long been unclear. They resemble the of wheats researchers suggested they may represent an extinct Triticeae species, possibly closely related to wild crop progenitors. In this study we identify as Heteranthelium piliferum (Banks & Sol.) Hochst. describe key c...

Metal patch test is often used in clinical settings when metal-induced contact dermatitis is suspected. However, the transdermal permeation behavior of metal ions from the patch test remains unclear. Current patch tests using high concentrations of metal salt solutions have some side effects, e.g. acute skin reactions to high concentrations of metal salt. To resolve these, estimating metal ion ...

aiming to identify and record the prehistoric sites of the mehrān plain, the archaeological survey was carried out during the march of 2010; this, has lid to identifying 36 archaeological sites including tell site, open air site and rock-shelter.of them, 15 sites have attributed to the prehistoric times; of which, the village period sites being studied and presented over this article. overall, ...
