INTRODUCTION In the Pacific Northwest of North America, archaeological saImonid remains have great potential to inform on issues of prehistoric cultural use, salmonid paleobiology and past environments. One hindrance to using prehistoric salmonid remains has been the gross level of taxonomic identification generally achieved. Species diagnostic elements are rarely found in archaeological contex...
abstract governing was disorganized for years, when mongols attached to iran and it caused to clearing way for interference of mongols princes. dispatching of holaku to the west culminated in establishing iilkhanan government. holakus activities in destruction of abbaasis government and activities which shows his staying in iran, made force oulus juji to comparison against iilkhanis gover...
This article provides an overview of bone composition and the taphonomic processes that affect the representation of skeletal elements in archaeological deposits. Soil chemistry and composition, bone size, and other variables affect these processes.
Background: The method of proton induced X-ray emission (PIXE) has been widely used as a sensitive technique to trace elemental analysis in both biological and medical fields. The sensitivity of this powerful method is in the order of ppm .The aim of this work is to analyze structural composition of 4 heavy trace elements with Z greater than 24 (Mn, Fe, Cu, Zn) in two kinds of gallstones and to...

archaeologically, the hybrid and mythological motif of people-scorpion, as presented in both forms of man-scorpion and woman-scorpion, in the horizon of bronze age cultures in the plateau of iran, merely, is reported from the archaeological sites of jiroft in the halil rood basin, southwest iran. in mesopotamia, the people-scorpion is presented as the guardian monster for the gates of dead peop...
4000 years of human dietary evolution in central Germany, from the first farmers to the first elites
Investigation of human diet during the Neolithic has often been limited to a few archaeological cultures or single sites. In order to provide insight into the development of human food consumption and husbandry strategies, our study explores bone collagen carbon and nitrogen isotope data from 466 human and 105 faunal individuals from 26 sites in central Germany. It is the most extensive data se...
Since two decades ago with the increase in dam construction projects in Iran, a major part of the ancient and historic sites of the country went under water. As mostly, do not exist desirable and sufficient relationship between Iranian Cultural Heritage, Handicraft and Tourism Organization (ICHHTO) and other organizations like Ministry of Energy, the budget allocated to the study of ar­chae...
Two selected examples of PIXE microanalysis in ecophysiology have been shown. Studies of heavy metal distribution in mycorrhizal and nonmycorrhizal roots of Plantago lanceolata showed different mechanisms in filtering of Zn/Pb and Fe/Mn, both enabling plants to cope with metals present in the environment. Studies of the mechanism used by the beetle Chrysolina pardalina to eliminate excessive am...
Characterization of soil corrosivity in archaeological sites is an important subject to understand the conservation conditions of archaeological bronze collections and helps conservators to prepare a conservation strategy for long term preservation of bronze objects. In this paper, a research approach is established to identify soil corrosivity in two archaeological sites and to find correlatio...
